PURPOSE: A gas burner device with a multi-stage combustion air inlet is provided to improve combustion efficiency by swirling the flow of combustion air and mixed gas. CONSTITUTION: A gas burner device with a multi-stage combustion air inlet comprises a burner body(20) and a combustion pipe(30). The burner body has a first combustion air inlet(24) and an inclined plate(22). The diameter of the inclined plate is gradually expanded. The inclined plate is inserted into the combustion pipe. The combustion pipe has a second combustion air inlet(34). Combustion air passing through the second combustion air inlet flows into the combustion pipe, and is secondly mixed with first mixed gas.
