Description

A water-saving toilet

technical field

The utility model belongs to the technical field of sanitary ware, and relates to a water-saving toilet, in particular to a water-saving toilet that can be flushed without water by separating feces and urine.

Background technique

Environmentally friendly toilets have developed to a certain extent in my country. The most widely used public toilets are air-pressure water-saving flushing toilets and foam-covered toilets. The air-pressure water-saving toilet flushing system adopts the principle of booster pump, which pushes a small amount of water into the toilet bowl with great pressure, which has the same cleaning effect as the water flushing toilet, and can save 60% of the water compared with the water flushing toilet. , used in many areas with abundant water resources. The foam-covered toilet system adopts the method of foam covering to cover the feces, and under the action of the foam, the feces slide into the sewer pipe. The foam-covered toilet completely solves the problem of wasting water resources and requires only a small amount of water. That is, without expanding the source of pollution, it is widely used in many rural areas in Beijing where water is scarce and there is no sewage pipe network.
