Abstract

An opening device for a urea water inlet may include a first body configured to be provided on an external side of an inlet of a urea filler neck; a second body disposed at an upper end portion of thefirst body with a ventilation gap between the first body and the second body, and provided with an internal space to be disposed above the inlet; a cover disposed at an upper end portion of the second body, and configured to receive a force to open the internal space of the second body; an opener provided in the second body, and configured to hold the cover at the upper portion of the second bodywhen the cover is configured to close the internal space, and to release holding of the cover when being pressed toward an interior of the second body; and a membrane disposed between the first bodyand the second body to pass only air therethrough while covering the ventilation gap.

Description

technical field [0001] The present invention generally relates to an opening device for a urea water inlet of a vehicle. More particularly, the present invention relates to an opening device for a urea water inlet of a vehicle, in which the inlet can be easily opened without removing a urea cap attached to the inlet of the urea nozzle from the inlet. Background technique [0002] Usually, diesel engine vehicles are applied with urea water system to purify the exhaust gas. The urea water system supplies urea water to a catalytic converter of an engine exhaust system, and the urea water supplied to the catalytic converter reacts with nitrogen oxides in exhaust gas to reduce them to nitrogen and water. [0003] The urea water system includes: a urea tank storing urea water; a urea nozzle connected to the urea tank to allow the urea water to flow to the urea tank; and a urea cap opening and closing an inlet of the urea nozzle. [0004] The traditional urea cap is applied with ...
