Fig. 2 is prior art (patent No. 03226777.0) structural representation; Among the figure, pull switch 15 is made up of stay wire 25, extension spring 16, pulley 24.

Detailed ways:

The utility model is further described as follows with reference to the accompanying drawings in conjunction with specific embodiments:

As shown in Figure 1, the utility model includes a water tank 4, the upper part of the water tank 4 is provided with a float valve 3, which is connected with the float 1, and the connection is provided with an adjusting screw 2, and the float 1 can be adjusted in the water tank 4. This height determines the upper limit water level A of sufficient cleaning water in the water tank 4. The upper limit water level A defined by the float 1 is close to and lower than the position B on the bottom surface of the top of the siphon 10. The float valve 3 is provided with a water outlet 6, and the float The ball valve 3 is connected with the water inlet pipe 5, and water can flow into the water tank 4 from the water outlet 6 through the water inlet pipe 5. A siphon valve 8 is installed at the bottom of the water tank 4 to connect with the siphon pipe 10. The siphon valve 8 includes a corrugated membrane 9 and a water inlet hole. 7. The water outlet at the bottom of the siphon valve 8 is connected to the flushing pipe 12 through the conversion sleeve 11, and the other end is connected to the flushing pipe 12. The water tank 4 is also provided with a water injection pipe 19, one end of the water injection pipe 19 communicates with the water inlet pipe 5 through the starting device 23, water can flow into the water tank 4 and the water injection pipe 19 respectively through the water inlet pipe 5, and the other end of the water injection pipe 19 is connected to the water tank 4 inside the exposure.

As shown in the figure, the starting device 23 of the utility model can introduce the water in the water inlet pipe 5 into the opening device of the water injection pipe 19. It is composed of a pressure-opening valve 13 with a delay function and a solenoid valve 14 with a delay function. It can also be used alone to communicate with each other between the water inlet pipe 5 and the water injection pipe 19 . When pressing the push-open valve 13, the water in the water inlet pipe 5 can enter the water injection pipe 19 with a delay of 10 seconds-150 seconds. The solenoid valve 14 can be opened by the power supply 22, controlled by a button or controlled by an infrared probe. When using infrared probe control, when someone passes by within the effective detection distance, a signal can be sent, the power is turned on, the solenoid valve 14 is driven to connect the water injection pipe 19, the power is cut off when the person leaves, the solenoid valve 14 is powered off, and the water injection pipe 19 Stop the water.

The working process of the utility model: when the water in the water tank 4 is short of water or the water level is lower than the upper limit water level A, the pressure water enters the valve body of the float valve 3 through the water inlet pipe 5, flows into the water tank 4 from the water outlet 6, and when the water level in the tank rises to the upper limit When the water level is A, the floating ball 1 floats up with the rise of the water level, its lever rotates around the junction point, and the end point of the force arm moves downward, pushing its valve core to close the water inlet pipe 5, and the water tank 4 stops water intake; the siphon valve 8 enters the water tank 4 During the process, water enters the siphon valve 8 from the water inlet 7, so that the corrugated membrane 9 and the upper part of the valve body form a cavity. Higher than the upper limit water level A in the tank. The siphon effect cannot be formed, and the water tank 4 maintains the water storage state; when the external force pushes the valve 13 to open or activates the solenoid valve 14 through the power supply 22, the water inlet pipe 5 communicates with the water injection pipe 19, and the water in the water inlet pipe 5 quickly enters the water tank through the water injection pipe 19 4, within a short period of time (10 seconds to 150 seconds), the water surface in the water tank 4 exceeds the top and bottom surface B of the siphon tube 10, and the water enters the valve body of the siphon valve 8 through the water inlet 7, and then enters the siphon tube 10. Next, the siphon tube 10 simultaneously draws the water in the cavity of the siphon valve 8 into the siphon tube 10, flows into the urinal through the flushing tube 12, and forms a continuous siphon effect. Cross-section, the water in the cavity "does not make ends meet", negative pressure occurs, the corrugated membrane 9 is sucked upward, the flushing pipe 12 is turned from closed to open, and the water in the water tank 4 flows into the urinal from the flushing pipe 12 for flushing; when the water tank 4 When the water level drops to the lower limit, the water in the cavity of the siphon valve 8 is evacuated, the siphon effect stops, and the corrugated membrane 9 resets downward to close the nozzle of the flushing pipe 12. At this time, the float 1 loses buoyancy and has already drooped, and the pressure water pushes the float valve open 3. The spool injects water into the water tank 4 until the water level reaches the upper limit water level A. When someone goes to the toilet, the starter 23 is opened to flush the urinal; The difference is that the lower end of the water injection pipe 19 of the present utility model is not communicated with the siphon pipe 10 of the siphon valve 8 . Therefore, when the water level in the water tank rises from the low water level to the upper limit water level A, even if the starting device 23 is turned on, the water level in the water tank 4 cannot reach the top of the siphon tube 10 due to short-term (less than 10 seconds-150 seconds) water injection. Bottom surface position B, thus siphon tube 10 can not form siphon action, thereby can not open siphon valve and make flushing tube 12 discharge water and clean, like this just can save water. In addition, the utility model ensures that there is enough water for effective cleaning every time, and at the same time, the number of actions of the corrugated film 9 of the siphon valve 8 is reduced, and its wear is reduced, thereby prolonging the service life of the siphon valve 8 .
