[0021] The hydrogen production machine module 100 comprises a filtering air inlet assembly 110, a cleaning assembly 120 and a water washing assembly 130. The filtering air inlet assembly 110 is in the form of a channel penetrating through the surface of the machine body 200. Specifically, the filtering air inlet assembly 110 comprises an air inlet channel 111, a rotating frame 114, a partition plate 112, a through slot 113 and an air pump assembly 140. The air inlet channel 111 is arranged penetrating through the surface of the machine body 200. The rotating frame 114 is fixed to the inside of the air inlet channel 111 through a bearing seat.
