1. the rotational speed of the power motor 101 can be varied by performing leading-edge phase control on the ac output using a Thyristor (Thyristor). Fig. 7 is a waveform diagram of an input ac power, and fig. 8 is a waveform diagram of a power supply of the modulated output power motor 101; the power output ratio of the speed regulation module 30 is controlled to control the output power, so as to control the rotation speed of the power motor 101.

In the present invention, the speed regulating module 30 is disposed between the power supply of the ac air exhausting device 10 and the commercial power source 1 (ac power source), and the speed regulating module 30 can regulate the input commercial power source 1 (ac power source) by the first microcontroller 302 and the power source regulating circuit 303, so as to change the input power of the power motor 101 of the air exhausting device 10, and the input power is also changed by the smart knob 201 disposed on the application device 20, and the current spatial attitude (including the angle and the position) is measured by the rotation angle detecting module 2011 and the second microcontroller 2012 disposed in the smart knob 201, and is synchronously transmitted to the speed regulating module 30 by the second microcontroller 2012 and the second wireless communication module 2013 according to the spatial attitude information of the smart knob 201, after the spatial attitude signal from the smart knob 201 is received by the first wireless communication module 301 disposed in the speed regulating module 30, the input power of the commercial power source 1 (ac power source) is regulated by the first microcontroller 302 and the power source regulating circuit 303, so that the input power of the power motor 101 is naturally linked, and the rotational speed of the power motor 101 is changed by the smart knob 102, so as to achieve the purpose that the exhaust device 10 is automatically changed according to the rotational speed of the application knob, and the smart fan 102.
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 angle of turning on the ignition, the angle of turning off the flameout, and the angle of rotating and adjusting the small fire → the big fire by the intelligent knob 201 installed on the range hood are respectively set in advance, the angle and the space attitude of the rotation of the intelligent knob 201 can be accurately measured and detected by the built-in rotation angle detecting module 2011, and the measured sensing signal is synchronously transmitted to the speed adjusting module 30 in a wireless communication manner, after the speed adjusting module 30 receives the sensing signal from the intelligent knob 201, the electrically connected commercial power source 1 (alternating current power source) is correspondingly adjusted and the rotating speed of the power motor 101 of the electrically connected range hood is changed. 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 the big fire → the smoke exhaust ventilator will automatically exhaust with the big wind; 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 (for example, detects the concentration of carbon monoxide or 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.
