Background

According to the conventional gas stove thermocouple ignition structure, please refer to fig. 1, which mainly comprises a stove head 1, an ignitor 2, a gas switch 3 and a thermocouple 4, wherein the stove head 1 comprises a stove head body 10 and a stove cover 15, the stove head body 10 is at least divided into an inner ring air chamber 11, an outer ring air chamber 12, an inner ring mixing pipe 13 and an outer ring mixing pipe (not shown), and the inner ring mixing pipe 13 and the outer ring mixing pipe are respectively and independently communicated with the inner ring air chamber 11 and the outer ring air chamber 12, and the stove cover 15 can be sleeved above the stove head body 10, so that a flame hole 16 is formed at the joint of the stove cover 15 and the stove head body 10, and gas can be sprayed out from the flame hole 16 to the outside; in addition, a thermocouple 4 is arranged at the side of the inner ring air chamber 11 of the burner 1, and the other end of the thermocouple 4 is connected to the gas switch 3;

an igniter 2, which is assembled on the gas switch 3, and one end of the igniter 2 is just located outside the outer ring gas chamber 12 of the burner 1; the igniter 2 includes a striking terminal 20 and a main fire tube 25, wherein one end of the striking terminal 20 is assembled on the gas switch 3 by a conducting wire 21, and the other end thereof is located on the flowing path of the gas sprayed from the main fire tube 25, and the other end of the main fire tube 25 can be assembled and connected to the gas switch 3 by a guiding tube 26;

by the above structure, when the rotary gas switch is ignited, the gas ejected from the main fire tube 25 is instantly ignited by the spark action of the ignition terminal 20 and is ejected to the vicinity of the flame hole 16 of the outer ring air chamber 12 of the burner 1, and the outer ring burner and the inner ring burner are sequentially ignited after the gas is ejected from the flame holes 16 of the

air chambers

11, 12 of the burner 1, and the flame is directly burned from the flame hole 16 of the inner ring air chamber 11 to the thermocouple 4, so that the thermocouple 4 forces the gas supply source in the gas switch 3 to be in a normally open state, thereby achieving the effect of continuously supplying and igniting the gas;

although the above-mentioned creation can achieve the original set creation purpose and is well approved by the industry and ordinary operators, in view of the fact that the research and development of the technology in the industry are different day by day and night, the applicant should make further efforts to research and improve the technology to make it perfect and practical; recently, the authors have found the following problems to be improved after undergoing numerous updating experimental tests and concluding the response opinions of the actual operation of the consumers:

when a cook or a housewife is busy or has poor memorability, and is required to carry out manual work and stew and boil food for a long time, the large flame or the small flame at the burner end can boil the pot to be the most dry state, even the pot is continuously kept burning, so that the pot is ignited to cause a fire, the gas switch can still continuously supply gas to the burner end for burning, and further, an unrecoverable fire is caused.

The temperature of the fire sprayed and burned by a common household gas stove is about 300 ℃ to 600 ℃, so that the thermocouple still has normal operation function when the fire is directly burned at the thermocouple; however, when the thermocouple is applied to a commercial stove or a blowing-type stove, the combustion temperature of the stove is increased to above 650 ℃, so that the ultrahigh heat resistant temperature (above 650 ℃) is directly burnt at the head end of the thermocouple, the thermocouple is broken due to direct high heat burning for a long time, the service life of the thermocouple cannot be used continuously, and meanwhile, the production must be stopped and additionally maintained and updated, so that the total cost consumed by manual maintenance and shutdown production is greatly increased.

The stove fire sprayed by a common household gas stove burns at a single thermocouple to generate a low micro-voltage instantly, and the low micro-voltage is only enough to effectively start the electromagnetic valve to perform the valve sucking action and can not be used by other electrical equipment any more, so that the application range of the household gas stove is narrow, which is another problem.

Therefore, how to develop a method for rapidly and progressively generating high total micro-voltage, so that the high total micro-voltage can overcome the impedance required by the connection point connected to the power control equipment and can be used to supply the micro-current required by the power control equipment during starting, and can achieve the safety operation with rapid heat dissipation and rapid valve closing, which is the technical subject that the practitioner needs to solve at present.

When a pot (not shown) located above the burner 61 is boiled to be dry, the pot will continue to absorb the heat energy of the stove fire of the burner 61, so that the temperature of the pot will be rapidly raised and will conduct the temperature to the power control device 5 located below the pot, until the temperature conducted to the power control device 5 reaches a predetermined value, the power control device 5 located in the closed loop will be turned on to form a disconnection phenomenon (i.e. a circuit breaking loop is formed among the solenoid valve 3, the thermocouple group 4 and the power control device 5), so that the micro-voltage generated by the thermocouples 41 cannot be conducted to the solenoid valve 3, so that the solenoid valve 3 no longer forms an excitation phenomenon, and the valve plate located in the solenoid valve 3 can be blocked between the front chamber of the switch valve group 1 and the main chamber, so as to block the gas from flowing into the valve seat 11 and simultaneously cut off the gas required by the ever-burning fire group 2 and the burner 61 (i.e. to present a flameout state), thereby avoiding the accidental occurrence of over-temperature fire caused by the continuous gas supply combustion.
