DETAILED DESCRIPTION

[0055] In order to make the purpose, technical scheme and advantages of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0056] The embodiments of the utility model will be described below in combination with Figures 1 to 10 .

[0057] The utility model discloses a kind of cleaning devices, including cleaning head and cleaning rod 1, cleaning head includes cleaning part 21;Cleaning part 21 is used to clean the surface to be cleaned;The surface to be cleaned can include ground, glass surface, desktop etc. any surface;The surface to be cleaned can be surface smooth or rough plane, can also be surface smooth or rough curved surface etc. any surface.

[0058] The application further discloses some embodiments, and the cleaning head further includes a limiting structure 22, and the limiting structure 22 is arranged on the cleaning rod 1. The limiting structure 22 can be fixedly arranged on the cleaning rod 1. The limiting structure 22 can also be movably connected with the cleaning rod 1, and can be movably relative to the cleaning rod 1.

[0059] The application further discloses some embodiments, the cleaning part 21 has a first position and a second position on the cleaning rod 1, when the cleaning part 21 moves to the first position on the cleaning rod 1, the limiting structure 22 can limit the rotation of the cleaning part 21 relative to the cleaning rod 1, when the cleaning part 21 moves to the second position on the cleaning rod 1, the limiting structure 22 removes the rotation limitation of the cleaning part 21 relative to the cleaning rod 1. When the cleaning part 21 moves to the first position relative to the cleaning rod 1, the limiting structure 22 limits the rotation of the cleaning part 21 relative to the cleaning rod 1, so that the cleaning part 21 can work stably under certain conditions, and the cleaning head can resist external interference and maintain a stable state, and the cleaning head cannot rotate easily due to accidental force, thereby affecting the accuracy and cleaning effect. When the cleaning part 21 moves to the second position, the limiting structure 22 removes the rotation limitation of the cleaning part 21 relative to the cleaning rod 1, so that the cleaning head can rotate freely according to the shape of the cleaning object, thereby greatly improving the flexibility of the cleaning device. And the relative movement of the cleaning part 21 and the cleaning rod 1 realizes the fixing of the cleaning part 21 and the rotation of the cleaning head, so that the operation is simple, the visualization degree is high, and the user can use conveniently. In the embodiment, the cleaning part 21 can be a cleaning head such as a cloth head, a scraping head with a scraping head, a brush head and the like.

[0060] The application further discloses some embodiments, when the cleaning part 21 is in the second position, the limiting structure 22 and the cleaning part 21 can rotate synchronously relative to the cleaning rod 1, so that the cleaning head can rotate relative to the cleaning rod 1; when the cleaning part 21 is in the first position, the limiting structure 22 and the cleaning part 21 limit the rotation of each other relative to the cleaning rod 1, so that the cleaning head and the cleaning rod 1 remain relatively static.

[0061] Further, when the cleaning part 21 is in the second position, the rotation centers of the cleaning part 21 and the limiting structure 22 are coaxial, so that the cleaning part 21 and the limiting structure 22 can rotate synchronously, and the collision or friction between the cleaning part 21 and the limiting structure 22 can be prevented, thereby improving the use stability and service life of the product.

[0062] In some embodiments, the limiting structure 22 comprises two oppositely arranged limiting parts 221, when the cleaning part 21 moves to the first position on the cleaning rod 1, the two limiting parts limit the rotation of the cleaning part 21 relative to the cleaning rod 1 respectively; the two oppositely arranged limiting parts 221 can limit the rotation of the cleaning part 21 relative to the cleaning rod 1 in the clockwise and counterclockwise directions simultaneously, so that the relative rotation between the cleaning part 21 and the cleaning rod 1 can be prevented effectively.

[0063] Further, the limiting part 221 can comprise two opposite hooks, the two opposite hooks are arranged on the opposite sides of the cleaning rod 1, the two hooks can be clamped with the edges of the cleaning part 21, so as to limit the rotation of the cleaning part 21 relative to the cleaning rod 1, when the cleaning part 21 moves relative to the cleaning rod 1, the hooks can be deformed and separated from the limiting of the hooks, so that the rotation of the cleaning part 21 relative to the cleaning rod 1 can be limited.

