In the technical solutions provided in the embodiments of the present disclosure, the dust collecting pile includes a body 10, a dust barrel 20, and a fan assembly 40.
As shown in
The dust barrel includes a dust bag or a cyclone separator, where the body is selectively mounted with the dust barrel including the dust bag or the dust barrel including the cyclone separator.
The fan assembly 40 is disposed on the body 10, where an air inlet 41 of the fan assembly 40 is communicated with an airflow outlet end 22 of the dust barrel 20, and the fan assembly 40 generates a negative pressure, so as to ensure that the dust within the dust box can enter the dust inlet channel 11 through the dust inlet 111 and allow airflows to circulate. Here, the dust within the dust box includes the debris within the dust box. The fan assembly 40 and the dust barrel 20 have axes which are parallel with each other and perpendicular to a horizontal plane, and are both disposed on the body 10 side by side. Wind that enters an air inlet conduit through the dust inlet 111 and then enters the dust barrel 20 is discharged directly from the airflow outlet end 22 after cyclone separation, the airflows enter and exit horizontally, and air paths are simple and efficient, so that it is not easy to cause dust blockage. Optionally, lower surfaces of the dust barrel 20 and the fan assembly 40 are generally on the same horizontal plane.
Specifically, when the cleaning robot is triggered upon the completion of cleaning, insufficient electric quantity itself or full garbage in the dust box, the cleaning robot may move back to the dust collecting pile to complete charging or unload the garbage in the dust box into the dust collecting pile.
When the cleaning robot moves back to the dust collecting pile, the cleaning robot looks for a dust collecting device through a signal receiving device continuously. The dust collecting pile includes a signal transmitting device, for example, the signal transmitting device transmits communication signals continuously within a certain angle range for the cleaning robot to be captured. When capturing the communication signals, the cleaning robot may determine the position of the dust collecting pile and move to the dust collecting pile by means of a navigation function.
Further, if the cleaning robot starts from the dust collecting pile as cleaning starts, the position of the dust collecting pile may be recorded on a map. Thus, during returning to the dust collecting pile, the cleaning robot optionally goes to the position of the dust collecting pile that has been recorded on the map, determines the position of the dust collecting pile based on the signal transmitting device of the dust collecting pile and moves to the dust collecting pile through the navigation function, so as to reduce the time to look for the dust collecting pile and improve the efficiency of returning to the dust collecting pile.
Optionally, an outer side of the dust inlet 111 may be provided with a sealing ring, an outer side of the rolling brush 112 of the robot is provided with a rolling brush cover 113, and the sealing ring corresponds to a part of the robot body and a part of the rolling brush cover 113. When the cleaning robot moves to the body 10, and a garbage inlet of the cleaning robot is communicated with the dust inlet 111 of the dust inlet channel 11, the fan assembly 40 runs, so that a seal is formed between the garbage inlet of the cleaning robot and the dust inlet 111 of the dust inlet channel 11, so as to suck the dust within the dust box into the dust inlet channel 11.
The lifting structure may allow the rolling brush 112 and the rolling brush cover 113 of the cleaning robot to move in an approximate vertical direction, so as to facilitate better sealing cooperation with the dust inlet 111 and the sealing ring.
After the cleaning robot moves in position, the dust collecting pile in this embodiment can suck the dust within the dust box into the dust barrel 20 for collection through the running of the fan assembly 40, and finally, the airflows are discharged from the fan assembly 40, such that the dust within the dust box of the cleaning robot can be recycled into the dust barrel 20. Therefore, automated processing may be enabled for the whole dust cleaning process.
Optionally, the rolling brush 112 of the robot may rotate counter to a cleaning direction in cooperation with the running of the fan assembly 40, thereby facilitating the fan assembly 40 to better discharge the dust in the dust box.
It should be noted that the dust barrel 20 is detachably disposed on the body 10, so as to facilitate cleaning and replacing of the dust barrel 20.
In an embodiment, as shown in
The cyclone separator 24 includes a primary separation cyclone 241 and a secondary separation cyclone 242. The primary separation cyclone 241 has an axis disposed approximately parallel to that of the secondary separation cyclone 242. After the axis of the primary separation cyclone 241 is disposed approximately parallel to the axis of the secondary separation cyclone 242, the complexity of a wind path in the dust barrel can be reduced greatly, thereby reducing the risk of dust accumulation when the dust that has been collected within the dust barrel increases, and enhancing the overall dust collecting effect of the cyclone separator.
Further, the axes of the primary separation cyclone 241 and the secondary separation cyclone 242 may be coincided completely to make the wind path in the dust barrel more unimpeded.
The secondary separation cyclone 242 may include a plurality of cyclone separators, which are mainly in the shape of a cone with a large upper end and a small lower end and distributed around the axis of the secondary separation cyclone 242 respectively. The arrangement of a plurality of groups of cyclone separators improves the dust separation efficiency of the secondary separation cyclone, and further enhances the dust receiving capacity of the dust collecting pile. The number of the secondary cyclone separators may be nine, twelve, or fifteen, and the larger the number is, the higher the separation efficiency is.
