Description

Technical Field

[0001] The utility model relates to the field of liquid fuel burners, in particular to a liquid fuel cartridge stove with a convenient oil tank replacement structure. 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] Existing liquid fuel combustion devices usually use a fuel storage tank, and as the fuel is consumed, an oil pump is used to supply fuel, which is usually used in fixed stoves such as home or commercial. Due to the presence of the oil pump, the stove itself is relatively bulky and difficult to carry out.

[0004] In addition, during the use of the oil burner, the inner wall of the burner and the inner wall of the ejector tube will be attached to the oil, which will generally 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 burner will change, resulting in incomplete combustion, black smoke, carbon deposits at the burner, and fire holes, resulting in deflagration. Therefore, further improvements are needed. Utility Model Content
