High borosilicate glass container with embedded IH electromagnetic heating structure Technical Field The invention relates to the technical field of heating of high borosilicate glass containers, in particular to a high borosilicate glass container with an embedded IH electromagnetic heating structure. Background Currently, IH electromagnetic heating is gradually applied to the field of daily containers such as glass kettles, glass health preserving kettles, glass stewpots and the like by virtue of the advantages of high efficiency, energy conservation and environmental protection, and high borosilicate glass becomes a main stream material of the containers due to the characteristics of high temperature resistance and good thermal stability. However, the conventional electromagnetic heating structure of the high borosilicate glass container IH has a plurality of technical defects which are difficult to overcome, and the technical defects are as follows: (1) Generally, a mica sheet, a ceramic sheet, a silica gel pad and other rigid or semi-rigid heat insulation gaskets are adopted to separate the induction heating body from the bottom of the glass container. However, the gasket cannot be completely attached to the glass and the heating element, an air gap is easily formed, so that the thermal resistance is increased, the heat conduction is uneven, local high temperature aggregation is easy to cause the problem that the high borosilicate glass is frequently fried to bottom and cracked due to thermal stress, and the potential safety hazard is extremely large. (2) The heating element is in rigid contact with the bottom of the glass through the gasket, and the heating element directly extrudes the inner wall of the glass after being heated and expanded.
