[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0050] like Figures 1 to 5As shown, Embodiment 1 of this utility model provides a cleaning device, which includes a floor brush component. The floor brush component includes a housing assembly 10 and a cleaning component 20. The cleaning component 20 includes a first connecting part 21, a second connecting part 22, and a roller brush part 23. The second connecting part 22 is disposed on the housing assembly 10. The first connecting part 21 includes a connecting arm 211 and a shaft component 212 disposed on the connecting arm 211. The connecting arm 211 is detachably connected to the housing assembly 10. One end of the roller brush part 23 is rotatably disposed on the shaft component 212 and detachably connected to the shaft component 212. The other end of the roller brush part 23 is rotatably disposed on the second connecting part 22 and detachably connected to the second connecting part 22.

[0051] By applying the technical solution of this utility model, when the roller brush part 23 of the cleaning component 20 is severely worn after long-term use and needs to be replaced, the connection between the connecting arm 211 and the housing component 10 is disconnected, the connection between the shaft component 212 and the roller brush part 23 is disconnected, and then the connection between the roller brush part 23 and the second connecting part 22 is disconnected, and the roller brush part 23 can be replaced. When replacing the new roller brush part 23, one end of the roller brush part 23 is installed on the second connecting part 22, the shaft component 212 is connected to the end of the roller brush part 23 away from the second connecting part 22, and the connecting arm 211 is connected to the housing component 10. With this configuration, it is not necessary to frequently replace the first connecting part 21 and the second connecting part 22, thus reducing the maintenance cost of this cleaning device. The above configuration enables the first connecting part 21 to achieve a modular design, which facilitates the disassembly and assembly of the first connecting part 21, the housing component 10, and the roller brush part 23.

[0052] Combination Figure 10 and Figure 11 As shown, the housing assembly 10 further includes a first side plate 11 and a second side plate 12 disposed opposite to each other along the axial direction of the roller brush portion 23. The connecting arm 211 of the first connecting portion 21 is detachably disposed on the outer side of the first side plate 11, and the second connecting portion 22 is disposed on the outer side of the second side plate 12. This arrangement facilitates the assembly and disassembly of the connecting arm 211 and the housing assembly 10.

[0053] like Figures 3 to 5As shown, specifically, the roller brush portion 23 has a support hole 2301. The shaft component 212 includes a connecting shaft 2121 and a connecting sleeve 2122. At least a portion of the connecting sleeve 2122 passes through the end of the roller brush portion 23 and is detachably connected to the roller brush portion 23. The connecting shaft 2121 passes through the connecting sleeve 2122 along the axial direction of the roller brush portion 23. One end of the connecting shaft 2121 passes through the support hole 2301, and the other end of the connecting shaft 2121 is fixedly connected to the connecting arm 211. The mating structure of the connecting shaft 2121 and the connecting sleeve 2122 provides a stable rotation axis for the roller brush portion 23, improving the stability of the roller brush portion 23 during rotation. The fact that the connecting shaft 2121 passes through the connecting sleeve 2122 and passes through the support hole 2301 improves the coaxiality between the roller brush portion 23 and the connecting shaft 2121, further enhancing the stability of the roller brush portion 23 during rotation. The connecting sleeve 2122 is detachably connected to the roller brush part 23, which can prevent interference when the roller brush part 23 rotates around the connecting shaft 2121, and improve the stability and smoothness of the rotation of the roller brush part 23.

[0054] In this embodiment, both the connecting shaft 2121 and the connecting sleeve 2122 are injection molded parts. This arrangement reduces the processing cost of the device.

[0055] Furthermore, the connecting shaft 2121 and the connecting arm 211 are connected by injection molding. This arrangement improves the stability of the connection between the connecting shaft 2121 and the connecting arm 211.

[0056] Furthermore, the connecting arm 211 is made of stainless steel. In this embodiment, the thickness of the connecting arm 211 is 1.5mm. This design improves the structural strength of the connecting arm 211, and while ensuring the structural strength of the connecting arm 211, minimizes its thickness, thereby increasing the edge cleaning effect of this cleaning component 20.

[0057] In this embodiment, the connecting shaft 2121 and the connecting arm 211 are connected by injection molding. This configuration improves the stability of the connection between the connecting shaft 2121 and the connecting arm 211.

