[0044] In the information age, data security is paramount. During IT equipment repair and disposal, there is a risk of information leakage, necessitating data destruction of storage media to prevent data leaks. Most storage media currently consist of magnetic components, such as magnetic hard drives, floppy disks, and magnetic tapes. There are three main destruction methods: physical shredding, high-temperature incineration, and demagnetization. Demagnetizing magnetic storage components using equipment is more energy-efficient and environmentally friendly, making it suitable for office use. Existing demagnetization equipment typically includes a human-machine interface unit and a demagnetization unit. Usually, the magnetic storage component is manually placed in the demagnetization area, and the human-machine interface unit controls a capacitor to discharge to a coil, generating a momentary strong magnetic field to destroy the data on the magnetic storage medium. However, this type of equipment has low automation, poor security, and requires multiple manual steps. Errors during operation can easily expose the human body to a strong magnetic environment, causing harm.
[0045] To address the aforementioned issues, this application provides a demagnetizing device suitable for everyday office environments. It features a higher degree of automation, reducing unnecessary operational steps and simplifying the demagnetizing process. It also avoids direct contact between the human body and the demagnetizing area, ensuring human safety. The device is equipped with multiple sensors to achieve comprehensive monitoring of the demagnetizing environment of the magnetic media equipment during data destruction, and can send monitoring information in real time, improving the safety, transparency, and efficiency of the entire demagnetizing process. The following detailed description of the demagnetizing device 100 of this application is provided through an embodiment.
[0046] like Figure 1 , Figure 2 This application provides a demagnetizing device 100, comprising:
[0047] The inlet module 120 has an inlet 122 for inserting magnetic media, and the inlet module 120 is configured to draw magnetic media into the demagnetizing device 100.
[0048] The demagnetizing module 130 has a demagnetizing area. The loading module 120 includes a pushing mechanism 123, which is used to push the magnetic medium to the demagnetizing area. The demagnetizing module 130 is equipped with a magnetic field strength sensor 131, which is configured to detect the magnetic field strength of the demagnetizing area.
[0049] The controller 160 is electrically connected to the magnetic field strength sensor 131 and is configured to control the demagnetization module 130 to demagnetize the magnetic medium.
[0050] Outbound module 170 is configured to receive the demagnetized magnetic medium.
[0051] The inlet module 120, demagnetization module 130, controller 160, and outlet module 170 are located inside the demagnetization equipment 100. The inlet module 120 and outlet module 170 are located on the inner sides of two opposite side walls of the demagnetization equipment 100, with the demagnetization module 130 positioned between them. The controller 160 collects data from various sensors, analyzes and summarizes this data, controls the internal system operation, performs self-checks on various sensors, and provides feedback to external systems. During operation, the magnetic medium to be demagnetized is inserted face up into the inlet port 122. The inlet port 122 has spring structures at the top and bottom to hold the magnetic medium in place. Upon sensing the insertion, the magnetic medium is automatically drawn in, and the inlet port 122 automatically closes. After being drawn in, the magnetic medium is pushed to the demagnetization area by the pushing mechanism 123, where the controller 160 controls the capacitor discharge to perform demagnetization. After being demagnetized, the magnetic medium is pushed to the discharge module 170 by the pushing mechanism 123. The controller 160 controls the door to open, and the magnetic medium exits from the discharge port 172.
[0052] As an alternative, this application provides a demagnetizing device 100, which further includes an encryption module 110, which is electrically connected to a controller 160; the inlet 122 is provided with a door, and the controller 160 is configured to control the opening of the door according to the information input by the encryption module 110; during the demagnetizing process of the demagnetizing module 130 on the magnetic medium, the door closes the inlet 122.
[0053] As an alternative, this application provides a demagnetizing device 100, wherein the encryption module 110 includes at least one of a fingerprint recognition module, a face recognition module, and a retinal recognition module.
[0054] The encryption module 110 can be set independently, or it can be located in the touchscreen area 190, or connected to other terminals via the wireless module 150. The encryption module 110 can restrict the operator of the demagnetizing device 100, improving data security. The encryption module 110 can be set to register one of three types of fingerprints, faces, or retina images, or two or three of them simultaneously. After the operator turns on the device, they must first be identified by the encryption module 110. If a fingerprint is recognized by the encryption module 110 as already registered, the touchscreen 190 or the remotely connected interface via the wireless module 150 will become operable. Simultaneously, the inlet 122 will open in a self-locking state, allowing the magnetic medium to enter. During the demagnetizing phase, the inlet 122 will close, physically isolating the magnetic field.
