The ventilation device 200, the rotary drive 400 and the far-infrared microcrystalline heater 500 are respectively connected to the control box 170, and their working status is regulated by the controller inside the control box 170.

Multiple pressure plates 520 are provided, and the multiple pressure plates 520 are spaced apart along the edge of the heating plate 530, pressing the heating plate 530 between the mounting frame 510 and the pressure plates 520.

Each of the two electrodes 532 has a 5mm diameter wiring hole. The electrodes 532 are printed using high-temperature conductive silver paste or high-temperature conductive copper paste, and then cured by high-temperature baking. The far-infrared heating layer 533 is printed using graphene high-temperature conductive ink, and then cured at high temperature. The insulating layer 534 is printed using high-temperature ceramic ink, and then cured at high temperature. The above printing processes include, but are not limited to, screen printing, spraying, and scraping coating methods.
