[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] In addition, the present invention may repeat reference numbers and / or reference letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0048] Cleaning devices typically use rotating cleaning elements to clean; however, during operation, impurities such as hair can easily become entangled in the elements, making them difficult to clean or replace. For example, cleaning devices such as sweeping robots typically use a cleaning brush to clean the floor. After a period of cleaning, the brush can easily become entangled with hair or become contaminated with dirt, necessitating removal for cleaning or replacement. However, to ensure proper operation, the brush is tightly connected to the robot's drive system, making it difficult to remove.

[0049] The present invention will be described below with reference to specific embodiments and in conjunction with the accompanying drawings:

[0050] The first embodiment of the present invention provides a detachable cleaning member, which is installed on a cleaning device. Figure 1 、 Figure 2 and Figure 24 The cleaning member 400 includes a free end 420 and a fixed end 430, and the fixed end 430 is detachably connected to the driving assembly; the cleaning member 400 can rotate under the action of the driving assembly; a matching hole 411 is provided in the cleaning member 400, and at least one matching protrusion 410 is provided in the matching hole 411, and the matching protrusion 410 is detachably connected to the driving assembly.

[0051] The cleaning member 400 can be removed for cleaning or replacement by simply disassembling the fixed end 430 of the cleaning member 400. While ensuring the normal operation of the cleaning member 400, the workload of disassembly can be reduced, making disassembly easier. A mating hole 411 is provided in the cleaning member 400, and the mating protrusion 410 is detachably connected to the drive assembly. The mating protrusion 410 improves the reliability of the connection between the cleaning member 400 and the drive assembly, and facilitates the disassembly of the cleaning member 400.

[0052] During assembly, the driving portion of the driving assembly can be inserted into the matching hole 411 to ensure the coaxiality of the cleaning member and the driving assembly, thereby improving the firmness of the connection between the cleaning member 400 and the driving assembly.

[0053] The fixed end 430 of the cleaning member 400 is detachably connected to the driving assembly; when the cleaning member 400 is in working state, the driving assembly can drive the cleaning member 400 to rotate relative to the shell 100 through the fixed end 430; when the cleaning member 400 is in a disassembled state, the fixed end 430 can be directly detached from the driving assembly, reducing the operation during disassembly; since the free end 420 of the cleaning member 400 is suspended, the free end 420 position of the cleaning member 400 has more operating space, so as to avoid the shell 100 or other components during disassembly.

[0054] The cleaning member 400 can be a cleaning brush, a rolling mop, etc. The cleaning member 400 can be disassembled separately and cleaned separately without removing parts such as a drive assembly, thereby reducing the workload of disassembly and assembly.

[0055] In some embodiments, see Figure 1 The cleaning member 400 can move between a first position and a second position relative to the driving assembly; when the cleaning member 400 is in the first position, the cleaning member 400 is connected to the driving assembly; when the cleaning member 400 is in the second position, the cleaning member 400 can be separated from the driving assembly.

[0056] The cleaning member 400 is switched between the working state and the disassembled state by changing the cleaning member 400 between the first position and the second position; when the cleaning member 400 is in the first position, the cleaning member 400 is connected to the drive assembly, so that the cleaning member 400 rotates relative to the housing 100 under the action of the drive assembly to complete the cleaning work; when the cleaning member 400 is in the second position, the cleaning member 400 can be separated from the drive assembly so that the cleaning member 400 can be removed for replacement or cleaning, and the cleaning member 400 can be prevented from rotating and accidentally injuring the operator when the cleaning member 400 is disassembled, thereby improving safety performance.

[0057] In some embodiments, see Figure 1 , along the axial direction of the cleaning member 400 , the cleaning member 400 can move between a first position and a second position relative to the driving assembly.

[0058] By moving the cleaning member 400 in the axial direction, the working state and the disassembly state of the cleaning member 400 can be switched; the cleaning member 400 includes a free end 420 and a fixed end 430, so that there is extra space at the free end 420 of the cleaning member 400 for the axial movement of the cleaning member 400, thereby switching the working state and the disassembly state.

[0059] In some embodiments, see Figure 24 At least two mating protrusions 410 are provided. Multiple mating protrusions 410 can ensure a tight fit between the cleaning member 400 and the drive assembly, preventing the cleaning member from separating from the drive assembly during operation. The mating protrusions 410 can be provided in one, two, three, or four positions. The present invention does not impose any particular limitation on the number of mating protrusions 410.

