Claim of US Patent No. 9,345,159

1. A water-proof structure provided with an internal barometer for a terminal device, wherein the water-proof structure is
an internal cavity of the terminal device, the water-proof structure is provided with an opening on a casing of the terminal
device so that a barometric pressure inside the water-proof structure is in communication with an external barometric pressure,
the water-proof structure comprising:
the internal barometer arranged inside the water-proof structure;
a dust-proof net arranged between the opening and the internal barometer;
a water-proof mesh net arranged between the dust-proof net and the internal barometer;
a water drop detection device arranged between the water-proof mesh net and the internal barometer; and
a control valve arranged between the water drop detection device and the internal barometer, wherein the water drop detection
device is electrically connected to the control valve and is configured to cause the control valve to close when a water volume
detected by the water drop detection device reaches a water volume threshold value.
