Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, specifically to a filter component and a water purifier. Background Technology

[0002] As people's living standards improve, their requirements for drinking water quality are also increasing. Water purifiers with replaceable filter cartridges are widely used due to their cost-saving and long service life.

[0003] Most current filter cartridges are connected to the body by a rotating screw-on method. This rotating screw-on filter cartridge installation structure increases the risk of water leakage, so a complex sealing structure is usually required at the bottom. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a filtering component is provided, the technical solution of which is as follows.

[0005] The filter assembly includes a mounting base, a filter element, a locking assembly, and a disassembly component. The mounting base has a receiving space. The filter element is designed to be inserted into or removed from the receiving space along a first direction. The locking assembly is mounted on the mounting base and has a locking member movable between a first position and a second position along a second direction. When the locking member is in the first position, it engages with the filter element; when it is in the second position, it disengages from the filter element. The second direction is perpendicular to the first direction. The disassembly component is movable relative to the filter element along the first direction between an initial position and a final position. When the disassembly component is in the final position, it is rotatable relative to the filter element in the circumferential direction to a locking position where it engages with the filter element. During the process of the disassembly component moving from the initial position to the final position, a pushing force is provided to the locking member, causing the locking member to move from the first position to the second position.

[0006] The filter assembly of this utility model has a locking member that engages with the filter element when in the first position. The locking member is pushed by the disassembly member to disengage from the filter element when in the second position. The filter element can be installed or removed relative to the mounting base simply by moving in the first direction. Compared with the rotating screw-on structure, the bottom does not need a complicated sealing structure to avoid the risk of water leakage. It is not only simple in structure, but also improves the convenience of operation.

[0007] For example, a limiting groove and a locking groove are formed on the outer wall of the filter element. The limiting groove is arranged along a first direction, and the locking groove is arranged along the circumferential direction. The limiting groove and the locking groove are connected. The disassembly component is provided with a protrusion. The protrusion engages with the limiting groove during the process of the disassembly component moving from the initial position to the final position. When the disassembly component is in the final position, the protrusion rotates a predetermined angle along the circumferential direction and engages with the locking groove. With this configuration, the cooperation between the protrusion and the limiting groove and the locking groove not only ensures a stable connection between the disassembly component and the filter element, but also ensures that the disassembly component can stably remove the filter element from the receiving space. This method of removing the filter element improves the convenience of operation while reducing the risk of leakage.

[0008] For example, the locking member is connected to an elastic element, and after the pushing force is removed, the locking member moves from the second position to the first position via the elastic element. This configuration, on the one hand, reduces or buffers the vibration experienced by the locking member when a pushing force is applied, thereby extending the service life of the locking member; on the other hand, the elastic restoring force of the elastic element drives the locking member to move, simplifying the structure and saving costs.

[0009] For example, the locking assembly also includes a limiting member, with both ends of the elastic member abutting against the limiting member and the locking member, respectively. This configuration ensures that the elastic member can be compressed under the pushing force, so that the locking member can be moved by the elastic restoring force after the pushing force is removed; on the other hand, it avoids collision between the locking member and the limiting member caused by providing a pushing force to the locking member, thereby improving the service life of the locking member and the limiting member.

[0010] For example, a connecting groove is provided on the side of the locking member away from the locking slot, and the limiting member is at least partially inserted into the connecting groove. The two ends of the elastic member abut against the bottom of the limiting member and the connecting groove, respectively. This arrangement avoids the elastic member from moving to the sides of the pushing force when compressed by the pushing force, thus preventing the elastic member from flying out or affecting the compression effect.

[0011] For example, a connecting rod extends from the bottom of the connecting groove, and an elastic element is sleeved on the connecting rod. With this configuration, the locking element can connect elastic elements of different sizes to adapt to different application scenarios and needs; when using small-sized elastic elements, it avoids the phenomenon that small-sized elastic elements move to both sides of the pushing force when compressed by the pushing force, thus affecting the compression effect.

[0012] For example, the limiting member has a limiting surface facing the bottom of the connecting groove. A relief groove is recessed on the limiting member from the limiting surface away from the connecting groove. The elastic member abuts against the limiting surface, and the connecting rod passes through the relief groove. This arrangement avoids the connecting rod abutting against the limiting surface and affecting the compression of the elastic member.

