It is noted that the conductive nickel plate 1 is composed of a nickel row 1.1 and a nickel disk 1.2, the nickel row 1.1 serving as a first terminal. The platinum leakage pipe 2 is formed by a platinum main heating pipe 2.2 and a platinum outer heating pipe 2.1, the platinum outer heating pipe 2.1 is sleeved outside the platinum main heating pipe 2.2 and is positioned in an AZS bottom brick area 6, a gap exists between the platinum outer heating pipe 2.1 and the AZS bottom brick area 6, part of glass liquid can enter the gap, the glass liquid entering the gap is rapidly cooled under the action of the stainless steel cooling water jacket 3, the glass liquid can be prevented from leaking outwards, and meanwhile, the heating efficiency of the platinum main heating pipe 2.2 is not affected.
