s30, after the water storage device is filled with water for t1 time, the first water inlet control switch 22 is closed, the water outlet assembly 36 is opened immediately, the water storage device 3 starts to drain, and the water discharged by the water storage device flows to the water supply port of the toilet bowl through the first water outlet pipe 23 to wash the toilet bowl; the first water inlet control switch 22 is turned off, and then the second water inlet control switch 25 is turned on, so that the second water outlet pipe 26 is enabled to outlet water, and the outlet water of the first water outlet pipe 23 and the outlet water of the second water outlet pipe 26 are converged by the converging box 4 to flush the toilet.
According to the control method of the toilet flushing mechanism, after the first water inlet control switch 22 is closed, the water storage device 3 automatically discharges water from the first water outlet pipe 23, at the moment, the second water inlet control switch 25 is opened, the water pressure of the water supply source is utilized to enable the second water outlet pipe 26 to discharge water, and the water pressure of the water supply source is not split; meanwhile, the water channel of the water storage device 3 and the water channel of the water supply source are utilized to flush the toilet together, so that enough flushing water is also available when the pressure is low, and the flushing effect is ensured.
Example two
