[0001] This application claims priority to Chinese Patent Application No. 2024212331432, filed on May 31, 2024, entitled "A Cloth-Cloth Mop", and Chinese Patent Application No. 2024212331447, filed on the same day, entitled "A Cloth-Cloth Mop", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the technical field of household appliances, and in particular relates to a cloth-clamping mop. Background Technology

[0003] A mop is a common cleaning tool used in daily household life. It generally consists of a mop handle and a mop head that rotatably connects to the handle. The bottom of the mop head has a wiping attachment, which is used by holding the mop handle to clean the floor. After a period of use, the wiping attachment needs to be washed or replaced to keep the mop clean. Whether washing or replacing the wiping attachment, it must be removed from the mop head and then reinstalled.

[0004] A clamping mop has been proposed in related technologies, which clamps the wiping material to the bottom of the mop board. However, the operation of existing clamping mops, which switch between clamping and releasing states, is relatively complicated and not convenient for users. Utility Model Content

[0006] This utility model provides a cloth-clamping mop, comprising: A plate body, on which a clamping body is movably disposed, the clamping body being movable relative to the plate body, such that the clamping body has a loose state in which there is a clamping cavity between it and the plate body and a clamping state in which it is tightly abutting against the plate body; A transmission unit is movably disposed on the plate and connected to the clamping body in a transmission manner, used to drive the clamping body to move relative to the plate so as to switch between the released state and the clamping state; A control component is movably disposed relative to the plate body, and the control component is drively connected to the transmission part; The control component is driven to move relative to the plate for the first time, which drives the transmission part to move. The movement of the transmission part drives the clamping body to move relative to the plate so that the clamping body can switch from the released state to the clamping state. The control component is driven to move relative to the plate for the second time, which drives the transmission part to move. The movement of the transmission part drives the clamping body to move relative to the plate so that the clamping body can switch from the clamping state to the released state.

[0007] The control component of the cloth-clamping mop disclosed in this utility model has only one mode of operation. The first movement of the control component can switch the clamping body from the loose state to the clamping state, and the second movement of the control component can switch the clamping body from the clamping state to the loose state. Users only need to perform the same operation to control the cloth-clamping mop. The operation method is simple and the user experience is better.

[0008] In one feasible embodiment, the control member is driven to move relative to the plate body for the first time, driving the transmission part to move. The movement of the transmission part drives the clamping body to move relative to the plate body, causing the clamping body to switch from the released state to the clamping state and be positioned in the clamping state. The control member is driven to move relative to the plate body for the second time, driving the transmission part to move. The movement of the transmission part drives the clamping body to move relative to the plate body, causing the clamping body to switch from the clamping state to the released state and be positioned in the released state.

[0009] In one feasible embodiment, the transmission unit is rotatably disposed on the plate body; The control component is driven to move relative to the plate for the first time, causing the transmission part to rotate.

The control component is driven to move relative to the plate for the second time, causing the transmission part to rotate. The rotation of the transmission part causes the clamping body to move relative to the plate, so that the clamping body switches from the clamping state to the released state and is positioned in the released state.

The clamping body slides relative to the cam, and slides from the first protruding position to the first basic position and is positioned at the first basic position, so that the clamping body switches from the released state to the clamping state and is positioned at the clamping state. The control component is driven to move relative to the plate body for the second time, causing the cam to rotate. The clamping body continues to slide relative to the cam, and slides from the first basic position to the second protruding position and is positioned at the second protruding position, so that the clamping body switches from the clamping state to the released state and is positioned at the released state.

[0011] In one feasible embodiment, the cam is provided with an annular drive groove, the annular drive groove is arranged according to the outer contour of the cam, and has at least two base positions with the smallest radius and two protruding positions with the largest radius, and the base positions and the protruding positions are alternately distributed in the drive groove. The clamping body is provided with a drive shaft, which is inserted into the drive groove, and when the cam is driven to rotate, the drive shaft slides along the drive groove. The control component moves relative to the plate body for the first time under drive, causing the cam to rotate. The drive shaft slides along the drive groove and moves from the first protruding position of the drive groove to the first basic position and is positioned at the first basic position, so that the clamping body switches from the released state to the clamping state and is positioned at the clamping state. The control component moves relative to the plate body for the second time under drive, causing the cam to rotate. The drive shaft continues to slide along the drive groove and moves from the first basic position of the drive groove to the second protruding position and is positioned at the second protruding position, so that the clamping body switches from the clamping state to the released state and is positioned at the released state.

[0012] In one feasible embodiment, the cam is an elliptical cam, the annular drive groove is an elliptical groove, the two positions with the largest radii of the elliptical groove are the protruding positions, and the two positions with the smallest radii are the base positions.

At the same time, the drive shaft of the second clamping body slides from the second protruding position of the drive groove to the second base position and is positioned at the second base position, so that the second clamping body also switches from the released state to the clamping state and is positioned at the clamping state. The control component moves a second time relative to the plate body, causing the cam to rotate. The drive shafts of both clamping bodies continue to slide along the drive groove. The drive shaft of the first clamping body slides from the first base position of the drive groove to the second protruding position and is positioned at the second protruding position, so that the first clamping body switches from the clamping state to the released state and is positioned at the released state. At the same time, the drive shaft of the second clamping body slides from the second base position of the drive groove to the first protruding position and is positioned at the first protruding position, so that the second clamping body also switches from the clamping state to the released state and is positioned at the released state.

The second lever body is in a driving engagement with the transmission part, and the first lever body and the second lever body are drivingly connected. The first rod is driven to move towards or away from the second rod for the first time, causing the second rod to rotate for the first time. The rotation of the second rod causes the transmission part to move, and the movement of the transmission part causes the clamping body to move relative to the plate so that the clamping body can switch from the released state to the clamping state. The first rod is driven to move towards or away from the second rod for the second time, causing the second rod to rotate for the second time. The rotation of the second rod causes the transmission part to move, and the movement of the transmission part causes the clamping body to move relative to the plate so that the clamping body can switch from the clamping state to the released state.

[0015] In one feasible embodiment, the second rod body is provided with a plurality of guide spiral surfaces connected end to end at one end near the first rod body, and the end of the first rod body abuts against the first guide spiral surface among the plurality of guide spiral surfaces. The first rod is driven to move towards or away from the second rod for the first time. The end of the first rod pushes against the second rod along the first guide spiral surface, causing the second rod to rotate for the first time. After the second rod completes the first rotation, the second guide spiral surface adjacent to the first guide spiral surface comes into contact with the end of the first rod. The first rod is driven to move towards or away from the second rod for the second time. The end of the first rod pushes against the second rod along the second guide spiral surface, causing the second rod to rotate for the second time.

[0016] In one feasible embodiment, the first rod has a hollow structure, and the end of the second rod away from the plate extends into the hollow structure; and the inner wall of the hollow structure is provided with a plurality of axial grooves extending along the axial direction of the first rod and a plurality of guide spiral grooves communicating with the axial grooves, the two ends of any one guide spiral groove communicating with two axial grooves respectively, and the end of the first axial groove away from the plate communicating with the guide spiral groove, and the end of the second axial groove close to the plate communicating with the guide spiral groove; The second rod body has a shaft body that cooperates with the axial groove and the guide spiral groove at one end away from the plate body; The first rod is driven to move towards the second rod first, and then moves away from the second rod for the first time. The shaft slides along the first axial groove from one end near the plate to the other end away from the plate and enters the first guide spiral groove that communicates with the first axial groove. The shaft then slides along the first guide spiral groove to the other end near the plate and drives the second rod to rotate for the first time. After the second rod completes the first rotation, the shaft moves from the end of the first guide spiral groove near the plate to the other end of the second axial groove that communicates with the plate. The first rod is driven to move towards the second rod and then moves away from the second rod a second time. The shaft slides along the second axial groove from one end near the plate to the other end away from the plate and enters the second guide spiral groove connected to the second axial groove. The shaft then slides along the second guide spiral groove to the other end near the plate and drives the second rod to rotate a second time. After the second rod completes the second rotation, the shaft enters the third axial groove or the first axial groove near the plate from the other end of the second guide spiral groove.

[0017] In one feasible embodiment, an elastic element is provided between the first rod and the second rod; The first rod is driven to move closer to the second rod, and the elastic element compresses and stores force; the elastic element releases force, causing the first rod to move away from the second rod.

[0028] This application is described below with reference to the accompanying drawings and specific embodiments: Please refer to Figure 1 , Figure 2 This application discloses a cloth-clamping mop, including a mop head and a control lever 2. The mop head is provided with a plate 11 and a clamping body 12. Generally, the clamping body 12 is provided on the side of the plate 11, and the bottom surface is clamped with the wiping material by the clamping body 12. The plate 11 is also provided with a transmission part 13. Through the movement of the transmission part 13, the clamping body 12 can be moved closer to or away from the plate 11.

