Thermocouple anti-air-burning structure of burner

Abstract

The invention discloses a thermocouple anti-air-burning structure of a burner, comprising a valve body, a burner, a heated container, a solenoid valve group, a high-temperature micro-voltage thermocouple, and a low-voltage micro-voltage thermocouple in contact with the surface of the heated container. The high-temperature micro-voltage thermocouple and the low-temperature micro-voltage thermocouple are connected in series reversely to form a loop. The burner can burn the heated container and the high-temperature micro-voltage thermocouple. The heated container can conduct heat to the low-temperature micro-voltage thermocouple to generate a reverse micro-voltage, and the burner directly burns the high-temperature micro-voltage thermocouple to generate a forward micro-voltage. When the excitation valve force generated on the solenoid valve group by a difference obtained by subtracting the reverse micro-voltage from the forward micro-voltage is smaller than the reaction force of the valveseat of the solenoid valve group, the valve seat of the solenoid valve group can block the entrance of the passage of the valve body, thereby blocking the supply gas from flowing into the valve bodyto achieve the effect of anti-air burning.

Description

technical field [0001] The invention relates to a thermal couple type air-proof burning structure of a burner. Background technique [0002] Existing gas burner head ignition structure, refer to figure 1 , which mainly includes a burner head 1, an ignition device 2, a gas switch 3 and a thermocouple 4, wherein the burner head 11 includes a burner head body 10 and a furnace cover 15, and the burner head body is provided with an inner ring gas chamber 11, The outer ring air chamber 12, the inner ring mixing tube 13 and the outer ring mixing tube (not shown in the figure), and the inner ring mixing tube 13 and the outer ring mixing tube are independently connected to the inner ring air chamber 11 and the outer ring air chamber 12, and the furnace cover 15 can be placed on the top of the burner body 10, so that a flame hole 16 is formed at the junction of the furnace cover 15 and the burner body 10, and the gas gas can be ejected from the flame hole 16 to the outside; the burne...

Problems solved by technology

[0006] When chefs or housewives are busy or have poor memory, they perform multiple tasks at the same time and cook food for a long time, often causing the large flame or small flame at the stove to burn the pot dry , or even keep burning to ignite the pot and then cause a fire. At this time, the gas switch will still supply the gas supply gas to the burner for burning, thus causing an uncontrollable fire
