Description

Technical Field

[0001] The present invention relates to the field of daily cleaning products, and in particular to a cloth-clamped cleaning device. Background Art

[0002] Mops are a common cleaning tool in daily life. Most mops on the market currently use Velcro or snap-on attachments to attach the wipe. These attachments offer the advantage of quick removal. However, both installation and removal require direct contact with the wipe, which can easily contaminate hands with stains and germs. Furthermore, installation requires aligning the wipe with the Velcro or snap-on attachment, resulting in a poor user experience.

[0003] Therefore, the installation and disassembly structure of the wiper needs to be further optimized. Summary of the Invention

[0004] An object of the present invention is to provide a cloth-gripping cleaning device that solves the above-mentioned problems.

[0005] To achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: A cloth-clamping cleaning device comprises a first cleaning head and a handle, wherein the first cleaning head is provided with a hinged seat, a first clamping member and a second clamping member, the first clamping member and the second clamping member are movably mounted on opposite sides of the first cleaning head respectively, the handle or the first cleaning head is detachably connected to the second cleaning head, and 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, and the third clamping member and the fourth clamping member are moved by the linkage cooperation of the first clamping member and the second clamping member, or are driven to move by a second driving mechanism. The existing cloth-clamped cleaning device cannot adjust the size of the cleaning head, and the wiping object needs to be supported by the cleaning head during cleaning to have a wiping cleaning effect. If a small-sized cleaning head is purchased, even if a larger wiping object is clamped, the unit area that the wiping object can be used for cleaning remains unchanged, and it is still the area of ​​the cleaning head. It is necessary to purchase cloth-clamped cleaning devices of multiple sizes to meet the cleaning needs of various sizes. The cloth-clamped cleaning device in the present invention can adjust the unit area cleaned by the cloth-clamped cleaning device by detachably installing the second cleaning head on the handle or the first cleaning head. By adjusting the size of the cleaning head, the unit area cleaned by the cloth-clamped cleaning device is adjusted, and whether switching to the first cleaning head or the second cleaning head, the cleaning head can be clamped to clean the wiping object.

[0006] Preferably, the first drive mechanism includes a first push rod, a first connecting rod, and a second connecting rod. The first connecting rod is rotatably connected to the first push rod and the first clamping member at both ends, and the second connecting rod is rotatably connected to the first push rod and the second clamping member at both ends. Controlling the movement of the first push rod drives the first clamping member and the second clamping member to move and clamp or remove the wipe. By adopting a linkage drive method between the push rod and the connecting rod, the drive mechanism can be operated by manual pressing, foot pressing, kicking, and other methods by adjusting the position of the push rod, providing greater versatility in use and simplifying assembly of components compared to a multi-link structure.

[0007] Preferably, the first driving mechanism includes a first upper plate and a first lower plate, the first lower plate being movable up and down relative to the first upper plate, and the first clamping member and the second clamping member being movable to clamp or remove the wiper during the movement of the first lower plate. Compared with a traditional driving mechanism, the first upper plate and the first lower plate are pressed to move the clamping structure. The movement between the first upper plate and the first lower plate forms part of the driving mechanism, and the elastic member is provided to enable the clamping member to move and remove the wiper. This eliminates the need for separate components to form a driving mechanism, resulting in a simpler structure and lower costs. Furthermore, the wiper can be clamped by pressing the handle downward, allowing installation without bending over.

[0008] Preferably, a locking structure is provided on the first driving mechanism, and the locking structure fixes the first clamping member and the second clamping member in a clamping state.

[0009] Preferably, the second cleaning head is provided with a mounting cavity, into which the first cleaning head can be accommodated and detachably connected to a quick-release structure within the mounting cavity. The provision of the mounting cavity ensures that the first and second cleaning heads remain a single unit after installation, differing only in size, thus enhancing the overall aesthetics of the product. Furthermore, installing the second cleaning head does not increase the height of the cleaning head, allowing it to fit into crevices for cleaning.

[0010] Preferably, the third clamp and the fourth clamp extend into the mounting cavity, the first cleaning head enters the mounting cavity, the first clamp and the second clamp are connected to the third clamp and the fourth clamp, respectively, and the first drive mechanism drives the first clamp and the third clamp to move in the same direction, and the second clamp and the fourth clamp to move in the same direction. Arranging the second cleaning head to be linked to the first cleaning head can reduce the number of drive mechanisms within the second cleaning head, and the direct connection drive between the first and third clamps eliminates the need for a complex linkage structure, thereby simplifying installation and reducing costs.

[0011] Preferably, the first drive mechanism and the second drive mechanism are independent, so that the second cleaning head can be used as a separate 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 respectively rotatably connected to the second push rod and the third clamping member, and the two ends of the fourth connecting rod are respectively rotatably connected to the second push rod and the fourth clamping member. The second push rod is controlled to move, and the third connecting rod and the fourth connecting rod respectively drive the third clamping member and the fourth clamping member to move to clamp or remove the wipe. The two drive mechanisms are independently provided, and the second cleaning head can be installed and removed regardless of whether it is installed on the handle or on the first cleaning head, so that the second cleaning head can simultaneously replace the first cleaning head and be used separately when connected to the handle.

[0012] Preferably, the movement direction of the second push rod is different from the movement direction 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 movement 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. Due to the limited installation and movement space within the cleaning head, the connecting rod is used to transfer the movement of the second push rod to the clamping member in the other direction. The second push rod, the third connecting rod, and the third clamping member can be installed in an overlapping manner to improve space utilization.

