Abstract
The utility model relates to a device for preventing counter current of air, and is used for preventing indoor air pollution. The device for preventing counter current of air comprises a middle baffle, a movable baffle, an air inlet and an air outlet, wherein the middle baffle is arranged in the middle of the inside of a casing; the top end of the middle baffle is parallel to the top part of the casing; a gap is formed between the bottom of the middle baffle and the bottom of the casing; the air inlet is formed in the circular cylindrical surface on the left side of the casing and is communicated with the interior of the casing; the air outlet is formed in the right side surface of the casing and is also communicated with the interior of the casing; the position of the air outlet is lower than the position of the air inlet; the movable baffle perpendicular and parallel to the air inlet is arranged at the air inlet end of the casing; the top end of the movable baffle is hinged to the top end of the air inlet. The device for preventing counter current of air has the advantages of simple structure and convenience in manufacturing and maintenance, and can effectively prevent polluted air in the air outlets and drainages in places with high hygiene requirement from reflowing, so that one-way circulation of the indoor air is formed, and the unclean outer air is prevented from polluting the indoor air.
Description
Technical field
The utility model relates to air partition device, specifically indoor air one-way flow device.
Background technique
In the places such as a lot of working environments, living environment as: the ventilated port such as the relief opening in place, washbasin, sewerage is all high atmospheric pollution source, the place channel of above hygienic requirements between hospital operating room, intensive care unit, isolation ward, pharmaceutical factory laboratory, food sanitation etc., require and prevent outside contamination in order to improve environmental hygiene, the crime prevention device of above various channels is installed and is just seemed necessary.
Model utility content
The purpose of this utility model is to provide and prevents air inversion device, it prevents the contaminated air adverse current of relief opening, sewerage in the high place of hygienic requirements effectively, make indoor air form one-way circulation, thereby solution by no means health external environment air indoor air is polluted.
Technical solution of the present utility model is at shell, sealing gasket, on the basis of lid, plate washer in the middle of being characterized in, movable plate washer, air inlet, air outlet slit, described middle plate washer setting middle in the enclosure, the top of middle plate washer is parallel with the top of shell, between the bottom in its bottom and shell, has gap; Air inlet is arranged on the cylndrical surface in shell left side, and is communicated with in shell; Air outlet slit is arranged on shell right flank, is also communicated with in shell; The position that the position that air outlet slit arranges arranges than air inlet is low; Air inlet end be in the enclosure provided with one with the movable plate washer of air inlet vertical parallel, the top of movable plate washer top and air inlet is hinged.
Working principle of the present utility model is design air entrance, air outlet slit, on air inlet, design sideboard, when indoor air pressure is when outdoor, then air flows to and discharges from air outlet slit from entrance, when indoor air pressure is when outdoor, because sideboard can only unidirectionally be opened, so outdoor air cannot adverse current enter indoor, and by the pollutant such as ponding, rubbish in uncap energy periodic cleaning shell, effectively prevent that insect is derivative, for indoor air clean degree has improved guarantee.
The utility model has the advantages that simple in structure, manufacture and easy to maintenance, can effectively prevent the contaminated air adverse current of relief opening, sewerage in the high place of hygienic requirements, make indoor air form one-way circulation, thereby solution by no means health external environment air indoor air is polluted.
