Odor-resistant floor drain with self-cleaning capability

Abstract

The invention relates to the field of floor drains, in particular to an odor-resistant floor drain with a self-cleaning capability. The floor drain comprises a floor drain shell, a floor drain cover,a connecting column, a buoyancy ascending device, a telescopic device, a fixing frame, water outlet cylinders, and second floating plates; a first circular through hole is formed in the bottom wall ofthe floor drain shell; the floor drain cover is mounted at an opening in the upper end of the floor drain shell and is provided with a water inlet; the fixing frame is fixedly arranged inside the floor drain shell and provided with a barrel-shaped space with a downward opening; the buoyancy ascending device comprises a first floating plate, connecting rods, and buoyancy ring plugs; the first floating plate is arranged in the floor drain shell in an up-down sliding mode; the connecting rods are vertically arranged; the buoyancy ring plugs are arranged at the lower ends of the connecting rods;the water outlet cylinders can be installed at the first circular through hole; and the second floating plate is horizontally arranged and located in the fixing frame. According to the odor-resistantfloor drain with the self-cleaning capability, the telescopic device is configured to convert ascending motion and descending motion of the second floating plate into descending motion and ascending motion of the water outlet cylinders, so that the problem that impurities in an existing floor drain are difficult to clean is solved.

Description

technical field [0001] The invention relates to the field of floor drains, in particular to an odor-proof floor drain with self-cleaning capability. Background technique [0002] The floor drain is an important interface connecting the drainage pipe system and the indoor floor. As an important part of the drainage system in the residence, its performance directly affects the quality of the indoor air, and is very important for the odor control in the bathroom. The floor drain should have two basic functions: first, to ensure smooth drainage and to quickly remove the accumulated water on the ground; second, to have good sealing performance and to effectively prevent the odor in the sewer from entering the room. The current floor drains usually adopt a water seal structure. Because of the existence of the water seal, the water flow of the floor drain will be more tortuous, the speed of the water will be slow, and there will be impurities deposited at the corners. Over time, it...