[0029] When the clamping body 12 moves away from the plate 11, the clamping of the wiping material loosens, and the wiping material can fall off from the bottom surface of the plate 11. When installing the wiping material, it is generally laid flat on the ground first, or for newly replaced wiping materials, it is usually placed in its packaging box. Then, the bottom surface of the plate 11 is pressed on the wiping material, and then the clamping body 12 is controlled to move closer to the plate 11. Since the wiping material is a flexible material, it is generally made of non-woven fabric, wiping paper, cotton cloth, etc. When the clamping body 12 moves closer to the plate 11, it will cause the wiping material to retract. Some of the wiping material will be squeezed into the cavity between the clamping body 12 and the plate 11. As the distance between the clamping body 12 and the plate 11 decreases, the cavity will gradually decrease until it disappears. At this time, the wiping material is clamped by the clamping body 12 and the plate 11 to the bottom surface of the plate 11 of the cloth mop. The user can then operate the plate 11 in various ways to clean the ground, windows, desktops, and other environments.

[0030] In this embodiment, the transmission part 13 is generally located inside the plate 11. To facilitate its movement and to ensure that it can move the clamping body 12 without affecting the normal use of other components, a control lever 2 is provided. When the control lever 2 is close to the mop head, one end of it is connected to the transmission part 13. The user can control the action by operating the control lever 2. For example, the user can rotate the control lever 2 to move the transmission part 13, or push or pull the control lever 2 to move the transmission part 13, thereby moving the clamping body 12. This method of using the control lever 2 avoids the user needing to manually change the state of the clamping body 12 to clamp the wiping material on the mop head or to make the wiping material fall off the mop head, thus avoiding direct contact between the user's hands and the mop head or the plate 11, which can improve the user experience.

[0031] Further, please refer to Figure 3 , 4 The control lever 2 has a limiting part 21 at the end near the mop head, and the transmission part 13 has a mating part 131. When the control lever 2 approaches the mop head, the limiting part 21 and the mating part 131 engage, and the mating part 131 achieves circumferential limiting with the control lever 2 through the limiting part 21. When the user operates the control lever 2 to rotate, the control lever 2 can drive the transmission part 13 to rotate, thereby driving the clamping body 12 to move away from or towards the plate 11.

[0032] Specifically, the limiting part 21 can be a protrusion along the radial direction of the control rod 2, that is, it extends out of the rod body in a plane perpendicular to the length direction of the control rod 2, and the mating part 131 is a groove that mates with the protrusion. When the control rod 2 rotates, the protrusion is locked in the groove, so that the control rod 2 and the transmission part 13 remain relatively fixed in the circumferential direction of the control rod 2, that is, when the control rod 2 is driven to rotate, it can drive the transmission part 13 to rotate.

[0033] Since the control lever 2 is frequently in motion, its position in a home environment may shift due to the user's frequency of use and usage patterns. Therefore, when the protrusion of the control lever 2 needs to enter the groove of the mating part 131, it may just touch the edge of the groove, preventing the control lever 2 from smoothly engaging with the transmission part 13. To address this, in this embodiment, a slope 211 is provided on the outer edge of the limiting part 21 on the control lever 2, and a guide surface 1311 is provided on the outer edge of the groove of the mating part 131. This allows the limiting part 21 to enter the mating part 131 and the protrusion to insert into the groove when the control lever 2 slides close to the mop head, even if the limiting part 21 and the mating part 131 are not aligned and there is a slight offset. The slope 211 can still guide the limiting part 21 into the mating part 131 through the guide surface 1311, thus allowing the protrusion to insert into the groove. The inclined surface 211 is generally a conical surface or part of a conical surface, and the guide surface 1311 is also a conical surface or part of a conical surface. In fact, the inclined surface 211 reduces the size of the limiting part 21 near the mop head, while the guide surface 1311 increases the size of the mating part 131 near the control rod 2, thereby increasing the mating allowance between the limiting part 21 and the mating part 131, which can increase the tolerance for inaccurate positioning. Specifically, along the cross section perpendicular to the length of the control lever 2, the groove can be a non-circular groove such as a cross groove, a T-shaped groove, or a rectangular groove, and the protrusion can be a non-circular protrusion such as a cross-shaped protrusion, a T-shaped protrusion, or a rectangular protrusion that mates with the groove. The common feature of the above shapes is that the radial length from their center to their edge is not uniform. Therefore, when rotating with their center as the axial direction, the protrusion engages circumferentially with the groove, thereby allowing the control lever 2 to drive the transmission part 13 to rotate. In particular, when the cross section of the protrusion is "+" shaped, it extends outward with 4 wings, and the groove is a cross groove, which can make the force applied by the control lever 2 to the transmission part 13 more uniform and improve the product life.

[0034] In some embodiments, the cloth-clamping mop is provided with a connecting rod 3, which is rotatably connected to the plate 11, such as by a hinge. The connecting rod 3 and the control rod 2 are generally located on the top surface of the plate 11, that is, on the same side of the plate 11. Since both the connecting rod 3 and the control rod 2 are rods, when the control rod 2 slides relative to the connecting rod 3, it can move closer to or further away from the mop head.

[0035] Specifically, the connecting rod 3 can be a sleeve 32, and the control rod 2 is set inside the sleeve 32 and can slide along the length of the sleeve 32. At this time, the connecting rod 3 and the control rod 2 are coaxial, and the user can hold the connecting rod 3 or the control rod 2 to use the cloth clip mop.

[0036] like Figure 5 , 6 To facilitate the sliding of the control rod 2 within the sleeve 32 without it coming off, the end of the connecting rod 3 away from the mop head is generally provided with a locking ring 31. The inner diameter of the locking ring 31 is smaller than the inner diameter of the sleeve. The control rod 2 includes a flange 22 located within the sleeve. The diameter of the control rod 2 at the flange 22 is between the inner diameter of the sleeve and the inner diameter of the locking ring 31. The diameter of the part of the control rod 2 located on the upper side of the flange 22 needs to be smaller than the inner diameter of the locking ring 31 so that the rest of the control rod 2 can pass through the locking ring 31. When the control rod 2 slides along the sleeve away from the mop head, the control rod 2 can slide until the flange 22 abuts against the locking ring 31. Obviously, to facilitate the smooth installation of the control rod 2 into the sleeve of the connecting rod 3, that is, to ensure that the flange of the control rod 2 can pass smoothly through the position of the locking ring 31 during installation, the connecting rod 3 can be configured as a detachable connection between the sleeve 32 and the locking ring 31. When installation is required, the locking ring 31 is first separated from the sleeve 32, allowing the flange 22 of the control rod 2 to smoothly enter the sleeve 32, and then the locking ring 31 is connected to the sleeve 32. There are several ways to connect the locking ring 31 and the sleeve 32, such as using a threaded connection, where the locking ring 31 has an internal thread and the sleeve 32 has a matching external thread, or using a snap-fit ​​connection, etc.

[0037] Since the user operates the transmission unit 13 via the control lever 2 to move the clamping body 12 away from or towards the plate 11 only when it is necessary to assemble or disassemble the wiping object, and for most other occasions the control lever 2 needs to be in a position away from the mop head so that the control lever 2 is disengaged from the transmission unit 13 and avoids the connection between the connecting rod 3 and the mop head, thus preventing the control lever 2 from affecting the relative rotation of the connecting rod 3 and the mop head, some embodiments also include a first reset device 4. The first reset device 4 is used to move the control lever 2 away from the mop head or to keep the control lever 2 in a position away from the mop head. For example, the first reset device 4 can be a spring with its two ends abutting against the control lever 2 and the connecting rod 3, respectively. When the control lever 2 is driven to move towards the mop head, the spring is compressed to generate elastic force, maintaining the tendency to push the control lever 2 away from the mop head. In fact, when the spring is installed on the control rod 2 and the connecting rod 3, even if the control rod 2 is located far away from the mop head, the spring can be pre-compressed to a certain extent, thereby generating a preload force, so that the control rod 2 can be kept in a position far away from the mop head only under the action of the spring force when it is not driven by an external force.

[0038] In the above embodiment, when the first reset device 4 is a spring, it can be sleeved on the control rod 2, with its two ends abutting against the upper abutting surface 23 of the control rod 2 and the lower abutting surface 33 of the connecting rod 3, respectively. The upper abutting surface 23 and the lower abutting surface 33 are arranged opposite to each other. When the control rod 2 slides relative to the connecting rod 3, the upper abutting surface 23 and the lower abutting surface 33 move closer to each other or further away from each other to compress the spring or to relieve the spring force.

[0039] Since the control lever 2 needs to rotate relative to the plate 11 and the connecting rod 3 when it moves to a position close to the mop head, a washer can be set between the two ends of the spring and the upper abutment surface 23 and the lower abutment surface 33 respectively to prevent the spring from being twisted when the control lever 2 rotates, thus affecting its lifespan.

