[0019] As Figures 1 to 5 shown in the figure, the utility model includes a cylinder 1 provided with a gas inlet pipe 10, a flipping assembly movably connected to one end of the cylinder 1, and a support assembly connected to the other end of the cylinder 1. An adjusting mechanism for adjusting the gas output is provided at the gas outlet end of the gas inlet pipe 10. During use, the cylinder 1 is supported by the support assembly, and then the flipping assembly drives the cylinder 1 to flip around the support point between the support assembly and the cylinder 1 as the center of the circle, synchronously driving the adjusting mechanism to flip, so as to adjust the use angle of the gas flame.

[0020] Specifically, the flipping assembly includes a support plate 20 fixed on a bracket 2, a reciprocating motor 21 fixed on the support plate 20, a lead screw 22 connected to the output end of the reciprocating motor 21, and a fixed block 23 screwed to the lead screw 22. The fixed block 23 is screwed to one end of a rocker 24, and the other end of the rocker 24 is screwed to the outer side wall of the cylinder 1.

[0021] The support assembly includes a collar 25 fixedly connected to the outer side wall of the cylinder 1. A flange sleeve 26 fixedly connected to the inner side wall of the combustion chamber is sleeved outside the collar 25. The hole walls at the left and right ends of the middle hole of the flange sleeve 26 are adaptively abutted against the outer side walls at the corresponding positions of the collar 25, so that the collar 25 can flip in the front and rear directions in the middle hole of the flange sleeve 26. Among them, the flange sleeve 26 is fixedly connected by screwing an upper clamping ring 261 and a lower clamping ring 262. The upper clamping ring 261 and the lower clamping ring 262 enclose a frame structure containing a middle hole. In this frame structure, there is a collar 25 formed by screwing a left clamping ring 251 and a right clamping ring 252. One side of the cylinder 1 passes through the collar 25.

[0022] The adjusting mechanism includes a nozzle 27 sleeved at the gas outlet end of the gas inlet pipe 10. A tapered hole 271 communicating with the gas inlet pipe 10 is provided on the nozzle 27. A mixed-flow disk 3 is screwed on the nozzle 27. A plurality of mixed-flow through holes 33 are arranged around the circumference of the mixed-flow disk 3. A threaded sleeve 31 is fixedly provided in the middle of the mixed-flow disk 3. A tapered block 32 is screwed on the threaded sleeve 31. The small-diameter end of the tapered block 32 extends into the tapered hole 271.

[0023] A plurality of spiral air channels 272 are arranged on the hole wall of the tapered hole 271 along the circumference.

[0024] The working principle of the utility model is as follows:

[0025] As Figures 1 to 5As shown, during normal use, the gas inlet pipe 10 is opened to discharge gas into the combustion chamber (not labeled). The gas is discharged through the conical hole 271. While discharging, due to flowing through a plurality of spiral air ducts 272 arranged in the circumferential direction (such as Figure 3 the state shown), the gas forms a spiral shape in the gas outlet direction, facilitating rapid mixing with air to improve the combustion efficiency.

[0026] When the flame spraying angle needs to be adjusted, the reciprocating motor 21 is started, driving the fixed block 23 to horizontally move along the axial direction of the lead screw 22, and driving the articulated rocker 24 to rotate. Synchronously, the air cylinder 1 articulated to the other end of the rocker 24 starts to flip. The outer side of the air cylinder 1 is sleeved with a collar 25, and a flange sleeve 26 is also sleeved on the outer side of the collar 25. The hole walls at the left and right ends of the middle hole of the flange sleeve 26 are adaptively abutted against the outer side walls at the corresponding positions of the collar 25, so that the collar 25 can flip in the front and rear directions within the middle hole of the flange sleeve 26. Therefore, in the rotating state of the rocker 24, the whole air cylinder 1 is driven to flip in the front and rear directions (i.e., Figure 1 perform clockwise or counterclockwise flipping in the vertical direction shown).

[0027] It should be noted that the flange sleeve 26 is fixedly connected by screwing the upper clamping ring 261 and the lower clamping ring 262. The upper clamping ring 261 and the lower clamping ring 262 enclose a hollow frame structure. In this frame structure, there is a collar 25 fixedly connected by screwing the left clamping ring 251 and the right clamping ring 252. One side of the air cylinder 1 passes through the collar 25.

[0028] In addition, when the gas discharge amount needs to be adjusted, before use, the screwed conical block 32 is twisted to adjust the length of the conical block 32 extending into the conical hole 271, so as to adjust the gap between the hole wall of the conical hole 271 and the outer side wall of the conical block 32, realizing the adjustment of the gas discharge amount to meet the requirements of the "W" - shaped combustion mode in the combustion chamber.
