an electromagnetic coil

Abstract

The invention particularly relates to an electromagnetic coil, which comprises a coil bracket, a coil and a magnetic strip, wherein the coil bracket between the coil and the magnetic strip is provided with separation blades for bearing the coil; each separation blade is provided with one or more paste openings which are smaller than the end surface of the inner side of the magnetic strip; the paste openings communicate the coil and the magnetic strip; when the coil and the magnetic strip are pasted, the paste openings are coated with mucilage glue to form adhesive layers; and the adhesive layers fix the coil and the magnetic strip on the coil bracket through the paste openings. The electromagnetic coil has the beneficial effects that the coil and the magnetic strip on the coil bracket are communicated by the paste openings; and the coil and the magnetic strip can be stably fixed on the coil bracket once by the adhesive layers, so that the problems of a preparation technology of pasting for multiple times and unstable pasting are solved; the production efficiency can be improved; the cost is reduced; and the adhesive force among the coil, the magnetic strip and the coil bracket is further improved.

Description

technical field [0001] The invention relates to the field of appliances that realize external heating through electromagnetic, in particular to an electromagnetic coil. Background technique [0002] Existing electromagnetic coils are mainly used to heat the basic components of cooking utensils, such as electromagnetic cookers, electromagnetic rice cookers, and electromagnetic kettles. [0003] At present, a conductor enameled wire of an electromagnetic coil is wound into a circular coil or a spiral coil, and the circular coil or the spiral coil is fixed on the surface of the coil support with an adhesive, and the magnetic strip is fixed on the bottom surface of the coil support with an adhesive again. Or use adhesive to fix the magnetic strip on the coil support groove, and then use adhesive to fix the circular coil or helical coil on the surface of the coil support.

Problems solved by technology

[0003] At present, a conductor enameled wire of an electromagnetic coil is wound into a circular coil or a spiral coil, and the circular coil or the spiral coil is fixed on the surface of the coil support with an adhesive, and the magnetic strip is fixed on the bottom surface of the coil support with an adhesive again. Or use adhesive to fix the magnetic strip on the coil support groove, and then use adhesive to fix the circular coil or helical coil on the surface of the coil support. There are deficiencies in the production process: the coil and the magnetic strip are bonded twice way, resulting in low production efficiency, large amount of adhesive materials, resulting in high cost, etc.
