Therefore, they should not be construed as limiting the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0057] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0058] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0059] See also Figures 1 to 13 As shown, according to an embodiment of this application, an automatic cleaning device is provided, including a housing 1 and a lateral cleaning assembly. The lateral cleaning assembly includes a connecting part 2 and a cleaning element 4. The cleaning element 4 is movably connected to the housing 1 through the connecting part 2, and the movement path includes a first position and a second position. The cleaning element 4 rotates and extends and retracts on the circumferential side of the housing 1 through the connecting part 2 to switch between the first position and the second position. When the cleaning element 4 is in the first position, it is at least partially offset in the extension and retraction direction compared to when it is in the second position.
[0060] By movably connecting the connecting part 2 to the housing 1 and enabling the cleaning element 4 to switch between at least partially offset first and second positions, different areas can be covered. This allows the cleaning element 4 to adaptively adjust its position according to cleaning needs, thereby meeting those needs and achieving a good cleaning effect. The cleaning element 4's rotation and extension along the circumferential side of the housing 1 via the connecting part 2 allows for smoother movement of the cleaning element 4, reduces the space occupied by the movement path, and minimizes the risk of jamming during movement.
[0061] Specifically, when the area to be cleaned is the baseboard, the position of the cleaning element 4 on the housing 1 can be adjusted according to the height of the baseboard to ensure that the cleaning element 4 is compatible with the position of the baseboard. During cleaning, the cleaning element 4 can be rotated and extended circumferentially on the housing 1 to fit snugly against the baseboard. This increases the distance between the automatic cleaning device 5 and the baseboard, preventing collisions between the housing 1 of the automatic cleaning device 5 and the baseboard, reducing movement restrictions on the automatic cleaning device 5, and also preventing structural interference between the cleaning element 4 and the housing 1 of the automatic cleaning device 5.
[0062] Here, the first position and the second position are relative to the housing 1 of the automatic cleaning device 5, not relative to the environment in which the automatic cleaning device 5 is located. For example, when the automatic cleaning device 5 is moving on the ground, since the first position and the second position are relative to the housing 1 of the automatic cleaning device 5, the first position and the second position remain unchanged.
[0063] Specifically, the first position and the second position can be the two endpoints of the movement path of the cleaning element 4. The first position is the extreme position when the cleaning element 4 moves toward the housing 1, and the second position is the extreme position when the cleaning element 4 moves away from the housing 1.
[0064] It is understandable that the first position and the second position can also be positions within the movement path of the cleaning element 4, rather than two endpoints.
[0065] In this context, the circumferential side of shell 1 refers to the horizontal outer side, including the front, back, left, and right sides. For example, if shell 1 has a disc-shaped structure, the circumferential side refers to the radial outer side of shell 1.
[0066] The cleaning element 4 extends or retracts circumferentially on the housing 1 via the connecting part 2. Extending means extending outward while rotating, and retracting means retracting towards the side where the housing 1 is located while rotating.
[0067] Specifically, the cleaning element 4 can be positioned on the left and / or right side of the automatic cleaning device 5. When the automatic cleaning device 5 moves linearly along the wall, the cleaning element 4 can contact the baseboard to achieve cleaning. In this embodiment, the cleaning element 4 is positioned on the right side of the automatic cleaning device 5. When cleaning a corner, the right side of the automatic cleaning device 5 is usually closer to the corner. Positioning the cleaning element 4 on the right side allows it to contact the baseboard.
[0068] In this design, the cleaning element 4, when in its first position, is at least partially offset from its second position in the direction of its extension and retraction. That is, viewed from the direction of extension and retraction, at least a portion of the cleaning element 4 in its first position does not overlap with its second position. Specifically, a vertical plane perpendicular to the direction of extension and retraction of the cleaning element 4 is selected as the projection plane. The projection of the cleaning element 4 in its first position onto this projection plane is defined as the first projection, and the projection of the cleaning element 4 in its second position onto this projection plane is defined as the second projection. The first projection and the second projection are at least partially non-overlapping, meaning they are at least partially offset. This design allows the cleaning element 4 to cover different areas, enabling it to adaptively adjust its position according to cleaning needs, thereby satisfying those needs.
