It is also to be understood that any one or more of the teachings, genes, compositions, example, embodiments, examples, or examples described herein can be combined in any

[0109] It is also to be understood that the drawings provided herein are for illustrative purposes and that the actual implementation can vary in terms of shape, size, and arrangement of components, and that the layout of components can be more complex.

[0110] In addition, in the following description, specific details are provided to thoroughly understand examples. However, one of ordinary skill in the art will understand that the examples can be practiced without these specific details.

[0111] The technical solutions provided by the embodiments of the present application are described below with reference to the accompanying drawings.

[0112] Referring to FIGS. 1-49, the present application provides a rolling type clamping mechanism of a wiping cloth, which includes a wiping main body 1 for installing the wiping cloth and a holding part connected with the wiping main body 1. The wiping main body 1 includes a bottom plate 101 for contacting the wiping cloth. When cleaning, the holding part is held by hand, and the surface to be cleaned (such as the ground, glass, wall, table, etc.) is cleaned. At least two side ends of the wiping main body 1 are rotatably connected with a cloth taking roller 2. In the embodiment of the present application, the cloth taking roller 2 is rotatably installed in the installation cavity with an opening at the side end of the wiping main body 1. The cloth taking roller 2 grabs the wiping cloth through the opening. When clamping the cloth, the cloth taking roller 2 is at least partially exposed to the wiping main body 1. The cloth taking roller 2 is provided with a structure for increasing the friction to facilitate the rolling of the cloth taking roller 2 to grab the wiping cloth. When clamping the cloth, the wiping main body 1 is placed on the wiping cloth. By rotating the cloth taking roller 2 inward or outward, the cloth taking roller 2 contacts the wiping cloth and rolls the contacted wiping cloth to be positioned on the wiping main body 1. The wiping cloth covers the bottom plate 101.

[0113] It should be noted that the shape of the wiping body 1 is not further limited in the embodiments of the present application, which can be rectangular, triangular or other shapes; when the wiping body 1 is rectangular, the cloth taking roller 2 is arranged in the length or width direction of the wiping body 1, preferably in the length direction; when the wiping body 1 is triangular, the cloth taking roller 2 is arranged on the three side ends of the wiping body 1 (at this time, the cloth taking roller 2 preferably rotates outward). The wiping body 1 of the embodiments of the present application is only taken as an example of a rectangle.

[0114] The cloth taking roller 2 can rotate forward and reverse; the wiping cloth is rolled and positioned on the wiping body 1 by forward rotation of the cloth taking roller 2 when clamping the cloth; and the wiping cloth is released for replacement by reverse rotation of the cloth taking roller 2 when replacing the cloth. The wiping cloth is clamped by forward rotation of the cloth taking roller 2, and the clamping is released by reverse rotation, at which time the cloth can be removed by hand or foot operation to release the wiping cloth.

[0115] The clamping mechanism of the present application is to grasp the wiping cloth by forward or reverse rotation of the cloth taking roller 2. When the cloth needs to be clamped, the cloth taking roller 2 can contact the wiping cloth, and the wiping cloth is wound onto the wiping body 1 by rotation of the cloth taking roller 2. The wiping cloth can be disposable non-woven fabric, household paper towel, wet paper towel, etc. Of course, the wiping cloth can also be reusable, as long as it can be grasped by the cloth taking roller 2 and wound onto the wiping body 1 when rolling and clamping. The wiping cloth is preferably disposable non-woven fabric.

[0116] It should be noted that the embodiments of the present application grasp and position the wiping cloth by rolling the cloth taking roller 2, which is a novel and reliable grasping method. At the same time, the wiping cloth can be grasped as a single sheet when clamping by rolling and grasping the wiping cloth with the cloth taking roller 2. When the wiping cloth is stacked in the storage box, the wiping cloth can be grasped as a single sheet by rolling and grasping the wiping cloth, which is similar to the principle of the paper taking roller of a printer grasping a single sheet of paper for printing.

