Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic heating, in particular to an electromagnetic induction heating device. Background Art

[0002] Electromagnetic heating, also known as electromagnetic induction heating (EH), is a technology that uses components of an electronic circuit board to generate an alternating magnetic field. When a ferrous container is placed on top of it, the container's surface cuts through the alternating magnetic field lines, generating alternating currents (eddy currents) in the metal bottom of the container. These eddy currents cause carriers at the bottom of the container to move at high speeds and irregularly. The collision and friction between these carriers and atoms generate heat, thereby heating the object. Because the heat is generated by the iron container itself, the heat conversion rate is extremely high, reaching up to 95%. This is a direct heating method. Induction cookers, induction stoves, and induction heating rice cookers all use electromagnetic heating technology. Electromagnetic heating coils: A high-frequency, high-voltage current flows through the coil, generating a rapidly varying alternating magnetic field. When a ferrous container is placed on top of it, the container's surface cuts through the alternating magnetic field lines, generating alternating currents (eddy currents) in the metal bottom of the container. These eddy currents cause carriers at the bottom of the container to move at high speeds and irregularly. The collision and friction between these carriers generate heat. This has the effect of heating the object. That is, it converts electrical energy into magnetic energy, which generates induced eddy currents on the surface of the heated steel body.

[0005] However, when melting and sampling metal parts through electromagnetic heating, the metal parts are usually located inside the electromagnetic coil, and the electromagnetic coil then generates a high temperature on the metal parts, causing them to melt, thereby achieving sampling of the metal parts. However, during the heating process, if the metal parts melt, there is a possibility that they will drip onto the electromagnetic coil, causing the electromagnetic coil to be contaminated, and in severe cases, the electromagnetic coil to be damaged. Therefore, an electromagnetic induction heating device is needed to solve the above problem. Utility Model Content

[0019] Preferably, the protective sleeve and the shell are both designed with ceramic materials, and the longitudinal section of the protective sleeve adopts a T-shaped structure design.
