Embodiment
The touch panel switch S1 of embodiment 1. closes, and the intelligent gas-burning stove circuit enters working condition.First, in start-oscillation circuit
In the presence of, the single-chip microcomputer U1 in single chip machine controlling circuit starts working according to program.Single-chip microcomputer U1 3 pin output high level, 3
4 pin for the timer U3 that the high level of pin output passes through in firing circuit.Timer U3 4 pin are once high level, timer
U3 starts working, and its 3 pin exports the square wave of height.Now timer U3 links together because of 6 pin and 2 pin, so constituting many
Harmonic oscillator, its cycle of oscillation is depending on resistance R2, R3, R4 and electric capacity C4.Timer U3 3 pin output high level passes through resistance
R5, then electric current be amplified by triode Q1, igniter U4 starts to light combustion gas after amplification, the triode Q1 simultaneously turned on
So that green is given out light, diode D1 starts flashing.After combustion gas is lighted, the temperature sensor U2 inspections in single chip machine controlling circuit
Temperature is measured, signal feeding the single-chip microcomputer U1, single-chip microcomputer U1 of detection then export low level in its 4 pin, and low level can not then drive
Warning circuit, so loudspeaker are not alarmed, gas-cooker also normal work.
The touch panel switch S1 of embodiment 2. closes, and the intelligent gas-burning stove circuit enters working condition.Under certain reason, point
Firearm, which does not light combustion gas or supplies deficiency etc., causes fiery extinguishing.In this case, the temperature in single chip machine controlling circuit is passed
Sensor U2 then can't detect temperature, if can't detect temperature, and signal is then sent into single-chip microcomputer U1 by temperature sensor U2.Single-chip microcomputer
U1 then exports high level in its 4 pin, and the high level of output is by the red light emitting diodes D2 in warning circuit, emitting red light two
Pole pipe D2 sends feux rouges, and then current signal amplifies by triode Q2, and the signal after amplification is reported by loudspeaker Speaker
It is alert.Send feux rouges and loudspeaker alarm represents gas-cooker irregular working, thus user can be reminded to light a fire or close again
Fuel gas source.
