[0002] The core component of a water purifier is the filter element. After a period of use, the filter element is prone to clogging, necessitating replacement to ensure water flow. Currently, most filter elements on the market are disposable, typically installed on a base using a screw-on design. As the flow rate of RO filter elements increases from 50G to 1200G, the diameter of the filter element also increases, requiring greater force to twist the element. For example, a 1000G filter element can weigh up to 4KG when filled with water, creating a difficult filter element replacement experience for users.

[0050] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0051] Reference below Figures 1-13 The filter element assembly 100 according to an embodiment of the present invention is described. The present invention also provides a water purifier having the filter element assembly 100 .

[0052] Reference Figures 1-4 As shown, the filter cartridge assembly 100 according to an embodiment of the present invention includes a waterway plate 60, a turntable assembly 10, and a filter cartridge assembly 20. The waterway plate 60 is provided with a plurality of first water inlets 66 (e.g., four in this embodiment), the turntable assembly 10 is mounted on the waterway plate 60, and the turntable assembly 10 is rotatably mounted on the waterway plate 60. The filter cartridge assembly 20 is provided with a plurality of second water inlets 21 (e.g., four in this embodiment). The plurality of first water inlets 66 and the plurality of second water inlets 21 are connected in a one-to-one correspondence, thereby forming multiple water flow channels between the waterway plate 60 and the filter cartridge assembly 20.

[0053] Among them, reference Figure 2 and Figure 4The turntable assembly 10 is rotatably mounted on the waterway plate 60. A guide post 11 is disposed on the inner side of the turntable assembly 10, and a guide rail 22 is disposed on the outer side of the filter element assembly 20. The guide post 11 fits within the guide rail 22 and moves unidirectionally within the guide rail 22. Thus, the guide rail 22 is disposed on the filter element assembly 20, and the guide post 11 is disposed on the turntable assembly 10. The filter element assembly 20 is locked by sliding the guide post 11 within the guide rail 22. Specifically, the guide post 11 can be stuck within the guide rail 22. The filter element assembly 20 is driven by external forces, the design of the guide rail 22, and the reset force (described below) on the filter element assembly 20, thereby locking and separating the filter element assembly 20.

[0054] Among them, the filter element assembly 20 has a locking position and an unlocking position, and the locking position and the unlocking position are spaced apart in the up and down directions. It should be noted here that the up and down directions can be understood as the two directions for the installation and removal of the filter element assembly 20, usually the vertical up and down directions, but in some embodiments, it can also be other directions. When the filter element assembly 20 is in the locking position, the filter element assembly 20 and the turntable assembly 10 are locked and matched to realize the flow of water. When the filter element assembly 20 is in the unlocking position, the filter element assembly 20 and the turntable assembly 10 are released from the locking state. At this time, the waterway is closed, and the user can remove the filter element assembly 20 from the turntable assembly 10 (that is, remove the waterway plate 60).

[0055] Furthermore, the turntable assembly 10 is configured to apply a reset force to the filter cartridge assembly 20 to drive the filter cartridge assembly 20 from the unlocked position to the locked position or from the locked position to the unlocked position. That is, the turntable assembly 10 can apply a reset force to the filter cartridge assembly 20, so that when the filter cartridge assembly 20 moves from the unlocked position to the locked position, the reset force can continuously push the filter cartridge assembly 20. Furthermore, when the filter cartridge assembly 20 is in the locked position, the reset force causes the guide post 11 to always lock with the guide rail 22, thereby locking the filter cartridge assembly 20 to the turntable assembly 10, thereby achieving assembly between the filter cartridge assembly 20 and the waterway plate 60. Of course, when the filter cartridge assembly 20 moves from the locked position to the unlocked position, the reset force can continuously push the filter cartridge assembly 20, causing the guide post 11 to slide along the guide rail 22 and ultimately slide out of the guide rail 22, thereby separating the filter cartridge assembly 20 from the turntable assembly 10. The specific structure of the reset force will be described in detail below.

