Abstract
A microwave heating cavity includes a metal shell, a heating sleeve, a dielectric medium, an antenna bracket, a ceramic rod and a metal wire. The metal shell is provided with a middle cavity extending through the metal shell and including a first mounting cavity, a concave air cavity and a second mounting cavity. The heating sleeve is mounted in the first mounting cavity. An accommodating cavity is arranged in the heating sleeve, in which the dielectric medium is arranged. The antenna bracket is mounted in the second mounting cavity. The ceramic rod is mounted on the antenna bracket. The ceramic rod extends into the accommodating cavity and is in contact with the dielectric medium. The metal wire is spirally wound around the ceramic rod and is configured to be connected with an external power.
