Description

[Technical Field]

[0001] The present invention relates to the technical field of household flat mops, and more particularly to flat mops that hold cloths. [Background technology]

[0002] A flat mop is a cleaning tool commonly used at home, and mainly includes a handle and a mop head used for mopping floors. A wiper cloth is attached to the bottom of the mop head, and the wiper cloth is usually flat. A cloth clamping mop is a type of flat mop. In cloth clamping mops currently on the market, the clamping claws and the wiping surface at the bottom of the mop head are on the same plane. In actual use, when mopping a floor, the clamping claws that clamp the wiper cloth come into direct contact with the floor, causing wear and affecting the aesthetics of the floor. The applicant cites a Chinese utility model with publication number "CN219846427U" as an example, which discloses a mop with a clamping cloth that allows for easy replacement of the mop cloth. The mop with a clamping cloth includes a handle and a mop base. The mop base is provided with a clamping assembly for clamping the mop cloth. The clamping assembly includes a first clamping member fixed to one end of the mop base remote from the handle, and a second clamping member movably connected to the mop base and movable toward and away from the first clamping member. In accordance with the present specification and drawings, the bottoms of the second clamping members on both sides are designed to be flush with the bottoms of the first clamping members. However, after the second clamping member clamps the mop cloth, the bottom of the second clamping member is exposed to the floor and comes into direct contact with the floor, which causes wear when mopping the floor and has certain limitations in use.

[0003] In the prior art, for example, a Chinese invention with application number "201310227871.2" discloses a dust mop, including a handle and a mop pallet connected to the handle, with one side of the mop pallet provided with a mounting mechanism for mounting a dust cloth or dust paper towel, the mounting mechanism including a mounting groove and a clamping device connected to the mounting groove, the clamping device having a hollow structure and several clamping grooves on its surface, the clamping device is installed on the upper end surface of the mop pallet, and the dust cloth needs to be manually removed and installed, i.e., the used dust cloth needs to be manually removed from the clamping groove and a new dust cloth needs to be partially inserted into the clamping groove, making it difficult to replace the dust cloth. For example, in a Chinese utility model with application number "200420082055.3", the disclosed mop cloth clamping structure includes a panel connected to the mop cloth, to which a clamping claw with teeth on its outer edge is hingedly connected, and the hinged clamping claw requires the clamping claw to be manually opened in order to replace the mop cloth. Summary of the Invention [Problem to be solved by the invention]

[0004] The problem that the present invention aims to solve is to provide a flat mop that clamps the wiper cloth, and by using the guide plate and the clamping claws of the clamping mechanism, it is possible to automatically clamp the wiper cloth with one click. The operation is simple, there is no need to touch the wiper cloth, and the clamping claws will not be damaged when mopping the floor, thereby solving the defects in the prior art.

[0010] In some embodiments, a pressure structure is disposed within the mop head such that when the clamping claws are deployed, the pressure structure moves the clamping claws closer to the wiping surface.

[0011] In some embodiments, the pressure structure is a guide flange mounted on an upper inner wall of the mop head, the guide flange configured to provide a motive force that moves the clamping claws toward the wiping surface whenever the clamping claws are deployed.

[0012] In some embodiments, the clamping jaws are provided with undercuts, and the guide flanges are placed within the undercuts after the clamping jaws are retracted inward.

[0013] In some embodiments, the pressure structure is an elastic member attached to the clamping claw, the elastic member configured to cause the clamping claw to always swing toward the wiping surface, and when the support arm of the clamping mechanism drives the clamping claw to slide outward and deploy, the elastic member drives the clamping claw to a position lower than the wiping surface.

[0014] In some embodiments, the resilient member comprises a torsion spring attached to a hinged connection of the clamping jaw, one end of the torsion spring being attached to the support arm and the other end being located in the clamping jaw.

[0015] In some embodiments, the clamping claw includes equally spaced teeth that are staggered and configured to securely clamp the wiper cloth.

