This invention discloses a multifunctional European-style wood-burning stove with auxiliary ash removal and enhanced combustion effect, belonging to the technical field of household heating and cooking equipment. It includes a stove shell, a combustion chamber, an auxiliary ash removal mechanism, an auxiliary combustion mechanism, a linkage mechanism, and multifunctional components. The auxiliary ash removal mechanism is located below the combustion chamber and includes an ash receiving plate, an eccentric shaft, and an ash removal auxiliary wheel. The auxiliary combustion mechanism includes a hand-cranked fan, a combustion air inlet, and an air outlet. The linkage mechanism connects the hand crank handle to the eccentric shaft and the hand-cranked fan. Through mechanical linkage design, this invention allows simultaneous input of combustion air and grate vibration for ash removal by operating the hand crank handle, effectively solving the problems of incomplete combustion, difficult ash removal, and dust generation in traditional wood-burning stoves. It also integrates oven and dual-burner functions, improving the overall utilization rate of the equipment.
