Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6The utility model provides a technical solution: a pneumatic solenoid valve that is easy to clean, including a pneumatic solenoid valve body 1, an auxiliary block 2, a mounting tube 3, a first sealing ring 4, a filter screen 5, a second sealing ring 6, a mounting plate 7, a threaded connecting tube 8, a mounting plate 9, a support rod 10, a limit plate 11, a fixed protrusion 12, a connecting mechanism 13, a movable plate 14, a spring 15, a connecting block 16 and a fixing pin 17.

[0031] When using this easy-to-clean pneumatic solenoid valve, Figure 1 and Figure 2 As shown, during assembly, the filter screen 5 and the second sealing ring 6 are first placed at the near port and the exhaust port on the pneumatic solenoid valve body 1 respectively, and then the mounting plate 7 drives the mounting tube 3 to be plugged into the air inlet and the exhaust port on the pneumatic solenoid valve body 1, and at the same time, the mounting tube 3 squeezes and fixes the filter screen 5, and the second sealing ring 6 is fitted between the second sealing ring 6 and the pneumatic solenoid valve body 1, and the first sealing ring 4 is sleeved on the outside of the mounting tube 3, and the first sealing ring 4 is fitted between the mounting plate 7 and the pneumatic solenoid valve body 1. Through the arrangement of the first sealing ring 4 and the second sealing ring 6, the sealing effect of the connection can be improved, and the overall air tightness is better, and through the arrangement of the filter screen 5, impurities in the gas can be filtered;

[0032] After the insertion is completed, Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the side of the mounting plate 7 is fixedly connected with a mounting plate 9, and the mounting plate 7 drives the mounting plate 9 to be placed on the side of the pneumatic solenoid valve body 1.
