Description

Deodorant waterproof duplicate protection floor drain subassembly

Technical Field

The invention relates to the field of floor drains, in particular to a deodorization and waterproof dual-protection floor drain assembly.

Background

The floor drain is an important interface for connecting a drainage pipeline system and indoor ground, is an important part of a drainage system in a house, has the most basic function of water leakage, but the floor drain can not meet the production and living needs of people by far if only having the water leakage function. Because the peculiar smell in the drainage pipeline easily flows back to the bathroom and the like through the floor drain, the backflow of the peculiar smell can seriously affect the air quality of the bathroom and the living environment of people.

In order to improve the problems of bad smell backflow and water return of the floor drain, people develop various forms of deodorization floor drains which are roughly divided into three types: the first common mode is a water seal mode, a water seal is arranged in the floor drain, the water seal can block the odor flowing backwards from the drainage pipeline in a water storage state, but most of the water seals are not high enough and only 10-20mm in height and are extremely easy to dry, so that the odor in the drainage pipeline overflows into a room, and the odor can directly flow backwards into the room through the floor drain. In addition, if the water return condition occurs, the water seal floor drain cannot be solved; the other type of the floor drain is a mechanical floor drain, a check valve is arranged at the lower part of the floor drain, such as an eccentric block, when water flows through the floor drain, the eccentric block is opened, when no water flows through the floor drain, the eccentric block is closed, so that peculiar smell flowing back from a drainage pipeline can be effectively blocked, but dirt, hair and the like are easily accumulated on the eccentric block, the eccentric block is easily failed by the dirt and the hair, and similarly, the floor drain which is made of silica gel materials, has a flap structure, and is returned after water drainage by using a magnet or a spring and has the check valve structure can be failed by the accumulated dirt and the hair; the last one is a float-type floor drain, but has many defects, such as the same defect as a check valve structure; secondly, the floater can be adsorbed at the drainage port by the drainage port when the drainage amount is slightly larger or is easy to be blocked, so that the drainage is not smooth; and thirdly, the water cannot be effectively blocked in time after the water is reversed.

Therefore, no odor-resistant floor drain in the prior art really solves the problems of odor backflow, water return and inconvenient cleaning.

For example, Chinese patent publication numbers are: CN206616666U, an anti-seepage and anti-odor floor drain announced in 11/7/2017, which comprises an outer floor drain layer and an inner floor drain, wherein the top of the outer floor drain layer is welded with the top of the inner floor drain layer, the inner floor drain comprises an inner floor drain outer layer and an inner floor drain core, a circle of water outlet is arranged at the upper part of the inner floor drain core, and the width of the water outlet extends from the middle part to the top part of the inner floor drain core; the inner floor drain also comprises a water sealing cover connected with the top of the inner floor drain, and a sundry filter screen is arranged below the water sealing cover and connected with the inner wall of the outer layer of the inner floor drain; the outer layer of the floor drain comprises an outer layer wall of the floor drain, a circle of waterproof pressing plate and a water outlet, wherein the upper part of the outer layer wall of the floor drain is outwards arranged, the water outlet is arranged at the center of the bottom of the outer layer of the floor drain, the waterproof pressing plate comprises an extension section and a flat section, a deodorization floating plate is additionally arranged on the upper part of the water outlet, and the width of the deodorization floating plate is larger than that. Although the utility model discloses a simple structure, reasonable in design, low cost, nevertheless there is the palirrhea, the anti-water of peculiar smell, the inconvenient problem of clearance.
