目前,用于冲洗蹲便器的装置,主要有通截止阀和高位水箱。这两种装置都是手动的很多人为了个人卫生不愿用手去接触阀的手柄,或水箱的拉绳。这严重影响了公共卫生。本装置的特点是在蹲便器的脚踏位置安有一个受踏板控制的,能够自动延时关闭的阀(如附图所示)。当使用厕所时,人站在踏板上,踏板在人的重量的压迫下向下运动,压动阀上的控制阀芯。这样,阀就自动开启了。但是阀并不立刻放水(此功能由阀的内部结构所致,这里不作详述),而是等到人离开厕所后自动放水冲洗,并自动延时关闭。如附图所示,踏板的上表 At present, the devices used for flushing the squat toilet mainly include a stop valve and a high water tank. Both of these devices are hand-operated by many people who do not wish to touch the handle of the valve by hand, or the pull string of the water tank, for personal hygiene. This has seriously affected public health. The feature of this device is that there is a pedal controlled by the pedal in the foot position of the squatting pan, and the valve can be automatically delayed and closed (as shown in the drawing). When using the toilet, the person stands on the pedal and the pedal moves downwards under the pressure of the person’s weight and presses the control spool on the valve. In this way, the valve opens automatically. However, the valve does not immediately discharge water (this function is caused by the internal structure of the valve, and will not be described in detail here), but it will wait until the person leaves the toilet automatically drain water and automatically delay the closure. As shown in the figure, the top of the pedal
