That is, when the slider 10 is slid in a direction approaching the locking groove 23 and stored in the locking groove 23, the stopper 34 provided on the housing body 31 abuts against the stopper projection 151, so that the slider 10 is prevented from further sliding, and the slider 10 is positioned.
Further, a filter element taking and placing opening for taking and placing the composite filter element 20 is formed in the top of the housing body 31, so that the composite filter element 20 enters the housing from the filter element taking and placing opening in the top of the housing body 31. The top of the housing body 31 may include a gland that covers the cartridge access opening to better protect the composite cartridge 20. In this embodiment, the top of the housing body 31 does not include a gland, so that the composite filter element 20 is more convenient to take and place. Further, the cartridge pick-and-place port communicates with the through-hole 33.
Referring to fig. 3, the composite filter element 20 includes a filter element body 21 and a guide rib 22 disposed on an outer wall of the filter element body 21, wherein an extending direction of the guide rib 22 is consistent with an extending direction of the filter element body 21, a clamping groove 23 is formed on the outer wall of the filter element body 21 and located above the guide rib 22, and an extension line of the guide rib 22 passes through a notch of the clamping groove 23.

When the filter element body 21 moves into the shell until the clamping part 15 is out of contact with the guide rib 22, no acting force acts on the elastic piece at this time, the elastic piece stretches, so that the clamping part 15 slides into the clamping groove 23, and the connection between the composite filter element 20 and the sliding block 10 is realized, and the composite filter element 20 and the shell are fixed. In this embodiment, the guide ribs 22 are in a nonlinear structure, the number of the guide ribs 22 is two, one ends of the two guide ribs 22, which are close to the notch, are far away from each other and are parallel to each other, and one ends of the two guide ribs 22, which are far away from the clamping groove 23, are connected. By such arrangement, the greater the depth of penetration of the cartridge body 21 into the housing, the greater the force exerted by the guide rib 22 on the engagement portion 15.
Further, a movable handle 24 is provided on the top of the cartridge body 21. The handle 24 can rotate relative to the filter element body 21, and the composite filter element 20 needing to be replaced is taken out or put in through the handle 24, so that the replacement operation of the composite filter element 20 is conveniently realized.