[0069] After the cleaning element 4 moves to the first position and the second position, it can be locked in the first position and the second position to prevent the cleaning element 4 from accidentally extending or retracting.
[0070] Specifically, after the cleaning element 4 moves to the first position and the second position, the position can be locked by applying elastic force through the first elastic element 31 or by methods such as motor stall or motor self-locking.
[0071] More specifically, a first elastic element 31 can be provided to apply an elastic force to the connecting plate or the cleaning element 4, thereby holding the cleaning element 4 in the first and second positions through the elastic force. A motor can also be provided and connected to the connecting part 2, thereby driving the cleaning element 4 to move. After the cleaning element 4 moves to the first and second positions, the motor stalls or self-locks, thereby holding the cleaning element 4 in the first and second positions.
[0072] The connecting part 2 includes a first connector 21, which is rotatably connected to the housing 1. The first connector 21 can rotate outward toward the outside of the housing 1 or rotate inward toward the inside of the housing 1 and retract. The end of the first connector 21 outside the housing 1 is connected to the cleaning element 4.
[0073] The first connector 21 provides an installation position for the cleaning element 4. By rotatably connecting the first connector 21 to the housing 1 and allowing it to extend outward or retract inward, the adjustment process of the cleaning element 4 is simple and efficient, enabling the cleaning element 4 to better meet cleaning needs.
[0074] One end of the first connector 21 extends into the housing 1, and the other end extends out of the housing 1 and is fixedly connected to the cleaning element 4.
[0075] The first connector 21, located at one end inside the housing 1, can be connected to the drive component, thereby driving the first connector 21 to rotate and extend, which in turn drives the cleaning element 4 to rotate.
[0076] The housing 1 is provided with a threaded hole, and the first connecting piece 21 is threadedly connected to the threaded hole.
[0077] By setting threaded holes, the first connector 21 can be threadedly connected to the housing 1 through the threaded holes. The connection method is simple and reliable. By driving the first connector 21 to rotate, the first connector 21 can be driven to extend and retract synchronously. The driving method is direct and stable, and it can also achieve precise adjustment of the position of the cleaning element 4.
[0078] The threaded hole is opened horizontally on the outer peripheral wall of the housing 1, and the outer peripheral wall of the first connector 21 is provided with an external thread that matches the threaded hole. The first connector 21 passes through the threaded hole horizontally.
[0079] The threaded hole is located on the left or right side of the housing 1, allowing the cleaning element 4 to be positioned on either the left or right side of the housing 1. In this embodiment, the threaded hole is located on the right side of the housing 1.
[0080] The cleaning element 4 is eccentrically positioned on the first connector 21, allowing the cleaning element 4 to rotate eccentrically with the first connector 21. This enables the cleaning element 4 to cover a wider area around the first connector 21 and to adaptively adjust its position according to cleaning needs, thereby meeting the cleaning requirements.
[0081] The cleaning element 4 can be a regular shape, such as a square or an oval shape. The center of the cleaning element 4 can be the center point of the regular shape, that is, the center point of the cleaning element 4 is not located on the rotation axis of the first connector 21.
[0082] The cleaning element 4 is elongated, which makes the height of the cleaning element 4 different when it is in the first position and the second position.
[0083] Specifically, when the cleaning element 4 is an irregular elongated shape, the intersection of the rotation axis of the cleaning element 4 and the first connecting member 21 is closer to one end in the length direction, which is an eccentric setting.
[0084] The first connector 21 includes a rod 211 and a seat 212. The seat 212 is eccentrically mounted on the rod 211. The cleaning element 4 is mounted on the seat 212. The rod 211 is threadedly connected to the side wall of the housing 1.
[0085] By mounting the cleaning element 4 on the base 212, which is eccentrically mounted on the rod 211, an indirect connection is achieved between the cleaning element 4 and the rod 211. This ensures that the cleaning element 4 can move with the rod 211, and the eccentricity of the base 212 provides unique movement characteristics for the cleaning element 4, thereby increasing its coverage area. The rod 211 ensures a stable threaded connection between the connector and the threaded hole in the housing 1, guaranteeing the secure fixation of the first connector 21 to the housing 1. This prevents the cleaning element 4 from easily shaking or shifting due to external forces during operation, ensuring the normal operation of the cleaning equipment.
