Description

Technical Field

[0001] This utility model relates to the field of daily cleaning products, specifically to a cloth clamping cleaning device. Background Technology

[0002] Mops are a common cleaning tool used in daily life. Most mops on the market use Velcro or snap-fit ​​to attach the cleaning material. While these methods allow for quick removal of the cleaning material, they require direct hand contact, which can easily contaminate hands with dirt and germs. Furthermore, aligning the cleaning material with the Velcro or snaps on the mop is a less than ideal experience.

[0003] Therefore, the installation and removal structure of the wiping material needs further optimization. Utility Model Content

[0004] One objective of this invention is to provide a cloth-clamping cleaning device that solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model is implemented through the following technical solutions:

[0006] A cloth clamping cleaning device includes a first cleaning head and a handle. The first cleaning head is provided with a hinge seat, a first clamping member, and a second clamping member. The first clamping member and the second clamping member are respectively movably installed on opposite sides of the first cleaning head. A second cleaning head is detachably connected to the handle or the first cleaning head. The second cleaning head is provided with a third clamping member and a fourth clamping member. The first clamping member and the second clamping member are driven to move by a first driving mechanism. The third clamping member and the fourth clamping member can move in conjunction with the first clamping member and the second clamping member, or can be driven to move by a second driving mechanism. Existing cloth clamping cleaning devices cannot adjust the size of the cleaning head. However, the cleaning head is needed to support the wiping material for effective cleaning. If a small-sized cleaning head is purchased, even if a larger wiping material is clamped, the unit area available for cleaning remains the same, which is still the area of ​​the cleaning head. Multiple sizes of cloth clamping cleaning devices are needed to meet various cleaning needs. The cloth clamping cleaning device of this invention has a second cleaning head that can be detachably installed on the handle or the first cleaning head. By adjusting the size of the cleaning head, the unit area cleaned by the cloth clamping cleaning device can be adjusted. Moreover, it can clamp and clean the wiping material regardless of whether it is switched to the first or the second cleaning head.

[0007] Preferably, the first driving mechanism includes a first push rod, a first connecting rod, and a second connecting rod. The two ends of the first connecting rod are rotatably connected to the first push rod and the first clamping member, respectively. The two ends of the second connecting rod are rotatably connected to the first push rod and the second clamping member, respectively. This controls the movement of the first push rod, and the first and second connecting rods respectively drive the first and second clamping members to move and clamp or remove the wiping material. By employing a linkage drive method using a push rod and connecting rods, the driving mechanism can be operated manually by pressing, stepping, or kicking by adjusting the position of the push rod, making it more versatile. Furthermore, the assembly of the components is simpler compared to a multi-link structure.

[0008] Preferably, the first driving mechanism includes a first upper plate and a first lower plate. The first lower plate is movable up and down relative to the first upper plate. During the movement of the first lower plate, the first clamping member and the second clamping member can move to clamp or remove the wiping material. Compared with traditional driving mechanisms, the pressing and moving clamping structure of the first upper plate and the first lower plate forms part of the driving mechanism. The movement of the clamping members to remove the wiping material is achieved by setting up an elastic member. There is no need to set up a separate component to form the driving mechanism. The structure is simpler and the cost is lower. Moreover, the wiping material can be clamped by pressing down the handle, so that the wiping material can be installed without bending over.

[0009] Preferably, the first drive mechanism is provided with a locking structure, which fixes the first clamping member and the second clamping member in a clamping state.

[0010] Preferably, the second cleaning head has a mounting cavity, into which the first cleaning head can be accommodated and detachably connected with a quick-release structure within the mounting cavity. The mounting cavity ensures that the first and second cleaning heads maintain a unified appearance after installation, with only a change in size, resulting in a more aesthetically pleasing product. Furthermore, installing the second cleaning head does not increase the height of the cleaning head section, allowing it to still access and clean crevices.

[0011] Preferably, the third and fourth clamping members extend into the mounting cavity, and the first cleaning head enters the mounting cavity. The first and second clamping members are respectively connected to the third and fourth clamping members. The first driving mechanism drives the first and third clamping members to move in the same direction, and the second and fourth clamping members also move in the same direction. Setting the second cleaning head to be linked with the first cleaning head reduces the number of driving mechanisms within the second cleaning head, and the direct connection between the first and third clamping members eliminates the need for a complex linkage structure, simplifying installation and reducing costs.

[0012] Preferably, the first and second drive mechanisms are independent, allowing the second cleaning head to be used as a standalone cleaning head. The second drive mechanism includes a second push rod, a third connecting rod, and a fourth connecting rod. The two ends of the third connecting rod are rotatably connected to the second push rod and the third clamping member, respectively. The two ends of the fourth connecting rod are rotatably connected to the second push rod and the fourth clamping member, respectively, controlling the movement of the second push rod. The third and fourth connecting rods respectively drive the third and fourth clamping members to move and clamp or remove the cleaning material. With the two drive mechanisms independently configured, the second cleaning head can be installed and removed from the cleaning material whether mounted on the handle or the first cleaning head, enabling it to simultaneously replace the first cleaning head and be used independently with the handle.

[0013] Preferably, the movement direction of the second push rod is different from that of the third clamping member and the fourth clamping member, and a third track is provided between the third connecting rod or the third clamping member and the second cleaning head. The third track prevents the third connecting rod and the third clamping member from moving in the direction of the second push rod, and drives the third clamping member to move in a direction perpendicular to the second push rod through the rotation and movement of the third connecting rod. Since the installation and movement space inside the cleaning head is limited, using the connecting rod to transfer the movement of the second push rod to the clamping member in another direction allows the second push rod, the third connecting rod, and the third clamping member to be installed in a vertically overlapping manner, improving space utilization.

[0014] Preferably, the second push rod, the third connecting rod, and the third clamping member are at least partially located on the same vertical plane. The second push rod is provided with a baffle, and the baffle has an angle with the third sliding section. During the movement of the second push rod, the third connecting rod, and the third clamping member, the angle between the baffle and the third sliding section remains the same. The second push rod, the third connecting rod, and the third clamping member are installed in a vertically overlapping manner to improve space utilization. When the second push rod, the third connecting rod, and the third clamping member are in the state of clamping the wiping object, the three are in a close-to-each-other position. The baffle can support the third connecting rod, preventing the third connecting rod from rotating in the storage position. The constant angle between the baffle and the third sliding section ensures that the movement of the three is always stable in the preset direction and angle, avoiding shaking and jamming of the three components.