[0060] In some embodiments, see Figure 1 , each mating protrusion 410 is at the same position in the axial direction of the cleaning member 400, which can unify the mating positions of each mating protrusion 410 and the driving assembly. When the cleaning member 400 is rotated, each mating protrusion 410 can still cooperate with the driving assembly, thereby improving the assembly flexibility between the cleaning member 400 and the driving assembly.

[0061] In some embodiments, see Figure 13 Along the axial direction of the cleaning member 400, the opposite sides of the mating protrusion 410 form a first mating surface 412 and a second mating surface 413. The first mating surface 412 and the second mating surface 413 are suitable for fixing the driving assembly to limit the movement of the cleaning member 400 relative to the driving assembly along the axial direction of the cleaning member 400 during operation.

[0062] In some embodiments, see Figure 13At least one of the first mating surface 412 and the second mating surface 413 is perpendicular to the inner wall of the mating hole 411, which is beneficial to strengthening the connection between the mating protrusion 410 and the driving assembly, further limiting the movement of the cleaning member 400 relative to the driving assembly along the axial direction of the cleaning member 400, and ensuring the normal operation of the cleaning member 400.

[0063] A second embodiment of the present invention provides a cleaning device, comprising a drive assembly and the above-mentioned detachable cleaning member.

[0064] It can be understood that if the detachable cleaning part has the beneficial effects of the above embodiments, then the cleaning device will correspondingly have the beneficial effects of the above embodiments. Its specific implementation can refer to the above embodiments, and this application will not elaborate on it.

[0065] See also Figure 3 The driving assembly is arranged on the shell 100, and the driving assembly is fixed by the shell 100 to ensure the stability of the driving assembly during operation; the fixed end 430 of the cleaning member 400 is detachably connected to the driving assembly, and the driving assembly supports and drives the cleaning member 400.

[0066] See also Figure 1 In some embodiments, the driving assembly includes a driving member 200 and a support member 600, and the support member 600 is connected to the driving shaft of the driving member 200; the support member 600 is arranged inside the matching hole 411, and the support member 600 provides support force for the cleaning member 400; the power of the driving member 200 can be transmitted to the cleaning member 400 through the support member 600, so as to drive the cleaning member 400 to rotate relative to the shell 100.

[0067] In some embodiments, see Figures 11 to 13 , a fitting groove 721 is provided on the driving member 200; one end of the support member 600 is passed through the matching hole 411, and the other end is detachably connected to the fitting groove 721. A rotating head 630 can be provided on the support member 600, and the shape of the rotating head 630 can match the fitting groove 721 to improve the firmness of the connection between the driving member 200 and the support 600; a plurality of protrusions can be provided on the circumference of the rotating head 630, and a plurality of recesses can be provided on the inner wall of the fitting groove 721. When the rotating head 630 is fitted into the fitting groove 721, the protrusions are located in the recesses to prevent the rotating head 630 and the driving member 200 from rotating relative to each other; in the installed state, the rotating head 630 can be loosely matched with the fitting groove 721, which is convenient for disassembly. It is sufficient that the fitting groove 721 can drive the rotating head 630 to rotate. The rotating head 630 and the support member 600 can be connected by threads or formed in one piece. The support member 600 supports the cleaning member 400 . At the same time, the support member 600 can realize the connection between the cleaning member 400 and the driving member 200 , so that the cleaning member 400 rotates relative to the housing 100 under the drive of the driving member 200 .

[0068] It can be understood that when the cleaning member 400 is in the first position, the rotating head 630 is located in the interlocking groove 721, so that the cleaning member 400 is connected to the drive assembly, so that the cleaning member 400 rotates relative to the shell 100 under the action of the drive assembly to complete the cleaning work; when the cleaning member 400 moves from the first position to the second position, the rotating head 630 is pulled out of the interlocking groove 721, so that when the cleaning member 400 is in the second position, the cleaning member 400 can be separated from the drive assembly so that the cleaning member 400 can be removed for replacement or cleaning.

[0069] In some embodiments, see Figure 13 , the support member 600 is arranged in the length direction of the cleaning member 400 (eg Figure 13 The dimension in the h direction) is greater than or equal to half the length of the cleaning member 400, which can provide a larger support range for the cleaning member 400, reduce the deflection and deformation of the cleaning member 400, and thus increase the stability and carrying capacity of the cleaning device.

