As shown in fig. 1, the electronic tag for microwave oven according to the embodiment of the present invention includes an upper insulating layer 1, a lower insulating layer 2, and a resonant circuit layer sandwiched between the upper and lower insulating layers. Wherein, the upper and lower heat-insulating layers are made of heat-insulating and heat-resistant materials such as paper pulp, asbestos, glass fiber and the like; the electronic tag for the microwave oven is square, and can also be round or star-shaped and other structures.
Specifically, the resonant circuit layer includes first metal level 3 and the second metal level 4 of upper and lower distribution, goes up insulating layer 1 and passes through the laminating of first glue film 5 with first metal level 3, and the laminating of second glue film 6 is passed through with second metal level 4 to first metal level 3, and the laminating of third glue film 7 is passed through with insulating layer 2 down to second metal level 4. The areas of the upper heat-insulating layer 1 and the lower heat-insulating layer 2 are equal, the area of the heat-insulating layer is larger than that of the first metal layer 3, and the area of the heat-insulating layer is larger than that of the second metal layer 4, so that the metal layers distributed up and down are prevented from contacting under the action of electromagnetic waves, and burning or spark accidents are prevented. As shown in fig. 2, the first metal layer 3 and the second metal layer 4 can be bonded to each other via the second adhesive layer 6 by fusion bonding using a hot melt adhesive, an acrylic adhesive, or a resin, and the other adhesive layers can be bonded in the same manner. The structure of the second glue layer 6 is matched with the first metal layer 3 and the second metal layer 4.
The first metal layer 3 and the second metal layer 4 are formed by winding metal foils, the number of winding turns of the first metal layer 3 and the second metal layer 4 is one, and therefore the obtained first metal layer 3 and the second metal layer 4 are both square broken ring structures. Wherein, the distance between the boundary of the second metal layer 4 and the boundary of the lower heat insulation layer 2 is more than 0.5 mm. The metal foil is aluminum foil or copper foil.
Additionally, the utility model discloses be equipped with waterproof layer 0 outside last insulating layer 1, go up through the laminating of fourth glue film 8 between insulating layer 1 and the waterproof layer 0 promptly, waterproof layer 0 equals with the area of last insulating layer 1, and as freezing dewfall/waterproof measure, the surface can also have the structure of the heat-resisting resin film such as PET and PP.
Preferably, the lower heat insulation layer 2 is attached to the peelable layer through an adhesive layer, so that the electronic tag for the microwave oven can be conveniently packaged and adhered.
The utility model discloses an electronic tags for microwave oven through the structural design of stromatolite, can not produce electric arc, can be applied to the heating of unfreezing of frozen food, satisfies daily demand.
The foregoing has been a detailed description of the preferred embodiments and principles of the present invention, and it will be apparent to those skilled in the art that variations may be made in the specific embodiments based on the concepts of the present invention, and such variations are considered as within the scope of the present invention.
