[0029] This disclosure provides a cleaning device, which can be a robot vacuum cleaner, a robot mop, a robot vacuum and mop combo, or other cleaning devices that meet the requirements.

[0030] In some embodiments, the cleaning equipment includes, but is not limited to, a device body, a mobile platform, sensing components, control components, cleaning components, energy components, and human-machine interaction components. These components coordinate with each other to enable the cleaning equipment to move autonomously to perform its cleaning function. The functional elements constituting these components are integrated into the device body. It is understood that the cleaning equipment can be a self-moving cleaning device, which is a device that automatically performs cleaning operations in a designated area without user intervention.

[0031] Referring to Figures 1 and 2, Figure 1 is a structural schematic diagram of the cleaning equipment provided in this disclosure, and Figure 2 is a rear view schematic diagram of the cleaning equipment provided in this disclosure. The cleaning equipment provided in this embodiment includes: a mobile platform 2, a housing, and an airflow generator 3. The housing is disposed on the mobile platform 2, and a receiving cavity 11 is formed within the housing. The receiving cavity 11 has a dust collection chamber 12, and the receiving cavity 11 includes a first receiving area. Along the traveling direction X of the cleaning equipment, the first receiving area is located in front of the dust collection chamber 12. The airflow generator 3 is disposed in the first receiving area and communicates with the dust collection chamber 12 to generate negative pressure within the dust collection chamber 12.

[0032] In this embodiment of the disclosure, the mobile platform 2 can generate movement to drive the cleaning equipment to move autonomously within the area to be cleaned. In some embodiments, the area to be cleaned may be the floor, carpet, or the like in a room.

[0033] In some embodiments, the mobile platform 2 may be a structure including three rollers arranged in a triangular pattern. A drive unit may be provided on one of the rollers to drive the roller to rotate, thereby moving the cleaning equipment.

[0034] In this embodiment, the housing can provide mounting points, support, and protection for other components in the cleaning equipment. The external shape and internal structure of the housing can be designed according to the shape and distribution of the other components in the cleaning equipment, so as to facilitate the installation of each component inside and outside the housing.

[0035] In some embodiments, as shown in FIG1, the housing can be configured to include a housing body 1 and a top cover (not shown in the figure). A cavity or bracket, etc., matching the moving platform 2 can be provided on the housing body 1, allowing the moving platform 2 to be connected to the housing body 1 and a portion of the moving platform 2 to be housed within the housing body 1. A receiving cavity 11 can be formed within the housing body 1, and a dustbin 12 can be provided within the receiving cavity 11. The opening of the dustbin 12 faces the bottom of the cleaning device, and the shape of the dustbin 12 can be configured according to the shape of the dust box of the cleaning device to facilitate the installation of the dust box within the dustbin 12. In some embodiments, the dustbin 12 can be located in the region of the receiving cavity 11 near the center of the housing body 1, and the long axis of the dustbin 12 can be perpendicular or nearly perpendicular to the traveling direction X of the cleaning device. The top cover can be fixedly connected to the opening of the housing body 1 to cover the receiving cavity 11.

[0036] It should be noted that during operation, the cleaning equipment can be moved forward or backward via the mobile platform 2. For ease of understanding and description, the direction of travel X described in this embodiment represents the direction in which the cleaning equipment moves forward, so as to define and distinguish the front (front end) and rear (rear end) of the cleaning equipment and its components.

[0037] In another embodiment, the accommodating cavity 11 can be configured to include at least two accommodating areas along the traveling direction X of the cleaning equipment. In some embodiments, two rollers in the moving platform 2 can be respectively positioned on both sides of the dustbin 12 in a direction perpendicular to the traveling direction X of the cleaning equipment. In this way, the accommodating cavity 11 can be divided into two accommodating areas by the dustbin 12 and the two rollers located on both sides of the dustbin 12. That is, along the traveling direction X of the cleaning equipment, the area in the accommodating cavity 11 located in front of the dustbin 12 is the first accommodating area, and the area in the accommodating cavity 11 located behind the dustbin 12 is the second accommodating area.

[0038] In this embodiment of the present disclosure, as shown in FIG1, the airflow generator 3 can accelerate the airflow speed around the cleaning device to create a negative pressure in the area adjacent to the airflow generator 3. The airflow generator 3 can be disposed within the first accommodating area, that is, the airflow generator 3 is located in the area near the front end of the cleaning device within the accommodating cavity 11. In some embodiments, the airflow generator 3 can be an axial fan, a centrifugal fan, or a plasma fan, etc.