[0070] In some embodiments, when "a first mating surface 412 and a second mating surface 413 are formed on opposite sides of the mating protrusion 410", the first mating surface 412 is located at the end of the mating protrusion 410 away from the driving member 200, and a stop member 610 is provided at the end of the support member 600 away from the driving member 200, and a first stop surface 611 is formed on the stop member 610 to fit with the first mating surface 412; the first mating surface 412 and the first stop surface 611 fit together to limit the sliding of the support member 600 inside the mating hole 411, and prevent the cleaning member 400 from separating from the support member 600 during rotation; the first mating surface 412 can be an arc surface or an inclined surface, and the embodiment of the utility model does not specifically limit the specific shape of the first mating surface 412.

[0071] See also Figure 14 In some embodiments, a disassembly guide surface 613 is provided on the first stop surface 611. The disassembly guide surface 613 is configured to slide in conjunction with the first mating surface 412 when the cleaning member 400 is disassembled. The relative sliding between the assembly guide surface 612 and the mating hole 411 allows the first mating surface 412 to mate with the first stop surface 611, thereby allowing the support member 600 to be smoothly assembled into the mating hole 411. The assembly guide surface 612 can be a curved surface or an inclined surface. The specific shape of the assembly guide surface 612 is not particularly limited in the present embodiment.

[0072] See also Figures 13 and 14In some embodiments, when "a first mating surface 412 and a second mating surface 413 are formed on opposite sides of the mating protrusion 410", the second mating surface 413 is located at the end of the mating protrusion 410 close to the driving member 200, and a second stop surface that is in contact with the second mating surface 413 is formed on the support member 600. The contact between the second mating surface 413 and the second stop surface restricts the sliding of the support member 600 within the mating hole 411. During installation, the support member 600 is extended into the assembly hole until the second mating surface 413 and the second stop surface are in contact. The contact between the second mating surface 413 and the second stop surface can quickly lock the installation position of the support member 600 in the assembly hole, thereby 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, thereby improving the stability of the connection between the support member 600 and the cleaning member 400.

[0073] See also Figures 13 and 14 In some embodiments, an assembly guide surface 612 is formed on the stopper 610 , and the minimum angle between the assembly guide surface 612 and the axial direction of the cleaning member 400 is an acute angle.

[0074] See also Figures 13 and 14 In some embodiments, a rebound space 620 for the stopper 610 is formed on the support member 600. When a force is applied, the disassembly guide surface 613 and the first mating surface 412 slide relative to each other, and the stopper 610 retreats to the rebound space 620, allowing the support member 600 to be smoothly removed from the mating hole 411.

[0075] See also Figures 13 and 14 In some embodiments, the minimum distance between the inner wall of the rebound space 620 and the driving member 200 is smaller than the distance between the first mating surface 412 and the driving member 200, so that the end of the stop member 610 away from the driving member 200 is suspended in the air, thereby making the stop member 610 elastic, making it convenient for the stop member 610 to retreat to the rebound space 620 after being subjected to force.

[0076] See also Figures 13 to 15 In some embodiments, a limiting portion 640 is provided on the support member 600. The limiting portion 640 is located between the plurality of stoppers 610, and a gap is formed between the limiting portion 640 and the stoppers 610. The stoppers 610 retract into the rebound space 620 until they abut against the limiting portion 640. The limiting portion 640 can limit the extent of the retraction of the stoppers 610, thereby preventing the stoppers 610 from excessive bending and causing breakage.

[0077] In some embodiments, the stopper 610 is at least partially elastic, which facilitates the return of the stopper 610 located in the rebound space 620 to its original position. The stopper 610 can be fully elastic or partially elastic, which is not particularly limited in the present embodiment.

[0078] In some embodiments, see Figures 13 and 14 At least two stoppers 610 are provided, and each stopper 610 is distributed in the circumferential direction of the support member 600 to facilitate the cooperation between the stopper 610 and the cooperation hole 411.

[0079] In some embodiments, see Figures 13 and 14 Two stoppers 610 are provided, and a rebound space 620 is formed between the stoppers 610 on opposite sides. During the installation or removal of the cleaning member 400, the stoppers 610 are forced to bend toward the opposite side. The rebound space 620 is located between the two stoppers 610 on opposite sides. Therefore, the stoppers 610 can be avoided into the rebound space 620, allowing the cleaning member 400 to be smoothly installed or removed. At the same time, the rebound space 620 is provided between the stoppers 610 on opposite sides to maximize the volume of the rebound space 620, making the movement of the stoppers 610 more flexible.

