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.