[0056] Thus, the filter element assembly 20 and the turntable assembly 10 achieve transmission cooperation through the guide post 11 and the slide rail, so that pressing the filter element assembly 20 can cause the guide post 11 to slide in the guide rail 22, so that the guide post 11 and the guide rail 22 are locked with each other, thereby achieving a locking cooperation between the filter element assembly 20 and the turntable assembly 10. Furthermore, pressing the filter element assembly 20 again causes the guide post 11 to slide in the guide rail 22, so that the guide post 11 slides out of the guide rail 22, thereby achieving separation between the filter element assembly 20 and the turntable assembly 10.

[0057] Next, the design of the guide rail 22 will be described in detail.

[0058] Reference Figure 5 and Figure 6 As shown, the guide rail 22 protrudes outward from the filter element assembly 20 to form a groove segment (guide rail) structure. The guide rail 22 has a total of six sections of guide grooves connected front to back, namely the first groove section 221, the second groove section 222, the third groove section 223, the fourth groove section 224, the fifth groove section 225, and the sixth groove section 226.

[0059] Next, the first slot section 221, the second slot section 222, and the third slot section 223 will be described. The second slot section 222 is disposed between the first slot section 221 and the third slot section 223. The end of the third slot section 223 facing away from the second slot section 222 is in a locked position, and the end of the first slot section 221 facing away from the second slot section 222 is in an unlocked position. A locking boss 23 is also provided on the filter element assembly 20. When the filter element assembly 20 is in the locked position, the guide post 11 and the locking boss 23 lock and cooperate to lock the filter element assembly 20 and the turntable assembly 10. In other words, the guide rail 22 is provided with the first slot section 221, the second slot section 222, and the third slot section 223, and the guide rail 22 is also provided with the locking boss 23. This allows the guide post 11 to lock and cooperate with the locking boss 23 when the filter element assembly 20 is in the locked position, thereby securing the filter element assembly 20 to the turntable assembly 10. It should be noted here that, in this embodiment, the locking boss 23 is configured as a table-like structure protruding outward from the filter element assembly 20. In other embodiments, it can also be configured as a protruding wall, rib, etc., as long as the structure can perform position locking and movement guiding functions on the guide column 11.

[0060] Specifically, when the filter element assembly 20 moves from the unlocked position to the locked position, the guide post 11 first slides within the first slot section 221, then slides within the second slot section 222, and finally slides through the third slot section 223 until it locks with the locking boss 23. At this point, the filter element assembly 20 is in the locked position. The locked position is above the unlocked position, that is, the filter element assembly 20 first descends and then ascends. Due to the locking engagement between the filter element assembly 20 and the locking boss 23, the filter element assembly 20 and the turntable assembly 10 can be locked together.

[0061] Among them, reference Figure 5 and Figure 6 As shown, the locking boss 23 is provided with a locking groove 231. When the filter element assembly 20 is in the locked position, the guide post 11 is engaged in the locking groove 231. Thus, the locking boss 23 is provided with the locking groove 231. When the filter element assembly 20 is in the locked position, the guide post 11 is locked with the locking groove 231, thereby achieving locking between the guide post 11 and the guide rail 22, and further achieving locking between the filter element assembly 20 and the turntable assembly 10.

[0062] And, refer to Figure 5 and Figure 6 As shown, the second slot section 222 is tilted toward one side of the locking boss 23. This tilt allows the guide post 11 to drive the turntable assembly 10 to rotate when sliding within the second slot section 222. Furthermore, the locking boss 23 is provided with a guide bevel 232, one end of which forms a locking groove 231. The horizontal projection of the junction between the third slot section 223 and the second slot section 222 is offset from the other end of the guide bevel 232, and the junction between the third slot section 223 and the second slot section 222 is adjacent to the locking groove 231. That is, when the guide post 11 is located at the end of the second slot section 222 facing away from the first slot section 221, the horizontal projection of the guide post 11 is within the coverage of the guide bevel 232, allowing the guide post 11 to slide along the guide bevel 232 toward the locking groove 231 when sliding within the third slot section 223.

