Abstract

The invention relates to the technical field of electronic devices, and discloses a mobile terminal and a method for preventing water inflow damage of the mobile terminal. In the invention, the mobile terminal comprises a housing, a circuit board, a processor, a power management chip and at least one short circuit detector used for detecting whether water enters from an open pore position of the housing; the short circuit detector comprises a conducting wire and a water swelling part installed on the circuit board; the water swelling part corresponds to the open pore position of the housing; the conducting wire is connected between a voltage output end of the power management chip and a GPIO interface of the processor, and when the water swelling part is subjected to water inflow at the open pore position of the housing, the conducting wire is disconnected or connected. In the embodiment, the water swelling part quickly swells in water to disconnect or connect the conducting wire, the voltage change of the circuit where the conducting wire is located is detected to judge whether the mobile terminal is subjected to water inflow, whether the mobile terminal is subjected to water inflow can be judged by a simple circuit without using an additional sensor, and thus the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a mobile terminal and a method for preventing water damage to the mobile terminal. Background technique [0002] Nowadays, anti-drop, anti-pressure, dust-proof and other protection technologies for mobile terminals (such as mobile phones, tablets, laptops, wearable devices, etc.) Damage caused by pressure or dust ingress during daily use. However, the problem that attracts the most attention from users at present is that when the mobile terminal accidentally enters water, the internal motherboard of the mobile terminal will burn the electronic components due to a short circuit, making the mobile terminal unable to use normally. [0003] There are many conventional waterproof designs for mobile terminals. One of the waterproof designs is to install a waterproof device on the mobile terminal. As long as it is equipped with a specially designed waterproof device, it ca...
