[0046] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0047] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, inside, outside, top, bottom, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0048] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0049] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0050] With the advancement of science and technology, smart home appliances have also developed rapidly. For example, the cleaning equipment developed can help people clean the floor, greatly reducing the labor intensity and time of people's cleaning. Some cleaning equipment, such as sweeping robots, will be equipped with cleaning components such as rollers at the bottom of the main body of the equipment. When the cleaning equipment moves, it can drive the cleaning components to move, and the cleaning components can clean the floor.

[0051] Some cleaning equipment will have a lifting assembly installed on the main body of the equipment, and the cleaning assembly is connected to the lifting assembly. When the cleaning equipment passes over a carpet or a floor that has been cleaned, the cleaning assembly is lifted by the lifting assembly to prevent the cleaning assembly from wetting the carpet or contaminating the cleaned floor. In the related art, the lifting assembly includes a driving mechanism and a cable, one end of the cable is connected to the driving mechanism, and the other end is connected to the cleaning assembly. The driving mechanism drives the cleaning assembly to rise and fall through the cable.

[0052] However, it was found during use that when the cleaning component is heavier when it absorbs water, the driving mechanism encounters greater resistance when controlling the lifting and lowering of the cleaning component through cables, which can easily damage the driving mechanism. For example, when the driving mechanism includes a motor, if the motor encounters too much resistance, the motor is prone to stalling, causing damage to the motor.

[0053] Therefore, the utility model provides a cleaning device, which can effectively improve the above problems.

[0054] Reference below Figures 1 to 15 A cleaning device according to an embodiment of the present invention is described.

[0055] like Figure 1 and Fig.15 As shown, the cleaning device according to the embodiment of the utility model includes a device body 100 , a bracket 200 , a cleaning assembly 300 , a lifting assembly 400 and a pulley assembly 500 .

[0056] For example, the device body 100 may be in a disc shape, a square disc shape, or other suitable shapes, and running wheels may be installed at the bottom of the device body 100, and the running wheels are used to drive the cleaning device to move.

[0057] The bracket 200 is movably disposed on the device body 100, and the bracket 200 has a lifting stroke. When the bracket 200 rises to a first position, it is located at the top of the lifting stroke and cannot continue to rise. When the bracket 200 descends to a second position, it is located at the bottom of the lifting stroke and cannot continue to descend. The bracket 200 may be provided with a mounting seat 310, and the mounting seat 310 may be provided with a mounting cavity 311 with an opening facing downward.

[0058] The cleaning component 300 can be arranged in the mounting cavity 311 of the mounting seat 310. The cleaning component 300 can be a roller, a roller brush, a crawler cloth, a cleaning nozzle or other suitable cleaning components. Taking the cleaning component 300 as a roller as an example, the cleaning component 300 can be horizontally installed at the bottom end of the equipment body 100, that is, the axial direction of the cleaning component 300 extends in the horizontal direction, and the cleaning component 300 can rotate around its own axis.

[0059] The lifting assembly 400 can be arranged at a suitable position on the device body 100. The lifting assembly 400 includes a driving mechanism 410 and a cable 420. The cable 420 can be a steel wire rope, a nylon rope or other suitable flexible ropes. Of course, the cable 420 can also be a chain.

[0060] The pulley assembly 500 includes a first movable pulley 501, which is disposed on the bracket 200. The rotation axis of the first movable pulley 501 can extend along the water direction. The cable 420 is wound around the first movable pulley 501, for example, it can be wound around the bottom end of the first movable pulley 501. One end of the cable 420 can be transmission-connected to the driving mechanism 410, and the other end of the cable 420 can be connected to the device body 100. The driving mechanism 410 controls the lifting and lowering of the bracket 200 through the cable 420.

[0061] When the driving mechanism 410 is started, the driving mechanism 410 can control the lifting of the bracket 200 through the cable 420, thereby driving the cleaning assembly 300 to lift.

