In order to reduce the actual operation difficulty of a user, as shown in fig. 10, the air inlet adjusting part 16 is provided with a sliding part 164, at least one of the distributor 11 and the injection pipe 13 is provided with a guiding part 117, referring to fig. 11, the guiding part 117 is arranged on the injection pipe 13, the guiding part 117 extends along the axial direction of the air inlet 130 of the injection pipe 13, the sliding part 164 is connected with the guiding part 117 and can slide along the extending direction of the guiding part 117, and the injection pipe 13 is connected with the air inlet adjusting part 16, so that the air inlet adjusting part 16 can slide along the extending direction of the guiding part 117 on the injection pipe 13, and the sliding part 164 is matched with the guiding part 117 to adjust the distance between the nozzles 12 of the air inlet adjusting part 16, thereby changing the air inlet area of the high-speed gas injected air injected by the nozzles 12, and further adjusting the air inlet amount. Thus, the structure of the air inlet adjusting piece 16 is simpler, and the maintenance and repair of the gas stove 1 are convenient.

On the basis, referring to fig. 12, the sliding portion 164 is a protruding portion, the guiding portion 117 is a recessed portion, the sliding portion 164 is fitted in the guiding portion 117, the protruding portion can slide along the extending direction of the recessed portion, and the air inlet area of the high-speed gas injected air ejected from the nozzle 12 is changed to adjust the amount of injected air through the sliding of the protruding portion; or, referring to fig. 13, the sliding portion 164 is a concave portion, the guiding portion 117 is a convex portion, the guiding portion 117 is fitted in the sliding portion 164, the concave portion can slide along the extending direction of the convex portion, and the air intake area of the high-speed gas ejected from the nozzle 12 is changed to adjust the amount of ejected air by sliding the concave portion.

Thus, the intake air adjusting member 16 can be adjusted more conveniently, and the user can adjust the intake air by sliding the sliding portion 164 as needed, thereby obtaining the optimal combustion effect.

As shown in fig. 14, the central axis of the first ejector pipe 131 is vertically arranged on the central axis of the first annular chamber 110, the first nozzle 121 is coaxially arranged with the first ejector pipe 131, and the first nozzle 121 supplies air to the inner fire cover 101 separately. The second induction pipe 132 is horizontally arranged with the second nozzle 122 (refer to fig. 8), is connected with the premixing member 113, is communicated with the second annular chamber 111 through the premixing chamber 114, and supplies air to the outer fire cover 102 through the second nozzle 122.

It can be understood that the gas supply of the inner fire cover 101 and the outer fire cover 102 are not affected, when the power of the inner fire cover 101 is required to be increased, the size of the first annular cavity 110 can be increased, and the size of the inner fire cover 101 is correspondingly increased; when the power of the inner fire cover 101 is required to be reduced, the size of the first annular cavity 110 can be reduced, and the size of the inner fire cover 101 is correspondingly reduced; similarly, when the power of the outer fire cover 102 is required to be increased, the size of the second annular cavity 111 can be increased, and the size of the outer fire cover 102 is correspondingly increased; when the power of the outer fire cover 102 is required to be reduced, the size of the second annular cavity 111 can be reduced, and the size of the outer fire cover 102 is correspondingly reduced; when the volume requirement needs to be met, the sizes of the inner fire cover 101 and the outer fire cover 102 can be designed in a combined manner, so that the gas stove 1 can meet the power requirement while meeting the volume requirement. Therefore, the structure can be reasonably designed according to the requirement of combustion power, so that the structure of the gas stove 1 is more compact, and multiple power requirements can be simultaneously realized in a small volume.

For the outer fire cover 102, because the circumference is too long, the second ejector pipes 132 are arranged in a plurality of numbers, the second ejector pipes 132 are arranged at intervals along the circumference of the second annular cavity 111, the second ejector pipes 132 are connected with the premixing part 113 and communicated with the second annular cavity 111 through the premixing cavity 114, mixed gas is simultaneously conveyed to the distributor 11 through the second ejector pipes and enters the premixing cavities 114, a large number of mixed gas enters the second annular cavity 111 from the premixing cavities 114 and is distributed at intervals along the circumference of the second annular cavity 111, so that the mixed gas is uniformly distributed in the second annular cavity 111, and a large number of mixed gas can be rapidly and uniformly sprayed out from the fire holes 103 in the outer fire cover 102.

It can be understood that the number of the second nozzles 122 is multiple, the multiple second nozzles 122 and the multiple second induction pipes 132 are arranged in a one-to-one correspondence manner, and the multiple second induction pipes 132 and the multiple second nozzles 122 are all arranged at intervals along the circumferential direction of the second annular cavity 111, wherein the outlet directions of the multiple second induction pipes 132 are consistent, that is, the outlets of the multiple second induction pipes 132 are all opened along the clockwise direction or the counterclockwise direction. So, the mist draws the pipe 132 from the second and follows clockwise or anticlockwise entering second annular chamber 111, and the export direction that the pipe 132 was drawn to a plurality of seconds is unanimous, make a plurality of seconds draw the mist in the pipe 132 to jet out to second annular chamber 111 along same direction, can make mist fast distribution in whole second annular chamber 111, thereby the mist is from the more even blowout of outer fire lid 102, can make the burning more even.
