In the present embodiment, the solenoid valve 2 includes a solenoid valve body 21, a seal assembly 22 provided on the solenoid valve body, and a solenoid valve plug 23.

The solenoid valve body 21 includes a valve body 211 and a bonnet 212. The valve cover 212 covers the valve body 211. The valve body 211 is provided with a water inlet passage 2111 communicated with the water inlet of the connector and a water outlet passage 2112 connected with the intelligent toilet.

The first drainage channel B1 is transversely arranged, one end of the first drainage channel B1 is connected with the water storage cavity 2113, and the second drainage channel B2 is vertically arranged and connected with the first drainage channel B1; the third drain passage B3 is transversely arranged, and has one end connected to the second drain passage B2 and the other end communicating with the outlet passage 2112 through the second inlet a 2.

The seal assembly 22 includes a first diaphragm 221, a second diaphragm 222, and a first spring 223. The second diaphragm 222 is fixed to the first diaphragm 221 and is disposed in the reservoir chamber 2113 together with the first diaphragm 221. The first spring 223 is disposed within the reservoir chamber 2113 and one end of the first spring 223 is secured to the reservoir chamber 2113 and the other end is fixedly connected to the second diaphragm 222. In order to prevent water leakage, a lining ring 224 is further disposed between the first spacer 221 and the water storage cavity 2113.

The first spacer 221 is provided with a first through hole and a second through hole (not shown). The second spacer 222 is provided with a first protrusion 2221 penetrating the first through hole and a second protrusion 2222 penetrating the second through hole. The end of the first projection 2221 is located within the inlet 2111, and the first projection 2221 is provided with an inlet conduit that communicates the inlet 2111 with the reservoir chamber 2113. The second projection 2222 is opposed to the first inlet a1 of the outlet passage 2112. The first spacer 221 is a plastic spacer; the second spacer 222 is a rubber spacer.

Further, the diameter of the water outlet F on the water storage cavity 2113 is larger than that of the water inlet conduit, so that when the electromagnetic valve 2 is opened, the amount of water discharged from the water storage cavity 2113 is much larger than that entering the water storage cavity 2113, so as to reduce the pressure of the water storage cavity 2113, and the water inlet passage 2111 is communicated with the water outlet passage 2112.

The upper end of the first spring 223 is provided with a leading-out portion 2231, the leading-out portion 2231 is inserted into the water inlet conduit, and the aperture of the leading-out portion 2231 is smaller than the aperture of the water inlet conduit, so that a gap is formed between the leading-out portion 2231 and the water inlet conduit, and water in the water inlet passage 2111 can flow into the water storage cavity 2113 along the gap.

The solenoid plug 23 includes a solenoid assembly 231, a second spring 232, a solenoid core 233, and a power cord 234. Solenoid coil assembly 231 is capped on valve cap 212. The power cord is connected to the solenoid coil, and the solenoid coil assembly 231 is connected to the outside through the power cord and energized. The solenoid core 233 is fixed in the solenoid coil assembly 231, and the lower end of the solenoid core 233 is located in the drain passage 2114. The second spring 232 is fixed to the upper end of the electromagnet core 233. For preventing the infiltration and leaking, strengthen sealing performance, as the utility model discloses a further optimization still is equipped with O type sealing washer 235 between electromagnetism core 233 and the valve gap 212.

When the solenoid coil assembly 231 of the solenoid valve 2 is not energized, the solenoid core 233 is only acted upon by the spring force of the second spring 232, and under the action of the second spring 232, the solenoid core 233 will move downward and block the drain passage 2114, thereby closing off the passage between the reservoir chamber 2113 and the outlet passage 2112. The first and

second spacers

221 and 222 of the sealing assembly are moved upward by the tensile force of the first spring 223. At this time, part of the water flows into the reservoir chamber 2113 from the water inlet conduit, and the first partition 221 and the second partition 222 are pressed downward to block the first water inlet a 1; the other part of the water impacts the side ends of the first and

second spacers

221 and 222 upward, and resists against the spring tension and the downward pressing force of the first spring 223 received by the first and

second spacers

221 and 222. Because the drainage channel 2114 is blocked, as the water in the reservoir chamber 2113 is continuously accumulated, the downward pressing force applied to the sealing assembly 22 is far greater than the spring tension and the impact force of the water applied to the sealing assembly, and the sealing assembly moves downwards slowly, so that the second convex part 2222 of the sealing assembly 22 is tightly attached to the first water inlet a1 of the water outlet channel 2112, and the first water inlet a1 is blocked, and the function of sealing the first water inlet a1 is achieved, and the water is prevented from flowing out.

When the solenoid coil assembly 231 of the solenoid valve 2 is energized, the solenoid core 233 is simultaneously acted upon by the spring force of the second spring 232 and the magnetic force of the solenoid coil assembly 231, and since the magnetic force exerted upon the solenoid core 233 is greater than the spring force, the solenoid core 233 moves upward to conduct the drain passage 2114. The water in the solenoid valve 2 flows along the water inlet passage 2111 to the reservoir chamber 2113, and at this time, part of the water flows into the reservoir chamber 2113 from the water inlet conduit, and the other part of the water strikes the side ends of the first diaphragm 221 and the second diaphragm 222, and resists against the spring tension and downward pressure of the first spring 223. Because the drainage channel 2114 is communicated, water in the water storage cavity 2113 flows out of the water outlet channel 2112 along the drainage channel 2114, and the water discharge amount is far larger than the water inlet amount, so that the water in the water storage cavity 2113 cannot be accumulated, the impact force of upward jacking and the spring tension applied to the sealing assembly 22 are far larger than the force of downward pushing in the water storage cavity 2113, the first partition 221 and the second partition 222 are jacked up, and the water inlet channel 2111 is communicated with the water outlet channel 2112; at this time, water in the inlet passage 2111 may flow out of the outlet passage 2112 along the first inlet a1, and the toilet bowl may be washed.

The sealing component seals the water outlet channel, the drainage channel is arranged on the outer side of the sealing component, water in the water storage cavity is drained, the sealing performance of the sealing component is guaranteed, normal drainage of the water storage cavity is guaranteed, the water leakage problem of the flushing device is prevented, and user experience is greatly improved. Furthermore, the electromagnetic valve is integrally arranged in the connecting piece, so that the stability of the flushing device is improved.

Example 2:

this embodiment is similar with embodiment 1, the difference lies in, in this embodiment, the connecting piece is the four-way pipe, the equal symmetry of left and right sides about the four-way pipe, wherein the four-way pipe is equipped with a water inlet 11 and three delivery port 12, the water receiving mouth and the running water pipeline intercommunication of lower extreme, delivery port 12 at left and right ends respectively installs an solenoid valve, wash by water through the solenoid valve control, wash intelligent toilet's just groove, additionally, in this embodiment, bottom symmetry at the vacuum breaker has set up 2 stopper 352, and the inner wall at the gas outlet is cyclic annularly provided with the lug 362 that the stopper 352 position corresponds, when the running water pipeline is at anhydrous state, the piston falls owing to the effect of its own gravity, stopper 352 and lug 362 contact, the limit whereabouts position of restriction piston, avoid piston shutoff gas outlet.
