[0100] Specific embodiments

[0101] The technical solution of the embodiment of the present invention is clearly and fully described below, in conjunction with the accompanying figures of the embodiment of the present invention. It is clear that the described embodiment represents only a portion of the embodiments of the present invention, and not all of them. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in the field without any creative work fall within the scope of protection of the present invention.

[0102] Furthermore, the present invention may repeat reference numbers and / or letters in various ways; this repetition is for the sake of simplicity and clarity and is not in itself an indication of a relationship between the various embodiments and / or settings discussed. In addition, various specific methods and materials are provided in the present invention, but ordinary technicians in the field may implement other methods and / or use other materials.

[0103] The cleaning device generally uses the rotation of the cleaning elements to perform the cleaning work; however, if several cleaning elements are placed, it is necessary to place several drive mechanisms to actuate the different cleaning elements respectively, which makes the size of the whole machine too bulky.

[0104] The present invention is described below in conjunction with the accompanying figures and with reference to the specific embodiment:

[0105] An embodiment of the present invention provides a cleaning device, see [Fig.1], comprising a housing 100, a plurality of cleaning elements 400, and a drive mechanism, the plurality of cleaning elements 400 are mounted on the housing 100; the drive mechanism is directly or connected so as to be able to be driven by each of the cleaning elements 400, and the drive mechanism is used to drive the plurality of cleaning elements 400 so that they move relative to the housing 100.

[0106] The placement of several cleaning elements 400 can increase the effective cleaning area of ​​the cleaning elements 400 and improve the cleaning effect of the cleaning elements 400; by driving a larger number of cleaning elements 400 to rotate relative to the housing 100 through a smaller number of drive elements 200, it is possible to reduce the number of drive elements 200 and thus the space occupied by the drive elements 200, making the arrangement of the cleaning device more compact to minimize the volume of the cleaning device; by using a smaller number of drive elements 200 to drive a larger number of cleaning elements 400, it is possible to reduce the total weight of the drive elements 200 to facilitate the movement of the cleaning device.By reducing the number of training elements 200, the space occupied by the training elements 200 is thus reduced; the cost of the training elements 200 can be reduced by reducing the number of training elements 200.

[0107] When the drive mechanism is used to drive several cleaning elements 400 to move relative to the housing 100, the movement may include rotation, reciprocating movement, vibration, etc. An embodiment of the present invention is illustrated by a drive mechanism allowing several cleaning elements 400 to rotate relative to the housing 100.

[0108] The drive element 200 can be placed on the housing 100, and the cleaning element 400 moves relative to the housing 100 under the action of the drive element 200.

[0109] Referring to Figures 1 to 2, the cleaning device provided by the embodiment of the present invention comprises a support 300; the cleaning element 400 is mounted on the support 300; the support 300 can move between a first position and a second position; in the case where the support 300 is in the first position, the cleaning element 400 is connected to the drive shaft of the drive element 200; in the case where the support 300 moves to the second position, the cleaning element 400 separates from the drive shaft of the drive element 200, and in the case where the support 300 is in the second position, the cleaning element 400 can separate from the support 300.

[0110] By switching the support 300 between the first position and the second position, the cleaning element 400 changes from the operating state to the disassembled state; when the support 300 is in the first position, the cleaning element 400 is connected to the drive shaft of the drive element 200, so that the cleaning element 400 rotates relative to the housing 100 under the action of the drive element 200 to perform the cleaning work; when the support 300 is in the second position, the cleaning element 400 can separate from the support 300, so as to facilitate the disassembly of the cleaning element 400 for replacement or cleaning.In the event that the support 300 moves to the second position, the cleaning element 400 separates from the drive shaft of the drive element 200, it is possible to prevent the operator from being accidentally injured by the work of the cleaning element 400 during dismantling of the cleaning element 400, and to improve safety.

[0111] The embodiment of the present invention achieves the rapid switching of the cleaning element 400 between the working state and the disassembled state by the movement of the support 300; The cleaning element 400 is mounted on the support 300, and the cleaning element 400 can be moved beyond the mounting position by the simple action of rotating the support 300, so that the disassembly operation of the cleaning element 400 does not need to be confined to a narrow mounting position; in which, the mounting position of the cleaning element 400 is the position in which the cleaning element 400 is located when the cleaning element 400 rotates relative to the housing 100 under the action of the drive element 200.

[0112] When the support 300 moves to the second position, the cleaning element 400 separates from the drive shaft of the drive element 200. In other words, when the cleaning element 400 enters the disassembled state, the cleaning element 400 and the drive shaft of the drive element 200 decouple, thus preventing the cleaning element 400 from rotating relative to the housing 100 under the drive mechanism, thereby reducing the risk of accidental injury to an operator during the disassembly of the cleaning element 400. Thanks to the movement of the support 300, rapid connection and separation between the cleaning element 400 and the drive element 200 can also be achieved when switching between the working and disassembled states of the cleaning element 400. to improve the security of the operation.

[0113] In the case where the support 300 is in the second position, the cleaning element 400 can separate from the support 300, which allows the cleaning element 400 to be removed for cleaning or replacement; similarly, in the case where the support 300 is in the second position, the cleaned or replaced cleaning element 400 can be mounted on the support 300, and the support 300 can be moved to complete the mounting of the cleaning element 400.

[0114] The drive element 200 is placed on the housing 100, and the cleaning element 400 rotates relative to the housing 100 under the action of the drive element 200. The drive element 200 is fixed by the housing 100 in order to reduce the oscillation of the cleaning element 400 during the working process.

[0115] The 400 cleaning element can be a cleaning brush, a mop, etc.

[0116] In certain embodiments, refer to Figures 1 to 2, a retention groove 110 of the cleaning element 400 is placed on the housing, and the support 300 rotates in the direction (the direction e as in [Fig. 1]) from the inside of the retention groove 110 to the outside of the retention groove 110. The rotation of the support 300 causes the cleaning element 400 to move from the inside of the retention groove 110 to the outside of the retention groove 110, which reduces the spatial restriction during disassembly to avoid hitting the inner wall of the retention groove 110 or other parts inside the retention groove 110 when disassembling the cleaning element 400, thus reducing the difficulty of disassembling the cleaning element 400.In the case where the cleaning element 400 is in the working state, the cleaning element 400 is partially located inside the retention groove 110; in other words, the retention groove 110 is the mounting position of the cleaning element 400. The retention groove 110 provides physical protection to the cleaning element 400, while the retention groove 110 provides. the mechanical support and strength required for the cleaning element 400 to rotate in the correct position.

[0117] In some embodiments, a movable shaft 120 is placed on one of the supports 300 and the housing 100, and a coupling groove 321 on the other; the movable shaft 120 moves within the coupling groove 321 such that the support 300 moves from the first to the second position. For example, referring to Figures 3 to 4, a movable shaft 120 is placed on the housing 100 and a coupling groove 321 is placed on the support 300.

[0118] The relative movement of the support 300 and the housing 100 is achieved by the movement of the movable shaft 120 inside the coupling groove 321, so as to effect the switching of the support 300 between the first position and the second position; During the rotation of the support 300, the movable shaft 120 is confined inside the coupling groove 321, in other words, the support 300 and the housing 100 always maintain a coupling relationship; the support 300 rotates to move the cleaning element 400 beyond the mounting position, so as to facilitate the dismantling of the cleaning element 400; the support 300 moves to the first position to move the cleaning element 400 mounted on the support 300 to the mounting position, which allows the disassembled cleaning element 400 to be mounted quickly and precisely to the mounting position, thus accelerating the mounting of the cleaning element 400.

[0119] Of course, in other embodiments, it is also possible that a movable shaft 120 is placed on the support 300 and that a coupling groove 321 is placed on the housing 100, and the embodiment of the present invention is not particularly limited in this respect.

[0120] In certain embodiments, refer to [Fig. 5], the coupling groove 321 extends in the direction of the rotating shaft of the cleaning element 400 (the direction f as in [Fig. 5]), so that the cleaning element can rotate around the movable shaft 120 when the movable shaft 120 moves inside the coupling groove 321. When the cleaning element is placed obliquely upwards, the cleaning elements on the left and right sides do not interfere with each other, so that the cleaning element 400 located on the support 300 can be close to or far from the drive element 200, thus allowing the cleaning element 400 to be connected to or separated from the drive shaft of the drive element 200.

[0121] In some embodiments, refer to [Fig.5], the end of the coupling groove 321 has a curved inner wall to fit the curved outer surface of the movable shaft 120 in order to facilitate the rotation of the support 300 with the movable shaft 120 as the center of rotation.

[0122] In certain embodiments, refer to Figures 5 to 6, the coupling groove 321 is inclined at the far end of the cleaning element 400 in the direction away from the housing 100 (the direction g as in [Fig.6]), so that the coupling groove 321 at the far end of the cleaning element 400 can correspond to the rotation path of the support 300, which allows a smoother rotation process of the support 300.

[0123] In certain embodiments, refer to Figures 5 to 6, the support 300 comprises a base 310 and a connecting lug 320, the connecting lug 320 is placed protruding on the base 310, and the coupling groove 321 is placed on the connecting lug 320, so that the position of the coupling groove 321 can be quickly locked during assembly to accelerate the assembly speed; Furthermore, compared to the direct placement of the coupling groove 321 on the base 310, in the embodiment of the present invention, the connecting lug 320 is placed protruding on the base 310, thus allowing the rotating support 300 to avoid the housing 100 or other components mounted on the housing 100, which makes the rotation of the support 300 relatively flexible.

