Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, specifically to a cleaning component and cleaning equipment. Background Technology

[0002] In related technologies, cleaning components of cleaning equipment are used to sweep the objects to be cleaned in the area to be cleaned into the cleaning path of the cleaning equipment to improve cleaning coverage and work efficiency. However, after the cleaning components clean the area to be cleaned, the cleaning body will carry the objects to be cleaned, water stains, etc. When the cleaning equipment moves to the carpet, the objects to be cleaned and water stains on the cleaning body will stick to the carpet, causing the carpet to be contaminated. Utility Model Content

[0003] In view of the above problems, this application provides a cleaning component and cleaning equipment to solve the technical problems of cleaning objects, water stains and other contaminants on carpets in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is conceived as follows:

[0005] In a first aspect, this application provides a cleaning component, comprising: a transmission mechanism; a first housing, sleeved outside the transmission mechanism and rotating in a horizontal plane as the transmission mechanism rotates; and a mounting bracket, one end of which is used to mount the cleaning body, the other end of which is disposed inside the first housing, the middle part of which is movably connected to the first housing. When the first housing rotates in a horizontal plane, the mounting bracket can rotate relative to the first housing in both a horizontal and a vertical plane simultaneously, thereby enabling the cleaning body to move up and down towards the end of the surface to be cleaned.

[0006] The mounting bracket has a first limiting part at one end; the cleaning component also includes a limiting rod with a second limiting part, which is movably connected to the first limiting part, and the first limiting part can move vertically relative to the second limiting part; when the first housing rotates in the horizontal plane, it drives the mounting bracket to rotate in both the horizontal and vertical planes relative to the limiting rod, thereby achieving the lifting and lowering of one end of the mounting bracket.

[0007] The first housing is provided with a locking part, which is used to lock the mounting bracket to prevent the mounting bracket from rotating in the vertical plane; when the locking part locks the mounting bracket, the mounting bracket and the limiting rod rotate in the horizontal plane.

[0008] The first housing has a cavity and an opening communicating with the cavity. At least a portion of the mounting bracket is located inside the opening, with one end of the mounting bracket located outside the first housing and the other end of the mounting bracket located inside the cavity. The inner wall of the opening serves as a locking part to limit the rotation angle of the mounting bracket in the vertical plane, thereby limiting the lifting range of the mounting bracket.

[0009] The lower inner wall of the opening is provided with a first inclined surface, and the height of the first inclined surface gradually decreases from the side closer to the cavity to the side farther away from the cavity; the upper inner wall of the opening is provided with a second inclined surface, and the height of the second inclined surface gradually increases from the side closer to the cavity to the side farther away from the cavity; the inclination angle of the second inclined surface relative to the horizontal plane is smaller than the inclination angle of the first inclined surface relative to the horizontal plane.

[0010] The transmission mechanism is configured with a forward rotation mode and a reverse rotation mode. In the forward rotation mode, the first housing rotates clockwise in the horizontal plane, the first limiting part moves downward in the vertical direction relative to the second limiting part, and one end of the mounting bracket moves upward relative to the limiting rod until the mounting bracket is limited by the second inclined surface. In the reverse rotation mode, the first housing rotates counterclockwise in the horizontal plane, the first limiting part moves upward in the vertical direction relative to the second limiting part, and one end of the mounting bracket moves downward relative to the limiting rod until the mounting bracket is limited by the first inclined surface.

[0011] The limiting rod includes a screw that extends vertically, a second limiting part that is the threaded tooth of the screw, and a first limiting part that is a tooth that matches the threaded tooth.

[0012] The cleaning component also includes a damping component, which is sleeved on the end of the limiting rod away from the second limiting part, and is configured to prevent the limiting rod from rotating in the horizontal plane relative to the first housing when the mounting bracket moves in the vertical direction relative to the limiting rod.

[0013] The cleaning component also includes: a second housing, with the end of the transmission mechanism away from the first housing movably connected to the second housing; and a hovering recognition mechanism, disposed on the second housing, for recognizing the rotation angle of the transmission mechanism and generating a hovering signal when the rotation angle is a preset angle, the hovering signal being used to control the transmission mechanism to stop transmission.

[0014] The hovering recognition mechanism includes: an optical coupler disposed on the second housing; and a rotating block connected to the transmission mechanism and rotating in the horizontal plane as the transmission mechanism rotates. When the light-shielding part of the rotating block rotates into the optical path of the optical coupler, the optical coupler generates a hovering signal. The position of the rotating block in the circumferential direction of the transmission mechanism corresponds to the position of the mounting bracket in the circumferential direction.

