Description

Technical Field

[0001] The utility model relates to the technical field of gas cookers, and particularly relates to a burner and a gas cooker with an anti-blocking central gas supply structure. Background Technique

[0002] On the market, in order to meet the demand of high-fire cooking, a combustion structure with an additional independent central high fire is introduced. In the exact center of the burner, by using the middle channel in the center of the central burner cap, in combination with a vertical nozzle, a nozzle seat and a high-fire gas supply pipe, an additional central high-fire gas supply structure is realized. For example, a high-fire stir-fry gas cooker disclosed in Patent No. CN202221292928.8.

[0003] However, in this central high-fire structure, the vertical nozzle is usually threadedly connected to the nozzle seat and locked under the furnace base board of the burner, and extends upward from the burner. During the actual cooking process, oil stains, food particles, etc. may drip from the burner onto the vertical nozzle or the high-fire gas supply pipe, thus blocking the nozzle or the high-fire gas supply pipe; resulting in unstable high-fire combustion, and even causing the risk of gas accumulation under the cooker panel and the cooker panel bursting after deflagration; cleaning the nozzle or the high-fire gas supply pipe requires disassembling the cooker panel, which is difficult to disassemble and install, and the user's cleaning and maintenance cycle is long. Therefore, further improvement is needed. Summary of the Utility Model