[0058] Furthermore, a mounting groove is formed between the connecting sleeve 2122 and the connecting shaft 2121. The first connecting part 21 also includes a first bearing 213, which is disposed within the mounting groove and sleeved on the connecting shaft 2121. The inner ring of the first bearing 213 is interference-fitted with the connecting shaft 2121, and the outer ring of the first bearing 213 is interference-fitted with the connecting sleeve 2122. The inclusion of the first bearing 213 improves the smoothness of rotation of the connecting shaft 2121 and the connecting sleeve 2122, and also improves the smoothness of rotation of the roller brush part 23 with the connecting sleeve 2122. Moreover, the fact that the first bearing 213 is located within the mounting groove reduces the possibility of damage to the first bearing 213 due to exposure.

[0059] Furthermore, the connecting sleeve 2122 has a through hole, which includes a first hole segment and a second hole segment sequentially connected along the axial direction of the connecting sleeve 2122. The diameter of the first hole segment is smaller than the diameter of the second hole segment. The connecting shaft 2121 includes a first shaft segment and a second shaft segment sequentially connected along the axial direction. The diameter of the first shaft segment is smaller than the diameter of the second shaft segment. The second shaft segment and the end of the first shaft segment connected to the second shaft segment are located within the second hole segment. The end of the first shaft segment away from the second shaft segment passes through the support hole 2301. A mounting groove is formed between the portions of the first and second shaft segments located within the second hole segment and the connecting sleeve 2122. This arrangement allows the mounting groove to be formed during the assembly process of the connecting sleeve 2122 and the connecting shaft 2121, eliminating the need for separate machining of the mounting groove.

[0060] Furthermore, the roller brush portion 23 includes a roller brush body 231 and a support portion 232; the support portion 232 is disposed within the roller brush body 231, and a support hole 2301 is provided at one end of the support portion 232 facing the connecting sleeve 2122, and the connecting sleeve 2122 is engaged with the support portion 232. In this embodiment, the support portion 232 and the roller brush body 231 are separately disposed and detachably connected. Both the support portion 232 and the roller brush body 231 are injection molded parts. This arrangement can further improve the convenience of processing the support hole 2301 and reduce the processing cost of the roller brush portion 23.

[0061] Specifically, the roller brush body 231 includes a roller 2311 and a cleaning cloth 2312, with the cleaning cloth 2312 wrapped around the outside of the roller 2311.

[0062] In this embodiment of the solution, a snap-fit ​​structure is provided between the support part 232 and the connecting sleeve 2122. The snap-fit ​​structure includes a first snap-fit ​​piece 81 and a second snap-fit ​​piece 82. The first snap-fit ​​piece 81 is disposed on the support part and extends along the axial direction of the roller brush body. The first snap-fit ​​piece 81 is provided with a snap-fit ​​hole 811. The second snap-fit ​​piece 82 is disposed on the connecting sleeve and extends along the axial direction of the roller brush body. The second snap-fit ​​piece 82 is provided with a snap-fit ​​protrusion 821. The snap-fit ​​hole 811 and the snap-fit ​​protrusion 821 are engaged in a snap-fit ​​cooperation.

[0063] Furthermore, multiple snap-fit ​​structures are provided, and these multiple snap-fit ​​structures are distributed at intervals along the circumference of the support portion 232. This arrangement can improve the stability of the connection between the support portion 232 and the connecting sleeve 2122.

[0064] Specifically, the snap-fit ​​protrusion 821 has a hemispherical structure. This design facilitates the snap-fit ​​protrusion 821 to be inserted into or removed from the snap-fit ​​hole 811, thereby improving the ease and smoothness of assembling and disassembling the first snap-fit ​​piece 81 and the second snap-fit ​​piece 82.

[0065] like Figures 1 to 5 As shown, the cleaning device further includes a second drive member 221, and the roller brush section 23 includes a first adapter 233 and a second adapter 234. Both the first adapter 233 and the second adapter 234 are located within the roller brush body 231. The first adapter 233, the second adapter 234, and the support portion 232 are sequentially distributed along the axial direction of the roller brush section 23. The second adapter 234 is detachably connected to both the first adapter 233 and the support portion 232, and the first adapter 233 is detachably connected to the roller brush body 231.

