The present application relates to the technical field of object drying, in particular to an electric heat blowing drying device, which comprises a shell and an inner container, the inside of the inner container is provided with a flow guide plate, a fan blade and a heating pipe, further comprising an air adjusting assembly arranged in front of the fan blade and a separation piece arranged at the bottom of the inner container; the air adjusting assembly is rotationally arranged on the side wall of the flow guide plate, the air adjusting assembly has a first air outlet for drying objects and a second air outlet for increasing the gas flow rate, the first air outlet and the second air outlet are moved to the front of the fan blade by rotation; the present application adjusts the air pressure and the air flow rate by arranging two air outlets, before drying, the high flow rate gas generated by the second air outlet blows off the hard water on the surface of the objects, and the separated hard water is isolated by the liquid collecting cavity. During the drying process, the hard water on the surface of the objects is reduced, thereby reducing the generation of scale and reducing the area that needs to be wiped.
