Description

Technical Field

[0001] The utility model relates to the technical field of metal heating, in particular to a portable liquid crystal display electromagnetic heating metal device. Background Technique

[0002] A new generation of high-frequency induction heating power supply designed based on single-chip microcomputer control is based on the principles of high-frequency electromagnetic induction and Joule-Lenz's law. It uses the eddy current generated by a high-frequency induction coil to heat the workpiece, with fast heating speed, high thermal efficiency, no flame generation, and no environmental pollution. It is widely used in industrial and civil fields such as rapid metal heating, and is quite different from traditional handheld portable induction heaters.

[0003] In the Chinese invention patent application number: CN202111504710.4, there is disclosed a heater. Although this electric heater adopts zero-voltage soft start mode, frequency automatic tracking and phase adjustment circuit design technology, the induction heater obtains the best heating effect, improves the energy conversion efficiency, and also improves the electrical performance reliability of the product, achieving a reduction in the volume of the device, avoiding the large weight for the staff during use, reducing energy consumption and work efficiency. However, in actual operation, the user has no intuitive text prompt, which is prone to misoperation and difficult to use. It is unable to provide more relevant parameters and information to the user, such as the manufacturer information, voltage, current, temperature and other information. Overall, it limits the extensibility of human-computer interaction. When the user focuses on the operation, there is often no time to look at the signal lights and has to turn his head and stop to look, which affects work efficiency. It adopts a miniaturized design but does not have a portable design. Although it is small, it still has to be placed on the platform for operation and cannot give full play to the advantages of miniaturization. The heat dissipation holes of the main engine air-cooling system adopt a split design, resulting in a decline in the overall firmness and cooling effect. The handle adopts the shape of a gun, which limits the movement of the wrist, wastes materials, increases costs, and is a bit bulky. There is no supporting coil design, and it cannot heat some irregular metal appearances and the metal surfaces that cannot be inserted into the coil, losing a large number of application functions.