[0016] In some embodiments, the guide plate has a groove corresponding to the convex tooth portion, so that the wiper cloth is engaged in the groove, and a concave-convex clamping method is used to increase the friction and clamping force for clamping the wiper cloth.

[0017] In some embodiments, the convex toothed portion has an eccentric cone shape, and the guide plate has an engaging tooth disposed between two adjacent convex toothed portions, the engaging tooth facing the cloth receiving chamber.

[0018] In some embodiments, a drive stand is slidably mounted within the mop head, and a plurality of inclined guide grooves are spaced apart along the length of the drive stand. The support arm is provided with an inclined guide column that fits into the inclined guide grooves, and is driven by the inclined guide grooves, so that the clamping claws have a plurality of clamping points.

[0019] In some embodiments, a drive cam is rotatably mounted on the end of the handle, an eccentric column is mounted on the drive cam, and a guide groove is mounted on the drive stand to fit the eccentric column.

[0025] The clamping mechanism of the present invention allows both sides of the mop head to extend outward or retract inward, and its clamping claws can move toward the wiping surface. After the wiping surface of the mop head is placed on the external wiper cloth, the clamping claws can come into contact with the wiper cloth. When the clamping claws of the clamping mechanism retract inward to clamp the cloth, the wiper cloth is guided by the guide plate and finally clamped into the cloth storage tub. The cloth storage tub is higher than the wiping surface, so there is no need to worry about hitting the clamping claws when mopping the floor every day.

[0026] The clamping claw of the present invention is hingedly attached to the support arm of the clamping mechanism so that the clamping claw can flip downward to "clamp" the wiper cloth, and a resilient torsion spring installed at the hinge connection allows the clamping claw to securely clamp the wiper cloth.

[0027] The clamping claw according to the present invention includes convex tooth portions arranged in a staggered pattern at equal intervals, and the convex tooth portions are arranged eccentrically, so that the wiper cloth can be clamped effectively.

[0028] The clamping mechanism of the present invention rotates the drive gear shaft via a handle, allowing the support arm to contract inward or extend outward. When extended outward, the clamping claw is driven downward via a torsion spring to clamp the wiper cloth. When contracted inward, the wiper cloth is clamped in the cloth storage tank. The overall operation is convenient and reliable, and replacing the wiper cloth is simple; there is no need to touch the wiper cloth, making operation easy, and it can be achieved by "replacing the wiper cloth with one click."

[0032] The present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0035] It should be further explained that the drawings provided in the following examples are for roughly explaining the basic concept of the present application, and only assemblies related to the present application are shown in the drawings, and are not drawn according to the number, shape and dimensions of the assemblies when actually implemented; the form, number and ratio of each assembly when actually implemented can be freely changed, and the layout form of the assembly can also be more complex.

[0036] Also, in the following description, certain details are provided to provide a thorough understanding of the embodiments, but it should be understood by those skilled in the art that the embodiments may be practiced without these specific details.

[0037] The technical solutions provided by the embodiments of the present application will be described below in conjunction with the drawings.

[0038] As shown in Figures 1 and 4, in order to solve the technical problems, this specification provides a cloth clamping flat mop, specifically including a handle 1, a mop head 2, and a drive mechanism. The bottom of the mop head 2 is a wiping surface 201, to which a wiper cloth 5 is attached so as to be in direct contact. Clamping mechanisms 4 that can be unfolded or retracted inward to clamp the cloth are movably attached to both the front and rear ends of the mop head 2. The clamping mechanisms 4 are used to clamp the wiper cloth 5. The drive mechanism drives the clamping mechanisms 4 to extend and retract, so that the clamping mechanisms 4 can be switched between an unfolded state and a state in which they retract inward to clamp the cloth. When the clamping mechanism 4 is in the unfolded state, it waits to clamp the wiper cloth 5, but when it switches from the unfolded state to the state in which it retracts inward to clamp the cloth, it clamps and secures the wiper cloth 5.

