The utility model lacks in view of aforementioned techniques, with a kind of simple anti-down cigarette sealed interface technology, solve the anti-down cigarette problem that aforementioned means exists, also solved by oil impregnate cigarette in gap between oil extraction smoke pipe and the flue wall and the problem on the flue wall that is fixed on that smoke-ejecting pipe is firm, also solved because of the oil extraction smoke pipe and inserted problems such as the long smoke evacuation that produces of flue is not smooth.

Summary of the invention

The purpose of this utility model provides a kind of conveniently device, the range hood gas exhaust duct is installed, pipeline and flue wall are combined closely prevent that oil smoke is by permeating in the gap, simultaneously when quitting work, range hood can seal fume pipeline, prevent return of smoke and smell, can rely on the strength of cooking-fume discharging to open the proper functioning that baffle plate does not influence range hood during smoke evacuation.

The anti-down cigarette sealed interface of range hood oil extraction smoke pipe, being installed in flue reserves between exhaust port and the range hood oil extraction smoke pipe, constitute by interface overcoat and interface inner soft bushing two-part, it is characterized in that, the interface overcoat is a cylindrical shape, there is the interface fixed plate of an annular at the middle part, interface overcoat one end stretches in the flue gas hole, the other end is connected with the oil extraction smoke pipe, the interface fixed plate is close to and is fixed on the flue outer wall, and the interface inner soft bushing is a cylindrical shape, and an end is clamped between interface overcoat and the flue gas hole wall, the other end is turned round to turning up and is petal-shaped, and left-hand thread is on the inwall in flue gas hole.

Interface outer casing inner wall both sides are the plane, be heavy section, be fixed with two little axles in the position, middle and upper part of heavy section, in the interface overcoat baffle plate is installed, the baffle plate profile is consistent with the interior cross section of interface overcoat, and there are two axis holes the plate washer middle and upper part, matches with little axle on the interface outer casing inner wall, plate washer has the baffle plate brake bars of a projection by flue one side above the interface outer casing inner wall.

Advantage of the present utility model is:

1, cost of production is low, and volume is little, needn't electricity consumption, do not need management yet, and be convenient to install, can be used for transformation to mounted old-fashioned range hood.

2, can prevent return of smoke and smell, reduce the pollution of oil smoke Kitchen hygiene.

3, oil-smoke expulsion pipe firmly can be fixed on the flue wall closely, prevent to insert the problem of not smooth problem of the long smoke evacuation that produces of flue and gap infiltration oil smoke effectively because of the oil extraction smoke pipe
