Floor drain

Abstract

The invention discloses a deodorant and mosquito-proof floor drain. The deodorant and mosquito-proof floor drain comprises a floor drain housing, a floor drain cover and a water drainage pipe, and further comprises a sealing device used for sealing and opening the water inlet of the water drainage pipe; the sealing device comprises an inverted bell jar and a hollow circular ring-shaped floating body component embedded outside the bottom of the bell jar; a pipe opening plug which can be inserted in and seal the water inlet of the water drainage pipe is embedded in the middle on the inner wall at the bottom of the bell jar; 4-6 circular arc-shaped concaves are formed in the bottom of the hollow circular ring-shaped floating body component in sequence at equal intervals. According to the invention, dirty gas even mosquitoes in the water drainage pipe are prevented from entering a room to pollute indoor air; meanwhile, when the floor drain conducts water draining again, the water is convenient to enter the bottom of the hollow circular ring-shaped floating body component, so that the inverted bell jar sealing the water drainage pipe opening is floated; the floor drain is simple in structure, low in manufacturing cost and convenient for popularization and application.

Description

technical field [0001] The invention belongs to a building material product used in conjunction with a sewer pipe, in particular to a floor drain. Background technique [0002] As an important part of the residential drainage system, the floor drain must be sealed while ensuring smooth drainage to prevent the odor in the pipeline from entering the room to pollute the indoor air. Therefore, the performance of the floor drain directly affects the quality of the indoor air. Odor control in the bathroom is very important. Most of the residences now generally use ordinary water-sealed floor drains. Because some rooms with floor drains in the residence do not use water frequently, the water in the floor drain cannot be replenished in time, causing the water level of the water stored in the ordinary water-sealed floor drain to drop or even dry up. It often leads to the loss of the water sealing effect of ordinary water-sealed floor drains, so that the dirty gas in the drainage pip...

Problems solved by technology

Most of the residences now generally use ordinary water-sealed floor drains. Because some rooms with floor drains in the residence do not use water frequently, the water in the floor drains cannot be replenished in time, causing the water level in the ordinary water-sealed floor drains to drop or even dry up. It often leads to the loss of the water sealing function of ordinary water-sealed floor drains, so that the dirty gas in the drainage pipeline and even mosquitoes enter the room and cause pollution to the indoor air. For this reason, people have developed some spring devices or magnetic devices. Anti-odor and anti-pollution floor drain, but this type of floor drain has a complex structure, high production cost, and difficult to use and promote
