Description
The utility model relates to a kind of building cigarette air channel air-valve.
At present, the flue of residential housing is little to the pump drainage power of indoor air, and cigarette, taint of odour phenomenon often take place.Existing a kind of check flue interface comprises housing, intake grill, exhaust outlet, check blinds and catchment cup, and housing is positioned at indoor air inlet one side, cigarette air channel connecting plate is connected with the cigarette air channel, exhaust outlet is positioned at the cigarette air channel, and housing takies the interior space, needs frequent disassembly, cleaning; Exhaust outlet smoke evacuation resistance is big, requires further improvement.
The purpose of this utility model provides a kind of improved cigarette air channel one-way valve, reduces the resistance of discharging fume, and the smoke evacuation draft is strengthened, and prevents down that cigarette, taint of odour take place, and does not take the interior space, does not need disassembly, cleaning.
Cigarette of the present utility model air channel one-way valve, comprise housing, flue connecting plate, intake grill, exhaust outlet, check blinds and catchment cup, it is characterized in that: housing is positioned at the cigarette air channel, exhaust outlet is positioned at the housing upper end, intake grill is opened on the flue connecting plate, the flue connecting plate closely is connected with flue, and slideway type check blinds inserts in the housing.Above-mentioned slideway type check valve has together or twice.
When the utility model is installed, cigarette air channel single current valve housing is installed in flue, and the flue connecting plate closely is connected with flue exit, and intake grill links to each other with the range hood pipeline, exhaust outlet is positioned at flue, reloads after taking catchment cup after a period of time, pulling out the non-return blinds cleaning of slideway type.Oil smoke in the kitchen and smell are drained into flue through cigarette air channel one-way valve, and non-return blinds is only permitted gas unidirectional and flowed out, mustn't the gas inlet chamber in, prevented that cigarette and taint of odour take place.
Advantage of the present utility model: cigarette air channel one-way valve housing parts is packed in the flue, does not take the interior space, does not need disassembly, cleaning, check is good, encapsulation is good, avoided the worry of indoor smoke-returning, taint of odour, and exhaust outlet is positioned at the housing upper end, make housing become the air-out runner, windage is little, and makes the inner negative pressure that produces in cigarette air channel, and the smoke evacuation draft is big, improve habitation environment quality, be applicable to the house kitchen smoke evacuation.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is the utility model embodiment one a schematic representation, and twice check blinds is arranged, and intake grill is circular.
Fig. 2 is the utility model embodiment two a schematic representation, and the check blinds is arranged one, and intake grill is square, can be connected with range hood pipeline, exhaust duct or toilet exhaust port.
As shown in the figure, this cigarette air channel one-way valve, comprise housing 1, flue connecting plate 2, intake grill 5, exhaust outlet 4, the non-return blinds 3 of slideway type and catchment cup 6, it is characterized in that housing is positioned at the cigarette air channel, exhaust outlet is positioned at the housing upper end, intake grill is opened on the flue connecting plate, and the flue connecting plate closely is connected with flue, and the non-return blinds of slideway type is in housing between intake grill and the exhaust outlet.Can establish one or twice.Embodiment one is applicable to circular flue; Embodiment two is applicable to square flue.
Claims (3)
1, a kind of cigarette air channel one-way valve, comprise housing, flue connecting plate, intake grill, exhaust outlet, check blinds and catchment cup, it is characterized in that: housing is positioned at inboard, cigarette air channel, exhaust outlet is positioned at the housing upper end, intake grill is opened on the flue connecting plate, the flue connecting plate closely is connected with flue, and slideway type check blinds is positioned at housing.
2, double backstop flue interface according to claim 1 is characterized in that: the non-return blinds of described slideway type has together.
