Description

[Technical Field]

[0001] The present invention relates to the field of mops, and more particularly to a water jet cloth clamping mop. [Background technology]

[0002] Mops are a common cleaning tool used in daily life, and cloth clamp mops have been developed to facilitate the attachment and detachment of cleaning materials. These cloth clamp mops have the advantage that the cleaning materials do not need to be washed and can be disposed of after use, making them popular with consumers. Furthermore, cloth clamp mops can be used in combination with light, thin sheet-like cleaning materials commonly found in daily life, such as wet wipes, face towels, and tissue paper. This eliminates the need to purchase and use cleaning materials with specific materials, shapes, and attachment structures, and makes cleaning material readily available.

[0003] However, in the case of the cloth clamp mop, the moisture on the wipes evaporates before or during cleaning, which affects the cleaning effect, and it is very inconvenient to wet the wipes with a tap or other water source. Therefore, the function and structure of the cloth clamp mop need to be further optimized. Summary of the Invention [Problem to be solved by the invention]

[0004] One object of the present invention is to provide a water-jet cloth-holding mop that solves the above problems. [Means for solving the problem]

[0005] To achieve the above object of the invention, the invention is realized by the following technical solutions:

[0006] A water-jet cloth clamping mop includes a mop rod equipped with a water-jet device and a mop head, the water-jet device including a water-jet switch, a water tank, and a fixed base, the water tank is inserted into and attached to the fixed base, the water-jet switch controls the water tank to spray water outward, the mop head includes a first cleaning head, the first cleaning head is equipped with a first clamping member and a second clamping member, the first clamping member and the second clamping member are respectively movably attached to opposite sides of the first cleaning head, and the first clamping member and the second clamping member are driven to move by a first driving mechanism to clamp and release the wiping material. By adjusting the structure of the mop head and changing the method of attaching the wiping material, it is possible to use a water-jet mop in conjunction with wet tissues and face towels, solving the problem of the complicated washing of the wiping material in conventional water-jet mops. The clamping method allows the wiping material to be quickly attached and detached, and it can be disposed of as is after use, with the advantage that there is no need to wash the wiping material, and the cost of wet tissues and face towels is lower than that of conventional wiping materials.

[0007] Preferably, the mop head further includes a second cleaning head, the second cleaning head having a mounting cavity, the first cleaning head being receivable in the mounting cavity and removably connected to a quick-release mechanism in the mounting cavity, and the second cleaning head having a third clamping member and a fourth clamping member, the third clamping member and the fourth clamping member being moved in conjunction with each other by the first clamping member and the second clamping member, or being driven by a second driving mechanism. Conventional cloth clamping mops do not allow for adjustment of the size of the cleaning head, and require the mop head to support the cleaning material when cleaning with the cleaning material to achieve the desired effect. Therefore, if the purchased cleaning head is small, even if a large cleaning material is clamped, the cleaning area of ​​the cleaning material will not change, but will remain the area of ​​the mop head. Therefore, different sizes of cloth clamping mops must be purchased to meet different cleaning needs. The water-jet cloth clamp mop of this invention has a second cleaning head that can be detachably attached to the first cleaning head, and by adjusting the size of the mop head, the cleaning unit area of ​​the water-jet cloth clamp mop can be adjusted.Whether it is switched to the first or second cleaning head, it can still perform the function of clamping the wiping material and cleaning.

[0008] Preferably, the first drive mechanism includes a first push rod, a first link, and a second link, both ends of the first link being rotatably connected to the first push rod and the first clamping member, respectively, and both ends of the second link being rotatably connected to the first push rod and the second clamping member, respectively, so that the movement of the first push rod is controlled, and the first link and the second link move and drive the first clamping member and the second clamping member, respectively, to clamp or remove the wiping material. The mop rod and the link are driven in conjunction with each other, and by adjusting the position of the push rod, the drive mechanism can be operated by manual pushing, stepping, kicking, etc., making it more versatile and easier to assemble than a multi-link structure.

[0009] 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 during the movement of the first lower plate to clamp or remove the wipes. The first upper plate and the first lower plate press against and move the clamping structure. Compared to conventional driving mechanisms, the movement between the first upper plate and the first lower plate is part of the driving mechanism, and the clamping member is moved and removed by installing an elastic member. This eliminates the need for additional independent components to form the driving mechanism, resulting in a simpler structure and lower costs. Furthermore, the wipes can be clamped simply by pressing the handle downward, eliminating the need to bend over when installing the wipes.

[0010] Preferably, the third clamping member and the fourth clamping member extend into the mounting cavity, the first cleaning head enters the mounting cavity, the first clamping member and the second clamping member are connected to the third clamping member and the fourth clamping member, respectively, and the first driving mechanism operates to move the first clamping member and the third clamping member in the same direction and move the second clamping member and the fourth clamping member in the same direction. By installing the second cleaning head to be interlocked with the first cleaning head, the driving mechanism within the second cleaning head can be eliminated, and the first clamping member and the third clamping member are directly connected and driven, eliminating the need for a complex interlocking structure, simplifying installation and reducing costs.

[0011] Preferably, the first drive mechanism and the second drive mechanism are independent, and the second cleaning head can be used as an independent cleaning head. The second drive mechanism includes a second push rod, a third link, and a fourth link, wherein both ends of the third link are rotatably connected to the second push rod and the third clamping member, respectively, and both ends of the fourth link are rotatably connected to the second push rod and the fourth clamping member, respectively, to control movement of the second push rod, and the third link and the fourth link move the third clamping member and the fourth clamping member, respectively, to clamp or remove the wiping material. The two drive mechanisms are installed independently, and the second cleaning head can mount and remove the wiping material regardless of whether it is attached to the handle or the first cleaning head. This allows the second cleaning head to replace the first cleaning head or to be used independently by connecting it to the handle.

[0012] Preferably, the second push rod moves in a different direction from the third clamping member and the fourth clamping member, and a third rail is provided between the third link or the third clamping member and the second cleaning head, the third rail prevents the third link and the third clamping member from moving in the direction of the second push rod, and the third link rotates and moves to move the third clamping member in a direction perpendicular to the second push rod. Because the installation space and movement space within the cleaning head are limited, the movement of the second push rod can be transmitted to a clamping member in a different direction via the link, and the second push rod, the third link, and the third clamping member can be installed vertically stacked, improving space utilization.

[0013] Preferably, the second push rod, the third link, and the third clamping member are at least partially aligned in the same vertical plane, the second push rod is provided with a baffle, and an included angle is formed between the baffle and the third slide, and the included angle between the baffle and the third slide remains constant during movement of the second push rod, the third link, and the third clamping member. By stacking the second push rod, the third link, and the third clamping member, space utilization can be improved. The second push rod, the third link, and the third clamping member are positioned close to each other when clamping wipes. The baffle can support the third link and prevent rotation of the third link in the retracted position. Since the included angle between the baffle and the third slide is constant, the movement of the three members is always stable in a predetermined direction and angle, preventing shaking or malfunction of the three members.

[0014] 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, the first clamping claws are provided with second clamping teeth, and the clamping gap between the first clamping teeth and the second clamping teeth is automatically adjustable according to the thickness of the wipes. Because the first clamping claws are movably installed, even if the locking position of the locking mechanism is constant, the first clamping claws themselves can automatically adjust the tension between the two clamping teeth according to the thickness of the clamped wipes, thereby avoiding the problem of not being able to clamp thin wipes or clamping them too tightly and making them impossible to remove, or the locking mechanism being unable to lock and clamp thick wipes.

