Technical Field

[0001] The utility model relates to the technical field related to the demagnetization of mechanical watches, in particular to a demagnetizer for mechanical watches. Background Technique

[0002] Because watch repair itself is a niche industry, and watch repair tools are also a niche industry. The production volume of watch repair tools is small and the profit is low. In the past, most of the watch repair tools in China were imported from abroad, a small part were produced by some domestic manufacturers, and some were tools made by watch repair masters themselves. However, the tools produced by domestic manufacturers generally have poor quality and are very difficult to use. Currently, the commonly used detection tool in the domestic market is a mechanical compass, and the commonly used demagnetizer is an industrial inductive coil. Therefore, in order to improve the accuracy of the demagnetizer, there is a particular need for a demagnetizer for mechanical watches.

[0003] Because for existing demagnetizers, most demagnetizers use industrial inductive coils, not only the demagnetization is not thorough, but also if used improperly, it will damage the watch, with extremely low efficiency and insufficient precision, resulting in the problem of not being able to meet the current requirements. Content of the Utility Model

[0004] The purpose of the utility model is to provide a demagnetizer for mechanical watches to solve the problems in the above background technique, that is, for existing demagnetizers, most demagnetizers use industrial inductive coils, not only the demagnetization is not thorough, but also if used improperly, it will damage the watch, with extremely low efficiency and insufficient precision, resulting in the problem of not being able to meet the current requirements.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A demagnetizer for mechanical watches, including a housing, on the inner surface of the housing is provided a first inductor, on the outer surface of the first inductor is fixedly connected a wire, on the inner surface of the housing is provided a five-volt power supply, on one side surface of the housing is fixedly connected a first main board, on one side surface of the housing is fixedly connected a screen display, on the inner surface of the housing is fixedly connected a second main board, on the outer surface of the housing is fixedly connected a product film, and on the inner surface of the housing is fixedly connected a capacitor.

[0006] Preferably, the second main board is fixedly connected to the first main board through a wire, and on the other side surface of the housing is fixedly connected a screen display.

[0007] Preferably, the first main board is fixedly connected to the inner surface of the housing, and the capacitor is fixedly connected to the first main board through a wire.

[0008] Preferably, the 5V power supply is closely attached to the bottom surface of the housing, and the first inductor is symmetrically arranged with respect to the central axis of the housing.

[0009] Preferably, the first inductor is closely attached to the bottom surface of the housing, and a product film is fixed on the other surface of the housing.

[0010] Preferably, the capacitor is closely attached to the bottom surface of the housing.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: When using this degausser for mechanical watch demagnetization, when it is necessary to use the degausser, first, plug in the device power supply, and then touch the power button. The device will automatically turn on, and at the same time, the program will self-check and clear. Place the watch in the detection area. The second main board in the detection area will detect whether the watch is magnetized. At the same time, you can observe the screen display to see if there is a magnetic field intensity indication. If there is magnetism, different small black dots will be displayed on the screen display. The size of the black dots varies according to the magnetic field intensity of the magnetized watch. The larger the black dot, the stronger the magnetic induction. At this time, place the watch in the demagnetization area and touch the demagnetization button for one second. Then you will hear a ticking sound, and the device will automatically demagnetize five times. Each time it makes a sound, turn the watch 90 degrees in the same direction, turn it once for each sound, a total of five sounds and four turns. The demagnetization is completed. When the magnetic force line direction of the demagnetizing magnetic field is the same as that of the magnetized watch, the demagnetization effect is the best, and when they are at 90 degrees to each other, it is ineffective. Therefore, multi-directional demagnetization of the watch is required. If you want to continue demagnetization, operate in the same way. If it is a tool with a larger volume, multiple demagnetizations are required for better results. The device can demagnetize multiple times without affecting the watch or magnetizing the watch. The first inductor installed inside the demagnetizer can perform electromagnetic induction on the mechanical watch. The wire can connect the first inductor and the 5V power supply. When the 5V power supply is connected, it can supply power to the first main board and provide a demagnetizing current for the main board. At the same time, the first main board is fixedly connected to the screen display through the housing of the demagnetizer, so that it can be observed through the screen display whether there is residual magnetism in the watch. Finally, the capacitor inside the demagnetizer can store electricity and then provide a demagnetizing current for the demagnetizer. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4, the present utility model provides a technical solution: a degausser for demagnetizing mechanical watches, including a housing 1, a first inductor 2 is arranged on the inner surface of the housing 1, a wire 3 is fixedly connected to the outer surface of the first inductor 2, a five-volt power supply 4 is arranged on the inner surface of the housing 1, a first main board 5 is fixedly connected to one side surface of the housing 1, a screen display 6 is fixedly connected to one side surface of the housing 1, a second main board 7 is fixedly connected to the inner surface of the housing 1, and a product film 9 is fixed on the outer surface of the housing 1. 8, a capacitor 6 is fixedly connected to the inner surface of the housing 1. Through the settings of the housing 1, the first inductor 2, the wire 3, the five-volt power supply 4, the first main board 5, the screen display 6, the second main board 7, the product film 8, and the capacitor 6, when in use, when the degausser needs to be used, first, plug in the device power supply, and then touch the power button, the device will automatically turn on, and at the same time, the program will self-check and clear. Place the watch in the detection area, and the second main board on the detection area will detect whether the watch is magnetized. At the same time, you can observe the screen display 8 to see if there is a magnetic field intensity indication. If there is magnetism, different small black dots will be displayed on the screen display 8. The size of the black dots varies according to the magnetic field intensity of the magnetized watch. The larger the black dot, the stronger the magnetic induction. At this time, place the watch in the demagnetization area and touch the demagnetization button for one second. Then you will hear a ticking sound, and the device will automatically demagnetize five times. Each time it rings, turn the watch 90 degrees in the same direction. It rings once and turns once, for a total of five rings and four turns. The demagnetization is over. When the magnetic force line direction of the demagnetizing magnetic field is the same as that of the magnetized watch, the demagnetization effect is the best. When they are at a 90-degree angle, it is ineffective. Therefore, the watch needs to be demagnetized in multiple directions. If you want to continue demagnetizing, operate in the same way. If it is a larger tool, multiple demagnetizations will have a better effect. The device can demagnetize multiple times without affecting the watch or magnetizing the watch. The first inductor 2 installed inside the degausser can perform electromagnetic induction on the mechanical watch. The wire 3 can connect the first inductor 2 and the five-volt power supply 4. When the five-volt power supply 4 is connected, it can supply power to the first main board 5 and extend the service life of the first main board 5. At the same time, the first main board 5 is fixedly connected to the screen display 8 through the housing 1 of the degausser, so that it can be observed through the screen display 8 whether there is residual magnetism in the watch. Finally, the capacitor 6 inside the degausser can store electricity, and then provide demagnetizing current for the degausser.

