The specific working process of this embodiment is as follows:
as shown in fig. 4: under normal conditions, when the water in the water tank is full to a preset position, the buoy 12 in the drainage main body floats, the valve core is sealed with the water outlet 1301 under the action of self gravity and the pressure of the water in the water tank so as to close the water outlet 1301, and the water in the water tank is prevented from flowing out of the water outlet 1301; meanwhile, under the action of the valve core, the transmission part 401 of the lifting rod props against the capsule body 3, at the moment, the power source is not opened, and the capsule body 3 is naturally contracted;
as shown in fig. 5: when water needs to be drained, the water inlet mechanism is opened, water enters the bag body 3 from the water diversion channel through the connector 1, the bag body 3 is jacked open to enable the bag body 3 to expand, the bag body 3 expands and butts against the transmission part 401 of the lifting piece 4 to move downwards, at the moment, the driving part 402 of the lifting piece 4 moves upwards and drives the valve core to move upwards together, the sealing part of the valve core opens the water outlet 1301, and water in the water tank flows out of the water outlet 1301 to a toilet pipeline; meanwhile, as the buoy 12 still keeps a floating state, the clamping part 702 of the valve core is in abutting limiting fit with the limiting part 1201 of the buoy 12, so that the valve core is kept in a state of opening the water outlet 1301, and at the moment, even if water supply to the capsule body 3 is stopped, the valve core can still delay falling to achieve the purpose of prolonging the drainage time;
as shown in fig. 6: along with the drainage of water in the water tank, the water level is lowered, water in the separation cavity 601 can be slowly drained from the water inlet 603, and the buoy 12 slowly falls into an inclined state, so that the limiting part 1201 of the buoy 12 is separated from the clamping part of the valve core;
as shown in fig. 7: when the water inlet mechanism stops supplying water to the capsule body 3 and the limiting part 1201 of the buoy 12 is completely separated from the clamping part 702 of the valve core, the valve core falls down under the action of self gravity, and the sealing part is in sealing fit with the water outlet 1301 again to prevent water in the water tank from flowing out of the water outlet 1301; meanwhile, the transmission part 401 of the lifting piece 4 moves upwards to push the capsule body 3 upwards, and water in the capsule body 3 is extruded to a brush ring water channel of the toilet, so that the capsule body 3 is recovered to a contraction state.
When the water is drained and the valve core reseals the water outlet 1301, the water level in the water tank rises, and water enters the separation chamber 601 from the water inlet 603 to drive the buoy 12 to float again, so as to return to the initial water storage pre-drainage state to wait for the next circulation.
The water discharge amount of the water discharge body is controlled by setting the adjusting member 8 for adjusting the size of the water inlet 603 to adjust the water discharge speed of the compartment 601, thereby controlling the falling time of the buoy 12.
This scheme passes through the power supply and the switching of utricule 3 cooperation in order to control the drain valve, need not manual the pressing, convenient operation, laborsaving to inflation or shrink through control utricule 3 can be controlled the switching of drain valve, simple structure, compactness.