[0086] Among them, the rod body 211 is a threaded rod, that is, the rod body 211 is a cylindrical straight rod with threads on its outer peripheral wall, and thus it is threadedly connected to the threaded hole of the housing 1.
[0087] Specifically, the rod 211 is horizontally positioned and passes through a threaded hole on the left or right side wall of the housing 1. In this embodiment, the threaded hole is located on the right side wall of the housing 1, and the rod 211 passes horizontally through the threaded hole on the right side wall.
[0088] The base 212 is eccentrically positioned at one end of the rod 211 located outside the housing 1.
[0089] The rod 211 and the base 212 can be an integral structure, specifically, they can be molded as one piece, which ensures good stability and reliability.
[0090] The base 212 is provided with a mounting groove, which is adapted to the cleaning element 4, and the cleaning element 4 is placed in the mounting groove.
[0091] By setting the mounting slot, an installation position is provided for the cleaning element 4, making the mounting slot compatible with the cleaning element 4 and providing precise positioning for the cleaning element 4. This allows a tight connection between the cleaning element 4 and the base 212, enabling the cleaning element 4 to be accurately placed in the mounting slot. This prevents the cleaning element 4 from shifting or shaking due to external forces during equipment operation, ensuring the accuracy of the cleaning element 4's position during operation and thus ensuring the stability of the cleaning effect.
[0092] The base 212 is roughly plate-shaped and is vertically connected to the rod 211, meaning the base 212 is vertically positioned. The mounting groove is located on the outer wall of the base 212 away from the rod 211.
[0093] The depth of the mounting groove is less than the thickness of the cleaning element 4.
[0094] Specifically, in this embodiment, the cleaning element 4 is waist-shaped, the mounting groove is also waist-shaped, and its size is adapted to the cleaning element 4.
[0095] The cleaning element 4 extends vertically when it is in the first position and the second position, with the second position being at least partially higher or lower than the first position.
[0096] This allows the cleaning element 4 to cover different height ranges vertically. For different height sections of the baseboard, the cleaning element 4 can switch between a first position and a second position to achieve effective cleaning. For example, when the higher part of the baseboard needs cleaning, the cleaning element 4 can move to the second position. When the lower part of the baseboard needs cleaning, the cleaning element 4 can move to the first position, thus ensuring full coverage of the entire height range of the baseboard.
[0097] Specifically, in this embodiment, when the cleaning element 4 is in the second position, it is at least partially located on the side away from the housing 1 compared to when it is in the first position. That is, the cleaning element 4 is further away from the housing when it is in the second position than when it is in the first position. At least a portion of the cleaning element 4 in the first position is higher than the cleaning element 4 in the second position, and the cleaning element 4 is higher when it is in the second position than when it is in the first position.
[0098] like Figure 1As shown, when the automatic cleaning device 5 is in the first state, the cleaning element 4 is in a lower first position, which allows for cleaning of the lower portion of the baseboard. Figure 2 As shown, when the automatic cleaning device 5 is in the second state, the cleaning element 4 is in a position between the first and second positions. The cleaning element 4 can pass through this intermediate position or stop at this intermediate position by means of motor self-locking, thereby cleaning the middle part of the baseboard. Figure 3 As shown, when the automatic cleaning device 5 is in the third state, the cleaning element 4 is in the higher second position, which can clean the higher part of the baseboard.
[0099] As the cleaning element 4 moves from the first position to the second position, the distance between the cleaning element 4 and the housing 1 gradually increases. The outer side of the cleaning element 4 in the second position is further away from the housing 1 than the outer side of the cleaning element 4 in the first position.
[0100] Among them, the cleaning element 4 is elongated, and when the cleaning element 4 is in the first position and the second position, the length direction of the cleaning element 4 is vertical.
[0101] Specifically, the top of the cleaning element 4 in the second position is higher than the top of the cleaning element 4 in the first position. The bottom of the cleaning element 4 in the first position is lower than the bottom of the cleaning element 4 in the second position.
