The cleaning device may be, but is not limited to, an automatic floor scrubber, an automatic mopping and sweeping all-in-one machine, etc. Taking an automatic scrubber as an example, the automatic scrubber may also include, but is not limited to, a main body 1, a traveling mechanism, a cleaning fluid supply system, a controller, a sensing portion and a dirt recovery pipeline. It should be noted that the cleaning device may also include other components not shown, or may only include some of the above components or assemblies, which is not strictly limited in the embodiments of the present disclosure
The main body 1 may be provided with a first storage apparatus 101 and a second storage apparatus 102. The first storage apparatus 101 and the second storage apparatus 102 are arranged one above the other, so that the width of the cleaning device can be reduced, which saves the occupied space of the cleaning device in the horizontal direction and facilitates storage of the cleaning device. Moreover, the first storage apparatus 101 and the second storage apparatus 102 are coaxially arranged, that is, the central axis of the first storage apparatus 101 and the central axis of the second storage apparatus 102 coincide with each other, so that the cleaning device is prevented from toppling over due to its unstable center of gravity The first storage apparatus 101 and the second storage apparatus 102 may be integrally formed by a material, for example, plastic, so as to improve the elasticity, toughness, corrosion resistance and anti-collision performance of the main body 1 and reduce the weight of the main body 1. A plurality of grooves, recesses 39, clamping positions or similar structures may be pre-formed on the peripheral walls of the first storage apparatus 101 and the second storage apparatus 102, and are used for mounting the cleaning fluid supply system, the dirt recovery pipeline, the traveling mechanism, the sensing portion and the controller. Meanwhile, it is unnecessary to additionally manufacture a housing and other members, so that the production process can be simplified. In some embodiments, the first storage apparatus 101 may be used as a cleaning fluid storage apparatus, and the second storage apparatus 102 may be used as a dirt storage apparatus. In other embodiments, the first storage apparatus 101 may be used as a dirt storage apparatus, and the second storage apparatus 102 may be used as a cleaning fluid storage apparatus. Further, in the case that clean water and a detergent are mixed together, the cleaning fluid storage apparatus may also be divided into two compartments, with the volume of one compartment much larger than that of the other, so that the larger compartment stores clean water and the smaller compartment stores the detergent. Moreover, when the floor scrubber is configured to clean a large place, the size of the main body 1 may be increased to improve the volumes of the cleaning fluid storage apparatus and the dirt storage apparatus, so that the cleaning fluid storage apparatus has sufficient cleaning fluid to meet cleaning requirements. The cleaning fluid may be a cleaning solution or a mixed solution of clean water and the detergent, and dirt includes stains on a surface to be cleaned and a soiling liquid formed after cleaning of the surface to be cleaned.
The traveling mechanism includes a plurality of groups of wheels arranged at the lower portion of the main body 1 and a driving mechanism, the two wheels of each group are respectively located on two opposite sides of the main body 1, the driving mechanism is arranged in a robot body, and drives the wheels to drive the main body 1 to run for cleaning.
The sensing portion is configured to sense range information, speed information, posture information and the like of a self-moving device. According to the collected information fed back by the sensing portion, the controller may control the self-moving cleaning device to carry out autonomous travelling cleaning. Specifically, the sensing portion includes a variety of different sensors to collect different information of the self-moving device, so as to fully perceive the state and the ambient environment of the self-moving device.
The controller is arranged on a main circuit board in the body, and includes a memory (such as a hard disk, a flash memory and a random access memory), a processor (such as a central processing unit and an application processor), and the like. The processor draws a real-time map of an environment where the self-moving cleaning device is located according to object information fed back by the sensing portion, so as to plan the most efficient and reasonable cleaning path and cleaning mode to greatly improve the cleaning efficiency of the self-moving cleaning device. In addition, according to the range information, speed information, posture information and the like fed back by the sensing portion, the current working state of the self-moving cleaning device may be comprehensively determined, so that specific next-action strategies can be given according to different situations, and corresponding control instructions may be sent to the self-moving cleaning device.
The cleaning fluid supply system includes a cleaning assembly 12, a cleaning fluid output pipeline, a nozzle arranged in a cleaning head housing and configured to provide the cleaning fluid to the cleaning assembly 12, and a lifting and lowering assembly 11 configured to lift and lower the cleaning assembly 12. The dirt storage apparatus is communicated with the nozzle by means of the cleaning fluid output pipeline, and the cleaning fluid output pipeline is also provided with necessary components, for example, a pump, so that the cleaning fluid may be delivered to the nozzle in time and in sufficient quantity. During a cleaning operation, the lifting and lowering assembly 11 lowers the cleaning assembly 12, so that the cleaning assembly 12 can be in contact with the surface to be cleaned, and then the cleaning fluid is delivered to the nozzle to be provided for the cleaning assembly 12, thereby realizing the cleaning operation. Upon completion of the cleaning operation, the lifting and lowering assembly 11 drives the cleaning assembly 12 to rise, so that the cleaning assembly 12 is kept a certain distance away from the surface to be cleaned, thereby reducing wear on the cleaning assembly 12 from the ground and prolonging the service life of the cleaning assembly 12.
