Pneumatic control water inlet valve for closestool and short water tank closestool
The pneumatic control water inlet valve comprises a brush ring water inlet valve, an air bag communicated with an external air inflation structure through an air inflation hole is arranged in the brush ring water inlet valve, and an air leakage hole is formed in the air bag. The brush ring water inlet valve is further provided with an air leakage control structure which is controlled by the height change of the liquid level in the closestool water tank and can act on the air leakage hole. By means of the additionally-arranged air leakage control structure, the air bag of the brush ring water inlet valve can be automatically controlled to conduct air leakage according to the change of the height of the liquid level in the closestool water tank when the closestool flushes water, so that the brush ring water inlet valve is closed, the problem that the requirement for the inflation amount is high due to the fact that small holes are used for exhausting air is effectively solved, and production and use cost can be reduced.
本发明公开一种马桶用气控进水阀及矮水箱马桶，包括刷圈进水阀，刷圈进水阀内部设置有通过充气孔与外部充气结构相连通的气囊，气囊上开设有一泄气孔，刷圈进水阀上还设置有受马桶水箱内液位高度变化控制并能作用于泄气孔的泄气控制结构。本发明通过增设的泄气控制结构可由马桶冲水时其马桶水箱内液位高度的变化来自动地控制刷圈进水阀的气囊进行泄气从而关闭刷圈进水阀，有效避免了使用小孔排气导致对充气量要求较多的问题，有利于降低生产和使用成本。