[0040] like Figure 7 In some embodiments, to facilitate user cleaning operations, it is necessary to prevent the control lever 2 from rotating relative to the plate 11 when it is away from the mop head, that is, to prevent the control lever 2 from rotating relative to the connecting rod 3. Therefore, an anti-rotation part 34 is provided on the connecting rod 3, and a locking part 24 is provided on the control lever 2. When the control lever 2 is located away from the mop head, that is, when the user needs to hold the control lever 2 or the connecting rod 3 to operate the wiping material for cleaning operations, the anti-rotation part 34 cooperates with the locking part 24 to restrict the relative rotation of the control lever 2 and the connecting rod 3. When the control lever 2 is located close to the mop head, that is, when the user needs to hold the control lever 2 to operate the transmission part 13 to rotate relative to the connecting rod 3 and the plate 11, the anti-rotation part 34 disengages from the locking part 24, so that the rotation of the control lever 2 relative to the connecting rod 3 is not affected by the anti-rotation part 34 and the locking part 24. For example, the anti-rotation part 34 can be a protrusion or groove on the inner wall of the sleeve away from the mop head, while the locking part 24 can be a groove or protrusion on the outer side of the control rod 2 near the mop head. When the control rod 2 is away from the mop head, the groove or protrusion on its outer side enters the protrusion or groove on the inner wall of the sleeve, thereby restricting the rotation of the control rod 2 relative to the connecting rod 3.

[0041] In the embodiments of this application, the control lever 2 can be located away from or near the mop head. When the control lever 2 is needed to operate the clamping body 12, the control lever 2 is connected to the transmission part 13 on the mop head. When the cleaning is needed normally using the wiping material at the bottom of the mop head, the reset device restricts the control lever 2 to a position away from the mop head, and the control lever 2 is disengaged from the transmission part 13. The end of the control member 2 near the mop head can avoid the rotational connection between the connecting rod 3 and the mop head, thereby preventing the control member 2 from affecting the relative rotation of the connecting rod 3 and the mop head. The structure is simple and avoids the complex structure used in the prior art to avoid the control member 2 affecting the relative rotation of the connecting rod 3 and the mop head.

[0042] This application discloses a cloth-clamping mop, such as... Figure 8 and Figure 9 As shown, the device includes a mop head and a cam 132. The mop head includes a plate 11 and a clamping body 12. The clamping body 12 is movably connected to the plate 11, for example, by sliding or rotating. Driven by the cam 132, it can move away from or closer to the plate 11 to clamp the wiping material on the bottom surface of the plate 11 or separate the wiping material from the bottom surface of the plate 11.

[0043] like Figure 11 and Figure 12 As shown, the cam 132 is provided with a drive groove 311. The cam 132 is rotatably mounted on the plate 11. The clamping body 12 is provided with a drive shaft 221. The drive groove 311 and the drive shaft 221 cooperate with each other. The drive shaft 221 can slide in the drive groove 311. When the drive shaft 221 moves to the first end of the drive groove 311, the clamping body 12 is located close to the plate 11, that is, in a clamping state, to clamp the wiping material. When the drive shaft 221 moves to the second end of the drive groove 311, the clamping body 12 is located away from the plate 11, that is, in a released state, to release the wiping material.

[0044] Furthermore, when the drive groove 311 rotates, the edge of its groove can push the drive shaft 221 to move, thereby causing the clamping body 12 to move closer to or away from the plate 11, thus clamping or releasing the wiping object. The implementation method is simple.

[0045] Generally, the first end of the drive groove 311 is closer to the rotation center of the cam 132 than the second end. That is, the first end of the drive groove 311 corresponds to the position where the radius of the cam 132 is the smallest, and the second end of the drive groove 311 corresponds to the position where the radius of the cam 132 is the largest. In some embodiments, the drive groove 311 includes an inner edge 3111 and an outer edge 3112. When the cam rotates in the first direction, the inner edge 3111 abuts against the drive shaft 221, thereby driving the drive shaft 221 to move from the first end of the drive groove 311 to the second end. That is, the clamping body 12 moves from a position close to the plate 11 to a position away from the plate 11, which is the process of releasing the wiping material. When the cam rotates in the second direction opposite to the first direction, the outer edge 3112 abuts against the drive shaft 221, thereby driving the drive shaft 221 to move from the second end of the drive groove 311 to the first end. That is, the clamping body 12 moves from a position away from the plate 11 to a position close to the plate 11, which is the process of clamping the wiping material. The drive groove 311 can be extended in a helical direction centered on the cam's rotation axis, which reduces the resistance when the drive shaft 221 slides with the drive groove 311 and satisfies the design requirement that the first end is closer to the cam's rotation center than the second end. This configuration is relatively simple to manufacture and assemble, requiring no other parts.

[0046] In some embodiments, a second reset device may be provided between the plate 11 and the clamping body 12. When the process of the clamping body 12 approaching the plate 11 is completed by the drive groove 311 driving the drive shaft 221 on the clamping body 12, the second reset device may have a tendency to drive the clamping body 12 away from the plate 11. Conversely, when the process of the clamping body 12 moving away from the plate 11 is completed by the drive groove 311 driving the drive shaft 221 on the clamping body 12, the second reset device may have a tendency to drive the clamping body 12 towards the plate 11. For example, the second reset device may be a spring such as a compression spring or a tension spring, or an energy storage device such as hydraulic or pneumatic pressure. When the second reset device is a spring, its two ends abut against the plate 11 and the clamping body 12 respectively, and extend along the direction in which the clamping body 12 approaches or moves away from the plate 11 in the direction of compression or stretching. When the clamping body 12 approaches the plate 11, the drive groove 311 drives the drive shaft 221 on the clamping body 12 to complete the process. During this process, the spring stores force, thus generating a tendency to push the clamping body 12 away from the plate 11. When the clamping body 12 moves away from the plate 11, the drive groove 311 drives the drive shaft 221 on the clamping body 12 to complete the process. During this process, the spring stores force, thus generating a tendency to push the clamping body 12 closer to the plate 11. The trend is as follows: during the process of the clamping body 12 moving closer to or away from the plate 11, one process is completed by the rotation of the cam, which in turn drives the drive shaft 221 via the drive groove 311. The other process is driven by the elastic force of the spring. For example, when the clamping body 12 moves away from the plate 11, it is completed by the drive shaft 221 on the clamping body 12 driven by the drive groove 311. Generally, in the initial state, the spring is kept in a free state or slightly compressed state. When the clamping body moves away from the plate 11, the wiping object can be released. At this time, the user only needs to place the bottom surface of the plate on the wiping object, and the clamping of the wiping object can be completed by the drive of the spring. The reverse is also true. This will not be elaborated here.

[0047] In some embodiments, such as Figure 11 and Figure 13As shown, the clamping body 12 is slidably connected to the plate body 11, that is, the clamping body 12 can slide relative to the plate body 11 to move closer to or away from the plate body 11. Specifically, the clamping body 12 is provided with a sliding groove 222, and the plate body 11 is provided with a sliding shaft 111. The sliding shaft 111 passes through the sliding groove 222 and can slide along the sliding groove 222. Similarly, the positions of the sliding groove 222 and the sliding shaft 111 can be interchanged to achieve the same effect as described above. However, regardless of whether the sliding groove 222 is set on the clamping body 12 or the plate 11, its extension direction is the same as the direction of approach or distance between the clamping body 12 and the plate 11, so that the clamping or releasing action of the clamping body 12 is not obstructed. Furthermore, the sliding fit between the sliding groove 222 and the sliding shaft 111 should be provided in at least two sets on the clamping body 12. The specific number can be appropriately increased according to the length of the clamping body 12. It is best to keep the sets symmetrical so that all parts of the clamping body 12 can move simultaneously without deflection, thus avoiding jamming or other situations.

[0048] In some embodiments, such as Figure 10 As shown, the plate 11 includes an upper cover plate 112 and a lower cover plate 113, which are interlocked to form a mounting cavity in the middle. The part of the clamping body 12 that slides with the plate 11 and the cam 132 are disposed in the mounting cavity, which protects these moving parts or parts thereof. At the same time, it also prevents foreign objects from falling into the position where these moving parts come into contact with each other, thereby hindering their movement or damaging these parts.

[0049] Furthermore, such as Figure 9 As shown, the clamping body 12 includes a main body 223 and a clamping part 224. Since the clamping part 224 generally requires a more complex structure to clamp the object being wiped, the main body 223 and the clamping part 224 are separately manufactured to facilitate the molding of the clamping body 12. During assembly, the two are detachably connected by means of snap-fit ​​or spring-loaded fasteners. Generally, the sliding groove on the clamping body 12 is provided on the main body 223. Part of the main body 223 is located between the upper cover plate 112 and the lower cover plate 113, and the rest extends out of the plate 11 and is detachably connected to the clamping part 224. The clamping part 224 is located on the side of the main body 223 facing the object being wiped. When the clamping body 12 needs to clamp the object being wiped, the distance between the clamping part 224 and the lower cover plate 113 is reduced, clamping the object being wiped between the clamping part 224 and the lower cover plate 113.

[0050] In some embodiments, the upper cover plate 112 is provided with a through hole 1121, through which the control rod 2 can pass and cooperate with the cam. Rotating the control rod 2 can drive the cam 132 to rotate, making it convenient for the user to operate the clamping body 12 to move closer to or away from the plate 11.

