Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0038] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0039] Reference Figures 1 to 9An embodiment of the present invention provides a mopping device, which can be a mop for mopping the floor or a mop for wiping other objects, such as a glass wiper for wiping glass, a wall wiper for wiping walls, etc. The mopping device includes: a base plate 1, the base plate 1 includes a first edge 1a; a clamping unit 2, the clamping unit 2 is opposite to the first edge 1a, and the clamping unit 2 is slidably connected to the base plate 1 so that the clamping unit 2 can move toward and away from the first edge 1a. The clamping unit 2 moves toward the first edge 1a to clamp a sheet-like cleaning member (not shown in the figure), and the clamping unit 2 moves away from the first edge Moving in the direction of 1a can loosen the sheet cleaning piece, where the sheet cleaning piece can be any item that can be used to remove dirt, including a cleaning cloth, disposable cleaning paper, etc. A first connecting portion 23 is provided on the clamping unit 2; a locking unit 7, the locking unit 7 is movably connected to the substrate 1 so that the locking unit 7 can move to a locking position and an unlocking position within the plane where the substrate 1 is located. When the locking unit 7 moves to the locking position, the locking unit 7 can be connected to the first connecting portion 23 on the clamping unit 2 in the clamping state; when the locking unit 7 moves to the unlocking position, the locking unit 7 can be separated from the first connecting portion 23 on the clamping unit 2 in the clamping state.

[0040] The mopping device provided by the embodiment of the present invention comprises a base plate 1 including a first edge 1a, a clamping unit 2 opposite to the first edge 1a, and a sliding connection between the clamping unit 2 and the base plate 1, so that the clamping unit 2 can move in a direction close to and away from the first edge 1a, and the clamping unit 2 can move in a direction close to the first edge 1a to clamp the sheet cleaning member, and can move in a direction away from the first edge 1a to release the sheet cleaning member, and a first connecting portion 23 is provided on the clamping unit 2, and a locking unit 7 is movably connected to the base plate 1, which can be a sliding connection or a rotating connection, so that the locking unit 7 can move in the plane where the base plate 1 is located to the locking position. The locking unit 7 has a fixed position and an unlocked position. When the locking unit 7 moves to the locked position, the locking unit 7 can connect with the first connecting portion 23 on the clamping unit 2 in the clamped state, thereby fixing the clamping unit 2 in the clamped state. When the locking unit 7 moves to the unlocked position, the locking unit 7 can separate from the first connecting portion 23 on the clamping unit 2 in the clamped state, thereby allowing the clamping unit 2 to release the sheet-like cleaning member. That is, the locking unit 7 in the mopping device provided by the embodiment of the present invention is directly connected to the first connecting portion 23 on the clamping unit 2, so there is no need to set an intermediate piece, thereby reducing parts and simplifying the structure, which is beneficial to actual production. The specific form of the first connecting portion 23 is not limited here, as long as it can achieve connection with the locking unit 7. In the example shown in the figure, the first connecting portion 23 is a hook, and the locking unit 7 also includes a hook, and the two hooks are hooked together.

[0041] Reference Figure 2 and Figure 5The clamping unit 2 includes a clamping strip 24 extending along the first edge 1a. The plurality of first connecting portions 23 are arranged along the length of the clamping strip 24. The locking unit 7 includes a push rod 71 slidably connected to the base plate 1. The push rod 71 is provided with a plurality of second connecting portions 72 along its length. When the push rod 71 moves to the locked position, the plurality of second connecting portions 72 can be connected one-to-one with the plurality of first connecting portions 23. Compared to a system with only one set of interconnected first and second connecting portions 23 and 72, this embodiment can lock the clamping strip 24 at different positions along its length, thereby preventing the clamping strip 24 from tilting or tilting. When the push rod 71 moves to the unlocked position, the plurality of second connecting portions 72 can be separated from the corresponding first connecting portions 23, thereby unlocking the clamping strip 24. The plurality of first connecting portions 23 are connected by a third connecting rod P, making the structure of the clamping unit 2 more reliable and less prone to deformation.

[0042] Preferably, the push rod 71 is arranged along the extension direction of the first edge 1a. Compared with the push rod 71 being arranged obliquely relative to the first edge 1a, this embodiment can reduce the space occupied by the push rod 71 in the extension direction of the second edge of the substrate 1. Therefore, the size of the substrate 1 along the extension direction of the second edge can be made smaller, thereby reducing the volume of the mopping device.