As shown in
As shown in
In other embodiments, the nozzle may also be arranged on the outer side of the cleaning head housing and located on the front side of a suction port, so that the same effect of scrubbing the surface to be cleaned can also be achieved by directly wetting the surface to be cleaned on the front side of the suction port using the nozzle and brushing the wetted surface to be cleaned using a cleaning member.
As shown in
The first electronic assembly 4 includes, but is not limited to, a sensing portion and a peripheral circuit. The sensing portion may be an orientation sensor, such as an inertial measurement unit (IMU) sensor. The IMU sensor includes three single-axis accelerometers and three single-axis gyroscopes. The accelerometers detect an acceleration signal of the self-moving device in a three-dimensional space, and the gyroscopes detect an angular velocity signal in a three-dimensional space, so as to calculate the posture of the self-moving device. Moreover, the IMU sensor has an autonomous navigation ability free from environment, carrier maneuver and radio interference, and thus, can effectively improve the reliability, integrity and continuity of positioning and posture determination. Of course, the sensing portion may also be configured as other types of sensors, which is not strictly limited in this embodiment. The shape of the first accommodating chamber 3 may be set according to the arrangement of other components in the main body 1, and may be set into a regular shape, for example, a cuboid, or a special shape. The volume of the first accommodating chamber 3 is larger than that occupied by the first electronic assembly 4, thereby facilitating not only mounting of the first electronic assembly 4, but also heat dissipation of the first electronic assembly 4.
In this embodiment, as shown by arrows in
In the embodiment described above, as shown in
The supporting portion 5 may be of a structure capable of playing a role of supporting, such as a support frame and a support table, and the first electronic assembly 4 may be mounted on the supporting portion 5 by a conventional fixing means such as a bolt 43 and a rivet. In this embodiment, the specific structure of the supporting portion 5 or the fixing form of the first electronic assembly 4 is not strictly limited.
The supporting portion 5 may enable the first electronic assembly 4 to be at a higher position. In this way, when a small amount of liquid flows into the first accommodating chamber 3, the first electronic assembly 4 may not be immersed in water, which reduces the risk of the failure of the first electronic assembly 4 subjected to the damp due to immersion in the liquid, and prolonging the service life and improving the use safety of the cleaning device.
Specifically, as shown in

Further, as shown in
Further, the first shielding portion 7 is a waterproof board. The waterproof board may be made of a plastic material. The plastic material has the characteristics of corrosion resistance and light weight, which not only prolongs the service life of the first shielding portion 7, but also reduces the weight of the first shielding portion 7. The plastic material includes polyvinyl chloride, polyethylene, polypropylene, polystyrene, polycarbonate, etc.
Further, the first accommodating chamber 3 is located at the lower portion of the main body 1, so that the distance between the first opening 6 of the first accommodating chamber 3 and the bottom of the main body 1 is reduced. In this way, the distance between the first flow drainage channel inlet located around the first opening 6 and the bottom of the main body 1 is also reduced, which in turn reduces the overall length of the first flow drainage channel 8. Therefore, not only can the discharge time of the liquid be shortened, but also the forming process of the first flow drainage channel 8 can be simplified to facilitate manufacture of the first flow drainage channel 8.
In some embodiments, as shown in
The first accommodating chamber 3 is isolated from the cleaning fluid accommodating space, which means that the cleaning fluid in the cleaning fluid storage apparatus may not flow into the first accommodating chamber 3, i.e., under normal circumstances, the first accommodating chamber 3 and the space for accommodating the cleaning fluid are independent of each other and do not affect each other, that is, the cleaning fluid in the cleaning fluid storage device may not leak into the first accommodating chamber 3 under normal circumstances.
The first accommodating chamber 3 is arranged in the cleaning fluid storage apparatus, so that it is unnecessary to reserve a space on the main body 1 for an additional accommodating chamber, which enables the structure to be more compact and reduces the overall size of the main body 1. The through hole formed in the base plate 103 corresponding to the first flow drainage channel 8 allows the liquid in the first flow drainage channel 8 to be smoothly discharged to the outside of the main body 1.
