The guide groove 113 can limit the rotation angle of the rotating lining 13 .

As shown in FIG. 1 , FIG. 5 , and FIG. 8 , the top wall 22 of the filter housing 21 also has a limiting groove 226 . When one end of the filter element 2 is correctly inserted into the mounting seat 1 , the limiting protrusion 116 is located in the limiting groove 226 . When the filter element 2 rotates relative to the mounting seat 1 , the limiting groove 226 is displaced relative to the limiting protrusion 116 , thereby providing guiding and limiting functions. In other words, as shown in FIG. 5 , when one end of the filter element 2 is correctly inserted into the mounting seat 1 , the limiting protrusion 116 is located at one end of the limiting groove 226 . As shown in FIG. 8 , after the filter element 2 is installed relative to the mounting seat 1 , the limiting protrusion 116 is located at the other end of the limiting groove 226 , and the filter element 2 cannot be rotated any more. Specifically, the limiting groove 226 is in an arc shape of 90 degrees.

As shown in FIG. 4 to FIG. 7 , the filter element 2 of the present invention is inserted into the mounting seat 1 in an unlocked state. When the filter element 2 is assembled to the installation seat 1 , the water delivery rod core 23 of the filter element 2 can be inserted into the assembly hole 110 of the installation seat 1 . By rotating the filter core 2, along the locking direction L in FIG. 4 , the second engaging portion 25 of the filter core 2 and the first engaging portion 115 of the mounting seat 1 can be engaged with each other (see FIG. 10 ), so that the filter core 2 can be detachably assembled on the mounting base 1. As shown in FIG. 7 , at this time, the water inlet and outlet holes 132 of the rotating lining 13 and the water inlet and outlet pipes 122 of the water delivery pipe member 12 are staggered. The water inlet and outlet holes 131 of the rotating inner lining 13 are also staggered with the water inlet and outlet pipes 121 of the water delivery pipe member 12 (not shown). The water passing through the water delivery pipe 12 is blocked by the rotating lining 13 and cannot flow temporarily.

In the filter core set for water purification provided by the present invention, by inserting the anti-counterfeiting convex member 134 into the at least one anti-counterfeiting concave hole 222 correspondingly, it can not only provide anti-counterfeiting function, but also can replace the filter core by driving the rotating inner lining 13 2. The function of automatic water stop and water entry during the process.

As shown in FIG. 8 to FIG. 10 , the filter element 2 of the present invention is in a locked state after being rotated relative to the mounting seat 1 . When the filter core 2 is rotated, at least one anti-counterfeiting protrusion 134 can be driven by the filter core 2 , so that the rotating inner lining 13 can rotate relative to the water delivery pipe member 12 . At this time, the water inlet and outlet holes 132 of the rotating lining 13 are connected to the water inlet and outlet pipes 122 of the water conveying pipe fitting 12, wherein the water inlet and outlet holes 131 of the rotating inner lining 13 are also connected to the water inlet and outlet pipes 121 of the water conveying pipe fitting 12 (figure omitted), Rotate from the water-stop state (refer to Figures 5 to 7) to the connected state (refer to Figures 8 to 10).

Through the above-mentioned structural arrangement, the filter core group for water purification of the present invention can not only provide the function of anti-counterfeiting, but also drive the rotating lining 13 inside the mounting base 1 at the same time. During the process of installing the filter core 2, the rotating inner lining 13 can block the water inlet and outlet pipes 121 and 122 of the water delivery pipe member 12 to provide a water stop function. After the installation of the filter core 2 is completed, the inner lining 13 is rotated to connect the filter core 2 to the water delivery pipe 12 .

When the filter core 2 is to be replaced, rotate the filter core 2 along the unlocking direction U in Figure 1 or Figure 4, and then the filter core 2 can be taken out from the mounting seat 1 downward. The process does not require turning off the water supply.

[Advantageous effects of the embodiment]

One of the beneficial effects of the present invention is that the filter core set for water purification provided by the present invention can not only provide the anti-counterfeiting function, but also provide the anti-counterfeiting convex member 134 correspondingly inserted into the at least one anti-counterfeiting concave hole 222. Better anti-counterfeiting structure to prevent consumers from misusing filters with unknown routes. In addition, the rotating inner lining 13 can be driven by rotating the filter core 2, and the rotating inner lining 13 and the water delivery pipe 12 can be staggered or connected, thereby achieving the functions of automatic water stop and water intake during the replacement of the filter core 2.
