The power supply of motor is that power supply is illuminated.
Such as: if be detected that storage capacitor C2 electricity is inadequate, then use mains-supplied LED illumination.
Thus, by using city's electric lighting when changing gained electric energy deficiency, it is ensured that user uses relaxing of smoke exhaust ventilator
Adaptive, reliability is high.
In an optional embodiment, it is also possible to including: switch power supply in lighting process.
In one example, with in the power supply of described electric energy and described motor can be at described lighting module 7
During power supply is illuminated, when described power supply is insufficient to power for described lighting module 7, by described power supply
Power supply switches to another in the power supply of described electric energy and described motor.
Such as: can be during described lighting module 7 is illuminated with described electric energy for power supply, when described electricity
When can be insufficient to power for described lighting module 7, the power supply of described lighting module 7 is switched to the power supply of described motor.
Such as: can also during described lighting module 7 is illuminated with the power supply of described motor for power supply,
When described electric energy is enough powered for described lighting module 7, the power supply of described lighting module 7 is switched to described electric energy.
Thus, switched over by the practical situation according to power supply when lighting hours is longer, on the one hand ensure that
The comfortableness that user uses, on the other hand can energy-conservation in the case of carry out energy-conservation, improve smoke exhaust ventilator further
Functional reliability and the experience of user.
In an optional embodiment, it is also possible to including: close illumination when ambient brightness is enough.
In one example, can be during described lighting module 7 be illuminated, when described brightness is higher than described pre-
If during value, closing described lighting module 7.
Such as: if brightness is sufficient, LED illumination (such as: LED) is closed.
Thus, by automatically controlling the blower fan of smoke exhaust ventilator and illumination, and kinetic energy is utilized in blower fan braking procedure
Carry out electric energy conversion, smoke exhaust ventilator can be made to be easy to use and more energy-conservation, thus preferably promote the experience of user.
The process realized due to the method for the present embodiment and function essentially correspond to the oil pumping shown in earlier figures 3 and Fig. 4

Close explanation, do not repeat at this.
Through substantial amounts of verification experimental verification, use technical scheme, by software, the combination of hardware, make smoke exhaust ventilator
Being easy to use and more energy-conservation, Consumer's Experience is good.
To sum up, skilled addressee readily understands that, on the premise of not conflicting, above-mentioned each advantageous manner can be certainly
By ground combination, superposition.
The foregoing is only embodiments of the invention, be not limited to the present invention, for those skilled in the art
For Yuan, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made,
Equivalent, improvement etc., within should be included in scope of the presently claimed invention.