[0124] In certain embodiments, refer to Figures 6 to 7, a mounting groove 130 for the connecting lug 320 is formed on the housing 100 to confine the connecting lug 320 inside the mounting groove 130, thereby reducing the oscillation of the connecting lug 320 during the rotation of the support 300 and improving the stability of the rotation of the support 300; The movable shaft 120 is threaded onto a side wall of the mounting groove 130, and when the connecting lug 320 moves inside the mounting groove 130, the movable shaft 120 moves inside the coupling groove 321, thus obtaining a coupling between the movable shaft 120 and the coupling groove 321.For example, the mounting groove 130 has a first side wall 131 and a second side wall 132 positioned opposite each other, the connecting lug 320 is located between the first side wall 131 and the second side wall 132, and the rotating shaft passes through the first side wall 131, the coupling groove 321, and the second side wall 132 in sequence. When the connecting lug 320 moves between the first side wall 131 and the second side wall 132, the movable shaft 120 moves relative to the coupling groove 321, thus switching between the first and second positions of the support 300. Two connecting lugs 320 can be positioned to ensure the stability of the rotation of the support 300. The embodiment of the present invention does not specifically limit the number of connecting lugs 320.

Positioning groove 140 limits the movement of positioning part 360 so that support 300 remains in the first position for normal operation of the cleaning element 400. Positioning part 360 may be partially located inside positioning groove 140, or may be entirely located inside positioning groove 140, provided that positioning groove 140 can limit the movement of positioning part 360; the shape of positioning groove 140 may be adapted to positioning part 360 to provide a better fixing effect on positioning part 360.

[0126] The positioning part 360 is connected to the base 310, and the positioning groove 140 can be connected to the fixing groove 130 to facilitate machining. Two positioning parts 360 can be placed, and the two positioning parts 360 can improve the fixing effect of the support 300.

[0127] In some embodiments, refer to [Fig.8], a first guide surface 141 is placed on the positioning groove 140, the support 300 slides out of the positioning groove 140 through the first guide surface 141.The relative sliding between the first guide surface 141 and the positioning part 360 can reduce the difficulty for the support 300 to slide out of the positioning groove 140, which allows the support 300 to move from the first to the second position; the first guide surface 141 can be a curved surface or an inclined surface, and the embodiment of the present invention does not specifically limit the specific shape of the first guide surface 141; the first guide surface 141 is placed on the side of the positioning groove 140 away from one side of the center of rotation of the support 300, in other words, the first guide surface 141 is placed on the side of the positioning groove 140 away from the coupling groove 321.

[0128] In certain embodiments, refer to [Fig. 8], a second guide surface 330 is placed on the positioning portion 360, and the support 300 slides out of the positioning groove 140 through the second guide surface 330. The relative sliding between the second guide surface 330 and the positioning groove 140 can reduce the difficulty for the support 300 to slide out of the positioning portion 360, thus allowing the support 300 to move from the first to the second position. The second guide surface 330 can be a curved or inclined surface, and the embodiment of the present invention does not specifically limit the specific shape of the second guide surface 330. The second guide surface 330 is placed on the side of the positioning portion. 360 away from one side of the center of rotation of the support 300, in other words, the second guide surface 330 is placed on the side of the positioning part 360 away from the moving shaft 120.

[0129] In some embodiments, refer to [Fig.8], the positioning groove 140 has a first guide surface 141 and a second guide surface 330 is placed on the positioning part 360. The relative sliding between the first guide surface 141 and the second guide surface 330 can reduce the difficulty for the support 300 to slide out of the positioning groove 140, which allows the support 300 to move from the first position to the second position.

[0130] In certain embodiments, refer to [Fig. 9], the cleaning device further comprises a cover body 500, the cover body 500 covering at least part of the positioning groove 140. The fact that the cover body 500 covers the positioning groove 140 confines the positioning part 360 within the positioning groove 140, which allows the support 300 to remain in its initial position, thus ensuring the normal operation of the cleaning element 400. The cover body 500 may cover all or part of the positioning groove 140, provided that the cover body 500 can prevent the positioning part 360 from sliding out of the positioning groove 140. Before disassembling the cleaning element 400, it is possible to separate the cover body 500 from the positioning groove 140.By sliding the positioning part 360 out of the positioning groove 140, this rotates the support 300 to disassemble the cleaning element 400 from the support 300.

[0131] In some embodiments, refer to [Fig.9], an extension part 170 is placed in the notch of the retention groove 110, the cover body 500 fits into the retention groove 110, and the cover body 500 is connected to the extension part 170 to complete the connection between the cover body 500 and the housing 100; A working window 510 is generally placed on the cover body 500, and a part of the cleaning element 400 extends out of the working window 510 to perform the cleaning work; To facilitate processing, the extension part 170 is an extension plate.

A rotating head 630 can be placed on the support element 600, and the shape of the head The rotating head 630 can be adapted to the slot 721 to improve the firmness of the connection between the drive element 200 and the support 600; Several projections can be placed on the peripheral side of the rotating head 630, and several depressions can be placed on the inner wall of the slot 721, and when the rotating head 630 is inserted into the slot 721, the projections are located in the depressions, preventing the relative rotation of the rotating head 630 and the drive element 200; in the assembled state, the spacing adjustment can be made between the rotating head 630 and the slot 721 to facilitate disassembly, as long as the slot 721 can actuate the rotating head 630 to rotate. The 630 rotating head and the 600 support element can be screwed together or formed as a single piece.The support element 600 serves as a support for the cleaning element 400 and, at the same time, the connection between the cleaning element 400 and the drive element 200 can be made by the support element 600, so that the cleaning element 400 rotates relative to the housing 100 under the drive of the drive element 200.

[0133] It must be understood that in the case where the cleaning element 400 is in the first position, the rotating head 630 is located in the slot groove 721 so that the cleaning element 400 is connected to the drive mechanism and rotates relative to the housing 100 under the action of the drive mechanism to perform the cleaning work; And in the case where the cleaning element 400 moves from the first position to the second position, the rotating head 630 is removed from the slot groove 721 so that, in the case where the cleaning element 400 is in the second position, the cleaning element 400 can separate from the drive mechanism, so as to facilitate the disassembly of the cleaning element 400 for replacement or cleaning.

[0134] In some embodiments, refer to [Fig.12], the dimension of the support element 600 in the longitudinal direction of the cleaning element 400 (the direction h as in [Fig. 12]) is greater than or equal to half the length of the cleaning element 400, which can provide a greater support span for the cleaning element 400 and reduce the bending and deformation of the cleaning element 400, thereby increasing the stability and load-bearing capacity of the cleaning device.

[0135] In certain embodiments, where "a first coupling surface 412 and a second coupling surface 413 are formed on opposite sides of the coupling projection 410," the first coupling surface 412 is located at the end of the coupling projection 410 furthest from the drive element 200, and a stop element 610 is placed at the end of the support element 600 furthest from the drive element 200. A first stop surface 611 which fits into the first coupling surface 412 is formed on the stop element 610; the first coupling surface 412 fits into the first stop surface 611 to limit the slippage of the support element 600 inside the coupling hole 411, preventing the cleaning element 400 from separating from the support element 600 during rotation; the first coupling surface 412 can be a curved surface or an inclined surface, and the embodiment of the present invention does not specifically limit the specific shape of the first coupling surface 412.

[0136] Referring to [Fig. 13], in certain embodiments, a disassembly guide surface 613 is placed on the first stop surface 611, and the disassembly guide surface 613 is used to slide in conjunction with the first mating surface 412 when the cleaning element 400 is disassembled. The relative sliding between the mounting guide surface 612 and the mating hole 411 allows the first mating surface 412 to fit onto the first stop surface 611, thus enabling the support element 600 to be properly mounted in the mating hole 411. The mounting guide surface 612 may be a curved or inclined surface, and the embodiment of the present invention does not specifically limit the specific shape of the mounting guide surface 612.

[0137] Referring to Figures 12 to 14, in certain embodiments, in the case where "a first coupling surface 412 and a second coupling surface 413 are formed on opposite sides of the coupling projection 410", the second coupling surface 413 is located at the end of the coupling projection 410 near the drive element 200. A second stop surface 611 which fits the second coupling surface 413 is formed on the support element 600.The second mating surface 413 fits against the second stop surface to limit the slippage of the support element 600 within the mating hole 411. During assembly, the support element 600 extends into the mounting hole until the second mating surface 413 fits against the second stop surface. The second mating surface 413 then quickly engages with the second stop surface to rapidly lock the mounting position of the support element 600 within the mounting hole, thus improving assembly efficiency. The distance between the first mating surface 412 and the second mating surface 413 is equal to the distance between the first stop surface 611 and the second stop surface, which enhances the robustness of the connection between the support element 600 and the cleaning element 400.

[0138] Refer to Figures 12 to 14; in certain embodiments, a mounting guide surface 612 is formed on the stop element 610. The minimum angle between the mounting guide surface 612 and axial direction of cleaning element 400 is acute.

[0139] Referring to Figures 12 to 14, in certain embodiments, a rebound space 620 of the stop 610 is formed on the support element 600. Under the effect of the force, the relative sliding between the dismantling guide surface 613 and the first coupling surface 412 is achieved, and the stop element 610 retracts into the rebound space 620, allowing the support element 600 to be properly withdrawn from the coupling hole 411.

[0140] Referring to Figures 12 to 14, in some embodiments, the minimum distance between the inner wall of the rebound space 620 and the drive element 200 is less than that between the first coupling surface 412 and the drive element 200, so that the end of the stop element 610 away from the drive element 200 is suspended and the stop element 610 is elastic, which facilitates the return of the stop element 610 into the rebound space 620 after being under the effect of the force.

[0141] Referring to Figures 12 to 15, in some embodiments, a limit part 640 is placed on the support element 600, the limit part 640 is located between several stop elements 610, and a gap is formed between the limit part 640 and the stop elements 610. The stop element 610 retracts in the rebound space 620 until the stop element 610 fits into the limit part 640, whereby the limit part 640 can limit the degree of retraction of the stop element 610, avoiding excessive bending of the stop element 610 which leads to a fracture.

[0142] In certain embodiments, the stop element 610 is at least partially elastic, facilitating the return of the stop element 610 located in the rebound space 620 to its original position. The stop element 610 may be fully elastic or partially elastic, and the embodiment of the present invention is not particularly limited in this respect.

[0143] In certain embodiments, refer to Figures 13 to 14, at least two stop elements 610 are placed, and each of the stop elements 610 is distributed in the peripheral side direction of the support element 600, facilitating the coupling between the stop elements 610 and the coupling holes 411.

