[0029] In the embodiment, the first gas outlet hole 6 is arranged on the outer periphery of the small fire cover 2, the second gas outlet hole 7 is arranged on the outer periphery of the large fire cover 1, and the first gas outlet hole 6 and the second gas outlet hole 7 guide the corresponding gas to be inclined upward and sprayed away from the temperature measuring probe 5. In this way, the flames are sprayed outward by the large fire cover 1 and the small fire cover 2 and are inclined upward, compared with the existing stove burner, the inward flame outlet is removed, the burning of the inward sprayed flame on the temperature measuring probe 5 is reduced, the deviation between the temperature measured by the temperature measuring probe 5 and the actual temperature in the pot is reduced, the accuracy of temperature detection is improved, and the false triggering of the dry burning prevention function of the stove is avoided.

[0030] It can be understood that the cross-sectional shape of the first gas outlet hole 6 and the second gas outlet hole 7 can be set according to requirements, such as circular, rectangular, oval, etc., which is not limited herein, and is circular in the present application.

[0031] In combination with the first aspect, the upper edge of the small fire cover 2 is provided with a outwardly protruding eave 8 (in combination with Figure 2 As shown, the inner base 4 and the outer base 3 are provided with an ignition needle 9, the ignition needle 9 is located at a corresponding position below the eave 8, the needle head of the ignition needle 9 is slightly lower than the eave 8 and close to the first gas outlet hole 6.

[0032] In combination with Figure 2 As shown, the eave 8 protrudes outwardly, the needle head of the ignition needle 9 is slightly lower than the eave 8, the eave 8 blocks the outward diffusion of the electric spark, which can shorten the distance between the ignition needle 9 and the small fire cover 2, the spark is more likely to produce discharge when the ignition needle 9 is ignited, thereby improving the ignition success rate.

[0033] In combination with the first aspect, the upper surface of the small fire cover 2 is further provided with an inner ring barrier wall 10 and an outer ring barrier wall 11, both of which are concentric with the inner base 4, and the outer ring barrier wall 11 is provided with a gap 19 for guiding the flow.

[0034] During the cooking process, the liquid in the pot boils and overflows from the edge of the pot, and the overflowing liquid flows down along the outer wall of the pot. In the present application, the upper surface of the small fire cover 2 is further provided with an inner ring barrier wall 10 and an outer ring barrier wall 11, and the space enclosed by the inner ring barrier wall 10 and the outer ring barrier wall 11 is used to receive the above-mentioned liquid flow, and the outer ring barrier wall 11 is provided with a gap 19 for guiding the flow, so that the liquid flow can flow out along the gap 19 in the case of accumulation. By guiding the overflowing liquid flow through the above-mentioned structure, it can avoid the overflowing liquid flow to extinguish the flame generated by the large fire cover 1, and also can reduce the pollution of the liquid flow to the stove. The number of gaps 19 can be more. In the present embodiment, the number of gaps 19 is 1.

[0035] In combination with the first aspect, the large fire cover 1 is provided with a fire guiding groove 12 extending from the inner side of the large fire cover 1 to the second gas outlet hole 7. The fire guiding groove 12 extends from the inner side of the large fire cover 1 to the second gas outlet hole 7, which is to guide the flow of flame or gas. In the process of ignition by the user, the gas is sprayed out from the first gas outlet hole 6 of the small fire cover 2, the ignition needle 9 strikes a spark and ignites the gas around the small fire cover 2. Due to the existence of the fire guiding groove 12, the gas and flame around the small fire cover 2 can flow more quickly along the fire guiding groove 12 to the second gas outlet hole 7 of the large fire cover 1, thereby igniting the gas sprayed out from the second gas outlet hole 7, and more efficiently completing the ignition process.

[0036] In combination with the first aspect, a liquid accumulation disc 13 is provided below the burner head seat corresponding to the gap 19, and the bottom of the outer seat 3 is provided with a water overflow hole 14. Under the blocking action of the inner ring barrier wall 10 and the outer ring barrier wall 11 on the small fire cover 2, the liquid flow generated by the pot overflow is guided to flow out at the gap 19, thereby entering the liquid accumulation disc 13 under the action of gravity. In order to avoid the waste liquid in the liquid accumulation disc 13 from accumulating too much and causing the corresponding liquid level to continue to rise and affect the work of the stove, the present application provides the water overflow hole 14 at the bottom of the outer seat 3, so that the waste liquid has a certain flow space and can continue to flow outward through the corresponding water overflow hole 14.

