Cap-type vent

Abstract

Provided is a cap-type vent having a porous waterproof air-permeable sheet inserted and mounted in a cap housing having fixing ribs formed therein, and fixing the waterproof air-permeable sheet by a supporting member made from an elastic material. The provided cap-type vent comprises: the supporting member of which one end is coupled to an object to be applied; the waterproof air-permeable sheet positioned at the other end of the supporting member; and the cap housing formed in a cup shape having an opening formed at one end thereof, into which the supporting member and the waterproof air-permeable sheet are inserted through the opening, wherein the supporting member has an air circulation hole formed by penetrating the supporting member, and the fixing ribs coming in contact with the outer lateral wall of the supporting member so as to fix the supporting member and formed on the inner lateral surface of the cap housing.

Description

technical field [0001] The present disclosure relates to a cover-type ventilator, and more particularly to a cover-type ventilator that can be mounted on a headlamp, an Electric Control Unit (ECU), etc., which are mounted on a vehicle middle. Background technique [0002] Generally, a headlamp for a vehicle has a form in which a lens is mounted on the front surface of the housing, a reflector is mounted on the inner rear of the housing, and a bulb is mounted at the inner center of the reflector on the rear. [0003] When the headlights of the vehicle are operated, the internal air around the headlights is heated due to the temperature increase due to the heat generated by the bulbs. However, since the temperature of the outer surface of the lens is relatively low, moisture condenses on the inner surface of the lens to generate moisture. [0004] Conventionally, in order to solve the problem of moisture generation on the inner surface of the lens, ventilation holes are for...

AI Technical Summary

Problems solved by technology

[0005] Conventional headlamps of vehicles have a problem in that foreign matter, moisture, etc. generated during travel through the vent holes flow in to contaminate the interior

At this time, there is a problem with the headlights of the vehicle that, in case of interior contamination, the bulb fails and the brightness decreases

[0008] However, the conventional cover type ventilator has a problem in that, since the ventilation member 20 is formed in a cup shape, it is difficult to simplify the assembly process because the ventilation member 20 needs to be installed to conform to the direction of the ventilation member when coupled to the housing 10.

[0009] In addition, the conventional cover type ventilator has a problem in that, since the ventilation member 20 is formed in a cup shape, the ventilation performance is lowered due to a change in material and a change in shape under high temperature and high humidity conditions.