[0144] In certain embodiments, refer to Figures 13 to 14, two stop elements 610 are positioned, and a rebound gap 620 is formed between the opposite sides of the stop elements 610. During the mounting or dismounting of the cleaning element 400, the stop element 610 is bent towards the opposite side under the effect of force, and the rebound gap 620 is located between the two stop elements 610 on opposite sides, so that the stop elements 610 can retract into the gap. rebound 620, allowing the cleaning element 400 to be properly mounted or dismounted; At the same time, the rebound space 620 is placed between the stop elements 610 on opposite sides to maximize the volume of the rebound space 620, making the movement of the stop element 610 more flexible.

[0145] In some embodiments, refer to Figures 13 to 14, a sliding groove 650 is placed on the stop element 610, and the sliding groove 650 can be slidably coupled with the coupling projection 410, which makes the coupling between the cleaning element 400 and the support element 600 smoother thanks to the sliding coupling between the sliding groove 650 and the coupling projection 410.

[0146] In certain embodiments, refer to Figures 13 to 14, the internal walls of the sliding groove 650 and the coupling projection 410 in the axial direction of the cleaning element 400 are curved, which can reduce the sliding resistance between the sliding groove 650 and the coupling projection 410, thus improving the disassembly and assembly efficiency.

[0147] In certain embodiments, refer to [Fig.14], a connecting part 340 is placed on the support 300, the connecting part 340 rests on the outside of said support element outside of the support element 600.The support element 600 allows the cleaning element 400 to be mounted on the support 300; the connecting part 340 rests on the outside of the support element 600 to act as a support for the support element 600, so that the support element 600 remains stable in the working state; The support element 600 can rotate relative to the connecting part 340, so as to prevent the support 300 from rotating with the rotation of the support element 600; In order to achieve the relative rotation between the support element 600 and the support 300, a bearing 350 can be mounted between the support element 600 and the support 300, so that the support element 600 can rotate smoothly relative to the support 300.To achieve relative rotation between the support element 600 and the support 300, a bearing 350 can be installed between the support element 600 and the support 300, allowing the support element 600 to rotate freely relative to the support 300. The connecting part 340 can be connected to the base 310.

[0148] Referring to [Fig. 15], the cleaning element 400 has a free end 420 and a fixed end 430. The fixed end 430 can be removably connected to the drive element 200. When disassembling the cleaning element 400, it is sufficient to detach the fixed end 430 from the cleaning element 400, thus reducing the disassembly workload while ensuring the normal operation of the cleaning element 400. The drive element 200 is placed on the housing 100, and the drive element 200 is fixed by the housing 100 to ensure the stability of the drive element 200 during operation; The fixed end 430 of the cleaning element 400 can be removably connected to the drive element 200, and the drive element 200 plays a supporting and driving role for the cleaning element 400.

[0149] The fixed end 430 of the cleaning element 400 can be removably connected to the drive element 200; When the cleaning element 400 is in the working state, the drive element 200 can actuate the cleaning element 400 to rotate relative to the housing 100 through the fixed end 430; When the cleaning element 400 is in the disassembled state, it is possible to directly remove the fixed end 430 from the drive element 200, thus reducing the disassembly operation; As the free end 420 of the cleaning element 400 is suspended, the position of the free end 420 of the cleaning element 400 has a larger operating space, so as to avoid the housing 100 or other parts during disassembly.

[0150] In the present invention, a single drive element 200 operates several cleaning elements 400, thus avoiding the need to configure a separate drive element 200 for each cleaning element 400, thereby reducing the equipment purchase cost. Maintaining a single drive element 200 generally requires fewer spare parts and less repair time than maintaining multiple drive elements 200, making the installation of a single drive element 200 more economical. Uniform use also allows a single drive element 200 to operate multiple cleaning elements 400, facilitating troubleshooting of the cleaning device and enabling the timely identification and resolution of problems.Furthermore, using a single 200 drive element to drive multiple 400 cleaning elements can reduce energy losses, improve overall energy efficiency, optimize energy use, and reduce energy consumption.

[0151] During the operation of the cleaning device, several cleaning elements 400 are generally required to move synchronously. Therefore, using fewer drive elements 200 can ensure synchronized operation of all the cleaning elements 400 to improve the operating efficiency of the cleaning device. Using a single drive element 200 is also more conducive to centralized control and monitoring of multiple cleaning elements 400, thereby increasing the degree of automation and the responsiveness of the cleaning device.

[0152] Referring to [Fig. 15], the embodiment of the present invention further comprises at least one transmission element 700, the transmission element 700 being connected to the corresponding cleaning element 400; The transmission element 700, driven by the drive element 200, actuates the corresponding cleaning element 400 to move.

[0153] The transmission element 700 can transmit the power generated by the drive element 200 to each cleaning element 400, so that each cleaning element 400 rotates relative to the housing 100, thus achieving that a smaller number of drive elements operate a larger number of cleaning elements 400 to work; The transmission element 700 can consist of several gears or pulleys of different diameters to achieve the adjustment of the rotational speed, so as to obtain the speed regulation effect; Different transmission elements 700 can have different transmission ratios, achieving that several cleaning elements 400 rotate at different speeds.

[0154] Referring to [Fig. 16], the embodiment of the present invention further comprises a connecting element 800, the connecting element 800 being connected to at least two transmission elements 700 to achieve synchronized movement of several transmission elements 700; The output shaft of the drive element 200 is connected to the connecting element 800, and several transmission elements 700 can be driven synchronously by driving the connecting element 800. Thanks to the connection between the connecting element 800 and several transmission elements 700, it is sufficient for the drive element 200 to be connected to the connecting element 800 to actuate several transmission elements 700 to rotate.The drive element 200 does not need to be directly connected to multiple transmission elements 700 for a more flexible mounting position of the drive element 200, which facilitates the overall layout of the cleaning device and makes the structure of the cleaning device more compact. The connecting element can be a rod, and multiple transmission elements 700 can be distributed in the longitudinal direction (direction i as in [Fig. 16]) of the connecting element 800, and the rod-shaped connecting element 800 can save space.

[0155] In other embodiments, the output shaft of the drive element 200 can be connected to at least one transmission element 700, and the drive element 200 can drive one of the transmission elements 700, and then actuate another transmission element 700 to move through the linkage 800, to achieve the effect that one drive mechanism actuates several transmission elements 700 to move, thus achieving that a single drive element actuates several cleaning elements 400 to rotate relative to the housing 100. The output shaft of the drive element 200 can be connected to one transmission element 700 or to two, three or four transmission elements 700 to ensure the stability of the rotation of the cleaning element 400, which is not limited by the embodiment of the present invention.

[0156] In other embodiments, the output shaft of the drive element 200 can be connected to the linking element 800 and to at least one transmission element 700 in order to improve the stability of the power transmission and to ensure stable rotation of the cleaning element 400. In general, the drive element 200 is a motor.

[0157] In some embodiments, refer to [Fig.17], the transmission element 700 comprises an input wheel 710 and an output wheel 720, the output wheel 720 is connected to the output shaft of the drive mechanism, and the input wheel 710 and the output wheel 720 are coupled so that the drive element 200 drives the output wheel 720 to rotate through the coupling of the output wheel 720 and the input wheel 710.

[0158] In certain embodiments, refer to Figures 17 to 18, the transmission element 700 comprises a first transmission element 730, the first transmission element 730 comprises a first input wheel 731 and two first output wheels 732, the first input wheel 731 is connected to the drive shaft of the drive element 200, one of the first output wheels 732 is connected to the corresponding cleaning element 400, and the other first output wheel 732 is connected to the linking element 800; The first output wheel 732 is connected by the drive shaft of the drive element 200 to achieve the connection between the first transmission element 730 and the drive element 200, then the rotation of the linking element 800 and the cleaning element 400 corresponding to the first transmission element 730 is driven by the first transmission element 730.The first input wheel 731 is coupled to one of the first output wheels 732, and one of the first output wheels 732 is coupled to the other first output wheel 732. The first input wheel 731 can drive the corresponding cleaning element 400 to rotate, and at the same time, the first input wheel 731 can drive the other cleaning elements 400 to rotate via the linking element 800 to achieve the rotation of several cleaning elements 400 relative to the housing 100. In other embodiments, the first input wheel 731 can also be coupled to the first two output wheels 732 to drive the first two output wheels 732 to rotate.

[0159] Referring to Figures 18 to 19, the transmission element 700 may also include a second transmission element 740, the second transmission element 740 includes a second input wheel 741 and a second output wheel 742, the second input wheel 741 is connected to the linking element 800, the second output wheel 742 is connected to the corresponding cleaning element 400, and the second input wheel 741 is coupled to the second output wheel 742 to allow the rotation of the corresponding cleaning element 400.

[0160] Referring to [Fig.20], the socket groove 721 can be placed on the output wheel 720 so that the output wheel 720 rotates the corresponding cleaning element 400.

[0161] In some embodiments, the output wheels 720 connected to the different cleaning elements 400 have the same rotational speed, which allows the cleaning elements 400 to rotate in a synchronized manner to allow coupling between the cleaning elements 400, thus achieving the transfer of debris between the cleaning elements 400.

[0162] In certain embodiments, refer to [Fig. 21], two transmission elements 700 are placed, the transmission elements 700 being located on opposite sides of the housing 100; One end of the linking element 800 is connected to one of the transmission elements 700 and the other end is connected to the other transmission element 700. The transmission elements 700 are located on opposite sides of the housing 100, which reduces energy loss when the linking element 800 transmits power, and at the same time allows the linking element 800 to ensure that the transmission elements 700 on both sides of the housing 100 achieve synchronized movement.By connecting the linking element 800 to the transmission elements 700 located on opposite sides of the housing 100, the force and torque can be distributed more evenly throughout the cleaning device, which helps to reduce stress concentration and extend the service life of the transmission elements 700 and the linking element 800. The transmission elements 700 are located on opposite sides of the housing 100, which reduces the risk of vibration and imbalance that can be caused by the transmission element 700 being located on only one side, and makes the operation of the entire cleaning device more stable and reliable.

