As shown in fig. 8, the sub nozzle 3 includes a sub nozzle 31 and a sub flap 32, the sub nozzle 31 is connected to the main body assembly 1, one end of the sub nozzle 31 communicates with the sub intake passage 15, and the other end communicates with the sub injection pipe 302 through a sub communication hole 3022. The secondary baffle 32 is provided with a second air inlet 321, and the second air inlet 321 is opposite to the secondary air injection port 3021. That is, the fuel gas in the sub-intake passage 15 enters the sub-injection pipe 302 through the sub-nozzle 31, and the outside air enters the sub-injection pipe 302 through the second air inlet 321 and the sub-air inlet 3021 in this order, so that the fuel gas and the air are mixed in the sub-injection pipe 302.

Preferably, as shown in fig. 8, the secondary nozzle 3 further includes a second elastic member 33, where the second elastic member 33 is connected between the secondary nozzle 31 and the secondary baffle 32, and the second elastic member 33 makes the secondary baffle 32 press against an end portion of the secondary injection pipe 302, so that the secondary baffle 32 can tightly seal the periphery of the secondary communication hole 3022, thereby avoiding gas leakage.

Since the gas quantity injected by the main nozzle 2 into the main injection pipe 301 is larger than the gas quantity injected by the auxiliary nozzle 3 into the auxiliary injection pipe 302, in order to ensure that the mixing proportion of the gas and air in the outer ring mixing cavity and the inner ring mixing cavity is consistent, the main injection pipe 301 needs to enter more air than the auxiliary injection pipe 302. In this regard, as shown in fig. 8, a third air inlet 211 is provided on the outer peripheral surface of the main nozzle 21, and the third air inlet 211 communicates the outside atmosphere with the inside of the main nozzle 21. When the high-speed fuel gas flows into the main nozzle 21, the air pressure in the main nozzle 21 is smaller than the external atmospheric pressure, so that the external air can enter the main nozzle 21 through the third air inlet 211, thereby increasing the proportion of the air entering the main injection pipe 301 and further ensuring that the air and the fuel gas in the outer ring mixing cavity have a better mixing proportion.
