Description

Floor brushes and scrubbers for scrubbers

technical field

The utility model relates to the technical field of smart home, in particular to a household washing machine.

Background technique

In the prior art, floor washing machines are generally divided into commercial floor washing machines and household floor washing machines. Commercial floor washing machines are generally used in large factories, garages, shopping malls, supermarkets, etc. Relatively small (generally less than 200 square meters) families.

For the household washing machine, its structure mainly includes the washing machine body and the floor brush. The washing machine body is provided with a water tank (to supply water to the drum) and a sewage tank (to collect sewage); it is also equipped with a controller, a spray liquid device, a drum motor for controlling the drum, a suction device and a host motor for controlling the suction device; and the floor brush is mainly provided with a drum and a guide channel for cleaning the ground. When working, the liquid spraying device is in an open state, and sprays liquid to the drum; the drum motor is in an open state, so that the drum rotates; the main engine motor is in an open state, and the liquid ( Sewage) is sucked from the diversion channel to the suction pipe, and finally flows into the sewage tank. This small household washing machine is widely favored by the public because of its convenience and practicality.

At present, according to user feedback, during the use of the washing machine, water stains will remain on the surface to be cleaned (such as the ground, wooden floor, etc.).

In view of the above problems, the bottom of the floor brush of the existing floor washing machine is provided with a rubber scraper, which is used to scrape sewage (and particulate impurities, etc.) into the guide channel. However, in practical application, it is found that there are the following two practical problems: (1) Only relying on the rubber scraper at the bottom of the floor brush cannot completely remove the water stains, and there are still residues; First, because the existing rubber scrapers are soft, As a result, there is a gap between the scraper and the surface to be cleaned, and the sewage cannot be scraped off well, resulting in residual sewage; second, when the floor brush is dragged backward, the rubber scraper at the bottom cannot be scraped; (2) due to the rubber The scraper is often turned over and then restored, resulting in a short service life. After a period of frequent use, the rubber scraper will partially break off or crack, leaving users with a bad experience.

Therefore, it is obviously of positive practical significance to develop a new floor brush to achieve better cleaning, avoid sewage residue, and improve user experience.
