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 indoor-outdoor air exchange
A spacelike controlled atmosphere electricity-saving appliance.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 house
Front yard and public place.
Change the scavenging way of fan and have discharge formula, suction-type by formula three kinds.Discharge formula
Enter air from natural inflow mouth, discharge air pollution by changing fan；Suction-type passes through
Change fan and suck fresh air, discharge air pollution from natural air vent；And with formula be inhale
Gas and aerofluxus are completed by changing fan.Driven fan blade to rotate by motor and drive air-flow,
Make the spacelike controlled atmosphere electricity-saving appliance that indoor-outdoor air exchanges.Also known as ventilating fan.The mesh of ventilation
Seek to remove indoor air pollution, regulation temperature, humidity and sensory effect.Change
Fan is widely used in family and public place.
It is most popular to change fan, mainly by motor, fan that venetian blind type changes fan
The subsidiary component compositions such as leaf, wind frame, panel, shutter and special pullswitch.
Motor typically uses single-phase capacitor operation asyn. motor.Changing below 150mm specification
Fan is also adopted by shadedpole motor.Flabellum typically uses ABS, AS injection molding,
Lightweight and intensity is high.Wind frame is generally made with sheet metal punching press and spot welding, also has employing
Injection molding.Panel uses injection molding.Shutter generally uses sheet metal
Or tinplate punch forming.Existing change fan in scavenging period to the dust mistake in air
Filter weak effect.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of
Change fan.
This utility model is to be achieved through the following technical solutions:
One changes fan, including body fuselage, both sides, described body fuselage upper end is arranged
Having several connecting holes, both sides, lower end are provided with the fixing card of L-shaped, described L-shaped is fixed
Card is connected with outer baffle, and described body fuselage is internally provided with link, described connection
Frame center is provided with motor, and described motor output end is connected with air draft flabellum, institute
Stating and be provided with some groups of spacing flanges on body fuselage sidewall, described spacing flange longitudinally cuts
Face is triangular in shape, described each group of spacing flange is respectively arranged with the first drainage screen,
Two drainage screens.
As optimal technical scheme of the present utility model, described spacing flange and body fuselage
Between be formed in one.
As optimal technical scheme of the present utility model, described first drainage screen, the second mistake
Filter screen is V-shaped, and wedge angle direction is towards air intake direction.
As optimal technical scheme of the present utility model, the filtration essence of described first drainage screen
Degree is less than the filtering accuracy of the second drainage screen.
Compared with prior art, the beneficial effects of the utility model are: this utility model
Simple in construction, by arranging the first drainage screen, the second drainage screen, the most in use,
Driven by motor air draft flabellum high speed rotating produces negative pressure gravitation, and now dust filters first
Net, the second drainage screen effect under can realize filtering, the effective powder crossed in air filtering
Dirt, it is simple to follow-up dust cleaning, meets the demand of people.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer,
Below in conjunction with drawings and Examples, this utility model is further elaborated.Should
Work as understanding, specific embodiment described herein only in order to explain this utility model, and
It is not used in restriction this utility model.
Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.
One changes fan, including body fuselage 1, on both sides, described body fuselage 1 upper end
It is provided with several connecting holes 101, both sides, lower end is provided with L-shaped and fixes card 102, institute
Stating the fixing card 102 of L-shaped to be connected with outer baffle 2, described body fuselage 1 is internal to be arranged
Link 3, described link 3 center is had to be provided with motor 4, described motor 4
Outfan is connected with air draft flabellum 5, described body fuselage 1 sidewall is provided with some
Organize spacing flange 103, be one between wherein said spacing flange 103 and body fuselage 1
Body formed, so can realize the installation of first drainage screen the 6, second drainage screen 7.
Described spacing flange 103 longitudinal cross-section is triangular in shape, described each group of spacing flange 103
On be respectively arranged with first drainage screen the 6, second drainage screen 7, wherein said first drainage screen
6, the second drainage screen 7 is V-shaped, and wedge angle direction is towards air intake direction, the most permissible
Avoiding blockage phenomenon, the filtering accuracy of described first drainage screen 6 is less than the second mistake
The filtering accuracy of filter screen 7.The most in use, motor 4 drives air draft flabellum 5 at a high speed
Rotating and produce negative pressure gravitation, now dust is at first drainage screen the 6, second drainage screen 7
