Description

Self-wringing foam cotton mop

Technical Field

The utility model relates to a cleaning tool, in particular to a self-squeezing foam cotton mop with a brand-new squeezing structure, wherein the foam cotton can be a collodion cotton head, a sponge head or the like.

Background

The water squeezing modes of the foam cotton mop in the current market are roughly three types: the first one is hand-pulling water squeezing type, such as a Chinese utility model patent 'collodion mop' with patent number ZL03231227.X (publication number CN 2626415Y), a Chinese utility model patent 'plug-in water squeezing collodion mop' with patent number ZL 200920121093.8 (publication number CN201409887Y), a Chinese utility model patent 'a collodion mop' with patent number ZL 200920075021.4 (publication number CN201453183U), and a Chinese invention patent 'movable multifunctional collodion mop' with patent number ZL201110102067.2 (publication number CN102138771A), which all disclose such collodion mops; the second type is a mop head overturning integral water squeezing type, for example, a series of patents applied by the applicant, the mop head overturning integral water squeezing type comprises a mop rod and foamed cotton, wherein the foamed cotton is movably connected to the lower end of the mop rod, the mop rod is provided with a squeezing device capable of sliding up and down relative to the mop rod, the foamed cotton can be rotated to the length direction of the foamed cotton to be basically parallel to the mop rod and aligned to the water squeezing device, when water is squeezed, the water squeezing device slides up and down along the length direction of the foamed cotton and squeezes the bottom surface of the foamed cotton to realize water squeezing, and when the mop head is used for mopping, the foamed cotton is completely separated from the water squeezing device; the third is a double-fold water squeezing type.

Each water squeezing mode has disadvantages, the first water squeezing structure has long whole transverse length of the water squeezing part, is heavy, has large contact area between the water squeezing rod and the collodion cotton head in the water squeezing process, greatly increases the friction force during water squeezing, and has multiple rows of water squeezing rods on the front side or the rear side, more material consumption and higher squeezing frame cost; due to the particularity of the structure of the squeezing frame, the collodion head and the mop rod are fixedly connected, and the collodion head cannot be completely separated from the squeezing frame, namely the collodion head cannot rotate relative to the mop rod, so that the mop is inconvenient to drag when meeting specific occasions such as corners and has poor adaptability; the second water squeezing structure has the advantages that the foamed cotton is hard and is not easy to separate from the squeezing opening in the squeezing frame; the third type of wringing structure has a crease in the middle of the mop head, the mop head keeps an unfolded mopping state only by the elastic piece, but the unfolded straightness of the mop head has defects all the time, the folded mop head is always not too flat when mopping, so that part of the ground is not cleaned (such as the middle arched position), and the cleaning effect is not good enough.

In conclusion, the prior self-squeezing collodion cotton mop can be further improved.
