Description

Floor drain

Technical Field

The application relates to the field of drainage, in particular to a floor drain.

Background

The floor drain is an important interface for connecting a drainage pipeline system and the indoor ground, is an important part of a drainage system in a house, has the performance which directly influences the quality of indoor air, and is very important for controlling peculiar smell in a bathroom.

Chinese patent application publication No. CN106894496A discloses a through type float deodorizing floor drain to alleviate the technical problem of bad deodorizing effect of the floor drain in the prior art. It comprises a shell, a cover body and a floater; one end of the shell facing the cover body is opened, and the water outlet is arranged at one end of the shell facing away from the cover body; the floater is arranged in the inner cavity of the shell and is detachably abutted to the water outlet of the shell; the cover body is arranged above the shell and is provided with a water inlet hole communicated with the inner cavity of the shell; the middle part of the cover body is provided with a floater channel for the floater to extend out. The deodorant floor drain of penetrating type float that it provided can effectively solve the deodorant not good technical problem of effect of floor drain.

However, sundries are deposited on the periphery of the sewer pipe of the patent to jack the floater, so that the problem of reverse flow of peculiar smell cannot be solved; and when the floater floats, the applicant finds that the floater can not normally return to the correct position to block the peculiar smell after the launching is finished due to the fact that the gravity center of the floater is not matched with the shape of the shell.

Chinese patent No. CN201785852U discloses an automatically-closed floor drain, which comprises a housing and a top cover, wherein a floating ball is placed in the housing, the top cover covers the housing, and the diameter of the floating ball is larger than that of a water outlet hole at the lower part of the housing. When certain sewage is stored in the shell, the floating ball floats upwards to discharge the sewage from the water outlet, and when no water exists in the shell, the floating ball falls back to the upper opening of the water outlet to seal the upper opening of the water outlet.

For the patent, the applicant finds that the floating ball will float when the backflow gas is slightly larger and cannot block odor, and the floating ball will be sucked and cannot float due to the action of atmospheric pressure when the sewer is slightly larger.

Chinese patent No. CN200982013Y discloses a float-type floor drain, which comprises a casing, an upper cover, and a float sealing cover. The lower end of the shell is provided with a water tank which is matched with the falling float sealing cover. When a large amount of accumulated water enters the abdominal cavity, the float sealing cover is lifted by the water, and the water flows out from the water outlet. After the water flows out, the float sealing cover can automatically fall down and be inserted into the bottom of the water tank, and the effect of complete sealing is achieved.

For this patent, the applicant found during testing, but normal use was compromised when silt, small stones or hair, etc. accumulated at the location where the float seal cover was connected to the sink.

The application publication number is CN 104196112A's chinese patent discloses a floor drain for deodorant and mosquito and fly, including floor drain casing, floor drain lid and drain pipe, still including being used for the closing cap and opening the orificial sealing device of this drain pipe water inlet, sealing device is the ring shape body part of cavity that the bell jar of back-off and bell jar bottom outside were inlayed, and the intermediate position is inlayed and is being inserted and sealed the orificial pipe orifice stopper of this drain pipe water inlet on the inner wall at this bell jar bell bottom, and the bottom equidistance of this ring shape body part of cavity has set gradually 4-6 places arc sunken. Dirty gas and even mosquitoes in the drainage pipeline are effectively prevented from entering the room to pollute the indoor air, and meanwhile, when the floor drain drains water again, the water body can conveniently enter the bottom of the hollow circular floating body component, so that the inverted bell-jar covering the drainage pipe opening is floated.

But also when silt, small stones or hair etc. accumulate in the bottom position, normal use is impaired.
