- the water level of the lower water chamber 52 continues to slowly decrease to form a negative pressure in the lower water chamber 52. When the negative pressure reaches a certain level, the siphon is passed through the siphon.
- the water in the water storage chamber 51 is sucked into the lower water chamber 52 until the water in the water storage chamber 51 is interrupted by the suction siphon, and the water level of the water tank and the water level of the lower water chamber 52 continue to decrease until the flushing is completed; meanwhile, the water level of the water tank drops to
- the pontoon 31 again drives the swing arm 3 to deflect, so that the back pressure pad 21 opens the back pressure hole 22, the pressure relief pad 13 is separated from the water stop surface 14, and the water inlet hole 15 is opened to realize the water inlet again.
- part of the water is guided by the water guiding channel 7 into the water storage chamber 51, and the water also enters the lower water chamber 52 and the upper weight chamber 62.
- the floating tube 31 drives the swing arm 3 to deflect, and the back pressure pad 21 re-close the back pressure hole 22, the water stop pad 13 Back pressure to block the inlet hole 15 to achieve sealing.
- the water inlet valve will always be in the water.
- part of the water is still guided into the water storage chamber 51 by the water guiding tank 7, because the water inlet valve always enters the water, the water level in the water storage chamber 51 continuously rises, and the float 55 in the water storage chamber 51 is driven.
- the first magnetic element 56 of the float 55 is aligned with the second magnetic element 92 of the latch 91, as shown in FIG.
- the pin 91 is pulled out from the lever 9 by magnetic force to release the positioning of the lever 9, the latch 91 compressing the return spring 93, the lever 9 and the connecting rod 8 are deflected by the energy storage spring 80 (in this embodiment, the lifting rod 83 is pushed down by the energy storage spring 80 to lower the first link 81, the first link 81 Cooperating with the shifting fork 94 to drive the lever 9 to deflect, the first connecting rod 81 also drives the second connecting rod 82 to deflect, and the connecting rod 8 (specifically, the second connecting rod 82) drives the eccentric shaft 41 to rotate, as shown in FIG. It is shown that the eccentric shaft 41 rotates to form a seating space for the sealing water piston 4 to rise. 4 by the piston action of the water pressure rises inlet hole 15 closed, the intake valve sealing.
- the weight level of the small floating bucket 6 is relatively consistent with the water level of the water tank, and the small floating bucket 6 cannot produce the counterweight and is always in the In the floating state, the lower chamber 52 of the water storage cylinder 5 is always connected to the atmosphere, and the water line is also relatively opposite to the water tank, and no negative pressure is generated, and the water in the water storage chamber 51 is not siphoned, so that the water is stopped several times.
- the water in the water storage chamber 51 is continuously accumulated, and the water level in the water storage chamber 51 is continuously increased, and the float 55 in the water storage chamber 51 is caused to rise accordingly, when the float 55 is first.
- the magnetic element 56 is aligned with the second magnetic element 92 of the pin 91, the pin 91 is pulled out from the lever 9 by the magnetic force to release the position, and the lever 9 and the link 8 are deflected by the energy storage spring 80, and the link 8 drives the eccentricity.
- the eccentric shaft 41 drives the water sealing piston 4 to rise to close the water inlet hole 15, so that the water inlet valve stops flowing.
