[0034] Working principle: when the nitrogen generator 25 is working, the air outside will enter the tank 1 through the air inlet pipe 27 arranged on the left side wall of the tank 1. When the air enters the tank 1, the water in the air will gather on the outer wall of the baffle cylinder 13, form water droplets and drop to the bottom of the tank 1, so as to separate and filter the gas and water in the air. At the same time, the impurities in the air will also fall into the bottom of the tank 1 under the centrifugal force. At the same time, the air will be pressed into the baffle cylinder 13 from the lower part under the air inlet pressure. When the air enters the baffle cylinder 13 from the lower part, the filter plate 15 arranged at the air inlet 14 of the baffle cylinder 13 will adsorb and filter the dust and other particulate matters in the air. The air after filtering and purifying enters the baffle cylinder 13, and then enters the connecting pipe 24 through the mounting pipe 23 communicated with the top of the tank 1, and then enters the inside of the nitrogen generator 25 from the air inlet end of the nitrogen generator 25 through the connecting pipe 24, so as to achieve the purpose of filtering and purifying.

The two moving blocks 11 and the plug 12 move away from each other through the bidirectional threaded rod 9. Then the limiting of the connecting block 3 is limited, so that the top cover 2 can be opened and taken out. Then the pressing block 18 is squeezed by hand to cause the deformation and contraction of the flexible spring 17, so that the end of the flexible spring 17 is separated from the limiting of the limiting block 22. The filter plate 15 can be disassembled and replaced. When installing, the flexible spring 17 on both sides of the filter plate 15 is aligned and inserted into the slot 20 on the disassembling block 19. The outer end of the flexible spring 17 is limited by the limiting block 22, so as to realize the installation of the filter plate 15.