[0066] The first adapter 233 has an anti-rotation hole at its end away from the support 232. The second side plate 12 of the housing assembly 10 also has a mounting hole. The seat of the second drive member 221 is mounted on the second connecting part 22. The end of the second drive member 221 away from the seat passes through the mounting hole, through the second side plate 12, and extends into the roller brush part 23. The output shaft of the second drive member 221 passes through the anti-rotation hole and engages with it to prevent rotation. With this configuration, during cleaning operations, the second drive member 221 drives the first adapter 233 to rotate the roller brush part 23.

[0067] In this embodiment, a second bearing 222 is also provided on the side of the second connecting part 22 facing the second side plate 12. The inner ring of the second bearing 222 is fixedly mounted on the seat of the second driving member 221, and the outer ring of the second bearing 222 passes through the corresponding end of the roller brush part 23 and is interference-fitted with the roller brush part 23. This arrangement facilitates the assembly and disassembly of the roller brush part 23 and the second connecting part 22.

[0068] Furthermore, the cleaning device also includes a magnetic suction part 70, which is disposed on the housing assembly 10, and the first connecting part 21 is magnetically engaged with the magnetic suction part 70. The magnetic suction part 70 improves the ease of assembly and disassembly of the first connecting part 21 and the housing assembly 10.

[0069] Combination Figure 10 As shown, specifically, the magnetic attraction part 70 is disposed on the inner side of the first side plate 11. This arrangement allows the housing assembly 10 to protect the magnetic attraction part 70 and improves the stability of the magnetic attraction between the magnetic attraction part 70 and the first connecting part 21.

[0070] like Figures 6 to 11As shown, the first connecting part 21 and the second connecting part 22 are respectively movably and vertically disposed on the housing assembly 10. The roller brush part 23 is used to abut against the area to be cleaned. The cleaning device also includes a body part 30, a first drive part 40, a detection element 50, and a control element. The body part 30 is rotatably disposed on the housing assembly 10; the first drive part 40 is disposed on the housing assembly 10 and is drivenly connected to the cleaning assembly 20 to make the cleaning assembly 20 move up and down; the detection part of the detection element 50 is disposed at least partially facing the body part 30 to detect the tilt angle of the body part 30, and the detection element 50 is electrically connected to the first drive part 40; the control element is electrically connected to the first drive part 40 and the detection element 50 respectively, and the control element controls the first drive part 40 to drive the cleaning assembly 20 to move up and down according to the tilt angle of the body part 30 relative to the floor brush part detected by the detection element 50.

[0071] Specifically, the housing assembly 10 has a front end and a rear end that are arranged opposite to each other. A wheel 101 is installed at the rear end of the housing assembly 10. The cleaning component 20 is vertically and vertically disposed at the front end of the housing assembly 10, and the bottom of the cleaning component 20 protrudes downward from the bottom of the housing assembly 10. The bottom end of the body component 30 is rotatably disposed at the rear end of the housing assembly 10. When the user operates the cleaning device, the user holds the top end of the body component 30 and tilts it away from the front end of the housing assembly 10.

[0072] The first driving unit 40 includes a first driving member 41 and a pressure plate 42. The first driving member 41 is disposed inside the housing assembly 10, and the pressure plate 42 is disposed vertically inside the housing assembly 10. The first side plate 11 and the second side plate 12 of the housing assembly 10 are respectively provided with clearance holes. The two ends of the pressure plate 42 are respectively inserted into the two clearance holes. The two ends of the pressure plate 42 abut against the top end of the first connecting part 21 and the top end of the second connecting part 22, so as to synchronously drive the first connecting part 21 and the second connecting part 22 to descend.

[0073] In this embodiment, a guide rod is provided inside the housing assembly 10. The guide rod passes through the pressure plate 42 and is guided and cooperates with the pressure plate 42.

[0074] Furthermore, the magnetic suction part 70 is movably disposed on the inner side of the first side plate 11. The magnetic suction part 70 is provided with a sliding hole, and a guide protrusion 111 is provided on the inner side wall of the first side plate 11. The magnetic suction part 70 is disposed on the guide protrusion 111 through the sliding hole and is guided and engaged with the guide protrusion 111. A limiting piece 112 is also provided inside the housing assembly 10. The limiting piece 112 is located on the side of the magnetic suction part 70 away from the first side plate 11 and is engaged with the magnetic suction part 70 to prevent the magnetic suction part 70 from falling off the guide protrusion 111.