[0117] In some embodiments, the friction-increasing structure is directly arranged on the outer surface of the cloth taking roller 2, and the cloth taking roller 2 grasps the wiping cloth through the friction-increasing structure. The friction-increasing structure can be one or more of a rubber pad (such as silicone), a friction pattern (as shown in FIG. 37, the friction-increasing structure is a knurling structure arranged directly on the surface of the cloth taking roller 2), a magic tape, an adhesive, a coating (such as a frosted coating that can increase friction), and a hook claw. It should be noted that the friction-increasing structure can also be directly arranged on the wiping cloth, and the friction-increasing structure is preferably arranged on the cloth taking roller 2.

[0118] In the present solution, the structure of increasing friction ensures that the cloth taking roller 2 can grab the wiping cloth contacted to the wiping main body 1; the rubber pad can be a silica gel structure; the friction pattern can be knurling structure, and the adhesive can be reusable glue (which can be directly purchased and will not be described in the specification).

[0119] When the cloth is clamped, the cloth taking roller 2 can rotate the wiping cloth to abut against the wiping main body 1, or the wiping cloth can be directly hooked on the magic tape or adhesive or hook claw of the cloth taking roller 2 by the hook claw. The rotation directions of the cloth taking rollers 2 arranged at the side ends of the wiping main body 1 are opposite when clamping the cloth, and the cloth taking rollers 2 rotate synchronously inward or synchronously outward.

[0120] In some embodiments, as shown in FIGS. 3 and 4, taking the flat mop as an example, the cloth taking roller 2 has a cloth clamping gap between the bottom plate 101 and the cloth taking roller 2, the cloth taking roller 2 rolls the wiping cloth into the cloth clamping gap to position the wiping cloth to the bottom plate 101, and the cloth clamping gap can also function as a positioning and clamping function for the wiping cloth at this time. The cloth taking roller 2 rotates inward (as shown in FIG. 4, the forward direction at this time is the direction of rotating inward) to grab the wiping cloth; the state of clamping the cloth is that the outer end of the wiping cloth is rolled and “pushed” into the cloth clamping gap by the cloth taking roller 2 (the wiping cloth is folded into the cloth clamping gap, and it is difficult to pull out the wiping cloth from the cloth clamping gap at this time). When the wiping cloth is a common paper towel, it is especially suitable for the cloth clamping mode of the cloth taking roller 2 rotating inward. In addition, when the structure of increasing friction adopts silica gel, knurling, coating and the like, it is especially suitable for the situation of the cloth taking roller 2 rolling inward to clamp the cloth.

[0121] As shown in FIGS. 3 and 4, the side end of the wiping main body 1 is provided with a side edge 102 corresponding to the cloth taking roller 2, and the cloth taking roller 2 and the side edge 102 form a cloth clamping gap. In the present embodiment, the cloth taking roller 2 grabs and “pushes” the wiping cloth to the side edge 102. For example, through the structure of increasing friction such as the rubber pad or friction pattern on the cloth taking roller 2, the wiping cloth is sent into the cloth clamping gap when clamping the cloth, and through the reverse rotation of the cloth taking roller 2, the wiping cloth is sent out of the cloth clamping gap when unclamping the cloth.

[0122] As shown in FIGS. 3 and 4, the included angle between the side edge 102 and the bottom plate 101 thereof is an acute angle.

[0123] In an example, as shown in FIG. 11, the cloth taking roller 2 is provided with a cloth clamping jaw 202 (i.e. a kind of hook jaw); when waiting for clamping cloth, the cloth clamping jaw 202 is towards the wiping cloth side, at this time the lower edge of the cloth clamping jaw 202 can be lower than the lower edge of the side end of the bottom plate 101, preferably the lower edge of the cloth clamping jaw 202 is lower than the lower edge of the side end of the bottom plate 101 (to ensure that when the wiping main body 1 is placed on the wiping cloth, through the rotation of the cloth taking roller 2, the cloth clamping jaw 202 can contact the wiping cloth). Of course, it needs to be pointed out that when the lower edge of the cloth clamping jaw 202 is higher than the lower edge of the side end of the bottom plate 101, it is not impossible to clamp the cloth; for example, when the wiping cloth is a relatively thick non-woven fabric, when the bottom plate 101 of the wiping main body 1 is contacted and pressed down to the wiping cloth, the wiping cloth on the outside will be caught and positioned on the wiping main body 1 by the rolling cloth taking roller 2 due to the partial upwarping, and the rolling clamping function can still be realized; of course, in actual use, the use effect is best when the lower edge of the cloth clamping jaw 202 is still lower than the lower edge of the side end of the bottom plate 101.