[0163] In certain embodiments, refer to [Fig.21], the output shaft of the drive element 200 is placed in the direction of the rotating shaft of the cleaning element 400. Since the drive element 200 is generally elongated and its length direction is the extension direction of the output shaft of the drive element 200, the output shaft of the drive element 200 is placed along the direction of the rotating shaft of the cleaning element 400 to reduce the size of the drive element 200 in the vertical direction (the j direction as in [Fig.21]) and thus the size of the cleaning device in the vertical direction, which allows for the miniaturization and flattening of the cleaning device.The rotating shaft of the cleaning element 400, in other words, the rotating shaft of the cleaning element 400 in the working state; the vertical direction is the direction of the height of the cleaning device in the operating state.

[0164] In certain embodiments, refer to [Fig. 21], several drive elements 700 are respectively positioned at the ends of the housing 100, which allows for more efficient use of space inside the cleaning device, makes the cleaning device more compact, and enables miniaturization of the cleaning device. Positioning the drive element 700 at the end of the housing 100 facilitates the assembly, maintenance, and repair of the drive element 700 and allows maintenance personnel to inspect the drive element 700 more quickly.

[0165] In certain embodiments, refer to [Fig. 22], a mounting groove 160 for the drive element 700 is formed at the end of the housing. The mounting groove 160 allows for the positioning and alignment of the drive element 700 to ensure that the transmission element 700 is correctly mounted on the housing 100 and to prevent the transmission element 700 from being loose or dislodged.

[0166] In certain embodiments, the extension direction from the fixed end 430 to the free end 420 of the cleaning element 400 points towards the other cleaning element 400, so that a gap is formed between the free ends 420 of the two adjacent cleaning elements 400. This allows for the disassembly and assembly of the cleaning element 400 and simultaneously facilitates the passage of dust through both cleaning elements 400. The extension direction from the fixed end 430 to the free end 420 of the cleaning element 400 pointing towards the other cleaning element 400 can increase the size of the cleaning device in the axial direction of the cleaning element 400, thereby increasing cleaning efficiency, and at the same time reduce the length of the individual cleaning element 400, thereby reducing the oscillation of the cleaning element 400 during operation.

[0167] In some embodiments, refer to [Fig. 22], a dust collection orifice 150 is formed on the housing 100, and the dust swept by the cleaning element 400 can be collected by the dust collection orifice 150; in the axial direction of the cleaning element 400, the area between two cleaning elements 400 and the dust collection orifice 150 overlaps at least partially, which can reduce the obstruction of the dust collection orifice 150 by the cleaning element 400, so that the swept-off dust can properly enter the dust collection orifice 150. The area between the two cleaning elements 400 and the dust collection orifice 150 can overlap completely or partially.The dust removal port 150 can be connected to a dust removal component, which can collect impurities such as dust, and the dust removal component can be a dust bag or a dust collection box; A dust extraction component, such as a fan, . can be placed on the dust removal component, and the dust suction component can provide the power needed to remove impurities such as dust.

[0168] In some embodiments, a guide plate is placed on the housing 100 (not shown in the Figure), the guide plate allows to direct the impurities towards the dust removal orifice 150, the guide plate acts as a guide to direct the impurities towards the dust removal orifice 150.

[0169] The embodiment of the present invention provides a cleaning system comprising a base station and said cleaning device.

[0170] It is understood that the cleaning device has a beneficial effect of the above embodiment, and then the cleaning system has a corresponding beneficial effect of the above embodiment, the specific embodiment of which may refer to the above embodiment, and the present application does not repeat it.

[0171] The cleaning device generally uses the rotation of cleaning elements to perform the cleaning task; however, during the operation of the cleaning elements, hair and other impurities tend to become entangled in them, making them difficult to clean or replace. For example, cleaning devices such as sweeping robots generally use a cleaning brush to clean the floor, and after a certain period of cleaning, hair or dirt tends to become entangled in the cleaning brush, which must then be removed for cleaning or replacement. However, to ensure the proper functioning of the cleaning brush, the cleaning brush and the relevant technology are closely linked to the drive system of the sweeping robot, making its disassembly difficult.

[0172] The embodiment of the present invention also provides a cleaning device, refer to Figures 24 to 26, comprising a housing 100, a drive element 200, a support 300, and a cleaning element 400; The drive element 200 is placed on the housing 100, and the cleaning element 400 rotates relative to the housing 100 under the action of the drive element 200, and the cleaning element 400 is mounted on the support 300; The support 300 can rotate between the first and second positions; When the support 300 is in the first position, the cleaning element 400 is connected to the drive shaft of the drive element 200; When the support 300 rotates to the second position, the cleaning element 400 separates from the drive shaft of the drive element 200, and when the support 300 is in the second position, the cleaning element 400 can separate from the support 300.

[0173] The support 300 can rotate relative to the housing 100. By switching the support 300 between the first position and the second position, the cleaning element 400 changes from the operating state to the disassembled state; when the support 300 is in the first position, the cleaning element 400 is connected to the drive shaft of the drive element 200, so that the cleaning element 400 rotates relative to the housing 100 under the action of the drive element 200 to perform the cleaning work; when the support 300 is in the second position, the cleaning element 400 can separate from the support 300, so as to facilitate the disassembly of the cleaning element 400 for replacement or cleaning.In the event that the support 300 rotates to the second position, the cleaning element 400 separates from the drive shaft of the drive element 200 to prevent the cleaning element 400 from rotating and accidentally injuring an operator during the removal of the cleaning element 400, thus improving safety. Figure 24 is a three-dimensional structural diagram of the cleaning device when the support 300 is in the second position, and Figure 26 is a three-dimensional structural diagram of the cleaning device when the support 300 is in the first position.

[0174] The embodiment of the present invention achieves the rapid switching of the cleaning element 400 between the working state and the disassembled state by the rotation of the support 300; The cleaning element 400 is mounted on the support 300, and the cleaning element 400 can be moved beyond the mounting position by the simple action of rotating the support 300, so that the disassembly operation of the cleaning element 400 does not need to be confined to a narrow mounting position; in which, the mounting position of the cleaning element 400 is the position in which the cleaning element 400 is located when the cleaning element 400 rotates relative to the housing 100 under the action of the drive element 200.

[0175] In the event that the support 300 rotates to the second position, the cleaning element 400 separates from the drive shaft of the drive element 200. In other words, when the cleaning element 400 enters the disassembled state, the cleaning element 400 and the drive shaft of the drive element 200 decouple, so as to prevent the situation in which the cleaning element 400 in the disassembled state rotates relative to the housing 100, reducing the risk of accidentally injuring an operator by the rotation of the cleaning element 400 in the event of its disassembly. Thanks to the rotation of the support 300, when switching between the working state and the disassembled state of the cleaning element 400, a quick connection and separation between the cleaning element 400 and the drive element 200 can also be achieved in order to improve the safety of the operation.

[0176] In the case where the support 300 is in the second position, the cleaning element 400 can separate from the support 300, which allows the cleaning element 400 to be removed for cleaning or replacement; Similarly, in the case where the support 300 is in the second position, the cleaned or replaced cleaning element 400 can be mounted on the support 300, and the support 300 can be rotated to complete the mounting of the cleaning element 400.

[0177] The drive element 200 is placed on the housing 100, and the cleaning element 400 rotates relative to the housing 100 under the action of the drive element 200. The drive element 200 is fixed by the housing 100 in order to reduce the oscillation of the cleaning element 400 during the working process.

[0178] The 400 cleaning element can be a cleaning brush, a mop, etc.

[0179] In certain embodiments, refer to Figures 24 to 26, a groove of The retention bracket 110 for the cleaning element 400 is placed on the housing, and the support 300 rotates in the direction (direction e as shown in [Fig. 24]) from the inside of the retention groove 110 to the outside of the retention groove 110. The rotation of the support 300 causes the cleaning element 400 to move from the inside of the retention groove 110 to the outside of the retention groove 110, which reduces the spatial restriction during disassembly to avoid hitting the inner wall of the retention groove 110 or other parts inside the retention groove 110 when removing the cleaning element 400, thus reducing the difficulty of removing the cleaning element 400. When the cleaning element 400 is in its working state, the cleaning element 400 is partially located inside the retention groove 110. In other words, the retention groove 110 is the mounting position of the cleaning element 400.The retention groove 110 provides physical protection to the cleaning element 400, while the retention groove 110 provides the mechanical support and strength necessary for the cleaning element 400 to rotate into the correct position.

[0180] In some embodiments, a movable shaft 120 is placed on one of the supports 300 and the housing 100, and a coupling groove 321 is placed on the other support 300 and the housing 100. The movable shaft 120 moves within the coupling groove 321 such that the support 300 moves from the first to the second position. For example, referring to Figures 3 to 4, a movable shaft 120 is placed on the housing 100, and a coupling groove 321 is placed on the support 300.

[0181] The relative displacement of the support 300 and the housing 100 is achieved by the movement of the movable shaft 120 within the coupling groove 321, so as to switch the support 300 between the first position and the second position; During the rotation of the support 300, the movable shaft 120 is confined to inside the coupling groove 321, in other words, the support 300 and the housing 100 always maintain a coupling relationship; the support 300 rotates to the second position to move the cleaning element 400 beyond the mounting position, so as to facilitate the dismantling of the cleaning element 400; the support 300 rotates to the first position to move the cleaning element 400 mounted on the support 300 to the mounting position, which allows the dismantled cleaning element 400 to be mounted quickly and precisely to the mounting position, thus accelerating the mounting of the cleaning element 400.

[0182] Of course, in other embodiments, it is also possible that a movable shaft 120 is placed on the support 300 and that a coupling groove 321 is placed on the housing 100, and the embodiment of the present invention is not particularly limited in this respect.

[0183] In certain embodiments, refer to [Fig.5], the coupling groove 321 extends in the direction of the rotating shaft of the cleaning element 400 (the direction f as in [Fig.5]), so that the cleaning element 400 located on the support 300 can be close to or far from the drive element 200 during the movement of the movable shaft 120 inside the coupling groove 321, thus allowing the cleaning element 400 to be connected to or separated from the drive shaft of the drive element 200. If the coupling groove 321 is located on the support 300 and the coupling groove 321 extends in the direction of the rotating shaft of the cleaning element 400, this means that the coupling groove 321 extends in the direction of the rotating shaft of the cleaning element 400 in the case where the support 300 is in the first position.

