a floor drain

Abstract

The invention discloses a novel floor drain; a liquid level sensor is arranged on the inner sidewall of a drain basket; the liquid level sensor is used for detecting whether the floor drain can achieve drainage; a water stopper is used for plugging a water seal main body, so that the emission of odor in a sewer pipe is prevented; and when the liquid level sensor detects the drainage, the water seal main body is opened by the water stopper and water is discharged into the sewer pipe. With the adoption of the structures, the interior of the water seal main body of the floor drain is simple, and the drainage speed of the floor drain is not affected, so that smooth drainage of the floor drain is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sewage discharge, in particular to a floor drain. Background technique [0002] The floor drain is an important interface connecting the drainage system with the indoor floor. As an important part of the drainage system in the residence, its performance directly affects the quality of the indoor air, and is very important for indoor odor control. Present floor drain comprises funnel, funnel cover and water seal main body. The water seal body is connected to the lower end of the funnel, and the funnel cover is covered on the upper end of the funnel. A filter is arranged in the funnel. In order to prevent the odor in the downpipe from escaping from the floor drain, the main body of the water seal will be designed with a trap, but the floor drain with this structure will affect the drainage speed, making the floor drain not drain smoothly. There is also an anti-odor structure designed in the main body of ...

Problems solved by technology

In order to prevent the odor in the downpipe from escaping from the floor drain, the main body of the water seal will design a trap, but the floor drain with this structure will affect the drainage speed, making the floor drain not drain smoothly

There is also an anti-odor structure designed in the main body of the water seal. For example, the utility model patent No. ZL2011203704215 discloses a technical solution for a new type of anti-odor floor drain. In the middle of the main body of the water seal, occupying the internal space of the main body of the water seal will also affect the drainage speed of the floor drain, making the drainage of the floor drain difficult