[0063] With such a configuration, the guide column 11 can enter the guide rail 22 from the first section of the first slot section 221, and then be locked with the locking groove 231 under the guidance of the second slot section 222 and the third slot section 223, thereby realizing the locking fit between the filter element assembly 20 and the turntable assembly 10.

[0064] Similarly, please continue to refer to Figure 5 and Figure 6As shown, the fourth slot section 224, the fifth slot section 225, and the sixth slot section 226 further provided on the guide rail 22 will be described. The fifth slot section 225 is provided between the fourth slot section 224 and the sixth slot section 226. The end of the sixth slot section 226 facing away from the fifth slot section 225 is in the unlocked position, and the end of the fourth slot section 224 facing away from the fifth slot section 225 is in the locked position. The fourth slot section 224 is tilted toward the side facing away from the locking boss 23. Thus, the fourth slot section 224, the fifth slot section 225, and the sixth slot section 226 are provided on the guide rail 22, so that the guide post 11 first slides within the fourth slot section 224, then within the fifth slot section 225, and finally slides out of the guide rail 22 through the sixth slot section 226. At this point, the filter element assembly 20 is in the unlocked position.

[0065] Among them, the locking position is located above the unlocking position, that is, the filter element assembly 20 first rises, and then under the guidance of the fourth groove section 224, the guide column 11 and the locking groove 231 are separated, and finally descends to the unlocking position, thereby realizing the separation between the filter element assembly 20 and the turntable assembly 10.

[0066] Further, refer to Figure 5 and Figure 6 As shown, the projection of the fourth slot segment 224 on the horizontal plane on the side facing away from the third slot segment 223 is offset from the locking groove 231 and is located close to the fifth slot segment 225. That is, the end of the fourth slot segment 224 and the locking groove 231 are offset from each other, so that the guide post 11 can be separated from the locking groove 231 by being guided by the fourth slot segment 224, thereby allowing the guide post 11 to enter the fifth slot segment 225 and then slide out of the guide rail 22 through the sixth slot segment 226. At this time, the filter element assembly 20 and the turntable assembly 10 are separated from each other.

[0067] like Figure 6 As shown, a first guide arc surface 227 is provided on the side of the first slot segment 221 away from the second slot segment 222, and a second guide arc surface 228 is provided on the side of the sixth slot segment 226 away from the fifth slot segment 225. With this arrangement, the first guide arc surface 227 and the second guide arc surface 228 are provided at the head end of the first slot segment 221 and the end end of the sixth slot segment 226, respectively. This facilitates the guide post 11 to be guided by the arc surface and thus enter the guide rail 22, improving the smoothness of the locking between the filter element assembly 20 and the turntable assembly 10, thereby facilitating the user's installation and replacement of the filter element assembly 20.

[0068] The above is a description of the main groove structure of the guide rail 22. Among them, the first groove section 221, the second groove section 222 and the third groove section 223 are from the unlocked position to the locked position, and the fourth groove section 224, the fifth groove section 225 and the sixth groove section 226 are from the locked position to the unlocked position.

