The utility model discloses when using, the fast rotatory negative pressure gravitation that produces of drive motor drive exhaust fan blade height, the dust can be realized filtering under ARC filtering net's effect this moment, dust among the effectual filtered air, this moment ARC filtering net install under connect buckle's effect and the dismantlement inconvenient, and the sound absorbing layer can reduce the noise that trades the fan during operation, the effect of improvement silence.
Description
Technical field
This utility model relates to technical field of electronic products, particularly relates to one and changes fan.
Background technology
Changing fan is driven fan blade to rotate driving air-flow by motor, makes the spacelike controlled atmosphere joint that indoor-outdoor air exchanges
Electrical equipment.Also known as ventilating fan.The purpose of ventilation seeks to remove indoor air pollution, regulation temperature, humidity and sensory effect.Change
Fan is widely used in family and public place.
Change the scavenging way of fan and have discharge formula, suction-type by formula three kinds.Discharge formula enters from natural inflow mouth
Air, discharges air pollution by changing fan；Suction-type sucks fresh air by changing fan, from natural air vent
Discharge air pollution；And be that air-breathing completes by changing fan with aerofluxus by formula.Driven fan blade to rotate by motor to drive
Air-flow, makes the spacelike controlled atmosphere electricity-saving appliance that indoor-outdoor air exchanges.Also known as ventilating fan.The purpose of ventilation seeks to remove indoor
Air pollution, regulation temperature, humidity and sensory effect.Change fan and be widely used in family and public place.
It is most popular to change fan, mainly by motor, flabellum, wind frame, face that venetian blind type changes fan
The subsidiary component compositions such as plate, shutter and special pullswitch.Motor typically uses single-phase capacitor running asynchronous electric
Machine.The fan that changes below 150mm specification is also adopted by shadedpole motor.Flabellum typically becomes with ABS, AS plastic injection
Type, lightweight and intensity is high.Wind frame is generally made with sheet metal punching press and spot welding, also has employing injection molding.Panel is adopted
Use injection molding.Shutter generally uses sheet metal or tinplate punch forming.The existing fan that changes is when needing dismounting
Install during drainage screen and dismounting inconvenience, and noise is big in running.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one changes fan.
This utility model is to be achieved through the following technical solutions:
One changes fan, and including body fuselage, described body fuselage center is provided with driving motor, described in drive
Dynamic motor output end is connected with air draft flabellum, on described body fuselage side and be positioned on air draft direction and be provided with protective cover,
Be connected for clamping between described protective cover and body fuselage, on described body fuselage side and be positioned on air intake direction be provided with into
Windshield, described air inlet cover is provided with arc drainage screen, and the described upper and lower two ends of arc drainage screen are by connecting buckle and air inlet cover
It is connected, the medial wall of described body fuselage is provided with sound absorbing layer.
As optimal technical scheme of the present utility model, for being articulated and connected between described air inlet cover upper end and body fuselage.
As optimal technical scheme of the present utility model, the arc convex direction of described arc drainage screen is towards air intake side
To.
As optimal technical scheme of the present utility model, described sound absorbing layer is pasted onto on the medial wall of body fuselage, and thick
Degree is 5mm～12mm.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, by the company of setting
Connect buckle, sound absorbing layer, the most in use, drive driven by motor air draft flabellum high speed rotating to produce negative pressure gravitation, now dust
Can realize filtering under the effect of arc drainage screen, the effective dust crossed in air filtering, now arc drainage screen is connecting
Install and dismantle inconvenience under the effect of buckle, and sound absorbing layer can reduce noise when changing fan work, improves quiet effect
Really.