Further, the supporting portion 5 and the base plate 103 are integrally formed, so that not only is a process of assembling the supporting portion 5 and the base plate 103 omitted, but also the manufacturing process can be simplified.
Further, as shown in
The second flow drainage channel 9 is isolated from the cleaning fluid accommodating space, which means that the cleaning fluid in the cleaning fluid storage apparatus may not flow into the second flow drainage channel 9. In other words, under normal circumstances, the second flow drainage channel 9 and the space accommodating the cleaning fluid are independent of each other and do not affect each other, that is, the cleaning fluid in the cleaning fluid storage apparatus may not leak into the flow drainage channel under normal circumstances.
The liquid flowing into the cleaning fluid storage apparatus through a seam and other gaps 27 may be discharged to the outside of the cleaning fluid storage apparatus by means of the second flow drainage channel 9, so that the accumulation amount of the liquid in the cleaning fluid storage apparatus is effectively reduced, and the overall waterproofness of the cleaning fluid storage apparatus is improved. The through hole formed in the base plate 103 corresponding to the second flow drainage channel 9 allows the liquid in the second flow drainage channel 8 to be smoothly discharged to the outside of the cleaning fluid storage apparatus.
In specific applications, in order to further improve the overall waterproofness of the cleaning device, waterproof structures may also be added to other parts of the cleaning device. The waterproof structures of other parts will be described in detail below.
In some possible embodiments, as shown in
A reference may be made to the foregoing embodiments for the specific structure of the cleaning device, which will not be repeated herein.
In this embodiment, the drawing and sucking portion 14 draws and sucks air in the dirt storage apparatus by means of the air suction pipeline 15, and then the drawn and sucked air is discharged to the outside of the cleaning device by means of the air exhaust pipeline 26, so that the drawn and sucked air is prevented from flowing into the cleaning device, and thus, water vapor in the drawn and sucked air is prevented from flowing into the cleaning device, which in turn reduces the risk of the failure of the electronic components in the cleaning device located in a humid environment and thus subjected to the damp, and prolongs the service life and improves the use safety of the cleaning device.
In the embodiment described above, as shown in
The first waterproof seal 17 may be made of plastic and other waterproof materials, and the plastic material includes polyvinyl chloride, polyethylene, polypropylene, polystyrene, polycarbonate, etc. The first waterproof seal 17 may be fixed to the peripheral wall of the air exhaust pipeline 26 by a conventional means of fixing. Exemplarily, the first waterproof seal 17 is a plastic sticker and is adhered to the peripheral wall of the air exhaust pipeline 26 by means of an adhesive on the sticker, which not only facilitates mounting of the waterproof seal, but also improves the stability of connection between the first waterproof seal 17 and the air exhaust pipeline 26, and reduces the risk that the first waterproof seal 17 falls off the air exhaust pipeline 26.
In this embodiment, the first waterproof seal 17 is additionally provided on the peripheral wall of the air exhaust pipeline 26 for secondary waterproof sealing, so that when the air exhaust pipeline 26 cracks due to the impact of airflow and the like, water vapor carried by the airflow may be sealed in the air exhaust pipeline 26 by means of the first waterproof seal 17 to avoid water vapor leakage, which can further improve the waterproof airtightness of the air exhaust pipeline 26 and prevent water vapor in the air exhaust pipeline 26 from flowing into the cleaning device.
Further, as shown in
The seam at the connection may be sealed by the first fastener 21, so that the airtightness of the connection is improved, and airflow is prevented from flowing into the cleaning device from the seam at the connection, that is, water vapor carried by the airflow is prevented from entering the inside of the cleaning device through the seam at the connection. Moreover, the connection is improved in connection stability, and thus may not be disconnected due to the impact of the airflow. The first fastener 21 may be a hoop or may be of a strappable linear structure, which is not strictly limited in this embodiment.
In some possible embodiments, as shown in
The package 24 may seal some seams or recesses 39 formed in the first storage apparatus 101 during the process or assembling. so as to improve the overall airtightness of the main body 1 and prevent some external fluids (for example, water splashed on the main body 1 during cleaning) from flowing into the main body 1 through the seams. In addition, the package 24 may also be provided with a sensing portion, which solves the problem that the main body 1 formed by the rotational molding process cannot be directly provided with sensing components, and facilitates implementation of intelligence and automation of the self-moving cleaning device. The package 24 may be made of, for example, a plastic material, and are integrally formed. The plastic material has the characteristics of excellent elasticity, high toughness, light weight, excellent chemical stability, vibration resistance, etc., and thus can meet the use requirements of mounting of members. The plastic material includes polyvinyl chloride, polyethylene, polypropylene, polystyrene, polycarbonate, etc.
