The second mounting position 303 is configured to be connected and matched with the power module 100, so that the surface wet cleaner module 300 and the power module 100 are assembled to form a surface wet cleaner to perform a surface wet cleaner mode. In this state, the power supply assembly 101 is electrically connected to the surface wet cleaner module 300, and the first flow path is in communication with the third flow path.
In the cleaning device, the vacuum cleaner module 200 and the surface wet cleaner module 300 are provided separately. In performing cleaning, the surface wet cleaner module 300 can be configured to clean the ground as needed, and the vacuum cleaner module 200 can be configured to clean the three-dimensional space. The power module 100 can be assembled with the surface wet cleaner module 300 and the vacuum cleaner module 200 respectively to form a surface wet cleaner and a vacuum cleaner, which can provide power for them. The vacuum cleaner module 200 and the surface wet cleaner module 300 share the same power module 100, which saves a set of power module 100 compared to the combination of a surface wet cleaner and a vacuum cleaner, optimizes the structure of the product, and reduces production costs. Specifically, after the power module 100 and the vacuum cleaner module 200 are assembled together, there are at least three aspects of cooperation and connection. Firstly, the power module 100 and the vacuum cleaner module 200 will be matched and connected in physical structure to achieve the stability of the connection between the power module 100 and the vacuum cleaner module 200. Secondly, the power source assembly 101 of the power module 100 and the vacuum cleaner module 200 are electrically connected to provide stable power output for each electrical component in the vacuum cleaner module 200 by the power source assembly 101. Thirdly, the first flow path of the power module 100 will be matched and connected to the second flow path of the vacuum cleaner module 200, suction airflow is generated by the motor assembly 102 to suck air in the external environment into the second flow path, and then into the first flow path, which is finally discharged into the vacuum cleaner module 200 through the first flow path and discharged to the external environment through the vacuum cleaner module 200, achieving airflow circulation. Similarly, after the power module 100 and the surface wet cleaner module 300 are assembled together, there are at least three aspects of coordination and connection. Firstly, the power module 100 and the surface wet cleaner module 300 will be physically matched and connected to achieve the stability of the connection between the power module 100 and the surface wet cleaner module 300.

Preferably, the power module 100 is engageable with the filter assembly 203, that is, one end of the power module 100 and one end of the filter assembly 203 are mutually inclusive. Most preferably, the end of the filter assembly 203 is sleeved outside the power module 100. On one hand, the way of engaging the power module 100 with the filter assembly 203 can achieve rapid assembly between the power module 100 and the filter assembly 203 and improve the stability of the connection between the power module 100 and the filter assembly 203. On the other hand, the way of engaging can reduce the lateral size of the product to a certain extent, making the product more portable when in using.
The axial dimension of the engaging part of the power module 100 and the filter assembly 203 can be specifically designed as needed, preferably being 3-10 mm. As an implementation in some embodiments, a first protrusion 104 can be formed on the end of the power module 100 that is fitting with the filter assembly 203. The diameter of the first protrusion 104 is smaller than that of the housing 2031. When performing assembly, the first protrusion 104 can be engaged with an end of the filter assembly 203, and the end faces of the filter assembly 203 abuts the housing 2031 to complete the engaging therebetween.
As shown in
In some embodiments, the motor assembly 102 is closer to the second assembly surface 109, compared with the power supply assembly 101, that is, in the vacuum cleaner, the motor assembly 102 is disposed between the filter assembly 203 and the power supply assembly 101. Since the motor assembly 102 is heavier than the power supply assembly 101, when the power module 100 is mounted on the vacuum cleaner module 200, the heavier motor assembly 102 is located in the middle of the vacuum cleaner, which can avoid the rear of the vacuum cleaner being heavier, making it easier for the user to hold and providing a better user experience.
Specifically, the area of the power module 100 where the first assembly surface 108 is located forms a second protrusion 112, which protrudes from the periphery of the cylinder structure of the power module 100. On one hand, the second protrusion 112 can make a certain limitation in fitting with the first mounting position 204 or the second mounting position 303 to assist in positioning assembly, and on the other hand, can be configured to set up the relevant structure of the first electrical connection 106. The second protrusion 112 can avoid increasing the diameter of the columnar structure of the power module 100, maintaining the advantage of not providing a handle for the power module 100, so that the power module 100 can meet the performance requirements of the power supply assembly 101 and the motor assembly 102 while also meeting the need for one-handed holding.
In some embodiments, the second protrusion 112 can be provided only in the middle region of the axial length of the power module 100. In some embodiments, the second protrusion 112 can extend along the axial direction of the power module 100 to the end where the second assembly surface 109 is located, as shown in
In some embodiments, the diameter of the power module 100 is 84-100 mm, which can be corresponding to the size for holding by human hand, and it is unnecessary to design a special holding structure for the power module 100 to facilitate the assembly, disassembly, and movement of the power module 100 by human hand. Since the power module 100 is not provided with a special handle structure, it needs to be held by one hand for taking and placing. The diameter of the power module 100 is too large, which may cause the operator to be unable to hold it with one hand. If the diameter of the power module 100 is too small, the power source assembly 101 and the motor assembly 102 inside the housing 103 cannot meet the performance requirements. The diameter of the power module 100 can be further optimized to be 84 mm-95 mm. The range of the ratio of the diameter of the power module 100 to the diameter of the motor assembly 102 inside can be selected as 1.2-2.5, and the range of the power of the motor assembly 102 is preferably 80 W-350 W.
In order to further optimize the structural layout of the vacuum cleaner module 200, the ratio of the diameter of the power module 100 to the diameter of the dust collection assembly 202 ranges from 0.7 to 1.1; after the power module 100 is matched and mounted in the first mounting position 204, the ratio of the lateral length of the vacuum cleaner module 200 to the lateral length of the exposed part of the power module 100 is 1.3-1.7. The lateral length and its ratio of the vacuum cleaner module 200 are required to meet the requirements of power performance on the one hand, while taking into account the overall layout of the vacuum cleaner, during designing. When the ratio of the lateral length of the vacuum cleaner module 200 to the lateral length of the exposed part of the power module 100 is 1.3-1.7, the power module 100 can cooperate with the vacuum cleaner module 200 to meet the corresponding power performance, and the center of gravity of the overall structure of the vacuum cleaner is closer to the middle of the vacuum cleaner, making the overall layout more compact and harmonious. When the user grasps the grip part 205 to move the vacuum cleaner, the user may have a better experience and the user experience is improved. The ratio of the longitudinal height of the vacuum cleaner module 200 to the longitudinal height of the grip part 205 is 1.8-2.8, the ratio of the lateral length of the vacuum cleaner module 200 to the longitudinal height is 1.3-1.6. The above structural design can make the overall dimensions of the vacuum cleaner module 200 more harmonious in both the horizontal and vertical directions, and the layout is more compact.
In order to improve the portability of the vacuum cleaner module 200 in using, the ratio of the diameter of the power module 100 to the weight of the vacuum cleaner module 200 is preferably in a range of 46-91 mm/kg. With the above proportional relationship being achieved, in a preferred embodiment, the lateral length of the vacuum cleaner module 200 is 310-350 mm, after the power module 100 is fitted and mounted in the first mounting position 204, the total lateral length of the filter assembly 203 and the power module 100 is 270-230 mm; after the power module 100 is fitted and mounted in the first mounting position 204, the lateral length of the exposed part of the power module 100 is 160-190 mm; the diameter of the dust collection assembly 202 is 90-115 mm; the longitudinal height of the vacuum cleaner module 200 is 220-240 mm; the longitudinal height of the grip part 205 is 85-120 mm, which can effectively reduce the overall height of the vacuum cleaner, thereby avoiding the height from being too high and the power module 100 located above from shaking, while also ensuring sufficient height space to allow a person's hand to reach in for holding operation. The sucking power of the vacuum cleaner module 200 is 15 W-90 W.
In this embodiment, the housing of the power module is made of plastic with high thermal conductivity (such as PA6, PA, PA66). The heat inside the power module can be transferred outside by means of the high thermal conductivity of the power module.
When the housing of the power module is made of plastic with high thermal conductivity, the housing has an “ice-like” effect. At room temperature, when a person holds the housing, they can clearly feel the cooling effect. This is because the thermal conductivity of this kind of housing is extremely high, and when the person touches the housing, the housing can quickly transfer the temperature of the person's hand outside, so that fast heat conduction and dissipation can be achieved, thus making user has an ice-like feeling. In order to achieve this effect, the thermal conductivity of the housing is no less than 1.5 W/(m·K). In this embodiment, preferably, the thermal conductivity of the housing is 2.5 W/(m·K).
In order to achieve the detachable assembly of the power module 100 and the vacuum cleaner module 200, the power module 100 is provided with a clamping part 105, and the top shell 2051 of the vacuum cleaner module 200 is provided with a first snap-fit element 206. After the power module 100 is matched and mounted in the first mounting position 204, the first snap-fit element 206 can be matched and connected with the clamping part 105, thereby the longitudinal position of the power module 100 and the vacuum cleaner module 200 is under limitation. Preferably, the first snap-fit element 206 is movably disposed on the top shell 2051, and the top shell 2051 is further provided with a locking part 207. The locking part 207 is configured to provide elastic driving force to the first snap-fit element 206, so that the first snap-fit element always has a tendency to move away from the filter assembly 203. The locking part 207 is preferably a spring. Specifically, the locking part 207 abuts the first snap-fit element 206 and moves the first snap-fit element 206 to the extreme position away from the filter assembly 203, so that the first snap-fit element 206 and the clamping part 105 are matched and clamped with each other.
In addition, in the embodiments of the present disclosure, both the vacuum cleaner module 200 and the surface wet cleaner module 300 are provided with electrical and physical buttons. The physical button can be, but not limited to, an unlock button, which is configured to achieve the detachable connection of the power module 100 with the vacuum cleaner module 200 and the surface wet cleaner module 300. The unlock button provided on the vacuum cleaner module 200 in the embodiments of the present disclosure is referred to as the first unlock button 213, and the unlock button provided on the surface wet cleaner module 300 is referred to as the second unlock button 314, for distinction.
