Fig. 4 is according to the closet automatic flushing device that the utility model proposes, the working state figure when the people leaves the automatic flushing in back closet;

Fig. 5 is the sectional view along 1-1 line among Fig. 1.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

This device comprises a foot rest 2, and there be the size shape breach similar to the neighboring of closet 1 in its central authorities, and this breach matches with the closet neighboring, as shown in Figure 5.The front end of pedal 2 has two fulcrums 3 to be supported on the ground 4, the rear portion of pedal and link rod 5 are hinged, this link rod 5 extends upward, its middle part connects with a normally closed type stop valve 6, one end and the outlet pipe 16 of stop valve 6 link, the other end and feed pipe 18 link, the other end of link rod 5 is articulated on the drive link 7, one end and another link rod 11 of drive link 7 are hinged, this link rod extends down in the water tank 14 that is fixed on the installed surface 10 from pin joint, its end connects with a stop valve 15 open in usual that is installed in water tank 14 lower drain port places, and stop valve 15 links with cleaning hose 17, and this pipe 17 extends downward closet 1 water filling portion.One water inlet is arranged at the top of water tank 14, at water inlet one meter valve 12 is housed, meter valve 12 is provided with one and is used to control the ball float 13 that valve port opens and closes, the other end of drive link 7 is by being fixed on the moving fulcrum 8 on the installed surface 10 and being upturned, its end and a back-moving spring 9 link, the other end of this spring 9 is fixed on the installed surface 10, as shown in Figure 1.

When human body 19 steps down on the pedal 2, because health gravity acts on downwards, pedal 2 is downward-sloping, the link rod 5 that drive is articulated in the pedal rear portion together moves down, the normally closed type stop valve 6 that connects with link rod 5 middle parts is opened, water passes through feed pipe 18 through stop valve 6, water pipe 16 enters water tank 14 by meter valve 12, link rod 5 move down open normally closed type stop valve 6 in, beginning under the effect of bar 5 around being fixed on moving fulcrum 8 on the installed surface 10 with the hinged drive link 7 of link rod 5 other ends to lower swing, thereby driving the link rod 11 that is hinged with its end moves down, the stop valve open in usual 15 that connects with link rod 11 other ends is closed, and at this moment water tank begins retaining.Drive link 7 springs 9 joining ends stretch spring 9, as shown in Figure 2 around upwards swing of fulcrum 8.

In case meter valve 12 is then opened in beginning water filling in water tank under the effect of water, meter valve 12 is provided with one and is used to control the ball float 13 that valve port opens and closes, and when the water in the water tank reached predetermined water level, meter valve 12 was closed, and stopped to continue water filling in water tank, as shown in Figure 3.This meter valve can adopt float valve.

After human body leaves pedal 2, under the effect of back-moving spring 9, drive link 7 and link rod 5,11 hinged ends are upwards put around moving fulcrum 8, drive the link rod 5 and 11 that is hinged with it and move up together, and then stop valve 6 is closed, stop valve 15 is opened, water in the water tank 14 enters cleaning hose 17 by stop valve 15, begins closet 1 is washed, as shown in Figure 4.After the current in the water tank 14 were most, whole device returned to off working state as shown in Figure 1.

Its closet 1 that matches with breach on the pedal 2 of the closet automatic flushing device that the utility model provides can be a squatting pan, also can be western type toilet.
