Referring to FIG. 1 and FIG. 2 simultaneously, the portable electronic device 100 includes an airbag 10, an inflator 20, a housing 30, a water immersion detecting device 50, and a control device 70.

The air bag 10 can be in both folded and inflated states. The airbag 10 is not in the portable electronic device 100 When it is immersed in water, it is in a folded state, and after the portable electronic device 100 is immersed in water, it is in an inflated state, so that the portable electronic device 100 can be protected by the airbag 10 after falling into the water.

The inflator 20 is coupled to the air bag 10 for inflating the air bag 10 to deploy the air bag 10 when the portable electronic device 100 is immersed in water.

The housing 30 is provided with a receiving slot 302 and a cover 304 for closing the receiving slot 302. When the airbag 10 is in the folded state, the airbag 10 is received in the receiving slot 302, and can be unfolded by the cover 304 extending out of the receiving slot 302 during inflation.

The water immersion detecting device 50 is configured to detect whether the portable electronic device 100 is immersed in water and emit a detection signal when the portable electronic device 100 is immersed in water. The water immersion detecting device 50 may be a water immersion sensor.

The control device 70 is connected to the water immersion detecting device 50 and the inflating device 20, respectively, for receiving the detection signal from the water immersion detecting device 50, and controlling the inflating device 20 to inflate the airbag 10 according to the received detection signal, so that the airbag 10 is inflated. The state so that the portable electronic device 100 is protected from the airbag 10 after falling into the water does not quickly sink into the bottom of the water.

Additionally, the inflator 20 includes a compressed gas container 22 and a switch 24. When the control device 70 receives the detection signal, the control device 70 opens the switch 24 to diffuse the compressed gas in the compressed gas container 22 to inflate the air bag 10.

As shown in FIG. 3, in another embodiment, the inflator 20 includes an igniter 26 and an aerating agent 28. When the control device 70 receives the detection signal, the control device 70 detonates the igniter 26 to generate heat. The aerating agent 28 typically employs a solid or liquid fuel, and the heat generated by the ignition of the igniter 26 decomposes the aerating agent 28, which produces a gas to inflate the balloon 10.

After the portable electronic device 100 is immersed in water, the control device 70 controls the inflator 20 to inflate the airbag 10 to bring the airbag 10 into an inflated state, so that the portable electronic device 100 is protected by the airbag 10 after falling into water. Quickly sink into the water.

As shown in FIG. 4, a flowchart of a method for protecting a water drop of the portable electronic device 100 includes the following steps.

In step S802, it is detected whether the portable electronic device 100 is immersed in water. If the portable electronic device 100 is immersed in water, the process proceeds to step S804. If the portable electronic device 100 is not immersed in water, the process returns to step S802.

In step S804, a detection signal is generated.

Step S806, receiving the detection signal and controlling the inflator 20 to inflate the airbag 10, so that the airbag 10 is in an inflated state, so that the portable electronic device 100 can be protected by the airbag 10 after falling into the water.

As shown in FIG. 5, step S806 receives the detection signal and controls the inflator 20 to inflate the airbag 10 as follows:

In step S8062, the detection signal is received and the switch 24 of the inflator 20 is opened to diffuse the compressed gas in the compressed gas container 22 to inflate the airbag 10.

As shown in FIG. 6, in another embodiment, step S806 receives the detection signal and controls the inflator 20 to inflate the airbag 10, including the following steps:

In step S8064, the detection signal is received and the igniter 26 is detonated to generate heat.

In step S8066, the heat generated after the igniter 26 is detonated causes the aeration agent 28 to decompose and generate gas to inflate the airbag 10.

The portable electronic device 100 is configured to prevent the inflator 20 from inflating the airbag 10 when the portable electronic device 100 is immersed in water, so that the airbag 10 is in an inflated state, so that the portable electronic device 100 is subjected to the airbag after falling into the water. The protection of 10 will not sink to the bottom quickly.