[0039] In some embodiments, an air inlet channel 6 can be provided between the airflow generator 3 and the dustbin 12 to connect the air inlet of the airflow generator 3 to the dustbin 12. One end of the air inlet channel 6 can be connected to the air inlet of the airflow generator 3, for example, along the thickness direction Z of the cleaning equipment, the air inlet channel 6 can be connected to the upper end of the air inlet of the airflow generator 3. The other end of the air inlet channel 6 can be connected to the dustbin 12, for example, a notch matching the air inlet channel 6 can be provided on the wall of the dustbin 12, and the air inlet channel 6 can be sealed to the edge of the notch. In this way, during the operation of the airflow generator 3, the speed at which the air in the dustbin 12 flows into the air inlet channel 6 can be accelerated, thereby making the air pressure inside the dustbin 12 lower than the air pressure outside the dustbin 12, so that debris can be sucked into the dust box located in the dustbin 12 through negative pressure.

[0040] The cleaning equipment provided in this embodiment includes an airflow generator 3 within the housing, which is connected to the dustbin 12. The airflow generator 3 creates negative pressure within the dustbin 12, facilitating the suction of debris into the dustbin, thus collecting it from the surface to be cleaned. Furthermore, placing the airflow generator 3 within the first accommodating area in front of the dustbin 12 within the accommodating cavity 11 reduces its impact on the space behind the dustbin 12. This allows for the placement of other components within the housing, improving the utilization of the internal space and facilitating the addition of other components, thereby enhancing the equipment's performance.

[0041] In some embodiments of this disclosure, as shown in FIG1, the accommodating cavity 11 has a power supply compartment 13, which is located in the first accommodating area.

[0042] In this embodiment of the disclosure, the cleaning equipment needs to be powered by electricity to operate the components in the cleaning equipment during operation. Therefore, a battery can be used to power the cleaning equipment. For example, a rechargeable battery (a battery that can be charged and discharged multiple times) or a regular battery can be used to power the cleaning equipment.

[0043] In some embodiments, a power compartment 13 for installing a battery can be provided within the accommodating cavity 11 of the housing. The shape of the power compartment 13 can be configured according to the shape of the battery used. In some embodiments, the power compartment 13 can be configured as a box-shaped structure with an approximate cuboid shape. The opening of the power compartment 13 is located on the surface of the housing facing the bottom of the cleaning device, and the cover of the power compartment 13 can be opened from the bottom of the cleaning device.

[0044] In another embodiment, the power supply compartment 13 can be placed in the first receiving area of ​​the receiving cavity 11, that is, in the area in the receiving cavity 11 located in front of the dust box compartment 12 along the traveling direction X of the cleaning equipment.

[0045] In the above embodiments, since a power supply compartment 13 is provided inside the accommodating cavity 11, batteries or other devices that provide power to the cleaning equipment can be installed inside the power supply compartment 13. Furthermore, the power supply compartment 13 can separate the inside of the accommodating cavity 11 from the outside of the accommodating cavity 11, which helps to reduce the risk of foreign objects entering the accommodating cavity 11.

[0046] In some embodiments of this disclosure, as shown in FIG1, the airflow generator 3 and the power supply compartment 13 are distributed in the first accommodating area along the first direction Y, and there is a gap between the airflow generator 3 and the power supply compartment 13. The first direction Y is a direction perpendicular to both the travel direction X and the thickness direction Z of the cleaning device.

[0047] In this embodiment of the present disclosure, when both the power supply compartment 13 and the airflow generator 3 are disposed in the first accommodating area within the accommodating cavity 11, the power supply compartment 13 and the airflow generator 3 can be arranged along the first direction Y within the first accommodating area. Furthermore, a certain distance can be maintained between the power supply compartment 13 and the airflow generator 3. In some embodiments, the distance between the power supply compartment 13 and the airflow generator 3 along the first direction Y can be 10mm to 30mm.

[0048] In some embodiments, along the first direction Y, at least a portion of the orthographic projection of the airflow generator 3 onto the projection plane may coincide with the orthographic projection of the power supply compartment 13 onto the projection plane. This projection plane is a virtual plane parallel to the travel direction X and parallel to the thickness direction Z of the cleaning device.

[0049] In the above embodiments, since the airflow generator 3 and the power supply compartment 13 are distributed along the first direction Y within the first accommodating area, there is a large space near the front end of the cleaning equipment within the first accommodating area, which facilitates the placement of other components within the cleaning equipment within the first accommodating area. Furthermore, the gap between the airflow generator 3 and the power supply compartment 13 helps to accelerate the dissipation of heat generated by the battery and other components within the power supply compartment 13, as well as the heat generated by the airflow generator 3.