[0015] Preferably, the water injection switch is located on the top of the mop rod, the top of the water tank is sealed, and the bottom is provided with a tank cover for water supply and drainage, the tank cover is provided with a water valve for controlling drainage, the fixed base is provided with a push rod and a water storage area, the push rod and the water valve work together to keep the water tank in a state where it continuously drains water into the water storage area, the water injection switch is located on the top of the mop rod, the fixed base is provided with a water injection nozzle communicating with the water storage area, a transmission rod is provided between the water injection switch and the water injection nozzle, the transmission rod is located in a cavity within the mop rod, and the water injection switch controls the movement of the transmission rod to drive the water injection nozzle to spray water from the water storage area out. The water in the water tank is sprayed onto the ground by controlling the water spray switch at the top of the mop rod, moistening and softening the dirt on the ground, thereby improving the cleaning effect, and the wiping material can be indirectly moistened after it comes into contact with the water spray position, eliminating the need to pre-moisten the wiping material before installation and use, or to carry the entire mop to a water source to soak the wiping material during cleaning.

[0016] Preferably, an unlocking switch that engages with the fixed base is provided on the side of the water tank, the unlocking switch is located outside the fixed base, and when the unlocking switch is pressed, the water tank can be removed from the fixed base, a top cover is provided on the upper end of the water tank, the unlocking switch is attached to the top cover, the unlocking switch is provided with a first limiting portion and a second limiting portion, the fixed base and the water tank are provided with a first engaging portion and a second engaging portion, respectively, when the unlocking switch is locked, the first limiting portion and the first engaging portion engage to fix the water tank to the fixed base, and when the unlocking switch is unlocked, the first limiting portion and the second engaging portion separate, making the water tank and the fixed base removable, and the second limiting portion and the second engaging portion engage to prevent separation of the top cover and the water tank. An unlock switch is installed on the top of the water tank, and the unlock switch or part of the water tank is exposed from the fixed base. When removing the water tank, the user can grasp the exposed part of the water tank with one hand and press the unlock switch on the side with their finger to unlock it and pull the water tank upward, making operation more convenient and allowing consumers to remove the water tank with one hand. To prevent the attachment between the water tank, top cover, and unlock switch from loosening, a second limiting part and a second engaging part are installed. When the water tank is pulled upward for removal, the second limiting part and the second engaging part work together to restrict the water tank, top cover, and unlock switch in the insertion / removal direction, avoiding a situation where the unlock switch and top cover are pulled out separately but the water tank is held by the fixed base. [Effects of the Invention]

[0017] The advantages of this invention are as follows:

[0018] 1. By adjusting the mop head structure and changing the wiping material attachment method, it is possible to use the water jet mop in conjunction with wet tissues and face towels, solving the problem of the traditional water jet mop requiring complicated cleaning of the wiping material. The clamping method allows the wiping material to be quickly attached and detached, and can be disposed of as is after use, eliminating the need to wash the wiping material. This has the advantage that the cost of wet tissues and face towels is lower than that of traditional wiping materials.

[0019] 2. Conventional water-jet cloth clamp mops cannot adjust the size of the cleaning head. The water-jet cloth clamp mop of this invention has a second cleaning head that can be detachably attached to the first cleaning head, and by adjusting the size of the mop head, the cleaning unit area of ​​the water-jet cloth clamp mop can be adjusted. Whether the first or second cleaning head is switched, it can still play the role of clamping the wiping material and cleaning.

[0020] 3. By installing the second cleaning head in conjunction with the first cleaning head, the drive mechanism within the second cleaning head can be reduced, and the first clamping member and the third clamping member are directly connected and driven, eliminating the need for a complex interlocking structure, simplifying installation and reducing costs.

[0021] 4. The two drive mechanisms are installed independently, and the second cleaning head can attach and detach the wiping material regardless of whether it is attached to the handle or the first cleaning head. This allows the second cleaning head to replace the first cleaning head or to be connected to the handle and used independently.

[0022] 5. The water in the water tank is sprayed onto the ground by controlling the water spray switch at the top of the mop rod, moistening and softening the dirt on the ground, thereby improving the cleaning effect. The mop material can be indirectly moistened after it comes into contact with the water spray position, eliminating the need to pre-moisten the mop material before installation and use, or to carry the entire mop to a water source to soak the mop material during cleaning.

[0026] As shown in Figures 1 to 33, this is a water-jet cloth clamping mop, which includes a mop rod 1 equipped with a water-jet device and a mop head 2. The water-jet device includes a water-jet switch 3, a water tank 4, and a fixed base 5. The water tank 4 is inserted into and attached to the fixed base 5. The water-jet switch 3 controls the water tank 4 to spray water outward. An unlocking switch 6 that engages with the fixed base 5 is provided on the side of the water tank 4. The unlocking switch 6 is located outside the fixed base 5. The water tank 4 can be removed from the fixed base 5 by grasping the water tank 4 or the unlocking switch 6 and pressing the unlocking switch 6. The mop head 2 includes a first cleaning head 23, and a first clamping member 24 and a second clamping member 25 are provided on opposite sides of the first cleaning head 23. The first clamping member 24 and the second clamping member 25 move toward or away from each other via a first drive mechanism. The first clamping member 24 and the second clamping member 25 move away from the first cleaning head 23 to an unfolded position. Clamping areas 26 are formed between both sides of the first cleaning head 23 and the first clamping member 24 and the second clamping member 25, respectively. The unfolded first cleaning head 23 is positioned entirely above the wiping material. The first clamping member 24 and the second clamping member 25 move toward each other, driving the contacting portion of the wiping material to enter the clamping area 26. The wiping material is clamped until it is clamped by the first cleaning head 23, the first clamping member 24, and the second clamping member 25.

[0027] Specifically, the water injection switch 3 is attached to the top of the mop rod 1, the fixed base 5 is attached to the lower end of the mop rod 1, and a transmission rod 27 is movably attached within the mop rod 1, the upper and lower ends of which are connected to the water injection switch 3 and the fixed base 5, respectively. When the water injection switch 3 is pressed, the transmission rod 27 moves, driving the water tank 4 to spray water outward. A mounting cavity 29 is provided on the top of the fixed base 5, and the mounting cavity 29 has a depth parallel to the mop rod 1. The water tank 4 is inserted into and fixed within the mounting cavity 29 along the top of the fixed base 5, the side walls of the fixed base 5 surround the water tank 4, and the shape and depth of the mounting cavity 29 match the water tank 4. The cross-sectional size of the water tank 4 is smaller than the cross-sectional size of the mounting cavity 29, which makes it easy to move the water tank 4 up and down when installing and removing it.

[0028] A top cover 8 is provided on the upper end of the water tank 4, an unlock switch 6 is attached to the top cover 8, a first limiting portion 9 and a second limiting portion 10 are provided on the unlock switch 6, and a first engaging portion 11 and a second engaging portion 12 are provided on the fixed base 5 and the water tank 4, respectively, and when the unlock switch 6 is locked, the first limiting portion 9 and the first engaging portion 11 are engaged to fix the water tank 4 to the fixed base 5, and when the unlock switch 6 is unlocked, the first limiting portion 9 and the second engaging portion 12 are separated, making the water tank 4 and the fixed base 5 removable, and the second limiting portion 10 and the second engaging portion 12 are engaged to prevent separation of the top cover 8 and the water tank 4.

