Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
As shown in Figs. 1-5, a kind of low noise air supply device being convenient to clean, including motor 1,1 left end of motor are fixed
It is connected with fan shroud 2, air-supply connecting plate 4, described 4 four jiaos of companies of being provided with of air-supply connecting plate are fixedly connected on the fan shroud 2
Threaded hole 5 is connect, facilitates connection air supply duct, is equipped with rotating device 3 in the fan shroud 2, and the rotating device 3 is fixedly connected
In the output end of motor 1,2 side of fan shroud is equipped with through-hole, and dust filter screen 8 is connected in through-hole, and through-hole outside is solid
Surely it is connected with card slot 7, is equipped with clip 6 above the card slot 7, the fan shroud 2 is by aluminium alloy layer 9, cellular board 10, silencing cotton layer
11 constitute, and the silencing cotton layer 11 be arranged between aluminium alloy layer 9 and cellular board 10, the rotating device 3 by casing 12, from
Heart flabellum 13 is constituted, and centrifugal flabellum 13 is designed by special centrifugal multiblade formula, can quietly be operated not after dynamic balance calibration
Vibration, due to being full of many cotton-wools in many working environment air, so centrifugation blade 13 and dust filter screen 8 are by especially setting
Meter, fan blade shape are not easy card cotton-wool, and dust filter screen 8, which becomes to pull up, carrys out clean mode, are greatly reduced in this way because of dust
The situation that strainer 8 or 13 card cotton-wool of centrifugation blade excessively cause air inadequate, the centrifugal flabellum 13 are uniformly fixedly connected on set
12 outside of pipe drives 13 high-speed rotation of centrifugal flabellum to generate air-flow and is sent to air outlet, by cellular board 10 and disappears using motor 1
Sound cotton layer 11 can effectively reduce the noise generated in 13 rotation process of centrifugal flabellum, be fixedly connected in the dust filter screen 8
Fixture block 14, for being coupled dust filter screen 8 with clip 6.
More specifically, the rotating device 3 is fixedly connected with the output end of motor 1,6 left end of clip by casing 12
It is connected on fan shroud 2 by articulate, fan shroud 2, the width of the fixture block 14 is bolted in 6 right end of clip
Less than the length of clip 6, clip 6 can be opened by bolt when dust is excessive in dust filter screen 8, by dust filter screen 8 from card
