Embodiment
Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is further elaborated.
Embodiment 1
Present embodiments provide a kind of ventilation fan, comprise housing 1, motor 2, flabellum 3 and filter sheet 4; Described housing 1 is hollow shape, and its two ends form intake grill 6 and exhaust outlet 5 respectively, and described motor is arranged in housing 1, and described flabellum 3 is fixed in the rotating shaft of described motor 2, and described filter sheet 4 is arranged in housing 1 near exhaust outlet 5 one end.Motor 2 is energized work, and motor 2 rotating shaft drives flabellum 3 to rotate, and form air flowing, outdoor air can flow into from intake grill 6, when air flows near exhaust outlet 5, cleans, flow out after filtration from exhaust outlet 5 again owing to being provided with filter sheet 4 pairs of air.Be arranged so that entering indoor air is through process filtered air, use of feeling more relieved like this, when mounted, motor 2, near outdoor, can not produce noise to indoor during ventilation fan work.
The present embodiment is preferred, also comprises filter screen 7, and described filter screen 7 is arranged in housing 1 near intake grill one end.The above, when ventilation fan works, outdoor air flows into from intake grill 6, first through filter screen 7, after filter screen 7 pairs of air once filter and are fallen by large particle filtering foreign, again flow near exhaust outlet 5 time, by filter sheet 4 pairs of air carry out second time filtration, after flow to indoor from exhaust outlet 5 again.Such setting improves the filtration treatment degree to air.
The present embodiment is preferred, and also comprise silicon controlled speed regulator, described silicon controlled speed regulator is connected with motor circuit, carries out regulating and controlling to described machine shaft rotating speed.Carry out speed governing adjustment by the rotating shaft rotating speed of described silicon controlled speed regulator to described motor, because described flabellum 3 is fixed in the rotating shaft of described motor 2, the rotating speed of described flabellum 3 also can along with adjusting rotary speed.Arrange client like this can regulate flabellum rotating speed as required, thus the effective flowing size controlling air.
The present embodiment is preferred, and described housing 1 wall offers through hole 10 near intake grill 6 place.When ventilation fan works, due to the effect of wind-force, may when air flows into ventilation fan entrapped moisture, when there is water constituent in ventilation fan, ventilation fan can be flowed out by set through hole 10, improving the running of ventilation fan.
The present embodiment is preferred, and described through hole 10 is opened on the shell body wall between described intake grill 6 and filter screen 7.Arrange the inside that water constituent can be made not contact ventilation fan so just can flow out by by 10, ensure that the parts such as motor are unaffected, and do not affect the air entering indoor.
The present embodiment is preferred, described housing 1 internal surface is circumferentially with the first rubber ring 11 near exhaust outlet 5 one end, described first rubber ring 11 circumference is fitted with described housing 1 inwall, the sidewall of described filter sheet 4 is provided with card 9, described housing 1 inwall is provided with the draw-in groove corresponding with described card 4 near described first rubber ring 11 place, and described filter sheet 4 to be matched with described draw-in groove by described card 9 and is fixed in housing 1.Arrange like this need to filter sheet 4 pull down replace or process time, directly can adjust card 9 and depart from from draw-in groove, thus directly pull down filter sheet 4, when needed, then card 9 is snapped in draw-in groove, filter sheet 4 is fixed in housing 1, this set is simple and convenient, easily dismounting or replacing.
The present embodiment is preferred, and described filter sheet 4 is provided with the second rubber ring 8, described second rubber ring 8 matches with the first rubber ring 11 size, and is fixed on a side of filter sheet 4.When filter sheet 4 is arranged in housing 1; the side and described first rubber ring 11 that are fixed with the second rubber ring 8 are fitted; the first rubber ring 11 and the second rubber ring 8 circumference is made mutually to fit tightly fixing; prevent air from flowing from object inner circumferential position by the second rubber ring 8 with coordinating of the first rubber ring 11 like this; ensure that filter sheet 4 filters all air, filter sheet 4 is played simultaneously and relatively reduce friction thus the effect reaching protection.
The present embodiment is preferred, and also comprise protective housing 13, described protective housing 13 is arranged on housing 1, and near described intake grill 6 one end; Described protective housing 13 comprises framework 14, multiple connecting rod 15 and multiple protection apron 16, described framework 14 is hollow structure, described each connecting rod 15 two ends are hinged on described framework 14, and multiple connecting rod 15 is evenly parallel to each other is arranged on framework 14, described each protection apron 16 is fixed on each described connecting rod 15.When ventilation fan is installed, to be provided with one end of protective housing 13 towards outdoor, when ventilation fan does not work, namely protective housing 13 is now under nature, all protection aprons about 16 are evenly distributed, by the side port closed of framework 14, close, when ventilation fan works by intake grill 6 end, due to air flowing, multiple protection apron 16 hinged with connecting rod 15 rotates under the effect of air wind direction, and protection apron 16 is no longer closed intake grill, thus reaches the effect of air intake ventilation.Such setting is when outdoor is rainy or have water, and ventilation fan, when off position, has the function of rainproof waterproof.
