Abstract
The utility model relates to a device for destroying information in a storage medium, which comprises a power supply input end, a coil, a first electronic switch, a boosting rectifier, a capacitor and a second electronic switch. The coil is internally provided with a magneto-dependent sensor which is connected with a magnetic field signal output line. The first electronic switch is arranged between the boosting rectifier and the power supply input end. The power supply input end, the first electronic switch, the boosting rectifier and the capacitor form a charging return circuit. The capacitor, the coil and the second electronic switch form a discharge return circuit. The second electronic switch is arranged between the coil and the capacitor. The device for destroying information in the storage medium has the advantages of low noise, high reliability and long service life. As high voltage and large working current are adopted, the magnetic field is stable and reliable. At the same time, a magnetic field sensor is buried in the coil, so that the magnetic field in the coil can be monitored conveniently.
Description
Technical field
The utility model relates to a kind of harmless treatment equipment of storage medium, is specifically related to a kind of equipment for information on the destruction of stockpiles medium.
Background technology
Along with making rapid progress of electronic technology, information storage medium is also varied, traditional computer hard disc for example, portable hard drive, USB flash disk, the large-capacity storage media such as solid state memory disc, for another example conventional softer storage devices such as CD, disk and electronics egative film, above-mentioned information storage medium have wherein comprised a large amount of state secrets and enterprise secret as the storage medium of computer or electronic installation, must after it is discarded, carry out safer destroying, in case close the leaking of stop machine.
The mode of traditional destroying information storage medium is the material composition according to electronic storage medium, and it is carried out respectively pulverization process.For example for computer hard disc, portable hard drive, solid state memory disc etc. contain the storage medium of hard metal shell, destroy accordingly.But destroy device in the market often has pulverizing not thorough, sometimes also can pulverize less than the important problems such as storage chip.
Therefore, for avoiding the problems referred to above, necessaryly provide a kind of structure improved equipment for information on the destruction of stockpiles medium that has, to overcome described defective of the prior art.
The utility model content
For addressing the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, and cost is low and can thoroughly ruin the equipment of information on the pin storage medium.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of equipment for information on the destruction of stockpiles medium, and it comprises power input, coil, the first electronic switch, boost rectifier, capacitor and the second electronic switch; Wherein, be provided with a magneto-dependent sensor in the described coil, on magneto-dependent sensor, be connected with the field signal output line; Described the first electronic switch is arranged between boost rectifier and the power input; Described power input, the first electronic switch, boost rectifier and capacitor form charge circuit; Described capacitor, coil and the second electronic switch form discharge loop; Described the second electronic switch is arranged between coil and the capacitor.
Equipment for information on the destruction of stockpiles medium of the present utility model further is set to: described the first electronic switch is specially bidirectional triode thyristor, relay or A.C. contactor.
Equipment for information on the destruction of stockpiles medium of the present utility model further is set to: described the second electronic switch is specially controllable silicon or IGBT electronic switch.
Compared with prior art, the utlity model has following beneficial effect: the equipment for information on the destruction of stockpiles medium of the present utility model information on the pin storage medium of can thoroughly ruining can reduce the noise of switch, improve reliability, increase the service life, and can realize high pressure, large current work, improve magnetic field; Simultaneously, by burying in coil magnetic field sensor underground, thereby be convenient to detection and the amplification of coil internal magnetic field.
Description of drawings
Fig. 1 is the schematic diagram for the equipment of information on the destruction of stockpiles medium of the present utility model.
The specific embodiment
See also shown in the Figure of description 1, the utility model is a kind of equipment for information on the destruction of stockpiles medium, and it is formed by the assembling of the elements such as power input 1, coil 2, the first electronic switch 3, boost rectifier 4, capacitor 5 and the second electronic switch 6.
Wherein, the alternating current of described power input 1 input 220V or 110V is for equipment work provides electric energy.
One end of described coil 2 offers an opening 21, and storage medium can insert in the coil 2 by this opening 21, by the high-intensity magnetic field of coil 2 generations the information on the storage medium is thoroughly destroyed.In described coil 2, be provided with a magneto-dependent sensor 22, on magneto-dependent sensor 22, be connected with field signal output line 23.This magneto-dependent sensor 22 is used for measuring magnetic field, and it is specially the Hall element of four ends, the perhaps mistor of four ends, or the search coil of two ends.
Described the first electronic switch 3 is arranged between boost rectifier 4 and the power input 1, and it is specially bidirectional triode thyristor, relay or A.C. contactor.
Described power input 1, the first electronic switch 3, boost rectifier 4 and capacitor 5 form charge circuit; Described capacitor 5, coil 2 and the second electronic switch 6 form discharge loop.
Described the second electronic switch 6 is arranged between coil 2 and the capacitor 5, and it is specially controllable silicon or IGBT electronic switch, also can be other electronic switching device.
The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