[0102] The second position is at least partially higher than the highest point of the housing 1 where the cleaning element 4 is located, so that the cleaning element 4 can clean the baseboard that is higher than the housing 1.
[0103] Specifically, when the cleaning element 4 is in the second position, the upper part of the second position exceeds the height of the housing 1 at that location.
[0104] Here, the location of cleaning element 4 refers to the portion of housing 1 adjacent to cleaning element 4. For example... Figures 4 to 7 Part of the housing 1 shown.
[0105] Specifically, the location of the cleaning element 4 can refer to the portion of the housing 1 that overlaps with the rotation range of the cleaning element 4.
[0106] Specifically, the cleaning element 4 can rotate 180° from the first position to reach the second position. Alternatively, it can be set to rotate 540° or a similar degree to reach the second position, with the cleaning element 4 being 180° off from its first and second positions.
[0107] The automatic cleaning device 5 includes a reset part 3, which is connected to a connecting part 2. When the cleaning element 4 is unlocked from the second position, the connecting part 2 is rotated along the first circumferential direction so that the cleaning element 4 moves from the second position away from the housing 1 to the first position close to the housing 1.
[0108] By connecting the reset part 3 to the connecting part 2, when the cleaning element 4 is unlocked from the second position, the reset part 3 can drive the connecting part 2 to rotate along the first circumferential direction, thereby automatically moving the cleaning element 4 from the second position away from the housing 1 to the first position close to the housing 1, achieving automatic reset and improving the ease of use of the cleaning equipment. When the cleaning element 4 collides with an external object, the cleaning element 4 unlocks from the second position, causing the reset part 3 to drive the cleaning element 4 back to the first position, thus preventing damage caused by excessive collision between the cleaning element 4 and external objects.
[0109] The cleaning element 4 can be unlocked from the second position either actively or passively.
[0110] Specifically, after the automatic cleaning device 5 detects an obstacle in front, it actively unlocks. The reset unit 3 can be a motor, which drives the cleaning element 4 to rotate along the first circumference to a first position, thereby allowing the cleaning element 4 to avoid the obstacle and prevent a collision. In this scenario, the cleaning element 4 can be locked in a second position by the motor's self-locking or stall mechanism.
[0111] Specifically, after the cleaning element 4 collides with an obstacle, a force is generated. If this force exceeds a preset threshold, the cleaning element 4 is passively unlocked from the second position. In this scenario, the cleaning element 4 can be locked in the second position by the self-locking mechanism of the motor. When the force generated after the collision exceeds the preset self-locking threshold, the motor unlocks, meaning the cleaning element 4 unlocks from the second position. In this scenario, the cleaning element 4 can also be locked in the second position by, for example, the elastic force of the first elastic element 31. When the force generated after the collision exceeds the locking elastic force, the cleaning element 4 unlocks from the second position.
[0112] The reset part 3 includes a first elastic member 31, which includes a fixed end 311 and a connecting end 312. The fixed end 311 is fixed to the housing 1, and the connecting end 312 is connected to the connecting part 2.
[0113] By incorporating the first elastic element 31, a stable and reliable rotational power can be provided to the connecting part 2, ensuring that the cleaning element 4 smoothly moves from the second position to the first position, thus achieving an automatic reset function. Compared to complex mechanical reset structures such as motors, the first elastic element 31 has a simpler and more compact structure, occupies less space, and can achieve the reset function within a limited equipment space, which is beneficial for the miniaturization design of cleaning equipment. At the same time, the first elastic element 31 has a lower cost, which helps reduce the production cost of the equipment.
[0114] The first elastic element 31 can be a tension spring, one end of which is a fixed end 311 and is fixedly connected to the housing 1. The other end of the tension spring is a connecting end 312 and is connected to the connecting part 2.
[0115] Specifically, a connecting shaft is provided on the inner wall of the housing 1, and a hook is provided on the fixed end 311 of the tension spring, which is detachably connected to the connecting shaft through the hook.