[0124] As shown in FIG. 11, the cloth clamping jaw 202 is preferably eccentrically arranged in a conical shape.

[0125] In some preferred embodiments, as shown in FIG. 11, the cloth taking roller 2 is an eccentric roller.

[0126] In some embodiments, as shown in FIGS. 10 and 14, the wiping main body 1 is provided with a bottom end 103 extending on one side of the bottom plate 101, and the lower edge of the bottom end 103 is higher than or equal to the lower edge of the side end of the bottom plate 101; when clamping the cloth, the cloth taking roller 2 is synchronously rotated outward to catch the wiping cloth to the side of the lower edge of the bottom end 103. The wiping cloth can be directly positioned against the bottom end 103, or can be directly hooked on the cloth taking roller 2 by the cloth clamping jaw 202 or a magic tape structure on the cloth taking roller 2, so as to position the wiping cloth on the wiping main body 1 (i.e. at this time the wiping cloth can not contact the bottom end 103).

[0127] As shown in FIG. 14, the bottom end 103 is a narrow edge, and the height of the lower edge of the bottom end 103 is preferably higher than that of the bottom plate 101, so as not to be bumped to the bottom end 103 during mopping use; the wiping cloth is clamped to the bottom end 103 by the cloth clamping jaw 202. At this time, the forward direction is the outward rotating direction. When clamping the cloth, the cloth clamping jaw 202 is rotated outward to abut the wiping cloth to the bottom end 103; as shown in FIG. 14, FIG. 14 is a structure schematic view of the wiping cloth being caught to the bottom end 103 by the cloth taking roller 2, and the clamped wiping cloth wraps the bottom plate 101.

[0128] In an embodiment, when clamping the cloth, the cloth taking roller 2 clamps or hooks the wiping cloth to the side end of the wiping main body 1.

[0129] As shown in FIGS. 17-25, the side end face of the wiping body 1 is provided with a side abutting portion 104, the height of the side abutting portion 104 is higher than the bottom plate 101, and when clamping the cloth, the cloth taking roller 2 clamps and abuts the wiping cloth to the side abutting portion 104. In this embodiment, the cloth taking roller 2 is used to grab the wiping cloth through the cloth clamping jaw 202.

[0130] In a preferred embodiment, considering that the rolling stroke of the cloth taking roller 2 outwardly rolling to grab the wiping cloth can be large, as shown in FIGS. 22-24, the wiping body 1 is floatingly installed with a floating plate 3 for hinging the cloth taking roller 2 at the side end, the floating plate 3 is internally installed with a reset elastic member 4, and the floating plate 3 is configured to be outwardly extended open or inwardly reset relative to the wiping body 1; when switching to the cloth clamping state, the floating plate 3 drives the cloth taking roller 2 to be inwardly reset, and the cloth taking roller 2 is synchronously rotated outwardly to clamp and abut the wiping cloth to the side abutting portion 104. At this time, the forward direction is the direction of outward rotation.

[0131] The side abutting portion 104 is arranged at the side end position of the wiping body 1, so part of the side end of the wiping body 1 is also wrapped by the wiping cloth, and when the wiping body 1 is placed on the ground, it can ensure that the wiping cloth first contacts the ground and does not bump and wear the wiping body 1.

[0132] It should be noted that in this embodiment, the cloth taking roller 2 is rolling clamped by the retracting movement of the floating plate 3 during the cloth clamping process, which avoids tearing the wiping cloth (such as ordinary paper towel) when grabbing the wiping cloth, so that the cloth clamping fails. As shown in FIGS. 23 and 24, the rolling stroke of the cloth taking roller 2 can be large, and if the wiping cloth is directly grabbed by the cloth clamping jaw 202 or other structures that increase friction, the rolling stroke is greater than the deformable amount of the wiping cloth, which causes the wiping cloth to be torn or separated from the cloth taking roller 2. Therefore, the floating plate 3 can be preferably used to cooperate with the cloth taking roller 2 to roll clamp. It should be noted that not all cloth taking rollers 2 that rotate outwardly need to be provided with a movable floating plate 3, and the floating plate 3 is a preferred arrangement.