[0069] Next, refer to Figure 5As shown, a raised arc surface 271 is provided on the side of the first slot segment 221 facing the second slot segment 222, a first step difference 272 is provided between the second slot segment 222 and the third slot segment 223, a second step difference 273 is provided between the fourth slot segment 224 and the third slot segment 223, and a third step difference 274 is provided between the fourth slot segment 224 and the fifth slot segment 225, so that the guide column 11 can move unidirectionally in the guide rail 22. Thus, by providing the lifting arc surface 271 on the first slot segment 221 to raise the height of the first slot segment 221, and by providing a first step difference 272 between the second slot segment 222 and the third slot segment 223 (i.e., descending from the second slot segment 222 toward the bottom of the slot segment to the third slot segment 223), the guide post 11 is prevented from returning to the second slot segment 222 after moving to the third slot segment 223 due to the first step difference 272, thereby achieving unidirectional movement of the guide post 11 between the second slot segment 222 and the third slot segment 223. Similarly, by providing a second step difference 273 between the fourth slot segment 224 and the third slot segment 223 (i.e., descending from the third slot segment 223 toward the bottom of the slot segment to the fourth slot segment 224), the guide post 11 is prevented from returning to the third slot segment 223 due to the second step difference 273, thereby achieving unidirectional movement of the guide post 11 between the third slot segment 223 and the fourth slot segment 224. Furthermore, a third step 274 is provided between the fourth slot section 224 and the fifth slot section 225 (i.e., falling from the fourth slot section 224 toward the bottom of the slot section to the fifth slot section 225). Due to the existence of the third step 274, the guide post 11 is prevented from returning to the fourth slot section 224. This allows the guide post 11 to move unidirectionally between the fourth slot section 224 and the fifth slot section 225, thereby effectively preventing the guide post 11 from not moving in a single direction (i.e., "going back") due to insufficient user operation, thereby failing to lock smoothly. Therefore, providing the step difference is conducive to improving the user experience when installing and removing the filter element assembly 20.

[0070] And, refer to Figure 1 、 Figure 2 and Figure 8As shown, the filter element assembly 100 also includes: a limit assembly 30, which is arranged in the turntable assembly 10, and a portion of the limit assembly 30 passes through the guide post 11, and the portion of the limit assembly 30 is retractable relative to the guide post 11, and the length of the portion of the limit assembly 30 extending from the guide post 11 is greater than the radial dimension of the first step difference 272 and / or the second step difference 273 and / or the third step difference 274. In this arrangement, the limit assembly 30 is arranged in the guide post 11, and the limit assembly 30 is retractable relative to the guide post 11, so that when the guide post 11 slides to the first end of the third track, the portion of the limit assembly 30 extends relative to the guide post 11, thereby causing the portion of the limit assembly 30 to be stuck at the first end of the third track. Similarly, when the guide post 11 slides to the first end of the fourth track, the portion of the limit assembly 30 extends relative to the guide post 11, thereby causing the portion of the limit assembly 30 to be stuck at the first end of the fourth track. Furthermore, when the guide post 11 slides to the head end of the fifth track, part of the position-limiting component 30 extends relative to the guide post 11 , thereby causing part of the position-limiting component 30 to be stuck at the head end of the fifth track.

[0071] As well as Figure 2 As shown, the limiting assembly 30 includes: a limiting member 31, a first elastic member 32, and an ejector 33. The elastic member abuts between the ejector 33 and the limiting member 31. The limiting member 31 is fixed to the turntable assembly 10, and the ejector 33 passes through the guide column 11. The ejector 33 extends relative to the guide column 11, and the ejector 33 can always extend relative to the guide column 11 under the elastic force of the first elastic member 32. In addition, the extension size of the ejector 33 relative to the guide column 11 can be changed, and under the action of the first elastic member 32, the ejector 33 always abuts against the guide rail 22. In addition, a limiting member 31 is provided on the turntable assembly 10, and the first elastic member 32 abuts between the ejector 33 and the limiting member 31. The limiting member 31 can fix the first elastic member 32.

[0072] Among them, the limiting member 31 can be a screw or a bolt, that is, the relative position between the limiting member 31 and the turntable assembly 10 is adjustable, so that the compression amount of the first elastic member 32 can be adjusted according to the size of the limiting member 31 extending into the turntable assembly 10, and then the elastic force of the first elastic member 32 can be controlled.