[0080] In some embodiments, see Figures 13 and 14 The stopper 610 has a slide groove 650, which can slide with the mating protrusion 410. Through the sliding cooperation between the slide groove 650 and the mating protrusion 410, the cooperation between the cleaning member 400 and the supporting member 600 becomes smoother.

[0081] In some embodiments, see Figures 13 and 14 In the cross section perpendicular to the cleaning member 400, the slide groove 650 and the matching protrusion 410 are both arc-shaped, which can reduce the sliding resistance between the slide groove 650 and the matching protrusion 410, thereby improving the disassembly and assembly efficiency.

[0082] When the cleaning member 400 moves to the second position, Figure 1 As shown, the cleaning member 400 is separated from the drive assembly, that is, when the cleaning member 400 enters the disassembled state, the cleaning member 400 and the drive assembly are disengaged, thereby preventing the cleaning member 400 from rotating relative to the housing 100 in the disassembled state, and reducing the risk of the cleaning member 400 accidentally injuring the operator when the cleaning member 400 is disassembled. Through the movement of the cleaning member 400, while achieving the switching between the working state and the disassembled state of the cleaning member 400, it is also possible to quickly connect and disconnect the cleaning member 400 and the drive assembly, thereby improving the safety of operation.

[0083] When the cleaning member 400 is in the second position, the cleaning member 400 can be separated from the drive assembly and can be removed for cleaning or replacement. Similarly, when the cleaning member 400 is in the second position, the cleaned cleaning member 400 or the replaced cleaning member 400 can be installed on the drive assembly to complete the installation of the cleaning member 400. When the cleaning member 400 is in the second position, the cleaning member 400 can be rotated relative to the drive assembly. With a simple rotation, the cleaning member 400 can be moved outside the installation position, so that the removal operation of the cleaning member 400 is not limited to a narrow installation position.

[0084] The cleaning device provided in the embodiment of the present invention further includes a bracket 300. Figures 2 to 3 The cleaning member 400 is installed on the bracket 300 , and the bracket 300 supports the cleaning member 400 .

[0085] In some embodiments, see Figures 2 to 3 The housing is provided with a receiving groove 110 for the cleaning member 400, and the bracket 300 is arranged in a direction from the inside of the receiving groove 110 to the outside of the receiving groove 110 (eg Figure 3 The bracket 300 rotates in the direction e) of the receiving groove 110. The rotation of the bracket 300 allows the cleaning member 400 to move from inside the receiving groove 110 to outside the receiving groove 110, reducing spatial restrictions during disassembly, preventing the cleaning member 400 from hitting the inner wall of the receiving groove 110 or other parts inside the receiving groove 110 when disassembling, and reducing the difficulty of disassembly. When the cleaning member 400 is in the working state, the cleaning member 400 is partially located inside the receiving groove 110, that is, the receiving groove 110 is the installation position of the cleaning member 400. The receiving groove 110 provides physical protection for the cleaning member 400. At the same time, the receiving groove 110 provides the cleaning member 400 with the necessary mechanical support and robustness, allowing the cleaning member 400 to rotate in the appropriate position.

[0086] In some embodiments, one of the bracket 300 and the housing 100 is provided with a movable shaft 120, and the other is provided with a matching groove 321; the movable shaft 120 moves inside the matching groove 321, so that the bracket 300 switches between the first position and the second position. Figures 4 and 5 A movable shaft 120 is provided on the housing 100 , and a matching groove 321 is provided on the bracket 300 .

[0087] By the movement of the movable shaft 120 in the matching groove 321, the relative displacement of the bracket 300 and the shell 100 is achieved, which facilitates the disassembly and assembly of the cleaning member 400; during the rotation of the bracket 300, the movable shaft 120 is restricted to the inside of the matching groove 321, that is, the bracket 300 and the shell 100 always maintain a matching relationship; by rotating the cleaning member 400, the cleaning member 400 can be moved out of the installation position to facilitate the disassembly of the cleaning member 400; when the cleaning member 400 moves to the first position, the cleaning member 400 installed on the bracket 300 can be moved to the installation position, so that the disassembled cleaning member 400 can be quickly and accurately installed in the installation position, thereby speeding up the installation speed of the cleaning member 400.