[0184] In some embodiments, refer to [Fig.5], the end of the coupling groove 321 has a curved inner wall to fit the curved outer surface of the movable shaft 120 in order to facilitate the rotation of the support 300 with the movable shaft 120 as the center of rotation.

[0185] In some embodiments, refer to Figures 5 to 6, the coupling groove 321 is inclined at the far end of the cleaning element 400 in the direction away from the housing 100 (the direction g as in [Fig.6]), so that the coupling groove 321 at the far end of the cleaning element 400 can correspond to the rotation path of the support 300, which allows a smoother rotation process of the support 300.

[0186] In certain embodiments, refer to Figures 5 to 6, the support 300 comprises a base 310 and a connecting lug 320, the connecting lug 320 is projecting onto the base 310, and the coupling groove 321 is positioned on the connecting lug 320, so that the position of the coupling groove 321 can be quickly locked during assembly to accelerate the speed of assembly; In addition, compared to the direct placement of the coupling groove 321 on the base 310, in the embodiment of the present invention, the connecting lug 320 is placed protruding on the base 310, thus allowing the rotating support 300 to avoid the housing 100 or other components mounted on the housing 100, which makes the rotation of the support 300 relatively flexible.

[0187] In certain embodiments, refer to Figures 6 to 7, a mounting groove 130 for the connecting lug 320 is formed on the housing 100 to confine the connecting lug 320 inside the mounting groove 130, thereby reducing the oscillation of the connecting lug 320 during the rotation of the support 300 and improving the stability of the rotation of the support 300; The movable shaft 120 is threaded onto a side wall of the mounting groove 130, and when the connecting lug 320 moves inside the mounting groove 130, the movable shaft 120 moves inside the coupling groove 321, thus obtaining a coupling between the movable shaft 120 and the coupling groove 321.For example, the mounting groove 130 has a first side wall 131 and a second side wall 132 positioned opposite each other, the connecting lug 320 is located between the first side wall 131 and the second side wall 132, and the rotating shaft passes through the first side wall 131, the coupling groove 321, and the second side wall 132 in sequence. When the connecting lug 320 moves between the first side wall 131 and the second side wall 132, the movable shaft 120 moves relative to the coupling groove 321, thus switching between the first and second positions of the support 300. Two connecting lugs 320 can be positioned to ensure the stability of the rotation of the support 300. The embodiment of the present invention does not specifically limit the number of connecting lugs 320.

[0188] In certain embodiments, refer to [Fig. 25], a positioning groove 140 is placed on the housing 100 and a positioning part 360 is placed on the support 300; when the support 300 is in the first position, the positioning part 360 is at least partially located inside the positioning groove 140. The positioning groove 140 limits the movement of the positioning part 360 so that the support 300 remains in the first position for normal operation of the cleaning element 400.The positioning part 360 may be partially located inside the positioning groove 140, or may be entirely located inside the positioning groove 140, provided that the positioning groove 140 is capable of limiting the movement of the positioning part 360; the shape of the positioning groove 140 may adapt to the positioning part 360 in order to provide a better fixing effect on the positioning part 360.

[0189] The positioning part 360 is connected to the base 310, and the positioning groove 140 can be connected to the fixing groove 130 to facilitate machining. Two positioning parts 360 can be placed, and the two positioning parts 360 can improve the fixing effect of the support 300.

[0190] In some embodiments, refer to [Fig.25], a first guide surface 141 is placed on the positioning groove 140, the support 300 slides out of the positioning groove 140 through the first guide surface 141.The relative sliding between the first guide surface 141 and the positioning part 360 can reduce the difficulty for the support 300 to slide out of the positioning groove 140, which allows the support 300 to move from the first to the second position; the first guide surface 141 can be a curved surface or an inclined surface, and the embodiment of the present invention does not specifically limit the specific shape of the first guide surface 141; the first guide surface 141 is placed on the side of the positioning groove 140 away from one side of the center of rotation of the support 300, in other words, the first guide surface 141 is placed on the side of the positioning groove 140 away from the coupling groove 321.

[0191] In some embodiments, refer to [Fig.25], a second guide surface 330 is placed on the positioning part 360, the support 300 slides out of the positioning groove 140 through the second guide surface 330.The relative sliding between the second guide surface 330 and the positioning groove 140 can reduce the difficulty for the support 300 to slide out of the positioning part 360, which allows the support 300 to move from the first to the second position; the second guide surface 330 can be a curved surface or an inclined surface, and the embodiment of the present invention does not specifically limit the specific shape of the second guide surface 330; the second guide surface 330 is placed on the side of the positioning part 360 away from one side of the center of rotation of the support 300, in other words, the second guide surface 330 is placed on the side of the positioning part 360 away from the movable shaft 120.

[0192] In some embodiments, refer to [Fig.25], the positioning groove 140 has a first guide surface 141 and a second guide surface 330 is placed on the positioning part 360. The relative sliding between the first guide surface 141 and the second guide surface 330 can reduce the difficulty for the support 300 to slide out of the positioning groove 140, which allows the support 300 to move from the first position to the second position.

[0193] In certain embodiments, refer to [Fig. 9], the cleaning device further comprises a cover body 500, the cover body 500 covers at least part of the positioning groove 140. The fact that the cover body 500 covers the positioning groove 140 confines the positioning part 360 within the positioning groove 140, which allows the support 300 to remain in its initial position, thus ensuring the normal operation of the cleaning element 400. The cover body 500 can cover all or part of the positioning groove 140, provided that the cover body 500 prevents the positioning part 360 from sliding out of the positioning groove 140. Before removing the cleaning element 400, it is possible to separate the cover body 500 from the positioning groove 140. By sliding the positioning part 360 out of the positioning groove 140, the support 300 rotates to remove the cleaning element 400 from the support 300.

[0194] In some embodiments, refer to [Fig.9], an extension part 170 is placed in the notch of the retention groove 110, the cover body 500 fits into the retention groove 110, and the cover body 500 is connected to the extension part 170 to complete the connection between the cover body 500 and the housing 100; A working window 510 is generally placed on the cover body 500, and a part of the cleaning element 400 extends out of the working window 510 to perform the cleaning work; To facilitate processing, the extension part 170 is an extension plate.

[0195] In certain embodiments, refer to Figures 10 to 11, the cleaning device further comprises a support element 600, a socket groove 721 is placed on the drive element 200, and a coupling hole 411 is placed inside the cleaning element 400; One end of the support element 600 is threaded through the coupling hole 411, and the other end is removably coupled inside the socket groove 721.A rotating head 630 can be placed on the support element 600, and the shape of the rotating head 630 can fit the slot 721 to improve the strength of the connection between the drive element 200 and the support 600; Several projections can be placed on the peripheral side of the rotating head 630, and several depressions can be placed on the inner wall of the slot 721, and when the rotating head 630 is inserted into the slot 721, the projections are located in the depressions, preventing the relative rotation of the rotating head 630 and the drive element 200. The rotating head 630 and the support element 600 can be screwed together or formed as a single piece. The support element 600 serves as a support for the cleaning element 400 and, at the same time, the connection between the cleaning element 400 and the drive element 200. can be achieved by the support element 600, so that the cleaning element 400 rotates relative to the housing 100 under the drive of the drive element 200.

[0196] In some embodiments, refer to [Fig. 12], the dimension of the support element 600 in the longitudinal direction of the cleaning element 400 (the direction h as in [Fig. 12]) is greater than or equal to half the length of the cleaning element 400, which can provide a greater support span for the cleaning element 400 and reduce bending and deformation of the cleaning element 400, thereby increasing the stability and load-bearing capacity of the cleaning device.

[0197] In certain embodiments, refer to Figures 12 to 13, a first mating surface 412 is placed inside the mating hole 411, and a stop element 610 is placed on the support element 600. A first stop surface 611 that fits the first mating surface 412 is formed on the stop element 610; the first mating surface 412 fits the first stop surface 611 to limit the slippage of the support element 600 inside the mating hole 411, preventing the cleaning element 400 from separating from the support element 600 during rotation; the first mating surface 412 may be a curved surface or an inclined surface, and the embodiment of the present invention does not specifically limit the specific shape of the first mating surface 412.

[0198] In certain embodiments, refer to Figures 12 to 13, a mounting guide surface 612 is formed on the stop element 610. The mounting guide surface 612 allows the first mating surface 412 to fit onto the first stop surface 611. The relative sliding between the mounting guide surface 612 and the mating hole 411 allows the first mating surface 412 to fit onto the first stop surface 611, thus allowing the support element 600 to be properly mounted in the mating hole 411. The mounting guide surface 612 may be a curved or inclined surface, and the embodiment of the present invention does not specifically limit the specific shape of the mounting guide surface 612. The mounting guide surface 612 may be located at the end of the stop element. 610.

The second mating surface 413 fits onto the second stop surface to limit the sliding of the support element 600 inside the mating hole 411; During assembly, the support element 600 extends into the mounting hole until the second mating surface 413 fits into the second stop surface, and the second coupling surface 413 quickly fits into the second stop surface to quickly lock the mounting position of the support element 600 inside the mounting hole, thus improving mounting efficiency.

[0200] In certain embodiments, refer to Figures 12 to 13, a first coupling surface 412 can be placed inside the coupling hole 411, and a first stop surface 611 which fits the first coupling surface 412 is formed on the stop element 610, while a second coupling surface 413 is placed inside the coupling hole 411, and a second stop surface which fits the second coupling surface 413 is formed on the support element 600; The support element 600 is limited to a particular position inside the coupling hole 411 by the first coupling surface 412 and the second coupling surface 413.A coupling projection 410 is placed on the cleaning element 400, the coupling projection 410 is placed inside the coupling hole 411, and a first coupling surface 412 and a second coupling surface 413 are formed on opposite sides of the coupling projection 410 to secure the support element 600. The distance between the first coupling surface 412 and the second coupling surface 413 is equal to the distance between the first stop surface 611 and the second stop surface, which improves the robustness of the connection between the support element 600 and the cleaning element 400.

