[0048] The technical solutions provided by the embodiments of the present application are described below with reference to the drawings.

[0049] Reference Figures 1-10 To solve the technical problem, the present specification provides a cloth clamping flat mop, specifically comprising a mop rod 1, a mop head 2 and a driving mechanism, the bottom of the mop head 2 is a wiping surface 201 which directly contacts the wiping cloth; at least two side ends of the mop head 2 movably install a cloth clamping mechanism 4 which can expand or retract to clamp the wiping cloth, the cloth clamping mechanism 4 is slidingly installed on one side of the mop head 2 away from the wiping surface 201 or the middle of the mop head 2; the driving mechanism drives the cloth clamping mechanism 4 to expand and retract, so that the cloth clamping mechanism 4 can switch between the expanded state and the retracted cloth clamping state. The cloth clamping mechanism 4 is used to wait for clamping the wiping cloth when it is in the expanded state, and the cloth clamping mechanism 4 clamps and fixes the wiping cloth during the process of switching from the expanded state to the retracted cloth clamping state.

[0050] The cloth clamping mechanism 4 comprises a supporting arm 401 and a cloth clamping claw 402 connected with the supporting arm 401, the cloth clamping claw 402 can swing towards the side of the wiping surface 201 (the cloth clamping claw 402 swings towards the side of the wiping surface 201 to contact and grab the wiping cloth), and the cloth clamping claw 402 is configured to swing towards the side of the wiping surface 201 during the overall extension of the cloth clamping mechanism 4;

[0051] When the cloth clamping mechanism 4 is in the expanded state, the cloth clamping mechanism 4 extends outward, and the cloth clamping jaw 402 expands outward and downward at the same time, and at this time, the cloth clamping jaw 402 is lower than the wiping surface 201; when clamping the cloth, the mop head 2 is abutted on the wiping cloth, the driving mechanism controls the cloth clamping mechanism 4 to switch from the expanded state to the inwardly retracted cloth clamping state, and the cloth clamping jaw 402 drives the wiping cloth to retract inwardly and reset, and the inwardly retracted cloth clamping state is the state of normal cleaning of the cloth clamping flat mop, and the cloth clamping mechanism 4 is slidingly installed on one side of the mop head 2 away from the wiping surface 201 (the height of the bottom surface of the cloth clamping jaw 402 in the inwardly retracted cloth clamping state is higher than that in the expanded state, that is, better clamping effect can be ensured and bumping of the cloth clamping jaw can be avoided).

[0052] In some embodiments, as shown in Figures 2-4 The mop head 2 is provided with a cloth clamping accommodation groove 3, and the height of the cloth clamping accommodation groove 3 is higher than that of the wiping surface 201; the cloth clamping mechanism 4 is slidingly installed in the cloth clamping accommodation groove 3, and the cloth clamping mechanism 4 in the inwardly retracted cloth clamping state forms a clamping between the cloth clamping jaw 402 and the mop head.

[0053] The wiping cloth of the embodiment of the present application is a non-woven fabric, and the actual mopping effect of the practical product of the cloth clamping flat mop adopting the above principle is good, the cloth clamping is accurate and reliable, and the switching of the cloth clamping is convenient.

[0054] In an example, the cloth clamping jaw 402 of the embodiment of the present application is hingedly installed on one side of the supporting arm 401 through a hinged shaft and can rotate upward and downward, and the cloth clamping jaw 402 can be flipped toward the wiping cloth side; the cloth clamping jaw 402 in the expanded state contacts the wiping cloth, and when the expanded state is switched to the inwardly retracted cloth clamping state, the cloth clamping jaw 402 clamps the wiping cloth.

[0055] It should be noted that the cloth clamping jaw 402 of the embodiment of the present application is different from the prior art, which can be driven by the supporting arm 401 to make a telescopic movement in the cloth clamping accommodation groove 3, and can also be flipped and swung relative to the supporting arm 401 to the wiping surface 201 side, so that the cloth clamping jaw 402 can be abutted on the wiping cloth to realize the grabbing of the wiping cloth, and the wiping cloth is finally clamped in combination with the guide convex edge to form a cloth clamping path, which is simple in operation and can realize “one-key replacement of wiping cloth”, and the cloth clamping jaw 402 in the expanded state has a large expanded stroke, which is convenient for the grabbing of the wiping cloth.

[0056] When clamping the cloth, the wiping surface 201 of the mop head 2 is placed on a new wiping cloth, and the cloth clamping jaw 402 in the expanded state (waiting for clamping) is abutted on the wiping cloth; in the process of switching the cloth clamping mechanism 4 from the expanded state to the inwardly retracted cloth clamping state, the supporting arm 401 guides the cloth clamping jaw 402 to retract and reset, and the cloth clamping jaw 402 corresponds to the wiping cloth from the plane where the wiping surface 201 is located, and finally the cloth clamping jaw forms a clamping. At this time, the cloth clamping mechanism 4 is in the inwardly retracted cloth clamping state.

[0057] In some embodiments, the height of the cloth clamping jaw 402 is lower than the wiping surface 201 when the cloth clamping mechanism 4 is in the unfolded state, ensuring that the entire mop head 2 is placed on the wiping cloth, and the cloth clamping jaw 402 can contact and clamp the wiping cloth.

[0058] It should be noted that when the cloth clamping jaw 402 of the embodiment of the present application extends outward in the cloth clamping accommodation groove 3, it can simultaneously realize downward movement (specifically, the embodiment of the present application is hinged and swings), so that the cloth clamping jaw 402 can abut to the plane where the wiping surface 201 is located (when the wiping surface 201 is placed on the wiping cloth, the cloth clamping jaw 402 can move to abut to the wiping cloth).

