The name of the invention is a liquid-fuel cooker, which relates to a liquid-fuel cooker with alcohol group or alkyl group, such as alcohol or diesel oil and coal oil as fuel, and mainly solves the problems that gas fuel, such as gas, liquefied gas and pipeline natural gas used in families and catering industry at present, has combustible and explosive characteristics and can easily cause safety hidden dangers, such as fires, gas cylinder explosion and gas poisoning accidents or natural gas pipeline leakage and the like. The liquid-fuel cooker has the characteristics that: N baffle plates arefixed in the cooker from top to bottom, an ignition slot is arranged on each baffle plate, and a nozzle is arranged in the ignition slot on the baffle plate at the uppermost layer. Liquid fuel is used by the cooker disclosed by the invention, and the liquid fuel mainly includes diesel oil, coal oil or alcohol, therefore, a container for containing the liquid fuel is free of pressure; because the fuel is nontoxic and is difficult to volatilize, combust or explode, the liquid-fuel cooker is safe to use; and the fuel is combusted stage by stage from top to bottom to ensure full combustion, the cooker has long service life, and the firepower is easy to control.
