[0037] The filter element 2 is fixedly installed with an end cap 4. Two sliding grooves 5 are formed on the front end surface of the end cap 4. The two sliding grooves 5 are symmetrically arranged to each other. A sliding lock 6 is slidably installed in the sliding groove 5.

[0038] An outer cover 7 is fixedly installed on the front side of the end cover 4. The left and right ends of the outer cover 7 are respectively formed with slots 8. The outer end of the sliding lock 6 is fitted into the slot 8 with clearance. A handle 9 is rotatably installed inside the outer cover 7. A toggle rod 10 is formed on the front side of the sliding lock 6. A self-locking handle 11 is fixedly installed on the handle 9.

[0039] The handle rod 9 is rotated to drive the two sliding locks 6 to extend or retract the slot 8 of the outer cover 7, the left and right sides of the front end of the filter core slot 3 are formed with lock grooves 12, and the sliding locks 6 are inserted into the lock grooves 12 in one-to-one gap cooperation when the sliding locks 6 extend out of the outer cover 7;

[0040] The principle is that: during installation, the entire end cover 4 and filter core 2 are directly lifted by the self-locking handle 11, and the tail end of the filter core 2 is aligned with the filter core slot 3 on the water purifier 1 to perform a plug-in action, after plugging in place, the self-locking handle 11 is loosened, and the self-locking handle 11 will rotate downward under its own gravity, and then drive the handle rod 9 to rotate downward, after the handle rod 9 rotates downward, the handle rod 9 will drive the two sliding locks 6 to extend out of the slot 8 of the outer cover 7, at this time, the outer end of the sliding lock 6 can be inserted into the lock groove 12 in gap cooperation, and the automatic locking of the filter core 2 in the filter core slot 3 is realized; when disassembling, rotate the self-locking handle 11 upward, at this time, the self-locking handle 11 will drive the handle rod 9 to rotate upward, the handle rod 9 will drive the two sliding locks 6 to retract into the slot 8 of the outer cover 7 through the driving piece 10, and then separate from the lock groove 12 of the filter core slot 3, so that when disassembling, only the self-locking handle 11 needs to be lifted and pulled, which is convenient and fast. Compared with the tail end of the existing technology, the self-locking handle has the advantages of convenient operation, time saving and labor saving.

[0041] Further, the outer sides of the left and right ends of the handle rod 9 are formed with screw rod driving pieces 13, the two screw rod driving pieces 13 are arranged symmetrically left and right, and the driving rod 10 is moved by the screw rod driving piece 13 when the handle rod 9 rotates; the principle of screw rod conveying is used to convert the rotating power into back and forth moving thrust, and then facilitate the self-locking and disassembling action of the end cover 4.

[0042] Further, the outer sides of the screw rod driving pieces 13 are formed with two spiral edges 14, the two spiral edges 14 are arranged apart from each other, and the front end of the driving rod 10 is gap fitted and installed between the two spiral edges 14; the two spiral edges 14 can be used to drive the driving rod 10 to move back and forth, and then realize self-locking or disassembling, which is convenient and fast.

[0043] Further, the two spiral edges 14 located at the left end of the handle rod 9 are arranged in right rotation, and the two spiral edges 14 located at the right end of the handle rod 9 are arranged in left rotation; when the self-locking handle 11 is lifted upward, the spiral edges 14 on the handle rod 9 can drive the driving rod 10 to move inward, so that the sliding lock 6 retracts into the slot 8 of the outer cover 7, and the action of quick unlocking is realized; after installation is completed, the self-locking handle 11 can drive the handle rod 9 to rotate downward under its own weight, the spiral edges 14 can drive the driving rod 10 to move outward, so that the sliding lock 6 extends out of the slot 8 of the outer cover 7 and is inserted and locked with the lock groove 12.

[0044] Further, the front side of the sliding groove 5 is formed with a limiting edge 15, which is located at the inner side of the screw rod pushing piece 13; the middle part of the front side of the limiting edge 15 is formed with a semicircular recessed groove 16, and the handle rod 9 is gap-fitted and installed in the carrying recessed groove; the accurate positioning installation of the handle rod 9 can be ensured.

[0045] Further, the front side of the sliding groove 5 is formed with a limiting edge 15, which is located at the inner side of the screw rod pushing piece 13; the middle part of the front side of the limiting edge 15 is formed with a semicircular recessed groove 16, and the handle rod 9 is gap-fitted and installed in the carrying recessed groove; the accurate positioning installation of the handle rod 9 can be ensured.

[0046] Further, the left and right sides of the outer cover 7 are formed with a cutting groove 18, one side of the cutting groove 18 is formed with a through hole 19, the self-locking handle 11 is in a semicircular arc structure, the two ends of the self-locking handle 11 are respectively gap-fitted and installed in the cutting groove 18, the inner sides of the two ends of the self-locking handle 11 are respectively rotationally fitted and installed in the through hole 19, and the two ends of the self-locking handle 11 are respectively fixedly installed at the two ends of the handle rod 9.

[0047] The rear side of the cutting groove 18 is formed with a deepening groove 20.

[0048] When the self-locking handle 11 is downward rotated to the limit position, the self-locking handle 11 abuts against the front side of the outer cover 7.

[0049] When the self-locking handle 11 is upward rotated to the limit position, the end of the self-locking handle 11 abuts in the cutting groove 18 and the deepening groove 20.

[0050] The space of the end face of the outer cover 7 can be reasonably utilized to install the self-locking handle 11, so that the occupied space of the whole is reduced.

[0051] Further, the rotatable angle of the self-locking handle 11 is 0-90°; the quick unlocking disassembly and self-locking installation can be realized, and the actual operation and use are facilitated.
