When the staff disassembles between the filter housing 1, the upper shell 101 and the lower shell 102 and needs to disassemble the filter element 5, push the two limiting holders B502 to slide in the opposite directions between the chute C501 and the inside of the limiting slots B6, squeeze the limiting block B602 to drive the damping telescopic rod B601 and the outer spring to contract, so that after the limiting holder B502 is released from the inside of the limiting slots B6, push the filter element 5 to slide out of the installation groove 4, and drive the limiting holder B502 to squeeze the limiting block B602 to slide out of the limiting groove B503. After the limiting holder B502 slides out of the limiting slots B6, the disassembly of the filter element 5 is completed.
