The invention can also adjust the air inflow of secondary air needed by the main fire hole 21 communicated with the outer ring air mixing chamber 1, the outer peripheral wall of the annular cavity 52 is downwards protruded to form a circle of convex wall 521, and an adjusting piece capable of adjusting the relative distance between the air inlet 32 of the secondary air supplementing small chamber 3 and the liquid containing disc 4 is arranged on the convex wall 521. From the viewpoint of simple installation, it is preferable that the adjusting member includes an adjusting plate 8 which is movable up and down with respect to the convex wall 521, and the adjusting plate 8 includes a first annular ring 81 and a second annular ring 82 which are provided at an inner and outer interval, and at least one radially provided connecting rib 83 which connects the first annular ring 81 and the second annular ring 82. While the distance between the air inlet 32 of the secondary air supplementing small chamber 3 and the liquid containing disc 4 can be adjusted by the adjusting piece, the phenomenon that the overflow liquid enters the air inlet 32 of the secondary air supplementing small chamber 3 can be prevented, the overflow liquid is prevented from blocking the air inlet 32 of the secondary air supplementing small chamber 3, a baffle plate 821 is partially and upwardly extended between the adjacent transmission channels 7 at the inner side edge 822 of the second annular ring 82, a gas supplementing cavity 9 is formed between the inner ring gas mixing chamber 5 and the outer ring gas mixing chamber 1, the baffle plate 821 extends into the gas supplementing cavity 9 and can at least partially cover the inner wall surface of the inner annular wall 11, a through hole 84 for communicating the gas supplementing cavity 9 with the air below the liquid containing disc 4 is formed between the outer side of the first annular ring 81, the inner side of the second annular ring 82 and the adjacent connecting ribs 83, and the outer side edge 823 of the second annular ring 82 extends horizontally below the outer ring gas mixing chamber 1 and is opposite to the air inlet 32 of the secondary air supplementing small chamber 3. Since the baffle 821 of the regulating member is limited by the above-mentioned transmission channel 7, in order to better realize the change of the relative distance between the air inlet 32 of the secondary air supplementing small chamber 3 and the liquid containing disc 4, the regulating member further comprises an actuating member capable of driving the regulating plate 8 to move up and down relative to the convex wall 521, and the regulating plate 8 is driven to move relatively in an up-and-down or rotating manner by being matched with the convex wall 521 formed by the downward bulge of the outer peripheral wall of the annular cavity 52 through an independent actuating member. Preferably, the adjustment plate 8 passes through said convex wall 521 by means of a first annular collar 81 and rests on the actuator. Still more preferably, the actuating member is a collar 10 screwed to the outer wall surface of the flange 521, and the adjusting plate 8 can move up and down only with respect to the liquid containing plate 4 under the restriction of the transfer passage 7 in a state where the collar 10 rotates with respect to the flange 521. Finally, in order to achieve the convenience of installation of the ignition needle and the thermocouple, the outer wall of the first annular ring 81 is provided with a first semi-closed groove 811 and a second semi-closed groove 812 which are distributed in two opposite directions, and the ignition needle and the thermocouple installed on the base 6 respectively pass through the corresponding parts of the base 6 upwards and extend into the corresponding first semi-closed groove 811 and the corresponding second semi-closed groove 812.
