This kind of drain head 2 has a leaky pan 23 It can be disassembled for cleaning and draining.

Contents of the invention

The main purpose of the utility model is to provide an improved structure of the drain head which can prevent the reverse flow of external water.

In order to achieve the above purpose, the utility model adopts a sink head with an improved structure, which includes a seat, a leakage tray, a leak-proof gasket and a cover, wherein the seat is preset on the ground and is a funnel-shaped round seat The body has a concave stepped groove near the middle section, a hollow ring-shaped anti-leakage gasket straddles the stepped groove, and a disc-shaped leaking plate is arranged underneath, and a notch with internal threads is arranged on the top of the seat. The cover body is in the shape of a round cap with a slightly  shape, and its top cover surface is provided with protruding screw ears, and a coil with external threads is provided on the periphery. The bottom end face of the ring can just press against the leak-proof gasket.

In addition, a stud can be extended from the bottom of the cover, and a waterproof gasket can be directly threaded and locked.

At the same time, the cover body and the leak-proof gasket can be designed in one piece.

A water drop head with an improved structure of the above-mentioned structure can be used for general drainage at ordinary times. When it encounters possible drainage and backflow, it can be sealed with a cover so that it has the effect of preventing backflow and preventing odor and bedbugs. entry.
