Abstract

The utility model discloses a shaftless magnetic suspension type deodorization floor drain. According to the technical scheme, the non-shaft magnetic suspension filter element comprises a mounting seat, an annular valve element arranged in the mounting seat and a filter screen arranged on the annular valve element, and a non-shaft magnetic suspension frame is arranged at the bottom of the annular valve element; the shaftless magnetic suspension frame comprises an annular installation frame, at least three supporting frames arranged at the bottom of the annular installation frame in a circumferential arrangement mode and shaftless valve clacks arranged in the supporting frames, a first magnetic column is arranged in the center of the filter screen, and a second magnetic column attracted with the first magnetic column is arranged in the center of each shaftless valve clack. The valve has the advantages that the valve clack is of a shaftless structure, and the situation that the valve clack cannot be opened or reset due to the fact that the guide shaft is clamped can be prevented.

Description

Technical Field

[0001] The utility model belongs to the field of bathrooms, and in particular relates to an anti-odor floor drain. Background Art

[0002] The traditional odor-proof floor drain is the interface between the floor surface (mainly the bathroom) and the drainage pipe in the house. A water seal is designed under the filter. The water stored inside can isolate the odor in the pipe, which has an odor-proof effect. However, the disadvantages of the odor-proof floor drain with a water seal structure are: the drainage volume is small, and the water seal is also prone to breed bacteria and mosquito eggs. Therefore, a magnetic levitation odor-proof floor drain has appeared on the market. It uses two magnets that attract each other to control the closing of the valve disc. When the water pressure is high, the valve disc gets rid of the suction and opens the drainage port. However, the magnetic levitation odor-proof floor drain also has the disadvantage that the guide rod at the bottom of the valve disc and the guide rod seat will get stuck due to the increase of friction (caused by dirt on the surface of the guide rod and the guide rod seat or caused by the guide rod being tilted and stuck), resulting in the valve disc being unable to be opened or reset.