[0050] In some embodiments of this disclosure, the cleaning device further includes a circuit board (not shown) with at least a portion of the circuit board stacked with the airflow generator 3 along the thickness direction Z of the cleaning device.

[0051] In this embodiment of the present disclosure, the circuit board in the cleaning device can be disposed within the first accommodating area of ​​the accommodating cavity 11. The shape of the circuit board can be set according to the shape of the remaining space within the first accommodating area. In some embodiments, the circuit board can be set as an irregular polygon.

[0052] In some embodiments, along the thickness direction Z of the cleaning device, at least a portion of the circuit board can be positioned above the airflow generator 3, that is, at least a portion of the circuit board is stacked with the airflow generator 3.

[0053] In the above embodiments, by stacking at least a portion of the circuit board with the airflow generator 3 along the thickness direction Z of the cleaning device, the circuit board can be located within the first accommodating area, and the shape of the circuit board can be set according to the space within the first accommodating area, making it convenient to install the circuit board within the accommodating cavity 11. This also improves the compactness of the internal components of the cleaning device, which is beneficial to improving the space utilization of the accommodating cavity 11, thereby contributing to the thinning and miniaturization of the cleaning device.

[0054] In some embodiments of this disclosure, as shown in FIG1, the accommodating cavity 11 has a heat dissipation channel 5, the first end 51 of the heat dissipation channel 5 is connected to the air outlet of the airflow generator 3, and the second end 52 of the heat dissipation channel 5 extends to the outside of the housing.

[0055] In this embodiment of the present disclosure, when the airflow generator 3 generates negative pressure in the dust box 12, the airflow generator 3 needs to discharge the air it has drawn in. Therefore, a heat dissipation channel 5, which serves as an exhaust channel, can be provided to the airflow generator 3.

[0056] In some embodiments, the structure and shape of the heat dissipation channel 5 can be configured according to the space within the accommodating cavity 11. In some embodiments, at least a portion of the heat dissipation channel 5 can be disposed within the gap between components located in the first accommodating area, and at least a portion of the heat dissipation channel 5 can be configured as a closed tube. The first end 51 of the heat dissipation channel 5 can be connected to the air outlet of the airflow generator 3, and a sealing ring or the like can be provided between the first end 51 of the heat dissipation channel 5 and the air outlet of the airflow generator 3 to seal the connection between the first end 51 of the heat dissipation channel 5 and the air outlet of the airflow generator 3. The second end 52 of the heat dissipation channel 5 can be disposed on the shell wall of the housing, so that the second end 52 of the heat dissipation channel 5 extends to the outside of the accommodating cavity 11.

[0057] In the above embodiment, since a heat dissipation channel 5 is provided in the accommodating cavity 11 and the first end 51 of the heat dissipation channel 5 is connected to the air outlet of the airflow generator 3, the airflow generator 3 can be formed through the heat dissipation channel 5, which facilitates the rapid guidance and discharge of the air drawn in by the airflow generator 3 to the outside of the accommodating cavity 11 by using the heat dissipation channel 5.

[0058] In some possible embodiments of this disclosure, as shown in FIG1, the heat dissipation channel 5 has a negative pressure notch 53, and the heat dissipation channel 5 is connected to the accommodating cavity 11 through the negative pressure notch 53.

[0059] In this embodiment of the present disclosure, at least one negative pressure notch 53 may be provided on the channel wall of the heat dissipation channel 5 so that the heat dissipation channel 5 and the receiving cavity 11 are connected through the negative pressure notch 53. In some embodiments, the negative pressure notch 53 may be provided on the portion of the heat dissipation channel 5 located in the first receiving area, thereby connecting the heat dissipation channel 5 with the first receiving area.

[0060] In some embodiments, along the thickness direction Z of the cleaning device, the negative pressure notch 53 can be disposed on the side of the heat dissipation channel 5 facing the top of the cleaning device, or the negative pressure notch 53 can be disposed on the side of the heat dissipation channel 5 facing the center of the receiving cavity 11. Furthermore, the negative pressure notch 53 can be located in a region close to the edge of the receiving cavity 11; for example, the negative pressure notch 53 can have a distance of 2 mm to 20 mm between it and the shell wall of the housing.