[0039] The clamping mechanism 4 includes a support arm 401 and a clamping claw 402 connected to the support arm 401, and the clamping claw 402 is movable toward the wiping surface 201 (the clamping claw 402 moves toward the wiping surface 201 to contact and clamp the wiper cloth 5), and the clamping claw 402 is configured to move toward the wiping surface 201 in synchronization when the entire clamping mechanism 4 extends outward.

[0040] Here, guide plates 202 are provided on the back surfaces of both sides of the wiping surface 201, and when the clamping mechanism 4 is in the unfolded state, it protrudes outward, and the clamping claws 402 are unfolded outward and downward along the guide plates 202. At this time, the clamping claws 402 are lower than the wiping surface 201. When clamping the cloth, the mop head 2 abuts against the wiper cloth 5, and the drive mechanism controls the clamping mechanism 4 to switch from the unfolded state to a state in which it contracts inward to clamp the cloth, and the clamping claws 402, together with the wiper cloth 5, contract inward along the guide plates 202 and return. The guide plates 202 are used to guide the wiper cloth 5 to a state in which it contracts inward to clamp the cloth, and the state in which it contracts inward to clamp the cloth is the state in which the flat mop with the cloth clamped is used for mopping or cleaning.

[0041] In some preferred embodiments, as shown in FIGS. 5 and 6, the guide plate 202 is an inclined guide plate, and is used together with the clamping claw 402 to guide the wiper cloth 5 .

[0042] In another embodiment, as shown in FIG. 17, the guide plate 202 may be a tapered guide plate, and the thickness of the tapered guide plate is preferably such that it does not interfere with the clamp claws 402, and is generally a thin plate structure of 1 to 3 mm, and the tapered guide plate extends outward from the outer end of the clamp claws 402 (as shown in FIG. 17, the tapered guide plate extends outward from the clamp claws 402 which are contracted inward to clamp the cloth).

[0043] As shown in FIG. 4, the angle between the guide plate 202, which is obliquely installed, and the wiping surface 201 is an acute angle.

[0044] It should be noted that the clamping mechanism 4 is slidably mounted on the side of the mop head 2 away from the wiping surface 201 (the clamping claws 402, when contracted inward to clamp the cloth, are higher than the wiping surface 201). In some embodiments, as shown in Figures 4 and 5, the mop head 2 is provided with a cloth storage tub 3, the height of the cloth storage tub 3 is higher than the wiping surface 201, the guide plate 202 extends into the cloth storage tub 3, the clamping mechanism 4 is slidably mounted within the cloth storage tub 3, and the clamping claws 402 of the clamping mechanism 4, when contracted inward to clamp the cloth, are contracted inside the cloth storage tub 3. Figure 16 is an actual diagram of the clamp mechanism 4 clamping the wiper cloth 5 to the cloth storage tub 3 while contracting inward to hold the cloth. At this time, the clamp mechanism 4 contracts inside the cloth storage tub 3, and the clamp claws 402 that clamp the wiper cloth 5 are also installed inside the cloth storage tub 3. The clamp mechanism 4 allows the wiper cloth 5 to completely cover the wiping surface 201 in both the front and back directions, which is effective for mopping floors. This avoids the problem of the clamp claws being flush with the wiping surface and becoming exposed and worn when mopping a floor, as in the prior art.

[0045] The guide plate 202 forms a clamping path when clamping the wiper cloth 5, and guides the clamping claws 402 to clamp the wiper cloth 5 into the cloth storage tub 3 (the outer part of the wiper cloth 5 is folded back into the cloth storage tub 3). As shown in Figure 15, the clamping mechanism 4 on the mop head 2 is shown clamping the wiper cloth 5 into the cloth storage tub 3 in an actual view. The clamping mechanism 4 automatically "pushes" the wiper cloths 5 on both the front and rear sides into the cloth storage tub 3, achieving the purpose of automatically clamping the wiper cloths 5. The wiper cloths can be easily replaced, and there is no need to manually attach the wiper cloth 5 to the mop head 2, avoiding the need to touch the wiper cloth 5.

