[0011] Advantages: The sleeve type driving part 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 is operated in the axial direction, which is intuitive and convenient. The user only needs to push and pull the sleeve along the cleaning rod to easily complete the clamping or releasing operation of the wiping member without complex operation process and skill, greatly improving the convenience and cleaning efficiency of the operation. At the same time, the sleeve and the cleaning rod are connected in a sleeved manner, so that the entire driving system is more compact and does not occupy too much space, which 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.

[0012] Further, the clamping structure is provided with a first rotating structure, and the clamping structure is rotatably connected with the driving part through the first rotating structure, so that the clamping structure can rotate relative to the driving part.

[0013] Advantages: The clamping structure is rotatably connected with the driving part, so that the clamping structure can switch the cleaning angle when cleaning the surface to be cleaned, and can clean the surface to be cleaned in any corner. This scheme is more flexible and convenient for cleaning.

[0014] Further, the first rotating structure includes a rotating shaft, and the driving part is provided with a shaft hole, and the rotating shaft is rotatably arranged in the shaft hole, so that the clamping structure is rotatably arranged on the driving part.

[0015] Advantages: The cooperation of the rotating shaft and the shaft hole enables the clamping structure to be rotatably arranged on the driving part. This installation method is simple and stable in rotation.

[0016] Further, the first rotating structure includes a hanging rod, and the driving part is provided with a hook, and the hanging rod is rotatably hung on the hook, so that the clamping structure is rotatably arranged on the driving part.

[0017] Advantages: This arrangement enables the clamping structure to be more conveniently installed on the driving part, and the clamping structure can be disassembled for later replacement and maintenance. In addition, the connection between the hanging rod and the hook is relatively stable, and even if a certain external force is applied during normal cleaning operation, such as pressing the cleaning head too hard during wiping or slightly oversteering when rotating the cleaning head, the connection will not easily loosen or come off.

[0018] Further, the fixing member is further provided with a mounting member, and the movable member is rotatably arranged on the mounting member; when the driving part moves in the axial direction of the cleaning rod, the movable member rotates on the mounting member, and then the one end of the movable member approaches or moves away from the fixing member.

[0019] Beneficial effects: through the rotating arrangement of the movable part and the relatively fixed part, one end of the movable part can be away from or close to the relatively fixed part, this installation method is simple, and the movement of the movable part is more stable and accurate.

[0020] Further, the fixed part comprises a fixed plate; the movable part comprises a movable plate, which is arranged on one side of the fixed plate; when the driving part moves in the axial direction of the cleaning rod, one end of the movable plate can be away from or close to the fixed plate, so that the clamping structure is switched between the clamping state and the open state.

[0021] The surface of the fixed plate facing the movable plate is provided with clamping teeth; and / or, the surface of the movable plate facing the fixed plate is provided with clamping teeth.

[0022] Beneficial effects: the design of clamping teeth can make the clamping of the wiping member more tight and firm, preventing it from falling off during use; it is also convenient for the wiping member to be grabbed smoothly during grabbing, preventing it from sliding off and causing failure to grab.

[0023] Further, the movable part comprises a first movable part and a second movable part; the first movable part and the second movable part are respectively located on both sides of the fixed part and cooperated with both sides of the fixed part to form two clamping structures; one end of the first movable part and the second movable part can be away from or close to the fixed part, so that the two clamping structures on both sides of the fixed part can be switched between the clamping state and the open state.

[0024] The two clamping structures formed on both sides of the fixed part can jointly clamp one wiping member;

[0025] Alternatively, the two clamping structures formed on both sides of the fixed part can clamp one wiping member respectively.

[0026] Beneficial effects: the two clamping structures formed on both sides of the fixed part can jointly clamp one wiping member, which can form multi-point clamping; this multi-point clamping method 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 off of the wiping member due to external forces (such as friction force during wiping, inertial force generated by the movement of the cleaning head, etc.) during cleaning, ensuring that the wiping member is always firmly fixed on the cleaning head and ensuring the continuous and efficient development of cleaning work; when the clamping structures formed on both sides of the fixed part can clamp one wiping member respectively, different types of wiping members or the same type of wiping members can be clamped, realizing the flexibility of wiping.

