Description

Technical Field

[0001] This invention relates to the field of flamethrower technology, and more particularly to a flamethrower nozzle. Background Technology

[0002] In the aluminum profile processing, long aluminum rods are first fed into a kiln for heating, then cut into several segments using a hydraulic press, and finally extruded into aluminum profiles. During extrusion, a pusher is used to press the end of the aluminum rod into the mold. Because the aluminum rod is nearly molten after heating, the pusher easily sticks to the end of the rod. Therefore, a flame gun is used to scorch the end face of the aluminum rod, completely oxidizing it to reduce adhesion. There is a time interval between scorching one aluminum rod and scorching the next; the flame gun does not need to be constantly burning. However, existing flame guns, if the air velocity is too high, may fail to form a flame or extinguish due to the flame being too far from the nozzle, resulting in unstable flames and inconvenient operation. Summary of the Invention

[0003] The purpose of this invention is to provide a flame gun nozzle to solve the problems of unstable flame and inconvenient operation.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A flamethrower nozzle includes a connecting end and a nozzle end connected together. The connecting end is provided with an air inlet channel. The nozzle end is provided with an air inlet chamber, an air outlet, an air outlet chamber, an air storage chamber, a first connecting channel, and a second connecting channel. One end of the air inlet chamber is connected to the air inlet channel, and the other end of the air inlet chamber is connected to one end of the air outlet. The other end of the air outlet is connected to the air outlet chamber. The air storage chamber is connected to the air inlet chamber through the first connecting channel, and the air storage chamber is connected to the air outlet chamber through the second connecting channel.

[0006] Furthermore, the nozzle end is also provided with a flame nozzle, one end of which is connected to the gas outlet chamber, and the other end of which gradually expands into a trumpet shape and penetrates the end of the nozzle. This gradual expansion into a trumpet shape allows the arriving combustible gas mixture to diffuse in all directions, coming into contact with more air and burning more completely, thus resulting in a higher flame temperature, shorter time required to scorch the end face of the aluminum rod, and higher scorching efficiency.

[0007] Furthermore, the air intake channel is funnel-shaped and gradually narrows towards one end of the air intake chamber. This increases the flow velocity of the combustible gas mixture reaching the air intake chamber. As the combustible gas mixture is compressed as it passes through the air intake channel, it exits the air outlet chamber at a higher velocity. Under the same air pressure, a higher exhaust velocity can be achieved, thereby enabling the flame to burn more intensely.

[0008] Furthermore, the gas storage chamber is a closed annular cavity. Therefore, the gas storage chamber can store a certain amount of combustible gas mixture.

[0009] Furthermore, the first connecting channel is configured as multiple channels arranged around the intake chamber. Thus, the combustible gas mixture in the intake chamber can enter the storage chamber through the first connecting channel.

[0010] Furthermore, the second connecting channel is configured as multiple channels arranged around the outlet chamber. Thus, the combustible gas mixture in the storage chamber can enter the outlet chamber through the second connecting channel.

[0011] Furthermore, the second connecting channel is perpendicular to the side wall of the gas outlet chamber, and an vent is formed at the connection between the second connecting channel and the gas outlet chamber. The vents are evenly distributed on the side wall of the gas outlet chamber. Thus, the evenly distributed vents allow the combustible gas mixture in the gas storage chamber to escape evenly into the gas outlet chamber.

[0012] Furthermore, the vent includes a main vent and secondary vents, with one main vent and multiple secondary vents arranged around the main vent. Therefore, providing multiple secondary vents allows for a more uniform flow of the combustible mixture into the venting chamber while maintaining the gas flow rate.

[0013] One of the above technical solutions has the following beneficial effects:

[0014] By incorporating a gas storage chamber at the nozzle end, when the flamethrower nozzle is in operation, the combustible gas mixture enters the nozzle end from the connecting end and is then ejected for combustion. Simultaneously, the combustible gas mixture enters the gas storage chamber through the first connecting channel and is then radially output to the outlet chamber through the second connecting channel. The radially output gas pressure can, to a certain extent, slow down the velocity of the gas mixture ejected from the outlet, preventing the flame from extinguishing due to excessive distance from the nozzle, thus stabilizing the flame. Furthermore, because the second connecting channel provides radial gas output, it maintains a flame within the flamethrower nozzle, effectively preventing the nozzle from extinguishing.

