Description

Floor drain core

Technical Field

The utility model relates to the technical field of floor drains, in particular to a floor drain core.

Background

The floor drain is an important interface for connecting a drainage pipeline system with the indoor ground, is used as an important component of the drainage system in a house, has good performance, directly influences the quality of indoor air, and is very important for controlling the peculiar smell of a bathroom.

Currently, floor drains on the market are mainly divided into two types: water seal type floor drain and mechanical floor drain.

The principle of the water seal type floor drain is mainly to isolate a sewer pipe from the indoor space by utilizing water, so that the odor anti-string of the sewer pipe and the entry of mosquitoes are prevented. The water seal type floor drain is generally divided into a deep water seal and a shallow water seal. As the name implies, the floor drain is named according to the height of the water seal, and the deodorization effect of the deep water seal floor drain is better than that of the shallow water seal. However, most of floor drains on the market have water seal heights which do not reach 50mm of the national standard, so that the deodorization performance is poor, and if the floor drain is not used for a long time, water is evaporated, the water seal layer is dried up, so that odor in a sewer pipe overflows into a room, and the sewer flow rate is influenced by liquid flow reversely for many times.

The other is a mechanical floor drain, and the mechanical floor drain mainly utilizes the gravity of water to realize the functions of water drainage and deodorization. When water is drained, gravity generated by water flow can push the baffle plate away, so that a drainage effect is achieved; when no water is discharged, the baffle is automatically closed to block the connection between the sewer and the room, thereby achieving the deodorization effect. Although the self-sealing floor drain has better drainage effect, the sealing effect is unsatisfactory, and the problems of odor reversion, mosquito breeding and the like are easy to occur due to the failure of opening and closing caused by the foreign matters of dirt and hair.

It is known from the above that no matter the floor drain is a water seal type floor drain or a mechanical floor drain, certain gas returning condition exists, so that the use is inconvenient. In addition, in the above-mentioned technique, the structure of floor drain casing is complicated, and inconvenient processing, and processing cost is high.

Based on the above problems, we have devised a floor drain core to solve the above problems.
