Buoyancy type automatic sealing deodorization floor drain

Abstract

The invention discloses a buoyancy type automatic sealing deodorization floor drain. The buoyancy type automatic sealing deodorization floor drain comprises a floor drain body and an opening and closing assembly, wherein the floor drain body is hollow to form a water drainage channel, and the opening and closing assembly can automatically open and close the water drainage channel through water buoyancy. The opening and closing assembly comprises a valve seat arranged in the floor drain body and a floating part capable of being matched with the valve seat in a vertically-floating mode to open and close the water drainage channel. When water flows into the water drainage channel in the floor drain body, the floating part can move upwards to be separated from the valve seat under the effect of the water buoyancy, the water drainage channel is opened to drain sewage, after the sewage is drained, no water exists in the water drainage channel, the floating part moves downwards to make contact with the valve seat under the effect of weight to achieve sealing fit, the water drainage channel is closed accordingly, and then the situation that odor in the water drainage channel escapes out of the floor drain body to contaminate indoor sanitation is avoided. The buoyancy type automatic sealing deodorization floor drain is good in sealing effect, and can effectively prevent insects and odorization, compared with a spring-structure automatic opening and closing device in an existing floor drain, the structure is simple, the service life is long, and the floor drain is convenient to install and clean.

Description

technical field [0001] The invention relates to the field of indoor drainage systems, in particular to a buoyancy type automatic sealing and deodorant floor drain. Background technique [0002] Floor drains are designed and installed on the ground in kitchens, bathrooms, and balconies of buildings to discharge sewage. The performance of the floor drain directly affects the quality of the indoor air, and is very important for indoor odor control. In order to achieve the purpose of deodorizing and preventing insects, a sealing device is arranged in the existing floor drain, and the sealing device seals the floor drain after the drainage of the floor drain is completed, so as to achieve the purposes of deodorizing and preventing insects. However, most of the sealing devices in the existing floor drains are one-way valve structures, which achieve the purpose of automatic opening and sealing through the effect of water flow pressure and spring automatic rebound, but this sealing...

Problems solved by technology

However, most of the sealing devices in the existing floor drains are one-way valve structures, which achieve the purpose of automatic opening and sealing through the effect of water flow pressure and spring automatic rebound, but this sealing device has certain limitations, and its sealing performance is not good. , or it is easily damaged during long-term use, the service life is not long, and it needs to be replaced frequently, and the installation structure of the spring needs to occupy a large space, and the installation is complicated, and it is very inconvenient to clean it