A separation filter screen 243 is disposed in the periphery of the secondary separation cyclone 242. A primary cyclone is formed by an outer surface of the primary separation cyclone 241, an inner surface of the dust barrel 20, and an outer surface of the separation filter screen 243 together. Air separated by the primary cyclone separates larger particle garbage out of the airflows, which falls onto an outer side of the primary separation cyclone 241. The separation filter screen 243 is used for passage of the airflows that enter the secondary separation cyclone 242 after primary cyclone separation. The separation filter screen 243 is optionally a metal filter screen, which may prolong the service life and improve the filtering effect. The separation filter screen 243 is an annular mesh, and a support frame of the primary separation cyclone 241 is used to settle a bottom of the separation filter screen 243. The particle garbage filtered out by the separation filter screen 243 is gathered under the support frame of the primary separation cyclone 241. An outer edge of the support frame of the primary separation cyclone 241 may extend downward to form a skirt shape to prevent the particle garbage separated by the primary cyclone from moving upward.
The secondary separation cyclone 242 further includes a sealing end cover 246. The sealing end cover 246 is an annular plate distributed around an axis of the sealing end cover 246 in a rotary manner for sealing the airflows passing through the separation filter screen 243. A sealing space is formed by the separation filter screen 243, an inner wall of the primary separation cyclone 241, and the sealing end cover 246 to seal a secondary cyclone of the airflows passing through the separation filter screen 243. Each secondary separation cyclone 242 forms a gas-solid separation cyclone, and separated solid particle garbage falls into an inner side of the primary separation cyclone 241. The sealing end cover 246 and the bottom of the separation filter screen 243 may also not on the same horizontal plane according to practical situations.
In an embodiment, a positioning and buckling device is disposed between the secondary separation cyclone 242 and the separation filter screen 243. The positioning and buckling device includes a positioning and clamping block 244 and a positioning and clamping groove 245. The positioning and clamping block 244 and the separation filter screen 243 are disposed on the secondary separation cyclone 242 and the separation filter screen 243 respectively to achieve a position-limiting fit of the secondary separation cyclone 242 and the separation filter screen 243. The design of the positioning and buckling device ensures that the user may simply and conveniently mount the secondary separation cyclone 242 and the separation filter screen 243 again respectively after detaching and cleaning the secondary separation cyclone 242 and the separation filter screen 243 of the dust barrel, without incomplete sealing caused by loose buckling or improper mounting.
Optionally, the sealing end cover 246 is provided with a positioning block 247. The positioning block 247 is fitted with the positioning and buckling device, which can also ensure that the user may simply and conveniently mount the sealing end cover 246 again after detaching and cleaning the sealing end cover 246, without incomplete sealing caused by loose buckling or improper mounting.
In an embodiment, as shown in
The mounting body 102 is connected to the base 101, and an air inlet conduit 80 is provided within the mounting body 102. As shown in
Optionally, the dust barrel 20 is detachably disposed on the mounting body 102. The fan assembly 40 is disposed on the mounting body 102.
The cleaning robot enters the base 101 from a front end of the base 101, and the mounting body 102 is disposed at a rear end of the base 101, so that the cleaning robot may not collide with the mounting body 102 during movement.
In some embodiments, the mounting body 102 and the base 101 may be of an integrated structure. Here, the integrated structure may be integrated molding, or may also refer to connecting and fixing two separate components to form an integral structure.
In some embodiments, the mounting body 102 is detachably connected to the base 101. That is, the mounting body 102 may be separated from the base 101 before use, so as to facilitate transportation and storage, etc., and the mounting body 102 is connected to the base 101 by means of connection in the related art such as a fastener or engagement during use.
Optionally, the air inlet conduit 80 may be connected onto the base 101, that is, the air inlet conduit 80 is connected onto the base 101 after the mounting body 102 is separated from the base 101. Alternatively, the air inlet conduit 80 may be connected onto the mounting body 102, that is, the air inlet conduit 80 is connected onto the mounting body 102 after the mounting body 102 is separated from the base 101. Alternatively, the air inlet conduit 80 may be separated from the base 101 and the mounting body 102. In some embodiments, it is not excluded that the air inlet conduit 80 is integrated onto the base 101 or the mounting body 102.
In an embodiment, as shown in
The air inlet end 31 of the first filtering assembly 30 is communicated with the airflow outlet end 22 of the dust barrel 20, so as to filter the airflows discharged through the dust barrel 20.
An air outlet end 32 of the first filtering assembly 30 is communicated with the air inlet 41 of the fan assembly 40. When the cleaning robot moves to the body 10 and the garbage inlet of the cleaning robot is communicated with the dust inlet 111 of the dust inlet channel 11, the fan assembly 40 runs and generates a negative pressure at this time, which can suck the dust within the dust box into the dust barrel 20 for collection, and the airflows are filtered through the first filtering assembly 30 before entering the fan assembly 40, thereby avoiding the dust from entering the interior of the fan assembly 40. Finally, the airflows are discharged from the fan assembly 40, such that the dust within the dust box of the cleaning robot is recycled into the dust barrel 20. Therefore, automated processing may be enabled for the whole dust cleaning process.
