Description

Floor brush module for cleaning machine and cleaning machine

Technical Field

The utility model relates to the field of mobile cleaning equipment, in particular to a floor brush module for a cleaning machine and the cleaning machine.

Background

In order to facilitate cleaning of the floor, the conventional mobile cleaning device mostly adopts a rolling brush as a sweeping executing member, and brush hairs on the periphery of the rolling brush are contacted with the surface to be cleaned through rolling of the rolling brush, so that dirt attached to the surface to be cleaned is cleaned. The rolling brush structure covers a relatively large cleaning area in cleaning, but the bristle-planting design form ensures that the rolling brush has insufficient scraping force on the surface to be cleaned and has limited cleaning effect.

Therefore, a part of products select to replace brush hair by the scraping blade, and the problem of insufficient scraping force is solved by scraping the scraping blade with relatively large force on the floor to be cleaned, but the novel problem is brought, namely, the rolling brush rotates at a high speed, and the scraping blade is driven to fly when the front particles of the brush hair of the rolling brush are bumped. Therefore, the chinese patent No. CN202223121664.2 discloses a cleaning device and a rolling brush assembly of the cleaning device, in which the dust collection chamber faces the working surface to be cleaned, and under the negative pressure of the cleaning device, fine dust such as dust and hair on the working surface is sucked into the rolling brush chamber along with the air flow through the gap between the front wall and the working surface, and large particle dust is sucked into the rolling brush chamber from the gap. Therefore, even if the gap between the front surrounding baffle and the working surface cannot reach the expected gap amount, the cleaning equipment can recover various garbage with different sizes, and the cleaning performance of the cleaning equipment is greatly improved.

Although the cleaning device realizes the guiding of the large-particle garbage by utilizing the notch at the front side, the cleaning device cannot be suitable for the common arrangement of different scraping blades, the pressure increase condition caused by fluid collection can occur in the rotating process of the special-shaped scraping blades in a partial area, the disordered movement of dust particles can be caused, and the guiding requirement of the large-particle garbage cannot be completely met.
