Road is filtered by electrolytic capacitor C1, obtains 5V DC voltage after integrated voltage-stabilized chip IC1 pressure stabilizing；Another way passes through electrolytic capacitor C2
Filtering obtains 12V DC voltage and uses for subsequent conditioning circuit after integrated voltage-stabilized chip IC2 pressure stabilizing；
It is just switched on power supply, the voltage on electrolytic capacitor C9 cannot be mutated, and the 9 foot voltages of display driving integrated chip IC4 are
Low level, 8 feet export high level, and triode BG5 cut-off, relay J5 must not be electric, and normally opened contact J5-1 and J5-2 are disconnected, sound
Light-emitting diode LED 1, LED2, loudspeaker SW and the motor exhaust M of optical alarm circuit do not work, can prevent just be switched on by
Cold conditions (there are no normal table work) is in gas sensor BA and generates malfunction；About 1 minute or so, electrolytic capacitor
C9 is full of voltage, and display drives the 9 foot voltages of integrated chip IC4 for high level, 8 feet output low level, triode BG5 conducting,
Relay J5 obtain it is electric, normally opened contact J5-1 and J5-2 closure, for sound light alarming circuit Light-emitting diode LED 1, LED2, raise
Ready work is ready in the work of sound device SW and motor exhaust M.
When the concentration of indoor soot gas is less than 0.15%, the resistance value of gas sensor BA is larger, divides with resistance R4
Afterwards, output voltage is lower, and 10,11,12,13 feet of hex inverter chip IC 3 export high level, triode BG1, BG2,
BG3, BG4 cut-off, relay J1, J2, J3, J4 must not electricity, the normally opened contact of the normally opened contact J1-1 of relay J1, relay J4
J4-2 is disconnected, and sound-light alarm and motor exhaust M do not work；When the concentration of indoor soot gas reaches response or more, air-sensitive
The resistance value of sensor BA becomes smaller, and after resistance R4 partial pressure, output voltage is increased, and 13 feet of hex inverter chip IC 3 are defeated first
Low level out, triode BG1 conducting, relay J1 obtain electric, normally opened contact J1-1, J1-2 of relay J1 closure, capacitor C12,
C13, C14, C15 and resistance R14 form phase-shift circuit, and equivalent shift capacitor is C12 at this time, and capacitance is larger, two-way controllable
The angle of flow of silicon SCR is smaller, and the electric current for flowing through smoke exhaust fan M is smaller, and the revolving speed of smoke exhaust fan M is slower；If indoor oil at this time
The concentration of flue gas body continues growing, then 12 feet of hex inverter chip IC 3 also export low level, triode BG2 conducting, relay
J2 obtains electric, and the normally opened contact J2-1 of relay J2 closure, normally-closed contact J2-2 is disconnected, and equivalent shift capacitor is C12 and C13 at this time
Series connection, capacitance reduce, and the bidirectional triode thyristor SCR angle of flow increases, and smoke exhaust fan M revolving speed becomes larger, and draft becomes strong；Similarly, when
When the concentration of indoor soot gas continues to increase, then 11 feet of hex inverter chip IC 3 also export low level, and triode BG3 is led
Logical, relay J3 obtains electric, the normally opened contact J3-1 closure of relay J3, normally-closed contact J3-2, J3-3 disconnection, at this time equivalent phase shift
Capacitor is C12, C13 and C14 series connection, and capacitance further decreases, and the bidirectional triode thyristor SCR angle of flow increases, and smoke exhaust fan M turns
Speed continues to become larger, and wind-force continues to increase；Finally, when the concentration of indoor soot gas reaches peak, then hex inverter chip
10 feet of IC3 also export low level, triode BG4 conducting, and relay J4 obtains electric, the normally opened contact J4-1 closure of relay J4,
Normally-closed contact J4-2, J4-3, J4-4 are disconnected, and equivalent shift capacitor is C12, C13, C14 and C15 series connection at this time, and capacitance is
Minimum, the bidirectional triode thyristor SCR angle of flow are maximum, and smoke exhaust fan M revolving speed reaches maximum value, and wind-force reaches maximum value；Conversely, working as
When the concentration decline of indoor soot gas, smoke exhaust fan M revolving speed can be gradually decreased.
Before the concentration of indoor soot gas is not up to peak, relay J4 must not be electric, the normally opened touching of relay J4
Point J4-2 is disconnected, and 1 foot of display driving integrated chip IC4 is clamped by diode D7 in low level, by resistance R9, capacitor 10 and is shown