The first filtering assembly 30 is located above the fan assembly 40. That is, the airflows discharged from the dust barrel 20 need to be filtered through the first filtering assembly 30 first, and then flow into the air inlet 41 of the fan assembly 40 from the bottom of the first filtering assembly 30, so that the distribution of a flowing path of the airflows is more reasonable, and it can be ensured that the distribution of components is more reasonable, thereby utilizing a height space effectively.
The first filtering assembly 30 may be directly disposed on the body 10, or may also be directly disposed on the fan assembly 40.
In some embodiments, the first filtering assembly 30 is disposed on the mounting body 102. That is, after the mounting body 102 is separated from the base 101, the dust barrel 20, the first filtering assembly 30, and the fan assembly 40 may be all separated from the base 101 along with the mounting body 102.
Optionally, the first filtering assembly 30 is detachably disposed on the mounting body 102, or may also be fixed onto the mounting body 102.
In an embodiment, as shown in
A first detection member is disposed between the dust barrel 20 and the first mounting portion 13 and used for detecting whether the dust barrel 20 and the first mounting portion 13 are mounted in position. For example, when the dust barrel 20 and the first mounting portion 13 are mounted in position, the first detection member may send a first signal.
A second detection member is disposed between the first filtering assembly 30 and the second mounting portion 14 and used for detecting whether the first filtering assembly 30 and the second mounting portion 14 are mounted in position. For example, when the first filtering assembly 30 and the second mounting portion 14 are mounted in position, the second detection member may send a second signal.
The dust collecting pile further includes a control portion that is in signal connection with the first detection member or the second detection member. The control portion is in signal connection with the fan assembly 40, and the first detection member is in signal connection with the second detection member, so that the control portion cannot start the fan assembly 40 when at least one of the dust barrel 20 or the first filtering assembly 30 is not mounted in position. That is, the first detection member and the second detection member are in a series relationship. Therefore, the control portion can start the fan assembly 40 only when the first detection member sends the first signal and the second detection member sends the second signal. For example, the first detection member may be connected to a control end of the second detection member, while a signal transmitting end of the second detection member is connected to the control portion. If the control end of the second detection member cannot receive the first signal sent by the first detection member, the second detection member cannot send a starting signal (for example, the second signal) to the control portion even if the first filtering assembly 30 and the second mounting portion 14 are mounted in position.
In this embodiment, in-position detection of the dust barrel 20 and in-position detection of the first filtering assembly 30 with an OR relationship can be implemented by connecting the first detection member with the second detection member in series. That is, if the dust barrel 20 is not in position, or the first filtering assembly 30 is not in position, or both of them are not in position, the control portion may recognize them as being not in position (that is, the control portion determines that the dust collecting pile is not mounted in position), so that electrical connection components and recognition components may be reduced.
In an embodiment, the dust barrel 20 is detachably connected to the first mounting portion 13, so as to facilitate the cleaning and replacing of the dust barrel 20.
It should be noted that the dust barrel 20 and the first mounting portion 13 may be engaged, for example, through a fit between a bump and a slide way, or a mounting groove may be formed in the first mounting portion 13, while at least a part of the dust barrel 20 is located within the mounting groove, which is not defined here and may be selected according to actual needs as long as it is ensured that they are easy to mount and will not fall off arbitrarily.
In an embodiment, the first filtering assembly 30 is detachably connected to the second mounting portion 14, so as to facilitate the cleaning and replacing of the first filtering assembly 30, thereby improving the filtering capability of the first filtering assembly 30.
It should be noted that the first filtering assembly 30 and the second mounting portion 14 may be engaged, for example, through a fit between a bump and a slide way, or a mounting groove may be formed in the second mounting portion 14, while at least a part of the first filtering assembly 30 is located within the mounting groove, which is not defined here and may be selected according to actual needs as long as it is ensured that they are easy to mount and will not fall off arbitrarily. In this embodiment, the second mounting portion 14 has a mounting cavity, while the first filtering assembly 30 is located within the mounting cavity. In addition, a sealed connection is formed between the upper portion of the first filtering assembly 30 and the body 10, while a second channel 18 is disposed on the body 10. The second channel 18 communicates the air outlet end 32 of the first filtering assembly 30 with the air inlet 41 of the fan assembly 40, so as to ensure that the airflows discharged through the first filtering assembly 30 only enter the air inlet 41 of the fan assembly 40 through the second channel 18.
In an embodiment, the dust barrel 20 includes a dust bag 23 or the cyclone separator 24. The dust barrel 20 may collect garbage through the dust bag 23 or through the cyclone separator 24. The dust bag may be a paper bag or cloth bag with good air permeable and dust proof effects, as long as it is easy to replace.
