Anti-freezing flushing device and energy-saving, sanitary and environment-friendly toilet thereof

Abstract

The invention discloses an anti-freezing flushing device and an energy-saving, sanitary and environment-friendly toilet thereof. The anti-freezing flushing device is connected with a water supply system. The flushing device comprises a control switch, a water outlet pipeline and a water drainage pump; the water drainage pump is electrically connected with the control switch; the water supply system is arranged in an underground anti-freezing soil layer; the water drainage pump is connected with the water supply system and the water outlet pipeline; the water outlet pipeline penetrates througha ground frozen soil layer, and a water outlet of the water outlet pipeline extends out of the ground surface; when the water drainage pump is started through the control switch, water in the water supply system is pumped into the water outlet pipeline to form flushing water to be discharged; and when the water drainage pump is stopped, retained water in the portions, located on the frozen soil layer and the areas above, in the water outlet pipeline flows back into the water supply system. According to the anti-freezing flushing device and the energy-saving, sanitary and environment-friendly toilet, by controlling the flowback type water drainage pump, the retained water in the water outlet pipeline and the areas above can be rapidly and completely discharged, the retained water is made toflow back into the water supply system, water sources are saved, the problem that the water discharge pipeline freezes and the pipeline is fractured is avoided, and the problem that due to freezing,country dry latrine pits are dirty, disorderly and bad is solved.

Description

technical field [0001] The invention relates to the technical field of water supply, in particular to an antifreeze flushing device and an energy-saving, hygienic and environment-friendly toilet, which is suitable for rural or outdoor users in low-temperature cold northern regions. Background technique [0002] At present, dry toilets in rural areas generally cannot be flushed, attract flies in summer, freeze and cannot be cleaned in winter, and the sanitation conditions are very poor. With the popularization of tap water, tap water pipes have become an indispensable part. In rural areas, tap water pipes and faucets are generally installed in the yard. The outdoor temperature in winter is often below zero, especially in northern areas, where the temperature at night can be as low as minus ten degrees. For example, in the northeast of China, the outdoor temperature is the coldest in winter. The temperature even drops below minus 30 degrees, and the water in the water pipes of...