[0013] 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 an angle is formed between the baffle and 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 an overlapping manner to improve space utilization. When the second push rod, the third connecting rod, and the third clamping member are in a state of clamping the wipe, the three are in a close position. The baffle can support the third connecting rod to prevent the third connecting rod from rotating in the storage position. The angle between the baffle and the third sliding section is constant, so that the movement of the three components is always stable in a preset direction and angle, avoiding shaking and jamming of the three components.

[0014] Preferably, the second cleaning head is provided with a second functional cavity and a third functional cavity on the periphery and bottom of the mounting cavity, respectively. The second driving mechanism is mounted in the second functional cavity, and the second push rod is provided with a clearance hole corresponding to the third functional cavity. The outer side of the second push rod is aligned 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 simultaneously connect different clamping members on both sides, the movement of the third clamping member and the fourth clamping member are always synchronized and the movement distance is always the same. The way in which the side of the second push rod is aligned with the second cleaning head can limit the movement direction of the second push rod and prevent the second push rod from shaking. In addition, the clearance hole of the second push rod can reduce the impact of the mounting cavity space on the second push rod, thereby reducing the overall height of the second cleaning head.

[0015] Preferably, the first clamping member, the second clamping member, the third clamping member and / or the fourth clamping member are provided with a first clamping jaw, the first clamping jaw is movably connected to the corresponding clamping member, the first cleaning head and / or the second cleaning head are provided with a first clamping tooth, the first clamping jaw is provided with a second clamping tooth, and the clamping gap between the first clamping tooth and the second clamping tooth can be automatically adjusted according to the thickness of the wipe. The first clamping jaw is movable, so that even if the locking position of the locking structure is constant, the first clamping jaw itself can automatically adjust the tightness between the two clamping teeth according to the thickness of the clamped wipe, so as to avoid the disadvantages of thin wipes being unable to be clamped or being clamped too tightly and unable to be removed, or thick wipes being unable to be clamped due to the locking structure being unable to lock.

[0016] The advantages of the present invention are: The existing cloth-clamped cleaning device cannot adjust the size of the cleaning head, and the wiping object needs to be supported by the cleaning head during cleaning to have a wiping cleaning effect. If a small-sized cleaning head is purchased, even if a larger wiping object is clamped, the unit area that the wiping object can be used for cleaning remains unchanged, and it is still the area of ​​the cleaning head. It is necessary to purchase cloth-clamped cleaning devices of multiple sizes to meet the cleaning needs of various sizes. The cloth-clamped cleaning device in the present invention can adjust the unit area cleaned by the cloth-clamped cleaning device by detachably installing the second cleaning head on the handle or the first cleaning head. By adjusting the size of the cleaning head, the unit area cleaned by the cloth-clamped cleaning device is adjusted, and whether switching to the first cleaning head or the second cleaning head, the cleaning head can be clamped to clean the wiping object.

[0017] It adopts a tow rod and connecting rod linkage drive mode. The operation of the driving mechanism can be achieved by manual pressing, foot stepping, kicking, etc. by adjusting the position of the push rod. It is more versatile to use and the assembly of each component is simpler than the multi-link structure.

[0018] The first upper plate and the first lower plate are pressed to move the clamping structure. Compared with the traditional driving mechanism, the movement between the first upper plate and the first lower plate forms a part of the driving mechanism, and the movement of the clamping member is realized by setting an elastic member to remove the wiping object. There is no need to set up a separate component to form a driving mechanism. The structure is simpler and the cost is lower. The wiping object can be clamped by pressing the handle downward, so that the wiping object can be installed without bending over.

[0019] The second cleaning head is arranged to be linked with the first cleaning head, which can reduce the driving mechanism in the second cleaning head. The first clamping member and the third clamping member are directly connected and driven without setting up a complex linkage structure, simplifying installation and reducing costs.

[0020] The two driving mechanisms are independently arranged, and the second cleaning head can be installed and removed from the wiper no matter it is installed on the handle or on the first cleaning head, so that the second cleaning head can simultaneously replace the first cleaning head and be used separately when connected to the handle.

[0047] The following describes in detail the embodiments of the present invention in conjunction with the accompanying drawings, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0049] like Figure 1-26 , a cloth-clamping cleaning device includes a handle 1 and a first cleaning head 2 that are rotatably connected, and 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 are relatively movable close to or away from each other through a first driving mechanism, and the first clamping member 3 and the second clamping member 4 move away from the first cleaning head 2 to the unfolded position, and 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. The unfolded first cleaning head 2 is placed as a whole above the wiping object, and the first clamping member 3 and the second clamping member 4 move toward each other, driving the contact part of the wiping object to enter the clamping area 5 until the part of the wiping object is clamped by the first cleaning head 2, the first clamping member 3 and the second clamping member 4.

[0050] In order to change the size of the wiping object that can be clamped by the cloth-clamped cleaning device and the area that can be cleaned, the cloth-clamped cleaning device also includes a second cleaning head 6. The cleaning area of ​​the second cleaning head 6 is different from the cleaning area of ​​the first cleaning head 2. At the same time, the second cleaning head 6 is connected to the first cleaning head 2 in a detachable manner, or the first cleaning head 2 and the second cleaning head 6 are both 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

[0051] In this embodiment, the specific structure of the first cleaning head 2 refers to Patent 202410736788.6 and will not be repeated in this embodiment.

[0052] 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 size of the second cleaning head 6 is larger than that of the first cleaning head 2, and the top surface of the second cleaning head 6 is provided with a mounting cavity 7 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 achieve fixed connection and detachable separation between the first cleaning head 2 and the second cleaning head 6. A third clamping member 8 and a fourth clamping member 9 are provided on opposite sides of the second cleaning head 6, respectively. 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 sized wipe after installation, thereby expanding the cleaning area.

