Description

Technical Field

[0001] The utility model belongs to the technical field of gas appliances, and in particular relates to a flamethrower with a protective shell. Background Art

[0002] In recent years, with the rise of outdoor camping, company team building and other activities, a large number of people have been attracted to participate in outdoor activities. The flamethrower is a new outdoor product and a kind of outdoor cooking utensils. It is an ignition and heating tool derived from the existing butane gas cylinder. The existing flamethrowers can be divided into large flamethrowers and small flamethrowers according to their volume. The small flamethrower is usually composed of two main parts, a main body that controls the flame and a gas cylinder that stores gas and supplies gas to the main body. The gas cylinder and the main body are usually inseparable, and the gas is directly replenished by inflation for continuous use. However, the gas cylinder of the small flamethrower is usually directly exposed to the outside world. When the gas cylinder is hit by the outside world or the outside temperature is too high, it will explode, posing a safety hazard. Summary of the invention

[0003] The specific technical solution of the utility model is: a flamethrower with a protective shell, in particular a small flamethrower, comprising a main body for controlling flamethrowing, a protective shell for protecting a gas cylinder installed on the main body, a gas cylinder for providing the gas required for flamethrowing accommodated in the protective shell, the gas cylinder is connected to the main body and communicated, and the gas cylinder is protected by this arrangement, thereby preventing the gas cylinder from being directly exposed and being hit or affected by high temperature and causing explosion.

[0004] According to the above technical solution, further, an assembly groove is provided in the main body, and a hanging ear which can be inserted into the assembly groove is provided on the gas cylinder. When the hanging ear is inserted into the assembly groove, the main body and the gas cylinder are connected and assembled.

[0005] According to the above technical solution, a card slot is further provided on the main body, and a card block for inserting into the card slot is provided on the inner wall of the protective shell, thereby completing the connection between the main body and the protective shell.

[0006] According to the above technical solution, a positioning groove is further provided on the main body at a position corresponding to the card slot, and a positioning strip is provided on the inner wall of the protective shell, so that the protective shell is inserted upward into the positioning groove through the positioning strip and docked with the main body.

[0007] According to the above technical solution, the main body further includes a left shell body and a right shell body, and the left shell body and the right shell body are fixed by screws. The bottom walls of the left shell body and the right shell body are provided with assembly grooves. The hanging ears on the gas cylinder can be directly pushed into the assembly grooves on the left shell body or the right shell body, and then the left shell body and the right shell body are connected to complete the connection between the main body and the gas cylinder.

[0008] According to the above technical solution, further, the side wall of the left shell is provided with a left reinforcing rib, the side wall of the right shell and the position corresponding to the left reinforcing rib are provided with a right reinforcing rib, the bottom wall of the left shell is provided with two first positioning ribs, and the bottom wall of the right shell is provided with a second positioning rib at a position corresponding to the first positioning rib. When the left shell and the right shell are docked, the left reinforcing rib can be inserted into the right reinforcing rib to strengthen the stability of the middle part of the main body, and the second positioning rib can be inserted between the two first positioning ribs to strengthen the stability of the bottom of the main body, and then the fixation between the left shell and the right shell can be completed by tightening the screws.

[0009] According to the above technical solution, the bottom of the protective shell is further extended inwardly to be provided with an inner step. After the protective shell is connected to the main body, the inner step of the protective shell conflicts with the bottom of the gas cylinder, so that the protective shell pushes the gas cylinder tightly to prevent the gas cylinder and the main body from loosening. Through this arrangement, the gas can be delivered more stably when the flamethrower is in use.

[0010] According to the above technical solution, the diameter of the gas cylinder is smaller than the main body, and the diameter of the protective shell is larger than the gas cylinder and equal to the diameter of the main body. This arrangement makes the overall appearance of the flamethrower more coordinated and beautiful.

[0011] According to the above technical solution, a pressing part is further provided on the main body, and a gas starting part is provided below the pressing part. An air pipe is installed on the outlet valve of the gas bottle, and a seesaw for controlling the gas outlet is installed below the outlet valve. The gas starting part is in conflict with the seesaw. When the pressing part pushes the gas starting part downward, the seesaw opens the outlet valve of the gas bottle by prying, so that the gas bottle provides the gas required for flame spraying to the main body through the air pipe.

[0012] According to the above technical solution, a nozzle is further provided on the port of the air pipe, and the nozzle is fixed on the main body, so that the air pipe can stably supply air and the nozzle can also stably spray fire. A piezoelectric igniter is provided inside the main body below the pressing part, and a conductive wire is connected to the bottom end of the piezoelectric igniter, which is connected to the nozzle. When the pressing part is pressed down, it will press and start the piezoelectric igniter to conduct electricity to the air outlet end of the air pipe through the conductive wire for ignition.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: by arranging a protective shell on the main body to protect the gas cylinder, the problem of the gas cylinder being directly exposed to the outside is solved, the gas cylinder can be protected, and the risk of the gas cylinder exploding due to impact or high temperature is reduced. Even if there is an explosion, the protective shell can isolate the explosion and protect the user from being affected by the explosion. At the same time, a card block and a positioning strip are arranged on the inner wall of the protective shell, and the card block and the positioning strip are adapted to the card slot and the positioning slot on the main body, so that the protective shell can be quickly assembled with the main body, and a hanging ear is arranged on the gas cylinder, through which the gas cylinder can be directly assembled with the main body, and the inner step arranged at the bottom of the protective shell can press against the gas cylinder to prevent the gas cylinder from loosening. The structures cooperate with each other, which reduces the overall assembly time of the flamethrower, improves the overall assembly efficiency, and achieves the purpose of reducing costs and increasing efficiency.
