Description

Technical Field

[0001] This utility model relates to the field of water purification equipment, and in particular to a filter cartridge positioning component and a water purification device. Background Technology

[0002] In existing water purification systems, the design for removing filter cartridges is often not user-friendly, making the process cumbersome. Because the connection between the filter cartridge and the device is usually quite tight, and there's a lack of an easy disassembly mechanism, users often encounter jamming issues when replacing the cartridge. The joint between the filter cartridge and the device is prone to disassembly due to scale, impurities, or an overly tight seal, sometimes requiring additional tools. This inconvenient disassembly process not only increases the difficulty for users but may also damage the device itself, affecting its long-term stability and performance. Utility Model Content

[0003] Therefore, it is necessary to provide a filter cartridge positioning component and a water purification device to address the problem of inconvenient filter cartridge disassembly.

[0004] A filter cartridge positioning assembly includes a water channel plate with multiple channels; a handle assembly rotatably mounted on the water channel plate; and a filter cartridge comprising a filter cartridge body and multiple water pipes disposed on the filter cartridge body, the multiple water pipes being adapted to the multiple channels. When the handle assembly rotates relative to the water channel plate, it can lock or separate from the filter cartridge. A pushing portion is formed on the handle assembly, and a blocking portion is formed on the filter cartridge. The pushing portion and the blocking portion are adapted to each other. When the handle assembly rotates relative to the water channel plate, it can abut against or separate from the filter cartridge.

[0005] The first aspect of this application discloses a filter cartridge positioning assembly. The water circuit plate has multiple channels that precisely connect with the water pipes on the filter cartridge, ensuring stable positioning of the filter cartridge on the water circuit plate. Each water pipe is adapted to a corresponding channel, ensuring smooth water flow through the filter cartridge and preventing water dispersion or leakage caused by improper installation or loosening. This design effectively improves the filtration performance of the filter cartridge and the sealing of the water flow channels. The handle assembly is rotatably mounted on the water circuit plate; rotation allows for locking or separation from the filter cartridge, simplifying the installation and replacement process. Traditional filter cartridge replacement often requires complex disassembly steps, while this design allows users to easily install and remove the filter cartridge without additional tools, improving operational efficiency and making it particularly suitable for daily maintenance. The push and stop parts work together; when the handle assembly is rotated, the push part pushes the stop part, ensuring smooth separation of the filter cartridge from the water circuit plate. This structure avoids the problems of loose filter cartridge fixation or damage that may occur with traditional disassembly methods. This design ensures that the filter element is not easily damaged or cannot be separated smoothly during disassembly.

[0006] In one embodiment, the handle assembly includes a handle body, a rotating shaft, and a pusher. The rotating shaft is mounted on the handle body and rotatably mounted on the water channel plate. The pusher is mounted on the handle body and is adapted to the baffle. The rotating shaft allows the handle body to rotate flexibly and reliably. The adaptation of the pusher and baffle allows the user to precisely engage the baffle and pusher by simply rotating the handle assembly, smoothly and stably pushing the filter element, further improving operational convenience. The design of the pusher and baffle ensures stability and safety during filter element removal and installation. The pusher precisely engages with the filter element in the water channel plate by pushing the baffle, allowing the filter element to be stably locked or removed, preventing filter element damage or leakage due to improper operation. Furthermore, this structural design effectively resists filter element loosening under external forces, ensuring that the filter element maintains good sealing during operation.

[0007] In one embodiment, the pushing part includes a pushing rib disposed on the handle body, and the blocking part includes a lug disposed on the filter element body. When the handle assembly rotates relative to the water channel plate, it has at least a first position and a second position. When the handle assembly is in the first position, the length of the water pipe within the channel is L1, and the pushing rib is located between the rotating shaft and the lug. When the handle assembly is in the second position, the length of the water pipe within the channel is L2, where L2 is less than L1. When the handle assembly rotates from the first position to the second position, the pushing rib abuts against the lug. This abutting design between the pushing rib and the lug ensures precise control of the lengths L1 and L2 of the water pipe within the channel during the transition between the first and second positions. This design makes the movement of the filter element controllable, ensuring precise configuration of the water pipe in different positions and preventing incorrect installation or separation of the filter element due to misoperation.

[0008] In one embodiment, the push-up portion further includes a locking rib disposed on the handle body. A clearance space is provided between the locking rib and the push-up rib. When the handle assembly is in the first position, the lug is located within the clearance space and between the locking rib and the push-up rib. During at least a portion of the rotation of the handle assembly from the second position to the first position, the locking rib abuts against the lug. The clearance space between the locking rib and the push-up rib provides the necessary gap, preventing direct friction between the locking rib / push-up rib and the lug. This avoids wear on components due to friction caused by operation or frequent rotation, extending the service life of the handle assembly and filter-related components. Especially after prolonged use, it avoids damage to components that may be caused by excessive friction.