[0061] In the above embodiment, since a negative pressure notch 53 is provided on the heat dissipation channel 5, the heat dissipation channel 5 can be connected to the accommodating cavity 11 through the negative pressure notch 53. In this way, when the high-velocity gas generated by the airflow generator 3 flows through the heat dissipation channel 5, the air pressure near the negative pressure notch 53 can be reduced, that is, the air pressure near the negative pressure notch 53 is less than the air pressure in other areas of the accommodating cavity 11. As a result, the air in the accommodating cavity 11 can flow towards the negative pressure notch 53 under the action of the pressure difference. In turn, the air around the circuit board can be discharged to the outside of the accommodating cavity 11 through the negative pressure notch 53 and the heat dissipation channel 5, which is beneficial to improving the heat dissipation efficiency of the circuit board.

[0062] In some possible embodiments of this disclosure, as shown in FIG1, a portion of the heat dissipation channel 5 passes through the power supply compartment 13, and the compartment wall of the power supply compartment 13 is heat-transferringly connected to the channel wall of the heat dissipation channel 5, or the compartment wall is part of the channel wall.

[0063] In this embodiment of the present disclosure, a portion of the heat dissipation channel 5 may be disposed adjacent to the power supply compartment 13 so as to absorb and accelerate the dissipation of heat generated by the battery and other components in the power supply compartment 13 through the heat dissipation channel 5.

[0064] In some embodiments, a wall channel 54 matching the shape of the power supply compartment 13 can be provided. The wall channel 54 can be configured as a tubular structure, serving as part of the heat dissipation channel 5. In some embodiments, the shape of the wall channel 54 can be set according to the shape of the gap between the power supply compartment 13 and other components adjacent to the power supply compartment 13. One end of the wall channel 54 can be configured to match the air outlet of the airflow generator 3, and this end of the wall channel 54 can be connected to the air outlet of the airflow generator 3 as the first end 51 of the heat dissipation channel 5.

[0065] In another embodiment, the channel wall of the chamber wall 54 can abut against the chamber wall of the power supply chamber 13. Alternatively, a thermally conductive material such as thermally conductive grease or silicone can be placed between the channel wall of the chamber wall 54 and the chamber wall of the power supply chamber 13 to allow the heat absorbed by the chamber wall of the power supply chamber 13 to be quickly transferred to the channel wall of the chamber wall 54. Alternatively, a notch matching the power supply chamber 13 can be provided on the chamber wall 54. This way, after the chamber wall 54 is installed in the first accommodating area, the chamber wall of the power supply chamber 13 can seal the notch on the chamber wall 54, meaning the chamber wall of the power supply chamber 13 becomes part of the channel wall of the chamber wall 54, forming a complete tubular structure. This allows the heat absorbed by the chamber wall of the power supply chamber 13 to be directly transferred to the heat dissipation channel 5.

[0066] In another embodiment, a first through hole can be provided on the wall of the power supply compartment 13 near the compartment wall channel 54. Correspondingly, a second through hole corresponding to the first through hole can be provided on the channel wall of the compartment wall channel 54, so that the interior of the compartment wall channel 54 and the interior of the power supply compartment 13 are connected through the first and second through holes. In this case, the internal space of the power supply compartment 13 can also serve as part of the heat dissipation channel, and the airflow generated by the airflow generator 3 can drive the airflow within the power supply compartment 13 to flow rapidly.

[0067] In the above embodiments, since the channel wall of the heat dissipation channel 5 is heat-transferringly connected to the wall of the power compartment 13, or the wall of the power compartment 13 is part of the channel wall of the heat dissipation channel 5, the heat absorbed by the wall of the power compartment 13 can be quickly transferred to the heat dissipation channel 5, thereby accelerating the heat dissipation speed of the power compartment 13 and improving the heat dissipation efficiency of the battery in the power compartment 13.

[0068] In some possible embodiments of this disclosure, as shown in FIG1, the second end 52 of the heat dissipation channel 5 forms an acute angle C with the direction of travel X, and the second end 52 faces the rear end of the cleaning device.

[0069] It can be understood that the second end 52 of the heat dissipation channel 5 can be understood as the end face of the second end 52 of the heat dissipation channel 5. The virtual plane formed by the travel direction X and the thickness direction Z forms an angle C with the end face of the second end 52.