[0075] Specifically, when the detection unit 50 detects that the tilt angle of the body component 30 relative to the floor brush component is less than the first preset angle, the control unit controls the first drive unit 40 to drive the cleaning component 20 to move closer to the area to be cleaned in order to increase the friction between the cleaning component 20 and the area to be cleaned.

[0076] This configuration ensures that when the user is using the cleaning device and the tilt angle of the body component 30 relative to the floor brush component is less than a first preset angle, the first drive unit 40 drives the cleaning component 20 to move closer to the area to be cleaned, thereby increasing the friction between the cleaning component 20 and the area to be cleaned and improving the cleaning effect of the cleaning component 20. Specifically, when the body component 30 is in its initial state, the tilt angle of the body component 30 relative to the floor brush component is the first preset angle. At this time, the body component 30 applies the maximum pressure to the floor brush component, and the cleaning component 20 is subjected to the maximum pressure. When the user uses the cleaning device, to improve the comfort of use, the user holds the end of the body component 30 away from the floor brush component to tilt the body component 30. At this time, the user shares some of the weight of the body component 30, the pressure of the body component 30 on the floor brush component is reduced, and the pressure of the cleaning component 20 on the area to be cleaned is reduced. When the detection unit of the detection component 50 detects that the tilt angle of the body component 30 relative to the floor brush component is less than a first preset angle, the detection component 50 transmits the signal to the first drive unit 40. The first drive unit 40 drives the cleaning component 20 to move closer to the area to be cleaned, thereby increasing the friction between the cleaning component 20 and the area to be cleaned and improving the tilting effect of the cleaning component 20. This design, when the tilt angle of the body component 30 relative to the floor brush component is less than the first preset angle (i.e., when the pressure of the body component 30 on the floor brush component decreases), compensates for the pressure between the cleaning component 20 and the area to be cleaned, increasing the friction between the cleaning component 20 and the area to be cleaned, and thus improving the cleaning effect of the cleaning component.

[0077] Specifically, the first preset angle can be determined based on the angle corresponding to the fuselage component 30 in its initial position. The range of the first preset angle can be between 80° and 90° (inclusive).

[0078] Preferably, in the embodiments of this solution, when the body component is in the initial position, the body component 30 and the floor brush component are perpendicular to each other, and the body component 30 has a first preset angle with respect to the floor brush component. The first preset angle is 90 degrees, and the body component 30 applies the maximum force to the floor brush component.

[0079] Furthermore, the cleaning device also includes an elastic portion 60, with its two ends respectively abutting against at least a portion of the housing assembly 10 and the bottom of the cleaning assembly 20 to apply an upward force to the cleaning assembly 20. The elastic portion 60 absorbs some of the impact force during the lifting and lowering of the cleaning assembly 20, improving the smoothness of the lifting and lowering process. Moreover, when the cleaning device is in an idle state, i.e., when the body component 30 is in its initial position, applying an upward force to the cleaning assembly 20 reduces the pressure of the cleaning assembly 20 on the ground, reducing the possibility of damage to the cleaning assembly.

[0080] Furthermore, the body component 30 includes a rotating shaft 31 and is rotatably mounted on the housing assembly 10 via the rotating shaft 31. The rotating shaft 31 has two end faces that are arranged opposite each other along the axial direction. The detection element 50 includes a first sensing part 51 and a second sensing part 52. The first sensing part 51 is disposed on one end face of the rotating shaft 31 and is eccentrically disposed with respect to the rotating shaft 31. The second sensing part 52 is disposed on the housing assembly 10 and is located on the side of the rotating shaft 31 where the end face of the first sensing part 51 is disposed. The second sensing part 52 is in sensory cooperation with the first sensing part 51 and forms the detection part of the detection element 50. When the body component 30 is in the initial position, and the tilt angle between the body component 30 and the floor brush component is a first preset angle, the first sensing part 51 and the second sensing part 52 are directly opposite each other. When the tilt angle between the body component 30 and the floor brush component is less than the first preset angle, the first sensing part 51 and the second sensing part 52 are misaligned.

