In this embodiment, a pair of second engaging portions 25 protrude outward from the root of the water delivery rod core 23 . The second engaging portion 25 is composed of two hollow polygonal tube walls, thereby providing some elasticity to elastically abut against the first engaging portion 115 .

The base 11 of the mounting base 1 is provided with an assembly hole 110 , and the assembly hole 110 communicates with the interior of the base 11 . Wherein the water delivery rod core 23 of the filter core 2 is provided with a plurality of water inlets and outlets 231, 232, the assembly hole 110 is connected with the water delivery pipe fitting 12 of the mounting seat 1, and the water delivery pipe fitting 12 can be connected with the water inlet and outlet ports of the filter core 2 231 and 232 are connected.

As shown in Figure 4 and Figure 6, when the mounting seat 1 and the filter core 2 are to be assembled, the first engaging part 115 and the second engaging part 25 can be located at staggered positions (as shown in Figure 6), and the filter After inserting one end of the core 2 into the mounting seat 1, and then rotating the mounting seat 1 and the filter core 2 at a predetermined angle, the first engaging part 115 and the second engaging part 25 can be engaged with each other (as shown in Figure 9 ), so that the filter core 2 can be detachably assembled on the mounting base 1.

As shown in FIG. 1 , the filter element set for water purification of the present invention can provide the function of anti-counterfeit identification, and the top wall 22 of the filter element housing 21 has at least one anti-counterfeit concave hole 222 . The shape of the anti-counterfeit protrusion 134 corresponds to the shape of the anti-counterfeit concave hole 222 . At least one anti-counterfeiting protrusion 134 is correspondingly inserted into the at least one anti-counterfeiting concave hole 222 . In this embodiment, the number of the anti-counterfeit protrusions 134 and the anti-counterfeit concave holes 222 is a pair. When a user installs a wrong filter element, the anti-counterfeit protrusion 134 cannot be fitted and the installation cannot be completed, thereby preventing the user from replacing a wrong or inappropriate filter element.

As shown in FIG. 2 to FIG. 3 , the anti-counterfeit protrusion 134 is matched with at least one guiding groove 113 formed on the assembly board 111 of the base 11 . The quantity of guide groove 113 can cooperate with anti-counterfeiting protrusion 134 The present embodiment has a pair of guide grooves 113 located between the inner ring wall 114 and the outer ring wall 112 . The anti-counterfeiting protrusions 134 of the rotating inner liner 13 correspondingly pass through the guide groove 113 to protrude from the bottom surface of the base 11 . 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 element housing 21 also has a limiting groove 226 . When one end of the filter element 2 is correctly plugged into the mounting seat 1 , the limiting protrusion 116 is located in the limiting groove 226 . When the filter core 2 rotates relative to the mounting base 1 , the limiting groove 226 is displaced relative to the limiting protrusion 116 , thereby providing guidance and limiting functions. In other words, as shown in FIG. 5 , when one end of the filter element 2 is correctly plugged into the mounting base 1 , the limiting projection 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 base 1 , the limiting protrusion 116 is located at the other end of the limiting groove 226 , and the filter element 2 cannot rotate any more. Specifically, the limiting groove 226 is arc-shaped at 90 degrees.

As shown in FIG. 4 to FIG. 7 , the filter element 2 of the present invention is plugged into the mounting seat 1 and is not locked. When the filter core 2 is assembled on the mounting base 1 , the water delivery rod core 23 of the filter core 2 can be inserted into the assembly hole 110 of the mounting base 1 . By rotating the filter element 2, along the locking direction L in Fig. 4, the second engaging portion 25 of the filter element 2 and the first engaging portion 115 of the mounting base 1 can engage with each other (see Fig. 10), so that the filter element 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 inner liner 13 and the water inlet and outlet pipes 122 of the water delivery pipe 12 are staggered. Wherein the water inlet and outlet holes 131 of the rotating lining 13 are also staggered with the water inlet and outlet pipes 121 of the water delivery pipe 12 (figure omitted). The water passing through the water delivery pipe 12 is blocked by the rotating inner liner 13 and cannot circulate temporarily.

In the filter cartridge set for water purification provided by the present invention, by inserting the anti-counterfeit protrusion 134 into the at least one anti-counterfeit concave hole 222 correspondingly, not only the anti-counterfeit function can be provided, but also the filter core can be replaced by driving the rotating inner liner 13 2 The function of automatic water stop and water intake during the process.

As shown in FIGS. 8 to 10 , the filter element 2 of the present invention is in a locked state after being rotated relative to the mounting base 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 liner 13 can rotate relative to the water delivery pipe 12 . At this time, the water inlet and outlet holes 132 of the rotating inner liner 13 are docked with the The water inlet and outlet pipe 122 of the water pipe fitting 12, wherein the inlet and outlet water hole 131 of the rotating lining 13 is also connected with the inlet and outlet water pipe 121 of the water delivery pipe fitting 12 (figure omitted), and rotates from the water-stop state (refer to Fig. 5 to Fig. 7) to communicate state (see Figures 8 to 10).

The filter element set for water purification of the present invention can not only provide an anti-counterfeiting function through the above-mentioned structural arrangement, but also drive the rotating inner liner 13 inside the mounting base 1 at the same time. During the process of installing the filter element 2, the rotating inner liner 13 can block the water inlet and outlet pipes 121, 122 of the water delivery pipe 12 to provide a water stop function. After the filter core 2 is installed, the inner liner 13 is rotated to communicate the filter core 2 with the water delivery pipe 12 .

When the filter element 2 is to be replaced, the filter element 2 can be rotated along the unlocking direction U in FIG. 1 or FIG. The process does not require turning off the water source.
