Abstract

An electronic device includes a housing, a water-repellent structure and a draining structure. The housing has at least a first air port. The water-repellent structure is connected to the housing and includes at least one draining port. The water-repellent structure and the housing cooperatively define a water-repellent chamber. The draining structure is disposed in the water-repellent chamber for reducing the possibility of splashing the fluid into the water-repellent chamber and guiding the fluid which is splashed into the water-repellent chamber to be discharged out through the draining port.

Claims

1. An electronic device comprising:

a housing having at least one first air port;

a water-repellent structure connected to said housing and including at least one draining port, wherein said water-repellent structure and said housing cooperatively define a water-repellent chamber; and

a draining structure disposed in said water-repellent chamber for preventing the fluid from being splashed into said water-repellent chamber and guiding the fluid which is splashed into said water-repellent chamber to be discharged out through said draining port.

2. The electronic device according to claim 1 being selected from a group consisting of a power adapter and a power supply apparatus.

3. The electronic device according to claim 1 wherein said housing further includes a partition plate extended from an inner surface thereof.

4. The electronic device according to claim 3 further comprising a sheltering member, wherein said sheltering member includes a protrusion plate, which is connected to said draining structure and selectively aligned with said partition plate such that said first air port is defined between said partition plate and said protrusion plate.

5. The electronic device according to claim 1 wherein said water-repellent structure includes plural tilt plates, which are parallel with each other, wherein a plurality of second air ports are defined between every two adjacent tilt plates and between one of said tilt plates and an inner surface of said housing such that an air flow is inputted into and outputted from said water-repellent chamber through said first air port and said second air ports, and said draining port is defined between one of said tilt plates and said draining structure.

6. The electronic device according to claim 5 wherein said inner surface of said housing is a slant surface for guiding the fluid which is splashed into said water-repellent chamber to be discharged outside said housing through said second air ports.

7. The electronic device according to claim 1 wherein said water-repellent structure includes a cover structure having at least a second air port, and a gap is defined between said cover structure and said housing such that air flow is transferred through said at least one first air port, said at least one second air port and said gap.

8. The electronic device according to claim 7 wherein said draining structure include a first side plate and a second side plate of said cover structure, and said at least one draining port includes at least one first draining port in said first side plate and at least one second draining port in said second side plate, wherein said first side plate and said second side plate have first and second slant surfaces for guiding the fluid which is splashed into said water-repellent chamber to be discharged out through said at least one first draining port and said at least one second draining port.

9. The electronic device according to claim 7 wherein said at least one first air port is disposed in a side plate of said housing, and the heat generated from said electronic device is dissipated away said electronic device through said at least one first air port.

10. The electronic device according to claim 1 wherein said water-repellent structure includes at least one cylindrical element, and said cylindrical element has a baffle for partially hindering said fluid from entering an inner portion of said housing.

11. The electronic device according to claim 10 wherein said draining structure is a slant surface on an inner wall of said cylindrical element for guiding the fluid which is splashed into said water-repellent chamber to be discharged out through said at least one draining port.

12. The electronic device according to claim 11 further comprising:

a ring-shaped structure protruded from a surface of said housing and enclosing said at least one draining port for partially hindering said fluid from entering said at least one cylindrical element; and

a cover member enclosing said ring-shaped structure, wherein a first side plate of said cover member is connected to said housing, and a gap is formed between said housing and a second side plate of said cover member, such that an air flow is transferred through said at least one first air port, said at least one draining port and said gap.

13. The electronic device according to claim 1 wherein said housing includes an indentation portion and plural protrusion rings at a lateral side thereof, said protrusion rings being protruded from said lateral side of said housing and confined within said indentation portion.

14. The electronic device according to claim 13 wherein said water-repellent structure includes a cover structure sheltering said indentation portion, wherein said draining structure includes a slant surface of a first side plate of said cover structure, a gap is defined between said cover structure and said housing for guiding the fluid which is splashed into said water-repellent chamber to be discharged out through said gap, a second side plate of said cover structure is connected to said housing and includes said at least one draining port such that air flow is transferred through said at least one first air port and said at least one draining port.

15. A process of fabricating an electronic device, comprising steps of:

providing a housing having at least one first air port;

providing a water-repellent structure and a draining structure, wherein said water-repellent structure includes at least one draining port; and

connecting said water-repellent structure with said housing to form a water-repellent chamber, and placing said draining structure in said water-repellent chamber, thereby preventing the fluid from being splashed into said water-repellent chamber and guiding the fluid which is splashed into said water-repellent chamber to be discharged out through said at least one draining port.

16. The process according to claim 15 wherein said water-repellent structure includes a cover structure having at least one second air port, and a gap is defined between said cover structure and said housing such that air flow is transferred through said at least one first air port, said at least one second air port and said gap.

17. The process according to claim 16 wherein said draining structure include a first side plate and a second side plate of said cover structure, and said at least one draining port includes at least one first draining port in said first side plate and at least one second draining port in said second side plate, wherein said first side plate and said second side plate have first and second slant surfaces for guiding the fluid which is splashed into said water-repellent chamber to be discharged out through said at least one first draining port and said at least one second draining port.

18. The process according to claim 16 wherein said at least one first air port is disposed in a side plate of said housing, and the heat generated from said electronic device is dissipated away said electronic device through said at least one first air port.

19. The process according to claim 15 wherein said housing includes an indentation portion and plural protrusion rings at a lateral side thereof, said protrusion rings being protruded from said lateral side of said housing and confined within said indentation portion.