[0053] like Figure 2-4 The first cleaning head 2 and the second cleaning head 6 are detachably connected by a snap-fit ​​method. One or more snap-fit ​​grooves 10 are provided at the bottom of the first cleaning head 2, and one or more snap-fit ​​grooves 11 protruding upward are provided at the bottom of the mounting cavity 7. The fixed connection is achieved by cooperating with each snap-fit ​​groove 10. Each snap-fit ​​groove 11 is movably provided to disengage from each snap-fit ​​groove 10 after the activity. The movable structure of each snap-fit ​​groove 11 can be individually controlled by respectively setting a first unlocking switch 12, or can be controlled by connecting to the same first unlocking switch 12 to control the unlocking with one button.

[0054] Preferably, the first unlocking switch 12 is arranged on the outside of the mounting cavity 7 to facilitate user operation. In this embodiment, the first unlocking switch 12 is slidably installed on the top of the second cleaning head 6, and each buckle 11 is located on the same straight line and is connected to the first unlocking switch 12 through the switch rod 13 at the same time. Sliding the first unlocking switch 12 causes each buckle 11 to slide and change position at the same time, so that the buckle 11 is separated from the card slot 10.

[0055] In this embodiment, the first cleaning head 2 and the second cleaning head 6 are both configured to be rectangular. In order to facilitate the alignment of the clip 11 and the slot 10 when installing the first cleaning head 2, the slot 10 is set at the center position of the first cleaning head 2 or each slot 10 is set along the center mirror image. The position of each clip 11 in the installation 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 alignment and installation, without the need for any side to be specifically aligned with a preset side, thereby facilitating and simplifying the installation of the first cleaning head 2 and the second cleaning head 6.

[0056] Preferably, when the first cleaning head 2 is installed in the installation cavity 7, the top of the first cleaning head 2 is substantially flush with the top of the second cleaning head 6, so that the first cleaning head 2 and the second cleaning head 6 are substantially integrated in appearance.

[0057] In addition to the above-mentioned snap-on structure 11, other quick-release structures can be used between the first cleaning head 2 and the second cleaning head 6 to achieve detachable fixation, such as magnetic fit, screw fit, pin fit, etc. The installation of the first cleaning head 2 is achieved by arranging magnets, screws, pins and other devices in the installation cavity 7.

[0058] The first cleaning head 2 and the second cleaning head 6 are connected to the handle 1 in a detachable structure. 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, the first cleaning head 2 or the second cleaning head 6. 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 the other cleaning head is installed on the handle 1, thereby realizing the replacement of the cleaning head. Under this disassembly structure, the first cleaning head 2 is installed with a wipe by a first drive mechanism, and the second cleaning head 6 is provided with a second drive mechanism to realize the installation of the wipe. During the replacement process of the cleaning heads, the corresponding drive mechanisms are also replaced synchronously, that is, the first cleaning head 2 and the second cleaning head 6 are respectively provided with a first drive mechanism and a second drive mechanism that are independent of each other. Of course, the driving principles and structures of the first drive mechanism and the second drive mechanism may be the same or different.

[0059] Based on the detachable connection between the first cleaning head 2 and the second cleaning head 6, the second driving mechanism on the second cleaning head 6 can be coupled with or not coupled with the first driving mechanism to enable the second cleaning head 6 to install the wiper.

[0060] When a linkage cooperation 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 move, open or clamp. This method can achieve linkage by setting a connecting rod, a swing arm, a gear set and other structures between the first cleaning head 2 and the second cleaning head 6.

[0061] like Figure 5-7 In this embodiment, the linkage coordination method 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 installation cavity 7, the bottoms of the first clamping member 3 and the second clamping member 4 are each provided with a linkage hole or linkage groove 15, and the third clamping member 8 and the fourth clamping member 9 are each provided with a linkage rod 16 at the position where they are located in the installation cavity 7. When the first cleaning head 2 is installed in the installation cavity 7, each linkage rod 16 is connected to each linkage groove 15, and 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 accordingly through the connection between the linkage rod 16 and the linkage groove 15 to install and remove the wipe. In this way, the linkage coordination between the first cleaning head 2 and the second cleaning head 6 is achieved.

[0062] When the first driving mechanism and the second driving mechanism are not linked together, when the second cleaning head 6 is not installed, the first driving mechanism enables the first cleaning head 2 to install and remove the wiper; when the second cleaning head 6 is installed, the first driving mechanism does not operate, and the second driving mechanism operates to enable the second cleaning head 6 to install and remove the wiper.

[0063] Specifically, such as Figure 3 、 8 -9, the second driving mechanism includes a second push rod 17, a third connecting rod 18 and a fourth connecting rod 19, the two ends of the third connecting rod 18 are rotatably connected to the second push rod 17 and the third clamping member 8 respectively, and the two ends of the fourth connecting rod 19 are rotatably connected to the second push rod 17 and the fourth clamping member 9 respectively. The drag rod, 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 connecting rod 18 and the fourth connecting rod 19 are simultaneously driven to rotate and move, thereby simultaneously driving the third clamping member 8 and the fourth clamping member 9 to move.

[0064] The second cleaning head 6 includes a second upper plate 20 and a second lower plate 21. The middle part of the second upper plate 20 is provided with an installation cavity 7 for the first cleaning head 2 to enter partially or as a whole. The second upper plate 20 and the second lower plate 21 are provided with a second functional cavity 22 on the periphery of the installation 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.