[0133] In another embodiment, as shown in FIGS. 25 and 36, the side end of the wiping body 1 is provided with a hollow cavity 105, and the cloth clamping jaw 202 directly hooks the wiping cloth into the hollow cavity 105; as shown in FIG. 27, the included angle between the cloth clamping jaw 202 and the bottom plate 101 after the cloth clamping is completed is less than or equal to 90 degrees. At this time, the wiping cloth is hooked by the cloth clamping jaw 202 in the hollow cavity 105. It should be noted that the cloth clamping jaw 202 of the cloth taking roller 2 can also be realized by a magic tape or other structures that increase friction.

[0134] In some embodiments, the bottom plate 101 is mounted on the wiping body 1, and the wiping body 1 is convex in the middle to form a hump, which is configured to deform when the bottom plate 101 contacts the ground, so that the wiping cloth is better attached to the surface to be cleaned. The bottom plate 101 is preferably fastened to the wiping body 1.

[0135] In some embodiments, the wiping body 1 is provided with a driving part for driving the cloth taking roller 2 to rotate.

[0136] Specifically, as shown in FIGS. 7, 13, 21, 26, 28, 32, 37, and 41, the driving part can be a moving plate 5 that can move outward or inward, and the moving plate 5 drives the cloth taking roller 2 to rotate through the extension and retraction movement. In some embodiments, as shown in FIGS. 7, 13, 21, and 26, the moving plate 5 is driven by a gear and rack structure, and the cloth taking roller 2 is provided with a cloth taking gear 201, and the moving plate 5 is provided with a first rack part 501 corresponding to the cloth taking gear 201.

[0137] In some embodiments, as shown in FIGS. 28, 30, 32, and 34, the moving plate 5 is connected to the cloth taking roller 2 by a connecting rod 503, and the connecting rod 503 drives or pulls the cloth taking roller 2 to rotate, and the connecting rod 503 is eccentrically arranged with the hinge point of the cloth taking roller 2.

[0138] In addition, the cloth taking roller 2 can also be driven by a friction wheel structure and the moving plate 5, and the cloth taking roller 2 is provided with a cloth taking friction wheel, and the moving plate 5 is provided with a friction strip corresponding to the cloth taking friction wheel, and the cloth taking friction wheel is driven to roll by the friction strip.

[0139] It should be noted that the driving part can also drive the cloth taking roller 2 to rotate by other means such as a belt wheel.

[0140] In other embodiments, the wiping body 1 is provided with a driving part for driving the cloth taking roller 2 to rotate, and the cloth taking roller 2 is provided with a cloth taking gear 201, and the driving part is a multi-stage gear set that meshes with the cloth taking gear 201, that is, the driving part directly transmits power to the cloth taking roller 2 by the meshing mode of the multi-stage gear set.

[0141] In some embodiments, the wiping body 1 is also provided with a linkage 7 for controlling the movement of the driving part, and the movement (which can be movement or rotation) of the linkage 7 drives the driving part to rotate the cloth taking roller 2.

[0142] In one embodiment, the linkage 7 is rotatable, as shown in FIGS. 7, 13, 21, and 26, the linkage 7 is a transmission gear meshing with the gear of the moving plate 5. The extension and retraction movement of the moving plate 5 is achieved by the meshing transmission of the gear and the rack; as shown in FIGS. 6 and 12, the moving plate 5 is provided with a second rack portion 502 meshing with the moving plate 5.

[0143] In another embodiment, as shown in FIGS. 28, 30, 31, 39, and 40, the linkage 7 is a rotatable eccentric cam, the moving plate 5 is provided with a cam shaft 504, and the eccentric cam is provided with a cam groove 701 cooperating with the cam shaft 504. It should be noted that the cam shaft 504 can also be provided on the eccentric cam, and the cam groove 701 is provided on the moving plate 5.

[0144] In another embodiment, as shown in FIGS. 34 and 43, the linkage 7 is an eccentric crank shaft 702, which pushes the moving plate 5 to move through the swing of the eccentric crank shaft 702.