[0015] The cleaning components also include a cleaning body, which is installed at one end of the mounting bracket.

[0016] Secondly, this application provides a cleaning device, which includes: a device body with a drive mechanism; and the aforementioned cleaning component, which is disposed on the device body and whose transmission mechanism is connected to the drive mechanism.

[0017] The advantages of this application's implementation, unlike existing technologies, are as follows: This application provides a cleaning component and cleaning equipment. The cleaning component includes a transmission mechanism, a first housing, and a mounting bracket. The first housing is sleeved outside the transmission mechanism and rotates horizontally with the rotation of the transmission mechanism. One end of the mounting bracket is used to mount the cleaning body, and the other end of the mounting bracket is disposed inside the first housing. The middle part of the mounting bracket is movably connected to the first housing. When the first housing rotates horizontally, the mounting bracket can rotate relative to the first housing in a vertical plane, thereby achieving the lifting and lowering of the cleaning body near the surface to be cleaned. When the transmission mechanism drives the first housing to rotate horizontally, it drives the mounting bracket to rotate relative to the first housing in a vertical plane, enabling the lifting and lowering of one end of the mounting bracket. The lifting and lowering of one end of the mounting bracket can drive the lifting and lowering of the cleaning body. Therefore, for example, when the cleaning equipment is about to be moved onto the carpet, the drive transmission mechanism can be rotated to lift the cleaning body by the mounting frame, reducing or preventing the carpet from being contaminated by the cleaning items, water stains, etc. on the cleaning body when the cleaning equipment is moved onto the carpet, which helps to improve the user experience; for another example, during the cleaning process of the cleaning equipment, the drive transmission mechanism can be rotated in the opposite direction to make the mounting frame rotate the cleaning body in the horizontal plane, so as to sweep the cleaning items in the area to be cleaned into the cleaning path of the cleaning equipment, which can improve the cleaning coverage and work efficiency of the cleaning equipment.

[0026] This application provides a cleaning component 100. For example... Figures 1 to 2 As shown, Figure 1 This is a schematic diagram of the structure of an embodiment of the cleaning component provided in this application; Figure 2 This is a cross-sectional structural diagram of an embodiment of the cleaning component provided in this application. The cleaning component 100 can be used in a cleaning device (not shown). Specifically, the cleaning component 100 is rotatably disposed at the bottom of the device body (not shown) of the cleaning device, and is used to sweep the objects to be cleaned from the surfaces to be cleaned, walls, corners, and other areas to be cleaned into the cleaning path of the cleaning device, so that the cleaning device can suck the objects to be cleaned into its internal dust box through the suction port, thereby improving the cleaning coverage and work efficiency of the cleaning device. The cleaning device can be a robot vacuum cleaner, a robot vacuum and mop combo, a vacuum cleaner, etc., but is not limited to these.

[0027] The cleaning component 100 includes a transmission mechanism 10, a first housing 20, and a mounting bracket 30. The transmission mechanism 10 can be the drive shaft of a direct-drive motor; it can also be the final output shaft of a non-direct-drive motor. The transmission mechanism 10 is capable of rotating in a horizontal plane. The direct-drive motor can be a servo motor, a stepper motor, or an asynchronous motor, but is not limited to these. The non-direct-drive motor can be a gear motor, a planetary geared motor, an RV reducer, or a worm geared motor, but is not limited to these.

[0028] The first housing 20 is sleeved around the transmission mechanism 10 and rotates in the horizontal plane as the transmission mechanism 10 rotates. Specifically, an insertion hole 24 can be provided in the middle of the first housing 20, and the transmission mechanism 10 is inserted into the insertion hole 24. The first housing 20 and the transmission mechanism 10 are fixedly connected, so that when the transmission mechanism 10 rotates in the horizontal plane, it will drive the first housing 20 to rotate in the horizontal plane. The first housing 20 and the transmission mechanism 10 can be fixedly connected by means of key connection, pin connection, or interference fit, but are not limited to these methods.

[0029] The mounting bracket 30 is used to mount the cleaning body 40, and serves as a support and transmission structure for the cleaning body 40. The cleaning body 40 is used to sweep the objects to be cleaned from surfaces, walls, corners, and other areas into the cleaning path of the cleaning equipment. The mounting bracket 30 and the cleaning body 40 can be detachably fixed together, allowing the cleaning body 40 to be replaced individually if it wears, deforms, or breaks during long-term use, thus saving maintenance costs. The mounting bracket 30 and the cleaning body 40 can be fixed together by detachable methods such as snap-fit ​​connections, screw connections, bolt connections, magnetic adsorption connections, or Velcro connections, but are not limited to these. Of course, the mounting bracket 30 and the cleaning body 40 can also be connected together by other non-detachable methods, such as welding.

