When the purge pipe 604 is in a normal operation state, the pressure gauge 3 maintains a normal detection pressure unchanged, and when the purge pipe 604 is clogged to lower the purge efficiency, the pressure detected by the pressure gauge 3 is increased.
When the air pressure detection meter 3 recognizes that the metal film filter 6 is significantly increased, the dirt collecting pipe 904 is opened at this time, so that the pressure value in the purifying pipe 604 is instantaneously reduced, and the pressure in the flow pipe 601 is quickly impacted on the pipe wall of the purifying pipe 604, so that the purpose of separating impurities is achieved.
The impurities separated by the purifying pipe 604 fall on the detecting plate 908 through the dirt collecting pipe 904, when the impurities pass through the dirt collecting pipe 904, the impurities firstly fall on the detecting plate 908, the weight of the impurities is identified by the detecting plate 908, meanwhile, the filtering service life of the metal film filter 6 is identified according to the weight detected by the detecting plate 908, when the air pressure component 8 detects that the pressure value in the metal film filter 6 is abnormal, the separating component 9 is utilized to clean the metal film filter 6, when the cleaned impurities fall on the detecting plate 908 through the dirt collecting pipe 904, the impurities on the detecting plate 908 are identified, when the detecting plate 908 detects the weight of the impurities is small, namely, the metal film filter 6 is still in a normal working state, when the detecting plate 908 detects the weight of the impurities is large, namely, the working state of the metal film filter 6 is reduced, and maintenance or replacement is needed in time, so that the working efficiency of the metal film filter 6 is ensured.

Step two, the pressurizing pipe 906 and the ventilation plate 905 are utilized to inflate the metal film filter 6, so that the pressure in the flow pipe 601 is driven to move into the purifying pipe 604;
Step three, when the air pressure detection meter 3 recognizes that the pressure value in the metal film filter 6 reaches a preset value, the dirt collecting pipe 904 is controlled to be opened, so that the pressure in the purifying pipe 604 is released rapidly, and the air in the flow pipe 601 is driven to move into the purifying pipe 604 rapidly;
Step four, after removing impurities of the purifying tube 604 by using air pressure, moving the impurities onto the detecting plate 908 by using the dirt collecting tube 904, and identifying the quality on the detecting plate 908 by using the elastic rod 907;
and fifthly, the liquid entering the dirt collecting pipe 904 is purified by the dirt storing box 901 and then discharged into the circulating assembly 7.
