Description

Technical Field

[0001] This utility model relates to the field of stove accessories, and in particular to a burner for a flip-type gas stove. Background Technology

[0002] The existing integrated flip-top burner assembly mainly consists of four parts: bracket, burner head, burner frame, and burner distributor. However, the existing integrated flip-top burner assembly has many shortcomings in use: First, the gas duct is too short and there is no standard injection port, resulting in low gas pressure and poor injection effect. Second, design flaws lead to low load, low firepower, excessive flue gas, and low energy efficiency. Third, the burner assembly is too close to the panel, causing excessive temperature rise and thus reducing the stability of the household gas stove. Fourth, the air intake design is unreasonable, leading to oxygen deficiency combustion after prolonged combustion, resulting in yellow flames and blackening of the bottom of the pot.

[0003] The Chinese patent (CN 219156906U) improves upon the above problem by further refining the structure by adding an independent pressure heating source to increase the firepower of the burner (burner head). To this end, a burner for a high-firepower flip-type gas stove is proposed. Utility Model Content