[0015] Preferably, the second cleaning head has a second functional cavity and a third functional cavity on the periphery and bottom of the mounting cavity, respectively. The second drive mechanism is installed in the second functional cavity, and the second push rod has a clearance hole corresponding to the third functional cavity. The outer side of the second push rod is in contact with the edge of the second cleaning head to connect the third clamping member and the fourth clamping member, respectively. By using the same push rod to connect different clamping members on both sides simultaneously, the movements of the third clamping member and the fourth clamping member are always synchronized and the movement distance is always the same. The way the side of the second push rod is in contact with the second cleaning head can limit the movement direction of the second push rod and prevent the second push rod from shaking. Furthermore, the clearance hole of the second push rod can reduce the impact of the mounting cavity space on the second push rod and reduce the overall height of the second cleaning head.

[0016] Preferably, the first clamping member, the second clamping member, the third clamping member, and / or the fourth clamping member are provided with first clamping claws. The first clamping claws are movably connected to the corresponding clamping members. The first cleaning head and / or the second cleaning head are provided with first clamping teeth, and the first clamping claws are provided with second clamping teeth. The clamping gap between the first clamping teeth and the second clamping teeth can be automatically adjusted according to the thickness of the wiping material. The movable design of the first clamping claws allows the first clamping claws to automatically adjust the tightness between the two clamping teeth according to the thickness of the wiping material, even if the locking position of the locking structure is constant. This avoids the drawbacks of thin wiping materials not being able to be clamped or being clamped too tightly to be disassembled, or thick wiping materials not being able to be clamped due to the locking structure not being able to lock.

[0017] The advantages of this utility model are:

[0018] Existing cloth clamping cleaning devices cannot adjust the size of the cleaning head. However, the cleaning head is needed to support the wiping material for effective cleaning. If a small-sized cleaning head is purchased, even if a larger wiping material is clamped, the unit area available for cleaning remains the same, which is still the area of ​​the cleaning head. Multiple sizes of cloth clamping cleaning devices are needed to meet various cleaning needs. The cloth clamping cleaning device of this invention has a second cleaning head that can be detachably installed on the handle or the first cleaning head. By adjusting the size of the cleaning head, the unit area cleaned by the cloth clamping cleaning device can be adjusted. Moreover, it can clamp and clean the wiping material regardless of whether it is switched to the first or the second cleaning head.

[0019] It adopts a linkage drive method with tow rods and connecting rods. The drive mechanism can be operated manually by pressing, stepping, or kicking by adjusting the position of the push rod, making it more versatile. Moreover, the assembly of each component is simpler than that of a multi-link structure.

[0020] Compared with traditional drive mechanisms, the first upper plate and the first lower plate press and move clamping structure utilizes the movement between the first upper plate and the first lower plate to form part of the drive mechanism. By setting up elastic elements, the movement of the clamping parts to remove and detach the wiping material is realized. There is no need to set up a separate part to form a drive mechanism. The structure is simpler and the cost is lower. Moreover, the wiping material can be clamped by pressing down the handle, so that the wiping material can be installed without bending over.

[0021] Setting the second cleaning head to be linked with the first cleaning head can reduce the drive mechanism inside the second cleaning head, and the first clamping member and the third clamping member adopt a direct connection drive method, which eliminates the need to set up a complex linkage structure, simplifying installation and reducing costs.

[0022] The two drive mechanisms are set independently. The second cleaning head can be installed and removed from the cleaning head, whether it is installed on the handle or the first cleaning head. This allows the second cleaning head to be used to replace the first cleaning head and to be used independently connected to the handle. Attached Figure Description

[0049] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0050] This utility model uses certain terms to refer to specific components. Those skilled in the art will understand that this specification and claims do not distinguish components by differences in name, but rather by differences in function. It should be noted that, unless otherwise specified, when a component is described as "provided with," "located on," or "located on" another component, it can mean directly provided with or located on another component, or it may also mean there is a component in between; it can be an integral structure or a separate structure. When a component is described as "connected" to another component, it can mean a direct connection or a connection through a component in between; it can be an integral connection, a separate connection, or a contact fit. When a component is described as "located on another component," it does not necessarily mean that the component is located above or on top of the other component; it can be in other positions. The terms "upper," "lower," "left," "right," "high," "lower," and similar expressions used herein are based on the normal placement state of the product and are merely for illustrative purposes. The term "multiple" used herein refers to two or more items. The terms "vertical" and "horizontal" used in this article refer to a state that is roughly vertical or roughly horizontal within a reasonable margin of error, and do not necessarily have to be extremely precise.

[0051] like Figure 1-26 A cloth-clamping cleaning device includes a handle 1 rotatably connected to a first cleaning head 2. A first clamping member 3 and a second clamping member 4 are provided on opposite sides of the first cleaning head 2. The first clamping member 3 and the second clamping member 4 move closer or further apart relative to each other through a first driving mechanism. The first clamping member 3 and the second clamping member 4 move away from the first cleaning head 2 to an unfolded position. Clamping areas 5 are formed between the two sides of the first cleaning head 2 and the first clamping member 3 and the second clamping member 4, respectively. When the unfolded first cleaning head 2 is placed on top of the wiping material, the first clamping member 3 and the second clamping member 4 move towards each other, driving the wiping material in contact into the clamping area 5 until the wiping material is clamped by the first cleaning head 2, the first clamping member 3 and the second clamping member 4.

[0052] In order to change the size of the wiping material that the cloth clamping cleaning device can hold and the area that can be cleaned, the cloth clamping cleaning device also includes a second cleaning head 6. The cleaning area of ​​the second cleaning head 6 is different from that of the first cleaning head 2. At the same time, the second cleaning head 6 is detachably connected to the first cleaning head 2, or both the first cleaning head 2 and the second cleaning head 6 are detachably connected to the handle 1, thereby changing the size of the cleaning area of ​​the cleaning head connected to the handle 1. Example 1

[0053] In this embodiment, the specific structure of the first cleaning head 2 is described in reference to patent 202410736788.6, and will not be repeated here.

[0054] like Figure 1-4 The following describes the structure of the detachable connection between the first cleaning head 2 and the second cleaning head 6. Specifically, the second cleaning head 6 is larger than the first cleaning head 2. The top surface of the second cleaning head 6 has a mounting cavity 7 that is adapted to the first cleaning head 2. A quick-release mechanism is provided between the first cleaning head 2 and the mounting cavity 7 to realize the fixed connection and disassembly separation between the first cleaning head 2 and the second cleaning head 6. The second cleaning head 6 has a third clamping member 8 and a fourth clamping member 9 on opposite sides. The third clamping member 8 and the fourth clamping member 9 can be driven by the first clamping member 3 and the second clamping member 4, or a second driving mechanism independent of the first driving mechanism can be provided, so that the second cleaning head 6 can clamp a larger size of wiping material after installation, thereby expanding the cleaning area.