[0027] Further, one end of the movable part is provided with a scraping strip, which can scrape the surface to be cleaned.

[0028] And / or, the fixed part is a rigid part.

[0030] Further, the cleaning head further comprises a limiting structure arranged on the cleaning rod; the limiting structure is used for limiting the clamping structure so that the clamping structure is in the clamping state; when the driving part moves in the axial direction of the cleaning rod, the clamping structure and the limiting structure are relatively moved to enable the clamping structure to be limited by the limiting structure or to be released from the limitation of the limiting structure, so that the clamping structure is switched between the clamping state and the open state.

[0031] Beneficial effects: The state switching is orderly: when the driving part moves in the axial direction of the cleaning rod, the clamping structure and the limiting structure are relatively moved to determine whether the clamping structure is limited by the limiting structure, so that the clamping structure is switched between the clamping state and the open state. This design makes the state switching clear and orderly. The user can clearly know when the clamping structure is limited in the stable clamping state and when the clamping structure can be released to be open, which facilitates the installation and replacement of the wiping piece and avoids operation confusion or mistakes caused by unclear state switching. The application can also improve the convenience and intuitiveness of operation: compared with the cleaning device without the limiting structure, the user does not need to rely on experience or complex judgment to confirm whether the clamping structure is clamped in place or whether the wiping piece can be smoothly released. As long as the user feels different stages of relative movement of the clamping structure and the limiting structure driven by the driving part, the state switching can be easily completed. The whole operation is more intuitive and convenient. Whether a novice or a person who often uses a cleaning tool can quickly get started, reduces the learning cost and improves the use efficiency of the cleaning device.

[0032] Further, the clamping structure is provided with an elastic member; when the clamping structure is limited by the limiting structure, the limiting structure drives the clamping structure to switch to the clamping state and drives the elastic member to store energy; when the clamping structure is released from the limitation of the limiting structure, the elastic member releases the energy, thereby driving the clamping structure to switch from the clamping state to the open state.

[0033] Beneficial effects: This driving method relying on the release of the elastic potential energy of the elastic member makes the opening action more natural and smooth, avoiding the situation of jamming or incomplete opening caused by simply manually operating the driving part. It can ensure accurate switching of the clamping structure between the two states.

[0034] Further, the movable piece further comprises a rigid mounting part, and the flexible piece is arranged on the rigid mounting part; the elastic member is arranged between the rigid mounting part and the fixed piece.

[0036] Further, the elastic part is arranged between the fixing part and the movable part; when the clamping structure is limited by the limiting structure, the limiting structure drives the movable part to move towards the fixing part, and simultaneously drives the elastic part to store energy; so that the clamping structure switches to the clamping state; when the clamping structure is released from the limiting of the limiting structure, the elastic part releases the force, and can drive the movable part to move away from the fixing part, and then the clamping structure switches from the clamping state to the open state.

[0037] Beneficial effects: The elastic force of the elastic part can drive the movable part to move, so as to switch the state of the clamping structure. This way can realize stable and accurate switching of the clamping structure.

[0038] Further, the limiting structure includes a limiting shell; the limiting shell is arranged on the cleaning rod; the limiting shell has an opening; the clamping structure has an extending part and a limiting part, the extending part always extends out of the opening; the inner wall of the limiting shell is used to limit the limiting part, so that the clamping structure is in the clamping state; when the driving part moves in the axial direction of the cleaning rod, it can drive the limiting part to enter or exit the limiting shell, and then the clamping structure can be limited in the limiting shell or released from the limiting shell.

[0039] Beneficial effects: The inner wall of the limiting shell limits the limiting part of the clamping structure, so as to ensure that the clamping structure can stably be in the clamping state. This way of limiting by the inner wall of the entity structure can provide clear and accurate limiting effect, so that the wiping part can be firmly kept in the clamping state during the cleaning process, regardless of any external force interference such as friction force generated by wiping action, shaking caused by movement of the cleaning head, etc., so as to avoid the wiping part from being loose, displaced or falling off, and thus to stably ensure the efficient development of the cleaning work and the consistency of the cleaning quality.

[0040] Further, a guide rail is arranged in the limiting shell, and a guide part is arranged on the clamping structure, the guide part is movably arranged on the guide rail to guide the limiting part to enter or exit the limiting shell.