[0013] For example, the locking element has a travel stroke X, the elastic element has a compression stroke Y, and the elastic element has a compressed length L, where X < Y + L. This configuration avoids the locking element colliding with the limiting element due to the application of a pushing force to it, and also prevents the entire structure from losing stability due to excessive compression.

[0014] For example, the disassembly component has a sidewall, and the locking component has a mating ramp. During the process of the disassembly component moving from the initial position to the final position, the locking component is pushed by the mating ramp through the sidewall. This configuration converts the force of the disassembly component moving in the first direction into the pushing force of the locking component moving in the second direction, and ensures that the locking component can be pushed by the sidewall to disengage from the locking groove.

[0015] For example, the locking groove has a bottom wall, and the locking member has an end opposite to the bottom wall. The mating inclined portion extends outward and upward from the end relative to the bottom wall. This configuration not only converts the force of the disassembly member moving in the first direction into the pushing force of the locking member moving in the second direction, but also simplifies the structure and saves costs.

[0016] For example, the disassembly component has a top wall connected to the side wall, a protrusion disposed on the inner side surface of the side wall, and a gripping portion formed on the top wall. This configuration, on the one hand, facilitates the engagement of the protrusion with the limiting groove and the locking groove on the inner side surface of the side wall; on the other hand, the gripping portion facilitates the user's hand operation of the disassembly component, thereby improving ease of operation.

[0017] For example, a guide wall extends from the mounting base into the receiving space, dividing the receiving space into a guide cavity and a receiving cavity. This arrangement provides better guidance for the filter element to be inserted into the receiving space along the first direction and improves the stability of the filter element during movement.

[0018] For example, a mounting hole is provided on the guide wall, and the locking member passes through the mounting hole. With this configuration, the mounting hole provides a good limiting effect when the locking member moves in the second direction, and improves the stability of the locking member during movement.

[0019] For example, a stop portion is formed on the side of the latching member away from the latching groove. The stop portion is located within the receiving cavity, and when the latching member is in the first position, the stop portion abuts against the guide wall. This arrangement not only prevents the latching member from dislodging from the mounting hole and falling into the guide cavity, but also reduces the possibility of the latching member colliding with the bottom wall of the latching groove.

[0020] For example, the filter element has a first end face and a second end face opposite each other along a first direction, and the locking groove is closer to the second end face than the first end face. This arrangement brings the locking groove closer to the user, facilitating its engagement with the disassembly component, saving material used in manufacturing the sidewalls of the disassembly component, and reducing costs.

[0021] For example, the retaining groove divides the filter element into a first section and a second section. The first section is connected to a first end face, and the second section is connected to a second end face. The diameter of the second section is smaller than that of the first section. With this configuration, when the filter element is located within the receiving space, the disassembly component can engage with the second section, thereby disengaging the retaining component from the retaining groove. This ensures that the disassembly component can smoothly remove the filter element from the receiving space.

[0022] For example, a limiting groove is provided on the second segment. This arrangement places the limiting groove close to the user setting, facilitating the engagement of the protrusion with the limiting groove.

[0023] For example, there are multiple limiting grooves, which are spaced apart along the circumferential direction on the second segment. This arrangement ensures that, in the case of multiple protrusions, the multiple protrusions can be easily matched with the multiple limiting grooves one by one.

[0024] According to another aspect of this utility model, a water purifier is provided, which includes a body and a filter assembly as described above, the filter assembly being disposed on the body. Since the filter assembly as described above has the aforementioned beneficial effects, the water purifier including the filter assembly as described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0040] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0041] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0042] This invention provides a filter assembly. The filter assembly provided by this invention can be applied to water purifiers. The following will describe in detail a filter assembly according to an embodiment of this invention with reference to the accompanying drawings.