[0073] And, combined Figure 2-Figure 4As shown, a first limiting protrusion 12 is provided on the inner side of the turntable, and a second limiting protrusion 229 is provided on the outer side of the filter element assembly 20. When the filter element assembly 20 is in the locked position, the first limiting protrusion 12 and the second limiting protrusion 229 abut against each other. When the filter element assembly 20 is in the locked position, the first limiting protrusion 12 on the turntable can abut against the second limiting protrusion 229 on the filter element assembly 20, thereby maintaining a relative static state between the filter element assembly 20 and the turntable assembly 10. In addition, the provision of the first limiting protrusion 12 and the second limiting protrusion 229 can improve the carrying capacity of the turntable assembly 10, that is, this allows the turntable assembly 10 to be used with a filter element assembly 20 of larger specifications.

[0074] Further, refer to Figure 2-Figure 4 As shown, there are two first limiting protrusions 12, which are arranged on both sides of the guide column 11, and two second limiting protrusions 229, which are arranged on both sides of the guide rail 22. The two first limiting protrusions 12 and the two second limiting protrusions 229 are matched one by one. In this way, the first limiting protrusions 12 are respectively arranged on both sides of the guide rail 22, and the second limiting protrusions 229 are respectively arranged on both sides of the guide column 11. In this way, the two second limiting protrusions 229 and the two first limiting protrusions 12 abut against each other, thereby further improving the load-bearing capacity of the turntable assembly 10, thereby making the locking between the filter element assembly 20 and the turntable assembly 10 more stable.

[0075] And, refer to Figure 2 、 Figure 3 and Figure 7 As shown, the filter element assembly 100 further includes a reset assembly 40, which is disposed on the side wall of the turntable assembly 10 and abuts between the turntable assembly 10 and the filter element assembly 20 to provide a reset force to the filter element assembly 20. Thus, the reset assembly 40 is disposed on the turntable assembly 10 to provide a reset force to the filter element assembly 20. That is, when the filter element assembly 20 is pressed, the filter element assembly 20 compresses the reset assembly 40, and the reset assembly 40 continues to provide a reset force to the filter element assembly 20.

[0076] When the filter element assembly 20 changes from the unlocked position to the locked position, the filter element assembly 20 is pressed first. At this time, the reset assembly 40 is pressed down and generates a reset force. Then the filter element assembly 20 is released. The filter element assembly 20 moves to the locked position under the push of the reset assembly 40, thereby realizing the locking fit of the filter element assembly 20 and the turntable assembly 10.

[0077] Similarly, when the filter element assembly 20 changes from the locked position to the unlocked position, the filter element assembly 20 is pressed first. At this time, the reset assembly 40 is pressed down and generates a reset force. Then the filter element assembly 20 is released. The filter element assembly 20 moves to the unlocked position under the push of the reset assembly 40, thereby realizing the separation of the filter element assembly 20 and the turntable assembly 10.

[0078] Among them, reference Figure 7 As shown, the first fixing seat 13 is provided on the side of the turntable assembly 10 facing the reset assembly 40. The reset assembly 40 includes a top cover 41 and a first reset member 42. A second fixing seat 411 is provided on the side of the top cover 41 facing the first reset member 42. The first reset member 42 abuts between the first fixing seat 13 and the second fixing seat 411. The first reset member 42 is sandwiched between the top cover 41 and the reset assembly 40, thereby providing a reset force to the top cover 41, and in turn, to the filter element assembly 20. The first reset member 42 may be a spring.

[0079] Reference Figure 7 As described above, the first fixing seat 13 is provided on the side of the turntable assembly 10 facing the reset assembly 40, and the second fixing seat 411 is provided on the side of the top cover 41 facing the first reset member 42. The first reset member 42 abuts between the first fixing seat 13 and the second fixing seat 411. In this way, the first fixing seat 13 is provided on the turntable assembly 10, and the second fixing seat 411 is provided on the top cover 41. In this way, the first reset member 42 can be clamped onto the first fixing seat 13 and the second fixing seat 411, that is, the first reset member 42 can be fixed.

[0080] Furthermore, the turntable assembly 10 is provided with a mounting seat 19, the mounting seat 19 is provided with a first fixing seat 13, and the top cover 41 is sleeved on the outside of the mounting seat 19. The mounting seat 19 is provided on the turntable assembly 10, and the top cover 41 is sleeved on the outside of the mounting seat 19, so that the top cover 41 can move along the extension direction of the mounting seat 19, that is, the top cover 41 can move in the up and down direction, thereby effectively improving the operating stability of the reset assembly 40.