For example, in order to adjust the locking part 207 and the first snap-fit element 206, the vacuum cleaner module 200 further includes a first unlock button 213, which is a physical button as mentioned above. The first unlock button 213 is fixedly connected to the first snap-fit element 206 and protrudes outside the vacuum cleaner module 200 for user's control. During the assembly of the power module 100, the first snap-fit element 206 is in the extreme position under the action of the locking part 207, and at this time, the power module 100 interferes with the first snap-fit element 206 during the assembling, to drive the first snap-fit element 205 to move against the driving force of the locking part 207, and make the first snap-fit element 205 snapped into the clamping part 105, and the locking part 207 enables the stable clamping of the first snap-fit element 205 and the clamping part 105. When it is necessary to remove the power module 100, it can be done by applying a force on the filter assembly 203 toward the first unlock button 213, and the first snap-fit element 205 is driven to squeeze the locking part 207, causing the first snap-fit element 205 to move toward the filter assembly 203 against the driving force of the locking part 207. The first snap-fit element 205 eventually disengages from the clamping part 105, to allow the power module 100 to be removed.
Furthermore, as shown in
In order to achieve electrical connection between the power module 100 and the vacuum cleaner module 200, a first electrical connector 106 is provided on the first assembly surface 108 of the power module 100, and a second electrical connector 208 is provided on the top shell 2051 of the vacuum cleaner module 200. After the power module 100 is fitted and mounted in the first mounting position 204, the first electrical connector 106 and the second electrical connector 208 can be mated and connected with each other, thereby achieving electrical connection between the power module 100 and the vacuum cleaner module 200. An accommodation space is formed inside the grip part 205 for accommodating various circuit structures and control circuit boards.
In some embodiments, the dust collection assembly 202 includes a dust cup 2021 and a multi-cone cyclone separator disposed inside the dust cup 2021. The dust cup 2021 has a dust collection space inside, and the suction assembly 201 is provided on the dust cup 2021 and is in communication with the dust collection space. A multi-cone cyclone separator 2022 is provided inside the dust collection space to separate dust from the suction airflow. After the external airflow enters the multi-cone cyclone separator 2022, the separated dust particles are discharged into the dust cup 2021, and the separated airflow enters the filter assembly 203 from the top. A cover 2023 that can be opened is disposed at the bottom of the dust cup 2021 to open the dust collection space at any time to discharge the collected dust, and the multi-cone cyclone separator 2022 can be further removed to be cleaned. The angle between the axis of the multi-cone cyclone separator 2022 and the axis of the power module 100 is 30°-150°, so that the airflow path is a multi-segmented line, which is more harmonious and compact in the overall structure of the machine compared to a straight airflow path. More preferably, the angle between the axis of the multi-cone cyclone separator 2022 and the axis of the power module 100 is 90°. In order to obtain better dust-air separation performance, the ratio of volume of the dust collection assembly 202 to the volume of the vacuum cleaner module 200 is 2.5-6. Preferably, the vertical orthogonal projection of the power module 100 in the vacuum cleaner is at least partially coincident with the dust cup 2021 of the dust collection assembly 202, or the vertical orthogonal projection of the motor assembly 102 in the power module 100 is at least partially coincident with the dust cup 2021 of the dust collection assembly 202, so that the overall weight distribution of the machine is more balanced and the structure is more compact.
The filter assembly 203 in the vacuum cleaner module 200 is configured to further filter the suction airflow passing through the dust collection assembly 202. The filter assembly 203 includes a housing 2031 and a filter core 2032. The housing 2031 can be integrally formed with the dust cup 2021 of the dust collection assembly 202. The filter core 2032 is preferably a HEPA filter core 2032 to achieve better filtration. The power module 100 is provided with a third snap-fit element 113 at one end of the second assembly surface 109. When the power module 100 is assembled on the vacuum cleaner module 200, the third snap-fit element 113 can be buckled and connected to the housing 2031 of the filter assembly 203, which can effectively reduce the assembly gap. When the power module 100 is assembled on the surface wet cleaner module 300, the third snap-fit element 113 can be buckled and connected to the surface wet cleaner module 300, which can also effectively reduce the assembly gap.
In some embodiments, the vacuum cleaner module 200 has a fourth flow path in addition to the second flow path. After the power module 100 is assembled on the vacuum cleaner module 200 to form a vacuum cleaner, the air flow path of the vacuum cleaner during operation is the second flow path, the first flow path, and the fourth flow path in sequence. Specifically, the fourth flow path is provided inside the housing 2031 of the filter assembly 203, and extends along the axial direction of the filter assembly 203. The end of the filter assembly 203 facing the second assembly surface 109 of the power module 100 has third air opening(s) 209 located in the middle and fourth air opening(s) 210 provided around the third air opening(s) 209. In the embodiments, the fourth air openings 210 may be further configured to provided surrounding the third air opening(s) 209. The third air opening(s) 209 serves as the outlet of the second flow path and is configured to communicate with the first air opening 110 of the power module 100. The fourth air opening(s) 210 serve as the inlets of the fourth flow path and is configured to communicate with the second air opening 111 of the power module 100. During operation of the vacuum cleaner, the first flow path of the power module 100 is matched and communicated with the second flow path of the vacuum cleaner module 200 through the first air opening 110, and matched and communicated with the fourth flow path of the vacuum cleaner module 200 through the second air opening 111. After the motor assembly 102 is started, it generates suction airflow, which draws air from the outside into the second flow path. The airflow in the second flow path passes through the third air opening(s) 209 and the first air opening 110 in sequence and enters the first flow path. The airflow in the first flow path then passes through the second air opening 111 and the fourth air opening(s) 210 in sequence and enters the fourth flow path of the vacuum cleaner module, and finally is discharged to the external environment through the fourth flow path, achieving airflow circulation.

The handle 306 can be further provided on the body 302, and is located at the top of the surface wet cleaner module 300 for the user to hold and control the surface wet cleaner module 300 by the buttons thereon. In order to allow the user to maintain an upright position as much as possible when using the cleaning device, without having to bend too much, and improve user's experience, an extension section 307 is provided between the handle and the body 302. The extension section 307 can be further designed to have a telescopic mechanism to adapt users of different heights, facilitating user access and improving operability.
The sewage tank 304 is configured to store the sewage sucked through the suction port of the floor brush 301. The sewage tank 304 is provided on the body 302, and thus the structure of the whole machine can be made compact and the inconvenience of using the floor brush 301 with a large volume of the whole machine can be prevented. The sewage tank 304 can be detachably connected to the body 302, so that the sewage tank 304 can be removed from the body 302 separately for cleaning.
The floor brush 301 is provided with a suction port, which is connected to the sewage tank 304 through a suction pipe, such as a flexible pipe. The body 302 is provided with an exhaust pipe, one end of which is connected to the sewage tank 304, and the other end is located at the second mounting position 303, which is configured to be connected with the first flow path of the power module 100. That is, the third flow path includes the suction port, the suction pipe, the sewage tank 304, and the internal space of the exhaust pipe, which are connected in sequence. When the power module 100 is working, negative pressure is generated in the third flow path, to generate suction force. The airflow sucks the dirt near the suction port from the suction port and takes the dirt from the suction pipe to the sewage tank 304. Then, the airflow takes some of the airflow from the sewage tank 304 into the exhaust pipe, and finally into the first flow path of the power module 100, which is discharged outside by the power module 100.
The clear water tank 305 is configured to contain cleaning solution such as clear water and detergent. The floor brush 301 is provided with a nozzle, and the clear water tank 305 and the nozzle are connected through a clear water pipe. After the cleaning solution in the clear water tank 305 is pumped out, it flows through the clear water pipe to the nozzle, which sprays the cleaning solution onto the to-be-cleaned surface or the roller brush 3011 of the floor brush 301, enabling the floor brush 301 to quickly clean the to-be-cleaned surface.
In the embodiment of the present disclosure, the clear water tank 305 and the sewage tank 304 are respectively disposed on the opposite sides of the main body 302. It is preferred to place the sewage tank 304 on the front side of the main body 302 and the clear water tank 305 on the rear side of the main body. The axes of the clear water tank 305 and the sewage tank 304 are preferably provided in parallel. The suction port of the floor brush 301 and the main body of the roller brush 3011 are also located on the front side of the surface wet cleaner module 300. The air flow path may be reduced and air flow loss may be decreased by providing sewage tank 304 on the front side of the main body 302.
In some embodiments, the second mounting position 303 is located on the side of the sewage tank 304 away from the floor brush 301. That is, after the power module 100 is mounted in the second mounting position 303, the power module 100 is disposed on the side of the sewage tank 304 away from the floor brush 301. Specifically, the front side of the body 302 is provided with a second mounting position 303 for mounting the power module 100 and a third mounting position 308 for mounting the sewage tank 304. A fixed part 309 protruding from the surface of the body 302 is provided between the second mounting position 303 and the third mounting position 308. The side of the fixed part 309 close to the floor brush 301 is configured to cooperate with the sewage tank 304, and the side of the fixed part 309 away from the floor brush 301 is configured to be assembled with the power module 100. The exhaust pipe can be directly provided in the fixed part 309 to be in communication with the sewage tanks 304 and the power module 100 on both sides. In some other embodiments, the second mounting position 303 is located on the side of the clear water tank 305 away from the floor brush 301, i.e., after the power module 100 is mounted in the second mounting position 303, the power module 100 is disposed on the side of the clear water tank 305 away from the floor brush 301.
