[0043] Working principle:

[0044] (1) Static: the first flush key 110 and the second flush key 120 reset under the action of the first reset spring 140 (such as Figure 10 ), at this time, the reciprocating piece 260 has not been pulled up, the plug 250 tightly blocks the second pressure relief hole 240 under the action of the second reset spring 271 (such as Figure 3 ), and simultaneously, the baffle 320 of the sewage outlet 311 is reset under the torsional force of the torsional spring 330 through the meshing transmission of the first gear 340 and the second gear 350, that is, the baffle 320 is in the vertical state (such as Figure 7 ).

[0045] (2) Driving: the first flush key 110 is pressed, the first flush key 110 is pushed to rotate through the key post 130, and then the first flush key 110 pulls and lifts the first wire 400 connected thereto; since the other end of the first wire 400 is connected with the reciprocating piece 260, the reciprocating piece 260 is pulled up, the plug 250 moves outward under the action of the inclined surface part 261 of the reciprocating piece 260, the second pressure relief hole 240 is loosened, the second pressure relief hole 240 is connected with the pressure relief channel 291, and the first electromagnetic valve 210 can start flushing (such as Figure 4 ); at the same time, since the lower end of the reciprocating piece 260 is connected with the third wire 600, the third wire 600 pulls the second gear 350 to rotate, the first gear 340 rotates, and the first gear 340 drives the baffle 320 to rotate around the rotating shaft 321 to the horizontal state, so as to block the sewage outlet 311.

[0046] (3) When the sewage outlet 311 is blocked by the baffle 320, the first flush key is loosened when the water level rises to an appropriate height after the first electromagnetic valve 210 continuously flushes, at this time, the second gear 350 rotates under the torsional force of the torsional spring 330, and the baffle 320 is reset (such as Figure 8) ; meanwhile, the rotation of the second gear 350 will pull the third wire 600, thus pulling the reciprocating member 260 to move downward to reset, and the plug 250 is reset under the elastic force of the second reset spring 271 to block the second pressure relief hole 240, at this time the first electromagnetic valve 210 immediately stops flushing.

[0047] (4) press the second flushing button 120 again to spray water by aid siphon, the action principle of the second electromagnetic valve 220 is similar to the above, the difference is that the second electromagnetic valve 220 does not have a wire to connect the flushing valve manual switch and the shifter switch, that is, when the second flushing button 120 is pressed, the baffle 320 does not act, only the toilet bottom siphon shower head 910 sprays water, and the reciprocating member 260 of the second electromagnetic valve 220 is reset by the third reset spring 281 (as Figure 5 ).