[0116] When the cleaning element 4 is in the second position, the tension spring is in a stretched state. After the cleaning element 4 is unlocked from the second position, the tension spring pulls the connecting part 2 to rotate through its own elastic force, thereby driving the cleaning element 4 to return to the first position.
[0117] In one feasible embodiment, such as Figures 4 to 7 As shown, a connecting structure is eccentrically provided on the connecting part 2, and the connecting end 312 of the first elastic member 31 is connected to the connecting structure.
[0118] By setting the connecting structure eccentrically on the connecting part 2, when the first elastic element 31 pulls the connecting structure, a suitable torque is generated due to the eccentricity, which can more effectively drive the connecting part 2 to rotate.
[0119] The connecting structure is eccentrically positioned on the connecting part 2, meaning that the connecting structure is located outside the rotation axis of the connecting part 2.
[0120] Specifically, the connecting structure is eccentrically positioned relative to the end face of the rod 211 of the first connecting member 21. The connecting structure can be directly eccentrically positioned on the end face of the rod 211 of the first connecting member 21, such that the connecting end 312 of the first elastic member 31 connects to the rod 211 of the first connecting member 21, and the connection point is located at an eccentric position within the circle formed by the connecting ends 312. Other connecting components can also be connected to the rod 211 of the first connecting member 21, with the connecting structure eccentrically positioned on these connecting components.
[0121] The connection structure is a connecting post 221, which extends axially along the connecting part 2, and the connecting end 312 of the first elastic member 31 is detachably connected to the connecting post 221.
[0122] By setting the connecting post 221, a stable connection point is provided for the first elastic element 31, which can better withstand the tensile force applied by the first elastic element 31, ensuring the stability of the connection and thus ensuring that the reset action can be carried out smoothly. By making the connecting end 312 of the first elastic element 31 detachably connected to the connecting post 221, the installation and disassembly process is simple and convenient, facilitating replacement and maintenance.
[0123] The connecting post 221 extends axially along the connecting portion 2 and protrudes from the end face of the connecting portion 2.
[0124] The connecting end 312 of the tension spring is provided with a hook and is detachably connected to the connecting post 221 via the hook.
[0125] The end of the connecting post 221 is provided with an anti-detachment structure. The anti-detachment structure is larger than the diameter of the connecting post 221, so as to stop the hook and prevent the hook from coming off the connecting post 221.
[0126] Of course, the connection structure can also be a connecting lug, a connecting hole, etc., and the connecting end 312 of the tension spring can be detachably connected to the connecting lug or the connecting hole.
[0127] In the trajectory of the connecting structure moving with the connecting part 2, the point farthest from the fixed end 311 of the first elastic member 31 is the elastic force reversal point. When the connecting structure is on the first circumferential side of the elastic force reversal point, the first elastic member 31 drives the connecting structure to rotate along the first circumferential direction. The opposite direction of the first circumferential direction is the second circumferential direction. When the connecting structure is on the second circumferential side of the elastic force reversal point, the first elastic member 31 drives the connecting structure to rotate along the second circumferential direction.
[0128] By causing the first elastic element 31 to rotate the connecting structure along the first circumferential direction, the cleaning element 4 can be reset to the first position. By causing the first elastic element 31 to rotate the connecting structure along the second circumferential direction, the cleaning element 4 can be moved to the second position. The overall structure is simple, the motion stability is strong, and the production cost is low.
[0129] The first elastic element 31 is a tension spring. The fixed end 311 of the first elastic element 31 is located on the side away from the connecting part 2. The connecting end 312 of the first elastic element 31 extends in a straight line toward the connecting part 2 and is connected to the connecting structure. The connecting structure can be the connecting post 221 mentioned above.
[0130] The connecting structure moves along an arc-shaped trajectory with the connecting part 2. The opening of the arc generally faces the fixed end 311 of the first elastic element 31, and the middle section of the arc arches away from the fixed end 311. During the entire movement, the first elastic element 31 reaches its maximum stretch length when the connecting end 312 moves with the connecting structure to the elastic force reversal point. As it moves from the elastic force reversal point along the first and second circumferential directions, the elastic potential energy of the first elastic element 31 is released, and the stretch length gradually shortens, causing the connecting structure and the connecting part 2 to rotate.