As shown in FIGS., after the power module 100 is fitted and mounted in the second mounting position 303, the axis of the power module 100 is parallel or coincident with the axis of the sewage tank 304. The inlet of the first flow path is located at one end of the power module 100 in the axial direction, and the inlet of the first flow path is sealedly connected to the outlet of the exhaust pipe on the fixed part 309. Preferably, the power module 100 is inserted and fitted with the fixed part 309, that is, one end of the power module 100 and one end of the fixed part 309 are mutually inclusive. Most preferably, the end of the fixed part 309 is sleeved outside the power module 100. On one hand, the way of engaging the power module 100 with the fixed part 309 can achieve rapid assembly between the power module 100 and the fixed part 309 and improve the stability of the connection between the power module 100 and the fixed part 309. On the other hand, the way of such engaging can make the center of gravity of the power module 100 closer to the brush 301 to a certain extent, save users' effort and improve user experience in using. The axial dimension of the engaging parts of the power module 100 and the fixed part 309 can be specifically designed as needed, preferably being 3-10 mm. As an implementation in some embodiments, a first protrusion 104 is formed at the end of the power module 100 that is fitted with the fixed part 309. The diameter of the first protrusion 104 is smaller than that of the housing 2031. During assembly, the first protrusion 104 can be matched and inserted into the end of the fixed part 309, and the end surface of the fixed part 309 and the end surface of the housing 2031 are abutted to complete the insertion and fitting of the two parts.
In some embodiments, the fresh water tank 305 and the power module 100 have been at least partially overlapped in the extension direction of the body 302, or the power source assembly 101 in the power module 100 and the fresh water tank 305 have been partially overlapped, and the fresh water tank 305 and the sewage tank 304 have been at least partially overlapped in the extension direction of the body 302. The power module 100 includes the power source assembly 101 and the motor assembly 102, which are heavy, while the fresh water tank 305 and the sewage tank 304 are loaded with a large amount of liquid in using, therefore the spatial layout of the three directly affects the center of gravity of the surface wet cleaner module 300 as a whole, thereby affecting the user's experience. With the above layout settings, it is possible to ensure that the center of gravity positions of the fresh water tank 305, the sewage tank 304, and the power module 100 are maximally close to each other, so that the center of gravity of the device can be lower, making it easier to operate and providing a better user's experience.
In order to further optimize the structural layout of the surface wet cleaner module 300, the ratio of the diameter of the body 302 to the diameter of the power module 100 is 0.9-1.3; after the power module 100 is matched and mounted in the second mounting position 303, the ratio of the axial length of the body 302 to the axial length of the exposed part of the power module 100 is 3.4-4; the ratio of the diameter of the body 302 to the weight of the surface wet cleaner module 300 is 16.8-25 mm/kg. With the above proportional relationship, in a preferred embodiment, the diameter of the body 302 is 95-115 mm; after the power module 100 is matched and mounted in the second mounting position 303, the body 302 is in a vertical state, and the distance in vertical from the top of the power module 100 to the bottom of the floor brush is 610-660 mm; after the power module 100 is matched and mounted in the second mounting position 303, the body 302 is in a vertical state, and the distance in vertical from the bottom of the exposed part of the power module 100 to the bottom of the base or the bottom of the floor brush is 420-510 mm.
In order to achieve the detachable assembly between the power module 100 and the surface wet cleaner module 300, the body 302 of the surface wet cleaner module 300 may be provided with a second snap-fit element 313. After the power module 100 is fitted and mounted in the second mounting position 303, the second snap-fit element 313 can be matched and connected with the clamping part 105, thereby enabling the stable connection of the power module 100 and the surface wet cleaner module 300. As shown in
In some embodiments, the surface wet cleaner module 300 has a fifth flow path in addition to the third flow path. After the power module 100 is assembled on the surface wet cleaner module 300 to form a surface wet cleaner, the air flow path of the surface wet cleaner during operation is the third flow path, the first flow path, and the fifth flow path in sequence. Specifically, the fifth flow path is disposed inside the body 302, and the fixed part 309 has a fifth air opening 311 located in the middle and a sixth air opening 312 disposed around the fifth air opening 311 at one end facing the second assembly surface 109 of the power module 100. The fifth air opening 311 serves as the outlet of the third flow path and is configured to communicate with the first air opening 110 of the power module 100. The sixth air opening 312 serves as the inlet of the fifth flow path and is configured to communicate with the second air opening 111 of the power module 100. During operation of the surface wet cleaner, the first flow path of the power module 100 is matched and communicated with the third flow path of the surface wet cleaner module 300 through the first air opening 110, and is matched and communicated with the fifth flow path of the surface wet cleaner module 300 through the second air opening 111. The airflow in the first flow path passes through the fifth air opening 311 and the first air opening 110 in sequence and enters the first flow path. The airflow in the first flow path then passes through the second air opening 111 and the sixth air opening 312 in sequence and enters the fifth flow path of the surface wet cleaner module 300. Finally, the airflow is discharged through the assembly gap of the body 302 to the external environment through the fifth flow path, achieving airflow circulation.
In addition, in order to quickly disassemble and assemble the handle 306 of the surface wet cleaner module 300, a handle quick release button 316 is provided on the top of the back of the body 302 of the surface wet cleaner module 300. The handle quick release button 316 is a recessed button, and the outer surface of the recessed button is lower than the contour surface of the top of the back of the body 302, which can prevent accidental touch. When the handle quick release button 316 is pressed, the handle 306 can be quickly removed from the body 302. When the handle 306 is to be reassembled, the handle 306 can be inserted into the handle plug-in tube 317 on the top of the body 302 until the bottom of the handle 306 is engaged and fixed with the handle plug-in tube 317.
In some embodiments, the power module 100 of the present disclosure may be provided with no buttons, and the buttons of the cleaning device are all provided on the vacuum cleaner module 200 and the surface wet cleaner module 300, which can limit the function of the power module 100 to only providing energy and power, making the product structure of the power module 100 more simply, facilitating the reduction of product volume and improving the feasibility of one-hand grasping.
The vacuum cleaner module 200 and the surface wet cleaner module 300 are both provided with electrical and physical buttons. When the power module 100 is mounted on the vacuum cleaner module 200, the physical buttons on the vacuum cleaner module 200 are configured to control the locking of the vacuum cleaner module 200 and the power module 100, and the electrical buttons on the vacuum cleaner module 200 are configured to control the operation of the power module 100. Similarly, when the power module 100 is mounted on the surface wet cleaner module 300, the physical buttons on the surface wet cleaner module 300 are configured to control the locking of the surface wet cleaner module 300 and the power module 100, and the electrical buttons on the surface wet cleaner module 300 are configured to control the operation of the power module 100.
The physical buttons on the vacuum cleaner module include a first unlock button 213, and the electrical buttons include a power button 214 and a mode button 215. For example, the buttons that may be provided on the vacuum cleaner module 200 include but not limited to the first unlock button 213, the power button 214, and the mode button 215. These buttons can be located at the upper end of the handle and within the reach of the thumb and index finger when the handle is gripped. As shown in the figure, the mode button 215 can be located at the end of the first mounting position 204, and the first unlock button 213 is located on the left side of the entire machine, so that the pressing direction of the first unlock button 213 faces the filter assembly 203 for easy operation.
Due to the fact that the power module 100 may no longer be provided with buttons, the power module 100 can be used as a controlled component after docking with the vacuum cleaner module 200 or the surface wet cleaner module 300. Specifically, when the switch button on the vacuum cleaner module 200 or the surface wet cleaner module 300 is pressed, the Trig trigger signal can be sent to the power module 100, and the power source assembly 101 of the power module 100 is awakened to start providing external power. The electrical signal is then transmitted to the vacuum cleaner module 200 or the surface wet cleaner module 300, which then sends the control signal to the motor assembly 102 of the power module 100 by a Tx terminal. The motor assembly 102 performs corresponding work according to the control signal. The display screen of the power module 200 displays different content when it is connected to the vacuum cleaner module 200 and the surface wet cleaner module 300, respectively. For example, the display screen may display the relevant content of the vacuum cleaner module 200 or the surface wet cleaner module 300. The display screen of the power module 200 is located at the end of the power module 200 away from the second assembly surface 109, which is convenient for users to check during use.
The cleaning device provided by the embodiments of the present disclosure can be combined with the vacuum cleaner module 200 and the surface wet cleaner module 300 by a detachable power module 100, and thus the cleaning device may serve as both a vacuum cleaner and a surface wet cleaner, and can be used in multiple cleaning scenarios and achieve multi-purpose use by one machine. In addition to the power supply assembly 101 for power supply and the motor assembly 102 for providing the power for air flow, it may be further necessary to add a display screen 116 and a WiFi module 117 on the power module 100. The display screen 116 is configured to facilitate the interface display of the power module 100 after the power module 100 is removed from either one of the vacuum cleaner module 200 and the surface wet cleaner module 300 and mounted on the other. The WiFi module is used for network distribution and OTA upgrade. In addition, a first main control MCU chip 217 for communication connection with the power module 100 is provided in the vacuum cleaner module 200, and a second main control MCU chip 315 for communication connection with the power module is provided in the surface wet cleaner module 300. The power source assembly 101 includes a battery pack and a battery control unit. In related technologies, the battery control unit is a combination of MCU chips and battery protection analog front-end (AFE). Due to insufficient serial port resources in the MCU chips, it cannot simultaneously support the communication functions of the battery pack, display screen 116, WiFi module 117, first main control board 217, and second main control board 315. Specifically, the power module 100 communicates with the first main control MCU chip 217 of the vacuum cleaner module 200 through only one pair of serial ports, and the power module 100 communicates with the second main control MCU chip 315 of the surface wet cleaner module 300 through only one pair of serial ports, while it is necessary to simultaneously transmit messages from the AFE module, display screen 116, WiFi module 117, and motor assembly 102. In this case, the actual delay of communication will become very high, data loss may be incurred correspondingly. In the OTA upgrade of the battery pack, the amount of data required to be transmitted by the WiFi module is too large, and thus such transmission needs the majority of the bandwidth of the serial port communication. However, due to the large amount of information to be transmitted with limited transmission bandwidth, it may be impossible to implement the OTA upgrade function of the battery pack.
In view of the above, the embodiments of the present disclosure further improve the cleaning device.