[0051] like Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides a cloth-clamping mop, including: a plate 11, on which a clamping body 12 is movably disposed, the clamping body 12 being movable relative to the plate 11, such that the clamping body 12 has a loose state with a clamping cavity between it and the plate 11 and a clamping state with it tightly abutting the plate 11; a transmission part 13, which is movably disposed on the plate 11 and is pulsatorically connected to the clamping body 12, for driving the clamping body 12 to move relative to the plate 11 so as to switch between the loose state and the clamping state; and a control component for controlling... The component is movably disposed relative to the plate 11, and the control component is movable relative to the plate 11, so that the control component has a contact state in which it is in transmission engagement with the transmission part 13 and a disengaged state in which it is out of contact with the transmission part 13; when the control component is in the contact state, it is driven to move the transmission part 13, and the movement of the transmission part 13 drives the clamping body 12 to move relative to the plate 11 so as to switch between the release state and the clamping state; when the control component is in the disengaged state, the control component is out of contact with the transmission part 13, so as to restrict the movement of the transmission part 13 under the drive of the control component.

[0052] For example, the clamping body 12 can be slidably connected to the plate 11 or rotated. When the clamping body 12 slides or rotates relative to the plate 11, the distance between the clamping body 12 and the plate 11 can be adjusted so that the clamping body 12 has a loose state with a clamping cavity between it and the plate 11 and a clamping state with it tightly abutting the plate 11.

[0053] The transmission unit 13 can be rotatably mounted on the plate 11 or slidably mounted on the plate 11. When the transmission unit 13 is driven to slide or rotate relative to the plate 11, it can drive the clamping body 12 to move, for example, drive the clamping body 12 to slide or rotate, so that the clamping body 12 switches between a released state and a clamping state. Optionally, the transmission unit 13 can be connected to the clamping body 12 through a gear set, or through a linkage assembly or lever assembly. When the transmission unit 13 is driven to slide or rotate relative to the plate 11, it can apply force to the clamping body 12 through the gear set, linkage assembly, or lever assembly, so that the clamping body 12 slides or rotates, and the clamping body 12 switches between a released state and a clamping state.

[0054] The control component can be slidably or rotatably disposed relative to the plate 11. Sliding or rotating the control component relative to the plate 11 adjusts the distance between the control component and the transmission part 13, allowing the control component to have a contact state where it is engaged with the transmission part 13 and a disengaged state where it is not engaged with the transmission part 13. Optionally, the control component can be movably disposed on the plate 11 or on the connecting rod 3 hinged to the plate 11. Taking the control component slidably disposed on the connecting rod 3 as an example, when the control component slides along the connecting rod 3 towards the plate 11 until it engages with the transmission part 13 on the plate 11, the control component is in a contact state. When the control component slides along the connecting rod 3 away from the plate 11 until it is disengaged from the transmission part 13 on the plate 11, the control component is in a disengaged state. When the control component is in the disengaged state, there is no transmission relationship between it and the transmission part 13. Therefore, even if there is relative movement between the control component and the plate 11 at this time, it cannot drive the transmission part 11 to move, and thus cannot cause the clamping body 12 to switch between the released state and the clamping state.

[0055] Optionally, the control component can be a rod, a sleeve, a knob, or a button. This utility model embodiment does not limit this. For ease of description, the following embodiment uses a rod as an example to illustrate the control component, that is, the control component can be a control lever.

[0056] This utility model discloses a cloth-clamping mop, which includes a control component. The control component has a contact state (engaged with a transmission unit) and a disengaged state (out of contact with the transmission unit). The control component can only drive the transmission unit to move when in the contact state, thereby switching the clamping body between a clamping and releasing state. When the control component is in the disengaged state, it cannot drive the transmission unit, thus preventing the clamping body from changing its state. In this way, the user can operate the control component during normal use of the cloth-clamping mop to disengage it. Even if the control component is accidentally activated, the clamping body will not move during use, preventing the cleaning material from being released, thus improving the user experience.

[0057] In one feasible embodiment, the cloth-clamping mop includes a connecting rod 3 connected to the plate 11, and a control rod 2 movably connected to the connecting rod 3; the control rod 2 is driven to move along the connecting rod 3 so that the control rod 2 switches between a contact state and a disengaged state.

[0058] For example, the connecting rod 3 can serve as a mop handle for easy gripping by the user, and the control rod 2 can be a sleeve that slides with the mop handle, or a rod body disposed in the hollow structure of the mop handle. Alternatively, the control rod 2 can serve as a mop handle for easy gripping by the user, and the connecting rod 3 can be a sleeve that slides with the mop handle, or a rod body disposed parallel to the mop handle.

[0059] In one feasible embodiment, the control rod 2 is slidably connected to the connecting rod 3; the control rod 2 is driven to slide along the connecting rod 3, thereby switching the control rod 2 between a contact state and a disengaged state. Optionally, the connecting rod 3 is a hollow sleeve 32, the end of which is rotatably connected to the plate 11, and the control rod 2 is slidably inserted through the hollow region of the sleeve 32; the control rod 2 is driven to slide within the hollow region of the sleeve 32, thereby switching the control rod 2 between a contact state and a disengaged state. For example, the control lever 2 passes through the transmission part 13, such that the two ends of the control lever 2 are located on both sides of the transmission part 13. The control lever 2 is driven to slide in the hollow area of ​​the sleeve 32, such that one end of the control lever 2 moves away from the plate 11, and the other end moves from the side of the transmission part 13 away from the connecting rod 3 towards the transmission part 13, until the other end engages with the transmission part 13, at which point the control lever 2 is in contact. The control lever 2 is driven to slide in the hollow area of ​​the sleeve 32, such that one end of the control lever 2 moves towards the plate 11, and the other end moves away from the transmission part 13 from the side of the transmission part 13 away from the connecting rod 3, until the other end disengages from the transmission part 13, at which point the control lever 2 is in disengagement.

[0060] For example, the control lever 2 can also be located entirely on the side of the transmission part 13 near the connecting rod 3. In this case, the control lever 2 is driven to slide towards the plate 11 in the hollow area of ​​the sleeve 32 until the control lever 2 is in contact with the transmission part 13 movably provided on the plate 11. When the control lever 2 is driven to slide away from the plate 11 in the hollow area of ​​the sleeve 32 until the control lever 2 is disengaged from the transmission part 13 movably provided on the plate 11, the control lever 2 is in disengaged state.

[0061] For example, a first reset device 4 is provided between the control lever 2 and the connecting rod 3; when the control lever 2 is driven to slide towards the plate 11 until it engages with the transmission part 13, the control lever 2 is in a contact state, and the first reset device 4 stores force; when the first reset device 4 releases force, it causes the control lever 2 to slide away from the plate 11 until it disengages from the transmission part 13, and the control lever 2 is in a disengaged state. Optionally, the first reset device 4 can be a spring, an air pump, or a spring sheet, etc.

[0062] In one feasible embodiment, when the control lever 2 is in the contact state, the driven relative to the connecting rod 3 rotates, causing the transmission part 13 to move; when the control lever 2 is driven to move along the connecting rod 3 to switch from the contact state to the disengagement state, the connecting rod 3 and the control lever 2 are engaged in a circumferential anti-rotation engagement.

[0063] For example, the control rod 2 is coaxially inserted into the hollow structure of the connecting rod 3. When the control rod 2 is in the contact state, it is driven to rotate about the central axis of the connecting rod 3 within the hollow structure. At this time, the control rod 2 can drive the transmission part 13 to rotate coaxially, thereby causing the clamping body 12 to switch between the clamping state and the releasing state. When the control rod 2 is driven to slide away from the plate 11 along the axial direction of the connecting rod 3 until it disengages from the transmission part 13, the control rod 2 and the connecting rod 3 are circumferentially limited, i.e., circumferentially anti-rotation, so that the control rod 2 cannot rotate relative to the connecting rod 3. This setting is to avoid the situation where the user cannot control the cleaning direction due to the relative rotation of the control rod 2 and the connecting rod 3 under force when using the cloth-clamping mop.

[0064] In one feasible embodiment, the connecting rod 3 is provided with an anti-rotation part 34, and the control rod 2 is provided with a locking part 24. When the control rod 2 is driven to move along the connecting rod 3 to the disengaged state, it drives the locking part 24 to move to cooperate with the anti-rotation part 34 to restrict the relative rotation between the control rod 2 and the connecting rod 3. When the control rod 2 is driven to move along the connecting rod 3 from the disengaged state to the contact state, it drives the locking part 24 to move to disengage from the anti-rotation part 34, so that the control rod 2 can rotate relative to the connecting rod 3 to drive the transmission part 13 to move.

[0065] Optionally, the connecting rod 3 is a sleeve 32 fitted onto the control rod 2, the anti-rotation part 34 is a protrusion or groove provided on the inner wall of the sleeve 32, and the locking part 24 is a groove or protrusion provided on the outer wall of the control rod 2. When the protrusion is inserted into the groove, the sleeve 32 and the control rod 2 are in a circumferential anti-rotation fit; when the protrusion is disengaged from the groove, the sleeve 32 and the control rod 2 can rotate relative to each other.