[0055] like Figure 2-4 The first cleaning head 2 and the second cleaning head 6 are detachably connected by a snap-fit ​​mechanism. The bottom of the first cleaning head 2 is provided with one or more slots 10, and the bottom of the mounting cavity 7 is provided with one or more upward protruding snaps 11. The snaps 11 are fixedly connected by cooperating with each slot 10. Each snap 11 is movable so that it can be disengaged from each slot 10 after being moved. The movable structure of each snap 11 can be controlled individually by setting a first unlocking switch 12, or it can be controlled by connecting to the same first unlocking switch 12 for one-button unlocking.

[0056] Preferably, the first unlocking switch 12 is located on the outside of the mounting cavity 7 to facilitate user operation. In this embodiment, the first unlocking switch 12 is slidably mounted on the top of the second cleaning head 6. Each buckle 11 is located on the same straight line and is simultaneously connected to the first unlocking switch 12 through the switch rod 13. Sliding the first unlocking switch 12 causes each buckle 11 to slide and change position simultaneously, so that the buckle 11 is separated from the slot 10.

[0057] In this embodiment, both the first cleaning head 2 and the second cleaning head 6 are rectangular. To facilitate the alignment of the buckle 11 and the slot 10 during the installation of the first cleaning head 2, the slot 10 is located at the center of the first cleaning head 2 or each slot 10 is mirrored along the center. The position of each buckle 11 in the mounting cavity 7 corresponds to the position of each slot 10 on the first cleaning head 2. The first cleaning head 2 and the second cleaning head 6 can be aligned in the length and width directions to achieve the alignment installation, without the need for either side to be specifically aligned with a preset side, thereby making the installation of the first cleaning head 2 and the second cleaning head 6 more convenient and simple.

[0058] Preferably, when the first cleaning head 2 is installed into the mounting cavity 7, the top of the first cleaning head 2 is approximately flush with the top of the second cleaning head 6, so that the first cleaning head 2 and the second cleaning head 6 are approximately a single unit.

[0059] In addition to the aforementioned snap-fit ​​structure 11, other quick-release structures can be used to achieve detachable fixing between the first cleaning head 2 and the second cleaning head 6, such as magnetic attraction, screw engagement, and pin engagement. The first cleaning head 2 can be installed by setting magnets, screws, pins, and other devices in the mounting cavity 7.

[0060] The first cleaning head 2 and the second cleaning head 6 are detachably connected to the handle 1. Specifically, a hinge 14 is provided between the bottom of the handle 1 and the first cleaning head 2 and the second cleaning head 6. The hinge 14 is rotatably connected to the handle 1 and the first cleaning head 2 or the second cleaning head 6, respectively. When replacing the first cleaning head 2 and the second cleaning head 6, the handle 1 is separated from the first cleaning head 2 or the second cleaning head 6, and then another cleaning head is installed on the handle 1, thereby realizing the replacement of the cleaning head. In this detachable structure, the first cleaning head 2 is equipped with a first driving mechanism to install the wiping material, and the second cleaning head 6 is equipped with a second driving mechanism to install the wiping material. During the replacement of the cleaning head, the corresponding driving mechanism is also replaced synchronously. That is, the first cleaning head 2 and the second cleaning head 6 are respectively equipped with independent first driving mechanisms and second driving mechanisms. Of course, the driving principle and structure of the first driving mechanism and the second driving mechanism can be the same or different.

[0061] Based on the detachable connection between the first cleaning head 2 and the second cleaning head 6, the second drive mechanism on the second cleaning head 6 can be used in a manner that is either linked or not linked with the first drive mechanism to enable the installation of the wiping material on the second cleaning head 6.

[0062] When a linkage structure is adopted, the movement of the first clamping member 3 and the second clamping member 4 on the first cleaning head 2 drives the third clamping member 8 and the fourth clamping member 9 on the second cleaning head 6 to open or clamp. This method can achieve linkage by setting a linkage, swing arm, gear set or other structure between the first cleaning head 2 and the second cleaning head 6.

[0063] like Figure 5-7 In this embodiment, the linkage mechanism is as follows: the first clamping member 3, the second clamping member 4, the third clamping member 8, and the fourth clamping member 9 extend and move in the same direction. The inner ends of the third clamping member 8 and the fourth clamping member 9 extend into the mounting cavity 7. The bottom of the first clamping member 3 and the second clamping member 4 are provided with linkage holes or linkage grooves 15. The third clamping member 8 and the fourth clamping member 9 are provided with linkage rods 16 at their positions in the mounting cavity 7. When the first cleaning head 2 is installed into the mounting cavity 7, each linkage rod 16 and each linkage groove 15 are connected. When the first clamping member 3 and the second clamping member 4 move, the third clamping member 8 and the fourth clamping member 9 are driven to move along with them through the connection of the linkage rods 16 and the linkage grooves 15, so as to install and remove the wiping material. This achieves the linkage mechanism between the first cleaning head 2 and the second cleaning head 6.

[0064] When the first drive mechanism and the second drive mechanism are not linked, in the state where the second cleaning head 6 is not installed, the first drive mechanism enables the first cleaning head 2 to be installed and removed from the wiping surface; in the state where the second cleaning head 6 is installed, the first drive mechanism does not operate, and the second drive mechanism operates to enable the second cleaning head 6 to be installed and removed from the wiping surface.

[0065] Specifically, such as Figure 3 , 8 -9. The second drive mechanism includes a second push rod 17, a third link 18, and a fourth link 19. The two ends of the third link 18 are rotatably connected to the second push rod 17 and the third clamping member 8, respectively. The two ends of the fourth link 19 are rotatably connected to the second push rod 17 and the fourth clamping member 9, respectively. The drag bar, the third clamping member 8, and the fourth clamping member 9 are all movably mounted on the second cleaning head 6. During the movement of the second push rod 17, the third link 18 and the fourth link 19 are simultaneously rotated and moved, thereby simultaneously moving the third clamping member 8 and the fourth clamping member 9.

[0066] The second cleaning head 6 includes a second upper plate 20 and a second lower plate 21. The second upper plate 20 has a mounting cavity 7 in the middle for the first cleaning head 2 to partially or entirely enter. The second upper plate 20 and the second lower plate 21 have a second functional cavity 22 around the mounting cavity 7. The second push rod 17, the third connecting rod 18, the fourth connecting rod 19, the third clamping member 8 and the fourth clamping member 9 are all installed in the second functional cavity 22.