Optionally, the dust barrel 20 mounted with the cyclone separator 24 may be mounted with the dust bag 23 through a dust bag transition device 25 to meet different requirements of the user. That is, the dust bag transition device 25 is similar to a support and mainly used to mount the dust bag 23 onto the dust barrel 20 and has a specific structure similar to a component of the cyclone separator 24 that is connected to the dust barrel 20, which is not defined here as long as it can be connected to the dust barrel 20, actually like a component disposed by imitating a connection structure of the cyclone separator 24. Optionally, the dust bag 23 may be provided with a transition portion 231 for being connected to the dust bag transition device 25, which is specifically as shown in
Optionally, as shown in
Optionally, as shown in
In an embodiment, the first mounting portion 13 and the second mounting portion 14 are spaced apart from each other, so that the dust barrel 20 or the first filtering assembly 30 can be mounted on the body 10 first, or the dust barrel 20 and the first filtering assembly 30 can be mounted on the body 10 simultaneously. That is, the dust barrel 20 and the first filtering assembly 30 are mounted without a limitation by a mounting sequence, and may be mounted and detached arbitrarily as required, without interference between the components, thereby simplifying the structures and facilitating the mounting.
The first mounting portion 13 and the second mounting portion 14 may be distributed on two sides of the base 101 sequentially. In addition, two structures similar in appearance are formed above the base 101 after the dust barrel 20 is mounted to the first mounting portion 13, while the first filtering assembly 30 is mounted inside the second mounting portion 14.
In an embodiment, the first detection member is a contact detection element or a non-contact detection element, and the second detection member is a contact detection element or a non-contact detection element.
Specifically, the first detection member may include a contact switch sensing element and a contact switch fitting element, and the second detection member may include a non-contact sensing element and a non-contact sensing and fitting element. The first mounting portion 13 is provided with a contact switch sensing element, and the dust barrel 20 is provided with a contact switch fitting element. The contact switch sensing element may be fitted with the contact switch fitting element when the dust barrel 20 is mounted to the first mounting portion 13, such that the contact switch sensing and fitting element can sense the contact switch sensing element. The second mounting portion 14 is provided with a non-contact sensing element, and the first filtering assembly 30 is provided with a non-contact sensing and fitting element. The non-contact sensing and fitting element may be fitted with the non-contact sensing element when the first filtering assembly 30 is mounted to the second mounting portion 14, such that the non-contact sensing and fitting element can sense the non-contact sensing element.
It should be noted that the contact detection elements may be contact sensors in the related art, such as pressure sensors and switch elements, and the non-contact detection elements may be non-contact sensors in the related art, such as laser sensors and inductive proximity sensors.

In some embodiments, the switch 131 is disposed on the second mounting portion 14, and the detection button 132 is disposed to face the switch 131, so that the detection button 132 presses the switch 131 to be in the closed state when the first filtering assembly 30 and the second mounting portion 14 are mounted in position. That is, after the first filtering assembly 30 is mounted in position, the switch 131 is in the closed state, so as to output the corresponding signals.

As shown in conjunction with
In an embodiment, the dust containing member 33 includes dust containing cotton. After entering the first filtering assembly 30, the airflows may pass through the dust containing cotton first. The dust containing cotton cannot intercept all the dust within specifications, but can intercept some of larger particles to reduce the risk that the filtering portion 34 is blocked, thereby prolonging the service life of the whole first filtering assembly 30.
Optionally, the dust containing member 33 includes sponge. The filtering portion 34 may be a filter, which may include filtering cotton.
In an embodiment, as shown in
In an embodiment, the filtering portion 34 encloses the dust containing member 33, so that the filtering portion 34 can not only implement the fixation of the dust containing member 33, but also allow the airflows flowing out of the dust containing portion 33 to be discharged directly through the filtering portion 34, thereby ensuring the filtering effect and simplify the structure.
In an embodiment, the dust containing member 33 and the filtering portion 34 are disposed on the top cover 35, so that the dust containing member 33 and the filtering portion 34 are fixed on the top cover 35.
Specifically, the top cover 35 of the first filtering assembly 30 may be connected to the body 10, so as to dispose the first filtering assembly 30 on the body 10.
Optionally, at least one of the dust containing member 33 or the filtering portion 34 may be directly fixed on the top cover 35, that is, the dust containing member 33 may be connected to the top cover 35, while the filtering portion 34 may enclose the dust containing member 33. That is, the filtering portion 34 is connected to the dust containing member 33, and may not be connected to the top cover 35 directly.
Optionally, the filtering portion 34 is connected to the top cover 35 to form an accommodation space between the filtering portion 34 and the top cover 35, and the dust containing member 33 is located within the accommodation space. That is, the dust containing member 33 is fixed within the accommodation spaced formed between the filtering portion 34 and the top cover 35.