[0062] According to the cleaning device of the embodiment of the utility model, since the bracket 200 is provided with a first movable pulley 501, the end of the cable 420 away from the driving mechanism 410 is wound around the first movable pulley 501 and then connected to the device body 100, rather than being directly connected to the bracket 200, and thus the driving mechanism 410 only needs to bear half of the weight of the cleaning component 300 and the bracket 200 as a whole, and the other half of the weight is borne by the device body 100, thereby reducing the resistance experienced by the driving mechanism 410, and providing the first movable pulley 501 can reduce the friction experienced by the cable 420, thereby further reducing the resistance experienced by the driving mechanism 410, thereby avoiding damage caused by excessive resistance experienced by the driving mechanism 410, and can also reduce the torque required to be output by the driving mechanism 410.

[0063] It should be noted that the number of the first movable pulleys 501 may be one or more. When there are more than one first movable pulleys 501 , the cable 420 may be wound around the more than one first movable pulleys 501 .

[0064] refer to Figure 3As shown, in some embodiments of the present invention, the pulley assembly 500 further includes a second movable pulley 502 and a fixed pulley 503, the second movable pulley 502 is provided on the bracket 200, the fixed pulley 503 is provided on the device body 100, and the cable 420 is led out from the driving mechanism 410 and is sequentially wound around the first movable pulley 501, the fixed pulley 503, and the second movable pulley 502. For example, one end of the cable 420 away from the driving mechanism 410 may be sequentially wound around the bottom end of the first movable pulley 501, the top end of the fixed pulley 503, and the bottom end of the second movable pulley 502, and then connected to the device body 100.

[0065] In this embodiment, the cable 420 can be divided into a first section and a second section, the first movable pulley 501 is carried on the first section, one end of the first section is connected to the driving mechanism 410, and the other end is wound around the fixed pulley 503 on the device body 100, and the second movable pulley 502 is carried on the second section, one end of the second section is connected to the device body 100, and the other end is wound around the fixed pulley 503 on the device body 100 and connected to the first section. In this way, the overall weight of the bracket 200 and the cleaning component 300 is borne by both ends of the first section and the second section of the cable 420, and only one end of the first section connected to the driving mechanism 410 acts on the driving mechanism 410, and the other end of the first section and both ends of the second section act directly or indirectly on the device body 100. In this way, the driving mechanism 410 only needs to bear 1 / 4 of the overall weight of the bracket 200 and the cleaning component 300, and then the driving force required to be provided by the driving mechanism 410 is greatly reduced, which is not only more convenient to drive, but also less prone to damage.

[0066] It should be noted that the pulley assembly 500 can also be provided with more pulleys on the bracket 200 and the device body 100, which will not be described in detail here.

[0067] refer to Figure 3 As shown, in a further embodiment of the present invention, the second movable pulley 502 may be located above the first movable pulley 501, and the fixed pulley 503 may be located above the second movable pulley 502. In this way, the pulling force provided by the cable 420 to the first movable pulley 501 and the second movable pulley 502 is generally upward, while the overall gravity of the bracket 200 and the cleaning assembly 300 applied to the first movable pulley 501 and the second movable pulley 502 is downward, and then according to the force balance condition, the pulling force required to be provided by the cable 420 is minimal, so that the driving force required to be provided by the driving mechanism 410 is smaller, which is not only more convenient to drive, but also less prone to damage.

[0068] It should be noted that the first movable pulley 501 , the second movable pulley 502 and the fixed pulley 503 may also have other suitable positional relationships. For example, the first movable pulley 501 and the second movable pulley 502 may also be located below both sides of the fixed pulley 503 .

[0069] refer to Figures 4 to 9 As shown, in some embodiments of the utility model, the lifting assembly 400 also includes a cable storage component 430, the driving mechanism 410 is provided with a rotatable driving part 411, the cable storage component 430 is detachably connected to the driving part 411 and is driven to rotate by the driving part 411, and the cable 420 is connected to and rolled up on the cable storage component 430, wherein, when the driving mechanism 410 drives the bracket 200 to rise from the second position to the first position and the driving mechanism 410 continues to run, the cable storage component 430 is separated from the driving part 411.

