secondly, when the hook 41 of the self-locking lever 4 slides to the joint of the up-track groove leading end 612 and the in-track groove leading end 621, because the in-track groove leading end 621 is lower than the up-track groove leading end 612, the self-locking lever 4 is pressed by the elastic restoring member 5, as shown in fig. 12, the hook 41 of the self-locking lever 4 falls to the in-track groove leading end 621, and because the up-track groove leading end 612 and the in-track groove leading end 621 are intersected reversely, the movement track of the hook 41 of the self-locking lever 4 is reversed at the joint of the up-track groove leading end 612 and the in-track groove leading end 621, that is, the joint of the up-track groove leading end 612 and the in-track groove leading end 621 is the maximum stroke point of the connector 3 inserted into the inner cavity 11 of the base 1, the base water inlet 15 is butted with the filter core water inlet 31, the base 16 is butted with the water outlet 32, the filter core 8 is opened under the compression of the elastic pushing force member 7, the filter element 2 is communicated with a corresponding waterway of the base 1 and enters a filtering and purifying state; then the filter element 2 is released from being pressed, meanwhile, the compressed thrust elastic part 7 in the inner cavity 11 provides a reverse thrust for the joint 3, the joint 3 is pushed to move towards the direction of the inner cavity 11 separated from the base 1, and then the clamping hook 41 of the self-locking rod 4 cannot return to the upper rail groove 61 due to the blocking of the locking non-return step 66 at the joint of the rail groove inlet 621 and the upper rail groove outlet 612, and only can slide towards the rail groove inlet 622 along the rail groove inlet 621;
secondly, when the hook 41 of the self-locking lever 4 slides to the junction of the rail locking groove leading-out end 622 and the rail unlocking groove leading-in end 641, because the rail locking groove 63 is lower than the rail locking groove leading-out end 622, the self-locking lever 4 is elastically extruded by the reset elastic member 5, as shown in fig. 13, the hook 41 of the self-locking lever 4 falls into the rail locking groove 63, and because the compressed thrust elastic member 7 provides thrust for the joint 3, the hook 41 of the self-locking lever 4 is clamped at the locking position at the bottom of the rail locking groove 63 to tighten and fix the joint 3, thereby self-locking the joint 3 in the inner cavity 11 of the base 1;
when the filter cartridge 2 needs to be unlocked for replacement, the connector 3 of the filter cartridge 2 is moved inwards again in the interior 11 of the base 1, during which inward movement,
firstly, the joint 3 can extrude the thrust elastic piece 7 again, the thrust elastic piece 7 is compressed again, and the clamping hook 41 of the self-locking rod 4 exits from the locking position at the bottom of the locking rail groove 63; since the unlocking rail groove leading end 641 and the locking rail groove leading end 622 are intersected in the opposite direction, that is, the unlocking rail groove 64 and the locking rail groove 62 are intersected in a V shape, the locking rail groove 63 is lower than the locking rail groove leading end 622, the hook 41 of the self-locking lever 4 is blocked by the locking step 67 at the intersection of the locking rail groove 63 and the locking rail groove leading end 622, the hook 41 cannot return to the locking rail groove 62, and can only move from the locking rail groove 63 to the unlocking rail groove leading end 641 as shown in fig. 14;
secondly, the guide end 641 of the unlocking rail groove is lower than the locking rail groove 63, the hook 41 of the self-locking lever 4 falls into the unlocking rail groove 64 under the elastic extrusion of the reset elastic piece 5, the hook 41 of the self-locking lever 4 is blocked by the unlocking step 68 at the joint of the locking rail groove 63 and the guide end 641 of the unlocking rail groove, the hook 41 can return to the locking rail groove 63, and only can move from the guide end 641 of the unlocking rail groove to the guide end 642 of the unlocking rail groove;
finally, when the hook 41 of the self-locking lever 4 slides to the intersection between the unlocking rail groove lead-out end 642 and the descending rail groove lead-in end 651, since the descending rail groove lead-in end 651 and the unlocking rail groove lead-out end 642 are reversely intersected, the motion track of the hook 41 of the self-locking lever 4 is reversed at the intersection between the descending rail groove lead-in end 651 and the unlocking rail groove lead-out end 642, that is, the intersection between the descending rail groove lead-in end 651 and the unlocking rail groove lead-out end 642 is the maximum stroke point of the connector 3 unlocking and withdrawing from the inner cavity 11 of the base 1, at this time, the filter element 2 is released from being pressed, and at the same time, the compression thrust elastic member 7 in the inner cavity 11 gives a reverse thrust to the connector 3, pushing the connector 3 to move in the direction of the inner cavity 11 departing from the base 1, and since the descending rail groove lead-in end 651 and the unlocking rail groove lead-out end 642 are smoothly intersected, as shown in fig. 15, the hook 41 of the self-locking lever 4 smoothly slides to the descending rail groove lead-out end 642, and then slides to the downstream rail groove leading-out end 652 along the downstream rail groove leading-in end 651 until finally coming out of the rail outlet 653 of the downstream rail groove leading-out end 652, and returns to the original position same as that before self-locking, as shown in fig. 16, thereby completing the unlocking action. At the moment, the filter element water inlet 31 is disconnected with the base water inlet 15, the filter element water outlet 32 is disconnected with the base water outlet 16, the thrust elastic piece 7 rebounds, the one-way valve 8 is closed, the water path corresponding to the filter element 2 and the base 1 is disconnected, and the filter element 2 is taken out to smoothly complete replacement work.
In order to prevent the self-locking rod 4 from being biased, one end of the reset elastic piece 5 connected with the self-locking rod 4 forms a circular ring 51, and the circular ring 51 is used for the self-locking rod 4 to vertically penetrate through, so that the self-locking rod 4 can conveniently return to the original position when being reset.