[0066] In one feasible embodiment, a limiting structure is provided between the connecting rod 3 and the control rod 2; the limiting structure is used to restrict the relative movement between the connecting rod 3 and the control rod 2 when locked, and to release the restriction on the connecting rod 3 and / or the control rod 2 when unlocked, so that the control rod 2 can be driven to move along the connecting rod 3 to switch between a contact state and a disengaged state.

[0067] In this way, when control lever 2 is in the disengaged state, the limiting structure locks control lever 2, preventing the user from being unable to apply force to the surface to be cleaned due to relative movement between control lever 2 and connecting rod 3 when using the cloth-clamping mop. When the user needs to change the wiping material, the limiting structure unlocks control lever 2 and connecting rod 3, allowing control lever 2 to switch between contact and disengagement states relative to connecting rod 3.

[0068] In one feasible embodiment, the connecting rod 3 is a hollow sleeve 32 hinged to the plate 11, and the control rod 2 slides through the hollow area of ​​the sleeve 32. The limiting structure includes a locking ring 31 disposed at the end of the connecting rod 3 away from the plate 11. The locking ring 31 is connected to the sleeve 32 by threads. When the locking ring 31 rotates around the connecting rod 3 by threads until the sleeve 32 and the control rod 2 are in close contact, the locking ring 31 locks the sleeve 32 and the control rod 2 to restrict the relative movement between the sleeve 32 and the control rod 2. When the locking ring 31 rotates around the connecting rod 3 by threads until the sleeve 32 and the control rod 2 are in clearance fit, the locking ring 31 unlocks the sleeve 32 and the control rod 2, so that the control rod 2 is driven to slide along the hollow area of ​​the sleeve 32 to switch between the contact state and the disengagement state.

[0069] In one feasible embodiment, a locking ring 31 is provided at the end of the sleeve 32 away from the plate 11, and a flange 22 is provided on the control rod 2. When the control rod 2 is driven to slide away from the plate 11 in the hollow region of the sleeve 32 to the maximum displacement, the flange 22 abuts against the locking ring 31 to prevent the control rod 2 from disengaging from the sleeve 32.

[0070] In one feasible embodiment, when the control lever 2 is in the contact state, the limiting part 21 on the control lever 2 abuts against the mating part 131 on the transmission part 13, so that the control lever 2 and the transmission part 13 are circumferentially limited and fitted, thereby causing the control lever 2 to rotate and drive the transmission part 13 to rotate.

[0071] For example, one of the limiting part 21 and the mating part 131 is provided with a protrusion, and the other is provided with a groove; when the control rod 2 moves relative to the plate 11 to the contact state, the protrusion is inserted into the groove so that the control rod 2 and the transmission part 13 achieve circumferential limiting mating.

[0072] Optionally, the groove can be a cross groove, a T-groove, or a rectangular groove, and the protrusion can be a cross-shaped protrusion, a T-shaped protrusion, or a rectangular protrusion that mates with the groove.

[0073] In one feasible embodiment, the control lever 2 includes a first lever body 25 and a second lever body 26. When the control lever 2 is in a contact state, the second lever body 26 is in a transmission engagement with the transmission part 13, and the first lever body 25 is in a transmission connection with the second lever body 26. The first lever body 25 is driven to move towards or away from the plate 11, which drives the second lever body 26 to rotate. The rotation of the second lever body 26 drives the transmission part 13 to move.

[0074] For example, the first rod 25 and the second rod 26 can be connected by a twisted rod. When the first rod 25 moves axially, it drives the second rod 26 to rotate via the twisted rod. For instance, when a user places the plate 11 on the bottom surface and then presses down on the first rod 25 for gripping, the first rod 25 causes the slider to slide on the twisted rod, which is coaxially fixed with the second rod 26. Rotation of the twisted rod will drive the second rod 26 to rotate.

[0075] For example, a connecting rod 3 is hinged to the plate 11, and a second rod 26 is disposed in the hollow region of the connecting rod 3, and the second rod 26 is rotatable relative to the connecting rod 3. The end of the first rod 25 extends into the hollow region of the connecting rod 3 and is connected to the second rod 26 in a transmission manner.

[0076] Optional, see reference Figure 14 As shown, the second rod 26 has a guide spiral surface 261 at one end near the first rod 25. When the control rod 2 is in the contact state, the end 251 of the first rod 25 abuts against the guide spiral surface 261. The first rod 25 is driven to move closer to the plate 11, that is... Figure 14 In the X direction, when the user places the plate 11 on the bottom surface and then presses down on the first rod 25 for gripping, the end 251 of the first rod 25 pushes against the second rod 26 along the guide spiral surface 261. The end 251 of the first rod 25 slides along the guide spiral surface 261 from the end away from the plate 11 to the end closer to the plate 11. Since the first rod 25 is circumferentially immovable, in order to counteract the force applied by the end 251 of the first rod 25, the second rod 26 can rotate under the action of the guide spiral surface 261. Figure 14 Rotate in the Y direction.

[0077] Optional, see reference Figure 14 As shown, the second rod 26 has multiple guide spiral surfaces connected end-to-end at one end near the first rod 25. When the control rod 2 is in the contact state, the end of the first rod 25 abuts against one of the guide spiral surfaces. When the control rod 2 is driven to move relative to the plate 11 from the contact state to the disengagement state, the end of the first rod 25 moves away from the second rod 26 until it disengages from the guide spiral surface. When the control rod 2 is driven to move relative to the plate 11 again from the disengagement state to the contact state, the end of the first rod 25 moves towards the second rod 26 until it abuts against another guide spiral surface adjacent to the guide spiral surface. This allows the user to press down on the first rod 25 again when the control rod 2 is in the contact state, causing the second rod 26 to rotate. In practical applications, the end 251 of the first rod 25 can also be provided with multiple spiral surfaces that fit with the guide spiral surface. The pushing action of the two spiral surfaces can improve the stability of the rotation between the first rod 25 and the second rod 26.

[0078] In one feasible embodiment, the first rod 25 has a hollow structure, and the end of the second rod 26 away from the plate 11 extends into the hollow structure; as Figure 15 As shown, the inner wall of the hollow structure of the first rod 25 is provided with an axial groove 252 extending along the axial direction of the first rod 25 and a guide spiral groove 253 communicating with the axial groove 252; the end of the second rod 26 away from the plate 11 is provided with a shaft 262 that cooperates with the axial groove 252 and the guide spiral groove 253; the first rod 25 is driven to move towards the plate 11 ( Figure 15 When the user places the plate 11 on the bottom surface and presses down on the first lever 25 for gripping, the shaft 262 of the second lever 26 slides along the axial groove 252 and from the end of the axial groove 252 near the plate 11 to the end away from the plate 11 (actually, the axial groove 252 slides relative to the shaft 262, and the shaft 262 remains stationary in the axial direction of the control lever 2). At this time, the second lever 26 does not rotate. After the shaft 262 slides from the end of the axial groove 252 near the plate 11 to the end away from the plate 11, if the first lever 25 is driven to move away from the plate 11, the shaft 262 passes over the end of the axial groove 252 near the plate 11 and slides to the end away from the plate 11, entering the guide spiral groove 253 and sliding along the guide spiral groove 253. At this time, the shaft 262 can slide from the end of the guide spiral groove 253 away from the plate 11 to the end near the plate 11. Since the first rod 25 is immovable in the circumferential direction, the second rod 26 rotates (along the guide spiral groove 253) under the pushing action of the guide spiral groove 253. Figure 15 (Rotation in the Y direction).

[0079] Example, reference Figure 15As shown, the inner wall of the hollow structure is provided with multiple axial grooves 252 and multiple guide spiral grooves 253, and the two ends of any one guide spiral groove 253 are respectively connected to two axial grooves 252. The end of the first axial groove 252 away from the plate 11 is connected to the guide spiral groove 253, and the end of the second axial groove 252 near the plate 11 is connected to the guide spiral groove 253. When the control rod 2 is in the contact state, the shaft 262 is at the end of the first axial groove near the plate 11. When the first rod 25 is driven to move towards the plate 11, the shaft... The shaft 262 slides along the first axial groove 252 to the end of the first axial groove 252 away from the plate 11 and enters the end of the guide spiral groove 253. When the first rod 25 is driven to move away from the plate 11, the shaft 262 slides along the guide spiral groove 253 and drives the second rod 26 to rotate until the shaft 262 slides to the end of the guide spiral groove 253 close to the plate 11 and enters the end of the second axial groove 252 close to the plate 11, so that when the first rod 25 is driven to move closer to the plate 11 again, the shaft 262 slides along the second axial groove 252.