[0067] Preferred, such as Figure 9-10To improve the clamping force of the second cleaning head 6 on the object to be wiped, the third clamping member 8 and the fourth clamping member 9 are movably mounted on the long side of the second cleaning head 6 and can move in a direction perpendicular to the long side, that is, parallel to the short side of the second cleaning head 6. The second push rod 17 moves in a direction parallel to the long side, so that the moving direction of the second push rod 17 is perpendicular to that of the third clamping member 8 and the fourth clamping member 9. The third connecting rod 18 and the fourth connecting rod 19 are set to transfer the movement of the drag rod to the third clamping member 8 and the fourth clamping member 9 in different directions.

[0068] In this embodiment, the third clamping member 8 includes a third sliding section 23 and a third clamping section 24, which are perpendicular to each other. The third sliding section 23 extends into the second functional cavity 22 and is rotatably connected to the third connecting rod 18. The fourth clamping member 9 includes a fourth sliding section 25 and a fourth clamping section 26, which are perpendicular to each other. The fourth sliding section 25 extends into the second functional cavity 22 and is rotatably connected to the fourth connecting rod 19.

[0069] Because the second push rod 17 pulls the third connecting rod 18 and the fourth connecting rod 19 to move synchronously during the movement, in order to prevent the third clamping member 8 and the fourth clamping member 9 from moving in the same direction as the second push rod 17, a third track 27 is provided in the second functional cavity 22. The third track 27 cooperates with the connecting rod or sliding section to limit the movement of the third clamping member 8 and the fourth clamping member 9 in the aforementioned preset direction, preventing the third clamping member 8 and the fourth clamping member 9 from moving in the direction of the second push rod 17. During the installation and removal of the wiping object, the second push rod 17 needs to move in two opposite directions, the third connecting rod 18 and the fourth connecting rod 19 need to move in two opposite directions, and the third clamping member 8 and the fourth clamping member 9 also need to move in two opposite directions. The connecting rod or sliding section is limited and guided in both opposite directions by the third track 27 or by the third track 27 and the fourth track 28 respectively limiting and guiding in the opposite directions.

[0070] The following explains the operating principle of the second drive mechanism: Controlling the movement of the second push rod 17 causes one end of the third link 18 to move and rotate following the second push rod 17. The other end of the third link 18 also rotates under the influence of the force. Under the action of the third track 27, the other end of the third link 18 cannot move in the same direction as the second push rod 17. The force on the other end of the third link 18 is blocked and its direction is changed by the third track 27. The direction of the force on the other end of the third link 18 and the third clamping member 8 is changed to the direction of the extension of the third track 27, causing the other end of the third link 18 and the third clamping member 8 to move or rotate along the third track 27 until the second drive mechanism reaches its preset maximum movable position. Positionally, the second push rod 17 moves in the opposite direction, causing one end of the third connecting rod 18 to move and rotate along with the second push rod 17. The other end of the third connecting rod 18 also rotates under pressure. Under the action of the third track 27 or the fourth track 28, the other end of the third connecting rod 18 cannot move in the same direction as the second push rod 17. The force on the other end of the third connecting rod 18 is blocked and its direction is changed by the third track 27 or the fourth track 28. The direction of the force on the other end of the third connecting rod 18 and the third clamping member 8 is changed to the direction of extension of the third track 27 or the fourth track 28, causing the other end of the third connecting rod 18 and the third clamping member 8 to move or rotate along the third track 27 or the fourth track 28. Similarly, the second push rod 17, the fourth connecting rod 19, and the fourth clamping member 9 also cooperate in the same way, which will not be described further in this embodiment.

[0071] Preferably, the third track 27 is configured as an elongated groove, and the pivot between the third sliding section 23 or the third connecting rod 18 and the third sliding section 23 is inserted into the third track 27, with both sides blocked and limited by the side walls of the third track 27. Of course, by adjusting the size of the third track 27 and setting a guide block near the third sliding section 23 on the third connecting rod 18, the movement and guidance of the third clamping member 8 can also be achieved.

[0072] When the third track 27 and the fourth track 28 are set at the same time, the third track 27 and the fourth track 28 are two baffles blocking in opposite directions. When the second push rod 17 moves in different directions, different baffles block at different positions of the third connecting rod 18 or the third sliding section 23 to play the role of track limiting and guiding. Based on this function, the two opposite side walls of the long groove can also be understood as the third track 27 and the fourth track 28 respectively.

[0073] The fourth link 19 and the fourth clamping member 9 also adopt the same structure as the third link 18 and the third clamping member 8 to cooperate with the third track 27 and / or the fourth track 28. The structure of the fourth link 19, the fourth clamping member 9, the third track 27 and the fourth track 28 will not be described again in this embodiment.

[0074] Preferably, during normal use, the second lower plate 21 is located below the second drive mechanism and supports its linkage. The third track 27 and / or the fourth track 28 are disposed on the second lower plate 21. The lower ends of the third sliding section 23 and the fourth sliding section 25 are provided with downwardly protruding guide blocks, or the pivot between the third connecting rod 18 and the third sliding section 23, and the pivot between the fourth connecting rod 19 and the fourth sliding section 25 extend downward to form guide blocks. The guide blocks cooperate with the third track 27 and the fourth track 28 on the lower second plate 21 for limiting and guiding. Even if there is an installation gap in the vertical direction of the second drive mechanism in the second functional cavity 22, the components of the second drive mechanism always tend to move downward under their own gravity, and the guide blocks are always located in the cooperating positions of the third track 27 and the fourth track 28, thereby making the operation of the second drive mechanism smoother.

[0075] Preferably, each end of the third clamping section 24 is provided with a third sliding section 23. The second push rod 17 extends to the two third sliding ends and is connected to each third sliding section 23 through different third connecting rods 18. This multi-point coordinated linkage makes the force on the third clamping member 8 more balanced and the movement smoother. Similarly, each end of the fourth clamping section 26 is provided with a fourth sliding section 25. The second push rod 17 extends to the two fourth sliding sections 25 and is connected to each fourth sliding section 25 through different fourth connecting rods 19. In this embodiment, the length of each connecting rod, the position of the rotational connection at both ends, and the length of each sliding section are all the same, so that when the same second push rod 17 moves, the activity state and distance of the third connecting rod 18 and the fourth connecting rod 19, the third clamping member 8 and the fourth clamping member 9 are always synchronized.

[0076] Preferably, the clamping and disassembly of the wiping object by the third clamping member 8 and the fourth clamping member 9 are achieved by the user operating the second push rod 17, or by setting a second elastic member 29 on the second drive mechanism, and using the elastic force of the second elastic member 29 to achieve the clamping or disassembly of the wiping object by the third clamping member 8 and the fourth clamping member 9. The second elastic member 29 can be installed between the two clamping members, between the clamping members and the second cleaning head 6, between the second push rod 17 and the second cleaning head 6, or between each rotating shaft, so as to achieve automatic clamping or disassembly of the wiping object.

