[0002] Cleaning equipment, such as sweepers, mops, combined sweepers and mops, and floor scrubbers, are increasingly common in modern households due to their excellent cleaning performance and efficiency. To address the issue of edge cleaning, which often prevents cleaning equipment from reaching certain recesses and gaps along edges, existing technologies offer cleaning assemblies capable of extending the cleaning element relative to the machine body. In normal cleaning mode, this design maintains the cleaning element in a retracted position. However, in edge cleaning mode, the cleaning element can be adjusted to an extended position, allowing it to reach recesses and gaps along edges, improving edge cleaning effectiveness.

[0044] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0047] The present invention provides a cleaning device and a cleaning assembly 100 thereof. The specific form of the cleaning device is not limited, and it may be, for example, a handheld cleaning device or a self-propelled cleaning device. The cleaning device includes a body, and the cleaning assembly 100 is adapted to be mounted on the body of the cleaning device so as to move with the body to clean the surface to be cleaned. The cleaning device may be a sweeper, mop, sweeper-and-mop, or floor scrubber, and the surface to be cleaned may include, but is not limited to, floors, walls, countertops, windows, and furniture surfaces.

[0048] It is understood that when the cleaning device is a self-propelled cleaning device, it may further include a travel drive mechanism for driving the body to automatically travel along the surface to be cleaned, and the body may also be equipped with auxiliary travel components such as rollers. The cleaning assembly 100 specifically includes a cleaning member, which refers to a member that directly contacts the surface to be cleaned to achieve friction cleaning of the surface to be cleaned. The specific type of the cleaning member depends on the specific type of cleaning device, for example, it may be a cleaning roller brush, a cleaning rag disc, etc. It is understood that in an optional embodiment, the cleaning member may also be configured to be driven to rotate automatically to improve cleaning efficiency.

[0049] In this embodiment, the cleaning member can be adjusted relative to the machine body by the specific design of the cleaning assembly 100. In this way, the cleaning member has a retracted position relatively close to the machine body (e.g. Figures 1 to 3 ), and an extended position relatively far from the body (as shown Figures 4 to 6As shown). It can be understood that in this embodiment, when the cleaning device is in normal cleaning mode, it is suitable for cleaning the middle area of ​​a large surface to be cleaned, and the cleaning member should be switched to the retracted position. When the cleaning device is in edge cleaning mode, it is suitable for cleaning along the edge of the surface to be cleaned. At this time, the cleaning member should be switched to the extended position, so that it can penetrate deeper into the recessed areas and gaps at the edge of the surface to be cleaned during edge cleaning, thereby significantly improving the edge cleaning efficiency and cleaning effect of the cleaning device.

[0050] See also Figures 1 to 12 The utility model provides a cleaning component 100, which specifically includes a frame 10, an active group 20, a driven group 30 and a cleaning mechanism 40, wherein the frame 10 is suitable for being connected to the body of the cleaning equipment to achieve support for the overall structure of the cleaning component 100. The active group 20 includes an active member 21 movably mounted on the frame 10, and may also include a drive motor 22 for providing a power source for the active member 21, and the drive motor 22 may also be mounted on the frame 10. Preferably, the drive motor 22 is drive-connected to the active member 21 to drive the active member 21 to rotate. The driven group 30 includes a driven member 31 movably mounted on the frame 10, and the driven member 31 is drive-connected to the active member 21 so that the active member 21 drives the driven member 31 to reciprocate relative to the frame 10. It is understood that the specific method for achieving reciprocating motion of the driven member 31 relative to the frame 10 can be that when the drive motor 22 rotates in the forward direction, the driven member 31 is driven to move in a first direction, and when the drive motor 22 rotates in the reverse direction, the driven member 31 is driven to move in a second direction opposite to the first direction. It should be noted that the forward rotation can be either clockwise or counterclockwise rotation of the motor shaft of the drive motor 22, while the reverse rotation is rotation of the motor shaft in a direction opposite to the forward direction.