In an embodiment, the filtering portion 34 is detachably disposed on the top cover 35, so as to facilitate replacing the filtering portion 34 and the dust containing member 33. The filtering portion 34 and the top cover 35 may be engaged, adhered or connected by a fastener, which is not defined here as long as they are easy to be detached and mounted.
In an embodiment, an area of the top cover 35 covering the dusting containing member 33 is less than that of the filtering portion 34 covering the dust containing member 33, so that the air inlet end 31 of the dust containing member 33 is smaller than the air outlet end 32, thereby ensuring that the airflows flow out rapidly, and the dust containing member 33 implements absorption of the dust to the maximum extent.
In an embodiment, as shown in

The arrangement of the flexible member 45 may avoid the direct contact between the fan 44 and the housing 43, so as to avoid large noise. In addition, since the fan 44 is fixed within the housing 43 by the flexible member 45, the housing 43 may be enabled to adapt to the fans 44 of different types as long as the flexible member 45 is replaced, so as to improve the generality of the housing 43.
Specifically, a mounting cavity is formed in the body 10, both the fan assembly 40 and the first filtering assembly 30 are disposed within the mounting cavity, and a partition plate is disposed between the fan assembly 40 and the first filtering assembly 30. A second channel 18 is disposed on the partition plate. The second channel 18 communicates the air outlet end 32 of the first filtering assembly 30 with the air inlet 41 of the fan assembly 40, so as to ensure that the airflows discharged through the first filtering assembly 30 only enter the air inlet 41 of the fan assembly 40 through the second channel 18, which is specifically as shown in
In an embodiment, as shown in
In some embodiments, the second housing member 432 is connected to the first housing member 431 in a sealed manner, and the second housing member 432 may be connected to the first housing member 431 through a plurality of fasteners.

In an embodiment, a part of the second flexible portion 452 is clamped between the first housing member 431 and the second housing member 432 to seal a gap between the first housing member 431 and the second housing member 432, so as to prevent the first housing member 431 and the second housing member 432 from being sealed by using other sealing members, which is simple in structure and may reduce mounting steps.
In an embodiment, the first flexible portion 451 is a rubber mat, and the second flexible portion 452 is a rubber sleeve. The rubber mat is supported between the fan 44 and the first housing member 431, while the rubber sleeve is sleeved over an upper portion of the fan 44, so as to protect the fan 44.
In an embodiment, the second housing member 432 is provided with an airflow through hole 433, the airflow through hole 433 is communicated with the air inlet 41 of the fan 44, and there is a clearance between the first housing member 431 and the fan 44. An air discharging channel 46 is formed among the first flexible portion 451, the second flexible portion 452, the first housing member 431, and the fan 44, and the air discharging channel 46 is communicated with the air outlet 42 of the fan 44. The airflows discharged from the first filtering assembly 30 enter the air inlet 41 of the fan 44 through the airflow through hole 433, discharged into the air discharging channel 46 through the air outlet 42 of the fan 44, and finally discharged out from the air discharging channel 46, so as to achieve the circular flowing of the airflows.
As shown in
In an embodiment, the fan assembly 40 further includes an air discharging hole 434. The air discharging hole 434 is communicated with the air discharging channel 46, so as to discharge the airflows within the air discharging channel 46 out of the fan assembly 40.
Optionally, the air discharging hole 434 is formed in the housing 43, so as to discharge the airflows within the air discharging channel 46. Specifically, the air discharging hole 434 may be formed in the first housing member 431, that is, the airflows within the air discharging channel 46 may be discharged from the fan assembly 40 without punching a hole in the second flexible portion 452. The air discharging hole 434 may also be formed in the second housing member 432, that is, a hole may be formed in the second flexible portion 452 to communicate the air discharging hole 434 with the air discharging channel 46. Specific positions of the air discharging hole 434 may not be defined, as long as it is ensured that the airflows can be discharged out of the air discharging channel 46.
In an embodiment, as shown in
Optionally, the silencer 47 may be disposed inside the housing 43, the air discharging channel 46 is communicated with the inlet of the silencer 47, and the outlet of the silencer 47 is communicated with the air discharging hole 434, so that the airflows pass through the silencer 47 first and are then discharged out of the housing 43.
Optionally, the silencer 47 may be disposed outside the housing 43, the air discharging channel 46 is communicated with the air discharging hole 434, and the air discharging hole 434 is communicated with the inlet of the silencer 47, so that the airflows are discharged out of the housing 43 first, and then silenced by the silencer 47.
In an embodiment, the air discharging channel 46 is disposed around a circumferential outer surface of the fan 44, and the length of the air discharging channel 46 extending along the circumferential outer surface of the fan 44 is greater than that of the air discharging hole 434 extending along the circumferential outer surface of the fan 44. That is, the airflows discharged from the fan 44 are only discharged out of the housing 43 from a relatively fixed position, so that the airflows may rotate within the air discharging channel 46 for nearly one revolution, and are then discharged from the air discharging hole 434. As such, noise may be reduced by extending an airflow path.