[0080] In one feasible embodiment, an elastic element can be provided between the first rod 25 and the second rod 26; when the control rod 2 is in the contact state, the first rod 25 is driven to move towards the plate 11, and the elastic element 27 is compressed and stores force; the elastic element 27 releases force, causing the first rod 25 to move away from the second rod 26. Therefore, when the control rod 2 is in the contact state, the elastic element can act as a reset element, used to reset the first rod 25.

[0081] In one feasible embodiment, when the control lever 2 is in the disengaged state, the first lever 25 is driven to move towards the plate 11, pushing against the elastic element. The elastic element then pushes against the second lever 26, causing it to move towards the plate 11, until the second lever 26 engages with the transmission unit 13 and the control lever 2 is in contact. Therefore, when the control lever 2 is in the disengaged state, the elastic element can act as a force-applying element, transmitting the force of the first lever 25 to the second lever 26, so that the first lever 25 can drive the second lever 26 to move towards the plate 11.

[0082] Optionally, the elastic element can be a spring, a sheet, a pneumatic pump, or a flexible element with deformation and reset functions.

[0083] In one feasible embodiment, the transmission part 13 is rotatably disposed on the plate 11. When the control lever 2 is in the contact state, it is driven to rotate the transmission part 13. The rotation of the transmission part 13 causes the clamping body 12 to move relative to the plate 11 so as to switch between the released state and the clamping state.

[0084] For example, such as Figure 2 , Figure 3 Figure 13 As shown, the transmission unit 13 can be a cam 132 rotatably mounted on the plate 11, and the clamping body 12 is slidably connected to the cam 132. The control lever 2 is driven to rotate the cam, and the clamping body 12 slides relative to the cam 132. When the clamping body 12 slides relative to the cam 132 to the position where the radius of the cam 132 is the smallest, the clamping body 12 is in a clamping state; when the clamping body 12 slides relative to the cam 132 to the position where the radius of the cam 132 is the largest, the clamping body 12 is in a released state. Optionally, the clamping body 12 can abut against the edge of the cam 132 and slide along the edge contour of the cam 132. When the control lever 2 drives the cam 132 to rotate, the clamping body 12 slides along the edge contour of the cam 132 to the position where the radius of the cam 132 is the smallest. At this point, the distance between the clamping body 12 and the rotation center of the cam 132 is the shortest, that is, the clamping body 12 is closest to the plate 11 and the distance between them is the smallest. The clamping body 12 is in a clamping state. When the clamping body 12 slides along the edge contour of the cam 132 to the position where the radius of the cam 132 is the largest, the distance between the clamping body 12 and the rotation center of the cam 132 is the largest, that is, the clamping body 12 is closest to the plate 11 and the distance between them is the largest. The clamping body 12 is in a released state.

[0085] Optional, such as Figure 13 As shown, a drive groove 311 is provided on the cam 132. The drive groove 311 extends along the outer contour of the cam 132, meaning that the drive groove 311 has an area corresponding to the position with the smallest radius of the cam 132 and an area corresponding to the position with the largest radius of the cam 132. A drive shaft 221 is provided on the clamping body 12 and is inserted into the drive groove 311. When the control lever 2 is driven, the cam 132 rotates, and the drive shaft 221 slides along the drive groove 311. When the drive shaft 221 slides to the end of the drive groove 311 corresponding to the position with the smallest radius of the cam 132, the clamping body 12 is in a clamping state. When the drive shaft 221 slides to the end of the drive groove 311 corresponding to the position with the largest radius of the cam 132, the clamping body 12 is in a released state.

[0086] Optional, such as Figure 3 and Figure 13As shown, the cam 132 includes a first semicircular portion 1321 and a second semicircular portion 1322. The diameter side of the first semicircular portion 1321 and the diameter side of the second semicircular portion 1322 partially overlap, and the center of the overlapping area is the rotation axis of the cam 132. Both the first semicircular portion 1321 and the second semicircular portion 1322 are provided with drive grooves 311, and both drive grooves 311 extend according to the contour of the arc side of the semicircular portion. Clamping bodies 12 are movably provided on opposite sides of the plate 11, and the drive shafts 221 of the two clamping bodies 12 are respectively inserted into the drive grooves 311 on the two semicircular portions. The control lever 2 drives the cam 132 to rotate, and the two drive shafts 221 slide along the two drive grooves 311 respectively, so that the two clamping bodies 12 move simultaneously toward or away from the plate 11.

[0087] In one feasible embodiment, such as Figure 10 and Figure 13 As shown, the plate 11 includes an upper cover plate 112 and a lower cover plate 113 that are interlocked. A cam 132 is rotatably disposed on either the upper cover plate 112 or the lower cover plate 113, and is located between the upper cover plate 112 and the lower cover plate 113. The upper cover plate 112 is provided with a through hole 1121. When the control rod 2 moves relative to the plate 11 until it passes through the through hole 1121 and engages with the transmission part 13, it is in a contact state. When the control rod 2 moves relative to the plate 11 until it moves out of the through hole 1121 and disengages from the transmission part 13, it is in a disengaged state.

[0088] For example, a connecting rod 3 is hinged to the plate 11, and a through hole 1121 can be provided directly below the connecting rod 3. A control rod 2 is provided in the hollow structure of the connecting rod 3 and can slide relative to the connecting rod 3 along the axial direction of the connecting rod 3. When the control rod 2 is driven to move along the axial direction of the connecting rod 3 towards the plate 11 until it extends out of the hollow structure of the connecting rod 3 and into the through hole 1121 on the upper cover plate 112, and is in contact with the transmission part 13 provided between the upper cover plate 112 and the lower cover plate 113, the control rod 2 is in a contact state. When the control rod 2 is driven to move along the axial direction of the connecting rod 3 away from the plate 11 until its end moves out of the plate 11 from the through hole 1121 of the upper cover plate 112 and disengages from the transmission part 13, the control rod 2 switches to a disengaged state.

[0089] Optional, such as Figure 13As shown, the clamping body 21 is slidably connected to the upper cover plate 112 or the lower cover plate 113; the control rod 2 is driven to rotate the cam 132. When the clamping body 12 slides relative to the cam 132, it slides relative to the upper cover plate 112 or the lower cover plate 113. When the clamping body 12 slides relative to the cam 132 to the position where the radius of the cam 132 is the smallest, the clamping body 12 slides relative to the upper cover plate 112 or the lower cover plate 113 to the clamping state where it is in close contact with the upper cover plate 112 or the lower cover plate 113; when the clamping body 12 slides relative to the cam 132 to the position where the radius of the cam 132 is the largest, the clamping body 12 slides relative to the upper cover plate 112 or the lower cover plate 113 to the loosened state where there is a clamping cavity between it and the upper cover plate 112 or the lower cover plate 113.

[0090] like Figure 10 , Figure 12 and Figure 13 As shown, this utility model embodiment also provides a cloth-clamping mop, including: a plate 11, on which a clamping body 12 is movably disposed, the clamping body 12 being movable relative to the plate 11, such that the clamping body 12 has a loose state with a clamping cavity between it and the plate 11 and a clamping state with it tightly abutting against the plate 11; a cam 132, rotatably disposed on the plate 11, and provided with a drive groove 311, the drive groove 311 extending along the outer contour of the cam 132; a drive shaft 221 disposed on the clamping body 12, the drive shaft 221 being inserted into the drive groove 311; the cam 132 is driven to rotate, and the drive shaft 221 slides along the drive groove 311; when the drive shaft 221 slides to the end of the drive groove 311 corresponding to the position with the smallest radius of the cam 132, the clamping body 12 is in a clamping state; when the drive shaft 221 slides to the end of the drive groove 311 corresponding to the position with the largest radius of the cam 132, the clamping body 12 is in a loose state.

[0091] In this way, the cam 132 drives the clamping body 12 to move relative to the plate 11 through the drive groove 311, which improves the stability of the clamping body 12's movement and avoids the clamping body 12 from disengaging from the cam 132 during the movement, thus preventing the clamping body 12 from being driven.

[0092] Optional, such as Figure 3 and Figure 13As shown, the cam 132 includes a first semicircular portion 1321 and a second semicircular portion 1322. The diameter side of the first semicircular portion 1321 and the diameter side of the second semicircular portion 1322 partially overlap, and the center of the overlapping area is the rotation axis of the cam 132. Both the first semicircular portion 1321 and the second semicircular portion 1322 are provided with drive grooves 311, and both drive grooves 311 extend according to the contour of the arc side of the semicircular portion. Clamping bodies 12 are movably provided on opposite sides of the plate 11. The drive shafts 221 of the two clamping bodies 12 are respectively inserted into the drive grooves 311 on the two semicircular portions. When the cam 132 is driven to rotate, the two drive shafts 221 slide along the two drive grooves 311, so that the two clamping bodies 12 move simultaneously toward or away from the plate 11.

[0093] Optional, such as Figure 10 and Figure 13 As shown, the plate 11 includes an upper cover plate 112 and a lower cover plate 113 that are interlocked with each other. The cam 132 is rotatably disposed on the upper cover plate 112 or the lower cover plate 113 and is located between the upper cover plate 112 and the lower cover plate 113.