[0043] See also Figures 1 to 5 The filter assembly 10 may include a mounting base 100, a filter element 200, a locking assembly 300, and a removal component 400. The mounting base 100 may have a receiving space 110. The filter element 200 may be configured to be inserted into or removed from the receiving space 110 along a first direction OO. The first direction OO can be the direction in which the filter element 200 is installed or removed relative to the mounting base 100. The locking assembly 300 may be disposed on the mounting base 100, and the locking assembly 300 has a locking member 310 movable along a second direction PP between a first position and a second position. The locking member 310 is engaged with the filter element 200 in the first position and disengaged from the filter element 200 in the second position. The second direction PP can be the direction in which the locking member 310 is engaged or disengaged relative to the filter element 200. The second direction PP and the first direction OO may be perpendicular. The removal component 400 is installable or detachable relative to the filter element 200. When it is necessary to remove the filter element 200 from the receiving space 110, the disassembly piece 400 can be installed onto the filter element 200. The disassembly piece 400 is movable relative to the filter element 200 along the first direction OO between an initial position and a final position. When the disassembly piece 400 is in the final position, it is movable relative to the filter element 200 in the circumferential direction QQ (e.g., ...). Figure 9 The disassembly component 400 can be rotated to a snap-fit ​​position that engages with the filter element 200. During the movement of the disassembly component 400 from its initial position to its final position, a pushing force can be applied to the locking component 310, causing it to move from a first position to a second position. After removing the filter element 200 from the receiving space 110, the disassembly component 400 can be removed from the filter element 200. The disassembly component 400 is rotated from its snap-fit ​​position along the circumferential direction QQ to its final position. With the disassembly component 400 in its final position, it is moved relative to the filter element 200 along the first direction OO from its final position back to its initial position.

[0044] In this utility model, the filter assembly 10 has a locking member 310 that engages with the filter element 200 when in the first position. The disassembly member 400 provides a pushing force to the locking member 310, causing it to disengage from the filter element 200 in the second position. The filter element 200 can be installed or removed from the mounting base 100 simply by moving along the first direction OO. Compared with the rotating and screwing structure, the bottom does not require a complex sealing structure to avoid the risk of leakage. This not only simplifies the structure but also improves the ease of operation.

[0045] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9 A limiting groove 210 and a locking groove 220 can be formed on the outer wall of the filter element 200. The limiting groove 210 can be set along the first direction OO. The locking groove 220 can be set along the circumferential direction QQ. The limiting groove 210 can communicate with the locking groove 220. A protrusion 410 can be provided on the disassembly part 400. The protrusion 410 can engage with the limiting groove 210 during the process of the disassembly part 400 moving from the initial position to the final position, and when the disassembly part 400 is in the final position, the protrusion 410 can rotate a predetermined angle along the circumferential direction QQ to engage with the locking groove 220. It should be noted that when the disassembly part 400 is in the final position, the protrusion 410 can enter the locking groove 220 from the limiting groove 210, and the protrusion 410 cannot continue to move towards the locking groove 220 along the first direction OO. Specifically, when two limiting grooves 210 are provided, and the included angle between the two limiting grooves 210 is 180°, the preset angle is less than 180°. The preset angle can also be other angles, as long as the protrusion 410 can rotate QQ in the circumferential direction away from the limiting groove 210, and the protrusion 410 can be engaged with the locking groove 220. In this way, through the cooperation of the protrusion 410 with the limiting groove 210 and the locking groove 220, not only is the disassembly part 400 stably connected to the filter element 200, but it also ensures that the disassembly part 400 can stably remove the filter element 200 from the receiving space 110. This method of removing the filter element 200 improves the convenience of operation while reducing the risk of leakage.

[0046] See Figure 5 The locking member 310 can be connected to an elastic member 320. After the pushing force is removed, the locking member 310 can move from the second position to the first position via the elastic member 320. Specifically, the elastic member 320 can be a spring or the like. On the one hand, when a pushing force is applied, the elastic member 320 can reduce or buffer the vibration experienced by the locking member 310, thereby increasing the service life of the locking member 310; on the other hand, the elastic restoring force of the elastic member 320 drives the locking member 310 to move, simplifying the structure and saving costs.

[0047] See also Figure 4 and Figure 5 The locking assembly 300 may further include a limiting member 330. The two ends of the elastic member 320 can respectively abut against the limiting member 330 and the locking member 310. On the one hand, this ensures that the elastic member 320 can be compressed under a pushing force, so that the locking member 310 can be moved by the elastic restoring force after the pushing force is removed; on the other hand, it avoids collision between the locking member 310 and the limiting member 330 caused by providing a pushing force to the locking member 310, thereby improving the service life of the locking member 310 and the limiting member 330.