In some embodiments, as shown in
In the above embodiment, the first main control MCU chip 217 or the second main control MCU chip 315 cannot directly control the battery pack, the display screen 116, the WiFi module 117 and the motor component 102m, and has to conduct the control by means of the forwarding MCU chip 119, but there is only one communication serial port between the forwarding MCU chip 119 and the first main control MCU chip 217 or the second main control MCU chip 315. The transmission speed may be increased by increasing the main frequency of the first main control MCU chip 217 or the second main control MCU chip 315, but the bandwidth is limited and cannot meet the requirement of transmitting so much communication information at the same time. In view of this, in some embodiments, as shown in
In the above two embodiments, the first main control MCU chip 217 of the vacuum cleaner module 200 or the second main control MCU chip 315 of the surface wet cleaner module 300 is used as the core control center to control the power module 100. In another embodiment, as shown in

During the cleaning process of the cleaning device, the roller brush comes into contact with the to-be-cleaned surface, and the driving device drives the roller brush to rotate, so that the to-be-cleaned surface may be cleaned Specifically, the roller brush cavity extends along the axial direction of the roller brush, and a transmission base is provided in the roller brush cavity. The output end of the driving device extends into the roller brush cavity and is detachably connected to the transmission base in the roller brush cavity to drive the roller brush to rotate.
In addition, a transmission mechanism is provided between the transmission base and the output end of the driving device. The transmission mechanism includes a transmission part and a cooperating part that are engaged and fitted together. When the transmission part and the cooperating part are assembled together, the transmission part is configured to drive the cooperating part to be locked therewith during forward and reverse rotation. The transmission part and the cooperating part of the present disclosure are fitted together in a detachable manner. When it is required to remove the roller brush, the roller brush can be disengaged from the driving device; the roller brush can be engaged together with the driving device during assembly. The locking together in the present disclosure refers to the tendency of the transmission part and the cooperating part to move closer to each other during the forward rotation or reversal of the roller brush, without the tendency to disengage from each other. Therefore, during the cleaning process of the cleaning device, the locking between the cooperating part and the transmission part can effectively avoid disengagement between the transmission base and the driving device. The safety in using the cleaning device may be improved to certain level.
The cleaning device of the present disclosure has an interference fit between the to-be-cleaned surface and the roller brush during cleaning process, and the driving device can drive the transmission base to drive the roller brush in forward and reverse rotations to perform cleaning. The roller brush can be prevented from rotating in the same direction for a long time, which may result in the bristles of the roller brush too close to the body. The cleaning ability of the roller brush can be improved with service life extended by switching the rotation direction of the roller brush.
For better understanding, the specific structure and working principle of the cleaning device of the present disclosure are described in detail below with reference to
The present disclosure provides a cleaning device, which can be a handheld cleaning device such as a handheld cleaning machine, a handheld vacuum cleaner, a handheld surface wet cleaner, etc., which are well known to those skilled in the art. It can also be a self-moving cleaning device, such as a sweeping robot, a surface wet cleaner robot, or a robot that integrates functions of sweeping and scrubber, for to-be-cleaned surfaces such as floors, sofas, and carpets that need to be cleaned.

One end of the driving device 624 is fixedly connected to the body 600. During assembly, referring to
In one implementation of the present disclosure, the rolling brush 621 is in contact with the to-be-cleaned surface, and the external structure of the rolling brush 621, such as the bristles, gradually contact the body of the rolling brush 621 during long-term work, which may result in a gradual reduction in the interference between the rolling brush 621 and the to-be-cleaned surface, and the cleaning effect of the cleaning device becomes worse. At this time, the rotation direction of the rolling brush 621 can be changed by changing the current rotation direction of the driving device 624. In this way, it can be avoided that the rolling brush 621 performs cleaning work in a single direction for a long time, which may result in excessive fitting of the bristles and the body, and the water attached to the bristles can only stay on the surface of the rolling brush 621, eventually forms a layer of water film on the outer surface of the rolling brush 621, and water marks may be left on the to-be-cleaned surface during work and affecting the cleaning effect. Therefore, with the rotation direction of the rolling brush 621 changed by the driving device 624, the stability of the external structure of the rolling brush 621 may be maintained, the rolling brush 621 may be protected, the service life of the rolling brush 621 may be extended, and the cleaning performance of the rolling brush 621 may be improved. During cleaning on the to-be-cleaned surface performed by the cleaning device, the rolling brush can be driven to rotate forward or reverse; or when the cleaning device is placed on the base station for self-cleaning, the rolling brush can be driven to rotate forward or reverse.
In an embodiment of the present disclosure, in driving the cooperating part to rotate forward and reverse, the transmission part 625 is located on disengage path of the cooperating part to prevent the cooperating part from being disengaged. That is, during the cooperating part is driven by the transmission part 625 to rotate forward, the transmission part 625 is located on disengage path of the cooperating part; during the cooperating part is driven by the transmission part 625 to rotate reverse, the transmission part 625 is located on disengage path of the cooperating part, thereby the cooperating part may be prevented from being disengaged from the transmission part 625 during the forward or reverse rotation.
During disassembly, the roller brush 621 can be directly removed from the driving device 624. During the removal process, the transmission part 625 and the cooperating part in the transmission mechanism can be easily disengaged from each other, thereby the roller brush 621 may be removed from the driving device 624 for maintenance, cleaning, and other operations.

Similarly, when the second transmission part 6252 and the second abutting part 6264 are combined together, the position of the turning point between the first transmission part 6251 and the second transmission part 6252 is fitted with the second turning point 6266 between the second abutting part 6264 and the second extending part 6265, so that the stability may be improved during the reverse rotation, and the transmission part may be thus locked with the second abutting part 6264 and the second extending part 6265.
In addition, the overall shape of the first abutting part 6261 and the first extending portion 6262 is the same as that of the second abutting part 6264 and the second extending portion 6265. Alternatively, the second abutting part 6264 can be formed as the first extending portion 6262, and the first abutting part 6261 can be formed as the second extending portion 6265, which is also beneficial for processing and preparation. The production cost may be significantly reduced by using same structure for components, compared to using irregular structure, which is beneficial for production and manufacturing.
With reference to the view direction of
In one embodiment of the present disclosure, with reference to the view direction of
In another embodiment of the present disclosure, when the transmission part 625 rotates clockwise with the cooperating part under the driving of the driving device 624, i.e., when it rotates in reverse, with reference to
It should be noted that whether the transmission part 625 and the cooperating part are in a “∨” or “∧” structure can be selected and designed by those skilled in the art as needed, and no limitation would be applied thereto in the present disclosure.
In one embodiment of the present disclosure, with reference to
In another embodiment of the present disclosure, the first abutting part 6261 and the first extending portion 6262 are both in the shape of a circular arc, and the second abutting part 6264 and the second extending portion 6265 are both in the shape of a circular arc.
In one embodiment of the present disclosure, in order to further simplify the structure among the first abutting part 6261, the first extending portion 6262, the second abutting part 6264, and the second extending portion 6265, the present embodiment may only keep the first abutting part 6261 and the second abutting part 6264. As long as the first abutting part 6261 can cooperate with the transmission part 625 to rotate forward and the second abutting part 6264 can cooperate with the transmission part 625 to rotate in reverse under the driving of the driving device 624, no limitation would be applied thereto in the present disclosure.
In one embodiment of the present disclosure, with reference to
In practical using, the control unit can be communicatively connected to the driving device 624, and the control unit is configured to issue control signals to the driving device 624, so as to control the driving device 624 to switch of the rotation direction of the roller brush 621. Since the first direction is opposite to the second direction, the rotation direction of the roller brush 621 can be changed during the cleaning operation of the cleaning device 6. The damage to the structure of the roller brush 621 due to long-term rotation in a single direction may be avoided, and thus the roller brush 621 may be protected and the interference between the roller brush 621 and the to-be-cleaned surface can always be maintained within a relatively stable range. This effectively improves the cleaning effect and service life of the roller brush 621.
The second embodiment is same as the first embodiment except that the transmission part is provided on the transmission base 622. The output end 6241 of the driving device 624 has a transmission cavity, and the cooperating part is a fitting groove provided on the transmission cavity. The first abutting part and the second abutting part are groove walls on the opposite sides of the fitting groove. Alternatively, the first abutting part and the second abutting part are ribs provided on the inner wall of the transmission cavity, and the first abutting part and the second abutting part enclose to form a fitting groove. Specifically, the specific arrangement between the transmission part, the fitting groove, the first abutting part, and the second abutting part is the same as that in the first embodiment, and those skilled in the art can fully implement the arrangement based on the description in the first embodiment, and repeated description is omitted here to avoid abundancy.
In one embodiment of the present disclosure, a roller brush assembly 62 is further provided. The roller brush assembly 62 includes a roller brush 621 and a driving device 624. The roller brush 621 has a roller brush cavity 6211 extending in its axial direction, and a transmission base 622 is disposed in the roller brush cavity 6211. The output end 6241 of the driving device 624 extends into the roller brush cavity 6211 and is detachably connected to the transmission base 622 to drive the roller brush 621 to perform rotation.
A transmission mechanism is provided between the transmission base 622 and the output end 6241 of the driving device 624, and the transmission mechanism includes a transmission part 625 and a cooperating part that are engaged and fitted together. The transmission part 625 is configured to be locked with the cooperating part in driving the cooperating part to perform forward and reverse rotation.
The structure and connection relationship of the roller brush assembly in this embodiment are exactly the same as those of the roller brush assembly 62 described above, and its connection method for engagement with the cleaning device in using is also exactly the same as those of the roller brush assembly 62 described above. Those skilled in the art can derive the structure of and the way of using the roller brush assembly in this embodiment directly based on the description above, and therefore no further detailed explanation is provided here.
In one embodiment of the present disclosure, a roller brush assembly is further provided and includes a roller brush 621 and a driving device 624. The roller brush 621 has a roller brush cavity 6211 extending in its axial direction, and a transmission base 622 is provided in the roller brush cavity 6211. The output end 6241 of the driving device 624 extends into the roller brush cavity 6211 and is detachably connected to the transmission base 622 to drive the roller brush 621 to perform rotation. A transmission mechanism is provided between the transmission base 622 and the output end 6241 of the driving device 624, and the transmission mechanism includes a transmission part 625 and a cooperating part, both of which are in the shape of V or arc and are engaged and fitted together. The transmission part 625 is configured to be locked together with the cooperating part in driving the cooperating part to rotate forward and in reverse.
