[0002] The flat mop is favored by people for its simple structure and efficient and convenient cleaning process. It generally includes a mop rod and a mop head rotatably connected to the mop rod. A mop cloth is arranged on the mop head. The mop cloth is generally a towel cloth or flannel cloth. After a period of use, the mop cloth needs to be hand washed or replaced. Therefore, the mop cloth and the mop head adopt a detachable connection structure such as pasting, snap-on or sleeve connection to facilitate the replacement or cleaning of the mop cloth. However, when the mop cloth needs to be removed, it is often already in a dirty state. However, in the above-mentioned connection structure, it is still necessary to touch the dirty mop cloth by hand, which is not hygienic and convenient. The flat mop disclosed in patent announcement number CN210144607U directly pastes the mop cloth on the mop board, and then pushes downward to the side of the mop head through the middle rod arranged at the connection position of the mop rod and the mop board, so that the middle of the mop cloth is raised and the mop cloth is disassembled and separated. However, this design is often not disassembled thoroughly, and the Velcro on the mop cloth is difficult to be completely separated from the mop head. Patent announcement number CN219895640U discloses a quick-release structure of a flat mop, in which a movable plate is arranged between an upper shell and a lower shell, and the movable plate is connected to a toggle member arranged on the upper shell. The movable plate is extended by the movement of the toggle member to fix the mop on the mop board, or the movable plate is retracted into the accommodating cavity by the movement of the toggle member to separate the mop board from the mop. However, during use, it is found that when the mop is cleaned with a mop bucket or a roller, the movable plate is very easy to retract and cause the mop to fall off, affecting the cleaning and use of the flat mop.

[0031] A linear chute is provided on the movable plate. The chute is arranged along the length direction of the mop head. A guiding groove is provided on the cover plate. The chute is sleeved outside the guiding groove and slides along the guiding groove. The guiding groove and the chute limit the position between the movable plate and the cover plate, so that the movable plate can only slide along the length direction of the mop head to avoid misalignment. That is, the chute and the guiding groove jointly form the first positioning device of the movable plate. When pushing or rotating the cloth discharging assembly to discharge the cloth, the end of the chute close to the hanging teeth contacts the guiding groove, restricting the first movable plate and the second movable plate from approaching each other further, and avoiding the permanent deformation caused by the excessive compression of the return spring. When the return spring resumes deformation, the end of the chute far from the hanging teeth contacts the guiding groove, restricting the first movable plate and the second movable plate from moving away from each other further and disengaging from the mop head. Further, the bottom plate is fixedly connected to the cover plate by being snap-fitted into the card hole through the second tongue. A long strip-shaped sliding hole is provided at the bottom of the chute, and the card hole is arranged on the side wall of the guiding groove. In this way, the second tongue and the sliding hole jointly form the second positioning device of the movable plate. That is, when pushing or rotating the cloth discharging assembly to discharge the cloth, the end of the sliding hole close to the hanging teeth contacts the second tongue, restricting the first movable plate and the second movable 2 from approaching each other further, and avoiding the problem of permanent deformation caused by the excessive compression of the return spring. When the return spring resumes deformation, the end of the sliding hole far from the hanging teeth contacts the second tongue, restricting the first movable plate and the second movable plate from moving away from each other further and disengaging from the mop head, thereby restricting the moving direction of the movable plate and the positional relationship between the movable plate, the cover plate and the bottom plate. The overall structure is simple, convenient and practical. Description of the Drawings

Detailed implementation mode

[0045] The following further describes the present utility model with reference to the accompanying drawings:

[0046] As Figures 1 to 12As shown in the figure, a flat mop that is convenient for replacing the mop cloth includes a mop head 1. A mop rod 2 is rotatably connected to the mop head 1. The mop head 1 includes a bottom plate 4 and a cover plate 3. A first movable plate 51 and a second movable plate 52 that can move along the length direction of the mop head 1 are provided between the bottom plate 4 and the cover plate 3. The first movable plate 51 and the second movable plate 52 are longitudinally arranged along the length direction of the mop head 1. Hanging teeth 54 for connecting the mop cloth 12 are provided on the first movable plate 51 and the second movable plate 52. Hanging sleeves 13 that cooperate with the hanging teeth 54 are provided on the mop cloth 12. Inserting the hanging teeth 54 into the hanging sleeves 13 at both ends of the mop cloth 12 installs the mop cloth 12 on the mop head. The first movable plate 51 and the second movable plate 52 are also connected to a cloth unloading assembly. The cloth unloading assembly includes a gear 61. A first rack 511 that meshes with the gear 61 is provided on the first movable plate 51. A second rack 621 that meshes with the gear 61 is provided on the second movable plate 52. The driving part 6 drives the first movable plate 515 and the second movable plate 52 to approach each other through the cloth unloading assembly, shortening the distance between the hanging teeth 54, that is, the hanging teeth 54 are hidden in the bottom plate 4. In this way, the hanging teeth 54 are disengaged from the hanging sleeves 13, enabling the mop cloth 12 to be automatically separated from the mop head 1, and the mop cloth 12 can be quickly disassembled without the need to manually contact the dirty mop cloth. Further, the first rack 511 and the second rack 621 are oppositely arranged along the length direction of the mop head 1, and the gear 61 is arranged between the first rack 511 and the second rack 621.

