Description
Technical field
The utility model relates to the gas impulse igniter that uses on a kind of indoor outer gas furnace tool, especially can discern the gas kitchen ranges that outage and fire prevention detect.
Background technology
At present, the pulse igniter that uses on the market, the function of its realization mainly contains: safe self check, IGNITION CONTROL, blowout protection, fault detect.If but power supply outage in use or battery come off, under burnt gas switch is not closed situation, following secondary source is normal connect after, gas-cooker is igniting automatically.In addition, when occurring in the use catching fire in the pot, combustion gas but burns away.These all cause fire easily in human negligence or when mishandling, do not play combustion gas safeguard measure safe in utilization.
Summary of the invention
The utility model will solve the existing gas-cooker problem that igniter can be lighted a fire automatically after power down is heavily switched on, and provides a kind of and can prevent the power-down fireproof protection pulse igniter of igniting automatically after outage is heavily switched on.
The technical solution of the utility model:
Power-down fireproof protection pulse igniter, comprise single-chip microcomputer, described single-chip microcomputer is connected with power-supplying circuit, crystal oscillating circuit, flame detection circuit, buzzer alarm circuit, ignition control circuit, solenoid valve control circuit, microswitch, described power-supplying circuit directly is connected with power supply, be connected with flame on the described flame detection circuit and detect pin, described single-chip microcomputer is connected power supply when the microswitch turn, the signal that sends the unlatching gas valve is to the control solenoid valve control circuit, send ignition signal to ignition control circuit, it is characterized in that: described single-chip microcomputer is provided with the port detecting unit that detects the port status of microswitch after outage when being used for re-powering automatically, as to detect microswitch be to be communicated with, described single-chip microcomputer is not sent out ignition signal and is given ignition control circuit, signals to buzzer alarm circuit; As to detect microswitch be to disconnect, and described single-chip microcomputer sends ignition signal to ignition control circuit when the microswitch turn.
Further, described single-chip microcomputer is connected with fire detecting devocw, described fire detecting devocw is two parallel band electric metals, described fire detecting devocw sends flare up fire to described single-chip microcomputer after utilizing the flame ion conductive characteristic to detect to catch fire in the pan flame, and described single-chip microcomputer sends after receiving flare up fire closes the gas valve signal to described solenoid valve control circuit.
When the microswitch turn, single-chip microcomputer detects its port voltage and changes judgement igniting action, opens gas valve, lights stove fire.Re-power after the outage, single-chip microcomputer autosensing port state is communicated with (not closing) as microswitch, then misfire, and alarm, prevent from when human negligence, to cause fire; Disconnect as microswitch, but normal ignition.Utilize the flame ion conductive characteristic, use two parallel band electric metals to do checkout gear.In normal use, detect the pan that uses on the kitchen range as fire detecting devocw and catch fire behind the flame, the fire detecting devocw conducting, single-chip microcomputer sends order and cuts out gas valve, extinguishes stove fire, stops the further increasing of the intensity of a fire.
The beneficial effects of the utility model: under the mishandling situation of in human negligence and pot, catching fire, can effectively guarantee the safe in utilization of household gas utensils; Simple in structure, safe and effective.
