Description

technical field [0001] The invention belongs to the technical field of floor drains, in particular to an anti-backwater floor drain. Background technique [0002] The floor drain is a drainage device that connects the ground to the drainage pipeline system. It removes ground water, dust, fibrous matter, hair, and easy sediments. Most of the existing floor drains adopt the water-tight and odor-proof floor drains of the water return overflow structure. And the water-sealed floor drain will lose the function of sealing and deodorizing because the water level is too low or dries up after a period of time without water, and the floor drain will lose the function of sealing and deodorizing, thereby requiring frequent water replenishment and deodorizing, which brings great inconvenience to users. Contents of the invention [0003] The invention aims at the deficiencies of the prior art and provides an anti-return water floor drain, which can effectively prevent the return of wat...