[0064] Further, at least one of the two opposite limiting portions 221 can be a plane shaped to be opposite to the side surface of the cleaning portion 21 in the rotation direction of the cleaning rod 1 to limit the rotation of the cleaning portion 21 relative to the rod body 11. For example, one of the two limiting portions 221 is a plane opposite to the side surface of the cleaning portion 21, and the other is a clamping hook or other limiting structure 22 capable of clamping the cleaning portion 21. Alternatively, both of the two limiting portions 221 are planes shaped to be opposite to the side surfaces of the cleaning portion 21 in the rotation direction of the cleaning rod 1, and the rotation of the cleaning portion 21 is limited by the two planes. The limiting effect is good, and the service life is long.

[0065] In some embodiments, a limiting protrusion is arranged on the cleaning portion 21, and at least one limiting portion 221 is shaped to be a protruding portion opposite to the side surface of the limiting protrusion in the rotation direction of the cleaning rod 1 to limit the rotation of the cleaning portion 21 relative to the cleaning rod 1. The limiting protrusion and the protruding portion are matched to realize rotation limiting, which is simple to manufacture, low in cost, and good in limiting effect.

[0066] Further, the protruding portion can be a baffle matched with the limiting protrusion to limit the rotation of the cleaning portion 21 relative to the cleaning rod 1. The baffle can be arranged as a strip-shaped baffle to further improve the reliability of the product.

[0067] The application also discloses some embodiments. The cleaning portion 21 comprises a clamping structure. The clamping structure has a clamping state and an open state. When the clamping structure switches from the open state to the clamping state, the clamping structure can gradually clamp the wiping member. When the clamping structure switches from the clamping state to the open state, the clamping structure can gradually release the wiping member. The clamping structure is used to act on the cleaning portion 21, which facilitates the replacement of the wiping member, is more convenient to use, and is more flexible in application scenarios.

[0068] The application also discloses some embodiments. The limiting structure 22 can limit the clamping structure to be in the clamping state. The relative movement between the clamping structure and the limiting structure 22 can enable the clamping structure to be limited by the limiting structure 22 or to be released from the limiting of the limiting structure 22, so as to switch the clamping structure between the clamping state and the open state. The limiting structure 22 limits the clamping structure to be in the clamping state, which provides a reliable fixing mode for the wiping member. The relative movement between the clamping structure and the limiting structure 22 can enable the clamping structure to be limited and released, so as to switch the clamping state and the open state, which greatly facilitates the replacement operation of the wiping member.

[0069] Further, the clamping structure comprises two clamping members capable of moving towards or away from each other, so that the clamping structure is switchable between the clamping state and the open state. When the clamping structure is in the clamping state, the clamping structure can not clamp the wiping member and has the wiping effect.

When the clamping structure clamps the wiping member, the cleaning part 21 is relatively stationary with respect to the cleaning rod 1, which facilitates clamping the wiping member. After clamping is completed, the cleaning part 21 can rotate with respect to the cleaning rod 1, which can be applied to different wiping scenarios, is more flexible to use, and has a richer application scenario.

[0071] In some embodiments, the limiting structure 22 comprises two folding heads 222 located on both sides of the two clamping members; the two folding heads 222 are used to clamp and limit the clamping structure, so that the clamping structure is in the clamping state. When the cleaning part 21 moves to the first position on the rod body 11, the two clamping members move away from each other, so that the clamping structure is in the open state; when the cleaning part 21 moves to the second position on the rod body 11, the two clamping members enter between the two folding heads 222, so that the two clamping members move towards each other, and the clamping structure is in the clamping state. The two clamping members move towards each other between the two folding heads 222, which is more stable and can prevent the clamping members from opening due to misoperation.

[0072] In some embodiments, the limiting structure 22 comprises a limiting shell extending circumferentially around the cleaning part 21 when the cleaning part 21 moves to the second position on the cleaning rod 1, and the two folding heads 222 are respectively inner wall surfaces of the limiting structure 22 located on both sides of the two clamping members. The two folding heads 222 are formed by the inner walls of the limiting shell, which is convenient to manufacture and install.

