Description

Excrement collecting and discharging device and waterless closestool
Technical Field
The invention belongs to the technical field of sanitary wares, and particularly relates to a defecation collecting device and a waterless closestool.
Background
The flush toilet is common sanitary ware in modern life, and compared with a squatting side toilet, the flush toilet brings great convenience to daily life of people. However, the conventional toilet needs to be flushed with flushing water after using the toilet, and excrement in the toilet is transferred from the toilet to a drainage pipeline so as to ensure the cleanness of the toilet. Therefore, the use of the toilet bowl is often supported by a perfect building pipeline network system and is limited by factors such as pipeline laying and pipeline maintenance, the number and the positions of the toilet bowl are limited, the toilet bowl is popularized only in a region with relatively developed economy, and the use of the toilet bowl is still a very luxury in regions with general economic conditions, backward building pipeline network system construction technology or severely deficient water resources.
In recent years, waterless flushing-free toilets which do not need to be flushed by water appear in the market, the problem of dependence of flushing toilets on water supply and drainage is effectively solved by the appearance and application of the waterless toilets, and the arrangement and popularization of the toilets in water resource-poor areas are made possible. However, since the toilet is not flushed by water, how to quickly and effectively discharge excrement in the toilet becomes a key problem to be solved by the deep development of the waterless toilet technology, and the existing waterless toilet often has the problems of difficult defecation or untimely defecation and the like, so that the use experience of a user is seriously influenced.