[0077] In this embodiment, the second cleaning head 6 is further provided with a second locking structure, which locks the third clamping member 8 and the fourth clamping member 9 in a clamping state. Specifically, the second locking structure is disposed between the second push rod 17 and the second cleaning head 6, and includes a third locking tooth 30 and a fourth locking tooth 31. The third locking tooth 30 is disposed on the second push rod 17, and the fourth locking tooth 31 is disposed on the second upper plate 20. There are multiple fourth locking teeth 31, which are evenly spaced. The third locking tooth 30 can be inserted between any two fourth locking teeth 31 for locking and limiting.

[0078] Preferably, both the third locking tooth 30 and the fourth locking tooth 31 are ratchet teeth. When the third clamping member 8 and the fourth clamping member 9 move towards each other, the third locking tooth 30 and the fourth locking tooth 31 can move to the insertion and engagement position. In the opposite direction, the third locking tooth 30 and the fourth locking tooth 31 abut against each other and cannot move away, thereby keeping the third clamping member 8 and the fourth clamping member 9 in the state of clamping the wiping material. In this embodiment, when the third locking tooth 30 is engaged with different fourth locking teeth 31, the distance between the third clamping member 8, the fourth clamping member 9 and the second cleaning head 6 is changed to adapt to clamping wiping materials of different thicknesses.

[0079] When unlocking the second locking structure, the second push rod 17 or the third locking tooth 30 is pushed in the direction of the two locking teeth engaging, causing the third locking tooth 30 and the fourth locking tooth 31 to separate from the engagement position. This allows the second push rod 17 to be manually pushed or pulled, or the elastic force of the second elastic member 29 to automatically move the second push rod 17. The third clamping member 8 and the fourth clamping member 9 move from the clamping state to a disengaged state, releasing the wiping material. Besides unlocking by pushing the drag rod or the third locking tooth 30, unlocking can also be achieved by pushing the fourth locking tooth 31. Specifically, the second upper plate 20 is equipped with a third button, and the fourth locking tooth 31 is fixed below the third button. Pressing the third button separates the fourth locking tooth 31 from the third locking tooth 30, thereby unlocking the second push rod 17.

[0080] In the above embodiment, the second cleaning head 6 has a third functional cavity 32 directly below the mounting cavity 7. The switch rod 13 is located in the third functional cavity 32. Each buckle 11 enters the third functional cavity 32 downwards to connect with the switch rod 13. The second functional cavity 22 and the third functional cavity 32 are connected, allowing the switch rod 13 to enter the second functional cavity 22 laterally and connect with the first unlocking switch 12. Since the second push rod 17 needs to connect with the two third sliding sections 23 and the fourth sliding section 25 at both ends, the second push rod 17 is provided with a clearance hole 33. The switch rod 13 is located in the clearance hole 33, so that the second push rod 17 and the switch rod 13 are approximately on the same plane. This reduces the overall height of the third functional cavity 32 and the second cleaning head 6, and also prevents the switch rod 13 and the second push rod 17 from sliding against each other and causing obstruction when they are stacked.

[0081] Preferred, such as Figure 8The second push rod 17 can be connected in a way that is partially located in the second functional cavity 22 and partially located in the third functional cavity 32, or it can be connected in a way that is entirely located in the third functional cavity 32. Since the third connecting rod 18 is rotatably connected to the end position of the third sliding section 23, in order to shorten the cooperation movement path between the second push rod 17 and the third sliding section 23, it is necessary to increase the length of the third connecting rod 18 and the second push rod 17, and move the rotation connection point between the third connecting rod 18 and the second push rod 17 away from the rotation connection point between the third connecting rod 18 and the third sliding section 23. In this embodiment, the second push rod 17 is partially installed close to the edge position of the second cleaning head 6, so as to maximize the length of the third connecting rod 18. Meanwhile, the second push rod 17, the third connecting rod 18, and the third sliding section 23 are stacked vertically to reduce the lateral cooperation space between them. When the three components are clamping the object to be wiped closer together, at least part of the second push rod 17, the third connecting rod 18, and the third sliding section 23 are located on the same vertical plane. Specifically, the second push rod 17 is positioned at a lower level and is fitted against the second lower plate 21. An upwardly extending baffle 34 is provided on the second push rod 17, with hinge holes at both the upper and lower positions. The third connecting rod 18 is installed in the area between two hinge holes, allowing the third connecting rod 18 to... The vertical height does not exceed the vertical position of the baffle 34. The third sliding section 23 is also hinged to the third link 18 in the same way, so that the third sliding section 23 is approximately at the same height as the third link 18. The third link 18 is provided with a first clamping groove 35 on the side near the third sliding section 23. The end of the first clamping groove 35 is also provided with hinge holes in the vertical direction. When in the state of clamping the wiping object, at least part of the third sliding section 23 is accommodated in the first clamping groove 35, so as to reduce the lateral volume of the third link 18 and the third sliding section 23, making the second drive mechanism more compact in the second functional cavity 22.

[0082] Preferred, such as Figure 9-10 An angle is provided between the baffle 34 and the third sliding section 23 along the horizontal cross section, and the baffle 34 and the third sliding section 23 always maintain the same angle during the movement of the second push rod 17, the third connecting rod 18 and the third clamping member 8.

[0083] The specific structures of the second push rod 17, the fourth connecting rod 19, and the fourth clamping member 9 are the same as those of the second push rod 17, the third connecting rod 18, and the third clamping member 8 described above, and will not be repeated in this embodiment. The connection positions between the second push rod 17, the third connecting rod 18, and the third clamping member 8 are mirror images of the connection positions between the second push rod 17, the fourth connecting rod 19, and the fourth clamping member 9 along the centerline of the second cleaning head 6. The third connecting rod 18 and the fourth connecting rod 19, the third sliding section 23, and the fourth sliding section 25 have the same length, so that the movement between the two clamping members is always synchronized and the movement distance is the same.

[0084] Preferably, both sides of the second push rod 17 are in contact with the second lower plate 21. The second lower plate 21 limits the direction of movement of the second push rod 17 and prevents the second push rod 17 from shaking or deviating during movement.

[0085] In this embodiment, a second clamping groove 36 is provided on the side of the third track 27 away from the third sliding section 23. Sleeve rods 37 are provided on the third sliding section 23 and the fourth sliding section 25 at positions corresponding to the second clamping grooves 36. A second elastic element 29 is installed between the two sleeve rods 37. The second clamping prevents the second elastic element 29 from elastically disengaging from the sleeve rods 37 when compressed or stretched, and keeps the direction of the elastic force released by the second elastic element 29 aligned with the third sliding section 23 and the fourth sliding section 25. Alternatively, one second elastic element 29 can be installed between each sleeve rod 37 and the second clamping groove 36.

