Summary of the invention:

For overcoming defectives such as the displacement that present floor drain exists is little, deodorization " water seal " is unreliable, the purpose of this utility model is to provide a kind of odour-proof floor drain, it can guarantee that draining is unblocked under the big situation of the water yield, in the time of can being implemented in not draining again, excessive peculiar smell that looses of sewer mouth and insects are intercepted below floor drain, to guarantee the cleaning of indoor environment.

For achieving the above object, the technical solution of the utility model is a kind of odour-proof floor drain, it mainly comprises the floor drain body, wall is shaped on step within it, the bottom is shaped on delivery port, be provided with cover plate at an upper portion thereof, the cover plate end face is shaped on a circle water inlet along circumference, it is characterized in that: on step, be provided with plectane, along the circumferential direction be shaped on a circle leaking hole at plectane end face middle part, and in the plectane centre bore, be fixedly connected with a dirt proof sleeve, the dirt proof sleeve bottom is connected with a dismountable axle sleeve, and cross-under has a mobilizable central axis in axle sleeve hole, and central axis top is socketed with a cylindroid helical-coil compression spring, the cross-under of central axis bottom has a little axle sleeve, little axle sleeve external diameter is uniform to be fixed with four little fins, and the winglet sheet other end is fixedly connected on barrel bore, is fixed with four big fins in that cylinder upper end external diameter is uniform, the big fin other end is fixedly connected on the Circular Plate internal diameter, in the stomidium alignment pin is housed under central axis.

The beneficial effects of the utility model are: do not need external energies such as electricity, heat, only by by draining self kinetic energy, both reached the purpose of quick draining, satisfied the effect of automatic shutoff again, realized preventing under the situations such as tap water pipe line explosion, big discharge capacity flowing water overflows out of control, prevents the drainage pipeline peculiar smell many anti-effects such as loose, the insects anti-channeling is indoor of overflowing.
