Abstract

The invention relates to a double odor-resistant floor drain device. The floor drain device comprises water leakage grid bars, an outer cavity, an inner cavity and an odor-resistant inner core, wherein the water leakage grid bars are movably connected to the top of the outer cavity, the inner cavity is fixed in the outer cavity, and the odor-resistant inner core is arranged at the bottom of the inner cavity; holes are formed in the side wall of the inner cavity, a floating plate is arranged in the inner cavity, and the odor-resistant inner core comprises an inner cylinder, outer cylinders, steel balls, supports, springs, water nozzles and a rotary closer; and the supports are arranged on the outer sides of the inner cylinder, the steel balls are arranged on the supports, the outer cylinders are nested on the inner cylinder through the steel balls, water permeation holes are formed in the side walls of the bottom of the inner cylinder, the water nozzles are distributed on the two sidesof the outer cylinders, and water outlets of the water nozzles on the two sides are opposite in direction. The floating plate is matched with the rotary closer, and the floating plate blocks water drainage openings of a floor drain, so that first isolation protection is achieved; and when the rotary closer is in a closed state when no water exists, second isolation protection is achieved, so thatodor and microorganisms in a drainage pipeline are effectively prevented from entering a clean area, the cost is low, the operation is convenient, and wide application and popularization are facilitated.

Description

technical field

[0001] The invention relates to a double anti-odor floor drain device, which belongs to the technical field of floor drains. Background technique

[0002] The floor drain is an important interface connecting the drainage system with the indoor floor. As an important part of the drainage system in the house, its performance directly affects the quality of the indoor air. It is very important for the odor control in the bathroom. There are many types of floor drains, mainly eccentric Block type bottom flap floor drains, spring type floor drains, magnet type floor drains, gravity type floor drains, silicone type floor drains, etc., but some existing floor drains are not well sealed or the shaft is prone to failure. Among them, the pure gravity type is not well sealed because the gravity is too small. However, those with a rotating shaft will fail due to foreign matter entering the joint of the rotating shaft after a long time. There is a lack of a floor drain th...
