Specifically, the flushing flow of the utility model is as follows:

1. Normal flushing

(1) The first electromagnetic valve 81 acts, and the washing ring spray head 6 discharges water to wash the pan surface of the urinal 11;

(2) After the water outlet t1 period of the washing ring spray head 6, the water pump 3 is started, the water outlet of the first flow channel 71 of the spray head 7 is sprayed to flush dirt into the sewage pipeline 12 and form siphonage quickly, the water level of the water sealing surface drops quickly, and as the washing ring spray head 6 is still discharging water, the dirt on the pan surface can be flushed to a position which is easy to be flushed away by the water flow at the bottom of the water storage bend, and can not be swirled to the upper part of the pan surface or be detained on the pan surface. As the dirt is quickly gathered to the small area of the trap, the visual effect is greatly improved, and the user experience is improved.

(3) After the first flow channel 71 of the spray nozzle 7 is discharged for a period of time t2, the first electromagnetic valve 81 is reset, the ring washing spray nozzle 6 stops discharging water, then the second electromagnetic valve 82 acts, the second flow channel 72 of the spray nozzle 7 is discharged for strengthening the spray, two spray water flows are simultaneously flushed to generate strong impact force, and when heavy objects which are easy to block are flushed, the heavy objects can be forcibly filled into the sewage pipeline 12, so that the toilet is thoroughly blocked.

(4) After the second flow passage 72 of the spray head 7 is flushed for a period of t3, the water pump 3 stops operating, and the first flow passage 71 of the spray head 7 stops discharging water. The second flow passage 72 of the spray nozzle 7 continuously sprays, and as the water outlet of the second flow passage 72 is close to the bottom of the trap, dirt close to the bottom of the trap can be washed, so that the second flow passage 72 is kept continuously sprays, and dirt can be thoroughly washed. On the other hand, the water in the trap is basically pumped out, the spray nozzle 7 is exposed to the air, and a large noise is generated, at this time, the water pump 3 stops working, and only the second flow channel 72 of the spray nozzle 7 is left for spraying, so that the flushing noise is reduced.

(5) After the water pump 3 stops operating for a period of time t4, the second electromagnetic valve 82 is reset, and the second flow passage 72 of the spray nozzle 7 stops discharging water. Immediately after the first electromagnetic valve 81 is operated, the water from the washing ring spray head 6 is supplied to the water storage bend.

(6) After the water outlet t5 period of the ring-washing spray head 6, the first electromagnetic valve 81 is reset, and the water outlet of the ring-washing spray head 6 is stopped.

The optimal value interval of the t1 time period is 0.5s-2s. The water flow from the washing water to the first wave water generally passes through 0.5s for flushing dirt to the water sealing surface, so that the water pump 3 can be started after 0.5s of the washing water. The water pump 3 is not started too late, otherwise, the dirt rotates on the water surface to affect the user experience, and the dirt can be swirled to a high place after the water level rises.

The optimal value interval of the t3 time period is 1s-2s. The resultant flushing of the first and second flow paths 71, 72 is primarily to prevent the tubing from being blocked by a weight which is characterized by either not flushing out of the blockage or flushing down, so that the flushing time is not necessarily long. In this way, the duration of the noise generated by the combined force flushing of the first and second flow paths 71, 72 is short.

2. Power cut flushing

(1) The first electromagnetic valve 81 acts, and the washing ring spray head 6 discharges water to wash the pan surface;

(2) After a period of flushing, the first electromagnetic valve 81 is reset, and the water outlet of the washing ring spray head 6 is stopped; immediately after the second electromagnetic valve 82 acts, the second flow passage 72 of the spray nozzle 7 is sprayed with water to flush dirt into the sewage pipe 12, and the water outlet of the second flow passage 72 is close to the bottom of the trap, so that the dirt close to the bottom of the trap can be thoroughly flushed;

(3) After the second flow passage 72 of the spray head 7 is flushed for a while, the second solenoid valve 82 is reset, and the second flow passage 72 of the spray head 7 stops water discharge. Immediately after the first electromagnetic valve 81 is operated, the water from the washing ring spray head 6 is supplied to the water storage bend.

(4) After a period of water replenishment, the first solenoid valve 81 is reset, and the washer nozzle 6 stops water discharge.

According to the utility model, when the washing ring is washed, the washing of the first flow passage 71 of the spray nozzle 7 is started, on one hand, the washing ring and the spraying are carried out simultaneously, so that dirt cannot be detained on the pan surface; on the other hand, the water supply of the washing ring is tap water, the water supply of the first flow of the spray nozzle 7 is a water pump 3, the water sources of the two water supplies are different, and the water pressure is not weakened mutually. In the utility model, in the later period of flushing, the flushing of the first flow passage 71 of the spray nozzle 7 is closed in advance, and the continuous spraying of the second water passage of the spray nozzle 7 is reserved, on one hand, the continuous spraying of the first flow passage 71 of the spray nozzle 7 is beneficial to thoroughly flushing the dirt at the bottom, and on the other hand, the spraying of the second flow passage 72 of the spray nozzle 7 is only reserved, so that the flushing noise of the water pump 3 is beneficial to reducing. In the whole flushing process, the flushing is enhanced only when the flushing is most needed by virtue of the extremely short flushing time of the water pump 3, so that the flushing effect is ensured, the water consumption of the flushing of the water pump 3 is ensured to be small, the volume of the water tank 2 can be very small, the occupied space is reduced, and the cost is reduced.

Through the improvement, the utility model can be flushed after power failure, and the realization cost is low; in addition to the flushing of the water pump 3, tap water is used for enhancing the injection during the injection, so that the power of the water pump 3 is not very high, the requirement on the circuit power is reduced, and the overall cost is further reduced; the water pump 3, the flushing valve 8 and the water inlet valve 20 are all universal mature components, the work is reliable and stable, and the batch purchasing cost is low.
