[0001] This utility model relates to the field of household appliances technology, and in particular to the cotton head disassembly and assembly structure of a folding mop head. Background Technology

[0002] The applicant has applied for a Chinese utility model patent entitled "Folding and Squeezing Foamed Mop" with patent number ZL202123135543.9 (publication number CN 217827745 U), which discloses a folding and squeezing foamed mop, including a mop handle, a folding mop head with foamed cotton, and a wringing frame. The folding mop head is movably connected to the lower end of the mop handle. An adapter is snapped into the lower end of the mop handle. The folding mop head includes a central plate and two folding plates. The top of the central plate has an upwardly protruding connecting part, which is hinged in the connecting groove at the lower end of the adapter and can only swing left and right. The two folding plates are respectively hinged to opposite sides of the central plate. An elastic element is provided between the folding plates and the central plate to keep the folding plates in an unfolded position. Foamed cotton is connected to the bottom surface of the folding plates. The foam is connected to the bottom of the folding board by a plug-in method. A back panel is glued to the foam, and the back panel has buckles. The bottom of the folding board has a buckle groove that matches the buckles.

[0003] During the insertion of the snap fastener into the slot, the insertion process is often difficult due to processing errors. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an easy-to-disassemble foldable mop head cotton head assembly and disassembly structure, based on the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a detachable structure for a foldable mop head, comprising a central plate; two folding plates, respectively hinged to opposite sides of the central plate, each folding plate having a snap groove on its bottom surface, the snap groove having a first insertion interface; two back plates, fixed to the top surface of the foamed mop head at intervals, the back plates having snaps that can be inserted into the first insertion interface and cooperate with the snap groove; the inlet diameter of the snap groove is larger than the inner diameter of the snap groove.

[0006] Preferably, a first mating surface is provided on the bottom wall of the buckle groove, and a second mating surface corresponding to the first mating surface is provided on the buckle. At least one of the first and second mating surfaces is an inclined surface, which is inclined upward toward the direction in which the buckle slides into the buckle groove. Since the bottom wall of the buckle groove or the buckle is provided with an inclined surface that gradually slopes downward toward the connection between the two folded plates, when the middle of the foam is grasped by hand and pulled outward, the buckles on the left and right sides of the back plate slide along the inclined surface toward the middle of the foam, so that the buckles on the left and right sides of the back plate simultaneously disengage from the corresponding buckle groove, making removal convenient and quick; and the inclined surface either increases the diameter of the first insertion interface or reduces the volume of the buckle insertion end, thereby facilitating the insertion of the buckle into the buckle groove.

[0007] Preferably, the first mating surface is a first inclined surface that gradually slopes upward toward the direction in which the buckle slides into the buckle groove; the second mating surface is also a second inclined surface that gradually slopes upward toward the direction in which the buckle slides into the buckle groove. In other embodiments, the first mating surface may be a plane and the second mating surface may be an inclined surface, or the first mating surface may be an inclined surface and the second mating surface may be a plane.

[0008] Preferably, the buckle is L-shaped, comprising a first vertical portion extending upward from the back plate and a first horizontal portion extending horizontally from the first vertical portion. The lower surface of the first horizontal portion is provided with the aforementioned second inclined surface. The first horizontal portion can be inserted into the first insertion interface such that the first inclined surface and the second inclined surface cooperate. This design facilitates the insertion of the outwardly protruding first horizontal portion into the buckle groove.

[0009] Preferably, each of the folding panels has at least one pair of fastening slots on its bottom surface, with the pair of fastening slots respectively located on both sides of the center line of the folding panel; the back panel has at least one pair of corresponding snap fasteners. This design increases the strength of the connection between the folding panel and the back panel.

[0010] Preferably, a second insertion interface is provided on the side of the buckle groove near the center line of the folding plate; the first horizontal part can enter the buckle groove from either the first insertion interface or the second insertion interface. With this design, the buckle groove has a larger opening, facilitating the entry of the first horizontal part into the buckle groove. Simultaneously, the opposing arrangement of each pair of buckle grooves makes it less likely for the buckle to detach from the second insertion interface; and the opposing buckle grooves on the two movably connected folding plates further prevent the buckle from detaching from the first insertion interface.

[0011] Preferably, the lower surface of the folding plate is provided with an L-shaped rib, the L-shaped rib including a second vertical portion extending downward from the lower surface of the folding plate and a second horizontal portion extending laterally from the bottom end of the second vertical portion, the L-shaped rib forming the fastening groove.

[0012] The lower surface of the folding plate is provided with two reinforcing ribs arranged along the length of the folding plate. The two reinforcing ribs are respectively located on both sides of the center line of the folding plate. The L-shaped protrusion is located on the side wall of the reinforcing rib near the center line of the folding plate. The reinforcing rib and the L-shaped protrusion together form the retaining groove. When the mop head mops the floor, it will be subjected to a thrust perpendicular to the length of the folding plate. This thrust can damage the retaining groove structure. By adopting the above solution, the reinforcing rib can increase the strength of the retaining groove structure.

[0013] Preferably, a connecting rib is provided between the upper ends of the second vertical portions of the two reinforcing ribs.

[0014] Preferably, each of the folding panels has two pairs of fastening grooves on its bottom surface, and the back panel has two pairs of corresponding fasteners. This design increases the strength of the connection between the folding panels and the back panel.

[0015] Preferably, the angle between the first inclined surface and the horizontal plane is 10 to 35 degrees. This angle design ensures the stability of the buckle slot and the snap fastener connection, thus preventing the back panel from falling off the folding plate.

[0016] Preferably, the upper surface of the folding plate is provided with a protruding strip extending away from the central plate. This design facilitates the folding of the upper surface of the folding plate into the squeezing cylinder near the central plate end, and the protruding strip abuts against the cylinder after the folding plate enters, resulting in a stronger fold and better squeezing effect.

