Description

The kitchen exhaust stack is prevented the taint of odour check valve

The utility model relates to the device for exhausting oily smoke that uses in a kind of kitchen.

At present, the device for exhausting oily smoke that people use in the kitchen is blade type or curtain formula exhaust structure, exist poorly sealed, can not be windproof, rainproof, anti-taint of odour, and complex structure, working life weak point, inconvenient maintenance, problem such as can not be complementary with the oil-smoke expulsion pipe of last forward galley employing.

The purpose of this utility model provides the kitchen exhaust stack check valve of windproof, rainproof, the anti-taint of odour of a kind of energy.

The purpose of this utility model is achieved in that by the range hood hose coupling, Returnning spring, slide bar, windshield, compositions such as swab case, one spill circular groove is arranged on the range hood hose coupling, the check plate covers on the interior edge of spill circular groove, there is a slide bar at check plate center, slide bar inserts and is fixed in the spring sealed pipe in range hood hose coupling center portion, one Returnning spring is arranged in the spring sealed pipe, make the check plate rely on the effect of Returnning spring to automatically reset, windshield and range hood hose coupling are threaded to one, one oil receiving hole is arranged on the windshield, oil receiving hole connects a swab case, and windshield has rubber gasket on the border.

Advantage of the present utility model: compare with traditional similar products, it is tighter to have a sealing, and advantages such as more convenient are installed.Using in the kitchen, clean attractive in appearancely, is the auxiliary equipment of the oil-smoke expulsion pipe that vigorously promotes the use of nation-building portion and each province and city construction system.The hygienic conditions in kitchen have fundamentally been solved, perfect oil-smoke expulsion pipe system.Use building in the dwelling house, also can improve the performance of original cooking-fume discharging system, make outside the kitchen facade unified neat, create good external environment condition.

Below in conjunction with drawings and Examples the utility model is described.