[0070] In this embodiment, another part of the heat dissipation channel 5 can be formed between the shell wall of the housing and the external trim (e.g., the buffer) of the cleaning device. In some embodiments, there can be a gap between the buffer 7 of the cleaning device and the shell wall of the housing body 1. After the buffer, top cover, etc. are assembled onto the housing body 1, a shell wall channel 55 (the area shown by the blue dashed rectangle in FIG1) can be formed as another part of the heat dissipation channel 5. Furthermore, there can be a gap between the end of the bin wall channel 54 near the shell wall channel 55 and the shell wall channel 55 (the area shown by the red dashed triangle in FIG1). This gap area can be used as a negative pressure gap 53. In this way, the shell wall channel 55, the bin wall channel 54, and the negative pressure gap 53 together form the heat dissipation channel 5.

[0071] In some embodiments, when the shell wall channel 55 is provided, the end of the shell wall channel 55 away from the negative pressure gap 53 can be directed toward the rear end of the cleaning device. That is, the extension direction of the gap formed on the shell wall of the shell body 1 as the second end 52 of the heat dissipation channel 5 forms an acute angle C with the travel direction X of the cleaning device, and the extension direction of the gap is directed toward the rear end of the cleaning device, so that the second end 52 of the heat dissipation channel 5 is directed toward the rear end of the cleaning device.

[0072] In another embodiment, the buffer 7 can be configured as a semi-annular structure that matches the shape of the shell body 1. The buffer 7 can be movably connected to the shell wall of the shell body 1 by means of an elastic element (e.g., a spring), and a sensor can be placed between the buffer 7 and the shell wall. In this way, when the cleaning device collides with an object, the buffer 7 will move relative to the shell body 1, thereby triggering the sensor and obtaining information about the collision of the cleaning device. As shown in FIG1, the second end 52 of the heat dissipation channel 5 can be located at the rear end of the buffer 7 (the end of the buffer 7 closer to the rear end of the cleaning device). In this way, the airflow generated by the airflow generator 3 can be guided to the rear side of the cleaning device and blown out towards the rear side of the cleaning device through the heat dissipation channel 5.

[0073] In the above embodiment, since the second end 52 of the heat dissipation channel 5 faces the rear end of the cleaning device, during the process of the airflow generator 3 generating airflow through the heat dissipation channel 5 and discharging it out of the accommodating cavity 11, the airflow can be blown out toward the rear end of the cleaning device in the direction of travel X, thereby reducing the risk that the airflow blown out from the heat dissipation channel 5 will blow the garbage to be cleaned in front of the cleaning device to outside the range that the cleaning device can clean.

[0074] In some possible embodiments of this disclosure, as shown in Figures 1 and 2, the accommodating cavity 11 further includes a second accommodating area located on the side of the dust box 12 opposite to the first accommodating area, and the cleaning device further includes a distance detection component 4 disposed in the second accommodating area.

[0075] In this embodiment, the area within the accommodating cavity 11 near the rear end of the cleaning device can be designated as the second accommodating area. That is, along the traveling direction X of the cleaning device, the area within the accommodating cavity 11 located behind the dust box 12 is designated as the second accommodating area. The first accommodating area and the second accommodating area are located on opposite sides of the dust box 12.

[0076] In some embodiments, the distance detection component 4 can be disposed in the second accommodating area. For example, along the first direction Y, the distance detection component 4 can be located near the centerline of the accommodating cavity 11, and along the traveling direction X, the distance detection component 4 can be located in the area near the shell wall of the housing.

[0077] In another embodiment, the distance detection component 4 can be a lidar, infrared ranging sensor, ultrasonic sensor, etc., which can measure the distance between the cleaning equipment and the items in the area to be cleaned by the reflection of light or sound waves.

[0078] In the above embodiment, since a distance detection component 4 is provided in the second accommodating area, during the operation of the cleaning equipment, the distance information between the items at the rear of the cleaning equipment and the cleaning equipment can be obtained through the distance detection component 4, thereby enabling the cleaning equipment to achieve efficient path planning and accurately avoid obstacles.

[0079] In some possible embodiments of this disclosure, the cleaning device further includes a detection lifting mechanism disposed in the accommodating cavity 11, and a distance detection component 4 disposed in the detection lifting mechanism. The detection lifting mechanism can drive the distance detection component 4 to move along the thickness direction Z of the cleaning device.

[0080] In this embodiment of the present disclosure, a detection lifting mechanism can be provided for the distance detection component 4, so that the distance detection component 4 can be lifted and lowered along the thickness direction Z of the cleaning equipment through the detection lifting mechanism.

