Description

Cleaning tool

Technical Field

The disclosure belongs to the technical field of cleaning equipment, and particularly relates to a cleaning tool.

Background

With the development of modern technology, cleaning tools are diversified, including brooms, mops, floor wipers, dust collectors, and the like. The dust collector is a non-conventional cleaning tool, but the noise of the dust collector is very loud and uncomfortable, and the dust collector only sucks the dust into the dust box to clean the dust.

Brooms, mops and floor wipers are cleaning tools of the mop type, which generally have a fixed cleaning part, the cleaning capacity of which is determined by the dirt removing and absorbing capacity of the cleaning part. Since the cleaning portion is contaminated as soon as it comes into contact with the soiled floor, the cleaning power is gradually reduced during the subsequent cleaning process, and complete cleaning cannot be achieved, particularly when a large area is continuously swept. Therefore, the cleaning articles must be washed frequently, which is very troublesome.

For Chinese consumers, sweeping and mopping are necessary when cleaning the floor, and the floor cannot be thoroughly cleaned only by sweeping or mopping. However, the existing mopping and sweeping all-in-one machine needs to be washed continuously, or the structure is complex, the manufacturing cost is high, and common consumers are prohibited.

Moreover, existing cleaning tools can only clean dry waste (brooms, cleaners, etc.) or liquid waste (mops, etc.). It is said to be unwarranted by the hand in terms of cleaning either particularly poor or laborious (e.g., multiple washes with rags) of dry and wet mixed waste, particularly sticky waste (e.g., syrup, ketchup, etc.).

In addition, the mopping machine or the mopping and sweeping all-in-one machine can be provided with a water tank for storing water. The existing water tanks are generally of a simple box-like structure and are fixedly mounted on the machine, and water squeezed out of the drum may overflow to the ground and be inconvenient to clean. Viscosity