[0029] As shown in Figures 6 and 7, the first limiting portion 9 and the second limiting portion 10 are installed at the lower end of the unlock switch 6 and protrude outside the top cover 8, and the first limiting portion 9 and the second limiting portion 10 are installed on opposite sides of the movement direction of the unlock switch 6, respectively, and the direction and height of the first engagement portion 11 correspond to the first limiting portion 9, and the direction and height of the second engagement portion 12 correspond to the second limiting portion 10, and when the unlock switch 6 is pressed inward, the second limiting portion 10 is inserted into the second engagement portion 12, and the first limiting portion 9 and the first engagement portion 11 move away from each other, and when the water tank 4 moves up and down and enters or leaves the fixed base 5, the first engagement portion 11 does not interfere with the first limiting portion 9. In this embodiment, the entire water tank 4 is located within the fixed base 5, and only the top cover 8 and unlock switch 6 are located outside the fixed base 5. When removing the water tank 4, only the top cover 8 can be grasped. The engagement between the second limiting portion 10 and the second engaging portion 12 allows the top cover 8 and water tank 4 to be doubly restricted and fixed, preventing the top cover 8 and water tank 4 from loosening or separating. When the unlock switch 6 is in the locked position, the first unlocking portion and the first engaging portion 11 engage to restrict movement in the vertical direction, and the second limiting portion 10 and the second engaging portion 12 separate, resulting in the double lock of the unlock switch 6. As a result, the unlocking switch 6 is locked with the fixed base 5 and the water tank 4 before and after being pressed, respectively, making it easier and more stable to remove the water tank 4. Generally, when removing the water tank 4, the user can remove it by grasping the side of the water tank 4 with their fingers. By installing the unlocking switch 6 on the side of the exposed top cover 8, the water tank 4 can be pulled upwards at the same time as pressing the unlocking switch 6. Compared to the conventional tightly fitted and attached structure, removing the water tank 4 is more labor-saving and the user can remove it with one hand.

[0030] A first groove 13 is provided at the upper end of the water tank 4, and a fixing buckle 14 is provided on the top cover 8, which engages with the first groove 13 to fix and attach the top cover 8 to the water tank 4. A fixing groove 15 is provided on the side of the top cover 8 for attaching the unlocking switch 6, and the unlocking switch 6 is movably attached within the fixing groove 15 and can slide inward or outward along the fixing groove 15.

[0031] Preferably, an elastic member is further provided in the fixing groove 15, and the elastic force of the elastic member can hold the unlocking switch 6 at a position where the first restricting portion 9 and the first engaging portion 11 are engaged with each other.

[0032] In order to allow the unlocking switch 6 to move more smoothly and to prevent the unlocking switch 6 from falling off, the fixing groove 15 is provided with a guide groove 16, and the unlocking switch 6 is provided with a guide block 17, which moves within the guide groove 16 to limit the movement direction of the unlocking switch 6. Alternatively, the fixing groove 15 may be provided with a guide block 17, and the unlocking switch 6 may be provided with a guide groove 16, which moves within the guide groove 16 to limit the movement direction of the unlocking switch 6.

[0033] The top and sides of the unlock switch 6 are provided with guide grooves 16 and guide blocks 17, respectively, and the sides of the fixed groove 15 and the top plate are provided with guide grooves 16 and guide blocks 17, respectively. The two sets of guide grooves 16 and guide blocks 17 are engaged with each other to restrict and guide multiple surfaces of the unlock switch 6, making the movement of the unlock switch 6 smoother.

[0034] Preferably, the top size of the water tank 4 narrows inward to form a step, and when installed, the top cover 8 engages with the step to be supported, and a second groove 18 is further provided at the upper end of the water tank 4, and when the top cover 8 is installed, the fixing groove extends into the second groove 18.

[0035] The top of the water tank 4 is sealed, and the bottom is provided with a tank cover 19 for supplying and draining water. The tank cover 19 is provided with a water valve 20 for controlling the drainage. The fixed base 5 is provided with a push rod 21 and a water storage area. The push rod 21 and the water valve 20 work together to keep the water tank 4 continuously draining water into the water storage area.

[0036] Preferably, the water injection device further includes a water injection nozzle 22 communicating with the water storage area, and the water injection switch 3 controls the water injection nozzle 22 to inject water from the water storage area to the outside.

[0037] In this embodiment, a viewing window 24 extending vertically is provided on the side of the fixed base 5, and the water tank 4 is made of a transparent material, so that information on the water level in the water tank 4 can be displayed through the viewing window 24.

[0038] Example 1 In this embodiment, the specific structure of the first cleaning head 23 can be referred to Patent No. 202410736788.6, and will not be described again in this embodiment.

[0039] In order to change the size of the wiping material that the water-jet cloth clamping mop can clamp and the area that can be cleaned, the water-jet cloth clamping mop further includes a second cleaning head 28, the cleaning area of ​​which is different from that of the first cleaning head 23, and at the same time, the second cleaning head 28 is detachably connected to the first cleaning head 23, thereby allowing the size of the cleaning area of ​​the cleaning head connected to the mop rod 1 to be changed.

[0040] 8 to 12, the following describes the structure for detachably connecting the first cleaning head 23 and the second cleaning head 28. Specifically, the second cleaning head 28 is larger than the first cleaning head 23, and a mounting cavity 29 that fits the first cleaning head 23 is provided on the top surface of the second cleaning head 28. A quick release mechanism is provided between the first cleaning head 23 and the mounting cavity 29, allowing the first cleaning head 23 and the second cleaning head 28 to be fixedly connected and detached. A third clamping member 30 and a fourth clamping member 31 are provided on opposite sides of the second cleaning head 28, respectively. The third clamping member 30 and the fourth clamping member 31 are driven by the first clamping member 24 and the second clamping member 25, or a second driving mechanism independent of the first driving mechanism can be provided, allowing the second cleaning head 28 to clamp a larger size wiping material after installation and expand the cleaning area.

[0041] As shown in Figures 9 to 11, the first cleaning head 23 and the second cleaning head 28 are removably connected using a snap mechanism. One or more locking grooves 32 are provided on the bottom of the first cleaning head 23, and one or more upwardly protruding snaps 33 are provided on the bottom of the mounting cavity 29. A fixed connection can be achieved by engaging each snap 33 with each locking groove 32. Each snap 33 is movably installed and can be detached from each locking groove 32 after movement. The movable structure of each snap 33 can be individually controlled by installing a first unlocking switch 34, and may be connected to the same first unlocking switch 34 to be controlled in a one-touch unlocking manner.

[0042] Preferably, the first unlocking switch 34 is installed outside the mounting cavity 29 for ease of operation by the user. In this embodiment, the first unlocking switch 34 is slidably mounted on the top of the second cleaning head 28, and each snap 33 is located on the same straight line and simultaneously connected to the first unlocking switch 34 via the switch rod 35. When the first unlocking switch 34 is slid, each snap 33 slides simultaneously to change position, and the snaps 33 are separated from the locking grooves 32.

[0043] In this embodiment, both the first cleaning head 23 and the second cleaning head 28 are rectangular. To facilitate alignment between the snaps 33 and the locking grooves 32 when installing the first cleaning head 23, the locking grooves 32 are located at the center of the first cleaning head 23, or each locking groove 32 is located mirror-image of the center. The position of each snap 33 in the installation cavity 29 corresponds to the position of each locking groove 32 on the first cleaning head 23. This allows the first cleaning head 23 and the second cleaning head 28 to be aligned in the length and width directions, eliminating the need to align either side to a specific preset side, making installation of the first cleaning head 23 and the second cleaning head 28 convenient and simple.

[0044] Preferably, when the first cleaning head 23 is mounted in the mounting cavity 29, the top of the first cleaning head 23 is approximately flush with the top of the second cleaning head 28, so that the outer surfaces of the first cleaning head 23 and the second cleaning head 28 are approximately integrated.

