It can be appreciated that the first plate 11 is too small, the heating area of the electromagnetic heating coil is larger than that of the first plate 11, which may cause high-temperature damage to the second plate 12, and may also cause waste of heat of the electromagnetic heating coil, while the diameter of the first plate 11 is too large, which is not beneficial to reducing production cost. Therefore, in order to simultaneously ensure the heat-resistant requirement of the panel body 1 and control the production cost, the difference between the diameter of the first plate portion 11 and the outer diameter of the electromagnetic heating coil should be controlled within a certain range, in this embodiment, |a-b|is less than or equal to 100mm, when the diameter of the first plate portion 11 is larger than the outer diameter of the electromagnetic heating coil, the area of the first plate portion 11 is larger than the heating area, so that the heat-resistant requirement of the panel body 1 can be satisfied, and simultaneously, the heat of the electromagnetic heating coil is effectively utilized, and when the diameter of the first plate portion 11 is smaller than the outer diameter of the electromagnetic heating coil, the heat-resistant requirement of the panel body 1 can be satisfied and the product quality can be ensured, while the production cost can be saved.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the specification and drawings of the present utility model or direct/indirect application in other related technical fields are included in the scope of the present utility model.