[0088] Of course, in other embodiments, the movable shaft 120 may be provided on the bracket 300 and the matching groove 321 may be provided on the housing 100, and the embodiment of the present utility model does not specifically limit this.

[0089] In some embodiments, see Figure 6 , the matching groove 321 is along the direction of the rotation axis of the cleaning member 400 (such as Figure 6 f direction in the middle), so that when the movable shaft 120 moves inside the matching groove 321, the cleaning member can rotate around the movable shaft 120. When the cleaning member is arranged obliquely upward, the cleaning members on the left and right sides will not interfere with each other, so that the cleaning member 400 located on the bracket 300 can be close to or away from the driving member 200, so that the cleaning member 400 can be connected to or separated from the driving shaft of the driving member 200.

[0090] In some embodiments, see Figure 6 The end of the matching groove 321 has an arc-shaped inner wall to fit the arc-shaped outer surface of the movable shaft 120, making it convenient for the bracket 300 to rotate around the movable shaft 120 as the rotation center.

[0091] In some embodiments, see Figures 6 and 7 The matching groove 321 is at an end away from the cleaning member 400 and faces a direction away from the housing 100 (eg Figure 7 g direction) is inclined so that the matching groove 321 can match the rotation path of the bracket 300 at the end away from the cleaning member 400, making the rotation process of the bracket 300 smoother.

[0092] In some embodiments, see Figures 6 and 7The bracket 300 includes a base 310 and a connecting ear 320. The connecting ear 320 is protruded from the base 310, and the matching groove 321 is provided on the connecting ear 320. The position of the matching groove 321 can be quickly locked during installation, thereby speeding up the installation speed. In addition, compared with directly providing the matching groove 321 on the base 310, the embodiment of the utility model protrudes the connecting ear 320 on the base 310, which is beneficial for the bracket 300 to avoid the shell 100 or other components installed on the shell 100 when rotating, so that the rotation of the bracket 300 is relatively flexible.

[0093] In some embodiments, see Figures 7 and 8 The housing 100 is formed with a fixing groove 130 for the connecting ear 320 to confine the connecting ear 320 within the fixing groove 130, thereby reducing shaking of the connecting ear 320 when the bracket 300 rotates and improving the stability of the bracket 300's rotation. The movable shaft 120 is disposed through the sidewall of the fixing groove 130. When the connecting ear 320 moves within the fixing groove 130, the movable shaft 120 moves within the mating groove 321, thereby achieving mating between the movable shaft 120 and the mating groove 321. For example, the fixing groove 130 has a first sidewall 131 and a second sidewall 132 disposed opposite each other. The connecting ear 320 is located between the first sidewall 131 and the second sidewall 132, and the rotating shaft passes through the first sidewall 131, the mating groove 321, and the second sidewall 132 in sequence. When the connecting ear 320 moves between the first sidewall 131 and the second sidewall 132, the movable shaft 120 and the mating groove 321 undergo relative displacement, thereby achieving switching of the bracket 300 between the first position and the second position. Two connecting ears 320 can be provided to ensure the stability of the rotation of the bracket 300. The embodiment of the present utility model does not specifically limit the number of the connecting ears 320.

[0094] In some embodiments, please participate Figure 9 The housing 100 is provided with a positioning slot 140, and the bracket 300 is provided with a positioning portion 360. When the bracket 300 is in the first position, the positioning portion 360 is at least partially located within the positioning slot 140. The positioning slot 140 restricts the movement of the positioning portion 360, allowing the bracket 300 to remain in the first position and ensure the normal operation of the cleaning member 400. The positioning portion 360 can be partially or completely located within the positioning slot 140, as long as the positioning slot 140 can restrict the movement of the positioning portion 360. The shape of the positioning slot 140 can match the positioning portion 360 to better secure the positioning portion 360.

[0095] The positioning portion 360 is connected to the base 310, and the positioning groove 140 can be connected to the fixing groove 130, which is convenient for processing. There are two positioning portions 360, and the two positioning portions 360 can improve the fixing effect of the bracket 300.