The second opening 16 is formed in the package 24 arranged at the air outlet 19 and corresponds to the air outlet 19, so as to avoid shielding of the air outlet 19 and enable the airflow in the air exhaust pipeline to be smoothly discharged to the outside of the cleaning device.
Further, as shown in FIG. S, a pipeline joint 18 is arranged at the second opening 16, the pipeline joint 18 passes through the air outlet 19, and extends toward the inside of the main body 1, and the air exhaust pipeline 26 is communicated with the pipeline joint 18.
Through the connection between the pipeline joint 18 and the air exhaust pipeline 26, the second opening 16 and the air exhaust pipeline may be stably connected to avoid misalignment of the second opening 16 with the air exhaust pipeline due to shaking of the cleaning device or the impact of the airflow, and this misalignment may cause the airflow in the air exhaust pipeline to flow into the cleaning device, and meanwhile introduce water vapor carried by the airflow into the cleaning device.
Further, as shown in
The seam at the connection may be sealed by the second fastener 23, so that the airtightness of the connection is improved, and airflow is prevented from flowing into the cleaning device from the seam at the connection, that is, water vapor carried by the airflow is prevented from entering the cleaning device through the seam at the connection. Moreover, the connection is improved in connection stability, and thus may not be disconnected due to the impact of the airflow. The second fastener 23 may be a hoop or may be of a strappable linear structure, which is not strictly limited in this embodiment.
Further, the pipeline joint 18 and the package 24 are integrally formed, so that a step of assembling the pipeline joint 18 and the package 24 is omitted, the assembling efficiency is improved, and the production process is simplified. Moreover, there is no seam between the pipeline joint 18 and the package 24, so that the airflow is prevented from flowing out from the connection between the pipeline joint 18 and the package 24, which improves the airtightness.
In other embodiments, as shown in
The drawing and sucking portion 14 is mounted in the second accommodating chamber 13 of the dirt storage apparatus, so that it is unnecessary to reserve a space on the main body 1 for accommodating the drawing and sucking portion 14, which can reduce the overall size of the main body 1, reduce the distance between the drawing and sucking portion 14 and the dirt storage apparatus, and further facilitate arrangement of the air suction pipeline 15 and the air exhaust pipeline 26. The third opening 20 and the fourth opening 22 are formed in the cavity wall of the second accommodation chamber 13 to avoid shielding of the air inlet end and the air outlet end of the drawing and sucking portion 14, thereby ensuring the communication between the air suction pipeline and the air inlet end, and the communication between the air exhaust pipeline 26 and the air outlet end.
Further, as shown in
The second waterproof seal 25 may be an elastic rubber pad, so that the thickness of the second waterproof seal 25 may be slightly larger than the distance between the edge of the third opening 20 and the edge of the air inlet end, which causes the second waterproof seal 25 to be deformed by an extrusion force. In this way, the second waterproof seal 25 may be more closely attached to the edge of the third opening 20 and the edge of the air inlet end, and in turn the gap 27 between the edge of the third opening 20 and the edge of the air inlet end is blocked more tightly, so that air carrying water vapor is prevented from entering the second accommodating chamber 13 from the gap between the edge of the third opening 20 and the edge of the air inlet end, and the drawing and sucking portion 14 is prevented from being located in a humid environment and subjected to the damp and the failure, thereby prolonging the service life of the drawing and sucking portion 14.
Further, as shown in
In other possible embodiments, as shown in
A reference may be made to the foregoing embodiments for the specific structure of the cleaning device, which will not be repeated herein. In this embodiment, since the cleaning device often needs to be cleaned or the dirt storage apparatus needs to be cleaned up, liquid such as a cleaning fluid or sewage may be adhered to the cleaning device. When the liquid flows downward to the gap 27 at the connection between the first storage apparatus 101 and the second storage apparatus 102, the waterproof mechanism 28 may prevent the external fluid from entering the cleaning device through the gap 27, thereby reducing the risk of the failure of the electronic components in the cleaning device located in a humid environment and thus subjected to the damp, and prolonging the service life and improving the use safety of the cleaning device.
In the embodiment described above, as shown in
The second waterproof stopper 2801 and the first storage apparatus 101 are integrally formed, and the third waterproof stopper 2802 and the second storage apparatus 102 are integrally formed, so that not only are the process of assembling the second waterproof stopper 2801 and the first storage apparatus 101 and the process of assembling the third waterproof stopper 2802 and the second storage apparatus 102 omitted to simplify the manufacturing process, but also there is no seam between the second waterproof stopper 2801 and the first storage apparatus 101, and between the third waterproof stopper 2802 and the second storage apparatus 102. Therefore, the waterproof mechanism 28 has a better waterproof effect.