[0051] The cleaning mechanism 40 is mounted on the driven group 30, and the cleaning mechanism 40 includes a cleaning member, which is linked to the movement of the driven member 31 to have a reciprocating stroke relative to the frame 10, wherein the above-mentioned retracted position and extended position should be respectively arranged at both ends of the reciprocating path of the cleaning member. That is, when the drive motor 22 rotates forward, the active member 21 drives the driven member 31 to move in a first direction, and the cleaning member is driven to move from the retracted position to the extended position. When the drive motor 22 rotates reversely, the active member 21 drives the driven member 31 to move in a second direction, and the cleaning member is driven to move from the extended position to the retracted position. It will be understood that in a preferred embodiment, the cleaning mechanism 40 may further include a drive device 41 and a drive shaft 42, the drive device 41 being used to drive the drive shaft 42 to rotate, and the cleaning member being mounted on the drive shaft 42 to rotate with the drive shaft 42. In this way, the drive device 41 drives the cleaning member to automatically rotate during cleaning work to improve the cleaning effect. The driving device 41 may include a motor, a reducer and other structures, and can be directly or indirectly connected to the driven member 31 to move in conjunction with the driven member 31 .

[0052] Among them, see Figures 3 to 8 The active member 21 is provided with a first engaging portion 211, and the driven member 31 is provided with a second engaging portion 311. When the cleaning member is in the retracted position, the first engaging portion 211 and the second engaging portion 311 are interlocked, so that when no driving force is applied to the active member 21, the locking force between the first engaging portion 211 and the second engaging portion 311 can keep the active member 21 stationary. At this time, when the external force is not greater than the above-mentioned locking force, the driven member 31 and the active member 21 remain relatively stationary, and the active member 21 and / or the driven member 31 will not suddenly move under the action of the external force, causing the cleaning assembly 100 to shake significantly. Conversely, when a driving force is applied to the active member 21, the locking force between the first engaging portion 211 and the second engaging portion 311 is overcome by the driving force applied by the active member 21, driving the driven member 31 to move the cleaning member to the extended position. In other words, in this embodiment, the mechanical locking structure between the active member 21 and the driven member 31 is utilized to enhance the overall stability of the cleaning assembly 100, so that in normal cleaning mode, the cleaning member can be more stably maintained in the retracted position, and the driven member 31 and the active member 21 remain relatively stationary. This prevents the cleaning member from causing large displacement, unusual noise, or even unpredictable shaking of the cleaning member that makes it impossible to determine its cleaning range, resulting in some areas being missed and not being cleaned properly.

[0053] Further, please refer to Figure 3 、 Figure 7 and Figure 8The active member 21 is a driving gear rotatably mounted on the frame 10, and the driven member 31 is a driven gear rotatably mounted on the frame 10. The first engaging portion 211 is a first engaging tooth provided on the driving gear, and the second engaging portion 311 is a second engaging tooth provided on the driven gear. When the cleaning member is in the retracted position, the first engaging tooth and the second engaging tooth interlock with each other. In this way, the driven assembly 30 is driven by the meshing active and driven gears. When the drive motor 22 drives the active gear to rotate in the forward direction, the driven gear rotates in the first direction, and the cleaning member is driven to move from the retracted position to the extended position. When the drive motor 22 drives the active gear to rotate in the reverse direction, the driven gear rotates in the second direction, and the cleaning member is driven to move from the extended position to the retracted position. It should be noted that the drive motor 22 itself can also be designed to have a certain self-locking force, which can also play a certain role in preventing the active gear from rotating in the forward or reverse direction under the action of external forces when the cleaning member is in the retracted position. In this embodiment, the locking force between the first locking tooth and the second locking tooth is greater than the self-locking force, so as to provide a more stable support for the cleaning member.