[0081] Specifically, when the tilt angle of the body component 30 relative to the floor brush component is less than a first preset angle, a sensing signal is triggered between the first sensing unit 51 and the second sensing unit 52, and the first driving unit 40 drives the cleaning assembly 20 to move closer to the area to be cleaned. The rotating shaft 31 enables a rotatable connection between the body component 30 and the housing assembly 10, and the first sensing unit 51 is mounted on the rotating shaft 31 and can rotate synchronously with the rotating shaft 31. When the tilt angle of the body component 30 relative to the floor brush component changes, the relative position between the first sensing unit 51 and the second sensing unit 52 also changes, thereby triggering the corresponding sensing signal.

[0082] Understandably, the rotating shaft 31 extends horizontally and is located at the bottom of the body component 30. The first sensing unit 51 is disposed on the end face of the first end along the axis of the rotating shaft 31, and the second sensing unit 52 is located on the side where the first end along the axis of the rotating shaft 31 is located. This arrangement allows the first sensing unit 51 to be as close as possible to the second sensing unit 52, shortening the transmission path of the sensing signal as much as possible, reducing the possibility of signal interference, and ensuring that the detection unit 50 can quickly and accurately detect the change in the tilt angle of the body component 30 relative to the floor brush component, thereby improving the response speed of the first drive unit 40.

[0083] Specifically, when the tilt angle of the body component 30 relative to the floor brush component is equal to the first preset angle, the first sensing part 51 has the largest projected area on the second sensing part 52 along the axial direction of the rotating shaft 31, and the sensing signal between the first sensing part 51 and the second sensing part 52 is the strongest. At this time, the detection element 50 recognizes that the body component 30 is in the initial state. When the tilt angle of the body component 30 relative to the floor brush component gradually decreases, the projected area of ​​the first sensing part 51 on the second sensing part 52 gradually decreases along the axial direction of the rotating shaft 31, and the sensing signal between the first sensing part 51 and the second sensing part 52 gradually weakens. At this time, the detection element 50 recognizes that the body component 30 is gradually tilting, and the force applied by the first drive part 40 to the cleaning assembly 20 in the direction of the area to be cleaned gradually increases. This setting ensures that the less pressure the body component 30 exerts on the floor brush component, the stronger the pressure applied by the first drive part 40 to the cleaning assembly 20, further improving the cleaning effect of the device.

[0084] It is understandable that when the tilt angle of the body component 30 relative to the floor brush component is equal to the first preset angle, the cleaning component 20 is in the upper limit position.

[0085] In this embodiment, when the sensing signal between the first sensing unit 51 and the second sensing unit 52 is the weakest, the tilt angle between the body component 30 and the floor brush component is the third preset angle. At this time, the body component 30 is in the extreme tilt position, and the cleaning component 20 is in the lower extreme position.

[0086] The third preset angle can be set to 0 degrees.

[0087] Similarly, conversely, as the tilt angle of the body component 30 relative to the floor brush component gradually increases from the third preset angle to the first preset angle, the sensing signal between the first sensing unit 51 and the second sensing unit 52 gradually increases, and the force exerted by the first driving unit 40 on the cleaning component 20 in the direction of the area to be cleaned gradually decreases until the body component 30 is in a vertical state, the cleaning component 20 is in the upper limit position, and the first driving unit 40 no longer exerts a force on the cleaning component 20.

[0088] Furthermore, the first sensing unit 51 is a magnetic signal generating element, and the second sensing unit 52 is a magnetic signal detecting element 50.

[0089] The first sensing part 51 can be configured as a magnet, and the second sensing part 52 can be configured as a Hall sensor.

[0090] like Figure 12 As shown, Embodiment 2 of this utility model provides a cleaning device, which differs from Embodiment 1 in that...

[0091] This utility model embodiment two also provides a cleaning device, which differs from embodiment one in that the detection element 50 in this embodiment includes a first sensing part 51, a second sensing part 52, and a third sensing part 53. The third sensing part 53 and the first sensing part 51 are distributed at intervals along the circumference of the rotating shaft 31. The third sensing part 53 is disposed at the end of the first end in the axial direction of the rotating shaft 31, and the second sensing part 52 is in sensory engagement with the third sensing part 53.

[0092] The third sensing unit 53 is a magnetic signal generating device, which can be specifically configured as a magnet.

