Description

Mop bucket

Technical Field

The invention relates to the technical field of daily necessities, in particular to a mop bucket.

Background

The mop is a long-handle cleaning tool for scrubbing the ground, also called a mop rag, and also widely called a long-handle cleaning tool, the mop is derived from the rag, the most traditional mop is formed by bundling a bundle of cloth strips at one end of a long wood rod, the mop is simple and cheap, and the working head is changed into the bundle of cloth strips from a rag block, so that the mop has strong dirt-removing capability. After long-term use, new problems come, the mop head, which is a working part of the mop, needs to be continuously cleaned, and the damage of the cleaning of the mop head to the hands of an operator is increased, so that the problem to be solved is solved. Along with the continuous growth of scientific trees, materials used by the mop head are gradually extensive, non-woven fabrics, superfine fibers and the like are developed from early cotton cloth strips, even a piece of collodion (collodion mop) is directly used, and the collodion mop is more suitable for clearing accumulated water on the ground such as a kitchen, a toilet and the like due to the strong hydroscopicity of the collodion and the matching of a convenient water squeezing device. The crank mop moves the head ribs on the mop rod, the crank component is additionally arranged on the traditional straight rod, so that the mop head can freely rotate on the ground, labor is saved, the problem that the straight rod mop is stood down to be labored and garbage scraps are pushed away to be stored under the mop head is solved, and meanwhile, the crank can provide power for the high-speed rotation and thorough cleaning of the mop.

So far, the functions of the mop are continuously expanded, and the auxiliary tools are diversified, which presents a situation of hundreds of flowers. The existing improvement is mainly carried out on a mop head and a mop rod, or a special barrel is provided to be matched with the mop head to realize the function of automatic spin-drying or wringing. At present, most mops are cleaned without matched mop barrels, and only the mops are cleaned in a common water container, so that when the mops are mopped and cleaned, water in the container is more and more dirty, floating objects such as hair and debris exist, the mops are difficult to clean again, the mops can be kept clean only by frequently changing water, water resources can be seriously wasted, and waste is caused.