[0073] In some embodiments, the limiting structure 22 comprises two opposite limiting parts 221, and the limiting part 221 is a wall surface of the limiting shell adjacent to the two folding heads 222 respectively. The limiting structure 22 can limit the rotation of the cleaning part 21 with respect to the cleaning rod 1 when the cleaning part 21 is in the first position, and can clamp and limit the clamping structure when the cleaning part 21 is in the second position. The structure is simple, the cost is low, the limiting effect is good, and the use stability of the product is effectively ensured. The limiting shell is used for clamping and limiting, which can effectively prevent the clamping and limiting from being invalid due to accidental touch, so that the clamping structure is opened.

The concave-convex cooperation is simple in structure, convenient to manufacture and good in limiting effect.

[0075] In some embodiments, the guide groove extends in the axial direction of the cleaning rod 1 and can guide the cleaning part 21 to move in the axial direction of the cleaning rod.

[0076] The application further discloses some embodiments in which a tension member is further arranged on the cleaning part 21, the tension member can drive the two clamping members to move away from each other when the cleaning part 21 moves from the first position to the second position on the rod body 11, and the clamping members can be opened to facilitate the gripping of the wiping member.

[0077] Further, the tension member comprises an elastic member. The elastic member can be an elastic block or a rubber block.

[0078] The application further discloses some embodiments in which a movable driving part 3 is arranged on the cleaning rod 1, the driving part 3 can move in the axial direction of the cleaning rod 1, and the driving part 3 is connected with the cleaning part 21. In the application, the axial direction of the cleaning rod 1 refers to the length direction of the cleaning rod 1, but the movement of the driving part 3 on the cleaning rod 1 can be linear or curved, as long as the terminal point and the starting point are different positions in the axial direction of the cleaning rod 1.

The fixed sleeve 12 is provided with the axial extension 121, and the axial extension 121 is movably arranged in the through hole 312 of the closed end of the sleeve 31, which provides accurate guidance for the movement of the sleeve 31 on the fixed sleeve 12. When the user operates the sleeve 31 to move axially along the fixed sleeve 12, the axial extension 121 slides in the through hole 312, so that the movement track of the sleeve 31 is strictly limited in the axial direction, avoiding the sleeve 31 from deviating or shaking, thereby ensuring the accuracy and stability of the operation. At this time, the limiting structure 22 is connected with the axial extension 121 through the second rotating structure, and the second rotating structure comprises a first shaft and a second shaft arranged on the limiting structure.

[0091] In some embodiments, the axial extension 121 comprises a first axial extension plate and a second axial extension plate; the closed end is provided with a first through hole and a second through hole corresponding to the first axial extension plate and the second axial extension plate; the first axial extension plate and the second axial extension plate are respectively provided with a first hole and a second hole; the limiting structure 22 is provided with a first shaft and a second shaft, and the first shaft and the second shaft are rotatably arranged in the first hole and the second hole, so that the limiting structure 22 is rotatably arranged on the axial extension 121. The first shaft and the second shaft cooperate with the corresponding holes to not only realize the rotating function, but also to a certain extent, position and limit the rotation of the limiting structure 22. Moreover, the arrangement of the first shaft and the second shaft forms a double-shaft supporting structure, which can effectively disperse the stress during the rotation of the limiting structure 22 and the cleaning head is subjected to external force (such as friction force during wiping, reaction force generated when the cleaning head contacts the cleaning surface, etc.). Compared with the single-shaft rotating structure, the double-shaft structure can more evenly distribute the force on the limiting structure 22, the axial extension 121 and other components connected thereto, avoiding the situation that stress is concentrated in a certain place and causing damage to the components.

[0092] Further, the closed end is also provided with an axial extension 311, and the axial extension 311 is connected with the clamping structure; the axial extension 311 is arranged between the first axial extension plate and the second axial extension plate.

[0093] The application also discloses some embodiments, and the cleaning rod 1 is also provided with a locking structure 4; the locking structure 4 is used for locking or unlocking the driving part 3. By locking or unlocking the driving part 3 through the locking structure 4, accidental touching can be prevented, and the stable operation of the driving part 3 can be effectively ensured.

