Destruction device for destroying memory in communication equipment

The present invention relates to a destruction device for destroying the memory in the communication equipment, and in particular to a destruction device for destroying the memory in the communication equipment that can simplify and confirm the effect of destroying the data in the memory of the communication equipment when it is obsolete. .

Due to the rapid development of communication technology, the proportion of people using communication equipment is increasing. Among communication equipment, mobile phones (mobile communication devices) are particularly popular among consumers, and it has become common for everyone to have one mobile phone. Because mobile phones have more and more functions, the use of mobile phones is not only used for communication, but also for electronic payment of consumption and storage of various private information. ． ． ． They all rely on mobile phones.

The reason why mobile phones can provide various convenient uses is mainly achieved by the memory inside the mobile phone, which means that users can store various private information and communication data in the memory for later use. However, mobile phones are still man-made electronic products and basically have a certain service life. Or due to the improvement of various application software used with the mobile phone, the basic application software of the mobile phone itself cannot be improved and must be replaced with new ones. . After the mobile phone is replaced with a new one, the electronic components inside the old mobile phone can be recycled and reused. Therefore, the data originally stored in the memory of the mobile phone must be deleted to ensure that personal private information is not leaked. .

When mobile phones are obsolete, data in the memory is usually deleted by formatting or deleting programs on the phone itself. However, as we all know, the deletion of the phone itself It is basically impossible to delete the data in the memory completely or conclusively by deleting the program. Therefore, to truly delete the data in the mobile phone memory, it is best to disassemble the phone itself and directly smash the memory; however, This kind of project of disassembling a mobile phone and then smashing the memory by oneself is not something that ordinary consumers can do.

Therefore, how to provide a destruction device for destroying the memory in communication equipment, which can destroy the memory easily and safely without dismantling the communication equipment, has become an urgent issue that manufacturers of destruction devices for destroying the memory in communication equipment need to solve. .

The main purpose of the present invention is to provide a destruction device for destroying the memory in the communication equipment, thereby overcoming the shortcoming of the conventional communication equipment that cannot reliably destroy the data in the memory.

To this end, the main technical means of the present invention is to provide a destruction device for destroying the memory in communication equipment. The destruction device has at least one high-voltage generating circuit unit to generate high-voltage power. When the destruction device passes through an electrical connector After being electrically connected to the communication equipment, the high-voltage current generated by the high-voltage generating circuit unit is input into the communication equipment, so that the memory in the communication equipment is shocked by the high-voltage power supply and is destroyed and cannot be read again.

The effect that the present invention can achieve through the main technical means is that it can simplify and confirm the destruction of data in the memory of the communication equipment when it is obsolete.

As shown in FIG. 1 , the rectifier unit 12 is mainly used to convert the external power input from the power supply unit 11 into direct current backup, which means to convert the 110V (volt voltage) alternating current (AC) input into the destruction device 1 from the outside. Convert to direct current (DC).

As shown in Figure 1, the first relay unit 13 is electrically connected to the high voltage generating circuit unit 14 and the main control circuit unit 16, whereby the main control circuit unit 16 can determine whether the first relay unit 13 is conductive, that is, the Whether the first relay unit 13 can input the power converted into direct current into the high-voltage generating circuit unit 14 to increase the voltage; at the same time, the disconnection of the first relay unit 13 can prevent the rectifier unit 12 from converting failure and causing the overall The destruction device 1 is damaged, thereby ensuring the usability of the destruction device 1 .

As shown in Figure 1, the high-voltage generating circuit unit 14 mainly inputs the power converted into direct current from the first relay unit 13 to increase the voltage value. The high-voltage generating circuit unit 14 of the present invention can specifically be a DC-DCConverter (converter). It is implemented with the BOOST (topological circuit) architecture of the converter, but is not limited to this conversion and boost architecture; the input high-voltage generating loop unit 14 is a closed-loop control system, thereby stably outputting high-voltage power.
