Description

technical field

The invention relates to the technical field of sanitary ware, in particular to a water tank flushing device with improved flushing capacity and a toilet with the same.

Background technique

Among the existing flushing devices for flushing toilets, hidden water tank flushing devices are more and more widely used. Due to the flexible layout of toilets in various households, the specifications of hidden water tanks need to be diverse to adapt to various occasions. Among them, the low-profile hidden water tank flushing device has been favored by consumers because of its low installation height and flexible layout. Concealed water tanks are usually equipped with water inlet valves, drain valves, driving devices and water tank accessories. When draining, press the driving device to start the drain valve, and the water in the water tank rushes to the urinal of the toilet under the effect of gravitational potential energy. The flushing effect of the water tank flushing through the potential energy of water mainly depends on the level of potential energy, that is, high potential energy has good flushing effect, and low potential energy has poor flushing effect.

However, the short concealed cistern flushing device, because of the low installation height of the cistern and the low water level, has low potential energy of the water in the cistern and poor flushing effect, making it difficult to match most toilets on the market. Some existing concealed water tank flushing devices increase the momentum by enlarging the water tank outlet and increasing the working water level as much as possible, but the actual improvement effect is not obvious.

This embodiment also provides a toilet (not shown in the figure), comprising a seat body provided with a urinal and any of the above-mentioned water tank flushing devices with improved flushing capacity.

The working principle of this embodiment is briefly described as follows:

In the initial state (that is, under normal conditions), water is stored in the water storage chamber 11, as shown in Figures 2 to 4, the spool 32 of the drain valve 3 is located at a lowered position to close the drain (that is, close the drain channel 331), and the drain valve 3 water stop, the abutting part 7 is at the first position, the stopper 413 is at the stop position, and the second buoy 411 is at the low position (specifically at the first drop position), at this time, the second buoy 411 has not completely fallen, The second buoyant bucket 411 is still in the state of floating due to the buoyancy of the water, but the second buoyant bucket 411 is limited by the position limiting member 413 and remains at the first falling position. Under the action of the elastic force of the first elastic member 414 Next, the gasket 415 on the movable part 412 presses against the first valve body 42 and closes the pressure relief hole 45, and the water stop part 43 moves to the water stop position under the back pressure of the back pressure chamber 44 to cut off the water inlet channel 421 and the communication between the water outlet channel 422, the auxiliary flushing valve 4 stops water;

When flushing, the spool 32 of the drain valve 3 is driven by the starting mechanism to rise from the lowered position to open the drain port (that is, to open the drain channel 331) to open the drain valve 3, and then control the drainage of the water tank 1; , as shown in Figure 5 and Figure 6, the abutting portion 7 on the spool 32 abuts and cooperates with the limiter 413 to drive the limiter 413 to rotate from the limit position to the abdication position, at this time, the limiter 413 Release the limit to the second floating bucket 411, the second floating bucket 411 floats up under the buoyancy of the water, and the second floating bucket 411 drives one end of the movable part 412 to lift up through the screw rod 416, so that the other end of the movable part 412 The sealing gasket 415 opens the pressure relief hole 45, the first elastic member 414 is compressed, and the second buoy 411 lifts up the screw rod 416 to maintain the limit member 413 at the position of the relief, and the water pressure of the water stop member 43 in the water inlet channel 421 Under the action, it moves to the water inlet position, and the water inlet channel 421 and the water outlet channel 422 are connected, so that when the drain valve 3 is opened, the flushing aid valve 4 is also opened, so that the water flow discharged from the drain channel 331 of the drain valve 3 and the flushing aid The water flow discharged from the water outlet channel 422 of the valve 4 flows into the urinal together after converging in the first drain pipe 5 to flush the urinal at the same time, which greatly increases the flushing force and improves the flushing effect; wherein, as shown in Figure 5, the valve After the core 32 drives the limiter 413 to rotate from the limit position to the relief position, the contact part 7 loses contact with the limiter 413, and the valve core 32 continues to rise to the rising position to complete the opening of the drain valve 3;

When the water level in the water storage chamber 11 drops to a certain height, the second floating bucket 411 first begins to drop, and when the second floating bucket 411 drops to the first falling position, it continues to drop as the water level in the water tank 1, as shown in Figure 7 As shown, after the water tank 1 is drained, the second floating bucket 411 descends to the second falling position. At this moment, the second floating bucket 411 falls completely. Under the action of gravity, the position is reset to the limit position, so as to limit the second floating bucket 411 from floating to a high position when the water tank 1 is filled with water next time. The sealing gasket 415 on the top will close the pressure relief hole 45 under the combined action of the gravity of the second floating bucket 411 and the elastic force of the first elastic member 414, and the flushing valve 4 will stop water; when the second floating bucket 411 drops to the second After the falling position, the spool 32 begins to descend. During the process of the spool 32 returning from the raised position to the lowered position, as shown in FIG. The second position is to give way to the limiter 413, so that the spool 32 can be smoothly reset to the down position to close the drain of the drain valve 3; after the spool 32 is reset to the down position (that is, the drain valve 3 closes the drain), it will The connecting part 7 rotates from the second position to the first position under the action of its own gravity; then, the water inlet valve 8 is opened to replenish water to the water storage chamber 11, and as the water level in the water storage chamber 11 rises, the second floating The bucket 411 floats up from the second drop position to the first drop position due to the buoyancy of the water, and the stopper 413 in the limit position stops the second buoyant bucket 411 at the first drop position, and the water tank flushing device returns to the initial position. state.

In other embodiments, it can also be set so that the outlet end of the flow pipe passes through the drainage channel and directly or indirectly communicates with the urinal, so that the pressure water flowing out of the water outlet channel can also flow to the urinal through the drainage channel.