[0086] In the above embodiment, the second lower plate 21 is provided with third clamping teeth 38 on both sides, and the third clamping section 24 and the fourth clamping section 26 are provided with fourth clamping teeth 39. A clamping area 5 is formed between the third clamping teeth 38 and the fourth clamping teeth 39 to clamp the wiping object. Example 2

[0087] The similarities between this embodiment and Embodiment 1 will not be repeated here. Only the differences will be described. The difference between this embodiment and Embodiment 1 is: the first driving structure of the first cleaning head 2.

[0088] like Figure 11-16 In this embodiment, the first drive mechanism on the first cleaning head 2 adopts a structure that is substantially the same as the second drive mechanism in embodiment 1. Specifically, the first cleaning head 2 includes a first upper plate 41 and a first lower plate 42. A handle 1 is movably connected above the first upper plate 41. A first functional cavity 43 is provided between the first upper plate 41 and the first lower plate 42. The first drive mechanism is installed in the first functional cavity 43. The first drive mechanism includes a first push rod 44, a first connecting rod 45, and a second connecting rod 46. The two ends of the first connecting rod 45 are rotatably connected to the first push rod 44 and the first clamping member 3, respectively. The two ends of the second connecting rod 46 are rotatably connected to the first push rod 44 and the second clamping member 4, respectively. By controlling the movement of the first push rod 44, the first connecting rod 45 and the second connecting rod 46 rotate and move synchronously, driving the first clamping member 3 and the second clamping member 4 to move synchronously, so as to clamp or remove the wiping material.

[0089] The first clamping member 3 includes a first sliding section 47 and a first clamping section 48, and the second clamping member 4 includes a second sliding section 49 and a second clamping section 50. The installation method and position of the first sliding section 47, the first clamping section 48, the first connecting rod 45, and the first push rod 44, as well as the installation method and position of the second sliding section 49, the second clamping section 50, the second connecting rod 46, and the first push rod 44, are the same as those of the components in the second drive mechanism in Embodiment 1, and will not be described again in this embodiment. Similarly, the first lower plate 42 is also provided with a first track 51 and / or a second track 52 that have the same function as the third track 27 and the fourth track 28, so as to limit the movement of the two clamping members and the two connecting rods to a preset position and direction. The first drive mechanism is also provided with a first elastic member, and the elastic force of the first elastic member enables one-button automatic removal of the wiping object.

[0090] It can be understood that the principle and structure of the first cleaning head 2 and the first driving mechanism in this embodiment is to connect the second cleaning head 6 and the second driving structure to the handle 1 in a whole after removing the mounting cavity 7, with the only difference being the size between the first cleaning head 2 and the second cleaning head 6.

[0091] In this embodiment, the top of the first upper plate 41 is provided with two hinge seats 53, and a hinge member 14 is provided between the two hinge seats 53. The two sides of the hinge member 14 are rotatably connected to the handle 1 and the hinge seat 53 respectively. A first button 54 is movably connected to the side of one of the hinge seats 53. One end of the first button 54 extends out from the side of the hinge seat 53, and the other end is linked with the first push rod 44. By pressing the first button 54 into the hinge seat 53, the push rod is driven to move, thereby causing the first clamping member 3 and the second clamping member 4 to move towards each other to clamp the wiping object.

[0092] Preferably, the first driving mechanism is also provided with a first locking structure, which includes a first locking tooth 55 and a second locking tooth 56. The first locking tooth 55 is provided on the first push rod 44. The first upper plate 41 or the hinge seat 53 is provided with a movable second button 57. One end of the second button 57 extends from the first upper plate 41 or the hinge seat 53, and the other end is provided with the second locking tooth 56. A third elastic member is provided between the second button 57 and the first upper plate 41 or the hinge seat 53. The movement of the second button 57 can drive the second locking tooth 56 to engage or disengage with the first locking tooth 55. The elastic force of the third elastic member causes the second locking tooth 56 to tend to move closer to the first locking tooth 55 or to remain engaged with the first locking tooth 55. Multiple first locking teeth 55 are provided, so that the first locking structure has a multi-level adjustable locking function. When different thicknesses of wiping materials are installed, the second locking tooth 56 engages with different first locking teeth 55 to lock.

[0093] In addition to the above structures, such as Figure 16Alternatively, the first button 54 can be omitted from the hinge base 53. Instead, the first push rod 44 can be extended from the side of the first cleaning head 2, and the first push rod 44 can be pressed and pushed to drive the first clamping member 3 and the second clamping member 4 to move. Similarly, the second locking tooth 56 can also be changed in position and set on the first upper plate 41 or the first lower plate 42. The second button 57 is still movably installed on the hinge base 53. Pressing the hinge base 53 moves and pushes the first locking tooth 55 or the second locking tooth 56 to deform and separate from the other cooperating locking tooth, thereby allowing the first drive mechanism to be unlocked and operated.

[0094] Preferably, the first lower plate 42 is provided with first clamping teeth 58 on both sides, and the first clamping section 48 and the second clamping section 50 are provided with second clamping teeth 59. A clamping area 5 is formed between the first clamping teeth 58 and the second clamping teeth 59 to clamp the wiping object. Example 3

[0095] The difference between Example 3 and Examples 1 and 2 is that Example 3 uses a different first driving mechanism.

[0096] like Figure 17-22 In this embodiment, the first cleaning head 2 includes a first upper plate 41 and a first lower plate 42, which are connected by a snap-fit ​​mechanism and can be floated vertically. A first functional cavity 43 is formed between the first upper plate 41 and the first lower plate 42. A first clamping member 3 and a second clamping member 4 are movably installed in the first functional cavity 43. A fourth elastic member 61 and a fifth elastic member 62 are provided in the first functional cavity 43. The elastic force of the fourth elastic member 61 causes the first upper plate 41 and the first lower plate 42 to move away from each other, and the elastic force of the fifth elastic member 62 causes the first clamping member 3 and the second clamping member 4 to move away from each other and open.

[0097] Specifically, a clamping opening 60 is provided between the first upper plate 41 and the first lower plate 42 for the first clamping member 3 and the second clamping member 4 to pass through. The upper surface of the first lower plate 42 is provided with a fifth track 63. The first sliding section 47 and the second sliding section 49 are movably mounted on the fifth track 63 and are limited by the limiting guide of the fifth track 63 to move in a preset direction. During the movement of the first upper plate 41 and the first lower plate 42 away from each other, the first clamping member 3 and the second clamping member 4 move downward with the first lower plate 42. The fifth elastic member 62 releases elastic force to make the first clamping member 3 and the second clamping member 4 extend out from the clamping opening 60.

