Abstract
The invention discloses a gas stove flameout alarm which can be used to monitor a gas stove and alarm. The gas stove flameout alarm contains an IC1-1 comparator, an IC1-2 follower; photoresistors R4 and R5 which are connected at the positive input end of the IC1-1 comparator; and parallel capacitors C1 and C2 which are connected between the IC1-1 comparator and the IC1-2 follower and is connected with AN, which is a reset integrator. The principle is as follows: the IC1-1 is used as a comparator and the IC1-2 is used as a follower; R4 and R5 are photoresistors and their resistance changes with illumination intensity; An is a reset integrator and is used for discharging electric charges of the capacitors C1 and C2. When the gas stove flameout alarm is used, the photoresistor R4 targets flame, and an ''adjustment knob'' is turned such that the alarm doesn't sound. The gas stove flameout alarm has high sensitivity and can be used to eradicate any occurrence of gas stove flameout accidents.
Description
Technical field
The present invention relates to a kind of alarm, specifically is a kind of gas burner flame failure alarm.
Background technology
Gas burner is city essential articles for use at home, the life security that its security performance affects the livelihood of every family.Gas burner is in case flame-out for some reason and not discovery in time is very dangerous, and for example the water is boiling, has little time in time to close to close to cause the excessive fire that makes of water to extinguish.At present, though some high-rank coal steam stove has auto extinguishing control protective device, price is high, is difficult to popularize.
Summary of the invention
For overcoming the above-mentioned deficiency of prior art, the present invention provides a kind of gas burner flame failure alarm, can keep watch on and reports to the police gas burner.
The present invention realizes with following technical scheme: a kind of gas burner flame failure alarm comprises the IC1-1 comparator, the IC1-2 follower; Be connected photo resistance R4, the R5 of IC1-1 comparator positive input terminal; At the IC1-1 comparator, be connected with the capacitor C 1, the C2 that are in parallel between the IC1-2 follower, capacitor C 1, the C2 of parallel connection are that reset switch is connected with AN.
Principle is: the IC1-1 device of making comparisons, and IC1-2 makes follower; R4, R5 are photo resistance, and its resistance changes with intensity of illumination; AN is a reset switch, the electric charge of be used to release electric capacity C1, C2; During use, at first aim at flame to photo resistance R4, rotate " adjusting knob " alarm is not reported to the police.
The invention has the beneficial effects as follows: highly sensitive, the generation that can stop the flame-out accident of gas burner.
Description of drawings
Accompanying drawing is an electrical schematic diagram of the present invention.
The specific embodiment
Comprise the IC1-1 comparator like gas burner flame failure warning device shown in the drawings, the IC1-2 follower; Be connected photo resistance R4, the R5 of IC1-1 comparator positive input terminal; At the IC1-1 comparator, be connected with the capacitor C 1, the C2 that are in parallel between the IC1-2 follower, capacitor C 1, the C2 of parallel connection are that reset switch is connected with AN.This circuit uses the 9V laminated cell.
Present embodiment circuit core device IC1-1, IC1-2 all adopts LM324 four high guaily unit device.The IC1-1 device of making comparisons, IC1-2 makes follower; R4, R5 are photo resistance, and its resistance changes with intensity of illumination; AN is a reset switch, the electric charge of be used to release electric capacity C1, C2; During use, at first aim at flame to photo resistance R4, rotate " adjusting knob " alarm is not reported to the police.Live flame with stick shift, should send chimes of doom this moment.General adjusting twice or thrice can reach requirement.