[0054] The structure for achieving locking by the first engaging tooth and the second engaging tooth can be designed as required. In this embodiment, please refer to Figure 7 and Figure 8 The first engaging tooth is formed with a first engaging surface 212, which is parallel to the tangent direction of the driving gear. The second engaging tooth is formed with a second engaging surface 312. When the first engaging tooth and the second engaging tooth are locked with each other, the first engaging surface 212 and the second engaging surface 312 are in contact with each other. In this way, when the first engaging tooth and the second engaging tooth are locked with each other, there is sufficient locking force. When the drive motor 22 rotates in the forward direction and provides sufficient driving force, the first engaging tooth and the second engaging tooth can also be smoothly released, so that the driving gear drives the driven gear to rotate in the second direction, driving the cleaning element to move to the extended position.

[0055] Based on the above examples, please continue to refer to Figure 9 and Figure 11The driven group 30 also includes a swinging member 32, which is rotatably mounted on the frame 10 and is arranged in linkage with the driven gear. The swinging member 32 has a linkage end 321 that cooperates with the driven gear and an actuating end 322 that rotates around the linkage end 321. The cleaning component 100 is fixed to the actuating end 322, so that when the linkage end 321 moves in linkage with the driven gear, the actuating end 322 rotates accordingly, driving the cleaning component to switch between the retracted position and the extended position. In this embodiment, the swinging member 32 that is linked to the driven gear is used to drive the cleaning component to swing relative to the frame 10, thereby switching between the retracted position and the extended position. The structure is compact, simple, reliable, and easy to implement. Specifically, when the driven gear rotates in the second direction, the linkage end 321 acting on the swinging member 32 drives the cleaning component 100 on its actuating end 322 to swing in the same direction, causing the cleaning component to move from the retracted position to the extended position.

[0056] Further, please refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6 The cleaning assembly 100 further includes an elastic member 50, which is disposed between the swing member 32 and the frame 10. During the active stroke of the active member 21 driving the cleaning member to move from the extended position to the retracted position, the elastic member 50 stores energy. During the active stroke of the active member 21 driving the cleaning member to move from the retracted position to the extended position, the elastic member 50 provides a restoring force. In this embodiment, the elastic member 50 provides a portion of the driving force during the switching process of the cleaning member from the retracted position to the extended position, reducing the driving burden of the drive motor 22 in releasing the lock. Furthermore, when the cleaning member switches to the extended position, it is elastically supported and maintained in the extended position. That is, when the driving gear and the driven gear remain relatively stationary, when the cleaning member is subjected to an external force, it can overcome the elastic force of the elastic member 50 and move from the extended position to the retracted position. When the external force is removed, the cleaning member can return to the extended position under the action of the elastic restoring force. Specifically, in the edge cleaning mode of the cleaning device, the cleaning member is elastically supported by the elastic member 50 and maintained in the extended position. At this time, when the cleaning member is squeezed by an obstacle, the elastic member 50 can play a buffering role on the active group 20 and the driven group 30, preventing the cleaning component 100 from being damaged by the collision with the obstacle and the rigid collision with the body. In addition, the elastic member 50 also enables the cleaning member to always maintain contact with the edge structure, which can better clean the edge and corner structure of the surface to be cleaned and ensure the cleaning effect.

[0057] Preferably, the elastic member 50 is a tension spring, one end of which is connected to the frame 10 and the other end is connected to the actuating end 322. In this way, the tension spring plays a good elastic supporting role for the cleaning mechanism 40 and is exposed to the outside of the active group 20, the driven group 30 and the cleaning mechanism 40, which is convenient for maintenance and replacement. Figure 1 and Figure 4 Shown, can be formed with the guide channel extending along the tension spring direction on the top plate 11 of frame 10, to protect and to the tension spring guiding. Simultaneously, the two ends of the tension spring can stretch out from the two ends of the guide channel, so that overhaul and replacement.

