It should be noted that the filter cartridges located on both sides of the filter cartridge group 5 are inserted into the support plate 1 first and the butt joint communication ports are directed to the middle filter cartridge, the positioning of the two filter cartridges is completed, then the middle filter cartridge is inserted into the support plate 1, and the ring frame 102 vertically slidably arranged on the support plate 1 is in contact with the ring frame 102, the ring frame 102 moves synchronously with the rising of the filter cartridge, that is, the ring frame 102 is linked to the force receiving frame 605 for subsequent linkage, when the filter cartridge rises to the end of the stroke, the second water pipe 603 is connected to the filter cartridges in the filter cartridge group 5.

[0045] In another embodiment of the application, the first water pipe 601 is movably connected to the second water pipe 603 by an elastic reset member, the elastic force direction of the elastic reset member is the connection direction of the second water pipe 603 and the filter cartridge group 5, further, preferably, the elastic reset member is a second spring 602, a circular ring is arranged on the outer wall of the first water pipe 601 and the second water pipe 603, the second spring 602 is arranged between the circular rings of the two water pipes, and the elastic force direction of the second spring 602 is the connection direction of the second water pipe 603 and the filter cartridges in the filter cartridge group 5, that is, when the first water pipe 601 moves outward on the receiving pipe 6, it synchronously moves the second water pipe 603 through the second spring 602.

[0046] In still another embodiment of the present application, a third spring 606 is arranged between every two force receiving frames 605, and when the force receiving frame 605 is no longer abutted by the ring frame 102, the third spring 606 is used to make every two force receiving frames 605 move towards each other. The ring frame 102 is provided with an abutting rod 103, and when the ring frame 102 moves upwards, the abutting rod 103 is wedged with the force receiving frame 605, so that the first water pipe 601 moves outwards relative to the receiving pipe 6. Further, the ring frame 102 is wedged with the force receiving frame 605 on the first water pipe 601 during the upward movement, so that the force receiving frame 605 moves away from each other. In order to reset the force receiving frame 605 when it is not under force, the third spring 606 is arranged between every two force receiving frames 605, i.e. when the two force receiving frames 605 are wedged with the abutting rod 103, they are in a state of moving away from each other, and in this state, the third spring 606 is stretched synchronously. When the force receiving frame 605 is no longer under force, it can be reset by sliding under the elastic force of the third spring 606.

[0047] In still another embodiment of the present application, the support plate 1 is provided with a guide frame 7 on the moving stroke of the second water pipe 603, and the guide frame 7 is provided with an energy storage reset mechanism which is arranged to slide. The sliding direction of the energy storage reset mechanism is perpendicular to the moving direction of the second water pipe 603. The energy storage reset mechanism comprises a moving block 701, a second connecting rod 702, a fourth spring 703 and a limiting block 704. The moving block 701 is arranged to slide on the guide frame 7, and the sliding direction of the moving block 701 is perpendicular to the moving direction of the second water pipe 603. One end of the second connecting rod 702 is connected with the moving block 701, and the other end is connected with the first water pipe 601. When the first water pipe 601 moves, the connecting rod 702 is connected to synchronously make the moving block 701 move upwards in the moving direction of the second water pipe 603. A guide slot is formed in the moving block 701, and the limiting block 704 is arranged to slide in the guide slot. The fourth spring 703 is arranged between the guide slot and the limiting block 704. The limiting block 704 is abutted with the second water pipe 603. Further, the fourth spring 703 is used to make the limiting block 704 slide inwards on the moving block 701 during the downward movement of the moving block 701, so that the fourth spring 703 is synchronously contracted, as shown in FIG. 6B. Figures 8-10As shown in the state, in the moving stroke of the first water pipe 601, the moving block 701 is vertically linked to the second water pipe 603 through the connecting rod 702 to be synchronously lifted, and in the process of the lifting, the outer wall plane of the limiting block 704 on the moving block 701 is in contact with the outer wall ring plane of the second water pipe 603, that is, the limiting block 704 plays a limiting role on the second water pipe 603, and with the gradual displacement of the first water pipe 601, the limited second water pipe 603 moves to the inside of the first water pipe 601, and the second spring 602 between the first water pipe 601 and the second water pipe 603 is also synchronously compressed, when the displacement of the first water pipe 601 makes the limiting block 704 on the moving block 701 separate from the ring of the second water pipe 603, as shown in the state, Figures 6-7 As shown in the state, at the moment when the limiting block 704 separates from the ring, the second water pipe 603 is no longer limited, at this time, the second water pipe 603 and the filter element on the filter element group 5 are connected through the elastic force of the second spring 602, the spring is compressed during the connection of the second water pipe 603, and the second water pipe 603 is connected to the communication port of the filter element in the filter element group 5 through the process of providing an instantaneous impact of the second water pipe 603, so as to facilitate the connection, and the stability after the connection is improved.

