Description

Floor drain assembly

Technical Field

The utility model belongs to the technical field of hydrophone down, a floor drain subassembly is related to.

Background

The floor drain is a drainage device for connecting the ground with a drainage pipeline system, plays roles of draining sewage, preventing returning odor and the like, directly influences the quality of indoor air due to the good and bad performance of the floor drain, and plays an important role in controlling peculiar smell in a bathroom.

The existing floor drain generally comprises a shell, wherein a drainage channel is arranged in the shell, the drainage channel connects the ground with a drainage pipeline system, a water sealing plate and a spring are arranged on the drainage channel, when the floor drain drains water, water flow impacts the water sealing plate to enable the water sealing plate to move, and the spring is stressed and deformed at the moment, so that the water sealing plate opens the drainage channel to discharge sewage on the ground to the drainage pipeline system; when the drainage of the floor drain is stopped, the water sealing plate resets under the elastic force of the spring, and the water sealing plate seals the drainage channel to prevent odor in the drainage pipeline system from flowing back to the indoor space, so that the deodorization effect is achieved.

However, after the floor drain is used for a long time, the spring is easy to age, the elasticity of the spring is reduced after the spring ages, and the spring is not easy to deform, so that the situation that the movement amplitude of the water sealing plate is small when the floor drain drains water or the water sealing plate cannot completely seal the water drainage channel when the floor drain stops draining water can be caused, and the drainage of the floor drain is slow or the deodorization effect of the floor drain is poor; the spring is arranged in the drainage channel of the floor drain, the floor drain is generally embedded in the ground, hands or tools generally cannot reach the spring, so that the spring cannot be independently replaced, the floor drain can only be replaced wholly, the floor drain needs to be pried out from the ground, the operation is very troublesome, and tiles around the floor drain are easy to damage.

In addition, the size of above-mentioned floor drain is fixed, can't adapt to different interfaces.