[0030] The cleaning body 40 is mounted on one end of the mounting bracket 30, and the other end of the mounting bracket 30 is disposed inside the first housing 20, so that the mounting bracket 30 and the cleaning body 40 can rotate in the horizontal plane as the first housing 20 rotates. The middle part of the mounting bracket 30 is movably connected to the first housing 20. When the first housing 20 rotates in the horizontal plane, the mounting bracket 30 can rotate relative to the first housing 20 in both the horizontal and vertical planes. In some embodiments, the middle part of the mounting bracket 30 can be rotatably disposed in the first housing 20 via a pivot 32, and the pivot 32 extends in the horizontal direction, so that the mounting bracket 30 can rotate relative to the first housing 20 in the vertical plane.

[0031] Among them, the rotation of the mounting frame 30 in the horizontal plane means that the mounting frame 30 makes a circular motion in the horizontal plane, the direction of rotation is parallel to the horizontal direction, and the height of the mounting frame 30 in the vertical direction hardly changes; the rotation of the mounting frame 30 in the vertical plane means that the direction of rotation of the mounting frame 30 is perpendicular to the horizontal plane, and the height of the mounting frame 30 in the vertical direction changes.

[0032] When the transmission mechanism 10 drives the first housing 20 to rotate in the horizontal plane, it also drives the mounting frame 30 to rotate simultaneously in both the horizontal and vertical planes relative to the first housing 20. This allows for the lifting and lowering of one end of the mounting frame 30, which in turn lifts and lowers the cleaning body 40. Therefore, for example, when the cleaning equipment is about to be moved onto a carpet, the transmission mechanism 10 can be driven to rotate, causing the mounting frame 30 to lift the cleaning body 40, reducing or preventing the carpet from being contaminated by items to be cleaned or water stains on the cleaning body 40 when the cleaning equipment is moved onto the carpet, thus improving the user experience. Alternatively, during the cleaning process, the transmission mechanism 10 can be driven to rotate in the opposite direction, causing the mounting frame 30 to rotate the cleaning body 40 in the horizontal plane, sweeping items to be cleaned into the cleaning path of the cleaning equipment, thereby improving the cleaning coverage and efficiency of the cleaning equipment.

[0033] In some embodiments, the other end of the mounting bracket 30 is provided with a first limiting portion 31. The cleaning component 100 also includes a limiting rod 50 extending vertically. The limiting rod 50 is provided with a second limiting portion 52, which is movably connected to the first limiting portion 31, and the first limiting portion 31 can move vertically relative to the second limiting portion 52. When the first housing 20 rotates in the horizontal plane, it drives the mounting bracket 30 to rotate simultaneously in the horizontal and vertical planes relative to the limiting rod 50, thereby realizing the lifting and lowering of one end of the mounting bracket 30.

[0034] Specifically, when the first housing 20 rotates in the horizontal plane, the limiting rod 50 remains stationary, and the first housing 20 can drive the mounting frame 30 to rotate in the horizontal plane. During the rotation of the mounting frame 30 in the horizontal plane, since the middle part of the mounting frame 30 is movably connected to the first housing 20, the second limiting part 52 is movably connected to the first limiting part 31, and the limiting rod 50 remains stationary, the second limiting part 52 can push the first limiting part 31 to move in the vertical direction, so that the mounting frame 30 can rotate in the vertical plane relative to the first housing 20 through the middle part, thereby causing the height of one end of the first housing 20 in the vertical direction to change, and thus realizing the lifting and lowering of one end of the mounting frame 30.

[0035] In some embodiments, such as Figure 2 As shown, the second limiting part 52 can be a threaded tooth, and the first limiting part 31 can be a tooth that matches the threaded tooth; or, the first limiting part 31 and the second limiting part 52 can be a spline that matches each other; or, the second limiting part 52 can be a long key, and the first limiting part 31 can be a keyway that matches the long key, with the long key movably embedded in the keyway; or, the second limiting part 52 can be a spiral groove, and the first limiting part 31 can be a guide pin that matches the spiral groove, with the guide pin slidably embedded in the spiral groove.