[0059] In some embodiments, as shown in Figure 4 As shown in Figure 8 The mop head 2 is provided with a pressure applying structure; when the cloth clamping jaw 402 is unfolded, the pressure applying structure moves the cloth clamping jaw 402 towards the side of the wiping surface 201. In the present embodiment, the pressure applying structure is a guide protrusion 208 arranged on the inner wall of the upper side of the mop head 2. The guide protrusion 208 can be arranged in multiple and spaced in a straight line direction. The guide protrusion 208 is configured to ensure that the cloth clamping jaw 402 maintains the state of the cloth clamping jaw 402 swinging downward when the cloth clamping jaw 402 is unfolded. The cloth clamping jaw 402 is provided with an avoiding groove 4021, and when the cloth clamping jaw 402 is retracted, the guide protrusion 208 is placed in the avoiding groove 4021.

[0060] This structure ensures that when the cloth clamping jaw 402 is unfolded, the guide protrusion 208 will come out of the avoiding groove 4021, and at this time the guide protrusion 208 will make the cloth clamping jaw 402 maintain the state of swinging downward, so that the cloth clamping jaw 402 swings relative to the supporting arm 401. The guide protrusion 208 maintains the state of the cloth clamping jaw 402 swinging downward, which is simple in structure, reliable in driving, and the guide protrusion 208 can be an integral structure with the mop head 2. When the cloth clamping jaw 402 is retracted into the mop head 2, the guide protrusion 208 is placed in the avoiding groove 4021 again, thereby avoiding, which is a clever design.

[0061] In some embodiments, the pressure applying structure is an elastic member mounted on the cloth clamping jaw 402. The elastic member is configured to make the cloth clamping jaw 402 always have a tendency to swing towards the side of the wiping surface 201. When the supporting arm 401 of the cloth clamping mechanism 4 drives the cloth clamping jaw 402 to slide outward and unfold, the elastic member drives the bottom surface of the cloth clamping jaw 402 to be lower than the wiping surface 201 (the cloth clamping jaw 402 always has a tendency to move towards the side of the wiping surface 201, achieving the grasping of the wiping cloth).

[0062] In some embodiments, the clamping claw 402 includes equally spaced and staggered protruding teeth 403. The staggered protruding teeth 403 are configured to firmly grip the wiping cloth, effectively increasing the gripping area of ​​the wiping cloth. The overall dimensions of the wiping cloth are larger than the length and width of the mop head 2.

[0063] like Figure 10 As shown, in a preferred embodiment, the protruding teeth 403 are eccentrically conical, so that the protruding teeth 403 are staggered on the clamping claws 402. The protruding teeth 403 of the embodiment in this specification are different from the existing tooth structure that simply adopts a linear array layout. The eccentrically arranged protruding teeth 403 are staggered on the clamping claws 402, which helps the protruding teeth 403 to better clamp the wiping cloth and ensure that the cloth is clamped accurately and reliably each time the wiping cloth is replaced.

[0064] In some embodiments, such as Figure 9 and Figure 10 As shown, the drive mechanism includes a drive cam 9 rotatably mounted at the end of the mop handle 1 and a drive frame 406. The drive cam 9 is connected to the mop handle 1 via a connector 8. The drive frame 406 is slidably mounted inside the mop head 2. Multiple pairs of inclined guide grooves 4061 are spaced apart along the length of the drive frame 406. An inclined guide post 4011 that cooperates with the inclined guide grooves 4061 is provided on the support arm 401. The inclined guide post 4011 is placed in the corresponding inclined guide groove 4061. The multiple pairs of inclined guide grooves 4061 and inclined guide posts 4011 cooperate to drive the cloth clamping claw 402 to have multiple clamping points. When the length of the cloth clamping claw 402 is large, if it is driven from both ends (i.e., clamping points on both sides), the cloth clamping claw 402 is prone to deformation. This structure uses multiple clamping points to prevent the cloth clamping claw 402 from deforming, making the cloth clamping more reliable.

[0065] A drive cam 9 is rotatably mounted at the end of the mop handle 1. The mop handle 1 adopts a twisted rod structure, which drives the drive cam 9 to rotate. The twisted rod structure of the mop handle 1 is existing technology and will not be described in detail in this embodiment. An eccentric column 901 is provided on the drive cam 9, and a guide groove 4062 matching the eccentric column 901 is provided on the drive frame 406. The eccentric column 901 is placed in the guide groove 4062. During driving, the mop handle 1 drives the drive cam 9 to rotate. The drive cam 9 drives the drive frame 406 to slide via the eccentric column 901. The drive frame 406 drives the support arm 401 to slide, and then the support arm 401 drives the clamping claw 402 to extend and retract.

[0066] Specifically, the mop head 2 comprises an upper cover 205 and a lower cover 206 which are buckled to each other, the upper cover 205 and the lower cover 206 are spliced to form the cloth containing groove 3; the guide buckle 204 is arranged on the upper cover 205, and the wiping surface 201 is located at one side of the bottom end of the lower cover 206. The decorative bottom plate is installed at the bottom of the lower cover 206 for forming the wiping surface 201, and it should be noted that the wiping surface 201 of the present application has a flat structure, so that the structure of the whole mop head 2 is simple and beautiful.

[0067] In some embodiments, as shown in Figure 3 the mop head comprises a mop plate, a wiping surface installed at the lower end of the mop plate, and a foam layer padded between the wiping surface and the mop plate, and the wiping surface is flexible rubber and / or plastic.

[0068] The two ends of the wiping surface in the length direction are lower than the middle end, and the middle end is compressed when the wiping surface contacts the ground, so that the wiping surface has better contact with the ground.

[0069] In the specification, the same or similar parts among various embodiments can be referred to each other, and each embodiment focuses on the difference from other embodiments.

[0070] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
