Drain device

Abstract

The invention relates to a drain device, which comprises a body, a top cover assembly and a bottom cover. The body is provided with an inner space, and a plurality of permeable parts running through the inner space. The top cover assembly is separably arranged on the top of the body and comprises a top cover and a plurality of connecting pieces. The connecting pieces extend a certain length from the bottom of the top cover. The bottoms of the connecting pieces are connected with each other. Each connecting piece is provided with an upper elastic sheet and a lower elastic sheet. The elastic sheets are provided with convex parts towards the outside of the top cover. The bottom cover is separably arranged on the bottom of the body. A certain space is formed between the bottom cover and the body. The bottom cover is provided with a permeable part. Due to the combination of the components, an outer edge of each convex part protrudes out of the body and an outer side wall of the bottom cover, and can be applied with a force so that the convex part inwards contracts toward the inside of the top cover, and the convex part can be automatically popped up when the external force is eliminatedso that the outer edge of the convex part protrudes out of the body and the outer side wall of the bottom cover again.

Description

technical field [0001] The invention relates to a falling water head device, especially a water falling head device with integrated structure, which can be quickly disassembled, assembled and cleaned, easy to use, and has the functions of drainage, filtration and sanitation, and is suitable for the application and manufacturing related fields of the falling water head device. . Background technique [0002] In addition to providing drainage, it also has a filtering function to prevent debris such as hair and vegetable chips from directly falling into the drainage pipe and causing blockage. [0003] There are many kinds of common falling water head structures. The most basic structure is to screw a cover with holes and grooves on the drainage holes. The water can be discharged into the drainage pipes through the holes and grooves. It is blocked on the cover body, but its disadvantage is that the cover body must be screwed open for cleaning, which is extremely inconvenient; t...

Problems solved by technology

[0003] There are many kinds of common drain head structures. The most basic structure is to bolt a cover body with holes and grooves on the drainage hole. It is blocked on the cover body, but its disadvantage is that the cover body must be unscrewed to be cleaned, which is extremely inconvenient; therefore, it can be seen that an improved drain head device is generally installed in the drain hole of the sink of the sink, which mainly includes A movable upper cover, a rubber auxiliary cover, and a filter body with a certain capacity. Usually, a space with an outer diameter slightly larger than the drain pipe is provided at the place where the drain pipe connects to the drain hole, and the filter body can be installed in it. , and then sequentially cover the auxiliary cover and the upper cover on the filter body, the upper cover can completely close the drain hole, so that the water in the tank will no
