[0023] It also includes an external charger 9, and a contactor is fixedly connected to the top of the external charger 9, and the contactor is vertically arranged from top to bottom. The upper shell 7a of the heater is composed of two parts, including a lower sealing plate and an upper support plate. The lower sealing plate and the top of the lower shell 7b of the heater are mutually engaged, and the upper support plate is sleeved on the top of the lower sealing plate. A circular cavity is opened on the top of the upper support plate, and the heating film plate 1 is clamped inside the circular cavity of the upper support plate. The lower sealing plate, the upper support plate and the top of the heating film plate 1 are all provided with sockets at the same position, and the sockets are mutually plugged with the connector 6, and the connector 6 is electrically connected to the battery 3. A number of contacts are arranged on the outer wall of the contactor, and the lower shell 7b of the heater is adapted to the external charger 9.

[0024] Through the above technical solution, the heating film plate 1 is made of polyimide, which is the main heat source. When started, the heating film plate 1 effectively generates heat to heat the surface of the plate placed thereon. The plate heating process is precisely regulated and controlled by the printed circuit board 2 to ensure that the temperature is maintained at the optimal heating level without causing overheating or damage to the plate. The battery 3 powers the device and provides the necessary electrical energy. The battery 3 is monitored by a dedicated battery temperature sensor 5 to ensure safe operation and prevent overheating.
