The burner cap is simple and practical in structure, high in adaptability, capable of effectively improving combustion efficiency and high in economic and practical value.

Description

Technical Field

[0001] This invention relates to the field of burner technology, and in particular to a burner cap. Background Technology

[0002] The burner cap, also known as the flame spreader, plays a role in ensuring uniform flame distribution, preventing backfire, protecting the internal structure, improving thermal efficiency, and enhancing the appearance during combustion.

[0003] The Shabaf single-burner burner is renowned for its efficient combustion, even flame distribution, durability, and high safety. It is typically equipped with a specially designed burner cap to achieve single-burner flame (also known as single-ring flame). Currently, most stoves in my country use an inner and outer ring flame design, and their corresponding burner caps also have inner and outer rings. However, these cannot be applied to the Shabaf single-burner burner to achieve the same inner and outer ring flame configuration. Therefore, the application of the Shabaf single-burner burner in my country is difficult to promote. To address this, we have developed a new burner cap structure specifically adapted to the Shabaf single-burner burner, changing its single-ring flame configuration to an inner and outer ring flame.