[0046] The wiper cloth 5 according to the embodiment of this specification is made of nonwoven fabric, which is an actual product of a flat mop that clamps the cloth using the above principle, and is effective for actually mopping floors, with accurate and reliable cloth clamping and convenient cloth replacement.

[0047] In one example, the clamp claw 402 according to the embodiment of the present specification is hinged and can rotate up and down on one side of the support arm 401 via a hinge axis, and the clamp claw 402 can be reversed in the direction of the wiper cloth 5 and approach it, and when the clamp claw 402 is in an expanded state, it comes into contact with the wiper cloth 5, and when it switches from the expanded state to a state in which it contracts inward to clamp the cloth, the clamp claw 402 clamps the wiper cloth 5 in the cloth storage tank 3.

[0048] It should be noted that, unlike the prior art, the clamping claws 402 according to the embodiments of the present specification are not only driven by the support arm 401 to extend and retract within the cloth storage bin 3, but can also pivot in a reverse direction relative to the support arm 401 toward the wiping surface 201. The clamping claws 402 can contact the wiper cloth 5 to clamp it. Furthermore, the guide plates 202 on both sides form a clamping path, ultimately clamping and positioning the wiper cloth 5 within the cloth storage bin 3 for easy operation and enabling "one-click wiper cloth replacement." The inclined guide plates 202 also contribute to stable cloth clamping. The extended stroke of the clamping claws 402 in the extended state allows for easy clamping of the wiper cloth 5.

[0049] When the clamping mechanism 4 clamps the cloth, as shown in Figure 14, the wiping surface 201 of the mop head 2 is placed on a new wiper cloth 5, and the clamping claws 402, which are in an expanded state (waiting to clamp the cloth), come into contact with the wiper cloth 5, and the clamping mechanism 4 switches from the expanded state to a state in which it contracts inward to clamp the cloth, and the support arm 401 guides the clamping claws 402 to contract inward and return, and the clamping claws 402 are guided by the guide plate 202 to finally clamp the wiper cloth 5 from the plane where the wiping surface 201 is located into the cloth storage tub 3. As shown in Figure 14, at this time the clamping mechanism 4 is contracted inward to clamp the cloth, and the clamping claws 402 contract into the cloth storage tub 3.

[0050] In some embodiments, when the clamping mechanism 4 is in the deployed state, the height of the clamping claws 402 is lower than the wiping surface 201, and the clamping claws 402 can contact and clamp the wiper cloth 5 after confirming that the entire mop head 2 is placed on the wiper cloth 5, as shown in FIG. 14.

[0051] It should be noted that when the clamp claws 402 in the embodiments of this specification extend outward from within the cloth storage tank 3, they can synchronously move downward (specifically, in the embodiments of this specification, this is a swinging movement due to a hinge connection), and therefore the clamp claws 402 can abut against the plane on which the wiping surface 201 exists (the wiping surface 201 can be placed on the wiper cloth 5, and the clamp claws 402 can move and abut against the wiper cloth 5).

[0052] 18 and 19, a pressure structure is provided within the mop head 2, and when the clamp claws 402 are deployed, the pressure structure moves the clamp claws 402 closer to the wiping surface 201. In this embodiment, the pressure structure is a guide flange 208 provided on the upper inner wall of the mop head 2. The guide flanges 208 may be provided in multiple locations spaced apart along a straight line, and are configured to provide a driving force that always moves the clamp claws 402 toward the wiping surface 201 when the clamp claws 402 are deployed. A recess 4021 is provided in the clamp claws 402, and the guide flange 208 is located within the recess 4021 after the clamp claws 402 are retracted inward.

[0053] In this structure, when the clamp claw 402 is deployed, the guide flange 208 comes out of the relief groove 4021. At this time, the guide flange 208 presses the clamp claw 402, causing the clamp claw 402 to swing relative to the support arm 401, and the clamp claw 402 is driven to swing through the guide flange 208. The structure is simple and the drive is reliable. The guide flange 208 and the mop head 2 may be an integrated structure. When the clamp claw 402 retracts inside the mop head 2, the guide flange 208 is again placed in the relief groove 4021 to retreat. This design is ingenious.

