Abstract

The utility model discloses a flue check valve. The flue check valve comprises a face plate, a flue pipe and a check plate. A connecting plate is arranged on the back end surface of the flue pipe. The check plate is connected with the connecting plate through a hinging shaft. The check plate and the back end surface of the flue pipe are matched in shape. The back end surface of the flue pipe is inclined. An oil leakage hole is formed in the lower side of the back end surface of the flue pipe. An oil storage groove is connected with the lower portion of the oil leakage hole. Two rows of I-shaped sliding blocks corresponding to I-shaped sliding chutes in the oil storage groove are arranged on the flue pipe. By the adoption of the structure, due to the fact that the oil leakage hole is formed in the lower end of the flue pipe, waste oil can enter the oil storage groove through the oil leakage hole, oil is not prone to massively accumulating in the flue pipe, not only is seal performance of the check valve not influenced, but also pests such as cockroaches are not attracted.

Description

Check valve for flue

Technical field

The utility model relates to a kind of check valve, especially a kind of family kitchen check valve for flue.

Background technique

In the prior art, the kitchen fume machine is discharged outdoor by check valve for flue after absorbing oil smoke, oil smoke is in passing through the process of check valve for flue, tend to be built-up on the flue tube wall, slowly gather the back in the flue lower end from check valve for flue exhaust outlet drippage, the flue lower end is gathered for a long time a large amount of waste oil, has both influenced the sealing of check valve, attract insects such as cockroach again easily, extremely unhygienic.

The model utility content

The purpose of this utility model is to provide a kind of check valve for flue, but the waste oil in the effective collection flue makes to be not easy to assemble waste oil in the flue.

For achieving the above object, the technical solution of the utility model is: check valve for flue, comprise panel, flue tube, the flue tube ear end face is provided with connecting plate, and by the retaining board that hinging shaft is connected with connecting plate, retaining board and flue tube ear end face shape are coincide, the flue tube ear end face tilts, flue tube ear end face downside is provided with an oil leaking hole, is connected to oil storage tank under the oil leaking hole, and flue tube is provided with the corresponding worker's type of worker's type chute slide block on two rows and the oil storage tank.

The beneficial effects of the utility model are: after adopting the utility model structure, owing to be provided with oil leaking hole in the flue tube lower end, waste oil can enter in the oil storage tank by oil leaking hole, makes flue tube be difficult for a large amount of long-pending oil, neither can influence the sealing of check valve, can not attract insects such as cockroach again.
