Hard surface vacuum cleaner and cleaning method thereof

Abstract

The invention discloses a hard surface vacuum cleaner and a cleaning method thereof. The hard surface vacuum cleaner comprises a casing, a negative pressure source and a main water tank, wherein a nozzle on the casing and a suction pipe communicated with the nozzle are matched to form a water-gas mixed suction channel, and the water-gas mixed suction channel is connected with a centrifugal fan impeller to form a water-gas vortex separation structure; a water-gas mixture vortex deceleration cabin, a temporary solid dirt storage chamber and a temporary liquid dirt storage chamber which are communicated are further formed in accommodating space of the casing; the water-gas mixture vortex deceleration cabin and the temporary solid dirt storage chamber are formed between the negative pressure source and the nozzle, so that a sewage and dirt storage and separation channel is formed; and the temporary liquid dirt storage chamber is provided with an exhaust device communicated with the outside, and a gas separation channel is further formed, so that vacuum cleaning of a hard surface is realized. A structure required for water-gas separation is simple, and the water-gas separation effect is good.

Description

technical field [0001] The invention relates to a water absorbing device, in particular to a hard surface vacuum cleaner and a cleaning method thereof. Background technique [0002] The hard surface vacuum cleaners currently on the market use a water-air separation method to keep the dirty water in the tank while the air is exhausted through the exhaust pipe. However, when there is a lot of water in the water tank, or the angle of use by consumers is too large and too intense, the sewage is very easy to enter the negative pressure source through the exhaust pipe and the air to be sprayed out. Not only is it easy to damage the negative pressure source, but the dirty water sprayed will also Dirty user's clothes and environment cause secondary pollution. [0003] At the same time, when consumers clean the sewage, if there are large objects such as hair and sand in the sewage, it will cause problems such as blockage of the suction pipe and blockage of the water inlet of the wa...

Problems solved by technology

However, when there is a lot of water in the water tank, or the angle of use by consumers is too large and too intense, the sewage is very easy to enter the negative pressure source through the exhaust pipe and the air to be sprayed out. Not only is it easy to damage the negative pressure source, but the dirty water sprayed will also Dirty user's clothes and environment cause secondary pollution

[0003] At the same time, when consumers clean the sewage, if there are large objects such as hair and sand in the sewage, it will cause problems such as blockage of the suction pipe and blockage of the water inlet of the water tank, resulting in excessive load of the negative pressure source and burning. risk

In addition, the inner cavity of glass vacuum cleaners currently on the market is not easy to clean, and it is very easy to form a breeding ground for bacteria, which endangers the health of consumers at home.