[0045] In addition to the snap 33 structure, the detachable fastening between the first cleaning head 23 and the second cleaning head 28 can be achieved through other quick release structures such as magnetic adsorption engagement, screw engagement, pin engagement, etc., and the first cleaning head 23 can be mounted by installing a device such as a magnet, screw, pin, etc. in the mounting cavity 29.

[0046] Based on the detachable connection between the first cleaning head 23 and the second cleaning head 28, the second drive mechanism on the second cleaning head 28 can realize the attachment of a wiping material to the second cleaning head 28, with or without interlocking with the first drive mechanism.

[0047] When using the interlocking linkage structure, the first clamping member 24 and the second clamping member 25 on the first cleaning head 23 move, and the third clamping member 30 and the fourth clamping member 31 on the second cleaning head 28 move to achieve deployment or clamping. In this method, interlocking can be achieved by installing structures such as links, swing arms, and gear groups between the first cleaning head 23 and the second cleaning head 28.

[0048] As shown in FIGS. 13 to 15, in the interlocking cooperation system of this embodiment, the first clamping member 24, the second clamping member 25, the third clamping member 30, and the fourth clamping member 31 extend and move in the same direction, the inner ends of the third clamping member 30 and the fourth clamping member 31 extend into the mounting cavity 29, the bottoms of the first clamping member 24 and the second clamping member 25 are provided with interlocking holes or interlocking grooves 37, the third clamping member 30 and the fourth clamping member 31 are provided with interlocking rods 38 at the position of the mounting cavity 29, when the first cleaning head 23 is mounted in the mounting cavity 29, each interlocking rod 38 and each interlocking groove 37 engage and connect, and when the first clamping member 24 and the second clamping member 25 move, the connection between the interlocking rods 38 and the interlocking grooves 37 drives and moves the third clamping member 30 and the fourth clamping member 31 to attach or remove the wiping material. This allows for interlocking cooperation between the first cleaning head 23 and the second cleaning head 28.

[0049] When the first drive mechanism and the second drive mechanism are not linked together, if the second cleaning head 28 is not attached, the first drive mechanism enables the attachment and detachment of the wiping material to the first cleaning head 23, and if the second cleaning head 28 is attached, the first drive mechanism does not operate and the second drive mechanism operates, enabling the attachment and detachment of the wiping material to the second cleaning head 28.

[0050] Specifically, as shown in Figures 10, 16 and 17, the second drive mechanism includes a second push rod 39, a third link 40 and a fourth link 41, both ends of the third link 40 are rotatably connected to the second push rod 39 and the third clamping member 30, respectively, and both ends of the fourth link 41 are rotatably connected to the second push rod 39 and the fourth clamping member 31, respectively, and the second push rod 39, the third clamping member 30 and the fourth clamping member 31 are all movably attached to the second cleaning head 28, and while the second push rod 39 is moving, the third link 40 and the fourth link 41 are simultaneously rotated and moved, thereby simultaneously moving the third clamping member 30 and the fourth clamping member 31.

[0051] The second cleaning head 28 includes a second upper plate 42 and a second lower plate 43, and the second upper plate 42 has a mounting cavity 29 in the center for the first cleaning head 23 to partially or completely enter. The second upper plate 42 and the second lower plate 43 have a second functional cavity 44 installed around the mounting cavity 29, and the second push rod 39, the third link 40, the fourth link 41, the third clamping member 30 and the fourth clamping member 31 are all mounted within the second functional cavity 44.

[0052] Preferably, as shown in Figures 16 and 17, in order to improve the clamping force of the second cleaning head 28 on the wiping material, the third clamping member 30 and the fourth clamping member 31 are movably attached to the long sides of the second cleaning head 28 and can move along a direction perpendicular to the long sides, i.e., a direction parallel to the short sides of the second cleaning head 28, and the second push rod 39 moves along a direction parallel to the long sides, so that the movement directions of the second push rod 39, the third clamping member 30 and the fourth clamping member 31 are vertical, and by installing the third link 40 and the fourth link 41, the movement of the mop rod is transmitted to the third clamping member 30 and the fourth clamping member 31 in different directions.

[0053] In this embodiment, the third clamping member 30 includes a third sliding portion 45 and a third clamping portion 46 that are perpendicular to each other, and the third sliding portion 45 extends into the second functional cavity 44 and is rotatably connected to the third link 40, and the fourth clamping member 31 includes a fourth sliding portion 47 and a fourth clamping portion 48 that are perpendicular to each other, and the fourth sliding portion 47 extends into the second functional cavity 44 and is rotatably connected to the fourth link 41.

[0054] As the second push rod 39 moves, it pulls the third link 40 and the fourth link 41, causing them to move synchronously. To prevent the third clamping member 30 and the fourth clamping member 31 from following the second push rod 39 and moving in the same direction, a third rail 49 is provided in the second functional cavity 44, and the third rail 49 engages with a link or slide portion to limit the movement of the third clamping member 30 and the fourth clamping member 31 to the above-mentioned specified direction, preventing the third clamping member 30 and the fourth clamping member 31 from following the second push rod 39 and moving in the movement direction of the second push rod 39. When installing and removing the wiper, the second push rod 39 needs to move in two opposite directions, the third link 40 and the fourth link 41 also need to move in two opposite directions, the third clamping member 30 and the fourth clamping member 31 also need to move in two opposite directions, and the links or slides are restricted and guided in two opposite directions by the third rail 49, or are restricted and guided in opposite directions by the third rail 49 and the fourth rail 50, respectively.

[0055] The operating principle of the second drive mechanism will be described below. By controlling the movement of the second push rod 39, one end of the third link 40 receives a force and moves and rotates following the second push rod 39, while the other end of the third link 40 rotates after receiving the force. Due to the action of the third rail 49, the other end of the third link 40 cannot move in the same direction as the second push rod 39. The force applied to the other end of the third link 40 is blocked and redirected by the third rail 49, and the direction of the force applied to the other end of the third link 40 and the third clamping member 30 is redirected in the extension direction of the third rail 49. The other end of the third link 40 and the third clamping member 30 move or rotate along the third rail 49 until the second drive mechanism reaches a preset maximum movable position. When the second push rod 39 is controlled to move in the opposite direction, one end of the third link 40 moves and rotates following the second push rod 39, and the other end of the third link 40 also receives a force and rotates. Due to the action of the third rail 49 or the fourth rail 50, the other end of the third link 40 cannot move in the same direction as the second push rod 39. The force applied to the other end of the third link 40 is blocked and changed by the third rail 49 or the fourth rail 50. The direction of the force applied to the other end of the third link 40 and the third clamping member 30 is changed to the extension direction of the third rail 49 or the fourth rail 50. As a result, the other end of the third link 40 and the third clamping member 30 move or rotate along the third rail 49 or the fourth rail 50. Similarly, the second push rod 39, the fourth link 41, and the fourth clamping member 31 can be engaged in a similar manner, which will not be described again in this embodiment.

[0056] Preferably, the third rail 49 is installed as an elongated groove, and the third sliding part 45 or the rotation axis between the third link 40 and the third sliding part 45 is inserted into the third rail 49, and both sides are blocked, limited, and guided by the side walls of the third rail 49. Of course, the movement and guidance of the third clamping member 30 can be achieved by adjusting the size of the third rail 49 and installing guide blocks near the third sliding part 45 of the third link 40.