[0070] For example, the cable storage member 430 may be in the shape of a disk, and the cable storage member 430 may rotate around its own axis. The outer wall of the cable storage member 430 may be provided with a winding groove 432, and one end of the cable 420 is connected to the cable storage member 430 and wound in the winding groove 432. The cable storage member 430 is connected to the driving part 411. When the force applied by the cable 420 to the cable storage member 430 is too large, the cable storage member 430 is separated from the driving part 411. When the driving mechanism 410 is started, the driving mechanism 410 can drive the driving part 411 to rotate, and the driving part 411 can drive the cable storage member 430 to rotate synchronously, so that the cable 420 can be rolled up on the cable storage member 430 or unfolded from the cable storage member 430, so that the driving mechanism 410 drives the bracket 200 and the cleaning component 300 to rise and fall.

[0071] In this embodiment, when the cleaning component 300 rises from the second position to the first position, that is, rises to the top of the stroke, it cannot continue to rise, and the cable 420 cannot continue to be reeled into the cable storage member 430. At this time, if an operating error or equipment failure occurs, causing the driving mechanism 410 to continue to operate, the force applied by the cable 420 to the cable storage member 430 will be greatly increased, and then the interaction force between the cable storage member 430 and the driving part 411 will be greatly increased, which will cause the cable storage member 430 to separate from the driving part 411. In this case, the driving mechanism 410 does not need to drive the cable storage member 430, the cable 420, the bracket 200 and the cleaning component 300, but only drives the driving part 411 to rotate, thereby significantly reducing the resistance encountered by the driving mechanism 410, thereby avoiding damage to the driving mechanism 410 due to excessive resistance.

[0072] It should be noted that the utility model mentions that when the cleaning component 300 rises to the first position, the driving mechanism 410 continues to operate, which will greatly increase the force applied by the cable 420 to the cable storage member 430, which means that the bracket 200 has an upward trend, rather than driving the bracket 200 to descend.

[0073] It is understandable that the cable storage member 430 can be a reel, a reel or other suitable structure, as long as it can reel in the cable 420, which will not be described in detail here. There are many types of drive mechanism 410. For example, it can only include a motor 413, the output shaft of the motor 413 is directly coaxially connected to the drive unit 411, and the drive mechanism 410 directly controls the rotation of the drive unit 411. In addition, the drive mechanism 410 can also include a motor 413 and a reducer connected to the motor 413, and the drive mechanism 410 indirectly controls the rotation of the drive unit 411 through the reducer. The motor 413 can be a progressive motor, a servo motor or other suitable types of motors 413. When the drive mechanism 410 includes a motor 413, if the resistance applied to the motor 413 by the cable storage member 430 is too large, the motor 413 is prone to stalling, thereby causing damage to the motor 413. In addition, the motor 413 can also be replaced with a structure such as a rotating cylinder that can drive the drive unit 411 to rotate.

[0074] When a reducer is provided between the motor 413 and the driving unit 411, the reducer can be provided as follows: Figure 2 and Figure 3 In the structure shown, specifically, the outer wall of the driving part 411 is provided with an outer gear ring along the circumferential direction, the output shaft of the motor 413 is coaxially connected with the worm 414, and the lifting assembly 400 may also include a mounting part 440, the mounting part 440 may be rotatably mounted with a gear shaft 443, the gear shaft 443 is coaxially mounted with a worm wheel 415 meshing with the worm 414, the gear shaft 443 is also coaxially mounted with a transmission gear 416, and the transmission gear 416 is meshed with the driving part 411. When the motor 413 is started, the motor 413 can drive the worm 414 to rotate, and the worm 414 thereby drives the worm wheel 415 to rotate, and the worm wheel 415 can drive the transmission gear 416 to rotate through the gear shaft 443, and the transmission gear 416 thereby drives the driving part 411 to rotate.

[0075] refer to Figures 4 to 9 As shown, in some embodiments of the present invention, the lifting assembly 400 further includes a mounting portion 440 and an elastic member 450 .

[0076] For example, the mounting portion 440 may be a box structure, the mounting portion 440 having an inner cavity for mounting the cable storage component 430, the driving portion 411 and the elastic component 450, the mounting portion 440 may be provided with a hole for the cable 420 to pass through, and the outer wall of the mounting portion 440 may be provided with a plurality of connecting portions 442, and the connecting portions 442 are used to install fasteners between the device body 100.