[0131] The housing 1 is provided with a first limiting structure, and the connecting part 2 is provided with a second limiting structure. The first limiting structure and the second limiting structure slide together along the circumference of the connecting part 2.
[0132] The sliding engagement of the first and second limiting structures provides precise motion guidance for the rotation of the connecting part 2, ensuring that the rotational and telescopic movements of the cleaning element 4 through the connecting part 2 follow a predetermined trajectory, thereby guaranteeing the normal operation and cleaning effect of the cleaning equipment. Simultaneously, the first and second limiting structures make the movement of the connecting part 2 more stable. By restricting the direction of movement of the connecting part 2, problems such as shaking and displacement of the cleaning element 4 caused by unstable movement of the connecting part 2 are reduced, improving the accuracy and reliability of the cleaning element 4 switching between different positions.
[0133] The sliding fit structure formed by the first limiting structure and the second limiting structure can be a ring track and roller, an arc-shaped guide post and guide hole, a slide groove 11 and a slider 222, etc.
[0134] In this embodiment, the first limiting structure is a slide groove 11, and the second limiting structure is a slider 222. The slide groove 11 extends in an arc shape along the first and second circumferential directions, and the slider 222 is slidably disposed in the slide groove 11.
[0135] By setting the first and second limiting structures as an arc-shaped groove 11 and a slider 222, respectively, where the arc-shaped groove 11 matches the circumferential movement trajectory of the connecting part 2, the slider 222 can slide smoothly within the groove 11. The connecting part 2 achieves circumferential movement through the sliding of the slider 222 within the groove 11, providing stable motion guidance for the circumferential movement of the connecting part 2. This ensures smoother movement of the connecting part 2, thereby improving the accuracy and stability of the cleaning element 4 switching between different positions.
[0136] The slide groove 11 extends in an arc shape along the first and second circumferential directions, so that the slide groove 11 matches the rotation trajectory of the connecting part 2.
[0137] The slider 222 extends along the axial direction of the connecting part 2, and the groove depth direction of the groove 11 is also along the axial direction of the connecting part 2. The slider 222 is inserted into the groove 11 along the axial direction of the connecting part 2, and the slider 222 rotates synchronously with the connecting part 2 while sliding along the extending direction of the groove 11.
[0138] In this embodiment, one end of the slide groove 11 along the first circumferential direction is defined as the reset end. As one implementation, when the cleaning element 4 is in the first position, the slider 222 can abut against the reset end, thereby limiting the connection portion 2 in the first circumferential direction, that is, limiting the cleaning element 4 in the first circumferential direction, preventing the cleaning element 4 from continuing to move along the first circumferential direction after reaching the first position. As another implementation, the slide groove 11 can also continue to extend along the first circumferential direction, so that when the cleaning element 4 is in the first position, the slider 222 does not contact the reset end, avoiding collisions that could damage the slider 222 or generate noise.
[0139] One end of the slide groove 11 along the second circumferential direction is the locking end. When the cleaning element 4 is in the second position, the locking end abuts against the slider 222 to limit the slider 222 in the second circumferential direction. At the same time, the connecting structure is located on the second circumferential side of the spring reversal point so that the slider 222 is pressed against the locking end to lock the cleaning element 4 in the second position.
[0140] The first elastic element 31 can apply elastic force to the connecting structure to press the slider 222 onto the locking end, thereby locking the cleaning element 4 in the second position. When the cleaning element 4 is cleaning in the second position, it will not move accidentally due to equipment vibration or other external forces, ensuring the stability and reliability of the cleaning operation. Moreover, the reset and locking can be completed by the first elastic element 31 alone, which is stable, reliable, and has a low manufacturing cost.
