Description

Technical Field

[0001] This utility model relates to the field of mop technology, specifically a mop head and its corresponding plywood mop. Background Technology

[0002] Sponge mops are a common cleaning tool in homes and offices. They are highly absorbent, made of polyvinyl alcohol (PVA) sponge with a textured bottom that allows for rapid absorption of large amounts of water and dirt—up to 10 times the water absorption of a regular sponge. This makes them especially suitable for heavy water stains and slippery floors in kitchens and bathrooms. They are powerful yet leave no water stains; the strong absorbency of the PVA material effectively removes dirt and leaves minimal water residue, keeping even glossy tiles and wooden floors clean and streak-free. They are also easy to use, requiring no hand washing. Most sponge mops come with a folding or roller wringing design, eliminating the need for hand wringing. Simply push, pull, or press to quickly remove water, making them more hygienic and effortless to use. Furthermore, sponge mops can be rinsed directly with water, making cleaning and maintenance convenient.

[0003] However, it also has some drawbacks. It is easy to harden and requires frequent maintenance. The cotton pad will harden after drying for a long time and needs to be soaked in advance or rinsed repeatedly to soften it before use. Long-term soaking may cause mold and odor. It has poor durability and the cotton pad is easy to wear and crack, especially after frequent squeezing or collision. It needs to be replaced regularly (about 3-6 months). While current clip-on mops are convenient for wringing out water, the mop heads are difficult to replace, making the process arduous. For example, when installing the mop head, the unlocking mechanism must be pressed to reinstall it; it doesn't automatically lock after installation, making one-handed replacement impossible. Furthermore, the mop head, made of plywood, is fixed to a rigid, sheet-like structure, which can bend over time, increasing stress on the fixing points. Traditional fixing methods make it difficult to remove deformed mop heads, requiring forceful pulling with one hand – unhygienic and laborious. Additionally, current replaceable mop heads are not securely fixed, leading to accidental drops due to accidental activation of the replacement switch, and they wobble during use, further hindering usability. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a mop head.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A mop head includes a fixed base and a mop head body. One or more mop head fixing plates are fixed to the fixed surface of the mop head body. Each mop head fixing plate has multiple fixing posts fixed to its fixed surface. Each fixing post has a limiting groove recessed into the same curved surface. A sliding cavity is provided inside the mop head body along the length of the mop head body. A limiting push plate is slidably arranged inside the sliding cavity. A spring is provided at one end of the sliding cavity to elastically push the limiting push plate. Each fixing post is inserted into the sliding cavity of the fixed base. In normal operation, the spring causes the corresponding edge of the limiting push plate to be inserted into the limiting groove of the corresponding fixing post. The extension and retraction direction of the spring is the same as the reciprocating direction of the limiting push plate. A tapered guide structure is provided at the insertion end of each fixing post.

[0006] Furthermore, each limiting push plate has a push plate perpendicular to its body at one end, the push plate passing through the long strip sliding opening of the fixed base and extending to the outside of the fixed base.

[0007] Furthermore, the mop head fixing plate is symmetrically arranged on the left and right, and the fixing base is divided into left and right parts, and the left and right parts are respectively rotatably connected to the rotating fixing seat in the middle part.

[0008] Furthermore, the side of the sliding cavity near the mop head fixing plate is an open structure, and a cover plate is fixedly placed on the open structure, with each fixing post penetrating through the cover plate.

[0009] Furthermore, each limiting push plate has an I-shaped structure, and the mop head fixing plate on each side has three fixing posts. The bottom edge of the I-shaped structure of each limiting push plate is located in the limiting groove of the corresponding three fixing posts.

[0010] This utility model also relates to a plywood mop, including the above-mentioned mop head and mop handle. The mop head body is made of plywood. The mop handle is vertically fixed to a rotating fixed base. A V-shaped squeezing arm is fitted on the mop handle. The middle part of the squeezing arm is sleeved on the mop handle. The two ends of the squeezing arm are rotatably connected to the left and right parts of the fixed base on each side by hinges.