[0019] Further, the second main board is tightly fixed under the product film 9 of the housing 1 through sealant. The bolts on the first main board 5 are closely attached to the housing 1. Through the detection of the second main board, it can be detected whether the watch is magnetized, and at the same time, it can be observed through the screen display 8 whether there is a magnetic field intensity indication.

[0020] Further, the second main board 7 is fixedly connected to the first main board 5 through a wire 3. A screen display 8 is fixedly connected to the other surface of the housing 1. Through the arrangement of the first main board 5, the housing 1 of the demagnetizer and the screen display 8 can be fixedly connected, so as to observe whether there is residual magnetism in the watch.

[0021] Further, the first main board 5 is fixedly connected to the inner surface of the housing 1. The capacitor 6 is fixedly connected to the first main board 5 through a wire 3. Through the arrangement of the capacitor 6, the electric quantity can be stored, and then a demagnetizing current can be provided for the demagnetizer.

[0022] Further, the five-volt power supply 4 is closely attached to the bottom surface of the housing 1. The first inductor 2 is symmetrically arranged with respect to the central axis of the housing 1. Through the arrangement of the five-volt power supply 4, the first main board 5 can be powered, and the service life of the first main board 5 can be extended.

[0023] Further, the first inductor 2 is closely attached to the bottom surface of the housing 1. A product film 9 is fixedly connected to the other surface of the housing 1. Through the arrangement of the first inductor 2, electromagnetic induction can be performed on the mechanical watch, and at the same time, the detection area and the demagnetization area can be indicated to the customer.

[0024] Further, the capacitor 6 is closely attached to the bottom surface of the housing 1. Through the arrangement of the housing 1, the circuits inside the demagnetizer can be protected, preventing dust from entering the demagnetizer and affecting the demagnetizer.

[0025] Working principle: When in use, when it is necessary to use the demagnetizer, first, plug in the device power supply, and then touch the power button. The device will automatically power on, and at the same time, perform a self-check and clear the data. Place the watch in the detection area. The second main board 7 on the detection area will detect whether the watch is magnetized. At the same time, you can observe the screen display 6 to see if there is a magnetic field strength indication. If there is magnetism, different small black dots will be displayed on the screen display 6. The size of the black dots varies according to the magnetic field strength of the magnetized watch. The larger the black dot, the stronger the magnetic induction. At this time, place the watch in the demagnetization area and touch the demagnetization button for one second. Then you will hear a ticking sound, and the device will automatically demagnetize five times. Each time it makes a sound, turn the watch 90 degrees in the same direction. It makes a sound and turns once, for a total of five sounds and four turns. The demagnetization is completed. When the magnetic field lines of the demagnetizing magnetic field and the magnetic field lines of the watch to be demagnetized are in the same direction, the demagnetization effect is the best. When they are at 90 degrees to each other, it is ineffective. Therefore, multi-directional demagnetization of the watch is required. If you want to continue demagnetization, operate in the same way. If it is a tool with a larger volume, multiple demagnetizations will have a better effect. The device can perform multiple demagnetizations without affecting the watch or magnetizing the watch. The first inductor 2 installed inside the demagnetizer can perform electromagnetic induction on the mechanical watch. The wire 3 can connect the first inductor 2 and the 5V power supply 4. When the 5V power supply 4 is connected, it can supply power to the first main board 5 and extend the service life of the first main board 5. At the same time, the first main board 5 is fixedly connected to the screen display 8 through the outer shell 1 of the demagnetizer, so that it can be observed through the screen display 8 whether there is residual magnetism in the watch. Finally, the capacitor 6 inside the demagnetizer can store electricity and thus provide a demagnetizing current for the demagnetizer.
