Air compression device and air suction device

The invention relates to an air compression device and an air suction device. An air compression device (1) according to the present invention is provided with a compressor (10), a housing (12), a main intake port filter (16), and an opening/closing mechanism unit (21). The compressor (10) compresses the sucked air and discharges the compressed air. The housing (12) internally accommodates the compressor (10), and has a main air suction port (15) and an auxiliary air suction port (20) for introducing air sucked in by the compressor (10). The main intake port filter (16) filters air introduced into the main intake port (15). When the pressure difference between the inside and outside of the housing (12) is equal to or greater than a predetermined value, the opening/closing mechanism (21) opens the auxiliary air suction port (20) and causes air outside the housing (12) to flow into the housing (12). 本发明涉及空气压缩装置和空气抽吸装置。本发明的一样态的空气压缩装置(1)包括压缩机(10)、外壳(12)、主吸气口过滤器(16)以及开闭机构部(21)。压缩机(10)将吸入的空气压缩并喷出。外壳(12)在内部容纳压缩机(10)