The clearance fitting between the second waterproof stopper 2801 and the third waterproof stopper 2802 means that the second waterproof stopper 2801 and the third waterproof stopper 2802 are at least partially staggered and overlapped, but there is a certain distance between the second waterproof stopper 2801 and the third waterproof stopper 2802. In other words, the second waterproof stopper 2801 is not in contact with the third waterproof stopper 2802.
The gap between the second waterproof stopper 2801 and the third waterproof stopper 2802 can accelerate dissipation of heat from the electronic components in the cleaning device, which facilitates heat dissipation of the electronic components.
The second waterproof stopper 2801 and the third waterproof stopper 2802 are at least partially staggered and overlapped. When the liquid flows to the second waterproof stopper 2801, the second waterproof stopper 2801 stops the liquid to prevent the liquid from entering the cleaning device, and then the liquid continues to flow downward along the outer surface of the second waterproof stopper 2801 until it flows to the bottom of the second storage apparatus 102 and finally drops on the ground. The third waterproof stopper 2802 plays the role of secondary waterproofing. When the cleaning device is moving or shakes, the liquid flowing through the second waterproof stopper 2801 flows toward the inside of the cleaning device by an external force. In this case, the third waterproof stopper 2802 may stop the liquid to prevent the liquid from entering the cleaning device, and the liquid may flow outward to the outer surface of the second storage apparatus 102 along the third waterproof stopper 2802. Afterwards, the liquid continues to flow downward along the outer surface of the second storage apparatus 102 until it flows to the bottom of the second storage apparatus 102 and finally drops on the ground. Therefore, the second waterproof stopper 2801 and the third waterproof stopper 2802 cooperate to stop twice the liquid that flows from top to bottom, so that the waterproof effect of the waterproof mechanism 28 is improved.
Specifically, as shown in
The protrusion 28011 is at least partially embedded into the second notch 28022 of the first stepped structure, so that the protrusion 28011 and the second stepped structure 28021 may be at least partially staggered and overlapped. When the liquid flows to the protrusion 28011, the protrusion 28011 stops the liquid to prevent the liquid from entering the cleaning device, and the protrusion 28011 also plays the role of flow guiding. The liquid continues to flow downward along the outer surface of the protrusion 28011 until it flows to the bottom of the second storage apparatus 102 and finally drops on the ground. The third waterproof stopper 2802 plays the role of secondary waterproofing. When the cleaning device is moving or shakes, the liquid flowing through the protrusion 28011 flows toward the inside of the cleaning device by an external force. In this case, the second stepped structure 28021 may stop the liquid to prevent the liquid from entering the inside of the cleaning device, and the liquid may flow outward to the outer surface of the second storage apparatus 102 along the surface of the second notch 28022. Afterwards, the liquid continues to flow downward along the outer surface of the second storage apparatus 102 until it flows to the bottom of the second storage apparatus 102 and finally drops on the ground. Therefore, the protrusion 28011 and the stepped structure cooperate to stop twice the liquid that flows from top to bottom.
Further, as shown in
The inner side wall of the protrusion 28011 is gradually inclined outward from top to bottom, which means that the inner side wall of the protrusion 28011 is gradually inclined from top to bottom in a direction approaching the outer surface of the first storage apparatus 101. Similarly, the side wall of the second stepped structure 28021 is gradually inclined outward from top to bottom, which means that the side wall of the second stepped structure 28021 is gradually inclined from top to bottom in a direction approaching the outer surface of the second storage apparatus 102.
The inner side wall of the protrusion 28011 is gradually inclined outward from top to bottom, which may form a wedge-shaped structure on the protrusion 28011, so that the protrusion 28011 may be conveniently embedded into the second notch 28022 of the second stepped structure 28021. The side wall of the second stepped structure 28021 is gradually inclined outward from top to bottom, so that the liquid stopped by the side wall may flow to the outside of the cleaning device at a certain speed when flowing downward along the side wall, which reduces the possibility of the liquid remaining in the second notch 28022 and enables the waterproof effect to be better.
Further, as shown in
As shown in
The part of the package 24 close to the bottom of the first storage apparatus 101 extends downward and is flush with the bottom of the protrusion 28011, so that the integrity of the protrusion 28011 can be ensured, and the situation that the waterproof performance is reduced due to breakage of the protrusion 28011 can be avoided.