[0094] like Figure 10 and Figure 12 As shown, the upper cover plate 112 has a through hole 1121. The control component passes through the through hole 1121 and engages with the cam 132 in a transmission relationship. The control component is driven to rotate, which in turn drives the cam 132 to rotate. This control component can be a control lever 2.

[0095] Optional, such as Figure 13 As shown, the clamping body 21 is slidably connected to the upper cover plate 112 or the lower cover plate 113; the control component is driven to rotate, causing the cam 132 to rotate. When the clamping body 12 slides relative to the cam 132, it slides relative to the upper cover plate 112 or the lower cover plate 113. When the clamping body 12 slides relative to the cam 132 to the position where the radius of the cam 132 is the smallest, the clamping body 12 slides relative to the upper cover plate 112 or the lower cover plate 113 to the clamping state where it is in close contact with the upper cover plate 112 or the lower cover plate 113; when the clamping body 12 slides relative to the cam 132 to the position where the radius of the cam 132 is the largest, the clamping body 12 slides relative to the upper cover plate 112 or the lower cover plate 113 to the loosened state where there is a clamping cavity between it and the upper cover plate 112 or the lower cover plate 113.

[0096] In one feasible embodiment, such as Figure 13 As shown, a second reset device is provided between the plate 11 and the clamping body 12; when the clamping body 12 is in the clamping state, the second reset device has the tendency to drive the clamping body 12 away from the plate 21; or, when the clamping body 12 is in the released state, the second reset device has the tendency to drive the clamping body 12 closer to the plate 21.

[0097] In one feasible embodiment, the second reset device is a spring, with its two ends abutting against the plate 21 and the clamping body 12, respectively. When the clamping body 12 is in the clamping state, the spring stores force to apply a force away from the plate 21 to the clamping body 12; or, when the clamping body 12 is in the released state, the spring stores force to apply a force close to the plate 21 to the clamping body 12.

[0098] This utility model embodiment also provides a cloth-clamping mop, such as Figure 10 , Figure 12 and Figure 13 As shown, it includes: a plate 11, which includes an upper cover plate 112 and a lower cover plate 113, forming a mounting cavity between the upper cover plate 112 and the lower cover plate 113; a clamping body 12, one end of which extends into the mounting cavity and is movably connected to the upper cover plate 112 or the lower cover plate 113, and has a loose state with a clamping cavity between it and the plate 11 and a clamping state with it tightly abutting against the plate 11; and a transmission part 13, which is located in the mounting cavity and rotatably disposed on the upper cover plate 112 or the lower cover plate 113, and the rotation axis of the transmission part 13 is perpendicular to the upper cover plate 112 or the lower cover plate 113. The transmission part 13 is connected to the clamping body 12 via the upper cover plate 112 or the lower cover plate 113, and is used to drive the clamping body 12 to move relative to the plate 11 so as to switch between the loose state and the clamping state. The control part is movably disposed with the plate 11. The upper cover plate 112 is provided with a through hole 1121. The control part passes through the through hole 1121 and is in transmission cooperation with the transmission part 13. The control part is driven to move relative to the plate, which drives the transmission part 13 to move. The movement of the transmission part 13 drives the clamping body 12 to move so as to switch between the loose state and the clamping state.

[0099] Optionally, the transmission unit 13 is rotatably mounted on the upper cover plate 112 or the lower cover plate 113. The control component is driven to move relative to the plate body, causing the transmission unit 13 to rotate. The rotation of the transmission unit 13 causes the clamping body 12 to move to switch between a released state and a clamping state. The transmission unit 13 can be a cam 132 rotatably mounted on the upper cover plate 112 or the lower cover plate 113. The rotation shaft of the cam 132 is vertically mounted on the upper cover plate 112 or the lower cover plate 113, and the cam 132 is sleeved on the rotation shaft.

[0100] Optionally, the clamping body 12 is slidably connected to the edge contour of the cam 132 or the drive groove 311 provided on the cam 132. When the control component is driven to move relative to the plate and drive the cam 132 to rotate, the clamping body 12 slides along the edge contour of the cam 132 or the drive groove 311 provided on the cam 132, so that the clamping body 12 switches between the released state and the clamping state.

[0101] In one feasible embodiment, a control element is movably disposed on the upper cover plate 112. The control element is driven to move relative to the upper cover plate 112, thereby driving the transmission part 13 to move. The movement of the transmission part 13 drives the clamping body 12 to move to switch between a released state and a clamping state.

[0102] For example, the transmission unit 13 can be a cam 132. The control member can be slidably disposed on the upper cover plate 112, rotatably disposed on the upper cover plate 112, or oscillatingly disposed on the upper cover plate 112. When the control member is driven to slide, rotate, or oscillate relative to the upper cover plate 112, it drives the cam 132 to rotate. The rotation of the cam 132 can drive the clamping body 12 to move to switch between the released state and the clamping state.

[0103] In one feasible embodiment, such as Figure 16 and Figure 17 As shown, the control component can be a knob 6, which is rotatably mounted on the upper cover plate 112. The through hole 1121 on the upper cover plate 112 is an arc-shaped slot. A connecting post 61 is provided on the side of the knob 6 near the transmission part 13. The connecting post 61 passes through the arc-shaped slot and connects to the transmission part 13. When the knob 6 is driven to rotate relative to the upper cover plate 112, the connecting post 61 slides along the arc-shaped slot. For example, when the knob 6 is driven to rotate forward relative to the upper cover plate 112, the connecting post slides from one end of the arc-shaped slot to the other end, and drives the cam 132 to rotate forward, so that the clamping body 12 switches from the loose state to the clamping state. When the knob 6 is driven to rotate in the opposite direction relative to the upper cover plate 112, the connecting post slides from the other end of the arc-shaped slot to the other end, and drives the cam 132 to rotate in the opposite direction, so that the clamping body 12 switches from the clamping state to the loose state.

[0104] For example, the connecting post 61 passes through the arc-shaped hole and is fixedly connected to the cam 132. The cam 132 can be composed of the two semicircular parts mentioned above, or it can be an elliptical cam 132. When the knob 6 is driven to rotate relative to the upper cover plate 112, the connecting post 61 drives the cam 132 to rotate, and at the same time slides through the arc-shaped hole on the upper cover plate 112. In practical applications, the through hole 1121 can also be an annular groove with the same contour as the cam 132, so that when the knob 6 is driven to continuously move in one direction, the connecting post 61 can interact in the annular groove and drive the cam 132 to continuously rotate. In this way, even if the knob 6 can only rotate in one direction, the clamping body can switch between the released state and the clamping state.

[0105] In one feasible embodiment, the cloth-clamping mop further includes a mop handle, the end of which is hinged to the upper cover plate 112, and a control element is disposed around the end of the mop handle. Figure 17As shown, the control element can be a knob 6 positioned around the end of the mop handle. Optionally, the mop handle held by the user can be a control lever 2 or a connecting lever 3. The knob 6 is annular, surrounding the end of the mop handle and protruding from the surface of the upper cover plate 112. The user can rotate this annular knob 6 to drive the cam 132 to rotate.

[0106] This utility model provides a cloth-clamping mop, such as Figure 1 , Figure 14 and Figure 15 As shown, the cloth-clamping mop includes: a plate 11, on which a clamping body 12 is movably disposed, the clamping body 12 being movable relative to the plate 11, such that the clamping body 12 has a loose state with a clamping cavity between it and the plate 11 and a clamping state with it tightly abutting the plate 11; a transmission part 13, which is movably disposed on the plate 11 and is pulsatorically connected to the clamping body 12, for driving the clamping body 12 to move relative to the plate 11 to facilitate switching between the loose state and the clamping state; and a control component, which is connected to the plate 11. The plate 11 is relatively movable, and the control component is connected to the transmission part 13. When the control component is driven to move relative to the plate 11 for the first time, it drives the transmission part 13 to move. The movement of the transmission part 13 drives the clamping body 12 to move relative to the plate 11 so that the clamping body 12 can switch from the loose state to the clamping state. When the control component is driven to move relative to the plate 11 for the second time, it drives the transmission part 13 to move. The movement of the transmission part 13 drives the clamping body 12 to move relative to the plate 11 so that the clamping body 12 can switch from the clamping state to the loose state.

[0107] For example, in this embodiment, the first and second activities are performed in the same way. For instance, if the activity is defined as the control component being driven to move closer to the plate 11, then the first movement of the control component towards the plate 11 is the first activity, and the second movement is the second activity. If the activity is defined as the control component being driven to move closer to the plate 11 and then resetting, then the first movement of the control component towards the plate 11 and then resetting is the first activity, and the second movement is the second activity.

[0108] Alternatively, if the controlled component rotates clockwise relative to the plate 11 by a preset angle, such as 45 degrees, as the activity, then the first 45-degree clockwise rotation of the controlled component relative to the plate 11 is the first activity, and the second 45-degree clockwise rotation is the second activity. If the controlled component rotates clockwise relative to the plate 11 by a preset angle and then resets, such as 45 degrees, as the activity, then the first 45-degree clockwise rotation and reset of the controlled component relative to the plate 11 is the first activity, and the second 45-degree clockwise rotation and reset is the second activity.