[0081] And, refer to Figure 7As shown, the mounting seat 19 is provided with a slide groove 191, and the top cover 41 is provided with a buckle 412. The buckle 412 slides in the slide groove 191. When the filter element assembly 20 is in the unlocked position, the buckle 412 is engaged with the turntable assembly 10. In this way, the buckle 412 is provided on the top cover 41, and the slide groove 191 is provided on the turntable assembly 10. The buckle 412 can slide in the slide groove 191, thereby allowing the top cover 41 to slide in the slide groove 191. Furthermore, when the filter element assembly 20 is in the unlocked position, the filter element assembly 20 does not apply pressure to the reset assembly 40. The top cover 41 is at its highest point under the reset force of the first reset member 42. At this time, the buckle 412 on the top cover 41 can be engaged with the turntable assembly 10, thereby preventing the top cover 41 and the turntable assembly 10 from separating.

[0082] Furthermore, a relief groove 14 is provided above the turntable assembly 10. When the filter element assembly 20 is in the locked position, part of the top cover 41 fits within the relief groove 14, and the upper surface of the top cover 41 is flush with the upper surface of the turntable assembly 10. That is, the relief groove 14 is provided on the turntable assembly 10, so that when the filter element assembly 20 is in the locked position, part of the top cover 41 can fit within the relief groove 14, thereby reducing the height of the filter element assembly 100 in the vertical direction, thereby achieving a miniaturized design of the water purifier. In addition, when the filter element assembly 20 is in the locked position, the upper surface of the top cover 41 can be flush with the upper surface of the turntable assembly 10, so that the force applied by the filter element assembly 20 to the top cover 41 is evenly distributed to the turntable assembly 10 and the top cover 41, thereby reducing the load on the top cover 41 and preventing the top cover 41 from being damaged when it bears heavy load for a long time.

[0083] Furthermore, there may be at least two reset assemblies 40, and the at least two reset assemblies 40 are spaced apart in the circumferential direction of the turntable assembly 10. In other words, the at least two reset assemblies 40 are provided on the turntable assembly 10. In this way, on the one hand, the weight of the filter element assembly 20 can be shared by the at least two reset assemblies 40, thereby preventing a single reset assembly 40 from bearing a heavy load. On the other hand, the at least two reset assemblies 40 spaced apart in the circumferential direction of the turntable assembly 10 can evenly share the weight of the filter element assembly 20, thereby facilitating the up and down movement of the filter element assembly 20.

[0084] There can be two reset assemblies 40, and the angle between the two reset assemblies 40 is 180 degrees, so that the weight of the filter element assembly 20 can be reasonably shared. Of course, there can also be three, four or more reset assemblies 40.

[0085] In addition, refer to Figure 10-13As shown, the filter cartridge assembly 100 further includes a second reset member 50 connected between the turntable assembly 10 and the waterway plate 60 to provide a reset force to the turntable assembly 10. Specifically, the second reset member 50 is disposed between the turntable assembly 10 and the waterway plate 60 so that when the turntable assembly 10 rotates relative to the waterway plate 60, the second reset member 50 applies a reset force to the turntable assembly 10. Specifically, when the filter cartridge assembly 20 is in the locked position, the turntable assembly 10 rotates relative to the waterway plate 60, causing the second reset member 50 to apply a reset force to the turntable assembly 10. Furthermore, when the filter cartridge assembly 20 is in the unlocked position, the turntable assembly 10 is reset under the action of the second reset member 50. This allows the guide post 11 to align with the entrance of the guide rail 22 during the next reassembly of the filter cartridge assembly 20, thereby facilitating the entry of the guide post 11 into the guide rail 22. This facilitates the next locking between the filter cartridge assembly 20 and the turntable assembly 10.

