Seal detecting device and means thereof

A seal detecting device for detecting an electronic device, wherein an outer case of the electronic device is provided with a through hole, an inner side of the outer case is connected to an outer side of the outer case through the through hole, the seal detecting device comprising:

• a container including an accommodating space, the accommodating space having an opening, the accommodating space communicating with outer space and having a cover disposed thereon to cover the opening so as to form an airtight container;
• when being under detection, the electronic device being placed inside the airtight container, the cover covering the through hole, one of the inner side and outer side of the outer case being an gas supply side, and the other side being an detecting side;
• a compressed gas supplying device connected to the gas supply side of the electronic device inside the airtight container to provide compressed gas;
• and
• a flowmeter connected to the detecting side of the outer case of the electronic device to detect a flow so as to detect if there is a leakage on the outer case of the electronic device.