[0017] Compared with the prior art, the advantages of this utility model are: the inlet port diameter of the buckle groove is larger than the inner end diameter of the buckle groove, which is conducive to the buckle and the slot overcoming processing errors for assembly.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-6 The diagram shows a preferred embodiment of the detachable mop head structure of the present invention. The detachable mop head structure is located below the mop handle 100. The detachable mop head structure includes a central plate 4, two folding plates 1 respectively hinged to opposite sides of the central plate 4, and two back plates 2 respectively connected to the bottom of the two folding plates 1. The connection method between the central plate 4 and the folding plates 1 is detailed in the prior art.

[0026] The ends of the two folding plates 1 are connected to each other, and the two folding plates 1 can be folded along the connection point of the two folding plates 1. The bottom surface of each folding plate 1 is provided with two pairs of fastening slots 11, and the two fastening slots 11 in each pair are respectively located on both sides of the center line 1a of the folding plate. The fastening slot 11 has a first insertion interface 11a facing the connection point of the two folding plates 1 and a second insertion interface 11b facing the center line 1a of the folding plate. The bottom wall of the fastening slot 11 is provided with a first inclined surface 111, which gradually slopes downward toward the first insertion interface 11a, or in other words, the first inclined surface slopes upward toward the direction in which the fastener slides into the fastening slot.

[0027] like Figures 3-5 As shown, in this embodiment, the bottom surfaces of both folding plates 1 are provided with two reinforcing ribs 12 arranged along the length of the folding plate 1. The two reinforcing ribs 12 are respectively located on both sides of the center line 1a of the folding plate. On the side wall of each reinforcing rib 12 near the center line 1a of the folding plate, an L-shaped protrusion rib 13 extends toward the center line 1a of the folding plate. The L-shaped protrusion rib 13 includes a second vertical part 131 and a second horizontal part 132 connected to the bottom end of the second vertical part 131. In this embodiment, the reinforcing rib 12 and the L-shaped protrusion rib 13 together constitute the aforementioned groove 11. When the mop head mops the floor, it will be subjected to a thrust perpendicular to the length of the folding plate 1. This thrust will damage the structure of the groove 11, and the design of the reinforcing rib 12 can increase the strength of the groove 11 structure. In addition, a connecting rib 14 is provided between the upper ends of the second vertical part 131 on the two reinforcing ribs 12.

[0028] like Figure 3 , 6As shown, foam 3 is bonded to the lower surface of the back panel 2, and a snap fastener 21 that mates with the snap groove 11 is provided on the upper surface of the back panel 2. The snap fastener 21 is L-shaped and includes a first vertical portion 211 extending upward from the back panel 2 and a first horizontal portion 212 extending from the upper end of the first vertical portion 211 in a direction away from the center line of the back panel 2. A second inclined surface 212a that mates with the first inclined surface 111 is provided on the lower surface of the first horizontal portion 212. The second inclined surface is inclined upward in the direction in which the snap fastener slides into the snap groove. The first horizontal portion 212 can enter the snap groove 11 from either the first insertion interface 11a or the second insertion interface 11b, so that the first inclined surface 111 and the second inclined surface 212a mate. The aforementioned buckle slot 11 is provided with a first insertion interface 11a and a second insertion interface 11b, which makes the buckle slot 11 more open, making it easier for the first horizontal part 212 to enter the buckle slot 11. At the same time, since each pair of buckle slots 11 is arranged opposite to each other, the buckle 21 is not easy to fall off from the second insertion interface 11b; and since the two movable folding plates 1 are provided with opposite buckle slots 11, the buckle 21 is not easy to fall off from the first insertion interface 11a.

[0029] In other embodiments, replacing one of the first inclined surface 111 and the second inclined surface 212a with a flat surface can also achieve the technical effect of easy disassembly of the back panel 2. In addition, the angle between the inclined surface and the horizontal plane is 20 to 35 degrees. The above-mentioned angle design ensures the stability of the connection between the buckle groove 11 and the buckle 21, thereby preventing the back panel 2 from falling off the folding plate 1.

[0030] A raised strip 15 is provided on the upper surface of the folding plate 1 at the end away from the central plate 4. The raised strip 15 extends in a direction away from the central plate 4. With the above solution, it is beneficial for the upper surface of the folding plate 1 to be folded into the squeezing cylinder 5 at the end near the central plate 4. After the folding plate 1 enters the squeezing cylinder 5, the raised strip 15 abuts against the squeezing cylinder 5, making the folding degree of the folding plate 1 stronger and the squeezing effect better.

[0031] When assembling the cotton head disassembly and assembly structure of the folding mop head, grasp the foam 3 on the lower surface of the back plate 2, align the upper surface of the back plate 2 with the lower surface of the folding plate 1, slide the left side of the back plate 2 to the left, so that the buckle 21 on the left side of the back plate 2 enters the buckle groove 11 of the left folding plate 1 from the first insertion interface 11a. Then slide the right side of the back plate 2 to the right, so that the buckle 21 on the right side of the back plate 2 enters the buckle groove 11 of the right folding plate 1 from the first insertion interface 11a, thereby achieving the connection between the back plate 2 and the folding plate 1.

[0032] When disassembling the cotton head of the folding mop head, grasp the middle of the foam 3 on the lower surface of the back plate 2 and pull it outward. The buckles 21 on the left and right sides of the back plate 2 will slide along the first inclined surface 111 on the bottom wall of the buckle groove 11 toward the middle of the foam 3, so that the buckles 21 on the left and right sides of the back plate 2 will disengage from the corresponding buckle groove 11 at the same time, making disassembly convenient and quick.