[0065] Preferably, Figure 9-10In order to improve the clamping force of the second cleaning head 6 on the wipe, the third clamping member 8 and the fourth clamping member 9 are movably installed on the long side of the second cleaning head 6 and can be moved 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 directions of the second push rod 17 and the third clamping member 8 and the fourth clamping member 9 are perpendicular. The setting of the third connecting rod 18 and the fourth connecting rod 19 transfers the movement of the drag rod to the third clamping member 8 and the fourth clamping member 9 in different directions.

[0066] In this embodiment, the third clamping member 8 includes a third sliding section 23 and a third clamping section 24, the third sliding section 23 and the third clamping section 24 are perpendicular to each other, and 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, the fourth sliding section 25 and the fourth clamping section 26 are perpendicular to each other, and the fourth sliding section 25 extends into the second functional cavity 22 and is rotatably connected to the fourth connecting rod 19.

[0067] Since the second push rod 17 pulls the third connecting rod 18 and the fourth connecting rod 19 to move synchronously during movement, a third track 27 is provided in the second functional cavity 22 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. The third track 27 cooperates with the connecting rod or the sliding section to limit the movement of the third clamping member 8 and the fourth clamping member 9 in the above-mentioned preset direction, thereby preventing the third clamping member 8 and the fourth clamping member 9 from moving in the direction of movement of the second push rod 17. During the process of installing and removing the wipe, 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 the sliding section is limited and guided in the opposite directions by the third track 27 or by the third track 27 and the fourth track 28 respectively.

[0068] The following describes the operating principle of the second driving mechanism: the second push rod 17 is controlled to move, and one end of the third link 18 is subjected to force to move and rotate with the second push rod 17, and the other end of the third link 18 is also rotated after being subjected to 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, and the force applied to the other end of the third link 18 is blocked by the third track 27 and changes direction. The direction of the force applied to the other end of the third link 18 and the third clamping member 8 is changed to the direction in which the third track 27 extends, so that the other end of the third link 18 and the third clamping member 8 move or rotate along the third track 27 until the second driving mechanism moves to a preset maximum movable direction. The second push rod 17 is controlled to move in the opposite direction, and one end of the third connecting rod 18 moves and rotates along with the second push rod 17. The other end of the third connecting rod 18 also rotates after receiving force. 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 received by the other end of the third connecting rod 18 is blocked by the third track 27 or the fourth track 28 and changes direction. The direction of the force received by the other end of the third connecting rod 18 and the third clamping member 8 is changed to the direction in which the third track 27 or the fourth track 28 extends, so that the other end of the third connecting rod 18 and the third clamping member 8 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 are also matched in the same manner, which will not be described in detail in this embodiment.

[0069] Preferably, the third track 27 is configured as an elongated slot, with the third sliding section 23 or the rotating shaft between the third connecting rod 18 and the third sliding section 23 inserted into the third track 27, and both sides blocked and guided by the side walls of the third track 27. Of course, by adjusting the size of the third track 27 and providing a guide block on the third connecting rod 18 near the third sliding section 23, the movement and guidance of the third clamping member 8 can also be achieved.

[0070] 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 blocking walls blocking in opposite directions respectively. When the second push rod 17 moves in different directions, different blocking walls block at different positions of the third connecting rod 18 or the third sliding section 23 to play the role of track limiting guide. On the basis of this role, the two opposite side walls of the long groove can also be understood as the third track 27 and the fourth track 28 respectively.

[0071] The fourth connecting rod 19 and the fourth clamping member 9 also adopt the same structure as the third connecting rod 18 and the third clamping member 8 to cooperate with the third track 27 and / or the fourth track 28. In this embodiment, the structure of the fourth connecting rod 19, the fourth clamping member 9, the third track 27, and the fourth track 28 are not repeated.

[0072] Preferably, during normal use, the second lower plate 21 is located below the second drive mechanism and supports the linkage of the second drive mechanism. The third track 27 and / or the fourth track 28 are provided 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 rotating shafts between the third connecting rod 18 and the third sliding section 23 and the rotating shafts 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 lower plate 21 to provide position limiting guidance. Even if there is an installation gap between the second drive mechanism and the second functional cavity 22 in the upper and lower directions, the various components of the second drive mechanism always have a tendency to move downward under the action of their own gravity, and the guide blocks are always located in the matching positions of the third track 27 and the fourth track 28, thereby making the operation of the second drive mechanism smoother.

[0073] Preferably, each end of the third clamping segment 24 is provided with a third sliding segment 23. The second push rod 17 extends toward the two third sliding ends and is connected to each third sliding segment 23 via a different third connecting rod 18. This multi-point coordinated linkage method makes the force on the third clamping member 8 more balanced and the movement smoother. Similarly, each end of the fourth clamping segment 26 is provided with a fourth sliding segment 25. The second push rod 17 extends toward the two fourth sliding segments 25 and is connected to each fourth sliding segment 25 via a different fourth connecting rod 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 segment are all the same. Therefore, when the same second push rod 17 moves, the movement state and distance of the third connecting rod 18 and the fourth connecting rod 19, and the third clamping member 8 and the fourth clamping member 9 are always synchronized.

[0074] Preferably, the clamping and removal of the wipe by the third clamping member 8 and the fourth clamping member 9 are achieved by the user operating the second push rod 17, or a second elastic member 29 is provided on the second driving mechanism, and the elastic force of the second elastic member 29 is utilized to achieve the clamping or removal of the wipe 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 member and the second cleaning head 6, between the second push rod 17 and the second cleaning head 6, or between the rotating shafts, and the second elastic member 29 is utilized to achieve automatic clamping or removal of the wipe.