[0109] In existing technologies, the operation methods of clamping and releasing the wiping material in a cloth-clamping mop, driven by a control component, are different. Specifically, the control component needs to move the clamping body in a first manner to switch from a released state to a clamping state to hold the wiping material; and in a second manner to switch the clamping body from a clamping state to a released state to release the wiping material. For example, the control component can be a slider on the mop handle. When the slider slides along the mop handle axis towards the plate 11, it drives the clamping body to switch from a released state to a clamping state; when the slider slides along the mop handle axis away from the plate 11, it drives the clamping body to switch from a clamping state to a released state. In other words, the user needs to distinguish between two opposite operations to achieve the clamping and releasing of the wiping material. The control component of the cloth-clamping mop disclosed in this utility model has only one mode of operation, meaning that the operation of the control component is simple. Users can repeatedly operate the control component to clamp or release the cloth-clamping mop. That is, the first operation of the control component switches the clamping body from the loose state to the clamping state, and the second operation switches the clamping body from the clamping state to the loose state. Users do not need to distinguish between clamping and releasing the cloth-clamping mop, making the operation simple and providing a better user experience.

[0110] In one feasible embodiment, the control member is driven to move relative to the plate 11 for the first time, which drives the transmission part 13 to move. The movement of the transmission part 13 drives the clamping body 12 to move relative to the plate 11, so that the clamping body 12 switches from the loose state to the clamping state and is positioned in the clamping state. The control member is driven to move relative to the plate 11 for the second time, which drives the transmission part 13 to move. The movement of the transmission part 13 drives the clamping body 12 to move relative to the plate 11, so that the clamping body 12 switches from the clamping state to the loose state and is positioned in the loose state.

[0111] For example, when the transmission unit 13 drives the clamping body 12 to switch from the released state to the clamping state, it can position the clamping body 11 so that the clamping body 11 is kept in the clamping state, which makes it convenient for the user to lay the wiping material or move the plate 11 above the wiping material to clamp the wiping material, so as to avoid the situation where the wiping material is not firmly clamped due to uneven laying of the wiping material or misalignment of the plate 11 with the wiping material.

[0112] Similarly, when the transmission unit 13 drives the clamping body 12 to switch from the clamping state to the releasing state, it can position the clamping body 11 so that the clamping body 11 remains in the releasing state, making it easier for the user to easily remove the wiping material from the plate 11, and avoiding the situation where the wiping material is clamped again due to the user's inability to operate quickly.

[0113] In one feasible embodiment, the transmission part 13 is rotatably disposed on the plate 11; the control member is driven to move relative to the plate 11 for the first time, driving the transmission part 13 to rotate, and the rotation of the transmission part 13 drives the clamping body 12 to move relative to the plate 11, so that the clamping body 12 switches from the loose state to the clamping state and is positioned in the clamping state; the control member is driven to move relative to the plate 11 for the second time, driving the transmission part 13 to rotate, and the rotation of the transmission part 13 drives the clamping body 12 to move relative to the plate 11, so that the clamping body 12 switches from the clamping state to the loose state and is positioned in the loose state.

[0114] For example, the rotation direction of the transmission part 13 when the control member moves relative to the plate 11 for the first time can be the same as or opposite to the rotation direction of the transmission part 13 when the control member moves relative to the plate 11 for the second time. That is, in this embodiment, the movement mode of the transmission part 13 during the two movements of the control member is not limited.

[0115] In one feasible embodiment, such as Figure 18 As shown, the transmission part 13 includes a cam 132 rotatably disposed on the plate 11, and the clamping body 12 is slidably connected to the cam 132. The cam 132 includes at least two base positions with the smallest radius and two protruding positions with the largest radius, and the base positions and protruding positions are staggered. When the clamping body 12 slides relative to the cam 132 to the base position, it is in a clamping state, and when the clamping body 12 slides relative to the cam 132 to the protruding position, it is in a releasing state. The control component moves relative to the plate 11 for the first time, causing the cam 132 to rotate. The clamping body 12 slides relative to the cam 132, and slides from the first protruding position to the first basic position and is positioned at the first basic position, so that the clamping body 12 switches from the loose state to the clamping state and is positioned at the clamping state. The control component moves relative to the plate 11 for the second time, causing the cam 132 to rotate. The clamping body 12 continues to slide relative to the cam 132, and slides from the first basic position to the second protruding position and is positioned at the second protruding position, so that the clamping body 12 switches from the clamping state to the loose state and is positioned at the loose state.

[0116] For example, since the base position and the protruding position on the cam 132 are staggered, the clamping body 12 can slide to the base position and the protruding position in sequence when sliding along the cam 132, so that the clamping body 12 can cycle from the loose state to the clamping state and from the clamping state to the loose state, and the structure of the plate 11 is relatively simple.

[0117] In one feasible embodiment, such as Figure 19As shown, the cam 132 is provided with an annular drive groove 311. The annular drive groove 311 is set according to the outer contour of the cam 132 and has at least two basic positions A with the smallest radius and two protruding positions B with the largest radius. The basic positions A and the protruding positions B are staggered in the drive groove 311.

[0118] The clamping body 12 is provided with a drive shaft 221, which is inserted into the drive groove 311. When the cam 132 is driven to rotate, the drive shaft 221 slides along the drive groove 311.

[0119] When the control component moves relative to the plate 11 for the first time, it causes the cam 132 to rotate. The drive shaft 221 slides along the drive groove 311 and slides from the first protruding position of the drive groove 311 to the first basic position and is positioned at the first basic position, so that the clamping body 12 switches from the loose state to the clamping state and is positioned at the clamping state. When the control component moves relative to the plate 11 for the second time, it causes the cam 132 to rotate. The drive shaft 221 continues to slide along the drive groove 311 and slides from the first basic position of the drive groove 311 to the second protruding position and is positioned at the second protruding position, so that the clamping body 12 switches from the clamping state to the loose state and is positioned at the loose state.

[0120] For example, since the cam 132 is provided with an annular drive groove 311, the rotation direction of the cam 132 is the same when the control component moves for the first time and the second time. That is, when the user operates the control component, the cam 132 can rotate continuously in the same direction. For example, the cam 132 can rotate 90 degrees every time the control component moves. As the cam 132 rotates, the drive shaft 221 slides to the base position A and the protruding position B in sequence, realizing the state switching of the clamping component 12.

[0121] In one feasible embodiment, reference is made to... Figure 19 As shown, cam 132 is an elliptical cam, and the annular drive groove 311 is an elliptical groove.

[0122] In one feasible embodiment, clamping bodies 12 are movably disposed on opposite sides of the plate 11, and the drive shafts 221 of the two clamping bodies 12 are respectively inserted into the drive grooves 311. When the control member is driven to move relative to the plate 11 for the first time, it drives the cam 132 to rotate, and the drive shafts 221 of the two clamping bodies 12 slide along the drive grooves 311. The drive shaft 221 of the first clamping body 12 slides from the first protruding position of the drive groove 311 to the first basic position and is positioned at the first basic position, so that the first clamping body 12 switches from the released state to the clamping state and is positioned at the clamping state. At the same time, the drive shaft 221 of the second clamping body 12 slides from the second protruding position of the drive groove 311 to the second basic position and is positioned at the second basic position, so that the first clamping body 12 switches from the released state to the clamping state and is positioned at the clamping state. The two clamping bodies 12 also switch from the released state to the clamping state and are positioned in the clamping state; the control component moves relative to the plate 11 for the second time, causing the cam 132 to rotate, and the drive shafts 221 of both clamping bodies 12 continue to slide along the drive groove 311. The drive shaft 221 of the first clamping body 12 slides from the first base position of the drive groove 311 to the second protruding position and is positioned in the second protruding position, so that the first clamping body 12 switches from the clamping state to the released state and is positioned in the released state. At the same time, the drive shaft 221 of the second clamping body 12 slides from the second base position of the drive groove 311 to the first protruding position and is positioned in the first protruding position, so that the second clamping body 12 also switches from the clamping state to the released state and is positioned in the released state.

[0123] In one feasible embodiment, such as Figure 5 , Figure 14 and Figure 15 As shown, the control component is a control lever 2, which includes a first lever body 25 and a second lever body 26.

The first lever body 25 is driven to move towards or away from the second lever body 26 for the first time, causing the second lever body 26 to rotate for the first time. The rotation of the second lever body 26 causes the transmission part 13 to move. The movement of the transmission part 13 causes the clamping body 12 to move relative to the plate 11 so that the clamping body 12 can switch from the loose state to the clamping state. The first lever body 25 is driven to move towards or away from the second lever body 26 for the second time, causing the second lever body 26 to rotate for the second time. The rotation of the second lever body 26 causes the transmission part 13 to move. The movement of the transmission part 13 causes the clamping body 12 to move relative to the plate 11 so that the clamping body 12 can switch from the clamping state to the loose state.
