Water-proof structure provided with internal barometer for terminal device and method for controlling a water-proof structure

摘要

A water-proof structure has an internal barometer for a terminal device. 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. Abarometer is arranged inside the water-proof structure. A water drop detection device is arranged between a water-proof mesh net and the barometer. The water drop detection device is electrically connected to a control valve, and when a water volume detected by the water drop detection device reaches a water volume threshold value, the control valve is closed.
