Abstract
A burner head with an annular fire hole is characterized by comprising a base disc, isolation columns, a flow way cover, an outer circular fire cover and the annular fire hole. An outer circular fire fuel gas inlet hole and the isolation columns are arranged on the base disc, the flow way cover is fixed to the base disc, and therefore an outer circular fire fuel gas pre-mixing gas channel is formed. The outer circular fire cover is arranged on the base disc and the flow way cover, through holes slightly larger than the heads of the isolation columns are formed in the outer circular fire cover, the number of the through holes is equal to that of the isolation columns, the through holes correspond to the isolation columns in a one-by-one mode, the isolation columns are sleeved with the through holes, and the annular fire hole is formed between gaps between the through holes and the isolation columns. The annular fire hole enables the contact area between the flame and the air to be increased, the burning working condition can be improved, the emission of harmful gas is effectively reduced, and the heat efficiency is improved. The annular fire hole enables the size of the burner head to be decreased, and the burner head is exquisite and compact in overall structure, good in part process, easy to manufacture and low in cost.
