The characteristic of portion's semistor, after it reaches certain high temperature, resistance is very big, and whole circuit is in close to off state,
Therefore, its electric power is extremely low, will not additionally bring excessive power consumption.
(2) when needing to close fuel gas buring, then closing control switch, aforementioned surface ignition device 10 and wax motor 20 are in disconnected
Electricity condition, the critesistor within wax motor 20 is gradually lowered the temperature, and the piston rod of wax motor 20 inwardly retreats and retracts sealing slide block 33,
Release the effect that pushes to push rod, the inlet end closure of valve inside 32, that is, cut off fuel gas transmission；Switch to complete in closing control
During cut-out fuel gas transmission, the combustion gas that it is conveyed continues to be completely burned to the greatest extent.
The design focal point of the present invention is, it is mainly by being series at surface ignition device and wax motor in same circuit
Synchronization Control on/off is come by a controlling switch；Using both different qualities, it is required that surface ignition device reaches igniting in advance
High temperature, is in prefiring state before ventilation, and the piston rod of wax motor is delayed to opening the inlet end of valve inside to convey combustion
Gas, its combustion gas exports is lighted safely to the high temperature surface touching surface ignition device, and real realization full-automation " is first lighted a fire
Ventilate again ", prevent the phenomenon of unburned combustion gas air inlet during ignition operation, it uses safety, energy-conserving and environment-protective；
Meanwhile, during combustion gas after firing uses, due to the internal semistor of wax motor itself
Characteristic, after it reaches certain high temperature, resistance is very big, makes whole circuit close to off state, therefore, its electric power is extremely low, no
Excessive power consumption can additionally be brought.
The above, be only presently preferred embodiments of the present invention, not the technical scope of the present invention imposed any restrictions,
Therefore any trickle amendment, equivalent variations and modification that every technical spirit according to the present invention is made to above example, all still
Belong in the range of technical solution of the present invention.