[0086] According to an optional embodiment of the present invention, Figure 10 and Figure 11 As shown, the second reset member 50 can be a tension spring. A first mounting post 61 is provided on the waterway plate 60, and a second mounting post 15 is provided on the turntable assembly 10. One end of the tension spring is connected to the first mounting post 61, and the other end of the tension spring is connected to the second mounting post 15. In this way, the second reset member 50 is a tension spring connected between the first mounting post 61 of the waterway plate 60 and the second mounting post 15 of the turntable assembly 10, thereby providing a reset force to the turntable assembly 10 through the tension spring.

[0087] In addition, refer to Figure 10 and Figure 11 As shown, a first limiting rib 16 is provided on the outer side of the turntable assembly 10, and a second limiting rib 62 is provided on the waterway plate 60. When the filter element assembly 20 is in the unlocked position, the first limiting rib 16 and the second limiting rib 62 abut against each other. In other words, the provision of the first limiting rib 16 on the turntable assembly 10 and the provision of the second limiting rib 62 on the waterway plate 60 allows the turntable assembly 10 to return to its initial position under the action of the second return member 50 when the filter element assembly 20 is in the unlocked position. That is, the mutual abutment between the first limiting rib 16 and the second limiting rib 62 prevents the turntable assembly 10 from continuing to rotate under the action of the second return member 50.

[0088] According to another optional embodiment of the present invention, Figure 10 and Figure 11As shown, the second reset member 50 can be a torsion spring, a third mounting post 63 and a fourth mounting post 64 are provided on the waterway plate 60, and a fifth mounting post 17 is provided on the turntable assembly 10. The torsion spring is sleeved on the third mounting post 63, with one end of the torsion spring abutting against the fourth mounting post 64, and the other end of the torsion spring abutting against the fifth mounting post 17. In other words, the second reset member 50 is a torsion spring, and the torsion spring is sleeved on the third mounting post 63 of the waterway plate 60, and the two ends of the torsion spring abut against the fourth mounting post 64 and the fifth mounting post 17, respectively. In this way, the torsion spring can apply a reset force to the fifth mounting post 17, thereby driving the turntable assembly 10 to rotate.

[0089] like Figure 10 and Figure 11 As shown, the waterway plate 60 is provided with a third limiting rib 65. When the filter element assembly 20 is in the unlocked position, the third limiting rib 65 and the fifth mounting post 17 abut against each other. In other words, the third limiting rib 65 is provided on the waterway plate 60 so that when the filter element assembly 20 is in the unlocked position, the turntable assembly 10 can return to its initial position under the action of the second return member 50. At this time, the third limiting rib 65 can abut against the fifth mounting post 17, thereby preventing the turntable assembly 10 from continuing to rotate under the action of the second return member 50.

[0090] Furthermore, the fifth mounting post 17 abuts against the third limiting rib 65 , so there is no need to provide an additional abutting structure on the turntable assembly 10 to abut against the third limiting rib 65 , which facilitates the manufacture of the turntable assembly 10 .

[0091] Reference Figure 10-13 As shown, there may be at least two second reset members 50, and the at least two second reset members 50 are circumferentially spaced apart on the outer side of the turntable assembly 10. In other words, at least two second reset members 50 are provided between the turntable assembly 10 and the waterway plate 60, so that the at least two reset assemblies 40 can evenly apply a reset force to the turntable assembly 10, thereby facilitating the circumferential rotation of the turntable assembly 10.

[0092] There may be two second reset members 50, and the angle between the two second reset members 50 is 180°, so that the reset force can be evenly and reasonably applied to the turntable assembly 10. Of course, there may also be three, four or more second reset members 50.

[0093] In addition, refer to Figure 2As shown, the filter element assembly 100 further includes a fixing bracket 70, which is fixed to the waterway plate 60 and abuts against the outer side of the turntable assembly 10. The fixing bracket 70 is disposed on the outer side of the turntable assembly 10 and abuts against the outer side of the turntable assembly 10. This allows the fixing bracket 70 to constrain the turntable assembly 10, preventing the turntable assembly 10 from changing its relative position with the waterway plate 60 during rotation, thereby ensuring stable fit between the filter element assembly 20 and the turntable assembly 10.