[0041] Beneficial effects: The guide part moves on the guide rail to guide the limiting part to enter or exit the limiting shell, so that the clamping structure stably moves in the limiting shell, preventing the movement deviation between the two from affecting the working stability of the clamping structure.

[0042] Further, a locking structure is arranged on the cleaning rod; the locking structure is used to lock or unlock the driving part.

DETAILED DESCRIPTION

[0081] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. 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 the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0082] The embodiments of the utility model will be described below in combination with Figures 1 to 10

[0083] The utility model discloses a cleaning device, including cleaning head and cleaning rod 1, and the cleaning head includes cleaning part 21, and the cleaning part 21 is used to clean the surface to be cleaned, and the surface to be cleaned can include ground, glass surface, desktop and so on any surface, and the surface to be cleaned can be the smooth or rough surface plane, and also can be the smooth or rough curved surface and so on any surface.

[0084] The application also 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, and the limiting structure 22 can be movably connected with the cleaning rod 1 and can move relative to the cleaning rod 1.

[0085] The application also discloses some embodiments, and 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 limit 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, which can ensure that the cleaning part 21 works stably under certain conditions, can effectively resist external interference, and can maintain a stable state of the cleaning head, and the cleaning head will not easily rotate due to accidental stress, which can affect the accuracy and cleaning effect. When the cleaning part 21 moves to the second position, the limiting structure 22 removes the rotation limit of the cleaning part 21 relative to the cleaning rod 1, and the cleaning head can rotate freely according to the shape of the cleaning object, which greatly enhances the flexibility of the cleaning device. And the relative movement of the cleaning part 21 and the cleaning rod 1 realizes the fixation of the cleaning part 21 and the rotation of the cleaning head, and this mode is simple in operation, high in visualization and convenient for users to use. In the embodiment, the cleaning part 21 can be a cloth head, a scraping head with a scraping head, a brush head and any cleaning head.

[0086] ​The application further discloses some embodiments, when the cleaning part 21 is in the second position, the limiting structure 22 can rotate synchronously with the cleaning part 21 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.

[0087] Further, when the cleaning part 21 is in the second position, the rotation center of the cleaning part 21 and the limiting structure 22 is 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.

[0088] 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 in the clockwise and counterclockwise directions relative to the cleaning rod 1, so that the relative rotation between the cleaning part 21 and the cleaning rod 1 can be effectively prevented.

[0089] 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 edge 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 disengaged from the limiting of the hooks, so that the rotation of the cleaning part 21 relative to the cleaning rod 1 can be limited.

[0090] Further, at least one of the two opposite limiting parts 221 can be a plane, the plane is shaped as a plane opposite to the side surface of the cleaning part 21 in the rotation direction of the cleaning part 21 relative to the cleaning rod 1, so as to limit the rotation of the cleaning part 21 relative to the cleaning rod 1. For example, one of the two limiting parts 221 is a plane opposite to the side surface of the cleaning part 21, and the other is a hook or other limiting structure 22 capable of clamping the cleaning part 21. Alternatively, the two limiting parts 221 are both planes, and the two planes are shaped as planes opposite to the side surfaces of the cleaning part 21 in the rotation direction of the cleaning part 21 relative to the cleaning rod 1. The two planes are used to limit the rotation of the cleaning part 21, so that the limiting effect is good, and the service life is long.

[0091] In some embodiments, the limiting protrusion is arranged on the cleaning part 21, and at least one limiting part 221 is shaped as a protruding part opposite to the side surface of the limiting protrusion in the rotation direction of the cleaning part 21 relative to the cleaning rod 1, so as to limit the rotation of the cleaning part 21 relative to the cleaning rod 1. The limiting protrusion and the protruding part are used to limit the rotation, so that the manufacturing is simple, the cost is low, and the limiting effect is good.

[0092] Further, the protrusion can be a baffle, which cooperates with the limiting protrusion to limit the rotation of the cleaning part 21 relative to the cleaning rod 1. The baffle can be provided as a strip-shaped baffle, further improving the reliability of the product.

[0093] The application also discloses some embodiments, wherein the cleaning part 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; and 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 part 21, so that the wiping member can be replaced more conveniently, the use is more convenient, and the application scenarios are more flexible.