[0096] In some embodiments, please participate Figure 9 The positioning groove 140 includes a first guide surface 141, through which the bracket 300 slides out of the positioning groove 140. The relative sliding between the first guide surface 141 and the positioning portion 360 can reduce the difficulty of the bracket 300 sliding out of the positioning groove 140, which is conducive to the bracket 300 switching from the first position to the second position; the first guide surface 141 can be an arc surface or an inclined surface, and the embodiment of the utility model does not specifically limit the specific shape of the first guide surface 141; the first guide surface 141 is arranged on the side of the positioning groove 140 away from the rotation center of the bracket 300, that is, the first guide surface 141 is arranged on the side of the positioning groove 140 away from the matching groove 321.

[0097] In some embodiments, please participate Figure 9 The positioning portion 360 is provided with a second guide surface 330, through which the bracket 300 slides out of the positioning slot 140. The relative sliding between the second guide surface 330 and the positioning slot 140 can reduce the difficulty of the bracket 300 sliding out of the positioning portion 360, which facilitates the switching of the bracket 300 from the first position to the second position. The second guide surface 330 can be an arcuate surface or an inclined surface. The embodiment of the utility model does not specifically limit the specific shape of the second guide surface 330. The second guide surface 330 is provided on the side of the positioning portion 360 away from the rotation center of the bracket 300, that is, the second guide surface 330 is provided on the side of the positioning portion 360 away from the movable axis 120.

[0098] In some embodiments, please participate Figure 9 There is a first guide surface 141 on the positioning groove 140, and a second guide surface 330 is provided on the positioning portion 360. The relative sliding between the first guide surface 141 and the second guide surface 330 can reduce the difficulty of the bracket 300 sliding out of the positioning groove 140, which is conducive to the bracket 300 switching from the first position to the second position.

[0099] In some embodiments, see Figure 10 The cleaning device further includes a cover 500 that covers at least a portion of the positioning slot 140. The cover 500 covers the positioning slot 140, thereby confining the positioning portion 360 within the positioning slot 140 and maintaining the bracket 300 in the first position, thereby ensuring the normal operation of the cleaning member 400. The cover 500 can cover all or part of the positioning slot 140, as long as the cover 500 can prevent the positioning portion 360 from sliding out of the positioning slot 140. Before removing the cleaning member 400, the cover 500 can be separated from the positioning slot 140, the positioning portion 360 can be slid out of the positioning slot 140, and the bracket 300 can be rotated to remove the cleaning member 400 from the bracket 300.

[0100] In some embodiments, see Figure 10 An extension portion 170 is provided at the notch of the accommodating groove 110, the cover body 500 covers the accommodating groove 110, and the cover body 500 is connected to the extension portion 170 to complete the connection between the cover body 500 and the shell 100; a working window 510 is generally opened on the cover body 500, and part of the cleaning member 400 extends out of the working window 510 for cleaning work; in order to facilitate processing, the extension portion 170 is an extension plate.

[0101] In some embodiments, see Figure 15 The bracket 300 is provided with a connecting portion 340, which is mounted on the outside of the support member 600. The support member 600 allows the cleaning member 400 to be mounted on the bracket 300. The connecting portion 340 is mounted on the outside of the support member 600 to support the support member 600, ensuring that the support member 600 remains stable during operation. The support member 600 can rotate relative to the connecting portion 340, preventing the bracket 300 from rotating with the rotation of the support member 600. To enable relative rotation between the support member 600 and the bracket 300, a bearing 350 can be installed between the support member 600 and the bracket 300, allowing the support member 600 to rotate smoothly relative to the bracket 300. The connecting portion 340 can be connected to the base 310.

[0102] In some embodiments, see Figure 16 , there are at least two cleaning members 400. Providing multiple cleaning members 400 can increase the effective cleaning area and improve the cleaning effect of the cleaning device; the cleaning member 400 has a fixed end 430 and a free end 420. The fixed end 430 of the cleaning member 400 is connected to the shell 100 through the bracket 300. When disassembling the cleaning member 400, only the fixed end 430 of the cleaning member 400 needs to be disassembled, thereby reducing the workload of disassembly; the free end 420 of the cleaning member 400 extends toward another cleaning member 400, which can reduce the impact on the other cleaning member 400 when disassembling one of the cleaning members 400, which is conducive to maintaining the independence of each cleaning member 400.

