Abstract
Description
Technical Field
[0001] The utility model relates to the field of outdoor supplies, in particular to a semi-enclosed blowtorch. Background Art
[0002] The blowtorch is a newly emerging outdoor supply and belongs to a kind of outdoor cooking utensil. It is an ignition and heating tool derived from the existing butane gas cylinder. Outdoor cooking utensils generally refer to a stove head and fuel (butane gas cylinder) for cooking and boiling water in the wild, and are very convenient to carry. The blowtorch replaces the function of the stove head, liberates the flame from a fixed position, and is convenient for lighting a bonfire and roasting food on the spot. After the existing blowtorch is used, the nozzle still has residual heat, and it is easy to get burned if accidentally touched, resulting in blisters or even scars. At the same time, since there is only one flame ejection hole provided on the flame ejection head, the ejected flame is relatively concentrated and has a small divergence degree, increasing the fuel consumption.
[0003] Therefore, it is necessary to provide a new semi-enclosed blowtorch to solve the above technical problems. Content of the Utility Model
[0004] To solve the above technical problems, the utility model provides a semi-enclosed blowtorch.
[0005] The semi-enclosed blowtorch provided by the utility model includes: a blowtorch main body, a protective shell is fixedly connected to the left end of the blowtorch main body, a rotary button is rotatably connected to the rear side of the top of the protective shell, a bidirectional threaded rod is fixedly connected to the middle of the bottom of the rotary button, the bidirectional threaded rod is symmetrically threaded with moving plates up and down, the left sides of the two moving plates are respectively fixedly connected to the rear side of the lower closed box and the rear side of the upper closed box, a flame ejection pipe is fixedly connected to the middle of the left side of the blowtorch main body, a flame ejection head is fixedly connected to the left end of the flame ejection pipe, a first empty groove is arranged on the left side of the front side of the protective shell, and moving plates are slidably connected to the upper and lower parts inside the first empty groove. When the blowtorch is used up, by rotating the rotary button, the bidirectional threaded rod is driven to rotate, driving the two moving plates to slide along the inside of the first empty groove, so that the two moving plates approach each other, driving the rear side of the lower closed box and the upper closed box to approach each other, and finally closing the flame ejection head, preventing the flame ejection head from having residual heat and being easily touched and burned, resulting in blisters or even scars. At the same time, when in use, by rotating the rotary button in reverse, the flame ejection head is exposed. At this time, by pressing the blowtorch switch, the gas in the gas cylinder enters the inside of the blowtorch main body, and then is mixed with the air entering from the air inlet, and is transported to the flame ejection head and ignited. The flame is ejected through the main flame ejection port and the auxiliary flame ejection port, increasing the diffusion area of the open flame and having a better ignition effect.
[0006] Preferably, a fixing column is fixedly connected to the front left side inside the protective case. Support plates are symmetrically and slidably connected above and below the fixing column. The left sides of the two support plates are respectively fixedly connected to the front sides of the lower closed box and the upper closed box. A second empty slot is provided on the right side of the front side of the protective case. Support plates are slidably connected above and below inside the second empty slot. Through the support plates and the fixing column, the lower closed box and the upper closed box are supported and limited, enabling them to move stably.
[0007] Preferably, a main spray nozzle is provided in the middle of the front side inside the flame spray head. Auxiliary spray nozzles are provided on the four sides of the front side of the flame spray head. The flame is ejected through the main spray nozzle and the auxiliary spray nozzles, increasing the diffusion area of the open flame and achieving a better ignition effect.
[0008] Preferably, a handle is fixedly connected to the middle of the lower part of the flame spray gun body. A flame spray gun switch is provided in the middle of the left side of the handle. An air tank is provided at the lower end of the handle. By pressing the flame spray gun switch, the gas inside the air tank enters the inside of the flame spray gun body.
[0009] Preferably, an air inlet is provided at the right end of the flame spray gun body. The gas inside the air tank is mixed with the air entering through the air inlet to increase the combustion efficiency.
[0010] Compared with the related technology, the semi - enclosed flame spray gun provided by the present utility model has the following beneficial effects:
[0011] 1. The present utility model provides a semi - enclosed flame spray gun. By installing the upper and lower closed boxes, it prevents the flame spray head from having residual heat, which may easily cause burns, resulting in blisters or even scars.