[0094] The application also discloses some embodiments, wherein the limiting structure 22 can limit the clamping structure, so that the clamping structure is 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 limitation of the limiting structure 22, and then enable the clamping structure to switch 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; and the relative movement between the clamping structure and the limiting structure 22 can enable the clamping structure to be limited and released from the limitation, and then switch between the clamping state and the open state, which greatly facilitates the replacement operation of the wiping member.

[0095] Further, the clamping structure comprises two clamping members which can move close to or away from each other, so that the clamping structure can be switched 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 the clamping structure has a wiping function.

[0096] In some embodiments, when the cleaning part 21 moves to a first position on the cleaning rod 1, the two clamping members move away from each other, and the clamping structure switches to the open state; when the cleaning part 21 moves to a second position on the cleaning rod 1, the two clamping members move close to each other, and the clamping structure switches to the clamping state, so as to be able to clamp the wiping member. When the clamping structure clamps the wiping member, the cleaning part 21 is relatively stationary relative to the cleaning rod 1, so as to facilitate the clamping of the wiping member; after the clamping is completed, the cleaning part 21 can rotate relative to the cleaning rod 1, which can be applied to different wiping scenes, is more flexible to use, and has more application scenarios.

[0097] In some embodiments, the limiting structure 22 comprises two converging heads 222 located on both sides of the two clamping members; the two converging heads 222 are used to clamp and limit the clamping structure, so that the clamping structure is in the clamped state. When the cleaning part 21 moves to the first position on the rod body 11, the two clamping members are 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 converging heads 222, so that the two clamping members are close to each other, thereby making the clamping structure in the clamped state. The two converging heads 222 are used to make the two clamping members close to each other, which is more stable and can prevent the clamping members from being opened due to misoperation.

[0098] 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 converging heads 222 are respectively inner wall surfaces of the limiting structure 22 located on both sides of the two clamping members. The inner wall of the limiting shell forms the two converging heads 222, which is convenient to manufacture and install.

[0099] In some embodiments, the limiting structure 22 comprises two opposite limiting parts 221, which are two wall surfaces of the limiting shell respectively adjacent to the two converging heads 222. The limiting structure 22 can limit the rotation of the cleaning part 21 relative 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.

[0100] Some embodiments of the present application also disclose that the cleaning part 21 is provided with a limiting protrusion, and the inner wall of the limiting shell is provided with a guide groove; when the cleaning part 21 moves to the second position on the cleaning rod 1, the limiting protrusion is located in the guide groove, and the side wall of the guide groove forms the limiting part 221. The concave-convex cooperation is simple in structure, convenient to manufacture, and good in limiting effect.

[0101] In some embodiments, the guide groove extends in the axial direction of the cleaning rod 1, and can guide the movement of the cleaning part 21 in the axial direction of the cleaning rod.

[0102] Some embodiments of the present application also disclose that the cleaning part 21 is further provided with a tension member; when the cleaning part 21 moves from the first position to the second position on the rod body 11, the tension member can drive the two clamping members to be away from each other, so that the clamping members can be opened, and the wiping member can be easily grabbed.

[0103] Further, the tension member comprises an elastic member. The elastic member can be an elastic block, a rubber block or the like.

[0104] The application further discloses some embodiments, wherein the cleaning rod 1 is provided with a movable driving part 3; the driving part 3 is movable 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; however, 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 located at different positions in the axial direction of the cleaning rod 1.

[0105] In some embodiments, the driving part 3 is rotationally connected with the cleaning part 21; further, the lower end of the driving part 3 is rotationally connected with the cleaning part 21. Further, the driving part 3 is rotationally connected with the cleaning part 21 through a first rotation structure.

[0106] In some embodiments, the limiting structure 22 is rotationally connected with the cleaning rod 1, and further, the limiting structure 22 is connected with the cleaning rod 1; when the cleaning part 21 moves to the first position on the cleaning rod 1, the rotation centers of the first rotation structure and the second rotation structure are arranged in a staggered manner, so that the clamping structure and the limiting structure 22 can limit the rotation of each other relative to the cleaning rod 1; when the cleaning part 21 moves to the second position on the cleaning rod 1, the rotation centers of the first rotation structure and the second rotation structure are arranged in a coaxial manner, so that the limiting structure 22 and the clamping structure can rotate synchronously relative to the cleaning rod 1.