[0043] Furthermore, a first elastic member 73 is provided between the substrate 1 and the push rod 71 or the second connecting portion 72. Specifically, the first elastic member 73 can abut against the substrate 1 at one end and abut against the push rod 71 or the second connecting portion 72 at the other end. When it is necessary to unlock the clamping strip 24, force can be applied to the push rod 71 to move the push rod 71 from the locked position to the unlocked position. The movement of the push rod 71 from the locked position to the unlocked position can gradually squeeze the first elastic member 73 into a compressed state. When the force applied to the push rod 71 is removed, the push rod 71 can be reset from the unlocked position to the locked position under the action of the elastic restoring force of the first elastic member 73.

[0044] Since the push rod 71 is thin and the force-bearing area is small, it is inconvenient to apply force to the push rod 71. Therefore, in this embodiment, a pressure block 74 is set at one end of the push rod 71. Pressing the pressure block 74 can drive the push rod 71 to move from the locked position to the unlocked position. The force-bearing area on the pressure block 74 is larger, making it more convenient to apply force.

[0045] In some embodiments, a force-applying portion (not shown in the figure) that can slide along the length direction of the vertical pole can also be provided on the vertical pole of the mopping device. When in use, the base plate 1 is flipped to a position basically parallel to the vertical pole, and then force is applied to the locking unit 7 through the force-applying portion, so that the locking unit 7 moves to the locking position and the unlocking position within the plane where the base plate 1 is located. Specifically, force can be applied to the push rod 71 or the pressure block 74 through the force-applying portion, so that direct contact with the locking unit 7 by hand can be avoided, thereby avoiding the problem of dirtying the hands.

[0046] Reference Figures 3 to 5 , the substrate 1 also includes a second edge 1b adjacent to the first edge 1a; the wiping device also includes a driving unit 3, which is slidably connected to the substrate 1 so that the driving unit 3 can move in the direction close to and away from the second edge 1b. For example, a sliding groove N is provided on the substrate 1, and the driving unit 3 slides in the sliding groove N. The driving unit 3 moves in the direction close to the second edge 1b to drive the clamping unit 2 to move in the direction close to the first edge 1a, thereby clamping the sheet cleaning member. The driving unit 3 moves in the direction away from the second edge 1b to move the clamping unit 2 in the direction away from the first edge 1a, thereby loosening the sheet cleaning member. Therefore, when installing the sheet cleaning member of the wiping device in this embodiment, the user can first install the substrate 1 The flaky cleaning member is placed on the flaky cleaning member, and then force is applied to the driving unit 3 to move the driving unit 3 in the direction close to the second edge 1b. The driving unit 3 can drive the clamping unit 2 to move in the direction close to the first edge 1a, thereby clamping the flaky cleaning member, and completing the installation of the flaky cleaning member; and when removing the flaky cleaning member, the driving unit 3 can be moved in the direction away from the second edge 1b, so that the clamping unit 2 can be moved in the direction away from the first edge 1a, thereby loosening the flaky cleaning member, and completing the removal of the flaky cleaning member; it can be seen that the mopping device in this embodiment only requires the user to perform the operation of "applying force to the driving unit 3" when installing the flaky cleaning member, so the operation process is relatively simple, thereby improving the user experience.

[0047] In addition, since the driving unit 3 moves in the direction approaching and away from the second edge 1b, there is no need to reserve too much space for the driving unit 3 to move in the extension direction of the second edge 1b. In this way, the size of the substrate 1 along the extension direction of the second edge 1b can be made smaller, thereby reducing the volume of the mopping device.

[0048] In the first embodiment of the present invention, referring to Figure 7The clamping unit 2 is provided with a first rack 21 along its own moving direction, the driving unit 3 is provided with a second rack 31 along its own moving direction, and the base plate 1 is provided with a gear 11, which is engaged with the first rack 21 and the second rack 31. Thus, the driving unit 3 moves in the direction close to the second edge 1b, which drives the second rack 31 to move in the direction close to the second edge 1b, and then drives the gear 11 to rotate in the direction indicated by the arrow x. The gear 11 rotates in the direction indicated by the arrow x to drive the first rack 21 in the direction close to the first edge 1a. The driving unit 3 moves in the direction away from the second edge 1b, thereby driving the clamping unit 2 to move toward the first edge 1a until the sheet-like cleaning member is clamped; the driving unit 3 moves in the direction away from the second edge 1b, thereby driving the second rack 31 to move in the direction away from the second edge 1b, thereby driving the gear 11 to rotate in the opposite direction indicated by the arrow x, and the gear 11 rotates in the opposite direction indicated by the arrow x, thereby driving the first rack 21 to move in the direction away from the first edge 1a, thereby driving the clamping unit 2 to move in the direction away from the first edge 1a until the sheet-like cleaning member is released.