[0094] The application also discloses some embodiments, the locking structure 4 comprises a pressing piece, the pressing piece is pressingly arranged on the cleaning rod 1; the driving part 3 is provided with a locking hole 33; the pressing piece can extend into the locking hole 33 to lock the driving part 3; the pressing piece is pressed to make the pressing piece separate from the locking hole 33 to unlock the driving part 3. By using the pressing piece as the locking structure 4, the operation is simple, the use is convenient, the locking effect is good, and the unlocking is convenient.

[0095] In some embodiments, the pressing piece comprises a spring buckle, and the spring buckle is arranged on the cleaning rod 1 and can be elastically pressed on the cleaning rod 1.

[0096] In some embodiments, the pressing piece comprises a pressing hole formed on the cleaning rod 1, and the pressing piece moves in the pressing hole to extend out of or retract into the cleaning rod 1; when the pressing piece extends out of the cleaning rod 1, the pressing piece can extend into the locking hole 33 to lock the driving part 3; the pressing piece is pressed to make the pressing piece separate from the locking hole 33 and retract into the cleaning rod 1 to unlock the driving part 3.

[0097] The application also discloses some embodiments, the clamping structure comprises a movable piece 211 and a fixed piece 212, and the movable piece 211 and the fixed piece 212 form the two clamping pieces which can move close to or away from each other. The movable piece 211 comprises a flexible piece 2111, and the flexible piece 2111 is used for clamping or releasing the wiping piece; the cleaning head is arranged on the cleaning rod 1; the driving part 3 movably arranged on the cleaning rod 1; the driving part 3 is connected with the clamping structure; when the driving part 3 moves in the axial direction of the cleaning rod 1, one end of the movable piece 211 can move away from or close to the fixed piece 212 to make the clamping structure switch between the clamping state and the open state. In the application, the driving part 3 moves in the axial direction of the cleaning rod 1 to drive one end of the movable piece 211 to move away from or close to the fixed piece 212 to switch the state of the clamping structure, so that the operation is simple and convenient to replace, and the clamping state reliability of the clamping structure can be improved; and in the application, the clamping structure comprises the movable piece 211, the movable piece 211 comprises the flexible piece 2111, and the flexible piece 2111 is used for clamping and releasing the wiping piece, that is, the flexible piece 2111 is used for grabbing when the wiping piece is installed, so that the flexible piece 2111 cannot cause abrasion on the grabbing surface.

[0098] When the movable piece 211 is used to grab the wiping piece, the wiping piece can be laid on a surface to be cleaned or any surface, then the fixed piece is pressed on the wiping piece, and the movable piece 211 is driven to move in the direction close to the fixed piece 212, at this time, the movable piece 211 is attached to the laid wiping piece, and the wiping piece can be rolled up and clamped between the movable piece 211 and the fixed piece 212 in the movement process, and when the movable piece 211 moves to the clamping position, the fixed piece 212 and the movable piece 211 clamp the wiping piece between them.

[0099] Further, the flexible member 2111 can be made of rubber material, or other flexible material such as soft metal, soft plastic, etc. The wiping member can be a soft and foldable wiping member such as wiping cloth, wiping cotton, wiping gauze, etc. The fixing member 212 can be made of flexible material or rigid material. The flexible member 2111 in the movable member 211 plays a key role in clamping and releasing the wiping member; in the present application, the flexible member 2111 clamps or releases the wiping member, and places the wiping member on the surface to be cleaned, and the flexible member 2111 moves on the surface to be cleaned and the wiping member to clamp the wiping member; in this process, the flexible member 2111 can effectively clamp the wiping member without damaging the surface to be cleaned; and the flexible member 2111 itself has a certain flexibility, which can adaptively adjust the contact mode with the wiping member according to different characteristics of the wiping member such as shape, material and thickness. For example, for soft and thin wiping cloth, the flexible member 2111 can adhere to the surface thereof to increase the contact area and thus apply more uniform clamping force; and for wiping block which is slightly thicker or irregular in shape, the flexible member 2111 can also wrap the wiping member by deforming itself to ensure that the wiping member is stably clamped. At the same time, when releasing the wiping member, the flexible member 2111 can gently release the wiping member by virtue of its flexibility, avoiding scratching and tearing the wiping member, prolonging the service life of the wiping member, and reducing the cleaning cost to some extent.