[0075] 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 provided 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 provided on the second push rod 17, and the fourth locking tooth 31 is provided 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 to cooperate with the limit.

[0076] Preferably, the third locking tooth 30 and the fourth locking tooth 31 are both configured as ratchet teeth, and the third locking tooth 30 and the fourth locking tooth 31 can only move to the plug-in fitting position when the third clamping member 8 and the fourth clamping member 9 move toward each other, and the third locking tooth 30 and the fourth locking tooth 31 abut against each other in the opposite direction and cannot move away, thereby keeping the third clamping member 8 and the fourth clamping member 9 in a state of clamping the wipe. In this embodiment, when the third locking tooth 30 cooperates 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 wipes of different thicknesses.

[0077] 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, so that the third locking tooth 30 and the fourth locking tooth 31 are separated from the plug-in position. Then, the second push rod 17 can be manually pushed or pulled, or the elastic force of the second elastic member 29 automatically moves the second push rod 17, and the third clamping member 8 and the fourth clamping member 9 move from the clamping state to a disassembled state away from each other, thereby releasing the wiping object. In addition to the unlocking method of pushing the pull rod or the third locking tooth 30, the unlocking method can also be achieved by pushing the fourth locking tooth 31. Specifically, a third button is provided on the second upper plate 20, 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.

[0078] In the above embodiment, the second cleaning head 6 is provided with a third functional cavity 32 directly below the mounting cavity 7, and the switch rod 13 is located in the third functional cavity 32. Each buckle 11 extends downwardly into the third functional cavity 32 to connect with the switch rod 13, and the second functional cavity 22 and the third functional cavity 32 are connected, so that the switch rod 13 enters the second functional cavity 22 laterally and connects with the first unlocking switch 12. Because the second push rod 17 needs to be connected to 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, and 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 located in the same plane, thereby reducing the overall height of the third functional cavity 32 and the second cleaning head 6. It also prevents the switch rod 13 and the second push rod 17 from sliding against each other and causing obstruction when they are installed in a stacked manner.

[0079] Preferably, Figure 8The second push rod 17 can be connected in a manner that it 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 manner that the whole is 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 make the coordinated moving path between the second push rod 17 and the third sliding section 23 shorter, it is necessary to increase the length of the third connecting rod 18, 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 in a position close to the edge of the second cleaning head 6 to make the length of the third connecting rod 18 as long as possible. At the same time, the second push rod 17, the third connecting rod 18 and the third sliding section 23 are stacked up and down to reduce the horizontal matching space among the three. When the three are close to each other to clamp the wiping object, the second push rod 17, the third connecting rod 18 and the third sliding section 23 are at least partially located on the same vertical plane. Specifically, the second push rod 17 is located at a low position as a whole and is fitted with the second lower plate 21. An upwardly extending baffle 34 is provided on the second push rod 17. Hinge holes are provided at the upper and lower positions of the baffle 34. The third connecting rod 18 is installed in the area between the two hinge holes so that the third connecting rod 18 can be The upper and lower heights do not exceed the upper and lower positions of the baffle 34. The third sliding section 23 is also hinged to the third connecting rod 18 in the same way, so that the third sliding section 23 is roughly at the same height as the third connecting rod 18. A first clamping groove 35 is provided on the side of the third connecting rod 18 close to the third sliding section 23, and hinge holes are also provided in the upper and lower directions of the ends of the first clamping groove 35. When in the state of clamping the wipe, at least part of the third sliding section 23 is accommodated in the first clamping groove 35 to reduce the lateral volume of the third connecting rod 18 and the third sliding section 23, so that the second driving mechanism as a whole is more compact in the second functional cavity 22.

[0080] Preferably, Figure 9-10 An angle is provided between the baffle 34 and the third sliding section 23 along the horizontal section, and during the movement of the second push rod 17, the third connecting rod 18 and the third clamping member 8, the angle between the baffle 34 and the third sliding section 23 always maintains the same size.

[0081] The specific structure of the second push rod 17, the fourth connecting rod 19, and the fourth clamping member 9 is the same as the structure 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 position between the second push rod 17, the third connecting rod 18, and the third clamping member 8 is arranged in a mirror image manner along the centerline of the second cleaning head 6, and the third connecting rod 18 and the fourth connecting rod 19, and the third sliding section 23 and the fourth sliding section 25 are the same length, so that the movement between the two clamping members is always synchronized and the movement distance is the same.

[0082] Preferably, both sides of the second push rod 17 are in contact with the second lower plate 21 , and the moving direction of the second push rod 17 is limited by the second lower plate 21 , and the contact of the second lower plate 21 prevents the second push rod 17 from shaking or deflecting during movement.

[0083] In this embodiment, a second clamping groove 36 is provided on the side of the third rail 27 away from the third sliding section 23. A sleeve rod 37 is provided on the third sliding section 23 and the fourth sliding section 25 at positions corresponding to the second clamping groove 36. A second elastic member 29 is installed between the two sleeve rods 37. The second clamping mechanism prevents the second elastic member 29 from elastically separating from the sleeve rod 37 when compressed or stretched, and ensures that the direction of the elastic force released by the second elastic member 29 remains aligned with the third sliding section 23 and the fourth sliding section 25. Of course, a second elastic member 29 may also be installed between each sleeve rod 37 and the second clamping groove 36.