[0048] In some embodiments, the two ends of the elastic member 320 can be connected to the limiting member 330 and the locking member 310, respectively. Specifically, the elastic member 320 can be connected to the limiting member 330 and the locking member 310 by means of bonding or welding. In this way, it is further ensured that the elastic member 320 can be compressed under the pushing force, so that the locking member 310 can be moved by the elastic restoring force after the pushing force is removed.

[0049] In some embodiments, a guide rod or guide rail may be provided on the locking member 310 or the limiting member 330, and the elastic member 320 is connected to the guide rod or guide rail to ensure that the elastic member 320 can be stably compressed along the second direction PP and can stably rebound along the second direction PP. Specifically, the locking member 310 may have a mating surface that faces the limiting member 330, and a guide rod may be formed on the locking member 310 from the mating surface toward the limiting member 330, and the elastic member 320 may be sleeved on the guide rod. The limiting member 330 may have a limiting surface 331 that faces the locking member 310, and a relief groove 332 is recessed on the limiting member 330 from the limiting surface 331 away from the locking member 310, and the guide rod may pass through the relief groove 332. This avoids the elastic element 320 from moving to either side of the pushing force when compressed by the pushing force, thus preventing the elastic element 320 from flying out or affecting the compression effect.

[0050] See also Figure 5 and Figure 6 A connecting groove 311 may be provided on the side of the locking member 310 away from the locking groove 220. The limiting member 330 may be at least partially inserted into the connecting groove 311. The two ends of the elastic member 320 may respectively abut against the limiting member 330 and the bottom of the connecting groove 311. Preferably, when the elastic member 320 is installed in the connecting groove 311, the elastic member 320 may fit against the side wall of the connecting groove 311. This avoids the elastic member 320 from moving to either side of the pushing force when compressed by the pushing force, thus preventing the elastic member 320 from flying out or affecting the compression effect.

[0051] See again Figure 5 and Figure 6A connecting rod 3111 can extend from the bottom of the connecting groove 311. The connecting rod 3111 and the locking member 310 can be an integral structure. Of course, the connecting rod 3111 and the locking member 310 can also be separate structures, for example, the connecting rod 3111 and the locking member 310 can be connected together by means of adhesive or screws. The elastic member 320 can be sleeved on the connecting rod 3111. Preferably, when the elastic member 320 is sleeved on the connecting rod 3111, the elastic member 320 can fit snugly against the connecting rod 3111. In this way, the locking member 310 can connect elastic members 320 of different sizes to adapt to different application scenarios and needs; when using small-sized elastic members 320, it avoids the phenomenon that the small-sized elastic members 320 move to both sides of the pushing force when compressed by the pushing force, thus avoiding the phenomenon that affects the compression effect.

[0052] See also Figures 4 to 7 The limiting member 330 may have a limiting surface 331. The limiting surface 331 may face the bottom of the connecting groove 311. The limiting member 330 may have a recessed relief groove 332 extending from the limiting surface 331 away from the connecting groove 311. The elastic member 320 may abut against the limiting surface 331. When the locking member 310 is in the first position, the connecting rod 3111 may pass through the relief groove 332. In this way, the connecting rod 3111 abutting against the limiting surface 331 and affecting the compression of the elastic member 320 is avoided.

[0053] In some embodiments, the limiting member 330 may have a limiting portion 333 and a fixing portion 334, and the limiting portion 333 can be connected to the mounting base 100 through the fixing portion 334. The limiting portion 333 and the fixing portion 334 can be an integral structure. The limiting portion 333 and the fixing portion 334 can also be a separate structure, for example, the limiting portion 333 and the fixing portion 334 can be connected together by means of adhesive or screws. The fixing portion 334 and the mounting base 100 can be connected together by means of welding or screws. The elastic member 320 can abut against the limiting portion 333 and the locking member 310 respectively. In this way, the limiting portion 333 is fixedly mounted on the mounting base 100 relative to the locking member 310 to ensure that the elastic member 320 can be compressed under the pushing force.

[0054] See Figure 5 The locking element 310 can have a travel stroke X, the elastic element 320 can have a compression stroke Y, and the elastic element 320 can have a compressed length L, where X < Y + L. In this way, it is avoided that the locking element 310 will collide with the limiting element 330 due to the pushing force applied to the locking element 310, and the entire structure is prevented from losing stability due to excessive compression.