[0077] The cable storage member 430 can be installed in the inner cavity of the installation portion 440 . The cable storage member 430 can move along its own axial direction. One or more protrusions 431 can be provided on the end surface of the cable storage member 430 close to the driving portion 411 .

[0078] The driving part 411 of the driving mechanism 410 can be installed in the inner cavity of the mounting part 440. One or more recesses 412 can be provided on the end surface of the driving part 411 close to the cable storage part 430. The protrusion 431 on the cable storage part 430 is engaged and clamped in the corresponding recess 412 on the driving part 411, so that when the driving part 411 rotates, it can drive the cable storage part 430 to rotate synchronously.

[0079] The elastic member 450 can be installed on the mounting portion 440 and located on the side of the cable storage member 430 away from the driving portion 411. The end of the elastic member 450 close to the cable storage member 430 can elastically abut against the end of the cable storage member 430 away from the driving portion 411, and the end of the elastic member 450 away from the cable storage member 430 can elastically abut against the inner wall of the mounting portion 440 or be directly connected to the mounting portion 440. The elastic member 450 can apply elastic pressure to the cable storage member 430, so that the convex portion 431 can be kept in a state of being clamped in the concave position 412, thereby preventing the cable storage member 430 from being separated from the driving portion 411 at will, so that the driving portion 411 can drive the cable storage member 430 to rotate synchronously with a better effect. When the cleaning component 300 rises to the first position, if an operating error or equipment failure occurs that causes the driving mechanism 410 to continue to operate, the force applied by the cable 420 to the cable storage member 430 will be greatly increased, and this force can offset the elastic pressure applied by the elastic member 450 and the interaction force between the protrusion 431 and the recessed position 412, thereby enabling the protrusion 431 to slide out of the corresponding recessed position 412, thereby enabling the cable storage member 430 to be separated from the driving member 411. The structure is simple, and the cable storage member 430 and the driving member 411 are separated very conveniently and quickly, and the cable storage member 430 and the driving member 411 are also very convenient to connect after being separated.

[0080] It should be noted that the end surface of the driving portion 411 close to the cable storage member 430 may be provided with a convex portion 431 , and the end surface of the cable storage member 430 close to the driving portion 411 may be provided with a concave portion 412 . In addition, the cable storage component 430 and the driving part 411 can also be connected in other ways. For example, the outer wall of one of the cable storage component 430 and the driving part 411 can be provided with an external thread, and the other can be provided with a threaded hole. The cable storage component 430 and the driving part 411 are threadedly connected through the matching threaded hole and the external thread. There can be a large friction resistance between the cable storage component 430 and the driving part 411. When the circumferential force applied by the cable 420 to the cable storage component 430 is small, the cable storage component 430 and the driving part 411 will not rotate relative to each other, and the driving part 411 can then drive the cable storage component 430 to rotate synchronously. When the circumferential force applied by the cable 420 to the cable storage component 430 is too large, that is, greater than the friction resistance between the cable storage component 430 and the driving part 411, the cable storage component 430 and the driving part 411 can rotate relative to each other, thereby separating the cable storage component 430 from the driving part 411.

[0081] refer to Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the mounting portion 440 is provided with a mounting shaft 441 , the cable storage member 430 is rotatably sleeved outside the mounting shaft 441 and can slide along the axial direction of the mounting shaft 441 , and the driving portion 411 is rotatably mounted on the mounting shaft 441 .

[0082] For example, both ends of the mounting shaft 441 can be rotatably connected to the mounting portion 440, the cable storage member 430 is provided with a first set of holes and is sleeved on the outside of the mounting shaft 441 through the first set of holes, the cable storage member 430 can rotate around the axis of the mounting shaft 441, and can slide along the axial direction of the mounting shaft 441, the driving portion 411 can be provided with a second set of holes and is sleeved on the outside of the mounting shaft 441 through the second set of holes, and the driving portion 411 does not slide along the axial direction of the mounting shaft 441. In this embodiment, the installation shaft 441 is provided, which can realize the rotational installation of the cable storage member 430 and the driving portion 411, and can also realize the axial movement of the cable storage member 430, which is a clever design.

