The working process of this embodiment is briefly described as follows:
in the initial state, the valve body 32 of the drain control valve 30 keeps closing the valve port 314 under the action of the elastic member 333 and the action of water pressure, that is, the drain control valve 30 is in the closed state, so that the flushing waterway 40 has water stored in the space between the valve port 314 and the drain 21, and since the valve port 314 and the jet port 111 are located below the water level of the water seal 112 of the toilet seat 10, the flushing waterway 40 between the valve port 314 and the jet port 111 is also filled with water, that is, the entire flushing waterway 40 is filled with water in the initial state; the float 61 of the buoyancy mechanism 60 is in a floating state so that the seal plate 62 opens the discharge port 21, and the toilet tank 20 is held in communication with the flush waterway 40 through the discharge port 21.
As shown in fig. 3, 9 and 10, when the toilet seat 10 needs to be flushed, the actuating member is driven, the actuating member drives the first driving rope 81, and the first driving rope 81 further drives the valve core 32 to open the valve port 314, so that the water in the toilet tank 20 and the water in the flushing water channel 40 flow to the jet opening 111 to flush the bottom of the toilet bowl 11. When the valve core 32 moves towards the direction of opening the valve port 314, the valve plate 322 on the valve core 32 compresses the delay cavity 332 (see fig. 10), the check valve (sealing gasket) 334 is far away from the valve plate 322 under the action of water pressure, so as to open the small flow passage aperture 3221, at this time, the flow passage cross-sectional area of the delay channel 331 formed by the small flow passage aperture 3221 and the flow passage gap H is large, so that water in the delay cavity 332 can flow into the flushing water channel 40 through the delay channel 331 relatively quickly (as shown by a dotted arrow in fig. 10), the valve core 32 can open the valve port 314 quickly, and the water in the flushing water channel 40 can be discharged from the valve port 314;
as shown in fig. 11, after the actuating member is released, the valve element 32 moves toward the direction of closing the valve port 314 under the elastic force of the elastic member 333, at this time, the check valve 334 moves to abut against the valve plate 322 under the action of the water pressure, so as to close the small flow passage aperture 3221, at this time, the flow cross-sectional area of the delay passage 331 formed by the small flow passage aperture 3221 and the flow passage gap H is smaller, so that the water in the flushing water channel 40 slowly flows into the delay cavity 332 through the delay passage 331 (as shown by a dotted arrow in fig. 11), and further, the valve element 32 can delay to close the valve port 314, thereby ensuring a sufficient drainage time.
When the water level in the toilet tank 20 drops to a predetermined height, the buoyancy of the float bowl 61 of the buoyancy mechanism 60 is insufficient, so that the sealing plate 62 falls to close the drain opening 21, ending the drainage. The closing of the drain port 21 is controlled by the buoyant mechanism 60, so that the water discharge amount control is more accurate.
After the water discharge is finished, the toilet tank 20 replenishes water, the replenished water can flow into the flushing water channel 40 through the overflowing channel 621 on the sealing disc 62, and the flushing water channel between the valve port 314 and the water discharge port 21 is filled with water because the valve port 314 is in a closed state. When the water of the flushing waterway 40 is filled to the lower surface of the sealing disk 62, the lower surface of the sealing disk 62 is subjected to upward water pressure, so that the resultant force applied to the sealing disk 62 is directed upward, and the sealing disk 62 automatically moves upward to open the drain opening 21 in preparation for the next flushing. Meanwhile, after the water discharge of the toilet seat 10 is finished, the water sealed by the water seal is replenished again, and the water sealed by the water seal can enter the flushing water channel 40 through the jet orifice 111, so that the flushing water channel 40 between the valve port 314 and the jet orifice 111 is filled with water, and the whole flushing water channel 40 is filled with water in an initial state to prepare for the next flushing.

When the toilet seat 10 needs to be flushed, the actuating member is driven, the actuating member drives the first transmission rope 81, and the first transmission rope 81 further drives the valve element 32 to open the valve port 314, so that the water in the toilet tank 20 and the water in the flushing water channel 40 flow to the jet opening 111 to flush the bottom of the toilet bowl 11. When the valve core 32 moves towards the direction of opening the valve port 314, the valve sheet 322 on the valve core 32 compresses the delay cavity 332, the one-way valve (sealing gasket) 334 is far away from the valve sheet 322 under the action of water pressure, so that a gap is formed between the sealing gasket 334 and the valve sheet 322, the flow cross-sectional area of the gap is the flow cross-sectional area of the delay channel 331, namely the flow cross-sectional area of the delay channel 331 is larger at the moment, further, water in the delay cavity 332 can flow into the flushing water channel 40 through the delay channel 331 relatively quickly, the valve core 32 can open the valve port 314 quickly, and the water in the flushing water channel 40 can be discharged from the valve port 314;
after the starting piece is released, the valve core 32 moves towards the direction of closing the valve port 314 under the elastic force of the elastic piece 333, at this time, the one-way valve 334 moves to abut against the valve plate 322 under the action of water pressure, so that a gap is not formed between the sealing gasket 334 and the valve plate 322, the flow cross-sectional area of the flow-through groove on the sealing gasket 334 is the flow cross-sectional area of the delay channel 331, namely the flow cross-sectional area of the delay channel 331 is smaller, so that the water in the flushing water channel 40 slowly flows into the delay cavity 332 through the delay channel 331, the valve core 32 can delay to close the valve port 314, and enough drainage duration is ensured;
when the water level in the toilet tank 20 drops to a predetermined height, the buoyancy of the float bowl 61 of the buoyancy mechanism 60 is insufficient, so that the sealing plate 62 falls to close the drain opening 21, ending the drainage. The closing of the drain port 21 is controlled by the buoyant mechanism 60, so that the water discharge amount control is more accurate.
After the water discharge is finished, the toilet tank 20 replenishes water, the replenished water can flow into the flushing water channel 40 through the overflowing channel 621 on the sealing disc 62, and the flushing water channel between the valve port 314 and the water discharge port 21 is filled with water because the valve port 314 is in a closed state. When the water of the flushing waterway 40 is filled to the lower surface of the sealing disk 62, the lower surface of the sealing disk 62 is subjected to upward water pressure, so that the resultant force applied to the sealing disk 62 is directed upward, and the sealing disk 62 automatically moves upward to open the drain opening 21 in preparation for the next flushing. Meanwhile, after the water discharge of the toilet seat 10 is finished, the water sealed by the water seal is replenished again, and the water sealed by the water seal can enter the flushing water channel 40 through the jet orifice 111, so that the flushing water channel 40 between the valve port 314 and the jet orifice 111 is filled with water, and the whole flushing water channel 40 is filled with water in an initial state to prepare for the next flushing.
