Drainage device

The present invention relates to a drain for a water tank, and more particularly to a drain device for a drain valve.

Background technique

Due to the rapid development of the global economy, the shortage of water resources has become an urgent problem for governments. As a device with a large amount of water, the toilet is undoubtedly getting more and more attention in today's water shortage. However, most of the current water tank accessories, whether it is a single-row drain valve or a double-row drain valve, will have a "necking" effect on the drain port, which will hinder the drain speed of the water tank, resulting in insufficient flushing of the toilet, in order to ensure The flushing effect of the toilet often causes waste of water. 1 is a schematic view showing the structure of a two-row drain valve in the prior art, the drain valve body 11' is mounted on the drain base 21', the button bracket 15' is mounted on the upper portion of the body 11', and the full row of buttons 13', half row The button 14' is mounted on the button bracket 15', the overflow tube 19' is mounted on the side of the body 11', the drain base 21', and the half row of buttons 14' is aligned with the half row of floats 42' by the half row of adjustment rods 41' In association, the upper periphery of the drainage base 21' is provided with a water stop surface 211', and the bottom of the drainage base 21' is provided with a water outlet communicating with a drain pipe (not shown), and the draining mechanism 31' includes a lining plate , a water stop rubber pad and an inner sleeve, the water stop rubber pad is installed at the bottom end of the inner sleeve through the lining plate, the draining mechanism 31 ′ is installed in the body 11 ′, and the full row of buttons 13 ′, the half row of buttons 14 ′ In association with the movement, the drainage mechanism 3 can be moved in the water stop position and the drainage position in the body 11'. When the water is stopped, the drainage mechanism 31' is closed on the water stop surface 211' of the drainage base 21', and the drainage base 21' The drain is closed; when draining, the drain mechanism 31 ' moves up While in the drainage position, the water stop surface 211 ' of the drainage base 21' is not closed, the drain opening of the drainage base 21' is opened, and the water in the water tank can be discharged through the drain port of the drainage base 21' into the drain pipe, and Then enter the toilet to wash the toilet. In the drainage structure of the prior art, when the water in the water tank passes through the drain port of the drainage base 21', the water flow is "necked" due to the suddenly contracted drain structure, which causes the water flow to be blocked, hindering the water tank. The drainage speed causes insufficient flushing of the toilet. Summary of the invention