The structure and principle of the transmission part 625 and the cooperating part in this embodiment are the same as those in the above embodiment, and repeated description is omitted here to avoid abundancy.
The technical solutions adopted by the cleaning device in the present disclosure are explained below in conjunction with specific application scenarios to facilitate understanding. In the following application scenarios, the cleaning device is described as a handheld scrubber.
Application Scenario 1
When a user pushes the handheld scrubber to clean the to-be-cleaned surface, the user can move the holding part of the surface wet cleaner on the ground and use the roller brush assembly 62 to clean the to-be-cleaned surface. With reference to
With reference to
Similarly, with the action of the output end 6241 of the driving device 624, the transmission base 622 can drive the roller brush 621 to rotate reversely. During the rotation, the surface the second abutting part 6264 contacting the transmission part 625 forms a second locking side. The second locking side can also prevent the transmission base 622 from loosening and being disengaged from the driving device 624 during rotation.
In this way, the direction of rotation of the roller brush 621 may be changed by the driving device 624, so that the bristles on the roller brush 621 may not remain in the same direction for a long time but always remain in a fluffy state, and thus the roller brush 621 can be protected and the cleaning power of the roller brush 621 may be increased. At the same time, the first locking side and the second locking side have the same structure as the first abutting part 6261 and the second abutting part 6264, it is further possible to effectively avoid the loosening and separation of the transmission base 622 from the driving device 624 in the axial direction of the roller brush 621, and thus the safety in using the cleaning device may be improved.
Application Scenario 2
When the roller brush 621 wears out or has malfunctions due to being used for a long time, it needs to be replaced. The width of the fitting groove 626 of the present disclosure is greater than or equal to the width of the transmission part 625, and the transmission part 625 is configured to be detachably connected to the fitting groove 626 by engaging. Therefore, during disassembling the roller brush 621, the first locking side and the second locking side may not prevent the transmission base 622 from moving away from the driving device 624 since there is some freedom between the fitting groove 626 and the transmission part 625. The user can simply and easily disassemble driving device 624 from the transmission base 622 by rotating the driving device 624.
Similarly, during the assembly of the roller brush 621, the user simply aligns the transmission part 625 with the fitting groove 626, and rotates it in the circumferential direction of the roller brush 621 after insertion, the driving device 624 and the transmission base 622 are locked together to complete the assembly after a first locking side is formed between the first abutting part 6261 and the first transmission part 6251, or a second locking side is formed between the second abutting part 6264 and the second transmission part 6252. This solves the problem of there is difficulty in disassembly and assembly the roller brush 621 from the driving device 624, and user's experience is thus degraded. With a simple and quick disassembly method, the user's experience may be improved.
It should be noted that the cleaning device of the present disclosure can be applied not only to the above-mentioned handheld surface wet cleaner, but also to other devices that require a roller brush assembly to achieve cleaning of the to-be-cleaned surface, such as surface wet cleaner robot, sweeping-scrubber device, etc. Detailed examples may be not listed in the present disclosure.
With reference to
In view of the above problems, the embodiments of the present disclosure provide a cleaning device and a power source device that solve the above problems, so as to reduce the noise generated by the cleaning device in using.
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. It is apparent that the described embodiments are only a part of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope as claimed by the present disclosure.
In one embodiment of the present disclosure, a cleaning device is provided and include a main body 10 and a power source device 700 disposed on the main body 10. The main body 10 provides a supporting body for the assembly of the power source device 700, and the power source device 700 provides suction force for the cleaning device when the cleaning device is used, and is configured to suck sewage from the to-be-cleaned surface to clean the to-be-cleaned surface.
The power source device 700 can be fixedly mounted on the main body 10. Alternatively, as shown in

According to different needs, the muffler cover 722 can be buckled at least on the periphery of the main body section, i.e., the muffler cover 722 can be buckled on the periphery of the main body section. Alternatively, the muffler cover 722 can be buckled on the periphery of the main body section, and a part of the muffler cover 722 can be buckled on the suction section. There is a second air path 7224 between the outer wall of the muffler cover 722 and the inner wall of the first accommodation chamber 711, and the second air path 7224 and the first air path 7214 form an air outlet path 712.
Further, the muffler cover 722 is located at least partially above the outlet of the air inlet path 7211. With reference to
A second implementation of the muffler cover 722 may be that the outlet 721a of the air inlet path 7211 and the lowermost air guiding hole 722a of the muffler cover 722 are located on two sides of the separation line 7215, so that the air flowing out of the outlet 721a of the air inlet path 7211 flows upward through the muffler cover 722, an extension path may be formed by the gap between the muffler cover 722 and the motor 721. The extension path extends the flow path of the air path.
A third implementation of the muffler cover 722 is that, along the radial direction of the motor 721, the muffler cover 722 has a center line 7225, and the outlet 721a of the air inlet path 7211 and the center line 7225 of the muffler cover 722 are located on two sides of the separation line 7215. This implementation allows more than half of the muffler cover 722 to be located on one side (or above) of the outlet of the air inlet path 7211.
The examples corresponding to the second and third implementations described above are not shown in the drawings of the description.
In order to better extend the air outlet path 712 to effectively reduce high-frequency wind noise, in some embodiments of the present disclosure, an air opening of the first air path 7214 away from the second air path 7224 is the air outlet hole 7121 of the air outlet path 712. In this way, taking the orientation of
As shown in
Further, to avoid the rotation of the main body section 7212 caused by the rotation of the impeller of the motor 721, in some embodiments of the present disclosure, with reference to
In order to enable the airflow to flow as guided by the air path, in some embodiments of the present disclosure, in connection with

For example, one assembly way may be as follows:
First, with reference to
After that, with reference to
Then, with reference to
Finally, with reference to
After assembly, there is a second air path 7224 between the muffler cover 722 and the upper cover of shell 71a, and there is a first air path 7214 between the inlet sealing sleeve 724 and the lower cover of shell 71b. The air guiding hole of the muffler cover 722 is located above the outlet of the air inlet path 7211, and the air outlet hole 7121 is located below the muffler cover 722. The vibration isolation and sealing between the motor 721 and the lower cover of shell 71b can be achieved by using the inlet sealing sleeve 724, and the vibration isolation and sealing between the motor 721 and the muffler cover 722 can be achieved by using the inlet sealing sleeve 724 and the shock-absorbing pad 723. The vibration isolation and sealing between the motor assembly 72 and the upper cover of shell 71a can be achieved by using the shock-absorbing pad 723.
The air flow path after assembly is as follows, with reference to
The arrows in
When the motor 721 is working, the external air enters the air inlet path 7211 through the opening on the lower cover of shell 71b. Then, the airflow enters the air path between the muffler cover and the motor through the air inlet path 7211, so that the flow path of the airflow may be extended. At the same time, the air guiding holes 722a evenly provided on the muffler cover 722 are configured to adjust the airflow, forcing the airflow to bypass the muffler cover 722 and pass through the side of the muffler cover 722 away from the air inlet path 7211, that is, the airflow enters the air outlet path through the guiding holes of the muffler cover 722.
Then, the airflow coming out of the air guiding hole enters the second air path 7224 between the muffler cover 722 and the upper cover of shell 71a, flows through the second air path 7224 into the first air path 7214 between the inlet sealing sleeve 724 and the lower cover of shell 71b, and finally flows out of the power source device 700 through the air outlet holes 7121 provided on the lower cover of shell 71b.
With reference to
Further, a heat dissipation air path is provided between the first receiving cavity and the second receiving cavity, which can be connected to the air path between the motor and the muffler cover and the air outlet path 712. The airflow can enter the second receiving cavity through the heat dissipation air path, flow through the battery pack assembly 73 to dissipate heat from the battery pack assembly 73, and then flow out through the air outlet path 712 after heat exchange.
With reference to
The display assembly 74 may be connected to the upper cover of shell 71a via the mounting part 7412. The display assembly 74 can be further connected to the battery pack assembly 73, which provides power to the display assembly 74. A sealing ring 7412 can be placed in the sealing ring groove 7411. During assembly, the sealing ring 7412 is located between the display screen 742 and the mounting part 7412, to prevent substances such as water from entering the power source device 700 and the display assembly 74 through the gap between the display assembly 74 and the power source shell 71, which may damage the electrical components inside the power source device 700 and the display assembly 74. At the same time, the overall modularization of the display assembly 74 is achieved by integrating the display screen 742 on the main body 741 and assembling the display assembly 74 by the mounting part 7412 on the main body 741, so that the problems of a large number of parts, a dispersed distribution, and a large number of gaps may be avoided.
With reference to
Based on the above embodiments, with reference to
It should be noted that the implementation of the power source device 700 can refer to the implementations described in the above embodiments, provided that there is no conflicts in the structures. The power source device 700 is the same as the one described in the above embodiments, and detailed description is omitted to avoid abundancy.
The technical solutions adopted in the present disclosure are explained below in conjunction with specific application scenarios to facilitate understanding.
Application Scenario 1
The user cleans the floor with a handheld cleaning device. The user starts the handheld cleaning device, and the power source device 700 starts to generate negative pressure. The dirt such as sewage is sucked into the sewage tank 14 with the airflow through the floor brush assembly 12. The sewage and airflow are separated in the sewage tank 14, and the sewage collects in the sewage tank 14. The air flows out of the sewage tank 14 through the air outlet holes of the sewage tank 14 and enters the power source device 700.