[0054] In some embodiments, the pressure structure is an elastic member attached to the clamping claw 402, and the elastic member is configured so that the clamping claw 402 always tends to swing toward the wiping surface 201, and when the support arm 401 of the clamping mechanism 4 drives the clamping claw 402 to slide outward and deploy, the elastic member drives the clamping claw 402 to a position lower than the wiping surface 201 (the clamping claw 402 always tends to move toward the wiping surface 201, thereby achieving clamping of the wiper cloth 5).

[0055] In one example, as shown in FIG. 8, the elastic member includes a torsion spring 6 attached to the hinge connection of the clamping jaw 402, with one end of the torsion spring 6 attached to the support arm 401 and the other end mounted to the clamping jaw 402.

[0056] In some embodiments, as shown in FIGS. 1 and 10 , the clamping claws 402 include convex teeth 403 arranged in a staggered pattern at equal intervals, and the staggered convex teeth 403 are configured to firmly clamp the wiper cloth 5, effectively increasing the clamping area for clamping the wiper cloth 5.

[0057] In some preferred embodiments, as shown in FIG. 5, the guide plate 202 is provided with a groove 207 corresponding to the convex tooth portion 403, so that the wiper cloth 5 is engaged in the groove 207, and the friction and clamping force for clamping the wiper cloth 5 are increased by using a concave-convex clamping method.

[0058] 13 and 14 show the clamping mechanism 4 of the mop head 2 in the deployed state.

[0059] As shown in FIG. 15, the wiper cloth 5 is larger than the length and width of the mop head 2 as a whole (in the figure, the wiper cloth 5 is for reference only, and its length and width dimensions can be separately designed and optimized).

[0060] As shown in FIG. 10, in one preferred embodiment, the convex tooth portion 403 is eccentrically conical, and the convex tooth portion 403 is arranged in a staggered pattern on the clamping claw 402. The convex tooth portion 403 in the embodiment of this specification is different from the conventional tooth structure that simply adopts a linear array arrangement. The eccentrically installed convex tooth portion 403 is arranged in a staggered pattern on the clamping claw 402, which helps to better clamp the wiper cloth 5 and ensures that the cloth is clamped accurately and reliably when replacing the wiper cloth 5.

[0061] In some preferred embodiments, as shown in FIG. 5, the guide plate 202 has an engagement tooth 203 between two adjacent convex tooth portions 403, facing the cloth storage tank 3, and the engagement tooth 203 is higher than the guide plate 202, and the engagement tooth 203 serves to assist in clamping the wiper cloth 5.

[0062] As shown in FIG. 5, in one example, the engagement teeth 203 are saw-tooth portions.

[0063] In some embodiments, as shown in Figures 20 and 21, a drive stand 406 is slidably mounted within the mop head 2, and a plurality of inclined guide grooves 4061 are spaced apart along the length of the drive stand 406. The support arm 401 is provided with inclined guide columns 4011 that fit into the inclined guide grooves 4061. The inclined guide columns 4011 are installed within the corresponding inclined guide grooves 4061, and are driven by the plurality of inclined guide grooves 4061 and the inclined guide columns 4011, so that the clamping claws 402 have multiple clamping points. When the length of the clamping claws 402 is increased, if the clamps are driven by both ends (i.e., both sides have clamping points), the clamping claws 402 are prone to deformation. However, with this structure, multiple clamping points are used, which can prevent the clamping claws 402 from deforming and more reliably clamp the cloth.