[0083] It should be noted that the driving part 411 may not be sleeved outside the mounting shaft 441, but may be fixedly connected to the mounting shaft 441. In this case, the mounting shaft 441 may be arranged to be rotatably mounted on the mounting part 440. In addition, the mounting shaft 441 may not be arranged, and the cable storage part 430 and the driving part 411 may be installed in other ways. For example, a mounting hole may be arranged on the mounting part 440, and the end of the cable storage part 430 away from the driving part 411 may be fitted in the mounting hole, and the outer wall of the end of the cable storage part 430 away from the driving part 411 may be fitted with the inner wall of the mounting hole, and the cable 420 may be wound around the outer wall of the end of the cable storage part 430 close to the driving part 411, and the cable storage part 430 may be rotatable and slidable along the axial direction of the mounting hole. In this case, the driving part 411 may be rotatably mounted on the mounting part 440 by a single axis.

[0084] refer to Figure 5 and Figure 6 As shown, in a further embodiment of the present invention, the elastic member 450 includes a spring sleeved outside the mounting shaft 441. For example, one end of the spring can elastically abut against the end surface of the cable storage member 430 that is away from the driving portion 411, and the other end of the spring can abut against the inner wall of the mounting portion 440 or be directly connected to the mounting portion 440. In this embodiment, the elastic member 450 is configured as a spring, which has high structural strength, long service life, and good elastic effect, thereby achieving a better elastic abutment effect on the cable storage member 430. In addition, the spring can be installed by sleeved outside the mounting shaft 441, which is convenient to install.

[0085] It should be noted that the elastic member 450 may also be other structures, for example, it may be an elastic rubber block or a metal spring, and it only needs to be able to elastically abut the end surface of the cable storage member 430 that is away from the driving part 411 so that the protrusion 431 can remain in a state of being clamped in the recess 412.

[0086] refer to Figure 7 and Figure 8As shown, in some embodiments of the present invention, a plurality of recesses 412 are provided and are evenly arranged along the circumference of the mounting shaft 441, and a plurality of convex portions 431 are provided corresponding to the recesses 412 and are evenly arranged along the circumference of the mounting shaft 441. For example, six recesses 412 may be provided, and the six recesses 412 are evenly arranged along the circumference of the mounting shaft 441, and six convex portions 431 may be provided, and the six convex portions 431 are evenly arranged along the circumference of the mounting shaft 441. In this embodiment, such a configuration not only makes the connection between the cable storage member 430 and the driving part 411 more stable, and then the driving part 411 drives the cable storage member 430 to rotate more smoothly, but also when one of the convex portions 431 is aligned with one of the recesses 412, the other convex portions 431 are also aligned with the other corresponding recesses 412, so that all the convex portions 431 are conveniently inserted into the corresponding recesses 412.

[0087] It is understandable that the number of the concave portions 412 and the convex portions 431 may be other suitable numbers, for example, three, four or five.

[0088] refer to Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the surface of the concave position 412 is set to be a concave spherical surface or arc surface, and the surface of the convex portion 431 is set to be a convex spherical surface or arc surface. For example, when the surface of the concave position 412 is set to be a concave spherical surface, the surface of the convex portion 431 is set to be a convex spherical surface, and when the surface of the concave position 412 is set to be a concave arc surface, the surface of the convex portion 431 is set to be a convex arc surface. In this embodiment, such a configuration allows the convex portion 431 to slide into or out of the concave position 412, and the sliding is smoother, which can avoid the occurrence of a stuck phenomenon.

[0089] refer to Figure 4 , Figure 5 and Fig. 9 As shown, in some embodiments of the present invention, a protective sleeve 421 is provided on the outer cover of the cable 420. The protective sleeve 421 can not only protect the cable 420 and prevent the cable 420 from being exposed to the outside and damaged, but also reduce the friction between the cable 420 and the protective sleeve 421, thereby reducing the wear of the cable 420 and the wear of other parts of the cleaning device by the cable 420. In addition, the cable 420 can move more smoothly to avoid jamming.

In this embodiment, such a configuration is not only convenient for installing the cable 420, but also convenient for replacing the cable 420 when the cable 420 is damaged.