[0011] Furthermore, the mop handle above the extrusion arm is rotatably equipped with an extrusion handle. The rotation direction of the extrusion handle is perpendicular to the plane where the V-shaped extrusion arm is located. The extrusion handle is rotatably equipped with an extrusion push rod, and the other end of the extrusion push rod is rotatably connected to the middle part of the extrusion arm.

[0012] Furthermore, a C-shaped buckle is fixed to the side of the squeeze handle near the mop handle, and the buckle is locked onto the mop handle when the base is unfolded.

[0013] Furthermore, the mop handle is fitted with an anti-slip sleeve, and a hanging ring is provided at the top of the mop handle.

[0014] When replacing the mop head body, the movable push plate moves the limiting push plate, causing the limiting push plate on each side to separate from the limiting groove of the corresponding fixing post, so that the fixing post is no longer obstructed, thus facilitating the separation of the mop head body from the fixing base and making it convenient to replace the mop head body. When fixing the new mop head body, the fixing post is inserted into the corresponding hole on the fixing base, and the push plate and limiting push plate are released. Under the action of the return spring, the limiting push plate is reinserted into the corresponding fixing post limiting groove, thereby re-locking each fixing post and completing the fixing of the mop head body.

[0015] It also allows for one-handed mop head replacement and automatic locking of the mop head after replacement. Because the extension and retraction direction of the return spring is the same as the reciprocating direction of the limit push plate, and each fixed post has a tapered guide structure at its insertion end, the fixed post is easily inserted into place through the guide structure. As the fixed post is inserted, the inclined surface formed by the guide structure pushes the limit push plate to overcome the spring force of the return spring and move in the opposite direction. When the fixed post is fully inserted into the sliding cavity, the limit push plate, under the rebound action of the return spring, causes the edge to re-engage into the corresponding limit groove, thereby automatically locking the fixed post and then automatically locking the mop head body. In this way, when replacing the mop head, there is no need to press the unlocking structure to reinstall the mop head. After installation, the mop head can be automatically locked directly. Simply place the mop head on the ground, align the mounting hole on the fixed base with the fixed post, and then press down on the entire mop head body with one hand to insert the fixed post into place. This makes it convenient for one-handed operation and installation.

[0016] In addition, when disassembling the mop head, even if the mop head is bent and deformed, increasing the stress on the fixed part of the mop head, you can simply press and push the corresponding limit push plates on each side to completely separate the limit push plates from the fixed posts, which makes it easier to separate the fixed posts from the fixed base. This makes it easier to separate the mop head from the fixed base, and it is also simpler and less strenuous to disassemble.

[0017] In summary, the structure of this utility model is simpler and more practical. It not only facilitates quick and easy replacement of the mop head, but also allows for locking and fixing on both sides of the mop head body. With more and more secure fixing points, it effectively prevents the mop head from shaking during use. In addition, the unlocking structure, i.e., the push plate, is located at the mop head, making it less likely to be bumped when mopping the floor, effectively preventing accidental unlocking and falling of the mop head.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The following is a detailed description of this embodiment with reference to the accompanying drawings: Example

[0024] like Figure 1-3As shown, a mop head includes a fixed base 1 and a mop head body 2. One or more mop head fixing plates 3 are fixed to the fixing surface of the mop head body 2. Each mop head fixing plate 3 has multiple fixing posts 4 fixed to its fixing surface. Each fixing post 4 has a limiting groove 5 recessed into its curved surface on the same side. A sliding cavity 6 is provided inside the mop head body 2 along its length. A limiting push plate 7 is slidably disposed inside the sliding cavity 6. A return spring 8 is provided at one end of the sliding cavity 6 to elastically push the limiting push plate 7. Each fixing post 4 is inserted into the sliding cavity 6 of the fixed base 1, and in the normal state, the return spring 8 keeps the limiting push plate 7 in place. The corresponding edges are inserted into the limiting grooves 5 of the corresponding fixing posts 4. The extension and retraction direction of the spring 8 is the same as the direction of the back and forth movement of the limiting push plate 7. Each fixing post 4 has a tapered guide structure at its insertion end. This guide structure at the insertion end of the fixing post 4 makes it easy to insert the fixing post 4 into place. As the fixing post 4 is inserted, the inclined surface formed by the guide structure pushes the limiting push plate 7 to move in the opposite direction against the elastic force of the spring 8. When the fixing post 4 is fully inserted into the sliding cavity 6, the limiting push plate 7, under the rebound action of the spring 8, causes the edge to re-engage into the corresponding limiting groove 5, thereby automatically locking the fixing post 4 and thus automatically locking the mop head body 2.