[0084] In the above embodiment, third clamping teeth 38 are provided on both sides of the second lower plate 21, and fourth clamping teeth 39 are provided on the third clamping section 24 and the fourth clamping section 26. 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

[0085] The similarities between this embodiment and embodiment 1 will not be repeated, and only the differences will be described. The difference between this embodiment and embodiment 1 lies in the first driving structure of the first cleaning head 2.

[0086] like Figure 11-16 In this embodiment, the first driving mechanism on the first cleaning head 2 adopts a structure substantially the same as the second driving mechanism in Example 1. Specifically, the first cleaning head 2 includes a first upper plate 41 and a first lower plate 42. The handle 1 is movably connected to the top of 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 driving mechanism is installed in the first functional cavity 43. The first driving mechanism includes a first push rod 44, a first connecting rod 45 and a second connecting rod 46. The opposite ends of the first connecting rod 45 are rotatably connected to the first push rod 44 and the first clamping member 3 respectively, and the opposite 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 are synchronously rotated and moved, driving the first clamping member 3 and the second clamping member 4 to move synchronously to clamp or remove the wiping object.

[0087] 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 installation position of the first sliding section 47, the first clamping section 48, the first connecting rod 45, and the first push rod 44, and the installation method and installation 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 of the second driving mechanism in Example 1 and will not be described in detail in this embodiment. Similarly, the first lower plate 42 is also provided with a first track 51 and / or a second track 52 having 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 predetermined position and direction. The first driving mechanism is also provided with a first elastic member, the elastic force of which enables automatic removal of the wiper with the push of a button.

[0088] 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 movably connect the second cleaning head 6 and the second driving structure with the handle 1 into a whole after removing the mounting cavity 7, and the only difference is the size between the first cleaning head 2 and the second cleaning head 6.

[0089] In this embodiment, two hinge seats 53 are provided on the top of the first upper plate 41, and a hinge 14 is provided between the two hinge seats 53. The two sides of the hinge 14 are rotatably connected to the handle 1 and the hinge seat 53 respectively. The side of one of the hinge seats 53 is movably connected with a first button 54. One end of the first button 54 extends from the side of the hinge seat 53, and the other end cooperates with the first push rod 44. By pressing the first button 54 into the hinge seat 53, the push rod is driven to move, so that the first clamping member 3 and the second clamping member 4 move toward each other to clamp the wiping object.

[0090] 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, and a movable second button 57 is provided on the first upper plate 41 or the hinged seat 53. One end of the second button 57 extends from the first upper plate 41 or the hinged seat 53, and the other end is provided with a second locking tooth 56. A third elastic member is provided between the second button 57 and the first upper plate 41 or the hinged seat 53. The movement of the second button 57 can drive the second locking tooth 56 to engage with the first locking tooth 55 or separate and unlock. The elastic force of the third elastic member makes the second locking tooth 56 have a tendency to move closer to the first locking tooth 55 or maintain a state of engaging with the first locking tooth 55. There are multiple first locking teeth 55, so that the first locking structure has the function of multi-speed adjustment locking. When installing wipes of different thicknesses, the second locking tooth 56 cooperates with different first locking teeth 55 to lock.

[0091] In addition to the above structures, Figure 16, it is also possible not to set the first button 54 on the hinge seat 53, and use the first push rod 44 to extend from the side of the first cleaning head 2 to directly press and push the first push rod 44 to drive the first clamping member 3 and the second clamping member 4 to move; similarly, the second locking tooth 56 can also be replaced, and the second locking tooth 56 can be set on the first upper plate 41 or the first lower plate 42, and the second button 57 is still movably mounted on the hinge seat 53. Pressing the hinge seat 53 moves the first locking tooth 55 or the second locking tooth 56 to deform and separate from the other matching locking tooth, so that the first drive mechanism can be unlocked for operation.

[0092] Preferably, first clamping teeth 58 are provided on both sides of the first lower plate 42, and second clamping teeth 59 are provided on the first clamping section 48 and the second clamping section 50. 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

[0093] The difference between Example 3 and Examples 1 and 2 is that Example 3 adopts a different first driving mechanism.

[0094] like Figure 17-22 In this embodiment, the first cleaning head 2 includes a first upper plate 41 and a first lower plate 42, and the first upper plate 41 and the first lower plate 42 are buckled together and can be floated up and down between the first upper plate 41 and the first lower plate 42. A first functional cavity 43 is formed between the first upper plate 41 and the first lower plate 42, and the first clamping member 3 and the 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 and open in the away direction.

[0095] 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, and a fifth track 63 is provided on the upper surface of the first lower plate 42. The first sliding section 47 and the second sliding section 49 are movably mounted on the fifth track 63 and are limited in a preset moving direction by the limiting guide of the fifth track 63. 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 follow the first lower plate 42 to move downward, and the fifth elastic member 62 releases the elastic force to cause the first clamping member 3 and the second clamping member 4 to extend from the clamping opening 60.

[0096] Preferably, a limit block 64 is provided on the fifth rail 63, and the limit block 64 is located above the first clamping member 3 and the second clamping member 4, and the first clamping member 3 and the second clamping member 4 are clamped between the limit block 64 and the first lower plate 42 or the fifth rail 63, so that the first clamping member 3 and the second clamping member 4 are fixed to the first lower plate 42 in the up and down directions, so as to move up and down synchronously with the first lower plate 42.