[0100] In some embodiments, the driving part 3 comprises a sleeve 31 movably sleeved on the cleaning rod 1; the sleeve 31 is connected with the clamping structure; when the sleeve 31 moves in the axial direction of the cleaning rod 1, the clamping structure can be switched between the clamping state and the open state. The sleeve 31 driving part 3 has many advantages. On the one hand, compared with the complex multi-component transmission driving mode, it has a relatively simple structure, is easy to manufacture and assemble, and can effectively control the cost; on the other hand, the sleeve 31 is moved in the axial direction, which is intuitive and convenient, and the user only needs to push or pull the sleeve 31 along the cleaning rod 1 to easily complete the clamping or releasing operation of the wiping member, without complex operation procedures and skills, greatly improving the convenience and cleaning efficiency of the operation. At the same time, the sleeving connection of the sleeve 31 and the cleaning rod 1 makes the whole driving system more compact, does not occupy too much space, helps to maintain the rationality and aesthetics of the overall structure of the cleaning device, and is relatively stable and reliable, and is not prone to failure problems caused by complex transmission structure, ensuring long-term stable operation of the cleaning device.

[0101] In some embodiments, the fixing member 212 is further provided with a mounting member 2121, and the movable member 211 is rotatably arranged on the mounting member 2121; when the driving part 3 moves in the axial direction of the cleaning rod 1, the movable member 211 can rotate on the mounting member 2121, and then one end of the movable member 211 can move close to or away from the fixing member 212. By arranging the movable member 211 to rotate relative to the fixing member 212, one end of the movable member 211 can move away from or close to the fixing member 212, and this mounting method is simple, and the movement of the movable member 211 is more stable and accurate.

[0102] Further, the first rotating structure is arranged on the mounting member 2121; the mounting member 2121 includes two mounting plates arranged oppositely, and a hanging rod or a rotating shaft is arranged between the two mounting plates, and two ends of the hanging rod or the rotating shaft are connected to the two mounting plates respectively.

[0103] The application further discloses some embodiments, the fixing member 212 includes a fixing plate; the movable member 211 includes a movable plate, and the movable plate is arranged on one side of the fixing plate; when the driving part 3 moves in the axial direction of the cleaning rod 1, one end of the movable plate can move away from or close to the fixing plate, so that the clamping structure can switch between the clamping state and the open state; and the surface of the fixing plate facing the movable plate is provided with clamping teeth.

[0104] The application further discloses some embodiments, the surface of the movable plate facing the fixing plate is provided with clamping teeth. By adopting the design of the clamping teeth, the clamping of the wiping member can be more compact and firm, so that the wiping member can be prevented from falling off during use; and the wiping member can be smoothly gripped during gripping, so that the wiping member can be prevented from sliding and causing failure to grip. In the application, the clamping teeth can be arranged on the fixing plate alone, or the clamping teeth can be arranged on the movable plate alone, or the clamping teeth can be arranged on both the fixing plate and the movable plate; and the clamping teeth of the two can be arranged in a staggered manner or in a relative arrangement.

[0105] Further, the clamping teeth are arranged on the flexible member, so that when the wiping member is gripped, the friction between the wiping member and the clamping teeth can be increased, and the wiping member can be effectively gripped.

[0106] Further, the clamping teeth can include a plurality of protrusions, and the top of each protrusion is a sharp end, which can assist the clamping structure in gripping the wiping member, and further improve the gripping and clamping of the wiping member.

[0107] In some embodiments, the movable member 211 includes a first movable member 211 and a second movable member 211; the first movable member 211 and the second movable member 211 are respectively located on two sides of the fixed member 212 and cooperates with the two sides of the fixed member 212 to form two clamping structures; one end of the first movable member 211 and the second movable member 211 can be away from or close to the fixed member 212, so that the two clamping structures on the two sides of the fixed member 212 can be switched between the clamping state and the open state; the two clamping structures formed on the two sides of the fixed member 212 can jointly clamp the same wiping member; by using the two clamping structures formed on the two sides of the fixed member 212 to jointly clamp the same wiping member, multi-point clamping can be formed, and this multi-point clamping mode can make the wiping member receive more uniform and stable clamping force in all directions, greatly reducing the possibility of loosening, displacement or even falling of the wiping member caused by external force (such as friction force during wiping, inertial force generated by movement of the cleaning head, etc.) during cleaning, and ensuring that the wiping member is always firmly fixed on the cleaning head, thereby ensuring the continuous and efficient development of cleaning work. The two movable members 211 are close to each other during clamping because the fixed member 212 is located between the two movable members 211; and the two movable members 211 are away from each other during opening. Both the first movable member 211 and the second movable member 211 include a flexible member 2111.

