The reciprocating member 260 has an inclined portion 261 and an inner recess 262. The reciprocating member 260 can move up and down along the second accommodating chamber 280. When the inclined portion 261 passes through the through groove 251, the plug 250 is squeezed by the inclined portion 261 and moves, so that the plug 250 is separated from the pressure relief hole. When the inner recess 262 reaches the through groove 251, the plug 250 blocks the second pressure relief hole 240. The second pressure relief hole 240 is opened and closed by the linkage of the wire, the plug 250, the reciprocating member 260, the second reset spring 271 and other parts, so that the flush valve starts and stops flushing. The reciprocating member 260 and the plug 250 are arranged perpendicular to each other, and the plug 250 is driven to move outward by the inclined portion 261. The reciprocating member 260 is reset under the action of the torsion spring 330, and the plug 250 is reset under the action of the second reset spring 271.

[0036] In some embodiments of the present invention, a third return spring 281 is provided in the second accommodating chamber 280 of the second solenoid valve 220, and the third return spring 281 is sleeved on the reciprocating member 260.

When the baffle 320 is rotated by the driving force of the third wire 600, the torsion force of the torsion spring 330 can reset the baffle 320, and the torsion force will also act on the third wire 600, thereby resetting the reciprocating member 260.

[0040] In some embodiments of the present invention, a second limit plate 380 and a third limit plate 390 are fixedly provided on the outside of the shifter body 310 for limiting the rotation angle of the second gear 350. When the baffle 320 is in a vertical state, the second gear 350 abuts against the second limit plate 380.

[0043] Working principle:

[0044] (1) In static state: the first flush button 110 and the second flush button 120 are reset under the action of the first reset spring 140 (eg Fig.10 ), at this time, the reciprocating member 260 has not been pulled up, and the plug 250 tightly blocks the second pressure relief hole 240 under the action of the second return spring 271 (such as Figure 3 ); At the same time, under the torsion force of the torsion spring 330, the first gear 340 and the second gear 350 are meshed and driven to indirectly drive the baffle 320 of the sewage outlet 311 to reset, that is, the baffle 320 is in a vertical state (such as Figure 7 ).

[0045] (2) When driving: the first flush button 110 is pressed, and the button column 130 on the first flush button 110 pushes the first lever 720 to rotate, thereby pulling up the first wire 400 connected thereto; since the other end of the first wire 400 is connected to the reciprocating member 260, the reciprocating member 260 is pulled up, and under the action of the inclined portion 261 of the reciprocating member 260, the plug 250 moves outward, and the second pressure relief hole 240 is released, so that the second pressure relief hole 240 is connected to the pressure relief channel 291, and the first solenoid valve 210 can start flushing (such as Figure 4 At the same time, since the lower end of the reciprocating member 260 is connected to the third wire 600, the third wire 600 pulls the second gear 350 to rotate, and the first gear 340 rotates accordingly, and the first gear 340 drives the baffle 320 to rotate around the rotating shaft 321 to a horizontal state, thereby blocking the sewage outlet 311.

[0046] (3) When the sewage outlet 311 is blocked by the baffle 320, as the first solenoid valve 210 continues to flush water, the first flush button is released when the water level rises to an appropriate height. At this time, the second gear 350 rotates under the torsion force of the torsion spring 330, driving the baffle 320 to reset (such as Figure 8); At the same time, the rotation of the second gear 350 will pull the third wire 600, thereby pulling the reciprocating member 260 to move downward and reset. The plug 250 is reset under the elastic force of the second reset spring 271 and blocks the second pressure relief hole 240. At this time, the first solenoid valve 210 immediately stops flushing.

[0047] (4) Press the second flush button 120 again to assist the siphon spraying. The operating principle of the second solenoid valve 220 is similar to the above, except that the second solenoid valve 220 does not have a wire to connect the manual switch of the flush valve and the shifter switch in series. That is, when the second flush button 120 is pressed, the baffle 320 does not move, and only the siphon nozzle 910 at the bottom of the toilet bowl sprays water. The reciprocating member 260 of the second solenoid valve 220 is reset by the third reset spring 281 (as shown in FIG. Figure 5 ).