[0057] When the third rail 49 and the fourth rail 50 are installed simultaneously, the third rail 49 and the fourth rail 50 are two stop walls that block in opposite directions, and when the second push rod 39 moves along different directions, the different stop walls block at different positions of the third link 40 or the third slide portion 45, playing the role of limiting and guiding by the rails. Based on this role, the two opposing side walls of the elongated groove can also be understood as the third rail 49 and the fourth rail 50, respectively.

[0058] The fourth link 41 and the fourth clamping member 31 also cooperate with the third rail 49 and / or the fourth rail 50 using a structure similar to that of the third link 40 and the third clamping member 30, and therefore this embodiment will not repeatedly describe the structures of the fourth link 41, the fourth clamping member 31, the third rail 49, and the fourth rail 50.

[0059] Preferably, during normal use, the second lower plate 43 is located below the second drive mechanism to support its interlocking movement, the third rail 49 and / or the fourth rail 50 are mounted on the second lower plate 43, and downwardly protruding guide blocks are provided at the lower ends of the third slide portion 45 and the fourth slide portion 47, or the rotation axis between the third link 40 and the third slide portion 45 and the rotation axis between the fourth link 41 and the fourth slide portion 47 extend downward to form guide blocks that engage with the third rail 49 and the fourth rail 50 on the lower second lower plate 43 for limiting and guiding. Even if the second drive mechanism has an installation gap in the vertical direction of the second functional cavity 44, each component of the second drive mechanism will always tend to move downward due to its own gravity, and the guide blocks will always be located at the engagement positions of the third rail 49 and the fourth rail 50, thereby making the operation of the second drive mechanism smoother.

[0060] Preferably, third slide portions 45 are provided at both ends of the third clamping portion 46, and the second push rod 39 extends toward the two third slide ends and is connected to each of the third slide portions 45 via different third links 40. This interlocking engagement at multiple points improves balance of the force applied to the third clamping member 30, resulting in smoother movement. Similarly, fourth slide portions 47 are provided at both ends of the fourth clamping portion 48, and the second push rod 39 extends toward the two fourth slide portions 47 and is connected to each of the fourth slide portions 47 via different fourth links 41. In this embodiment, the lengths of the links, the positions of the rotational connections at both ends, and the lengths of the slide portions are all the same. Therefore, when the same second push rod 39 moves, the movement states and distances of the third link 40 and the fourth link 41, and the third clamping member 30 and the fourth clamping member 31 are always synchronized.

[0061] Preferably, the third clamping member 30 and the fourth clamping member 31 clamp and remove the wiping material by operating the second push rod 39 by the user, or a second elastic member 51 is installed on the second drive mechanism, and the third clamping member 30 and the fourth clamping member 31 clamp or remove the wiping material by using the elastic force of the second elastic member 51. The second elastic member 51 can be attached between the two clamping members, between the clamping member and the second cleaning head 28, between the second push rod 39 and the second cleaning head 28, or between each rotation shaft, and the use of the second elastic member 51 can realize automatic clamp or remove of the wiping material.

[0062] In this embodiment, the second cleaning head 28 is further provided with a second locking structure, which locks the third clamping member 30 and the fourth clamping member 31 in a clamping state. Specifically, the second locking structure is disposed between the second push rod 39 and the second cleaning head 28 and includes a third locking tooth 52 and a fourth locking tooth 53, the third locking tooth 52 is disposed on the second push rod 39, and the fourth locking tooth 53 is disposed on the second upper plate 42. A plurality of the fourth locking teeth 53 are provided and are equally spaced apart, and the third locking tooth 52 can be inserted between any two fourth locking teeth 53 to engage and restrict.

[0063] Preferably, both the third locking tooth 52 and the fourth locking tooth 53 are configured as ratchets, so that when the third clamping member 30 and the fourth clamping member 31 move toward each other, the third locking tooth 52 and the fourth locking tooth 53 can move to an interlocking position, and when they move in opposite directions, the third locking tooth 52 and the fourth locking tooth 53 abut against each other and cannot move apart, so that the third clamping member 30 and the fourth clamping member 31 continue to clamp the wipe. In this embodiment, when the third locking tooth 52 engages with a different fourth locking tooth 53, the distance between the third clamping member 30, the fourth clamping member 31, and the second cleaning head 28 changes to accommodate clamping wipes of different thicknesses.

[0064] To unlock the second locking mechanism, the second push rod 39 or the third locking tooth 52 is pushed in the direction of the two locking teeth, causing the third locking tooth 52 and the fourth locking tooth 53 to separate from their inserted positions. The second push rod 39 can then be manually pushed or pulled, or the second push rod 39 can be automatically moved by the elastic force of the second elastic member 51. The third clamping member 30 and the fourth clamping member 31 then move from a clamped state to a detached state, releasing the wiper. In addition to unlocking by pushing the mop rod or the third locking tooth 52, unlocking can also be achieved by pushing the fourth locking tooth 53. Specifically, a third button is provided on the second upper plate 42, and the fourth locking tooth 53 is fixed below the third button. Pressing the third button separates the fourth locking tooth 53 from the third locking tooth 52, allowing the second push rod 39 to move.

[0065] In the above embodiment, the second cleaning head 28 has a third functional cavity 54 directly below the mounting cavity 29, the switch rod 35 is located within the third functional cavity 54, each snap 33 extends downward into the third functional cavity 54 and is connected to the switch rod 35, and the second functional cavity 44 and the third functional cavity 54 are connected, and the switch rod 35 extends sideways into the second functional cavity 44 and is connected to the first unlocking switch 34. Since the second push rod 39 needs to be connected to the two third slide portions 45 and the fourth slide portion 47 at both ends, an escape hole 55 is provided in the second push rod 39, and the switch rod 35 is positioned within the escape hole 55. By positioning the second push rod 39 and the switch rod 35 on approximately the same plane, the overall height of the third functional cavity 54 and the second cleaning head 28 can be reduced, and the switch rod 35 and the second push rod 39 can be prevented from sliding against each other and becoming an obstacle when they are stacked and installed one above the other.

[0066] 15 , the second push rod 39 may be connected to be partially located in the second functional cavity 44 and partially located in the third functional cavity 54, or may be connected to be completely located in the third functional cavity 54. Because the third link 40 is rotatably connected to the end of the third slide 45, in order to shorten the path of cooperation between the second push rod 39 and the third slide 45, the length of the third link 40 needs to be increased and the rotational connection point between the third link 40 and the second push rod 39 needs to be moved away from the rotational connection point between the third link 40 and the third slide 45. Therefore, in this embodiment, the second push rod 39 is partially attached closely to the edge of the second cleaning head 28, maximizing the length of the third link 40. At the same time, by stacking the second push rod 39, the third link 40, and the third sliding part 45 one above the other, the lateral cooperation space of the three is narrowed, and when the three are close to clamping the wiper, the second push rod 39, the third link 40, and the third sliding part 45 are at least partially located in the same vertical plane. Specifically, the second push rod 39 is located in an overall low position and is installed in close contact with the second lower plate 43. The second push rod 39 is equipped with an upwardly extending baffle 56, and hinge holes are installed at both the top and bottom of the baffle 56. The third link 40 is attached to the intermediate region between the two hinge holes, so that the vertical height of the third link 40 does not exceed the vertical position of the baffle 56. The third sliding part 45 is similarly hingedly connected to the third link 40, so that the third sliding part 45 is located at approximately the same height as the third link 40. A first clamping groove 57 is provided on the side of the third link 40 that approaches the third slide portion 45, and hinge holes are also provided in the upper and lower ends of the first clamping groove 57.When the wiping material is clamped, at least a portion of the third slide portion 45 is accommodated within the first clamping groove 57, thereby reducing the lateral volume of the third link 40 and the third slide portion 45 and making the entire second drive mechanism more compact within the second functional cavity 44.

