Description

Technical Field

[0001] The utility model relates to the technical field of gas cookers, and particularly relates to a burner with a special-shaped connection structure. Background Art

[0002] As the core component of a gas stove, the structural design and assembly quality of the burner are directly related to the user's safety and experience during use. Currently, in the connection and assembly between the burner cap seat and the burner head of traditional gas stoves, a structural design with a circular interface is generally adopted, but there is still a hidden danger of incorrect placement. This design cannot ensure the tight fit between the burner cap seat and the burner head after multiple installations and connections. Specifically, during actual use, due to reasons such as cleaning, when the burner cap seat needs to be disassembled and reassembled, it is often difficult to ensure its precise alignment with the burner head. That is, although the burner cap seat may visually seem to be placed in place, its actual position may not exactly coincide with the concentric circle structure of the burner head or the burner cap seat. This non-coincident state will result in a connection gap between the burner cap seat and the burner head, causing gas to leak out from these gaps during the combustion process. When these leaked gases encounter an open flame or high temperature, they are likely to trigger a fire or explosion accident, posing a serious threat to the user's life and property. Therefore, there is an urgent need for a burner with an anti-misassembly function when connecting the burner head and the burner cap seat. Summary of the Utility Model