[0201] In certain embodiments, refer to Figures 12 to 13, a disassembly guide surface 613 is placed on the first stop surface 611. During disassembly of the cleaning element 400, the first coupling surface 412 separates from the first stop surface 611 by the relative sliding between the disassembly guide surface 613 and the first coupling surface 412, thus allowing the support element 600 to be properly removed from the coupling hole 411. The disassembly guide surface 613 may be a curved or inclined surface, and the embodiment of the present invention does not specifically limit the specific shape of the disassembly guide surface 613.

[0202] In certain embodiments, refer to Figures 12 to 13, a rebound space 620 of the stop 610 is formed on the support element 600. Under the effect of the force, the relative sliding between the dismantling guide surface 613 and the first coupling surface 412 is achieved, and the stop element 610 retracts into the rebound space 620, allowing the support element 600 to be properly withdrawn from the coupling hole 411.

[0203] In certain embodiments, refer to Figures 12 to 13, at least two stop elements 610 are placed, and each of the stop elements 610 is distributed in the peripheral side direction of the support element 600, facilitating the coupling between the stop elements 610 and the coupling holes 411. A rebound space 620 can be formed between the stop elements 610 to maximize the volume of the rebound space 620, which allows for more flexible movement of the stop elements 610.

[0204] In certain embodiments, the stop element 610 is at least partially elastic, facilitating the return of the stop element 610 located in the rebound space 620 to its original position. The stop element 610 may be fully elastic or partially elastic, and the embodiment of the present invention is not particularly limited in this respect.

The connecting part 340 can be connected to the base 310.

[0206] Referring to [Fig. 27], the cleaning element 400 has a free end 420 and a fixed end 430. The fixed end 430 can be removably connected to the drive element 200. When disassembling the cleaning element 400, it is sufficient to detach the fixed end 430 from the cleaning element 400, which reduces the disassembly workload while ensuring the normal operation of the cleaning element 400. The drive element 200 is placed on the housing 100, and the drive element 200 is fixed by the housing 100 to ensure the stability of the drive element 200 during operation. The fixed end 430 of the cleaning element 400 can be removably connected to the drive element 200, and the drive element 200 plays a supporting and driving role for the cleaning element 400.

[0207] The fixed end 430 of the cleaning element 400 can be removably connected to the drive element 200; When the cleaning element 400 is in the working state, the drive element 200 can actuate the cleaning element 400 to rotate relative to the housing 100 through the fixed end 430; When the cleaning element 400 is in the disassembled state, it is possible to directly remove the fixed end 430 from the drive element 200, thus reducing the disassembly operation; As the free end 420 of the cleaning element 400 is suspended, the position of the free end 420 of the cleaning element 400 has a larger operating space, so as to avoid the housing 100 or other parts during disassembly.

[0208] In certain embodiments, refer to [Fig. 27], at least two cleaning elements 400 are positioned, and the arrangement of several cleaning elements 400 can increase the effective cleaning area and improve the cleaning effect of the cleaning device; The cleaning element 400 has a fixed end 430 and a free end 420, and the fixed end 430 of the cleaning element 400 is connected to the housing 100 by the bracket 300. When disassembling the cleaning element 400, it is sufficient to detach the fixed end 430 from the cleaning element 400, thus reducing the disassembly workload; The free end 420 of the cleaning element 400 extends towards the other cleaning element 400, which can reduce the impact on the other cleaning element 400 when dismantling one of the cleaning elements 400, allowing the independence of each cleaning element 400 to be maintained.

[0209] The drive element 200 is connected by transmission to each of the cleaning elements 400, and the drive element 200 is used to drive several cleaning elements 400 to rotate relative to the housing 100. By driving several cleaning elements 400 to rotate relative to the housing 100 through a drive element 200, it is possible to reduce the number of drive elements 200 and thus their occupied space, making the layout of the cleaning device more compact to minimize the volume of the cleaning device; By using a drive element 200 to drive several cleaning elements 400, it is possible to reduce the total weight of the drive elements 200 to facilitate the movement of the cleaning device.

[0210] In the present invention, a single drive element 200 operates several cleaning elements 400, thus avoiding the need to configure a separate drive element 200 for each cleaning element 400, thereby reducing the equipment purchase cost. Maintaining a single drive element 200 generally requires fewer spare parts and less repair time than maintaining multiple drive elements 200, making it more economical. The assembly of a single 200 drive element. Uniform use also allows a single 200 drive element to operate multiple 400 cleaning elements, facilitating troubleshooting of the cleaning device and enabling timely detection and resolution of problems. Furthermore, using a single 200 drive element to power multiple 400 cleaning elements can reduce energy losses, improve overall energy efficiency, optimize energy utilization, and lower energy consumption.

[0211] During the operation of the cleaning device, several cleaning elements 400 are generally required to move synchronously. Therefore, using a single drive element 200 can ensure synchronized operation of all the cleaning elements 400 to improve the operating efficiency of the cleaning device. Using a single drive element 200 is also more conducive to centralized control and monitoring of several cleaning elements 400, thereby increasing the degree of automation and the responsiveness of the cleaning device.

[0212] Referring to [Fig.27], the embodiment of the present invention further comprises several transmission elements 700, the transmission element 700 is connected to the corresponding cleaning element 400; The transmission element 700, driven by the drive element 200, actuates the corresponding cleaning element 400 to rotate.

[0213] The transmission element 700 can transmit the power generated by the drive element 200 to each cleaning element 400, so that each cleaning element 400 rotates relative to the housing 100, thus achieving that a drive mechanism actuates several cleaning elements 400 to work; The transmission element 700 can consist of several gears or pulleys of different diameters to achieve the adjustment of the rotational speed, so as to obtain the speed regulation effect; Different transmission elements 700 can have different reduction ratios, achieving that several cleaning elements 400 rotate at different speeds.

[0214] Referring to [Fig. 16], the embodiment of the present invention further comprises a connecting element 800. The connecting element 800 is connected to at least two transmission elements 700 to achieve synchronized movement of several transmission elements 700. The output shaft of the drive element 200 is connected to the connecting element 800, and several transmission elements 700 can be driven synchronously by driving the connecting element 800. Thanks to the connection between the connecting element 800 and several transmission elements 700, it is sufficient for the drive element 200 to be connected to the connecting element 800 to actuate several transmission elements 700 to rotate. The drive element The connecting element 200 does not need to be directly connected to multiple transmission elements 700, allowing for a more flexible mounting position of the drive element 200. This facilitates the overall layout of the cleaning device and makes its structure more compact. The connecting element can be a rod, and multiple transmission elements 700 can be distributed along the longitudinal direction (direction i as shown in [Fig. 16]) of the connecting element 800. The rod-shaped connecting element 800 can save space.

[0215] In other embodiments, the output shaft of the drive element 200 can be connected to at least one transmission element 700, and the drive element 200 can drive one of the transmission elements 700, and then actuate another transmission element 700 to move through the linkage 800, to achieve the effect that one drive mechanism actuates several transmission elements 700 to move, thus achieving that a single drive mechanism actuates several cleaning elements 400 to rotate relative to the housing 100. The output shaft of the drive element 200 can be connected to one transmission element 700 or to two, three or four transmission elements 700 to ensure the stability of the rotation of the cleaning element 400, which is not limited by the embodiment of the present invention.

[0216] In other embodiments, the output shaft of the drive element 200 can be connected to the linking element 800 and to at least one transmission element 700 in order to improve the stability of the power transmission and to ensure stable rotation of the cleaning element 400. In general, the drive element 200 is a motor.

[0217] In some embodiments, refer to [Fig.17], the transmission element 700 comprises an input wheel 710 and an output wheel 720, the output wheel 720 is connected to the output shaft of the drive element 200, and the input wheel 710 and the output wheel 720 are coupled so that the drive element 200 drives the output wheel 720 to rotate through the coupling of the output wheel 720 and the input wheel 710.

[0218] In certain embodiments, refer to Figures 17 to 18, the transmission element 700 comprises a first transmission element 730, the first transmission element 730 comprises a first input wheel 731 and two first output wheels 732, the first input wheel 731 is connected to the drive shaft of the drive element 200, one of the first output wheels 732 is connected to the corresponding cleaning element 400, and the other first output wheel 732 is connected to the linking element 800; the first output wheel 732 is connected via the drive shaft of the drive element 200 to establish the connection between the first transmission element 730 and the drive element 200, then the The first input wheel 731 is coupled to one of the first output wheels 732, and one of the first output wheels 732 is coupled to the other first output wheel 732. The first input wheel 731 can drive the corresponding cleaning element 400 to rotate, and simultaneously, the first input wheel 731 can drive the other cleaning elements 400 to rotate via the linking element 800, thus achieving the rotation of several cleaning elements 400 relative to the housing 100. In other embodiments, the first input wheel 731 can also be coupled to the first two output wheels 732 to drive the first two output wheels 732 to rotate.

[0219] Referring to Figures 18 to 19, the transmission element 700 may also include a second transmission element 740, the second transmission element 740 includes a second input wheel 741 and a second output wheel 742, the second input wheel 741 is connected to the linking element 800, the second output wheel 742 is connected to the corresponding cleaning element 400, and the second input wheel 741 is coupled to the second output wheel 742 to allow the rotation of the corresponding cleaning element 400.

[0220] Referring to [Fig.20], the interlocking groove 721 can be placed on the output wheel 720 so that the output wheel 720 rotates the corresponding cleaning element 400.

[0221] In certain embodiments, refer to [Fig. 28], two transmission elements 700 are placed, the transmission elements 700 being located on opposite sides of the housing 100; One end of the linking element 800 is connected to one of the transmission elements 700 and the other end is connected to the other transmission element 700. The transmission elements 700 are located on opposite sides of the housing 100, which reduces the energy loss when the linking element 800 transmits power, and at the same time allows the linking element 800 to ensure that the transmission elements 700 on both sides of the housing 100 achieve synchronized movement.By connecting the linking element 800 to the transmission elements 700 located on opposite sides of the housing 100, the force and torque can be distributed more evenly throughout the cleaning device, which helps to reduce stress concentration and extend the service life of the transmission elements 700 and the linking element 800. The transmission elements 700 are located on opposite sides of the housing 100, which reduces the risk of vibration and imbalance that can be caused by the transmission element 700 being located on only one side, and makes the operation of the entire cleaning device more stable and reliable.

