Abstract
A pipe shield of a ventilating apparatus is disposed at an outdoor side relative to a ventilating apparatus body disposed at an indoor side, and includes a pipe shield base and a rear cover. The pipe shield has an air inlet and an air outlet disposed perpendicular to each other. The pipe shield's rear cover has a left side plate, a right side plate and a rear side plate. The distance from the pipe shield base to the rear side plate of the rear cover opposite to the air inlet of the pipe shield increases in a direction towards the air outlet of the pipe shield. A baffle is disposed at the middle portion of the rear cover, and fixed within the pipe shield by a rotating shaft fixed on the left side plate and the right side plate, the rotating shaft has a spring enabling the baffle to unfold.