[0064] A driving cam 9 is rotatably mounted on the end of the handle 1, and the handle 1 employs a twist rod structure, allowing the driving cam 9 to be rotated via the handle 1. The handle 1 having a twist rod structure is a conventional technology, and a detailed description thereof will be omitted in this embodiment. An eccentric column 901 is mounted on the driving cam 9, and a guide groove 4062 that fits the eccentric column 901 is mounted on the driving stand 406, and the eccentric column 901 is mounted in the guide groove 4062. When operating, the driving cam 9 can be rotated via the handle 1, and the driving cam 9 slides the driving stand 406 via the eccentric column 901, which slides the support arm 401, which in turn drives the clamp claw 402 to extend and retract.

[0065] In some embodiments, as shown in Figures 4 and 13, the drive mechanism includes a drive gear shaft 7 rotatably attached to the mop head 2. Specifically, the drive gear shaft 7 according to the embodiments of the present specification is rotatably engaged with the mop head 2, and as shown in Figure 9, a meshing rack 404 meshing with the drive gear shaft 7 is correspondingly installed on the support arm 401, and the handle 1 is transmission-connected to the drive gear shaft 7, and the drive gear shaft 7 is rotated and driven through the handle 1 to switch the clamping mechanism 4 between the deployed state and the inwardly retracted and restored state.

[0066] It should be noted that the embodiments herein do not limit the specific structure of how the handle 1 drives the rotation of the gear shaft 7. The state of the clamping mechanism 4 can be switched by rotating the handle 1 in a circumferential direction (clockwise or counterclockwise) to control the rotation of the drive gear shaft 7. The state of the clamping mechanism 4 can also be switched by pressing the handle 1 axially (using a twist rod mechanism to convert vertical movement into rotational movement of the drive gear shaft 7). In one example, as shown in FIG. 4 , a twist rod transmission connection is used to transmit power, and a detailed description of this is omitted in the embodiments herein. When replacing the dirty wiper cloth 5, the handle 1 rotates the drive gear shaft 7 to switch the clamping mechanism 4 to the deployed state, allowing the dirty wiper cloth 5 to be removed (the dirty wiper cloth 5 can be stepped on with a foot until it is completely detached from the mop head 2).

[0067] In some embodiments, as shown in FIG. 12 , a guide buckle 204 is provided on the mop head 2, and a guide buckle groove 405 that slides with the guide buckle 204 is provided on the support arm 401, and the support arm 401 is slidably positioned within the cloth storage tub 3 of the mop head 2 by the sliding fit between the guide buckle 204 and the guide buckle groove 405.

[0068] Specifically, as shown in Figures 1, 5, 6 and 7, the mop head 2 includes an upper cover 205 and a lower cover 206 that are interlocked with each other, and the upper cover 205 and the lower cover 206 are joined together to form a cloth receiving basin 3. The guide buckle 204 is installed on the upper cover 205, the guide plate 202 is installed on the lower cover 206, and the wiping surface 201 is located at the lower end of the lower cover 206. A decorative substrate is attached to the bottom of the lower cover 206 to form the wiping surface 201.

[0069] It should be noted that the wiping surface 201 of the present invention has a flat structure, and the overall structure of the mop head 2 is simple and aesthetically pleasing.

[0070] As shown in FIGS. 4 and 6, the cross section of the lower cover 206 is an isosceles trapezoid as a whole (the hypotenuse of which is the structure of the guide plate 202).

[0071] In some embodiments, as shown in Figures 1 and 4, a guide sleeve 8 is fitted on the outside of the handle 1, and the guide sleeve 8 is hingedly attached to the mop head 2 via a universal joint 801, so that the handle 1 can rotate forward, backward, left and right, and the detailed description will be omitted in the embodiments of this specification.

[0072] In this specification, identical and similar parts among the embodiments can be mutually referenced, and each embodiment will be described focusing on the differences from other embodiments.

[0073] The above content is merely an embodiment of the present application, and the scope of the claims of the present application is not limited thereto, and any changes or modifications that can be easily made by a person skilled in the art within the technical scope disclosed by the present application should be included in the scope of the claims of the present application, and therefore the scope of protection of the present application should be in accordance with the scope of the claims of the present application.