[0067] Preferably, as shown in Figures 16 and 17, an included angle is provided between the baffle 56 and the third slide portion 45 along the horizontal cross section, and the included angle between the baffle 56 and the third slide portion 45 is always the same during the movement of the second push rod 39, the third link 40, and the third clamping member 30.

[0068] The specific structures of the second push rod 39, the fourth link 41, and the fourth clamping member 31 are the same as those of the second push rod 39, the third link 40, and the third clamping member 30, and therefore will not be described again in this embodiment. The connection position between the second push rod 39, the third link 40, and the third clamping member 30 and the connection position between the second push rod 39, the fourth link 41, and the fourth clamping member 31 are installed mirror-symmetrically along the center line of the second cleaning head 28, and the third link 40 and the fourth link 41, and the third sliding part 45 and the fourth sliding part 47 have the same lengths, so that the movements of the two clamping members are always synchronized and the movement distances are the same.

[0069] Preferably, both sides of the second push rod 39 are tightly attached to the second lower plate 43, which limits the direction of movement of the second push rod 39, and the tight attachment of the second lower plate 43 prevents the second push rod 39 from shaking or shifting during movement.

[0070] In this embodiment, a second clamping groove 58 is provided on the side of the third rail 49 away from the third slide portion 45, and sleeve rods 59 are provided on the third slide portion 45 and the fourth slide portion 47 at positions corresponding to the second clamping groove 58. A second elastic member 51 is attached between the two sleeve rods 59, and the second clamping prevents the second elastic member 51 from elastically disengaging from the sleeve rod 59 when compressed or expanded, and maintains the direction of the elastic force released by the second elastic member 51 in the same straight line as the third slide portion 45 and the fourth slide portion 47. Of course, one second elastic member 51 may be attached between each sleeve rod 59 and the second clamping groove 58.

[0071] In the above embodiment, third clamping teeth 60 are provided on both sides of the second lower plate 43, and fourth clamping teeth 61 are provided on the third clamping portion 46 and the fourth clamping portion 48, and a clamping area 26 for clamping the wiping material is formed between the third clamping teeth 60 and the fourth clamping teeth 61.

[0072] Example 2 The common parts between this embodiment and the first embodiment will not be described repeatedly, and only the differences will be described. This embodiment differs from the first embodiment in the first drive structure of the first cleaning head 23.

[0073] 19 to 23, in this embodiment, the first drive mechanism on the first cleaning head 23 has substantially the same structure as the second drive mechanism in Example 1. Specifically, the first cleaning head 23 includes a first upper plate 62 and a first lower plate 63, a mop rod 1 is movably connected above the first upper plate 62, a first functional cavity 64 is provided between the first upper plate 62 and the first lower plate 63, and a first drive mechanism is attached within the first functional cavity 64, the first drive mechanism including a first push rod 65, a first link 66, and a second link 67, opposite ends of the first link 66 are rotatably connected to the first push rod 65 and the first clamping member 24, respectively, and opposite ends of the second link 67 are rotatably connected to the first push rod 65 and the second clamping member 25, respectively. By controlling the movement of the first push rod 65, the first link 66 and the second link 67 are rotated and moved in synchronization, and the first clamping member 24 and the second clamping member 25 are driven and moved in synchronization, thereby clamping or removing the wiping material.

[0074] The first clamping member 24 includes a first sliding portion 68 and a first clamping portion 69, and the second clamping member 25 includes a second sliding portion 70 and a second clamping portion 71. The attachment method and location between the first sliding portion 68, the first clamping portion 69, the first link 66, and the first push rod 65, as well as the attachment method and location between the second sliding portion 70, the second clamping portion 71, the second link 67, and the first push rod 65, are the same as those of the second drive mechanism in Example 1, and therefore will not be described again in this Example. Similarly, the first lower plate 63 is also provided with a first rail 72 and / or a second rail 73, which function similarly to the third rail 49 and the fourth rail 50, thereby limiting the movement of the two clamping members and the two links to predetermined positions and directions. The first drive mechanism is also provided with a first elastic member, the elastic force of which allows the wiper to be automatically removed by simply pressing a button once.

[0075] As can be understood, the principle and structure of the first cleaning head 23 and the first drive mechanism in this embodiment is to movably connect the second cleaning head 28 and the second drive structure to the mop rod 1 as a whole after removing the mounting cavity 29, and only the size between the first cleaning head 23 and the second cleaning head 28 is different.

[0076] In this embodiment, two hinge connection bases 74 are provided on the top of the first upper plate 62, and a hinge connection member 36 is provided between the two hinge connection bases 74. Both sides of the hinge connection member 36 are rotatably connected to the mop rod 1 and the hinge connection base 74, respectively. A first button 75 is movably connected to the side of one of the hinge connection bases 74, and one end of the first button 75 protrudes from the side of the hinge connection base 74 and the other end is interlocked with the first push rod 65. By pressing the first button 75 into the hinge connection base 74 and driving the push rod to move, the first clamping member 24 and the second clamping member 25 move toward each other and clamp the wiping material.

[0077] Preferably, the first drive mechanism is also provided with a first locking structure, which includes a first locking tooth 76 and a second locking tooth 77, the first locking tooth 76 being provided on the first push rod 65, a movable second button 78 being provided on the first upper plate 62 or the hinge connecting base 74, one end of the second button 78 protruding from the first upper plate 62 or the hinge connecting base 74 and the second locking tooth 77 being provided on the other end, and a third elastic member being provided between the second button 78 and the first upper plate 62 or the hinge connecting base 74, so that the second locking tooth 77 and the first locking tooth 76 can be inserted into each other to engage with each other or separated from each other to unlock by moving the second button 78. Due to the elastic force of the third elastic member, the second locking tooth 77 tends to move closer to the first locking tooth 76 or maintains an inserting engagement state with the first locking tooth 76. There are multiple first locking teeth 76, so that the first locking structure has a multi-stage adjustable locking function. When wipes of different thicknesses are installed, the second locking tooth 77 engages and locks with different first locking teeth 76.

[0078] 23 , the first button 75 is not installed on the hinge connection base 74, and the first push rod 65 protrudes from the side of the first cleaning head 23, allowing the first clamping member 24 and the second clamping member 25 to be moved by directly pressing the first push rod 65. Similarly, the position of the second locking tooth 77 can be changed. The second locking tooth 77 can be installed on the first upper plate 62 or the first lower plate 63, with the second button 78 still movably attached to the hinge connection base 74. When the hinge connection base 74 is pressed and moved, the first locking tooth 76 or the second locking tooth 77 is pushed out and deformed, separating it from the other engaged locking tooth, allowing the first drive mechanism to operate in an unlocked state.

[0079] Preferably, first clamping teeth 79 are provided on both sides of the first lower plate 63, and second clamping teeth 80 are provided on the first clamping portion 69 and the second clamping portion 71, and a clamping area 26 for clamping the wipe material is formed between the first clamping teeth 79 and the second clamping teeth 80.

[0080] Example 3 The third embodiment differs from the first and second embodiments in that a different first drive mechanism is used in the third embodiment.

