Description

Technical Field

[0001] The utility model relates to the technical field of demagnetizers, in particular to a planar demagnetizer. Background Art

[0002] Demagnetizer generally refers to a demagnetizer, which uses an electromagnet with an open core and is passed through a 50 Hz alternating current. When demagnetizing, the object to be demagnetized is first brought close to the demagnetizer to saturate the magnetism, and then gradually moved away, so that the hysteresis loop gradually shrinks until the residual magnetism is eliminated. A damped oscillating current can also be passed through the coil of the electromagnet to make a demagnetizer. When demagnetizing a mechanical watch, a planar demagnetizer is provided.

[0003] Demagnetizers are usually composed of the following main components: power system, coil system, control system and housing. The power system provides energy for the entire device to ensure its normal operation and demagnetization effect. The coil system is the core part of the demagnetizer. It generates a changing magnetic field through the change of current, which in turn affects the magnetism of the magnetic material. The control system is responsible for monitoring and controlling the intensity of the current and magnetic field to achieve precise demagnetization effect. The housing plays a role in protecting the equipment components and user safety.

[0004] However, the existing demagnetizer has a poor protective effect on the connection position of the shell. If rust occurs, it can only be repaired by destroying the shell. Utility Model Content

A second cavity 21 is opened inside the second shell 11. The setting of the second cavity 21 facilitates the installation of the coil system 9 inside the second shell 11. The coil system 9 is arranged inside the second cavity 21. The front side of the circuit board 3 is electrically connected to the outer side of the coil system 9 through two first wires 5. The coil system 9 can form a magnetic field to demagnetize the watch. The outer side of the coil system 9 is electrically connected to the front side of the circuit board 3 through the second wire 4.

[0024] In the specific implementation process, it is worth pointing out that the threaded hole 7 and the screw 15 are arranged inside the opening 19, so that they can be covered by the cover plate 16 to avoid rust when they come into contact with water. After the first shell 1 and the second shell 11 are assembled, the first cavity 20 and the second cavity 21 form a complete cavity structure, which is convenient for installing and fixing the electronic components inside;

[0025] Furthermore, a notch 18 is provided at the top of the opening 19 , and a logo 14 is processed on the front of the first housing 1 .

[0026] In the specific implementation process, it is worth pointing out that the notch 18 can facilitate the user to lift the cover 16, and the mark 14 can facilitate the user to find the demagnetization position of the mechanical watch;

[0027] Furthermore, a switch 12 is movably connected to the circular hole on the front side of the first housing 1 , and an indicator light 13 is installed inside the switch 12 .

[0028] In the specific implementation process, it is worth pointing out that the switch 12 can control the switch of the demagnetizer, and the indicator light 13 can display the current working status;

[0033] Specifically, when the planar demagnetizer is used, the connection position of the screw 15 is closed through the cooperation between the coil system 9, the first bolt 10 and the cover plate 16, so as to avoid water immersion in the screw 15 position, thereby solving the problem that the existing demagnetizer has poor protection effect on the shell connection position. If rust occurs, it can only be repaired by destroying the outer side. When disassembly is required, the cover plate 16 can be easily opened by fingers through the notch 18, which makes it convenient to use the working disassembly screws 15, so that the first shell 1 and the second shell 11 can be separated, which is convenient for repairing the interior. Of course, when the watch needs to be demagnetized, the watch can be placed at the mark 14 position, and the overall external power supply can be turned on and the steps can be followed.
