## Background
BACKGROUND
1. Field of the Invention
The present invention relates to portable electronic devices, and particularly to a portable electronic device with a maintenance capability.
2. Description of Related Art
Nowadays, portable electronic devices such as mobile phones, laptop computers and personal digital assistants (PDA) are widely used. Similarly to electronic devices, when a portable electronic device has been used for a long time, many components of the portable electronic device may be gradually worn out. For example, the communicating function of the antenna of the portable electronic device can be degraded by rust formed thereon, and the chips of the portable electronic device may be damaged by oxidation. Therefore, these components may often need to be maintained, such as being treated by antioxidants or cleansers.
When electronic devices are maintained, they usually need to be taken apart for maintaining the inner components thereof. However, many portable electronic devices are very small in size. The portable electronic devices are generally difficult to be disassembled, and it is difficult to manually maintain the inner components of the portable electronic devices because of their small size. Additionally, frequent disassembling the portable electronic devices for maintaining may damage their mechanical structures.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT
Referring to FIG. 1 and FIG. 2, a portable electronic device 100 with maintenance capability, according to an exemplary embodiment, is provided. While the exemplary portable electronic device 100 is a mobile phone, it can also be a personal digital assistant (PDA), a laptop computer, etc.
The portable electronic device 100 includes a cover 10, at least one treatment element 20 and a circuit board 30. The cover 10 is an approximately rectangular board, which can be a part of the housing of the portable electronic device 100.
The treatment element 20 is a sheet made of absorptive materials, such as foam, sponge or active carbon, etc. The treatment element 20 is attached to the cover 10. The cover 10 defines at least one injecting hole 12 communicating with the treatment element 20. In the exemplary portable electronic device 100, there are two treatment elements 20 and two injecting holes 12 respectively corresponding thereto.
The circuit board 30 has a plurality of circuit components 33 such as chips, antenna or amplifiers mounted thereon. A shield 35 is mounted on the circuit board 30 and shields the circuit components 33 therein. The shield 35 is made of transcalent materials such as metal and has a plurality of meshes 351 defined therein.
In assembly, the cover 10 is assembled to the circuit board 30. The treatment element 20, the shield 35 and the circuit components 33 shielded in the shield 35 are all placed between the cover 10 and the circuit board 30, and the treatment element 20 is aligned with the shield 35 and the circuit components 33 shielded therein. Volatile treatment liquids, such as antioxidants, cleansers or perfumes, are injected into the injecting hole 12, and then absorbed and stored by the treatment element 20. Additionally, if too much liquid is injected into the injecting hole 12 and overflows, the shield 35 separating the circuit components 33 with the treatment element 20 can protect the circuit components 33 from dampness.
When the portable electronic device 100 is used, the circuit components 33 works and generates heat. The heat is conducted by the shield 35 and then heats the adjacent treatment element 20. As the temperature of the treatment element 20 increases, the volatile treatment liquids stored in the treatment element 20 volatilize. Thus, gaseous maintaining matters can enter the shield 35 through the meshes 351 and maintain the circuit components 33, and can also maintain other components of the portable electronic device 100 out of the shield 35. When the treatment liquids in the treatment element 20 are used up, new liquids can be supplied to the treatment element 20 through the injecting hole 12.
Understandably, the treatment element 20 can also be a changeable solid substance made of solid maintaining matters or comprising solid/liquid maintaining matters, so as the maintaining matters can volatilize when the treatment element 20 is heated. Correspondingly, the injecting holes 12 can be omitted. When the maintaining matters are used up, a new treatment element 20 can replace the previous one.
The exemplary portable electronic device 100 can be automatically maintained when it is in use, thus the conventional manual maintaining operations can be omitted. Further, the portable electronic device 100 need not be disassembled in every time of maintaining, which protects the mechanical structure of the portable electronic device 100.
It is to be further understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
