A sewage floor drain with anti-odor air flowing out and automatically opened and closed 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 that prevents odor-resistant airflow and automatically opens and closes by buoyancy.Background technique[0002]The floor drain is a kind of sewage equipment that facilitates the discharge of domestic sewage. Most of it is installed in the shower room to facilitate the discharge of the sewage generated in the bath into the sewage pipe, so that the sewage flows to a fixed location and is concentrated for later treatment.[0003]The current floor drains are mostly straight through the pipe orifices, and the sewage pipes will produce a lot of stains after long-term use. The stains gradually adhere to the pipe walls, causing the stains to emit unpleasant gases. Moreover, the current floor drains do not have a device to close the nozzles. Causes the gas to flow into the air through the nozzle, making the user feel nauseous, reducing the comfort of the shower room, and the odor m...

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