[0036] In some embodiments, the first housing 20 is provided with a locking part 21, which is used to lock the mounting bracket 30 to prevent the mounting bracket 30 from rotating in the vertical plane. When the locking part 21 locks the mounting bracket 30, the mounting bracket 30 and the limiting rod 50 rotate in the horizontal plane.

[0037] The locking part 21 can be located in the area of ​​the first housing 20 near the lower end of the limiting rod 50 in the vertical direction. When the mounting frame 30 rotates relative to the limiting rod 50 in the vertical plane and descends to abut or connect with the locking part 21, the locking part 21 can restrict the rotation of the mounting frame 30 in the vertical plane. When the locking part 21 locks the mounting frame 30, since the second limiting part 52 of the limiting rod 50 is connected to the first limiting part 31 of the mounting frame 30, the mounting frame 30 can drive the limiting rod 50 to rotate in the horizontal plane under the cooperation of the first limiting part 31 and the second limiting part 52.

[0038] By placing the locking part 21 in the area of ​​the first housing 20 near the lower end of the limiting rod 50 in the vertical direction, when the locking part 21 locks the mounting bracket 30, the cleaning body 40 located at one end of the mounting bracket 30 can contact the surface to be cleaned, the wall edge, or the corner. At this time, the mounting bracket 30 rotates in the horizontal plane, allowing the cleaning body 40 to rotate and rub against the surface to be cleaned, the wall edge, or the corner, thereby improving the cleaning efficiency and cleaning effect of the cleaning body 40.

[0039] In some embodiments, such as Figure 2As shown, the first housing 20 has a cavity 22 and an opening 23 communicating with the cavity 22. At least a portion of the mounting bracket 30 is located within the opening 23, with one end of the mounting bracket 30 located outside the first housing 20 and the other end of the mounting bracket 30 located within the cavity 22. The inner wall of the opening 23 serves as a locking part 21, used to limit the rotation angle of the mounting bracket 30 in the vertical plane, thereby limiting the lifting range of the mounting bracket 30.

[0040] The cavity 22 can be arranged around the limiting rod 50. The shape and size of the opening 23 connecting the cavity 22 can be adapted to the shape and size of the mounting bracket 30. The two opposite sides of the opening 23 in the horizontal direction can be used to install the rotating shaft 32, that is, the two ends of the rotating shaft 32 can be fixed to the two opposite sides of the opening 23 in the horizontal direction. The middle part of the mounting bracket 30 is rotatably sleeved on the rotating shaft 32, thereby realizing the movable connection between the middle part of the mounting bracket 30 and the first housing 20. The other end of the mounting bracket 30 is located in the cavity 22, and the other end extends to the outside of the first housing 20. By making the plane of the inner wall of the opening 23 used to install the rotating shaft 32 parallel to the horizontal direction, the rotating shaft 32 is arranged to extend in the horizontal direction. When the first limiting part 31 at the other end of the mounting bracket 30 moves in the vertical direction relative to the second limiting part 52 of the limiting rod 50, the mounting bracket 30 can rotate relative to the rotating shaft 32, realizing the rotation of the mounting bracket 30 in the vertical plane.

[0041] The opening 23, which serves as the inner wall of the locking part 21, can be connected to the inner wall of the opening 23 used for mounting the rotating shaft 32, and the former can be located on one side or opposite sides of the latter in the vertical direction. The locking part 21 can restrict the mounting frame 30 from continuing to rotate after it has rotated to its position in the vertical plane. This ensures that the mounting frame 30 can only rotate within a fixed rotation angle range in the vertical plane, thereby limiting the lifting range of the mounting frame 30 and preventing excessive displacement of the mounting frame 30 in the vertical direction. On the one hand, this avoids the first limiting part 31 from disengaging from the second limiting part 52 of the limiting rod 50 due to excessive displacement of the mounting frame 30 in the vertical direction, which could lead to the entire cleaning component 100 becoming paralyzed, thus improving the reliability of the cleaning component 100. On the other hand, it ensures that when one end of the mounting frame 30 is lowered to its lowest point, the friction between the cleaning body 40 and the surface to be cleaned is moderate and does not affect the rotation of the cleaning body 40 in the horizontal plane. Furthermore, when one end of the mounting frame 30 is raised to its highest point, the cleaning body 40 will not squeeze the equipment body of the cleaning device, reducing or avoiding the risk of deformation or breakage of the cleaning body 40 due to squeezing.