[0047] A return spring 7 is provided between the first movable plate 51 and the second movable plate 52. When the driving part 6 drives the first movable plate 51 and the second movable plate 52 to approach each other relatively, the return spring 7 is compressed and deformed. After releasing the driving part 6, the return spring 7 restores its deformation and pushes the first movable plate 51 and the second movable plate 52 to move away from each other, causing the hanging teeth 54 to extend and exposing the hanging teeth 54 from the bottom plate 4 to maintain the connection state with the mop cloth 12. Then, the hanging sleeves 13 at both ends of the mop cloth 12 can be sleeved on the hanging teeth 54. Further, to ensure that there is still a repulsive force between the first movable plate 51 and the second movable plate 52 and they cannot approach each other, when the hanging teeth 54 are in the initial extended state, the return spring 7 is still in a slightly compressed state and always has a deformation force to squeeze the first movable plate 51 and the second movable plate 52 to move away from each other.

[0048] In a preferred case, the hanging teeth 54 are provided on one side of the first movable plate 51 close to the end of the mop head, and on one side of the second movable plate 52 close to the end of the mop head 1. There is a gap between the first movable plate 51 and the second movable plate 52. Rotating or pushing the driving part 6 causes the first movable plate 51 and the second movable plate 52 to move towards each other along the length direction of the mop head 1, thereby shortening the distance between the hanging teeth 54 at both ends. After releasing the driving part 6, the return spring member 7 pushes the first movable plate 51 and the second movable plate 52 to move away from each other along the length direction of the mop head 1, causing the hanging teeth 54 at both ends to move away from each other and restoring the connection state with the hanging sleeves 13 of the mop cloth.

[0049] As Figures 2 to 5 shown, in a preferred embodiment, the driving part 6 includes a knob 62. A connecting hole 31 is provided on the cover plate 3. The gear 61 is fixedly connected to the knob 62 through the connecting hole 31, and the knob 62 is rotatably arranged on the cover plate 3. When the knob 62 is rotated, the gear 61 rotates simultaneously. At this time, the first rack 511 and the second rack 521 meshing with the gear 61 move relative to each other along the length direction of the mop head 1, that is, the first movable plate 51 and the second movable plate 52 move relative to each other and approach. In this way, the distance between the hanging teeth 54 at both ends of the movable plate is shortened and disengages from the hanging sleeve 13, realizing quick disassembly.

[0050] In another preferred embodiment, as Figures 6 to 9 shown, the driving part 6 includes a slider 63 and a push button 64. A connecting hole 31 is provided on the cover plate 3. The slider 63 is fixedly connected to the push button 64 through the connecting hole 31; the push button 64 is slidably arranged on the cover plate. The slider 63 is fixedly connected to the first movable plate 51. Preferably, the slider 63 and the first movable plate 51 are integrally formed. Pushing the push button 64 drives the first movable plate 51 to move towards the second movable plate 52. The first rack 511 moves towards the second movable plate 52. At this time, the second rack 521 meshing with the first rack 511 through the gear 61 drives the second movable plate 52 to move, that is, the first movable plate 51 and the second movable plate 52 move relatively closer. In this way, the distance between the hanging teeth 54 at both ends of the movable plate is shortened and disengages from the hanging sleeve 13, realizing quick disassembly. Further, a positioning shaft 41 and / or a positioning post are provided on the bottom plate 4 and / or the cover plate 3. The gear 61 is rotatably arranged on the positioning shaft 41 to prevent the gear 61 from moving with the first rack 611 and unable to transmit power; a long slot 523 cooperating with the positioning shaft 41 is provided on the second movable plate 52 or the first movable plate 51. In this way, during the relative movement of the second movable plate 52 or the first movable plate 51, there will be no interference with the positioning shaft 41. Further still, two first racks 511 are provided on the first movable plate 51, and two second racks 521 are provided on the second movable plate 52. Gears 61 are meshed between the first rack 511 and the second racks. The slider 63 is a rectangular protrusion, and the push button 64 is inserted and fixed on the rectangular protrusion to prevent relative sliding between the push button 64 and the slider 63. The slider 63 can slide in the connecting hole 31.