Specifically, air outlets 42 may be formed on the circumferential outer surface of the fan 44 by nearly one revolution, and the air discharging channel 46 also forms a surrounding space for nearly one revolution at this point, so that airflows from the air outlets 42 at respective positions can be directly discharged into the air discharging channel 46, and at this point, the air discharging hole 434 on the housing 43 may be located in a circumferential direction of the housing 43. The air discharging hole 434 on the housing 43 may also be formed in the top of the housing 43, and at this point, the air discharging channel 46 may be communicated with the air discharging hole 434 through a pipeline, so as to ensure that the airflows discharged from the air discharging channel 46 need to be rotated to a relatively fixed position for discharge, thereby reducing noise by increasing the airflow paths.
In an embodiment, as shown in
Since the wind pressure detection device needs an electrical connection, in order to reduce the impact of a change in air pressure within the body 10 on the service life of electrical connection devices, the wind pressure detection device is mounted outside a wind path pipeline of the whole dust collecting pile. Therefore, it is necessary to connect the wind path pipeline with the wind pressure detection device together by the wind pressure measuring hole 48 and the wind pressure pipeline 49, so as to facilitate detecting the wind pressure within the wind path by the wind pressure detection device.
The wind pressure detection device may be mounted on a circuit board of the dust collecting pile, thereby achieving the integration of an electronic device and facilitating the production of products.
Optionally, the wind pressure measuring hole 48 is formed between the fan assembly 40 and the first filtering assembly 30. The fan 44 may first draw air within the first filtering assembly 30 out to form a topical negative pressure after the fan 44 starts, and then form an airflow due to an air pressure, thereby completing the whole air-drawing action. Therefore, the highest measurement accuracy and measurement efficiency can be achieved by forming the wind pressure measuring hole 48 between the fan assembly 40 and the first filtering assembly 30.
Optionally, since the first filtering assembly 30 is of a tubular structure and may be in direct contact with the wind pressure measuring hole 48 during mounting, a frustum-shaped protrusion is then disposed outside the air inlet of the fan assembly 40 and the wind pressure measuring hole 48 may be formed at the frustum-shaped protrusion, so as to avoid the wind pressure measuring hole 48 from being stuck by the first filtering assembly 30 to affect a measuring effect.
In an embodiment, as shown in
In some embodiments, the second filtering assembly 50 may be of a conventional filtering structure, that is, may include a filter screen, so as to achieve secondary filtering of the airflows and ensure that the discharged airflows are clean. For example, the second filtering assembly 50 may be of an annular structure, namely, a circumferential closed structure, so as to be disposed around the first filtering assembly 30. The airflows enter the fan assembly 40 from the first filtering assembly 30, that is, flow from top to bottom; and then, the airflows enter the second filtering assembly 50 from the fan assembly 40, that is, flow from bottom to top.
In some embodiments, as shown in
Optionally, the dust collecting pile further includes an air inlet conduit 80. One end of the air inlet conduit 80 is communicated with the dust inlet channel 11, and the other end of the air inlet conduit 80 is communicated with the dust inlet end 21. The opening 53 can evade the air inlet conduit 80.
Optionally, the body 10 further includes a communication pipeline 17. Two ends of the communication pipeline 17 are respectively communicated with the air inlet end 31 of the first filtering assembly 30 and the airflow outlet end 22 of the dust barrel 20, and the opening 53 can evade the communication pipeline 17, so as to ensure the compactness of the structure.

That is, the frame 54 is adapted to the filter screen 55, so that the opening 53 is formed in the second filtering assembly 50. The overall structure of the second filtering assembly 50 may be similar to a C-shaped structure or may be a U-shaped structure, which is not defined here and may be determined according to the specific structure form of the second mounting portion 14, so as to ensure the reasonable distribution of the components.
The second filtering assembly 50 in this embodiment includes the frame 54 and the filter screen 55, and the evasion groove 56 is formed in the filter screen 55, so that the second filtering assembly 50 can be enabled to evade other internal structures, which can not only reduce the size of the filter screen 55, but also ensure reasonable arrangement of other components, thereby improving the usage performance of the second filtering assembly 50.
In an embodiment, the filter screen 55 is an arc-shaped filter screen. That is, on the premise of ensuring an effective filtering area, the structure of the filter screen 55 may be reduced to the maximum extent, so as to be adapted to a circumferential outer surface of the second mounting portion 14.
In an embodiment, an area of the third opening 563 is less than that of the filter screen 55, that is, it is ensured that the filter screen 55 has a sufficient filtering area.

In an embodiment, as shown in
As shown in
When the dust in the dust box enters the dust inlet channel 11, it is necessary to ensure that the dust inlet channel 11 forms a negative pressure environment, so that the shielding member 90 closes the liquid outlet hole 12 to ensure that the dust inlet channel 11 is not communicated with the outside. In addition, when the dust in the dust box stops entering the dust inlet channel 11, the shielding member 90 may be opened, so that the dust inlet channel 11 is communicated with the outside. Liquid entering the dust inlet channel 11 may be discharged out of the dust inlet channel 11 through the liquid outlet hole 12, so as to ensure, to the maximum extent, that the dust inlet channel 11 is dry inside.
