[0022] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, electrical connections, or mutual communication; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the following embodiments and accompanying drawings specifically illustrate the air gun device with independently adjustable flow of the present invention.

[0024] Figure 1 It is a structural schematic diagram of an air gun device capable of independently adjusting flow rate in an embodiment of the present utility model. Figure 2 It is a three-dimensional cross-sectional view of an air gun device capable of independently adjusting flow rate in an embodiment of the present utility model. Figure 3 It is a front cross-sectional view of an air gun device capable of independently adjusting flow rate in an embodiment of the present utility model.

[0025] like Figure 1-3 As shown, the air gun device 100 capable of independently adjusting flow in this embodiment includes a fixing member 10 , an adjusting member 20 , an air inlet pipe 40 , a burner air ring 50 and an O-ring 30 .

[0026] The burner air ring 50 is an annular hollow structure with a rectangular cross-section. The annular hollow structure includes a front plate 51 and a rear plate 52. A first through hole 53 and a second through hole 54 are respectively opened at corresponding positions of the front plate 51 and the rear plate 52. The first through hole 53 on the front plate is used for welding the fixing part 10, and the second through hole 54 on the rear plate is used for welding the intake pipe 40. Thus, the relative positions of the fixing part 10, the burner air ring 50 and the intake pipe 40 are fixed, and the gas can enter the interior of the intake pipe 40 through the burner air ring 50.

[0027] Figure 4 It is a structural schematic diagram of a fixing member in an embodiment of the present utility model.

[0033] The air intake pipe 40 is a hollow cylinder and is arranged on one side of the adjusting member 20. The side of the adjusting member 20 close to the second threaded structure 21 is a conical structure 23. The position of the air intake pipe 40 corresponds to that of the adjusting member 20, so that the front end of the conical structure 23 can extend into the air intake pipe 40. The user controls the size of the adjusting member 20 extending out of the fixing member 10 by adjusting the screwing length of the threaded connection between the fixing member 10 and the adjusting member 20. The distance between the end of the adjusting member 20 and the inlet end of the air intake pipe 40 changes, thereby controlling the air intake amount of the air intake pipe 40.

[0034] The design of the conical structure 23 further enhances the adjustment accuracy, and the angle of the fluid is more reasonable, avoiding problems such as irregular airflow and vortex.

[0035] Usage process:

[0036] The adjusting member 20 is rotated to change the relative position of the adjusting member 20 and the air intake pipe 40 , thereby controlling the air intake amount of the air intake pipe 40 .