[0055] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The disassembly member 400 may have a sidewall 420. The locking member 310 may have a mating ramp 312. During the process of the disassembly member 400 moving from the initial position to the final position, the locking member 310 can be pushed by the sidewall 420 and the mating ramp 312. In this way, the force of the disassembly member 400 moving in the first direction OO is converted into the pushing force of the locking member 310 moving in the second direction PP, and it is ensured that the locking member 310 can be pushed by the sidewall 420 to disengage from the locking groove 220.

[0056] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 The locking groove 220 may have a bottom wall 221. The locking member 310 may have an end opposite to the bottom wall 221. The mating ramp 312 may be inclined outward and upward from the end relative to the bottom wall 221. In this way, not only is the force of the disassembly member 400 moving in the first direction OO converted into the pushing force of the locking member 310 moving in the second direction PP, but the structure is also simple and cost-effective.

[0057] In some embodiments, in conjunction with reference Figure 5 , Figure 8 , Figure 9 and Figure 10 The bottom wall 221 of the locking groove 220 can be connected to a first wall 222 and a second wall 223 on both sides. The locking member 310 can have a locking engagement wall 313 that cooperates with the first wall 222. When the locking member 310 is in the first position, the first wall 222 and the locking engagement wall 313 can abut against each other. When the locking member 310 is in the second position, the first wall 222 and the locking engagement wall 313 can disengage. The first wall 222 can be a planar structure, and the locking engagement wall 313 can be a planar structure to facilitate the abutment or disengagement of the first wall 222 and the locking engagement wall 313. When the disassembly member 400 removes the filter element 200 from the receiving space 110, the protrusion 410 abuts against the second wall 223. This structure is simple and easy to manufacture.

[0058] See also Figure 2 , Figure 8 and Figure 9The disassembly component 400 may have a top wall 430 connected to the side wall 420. A protrusion 410 may be provided on the inner surface 421 of the side wall 420. A gripping portion 431 may be formed on the top wall 430 of the disassembly component 400. The gripping portion 431 and the top wall 430 may be an integral structure. Alternatively, the gripping portion 431 and the top wall 430 may be separate structures, for example, connected together by adhesive or screws. On one hand, the protrusion 410 is provided on the inner surface 421 of the side wall 420, facilitating its engagement with the limiting groove 210 and the locking groove 220; on the other hand, the gripping portion 431 facilitates user hand operation of the disassembly component 400, thereby improving ease of operation.

[0059] Specifically, the gripping part 431 may have a rod part 4311 and a head 4312. The rod part 4311 may be connected between the head 4312 and the top wall 430. This facilitates the user's gripping and also makes it easier for the user to remove the filter element 200 from the receiving space 110 when the disassembly part 400 removes it, avoiding the situation where the user might easily slip out of their hand when grasping the rod part 4311 alone.

[0060] See also Figure 2 and Figure 4 A guide wall 120 may extend from the mounting base 100 into the receiving space 110. The guide wall 120 can divide the receiving space 110 into a guide cavity 111 and a receiving cavity 112. The guide cavity 111 and the receiving cavity 112 can be connected. In this way, it plays a better guiding role for the filter element 200 to be inserted into the receiving space 110 along the first direction OO, and improves the stability of the filter element 200 during movement.

[0061] See again Figures 1 to 5 A mounting hole 121 may be provided on the guide wall 120. The guide cavity 111 and the receiving cavity 112 can be connected through the mounting hole 121. The locking member 310 can pass through the mounting hole 121. When the locking member 310 is in the first position, a part of the locking member 310 can be placed in the guide cavity 111, and another part can pass through the mounting hole 121 and be placed in the receiving cavity 112. When the locking member 310 is in the second position, the locking member 310 is completely removed from the guide cavity 111, which not only ensures that the locking member 310 is disengaged from the locking groove 220, but also avoids obstructing the removal of the filter element 200 from the receiving space 110. In this way, the mounting hole 121 plays a good limiting role when the locking member 310 moves along the second direction PP, and improves the stability of the locking member 310 during movement.