[0107] In some embodiments, the clamping structure is provided with a first rotation structure, and the clamping structure is rotationally connected with the driving part 3 through the first rotation structure, so that the clamping structure can rotate relative to the driving part 3.

[0108] In some embodiments, the first rotation structure comprises a rotating shaft, the driving part 3 is provided with a shaft hole, and the rotating shaft is rotationally arranged in the shaft hole, so that the clamping structure is rotationally arranged on the driving part 3.

[0109] In some embodiments, the first rotation structure comprises a hanging rod, the driving part 3 is provided with a hook 32, and the hanging rod is rotationally hung on the hook 32, so that the clamping structure is rotationally arranged on the driving part 3.

[0110] In some embodiments, the cleaning rod 1 comprises a rod body 11 and a fixing sleeve 12, the fixing sleeve 12 is sleeved on one end of the rod body 11; and the driving part 3 is movably arranged on the fixing sleeve 12.

[0111] In some embodiments, the driving part 3 can be a driving block, an axially extending guide groove is arranged on the cleaning rod 1, the driving block is movably arranged in the guide groove, a through hole 312 is arranged on the groove bottom of the guide groove, a connecting rod is arranged in the rod body 11, one end of the connecting rod is connected with the driving block, and the other end of the connecting rod is connected with the cleaning part 21; the structure is simple, and the driving effect is good.

[0112] 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 cleaning part 21.

[0113] In some embodiments, the driving part 3 and the cleaning rod 1 have a rotation-stopping structure to limit the rotation of the driving part 3 relative to the cleaning rod 1. During the cleaning process, the user usually needs to push or pull the driving part 3 in a specific direction to control the relevant functions of the cleaning device, such as clamping or loosening the clamping structure, etc. The rotation-stopping structure limits the rotation of the driving part 3 relative to the cleaning rod 1, so that the movement of the driving part 3 is constrained in the axial direction, and the user can more accurately control the direction of the operation, avoiding operation errors caused by accidental rotation of the driving part 3.

[0114] In some embodiments, one end of the rod body 11 has a fixing sleeve 12 with a polygonal cross section; the driving part 3 is a sleeve 31 movably sleeved outside the fixing sleeve 12, the inner wall of the sleeve 31 is matched with the shape of the fixing sleeve 12, and the two form a rotation-stopping structure to prevent the driving part 3 from rotating relative to the cleaning rod 1. By designing the fixing sleeve 12 with a polygonal cross section and matching the shape of the inner wall of the sleeve 31, the closely matched structure forms an extremely effective rotation-stopping structure to prevent relative rotation between the sleeve 31 and the fixing sleeve 12.

[0115] In some embodiments, the limiting structure 22 is rotationally connected with the fixing sleeve 12 through a second rotation structure, so that the limiting structure 22 and the cleaning rod 1 can rotate relative to each other.

[0116] In some embodiments, the fixing sleeve 12 is provided with an axial extension 121, and the limiting structure 22 is arranged on the axial extension 121; when the driving part 3 comprises a sleeve 31, the sleeve 31 is sleeved outside the fixing sleeve 12; one end of the sleeve 31 is a closed end, and a through hole 312 is formed in the closed end; the axial extension 121 is movably arranged in the through hole 312; when the sleeve 31 moves on the fixing sleeve 12, the axial extension 121 moves relative to the through hole 312. The fixing sleeve 12 is provided with the axial extension 121, which 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 fixing sleeve 12. When the user operates the sleeve 31 to move axially along the fixing 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 a second rotation structure, and the second rotation structure comprises a first shaft and a second shaft arranged on the limiting structure.

[0117] In some embodiments, the axial extension section 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, which are rotatably arranged in the first hole and the second hole, so that the limiting structure 22 is rotatably arranged on the axial extension section 121. The first shaft and the second shaft cooperate with the corresponding holes, not only realizing the rotation function, but also positioning and limiting the rotation of the limiting structure 22 to a certain extent. Moreover, the arrangement of the first shaft and the second shaft forms a double-shaft support 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 rotation structure, the double-shaft structure can more evenly distribute the force on the limiting structure 22, the axial extension section 121 and other components connected thereto, avoiding the situation that stress is concentrated in a certain place and causing damage to the components.

