Background

At present, most rural toilets in China are traditional dry closets, and have the problems of large smell, more flies and mosquitoes, poor environmental sanitation and the like; even in cities with relatively good sanitary conditions, the excrement is treated in a simple septic tank and discharged to the environment. These unsanitary toilet environments are susceptible to the transmission of susceptible diseases.

Although the 'toilet revolution' is started comprehensively, the environment of the people in the toilet is greatly improved, most toilets still use water flushing as a main means, and a large amount of water resources are needed for flushing the toilets. China is a country with shortage of water resources per capita, and the water-flushing toilet places great pressure on water resources in China.

With the continuous pursuit of people for green and healthy life, the development of novel environment-friendly water-free toilets is imperative, and has great development space. The environment-friendly intelligent water-free toilet utilizes the biochemical degradation effect of microbial aerobic bacteria in degradation liquid auxiliary materials to perform in-situ resource, harmless and reduction treatment on human excrement and urine, water is not needed in the use process, and finally dry and clean biological fertilizer is produced.

However, when excrement, urine and the like are discharged to a toilet, the excrement, urine and the like can only contact with the surface degradation liquid and the auxiliary materials, so that the degradation speed is very low, the excrement, the degradation liquid and the auxiliary materials are ensured to be fully contacted by the stirring device, and the stirring device can be driven by the motor to realize the purpose.