[0042] In some embodiments, the lower inner wall of the opening 23 is provided as a first inclined surface 231. The height of the first inclined surface 231 gradually decreases from the side closer to the cavity 22 toward the side farther from the cavity 22. The upper inner wall of the opening 23 is provided as a second inclined surface 232, and the height of the second inclined surface 232 gradually increases from the side closer to the cavity 22 toward the side farther from the cavity 22. The inclination angle of the second inclined surface 232 relative to the horizontal plane is smaller than the inclination angle of the first inclined surface 231 relative to the horizontal plane.

[0043] Both the first inclined surface 231 and the second inclined surface 232 can serve as locking parts 21.

[0044] When the cleaning component 100 is in the cleaning state, the mounting bracket 30 abuts or connects with the first inclined surface 231. The first inclined surface 231 can lock the mounting bracket 30 so that the mounting bracket 30 can only rotate in the horizontal plane and cannot rotate in the vertical plane. Furthermore, the height of the first inclined surface 231 gradually decreases from the side closer to the cavity 22 to the side farther away from the cavity 22, so that the distance between the mounting bracket 30 and the surface to be cleaned gradually decreases from the side closer to the cavity 22 to the side farther away from the cavity 22. This allows the cleaning component 100 to maintain continuous and stable contact with the surface to be cleaned during the cleaning process, thereby improving the cleaning effect and cleaning efficiency of the cleaning component 100.

[0045] When a carpet is detected within a preset distance in front of the cleaning device along its forward direction, the transmission mechanism 10 can drive the first housing 20 to rotate in the opposite direction to the rotation direction of the cleaning state. This causes the first housing 20 to drive the mounting frame 30 to rotate in the opposite direction to the rotation direction of the cleaning state. The end of the mounting frame 30 on which the cleaning body 40 is mounted can rotate in the vertical plane and be lifted upward under the action of the second limiting part 52 and the first limiting part 31. During the lifting process, when the end of the mounting frame 30 on which the cleaning body 40 is mounted abuts or connects with the second inclined surface 232, the second inclined surface 232 can lock the mounting frame 30 so that the mounting frame 30 cannot rotate in the vertical plane. At this time, the transmission mechanism 10 can be controlled to stop rotating, so that when the cleaning device moves to the carpet, the cleaning body 40 will not only not come into contact with the carpet, but will also remain stationary. This can reduce or avoid the cleaning objects, water stains, etc. on the cleaning body 40 falling onto the carpet due to the rotation of the cleaning body 40 in the horizontal plane.

[0046] By gradually increasing the height of the second inclined plane 232 from the side closer to the cavity 22 to the side farther away from the cavity 22, the distance between the mounting bracket 30 and the carpet gradually increases from the side closer to the cavity 22 to the side farther away from the cavity 22. Furthermore, the inclination angle of the second inclined plane 232 relative to the horizontal plane is smaller than the inclination angle of the first inclined plane 231 relative to the horizontal plane. This ensures that the mounting bracket 30 is raised to a moderate height, preventing the cleaning body 40 from contacting the carpet or the cleaning equipment body. This reduces or avoids the risk of contamination of the carpet and / or the equipment body by cleaning materials, water stains, etc. on the cleaning body 40.

[0047] In some embodiments, such as Figure 2 As shown, the limiting rod 50 includes a screw 51 that extends vertically. The second limiting part 52 is the threaded tooth of the screw 51, and the first limiting part 31 is a tooth that matches the threaded tooth.

[0048] The screw 51 has continuous threaded teeth on its outer surface as a second limiting part 52, and the other end of the mounting bracket 30 has teeth that match the threaded teeth as a first limiting part 31. The teeth of the mounting bracket 30 are movably embedded in the grooves of the threaded teeth of the screw 51. When the mounting bracket 30 rotates in the horizontal plane, the teeth of the mounting bracket 30 can mesh with the threaded teeth of the screw 51 to drive the teeth to move along the trajectory of the threaded teeth. This converts the rotation of the mounting bracket 30 in the horizontal plane into the movement of the teeth of the mounting bracket 30 in the vertical direction. As a result, the middle part of the mounting bracket 30 can rotate in the vertical plane relative to the first housing 20 through the rotating shaft 32, so that the other end of the mounting bracket 30 drives the cleaning body 40 to rotate simultaneously in the horizontal and vertical planes.

[0049] In some embodiments, such as Figure 2 As shown, the cleaning component 100 also includes a damping component 60. The damping component 60 is sleeved on the end of the limiting rod 50 away from the second limiting part 52, and is configured to prevent the limiting rod 50 from rotating in the horizontal plane relative to the first housing 20 when the mounting bracket 30 moves in the vertical direction relative to the limiting rod 50.