[0094] Among them, combined with 2, Figure 3 and Figure 8 As shown, a guide groove 71 is provided on the side of the fixed frame 70 facing the turntable assembly 10, and a guide rib 18 is provided on the outside of the turntable assembly 10. The guide rib 18 extends in the circumferential direction of the outside of the turntable assembly 10, and the guide rib 18 fits in the guide groove 71 and slides in the guide groove 71. That is, the guide rib 18 is provided on the outside of the turntable assembly 10, and the guide groove 71 is provided on the fixed frame 70, so that the guide rib 18 slides in the guide groove 71. In addition, since the guide rib 18 extends in the circumferential direction of the outside of the turntable assembly 10, the guide rib 18 limits the rotation angle of the turntable assembly 10 when sliding in the guide groove 71, ensuring that the turntable assembly 10 can only rotate and will not move along the height direction of the turntable assembly 10.

[0095] And, refer to Figure 4 and Figure 9 As shown, the filter element assembly 20 includes a filter element body 24 and a filter element head 25. The filter element head 25 is provided with a guide rail 22 in one of its length and width directions, and a clearance space 26 in the other of its length and width directions. In other words, the guide rail 22 and the clearance space 26 are not arranged in the same direction of the filter element head 25. As such, the filter element head 25 has a non-circular structure, which prevents the filter element head 25 from being misaligned when mated with the turntable assembly 10, thereby improving the assembly efficiency between the filter element assembly 20 and the turntable assembly 10. Furthermore, the clearance space 26 provided on the filter element head 25 effectively clears other structures on the turntable assembly 10, thereby reducing the radial dimension of the turntable assembly 10 and facilitating the miniaturization of the filter element assembly 10.

[0096] Among them, reference Figure 9 As shown, the filter head 25 has curved surfaces on both sides of its length, each of which is provided with guide rails 22. The filter head 25 has flat surfaces on both sides of its width. In other words, the projection of the filter head 25 on the filter body 24 is composed of an arc and a straight line. This allows the projection of the filter head 25 to be arc-shaped, which prevents errors when mating with the turntable assembly 10 and improves the assembly efficiency between the filter assembly 20 and the turntable assembly 10.

[0097] And, refer to Figure 9 As shown, the distance between at least one second water inlet 21 and the central axis of the filter cartridge head 25 is h1, and the distance between at least another second water inlet 21 and the central axis of the filter cartridge head 25 is h2. h1 and h2 satisfy the relationship: h1≠h2. As such, the center of the line connecting the at least one second water inlet 21 and the at least another second water inlet 21 is not on the central axis of the filter cartridge head 25. That is, the distances between the at least one second water inlet 21 and the at least another second water inlet 21 and the central axis of the filter cartridge head 25 are unequal. This allows the filter cartridge head 25 to function as a foolproof mechanism when mated with the turntable assembly 10, thereby improving the assembly efficiency between the filter cartridge assembly 20 and the turntable assembly 10.

[0098] Among them, reference Figure 1 As shown, a portion of the reset assembly 40 is disposed within the escape space 26. That is, since the reset assembly 40 is disposed on the side wall of the turntable assembly 10, by providing the escape space 26 on the filter cartridge head 25, the escape space 26 can correspond to the portion of the reset assembly 40. This allows for foolproofing during assembly of the filter cartridge assembly 20 through the cooperation between the reset assembly 40 and the escape space 26, while also allowing for the reset assembly 40 to be reasonably disposed on the side wall of the turntable assembly 10.

[0099] Specifically, the avoidance space 26 corresponds to the mounting seat 19 and the top cover 41 .

[0100] The water purifier according to the second embodiment of the present invention includes: a filter element assembly 100.
