Electric fan with air filter
The present invention relates to a kind of electric fan, more particularly relate to a kind of electric fan that can blow out fresh air.
The common electrical fan does not generally have the air-filtering of making, and blows out the function of fresh air, and this requires more and more higher household, the office space of quality for the modern life, can't but be a kind of defective.
The purpose of this invention is to provide a kind of inhaled air can the filtration, blow out fresh air, strengthen health, improve the quality of people's modern life.
For reaching this purpose, the present invention adopts following technological scheme: at the air intake one side configuration air filter of common electrical fan, this air is crossed device and is made of web plate, pre-filtering layer, filter screen seat, filter screen and filter cloth, web plate and filter screen seat are inlaid on the fan bonnet, pre-filtering layer is set in the web plate, filter screen and filter cloth are set in the filter screen seat.
Described pre-filtering layer is that sponge is made, and filter screen is the active carbon adsorption filter screen.
Described filter cloth replaces tensioning by the pillar on the filter screen seat.
Described electric fan with air filter also comprises synchronous machine, land and inducer, and inducer is contained in the axle head of synchronous machine, and the front of flabellum is directly driven by synchronous machine, and land couples together protecgulum and synchronous machine.
The electric fan of structure like this, adopt three-stage filtration, its inhaled air is through pre-filtering layer pre-flock, but airborne dust of elimination and suspending sundries, again through the smart filter of active carbon adsorption filter screen, can further remove airborne impurity and peculiar smell, also pass through the filter cloth that the flame-retardant fiber material is made, then air is purer, pure and fresh; Spill disinfector respectively on pre-filtering layer, filter screen and filter cloth, then inhaled air can be through sterilization, sterilization.According to test, use the electric fan of the present invention can be to 20m in 15 minutes
2The room ventilate once.Inducer directly drives with small synchronous motor, and it is steadily quiet to turn round, and the present invention also is provided with the ultra-low speed breeze-driven shelves, and wind-force is softer comfortable, and blowing use continuously has the natural-wind-imitating effect when being particularly suitable for sleeping.
Below in conjunction with drawings and Examples in detail the present invention is described in detail.
Fig. 1 is a structural representation of the present invention (work is analysed and observe);
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is the left view of Fig. 1.
Accompanying drawing has been described an embodiment.In Fig. 1-Fig. 3:
1. flabellum 2. inducers 3. lands 4. filter screen seats 5. pre-filtering layer 6. web plates 7. filter screens 8. synchronous machines 9. filter clothes 10. fan electromotors 11. bonnets 12. protecgulums 13. operation panels 14. pillars
As seen from the figure, present embodiment comprises common electrical fan and air filter, the common electrical fan is made of flabellum 1, fan electromotor 10, protecgulum 12, bonnet 11, operation panel 13, air filter is located at air intake one side, this air filter is made of web plate 6, pre-filtering layer 5, filter screen seat 4, filter screen 7 and filter cloth 9, web plate 6 and filter screen seat 4 are inlaid on the bonnet 11, and pre-filtering layer 5 is set in the web plate 6, and the pre-filtering layer 5 of present embodiment is made for sponge.Filter screen 7 and filter cloth 9 are set in the filter screen seat 4, and filter cloth 9 is by the 14 alternately tensionings of the pillar on the filter screen 4, and the filter screen 7 of present embodiment is the active carbon adsorption filter screen.Present embodiment also comprises synchronous machine 8, land 3 and inducer 2, and inducer 2 is contained in the axle head of synchronous machine 8, and the front of flabellum 1 is directly driven by synchronous machine 8, and land 3 couples together protecgulum 12 and synchronous machine 8.The suction air of present embodiment is removed airborne floating dust impurity and peculiar smell totally through three-stage filtration, can be with 20m in 15 minutes
2Indoor air change once.Present embodiment also is provided with the ultra-low speed breeze-driven shelves, and wind-force is softer comfortable, blowing use continuously when being particularly suitable for sleeping.
