Description

Technical Field

[0001] This utility model relates to a portable gas stove structure that reduces the thermal conductivity of the combustion chamber and gas tank, belonging to the field of portable gas stove technology. Background Technology

[0002] Most existing portable gas stove products, such as Figure 1 As shown, the combustion chamber is located in a square shell, and the side of the square shell is connected to the gas tank compartment. When the burner is working, some of the heat generated cannot be quickly dissipated outward, and is instead transferred along the square shell to the gas tank compartment. The gas tank in the gas tank compartment receives too much heat, which can cause the gas tank temperature to become too high, easily leading to the safety hazard of gas tank explosion. Explosions caused by excessive gas tank temperature are an important cause of safety accidents involving portable gas stoves. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a portable gas stove structure that reduces the thermal conductivity of the combustion chamber and the gas canister, thereby reducing the efficiency of heat transfer to the gas canister, decreasing the amount of heat received by the gas canister, and improving the safety of portable gas stove use.

[0004] The technical solution of this utility model is: a cassette furnace structure that reduces the thermal conductivity of the combustion chamber and the gas tank, wherein the combustion chamber and the gas tank are connected by a connecting pipe, and the diameter of the connecting pipe is smaller than that of the gas tank.

[0005] The connecting pipe is either a circular pipe or a square pipe.

[0006] The connecting pipe has heat dissipation holes in its wall.

[0007] The connecting pipe is fixedly connected to the middle of the gas tank compartment.

[0008] The gas supply pipeline between the gas tank and the burner is extended via a connecting pipe.

[0009] The burner is located in the middle of the combustion chamber.

[0010] The outer wall of the combustion chamber is provided with support leg a, and the bottom of the gas tank chamber is provided with support leg b.

[0011] The top height of the combustion chamber is lower than the top height of the gas tank chamber.

[0012] The beneficial effects of this utility model are: reducing the enclosed space between the combustion chamber and the gas tank chamber, thereby reducing heat transfer from the combustion chamber to the gas tank chamber, reducing the heat received by the gas tank inside the gas tank chamber, and making it safer to use; opening heat dissipation holes in the connecting pipe wall accelerates the heat transfer from the inside of the pipe to the outside, further reducing the heat conduction to the gas tank chamber.

[0014] Figure 2 This is a perspective view of the present utility model;

[0015] Figure 3 This is the front view of the present invention.

[0016] The attached diagram is labeled as follows: 1. Combustion chamber, 2. Gas tank chamber, 3. Connecting pipe, 4. Burner, 5. Support leg a, 6. Support leg b. Detailed Implementation

[0017] The following is in conjunction with the appendix Figure 2-3 Further explanation of this utility model:

[0018] A portable gas stove structure for reducing the thermal conductivity of the combustion chamber and gas tank is disclosed. The combustion chamber 1 and the gas tank 2 are connected by a connecting pipe 3. The opening of the connecting pipe 3 is square, and its diameter is smaller than that of the gas tank 2, thus reducing the connection area between the connecting pipe 3 and the gas tank 2. This reduces the enclosed heat conduction area and decreases the heat conduction to the gas tank 2. The connecting pipe 3 has ventilation holes in its wall to facilitate heat dissipation, further reducing heat conduction to the gas tank 2. Additionally, during operation, a large amount of heat accumulates at the top of the combustion chamber 1. By designing the top of the combustion chamber 1 to be lower than that of the gas tank 2, the straight-line distance between the two chambers is increased, thereby expanding the heat conduction space between them. This helps heat diffuse to other areas and reduces the amount of heat received by the gas tank 2 from the top of the combustion chamber 1.

[0019] The connecting pipe 3 is fixedly connected to the middle of the gas tank 2, making the overall structure more balanced and stable.

[0020] The connecting pipe 3 connects the combustion chamber 1 to the gas tank 2. The valve body at the end of the gas tank 2 is connected to the gas supply pipeline. The gas supply pipeline passes through the connecting pipe, which protects the gas supply pipeline. After passing through the connecting pipe 3, the gas supply pipeline is connected to the burner 3. The burner 4 is located in the middle of the combustion chamber 1.

[0021] The outer wall of the combustion chamber 1 is provided with support leg a5, and the bottom of the gas tank chamber 2 is provided with support leg b6. Support leg a5 and support leg b6 work together to support the whole. When the support surface is horizontal, support leg a5 and support leg b6 can make the upper surface of the combustion chamber 1 horizontal, thereby making the pot placed on top of the combustion chamber 1 more stable.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