[0097] A general cleaning head, such as the cleaning heads in Examples 1 and 2, has a clamping opening 60 on the side where the clamping member is set. If the lower plate is set to a flat plate, the height of the flange 65 of the upper plate at the position corresponding to the clamping member needs to be lowered, or even the clamping opening 60 is set in a way that the flange 65 is no longer set at this position, so that the clamping member can pass through the clamping opening 60 horizontally. The upper plate and the lower plate are fixed, 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 in an up and down floating manner. Compared with ordinary clamping members, the first clamping member 3 and the second clamping member 4 have a different movable mode. The first clamping member 3 and the second clamping member 4 can move in the up and down directions and the horizontal direction at the same time during the process of clamping or removing the wiping object. According to this movable principle, the structure of the clamping port 60 in this embodiment needs to be adjusted so that when the first upper plate 41 and the first lower plate 42 are close to or fitted together, the first clamping member 3 and the second clamping member 4 will not extend out from the horizontal clamping port 60 due to the elastic force of the fifth elastic member 62.

[0098] Specifically, the four side edges of the first upper plate 41 are provided with downwardly extending flanges 65, and the height of the flanges 65 is roughly flush with the first lower plate 42 after installation, so as to enclose the outer periphery of the first lower plate 42. The relative two sides of the first lower plate 42 in the length direction are reduced in size to form a clamping opening 60 between the flanges 65 of the first upper plate 41, and the first clamping member 3 and the second clamping member 4 are installed at the clamping opening 60 position. The horizontal outer sides of the first clamping member 3 and the second clamping member 4 are supported by the flanges 65 and cannot move outward. Only when the first lower plate 42 drives the first clamping member 3 and the second clamping member 4 to move downward and be misaligned with the flanges 65 can the fifth elastic member 62 push the first clamping member 3 and the second clamping member 4 to open outward.

[0099] In order to keep the first cleaning head 2 in a state of clamping the wipe, a third locking structure is provided on the first cleaning head 2, and the third locking structure includes a locking hook 66, which is movably mounted on the hinged seat 53 of the first upper plate 41. The locking hook 66 can change the matching 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, the limit is released from the first lower plate 42, and the first lower plate 42 can move downward.

[0100] A general cleaning head drives the driving mechanism to operate and clamp the wiping object by pressing the handle 1 downward, while the first cleaning head 2 in this embodiment can only drive the first upper plate 41 and the first lower plate 42 to move toward each other when the handle 1 is pressed downward. In order to drive the first clamping member 3 and the second clamping member 4 to automatically clamp the wiping object by being pressed by the handle 1, in this embodiment, an inclined guide is adopted between the first clamping member 3, the second clamping member 4 and the first upper plate 41, and the upward movement of the first lower plate 42 is switched to the horizontal movement of the first clamping member 3 and the second clamping member 4, thereby automatically clamping the wiping object.

[0101] Specifically, such as Figure 20-21 A first inclined surface 67 is provided on the outer side of the first clamping section 48, and a second inclined surface 68 is provided on the inner side of the flange 65 of the first upper plate 41. The first inclined surface 67 and the second inclined surface 68 are both inclined with the lower end located on the outer side and the upper end located 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 with 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.

[0102] Preferably, Figure 21 When the first clamping member 3 and the first lower plate 42 move downward to the extreme position, at least part of the first inclined surface 67 and the second inclined surface 68 still have a horizontally overlapping area, or even at least part of the first inclined surface 67 and the second inclined surface 68 still maintain a state of being in contact with each other, thereby avoiding the first inclined surface 67 and the second inclined surface 68 from being separated, and the situation where they are stuck or misaligned and cannot cooperate when moving upward.

[0103] The second clamping member 4 and the first upper plate 41 also adopt the same structure, which will not be described in detail in this embodiment.

[0104] Preferably, the first lower plate 42 is provided with a slide groove 69 below the fifth track 63, and the first sliding section 47 and the second sliding section 49 cooperate with different slide grooves 69 to limit the length range of the first clamping member 3 and the second clamping member 4 that can be opened relative to the first cleaning head 2, thereby keeping the first inclined surface 67 and the second inclined surface 68 in a position where they always overlap or fit together.

[0105] In the above embodiment, the first upper plate 41 and the first lower plate 42 are guided and moved together, and the first slide bar 70 and the second slide bar 71 of different sizes are respectively provided at the corner positions of the first upper plate 41 and the first lower plate 42. The first slide bar 70, the second slide bar 71 and the first clamping member 3, the second clamping member 4 are staggered to avoid the slide bar and the clamping member affecting each other's activities.

[0106] Preferably, the size of the first slide bar 70 is smaller than that of the second slide bar 71. The first slide bar 70 can be inserted into the second slide bar 71 and slide up and down. The lower end of the first slide bar 70 is provided with a first limiting ring 72 protruding outward, and an insert block 73 is provided above the first limiting ring 72. The side of the second slide bar 71 is provided with a deformation gap 74 extending up and down to split the second slide bar 71 in half or into more pieces. The upper end of the second slide bar 71 is provided with a second limiting ring 75 protruding inward. The limiting ring 72 and the second limiting ring 75 overlap. During the installation process, the first upper plate 41 and the first lower plate 42 are pressed up and down, and the first limiting ring 72 pushes the second limiting ring 75 to make the second slide bar 71 open toward the outer shape. The first slide bar 70 and the first limiting ring 72 can pass through the second limiting ring 75 into the second slide bar 71, and the insert block 73 is inserted into the deformation gap 74 at the corresponding position and supported by the second slide bar 71 on the side, reducing the relative shaking of the first upper plate 41 and the second upper plate 20.

[0107] In this embodiment, a fourth elastic member 61 is sleeved on the outer side of the second sliding rod 71, the first sliding section 47 and the second sliding section 49 are installed in an upper and lower stack, and the fifth elastic member 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.

