[0015] 1. Through the setting of heating film and insulating shell, the heating film adopts AC heating film, which can effectively improve the heating time and enhance the customer experience. At the same time, in order to improve safety, the heating film adopts silicone heating film, which can effectively play an insulating effect and improve safety. The heating film is adhered to the aluminum plate through its own adhesive. An isolation piece is provided between the aluminum plate and the hot bed support plate. The isolation piece is made of insulating material, which can effectively prevent the hot bed support plate and the aluminum plate from being conductive, greatly improving the safety of the hot bed.