[0103] The driving member 200 is in transmission connection with each cleaning member 400, and the driving member 200 is used to drive the multiple cleaning members 400 to rotate relative to the housing 100. By having a single driving member 200 drive multiple cleaning members 400 to rotate relative to the housing 100, the number of driving members 200 can be reduced, thereby reducing the space occupied by the driving members 200, making the layout of the cleaning device more compact, and thus minimizing the size of the cleaning device. Using a single driving member 200 to drive multiple cleaning members 400 can reduce the total weight of the driving member 200, making it easier to move the cleaning device.

[0104] The embodiment of the present invention drives multiple cleaning members 400 to work through a single driver 200, avoiding the need to configure a separate driver 200 for each cleaning member 400, thereby reducing equipment procurement costs. Maintaining a single driver 200 generally requires fewer spare parts and less maintenance time than maintaining multiple drivers 200, so it is more economical to provide a single driver 200. The unified use of a single driver 200 also allows multiple cleaning members 400 to be controlled, which is beneficial for fault diagnosis of the cleaning device and facilitates timely detection and handling of problems. In addition, using a single driver 200 to drive multiple cleaning members 400 can reduce energy loss, improve overall energy efficiency, optimize energy utilization, and reduce energy consumption.

[0105] During operation of the cleaning device, the multiple cleaning elements 400 typically move synchronously. Therefore, using a single drive element 200 ensures that all cleaning elements 400 operate synchronously, improving the operating efficiency of the cleaning device. Using a single drive element 200 also facilitates centralized control and monitoring of the multiple cleaning elements 400, improving the automation and response speed of the cleaning device.

[0106] See also Figure 16 The embodiment of the present invention further includes a plurality of transmission members 700 , which are connected to the cleaning members 400 accordingly; the transmission members 700 are driven by the driving member 200 to drive the corresponding cleaning members 400 to rotate.

[0107] The power generated by the driving member 200 can be transmitted to each cleaning member 400 through the transmission member 700, so that each cleaning member 400 rotates relative to the shell 100, thereby realizing that multiple cleaning members 400 are driven to work by one driving assembly; the transmission member 700 can adopt multiple gears or pulleys of different diameters to adjust the rotation speed and achieve the effect of regulating the speed; different transmission members 700 can adopt different reduction ratios, so that multiple cleaning members 400 can rotate at different speeds.

[0108] See also Figure 17, the embodiment of the present utility model also includes a linkage member 800, which connects at least two transmission members 700. At least two transmission members 700 are connected through the linkage member 800 to achieve synchronous movement of multiple transmission members 700; the output shaft of the driving member 200 is connected to the linkage member 800, and multiple transmission members 700 can be driven synchronously by driving the linkage member 800. By connecting multiple transmission members 700 through the linkage member 800, the driving member 200 only needs to be connected to the linkage member 800 to drive the multiple transmission members 700 to rotate. The driving member 200 does not need to be directly connected to the multiple transmission members 700, so that the installation position of the driving member 200 is more flexible, which is beneficial to the overall layout of the cleaning device and makes the structure of the cleaning device more compact. The linkage member 800 can be a rod body, and the multiple transmission members 700 can be distributed in the length direction of the linkage member 800 (such as Figure 17 In the i direction), the rod-shaped linkage member 800 can save space.

[0109] In other embodiments, the output shaft of the driving member 200 can be connected to at least one transmission member 700, and the driving member 200 can drive one of the transmission members 700, and then drive another transmission member 700 to move through the linkage member 800, so as to achieve the effect of one driving assembly driving multiple transmission members 700 to move, thereby achieving a single driving assembly driving multiple cleaning members 400 to rotate relative to the housing 100. The output shaft of the driving member 200 can be connected to one transmission member 700, or it can be connected to two, three, or four transmission members 700 to ensure the stability of the rotation of the cleaning member 400, and this is not limited in the embodiments of the present invention.

[0110] In other embodiments, the output shaft of the driving member 200 may be connected to the linkage member 800 and at least one transmission member 700 to improve the stability of power transmission and ensure stable rotation of the cleaning member 400. Generally, the driving member 200 is a motor.

[0111] In some embodiments, see Figure 18 The transmission member 700 includes an input wheel 710 and an output wheel 720. The output wheel 720 is connected to the output shaft of the driving member 200, and the input wheel 710 and the output wheel 720 are coupled. Through the coupling of the output wheel 720 and the input wheel 710, the driving member 200 drives the output wheel 720 to rotate.

