Abstract

Provided is a heating device. The heating device includes a cylinder body, a door body, an electromagnetic generating module and a radiating antenna. A heating chamber having a pick-and-place opening is defined in the cylinder body, and the heating chamber is configured to place an object to be processed. The door body is disposed at the pick-and-place opening and configured to open and close the pick-and-place opening. The electromagnetic generating module is configured to generate an electromagnetic wave signal. The radiating antenna is disposed in the cylinder body and electrically connected with the electromagnetic generating module to generate electromagnetic waves of a corresponding frequency according to the electromagnetic wave signal. The radiating antenna is configured to arch in a direction close to the object to be processed so as to eliminate the influence of an edge effect on the distribution uniformity of the electromagnetic waves in the heating chamber, and increase the energy density and distribution range of the electromagnetic waves while solving the problem of the production cost and improving the distribution uniformity of the electromagnetic waves.