[0108] Further, in the present application, one movable member 211 can be used, which is located on one side of the fixed member 212; the movable member 211 can grab the wiping member during movement to clamp the wiping member between the movable member 211 and the fixed member 212.

[0109] In some embodiments, the two clamping structures formed on the two sides of the fixed member 212 can clamp one wiping member respectively. When the clamping structures formed on the two sides of the fixed member 212 can clamp one wiping member respectively, different types of wiping members or the same type of wiping members can be clamped, thereby realizing the flexibility of wiping.

[0110] In some embodiments, one end of the movable member 211 is provided with a scraping strip, and the scraping strip can scrape the surface to be cleaned; by providing the scraping strip at one end of the movable member 211, the scraping strip can also clean the surface to be cleaned in the absence of the wiping member. The scraping head forms the flexible member 2111, and when the surface to be cleaned is scraped, the surface to be cleaned will not be damaged, and the shape of the surface to be cleaned can be adapted to improve the cleaning effect.

[0111] In some embodiments, the fixed member 212 is a rigid member, and the cooperation of the rigid member and the flexible member 2111 can effectively ensure the fastening and stability of clamping; and prevent deformation during clamping to cause the wiping member to be unable to be clamped.

[0112] In some embodiments, the limiting structure 22 is used to limit the clamping structure so that the clamping structure is in the clamping state; when the driving part 3 moves in the axial direction of the cleaning rod 1, the clamping structure can be driven to move relative to the limiting structure 22 so that the clamping structure can be limited by the limiting structure 22 or released from the limitation of the limiting structure 22, thereby enabling the clamping structure to switch between the clamping state and the open state.

[0113] In some embodiments, the clamping structure is provided with a tensioning member, i.e., an elastic member; when the clamping structure is limited by the limiting structure 22, the limiting structure 22 drives the clamping structure to switch to the clamping state, and at the same time drives the elastic member to store energy; when the clamping structure is released from the limitation of the limiting structure 22, the elastic member releases the stored energy, thereby driving the clamping structure to switch from the clamping state to the open state.

[0114] In some embodiments, the movable member 211 further includes a rigid mounting part 2112, and the flexible member 2111 is arranged on the rigid mounting part 2112; the elastic member is arranged between the rigid mounting part 2112 and the fixed member 212.

[0115] In some embodiments, the elastic member is arranged between the fixed member 212 and the movable member 211; when the clamping structure is limited by the limiting structure 22, the limiting structure 22 drives the movable member 211 to move towards the fixed member 212, and at the same time drives the elastic member to store energy; so that the clamping structure switches to the clamping state; when the clamping structure is released from the limitation of the limiting structure 22, the elastic member releases the stored energy, which can drive the movable member 211 to move away from the fixed member 212, thereby enabling the clamping structure to switch from the clamping state to the open state.

[0116] In some embodiments, when the clamping structure is in the clamping state, the cleaning head can rotate relative to the cleaning rod 1; when the clamping structure is in the open state, the cleaning head remains relatively stationary relative to the cleaning rod 1. When the clamping structure is in the clamping state, i.e., the wiping member has been clamped and is ready for cleaning, the cleaning head can rotate relative to the cleaning rod 1, which makes it easy for the user to adjust the angle of the cleaning head according to the shape and angle of the cleaning surface during cleaning. When the clamping structure is in the open state, the cleaning head remains relatively stationary relative to the cleaning rod 1, which enables the clamping structure to clamp the wiping member smoothly.

