Description

A squatting pan and a squatting pan flushing system

technical field

The invention relates to the field of sanitary ware, in particular to a squatting toilet and a flushing system for the squatting toilet.

Background technique

The existing squatting toilet flushing system is shown in Figure 1. Under the normal water-stop state, the outside air is communicated with the drain valve base drain 1002 through the overflow pipe 1001, and the outside air is connected with the drain pipe water outlet through the ceramic body water pipe 1003. 1004 Connected. When the drain valve is opened, the water flows out through the drain port 1002 of the valve base. During normal use, since the drain port 1002 of the valve base communicates with the outside air through the overflow channel, when the drain is drained, a negative pressure will be generated in the drain channel 1005, and the outside will be exposed to negative pressure. Under the action of atmospheric pressure, the air will be mixed into the drain port 1002 of the valve base together, so that the drainage channel 1005 cannot store water, thereby reducing the drainage speed, and when flushing the squat toilet, the water in the drainage pipe 1005 will "squeeze the air" and make noise.
