Description

Middle-in front-discharge squatting pan

Technical Field

The utility model relates to a squatting pan, in particular to a middle-inlet front-discharge squatting pan.

Background

The squatting pan commonly used in the public washroom is provided with a flushing and discharging opening at the rear part of a pan groove. When people go to the toilet, the squatting pan moves forwards to avoid splashing sewage. Thus, the following problems are easy to occur when people go to the toilet: the front side flushing and discharging force is small, the falling slope is easy to flush and discharge unclean, dirt is hung or even residual excrement is accumulated, unnecessary toilet stool and air pollution can be caused, and a large amount of water is wasted by flushing and discharging the residual excrement again. In addition, when squatting before leaning on, urine is easy to splash out of the excrement tank, unnecessary pollution is caused, cleaning burden is additionally increased, and the cleanness and tidiness of the public toilet are further influenced.

The patent document CN202148590U discloses an optimized flushing structure and shape of a squatting pan, wherein all water outlets on the side surface of a middle-discharge squatting pan are plugged, and water outlets are reserved only at the front side and the rear side. The front water outlet and the rear water outlet are in fan shapes with optimized design, so that when fan-shaped flushing water flow is formed, the problems that side splashing urine cannot be flushed in place and peculiar smell of residual urine is caused still easily occur. When the middle-discharge squatting pan adopts the traditional design that the front side and the rear side are flushed with water, although the periphery can be flushed in place, the peculiar smell of residual urine is avoided; however, when the air-water mixed water-saving flushing and draining mode commonly used in public toilets installed and constructed for many years is applied, the flushing force of flushing water flow for pressing down the flushing toilet at the middle lower drainage port is remarkably reduced by the flushing slope arranged at the rear part of the toilet groove in an extending mode, and the problem that residual toilet is still retained by water sealing at the middle lower drainage port after flushing and draining is very likely to occur. In addition, the excrement falling slope arranged on the rear part of the excrement tank in an extending mode weakens the air-water mixed flushing force on the rear part of the excrement tank, and in order to guarantee the air-water mixed flushing force, the flushing water quantity must be increased, and water is wasted.

Disclosure of Invention
