Water detecting system and related method of portable electric device
First Claim
1. A water detecting system of a portable electric device, for detecting water entering the portable electric device, comprising:
- a housing;
an electronic circuitry board of the portable electric device disposed inside the housing;
a battery electrically connected to the electronic circuitry board for providing electrical power to the electronic circuitry board;
at least one pair of electric terminals, the pair of electric terminals comprising one positive terminal and one negative terminal located in close proximity to the positive terminal, wherein when the pair of electric terminals are electrically conducted by contacting the water, a current runs through the pair of electric terminals;
a current detector electrically connected to the pair of electric terminals for detecting if the current running through the pair of electric terminals exceeds a threshold level; and
a switch connected to the current detector and the battery for disconnecting the battery from the electronic circuitry board when the current exceeds the threshold level.

Abstract
A water detecting system of a portable electric device comprises a housing, an electronic circuitry board, a battery electrically connected to the electronic circuitry board for providing electrical power to the electronic circuitry board, and at least one pair of electric terminals, the pair of electric terminals comprising one positive terminal and one negative terminal located in close proximity to the positive terminal. When the pair of electric terminals are electrically conducted, a current runs through the pair of electric terminals. The water detecting system also comprises a current detector electrically connected to the pair of electric terminals for detecting if the current running through the pair of electric terminals exceeds a threshold level, and a switch connected to the current detector and the battery for disconnecting the battery from the electronic circuitry board when the current exceeds the threshold level.