It should be noted that “the outside” described above may be interpreted as an external environment space, or may also be other space independent from the dust inlet channel 11. For example, a liquid collector may be provided to allow the liquid within the dust inlet channel 11 to flow into the liquid collector, and a space formed by the liquid collector may also be understood as the outside at this point.
In some embodiments, the shielding member 90 is movably disposed on the body 10, and may be driven by a driving mechanism to move, so as to achieve closing and releasing of the liquid outlet hole 12. Specifically, the driving mechanism may be an air cylinder, an oil cylinder or an electric cylinder, and a telescopic rod of the driving mechanism may drive the shielding member 90 to move relative to the liquid outlet hole 12, thereby achieving the closing and releasing of the liquid outlet hole 12. Alternatively, the driving mechanism may include a motor, and the shielding member 90 is driven by the motor to rotate relative to the body 10, thereby achieving the closing and releasing of the liquid outlet hole 12.
It should be noted that the fan assembly 40 starts to clean the dust within the dust box at the beginning of running, and the shielding member 90 can rotate from the open position to the sealed position. Specifically, the control portion of the dust collecting pile may control the above driving mechanism to drive the shielding member 90 to move from the open position to the sealed position prior to controlling the fan assembly 40 to run, or the control portion may control the fan assembly 40 and the above driving mechanism to run simultaneously. In addition, when the fan assembly 40 stops running, the cleaning of the dust within the dust box is stopped, and the shielding member 90 can rotate from the sealed position to the open position. Specifically, the control portion of the dust collecting pile may control the above driving mechanism to drive the shielding member 90 to move from the sealed position to the open position after controlling the fan assembly 40 to stop running, or the control portion may control the above driving mechanism to run while controlling the fan assembly 40 to stop running.
In some embodiments, the shielding member 90 may be connected onto the body 10, and the movement of the shielding member 90 does not depend on the driving mechanism. The shielding member 90 can rotate from the open position to the sealed position under the driving of the fan assembly 40. That is, when the fan assembly 40 is running, depending on the negative pressure generated by the fan assembly 40, the shielding member 90 may be driven to move from the open position to the sealed position. In addition, when the fan assembly 40 stops running, the shielding member 90 can rotate from the sealed position to the open position under the action of gravity.
Optionally, the shielding member 90 may be disposed on a plate body, and this plate body is rotatably disposed on the body 10, so as to ensure that the shielding member 90 rotates from the sealed position to the open position under the action of gravity.
In an embodiment, the liquid outlet hole 12 is communicated with one side of the dust inlet channel 11 close to the dust barrel 20. That is, when the fan assembly 40 is running, the liquid may flow from the dust inlet 111 to the dust barrel 20 along the dust inlet channel 11. Therefore, after the fan assembly 40 stops running, most of the liquid is gathered at one side close to the dust barrel 20. At this point, the liquid can flow out conveniently from the liquid outlet hole 12 by opening the liquid outlet hole 12.
In an embodiment, as shown in
Optionally, when the shielding member 90 is in the sealed position, the shielding member 90 may be in a clearance fit with a side wall of the sealing groove 19 and may stop against the liquid outlet hole 12 reliably, so as to achieve sealing of the liquid outlet hole 12.
Optionally, when the shielding member 90 is in the sealed position, the shielding member 90 may be in an interference fit with the side wall of the sealing groove 19. That is, the shielding member 90 seals the sealing groove 19, so as to enable the sealing of the liquid outlet hole 12.
It should be noted that the sealing groove 19 may be formed on one side of the liquid outlet hole 12 close to the dust inlet channel 11. That is, the sealing groove 19 is located within the dust inlet channel 11. At this point, the shielding member 90 may be driven by the driving mechanism to move.
Alternatively, the sealing groove 19 may be disposed on one side of the liquid outlet hole 12 away from the dust inlet channel 11. That is, the sealing groove 19 is located outside the dust inlet channel 11. At this point, the shielding member 90 may be driven by the fan assembly 40 to move, and may be disengaged from the sealing groove 19 under the action of gravity.
In an embodiment, the shielding member 90 is disposed on a plate body. This plate body allows the shielding member 90 to be disengaged from the sealing groove 19 under the action of gravity when the fan assembly 40 does not work. The plate body may be driven to rotate only when the fan assembly 40 works, so that the shielding member 90 is located within the sealing groove 19, so as to achieve the sealing of the liquid outlet hole 12.
In an embodiment, the shielding member 90 is rotatably disposed on the body 10, so that the shielding member 90 can be switched between the sealed position and the open position. The shielding member 90 may be rotated by the driving mechanism relative to the body 10, so as to seal or release the liquid outlet hole 12. Alternatively, the shielding member 90 may be enabled to rotate under the action of the fan assembly 40, and may rotate from the sealed position to the open position under the action of gravity.