[0050] Specifically, when the mounting bracket 30 rotates in the horizontal plane and is not in contact with or connected to the locking part 21, the damping force provided by the damping member 60 to the limiting rod 50 can prevent the limiting rod 50 from rotating in the horizontal plane with the first housing 20, so that the first limiting part 31 of the mounting bracket 30 can move continuously and stably relative to the second limiting part 52 in the vertical direction, thereby enabling the middle part of the mounting bracket 30 to rotate continuously and stably relative to the first housing 20 in the vertical plane, which can improve the lifting efficiency and stability of the cleaning body 40.

[0051] In some embodiments, when the locking part 21 locks the mounting bracket 30, since the locking part 21 can lock the mounting bracket 30 to rotate in the vertical plane, the displacement component of the first limiting part 31 in the vertical direction can be converted into the displacement component of the second limiting part 52 in the horizontal direction, so that the limiting rod 50 can overcome the damping force of the damping member 60 and follow the mounting bracket 30 to rotate in the horizontal plane.

[0052] In some embodiments, the damping element 60 may be made of silicone, polyurethane (PU), thermoplastic elastomer (TPE), or nitrile rubber (NBR), but is not limited thereto.

[0053] In some embodiments, the transmission mechanism 10 is configured with a forward rotation mode and a reverse rotation mode. In the forward rotation mode, the first housing 20 rotates clockwise in the horizontal plane, the first limiting part 31 moves downward in the vertical direction relative to the second limiting part 52, and one end of the mounting bracket 30 moves upward relative to the limiting rod 50 until the mounting bracket 30 is limited by the second inclined surface 232. In the reverse rotation mode, the first housing 20 rotates counterclockwise in the horizontal plane, the first limiting part 31 moves upward in the vertical direction relative to the second limiting part 52, and one end of the mounting bracket 30 moves downward relative to the limiting rod 50 until the mounting bracket 30 is limited by the first inclined surface 231.

[0054] The direction of rotation of the transmission mechanism 10 in the horizontal plane is viewed from above in the vertical direction. That is, when the transmission mechanism 10 is in the forward rotation mode, it rotates clockwise in the horizontal plane when viewed from above in the vertical direction; when the transmission mechanism 10 is in the reverse rotation mode, it rotates counterclockwise in the horizontal plane when viewed from above in the vertical direction.

[0055] Specifically, in forward rotation mode, the transmission mechanism 10 rotates clockwise in the horizontal plane, driving the first housing 20 to rotate clockwise in the horizontal plane, so that the first housing 20 drives the mounting frame 30 to rotate clockwise in the horizontal plane. Since the first limiting part 31 of the mounting frame 30 is movably connected to the second limiting part 52 on the limiting rod 50, and the middle part of the mounting frame 30 is movably connected to the first housing 20, when the mounting frame 30 rotates clockwise in the horizontal plane, the first limiting part 31 moves downward in the vertical direction relative to the second limiting part 52, so that the end of the mounting frame 30 on which the cleaning body 40 is mounted moves upward relative to the limiting rod 50, realizing the lifting of the cleaning body 40 until the mounting frame 30 is limited by the second inclined surface 232, and the mounting frame 30 and the cleaning body 40 stop moving upward. The working principle of the transmission mechanism 10 in the reverse mode is the same as that in the forward mode, but the technical effect is opposite, that is, it can achieve the descent of the cleaning body 40. The specific implementation of the transmission mechanism 10 in the reverse mode can be referred to its relevant description in the forward mode.

[0056] In some embodiments, the transmission mechanism 10 can also drive the cleaning body 40 to descend in forward rotation mode and drive the cleaning body 40 to rise in reverse rotation mode. Specifically, in forward rotation mode, the first housing 20 rotates clockwise in the horizontal plane, the first limiting part 31 moves upward in the vertical direction relative to the second limiting part 52, and one end of the mounting bracket 30 moves downward relative to the limiting rod 50 until the mounting bracket 30 is limited by the first inclined surface 231. In reverse rotation mode, the first housing 20 rotates counterclockwise in the horizontal plane, the first limiting part 31 moves downward in the vertical direction relative to the second limiting part 52, and one end of the mounting bracket 30 moves upward relative to the limiting rod 50 until the mounting bracket 30 is limited by the second inclined surface 232.

[0057] The following embodiments are described using the example of the first housing 20 rotating clockwise in the horizontal plane in forward rotation mode to lift the cleaning body 40, and the first housing 20 rotating counterclockwise in the horizontal plane in reverse rotation mode to lower the cleaning body 40.

