[0002] Gas stoves are important kitchen appliances in people's daily lives. With the improvement of people's living standards, the performance requirements of gas stoves are getting higher and higher. In the current existing technology, the burner structure of gas stoves is as follows: Figure 1 As shown, it includes an ignition divider a, and a plurality of lower outer ring fire holes b and a plurality of upper outer ring fire holes c are circumferentially opened on the side wall of the ignition divider, and an ignition needle d is provided on the side of the ignition divider, and a spark avoidance interval e corresponding to the ignition needle is provided between the upper outer ring fire holes. When the burner of this structure is ignited, the first step is to ignite the lower outer ring fire hole through the ignition needle, and the second step is to ignite the upper outer ring fire hole with the flame ejected from the lower outer ring fire hole, thereby igniting the entire burner. This ignition method requires the upper outer ring fire to wait for the lower outer ring fire to ignite, thereby reducing the ignition efficiency and ignition success rate.

[0030] This burner adds an upper ignition hole between the upper outer ring fire holes 6, so that the ignition needle 10 can ignite the lower outer ring fire hole 5 and the upper outer ring fire hole 6 at the same time. The upper outer ring fire hole 6 does not need to wait for the lower outer ring fire hole 5 to ignite, which can improve the ignition efficiency, save ignition time, reduce gas accumulation, avoid deflagration, ensure ignition safety, reduce gas waste, and ensure the ignition success rate.

[0031] The width of the upper ignition hole 7 is the same as the width of the upper outer ring fire hole 6; the height of the upper ignition hole 7 is smaller than the height of the upper outer ring fire hole 6; this structure reduces the gas flow cross-sectional area of the upper ignition hole 7, and the small amount of gas ejected can meet the ignition needs, avoiding a large fire burning the ignition needle for a long time.

[0032] The ignition distributor 2 includes an ignition base 8 and an ignition cover 9. The ignition cover 9 is arranged on the upper side of the ignition base 8. The ignition zone A is arranged on the ignition base 8, and a first groove 801 is provided on the inner side of the ignition zone A. The bottom surface of the ignition cover 9 is provided with a first protrusion 901 that forms a fool-proof fit with the first groove 801.

[0033] During installation, a connecting ear 85 is extended laterally from the inner wall of the fire distributor seat 8, and a connecting hole 851 is opened on the connecting ear 85. A connecting column 93 is extended from the bottom surface of the fire distributor cover 9 corresponding to the connecting hole. A fastening unit such as a screw is passed through the connecting hole 951 and the connecting column 93 to achieve a fastening connection between the fire distributor cover 9 and the fire distributor seat 8.

[0034] An ignition needle 10 is installed on the side of the burner seat 1, and a protective cover 11 is connected to the ignition cover 9. The protective cover 11 extends outward to the upper side of the ignition needle 10, and a protective cover avoidance recess B is opened on the ignition seat 8 corresponding to the ignition interval A; the first groove 801 and the first protrusion 901 are used to limit the installation of the ignition seat 8 and the ignition cover 9 in the specified position, ensuring that the protective cover 11 can correspond to the protective cover avoidance recess B.

[0038] The central protrusion of the fire-distributing cover 9 is provided with a truncated cone structure 91 , and the side surface of the truncated cone structure 91 is inclined along the circumferential direction to open a plurality of inner ring fire holes 902 connected to the inner ring gas mixing chamber 4 ; this structure enables the burner to have an intermediate flame.

[0039] An air intake channel 12 is provided at the center of the frustum structure 91, and an air baffle 13 is connected to the upper side of the air intake channel 12 through a number of supporting legs 131. The air baffle 13 and the cover surface of the fire distribution cover 9 are spaced apart to form an air intake gap C; the air intake channel 12 can increase the secondary supply of air, so that the flame of the inner ring fire hole 902 can burn more fully, improve thermal efficiency, and effectively reduce the smoke generated during combustion. The air intake gap C formed by the air baffle 13 can evenly disperse the air to the surroundings.

[0040] The diameter of the air baffle 13 is greater than or equal to the diameter of the air intake channel 12, which can effectively prevent oil and food from splashing into the air intake channel 12 during cooking, and play a role in preventing dust, insects and water, thereby improving the cleanliness of the burner.

The outer portion of the separator ring 84 and the outer ring groove 101 enclose and limit the outer ring gas mixing chamber 3, and the inner portion of the separator ring 84 and the inner ring groove 102 enclose and limit the inner ring gas mixing chamber 4.

[0044] A connecting sleeve 92 connected to the central channel 103 extends downward from the center of the ignition cover 9 , and the inner cavity of the connecting sleeve 92 and the central channel 103 form an air intake channel 12 .

[0045] A second groove 104 is provided on the inner groove wall of the outer ring groove 101, and a second protrusion 804 is provided on the outer side surface of the separating ring 84 to form a fool-proof fit with the second groove 104; the second groove 104 and the second protrusion 804 are used to ensure that the ignition interval A and the ignition needle 10 can be set correspondingly, and the outer part of the separating ring 84 is set correspondingly to the outer ring groove 101, and the inner part of the separating ring 84 is set correspondingly to the inner ring groove 102.