[0141] When the cleaning element 4 collides with an external obstacle, the slider 222, under the action of external force, overcomes the elastic force of the first elastic member 31 and moves along the first circumferential direction toward the elastic force reversal point. If the external force is less than the elastic force of the first elastic member 31 at the elastic force reversal point, the first elastic member 31 pulls the connecting part 2 to rotate along the second circumferential direction, and the slider 222 returns to the locking end. If the external force is greater than the elastic force of the first elastic member 31 at the elastic force reversal point, the slider 222 passes the elastic force reversal point along the first circumferential direction. After the elastic force of the first elastic member 31 reverses, it drives the slider 222 to slide along the first circumferential direction, that is, to slide toward the reset end, achieving automatic reset. This prevents excessive external force from colliding the cleaning element 4 with the obstacle, thus avoiding damage to the cleaning element 4 or the connecting part 2, and providing protection.
[0142] The first elastic element 31 presses the slider 222 onto the locking end, which in turn provides support for the cleaning element 4 when cleaning the baseboard, counteracting the friction between the cleaning element 4 and the baseboard, so that the cleaning element 4 can be pressed and slide along the baseboard, thereby achieving cleaning.
[0143] The connecting part 2 includes a second connecting member 22. When the connecting part 2 includes a first connecting member 21, the second connecting member is connected to the first connecting member 21 and rotates synchronously. The connecting structure is provided on the second connecting member 22.
[0144] By setting the second connector 22 to cooperate with the first connector 21, it is easy to assemble the connecting part 2 onto the housing 1 and to provide a setting position for the connecting structure.
[0145] When the connecting part 2 is assembled onto the housing 1, most of the first connecting member 21 is outside the housing 1, and most of the second connecting member 22 is inside the housing 1.
[0146] Specifically, the rod 211 of the first connector 21 extends into the housing 1 after passing through the threaded hole, while the seat 212 is located outside the housing 1. The second connector 22 is inserted into the rod 211 along the extension direction of the first rod 211.
[0147] The second connecting member 22 includes a cam, and the connecting structure is disposed on the cam's protrusion. That is, the connecting end 312 of the first elastic member 31 is connected to the cam's protrusion through the connecting post 221, which increases the rotational torque.
[0148] The cam is roughly disc-shaped, and is set perpendicular to the rotation axis of the connecting part 2. The cam's convex part protrudes outward along the radial direction of the rod 211.
[0149] The second limiting structure is formed on the second connector 22, so that when the second connector 22 rotates synchronously with the first connector 21, it can drive the second limiting structure to rotate, thereby causing the second limiting structure to slide relative to the first limiting structure, thus playing a guiding and limiting role.
[0150] The second limiting structure is a slider 222, which is perpendicular to the disc shape formed by the cam and protrudes toward the first limiting structure, and is then inserted into the groove 11 formed by the first limiting structure.
[0151] The second connector 22 includes a plug post 223, and the first connector 21 includes a plug groove 213. The plug post 223 is inserted into the plug groove 213 along the axial direction of the connector 2. The outer peripheral wall of the plug post 223 is in concave-convex fit with the groove wall of the plug groove 213 so that the second connector rotates synchronously with the first connector 21.
[0152] By setting the plug-in post 223 and the plug-in groove 213, the first connector 21 and the second connector 22 can be connected easily, improving assembly efficiency. By making the outer peripheral wall of the plug-in post 223 and the groove wall of the plug-in groove 213 fit together, the second connector can drive the first connector 21 to rotate synchronously, thereby driving the cleaning element 4 to rotate, and transmitting torque stably and reliably.
[0153] The insertion post 223 is set perpendicular to the cam.
[0154] The insertion post 223 is eccentrically positioned with respect to the cam, which includes a circular wheel portion and a convex portion. Specifically, the contact point between the insertion post 223 and the cam is located on the side of the wheel portion away from the convex portion, further increasing the torque.
[0155] The insertion post 223 and the cam are an integral structure and can be molded as a single piece.
[0156] The outer peripheral wall of the plug-in post 223 is provided with multiple protruding ridges, which extend axially and are evenly arranged circumferentially. The groove wall of the plug-in slot 213 is provided with multiple grooves corresponding to the protruding ridges, which extend axially and are evenly arranged circumferentially. The shape and size of the cam are adapted to the grooves, and the cam is inserted into the grooves one by one, thereby causing the second connector and the first connector 21 to rotate synchronously in the circumferential direction.
