Odor-resistant floor drain

Abstract

The invention relates to the field of floor drains, and particularly relates to an odor-resistant floor drain. The odor-resistant floor drain is characterized by comprising a surface cover, a filter screen, a floor drain shell and an odor-resistant core, wherein a drainage ligament is arranged on the periphery of a sealing piece on a turning plate, and a V / U-shaped groove is formed between the drainage ligament and a sealing body. When water flows from top to bottom and the water flow is small, the drainage ligament contracts inwards to form a drainage gap, at the moment, the overturning and opening amplitude is small, and the abrasion of parts is reduced; when water flows from top to bottom and the water flow is large, the drainage ligament contracts inwards, the turning plate is opened,and the drainage speed is high; when water overflows from bottom to top, water pressure is formed in the V / U-shaped groove, pressure is formed on the drainage ligament, the drainage ligament is tightly attached to the inner wall of a core shell, and the sealing and odor-resistant effects are achieved; and even if the reset force is weakened, sealing and odor resistance can be achieved through thefriction force between the drainage ligament and the inner wall of the core shell as long as the turning plate is embedded into the core shell under the action of the overflow water flow force.

Description

technical field [0001] The invention relates to the field of floor drains, in particular to an anti-odor floor drain. Background technique [0002] The floor drain is an important interface connecting the drainage system with the indoor ground. It is installed on the ground of various places such as kitchens, bathrooms and balconies. However, as the core component of the floor drain, the floor drain core, the deodorization and anti-overflow functions of the floor drain core directly affect the quality of the indoor air. Most of the floor drain cores on the market use magnets and springs to achieve end face sealing. When the magnets and springs are used repeatedly, the magnetic force and elastic force become weaker, due to insufficient bonding pressure between the flap and the floor drain core, when the water overflows Insufficient sealing of the end face caused water and odor from the downpipe to overflow into the room. In view of this, this case arose. Contents of the in...

However, as the core component of the floor drain, the floor drain core, the anti-odor and anti-overflow functions of the floor drain core directly affect the quality of indoor air.

Most of the floor drain cores on the market use magnets and springs to achieve end face sealing. When the magnets and springs are used repeatedly, the magnetic force and elastic force become weaker, due to insufficient bonding pressure between the flap and the floor drain core, when the water overflows Insufficient sealing of the end face caused water and odor from the downpipe to overflow into the room.