[0081] As shown in Figures 24 to 29, in this embodiment, the first cleaning head 23 includes a first upper plate 62 and a first lower plate 63, which are engaged and connected vertically, and which are arranged to be movable in the vertical direction. A first functional cavity 64 is formed between the first upper plate 62 and the first lower plate 63, and the first clamping member 24 and the second clamping member 25 are movably attached within the first functional cavity 64. A fourth elastic member 82 and a fifth elastic member 83 are provided within the first functional cavity 64, and the elastic force of the fourth elastic member 82 causes the first upper plate 62 and the first lower plate 63 to move away from each other, and the elastic force of the fifth elastic member 83 causes the first clamping member 24 and the second clamping member 25 to move away from each other and unfold.

[0082] Specifically, a clamping opening 81 is provided between the first upper plate 62 and the first lower plate 63, through which the first clamping member 24 and the second clamping member 25 pass, a fifth rail 84 is provided on the upper surface of the first lower plate 63, the first slide portion 68 and the second slide portion 70 are movably attached to the fifth rail 84 and are restricted in a predetermined movement direction by the restricting guide of the fifth rail 84, and in the process of the first upper plate 62 and the first lower plate 63 moving apart, the first clamping member 24 and the second clamping member 25 move downward following the first lower plate 63, the fifth elastic member 83 releases its elastic force, and the first clamping member 24 and the second clamping member 25 protrude from the clamping opening 81.

[0083] Preferably, a positioning block 85 is provided on the fifth rail 84, and the positioning block 85 is located above the first clamping member 24 and the second clamping member 25, and clamps the first clamping member 24 and the second clamping member 25 between the positioning block 85 and the first lower plate 63 or the fifth rail 84, thereby fixing the first clamping member 24 and the second clamping member 25 to the first lower plate 63 in the vertical direction and moving upward and downward in synchronization with the first lower plate 63.

[0084] In typical cleaning heads, such as the cleaning heads in Examples 1 and 2, a clamping opening 81 is provided on the side where the clamping member is installed, and if the lower plate is flat, the clamping member can pass through the clamping opening 81 laterally. The upper plate needs to lower the height of the flange 86 at the position corresponding to the clamping member, or even install the clamping opening 81 so that the flange 86 is not installed at that position. The upper and lower plates are fixed to each other, and the clamping member always moves on the same horizontal plane and is always flush with the clamping opening 81. The first upper plate 62 and the first lower plate 63 in this embodiment are connected to be able to float in the vertical direction. Compared with ordinary clamping members, the movement manner of the first clamping member 24 and the second clamping member 25 is different, and the first clamping member 24 and the second clamping member 25 can move up and down and horizontally at the same time when clamping or removing the wiping material. Based on this movement principle, the structure of the clamping opening 81 in this embodiment needs to be adjusted so that when the first upper plate 62 and the first lower plate 63 approach or come into close contact with each other, the first clamping member 24 and the second clamping member 25 do not protrude laterally from the clamping opening 81 due to the elastic force of the fifth elastic member 83.

[0085] Specifically, downwardly extending flanges 86 are provided on the four sides of the first upper plate 62, and the height of the flanges 86 is approximately flush with that of the first lower plate 63 after installation, surrounding the outer periphery of the first lower plate 63 and reducing the size of both opposing sides of the first lower plate 63 in the longitudinal direction. A clamping opening 81 is formed between the flanges 86 of the first upper plate 62, and the first clamping member 24 and the second clamping member 25 are attached to the clamping opening 81. The horizontal outer sides of the first clamping member 24 and the second clamping member 25 abut against the flanges 86 and cannot move outward to deploy. Only when the first lower plate 63 moves the first clamping member 24 and the second clamping member 25 downward and misaligns them with the flanges 86 can the fifth elastic member 83 push the first clamping member 24 and the second clamping member 25 to deploy outward.

[0086] In order to keep the first cleaning head 23 clamping the wiping material, the first cleaning head 23 is provided with a third locking structure, which includes a locking hook 87 movably attached to the hinge connection base 74 of the first upper plate 62, and the engagement relationship with the first lower plate 63 can be changed by moving the locking hook 87. When the locking hook 87 is hooked on the first lower plate 63, the first lower plate 63 cannot move downward relative to the upper plate, and when the locking hook 87 moves, the restriction on the first lower plate 63 is released, and the first lower plate 63 can move downward.

[0087] In a typical cleaning head, the mop rod 1 is pressed downward to activate the drive mechanism and clamp the wiping material, but in the first cleaning head 23 of this embodiment, when the mop rod 1 is pressed downward, the first upper plate 62 and the first lower plate 63 are simply driven to move closer to each other. In order to drive the first clamping member 24 and the second clamping member 25 by the pressure of the mop rod 1 and automatically clamp the wiping material, in this embodiment, the first clamping member 24, the second clamping member 25 and the first upper plate 62 use a sloped guide system, and the upward movement of the first lower plate 63 is converted into horizontal movement of the first clamping member 24 and the second clamping member 25, thereby automatically clamping the wiping material.

[0088] Specifically, as shown in Figures 27 and 28, a first inclined surface 88 is provided on the outside of the first clamping portion 69, and a second inclined surface 89 is provided on the inside of the flange 86 of the first upper plate 62, and both the first inclined surface 88 and the second inclined surface 89 are inclined so that their lower ends are outward and their upper ends are inward, and while the first clamping member 24 is being deployed and clamped, the first inclined surface 88 and the second inclined surface 89 are always in close contact with each other, so that when the first lower plate 63 moves upward, the first inclined surface 88 and the second inclined surface 89 immediately enter their engagement positions and push the first clamping member 24 away, moving it.

[0089] Preferably, as shown in FIG. 28, when the first clamping member 24 and the first lower plate 63 move downward to their limit positions, at least a portion of the first inclined surface 88 and the second inclined surface 89 still have an area where they overlap horizontally, or at least a portion of the first inclined surface 88 and the second inclined surface 89 still maintain a state of tight contact, thereby avoiding a situation in which the first inclined surface 88 and the second inclined surface 89 separate and become unable to engage and interlock due to malfunction or misalignment when moving upward.

[0090] The second clamping member 25 and the first upper plate 62 also have the same structure, and therefore will not be described repeatedly in this embodiment.

[0091] Preferably, the first lower plate 63 has a slide groove 90 below the fifth rail 84, and the first slide portion 68 and the second slide portion 70 are engaged with different slide grooves 90 to limit the length range over which the first clamping member 24 and the second clamping member 25 can be deployed relative to the first cleaning head 23, thereby maintaining the first inclined surface 88 and the second inclined surface 89 in a position where they always overlap or are in close contact with each other.

[0092] In the above embodiment, the first upper plate 62 and the first lower plate 63 are guided and move in engagement, and the first upper plate 62 and the first lower plate 63 have first sliding rods 91 and second sliding rods 92 of different sizes installed at each corner, and the first sliding rods 91, the second sliding rods 92 and the first clamping member 24, the second clamping member 25 are arranged at offset positions from each other to avoid mutual influence on the movement of the sliding rods and the clamping members.

[0093] Preferably, the size of the first sliding rod 91 is smaller than the size of the second sliding rod 92, and the first sliding rod 91 can be inserted into the second sliding rod 92 and slide up and down. The lower end of the first sliding rod 91 is provided with a first limiting ring 93 protruding outward, and an inserting block 94 is provided above the first limiting ring 93. The side of the second sliding rod 92 is provided with a deformed slit 95 extending up and down to divide the second sliding rod 92 into two or more pieces. The upper end of the second sliding rod 92 is provided with a deformed slit 95 protruding inward. The first limiting ring 93 and the second limiting ring 96 overlap each other and press the first upper plate 62 and the first lower plate 63 upward and downward during installation. The first limiting ring 93 presses the second limiting ring 96, causing the second sliding rod 92 to deform outward and expand. The first sliding rod 91 and the first limiting ring 93 can pass through the second limiting ring 96 and enter the second sliding rod 92. The inserting block 94 is inserted into the corresponding deformation slit 95 to support the second sliding rod 92 on the side and reduce the shaking when the first upper plate 62 and the second upper plate 42 approach each other.