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] This embodiment discloses a flamethrower nozzle, such as Figures 1-3As shown, the device includes a connecting end 1 and a nozzle end 2, with the connecting end 1 and nozzle end 2 threadedly connected. One end of the connecting end 1 is connected to the body of the flamethrower, and the other end of the connecting end 1 has an internal thread 12. One end of the nozzle end 2 has an external thread 29 that mates with the internal thread 12. The connecting end 1 has an air intake channel 11 that extends through it, and the air intake channel 11 is shaped like a funnel that gradually narrows towards the nozzle end 2. When the gas passes through the gradually narrowing funnel-shaped air intake channel 11, the gas velocity increases rapidly, forming a jet when it passes through the nozzle end 2, which can make the flame burning at the nozzle end 2 more intense.

[0025] The nozzle end 2 has a cylindrical structure, and inside it are an air inlet chamber 21, an air outlet 22, an air outlet chamber 23, an air storage chamber 24, a first connecting channel 25, a second connecting channel 26, and a flame nozzle 27. One end of the air inlet chamber 21 is connected to and communicates with the air inlet channel 11, and the other end of the air inlet chamber 21 is connected to one end of the air outlet 22. The other end of the air outlet 22 is connected to the air outlet chamber 23. The air inlet chamber 21, the air outlet 22, the air outlet chamber 23, and the flame nozzle 27 are sequentially connected and pass through the center of the nozzle end 2. The air storage chamber 24 is a closed annular cavity surrounding the air inlet chamber 21, the air outlet 22, and the air outlet chamber 23. The air storage chamber 24 is connected to the air inlet chamber 21 through the first connecting channel 25, and the air storage chamber 24 is connected to the air outlet chamber 23 through the second connecting channel 26.

[0026] One end of the nozzle 27 is connected to the exhaust chamber 23, and the other end of the nozzle 27 gradually expands into a trumpet shape and penetrates the end of the nozzle 2. The trumpet-shaped nozzle 27 allows the ejected combustible mixture to diffuse in all directions and come into full contact with the air, resulting in more complete combustion and higher burning efficiency.

[0027] Multiple first connecting channels 25, preferably four, are arranged evenly around the air intake chamber 21. Ten to twelve second connecting channels 26 surround the air outlet chamber 23, and the diameter of the second connecting channels 26 is smaller than the diameter of the first connecting channels 25. The second connecting channels 26 are perpendicular to the sidewall of the air outlet chamber 23, and an vent 28 is formed at the connection point between the second connecting channel 26 and the air outlet chamber 23. The vents 28 are evenly distributed on the sidewall of the air outlet chamber 23.

[0028] The vent 22 includes a main vent 221 and a secondary vent 222, both of which are circular holes. There is one main vent 221 and 10 to 12 secondary vents 222 evenly arranged around the main vent 221. The diameter of the main vent 221 is larger than the diameter of the secondary vents 222.

[0029] The nozzle of this invention is installed at one end of the outlet of the flamethrower body, and one end of the inlet of the flamethrower body is connected to the gas supply device. When the flamethrower nozzle is performing flamethrowing operations, the gas supply device supplies combustible gas to the flamethrower body through one air inlet. The combustible gas mixes with air or oxygen supplied into the flamethrower body from the other air inlet to form a combustible mixture. The combustible gas mixture flows in from the intake channel 11 at the connecting end 1 and is compressed and accelerated by the intake channel 11 before entering the intake chamber 21 at the nozzle end. It then flows through the outlet hole 22 to the outlet chamber 23 and is ejected to the flame nozzle 27 for combustion. The intake channel is funnel-shaped and gradually narrows towards one end of the intake chamber, which increases the flow velocity of the combustible gas mixture passing through the intake chamber. When the combustible gas mixture passes through the intake channel 11, it is compressed, and the flow velocity is even higher when the combustible gas mixture is ejected from the outlet chamber 23. Under the same air pressure, a higher exhaust velocity can be achieved, which allows the flame to burn more intensely. At the same time, the combustible gas mixture enters the gas storage chamber 24 through the first connecting channel 25, filling the gas storage chamber 24, and then is ejected from the second connecting channel 26, which keeps the flame in the flame nozzle 27 and prevents the flame from going out due to being too far from the nozzle, thus stabilizing the flame.
