The bottom of the outer ring fire cover is provided with a fourth joint 34 and a fifth joint 35 in turn on the inner and outer circumferences, the first joint 23 is plugged into the first interface 101, and the second joint 43 is connected to the second The second interface 102 is inserted, the third joint 44 is inserted into the third interface 201 , the fourth joint 34 is inserted into the fourth interface 202 , and the fifth joint 35 is inserted into the fifth interface 203 . The fire cover base 2, the outer ring fire cover 3, and the inner fire cover 4 can be easily and conveniently removed or placed, and the fire cover and the cooking surface can be cleaned conveniently.

Wherein, the temperature sensor 5 includes a temperature probe 51 , a through hole 42 is provided in the center of the inner fire cover 4 , and the temperature probe 51 protrudes upward from the through hole 42 . During the use of the stove, the temperature probe 51 of the temperature sensor can detect the temperature of the pot. When the water in the pot boils dry or the oil reaches a high temperature of 300 degrees, the temperature probe 51 can detect that the temperature is too high, and immediately cut off the gas source to prevent safety hazard.

In order to isolate the temperature probe 51 from the flame, the outer cover of the temperature probe 51 is provided with a flame isolation cover 53 for isolating the flame, and an air insulation layer is formed between the temperature probe 51 and the flame isolation cover 53 . When the burner is in use, the flame isolation cover 53 isolates the flame, so that the temperature probe 51 will not be burned by the flame, and the temperature probe 51 will not be misjudged or burned out.

Further, the second interface 102 extends downwards to form a cooling channel. The hot air in the upper part of the burner flows toward the upper part of the space, and at the same time, it also drives the cold air in the lower part to flow upward through the cooling channel in the center of the burner and the air insulation layer in the flame isolation cover 53, absorbing and reducing the temperature of the temperature probe 51. Therefore, the temperature sensor 9 can be continuously cyclically cooled to ensure the sensitivity and service life of the temperature sensor.

In addition, the temperature probe 51 is provided with a cylindrical portion, and a support spring 52 is provided in the cylindrical portion to elastically support the temperature probe upward. The bottom of the supporting spring 52 is installed on the pole 15, and the pole 15 is fixed on the furnace head. Therefore, under the elastic action of the support spring 52, the temperature probe 51 can always keep in contact with the bottom surface of the pot, which ensures the sensitivity of the temperature sensor.

The inner fire cover 4 is provided with a central mixing chamber and is distributed with micro-fire holes 41 communicating with the central mixing chamber along the circumferential direction, and the outer ring fire cover 3 is provided with an outer ring mixing chamber and is communicated with the outer ring mixing chamber along the circumferential direction. Large fire hole, described big fire hole comprises the inner ring flame injection hole 31 that is located at outer ring fire cover 3 inner rings, the outer ring fire injection hole 32 that is located at outer ring fire cover 3 outer rings. The burner head 1 is provided with an outer ring fire injection pipe 11 communicated with the outer ring mixing chamber and a small fire injection pipe 12 communicated with the central mixing chamber, and the inlet end of the outer ring fire injection pipe 11 is provided with The outer ring fire gas nozzle and the main fire air inlet, the inlet end of the small fire injection pipe 12 is provided with an inner ring fire gas nozzle and an inner ring fire air inlet. The gas outlet end of the outer ring fire injection pipe 11 is provided with an outer ring fire mixing channel 111, and the outer ring fire mixing channel 111 communicates with the outer ring mixing chamber, and the gas outlet end of the small fire injection tube 12 is provided with an inner ring fire mixing channel 111 A mixing channel 121, the inner ring fire mixing channel 121 communicates with the central mixing chamber. The air and gas are mixed for the first time in the outer ring fire injection pipe 11 and the small fire injection pipe 12, then enter the outer ring fire mixing channel 111, and the inner ring fire mixing channel 121 for the second mixing, and then enter the outer ring mixing chamber and the central mixing chamber for the third mixing, and finally a uniform mixed gas is sprayed from the small fire hole 41 and the large fire hole, so that the gas and oxygen are mixed and burned, thereby greatly improving the gas utilization rate, thereby reducing carbon and NOx emissions.

In this embodiment, a fire slit 33 is provided between the inner ring fire injection hole 31 and the outer ring fire injection hole 32 . The ignition seam can quickly ignite the inner ring fire ignited by the kindling to the outer ring fire, and the flame injection holes support each other to make the outer ring fire burn stably.

In order to ensure that the burning flame is in the center of the pot, it can be set in such a way that the bottom surface of the fire cover base 2 is evenly distributed with uniform placement points 22 of uniform height along the circumferential direction. A plurality of balanced placement points 22 are evenly supported on the cooker table, which can ensure that the burning flame is in the center of the cooker, so as to meet the user's need for a fire point.

Further, the burner 1 is made of aluminum, which is lighter in density than the cast iron burner, and its volume is much smaller than that of the cast iron burner, which greatly reduces the force requirement on the cooker bottom shell and improves the deformation.

In addition, the burner of the present invention can also adopt other conventional settings, for example, for the convenience of ignition, an ignition device is provided on the burner head. In order to ensure safe use, the burner is provided with a flameout protection device. The ignition device includes an ignition needle 13, and the ignition needle 13 is fixedly installed at the center of the burner head. The flameout protection device includes a thermocouple 14 and a solenoid valve, and the thermocouple 14 is fixedly installed on the furnace head. The small fire hole 41 on the inner fire cover 4 faces the thermocouple 14. After the fire is accidentally extinguished, the thermocouple 14 can detect it quickly, and the solenoid valve responds quickly and closes the gas, which can prevent the safety hazard of gas leakage. The micro flame hole is oriented towards the thermocouple and the ignition pin, making it easier for the thermocouple to detect the flame and the ignition pin spark to ignite the kindling more easily.

A protective umbrella 45 covering the ignition needle is provided on the side of the inner fire cover 4 . The ignition needle 13 is under the protective umbrella 45, so it will not be wetted by liquid and adhered to oily residue, which greatly reduces the phenomenon of ignition failure, thereby greatly reducing the ignition time of the burner, and improving the service life of related electrical components and complete machines.

When the burner of the present invention is working, the pot containing the ingredients is placed on the stove, the temperature probe 51 of the temperature sensor 5 touches the bottom of the pot, the ignition is started, an arc is generated between the ignition needle 13 and the protective umbrella 45, and the inner fire cover 4 ejects The small fire gas is ignited, and the flame isolation cover 53 isolates the flame and the temperature probe 51 that the inner fire cover 4 sprays. The thermocouple 14 detects the flame temperature, and the electromagnetic valve is opened to control the outer ring fire cover 3 to eject gas and be ignited by the small fire flame of the inner fire cover 4 . The burner head 1 is provided with an annular sunken secondary air supply channel between the inner fire cover 4 and the inner ring of the outer ring fire cover 3, and the outside air passes through the secondary air supply channel to form the inner fire cover 4 and the outer ring fire cover 3 The ejected flame supplies oxygen for secondary combustion.

The above is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the accompanying drawings and the description in the above specific embodiments content. Any modifications that do not depart from the functional and structural principles of the present invention will be included in the scope of the claims.
