Squatting pan and squatting pan flushing system

Abstract

The invention discloses a squatting pan which comprises a squatting pan ceramic body, a urinal is arranged at the top of the squatting pan ceramic body, a water sinking bay is arranged at the bottom of the urinal, and the water sinking bay is connected with a blowdown siphon. An annular flushing pipeline is arranged at the top of the urinal, and a flushing hole set is formed in the wall face of the annular flushing pipeline. A water storage space used for preventing external air from entering the water tank drainage pipe from the annular flushing pipeline is formed in the squatting pan ceramicbody, and the bottom of the water storage space is lower than the annular flushing pipeline. The upper portion of the water storage space is communicated with the annular flushing pipeline, and a water inlet used for being connected with a drainage pipe is formed in the side wall of the water storage space. The invention further discloses a squatting pan flushing system comprising the squatting pan. External air is prevented from entering the water tank drainage pipe from the annular flushing pipeline through the water storage space, noise generated when the water tank works is greatly reduced, water capable of directly acting on next flushing can be pre-stored in the water tank drainage pipe after each time of flushing, the stroke of water is saved, and the flushing effect is good.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to a squatting pan and a squatting pan flushing system. Background technique [0002] Existing squatting toilet flushing systems such as figure 1 As shown, in the normal water-stop state, the outside air communicates with the outlet 1002 of the drain valve base through the overflow pipe 1001 , and the outside air communicates with the outlet 1004 of the drain pipe through the ceramic water channel 1003 . When the drain valve is opened, 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 draining, a negative pressure will be generated in the drain channel 1005, and the external Under the action of atmospheric pressure, air will be mixed into the drain port 1002 of the valve base together, so that the drain channel 1005 cannot store water, thereby...
