The gas tank separated handheld blowtorch head: It needs to be connected to a cartridge gas cylinder, with a large weight and volume, but it is not suitable for long-term handheld. The gas tank integrated handheld blowtorch: It is convenient to carry, generally smaller in volume and lighter in weight than the separated type. Therefore, the gas tank integrated handheld blowtorch with a small volume and light weight is more suitable for use during outdoor cooking.

[0004] Most of the current gas tank integrated handheld blowtorches have a base. The base increases the support area, making the blowtorch stable when placed. Sometimes, in order to make the blowtorch more stable outdoors, in addition to increasing the area, the weight of the base is also increased. However, during the use of outdoor cooking, the user needs to keep holding it all the time, and the base increases the overall weight, making it impossible for the user to hold the blowtorch continuously for a long time. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the base in the above-mentioned existing background art increases the overall weight, making it impossible for the user to hold the blowtorch continuously for a long time.

[0034] Please refer to Figures 1-8 , a hand-held blowtorch, comprising a gas cylinder 1, a flame spraying component 2 and a base 3. The flame spraying component 2 is arranged on the upper side of the gas cylinder 1. The flame spraying component 2 includes an ignition member 21, a positioning member 22 and a flame spraying pipe 23. The flame spraying component 2 further includes a housing 24. The flame spraying pipe 23 extends into the housing 24 to form a frame. The ignition member 21 includes a pressing button 211, an igniter 212 and a ventilation plate 213. The pressing button 211 is rotatably connected to the frame. The positioning member 22 locks the pressing button 211 by moving up and down. Pressing the pressing button 211 will press the igniter 212. At the same time, the bottom end of the ventilation plate 213 turns upward, so that the gas in the gas cylinder 1 enters the flame spraying pipe 23. The igniter 212 under pressure generates a spark to ignite the gas for flame spraying. Then, by moving the positioning member 22, the pressing button 211 is kept in the pressed state, so that the gas continuously enters the flame spraying pipe 23.

[0035] A first adjusting ring 4 is rotatably connected to the lower side of the positioning member 22. The first adjusting ring 4 is used to adjust the size of the flame. A second adjusting ring 5 is rotatably arranged on the flame spraying pipe 23. A clamping groove is formed on the inner ring of the second adjusting ring 5. An elastic clamping bead 231 is arranged on the flame spraying pipe 23. The clamping bead 231 is connected to the flame spraying pipe 23 through a spring. When the second adjusting ring 5 is rotated, the clamping bead 231 is pressed and the spring deforms. When the clamping bead 231 corresponds to the corresponding clamping groove, it enters the clamping groove under the elastic action of the spring, so as to stably position the second adjusting ring 5. An air inlet 232 is formed on the flame spraying pipe 23, and a through groove 241 for air to enter the air inlet 232 is also formed on the housing 24. Rotating the second adjusting ring 5 is used to adjust the air intake amount of the air inlet 232 and thus adjust the softness and hardness of the flame. A heat shielding cylinder 6 is connected to the flame spraying pipe 23. The heat shielding cylinder 6 is used for heat protection. A heat dissipation channel 61 is arranged between the flame spraying end of the flame spraying pipe 23 and the heat shielding cylinder 6. The heat dissipation channel 61 facilitates the heat inside the heat shielding cylinder 6 to flow out.

[0036] The base 3 is arranged at the bottom of the gas cylinder 1. A limiting groove 31 adapted to the bottom of the gas cylinder 1 is formed on the bottom. A connecting member 32 connecting the gas cylinder 1 and the base 3 is arranged in the limiting groove 31. The gas cylinder 1 and the base 3 can be separated through the connecting member 32. Separating the base 3 can reduce the weight and facilitate holding the hand-held blowtorch for a long time.

[0037] Specifically, the connecting member 32 includes a magnet 321 fixed to the bottom of the limiting groove 31 and an iron sheet 322 fixed to the bottom of the gas cylinder 1. The magnets 321 are symmetrically arranged, and the iron sheets 322 correspond to the magnets 321 one by one. The iron sheets 322 are fixed to the gas cylinder 1 by screws. Due to the suction force of the magnets 321, the disassembly and connection are relatively convenient and fast. The magnetic lines of force of the magnets 321 can easily penetrate the thin iron sheets 322, resulting in a strong magnetic force and stable connection. A groove 11 is formed on the bottom surface of the gas cylinder 1, and the iron sheet 322 is fixed to the top wall of the groove 11. The groove 11 is adapted to the magnet 321. The base 3 extends forward from the center of the bottle body (with the fire-spraying direction as the front) to increase the support area. When the gas cylinder 1 is connected to the base 3, the extending part of the base 3 and the fire-spraying pipe 23 are on the same side of the gas cylinder 1. The groove 11 has a calibration function, so that the extending part of the base 3 is directly below the fire-spraying pipe 23.

[0038] An installation groove through which the magnet 321 passes is formed at the bottom of the limiting groove 31. The weight of the base 3 is increased by the magnet 321. The magnet 321 acts as a connection component and also acts as a counterweight to increase the stability during placement. A fixing plate 33 for fixing the magnet 321 is arranged below the limiting groove 31. A fixing groove 3211 through which the fixing plate 33 passes is formed on the magnet 321. Fixing holes are formed on the fixing plate 33, and sliding grooves for the movement of the fixing plate 33 are formed on the base 3 to prevent the fixing plate 33 from separating from the base 3. The fixing plate 33 is inserted into the fixing groove 3211, and then screws are passed through the fixing holes and connected to the base 3 to fix the magnet 321.

[0039] Furthermore, in order to prevent the base 3 from separating from the gas cylinder 1 during transportation, a locking member 7 is arranged on the base 3, and a locking hole 12 is formed on the gas cylinder 1. The locking member 7 is a bolt, and the bolt is threadedly connected to the base 3. By rotating the bolt and inserting it into the locking hole 12, the gas cylinder 1 is longitudinally fixed.

[0040] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively realized. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the above principles, any deformation or modification of the embodiments of the present invention is possible.