[0098] Preferably, a limiting block 64 is provided on the fifth track 63. The limiting block 64 is located above the first clamping member 3 and the second clamping member 4, and clamps the first clamping member 3 and the second clamping member 4 between the limiting block 64 and the first lower plate 42 or the fifth track 63, so that the first clamping member 3 and the second clamping member 4 are fixed to the first lower plate 42 in the vertical direction, so as to move up and down synchronously with the first lower plate 42.

[0099] In typical cleaning heads, such as those in Examples 1 and 2, a clamping opening 60 is provided on the side where the clamping member is located. If the lower plate is flat, the upper plate needs to reduce the height of the flange 65 at the position corresponding to the clamping member, or even provide the clamping opening 60 without flange 65 at that position, so that the clamping member can pass through the clamping opening 60 laterally. The upper plate and the lower plate are fixed together, and the clamping member always moves on the same plane and is always located on the same plane as the clamping opening 60. In this embodiment, the first upper plate 41 and the first lower plate 42 are connected vertically and horizontally. Compared with ordinary clamping components, the first clamping component 3 and the second clamping component 4 have different modes of movement. The first clamping component 3 and the second clamping component 4 can move in both vertical and horizontal directions during the clamping or disassembling of the wiping object. According to this principle of movement, the structure of the clamping opening 60 in this embodiment needs to be adjusted so that when the first upper plate 41 and the first lower plate 42 are close or attached, the first clamping component 3 and the second clamping component 4 will not be extended from the horizontal clamping opening 60 by the elastic force of the fifth elastic component 62.

[0100] Specifically, the four sides of the first upper plate 41 are provided with downwardly extending flanges 65. The height of the flanges 65 is approximately flush with the first lower plate 42 after installation, so as to surround the outer periphery of the first lower plate 42. The dimensions of the two sides of the first lower plate 42 in the length direction are reduced to form a clamping opening 60 between them and the flanges 65 of the first upper plate 41. The first clamping member 3 and the second clamping member 4 are installed at the clamping opening 60. The outer sides of the first clamping member 3 and the second clamping member 4 in the horizontal direction are blocked by the flanges 65 and cannot move outward. The fifth elastic member 62 can push the first clamping member 3 and the second clamping member 4 to open outward only when the first lower plate 42 moves the first clamping member 3 and the second clamping member 4 downward and misaligns with the flanges 65.

[0101] In order to keep the first cleaning head 2 in a clamped state for wiping the object, the first cleaning head 2 is provided with a third locking structure. The third locking structure includes a locking hook 66, which is movably mounted on the hinge seat 53 of the first upper plate 41. The locking hook 66 can change the cooperation relationship with the first lower plate 42. When the locking hook 66 hooks the first lower plate 42, the first lower plate 42 cannot move downward relative to the upper plate. When the locking hook 66 moves, it releases the restriction from the first lower plate 42, and the first lower plate 42 can move downward.

[0102] In a typical cleaning head, pressing down on the handle 1 drives the drive mechanism to clamp the cleaning material. However, in this embodiment, the first cleaning head 2, when pressing down on the handle 1, can only drive the first upper plate 41 and the first lower plate 42 to move towards each other. In order to drive the first clamping member 3 and the second clamping member 4 to automatically clamp the cleaning material under the pressure of the handle 1, in this embodiment, the first clamping member 3, the second clamping member 4, and the first upper plate 41 are guided by an inclined plane, which switches the upward movement of the first lower plate 42 to the horizontal movement of the first clamping member 3 and the second clamping member 4, thereby automatically clamping the cleaning material.

[0103] Specifically, such as Figure 20-21 The outer side of the first clamping section 48 is provided with a first inclined surface 67, and the inner side of the flange 65 of the first upper plate 41 is provided with a second inclined surface 68. Both the first inclined surface 67 and the second inclined surface 68 are inclined in the direction where the lower end is on the outer side and the upper end is on the inner side. During the opening and clamping process of the first clamping member 3, the first inclined surface 67 and the second inclined surface 68 are always in contact and abutting each other, so that when the first lower plate 42 moves upward, the first inclined surface 67 and the second inclined surface 68 immediately enter the mating position to push the first clamping member 3 to retract and move.

[0104] Preferred, such as Figure 21 When the first clamping member 3 and the first lower plate 42 move downward to the limit position, at least part of the first inclined surface 67 and the second inclined surface 68 still have horizontally overlapping areas, or even at least part of the first inclined surface 67 and the second inclined surface 68 still remain in a state of contact and abutment, thereby avoiding the first inclined surface 67 and the second inclined surface 68 from separating and getting stuck or misaligned when moving upward, thus preventing them from working together.

[0105] The second clamping member 4 and the first upper plate 41 also adopt the same structure, which will not be described again in this embodiment.

[0106] Preferably, the first lower plate 42 is provided with a groove 69 below the fifth track 63. The first sliding section 47 and the second sliding section 49 cooperate with different grooves 69 to limit the length range in which the first clamping member 3 and the second clamping member 4 can open relative to the first cleaning head 2, thereby keeping the first inclined surface 67 and the second inclined surface 68 in a position that always overlaps or fits.

[0107] In the above embodiment, the first upper plate 41 and the first lower plate 42 are guided and moved together. The first upper plate 41 and the first lower plate 42 are respectively provided with a first slide rod 70 and a second slide rod 71 of different sizes at each corner position. The first slide rod 70, the second slide rod 71 and the first clamping member 3 and the second clamping member 4 are misaligned to avoid the slide rods and clamping members affecting each other's movement.

[0108] Preferably, the size of the first slide rod 70 is smaller than the size of the second slide rod 71. The first slide rod 70 can slide up and down inside the second slide rod 71. The lower end of the first slide rod 70 is provided with an outwardly protruding first limiting ring 72, and an insert block 73 is provided above the first limiting ring 72. The side of the second slide rod 71 is provided with vertically extending deformation slots 74 to split the second slide rod 71 in half or into more pieces. The upper end of the second slide rod 71 is provided with an inwardly protruding second limiting ring 75. The limiting ring 72 and the second limiting ring 75 overlap. During installation, the first upper plate 41 and the first lower plate 42 are pressed down from above and below. The first limiting ring 72 pushes the second limiting ring 75 to make the second slide rod 71 open outward. The first slide rod 70 and the first limiting ring 72 can pass through the second limiting ring 75 and enter the second slide rod 71. The insert block 73 is inserted into the deformation joint 74 at the corresponding position and supports the second slide rod 71 on the side, reducing the relative movement of the first upper plate 41 and the second upper plate 20.

