DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3A filter with an easy-to-disassemble filter element comprises a filter housing 1, and both side outer walls of the filter housing 1 are fixed with fixing blocks 7 by bolts. A fastening groove 8 is provided at the bottom end of the fixing block 7, and a fastening rod 9 is clamped between the two fastening grooves 8. A threaded rod 10 is threadedly inserted into the bottom of the fastening rod 9, and a pressure cover 11 is sleeved at the bottom end of the filter housing 1. A second mounting block 13 is integrally formed on the inner wall of the pressure cover 11, and a filter element 15 is inserted on the top of the second mounting block 13. Unscrew the threaded rod 10, and then remove the fastening rod 9 from the fastening groove 8. Then, unscrew the pressure cover 11 to remove the filter element 15.
