Sewage floor drain capable of preventing odor from flowing out and automatically opening and closing by buoyancy

Abstract

The invention discloses a sewage floor drain capable of preventing odor from flowing out and automatically opening and closing by buoyancy, and relates to the technical field of sewage. The sewage floor drain comprises a foundation, wherein a sewage pipe is fixedly connected to the inner wall of the foundation, a shell fixedly connected with the top of the foundation is fixedly connected to the top of the sewage pipe, and sliding wheels symmetrical on two sides are movably connected to the bottom of the middle part of the shell; and the middle part of the shell is movably connected with a connecting column, the inner top wall of the connecting column is fixedly connected with a spring I, and the bottom of the spring I is fixedly connected with a toothed bar connected with the bottom of theconnecting column in an inserted mode. According to the sewage floor drain capable of preventing the odor from flowing out and automatically opening and closing by the buoyancy, through cooperative use of a floating plate and a blocking block, in an initial state, the floating plate and the connecting column are located at the bottom under the action of self gravity, and meanwhile, the blocking block blocks the bottom of the shell, so that upward permeation of gas in the sewage pipe is effectively reduced, therefore the odor outflow preventing effect is achieved, the air quality of a shower cubicle is effectively improved, and the comfort level of a user is improved.

Description

technical field [0001] The invention relates to the technical field of sewage, in particular to a sewage floor drain with odor-proof air flowing out and automatically opening and closing by buoyancy. Background technique [0002] Floor drain is a kind of sewage equipment that facilitates the discharge of domestic sewage. Most of them are installed in the shower room to facilitate the discharge of sewage generated by bathing into the sewage pipeline, so that the sewage flows to a fixed location and concentrates, which is convenient for post-processing. [0003] Most of the current floor drains are straight through the pipe orifice, and the sewage pipe will produce a lot of stains after long-term use, and the stains will gradually adhere to the pipe wall, causing the stains to emit unpleasant gas. Causes the gas to flow into the air through the nozzle, making the user feel nauseous, reducing the comfort of the shower, and the odor may also spread from the shower to other livin...

AI Technical Summary

Problems solved by technology

[0003] Most of the current floor drains are straight through the mouth of the pipe, and the sewage pipe will produce a lot of stains after being used for a long time, and the stains will gradually adhere to the pipe wall, causing the stains to emit an unpleasant gas. Causes the gas to flow into the air through the nozzle, making the user feel sick, reducing the comfort of the shower, and the odor may also spread from the shower to other living areas, making people feel uncomfortable and reducing the comfort of life. It is seriously affected, and in the process of bathing, hair often falls off and flows into the sewage pipe together with the water flow, causing pipe blockage and water siltation, affecting the use