[0081] In some embodiments, the detection lifting mechanism can employ a matching screw and nut. The screw can be rotatably positioned within the second receiving area, and the drive motor is connected to the screw via a transmission connection. A groove can be provided on the nut fitted onto the screw to restrict the rotation of the nut. The distance detection component 4 is fixed to the nut. During the rotation of the screw driven by the drive motor, the nut can move up and down along the axis of the screw, thereby causing the distance detection component 4 to move up and down along the thickness direction Z of the cleaning equipment.

[0082] In another embodiment, the detection lifting mechanism can be a crank mechanism, cylinder, hydraulic cylinder, or other mechanism capable of generating linear motion. This disclosure does not limit the specific structure of the detection lifting mechanism.

[0083] In the above embodiments, since a detection lifting mechanism is provided for the distance detection component 4, the distance detection component 4 can be moved along the thickness direction Z of the cleaning equipment to the outside of the cleaning equipment through the detection lifting mechanism, thereby reducing the obstruction of the distance detection component 4 and expanding the detection range of the distance detection component 4. When the cleaning equipment passes through a low space, the detection lifting mechanism can be used to move the distance detection component 4 into the receiving cavity 11, making it easier for the cleaning equipment to pass through the low space.

[0084] In some possible embodiments of this disclosure, as shown in FIG2, a viewing window 14 is provided on the housing, and when the distance detection component 4 descends into the accommodating cavity 11, the detection light of the distance detection component 4 can pass through the viewing window 14.

[0085] In this embodiment, a viewing window 14 corresponding to the distance detection component 4 can be provided on the housing to allow the detection light generated by the distance detection component 4 to be transmitted through the viewing window 14. In some embodiments, a through hole serving as the viewing window 14 can be provided on the housing wall, and the through hole on the housing wall corresponds to the position of the distance detection component 4 when it is in the receiving cavity 11. A lens can be provided on the viewing window 14 to seal the viewing window 14 without affecting the transmission of the detection light.

[0086] In the above embodiment, since a viewing window 14 corresponding to the distance detection component 4 is provided on the housing, the detection light generated by the distance detection component 4 can still be transmitted through the viewing window 14 when the distance detection component 4 descends into the receiving cavity 11. In this way, the distance detection component 4 can still work normally when the cleaning equipment passes through a low space.

[0087] In some possible embodiments of this disclosure, the cleaning device further includes a cleaning lifting mechanism (not shown in the figure), which is connected to the cleaning component and is located in the second receiving area.

[0088] In this embodiment of the disclosure, cleaning components can be provided in the cleaning device. In some embodiments, two cleaning components can be provided at the bottom of the cleaning device, and the two cleaning components are located at the rear end of the bottom of the cleaning device. The cleaning component can be set as a circular mop, and a drive motor can be provided for the cleaning component to drive the circular mop to rotate, thereby wiping the floor or other surfaces in the area to be cleaned.

[0089] In some embodiments, a cleaning lifting mechanism can be provided for the cleaning component. This cleaning lifting mechanism can be located in the second receiving area and can employ a mechanism capable of generating linear motion, such as a guide rail and a chute. The cleaning component can be connected to the guide rail, which extends along the thickness direction Z of the cleaning equipment. Thus, the cleaning component can be moved along the thickness direction Z of the cleaning equipment via the cleaning lifting mechanism.

[0090] In the above embodiments, since a cleaning lifting mechanism is provided in the second accommodating area, the cleaning component can be driven to move along the thickness direction Z of the cleaning equipment through the cleaning lifting mechanism, thereby achieving separation of the cleaning component from the ground of the area to be cleaned or pressing it against the ground.

[0091] In addition, this disclosure also provides a cleaning system, which includes a base station and the cleaning equipment provided in any of the above embodiments. The base station is used to dock the cleaning equipment.

[0092] In this embodiment of the disclosure, when the cleaning equipment starts working, it departs from the base station to perform the cleaning task. When the cleaning equipment performs charging or other operations, such as water replenishment, and / or washing, and / or dust collection, it returns to the base station to complete the charging and other operations.

[0093] The cleaning system provided in this disclosure includes the cleaning equipment provided in any of the above embodiments. Therefore, it can improve the utilization rate of the internal space of the cleaning equipment and facilitate the addition of components inside the cleaning equipment to improve the performance of the cleaning equipment, thereby improving the performance of the cleaning system.

[0094] This disclosure provides a cleaning device and cleaning system capable of collecting garbage from surfaces to be cleaned.

[0095] The above embodiments are merely illustrative of the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure, and all should be covered within the scope of this disclosure. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
