Abstract

The invention discloses a waterproof structure of a barometer built-in terminal device and a control method, relates to the field of terminal devices, and realizes the water resistible and breathable effects of the terminal device. The specific scheme is as follows: the waterproof structure of the barometer built-in terminal device is a built-in cavity of the terminal device; an opening is formed in a housing of the terminal device to allow air pressure in the waterproof structure to communicate with the external air pressure; the barometer is arranged inside the waterproof structure; a dust screen is arranged between the opening and the barometer; a waterproof screen is arranged between the dust screen and the barometer; a water drop detecting device is arranged between the waterproof screen and the barometer; a control valve is arranged between the water drop detecting device and the barometer; the water drop detecting device is electrically connected with the control valve; when the water drop detecting device detects that the water volume is up to the water volume threshold value, the control valve is turned off. The waterproof structure of the barometer built-in terminal device and the control method can be applied to various terminals.

Description

technical field [0001] The present invention relates to the field of terminal equipment, in particular to a waterproof structure of a terminal equipment with a built-in barometer, the terminal equipment and a control method. Background technique [0002] With the advancement of technology, the waterproof and dustproof requirements of mobile terminals are getting higher and higher. At present, among the internationally accepted IP (international protection, international protection) XX waterproof and dustproof grades, the first X means: dustproof grade, and the larger the X, the higher the dustproof grade. The second X means: waterproof level, the larger the X, the higher the waterproof level. [0003] In current mobile terminal products, a barometer may be built in to measure the vertical height of the mobile terminal. In order to ensure the sensitivity of the barometer, it is necessary to maintain the air permeability between the barometer and the external environment. ...