[0108] Similarly, first clamping teeth 58 are provided on both sides of the first lower plate 42, and second clamping teeth 59 are provided on the first clamping section 48 and the second clamping section 50. A clamping area 5 is formed between the first clamping teeth 58 and the second clamping teeth 59 to clamp the wiping object.

[0109] 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, which then drives 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 are guided toward each other by 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 arranged components are all required to drive the movement of the first clamping member 3 and the second clamping member 4. In other words, the first driving mechanism in this embodiment includes all of the components described above. Example 4

[0110] The difference between Example 4 and Examples 1-3 is that the second clamping teeth 59 are movably connected to the clamping member.

[0111] Specifically, a first clamping jaw 76 is provided at the outer end of the first clamping member 3, and the first clamping jaw 76 is movably connected to the first clamping member 3. A sixth elastic member 77 is provided between the first clamping jaw 76 and the first clamping member 3. The first cleaning head 2 is provided with a first clamping tooth 58, and the first clamping jaw 76 is provided with a second clamping tooth 59. The first clamping member 3 can move towards or 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 to or engaged with each other, they clamp the wipe. The thickness of the wipe 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 maintain a tendency to move towards each other to clamp the wipe.

[0112] like Figure 26 The first clamping jaw 76 includes a first clamping section 48 and a first telescopic section 78. The first clamping section 48 is provided with a second clamping tooth 59. Each first clamping tooth 58 and each second clamping tooth 59 are arranged along the side of the first cleaning head 2. The first clamping section 48 can be guided and installed on the first clamping member 3 so that the first clamping tooth 58 and the second clamping tooth 59 remain parallel when the first clamping jaw 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 is fixedly connected to the first sliding section 47 or the first guide groove 79 is provided on the first sliding section 47. The first guide groove 79 is provided with a first stopper 80. The first telescopic section 78 is provided with a first telescopic hole 81. The first telescopic hole 81 is provided with a second stopper 82. The first stopper 80 is inserted into the first telescopic hole 81 for installation. The first stopper 80 and the second stopper 82 are respectively located on opposite sides of the first telescopic hole 81. The gap between the first stopper 80 and the second stopper 82 is used to install the sixth elastic member 77. The first sliding section 47 is inserted into the first guide groove 79, and the first sliding section 47 is movably limited by the inner walls of the first guide groove 79. The first telescopic hole 81, the first stop block 80 and the second stop block 82 are arranged, and the first stop block 80 and the second stop block 82 intersect to extend the length of the sixth elastic member 77 or the telescopic length of the sixth elastic member 77. The first clamping jaw 76 moves outward to drive the second stop block 82 to move outward to squeeze the sixth elastic member 77 to change the elastic force.

[0113] The operating principle of the first cleaning head 2 in this embodiment is as follows: there is a preset movable stroke between the first clamping member 3 and the first cleaning head 2 and can be positioned after moving to the position of unfolding and retracting to the end point. When clamping the wipe, the movable first clamping jaw 76 drives the flat wipe to roll up and enter the position between the first clamping teeth 58 and the second clamping teeth 59 until the first clamping teeth 58 and the second clamping teeth 59 are staggered and engaged to clamp the wipe. Due to the obstruction of the thickness of the wipe, the first clamping teeth 58 and the second clamping teeth 59 cannot continue to move closer. If the thickness of the wipe is greater than the preset clamping gap between the first clamping teeth 58 and the second clamping teeth 59, the first clamping member 3 moves to the preset locking position, and the thickness of the wipe will push the first clamping jaw 76 away from the first cleaning head 2. The elastic force of the sixth elastic member 77 pulls the first clamping jaw 76 to clamp the wipe.

[0114] According to this principle, the preset clamping gap between the first clamping teeth 58 and the second clamping teeth 59 can be set to the following two types: the first type is, Figure 23 On the lower side, the preset clamping gap between the first clamping teeth 58 and the second clamping teeth 59 is zero, that is, the first clamping teeth 58 and the second clamping teeth 59 are misaligned, fitted or pressed against each other, and the wipes of any thickness are clamped. The wipes cause the second clamping jaws 83 to move outward to clamp the wipes. In this way, the elastic force of the sixth elastic member 77 always increases the tensioning force on wipes of different thicknesses. Even if wear or a locking gap is generated between the first clamping member 3 and the first cleaning head 2 during use, the wipes can be clamped by the action of the sixth elastic member 77; the second type is, as shown in FIG. Figure 23 On the upper side, the preset clamping gap of 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 objects such as paper towels and wet wipes, the first clamping jaw 76 does not move outward and the sixth elastic member 77 does not provide a tensioning force. When clamping thick wiping objects such as rags, mops, and multi-layer paper towels, the first clamping jaw 76 moves outward and the sixth elastic member 77 provides a tensioning force.

[0115] In the above two methods, the first clamping jaw 76 can adjust the clamping gap between the first clamping teeth 58 and the second clamping teeth 59 according to the thickness of the wipes, so that different wipes are clamped stably and will not be pierced or hooked by the clamping teeth and difficult to remove.

[0116] Of course, the range of telescopic movement of the first clamping jaw 76 is determined by the size of the first cleaning head 2 and the length of the first telescopic section 78. If the size of the first cleaning head 2 is larger, the length of the first telescopic section 78 can be set to be larger, and the thickness range of the wipes that can be adapted to the telescopic movement of the first clamping jaw 76 is larger.

[0117] Preferably, the first clamping claw 76 structure on the first clamping member 3 can be correspondingly provided on the second clamping member 4 , the third clamping member 8 or the fourth clamping member 9 .