[0222] In certain embodiments, refer to [Fig.28], the output shaft of the drive element 200 is placed in the direction of the rotating shaft of the cleaning element 400. Since the drive element 200 is generally elongated and its length direction is the extension direction of the output shaft of the drive element 200, the output shaft of the drive element 200 is placed along the direction of the rotating shaft of the cleaning element 400 to reduce the size of the drive element 200 in the vertical direction (the j direction as in [Fig.28]) and thus the size of the cleaning device in the vertical direction, which allows for the miniaturization and flattening of the cleaning device.The rotating shaft of the cleaning element 400, in other words, the rotating shaft of the cleaning element 400 in the working state; the vertical direction is the direction of the height of the cleaning device in the operating state.

[0223] In certain embodiments, refer to [Fig. 28], several drive elements 700 are respectively positioned at the ends of the housing 100, which allows for more efficient use of space inside the cleaning device, makes the cleaning device more compact, and enables miniaturization of the cleaning device. Positioning the drive element 700 at the end of the housing 100 facilitates the assembly, maintenance, and repair of the drive element 700 and allows maintenance personnel to inspect the drive element 700 more quickly.

[0224] In certain embodiments, refer to [Fig. 22], a mounting groove 160 for the drive element 700 is formed at the end of the housing. The mounting groove 160 allows for the positioning and alignment of the drive element 700 to ensure that the transmission element 700 is correctly mounted on the housing 100 and to prevent the transmission element 700 from being loose or dislodged.

[0225] In some embodiments, refer to [Fig. 22], a dust collection orifice 150 is formed on the housing 100, and the dust swept by the cleaning element 400 can be collected by the dust collection orifice 150; The dust collection orifice 150 is located between the two cleaning elements 400, which reduces the obstruction of the dust collection orifice 150 by the cleaning elements 400 and allows the cleaned dust to enter the dust collection orifice 150 effectively. The dust collection orifice 150 can be connected to a dust collection component, which can collect impurities such as dust, and the dust collection component can be a dust collection bag or box; A dust extraction component, such as a fan, can be placed on the dust removal component, and the dust extraction component can provide the power needed to remove impurities such as dust.

[0226] In some embodiments, a guide plate is placed on the housing 100 (not shown in the Figure), the guide plate directs the impurities towards the dust removal orifice 150, the guide plate acts as a guide to direct the impurities towards the dust removal orifice 150.

[0227] The embodiment of the present invention provides cleaning equipment comprising said cleaning device.

[0228] It is understood that the cleaning device has a beneficial effect of the above embodiment, and then the cleaning equipment has a corresponding beneficial effect of the above embodiment, the specific embodiment of which may refer to the above embodiment, and the present application does not repeat it.

[0229] Cleaning equipment includes, but is not limited to, sweeping robots, gliding machines and washing and cleaning robots.

[0230] The embodiment of the present invention provides a cleaning system comprising the cleaning device described above and the cleaning equipment described above.

[0231] The cleaning device generally uses the rotation of cleaning elements to perform the cleaning task; however, during the operation of the cleaning elements, hair and other impurities tend to become entangled in them, making them difficult to clean or replace. For example, cleaning devices such as sweeping robots generally use a cleaning brush to clean the floor, and after a certain period of cleaning, hair or dirt tends to become entangled in the cleaning brush, which must then be removed for cleaning or replacement. However, to ensure the proper functioning of the cleaning brush, the brushes involved in the relevant technology are closely linked to the drive system of the sweeping robot, making their disassembly difficult.

[0232] The present invention is described below in conjunction with the accompanying figures and with reference to the specific embodiment:

[0233] The embodiment of the present invention also provides a removable cleaning element mounted on a cleaning device, refer to [Fig.29], [Fig.30] and [Fig.23], in which the cleaning element 400 comprises a free end 420 and a fixed end 430, the fixed end 430 can be removably coupled to the drive mechanism; The cleaning element 400 can rotate under the action of the drive mechanism; And a coupling hole 411 is placed on the cleaning element 400, at least one coupling projection 410 is placed in the coupling hole 411, the coupling projection 410 is removably connected to the drive mechanism.

[0234] In order to disassemble the cleaning element 400 for cleaning or replacement, it is sufficient to disassemble the fixed end 430 of the cleaning element 400, which reduces the workload associated with disassembly and facilitates disassembly while ensuring the normal operation of the cleaning element; A coupling hole 411 is placed in the cleaning element 400, and the coupling projection 410 is removably connected to the drive mechanism, which improves the reliability of the connection between the cleaning element 400 and the drive mechanism by the coupling projection and facilitates the disassembly of the cleaning element 400.

[0235] Said drive mechanism is at least partially threaded into said coupling hole; during assembly, the drive part of the drive mechanism can be threaded into the coupling hole 411 to ensure coaxiality of the cleaning element and the drive mechanism, thus improving the strength of the connection between the cleaning element 400 and the drive mechanism.

[0236] The fixed end 430 of the cleaning element 400 can be removably connected to the drive mechanism; When the cleaning element 400 is in the working state, the drive mechanism can actuate the cleaning element 400 to rotate relative to the housing 100 through the fixed end 430; When the cleaning element 400 is in the disassembled state, it is possible to remove the fixed end 430 directly from the drive mechanism, thus reducing the disassembly operation; As the free end 420 of the cleaning element 400 is suspended, the position of the free end 420 of the cleaning element 400 has a larger operating space, so as to avoid the housing 100 or other parts during disassembly.

[0237] The cleaning element 400 can be a cleaning brush, a mop, etc. Disassembling the cleaning element 400 separately allows the cleaning element 400 to be cleaned separately, without having to disassemble parts such as the drive mechanism, thus reducing the amount of disassembly and assembly work.

[0238] In certain embodiments, refer to [Fig.29], the cleaning element 400 can move relative to the drive mechanism between the first position and the second position; in the case where the cleaning element 400 is in the first position, the cleaning element 400 is connected to the drive mechanism; and in the case where the cleaning element 400 is in the second position, the cleaning element 400 can separate from the drive mechanism.

[0239] When the cleaning element 400 moves from the first to the second position, the cleaning element 400 changes from an operating state to a disassembled state; if the cleaning element 400 is in the first position, the cleaning element 400 is connected to the drive mechanism, so that The cleaning element 400 rotates relative to the housing 100 under the action of the drive mechanism to perform the cleaning work; in the case where the cleaning element 400 is in the second position, the cleaning element 400 can separate from the drive mechanism, so as to facilitate the dismantling of the cleaning element 400 for replacement or cleaning and to prevent the cleaning element 400 from rotating and accidentally injuring an operator during the dismantling of the cleaning element 400, thus improving safety.

[0240] In certain embodiments, refer to [Fig.29], along the axial direction of the cleaning element 400, the cleaning element 400 can move relative to the drive mechanism between the first position and the second position.

[0241] The working state and the disassembled state of the cleaning element 400 can be switched by moving the cleaning element 400 in the axial direction; The cleaning element 400 comprises a free end 420 and a fixed end 430, so that the position of the free end 420 of the cleaning element 400 has excess space for the axial movement of the cleaning element 400, thus switching the working state and the disassembled state.

[0242] In some embodiments, refer to [Fig. 23], there are at least two coupling protrusions 410. Several coupling protrusions 410 may allow the cleaning element 400 to couple closely with the drive mechanism, preventing the cleaning element from separating from the drive mechanism during the working process; The coupling protrusions 410 may be one, two, three or four in number, and the embodiment of the present invention does not specifically limit the number of coupling protrusions 410.

[0243] In certain embodiments, refer to [Fig.29], each coupling projection 410 is in the same position in the axial direction of the cleaning element 400, which can unify the coupling position of each coupling projection 410 and the drive mechanism, so that in case of rotation of the cleaning element 400, each coupling projection 410 can always be coupled with the drive mechanism, improving the flexibility of the assembly between the cleaning element 400 and the drive mechanism.

[0244] In certain embodiments, refer to [Fig. 12], along the axial direction of the cleaning element 400, a first coupling surface 412 and a second coupling surface 413 are formed on opposite sides of the coupling protrusion 410. The first coupling surface 412 and the second coupling surface 413 are suitable for fixing the drive mechanism in order to limit the displacement of the cleaning element 400 relative to the mechanism. drive along the axial direction of the cleaning element 400 during operation.

[0245] In certain embodiments, refer to [Fig. 12], at least one of the first coupling surface 412 and the second coupling surface 413 is perpendicular to the inner wall of the coupling hole 411, which makes it possible to strengthen the connection between the coupling protrusion 410 and the drive mechanism, to further restrict the movement of the cleaning element 400 relative to the drive mechanism along the axial direction of the cleaning element 400, and to ensure the normal operation of the cleaning element 400.

[0246] The embodiment of the present invention provides a cleaning device comprising a drive mechanism and removable cleaning elements as described above.

[0247] It is understood that the removable cleaning elements have the beneficial effect of the above embodiment, and then the cleaning device has a corresponding beneficial effect of the above embodiment, the specific embodiment of which may refer to the above embodiment, and the present application does not repeat it.

[0248] Referring to [Fig.31], the drive mechanism is placed on the housing 100, and the drive mechanism is fixed by the housing 100 to ensure the stability of the drive mechanism during operation; The fixed end 430 of the cleaning element 400 can be removably connected to the drive mechanism, and the drive mechanism plays a supporting and driving role for the cleaning element 400.

[0249] Referring to [Fig. 29], in some embodiments, the drive mechanism comprises a drive element 200 and a support element 600, the support element 600 is connected to the drive shaft of the drive element 200; The support element 600 is placed inside the coupling hole 411, and the support element 600 provides a support force for the cleaning element 400; Through the support element 600, the power of the drive element 200 can be transmitted to the cleaning element 400 to actuate the cleaning element 400 to rotate relative to the housing 100.