[0093] When the tilt angle of the body component 30 relative to the floor brush component is equal to the first preset angle, the first sensing part 51 has the largest projected area on the second sensing part 52 along the axis of the rotating shaft 31, and the sensing signal between the first sensing part 51 and the second sensing part 52 is the strongest. At this time, the detection element 50 recognizes that the body component 30 is in the initial state. When the tilt angle of the body component 30 relative to the floor brush component gradually decreases, the projected area of ​​the first sensing part 51 on the second sensing part 52 gradually decreases along the axis of the rotating shaft 31, and the sensing signal between the first sensing part 51 and the second sensing part 52 gradually weakens. At this time, the detection element 50 recognizes that the body component 30 gradually tilts, and the force applied by the first driving part 40 to the cleaning component 20 in the direction of the area to be cleaned gradually increases until the tilt angle of the body component 30 relative to the floor brush component is equal to the second preset angle. If the tilt angle of the body component 30 relative to the floor brush component remains at the second preset angle, the force applied by the first driving part 40 to the cleaning component 20 remains unchanged, that is, the position of the cleaning component 20 relative to the housing component 10 remains unchanged.

[0094] When the tilt angle of the body component 30 relative to the floor brush component is less than the second preset angle, the sensing signal between the first sensing unit 51 and the second sensing unit 52 disappears, the sensing signal between the third sensing unit 53 and the second sensing unit 52 is triggered, and the first driving unit 40 drives the cleaning component 20 to continue moving towards the area to be cleaned, wherein the second preset angle is less than the first preset angle.

[0095] In this embodiment of the solution, when the sensing signal between the first sensing unit 51 and the second sensing unit 52 disappears, the first driving unit 40 drives the cleaning component 20 to move downward to an intermediate position between the upper limit position and the lower limit position, which is the same distance from the upper limit position and the lower limit position.

[0096] Specifically, when the tilt angle of the body component 30 relative to the floor brush component is equal to the second preset angle, the third sensing part 53 has the smallest projected area on the second sensing part 52 along the axial direction of the rotating shaft 31, and the sensing signal between the third sensing part 53 and the second sensing part 52 is the weakest; when the tilt angle of the body component 30 relative to the floor brush component gradually decreases, the projected area of ​​the third sensing part 53 on the second sensing part 52 gradually increases along the axial direction of the rotating shaft 31, the sensing signal between the third sensing part 53 and the second sensing part 52 gradually increases, and the force applied by the first driving part 40 to the cleaning assembly 20 in the direction of the area to be cleaned gradually increases.

[0097] In this embodiment of the solution, when the tilt angle of the body component 30 relative to the floor brush component is equal to the third preset angle, the third sensing part 53 has the largest projected area on the second sensing part 52 along the axial direction of the rotating shaft 31, the sensing signal between the third sensing part 53 and the second sensing part 52 is the strongest, and the cleaning component 20 is in the lower limit position.

[0098] The first preset angle can be set to 90 degrees, the third preset angle can be set to 0 degrees, and the second preset angle can be set to 45 degrees.

[0099] This solution, through the sequential sensing cooperation between the first sensing unit 51 and the third sensing unit 53 and the second sensing unit 52, can further improve the signal sensing accuracy between the second sensing unit 52 and the first sensing unit 51, as well as the signal sensing accuracy between the second sensing unit 52 and the third sensing unit 53, thereby further improving the cleaning effect of the device.

[0100] Similarly, conversely, as the tilt angle of the body component 30 relative to the floor brush component gradually increases from the third preset angle to the first preset angle, the sensing signal between the third sensing unit 53 and the second sensing unit 52 gradually decreases, and the force exerted by the first drive unit 40 on the cleaning assembly 20 in the direction of the area to be cleaned gradually decreases; when the tilt angle of the body component 30 relative to the floor brush component increases to the second preset angle, the sensing signal between the third sensing unit 53 and the second sensing unit 52 is at its minimum; when the tilt angle of the body component 30 relative to the floor brush component exceeds the second preset angle, the second sensing unit 52 senses the signal of the first sensing unit 51, the sensing signal between the second sensing unit 52 and the third sensing unit 53 disappears, and the force exerted by the first drive unit 40 on the cleaning assembly in the direction of the area to be cleaned continues to gradually decrease until the body component 30 is in a vertical state, the cleaning assembly 20 is in the upper limit position, and the first drive unit 40 no longer exerts a force on the cleaning assembly 20.