[0051] As Figures 3 to 9As shown, in a preferred case, the reset spring 7 includes two groups of reset springs, which are arranged on both sides of the gap between the first movable plate 51 and the second movable plate 52, so that the force between the first movable plate 51 and the second movable plate 52 is balanced. The reset spring includes a first spring 71, a positioning column 53 is provided on the side of the first movable plate 51 away from the hanging tooth, and a first positioning groove 32 is provided on the cover plate 3 or the bottom plate 4. One end of the first spring 71 is fixed on the positioning column 53 of the first movable plate 51 and the other end is fixed in the first positioning groove 32. In this way, when the first movable plate 51 and the second movable plate 52 are relatively close, only the end of the first spring 71 connected to the positioning column 53 is compressed, so that the movement of the first movable plate 51 and the second movable plate 52 is smoother and more stable. Further, the reset spring also includes a second spring 72, and the first spring 71 and the second spring 72 are arranged longitudinally along the length direction of the mop head 1. A positioning column 53 is provided on the side of the second movable plate 52 away from the hanging tooth 54, and a second positioning groove 33 is provided on the cover plate 3 or the bottom plate 4. One end of the second spring 72 is fixed on the positioning column 53 of the second movable plate 52 and the other end is fixed in the second positioning groove 33. In this way, the return springs of the first movable plate 51 and the second movable plate 52 are relatively independent, and the movement is smoother and more stable.

[0052] In a preferred case, the cover plate 3 and the bottom plate 4 are fixed together by any means or any combination of snap connection, screw connection, plug connection, and gaps are provided at both ends of the bottom plate 4 and the cover plate 3, and the hanging teeth 54 are exposed from the gaps. The plate between the hanging teeth 54 and the first movable plate 51 and / or the second movable plate 52 is thinned to form a bending mark 55, and the hanging teeth 54 can be bent from the bending mark 55 to facilitate connection with the mop. Further, the hanging teeth 54 are integrally formed with the first movable plate 51 and / or the second movable plate 52. In another embodiment, the hanging teeth 54 are connected to the first movable plate 51 and / or the second movable plate 52 by soft glue, and the soft glue facilitates the hanging teeth 54 to be lifted up from the first movable plate 51 and / or the second movable plate 52 and connected to the mop. A first latching tongue 541 is provided on the hanging tooth 54 at one side close to the cover plate 3, a supporting edge 34 is provided on the cover plate 3, and a latching protrusion 35 cooperating with the first latching tongue 541 is provided on the supporting edge 34. In this way, when hanging the mop 12, the hanging teeth 54 are bent from the bending marks 55 to approach each other, which is convenient for hanging the mop 12. Then, the hanging tooth 54 is pressed toward one side of the cover plate 3 to make the first latching tongue 541 and the latching protrusion 35 engage and fix each other, thereby forming a fixed limit for the hanging tooth 54. At the same time, the supporting edge 34 prevents the hanging tooth 54 from transitionally bending toward the side of the cover plate 3, which causes the two ends of the mop 12 to curl up, so that the mop 12 has a better cleaning effect.

[0053] In a preferred embodiment, a plurality of connecting members 10 are provided on one side of the first movable plate 51 and the second movable plate 52 close to the bottom plate 4. Preferably, the connecting members 10 are magic tapes, and the magic tapes are evenly arranged on the first movable plate 51 and the second movable plate 52. Through holes 44 are provided on the bottom plate 4 corresponding to the connecting members 10. The upper surface of the mop is a hook-and-loop fabric or is provided with a magic tape. The connecting members 10 pass through the through holes 44 and are adhesively connected to the upper surface of the mop 12. When the driving part 6 is rotated or pushed to drive the first movable plate 51 and the second movable plate 52 to move, the connecting members 10 are misaligned with the through holes 44 and will be hidden in the bottom plate 4, so that the mop 12 is automatically separated from the connecting members 10. When the return spring 7 pushes the first movable plate 51 and the second movable plate 52 to extend, at the same time, the positions of the connecting members 10 and the through holes 44 are aligned, that is, the connecting members 10 can always be exposed from the through holes 44, and the mop 12 is laid flat on the bottom plate 4 and connected or adhered to the connecting members 10, realizing the fixed installation of the mop 12.