[0049] In the second embodiment of the present invention, referring to Figure 8 The clamping unit 2 is provided with a first inclined surface 22 inclined relative to its own moving direction. The first inclined surface 22 includes an inner end 22a and an outer end 22b. The inner end 22a is the end of the first inclined surface 22 close to the center of the substrate 1, and the outer end 22b is the end of the first inclined surface 22 away from the center of the substrate 1. The distance between the inner end 22a of the first inclined surface 22 and the second edge 1b is greater than the distance between the outer end 22b of the first inclined surface 22 and the second edge 1b. The driving unit 3 includes a first pushing portion 32. The driving unit 3 can move in the direction close to the second edge 1b by pushing the first inclined surface 22 through the first pushing portion 32. In this way, the first inclined surface 22 can move in the direction close to the first edge 1a, thereby driving the clamping unit 2 to move in the direction close to the first edge 1a until the sheet-like cleaning member is clamped. The first pushing portion 32 in this embodiment can be any structure that can push the first inclined surface 22. The specific form is not limited. For example, the first pushing portion 32 can be a protrusion, or the first pushing portion 32 can also be Figure 8 The inclined surface structure shown matches the first inclined surface 22, so that the driving force on the first inclined surface 22 is more uniform, thereby making the first inclined surface 22 and the clamping unit 2 move more smoothly toward the first edge 1a.

[0050] On the basis of the above embodiment, further, the clamping unit 2 is provided with a second inclined surface (shown in the figure) inclined relative to its own moving direction, and the second inclined surface can be arranged opposite to the first inclined surface 22, and the second inclined surface includes an inner end and an outer end, the inner end is the end of the second inclined surface close to the center of the substrate 1, and the outer end is the end of the second inclined surface away from the center of the substrate 1, and the distance between the inner end of the second inclined surface and the second edge 1b is greater than the distance between the outer end of the second inclined surface and the second edge 1b, and the driving unit 3 also includes a second pushing portion (shown in the figure), and the driving unit 3 can move in the direction away from the second edge 1b by pushing the second inclined surface through the second pushing portion, so that the second inclined surface can move in the direction away from the first edge 1a, thereby driving the clamping unit 2 to move in the direction away from the first edge 1a until the sheet cleaning member is released. Similarly, the second pushing portion in this embodiment can be any structure that can push the second inclined surface, and the specific form is not limited. For example, the second pushing portion can be a protrusion, and the second pushing portion can also be a slope structure. The slope structure matches the second inclined surface, so that the pushing force on the second inclined surface is more uniform, thereby making the second inclined surface and the clamping unit 2 move more smoothly in the direction away from the first edge 1a.

[0051] In the third embodiment of the present invention, referring to Figure 2 and Figure 5 The wiping device also includes a first connecting rod 4, a first end 4a of the first connecting rod 4 is rotatably connected to the driving unit 3, and a second end 4b of the first connecting rod 4 is rotatably connected to the clamping unit 2. The driving unit 3 moves in a direction close to the second edge 1b, which can drive the second end 4b of the first connecting rod 4 to swing around the first end 4a of the first connecting rod 4 toward the inner side of the substrate 1, thereby driving the clamping unit 2 to move in a direction close to the first edge 1a until the sheet-like cleaning element is clamped.

[0052] In the fourth embodiment of the present invention, referring to Figure 9 The wiping device also includes a second connecting rod 5, a first end 5a of the second connecting rod 5 is rotatably connected to the driving unit 3, and a second end 5b of the second connecting rod 5 is slidably connected to the clamping unit 2. A guide structure 5c is provided on the base plate 1. The driving unit 3 moves in a direction close to the second edge 1b, which can drive the second end 4b of the second connecting rod 5 to slide along the guide structure 5c toward the inner side of the base plate 1, thereby driving the clamping unit 2 to move in a direction close to the first edge 1a until the sheet-like cleaning element is clamped.

[0053] In order to further simplify the user's operation process, refer to Figure 2 and Figure 5In this embodiment, a second elastic member 6 is disposed between the clamping unit 2 and the base plate 1. The clamping unit 2 moves toward the first edge 1a, gradually squeezing the second elastic member 6 into a compressed state. The driving unit 3 moves away from the second edge 1b, allowing the clamping unit 2 to move away from the first edge 1a under the elastic restoring force of the second elastic member 6. This allows the user to release the sheet-like cleaning member from the clamping unit 2 without applying force to the driving unit 3 or the clamping unit 2, further simplifying the user's operation. Both the first elastic member 73 and the second elastic member 6 may be springs.

