Waterproof structure and control method of terminal equipment with built-in barometer

Abstract

The invention discloses a waterproof structure and a control method of a terminal equipment with a built-in barometer, relates to the field of terminal equipment, and solves the waterproof and breathable problem of the terminal equipment. The specific solution is: a waterproof structure of a terminal device with a built-in barometer, the waterproof structure is a built-in cavity of the terminal device, and the waterproof structure has an opening on the shell of the terminal device, so that the air pressure in the waterproof structure communicates with the external air pressure, waterproof There is a barometer inside the structure, a dust-proof net is set between the opening and the barometer, and a waterproof screen is set between the dust-proof net and the barometer, and a water drop detection device is set between the waterproof screen and the barometer. A control valve is arranged between the device and the barometer; the water drop detection device is electrically connected to the control valve, and when the water volume detected by the water drop detection device reaches the water volume threshold, the control valve is closed. The present invention is applicable 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. ...

AI Technical Summary

Problems solved by technology

[0005] In the process of realizing the above technical solution, the inventor found that the prior art has at least the following problems: for the IPX5 waterproof grade, when the mobile phone terminal falls into the water, the waterproof requirement cannot be met; for the IPX7 waterproof grade, due to the waterproof membrane solution The aperture is too small and the ventilation is slow, which will cause a delay in the transmission of air pressure inside and outside the mobile phone, which is not conducive to the real-time measurement of the vertical height of the mobile terminal location