In some possible embodiments, as shown in
The cleaning fluid storage apparatus is arranged at the lower portion, which makes it convenient for a user to inject the cleaning fluid into the cleaning fluid storage apparatus. Especially, if the cleaning device is a large-scale floor scrubber, and the cleaning fluid storage apparatus has a large volume, arranging the cleaning fluid storage apparatus at the lower portion is more convenient for the user to inject the fluid.
Further, as shown in
Specifically, the first waterproof seal 7 is waterproof foam 3801.
The waterproof foam 3801 may be made of a foamed foam base material, which has the characteristics of excellent waterproof performance and high temperature resistance. The foamed foam base material includes EVA foam, PE foam, PU foam, acrylic foam and high-foaming foam. The waterproof foam 3801 may be fixed around the fluid injection port by means of bonding, and of course, other fixing methods may also be adopted, which is not strictly limited in this embodiment.

The fluid injection joint 1022 is gradually inclined outward from bottom to top, which means that the fluid injection joint 1022 is gradually inclined from bottom to top in a direction approaching the outer surface of the second storage apparatus 102, so that when the user connects the fluid injection joint 1022 to the water pipe, components above the fluid injection port 1 are prevented from interfering with the connection operation. thereby facilitating the connection operation and improving the connection efficiency.
In some other possible embodiments, as shown in
A reference may be made to the foregoing embodiments for the specific structure of the cleaning device, which will not be repeated herein. The second electronic assembly 32 may include, but is not limited to, a controller and a peripheral circuit. The shape of the third accommodating chamber 33 may be set according to the arrangement of other components in the main body 1, and may be set into a regular shape, for example, a cuboid, or a special shape. The volume of the third accommodating chamber 33 is larger than that occupied by the second electronic assembly 32, which facilitates not only the mounting of the second electronic assembly 32, but also the heat dissipation of the second electronic assembly 32. Moreover, the third accommodating chamber 33 is not a closed space, that is, the top of the third accommodating chamber 33 is open. In other words, the top of the third accommodating chamber 33 is provided with a fifth opening 31, which facilitates air circulation, is more conductive to heat dissipation of the second electronic assembly 32 and improves the heat dissipation effect of the second electronic assembly 32.
In this embodiment, the vertical distance between the first area 34 at the bottom of the third accommodating chamber 33 and the bottom of the main body 1 is greater than that between other areas at the bottom of the third accommodating chamber 33 and the bottom of the main body 1. In other words, the bottom of the first area 34 is higher than other areas. A water accumulation cavity is formed in other areas by using a height difference between the first area 34 and other areas. In this way, the liquid falling into the first area 34, when entering the third accommodating chamber 33 from the top of the third accommodating chamber 33, flows into the water accumulation cavity due to the height difference, so that the liquid is not easy to accumulate in the first area 34. In addition, the second electronic assembly 32 is located higher than the water accumulation cavity, and thus is less susceptible to immersion in the accumulated water in the water accumulation cavity, thereby reducing the risk of the failure of the second electronic assembly 32 subjected to the damp due to immersion in the liquid, and prolonging the service life and improving the use safety of the cleaning device.
It can be understood that the height difference between the first area 34 and other areas may be designed according to the height of the second electronic assembly 32 and the total height of the accommodating chambers, which is not strictly limited in this embodiment.
Further, as shown in
In specific applications, the shielding area of the second shielding portion 30 is greater than or equal to the area occupied by the second electronic assembly 32, and the shielding area of the second shielding portion 30 is smaller than the area of the fifth opening 31.
In order to ensure that the second electronic assembly 32 is not wetted by the liquid entering the third accommodating chamber 33 from above, the shielding area of the second shielding portion 30 should be at least the same as that occupied by the second electronic assembly 32. In some possible embodiments, the shielding area of the second shielding portion 30 is larger than the area occupied by the second electronic assembly 32 and smaller than the area of the fifth opening 31. In other words, the fifth opening 31 at the top of the third accommodating chamber 33 is still partially not covered by the second shielding portion 30, which not only improves the shielding effect but also ensures air circulation, without affecting the heat dissipation effect of the second electronic assembly 32.
Further, the second shielding portion 30 is detachably mounted on the side wall of the third accommodating chamber 33, which not only facilitates mounting of the second shielding portion 30 but also allows a worker to remove the second shielding portion 30 in the event that the second electronic assembly 32 needs to be inspected or maintained, thereby preventing the second shielding portion 30 from obstructing maintenance or operation of the assembly.
Specifically, as shown in
The sucker 37 may be of an elastic cup structure. When the second shielding portion 30 is mounted, the sucker 37 is attached to the side wall of the third accommodating chamber 33, and air in the sucker 37 is squeezed out, so that the second shielding portion 30 is fixed to the side wall by external pressure. When the second shielding portion 30 is detached, the edge of the sucker 37 is pried up to let air enter the sucker 37, so that the air pressures inside and outside the sucker 37 are the same; and in this way, the sucker 37 may be separated from the side wall, that is, the second shielding portion 30 is separated from the side wall.