[0054] There are preferably two clamping units 2, and the two clamping units 2 are respectively arranged on opposite sides of the substrate 1. At this time, the substrate 1 includes two first edges 1a arranged opposite to each other, and the two clamping units 2 are opposite to the two first edges 1a one by one. A second elastic member 6 is provided between each clamping unit 2 and the substrate 1, and a strip limiting plate 12 is provided on the substrate 1 corresponding to each second elastic member 6. The strip limiting plate 12 is bent to form a slot with an opening facing the corresponding second elastic member 6, and one end of the second elastic member 6 is inserted into the corresponding slot, and the other end abuts against the corresponding clamping unit 2; the slot formed by the bending of the strip limiting plate 12 can fix the corresponding end of the second elastic member 6 more firmly, preventing the corresponding end of the second elastic member 6 from moving in the extension direction of the first edge 1a and the extension direction of the second edge 1b; it should be noted that the strip limiting plate 12 in this embodiment is bent to form a slot, and the slot can be arc-shaped as a whole, that is, the slot wall and the slot bottom have a smooth transition, or it can be Figure 2 The groove wall shown in the figure is perpendicular to the groove bottom. When the groove wall of the card slot is perpendicular to the groove bottom, the groove wall can prevent the second elastic member 6 from bending during compression, thereby better fixing the second elastic member 6.

[0055] Furthermore, the two card slots with opposite opening directions are located at different positions in the extension direction of the first edge 1a, and the groove walls of the two card slots with opposite opening directions are close to each other, thereby making the two strip limit plates 12 connected as one. In this way, the two strip limit plates 12 can be formed as one piece during production, thereby facilitating production.

[0056] Reference Figure 6The base plate 1 includes a bottom plate 13 and a cover plate 14. The upper surface of the bottom plate 13 is provided with a guide slope 131 for guiding the clamping unit 2. The end of the guide slope 131 away from the first edge 1a is higher than the end of the guide slope 131 closer to the first edge 1a. As a result, the height of the clamping unit 2 gradually decreases as it moves away from the first edge 1a, thereby clamping the sheet-like cleaning member from a lower position toward the first edge 1a, thereby ensuring that the sheet-like cleaning member can be clamped. In this case, an adapter M is required. The second end 4b of the first connecting rod 4 is rotatably connected to the adapter M. The clamping unit 2 is rotatably connected to the adapter M, so that the clamping unit 2 can rotate relative to the adapter M. In this way, the clamping unit 2 can move along the guide slope 131 when extending outward and retracting inward.

[0057] Furthermore, the lower surface of the cover 14 is provided with a limiting slope 141 for limiting the clamping unit 2. The limiting slope 141 is parallel to the guide slope 131. Thus, while the guide slope 131 guides the clamping unit 2, the limiting slope 141 can limit the clamping unit 2, thereby reducing the up and down shaking of the clamping unit 2, and making the clamping unit 2 move more smoothly.

[0058] For the convenience of users, refer to Figure 1 、 Figure 3 and Figure 4 The mopping device in this embodiment also includes a vertical rod 8, the bottom end of the vertical rod 8 is connected to a pressure plate 9, one end of the pressure plate 9 is hinged to the base plate 1, and a linkage 10 is provided below the pressure plate 9. The pressure plate 9 rotates in the direction close to the base plate 1 and can drive the driving unit 3 to move in the direction close to the second edge 1b through the linkage 10. In this way, force can be applied to the driving unit 3 through the vertical rod 8, thereby avoiding the user from bending over to apply force to the driving unit 3 on the base plate 1, thereby facilitating user use.

[0059] There are many implementation methods of the above-mentioned connecting member 10. For example, the connecting member 10 can be a protrusion, and the pressure plate 9 rotates in the direction close to the substrate 1 to squeeze the driving unit 3 through the protrusion, thereby causing the driving unit 3 to move in the direction close to the second edge 1b; the connecting member 10 can also be a connecting rod, one end of the connecting rod is hinged to the pressure plate 9, and the other end is hinged to the driving unit 3. The pressure plate 9 rotates in the direction close to the substrate 1 to push the driving unit 3 through the connecting rod, thereby causing the driving unit 3 to move in the direction close to the second edge 1b; compared with the protrusion, the connecting rod is connected to both the pressure plate 9 and the driving unit 3, so it can play a certain limiting role on the pressure plate 9 and the vertical rod 8, preventing the pressure plate 9 and the vertical rod 8 from rotating at will.
