Compared with the prior art, the technical scheme of the patent has at least one or more of the following beneficial effects:

although the existing floor washing machine or floor mopping machine has various products, the main technical scheme is that a dust collector mechanism is added with a rolling brush structure, and various products of a company and a company of chasing are more typical. However, in the products of the technical route, a high-speed motor is needed to pursue the large suction force, because the sewage and dirt are sucked by utilizing the negative air pressure, the noise of the products is large due to the high-speed motor, and if the motor is muted, the cost is high; meanwhile, sewage and dirt are separated, related structures are arranged to prevent the sewage from entering the motor to cause damage, the product structure is complex, and further the cost is high; the design space of the product is limited, the water tank is often required to be arranged on the rod body, and even the sewage tank and the clean water tank are required to be arranged on the rod body, so that the gravity center of the product is unstable and easy to fall down; the complex structure makes the product itself heavier, which is unfavorable for the movement of the user.

More importantly, because the power consumption of the high-speed motor is larger, the cruising ability of the battery is a big problem, and products on the market can cruise for 60 minutes in a high-power working state very rarely, so that the number of battery packs is increased for improving the cruising ability, the cost is increased on one hand, and the weight of the products is further increased on the other hand.

The existing products also have a technical line product, such as a floor washing machine product of a water dripping company, which has no dust collector structure, wherein the product structure is a rolling brush and a scraping plate assembly, and sewage and dirt on the rolling brush are scraped into a sewage tank by using the scraping plate. The technical route omits the structure of negative air pressure of the dust collector, but has poor dirt removing effect because no negative pressure is formed; the scraping efficiency of the scraping plate is poor for dirt, and water on the rolling brush cannot be effectively removed, so that more water stains are left on the ground; if the scraping plate applies increased pressure to the rolling brush, the effect of squeezing the rolling brush to remove water can be improved, but the resistance between the parts is large, the parts are easy to damage, the rotation is easy to clamp, and the surface of the rolling brush of the fiber is pressed to be too flat, so that the rolling brush is not beneficial to adsorbing ground garbage. Meanwhile, the scraper is utilized to scrape the whole rolling brush surface, so that dirt and sewage flow into the sewage tank by utilizing the gravity principle, on one hand, the opening of the sewage tank is very large, otherwise, the sewage tank cannot be butted with the scraper, on the other hand, the capacity of the sewage tank is limited, and the position of the sewage outlet needs to be set lower, so that the sewage and the sewage can flow into the sewage tank by utilizing the principle.

This patent sewage lid subassembly mainly used closes the sewage case, and the sewage mouth of a river that its set up is adjustable to be opened and shut.
