Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a flat mop. Background Art

[0002] The mop is an important cleaning tool, and there are many forms of mops. However, the flat mop is chosen and used by more and more people because of its advantages such as economy, practicality, convenience and speed. The existing flat mops have roughly similar structures, generally consisting of a mop rod, a mop head and a mop cloth. The mop rod is hinged to the mop head and can rotate in different directions. The mop head adopts a flat design, and the mop cloth is installed flat on the bottom plate. The common mop head includes a bottom plate and a cover plate, and the bottom plate supports and fixes the wiping material. The convenience demand of the mop is also increasingly affecting the competitiveness of the product. The existing flat mop has the problem that it is not convenient to add cleaning liquid. For the ground, glass with more serious stains or when deep cleaning is required, only using a wet wiping material to wipe the ground obviously cannot achieve the purpose of deep cleaning. It is often necessary to first use a wet wiping material dipped in cleaning liquid to fully wipe the ground and foam it to form porous foam, so that the stains are initially dissolved or decomposed by the cleaning liquid, and then use the wiping material on the mop head to wipe the ground. Not only will a variety of tools be used, but the operation is also cumbersome, time-consuming and laborious. Or the cleaning liquid is directly sprinkled on the ground, and then wiped with a wipe to form porous foam, which not only wastes a lot of cleaning liquid, but also easily causes the user to slip and fall if not careful. There is also a flat mop with a liquid filling port at the fixed position of the dust removal paper. The cleaning liquid is added between the cover plate and the bottom plate through the liquid filling port, and then the cleaning liquid penetrates into the wipe. However, due to the lack of a fixed structure, the cleaning liquid flows arbitrarily on the upper surface of the bottom plate and cannot penetrate all of the wipe, causing waste, and the cleaning liquid on the upper surface of the bottom plate is not convenient to clean. In addition, this structure cannot add substances such as sterilization balls. Utility Model Content

Preferably, the fixing snap ring 8 is circular and arranged in the middle of the transparent cover 6, and snap rings 83 are provided around the fixing snap ring 8. A mounting hole is provided on the transparent cover 6, so that the snap ring 8 undergoes elastic deformation and enters the mounting hole, and then restores the elastic deformation to be snap-fitted and fixed to the edge of the mounting hole. In this way, cleaning agent can be conveniently added into the liquid storage tank 5 through the hollow portion 81. At the same time, when dust paper or clothes are used as wiping materials, the dust paper or clothes can be wrapped around the mop plate 2, and the edge of the dust paper or clothes can be inserted into the hollow portion 81. At this time, the strip hole 82 is deformed to facilitate the insertion of the edge of the dust paper or clothes. Thereafter, the strip hole 82 returns to its deformation to fix the dust paper or clothes, making it easy to use and install.

[0033] In a preferred case, a partition 53 is provided in the liquid storage tank 5 to divide it into a liquid adding chamber 51 and a sterilization chamber 52.

When the mop rod 1 is parallel to the mop board 2, the positioning protrusion 16 is elastically clamped in the positioning slot 15 to prevent the mop board 2 from changing direction during the scraping and dehydration process.

[0036] In a preferred case, the bottom plate 4 is fixedly connected to the lower side of the cover plate 3, and the connection method can be any one or any combination of screw connection, clip connection or plug connection. A fixed hanging tooth 42 is provided at one end of the base plate 4 and a movable hanging tooth 43 is provided at the other end, and a U-shaped bending structure 44 is provided between the movable hanging tooth 43 and the base plate 4; a clamping block 45 is provided above the movable hanging tooth 43, and a clamping position 46 is provided at the edge of the clamping block 45, and a notch 37 matching the shape of the clamping block 45 is provided on the cover plate 3, and a buckle 38 matching the clamping position 46 is provided on the edge of the notch 37; one end of the wiping object is fixed on the fixed hanging tooth 42, and then the U-shaped bending structure 43 is bent so that the movable hanging tooth 43 approaches one side of the fixed hanging tooth 42, so that it is convenient to fix the other end of the wiping object on the movable hanging tooth 43, and then the U-shaped bending structure 43 is restored to deformation, at this time the clamping block 45 moves to the notch 37, and the clamping block 45 is pressed so that the buckle 38 is clamped on the clamping position 46, and the movable hanging tooth 43 is fixed at the notch 37, which is convenient for installation and replacement of the wiping object.

[0037] In a preferred case, a scraping strip is provided along the length direction of the cover plate 3, and the scraping strip is fixedly connected to the cover plate 3. Furthermore, the long side of the cover plate 3 extends downward to form a wrapping edge 39, and the wrapping edge 39 wraps around both sides of the bottom plate 4, so that the mop board 2 as a whole is more beautiful and complete; the scraping strip is arranged on the wrapping edge 39, and the scraping strip can scrape excess moisture and dirt on the ground.

[0038] In the above technical solution, the transparent cover is opened, and after the bactericidal substance is added to the sterilization chamber, the transparent cover is closed to make the wipe on the mop board wet, and the floor can be cleaned. After the bactericidal substance is wet, the purpose of slow-release sterilization can be achieved. The use of the bactericidal substance can be observed from the transparent cover, which is convenient for timely addition. If the floor needs to be deeply cleaned, the cleaning liquid is directly added to the liquid adding chamber from the hollow part, and the cleaning liquid infiltrates into the wipe from the seepage port, thereby deeply cleaning the floor. When using dust paper or waste clothes to wipe the floor, the dust paper or waste clothes is wrapped around the mop board, and its edge is inserted into the hollow part. At this time, the strip hole will be deformed and the edge of the dust paper or waste clothes will be clamped and fixed, so that the secondary use of waste clothes can be realized very conveniently.

[0039] This embodiment is only an illustration of the concept and implementation of the utility model, and does not limit it. Under the concept of the utility model, technical solutions that have not been substantially changed are still within the scope of protection.