At this time, the airflow enters the air inlet holes of the air inlet path 7211 and enters the air inlet path 7211 inside the motor 721. Then, the airflow enters the air path between the motor and the muffler cover through the air inlet path 7211, to extend the flow path of the airflow. At the same time, the guiding holes 722a evenly provided on the muffler cover 722 are configured to adjust the airflow, to force the airflow to bypass the muffler cover 722, pass through the top of the muffler cover 722, and enter the air outlet path through the air guiding holes, so that the flow path of the air inlet path 7211 may be extended. Due to the extension of the flow path of the air inlet path 7211 and the air outlet path 712, and the airflow is adjusted through the guiding holes 722a on the muffler cover 722, high-frequency wind noise can be effectively reduced and the noise of cleaning device can be reduced.
Application Scenario 2
On the basis of application scenario 1, the flow path of the air inlet path 7211 and the air outlet path 712 is extended, and the airflow through the air guiding hole 722a on the muffler cover 722 is adjusted, the high-frequency wind noise is effectively reduced, and the noise of the cleaning device is reduced, the vibration isolation and sealing between the motor 721 and the lower cover of shell 71b are implemented by using the inlet sealing sleeve 724, and the vibration isolation and sealing between the motor 721 and the muffler cover 722 are implemented by using the inlet sealing sleeve 724 and the shock-absorbing pad 723. The vibration isolation and sealing between the motor assembly 72 and the upper cover of shell 71a are implemented by using the shock-absorbing pad 723, so that the noise caused by vibration may be reduced and the noise of the cleaning device is reduced.
In addition to noise reduction, current cleaning device further has a problem in cooling the battery. Cleaning device, such as surface wet cleaners, vacuum cleaners, are increasingly interested by users for their size, weight, safety, charging time, and other characteristics. Battery cooling is inextricably related to size, space, and arrangement, and cannot be achieved simultaneously. Therefore, it is necessary to make full use of the assembly of components and the arrangement of cells in a limited space to solve the problem of battery pack. The following will focus on improving the power source device of cleaning device from the perspectives of battery cooling, overall size optimization, and ease of operation.
The battery pack assembly 73 is disposed above the motor 721, as shown in
The cell 731 can be a soft-pack battery. A single cell 731 is rectangular, as shown in
In an implementation, two adjacent cells 731 are separated at the end by foam, which may provide space for expansion due to heating of the soft-pack battery, and facilitate the passing of cooling airflow. As shown in
Furthermore, each cell is provided in parallel, and the end faces can be misaligned. This arrangement occupies less space and distributes heat evenly among the cells.
It should be noted here that the above-mentioned electrical connection part 77 refers to the part of the power source device 700 configured to be connected with the main body 10. The electrical connection part 77 can be a protrusion on the power source device, which can be set only in the middle region of the axial length of the power source device. In some embodiments, the electrical connection part 77 can extend along the axial direction of the power source device to the assembling end face of the power source device 700 and the main body 10. A recess matched with the protrusion can be provided at corresponding position on the main body for guiding of assembling. Alternatively, the cleaning device further includes a second body. For example, a product includes a main body and a second body. The main body can be a surface wet cleaner body, and the second body can be a vacuum cleaner module body. Connection structure matched with the electrical connection part 77, such as a recess groove may be provided at corresponding positions on the main body and the second body for guiding of assembling.
The above-mentioned grip part 75 is a part of the power source shell 71 that is convenient for holding the power source assembly with one hand. The grip part 75 can be a recessed structure formed on the power source shell 71. Specifically, the grip part can include two recessed portions on opposite sides of the power source shell 71. The surfaces of the recessed portions are lower than the outer contour surface of the power source shell 71 (the contour surface of the power source shell 71 excluding the recessed portion). When the user holds the power source device, a thumb of one hand holds one of the recessed portions, and the other four fingers of the same hand can hold the other recessed portion. In this way, the user can hold the power source device with one hand for assembling or disassembling.
The bracket of the battery pack assembly 73 is on an assembling side of the cooling fan 76, and other parts except the assembling part for the cooling fan 76 remain closed. In order to prevent airflow from flowing out from this side, as shown in
In another embodiment, as shown in
The positions for providing the cooling fan are exemplarily listed above in
Furthermore, the diameter of the power source shell 71 of the power source device can be 84-100 mm, specifically, the diameter of the power source shell 71 can be 92 mm, which is convenient for one-handed operation. That is, it is unnecessary to design a special holding structure to facilitate the assembling, disassembling, and transfer of the power source device by hand. At the same time, the diameter of the power source shell is limited to 84-100 mm, such as 92 mm, which ensures good heat dissipation while maintaining a small size.
Furthermore, the power source shell can be made of a material with a thermal conductivity greater than 0.7 W/m·k, which helps accelerate heat exchange. In one embodiment, the battery pack assembly 73 located above the motor 721 uses the fan 7 and the power source shell to dissipate heat. The airflow blown by the fan 7 flows through the gaps between adjacent cells and then comes into contact with the power source shell. Since the thermal conductivity of the power source shell is greater than 0.7 W/m·k, heat exchange and heat transfer are very rapid, and the heat can be quickly transferred to outside, and thus the heat from the battery pack assembly 73 may be dissipated.
On the other hand, as shown in
With reference to the embodiment shown in
In another embodiment shown in
The present disclosure further provides an embodiment in which a semiconductor cooling chip 725 is provided above the muffler cover 722 of the motor 721 (as shown in
Please refer to
The cleaning device of the present disclosure may include a floor brush assembly and a sewage tank. The floor brush assembly includes a floor brush shell, a roller brush, and a roller brush cover. The floor brush shell is provided with a suction port, and the roller brush is configured to be rotationally connected to the floor brush shell. During the cleaning of the cleaning device, the roller brush comes into contact with the work surface to clean it, and the suction port can suck the sewage into the sewage tank.
The sewage tank includes a tank body, an end cap bracket, and a water overflow detecting component. The tank body is provided with a sewage inlet path to facilitate the entry of sewage on the working surface into the inner chamber through the sewage inlet path. A water blocking shell with a water blocking cavity is provided on the end cap bracket, and the sewage outlet of the sewage inlet path is configured to extend into the water blocking cavity of the water blocking shell. A water blocking assembly located on a side of the water blocking cavity is provided on the end cap bracket, and the water overflow detecting component is disposed outside the water blocking assembly. The water blocking assembly includes a first water blocking part and a second water blocking part. The first water blocking part is configured to separate the sewage flowing down from the bottom of the water blocking cavity from the water overflow detecting component. There is a gap between the second water blocking part and the side of the water blocking cavity, and the second water blocking part is configured to separate the water overflow detecting component from the gap.
It is understood that the first water blocking part can separate the sewage flowing down from the bottom of the water blocking cavity from the water overflow detecting component, so as to avoid the sewage flowing down from the bottom of the water blocking cavity from falling onto the water overflow detecting component. There is a gap between the second water blocking part and the side of the water blocking cavity, and the second water blocking part can isolate the water overflow detecting component from the gap. Therefore, when the sewage in the water blocking cavity flows down from the gap, the second water blocking part can separate the sewage flowing down from the gap from the water overflow detecting component, so as to avoid the sewage flowing down from the gap from falling onto the water overflow detecting component. The water blocking component of the present disclosure can prevent the water overflow detecting component from misreporting due to the sewage flowing down from the water blocking cavity, ensure the normal operation of the cleaning device, and effectively improve the user experience.
For better understanding, the specific structure and working principle of the cleaning device of the present disclosure are described in detail with reference to
The present disclosure provides a cleaning device for cleaning work surfaces such as floors and carpets. The cleaning device at least includes a sewage tank for storing sewage sucked from the working surface.
It is understood that the cleaning device may further include a body, a floor brush assembly, and a fan assembly. The body serves as a bearing part for mounting various functional components required for the cleaning device. The floor brush assembly is disposed at the bottom end of the body and is used for cleaning the work surface. The floor brush assembly includes a floor brush shell, a roller brush, and a roller brush cover. The floor brush shell is provided with a suction port, and the roller brush is configured to be rotatably connected to the floor brush shell. During the cleaning of the cleaning device, the roller brush comes into contact with the work surface for cleaning of the work surface.
The fan assembly is configured to create negative pressure inside the sewage tank, so that the sewage on the working surface may be sucked into the interior of the sewage tank through the suction port on the floor brush shell under the action of negative pressure. The sewage can include only dirty water, or a mixture of dirty water and solid waste.
As shown in
A water blocking shell 821 with a water blocking cavity 822 is provided on the end cap bracket 82, and the sewage outlet 8121 of the sewage inlet path 812 is configured to extend into the water blocking cavity 822 of the water blocking shell 821. As shown in
The structure of the water blocking shell 821 can have various forms. Specifically, as shown in
In other embodiments of the present disclosure, a sealing wall may be further provided on the other side of the opposing connecting wall 8212, so that the enclosing of the connecting wall 8212, the enclosing side wall 8211, and the sealing wall may form a water blocking cavity 822. There is no limitation in the present embodiment. The water overflow detecting component 83 is configured to be triggered when the sewage tank is in a full state, so as to timely control the floor brush assembly and fan component to stop in time, to avoid overflowing of sewage in the sewage tank, and notify the user to promptly empty the dirty water in the sewage tank.
As shown in
It is understood that the first water blocking part 8241 can separate the sewage flowing down from the bottom of the water blocking cavity 822 from the water overflow detecting component 83, so as to prevent the sewage flowing down from the bottom of the water blocking cavity 822 from falling onto the water overflow detecting component 83. There is a gap 8245 between the second water blocking part 8242 and the side of the water blocking cavity 822, and the second water blocking part 8242 can separate the water overflow detecting component 83 from the gap 8245. Therefore, when the sewage in the water blocking cavity 822 flows down from the gap 8245, the second water blocking part 8242 can separate the sewage flowing down from the gap 8245 from the water overflow detecting component 83, so as to prevent the sewage flowing down from the gap 8245 from falling onto the water overflow detecting component 83. The water blocking assembly 824 of the present disclosure can prevent the water overflow detecting component 83 from making false alarms due to the large amount of sewage flowing out of the water blocking cavity 822, and ensure the normal operation of the cleaning device and effectively improve the user's experience.
