Description

Cleaning head and cleaning tool

Technical Field

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

Background

With the development of modern technology, floor cleaning tools have been diversified, including brooms, mops, floor wipers, dust collectors, and the like. The cleaner is a very conventional floor cleaning tool, but the cleaner is very noisy and uncomfortable. And the garbage is cleaned only by sucking the garbage into the garbage box.

Brooms, mops and floor wipers belong to the class of mopping cleaning tools and 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, these existing mopping and sweeping all-in-one machines either need to be washed continuously, or have complex structures and high manufacturing cost, so that ordinary consumers are prohibited. Furthermore, existing floor cleaning tools can only clean dry waste (brooms, cleaners, etc.) or can only be used to clean liquid waste (mops, floor mops, etc.). It is said to be unwarranted by the hand that the cleaning of dry and wet mixed waste, in particular sticky waste (such as syrup, ketchup, etc.), is either particularly poor or very laborious (e.g. with rags, requiring multiple washes).