[0157] A second elastic element is sleeved on the plug post 223. One end of the second elastic element abuts against the housing 1, and the other end abuts against the second connector 22, so as to apply an elastic force to the second connector 22 along the axial direction of the plug post 223 and toward the housing 1.
[0158] By setting a second elastic element, the second connector 22 tends to move closer to the housing 1, which makes the first connector 21 connected to the second connector 22 fit more tightly to the housing 1, reducing shaking. It also allows the threads on the rod 211 of the first connector 21 to press against the threads of the threaded hole in the housing 1, keeping the threads engaged, so that the first connector 21 can move stably into the housing 1 when the cleaning element 4 moves toward the first position.
[0159] The second elastic element is a compression spring, which is sleeved on the plug post 223.
[0160] Specifically, an abutment platform is provided inside the threaded hole. The abutment platform protrudes radially. One end of the second elastic member abuts against the abutment platform, and the other end abuts against the cam. The second elastic member is in a compressed state, thereby applying an elastic force to the boss along the axial direction of the insertion post 223 and toward the housing 1.
[0161] In this process, after the plug-in post 223 is plugged into the plug-in groove 213, glue is applied to fix the plug-in post 223 and the plug-in groove 213 in a secure manner, so as to prevent the elastic force of the compression spring from causing the plug-in post 223 to come out of the plug-in groove 213.
[0162] In another feasible embodiment, such as Figure 14 As shown, the reset part 3 includes a connecting rope 32, and the connecting end 312 of the first elastic member 31 is connected to the connecting rope 32. The connecting rope 32 is wound around the connecting part 2 in the first circumferential direction.
[0163] By setting the connecting rope 32 and the first elastic element 31, it is also possible to drive the connecting part 2 to rotate in the first circumferential direction, thereby driving the cleaning element 4 to reset to the first position.
[0164] The second connector 22 is provided with a groove, which extends circumferentially, and the connecting rope 32 is wound inside the groove.
[0165] The groove is located on the cam of the second connector 22 and extends circumferentially along the cam.
[0166] When it is necessary to clean the baseboard, the cleaning element 4 can be manually moved to the second position.
[0167] The automatic cleaning device 5 includes a drive unit connected to the connecting unit 2, which drives the cleaning element 4 from a first position close to the housing 1 to a second position away from the housing 1.
[0168] When the baseboard needs cleaning, the cleaning element 4 can be automatically rotated to the second position by the drive unit without manual intervention, which greatly improves the automation level and ease of use of the cleaning equipment.
[0169] The drive unit includes a drive motor, which is housed inside the housing 1 and connected to the connecting part 2.
[0170] Specifically, the motor can be connected to the second connecting member 22, thereby driving the second connecting member 22 to rotate in the second circumferential direction, and then driving the cleaning element 4 to rotate through the first connecting member 21. When the connection structure is on the first circumferential side of the elastic reversal point, the motor overcomes the elastic force of the first elastic member 31 and drives the second connecting member 22 to rotate in the second circumferential direction. After passing the elastic reversal point, the first elastic member 31 and the motor jointly drive the second connecting member 22 to rotate in the second circumferential direction until the slider 222 abuts against the locking end of the slide groove 11.
[0171] The motor can also drive the cleaning element 4 to move from the second position to the first position.
[0172] Specifically, when the connecting structure is on the second circumferential side of the elastic reversal point, the motor overcomes the elastic force of the first elastic element 31 and drives the second connecting element 22 to rotate along the first circumferential direction. After passing the elastic reversal point, the motor can be powered off, and the first elastic element 31 drives the second connecting element 22 to rotate along the first circumferential direction.
[0173] The housing 1 is provided with a receiving groove, and the reset part 3 and the drive part are disposed in the receiving groove.
[0174] While providing a mounting position for the reset unit 3 and the drive unit, it also provides protection for the reset unit 3 and the drive unit.
[0175] In a second aspect of this embodiment, an automatic cleaning system is provided, including a base station and an automatic cleaning device 5 as described above, the automatic cleaning device 5 being adapted to dock on the base station.
[0176] Among them, the automatic cleaning device 5 can be a robot vacuum cleaner.
[0177] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