In one example, the first water blocking part 8241, the second water blocking part 8242, and the partition part 8243 are integrated on the water blocking assembly 824. The first water blocking part 8241 is formed by downward extension of the enclosing side wall 8211, and the second water blocking part 8242 and the partition part 8243 are formed on the side of the water blocking assembly 824. Of course, in other examples, the first water blocking part 8241, the second water blocking part 8242, and the partition part 8243 can be independent of the water blocking assembly 824.
As shown in
As shown in
With the fixed part 8213, it is convenient for the water overflow detection component 83 to extend down to the target position. Due to the gap between the water overflow detection component 83 and the water blocking part 824, even if some sewage is attached to the water blocking part 824, it is difficult for the sewage to contaminate the water overflow detection component 83, so as to further prevent the water overflow detection component 83 from making false alarms.
Furthermore, as shown in
The water overflow detecting component 83 can be various types of remote water overflow detecting components such as optical detection components and resistance detection components. When the water overflow detecting component 83 is a resistance detection component, in one embodiment of the present disclosure, as shown in
Specifically, as shown in
It is understood that during the normal operation of the cleaning assembly, the sewage on the working surface will be continuously sucked into the inner cavity 811 of the sewage tank. When the sewage tank is in the full state, the measuring point 833 of the first probe 831 and the measuring point 833 of the second probe 832 will both be soaked in sewage. Since the resistance of sewage is much lower than that of air, the first probe 831 and the second probe 832 can be conducted, and the water overflow detection component 83 sends a signal of fullness in the sewage tank to the cleaning device to remind the user to empty the sewage in the sewage tank.
During the operation of the cleaning assembly, when a large amount of sewage falls from the water blocking cavity 822 at the same time, such sewage may contact the measuring points 833 of the first probe 831 and the second probe 832 simultaneously, to make the first probe 831 and the second probe 832 conduct in advance, resulting in a false alarm from the water overflow detection component 83. At this time, the sewage tank has not been in the full state, and only less sewage user can pour from the sewage tank.
When the sewage tank is still and not full, but the end cap bracket 82 is attached with some sewage, and this part of sewage can make the first probe 831 and the second probe 832 conduct, the water overflow detection component 83 may send a full signal to the cleaning device, which may cause false alarms. And only after the user empty this part of sewage, the water overflow detection component 83 can work normally, which not only increases the user's workload, but also affects the user's experience. Therefore, as shown in
It is understood that when the water overflow detecting component 83 includes the first probe 831 and the second probe 832 provided on respective sides of the water blocking shell 821, two corresponding water blocking assemblies 824 are provided on respective sides of the water blocking cavity 822, and the first probe 831 and the second probe 832 are provided outside the corresponding water blocking assembly 824, so as to prevent the sewage falling from the water blocking cavity 822 from landing on the first probe 831 and the second probe 832, and prevent the water overflow detecting component 83 from misreporting due to the large amount of sewage scattered below the water blocking cavity 822.
Furthermore, the measuring points 833 of the first probe 831 and the second probe 832 are located below the bottom edge of the water blocking shell 821 and above the bottom edge of the water stopper 824, therefore when the sewage tank is still and not full, the sewage attached to the end cap bracket 82 needs to bypass the water blocking shell 821 and pass through the measuring points 833 extending downward from the water blocking shell 821 to the first probe 831 and the second probe 832 to conduct the first probe 831 and the second probe 832, which greatly extends the distance required for the sewage to climb the walls, increases the difficulty of conducting the first probe 831 and the second probe 832, and reduces the possibility of conducting the first probe 831 and the second probe 832, so that false alarms from the water overflow detection component 83 may be avoided, and the normal operation of the cleaning device may be ensured, the user's workload may be reduced, and the user's experience may be improved.
In order to further increase the distance required for the dirt attached to the end cap bracket 82 to climb walls, as shown in
In this way, when the sewage tank is standing still and not full, if the sewage attached to the end cap bracket 82 wants to conduct the first probe 831 and the second probe 832, it not only needs to pass through the measuring point 833 extending downward from the water blocking shell 821 to the first probe 831 and the second probe 832, but also needs to bypass the connecting wall 8212 protruding from the edges of the two first water blocking parts 8241 on the water blocking shell 821. It can be seen that with the connecting wall 8212 protruded from the edge of the first water blocking part 8241, the distance required for the sewage to climb walls is further extended, which further increases the difficulty of the sewage to conduct the first probe 831 and the second probe 832, and further reduces the possibility of the sewage to conduct the first probe 831 and the second probe 832, and reduces the possibility of false alarm of the water overflow detection component 83.
In order to further avoid the false alarm of the water overflow detecting component 83 caused by the scattering of a large amount of sewage under the water blocking cavity 822, as shown in
It can be seen that the solid-liquid separation frame 825 can be mounted on the enclosing side wall 8211 or connecting wall 8212 through the open end, and the space enclosed by the solid-liquid separation frame 825 is the aforementioned water blocking cavity 822. The sewage flowing out of the sewage inlet path 812 is configured to flow through the solid-liquid separation frame 825 into the tank body 81.
With a solid-liquid separation frame 825 in the water blocking cavity 822, after the sewage mixed with solid waste flows from the sewage outlet hole 8121 of the sewage inlet path 812 into the water blocking cavity 822, the larger solid waste particles may be blocked by the solid-liquid separation frame 825 and remain in the solid-liquid separation frame 825, while the remaining sewage may flow through the solid-liquid separation frame 825 into the tank body 81. In this way, large pieces of solid waste in the sewage may be prevented from entering the inner cavity 811, so as to prevent large pieces of solid waste from being attached to the outer wall of the water blocking shell 821, which may make sewage flow into the first probe 831 and the second probe 832. Moreover, when users clean the garbage in the sewage tank, it is also convenient for users to separately handle the larger solid waste particles and the remaining sewage, and thus the user's workload may be reduced.
Specifically, as shown in
As shown in
The particle size of the solid waste trapped in the solid-liquid separation frame 825 can be adjusted by adjusting the size of the aperture of the liquid outlet hole 8251 and the liquid leakage hole 8252. The sewage can flow smoothly out of the solid-liquid separation frame 825, while the solid waste in the sewage may be trapped in the solid-liquid separation frame 825 as much as possible, by setting the aperture of the liquid outlet hole 8251 and the liquid leakage hole 8252 to an appropriate size.
As shown in
Furthermore, as shown in
Furthermore, as shown in
With the partition part 8243, sewage may be further prevented from direct flowing from the side of the water blocking shell 821 to the air outlet 823, so as to further avoiding the sewage from being brought by air to bypass the water blocking assembly 824 and reach the vicinity of the water overflow detecting component 83, to prevent the water overflow detecting component 83 from issuing false alarms. Moreover, there is open space between the partition part 8243 and the first water blocking part 8241, so that the air near the water overflow detecting component 83 can flow normally, and the situation may not happen that the water overflow detecting component 83 does not report or reports late after the sewage tank becomes full due to the failure of air to flow normally.
As shown in
As shown in
Moreover, the partition part 8243, the first water blocking part 8241, the second water blocking part 8242, and the water blocking shell 821 are integrally formed, therefore it is possible to save the connection structure among the partition part 8243, the first water blocking part 8241, the second water blocking part 8242, and the water blocking shell 821, and to enhance the connection strength among the partition part 8243, the first water blocking part 8241, the second water blocking part 8242, and the water blocking shell 821, and to reduce the required processing steps of the end cap bracket 82.
Furthermore, as shown in
It is understood that in one embodiment of the present disclosure, the cleaning device is configured to be inclined relative to the working surface during operation; the first probe 831 and the second probe 832 are configured to be located above the partition groove 8244 when the cleaning device is in the working state. That is, taking the direction in
The present disclosure further provides a solution tank, which includes:
The solution tank can effectively avoid false alarms from the water-level detection component 83. The solution tank can be the sewage tank mentioned above, or it can be configured to store other liquids. For specific structure and principle, please refer to the previous description, which is not repeated here.
In one embodiment of the present disclosure, a control method for a cleaning device is further provided, which is implemented by the above-mentioned cleaning device and includes the following steps: when the equivalent resistance of the water overflow detecting component is less than a first threshold value and keeps conductive for a first predetermined time, issuing an overflow signal.
In one embodiment of the present disclosure, when the equivalent resistance of the water overflow detecting component being conducted is greater than the first threshold and less than the second threshold value and keeps conductive for a second predetermined time, issuing an overflow signal.
In the embodiment of the water overflow detecting component 83 of the present disclosure, which includes a first probe 831 and a second probe 832, it is determined whether the current sewage tank is full based on whether the equivalent resistance between the two probes reaches a threshold value and the duration of conduction.
In one embodiment of the present disclosure, for example, when the sewage in the sewage tank reaches the measuring points of the two probes, the two probes are conducted, and it is determined in the detection loop that the equivalent resistance between the two probes is less than the first threshold value, and the two probes are kept being conductive for the first predetermined time, it is concluded that the current sewage tank is in a full state, and thus an overflow signal is emitted.
In one embodiment of the present disclosure, it is determined in the detection loop that the equivalent resistance between two probes is greater than the first threshold value and less than the second threshold value, and the two probes are kept being conductive for the second predetermined time, it is concluded that the current sewage tank is in a full state. This is because the environment in the sewage tank is complex, and foam may be generated on the surface of the sewage when the sewage falls from the water blocking cavity. In addition, when the user holds the cleaning device in the process of cleaning, the sewage may shake in the sewage tank and generate foam on the surface of the sewage. A large amount of foam generated in the waste water bucket may overflow from the waste water bucket. Therefore, when the two probes detect foam, it should also be concluded that the current sewage tank is full of water.
That is, in the present disclosure, two probes are used to detect whether the foam on the surface of the sewage reaches a predetermined height with the sewage. The foam is mixed with air and sewage, therefore when the foam reaches the measuring points of the two probes, the equivalent resistance of the two probes after being conducted is greater than the equivalent resistance of the two probes being conducted by sewage. Therefore, when the equivalent resistance between the two probes is determined to be greater than the first threshold and less than the second threshold in the detection loop, and the two probes are kept being conductive for the second predetermined time, it can be concluded that the current state is a state of being conducted by foam.
