All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Referring to fig. 1, a schematic diagram of a part of elements of a mobile terminal in an embodiment of the present invention is shown, where in fig. 1:

the mobile terminal 100 includes a power module 10 and a protection module 20.

One end of the protection module 20 is connected to the designated pin 11 of the power module 10, and the other end is connected to the first ground terminal. And, the designated pin 11 is also connected to the second ground terminal 32 through the bypass capacitor 12.

When the mobile terminal enters the liquid, the protection module 20 controls the designated pin 11 to be conducted with the first ground terminal 31.

In summary, the mobile terminal in the embodiment of the present invention can control the specified pin of the power module to be conducted with the ground terminal after the liquid is fed, so as to avoid damaging the internal circuit and components of the mobile terminal, and reduce the property loss of the user.

Example two

Specifically, in an embodiment of the present invention, the protection module 20 includes a soluble conductive crystal therein. In one embodiment, the soluble conductive crystal is a crystalline salt Nacl.

In addition, in one embodiment of the present invention, when the soluble conductive crystal in the protection module 20 contacts the liquid, the protection module 20 conducts the designated pin 11 and the first ground terminal 31. Specifically, when the soluble conductive crystal in the protection module 20 contacts the liquid, it reacts with the liquid, so as to conduct the conductor between the designated pin 11 and the first ground terminal 31, and to conduct the designated pin 11 with the first ground terminal 31, thereby reducing the voltage value of the designated pin 11. Meanwhile, the designated pin 11 is connected with the bypass capacitor 12, so that the decrease of the voltage value of the designated pin 11 will cause the decrease of the electric quantity value of the bypass capacitor 12, thereby triggering the automatic shutdown of the mobile terminal.

In another embodiment of the present invention, when the protection module 20 detects that the humidity is greater than the preset value, the protection module 20 controls the designated pin 11 to be connected to the first ground terminal 31. Specifically, when the humidity inside the mobile terminal is greater than a preset value, the soluble conductive crystal reacts with water molecules in the mobile terminal, so that a conductor is arranged between the designated pin 11 and the first ground terminal 31, the designated pin 11 is conducted with the first ground terminal 31, and the mobile terminal is triggered to be automatically turned off.

In addition, in an embodiment of the present invention, the power module 10 is a power management integrated circuit (ic) (integrated circuit), and the pin 11 is designated as an analog power bypass AVDD _ BYP pin.

In another embodiment of the present invention, the protection module 20 is a waterproof sticker located on a main board of the mobile terminal.

Fig. 2 is a schematic structural diagram of a waterproof sticker 200 according to an embodiment of the present invention. In fig. 2:

one end of the waterproof tape 200 covers the exposed copper foil of the designated pin 11, and the other end covers the exposed copper foil of the first ground terminal 31.

In one embodiment of the present invention, the waterproof sticker 200 includes a surface layer 21, a discoloring layer 22, and a soluble conductive crystal between the surface layer 21 and the discoloring layer 22, and the copper-exposed copper foil of the designated pin 11 (as the left-side shaded portion in fig. 2) and the copper-exposed copper foil of the first ground terminal 31 (as the right-side shaded portion in fig. 2) are located below the discoloring layer 22. Specifically, the soluble conductive crystals are attached to the lower surface of the surface layer 21 and the upper surface of the color-changing layer 22. Wherein, there is not any direct contact area between surface layer 21 and the look layer 22, therefore, the clearance between surface layer 21 and the look layer 22 can hold liquid to pass through after the mobile terminal feed liquor to make liquid and soluble conductive crystal fully react, and then form the conductor fast. In another embodiment of the present invention, one end of the lower surface of the color changing layer 22 is adhered to the copper exposed copper foil of the designated pin 11, and the other end is adhered to the copper exposed copper foil of the first ground terminal 31. The adhesion method can be performed by a medium such as a double-sided tape, which is not limited in the present invention. In addition, in an embodiment of the present invention, the color-changing layer 22 can change color when encountering a liquid, and a specific implementation manner can be implemented by using an embodiment in the prior art, which is not described herein again.

In the embodiment of the invention, when the switch module 40 is triggered, the switch module 40 turns on the power terminal 13 and the third ground terminal 33. Specifically, in the embodiment of the present invention, the mobile terminal 100 includes a trigger mechanism corresponding to the switch module 40, and in one embodiment, the trigger mechanism may be a designated button disposed on the mobile terminal, and when the mobile terminal detects a pressing operation acting on the designated button, the trigger mechanism may be activated to close the switch module 40. The designated button may be disposed in an opening on the middle frame of the mobile terminal 100, so as to avoid user's misoperation.
