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.
