That is, when the air exhausting device 10 of the present invention is a range hood and the application device 20 is a range hood as an example, since the intelligent knob 201 installed on the range hood performs the angle of turning on ignition, the angle of turning off extinction, and the angle of rotation adjustment of small fire → large fire, which are set separately in advance, the angle and the spatial attitude of rotation of the intelligent knob 201 can be accurately measured and detected by the built-in rotation angle detection module 2011, and the measured sensing signal is synchronously transmitted to the speed adjusting module 30 in a wireless communication manner, and after the speed adjusting module 30 receives the sensing signal from the intelligent knob 201, the electrically connected utility power source 1 (ac power source) is correspondingly adjusted and changed, and the rotation speed of the power motor 101 of the electrically connected range hood is changed accordingly. Accordingly, the rotation speed of the exhaust fan 102 driven by the power motor 101 will be changed at the same time, so that the exhaust speed and the wind power of the exhaust fan 102 can be automatically and actively adjusted according to the rotation angle of the intelligent knob 201, and the intelligent knob 201 can automatically start the exhaust operation when turning on the ignition → the smoke exhaust ventilator. When the intelligent knob 201 rotates to the small fire → the smoke exhaust ventilator will automatically exhaust with small air volume; when the intelligent knob 201 rotates to a big fire → the smoke exhaust ventilator will automatically exhaust with a big wind amount; the intelligent knob 201 rotates to close and extinguish → the range hood will automatically close the air discharge. Therefore, the method not only has simple and convenient implementation, but also can keep the indoor air quality clean at any time, thereby achieving the effect of promoting the human health.
As shown in fig. 12, the speed regulation module 30 may also be electrically connected or communicatively connected to an Indoor Air Quality detector 40 (IAQ), since the general Indoor Air Quality detector 40 detects the Indoor Air Quality through a gas detector 401(Voc Sensor), and automatically classifies the detected Air Quality (e.g., detects the concentration of carbon monoxide, carbon dioxide, or dust …), and then displays different signals on the meter or gives an alarm. When the indoor air quality detector 40 is applied to the present invention, only the air quality signal detected by the gas detector 401 is transmitted to the speed regulation module 30 synchronously, and after receiving the air quality signals of different grades through the speed regulation module 30, the electrically connected utility power source 1 (ac power supply) is correspondingly and automatically regulated, and the rotation speeds of the power motor 101 and the exhaust fan 102 of the electrically connected exhaust equipment 10 are changed, and then the exhaust equipment 10 can be linked with the indoor air quality detector 40, so that the magnitude of the exhaust force is automatically and actively converted along with the air quality of different grades, thereby achieving the effect of ensuring the indoor air quality to maintain the best state at any time.
