Description

Technical Field

[0001] The utility model relates to the field of liquid fuel burners, in particular to a household liquid fuel burner stove. Background Art

[0002] In addition to conventional gas combustion devices, there are also liquid fuel combustion devices on the market, such as mineral oils such as white oil. This liquid combustion device achieves combustion by atomizing and igniting the atomized gas. During the combustion process, the atomized white oil is easily liquefied into liquid fuel again and remains in the burner. A matching combustion structure needs to be set to ensure smooth combustion of white oil.

[0003] During the use of oil burners, oil will adhere to the inner wall of the burner and the inner wall of the ejector tube. Generally, the oil will be drained to the auxiliary oil tank through the oil drain pipe. If the oil drain pipe is blocked, the oil will block the atomized gas path, and the concentration of the mixed gas at the burner mouth will change, resulting in incomplete combustion, black smoke, and carbon deposits at the burner mouth blocking the fire hole, causing deflagration. How to facilitate the application of household burner stoves, facilitate timely oil return and reuse, and make the gas supply of liquid burners smooth and reasonable requires further improvement.