The first threshold value and the second threshold value in the present disclosure can be determined according to the specific situation of sewage and foam. In a specific embodiment of the present disclosure, the first threshold value can be 250 kΩ, and the second threshold value can be 350 kΩ, depending on the actual situation of the specific detection loop. In this embodiment, according to the characteristics of foam, the second threshold can be set to 1.1-1.5 times of the first threshold. In addition, the first threshold and the second threshold can also be numerical ranges, which will not be specifically explained here.
In addition, the second predetermined time in the present disclosure can be larger than the first predetermined time, because the situation of the two probes being conducted by foam is more complicated than that of the two probes being conducted by sewage, the second predetermined time used for determining the conductive state by foam is larger than the first predetermined time for determining the conductive state by sewage, so as to avoid the occurrence of accidental triggering. For example, in one embodiment of the present disclosure, the first predetermined time can be 1.5 s, and the second predetermined time can be 5 s, which can be selected according to actual needs. In this embodiment, according to the characteristics of foam, for better accuracy in determining, the second predetermined time is more than 3 times of the first predetermined time. In addition, the first predetermined time and the second predetermined time can also be numerical ranges, which will not be specifically described here.
In other embodiments, it is also possible to determine the overflow state in a variety of different scenarios based on the combination of the equivalent resistances between the two probes and durations. The above description only takes the foam scenario and the liquid scenario as an example.
Application Scenario
The present disclosure provides a cleaning device, which can be a handheld cleaning device, such as a handheld cleaning machine, a handheld vacuum cleaner, a handheld surface wet cleaner, etc., which are well known to those skilled in the art. It can also be a self-moving cleaning device such as a sweeping robot, a scrubber robot, or a robot that integrates functions of sweeping and scrubber for cleaning work surfaces such as floors, sofas, and carpets. In the embodiment of the present disclosure where the cleaning device is a handheld surface wet cleaner, when a user uses the surface wet cleaner for cleaning work, the user can push the surface wet cleaner to move on the floor and use the floor brush assembly of the surface wet cleaner to clean the work surface.
The cleaning device of the present disclosure may include a floor brush assembly and a sewage tank, and the floor brush assembly includes a floor brush shell, a roller brush, and a roller brush cover. The floor brush shell is provided with a suction port, and the roller brush is configured to be rotationally connected to the floor brush shell. During the cleaning of the cleaning device, the roller brush comes into contact with the working surface to clean it, and the suction port can suck the sewage into the sewage tank for disposal.
The sewage tank includes a tank body 81, an end cap bracket 82, and a water overflow detecting component 83. The tank body 81 is provided with a sewage inlet path 812, which facilitates the entry of sewage on the working surface into the inner cavity 811 through the sewage inlet path 812. The end cap bracket 82 is provided with a water blocking shell 821 having a water blocking cavity 822, and the sewage outlet hole 8121 of the sewage inlet path 812 is configured to extend into the water blocking cavity 822 of the water blocking shell 821.

The water blocking assembly 824 includes a first water blocking part 8241 and a second water blocking part 8242. The first water blocking part 8241 is configured to separate sewage flowing down from the bottom of the water blocking cavity 822 from the water overflow detecting component 83. There is a gap 8245 between the second water blocking part 8242 and the side of the water blocking cavity 822, and the second water blocking part 8242 is configured to separate the water overflow detecting component 83 from the gap 8245.
It is understood that the first water blocking part 8241 can separate the sewage flowing down from the bottom of the water blocking cavity 822 from the water overflow detecting component 83, so as to prevent the sewage flowing down from the bottom of the water blocking cavity 822 from falling onto the water overflow detecting component 83. There is a gap 8245 between the second water blocking part 8242 and the side of the water blocking cavity 822, and the second water blocking part 8242 can isolate the water overflow detecting component 83 from the gap 8245. Therefore, when the sewage in the water blocking cavity 822 flows down from the gap 8245, the second water blocking part 8242 can isolate the sewage flowing down from the gap 8245 from the water overflow detecting component 83, so as to prevent the sewage flowing down from the gap 8245 from falling onto the water overflow detecting component 83. The water blocking assembly 824 of the present disclosure can prevent the water overflow detecting component 83 from making false alarms due to the large amount of sewage flowing out of the water blocking cavity 822, and ensure the normal operation of the cleaning device and effectively improve the user's experience.

This is well known to those skilled in the art, and this embodiment will not repeat it.
In another example, the cleaning device is a surface wet cleaner, including a main frame and a main body 920. The main frame is rotationally connected to the main body 920. The main frame is provided with a handle, and the user can push and pull the cleaning device by the handle to complete the floor cleaning. The main frame is further provided with a clear water tank, a recycling tank, a suction source, and a battery, etc. The main body 920 serves as the floor brush of the cleaning device, and is provided with cleaning solution distribution components such as a water spray plate, cleaning parts such as a roller brush, a suction port, etc. The water in the clear water tank is sprayed by the cleaning solution distribution component to the cleaning components or the floor, and the cleaning components move (such as the rotation of the roller brush), the suction source works to generate suction force, and the dirt (sewage and solid waste) is sucked through the suction port to the recycling tank, so as to complete the floor cleaning.
The roller brush assembly 930 is disposed on the main body 920 for cleaning the to-be-cleaned surface. Here, the roller brush assembly 930 is disposed on the side of the main body 920 near the to-be-cleaned surface. Here, the roller brush assembly 930 generally has an axis and can rotate around its axis to achieve the cleaning function. Here, in order to facilitate the description of the positional relationship of various components, in the embodiment of the present disclosure, a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other are used, wherein the first direction X is the forward direction of the cleaning device when it is operating, the cleaning device has a first side and a second side that are opposite along the first direction X. Specifically, the second side is the front side and the first side is the rear side in the forward direction. The second direction Y is parallel to or coincides with the axis direction of the roller brush assembly 930. In view of the fact that the to-be-cleaned surface is usually the ground or a plane that is roughly parallel to the ground, the third direction Z can usually be set to be the vertical direction.
With reference to
The assembly part 91a is configured to be assembled with the main body 920 to fix the relative positional relationship between the cleaning assembly 910 and the main body 920. After the assembly part 91a is connected with the main body 920, the cleaning part 91b is located on the side of the main body 920 close to the to-be-cleaned surface, so that the cleaning part 91b can clean the to-be-cleaned surface. The cleaning part 91b can be a scraper strip or the like, which is configured to scrape water stains on the ground to keep the ground clean. Of course, there is no limitation thereon in the present embodiment. Generally, along the first direction X, the cleaning assembly 910 is provided on the first side of the roller brush assembly 930, that is, the cleaning assembly 910 is located on the rear side of the roller brush assembly 930. Therefore, in using, the roller brush assembly 930 passes through the to-be-cleaned surface first, and then the cleaning part 91b passes through the to-be-cleaned surface.
Here, please refer to
Here, in some examples, when the cleaning device is working, the cleaning device sprays cleaning media such as cleaning solution onto the roller brush assembly 930, and the roller brush assembly 930 wipes the to-be-cleaned surface to make it clean. In addition, the cleaning device is further provided with a suction port, and under the action of the suction source, the sewage containing water is sucked to the sewage container of the cleaning device through the suction port. During the process of sucking the sewage, the sewage may contact the cleaning part 91b and leave a residue of water on the cleaning part 91b, which may leak backward along the assembly gap. Similarly, when the cleaning device is placed on the bearing part 940 for self-cleaning, during the sucking of cleaning media such as cleaning solution, the cleaning media may also contact the cleaning part 91b and leave a residue of water on the cleaning part 91b. Of course, the formation of residual liquid is not limited to the above example, and the residual liquid may further come from the to-be-cleaned surface or from the steam generating component of the cleaning device, etc. This embodiment does not constitute an undue limitation thereon. For example, the steam generated by the steam generating component is sprayed onto the roller brush assembly 930 or the to-be-cleaned surface to better clean the to-be-cleaned surface, and the residual liquid after cleaning will leak backward along the assembly gap. The steam generating component may include a heating body and a pipeline, etc. The pipeline is configured to supply liquid water to the heating body, and output the steam from the outlet of the heating body to the roller brush assembly 930 or the to-be-cleaned surface.
Here, please refer to
When the cleaning device is carried on the bearing part 940, the accumulated liquid may generally accumulate in the area C shown in the figure, which may cause water accumulation in the central area of the bearing part 940.
Therefore, in the embodiment of the present disclosure, with reference to
For example, please refer to
Here, please refer to
Here, if the main body 920 does not have other structures that may interference with protrusions 9111 on the side close to the cleaning assembly 910, the first water passing hole 9112 may not be provided, but the protrusions 9111 may be made to penetrate the assembly part 91a along the second direction Y, so as to prevent residual water from moving to the rear side.

With the blocking by the protrusion 9111, the residual water may move forward and/or to both sides along the second direction Y, so that the residual water may not accumulate in the area behind the protrusion 9111. Preferably, the assembly part 91a gradually slopes toward the to-be-cleaned surface along the first direction X, which can advantageously guide the residual water to flow toward the roller brush side.
Here, the first water passing hole 9112 penetrates the assembly part 91a, and on the side of the first water passing hole 9112 away from the main body 920, the assembly part 91a and the cleaning part 91b extend towards the second side, that is, towards the front side, and gradually incline towards the to-be-cleaned surface along the first direction X. Therefore, the assembly part 91a and the cleaning part 91b are used as a guide to guide the residual water that drops down towards the front side. The liquid flowing down from the first water passing hole 9112 can be attached to the wall and flow towards the roller brush side along the outer wall of the assembly part 91a. Of course, it is understood that in other embodiments, a guide wall that gradually inclines towards the to-be-cleaned surface along the first direction X can be additionally provided to form the guide part, or the guide part may not be specifically provided. This embodiment does not constitute an undue limitation.
In some embodiments, with reference to
