Hot air blower

Abstract

Provided is a hot air blower capable of adjusting an air pressure to an appropriate pressure by simply operating a pressure regulation valve and appropriately adjusting a heating value of the hot air blower. The hot air blower includes a fuel tank for storing fuel, an air compression pump for sucking air and compressing the air, a pressure regulation valve installed at the air compression pump to reduce the pressure of the compressed air, a burner assembly for receiving the fuel from the fuel tank and the air from the air compression pump, and a combustion chamber for receiving the fuel from the burner assembly and combusting the fuel, wherein the pressure regulation valve includes a high pressure regulation valve and a low pressure regulation valve, and a valve opening/closing means is installed at the low pressure regulation valve. Therefore, the pressure of the compressed air can be selectively regulated by the high-pressure regulation valve and the low-pressure regulation valve, which have different opening pressures, so that a heating value of the hot air blower can be readily adjusted to increase efficiency of the hot air blower.
