One end of the water outlet pipe 21 is connected to the water inlet connecting pipe 42, and the other end is connected to the outlet of the electric angle valve 22. The electric angle valve 22 is used to be connected to the water supply device. By setting the electric angle valve 22, the water output of the water outlet pipe 21 can be controlled.

[0072] Furthermore, the signal line assembly 60 also includes an angle valve signal line 64 , one end of which is connected to the electric angle valve 22 , and the other end of which is connected to the power line 63 .

[0073] The flushing method of the flushing system according to the embodiment of the present invention is as follows:

[0074] Step S100: the probe assembly 30 receives the sensing information and transmits it to the brewing host 10 and the electric angle valve 22;

[0075] Step S200: The foam making host 10 receives the signal transmitted by the probe assembly 30, and the foam making host 10 makes foam, and thick foam is sprayed out from the foam outlet 4114;

[0076] Step S300: The electric angle valve 22 receives the signal transmitted by the probe assembly 30, waits for a first preset time, and then half-opens and remains half-open for a second preset time. A small amount of water flows through the outlet pipe 21 and is ejected from the outlet 4113.

[0077] Step S400 : the electric angle valve 22 is fully opened, a large amount of water flows through the water outlet pipe 21 and is sprayed out from the water outlet 4113 .

[0078] It should be noted that the first preset time may be the brewing time of the brewing host 10 , that is, the electric angle valve 22 is opened after the brewing machine 12 completes brewing.

[0079] It can be understood that when the distance between the outlet end of the bubble-making host 10 and the bubble outlet 4114 is smaller than the distance between the outlet end of the electric angle valve 22 and the water outlet 4113, for example, the distance between the outlet end of the electric angle valve 22 and the water outlet 4113 is greater than twice the distance between the outlet end of the bubble-making host 10 and the bubble outlet 4114, the first preset time can be smaller than the bubble-making time of the bubble-making host 10. If the bubble-making time of the bubble-making host 10 is short enough, the first preset time can be 0.

[0080] Optionally, the second preset time can be set according to actual needs. In one embodiment, the second preset time is 30 seconds.

[0081] The flushing method includes at least three stages, the first stage is the foaming stage, the second stage is the small water volume wetting stage, and the third stage is the large water volume flushing stage. The flushing of the urinal body 200 is completed through the three stages, which can improve the flushing effect, keep the ceramic inner wall clean, and prevent the accumulation of stains and the yellowing of the inner wall; in the foaming stage, thick foam is formed and sprayed from the foam outlet 4114, and finally forms accumulated foam in the urine collecting trough 203. The foam accumulated in the urine collecting trough 203 is to use the water drop in the small water volume wetting stage to disperse and dilute the foam and finally form a foam shield, so that the sewage in the subsequent flushing process It is not easy to splash out; in the small water volume wetting stage, the half-open electric angle valve 22 reduces the water volume. The small water volume also saves water while wetting the walls. The small water flow impacts the accumulated foam to dilute it and float it on the surface of the deposited water to form a foam shield. When the water flow impacts the accumulated foam, it also has the effect of sterilizing and washing the urine collecting trough 203; in the large water volume flushing stage, the fully opened electric angle valve 22 maximizes the water volume. The large water flow flushes the urine collecting trough 203 and the inner wall of the urinal body 200, which not only washes away the stains but also removes the odor. Moreover, the large water flow impacts the accumulated foam and also plays a secondary sterilization and flushing role on the urine collecting trough 203.

All equivalent structural transformations made by using the contents of the present description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