[0058] Further, see Figures 9 to 11 The driven assembly 30 further includes a rotating shaft 33 rotatably mounted on the frame 10. A driven gear is rotatably sleeved on the rotating shaft 33. The swinging member 32 is coaxially connected to the rotating shaft 33. The linkage end 321 and the actuating end 322 are located on either side of the rotating shaft 33 in the radial direction, that is, the swinging member 32 rotates about the rotating shaft 33. The driven gear is a sector gear. A first abutting portion 341 is provided on one side of the sector gear in the circumferential direction. The actuating end 322 is provided with a second abutting portion 342 facing the first abutting portion 341. Specifically, the second abutting portion 342 and the first abutting portion 341 are arranged sequentially in a first direction. During the active travel of the cleaning member from the retracted position to the extended position, the second abutting portion 342 rotates toward the first abutting portion 341. During the active travel of the cleaning member from the extended position to the retracted position, the first abutting portion rotates toward the second abutting portion 342. In this embodiment, during the movement of the cleaning member from the retracted position to the extended position, the elastic member 50 pulls the cleaning mechanism 40, driving the swinging member 32 to rotate in the first direction, and the second abutting portion 342 pushes the first abutting portion 341 to move, driving the driven gear to rotate in the first direction. At the same time, the driving gear is driven by the drive motor 22 to rotate forward, driving the driven gear to rotate in the first direction. During the movement of the cleaning member from the extended position to the retracted position, the drive motor 22 rotates in the reverse direction, driving the driving gear to rotate in the reverse direction, driving the driven gear to rotate in the second direction, and the first abutting portion 341 pushes the second abutting portion 342 to move, causing the swinging member 32 to rotate in the second direction. During this process, the tension spring is stretched and elastically stores energy.

[0059] On the basis of the above embodiment, the frame 10 includes a top plate 11 and a bottom plate 12 spaced apart in the vertical direction, the active group 20 and the driven group 30 are arranged between the top plate 11 and the bottom plate 12, and the bottom plate 12 is provided with a guide groove 121 along the vertical direction. In addition to the driving device 41 and the driving shaft 42, the cleaning mechanism 40 also includes a first limit block 43 and a second limit block 44. The driving device 41 is connected to the driven member 31 and is used to drive the driving shaft 42 to rotate. The cleaning member is arranged at the lower end of the driving shaft 42. The driving device 41 is arranged on the upper side of the bottom plate 12, and the cleaning member is arranged on the lower side of the bottom plate 12. The driving shaft 42 is passed through the guide groove 121. The first limit block 43 and the second limit block 44 are respectively arranged on both sides of the driving shaft 42 in the radial direction. The first limit block 43 is limited in cooperation with one inner end side of the guide groove 121, and the second limit block 44 is limited in cooperation with the other inner end side of the guide groove 121. In this embodiment, the guide groove 121 serves to limit the movement path of the cleaning member between the retracted position and the extended position. Furthermore, the guide groove 121's two ends in the longitudinal direction correspond to the first limit block 43 and the second limit block 44, so that the cleaning member is correspondingly limited in both the retracted and extended positions, preventing the cleaning member from retracting or extending beyond its travel. In particular, when the cleaning member is in the retracted position, even if the cleaning member collides with an obstacle, it will continue to move toward the retracted position under the elastic support of the elastic member 50. The guiding cooperation between the first limit block 43 and the guide groove also limits the retraction range of the cleaning member, preventing it from undergoing significant displacement, thereby ensuring the cleaning member's stability and cleaning range.

[0060] Optionally, a detection mechanism may be further provided on the lower side of the top plate 11 , and the detection mechanism cooperates with a detection portion provided on the upper side of the driven gear, so that the cleaning assembly 100 has a detection function for detecting whether the cleaning member has moved into position.

[0061] Please continue reading Figure 9 and Figure 10 The cleaning mechanism 40 further includes a cover plate 45, which is connected to the drive device 41 and sleeved around the outer periphery of the drive shaft 42. The cover plate 45 covers the lower side of the guide groove 121 and always covers the guide groove 121 during the movable stroke of the cleaning member. In this embodiment, the cover plate 45 covering the outer side of the guide groove 121 makes the cleaning assembly 100 more smooth and beautiful, and prevents dust from entering.

[0062] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