[0250] In certain embodiments, refer to Figures 10 to 12, a socket groove 721 is placed on the drive element 200; one end of the support element 600 is threaded through the mating hole 411, and the other end is removably mated inside the socket groove 721. A rotating head 630 can be placed on the support element 600, and the shape of the rotating head 630 can fit the socket groove 721 to improve the firmness of the connection between the drive element 200 and the Support 600; Several projections can be placed on the peripheral side of the rotating head 630, and several depressions can be placed on the inner wall of the slot 721. When the rotating head 630 is inserted into the slot 721, the projections are located within the depressions, preventing the relative rotation of the rotating head 630 and the drive element 200. In the assembled state, the spacing adjustment can be made between the rotating head 630 and the slot 721 to facilitate disassembly, as long as the slot 721 can actuate the rotating head 630 to rotate. The rotating head 630 and the support element 600 can be screwed together or formed as a single piece.The support element 600 serves as a support for the cleaning element 400 and, at the same time, the connection between the cleaning element 400 and the drive element 200 can be made by the support element 600, so that the cleaning element 400 rotates relative to the housing 100 under the drive of the drive element 200.

[0251] It must be understood that in the case where the cleaning element 400 is in the first position, the rotating head 630 is located in the slot groove 721 so that the cleaning element 400 is connected to the drive mechanism and rotates relative to the housing 100 under the action of the drive mechanism to perform the cleaning work; And in the case where the cleaning element 400 moves from the first position to the second position, the rotating head 630 is removed from the slot groove 721 so that, in the case where the cleaning element 400 is in the second position, the cleaning element 400 can separate from the drive mechanism, so as to facilitate the disassembly of the cleaning element 400 for replacement or cleaning.

[0252] In certain embodiments, refer to [Fig.12], the dimension of the support element 600 in the longitudinal direction of the cleaning element 400 (the direction h as in [Fig. 12]) is greater than or equal to half the length of the cleaning element 400, which can provide a greater support span for the cleaning element 400 and reduce bending and deformation of the cleaning element 400, thereby increasing the stability and load-bearing capacity of the cleaning device.

[0253] In certain embodiments, in the case where "a first mating surface 412 and a second mating surface 413 are formed on opposite sides of the mating projection 410," the first mating surface 412 is located at the end of the mating projection 410 furthest from the drive element 200, and a stop element 610 is placed at the end of the support element 600 furthest from the drive element 200. A first stop surface 611 that fits the first mating surface 412 is formed on the element of stop 610; the first coupling surface 412 fits to the first stop surface 611 to limit the slippage of the support element 600 inside the coupling hole 411, preventing the cleaning element 400 from separating from the support element 600 during rotation; the first coupling surface 412 may be a curved surface or an inclined surface, and the embodiment of the present invention does not specifically limit the specific shape of the first coupling surface 412.

[0254] Referring to [Fig. 13], in certain embodiments, a disassembly guide surface 613 is placed on the first stop surface 611, and the disassembly guide surface 613 is used to slide in conjunction with the first mating surface 412 when the cleaning element 400 is disassembled. The relative sliding between the mounting guide surface 612 and the mating hole 411 allows the first mating surface 412 to fit onto the first stop surface 611, thus enabling the support element 600 to be properly mounted in the mating hole 411. The mounting guide surface 612 may be a curved or inclined surface, and the embodiment of the present invention does not specifically limit the specific shape of the mounting guide surface 612.

[0255] Referring to Figures 12 to 14, in certain embodiments, in the case where "a first coupling surface 412 and a second coupling surface 413 are formed on opposite sides of the coupling projection 410", the second coupling surface 413 is located at the end of the coupling projection 410 near the drive element 200. A second stop surface 611 which fits the second coupling surface 413 is formed on the support element 600.The second mating surface 413 fits against the second stop surface to limit the slippage of the support element 600 within the mating hole 411. During assembly, the support element 600 extends into the mounting hole until the second mating surface 413 fits against the second stop surface. The second mating surface 413 then quickly engages with the second stop surface to rapidly lock the mounting position of the support element 600 within the mounting hole, thus improving assembly efficiency. The distance between the first mating surface 412 and the second mating surface 413 is equal to the distance between the first stop surface 611 and the second stop surface, which enhances the robustness of the connection between the support element 600 and the cleaning element 400.

[0256] Refer to Figures 12 to 14; in certain embodiments, a mounting guide surface 612 is formed on the stop element 610. The minimum angle between the mounting guide surface 612 and axial direction of cleaning element 400 is acute.

[0257] Referring to Figures 12 to 14, in certain embodiments, a rebound space 620 of the stop 610 is formed on the support element 600. Under the effect of the force, the relative sliding between the dismantling guide surface 613 and the first coupling surface 412 is achieved, and the stop element 610 retracts into the rebound space 620, allowing the support element 600 to be properly withdrawn from the coupling hole 411.

[0258] Referring to Figures 12 to 14, in some embodiments, the minimum distance between the inner wall of the rebound space 620 and the drive element 200 is less than that between the first coupling surface 412 and the drive element 200, so that the end of the stop element 610 away from the drive element 200 is suspended and the stop element 610 is elastic, which facilitates the return of the stop element 610 into the rebound space 620 after being under the effect of the force.

[0259] Referring to Figures 12 to 15, in some embodiments, a limit portion 640 is placed on the support element 600, the limit portion 640 is located between several stop elements 610, and a gap is formed between the limit portion 640 and the stop elements 610. The stop element 610 retracts in the rebound space 620 until the stop element 610 fits into the limit portion 640, whereby the limit portion 640 can limit the degree of retraction of the stop element 610, preventing excessive bending of the stop element 610 which leads to a fracture.

[0260] In certain embodiments, the stop element 610 is at least partially elastic, facilitating the return of the stop element 610 located in the rebound space 620 to its original position. The stop element 610 may be fully elastic or partially elastic, and the embodiment of the present invention is not particularly limited in this respect.

[0261] In certain embodiments, refer to Figures 12 to 13, at least two stop elements 610 are placed, and each of the stop elements 610 is distributed in the peripheral side direction of the support element 600, facilitating the coupling between the stop elements 610 and the coupling holes 411.

[0262] In certain embodiments, refer to Figures 12 to 13, two stop elements 610 are positioned, and a rebound gap 620 is formed between the opposite sides of the stop elements 610. During the mounting or dismounting of the cleaning element 400, the stop element 610 is bent towards the opposite side under the effect of force, and the rebound gap 620 is located between the two stop elements 610 on opposite sides, so that the stop elements 610 can retract into the gap. rebound 620, allowing the cleaning element 400 to be properly mounted or dismounted; At the same time, the rebound space 620 is placed between the stop elements 610 on opposite sides to maximize the volume of the rebound space 620, making the movement of the stop element 610 more flexible.

[0263] In some embodiments, refer to Figures 12 to 13, a sliding groove 650 is placed on the stop element 610, and the sliding groove 650 can be slidably coupled with the coupling projection 410, which makes the coupling between the cleaning element 400 and the support element 600 smoother thanks to the sliding coupling between the sliding groove 650 and the coupling projection 410.

[0264] In certain embodiments, refer to Figures 12 to 13, in a section perpendicular to the cleaning element 400, the sliding groove 650 and the coupling projection 410 are both curved, which can reduce the sliding resistance between the sliding groove 650 and the coupling projection 410, thus improving the disassembly and assembly efficiency.

[0265] When the cleaning element 400 moves to the second position, as illustrated in [Fig. 29], the cleaning element 400 separates from the drive mechanism. In other words, when the cleaning element 400 enters the disassembled state, it and the drive mechanism decouple, preventing the disassembled cleaning element 400 from rotating relative to the housing 100. This reduces the risk of accidental injury to an operator due to the rotation of the cleaning element 400 during disassembly. The movement of the cleaning element 400 during the switch between the working and disassembled states also allows for rapid connection and separation between the cleaning element 400 and the drive mechanism, further improving operational safety.

[0266] When the cleaning element 400 is in the second position, it can be separated from the drive mechanism, allowing it to be removed for cleaning or replacement. Similarly, when the cleaning element 400 is in the second position, the cleaned or replaced element can be mounted on the drive mechanism to complete the assembly of the cleaning element 400. When the cleaning element 400 is in the second position, it can rotate relative to the drive mechanism and be moved out of the mounting position by a simple rotation, so that the disassembly and assembly operation of the cleaning element 400 is not limited to a narrow mounting position.

[0267] A cleaning device provided by the embodiment of the present invention further includes a support 300, refer to Figures 30 to 31, the cleaning element 400 is mounted on the support 300, the support 300 serves as a support for the cleaning element 400.

[0268] In certain embodiments, refer to Figures 30 to 31, a retention groove 110 of the cleaning element 400 is placed on the housing, and the support 300 rotates in the direction (the direction e as in [Fig. 31]) from the inside of the retention groove 110 to the outside of the retention groove 110. The rotation of the support 300 causes the cleaning element 400 to move from the inside of the retention groove 110 to the outside of the retention groove 110, which reduces the spatial restriction during disassembly to avoid hitting the inner wall of the retention groove 110 or other parts inside the retention groove 110 when disassembling the cleaning element 400, thus reducing the difficulty of disassembling the cleaning element 400.In the case where the cleaning element 400 is in the working state, the cleaning element 400 is partially located inside the retention groove 110; in other words, the retention groove 110 is the mounting position of the cleaning element 400. The retention groove 110 provides physical protection to the cleaning element 400, while the retention groove 110 provides the mechanical support and strength necessary for the cleaning element 400 to rotate into the correct position.

[0269] In some embodiments, a movable shaft 120 is placed on one of the supports 300 and the housing 100, and a coupling groove 321 is placed on the other support 300 and the housing 100. The movable shaft 120 moves within the coupling groove 321 such that the support 300 moves from the first to the second position. For example, referring to Figures 32 to 33, a movable shaft 120 is placed on the housing 100, and a coupling groove 321 is placed on the support 300.