[0112] In some embodiments, see Figures 18 and 19The transmission member 700 includes a first transmission member 730, which includes a first input wheel 731 and two first output wheels 732. The first input wheel 731 is connected to the drive shaft of the driving member 200, one of the first output wheels 732 is connected to the corresponding cleaning member 400, and the other first output wheel 732 is connected to the linkage member 800. The first transmission member 730 is connected to the first output wheel 732 through the drive shaft of the driving member 200, thereby realizing the connection between the first transmission member 730 and the driving member 200. The linkage member 800 and the cleaning member 400 corresponding to the first transmission member 730 are then driven to rotate by the first transmission member 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 member 400 to rotate. At the same time, the first input wheel 731 can also drive other cleaning members 400 to rotate through the linkage member 800, thereby realizing the rotation of multiple cleaning members 400 relative to the housing 100. In other embodiments, the first input wheel 731 may also be coupled to the two first output wheels 732 to drive the two first output wheels 732 to rotate.

[0113] See also Figures 19 to 20 The transmission member 700 may also include a second transmission member 740, the second transmission member 740 includes a second input wheel 741 and a second output wheel 742, the second input wheel 741 is connected to the linkage member 800, the second output wheel 742 is connected to the corresponding cleaning member 400, and the second input wheel 741 and the second output wheel 742 are coupled to each other, and the corresponding cleaning member 400 is rotated through the coupling of the second output wheel 742 and the second input wheel 741.

[0114] See also Figure 21 , wherein the engaging groove 721 can be provided on the output wheel 720 so that the output wheel 720 drives the corresponding cleaning member 400 to rotate.

[0115] In some embodiments, see Figure 22There are two transmission members 700, which are located on opposite sides of the shell 100; one end of the linkage member 800 is connected to one of the transmission members 700, and the other end is connected to the other transmission member 700. The transmission members 700 are located on opposite sides of the shell 100, which can reduce energy loss when the linkage member 800 transmits power, and at the same time is beneficial for the linkage member 800 to ensure that the transmission members 700 on both sides of the shell 100 achieve synchronous movement. By connecting the transmission members 700 located on opposite sides of the shell 100 through the linkage member 800, the force and torque can be more evenly distributed throughout the cleaning device, which is beneficial to reducing stress concentration and extending the service life of the transmission member 700 and the linkage member 800. The transmission members 700 are located on opposite sides of the shell 100, reducing the risk of vibration and imbalance caused by the unilateral transmission member 700, making the operation of the entire cleaning device more stable and reliable.

[0116] In some embodiments, see Figure 22 , the output shaft of the driving member 200 is arranged along the direction of the rotation axis of the cleaning member 400. Since the driving member 200 is generally long and its length direction is the extension direction of the output shaft of the driving member 200, the output shaft of the driving member 200 is arranged along the direction of the rotation axis of the cleaning member 400 to reduce the vertical direction (such as Figure 22 The vertical direction is the height of the cleaning device in the working state.

[0117] In some embodiments, see Figure 22 The multiple transmission members 700 are respectively arranged at the ends of the housing 100, which can more efficiently utilize the space inside the cleaning device, make the cleaning device more compact, and facilitate the miniaturization of the cleaning device. The arrangement of the transmission members 700 at the ends of the housing 100 makes the installation, maintenance, and inspection of the transmission members 700 more convenient, and maintenance personnel can more quickly check the transmission members 700.

[0118] In some embodiments, see Figure 23 The end of the housing 100 forms a mounting groove 160 for the transmission member 700. The mounting groove 160 can provide positioning and alignment functions for the transmission member 700, ensuring that the transmission member 700 is correctly installed on the housing 100 and preventing the transmission member 700 from loosening or falling out of position.

[0119] In some embodiments, see Figure 23The housing 100 is formed with a dust collection port 150, through which dust swept by the cleaning members 400 can be collected. The dust collection port 150 is located between the two cleaning members 400, which can reduce the obstruction of the dust collection port 150 by the cleaning members 400, allowing the swept dust to enter the dust collection port 150 smoothly. The dust collection port 150 can be connected to a dust collection component, which can collect dust and other impurities. The dust collection component can be a dust collection bag or a dust collection box. A dust collection component, such as a fan, can be provided on the dust collection component to provide power for the flow of dust and other impurities.

[0120] In some embodiments, a guide plate (not shown in the figure) is provided on the housing 100 , and the guide plate is suitable for guiding impurities to the dust collection port 150 . The guide plate plays a guiding role and can guide the impurities to the dust collection port 150 .