[0037] In combination with the first aspect, the burner head seat is detachably arranged on the liquid accumulation disc, and the outer periphery of the liquid accumulation disc 13 is further embedded with an inner recessed water arching disc 15, and the liquid accumulation disc is detachable.

[0038] The middle of the water arching disc 15 is low and the outer periphery is high, and the waste liquid flowing out of the water overflow hole 14 will be received in the water arching disc 15 and tend to gather in the center direction of the liquid accumulation disc 13 under the action of gravity, thereby avoiding the waste liquid from overflowing from the burner head structure to the tabletop of the stove. In addition, the liquid accumulation disc 13 is detachable, and when cleaning, the liquid accumulation disc 13 under the burner head seat can be taken out and the waste liquid can be poured out, and the detachable structure is convenient for cleaning.

[0039] In combination with the first aspect, the thermocouple 16 is additionally provided between the inner seat 4 and the outer seat 3, and the small fire cap 2 is provided with more first gas outlet holes 6 at the thermocouple 16 and the ignition needle 9 than at other positions.

[0040] In the present application, the temperature measuring probe is used to abut against the bottom of the pot and detect the temperature of the pot bottom, while the thermocouple provided between the inner seat 4 and the outer seat 3 is used to detect the temperature of the flame generated by the burner. Among them, the thermocouple 16 is additionally provided with more first gas outlet holes 6, so that the fire in this area is larger, so that the thermocouple can be quickly heated to transmit the corresponding temperature signal. In addition, the ignition needle 9 is also additionally provided with more first gas outlet holes 6, so that the gas supply in this area is more sufficient, so as to complete the corresponding ignition operation.

[0041] In combination with the first aspect, the air door mechanism 17 is used to mix the gas and air to provide the burner with gas and air. Figure 1 As shown.

[0043] In combination with the first aspect, the pot rack 18 is used to support the corresponding pot, and the temperature measuring probe 5 is elastic and used to abut against the bottom of the pot for temperature measurement.

[0044] In actual use, the pot is placed on the pot rack 18, the pot is supported by the pot rack 18, the air door mechanism 17 delivers the mixed gas to the small fire cap 2 and the large fire cap 1, the mixed gas is ignited under the action of the ignition needle 9, the flame is conducted from the small fire cap 2 to the large fire cap 1, the ignition process is completed, and the cooking of the food in the pot is started. During this process, the pot exerts a force on the elastic temperature measuring probe 5, and under the action of the reaction force, the top of the elastic temperature measuring probe 5 abuts against the center of the bottom of the pot, so that the actual temperature inside the pot is represented by the temperature detected by the temperature measuring probe 5 at the center of the bottom of the pot. Since the flames generated by the large fire cap 1 and the small fire cap 2 both deviate from the temperature measuring probe 5, the burning of the temperature measuring probe 5 by the flames is effectively avoided, the deviation between the temperature measured by the temperature measuring probe 5 and the actual temperature inside the pot is reduced, and the temperature measured by the temperature measuring probe 5 is closer to the actual temperature inside the pot, thereby greatly improving the accuracy of temperature monitoring.

[0045] In the present application, the temperature measuring probe is used to abut against the bottom of the pot and detect the temperature of the pot bottom, while the thermocouple provided between the inner seat 4 and the outer seat 3 is used to detect the temperature of the flame generated by the burner. Among them, the thermocouple 16 is additionally provided with more first gas outlet holes 6, so that the fire in this area is larger, so that the thermocouple can be quickly heated to transmit the corresponding temperature signal. In addition, the ignition needle 9 is also additionally provided with more first gas outlet holes 6, so that the gas supply in this area is more sufficient, so as to complete the corresponding ignition operation.

[0046] In the present application, the temperature measuring probe is used to abut against the bottom of the pot and detect the temperature of the pot bottom, while the thermocouple provided between the inner seat 4 and the outer seat 3 is used to detect the temperature of the flame generated by the burner. Among them, the thermocouple 16 is additionally provided with more first gas outlet holes 6, so that the fire in this area is larger, so that the thermocouple can be quickly heated to transmit the corresponding temperature signal. In addition, the ignition needle 9 is also additionally provided with more first gas outlet holes 6, so that the gas supply in this area is more sufficient, so as to complete the corresponding ignition operation.

[0047] In this way, compared with the existing stove burner, the inward fire outlet is removed, the inwardly ejected flame can be avoided to burn the temperature measuring probe 5, so that the temperature measured by the temperature measuring probe 5 is closer to the actual temperature inside the pot, and the accuracy of temperature monitoring is greatly improved.
