[0037] Referring to Figure 1 and Figure 3 The preferred embodiment of the spray gun provided by the present application comprises:

[0038] A base 10 is made of metal material, in this embodiment, an aluminum alloy, and the alloy material used can be adjusted according to requirements. The base 10 is integrally formed with a gas chamber 11 in the center. The use of metal material can strengthen the overall pressure resistance, and there is no need to additionally provide a plastic gas cylinder. The base 10 is provided with an injection port 12 at the bottom and an outlet 13 at the top. The base 10 is made of aerospace aluminum alloy, and the center of gravity is arranged at the 2 / 3 position of the base 10. The outer side of the base 10 is designed in a curve, so that the user can hold it in an ergonomic manner. The injection port 12 can provide gas injection into the gas chamber 11, and the gas can be discharged from the outlet 13. The bottom of the base 10 is further provided with an anti-skid rubber pad 14. The anti-skid rubber pad 14 can increase the stability of the base 10, ensure that it is not easy to slide on any material, and increase the safety of use. In addition, in order to control the size of the gas output of the outlet 13, the base 10 is further provided with a gas adjustment knob 15. By rotating the knob, the gas output of the outlet 13 can be controlled.

[0039] A ignition button 20 is made of metal material in this embodiment, and is arranged at the top of the base 10. The ignition button 20 has a pressing portion 21. The pressing portion 21 can selectively open the outlet 13. The top surface of the pressing portion 21 is designed in a curve, which can provide a smooth feeling when the user presses it, and it is easy to exert force on the pressing portion 21. The ignition button 20 is further provided with a safety switch 22. The safety switch 22 can selectively abut against the pressing portion 21. When the pressing portion 21 is abutted by the safety switch 22, the pressing portion 21 cannot be actuated, which ensures safety in use. The safety switch 22 can be actuated before the pressing portion 21 is actuated, which can avoid accidental touch of the pressing portion 21. In addition, when the safety switch 22 is actuated after the pressing portion 21 is pressed, the pressing portion 21 can remain in the pressed state, so that the outlet 13 can be continuously opened to output gas, that is, the state of holding ignition.

[0040] A gun part 30, in this embodiment, is made of the same metal material as the base 10, is arranged above the base 10 and adjacent to the ignition button 20, and is provided with a piezoelectric ignition element 31, a ceramic nozzle 32, an air inlet 33, and an outlet 34. The piezoelectric ignition element 31 is connected to the pressing part 21 of the ignition button 20 and can be triggered by the pressing part 21 to ignite. The piezoelectric ignition element 31 is provided with an ignition wire 311 arranged in the ceramic nozzle 32 and close to the outlet 34, and a power connection wire 312 arranged on the side of the ceramic nozzle 32. When the piezoelectric ignition element 31 is triggered, the ignition wire 311 will conduct electricity and generate sparks to ignite the gas, and the current generated by the ignition wire 311 will be guided back into the piezoelectric ignition element 31 through the power connection wire 312, avoiding the conduction of the metal material of the gun part 30 or the ignition button 20 or the base 10. When the piezoelectric ignition element 31 ignites, the pressing part 21 will also open the outlet 13, allowing the combustible gas in the gas container 11 to be guided out of the outlet 13 and ignited by the ignition wire 311 of the piezoelectric ignition element 31 at the position of the ceramic nozzle 32, forming a flame inside the ceramic nozzle 32. The ceramic nozzle 32 is arranged at the outlet 34, which can ensure the stability of the flame and reach a very high temperature of up to 1300℃, making it fast and efficient to ignite a cigar. The inlet 33 is connected to the outlet 13, allowing the combustible gas and oxygen to mix well. The inlet 33 is arranged on both sides of the gun body 30 and forms two inclined air inlets 331, which can improve air intake efficiency through the design of the inclined angle. The outlet 34 is also made of aluminum alloy, which can form a heat storage effect to prevent the flame from being extinguished due to shaking. The outlet 34 is provided with a guide cone 341 to maximize the output efficiency of the flame. In addition, the gun body 30 is provided with a flame adjustment knob 35 at the top, which can adjust the flow of air introduced by the air inlet 33, control the mixing ratio between gas and air, control the intensity of the flame, and switch between soft and hard flames. In addition, the length of the flame can be adjusted between 1-6 cm by switching the gas adjustment knob 15.

[0041] When using the spray gun, the base 10 can be held by the hand, and the thumb is arranged on the pressing part 21, which can be held and pressed in an ergonomic way. At the same time, the hardness of the flame can be adjusted by the flame adjustment knob 35, and the size of the flame can be adjusted by the gas adjustment knob 15. In addition, a powerful, uniform, and efficient flame can be generated by the design of the air inlet 33, the ceramic nozzle 32, and the outlet 34.

[0042] The above is only a feasible embodiment of the present application, and cannot limit the scope of the present application; that is, any equivalent changes and modifications made within the scope of the present application claims should still be within the scope of the present application patent.

[0043] Of course, the present application can also have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application, but these corresponding changes and modifications should all be within the protection scope of the present application claims.
