[0025] The technical solution of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] As Figure 1 shown, the handle plug-in type filter element assembly of the present utility model includes a filter element 3 with a plurality of L-shaped water pipe joints 10 connected to its end to correspond to different water path functions, a filter element seat 1 cooperating with the filter element 3 and communicating with a water pipe or a water path plate, and connection through holes are provided through the filter element seat 1 corresponding to the plurality of L-shaped water pipe joints 10. The filter element 3 and the filter element seat 1 are connected in a plug-in manner through the L-shaped water pipe joints 10 and the connection through holes, so as to adapt to the installation of water purifiers in more occasions and improve the convenience and application range of use.

[0027] Handles 2 are rotatably connected to both sides of the filter element 3, and the handles 2 are located between the filter element 3 and the filter element seat 1, so as to facilitate the handling of the filter element 3 when it is installed or disassembled. The locking or unlocking of the filter element 3 and the filter element seat 1 is realized through a locking component located between the two, and the function of the locking component is also assisted by the handle 2, that is, the rotation of the handle 2 drives the locking component to lock or unlock between the filter element 3 and the filter element seat 1.

[0028] Specifically, the locking device includes a coaxial cylinder formed by splicing two semi-cylinders 4, and the end surface formed by splicing the two becomes a torque receiving end surface. The coaxial cylinder is arranged at the connection of both sides of the filter element 3 and the filter element seat 1. One of the semi-cylinders 4 of the coaxial cylinder is rotatably arranged on the filter element seat 1 through a connecting shaft 7, as Figure 2 and Figure 3 shown. Correspondingly, a through hole is provided on the filter element seat 1 at the connection of the semi-cylinder 4, and the connecting shaft 7 passes through the through hole and is connected to the semi-cylinder 4. A snap ring 8 is also provided between the outer side wall of the filter element seat 1 and the end of the connecting shaft 7 on the connecting shaft 4 to limit the horizontal movement of the semi-cylinder 4. A semi-circular groove 5 matching with the semi-cylinder 4 is provided on the filter element seat 1 at the placement position of the semi-cylinder 4, so as to realize that the semi-cylinder 4 connected to the filter element seat 1 can rotate in its space.

[0029] The other semi-cylinder 4 of the coaxial cylinder is fixedly connected to the handle 2 of the filter element 3, as Figure 4 and Figure 5 shown. The semi-cylinder 4 and the handle 2 are rotatably arranged on the filter element 3 through connecting bolts 8, so as to realize the rotation of the handle 2 driving the rotation of the semi-cylinder 4 fixedly connected thereto, and further driving the rotation of the semi-cylinder 4 on the filter element seat 1 that is arranged in a combined manner with the semi-cylinder 4, so as to lock or unlock the filter element seat 1 and the filter element 3. Correspondingly, a semi-cylinder groove 5 for accommodating the semi-cylinder 4 is also provided on the filter element 3, so as to realize its rotation within its space, and the side end surface of the handle 2 is attached to the side end surface of the semi-cylinder groove 5.

[0030] A groove 6 for accommodating the handle 2 and the semi-cylinder 4 on the filter element 3 is provided on the filter element seat 1, and the semi-cylinder groove 5 for accommodating its semi-cylinder 4 on the filter element seat 1 is extended along the depth direction of the filter element seat 1 from the groove 6. The depth of the groove 6 is greater than or equal to the bottom surface radius of the semi-cylinder 4, so that when the handle 2 and the semi-cylinder 4 connected to the handle 2 rotate to the horizontal position, the filter element seat 1 can support the handle 2 and the filter element 3 at the bottom. The end surface of the handle 2 and the side end surface of the semi-cylinder 4 are located in the same plane, and when the handle 2 is in the vertical state, its end surface is attached to the end surface of the groove 6. This setting can not only unlock the filter element 3 and the filter element seat 1 when the handle 2 is in the vertical state, but also limit the vertical angle of the handle 2 by means of the groove 6, that is, limit one of its rotation limit positions. A recessed part for limiting the horizontal position of the handle 2 is provided on the filter element 3, that is, the other rotation limit position of the handle 2 is limited by the recessed part provided on the filter element 3.

[0031] The locking or unlocking state of the filter element 3 and the filter element seat 1 of the present utility model is determined by the position of the end surface formed by the combination of the two semi-cylinders 4 and the position of the semi-cylinder groove 5. That is, when the end surface formed by the combination of the two is located in the same vertical plane as the side end surface of the semi-cylinder groove 5, that is, the end surface formed by the combination of the two semi-cylinders 4 is in the vertical state, the filter element 3 and the filter element seat 1 are in the unlocked state, as Figure 6 shown. When there is a certain angle between the end surface formed by the combination of the two semi-cylinders 4 and the end surface of the semi-cylinder groove 5, that is, the end surface formed by the combination of the two semi-cylinders 4 is in the inclined state, the filter element 3 and the filter element seat 1 are in the locked state, as Figure 7 shown.