In this embodiment, the detachable connection between the second shielding portion 30 and the side wall is realized by the sucker 37, which is not only simple in structure, but also unnecessary to add an additional connection structure to the side wall, thereby reducing the manufacturing difficulty.
Specifically, the second shielding portion 30 is a waterproof board. The waterproof board may be made of a plastic material. The plastic material has the characteristics of corrosion resistance and light weight, thereby not only prolonging the service life of the second shielding portion 30, but also reducing the weight of the second shielding portion 30. The plastic material includes polyvinyl chloride, polyethylene, polypropylene, polystyrene, polycarbonate, etc.
In specific applications, as shown in
The third accommodating chamber 33 is isolated from the cleaning fluid accommodating space, which means that the cleaning fluid in the cleaning fluid storage apparatus is prevented from flowing into the third accommodating chamber 33. In other words, under normal circumstances, the third accommodating chamber 33 and the space for accommodating the cleaning fluid are independent of each other and do not affect each other, that is, the cleaning fluid in the cleaning fluid storage device is prevented from leaking into the third accommodating chamber 33 under normal circumstances.
The third accommodating chamber 33 is arranged in the cleaning fluid storage apparatus, so that it is unnecessary to reserve a space on the main body 1 for additionally arranging an accommodating chamber, which enables the structure to be more compact and reduces the overall size of the main body 1.
Further, as shown in
The cleaning fluid storage apparatus is arranged at the lower portion, which makes it convenient for the user to inject the cleaning fluid into the cleaning fluid storage apparatus. Especially, if the cleaning device is a large-scale floor scrubber, and the cleaning fluid storage apparatus has a large volume, arranging the cleaning fluid storage apparatus at the lower portion is more convenient for the user to inject the fluid.
Further, as shown in
When the water accumulation cavity is full of liquid and the liquid overflows into the first area 34 or the liquid falls into the first area 34 due to shaking of the main body 1, the liquid may flow to the outside of the cleaning fluid storage apparatus through the second flow drainage channel 9, so that it is ensured that water is prevented from accumulating in the first area 34, that is, the second electronic assembly 32 is prevented from being immersed in the liquid, thereby enabling the waterproof effect of the third accommodating chamber 33 to be better. Of course, if the bottom of the cleaning fluid storage apparatus is also provided with other components, for example, a base plate 103, correspondingly, a hole is also formed in the base plate 103 corresponding to the first flow drainage port 35, so that the liquid can be discharged to the outside of the cleaning device.
Further, as shown in
By using the second flow drainage channel 9, the accumulated water in other areas, i.e., the accumulated water in the water accumulation cavity, directly flows to the outside of the cleaning fluid storage apparatus through a fourth flow drainage channel 36, so that there is no water accumulated in other areas. In this way, the second electronic assembly 32 is prevented from being immersed in liquid, and the humidity in the third accommodating chamber 33 can be reduced, so that the second electronic assembly 32 can be kept in a relatively dry environment, thereby further reducing the risk of the failure of the electronic assembly subjected to the damp. Of course, if the bottom of the cleaning fluid storage apparatus is also provided with other components, for example, the base plate 103, correspondingly, a through hole is also formed in the base plate 103 corresponding to the second flow drainage port 36, so that the liquid can be discharged to the outside of the cleaning device.
In some other possible embodiments, as shown in
A reference may be made to the foregoing embodiments for the specific structure of the cleaning device. The package 24 may seal some gaps or recesses 39 formed in the main body 1 during the process or assembly, so as to improve the overall airtightness of the first storage apparatus 101 and prevent some external fluids (for example, water splashed on the main body 1 during cleaning) from flowing into the first storage apparatus 101 through the gaps or recesses 39 on the first storage apparatus 101. In addition, the package 24 may also be provided with a sensing portion, which solves the problem that the first storage apparatus 101 formed by the rotational molding process cannot be directly provided with sensing components, and facilitates implementation of intelligence and automation of the self-moving cleaning device. The package 24 may be made of, for example, a plastic material and formed integrally. The plastic material has the characteristics of excellent elasticity, high toughness, light weight, excellent chemical stability, vibration resistance, etc., and thus can meet the use requirements of the mounting of members. The plastic material includes polyvinyl chloride, polyethylene, polypropylene, polystyrene, polycarbonate, etc.