[0145] In one example, the moving plate 5 is directly provided with a waist-shaped groove cooperating with the eccentric crank shaft 702, the waist-shaped groove is arranged along the length direction of the wiping body 1, so that the eccentric crank shaft 702 and the moving plate 5 directly form a crank slider mechanism (not shown in the drawings of the present specification), and the extension and retraction movement of the two moving plates 5 is achieved by the rotation of the linkage 7.

[0146] In another example, as shown in FIGS. 34, 35, 41, and 43, the moving plate 5 is connected to the eccentric crank shaft 702 through a slidable sliding plate 11, the sliding plate 11 reciprocates along the length direction of the wiping body 1; the sliding plate 11 is provided with a swing groove 1101 cooperating with the eccentric crank shaft 702, the moving plate 5 is provided with a cooperating shaft 505, and the sliding plate 11 is provided with an oblique groove 1102 slidingly cooperating with the cooperating shaft 505. The sliding direction of the sliding plate 11 is parallel to the length direction of the wiping body 1, and the extension and retraction movement direction of the moving plate 5 is parallel to the width direction of the wiping body 1, so the sliding direction of the sliding plate 11 is perpendicular to the moving direction of the moving plate.

[0147] It should be noted that the driving part of the clamping mechanism of the present specification can drive the cloth taking roller 2 in multiple ways, and the linkage 7 can also achieve the extension and retraction movement of the moving plate 5 in multiple ways, so as to rotate the cloth taking roller 2.

[0148] In some embodiments, as shown in FIG. 1, the gripping part is an operating rod 6; the operating rod 6 is in transmission connection with the linkage 7, and the rotation of the linkage 7 is achieved by the up and down movement of the operating rod 6 along the axial direction; the present embodiment is mainly suitable for flat mop, and can also be applied to window cleaner, desktop wipe, and the like.

[0149] In some embodiments, referring to FIGS. 1-4, the operating rod 6 comprises an inner rod 601 and an outer rod 10 which can be sleeved with each other, and the outer rod 10 is hinged to the wiping body 1 through the universal joint 12 (also known as outer cross hinge shaft), and the inner rod 601 is in transmission connection with the linkage 7.

[0150] Referring to FIGS. 3 and 4, the inner rod 601 is connected with the twist rod 8 which is hinged to the linkage 7 through the inner cross hinge shaft 9; through the up and down movement of the inner rod 601 along the axial direction, the twist rod 8 is driven to rotate and drive the linkage 7 to move relative to the inner cross hinge shaft 9.

[0151] In some embodiments, as shown in FIGS. 1 and 8, the universal joint 12 is provided with a positioning pin 1201 which is configured to keep the operating rod 6 and the wiping body 1 in a vertical state (this state can be used for cloth changing operation, and is suitable for the structure driven by the twist rod and the like); as shown in FIG. 8, the wiping body 1 is provided with a positioning pin groove 106 corresponding to the positioning pin 1201. Similarly, as shown in FIG. 1, the outer rod 10 is also provided with a positioning pin structure which is the same as the positioning pin 1201 in principle.

[0154] Specifically, as shown in FIGS. 2, 3, 4 and 8, in an example, the catch tooth 602 of the lock catch is arranged at the lower end of the inner rod 601, and the catch table 801 is arranged on the twist rod 8; when the cloth clamping or wiping is completed, the catch tooth 602 is engaged on the catch table 801 to form a certain self-locking (as shown in FIGS. 2 and 4). At this time, the inner rod 601 cannot be pulled upward at will, and only when the engagement force of the catch tooth 602 and the catch table 801 is overcome, the inner rod 601 can continue to move upward for operation (for example, the hands hold the inner rod 601 and the outer rod 10 respectively, and only when the self-locking engagement force of the lock catch is overcome, the inner rod 601 can move upward relative to the outer rod 10). Therefore, the lock catch realizes self-locking through the structure that the catch tooth 602 cooperates with the catch table 801 of the twist rod 8, so that the cloth taking roller is kept in the state of clamping cloth, so that the wiping cloth does not fall off and the like when the wiping cloth is wiped and cleaned.

[0155] In some embodiments, as shown in FIGS. 44 and 47, the linkage 7 is directly exposed on the wiping body 1, and the driving part and the cloth taking roller 2 are driven to move by directly triggering the linkage 7.