[0025] To facilitate the movement of each limiting push plate 7, each limiting push plate 7 has a push plate 9 perpendicular to its body at one end. The push plate 9 passes through the elongated sliding opening 10 of the fixed base 1 and extends to the outside of the fixed base 1. Thus, when it is necessary to push the limiting push plate 7 to unlock the fixed column 4, the push plate 9 can be moved.

[0026] To facilitate use with clip-on mops, the mop head fixing plate 3 is symmetrically arranged on the left and right sides, and the fixing base 1 is divided into left and right parts, and the left and right parts are respectively rotatably connected to the rotating fixing base 11 in the middle part.

[0027] To facilitate assembly and installation, the side of the sliding cavity 6 near the mop head fixing plate 3 is an open structure, and a cover plate 12 is fixedly covered on the open structure, with each fixing post 4 penetrating through the cover plate 12.

[0028] To further ensure the stability of the fixation, each limiting push plate 7 is an I-shaped structure, and each mop head fixing plate 3 on each side has three fixing posts 4. The bottom edge of the I-shaped structure of each limiting push plate 7 is located in the limiting groove 5 of the corresponding three fixing posts 4, that is, each mop head fixing plate 3 on each side can form a three-point fixation.

[0029] When the mop head needs to be replaced, i.e., the mop head body 2, the moving push plate 9 pushes the limiting push plate 7 to move, so that the limiting push plate 7 on each side separates from the limiting groove 5 of the corresponding fixing post 4, so that the fixing post 4 is no longer obstructed, thus making it easy to separate the mop head body 2 from the fixing base 1, and making it convenient to replace the mop head body 2. When fixing the new mop head body 2, the fixing post 4 is inserted into the corresponding insertion hole on the fixing base 1, and the push plate 9 and the limiting push plate 7 are released. Under the action of the return spring 8, the limiting push plate 7 is reinserted into the corresponding fixing post 4 limiting groove 5, thereby re-locking each fixing post 4 to complete the fixing of the mop head body 2. Example

[0030] like Figure 1-3 As shown, a type of PVC-coated mop includes a mop head and a mop handle 13. The mop head body 2 is made of PVC-coated cotton. The mop handle 13 is vertically fixed to a rotating base 11. A V-shaped squeezing arm 14 is fitted onto the mop handle 13. The middle part of the squeezing arm 14 is sleeved onto the mop handle 13. The two ends of the squeezing arm 14 are rotatably connected to the left and right parts of the fixed base 1 on each side via hinges 15. A squeezing handle 16 is rotatably mounted on the mop handle 13 above the squeezing arm 14. The rotation of the squeezing handle 16... The direction is perpendicular to the plane where the V-shaped squeezing arm 14 is located. The squeezing handle 16 is rotatably equipped with a squeezing push rod 17. The other end of the squeezing push rod 17 is rotatably connected to the middle part of the squeezing arm 14. A C-shaped buckle 18 is fixed on the side of the squeezing handle 16 near the mop handle 13. When the fixed base 1 is unfolded, the buckle 18 is locked on the mop handle 13. The mop handle 13 is also covered with an anti-slip sleeve. A hanging ring 19 is set at the top of the mop handle 13. It is like the current clamp mop, except that the structure of the mop head is different.

[0031] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