In this embodiment, the liquid may be prevented from entering the cleaning device from the seam between the package 24 and the main body 1 by using the fourth waterproof seal 38 arranged at the connection between the package 24 and the main body 1, so that the risk of the failure of the electronic components in the cleaning device located in a humid environment and thus subjected to the damp is reduced, thereby prolonging the service life and improving the use safety of the cleaning device.
In the embodiment described above, the fourth waterproof seal 38 is elastic, and the fourth waterproof seal 38 is in interference fit with the package 24 and the main body 1.
The fourth waterproof seal 38 may be made of an elastic sealing material, for example, rubber, and the material of the fourth waterproof seal 38 is not strictly limited in this embodiment.
The fourth waterproof seal 38 is in interference fit with the package 24 and the main body 1. In other words, the fourth waterproof seal 38 is elastically deformed by an extrusion force of the package 24 and the main body 1, so that the fourth waterproof seal 38 can be attached to the package 24 and the main body 1 more closely, and the seam between the package 24 and the main body 1 is blocked more tightly, thereby improving the waterproof effect.
For the packages 24 in different positions, different waterproof seals are adopted for sealing in the present application.
In some possible embodiments, as shown in
The waterproof foam 3801 may be made of a foamed waterproof foam base material, which has the characteristics of excellent waterproof performance and strong temperature resistance. The foamed waterproof foam base material includes EVA waterproof foam, PE waterproof foam, PU waterproof foam, acrylic waterproof foam and high-foaming foam.
In some other possible embodiments, as shown in
For the case where the main body 1 is provided with the recess 39, the seam between the package 24 and the main body 1 is sealed in a waterproof manner by cooperation between the waterproof foam 3801 and the first rubber plug 3802. The recess 39 can be filled with the first rubber plug 3802 that has a certain volume, and the first rubber plug 3802 is used for waterproof sealing of the recess 39. The waterproof foam 3801 is arranged between the first rubber plug 3802 and the package 24, and is used for waterproof sealing of the gap between the first rubber plug 3802 and the package 24, so that the waterproof sealing effect is improved. Moreover, the first rubber plug 3802 and the waterproof foam 3801 as a whole are in interference fit between the package 24 and the recess 39, so that the waterproof foam 3801 and the first rubber plug 3802, the waterproof foam 3801 and the package 24, and the first rubber plug 3802 and the main body 1 can be attached to each more closely, and the seam between the package 24 and the main body 1 can be blocked more tightly, thereby improving the waterproof effect.
Further, as shown in
The wire harness 40 may be composed of wires connecting various electronic components, for example, a wire connecting a controller and a sensor. As shown in
In some other possible embodiments, as shown in
The waterproof sealing strip 3803 has excellent abrasion resistance, hydrophobicity and corrosion resistance, so that the sealing strip can well seal the gap between the package 24 at the top of the main body 1 and the main body 1, which in turn can effectively prevent the liquid from flowing into the main body 1 through the gap between the package 24 at the top of the main body 1 and the main body 1.
In specific applications, the cleaning device further includes a detachable connector, the package 24 is connected to the main body 1 by means of the detachable connector, and a fifth waterproof seal 41 is arranged at the connection between the detachable connector and the package 24.
The package 24 is detachably connected to the main body 1, so that it is convenient to replace the package 24 when the package 24 is damaged by an external force. The fifth waterproof seal 41 seals the gap between the detachable connector and the package 24, so as to prevent the liquid from flowing into the main body 1 through the gap.
Specifically, as shown in
The bolt 43 is in threaded connection with the first screw hole 44 and the second screw hole 45 to realize the detachable connection between the package 24 and the main body 1. The gap between the bolt head 4301 and the package 24 is sealed by the elastic washer 4101 arranged between the bolt head 4301 and the package 24, and the elastic washer 4101 is in interference fit between the bolt head 4301 and the package 24. In this way, the elastic washer 4101 is attached to the bolt head 4301 and the package 24 more closely, so that the gap between the bolt head 4301 and the package 24 is blocked more tightly by the elastic washer 4101, thereby improving the waterproof effect.
Further, as shown in
The second rubber plug 4102 blocks the groove 42 to prevent the liquid from flowing into the groove 42. In this way, the second rubber plug 4102 and the elastic washer 4101 may cooperate to form twice waterproof sealing of the gap between the bolt 43 and the package 24, which further improves the waterproof effect on the gap between the bolt 43 and the package 24. In addition, the second rubber plug 4102 is mounted in the groove 42 in an interference fit manner, so that the second rubber plug 4102 and the inner wall of the groove 42 are attached to each other more closely, thereby enabling the waterproof effect to be better.
In the embodiment described above, as shown in