[0118] Further, the closed end is further provided with an axial extension part 311, which is connected with the clamping structure; the axial extension part 311 is arranged between the first axial extension plate and the second axial extension plate.

[0119] The application also discloses some embodiments, wherein the cleaning rod 1 is further 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, the stable operation of the driving part 3 can be prevented from being touched by mistake.

[0120] The application also discloses some embodiments, wherein the locking structure 4 comprises a pressing piece, which 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.

[0121] In some embodiments, the pressing piece comprises a spring buckle, which is arranged on the cleaning rod 1 and can be elastically pressed on the cleaning rod 1.

[0122] 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.

[0123] The application also discloses some embodiments of the clamping structure, which comprises a movable part 211 and a fixed part 212, and the movable part 211 and the fixed part 212 form the two clamping parts which can approach or move away from each other. The movable part 211 comprises a flexible part 2111 which is used for clamping or releasing the wiping part; the cleaning head is arranged on the cleaning rod 1; the movable driving part 3 is 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, the one end of the movable part 211 can move away from or approach the fixed part 212, so that the clamping structure can be switched between the clamping state and the open state. The driving part 3 is moved in the axial direction of the cleaning rod 1, and the one end of the movable part 211 is moved away from or approaches the fixed part 212, so that the state of the clamping structure is switched, the operation is simple, the wiping part is convenient to replace, disassemble and assemble; and the clamping structure comprises the movable part 211, the movable part 211 comprises the flexible part 2111, the flexible part 2111 is used for clamping and releasing the wiping part, and the flexible part 2111 is used for grabbing when the wiping part is installed, so that the flexible part 2111 cannot cause abrasion to the grabbed surface.

[0124] When the movable part 211 is used for grabbing the wiping part, the wiping part can be laid on the surface to be cleaned or any surface, then the fixed part is pressed on the wiping part, the movable part 211 is driven to move in the direction of approaching the fixed part 212, at this time, the movable part 211 is attached to the laid wiping part, and the movable part 211 can roll up the wiping part and clamp the wiping part between the movable part 211 and the fixed part 212 in the moving process, when the movable part 211 moves to the clamping position, the fixed part 212 and the movable part 211 clamp the wiping part between them.

[0125] 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 blocks that are 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 or tearing the wiping member, prolonging the service life of the wiping member, and reducing the cleaning cost to some extent.

[0126] 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 structures, ensuring long-term stable operation of the cleaning device.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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 grabbed during grabbing, so that the wiping member can be prevented from sliding and causing failure to be grabbed. 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 can be arranged oppositely.

[0131] Further, the clamping teeth are arranged on the flexible member, so that when the wiping member is grabbed, the friction between the wiping member and the clamping teeth can be increased, and the wiping member can be effectively grabbed.

[0132] 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 grabbing the wiping member, and further improve the grabbing and clamping of the wiping member.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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; when there is no wiping member, the scraping strip can also clean the surface to be cleaned. 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.

[0137] 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.

[0138] 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 be released from the limitation of the limiting structure 22, thereby enabling the clamping structure to switch between the clamping state and the open state.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] In some embodiments, when the clamping structure is in the clamping state, the limiting structure 22 and the clamping structure can synchronously rotate relative to the cleaning rod 1, so that the cleaning head can relatively 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 and the cleaning rod 1 remain relatively stationary. The synchronous rotation of the limiting structure 22 and the clamping structure makes the product have better integrity and better stability. During the rotation of the cleaning head, the limiting structure 22 and the clamping structure synchronously rotate, and they jointly bear the external force generated by rotation and the external force brought by the wiping action during cleaning. 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 needed.

[0144] In some embodiments, when the clamping structure is provided with a first rotating structure, the limiting structure 22 and the cleaning rod 1 are rotatably connected through a second rotating structure; when the clamping structure is in the clamping state, the rotation centers of the first rotating structure and the second rotating structure are coaxially arranged, so that the limiting structure 22 and the clamping structure can synchronously rotate relative to the cleaning rod 1; when the clamping structure is in the open state, the rotation centers 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.

[0145] 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 moves; 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 limiting structure 22 to the rotation of the cleaning part 21 relative to the cleaning rod 1 is released.

