PIPE SHIELD OF VENTILATION APPARATUS

WIPO Patent Application WO/2017/020727

A1

A pipe shield (30) of a ventilation apparatus (20) is disposed at an outdoor side relative to a ventilation apparatus body (24) disposed at an indoor side, and consists of a pipe shield base (31) and a rear cover (32). The pipe shield (30) is provided with an air inlet (35) and an air outlet (36) perpendicular to each other. The rear cover (32) of the pipe shield (30) is provided with a left side plate (321), a right side plate (322), and a rear side plate (323). A distance from the pipe shield base (31) to the rear side plate (323) of the rear cover (32) opposite to the air inlet (35) of the pipe shield increases along a direction towards the air outlet (36) of the pipe shield. A baffle (40) is disposed in the middle of the rear cover (32). The baffle (40) is fixed in the pipe shield (30) by means of a rotating shaft (46) fixed on the left side plate (321) and the right side plate (322). The rotating shaft (46) is provided with a spring (50) capable of enabling the baffle (40) to unfold. The pipe shield of a ventilation apparatus has the advantages of preventing wind and rain from reversely flowing into a room while reducing wind resistance and increasing blast volume, and reducing noise.
