Description

Technical Field

[0001] This utility model relates to the field of cooking appliance technology, and in particular to a portable gas stove that is compatible with multiple gas sources. Background Technology

[0002] Portable gas stoves, as a type of portable gas cooking device, are widely used in outdoor camping, home emergencies, and other scenarios due to their lightweight and portability. Traditional portable gas stoves typically employ an integrated design, relying on a built-in disposable small gas canister (such as a butane canister) for gas supply. While this design offers portability, it still has the following significant drawbacks:

[0003] Limited gas supply capacity: The built-in disposable small gas canister is small in size and has a short burning time, which is difficult to meet the needs of long-term or multi-scenario cooking (such as outdoor multi-person dining or continuous heating scenarios). Users need to replace the gas canister frequently, resulting in high operating costs and poor environmental performance.

[0004] Structural safety hazards: Explosions frequently occur with portable gas stoves. One reason is the quality of disposable small gas canisters. Some poorly made gas canisters are thin and easily deformed by compression or punctured by sharp objects, leading to gas leakage and subsequent explosion. Another reason is the overall design of the portable gas stove. The distance between the flame source and the gas canister is too close, causing the gas canister to overheat and thus explode.

[0005] To address the above issues, we have developed a new technical solution. Utility Model Content