[0054] In a preferred embodiment, as Figures 3 to 9 shown, the first movable plate 51 and the second movable plate 52 are provided with linear chutes 56. Preferably, four chutes 56 are provided, and the four chutes 56 are evenly distributed on the movable plate. The chutes 56 are arranged along the length direction of the mop head 1. The cover plate 3 is provided with guide grooves 36. The chutes 56 are sleeved outside the guide grooves 36 and slide along the guide grooves 36. The guide grooves 36 and the chutes 56 limit the position between the movable plate 5 and the cover plate 3, so that the first movable plate 51 and the second movable plate 52 can only slide along the length direction of the mop head 1 to avoid misalignment. Further, the chutes 56 and the guide grooves 36 can also jointly form the first positioning device of the movable plate 5, that is, when the driving part 6 is pushed or rotated to remove the cloth, one end of the chute 56 close to the hanging teeth 54 contacts the guide groove 36, restricting the first movable plate 51 and the second movable plate 52 from approaching each other continuously, resulting in permanent deformation of the return spring due to excessive compression. When the return spring 7 resumes deformation, the end of the chute 56 far from the hanging teeth 54 contacts the guide groove 36, restricting the first movable plate 51 and the second movable plate 52 from moving away from each other continuously and disengaging from the mop head 1.

[0055] In another preferred case, a plurality of second lugs 42 are provided on the bottom plate 4, and card holes 37 adapted to the second lugs 42 are provided on the cover plate 3. The bottom plate 4 is fixedly connected to the cover plate 3 by clamping the second lugs 42 in the card holes 37. Long strip-shaped sliding holes 561 are provided on the first movable plate 51 and the second movable plate 52, and the second lugs 42 pass through the sliding holes 561. In this way, when the first movable plate 51 and the second movable plate 52 move relative to each other, they will not interfere with the second lugs 41. At the same time, the second lugs 42 and the sliding holes 561 together form a second positioning device for the first movable plate 51 and the second movable plate 52, that is, when the driving part 6 is pushed or rotated to unload the cloth, the end of the sliding hole 561 close to the hanging teeth contacts the second lug 42, restricting the first movable plate 51 and the second movable plate 52 from approaching each other further, and avoiding the problem that the return spring is over-compressed and undergoes permanent deformation. When the return spring 7 resumes deformation, the end of the sliding hole 561 away from the hanging teeth 54 contacts the second lug 42, restricting the first movable plate 51 and the second movable plate 52 from moving away from each other further and disengaging from the mop head 1, thereby realizing the limit of the first movable plate 51 and the second movable plate 52, and also enabling positioning between the first movable plate 51 and the second movable plate 52 and the bottom plate 4. Further, the card holes 37 are provided on the side wall of the guiding groove 36, and the sliding holes 561 are provided at the bottom of the sliding groove 56.

Further, a notch is provided on the side wall of the connecting head 8 to form a clamping groove 85, and there is an elastic clamping member on the mop rod 2. When the mop rod 2 is parallel to the mop head 1, the elastic clamping member is clamped in the clamping groove 85, so that the mop head 1 is fixedly parallel on the mop rod 2, which is convenient for the storage and cleaning of the mop. When it is necessary to use the mop head for cleaning, rotate the mop head 1, and the elastic clamping member will be disengaged from the clamping groove 85.

[0060] In the above technical solution, when it is necessary to wash or replace the mop cloth 12, rotate or push the driving part 6, the first movable plate 51 and the second movable plate 52 move closer to each other so that the hanging teeth 54 at both ends retract, and at the same time drive the connecting member 10 to move out of alignment with the through hole 44. The hanging teeth 54 are disengaged from the hanging sleeve 13, and the connecting member 10 is separated from the upper surface of the mop cloth 12, and the mop cloth 12 is automatically separated from the mop head 1, realizing the automatic disassembly of the mop cloth 12 without the need to touch the dirty mop cloth with hands at all. After the mop cloth 12 is automatically disassembled, release the driving part 6, and the return spring 7 restores its deformation and pushes the first movable plate 51 and the second movable plate 52 away from each other, so that the hanging teeth 54 protrude and the connecting member 10 is exposed from the through hole 44 and keeps the connecting member 10 aligned with the through hole 44, avoiding the first movable plate 51 and the second movable plate 52 from retracting under external force. At this time, the end of the sliding groove 56 away from the hanging teeth 54 contacts the guiding groove 36 and / or the end of the sliding hole 561 away from the hanging teeth 54 contacts the second tongue 42. Then bend the hanging teeth 54 to facilitate hanging the hanging sleeve 13 on the hanging teeth 54, and then press the hanging teeth 54 towards the cover plate 3 side, so that the first tongue 541 is clamped and fixed on the convex, and the installation of the mop cloth 12 is completed, and the operation method is simple and convenient.