[0058] In some embodiments, the cleaning device further includes a processor (not shown), a detection component (not shown), and a drive mechanism 200. The detection component is used to detect the road conditions of the cleaning device. For example, the detection component can detect whether there is carpet within a preset distance in front of the cleaning device along the forward direction; if carpet is detected within the preset distance in front of the cleaning device along the forward direction, it indicates that the cleaning device is about to move into the carpeted area. The preset distance can be the distance between the front end of the cleaning device in the forward direction and the edge of the carpet. When the detection component detects that the cleaning device is about to move into the carpeted area, it sends a lifting signal. In response to the lifting signal sent by the detection component, the processor controls the drive mechanism 200 to drive the transmission mechanism 10 into a forward rotation mode, thereby lifting the cleaning body 40.

[0059] In some embodiments, such as Figures 1 to 2 As shown, the cleaning component 100 also includes a second housing 70 and a hovering recognition mechanism 80. The end of the transmission mechanism 10 away from the first housing 20 is movably connected to the second housing 70. The hovering recognition mechanism 80 is disposed on the second housing 70 and is used to recognize the rotation angle of the transmission mechanism 10, and to generate a hovering signal when the rotation angle is a preset angle. The hovering signal is used to control the transmission mechanism 10 to stop transmission.

[0060] The end of the transmission mechanism 10 furthest from the first housing 20 can pass through the second housing 70 and extend to the side of the second housing 70 facing away from the first housing 20. The transmission mechanism 10 can rotate relative to the second housing 70 in the horizontal plane; that is, when the transmission mechanism 10 rotates in the horizontal plane, the second housing 70 cannot rotate with the transmission mechanism 10 in the horizontal plane. When the cleaning component 100 is in cleaning mode, the hovering recognition mechanism 80 is not always active. Instead, the hovering recognition mechanism 80 is activated only when the cleaning component 100 completes its cleaning task or when the cleaning equipment is about to move to the carpet area. This prevents the hovering recognition mechanism 80 from generating a hovering signal every time the transmission mechanism 10 rotates to a preset angle.

[0061] In some embodiments, when the cleaning unit 100 completes its cleaning task or the cleaning equipment is about to move to the carpet area, the cleaning body 40 needs to be raised to avoid secondary contamination of the surface to be cleaned or contamination of the carpet. The detection component sends a raising signal when it detects that the cleaning equipment is about to move to the carpet area or that the entire area to be cleaned has been cleaned. The processor can respond to the raising signal by controlling the hovering recognition mechanism 80 to start. The hovering recognition mechanism 80 can identify the rotation angle of the transmission mechanism 10 during the raising of the cleaning body 40. The hovering recognition mechanism 80 can generate a hovering signal when it first identifies the rotation angle of the transmission mechanism 10 as a preset angle, or it can generate a hovering signal when it identifies the rotation angle of the transmission mechanism 10 as a preset angle for the second, third, or fifth time. The specific number of recognitions can be selected based on the number of rotations of the transmission mechanism 10 when the cleaning body 40 rotates from the lowest preset height to the highest preset height. The lowest preset height can be the height of the cleaning body 40 when the mounting bracket 30 is locked by the first inclined surface 231; the highest preset height can be the height of the cleaning body 40 when the mounting bracket 30 is locked by the second inclined surface 232. When the hover recognition mechanism 80 generates a hover signal, the processor can control the drive mechanism 200 to shut down, thereby controlling the transmission mechanism 10 to stop transmission.

[0062] By setting up a hovering recognition mechanism 80, the cleaning body 40 can stop at a fixed preset angle. When the cleaning body 40 stops at the fixed preset angle, it can be mostly or completely located under the main body of the cleaning device. That is, the orthographic projection of the main body towards the cleaning body 40 completely covers or covers most of the cleaning body 40, and the cleaning body 40 is in a free state without being squeezed. This not only allows the cleaning body 40 to be folded under the main body, making the entire cleaning device look cleaner and more stylish, thus enhancing its appearance, but also prevents the cleaning body 40 from deforming or breaking due to long-term pressure, helping to extend its service life.

[0063] In some embodiments, the hover recognition mechanism 80 includes an optocoupler 81 and a rotating block 82. The optocoupler 81 is disposed on the second housing 70. The rotating block 82 is connected to the transmission mechanism 10 and rotates in the horizontal plane as the transmission mechanism 10 rotates. When the light-shielding part 83 of the rotating block 82 rotates into the optical path of the optocoupler 81, the optocoupler 81 generates a hover signal.

