Technical field
The utility model ventilation fan apparatus field, specially a kind of ventilation fan controlled by infrared induction.
Background technology
Ventilation fan drives fan blade to rotate certain driving air-flow by motor, a kind of air conditioning electricity for making indoor and outdoor air exchange
Device.Also known as draft fan.The purpose of ventilation seeks to remove indoor foul atmosphere, adjusts temperature, humidity and sensory effect.Ventilation
Fan is widely used in family and public place.The generation of ventilation fan is related with the wet weather of coastal area, is invented in electric fan
The principle that can accelerate gas flowing when Japanese dries with reference to electric fan afterwards, has invented ventilation fan in 1958, and most early in
Japan goes into operation.The product of early stage can only one-way exhaust, therefore also known as exhaust (wind) fan.There is venetian blind type ventilation fan within 1964.
Plastics start largely to use from the eighties in last century, that is, the pipeline fan of today, shutter, show window fan etc..2000 or so
The feature that wind turbine is combined along with the use of central air-conditioning in the developed countries such as North America and West Europe has invented pressure air blowing fan again,
Namely current seperated pipeline fan, direct current pressure fan and round air blower.
Ventilation fan needs artificial control switch in the prior art, and when user of service forgets to close, ventilation fan is run always,
Electric energy is wasted, while being lost larger, the service life has been shortened, in conclusion being now badly in need of a kind of ventilation controlled by infrared induction
It fans to solve the above-mentioned problem.
Utility model content
In view of the deficienciess of the prior art, the utility model aim is to provide a kind of ventilation controlled by infrared induction
Fan, to solve the problems mentioned in the above background technology, the utility model is easy to use, easy to operate, and systematicness is high, practicability
By force.
To achieve the above object, the utility model provides the following technical solutions：A kind of ventilation controlled by infrared induction
Fan, including cover, Fresnel Lenses, infrared induction switch, power control board, flabellum, motor, motor fixing frame, main body rack
And rear cover, the motor are fixed at by motor fixing frame inside main body rack, the output end of the flabellum and motor is solid
Fixed connection, in main body rack rear end, the cover is arranged in main body rack front end, the infrared induction switch for the rear cover setting
It is assembled in inside main body rack with power control board integral type, the Fresnel Lenses is embedded in main body rack front end face lower-left rib
At angle.
Further, the motor and infrared induction switch are electrically connected with power control board, and the power supply controls
Plate is electrically connected with external power supply.
Further, cover front end face lower-left edges and corners offer the putting hole inlayed for Fresnel Lenses.
Further, cover front end face centre position offer air feed by through-hole.
Further, the rear cover and cover are connect by connecting screw with main body rack.
Compared with prior art, the utility model has the beneficial effects that：This equipment is controlled using this infrared induction switch
Afterwards, people is realized to take a breath, and people walks to stop the automation control of ventilation, saves electric energy, prolongs the service life, sometimes people leaves
After require flabellum that can rerun a bit of time, have delay controller on power control board, arrived the time of setting, flabellum stops
Rotation stop is dynamic, achievees the effect that intelligent control.
Description of the drawings
Fig. 1 is the explosive view of the utility model；
Fig. 2 is the front view of the utility model；
Fig. 3 is the partial structural diagram of the utility model.
In reference numeral：1. cover；2. Fresnel Lenses；3. infrared induction switch；4. power control board；5. flabellum；6.
Motor；7. motor fixing frame；8. main body rack；9. rear cover.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The all other embodiment obtained, shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of ventilation fan controlled by infrared induction,
Including cover 1, Fresnel Lenses 2, infrared induction switch 3, power control board 4, flabellum 5, motor 6, motor fixing frame 7, main body
Holder 8 and rear cover 9, motor 6 are fixed at by motor fixing frame 7 inside main body rack 8, the output end of flabellum 5 and motor 6
It is fixedly connected, the setting of rear cover 9 is in 8 rear end of main body rack, and the setting of cover 1 is in 8 front end of main body rack, infrared induction switch 3 and electricity
Control panel 4 integral type in source is assembled in inside main body rack 8, and Fresnel Lenses 2 is embedded in 8 front end face lower-left corner angle of main body rack
Place after this equipment is controlled using this infrared induction switch 3, realizes people to take a breath, and people walks to stop the automation control of ventilation,
Electric energy is saved, prolongs the service life, requires flabellum 5 that can rerun a bit of time after sometimes people leaves, in power control board 4
On have delay controller, arrived the time of setting, flabellum 5 stops operating, and achievees the effect that intelligent control.
Motor 6 and infrared induction switch 3 are electrically connected with power control board 4, and power control board 4 and external power supply electricity
Property connection, 1 front end face lower-left edges and corners of cover offer the putting hole inlayed for Fresnel Lenses 2,1 front end face interposition of cover
Set offer air feed by through-hole, rear cover 9 and cover 1 are connect by connecting screw with main body rack 8.
When the utility model at work：Infrared induction switch 3 is higher than absolute zero-in any object temperature of nature
273 DEG C, infra-red radiation is always constantly sent out, the temperature of object is higher, and the infra-red radiation peak wavelength that it is emitted is smaller,
The energy for sending out infra-red radiation is bigger；When people enters induction range, pyroelectric infrared sensor detects human body infrared spectrum
Variation, by Fresnel lenses enhancing gather in infrared induction source, change receiving human infrared radiation temperature
When will lose charge balance, discharge charge outward, subsequent conditioning circuit can trigger infrared induction switch 3 after handling after testing dynamic
Make, automatic processing circuit, drives output end rotation driving 5 rotary work of flabellum of motor 6, people that will be held without departing from induction range
Continued access is logical；After people leaves, circuit is automatically closed, the output end and flabellum 5 of motor 6 stop operating, to solve the prior art
Middle ventilation fan needs artificial control switch, and when user of service forgets to close, ventilation fan is run always, wastes electric energy, simultaneously
Larger, the problem of having shortened the service life is lost.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above, for
