Description

Technical Field

[0001] The utility model relates to the technical field of flamethrowers, in particular to a gas flow regulating component for a flamethrower. Background Art

[0002] The flamethrower, as one of the outdoor products that has attracted much attention in recent years, has not only enriched the diversity of outdoor life, but also become an indispensable member of outdoor cooking utensils. Abroad, it is often called "TORCH", which implies its powerful flame power and versatility. This flamethrower cleverly uses the existing butane gas tank as energy and transforms it into an efficient and convenient ignition and heating tool through precise design.

[0003] During the use of a flamethrower, one of its core functions is to precisely control the delivery and preheating of gas through a gas flow regulating assembly to ensure flame stability and safety. However, many flamethrowers on the market are currently equipped with gas flow regulating assemblies that usually adopt an integrated design. Although this design is compact in structure, it brings some inconveniences during actual use. Specifically, when the regulating valve in the gas flow regulating assembly has problems due to long-term use or improper operation, users often need to replace the entire gas flow regulating assembly. This design not only increases maintenance costs, but also reduces the convenience of use, because users may need to wait for the arrival of new components or seek professional maintenance services.

[0004] Therefore, it is necessary to provide a new flamethrower gas flow regulating assembly to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a gas flow regulating assembly for a flamethrower.

[0006] The gas flow regulating assembly of a flamethrower provided by the utility model comprises: a gas delivery shell and a gas regulating shell, wherein the interior of the gas delivery shell is used to deliver gas, and the gas regulating shell is located above the gas delivery shell; a slide rod mechanism, wherein the slide rod mechanism is installed inside the gas delivery shell and is used to control the passage of gas, and the slide rod mechanism comprises an injection pipe, a movable rod and a first screw rod.

[0007] When gas needs to be supplied to the flamethrower, the slide rod mechanism inside the gas delivery shell is rotated. The slide rod mechanism no longer blocks the discharge port of the gas delivery shell, facilitating the normal passage of gas. The internal mechanism of the gas regulating shell can control the flow of gas.

[0008] Preferably, an injection pipe is fixedly connected to the inner wall of the inlet of the gas delivery shell, a movable rod is slidably installed on the inner wall of the gas delivery shell, and the movable rod is located below the outlet of the gas delivery shell, the inner wall of the gas delivery shell is rotatably connected to a first screw rod, and the threaded surface of the first screw rod is meshed with the inner wall of the circular groove of the movable rod, and the first screw rod is fixedly connected to a first rotor on the side away from the gas delivery shell.

[0009] When the gas enters the inner wall of the gas delivery shell through the injection pipe, the first wheel is rotated to drive the first screw rod to rotate on the inner wall of the gas delivery shell. The threaded surface of the first screw rod contacts the inner wall of the circular groove of the movable rod, and the movable rod is moved away from the discharge port of the gas delivery shell to facilitate the passage of gas.

[0010] Preferably, a guide seat is fixedly connected to the upper surface of the gas delivery shell, and the guide seat is located above the discharge port of the gas delivery shell. A flow pipe is fixedly connected to the side of the gas regulating shell close to the gas delivery shell, and the guide seat and the hexagonal groove at the bottom of the flow pipe are slidably connected.

[0011] The guide seat is placed close to the gas delivery shell and enters the hexagonal groove at the bottom of the circulation pipe, which facilitates the rapid positioning of the gas delivery shell and the gas regulating shell, thereby improving the assembly speed of the gas delivery shell and the gas regulating shell.

[0012] Preferably, the upper surface of the gas regulating shell is fixedly connected to a protective shell, and the inner wall of the gas regulating shell is symmetrically fixedly connected to a first adjusting plate and a second adjusting plate, a lifting block is provided between the first adjusting plate and the second adjusting plate, and the lifting block is located below the protective shell, the upper surface of the lifting block is fixedly connected to a linkage seat, the inner wall of the protective shell is rotatably connected to a second screw rod, and the threaded surface of the second screw rod is meshed with the inner wall of the circular groove of the linkage seat, and the top of the second screw rod is fixedly connected to a second rotating wheel.

[0013] Rotate the second rotating wheel to drive the second screw rod to rotate on the inner wall of the protective shell. The threaded surface of the second screw rod contacts the inner wall of the circular groove of the linkage seat, driving the lifting block to move upward. When the lifting block moves upward, the gap between the first adjustment plate and the second adjustment plate expands, making it easier to adjust the gas delivery flow rate.

[0014] Preferably, the surface of the gas regulating shell is symmetrically fixedly connected with a disassembly rod, the surface of the gas delivery shell is symmetrically fixedly connected with a disassembly seat, the bottoms of the two disassembly rods are fixedly connected with a snap block, and the snap block is slidably connected with the inner wall of the rectangular groove of the disassembly seat.

[0015] Place the gas regulating shell close to the gas delivery shell, the disassembly rod close to the disassembly seat, and the buckle block on the inner wall of the rectangular groove of the disassembly seat to limit the gas regulating shell.

[0016] Preferably, sliders are slidably connected to the inner walls of the rectangular grooves on both sides of the snap block, and the two sliders are fixedly connected to springs on one side close to the snap block, and the springs are fixedly connected to the inner walls of the rectangular grooves on both sides of the snap block on the other side away from the sliders.

[0017] When the snap block passes through the rectangular groove of the disassembly seat, the spring resets and opens, moving the slider out of the inner walls of the rectangular grooves on both sides of the snap block, firmly connecting the disassembly rod and the disassembly seat, and firmly connecting the gas delivery shell and the gas regulating shell. The splicing design makes it easy to disassemble and replace when there is a problem with the internal mechanism of the gas delivery shell or the gas regulating shell.

By installing the gas delivery shell, gas regulating shell, injection pipe, movable rod and first screw, the integrated flamethrower gas flow regulating assembly is changed to a spliced ​​design, which facilitates the replacement and maintenance of the gas delivery shell and gas regulating shell.

[0022] 2. Sliders are slidably connected to the inner walls of the rectangular grooves on both sides of the snap block. The two sliders are fixedly connected to the side of the snap block close to the snap block with springs, and the side of the spring away from the slider is fixedly connected to the inner walls of the rectangular grooves on both sides of the snap block. When the snap block passes through the rectangular groove of the disassembly seat, the spring resets and opens, and the slider is moved out of the inner walls of the rectangular grooves on both sides of the snap block, firmly connecting the disassembly rod and the disassembly seat, and firmly connecting the gas delivery shell and the gas regulating shell. The splicing design makes it easy to disassemble and replace when there is a problem with the internal mechanism of the gas delivery shell or the gas regulating shell.
