Description

Technical Field

[0001] The utility model belongs to the technical field of collodion mops, in particular to a collodion mop with a quick-detachable cotton head. Background Art

[0002] Collodion mops are highly absorbent, ensuring the cotton head's ability to fully clean, making them popular with consumers. Their greatest feature is that while they retain the self-cleaning properties of a wringing mop, the mop head is made of polyvinyl alcohol (PVA) collodion, which has strong water absorption and ensures the mop head's ability to fully clean. While collodion mops play an important role in household cleaning, their cotton heads need to be replaced after a period of use. The typical replacement method involves holding the cotton head and removing it from the mop head.

[0003] To facilitate quick removal of the cotton head, a new type of quick-release cotton mop has emerged. For example, Chinese patent CN202322720181.2 discloses a novel quick-change cotton mop, comprising a mop rod, a fork bracket, and a water-squeezing plate rotatably connected to the fork bracket. The mop rod is provided with a pulling mechanism for driving the water-squeezing plate to flip. The mop also includes a strip-shaped, flexible cotton head, the cotton head having at least two adhesive plates, each of which is provided with a pair of main hooks. A pair of main connecting plates are provided at the bottom of the water-squeezing plate. The pair of main connecting plates are open toward opposite sides, and the side of the main connecting plate facing the inside of the cotton head is also open. The main connecting plates and the main hooks are mutually engaged and slidably engaged. The water-squeezing plate is provided with a sliding channel, a slider is provided in the sliding channel, and a push plate and a first drive plate are provided on the slider. The adhesive plate is provided with a push plate, and the first drive plate is located outside the push plate and is used to push the push plate. This patented product can realize quick installation and removal of the cotton head, but it also has certain shortcomings: when the cotton head is dry, the cotton head cannot be removed / is difficult to remove; its removal requires pushing the adhesive plate above the cotton head to move and separate from the main clamping plate, which means that the cotton head needs to be deformed during the removal process. As we all know, once the cotton head is dry, its hardness is relatively large and it is not easy to deform, which makes it difficult to remove the cotton head. Summary of the Invention

DETAILED DESCRIPTION

[0036] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1-14 As shown:

[0037] A collodion mop with a quick-detachable cotton head comprises a mop rod 1 and a mop head 2, wherein a cotton head 20 is fixedly provided on the mop head 2; the mop head 2 comprises a middle seat 21 and plywood 22 hinged on both sides of the middle seat 21; a fork head 3 is provided at the end of the mop rod 1, and two plywood 22 are rotatably arranged at both ends of the fork head 3; a handle 4 is hinged on the mop rod 1, and the handle 4 and the middle seat 21 are connected by a connecting rod 42, which can be an independent component or integrally formed in the middle seat 21. When the handle 4 is pulled, the middle seat 21 moves toward the middle of the fork head 3, and the plywood 22 on both sides converge and squeeze the cotton head 20. The water squeezing method of the collodion mop is a simple technology in the industry. The user only needs to pull the handle 4 to fold the mop head 2 to squeeze water, and release the handle 4, and the mop head 2 remains in a flat state, which is the mopping state. The cotton head 20 is fixedly provided with a clamping piece 201, and the clamping piece 201 is provided with a plurality of first hooks 2011; a movable seat 23 is slidably provided in the clamping plate 22, and the movable seat 23 is provided with a second hook 232 that cooperates with the first hook 2011 of the clamping piece; an elastic member is provided on the clamping plate 22, and the elastic member gives the movable seat 23 a force and allows the first hook 2011 and the second hook 232 to bite, and a pushing part 231 is provided on the upper end of the movable seat 23 to push the push part. The movable portion 231 and the movable seat 23 move, separating the first hook 2011 and the second hook 232, allowing the cotton head 20 to be removed from the mop head 2. During the removal process, the cotton head does not deform, allowing it to be removed even when it is dry and hardened. The clamping plate 22 is provided with a transverse notch 2222 that limits the movement of the first and second hooks. The transverse notch 2222 limits and guides the first and second hooks 2011, 232. There are at least two ways to install the cotton head 20: First, the user presses the push portion of the movable seat to unlock it, then aligns the first hook of the cotton head engaging piece with the transverse notch. Finally, the movable seat is released, and the first and second hooks engage under the action of the elastic member. Method 2: Without driving the movable base, first place one of its clips into the horizontal slot, then push the cotton head / clip to engage the first hook with the second hook. Then, place the other clip into the horizontal slot, then push the cotton head / clip to engage the first hook with the second hook. Both installation methods are acceptable, and the user can choose the method for installing the cotton head according to their actual needs. The elastic member is preferably a spring, soft rubber, or other component.

[0038] The clamping plate 201 is provided with at least two groups of first hooks 2011 along the length of the cotton head, each group having two first hooks 2011 with hook bodies facing in opposite directions. The clamping plate is a commonly used component on the market, and is provided with four first hooks on the clamping plate, with the hook bodies of the first hooks facing outwards on both sides. The structure of the present application does not require a customized clamping plate, and commonly used clamping plates on the market can be used, which has strong adaptability and reduces the manufacturer's production costs.

[0039] The transverse notch 2222 is provided with a constriction 2223 on the outer side. When the first hook 2011 and the second hook 232 engage, they fit tightly within the constriction 2223. The constriction is where the first and second hooks engage. This constriction reduces the gap between the first and second hooks, allowing for a tighter fit and a more stable connection. A guiding slope is provided at the constriction to facilitate the first hook's entry and exit. Furthermore, the separation between the first and second hooks is wide, facilitating installation and removal of the cotton tip.

[0040] The splint 22 includes a first plate body 222 and a second plate body 221 that slide relative to each other. The first plate body 222 is rotatably connected to the middle seat 21, and the second plate body 221 is rotatably connected to the fork head 3. The second plate body 221 can be integrally provided with a connecting seat 2211, which is hinged to the fork head 3 through the connecting seat 2211, or a connecting seat of an independent component can be hinged to the second plate body, with one end of the connecting seat hinged to the fork head and the other end hinged to the second plate body. Whether the connecting seat is an integrated component or an independent component is decided by the manufacturer. A transverse notch 2229 is provided on the first plate body 222, and a protrusion 2219 limited in the transverse notch 2229 is provided on the second plate body 221. When the collodion mop is squeezing water, the second plate body can move, thereby allowing the splint to extend, which can better squeeze water from the end of the cotton head and improve the squeezing effect. In the mopping state, the first plate body 222 and the second plate body 221 remain in a contracted state; the movable seat 23 is placed in the gap limited between the first plate body 222 and the second plate body 221, and the movable seat 23 is limited by the gap between the two, thereby ensuring the stability of the limited seat 23.

[0041] The first plate 222 is provided with a recessed portion 2221, within which the movable seat 23 moves. The second plate 221 at least partially covers the upper surface of the recessed portion 2221 and restricts the movable seat 23 from escaping from the recessed portion 2221. A transverse notch 2222 is located within the recessed portion 2221 of the first plate, and the engaging piece 201 is connected to the lower portion of the first plate 222. The recessed portion 2221 limits the movable seat 23, allowing it to move laterally within the recessed portion 2221.

[0042] The first plate 222 is provided with a spring limiting groove 2224, and the movable seat 23 is provided with a spring abutment seat 233. The spring abutment seat 233 can be extended into the spring limiting groove 2224, with one end of the spring abutting against the positioning column position of the spring limiting groove and the other end abutting against the positioning column position of the spring abutment seat. The spring abutment seat 233 is provided with a buckle, which can be engaged with the surface of the spring limiting groove 2224 and prevent the abutment seat from detaching from the first plate 222.