[0064] Since the second housing 70 cannot rotate in the horizontal plane with the transmission mechanism 10, the optocoupler 81 is mounted on the second housing 70, allowing the optocoupler 81 to remain stationary relative to the transmission mechanism 10. When the cleaning unit 100 is in cleaning mode, the optocoupler 81 is not always on. It is activated only when the cleaning unit 100 completes its cleaning task or when the cleaning equipment is about to move to the carpet area. This prevents the optocoupler 81 from generating a hovering signal every time the light-shielding part 83 of the rotating block 82 enters its optical path.

[0065] The rotating block 82 is positioned circumferentially in the transmission mechanism 10, corresponding to the mounting bracket 30 in the same direction. This means the angle between the light-shielding portion 83 of the rotating block 82 and the mounting bracket 30 is fixed. This ensures that when the light-shielding portion 83 of the rotating block 82 rotates into the optical path of the optocoupler 81, the angle between the light-shielding portion 83 and the mounting bracket 30 remains constant, allowing the block to stop at a fixed preset angle. The angle between the light-shielding portion 83 and the mounting bracket 30 can be 0° to 360°, for example, 0°, 20°, 30°, 50°, 60°, 90°, 100°, 120°, 150°, 160°, 180°, 200°, 230°, 260°, 270°, 290°, 300°, 320°, 350°, 360°, etc., but is not limited to these.

[0066] In some embodiments, such as Figure 1 As shown, the cleaning component 100 also includes a cleaning body 40, which is mounted on one end of the mounting bracket 30. That is, the cleaning body 40 is mounted on the end of the mounting bracket 30 away from the first limiting portion 31. The cleaning body 40 can be a brush.

[0067] This application also provides a cleaning device. The cleaning device includes a device body and a cleaning component 100 as described in any of the above embodiments. The device body is provided with a drive mechanism 200. The cleaning component 100 is disposed on the device body, and its transmission mechanism 10 is drively connected to the drive mechanism 200.

[0068] The drive mechanism 200 includes a drive component 201 and a transmission assembly 202, which are sequentially connected in a transmission manner. The drive component 201 provides power to the transmission assembly 202. The transmission assembly 202 processes the power and direction of the drive component 201 (if the transmission assembly 202 is a planetary reduction gear, the planetary reduction gear can adjust the speed and increase the torque of the drive component 201) and transmits it to the transmission mechanism 10, so that the transmission mechanism 10 can drive the first housing 20 to rotate. The transmission assembly 202 can be a conventional transmission gear, a planetary reduction gear, a connecting rod assembly, or a worm gear assembly, but is not limited to these.

[0069] In this embodiment, the specific structure of the cleaning component 100 is the same as that in the above embodiments. Since the cleaning device adopts all the technical solutions of all the embodiments of the cleaning component 100, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0070] This application provides a cleaning component 100 and a cleaning device. The cleaning component 100 includes: a transmission mechanism 10; a first housing 20, sleeved outside the transmission mechanism 10 and rotating in a horizontal plane as the transmission mechanism 10 rotates; and a mounting frame 30, one end of which is used to mount a cleaning body 40, and the other end of which is disposed inside the first housing 20, with a first limiting part 31 at the end of the other end. The middle part of the mounting frame 30 is movably connected to the first housing 20. When the first housing 20 rotates in the horizontal plane, the mounting frame 30 can rotate simultaneously in both the horizontal and vertical planes relative to the first housing 20. When the transmission mechanism 10 drives the first housing 20 to rotate in the horizontal plane, it drives the mounting frame 30 to rotate simultaneously in both the horizontal and vertical planes relative to the first housing 20, enabling the lifting and lowering of one end of the mounting frame 30. When one end of the mounting frame 30 lifts and lowers, it can drive the lifting and lowering of the cleaning body 40. Therefore, for example, when the cleaning equipment is about to be moved onto the carpet, the drive transmission mechanism 10 can be rotated to lift the cleaning body 40 by the mounting frame 30, reducing or preventing the carpet from being contaminated by the cleaning items, water stains, etc. on the cleaning body 40 when the cleaning equipment is moved onto the carpet, which helps to improve the user experience; for another example, during the cleaning process of the cleaning equipment, the drive transmission mechanism 10 can be rotated in the opposite direction to rotate the cleaning body 40 in the horizontal plane by the drive transmission mechanism 10, so as to sweep the cleaning items in the area to be cleaned into the cleaning path of the cleaning equipment, which can improve the cleaning coverage and work efficiency of the cleaning equipment.

Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
