Abstract

The invention provides a water-proof housing for an electronic equipment. The water-proof housing, according to the invention, has built-in drainage to cope with penetration of liquid into the electronic equipment. The water-proof housing essentially includes a main body with a plurality of ventilation holes formed thereon. The housing also includes a plurality of drainpipes which each corresponds to one of the ventilation holes and a collecting hopper is formed at one end thereof. The drainpipes are mounted on an inner wall of the main body such that each of the collecting hoppers is disposed underneath the corresponding ventilation hole. Once liquid flows into the interior of the electronic equipment through the ventilation holes, the liquid is collected by the collecting hoppers and drained out of the electronic equipment from an outlet.

Claims

1. A water-proof housing for an electronic equipment, comprising:

a main body configured to protect the electronic equipment;

a plurality of ventilation holes formed through and on the main body;

a plurality of drainpipes which each corresponds to one of the ventilation holes and has an exit formed at one end thereof; and

a plurality of collecting hoppers which each is formed at another end of one of the drainpipes, wherein the drainpipes are mounted on an inner wall of the main body such that each of the collecting hoppers is disposed underneath the corresponding ventilation hole;

wherein once a liquid flows into the interior of the electronic equipment through the ventilation holes, the liquid is collected by the collecting hoppers.

2. The water-proof housing of claim 1, wherein the main body has a top, and the ventilation holes are formed near the top of the main body.

3. The water-proof housing of claim 2, wherein the main body has a bottom, and the water-proof housing further comprises:

at least one outlet formed near the bottom of the main body, the exit of each drainpipe being coupled to the outlet;

wherein the liquid collected by the collecting hoppers is drained out of the main body from the outlet.

4. The water-proof housing of claim 3, wherein each of the collecting hoppers has an opening covering the corresponding ventilation hole.

5. The water-proof housing of claim 3, wherein the electronic equipment is a monitor.

6. The water-proof housing of claim 3, wherein the electronic equipment is a projector.

7. A monitor, comprising:

a housing configured to protect the monitor;

a plurality of ventilation holes formed through and on the housing;

a plurality of drainpipes which each corresponds to one of the ventilation holes and has an exit formed at one end thereof; and

a plurality of collecting hoppers which each is formed at another end of one of the drainpipes, wherein the drainpipes are mounted on an inner wall of the main body such that each of the collecting hoppers is disposed underneath the corresponding ventilation hole;

wherein once a liquid flows into the interior of the monitor through the ventilation holes, the liquid is collected by the collecting hoppers.

8. The monitor of claim 7, wherein the housing has a top, and the ventilation holes are formed near the top of the housing.

9. The monitor of claim 8, wherein the main body has a bottom, and the water-proof housing further comprises:

at least one outlet formed near the bottom of the housing, the exit of each drainpipe being coupled to the outlet;

wherein the liquid collected by the collecting hoppers is drained out of the housing from the outlet.

10. The monitor of claim 9, wherein each of the collecting hoppers has an opening covering the corresponding ventilation hole.