[0094] In this embodiment, a fourth elastic member 82 is fitted on the outside of the second slide rod 92, the first slide portion 68 and the second slide portion 70 are mounted in a stacked manner one above the other, and a fifth elastic member 83 is mounted between the first slide portion 68 and the second slide portion 70 to directly and synchronously control the movement of the first clamping member 24 and the second clamping member 25.

[0095] Similarly, first clamping teeth 79 are provided on both sides of the first lower plate 63, and second clamping teeth 80 are provided on the first clamping portion 69 and the second clamping portion 71, and a clamping area 26 for clamping the wiping material is formed between the first clamping teeth 79 and the second clamping teeth 80.

[0096] In the above embodiment, the movement of the first clamping member 24 and the second clamping member 25 is driven by the fifth elastic member 83 after the fourth elastic member 82 drives the first lower plate 63 to move, and during clamping, the first clamping member 24 and the second clamping member 25 move closer to each other under the guidance of the first inclined surface 88 and the second inclined surface 89. The first upper plate 62, the first lower plate 63, the fourth elastic member 82, the fifth elastic member 83, the first inclined surface 88, the second inclined surface 89, and other correspondingly installed members can all be understood to be members necessary to drive and move the first clamping member 24 and the second clamping member 25, i.e., the first driving mechanism in this embodiment includes each of the members described above.

[0097] Example 4 The fourth embodiment differs from the first to third embodiments in that the second clamping teeth 80 and the clamping member are movably connected.

[0098] Specifically, a first clamping claw 97 is provided at the outer end of the first clamping member 24, the first clamping claw 97 is movably connected to the first clamping member 24, a sixth elastic member 98 is provided between the first clamping claw 97 and the first clamping member 24, a first clamping tooth 79 is provided on the first cleaning head 23, and a second clamping tooth 80 is provided on the first clamping claw 97, and the first clamping member 24 is movably moved toward or away from the first cleaning head 23. The sixth elastic member 98 can move in the vertical direction, thereby changing the distance between the first clamping tooth 79 and the second clamping tooth 80. When the first clamping tooth 79 and the second clamping tooth 80 approach or mesh with each other, the wiping material is clamped. The clamping distance between the first clamping tooth 79 and the second clamping tooth 80 changes depending on the thickness of the wiping material. Due to the elastic force of the sixth elastic member 98, the first clamping tooth 79 and the second clamping tooth 80 tend to move closer to each other, thereby clamping the wiping material.

[0099] As shown in Figure 31, the first clamping claw 97 includes a first clamping portion 69 and a first extendable portion 99, and the first clamping portion 69 is provided with a second clamping tooth 80, and each of the first clamping teeth 79 and each of the second clamping teeth 80 is arranged extending along the side of the first cleaning head 23, and the first clamping portion 69 is guidably attached to the first clamping member 24, thereby maintaining the first clamping tooth 79 and the second clamping tooth 80 parallel to each other when the first clamping claw 97 moves. Specifically, the first clamping member 24 includes a first sliding portion 68 and a first guide groove 100, the first guide groove 100 is fixedly connected to the first sliding portion 68, or the first guide groove 100 is installed on the first sliding portion 68, a first stopper block 101 is provided in the first guide groove 100, a first telescopic portion 99 is provided with a first telescopic hole 102, a second stopper block 103 is provided in the first telescopic hole 102, the first stopper block 101 is inserted into and attached to the first telescopic hole 102, the first stopper block 101 and the second stopper block 103 are respectively located on opposite sides of the first telescopic hole 102, and the gap between the first stopper block 101 and the second stopper block 103 is used to attach the sixth elastic member 98. The first sliding portion 68 is inserted into the first guide groove 100, and the inner walls of the first guide groove 100 restrict the movement of the first sliding portion 68. The first telescopic hole 102, the first retaining block 101 and the second retaining block 103 are installed such that the first retaining block 101 and the second retaining block 103 intersect to lengthen the length of the sixth elastic member 98 or the telescopic length of the sixth elastic member 98. The first clamping claw 97 moves outward, causing the second retaining block 103 to move outward and compress the sixth elastic member 98 to change the elastic force.

[0100] The principle of use of the first cleaning head 23 in this embodiment is as follows: There is a preset movement stroke between the first clamping member 24 and the first cleaning head 23, and the first clamping member 24 is positioned after moving to the deployed position or retracting to the end position. When clamping a wiping material, the movable first clamping claw 97 drives the flatly laid wiping material to lift it up and enters a position between the first clamping teeth 79 and the second clamping teeth 80, which then mesh with each other in a misaligned position to clamp the wiping material. The first clamping tooth 79 and the second clamping tooth 80 cannot move closer together due to the thickness of the wiping material, and when the thickness of the wiping material is greater than the predetermined clamping gap between the first clamping tooth 79 and the second clamping tooth 80, the first clamping member 24 moves to a predetermined locking position, and the thickness of the wiping material pushes the first clamping claw 97 to move away from the first cleaning head 23, and the elastic force of the sixth elastic member 98 pulls the first clamping claw 97 to clamp the wiping material.

[0101] Based on this principle, the predetermined clamping gap between the first clamping teeth 79 and the second clamping teeth 80 can be set to one of the following two types: First, as shown in the lower part of Figure 30, the predetermined clamping gap between the first clamping teeth 79 and the second clamping teeth 80 is zero, that is, the first clamping teeth 79 and the second clamping teeth 80 are misaligned and in close contact or abutting each other. When clamping a wiping material of a given thickness, the second clamping claws 104 move outward and expand to clamp the wiping material. In this manner, the elastic force of the sixth elastic member 98 constantly increases the tension for wiping materials of different thicknesses. This allows the sixth elastic member 98 to clamp the wiping material even if wear or a locking gap occurs between the first clamping member 24 and the first cleaning head 23. Second, as shown in the upper part of Figure 30, the predetermined clamp gap between the first clamping tooth 79 and the second clamping tooth 80 is set according to the thickness of ordinary paper towels and wet tissues available on the market. When clamping thin wiping materials such as paper towels and wet tissues, the first clamping claw 97 does not move outward and the sixth elastic member 98 does not provide tension. When clamping thick wiping materials such as dustcloths, mop cloths, and multi-layered paper towels, the first clamping claw 97 moves outward and the sixth elastic member 98 provides tension.

[0102] In the above two methods, the first clamping claw 97 adjusts the clamping gap between the first clamping tooth 79 and the second clamping tooth 80 according to the thickness of the wiping material, so that different wiping materials can be stably clamped without being pierced or caught by the clamping teeth, making it easy to remove.

[0103] Of course, the range of extension and retraction movement of the first clamping claw 97 can be determined by the size of the first cleaning head 23 and the length of the first extension part 99; the larger the size of the first cleaning head 23, the longer the length of the first extension part 99 can be set, and the longer the range of wiping material thickness that is compatible with the extension and retraction movement of the first clamping claw 97 becomes.

[0104] Preferably, the first clamping claw 97 structure on the first clamping member 24 may be installed corresponding to the second clamping member 25, the third clamping member 30, or the fourth clamping member 31.

[0105] Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still amend the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features thereof, and any amendments, equivalent substitutions, improvements, etc. made in accordance with the spirit and principle of the present invention shall all fall within the protection scope of the present invention.