[0117] In some embodiments, when the clamping structure is in the clamping state, the limiting structure 22 and the clamping structure can rotate synchronously relative to the cleaning rod 1, so that the cleaning head can rotate relative to the cleaning rod 1; when the clamping structure is in the open state, the limiting structure 22 and the clamping structure limit each other relative to the rotation of the cleaning rod 1, so that the cleaning head remains relatively stationary relative to the cleaning rod 1. The synchronous rotation of the limiting structure 22 and the clamping structure makes the product more integral and stable. During the rotation of the cleaning head, the limiting structure 22 and the clamping structure rotate synchronously, and they jointly bear the external force generated by rotation and the external force generated by the cleaning action. In the open state, the mutual limiting keeps stationary, effectively preventing unnecessary friction, collision and other situations caused by relative rotation between components when rotation is not required.

[0118] In some embodiments, when the clamping structure is provided with a first rotating structure, the limiting structure 22 is rotatably connected to the cleaning rod 1 through a second rotating structure; when the clamping structure is in the clamping state, the centers of rotation of the first rotating structure and the second rotating structure are coaxially arranged, so that the limiting structure 22 and the clamping structure can rotate synchronously relative to the cleaning rod 1; when the clamping structure is in the open state, the centers of rotation of the first rotating structure and the second rotating structure are arranged in a staggered manner, so that the clamping structure and the limiting structure 22 can limit each other relative to the rotation of the cleaning rod 1.

[0119] Further, the driving part 3 can drive the clamping structure to move between the first position and the second position when the cleaning rod 1 is active; when the clamping structure moves to the first position of the cleaning rod 1, the clamping structure is in the open state, and the limiting structure 22 limits the rotation of the cleaning part 21 relative to the cleaning rod 1; when the clamping structure moves to the second position of the cleaning rod 1, the limiting structure 22 limits the clamping structure, so that the clamping structure is in the clamping state, and the limiting of the rotation of the cleaning part 21 relative to the cleaning rod 1 by the limiting structure 22 is released.

[0120] The application also discloses some embodiments of the limiting structure 22, which comprises a limiting shell.

[0121] The application also discloses some embodiments of the limiting structure 22, which comprises a limiting shell. The application also discloses some embodiments of the limiting structure 22, which comprises a limiting shell. The protruding part can be a flexible piece; the flexible piece can be a scraping strip. The protruding part can clean the surface to be cleaned; the protruding part can also be other cleaning pieces, such as a brush, a scraping strip, etc. Preferably, the protruding part is a sheet structure, which is convenient for grabbing the wiping piece and can also clean the surface to be cleaned.

[0122] In some embodiments, a guide rail is arranged in the limiting shell, and a guide element is arranged on the clamping structure and movably arranged on the guide rail to guide the limiting portion to enter or exit the limiting shell.

[0123] Further, the guide rail comprises a guide groove, and the guide element comprises a limiting protrusion; the limiting protrusion is movably arranged in the guide groove, and the side wall of the guide groove forms a protruding portion. The guide groove extends in the axial direction of the cleaning rod 1, and the extension direction of the guide groove can guide the movement of the limiting protrusion, so that the cleaning part 21 can move between the first position and the second position to guide the limiting portion to enter or exit the limiting shell; at the same time, the side wall of the guide groove cooperates with the limiting protrusion to limit the rotation of the clamping structure relative to the cleaning rod 1.

[0124] In some embodiments, the clamping structure has a clamping state capable of clamping the wiping member and an open state capable of releasing the wiping member; the clamping structure has a limiting portion capable of entering or exiting a limiting shell; in the process of entering the limiting shell, the inner wall of the limiting shell can limit the limiting portion to switch the clamping structure from the open state to the clamping state, thereby gradually clamping the wiping member; in the process of exiting the limiting shell, the limiting portion gradually escapes from the limiting of the limiting shell to switch the clamping structure from the clamping state to the open state, thereby gradually releasing the wiping member. When the limiting portion enters the limiting shell, the inner wall of the limiting shell limits the limiting portion, prompting the clamping structure to switch from the open state to the clamping state and gradually clamp the wiping member. This gradual clamping method has many benefits. First, it can ensure that the wiping member is uniformly stressed during clamping, avoiding the situation that the wiping member is locally deformed, damaged or clamped insecurely due to instantaneous large force clamping.