[0062] See also Figures 4 to 6A stop portion 314 may be formed on the side of the latching member 310 away from the latching groove 220. The stop portion 314 may extend from the outer wall surface of the latching member 310. The stop portion 314 may be an integral structure with the latching member 310. Of course, the stop portion 314 and the latching member 310 may also be separate structures, for example, connected together by means of adhesive or screws. The stop portion 314 may be located within the receiving cavity 112. When the latching member 310 is in the first position, the stop portion 314 may abut against the guide wall 120. In this way, not only is it prevented that the latching member 310 will disengage from the mounting hole 121 and fall into the guide cavity 111, but the possibility of the latching member 310 colliding with the bottom wall 221 of the latching groove 220 is also reduced.

[0063] In some embodiments, there may be multiple mounting holes 121, which are spaced circumferentially on the guide wall 120. Correspondingly, there may be multiple locking components 300, each corresponding to a mounting hole 121. Specifically, the number of mounting holes 121 can be 2 to N, where N is a natural number. When there are three mounting holes 121, the angle between any two mounting holes 121 can be 120°, and a locking component 300 is inserted into each mounting hole 121, with the angle between any two locking components 300 being 120°, to ensure that the locking components 300 are evenly distributed around the filter element 200. This further enhances the stability of the connection between the locking components 300 and the filter element 200.

[0064] See also Figure 1 , Figure 4 , Figure 8 , Figure 9 and Figure 10 The filter element 200 may have a first end face 230 and a second end face 240 along the first direction OO. The first end face 230 is the side of the filter element 200 that mates with the mounting base 100. The second end face 240 is the side of the filter element 200 that faces the user after it is installed in the mounting base 100. Compared to the first end face 230 and the second end face 240, the locking groove 220 can be closer to the second end face 240. In this way, the locking groove 220 is positioned closer to the user, which facilitates the engagement of the locking groove 220 with the disassembly part 400, saving material in manufacturing the side wall 420 of the disassembly part 400 and reducing costs.

[0065] In some embodiments, the first end face 230 may be provided with an interface for connecting to the water channel, and a sealing ring may be provided on the interface. This not only facilitates the insertion and removal of the filter element 200, but also improves the sealing between the filter element 200 and the mounting base 100.

[0066] In some embodiments, the filter element 200 is cylindrical in shape. This helps to achieve a more uniform fluid flow, thereby improving filtration efficiency and effectiveness.

[0067] See also Figure 1 , Figure 2 , Figure 9 and Figure 10 The retaining groove 220 divides the filter element 200 into a first segment 250 and a second segment 260. The first segment 250 can be connected to the first end face 230, and the second segment 260 can be connected to the second end face 240. The diameter D2 of the second segment 260 can be smaller than the diameter D1 of the first segment 250. This means the second segment 260 is closer to the user than the first segment 250. Thus, when the filter element 200 is located within the receiving space 110, the disassembly member 400 can engage with the second segment 260, thereby disengaging the retaining member 310 from the retaining groove 220, ensuring that the disassembly member 400 can smoothly remove the filter element 200 from the receiving space 110.

[0068] In some embodiments, the diameter D3 of the disassembly member 400 may be equal to the diameter D1 of the first segment 250. When the filter element 200 is located within the accommodating space 110, the disassembly member 400 can cooperate with the second segment 260, and when the disassembly member 400 is installed on the second segment 260, the overall integrity of the filter element 200 and the disassembly member 400 is strengthened.

[0069] See also Figures 8 to 10 The limiting groove 210 can be set on the second segment 260. In this way, the limiting groove 210 is close to the user setting, which makes it easy for the protrusion 410 to cooperate with the limiting groove 210.

[0070] See also Figure 8 and Figure 9 Multiple limiting grooves 210 can be provided. These multiple limiting grooves 210 can be spaced QQ apart along the circumferential direction on the second segment 260. Multiple protrusions 410 can also be provided, and these multiple protrusions 410 can be spaced QQ apart along the circumferential direction on the sidewall 420. This ensures that, with multiple protrusions 410, they can easily correspond one-to-one with the multiple limiting grooves 210, enhancing the stability of the connection between the protrusions 410 and the filter element 200.

[0071] According to another aspect of the present invention, a water purifier is provided. The water purifier may include a body and a filter assembly 10 as described above. The filter assembly 10 may be disposed on the body. Since the filter assembly 10 described above has the aforementioned beneficial effects, the water purifier including the filter assembly 10 described above also has the aforementioned beneficial effects, which will not be elaborated further here.
