The utility model discloses the theory of operation:

when the air duct for the long open fire 1 needs to be opened, the handle 8 is manually pressed downwards, meanwhile, the first shaft 71 moves downwards, the limiting slide block 711 of the first shaft 71 moves to the bottom surface of one end of the A sliding groove 741, then the handle 8 rotates ninety degrees anticlockwise, the first half gear 72 rotates to act on the first gear 5, and therefore the valve 3 for the long open fire is acted on the air duct for the long open fire 1 through the first gear 5; as shown in fig. 5, the limiting slider 711 moves into the B chute 742 and is attached to a side wall surface of the lower end of the B chute 742, the side of the lower end of the B chute 742 blocks the limiting slider 711 from moving further, the handle 8 is released, and the spring 75 drives the shaft i 71 to return upwards through the abutting plate 76, so as to prompt the pilot fire valve 3 to open the pilot fire air duct 1 at the moment and prevent the pilot fire air duct 2 from being opened due to over-rotation when the pilot fire air duct 2 does not need to be opened; the ignition microswitch 9 is triggered in the process that the half gear 72 moves downwards along with the first shaft 71 and rotates, so that the igniter is controlled to ignite the gas discharged from the long open flame gas pipeline 1; as shown in fig. 6, after the half gear 72 rotates ninety degrees along with the first shaft 71, the half gear 72 is not meshed with the first gear 5 and the second gear 6, and when the limit slider 711 moves horizontally in the range of the B chute 742, the half gear 72 is not meshed with the first gear 5 and the second gear 6;

when the main fire air duct 2 needs to be opened, as shown in fig. 7, the handle 8 is manually rotated anticlockwise, the half gear 72 is meshed with the second gear 6 and rotates the second gear 6, so that the main fire valve 4 opens the main fire air duct 2, the length of the C chute 743 is one time of the A chute 741, so that the half gear 72 can rotate one hundred eighty degrees, the acting number of turns of the half gear 72 on the second gear 6 is greater than that of the first gear 5, so that the half gear 72 adjusts the air supply quantity of the main fire air duct 2 through the main fire valve 4, for example, the existing mode rotates ninety degrees to be maximum fire power, and continues to rotate ninety degrees to be minimum fire power;

when the main fire air duct 2 needs to be closed, the handle 8 is turned clockwise until the limiting slide block 711 moves to be attached to the other side wall surface at the upper end of the B chute 742, and the purpose of the handle is to prompt that the main fire valve 4 closes the main fire air duct 2 at the moment;

when the air duct 1 for long open fire needs to be closed, as shown in fig. 8, the handle 8 is manually pressed down, the limiting slider 711 is limited by the partition plate 741-1, the limiting slider 711 moves down to the middle of the a chute 741, the handle 8 rotates clockwise by ninety degrees, the limiting slider 711 returns to the initial position of the a chute 741, the purpose of limiting the downward movement of the limiting slider 711 through the partition plate 741-1 is that the wall face half gear 72 is pressed down again to trigger the ignition microswitch 9, and the igniter is caused to discharge by mistake.