[0091] refer to Figure 2 and Fig.15 As shown, in some embodiments of the utility model, the device body 100 is provided with a swing frame 110 that can rotate relative to the device body 100, the rotation axis between the swing frame 110 and the device body 100 extends in the horizontal direction, and the bracket 200 is connected to the swing frame 110. Through the swing of the swing frame 110, it is convenient for the cable 420 to drive the bracket 200 to rise and fall. In addition, since the cable 420 is a flexible member, when the cleaning component 300 passes through an uneven ground or obstacle, it is subjected to the force applied by the uneven ground or obstacle, and the bracket 200 can also passively float along the height direction of the device body 100 with the swing of the swing frame 110, so that the cleaning component 300 can smoothly pass through the uneven ground or obstacle, thereby improving the cleaning effect and efficiency.

[0092] refer to Figure 2 and Fig.15 As shown, in a further embodiment of the utility model, the swing frame 110 includes a plurality of swing rods 111 rotatably connected to the device body 100 and parallel to each other, the rotation axes between all the swing rods 111 and the device body 100 extend in the horizontal direction and are coplanar, and the bracket 200 is connected to one end of all the swing rods 111 away from the device body 100.

[0093] For example, the lengths of all the swing rods 111 can be equal, the number of the swing rods 111 can be two, four, six, eight or other suitable numbers, a first mounting block can be provided on the device body 100 corresponding to the swing rod 111, and a second mounting block can be provided on the bracket 200 corresponding to the swing rod 111, one end of the swing rod 111 is installed on the first mounting block, and the other end is installed on the second mounting block.

[0094] In this embodiment, the rotation axes between all the swing rods 111 and the device body 100 extend in the horizontal direction and are coplanar, so that all the swing rods 111 can swing synchronously, thereby driving the bracket 200 to float along the height direction of the device body 100. The structure is simple and the swing frame 110 has a high structural strength. In addition, the installation of the bracket 200 is more stable.

[0095] It should be noted that in some other embodiments of the present invention, the swing frame 110 may also be other structures, for example, it may be an integral structure, and the swing frame 110 is rotatably connected to the device body 100 via a rotating shaft, and the rotating shaft may extend in the horizontal direction.

[0096] refer to Figure 2 and Fig.15 As shown, in a further embodiment of the utility model, there are at least two groups of swing rods 111 distributed side by side, and each group of swing rods 111 is arranged with at least two swing rods 111 along the height direction of the device body 100, all the swing rods 111 are rotatably connected to the bracket 200, and the rotation axes between all the swing rods 111 and the bracket 200 extend in the horizontal direction and are coplanar.

[0097] For example, two groups of swing rods 111 can be distributed side by side, and the two groups of swing rods 111 can be arranged along the extension direction of the rotation axis between the swing rod 111 and the device body 100. The two groups of swing rods 111 are respectively located on both sides of the bracket 200. Each group of swing rods 111 can include two swing rods 111 arranged vertically. The two swing rods 111 in the same group, the corresponding first mounting blocks and the corresponding second mounting blocks form a parallel four-bar linkage mechanism, and the rotation axis between the swing rod 111 and the bracket 200 is parallel to the rotation axis between the swing rod 111 and the device body 100.

[0098] In this embodiment, the same group of swing rods 111 are arranged vertically, and the rotation axes between all the swing rods 111 and the bracket 200 extend in the horizontal direction and are coplanar, so that during the swinging of the swing frame 110, the angle of the bracket 200 relative to the horizontal plane can remain unchanged without deflecting relative to the horizontal plane, so that the mounting cavity 311 of the mounting seat 310 can always face downward, so that when cleaning the cleaning component 300, it is convenient to discharge dirty water and garbage on the cleaning component 300. In addition, it can also prevent the bracket 200 from deflecting relative to the horizontal plane and interfering with the ground or obstacles, thereby avoiding affecting the movement of the cleaning equipment and avoiding damage to the bracket 200, the ground or obstacles.

[0099] It should be noted that the swing rods 111 may be arranged side by side in three, four, five or other suitable numbers, and each group of swing rods 111 may be arranged vertically in three, four, five or other suitable numbers.

[0101] For example, the first switch 120 and the second switch 130 can both be arranged on the device body 100. When the driving mechanism 410 is provided with a motor 413, the first switch 120 and the second switch 130 are both electrically connected or communicatively connected to the motor 413.