In an embodiment, the shielding member 90 is disposed on one side of the body 10 away from the dust inlet channel 11. That is, the shielding member 90 may rotate from the sealed position to the open position under the action of gravity.
In an embodiment, at least a part of the shielding member 90 is a flexible member, which not only has strong structure stability, but also can better implement the sealing of the liquid outlet hole 12. Optionally, at least a part of the shielding member 90 is rubber, and the shielding member 90 may be a soft rubber sheet. After the fan assembly 40 runs and generates a negative pressure to suck up the soft rubber sheet, the liquid outlet hole 12 is blocked to achieve a sealing effect. When the fan assembly 40 does not work, the soft rubber sheet returns to its original position, and the liquid may flow out of the dust inlet channel 11 through the liquid outlet hole 12, so as to avoid the retention of a large amount of liquid within the dust inlet channel 11.
In some embodiments, the liquid outlet hole 12 may be a circular hole, a triangular hole or a rectangular hole. Of course, the liquid outlet hole 12 may also be an irregularly-shaped hole, which is not defined here. In addition, a specific structural shape of the sealing groove 19 for accommodating the shielding member 90 may also be circular, triangular or rectangular. Of course, the sealing groove 19 may also be an irregularly-shaped groove.
In an embodiment, a plurality of liquid outlet holes 12 is provided to increase a rate at which the liquid flows out and ensure that the liquid within the dust inlet channel 11 flows out reliably.
Optionally, at least one shielding member 90 is provided, where one shielding member 90 can shield a plurality of liquid outlet holes 12, so as to simplify the structure.
Optionally, a plurality of shielding members 90 is disposed in a one-to-one correspondence to the plurality of liquid outlet holes 12 to ensure that the respective shielding members 90 seal the respective liquid outlet holes 12 independently, thereby increasing the reliability of sealing.

In an embodiment, the upper side of the spoiler 60 is connected to at least one of the body 10 or the second filtering assembly 50 to avoid a top end of the spoiler channel 61 from being directly communicated with that of the air outlet channel 62, that is, to prevent the airflows from flowing from the top end of the spoiler channel 61 into the air outlet channel 62.
Optionally, the spoiler 60 may be connected onto the body 10, so that a sealed connection is formed between the top end of the spoiler 60 and the body 10.
Optionally, as shown in conjunction with
In an embodiment, the bottom end of the spoiler 60 is disposed in a suspended manner, so that the bottom end of the spoiler channel 61 is communicated with that of the air outlet channel 62. That is, both the second filtering assembly 50 and the body 10 may not be in contact with the bottom end of the spoiler 60, so that the airflows enter the air outlet channel 62 along the bottom end of the spoiler 60.
Optionally, the bottom end of the spoiler 60 may be lower than that of the air outlet surface 52, as long as it is ensured that a sealed connection is not formed between the bottom end of the spoiler 60 and the body 10.
Optionally, the bottom end of the spoiler 60 is higher than that of the air outlet surface 52. That is, a part of the airflows discharged from the air outlet surface 52 may not be stopped by the spoiler 60 as well.
In an embodiment, as shown in
In some embodiments, the communication channel 65 is a through hole, which is located in a middle portion of the spoiler 60. That is, the spoiler channel 61 is also communicated with the air outlet channel 62 through the through hole.
In some embodiments, the communication channel 65 is a notch, which recesses upward from the bottom end of the spoiler 60. That is, it can be understood that an opening is formed in the spoiler 60 to release the airflows directly.
In an embodiment, a plurality of communication channels 65 is provided, so as to ensure that the airflows at different positions can enter the air outlet channel 62 directly through the communication channels 65.
In an embodiment, the air outlet surface 52 includes a curved surface, the spoiler 60 includes an arc-shaped plate disposed to face the curved surface, the plurality of communication channels 65 is disposed along a circumferential direction of the arc-shaped plate at intervals, and a shape of the spoiler 60 is adapted to the air outlet surface 52, which may not only ensure reliable filtering, but also enable the structure to have a reasonable layout.
In an embodiment, as shown in
Optionally, the through hole 71 of the air outlet plate 70 may be communicated with the air outlet surface 52 of the second filtering assembly 50 directly. That is, the spoiler 60 may be removed, and the airflows out of the air outlet surface 52 of the second filtering assembly 50 may be discharged through the through hole 71 of the air outlet plate 70 directly.
As shown in
In an embodiment, both a plurality of first charging contact tabs 103 and a plurality of second charging contact tabs are disposed in pairs.
The cleaning robot needs to move onto the body 10 for subsequent dust box cleaning or charging.
Specifically, the cleaning robot may move along the body 10, that is, the cleaning robot may perform a pile climbing motion. The pile climbing motion may be understood as follows: when a distance between the cleaning robot and the body 10 is less than a certain threshold, for example, when the cleaning robot has reached the vicinity of the body 10, the cleaning robot may move in a certain direction more apparent.