[0048] In another embodiment of the present application, a slope part 604 is formed on the second water pipe 603, and a protruding part is formed on the moving block 701, and the protruding part is wedge-shaped matched with the slope part 604, and further, Figure 13 And Figure 14 For reference, wherein Figure 13 is the initial state of the second water pipe 603 and the moving block 701, that is, the protruding part on the moving block 701 is located below the slope part 604, when the second water pipe 603 is synchronously driven by the first water pipe 601, the position does not change due to the limitation of the limiting block 704, and the position of the moving block 701 changes correspondingly due to the driving of the first water pipe 601, that is, the moving block 701 is synchronously lifted, when the limiting block 704 no longer limits the second water pipe 603 in the process of the lifting of the moving block 701, at this time, the position of the second water pipe 603 changes under the driving of the second spring 602, as shown in the state, Figure 14As shown in the state, the position of the moving block 701 rising has caused the limiting block 704 to be separated from the second water pipe 603, and at the moment of separation, the second water pipe 603 completes an impact process driven by the elastic force of the second spring 602, that is, the second water pipe 603 completes the butt joint to the filter element, and the position of the inclined surface part 604 on the second water pipe 603 and the protruding part of the moving block 701 in contact is located upwards. It needs to be explained that, due to the butt joint of the second water pipe 603 to the filter element by the spring, in some embodiments, the first water pipe 601 gradually stretches by the second spring 602 in the moving process, and in this process, the second water pipe 603 in the communication port of the filter element is directly taken out, and in other embodiments, the second spring 602 gradually stretches in the moving process of the first water pipe 601, and in this process, the second water pipe 603 in the communication port of the filter element is not taken out, so that when the second water pipe 603 is disassembled from the filter element, the protruding part of the moving block 701 is still in contact with the inclined surface part 604 and is located in the upper position of the inclined surface part 604, so that when the first water pipe 601 is displaced and reset in the receiving pipe 6, it is lowered by the synchronous linkage of the moving block 701 through the second connecting rod 702, and in the process of the moving block 701 descending, the protruding part is wedge-shaped matched with the inclined surface part 604 on the second water pipe 603, so that under the abutment of the moving block 701, the second water pipe 603 in the communication port of the filter element can be gradually moved outward and finally taken out. The protruding part on the moving block 701 assists the second water pipe 603 to complete the disassembly from the filter element.

[0049] In another embodiment provided by the application, preferably, the support plate 1 is provided with an ultrafiltration membrane filter element 2, a rear active carbon filter element 3 and a booster pump 4, which are prior art and are not described herein.

Further, as shown in Figure 15 For reference, the ring frame 102 is provided with a cross rod 105, one end of the cross rod 105 is relatively hingedly provided with a first connecting rod 608, and the first connecting rod 608 is used for being connected with the linkage frame 607 on the outer wall of the first water pipe 601, as shown in Figure 16As shown in the state, the ring frame 102 and the guide base 101 are provided with a first spring 106 for resetting the ring frame 102, when the ring frame 102 is forced to move upward by the filter core abutting, it synchronously drives two linkage frames 607 to move in opposite directions through the first connecting rod 608 on the cross rod 105, that is, it makes two first water pipes 601 move synchronously, it is to be explained that, as shown in the state, Figure 17 As shown in the state, before the water pipe automatic docking process of the filter core group 5, the first water pipe 601 is in the state of being connected to the linkage frame 607, and the second water pipe 603 is in the state of being connected to the second linkage frame 607, and the third water pipe 602 is in the state of being connected to the third linkage frame 607, and the fourth water pipe 604 is in the state of being connected to the fourth linkage frame 607, and the fifth water pipe 605 is in the state of being connected to the fifth linkage frame 607, and the sixth water pipe 606 is in the state of being connected to the sixth linkage frame 607, and the filter core group 5 is in the state of being connected to the guide base 101. Figure 18 As shown in the state, during the rising process of the ring frame 102, the limiting block 701 on the moving block 701 is about to be separated from the second water pipe 603. Figure 19 As shown in the state, the rising position of the ring frame 102 has made the limiting block 701 separated from the second water pipe 603, so that the second water pipe 603 is docked with the filter core, and the middle filter core has also completed the clamping installation with the support plate 1, when it is needed to disassemble the filter core on the support plate 1, as shown in the state, Figure 20 As shown in the state, by continuing to rise the cross rod 105, it starts to link the linkage frames 607 to move in opposite directions through the first connecting rod 608, which is the disassembly process of the second water pipe 603, as shown in the state, Figure 21 As shown in the state, when the ring frame 102 rises to the end of the stroke, the linkage frames 607 have been linked by the first connecting rod 608, so that the first water pipe 601 completes the separation of the second water pipe 603 from the filter core. Figure 22 As shown in the state, after the second water pipe 603 is separated from the filter core, the filter core clamped on the support plate 1 can be completely removed, and the ring frame 102 is no longer subjected to the force, and it slides down on the guide base 101 to complete the reset under the elastic force between the ring frame 102 and the guide base 101.