[0109] In this embodiment, a fourth elastic element 61 is sleeved on the outer side of the second slide rod 71, the first sliding section 47 and the second sliding section 49 are stacked one on top of the other, and the fifth elastic element 62 is installed between the first sliding section 47 and the second sliding section 49 to directly and synchronously control the movement of the first clamping member 3 and the second clamping member 4.

[0110] Similarly, the first lower plate 42 is provided with first clamping teeth 58 on both sides, and the first clamping section 48 and the second clamping section 50 are provided with second clamping teeth 59. The clamping area 5 is formed between the first clamping teeth 58 and the second clamping teeth 59 to clamp the wiping object.

[0111] In the above embodiment, the movement of the first clamping member 3 and the second clamping member 4 is driven by the fourth elastic member 61 to move the first lower plate 42, and then by the fifth elastic member 62. During the clamping process, the first clamping member 3 and the second clamping member 4 move towards each other through the guidance of the first inclined surface 67 and the second inclined surface 68. It can be understood that the first upper plate 41, the first lower plate 42, the fourth elastic member 61, the fifth elastic member 62, the first inclined surface 67, the second inclined surface 68, and other correspondingly provided components are all components required to drive the movement of the first clamping member 3 and the second clamping member 4. That is, the first driving mechanism in this embodiment includes all the components described above. Example 4

[0112] The difference between Example 4 and Examples 1-3 is that the second clamping tooth 59 is movably connected to the clamping member.

[0113] Specifically, the outer end of the first clamping member 3 is provided with a first clamping claw 76, which is movably connected to the first clamping member 3. A sixth elastic member 77 is provided between the first clamping claw 76 and the first clamping member 3. The first cleaning head 2 is provided with a first clamping tooth 58, and the first clamping claw 76 is provided with a second clamping tooth 59. The first clamping member 3 can move closer to or further away from the first cleaning head 2 to change the distance between the first clamping tooth 58 and the second clamping tooth 59. When the first clamping tooth 58 and the second clamping tooth 59 are close together or engaged, the wiping material is clamped. The thickness of the wiping material changes the clamping distance between the first clamping tooth 58 and the second clamping tooth 59. The elastic force of the sixth elastic member 77 makes the first clamping tooth 58 and the second clamping tooth 59 tend to move closer together to clamp the wiping material.

[0114] like Figure 26 The first gripper 76 includes a first clamping section 48 and a first telescopic section 78. The first clamping section 48 is provided with second clamping teeth 59. Each first clamping tooth 58 and each second clamping tooth 59 extends and is arranged along the side of the first cleaning head 2. The first clamping section 48 is directionally mounted on the first clamping member 3 so that the first clamping teeth 58 and the second clamping teeth 59 remain parallel when the first gripper 76 moves. Specifically, the first clamping member 3 includes a first sliding section 47 and a first guide groove 79. The first guide groove 79 and the first sliding section 47 are fixedly connected or the first guide groove 79 is disposed on the first sliding section 47. The first guide groove 79 is provided with a first stop 80. The first telescopic section 78 is provided with a first telescopic hole 81. A second stop 82 is provided in the first telescopic hole 81. The first stop 80 is inserted into the first telescopic hole 81 for installation. The first stop 80 and the second stop 82 are respectively located on opposite sides of the first telescopic hole 81. The gap between the first stop 80 and the second stop 82 is used to install the sixth elastic member 77. The first sliding section 47 is inserted into the first guide groove 79. The first sliding section 47 is moved and limited by the inner walls of the first guide groove 79. The first telescopic hole 81, the first stop 80 and the second stop 82 are set. The first stop 80 and the second stop 82 intersect to extend the length of the sixth elastic member 77 or the telescopic length of the sixth elastic member 77. The first gripper 76 moves outward to drive the second stop 82 to move outward to squeeze the sixth elastic member 77 and change the elastic force.

[0115] The working principle of the first cleaning head 2 in this embodiment is as follows: there is a preset active stroke between the first clamping member 3 and the first cleaning head 2, and it can be positioned after moving to the unfolded and retracted position. When clamping the wiping material, the active first clamping claw 76 drives the flat wiping material to roll up and enter the position between the first clamping tooth 58 and the second clamping tooth 59 until the first clamping tooth 58 and the second clamping tooth 59 are misaligned and meshed to clamp the wiping material. Due to the obstruction of the thickness of the wiping material, the first clamping tooth 58 and the second clamping tooth 59 cannot continue to move closer. If the thickness of the wiping material is greater than the preset clamping gap between the first clamping tooth 58 and the second clamping tooth 59, the first clamping member 3 moves to the preset locking position, and the thickness of the wiping material will push the first clamping claw 76 away from the first cleaning head 2. The elastic force of the sixth elastic member 77 pulls the first clamping claw 76 to clamp the wiping material.

[0116] Based on this principle, the preset clamping gap between the first clamping tooth 58 and the second clamping tooth 59 can be set in the following two ways: the first is, as shown below. Figure 23 On the lower side, the preset clamping gap between the first clamping tooth 58 and the second clamping tooth 59 is zero, that is, the first clamping tooth 58 and the second clamping tooth 59 are misaligned and fit together or abut against each other, clamping wiping material of any thickness. The wiping material causes the second gripper 83 to move outward to clamp the wiping material. In this way, the elastic force of the sixth elastic element 77 always increases the tension force on wiping materials of different thicknesses. Even if wear or locking gaps occur between the first clamping element 3 and the first cleaning head 2, the wiping material can still be clamped by the action of the sixth elastic element 77; the second type is, such as Figure 23 On the upper side, the preset clamping gap between the first clamping tooth 58 and the second clamping tooth 59 is set to the thickness of conventional paper towels and wet wipes on the market. When clamping thin wiping materials such as paper towels and wet wipes, the first gripper 76 does not move outward and the sixth elastic member 77 does not provide tension. When clamping thick wiping materials such as rags, mops, and multi-layer paper towels, the first gripper 76 moves outward and the sixth elastic member 77 provides tension.

[0117] In both of the above methods, the first gripper 76 can adjust the clamping gap between the first clamping tooth 58 and the second clamping tooth 59 according to the thickness of the wiping material, so that different wiping materials are clamped stably and will not be pierced or hooked by the clamping teeth and difficult to disassemble.

[0118] Of course, the range of extension and retraction of the first gripper 76 is determined by the size of the first cleaning head 2 and the length of the first extension segment 78. If the size of the first cleaning head 2 is larger, the length of the first extension segment 78 can be set to be larger, and the thickness range of the wiping material that the first gripper 76 can adapt to during extension and retraction is larger.

[0119] Preferably, the first gripper 76 structure on the first clamping member 3 can be correspondingly disposed on the second clamping member 4, the third clamping member 8, or the fourth clamping member 9.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
