The invention discloses an air vent which is provided with an air vent shell. The vent housing defines a mounting structure, a first opening between a first end and a second end of the vent housing, a first airflow passage from the first opening, a second airflow passage from the second opening, and a discharge passage from the first airflow passage through the first end of the vent housing. The first airflow passage has a first section and a second section extending in opposite axial directions. The inlet pressure relief valve and the outlet pressure relief valve are arranged in parallel between the first airflow passage and the second airflow passage. The inlet pressure relief valve opens when a first threshold pressure differential of the second airflow passage relative to the first airflow passage is exceeded. The outlet pressure relief valve opens beyond a second pressure differential of the first airflow passage relative to the second airflow passage. A filter assembly is disposed in the vent housing across the second airflow passage.
披露了一种通气口,该通气口具有通气口壳体,该通气口壳体限定了:安装结构、在通气口壳体的第一端与第二端之间的第一开口、从第一开口起的第一气流通路、从第二开口起的第二气流通路、以及从第一气流通路穿过通气口壳体的第一端的排放通路。第一气流通路具有在相反的轴向方向上延伸的第一段和第二段。入口减压阀和出口减压阀在第一气流通路与第二气流通路之间并联布置。入口减压阀在超过第二气流通路相对于第一气流通路的第一阈值压差时打开。出口减压阀在超过第一气流通路相对于第二气流通路的第二压差时打开。过滤器组件跨越第二气流通路设置在通气口壳体中。
