Background

The existing drain valve consists of a valve body, a base and an overflow pipe. Wherein the valve base is communicated with the overflow pipe. Under the normal stagnant water state, the outside air passes through overflow pipe and drain valve base outlet intercommunication. When the overflow phenomenon occurs, water flows from the overflow pipe to the water discharge valve base water discharge port and enters the toilet bowl pipeline. When the drain valve is opened, water flows out through the drain outlet of the drain valve base, and when the drain valve is normally used, the drain outlet of the drain valve base is communicated with outside air through the overflow pipe channel, negative pressure can be generated in the drain channel during draining, and air can be mixed into the drain outlet of the drain valve base together under the action of outside atmospheric pressure, so that the drain channel is not in a pipe full water state, and the drainage speed is reduced.

Patent No. CN 107780495a discloses a technique in which a check valve is provided inside an overflow pipe, and a float is provided above the check valve. Under normal stagnant water condition, the check valve is in the closed condition, therefore during the drain valve drainage, and outside air can not flow to valve base outlet from the overflow pipe, and valve base outlet is in full pipe water state almost, and then produces the siphon, and siphon effect makes the drainage speed in base outlet improve. This technique has two drawbacks. Firstly, the one-way valve is easy to fall off from the overflow pipe in the transportation process, and the one-way valve cannot be reset normally during working, so that sealing failure is caused; secondly, when the drain valve drains water, the one-way valve can be arched by the flush water, air is not thoroughly isolated, the drainage channel can contain partial air, and the siphon effect is not obvious.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

an overflow assembly comprises an inner hollow shell, wherein a water inlet cavity and a water discharge cavity which are distributed up and down are separated by a horizontal partition plate inside the shell. The top of the shell is connected with a water inlet pipe communicated with the water inlet cavity, and the bottom of the shell is connected with a water discharge pipe communicated with the water discharge cavity. The top of the horizontal partition plate is fixedly provided with an annular water baffle, and the outer side of the horizontal partition plate is provided with a water through hole for communicating the water inlet cavity and the water drainage cavity. A water sealing area is formed by enclosing the annular water baffle and the horizontal partition plate, an overflow port is formed in the top of the annular water baffle, the water inlet pipe extends into the water sealing area, and the position of the end face of the bottom of the water inlet pipe is lower than that of the overflow port.

Further, the shell include upper cover, interior box and lower cover, the both ends of interior box respectively with upper cover and lower cover fixed connection, the inlet tube set firmly on the upper cover, horizontal baffle sets firmly inside the interior box, the drain pipe set firmly on the lower cover.

Preferably, the lower cover and the drain pipe are of an integrally formed structure.

Furthermore, in order to better realize the discharge of overflow water, the water passing holes are provided with a plurality of water passing holes which are uniformly distributed along the circumferential direction of the horizontal partition plate.

The utility model discloses following beneficial effect has: under normal conditions, the bottom end of the water inlet pipe is positioned below the water sealing surface of the water sealing area. When the overflow phenomenon occurs, the water level height of the water sealing area rises, and the water level overflows the annular water baffle plate to realize overflow. Because of the inlet tube bottom accomplishes and is in the air isolation state under the water cover, can realize the overflow function when overflow assembly installs alone. When the overflow assembly is installed on the drain valve, the external air cannot flow to the valve base water outlet from the overflow pipe, the valve base water outlet is almost in a full pipe water state, siphon is generated, and the drainage speed of the base water outlet is greatly improved through the siphon effect when the drain valve drains water.