[0125] Further, the limiting portion is a rigid mounting portion 2112, and the extending portion is a flexible member 2111. The limiting portion is designed as a rigid mounting portion 2112, which can provide stable and accurate limiting effect when interacting with the limiting shell. The rigid structure has stability in shape and size and is not easy to deform, and it can accurately control the switching of the state of the clamping structure according to the inner wall of the limiting shell during its entry and exit from the limiting shell. The extending portion adopts a flexible member 2111, which brings great flexibility to the clamping of the wiping member. The flexible member 2111 itself has a deformable property and can adaptively adjust the contact mode with the wiping member according to different characteristics such as the shape, material and thickness of the wiping member.

[0126] In some embodiments, the limiting shell and the clamping structure are arranged at the same end of the cleaning rod 1; the limiting shell is movably connected with the cleaning rod 1, so that the limiting part can enter and exit the limiting shell; the limiting shell can make the limiting part enter and exit the limiting shell when the limiting shell moves on the cleaning rod 1. The movement process of the limiting shell on the cleaning rod 1 can be accurately controlled.

[0127] In some embodiments, the clamping structure is movably connected with the cleaning rod 1, so that the limiting part can enter and exit the limiting shell. When the clamping structure moves on the cleaning rod 1, the clamping structure can drive the limiting part to enter and exit the limiting shell, so that the limiting part can be clamped and limited by the limiting shell or be released from the limitation of the limiting shell.

[0128] In some embodiments, the driving part 3 is connected with the clamping structure; the driving part 3 moves on the cleaning rod 1 and can drive the clamping structure to move, so that the limiting part enters and exits the limiting shell. The relative movement between the driving part 3 and the clamping structure can ensure that the limiting part enters and exits the limiting shell smoothly.

[0129] In some embodiments, the driving part 3 is connected with the limiting shell; the driving part 3 moves on the cleaning rod 1 and can drive the limiting shell to move, so that the limiting part enters and exits the limiting shell. The relative movement between the driving part 3 and the clamping structure can ensure that the limiting part enters and exits the limiting shell smoothly.

[0130] In the present application, the limiting part and the extending part are respectively located at two ends of the clamping structure in the path of the clamping structure entering and exiting the limiting shell, that is, when one end (the limiting part) is limited in the limiting shell, the other end (the extending part) is clamped; when one end (the limiting part) is released from the limitation of the limiting shell, the other end (the extending part) is opened.

[0131] In the present application, the specific working process is as follows:

[0132] The driving part 3 moves in the axial direction of the cleaning rod 1, which can drive the clamping structure to move in the axial direction of the cleaning rod 1, so that the limiting part on the clamping structure enters and exits the limiting shell; when the clamping structure moves to the second position, the limiting part of the clamping structure enters the limiting shell, the clamping structure is clamped and limited by the two opposite inner side walls of the limiting shell, so that the clamping structure is in the clamping state, at this time, the clamping structure can clean the surface to be cleaned whether it clamps the wiping member or not; at the same time, at this position, the cleaning head (the clamping structure and the limiting shell) can rotate relative to the cleaning rod 1; the user can switch the angle between the cleaning head and the cleaning rod 1 according to the need.

[0133] When the driving part 3 drives the clamping structure to move to the first position, the clamping structure is separated from the limiting shell for clamping and limiting, so that the clamping structure is in the open state, at this time, the clamping structure can start to grab the wiping member, ready for subsequent clamping; at the same time, the inner wall at both ends of the limiting shell limits the rotation of the clamping structure relative to the cleaning rod 1, and the clamping structure can also limit the rotation of the limiting shell relative to the cleaning rod 1, at this time, the cleaning part 21, that is, the clamping structure and the limiting shell, cannot rotate relative to the cleaning rod 1.

[0134] The driving part 3 drives the clamping structure to move between the first position and the second position, so that the clamping structure can be switched between the open state and the clamping state, so as to grab, clamp, release and grab the wiping member repeatedly, and ensure that the clamping structure can clean the surface to be cleaned when in the clamping state, at this time, the entire cleaning head can rotate relative to the cleaning rod 1, and the rotating cleaning head can be rotated according to different cleaning environments.

[0135] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