[0146] The application also discloses some embodiments of the limiting structure 22, which comprises a limiting shell.

[0147] The application also discloses some embodiments of the limiting shell, which has an opening; the clamping structure has an extending part and a limiting part, and the extending part always extends out of the opening; the inner wall of the limiting shell is used for limiting the limiting part, 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 limiting part can enter or exit the limiting shell, so that the clamping structure can be limited in the limiting shell or separated from the limiting shell.

[0148] In some embodiments, the limiting shell is provided with a guide rail, and the clamping structure is provided with a guide piece movably arranged on the guide rail, so as to guide the limiting part to enter or exit the limiting shell.

[0149] Further, the guide rail comprises a guide groove, and the guide piece comprises a limiting protrusion; the limiting protrusion is movably arranged in the guide groove, and a side wall of the guide groove forms a protruding part. 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 part to enter and 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.

[0150] The application also discloses 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 part capable of entering and exiting a limiting shell; during the process of entering the limiting shell, the inner wall of the limiting shell can limit the limiting part, so that the clamping structure switches from the open state to the clamping state, and then the clamping structure gradually clamps the wiping member; during the process of exiting the limiting shell, the limiting part gradually escapes from the limitation of the limiting shell, so that the clamping structure switches from the clamping state to the open state, and then the clamping structure gradually releases the wiping member. When the limiting part enters the limiting shell, the inner wall of the limiting shell limits the limiting part, which promotes the clamping structure to switch from the open state to the clamping state, and the wiping member is gradually clamped. This gradual clamping method has many advantages. 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.

[0151] Further, the limiting part is a rigid mounting part 2112, and the extending part is a flexible piece 2111. The limiting part is designed as a rigid mounting part 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 during the process of entering and exiting the limiting shell, it can accurately control the switching of the state of the clamping structure according to the inner wall of the limiting shell. The extending part adopts a flexible piece 2111, which brings great flexibility to the clamping of the wiping member. The flexible piece 2111 itself has a deformable characteristic 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.

[0152] 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; and the limiting shell can make the limiting part enter and exit the limiting shell when moving on the cleaning rod 1. The process of the limiting shell moving on the cleaning rod 1 can be accurately controlled.

[0153] In some embodiments, the clamping structure is movably connected with the cleaning rod 1, so that the limiting part can enter or exit the limiting shell. When the clamping structure moves on the cleaning rod 1, it can drive the limiting part to enter or exit the limiting shell, so that the limiting part can be clamped by the limiting shell or be released from the clamping of the limiting shell.

[0154] 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 or exits the limiting shell. The relative movement between the driving part 3 and the clamping structure can ensure that the limiting part enters or exits the limiting shell smoothly.

[0155] 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 or exits the limiting shell. The relative movement between the driving part 3 and the clamping structure can ensure that the limiting part enters or exits the limiting shell smoothly.

[0156] In this application, the limiting part and the extending part are respectively located at the two ends of the clamping structure in the path of the clamping structure entering or exiting the limiting shell, that is, when one end (the limiting part) is clamped in the limiting shell, the other end (the extending part) is clamped; when one end (the limiting part) is released from the clamping of the limiting shell, the other end (the extending part) is released.

[0157] In this application, the specific working process is as follows:

[0158] The driving part 3 moves in the axial direction of the cleaning rod 1 and 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 or exits the limiting shell. When the clamping structure moves to the second position, the limiting part of the clamping structure enters the limiting shell, and 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 a clamped 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.

[0159] When the driving part 3 drives the clamping structure to move to the first position, the clamping structure is released from the clamping of the limiting shell, so that the clamping structure is in an open state. At this time, the clamping structure can start to grab the wiping member in preparation for clamping it later. At the same time, the inner walls at both ends of the limiting shell limit 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 (the clamping structure and the limiting shell) cannot rotate relative to the cleaning rod 1.

[0160] 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 that the wiping member can be grabbed, clamped, released, grabbed, and so on, reciprocating work is realized, and when the clamping structure is in the clamping state, the clamping structure can clean the surface to be cleaned, at this time, the whole cleaning head can rotate relative to the cleaning rod 1, and the rotating cleaning head can be rotated according to different cleaning environments.

[0161] 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.