[0055] As an alternative, this application provides a demagnetizing device 100, in which an image acquisition unit 121 is provided in the inlet module 120, and the image acquisition unit 121 is electrically connected to the controller 160; the image acquisition unit 121 is located on the top of the inlet module 120.
[0056] The image acquisition unit 121 is configured to acquire image information of the magnetic medium and send it to the controller 160, enabling the controller 160 to identify the type of magnetic medium based on the image information. The image acquisition unit 121 can be a video sensor with infrared functionality, deployed at the top center of the loading module 120 to ensure no blind spots in the video feed. After the image information is sent to the controller 160, the controller 160 extracts information such as the serial number from the image. By comparing the image information uploaded by the video sensor with the recorded magnetic medium information, the controller 160 can determine the type of magnetic medium.
[0057] As an alternative, this application provides a demagnetizing device 100, wherein the pushing mechanism 123 includes a driving unit, a transmission unit, and a support member. The support member is used to carry the magnetic medium. The output end of the driving unit is connected to the transmission unit and drives the transmission unit to move the support member, so that the support member moves the magnetic medium from the inlet 122 to the demagnetizing area.
[0058] The transmission unit can be a conventional guide rail, conveyor belt, gear, or chain, or a sloping chute. The choice of form is not limited, depending on the actual operability, ease of installation, and economy. The transmission unit connects the inlet module 120 and the demagnetization module 130 area. The support component can be a component with a receiving groove or a conveyor belt. The drive component is electrically connected to the controller 160 and drives the support component to move on the transmission unit when it receives a command.
[0059] As an alternative approach, this application provides a demagnetizing device 100, with an inlet module 120 and an outlet module 170 located at opposite ends of the demagnetizing device 100. One end of the travel of the support member is opposite to the inlet module 120, and the second end of the travel of the support member is opposite to the outlet module 170. After the magnetic medium is demagnetized, the support member is configured to move the magnetic medium from the demagnetizing area to the outlet module 170.
[0060] The inlet module 120 and the outlet module 170 are located on the inner sides of two opposite sides of the demagnetizing device 100, respectively. The inlet port 122 and the outlet port 172 are respectively opened on the side walls of two opposite sides of the demagnetizing device 100. The moving stroke of the support connects the inlet port 122 and the outlet port 172 and crosses the demagnetizing area.
[0061] As an optional approach, this application provides a demagnetizing device 100, comprising multiple magnetic field strength sensors 131, with the demagnetizing module 130 having magnetic field strength sensors 131 at its top, middle, and bottom. The placement of the magnetic field strength sensors 131 in multiple locations allows for better detection of magnetic field changes during the demagnetizing process, improving reliability and safety. The number of magnetic field strength sensors 131 at each location of the demagnetizing module 130 can be determined according to actual needs.
[0062] As an alternative, this application provides a demagnetizing device 100. The dispensing module 170 has an dispensing port 172, and an inkjet printer 171 is installed within the dispensing module 170. When the magnetic medium moves to the dispensing port 172, the inkjet printer 171 faces the magnetic medium and is used to print demagnetizing information on the surface of the magnetic medium. The inkjet printer 171 is connected to a controller 160 and receives demagnetizing information from the controller 160. If the controller 160 transmits a successful demagnetizing message, the pushing structure pushes the magnetic medium to the dispensing port 172, the inkjet printer 171 prints the demagnetizing information on the medium surface, and then the magnetic medium automatically exits the dispensing unit, completing the demagnetizing process normally. The demagnetizing information includes operator information, demagnetizing time, the demagnetizer's serial number, and whether demagnetizing was successful. If the controller 160 transmits a demagnetizing failure message, the pushing structure directly sends the demagnetized medium out of the dispensing unit, and the inkjet printer 171 does not operate.

The power module 180 is configured to charge the energy storage module 140, and the energy storage module 140 is used to discharge to the demagnetizing module 130, thereby causing the demagnetizing module 130 to generate a strong magnetic field. The energy storage module 140 may be a capacitor, and during the demagnetizing phase, the charge stored in the capacitor is discharged to generate an instantaneous strong magnetic field to demagnetize the magnetic medium.
[0064] The power module 180 is equipped with a power sensor 181, which collects power information and transmits it to the controller 160. The energy storage module 140 is equipped with a charge / discharge sensor 141, which collects the status information of the energy storage module 140 and transmits it to the controller 160.
