The parts from the bottom shell to the top cover are locked onto the third gasket with bolts and nuts, and the outer edge of the bottom shell is rolled inward and compacted using a spinning method. The AC heating plate consists of a plate frame and a circular heating wire wound around the plate frame. One end of the circular heating wire is the left terminal, and the other end is the right terminal. The plate frame is stamped from a non-conductive, high-temperature resistant mica plate, with several small grooves on its inner and outer edges for winding the circular heating wire. The right terminal at its opening is electrically connected to and pressed into the common terminal, and the left terminal is electrically connected to and pressed into the AC terminal. The structure of this AC heating plate is complex, and the circular heating wire is not wound evenly, so further improvements are needed. Utility Model Content
