Description

Rapid drainage device for toilet water tank

The present invention relates to a rapid drainage device for a toilet water tank, in particular to a rapid drainage device that reduces air resistance during drainage.

In the field of flush toilets, the water tank is equipped with related drainage structures such as overflow pipes, drainage pipes, and water stop devices, and the water stop valve serves as the main controller of water outflow from the water tank. The relevant content of the drainage structure can be found in CN 206503204U, CN 2466254Y and CN 103590467A and other patents.

When the conventional drainage structure is implemented, the water stop valve is driven to stop blocking the drainage pipe from the outside, so that the water inside the water tank can flow to the toilet through the drainage pipe. However, the conventional drainage structure has a problem that it is difficult for the water in the water tank to enter the drainage pipe. The reason is that one end of the overflow pipe is connected to the drainage pipe. When the water stop valve is opened, the gas in the overflow pipe flows toward the drainage pipe under pressure, and Discharge through the opening connecting the drain pipe and the water stop valve. That is to say, when the water stop valve is opened, the water in the water tank is going to flow into the drain pipe, and the gas in the overflow pipe is going to be discharged from the drain pipe. This will cause the water flow to collide with the gas, which is not conducive to the rapid flow of water. into the drain pipe.

Take CN 206503204U as an example. In order to solve the above-mentioned problems, the drainage valve structure is provided with a water-blocking piece facing the outlet of the overflow channel. However, the purpose of the water-blocking piece is to guide the part intended to flow into the drainage channel. Water flows into the overflow pipe, causing the water entering the overflow pipe to form a water seal at the outlet of the overflow channel, thereby inhibiting the flow of gas in the overflow channel and colliding with the water flow into the drainage channel. From the above it can be seen that The actual function of the water retaining sheet of CN 206503204U is to guide the water flow, so that part of the water flow from the water tank forms a water seal, and the remaining part maintains water drainage. However, the aforementioned structure cannot provide the function of rapid water release. In addition, the water retaining sheet and the overflow There is a certain distance from the outlet of the flow channel, and there is concern that the water flow cannot be specifically restricted. Therefore, the applicant in this case took into account the shortcomings caused by the aforementioned drainage structure, and therefore worked hard to develop a drainage structure that is more conducive to rapid drainage.

The main purpose of the present invention is to solve the problem that the conventional structure cannot specifically reduce the air resistance during drainage.

In order to achieve the above object, the present invention provides a rapid drainage device for a toilet water tank, which includes a drainage structure and a water stop structure.

After the water stop valve is operated, it opens relative to the rubber valve seat and allows the inner space of the main pipe to communicate with the outside. The rubber valve seat has a connection with the rubber valve seat. A bevel-fitting base body, an opening formed in the base body and connected to the inner space of the main pipe, and at least one stop piece extending from the base body into the main pipe, the stop piece being close to the inner wall of the main pipe and facing The communication port, the stop piece covers at least 50% of the area of the communication port, wherein the stop piece opens when the water stop valve unblocks the opening to allow water in a toilet tank to enter the main pipe. The stopper piece blocks the air resistance from the communication port under the action of water pressure. When the water stop valve closes the opening, the stopper piece does not completely close the communication port, causing the overflow manifold to be connected to the opening. The supervisor maintains connectivity.

Following the above, the water stop structure 20 includes a rubber valve seat 21 at one end of the main pipe 11 with the slope 112, and a water stop valve 23 pivotally connected to the overflow manifold 12. The water stop valve 23 and the rubber The valve seat 21 cooperates. When the water stop valve 23 is not operated, it blocks the communication of the rubber valve seat 21 and restricts the main pipe 11 from being able to communicate with the outside. Once the water stop valve 23 is operated, it will be relative to the rubber valve seat. 21 is opened and allows the inner space of supervisor 11 to communicate with the outside. In addition, the rubber valve seat 21 is made of rubber material as the name suggests, which is different from the conventional hard material. The rubber valve seat 21 includes a seat 211 provided on the pipe body 111, an opening 212 formed on the seat 211, and at least one stopper 213 extending from the seat 211 to the main pipe 11.

Enter the main room 11, as shown at 50. At this moment, the overflow manifold 12 discharges gas toward the communication port 113. The stopper piece 213 blocks the air resistance from the communication port 113 due to water pressure, allowing water to smoothly enter the space inside the main pipe 11. and be discharged. When the water stop valve 23 pivots again and closes the opening 212, the water stop valve 23 blocks the communication between the main pipe 11 and the outside. At this time, because the stop piece 213 does not completely close the communication opening 113, the overflow The flow manifold 12 is still connected to the main pipe 11 , and the overflow manifold 12 can still provide water flowing into it to flow into the main pipe 11 through the communication port 113 when the water stop valve 23 is not opened.