[0009] In one embodiment, there are two push ribs located on opposite sides of the handle body, and two lugs located on opposite sides of the filter element body. The two push ribs, positioned on opposite sides of the handle body, ensure more even force distribution during operation, preventing potential shifts or instability caused by excessive force concentration on one side. This symmetrical arrangement ensures smooth operation, making the entire assembly more stable during rotation, avoiding unnecessary twisting or pressure concentration, and thus protecting the durability of each component.

[0010] In one embodiment, the pushing part includes a limiting plate disposed on the handle body. The side of the filter element body away from the water channel plate forms an inclined surface. The blocking part includes the inclined surface. The handle body has a limiting notch, and the limiting plate is located on the inner wall of the limiting notch. The limiting plate is adapted to the inclined surface. When the handle assembly rotates relative to the water channel plate, it has at least a third position and a fourth position. When the handle assembly is in the third position, the length of the water pipe within the channel is L3. When the handle assembly is in the fourth position, the length of the water pipe within the channel is L4, where L4 is less than L3. When the handle assembly is in the third position, the limiting plate abuts against the inclined surface. The adaptation of the limiting plate and the inclined surface provides a clear physical stop position when the handle assembly rotates to the third position. The cooperation between the limiting plate and the inclined surface ensures the stability of the filter element body in the water channel plate, preventing the filter element from shifting or loosening due to external forces or vibrations. This design ensures that the filter element remains in the accurate and predetermined position during operation, improving the stability and functional reliability of the device.

[0011] In one embodiment, the handle body includes a toggle plate and a locking plate. The toggle plate is arc-shaped, and the rotating shaft is disposed on the toggle plate at both ends. An allowance space adapted to the filter element body is formed on the inner side of the toggle plate. The locking plate is disposed on the toggle plate and covers part of the allowance space. A limiting plate is connected to both the toggle plate and the locking plate. The toggle plate, with its arc shape and allowance space adapted to the filter element body, locks the filter element body in place. The locking plate, covering part of the allowance space, primarily provides additional support. Working together with the toggle plate, the locking plate reinforces and ensures the filter element is securely installed. This design effectively prevents the filter element from loosening or shifting after installation, ensuring its stability and sealing during operation.

[0012] In one embodiment, the number of limiting plates is multiple, and the multiple limiting plates are arranged at intervals. Increasing the number of limiting plates allows the pressure or friction force borne by each limiting plate to be distributed, avoiding wear caused by excessive force on a single limiting plate. Distributing the load can reduce localized wear, help improve the durability of the device, and extend the service life of the components.

[0013] In one embodiment, a positioning part and a limiting part are further included. One of the positioning part and the limiting part is disposed on the handle assembly, and the other of the positioning part and the limiting part is disposed on the filter element. The positioning part and the limiting part are adapted to each other. The positioning part and the limiting part effectively prevent unnecessary movement of the filter element during operation. Through the adapted positioning and limiting action, the position of the filter element in the device is firmly fixed, so that the filter element will not loosen or shift during normal use. This not only enhances the stability of the filter element in the water system, but also avoids leakage or performance degradation problems caused by improper filter element positioning.

[0014] In one embodiment, the positioning part is a protrusion, and the limiting part is a groove. The protrusion is disposed on the handle assembly, and the groove is located on the filter element. The protrusion can engage with the groove. This engaging design provides a physical locking mechanism, ensuring that the filter element will not loosen or fall off due to external force or vibration during operation. By engaging with the groove, the protrusion effectively locks the filter element, preventing accidental displacement or detachment during device use. This robust connection not only improves safety but also ensures stable operation of the device over long-term use, preventing leaks or incomplete filtration.

[0015] In one embodiment, the water pipe includes a pipe body and a sealing ring. The pipe body is disposed on the filter element body, and a first step is formed on the outer wall of the pipe body. A second step is formed on the inner wall of the channel, and the second step is adapted to the first step. The sealing ring is located at the first step. The fit between the first and second steps provides a robust connection mechanism. This step-fitting design ensures that the water pipe can be stably positioned within the channel, avoiding loosening or misalignment due to external forces or vibrations. The step structure enhances sealing through precise engagement, ensuring that water flow does not leak along the interface, thereby improving the sealing performance of the equipment and preventing leakage problems. Due to the step-fitting design, the connection between the water pipe and the channel has higher reliability and stability. During long-term use, the step structure can effectively mitigate wear or loosening caused by repeated loading and unloading, external forces, or vibrations. Therefore, the step design helps improve the durability of the equipment, extend its service life, and reduce maintenance needs caused by loose parts or leaks.

[0016] In one embodiment, the pushing part includes a pushing rib, a limiting plate, and a locking rib. The handle body has a limiting notch, and clearance spaces are provided on opposite sides of the limiting notch. The limiting plate and the locking rib are located on opposite sides of the clearance spaces. The blocking part includes a lug and an inclined surface. The lug is disposed on the filter body and located on opposite sides of the filter body. The inclined surface is formed on the side of the filter body away from the water channel plate. The lug is adapted to the clearance space. When the handle assembly rotates relative to the water channel plate, it has at least a first position and a second position. When the handle assembly is in the first position, the length of the water pipe within the channel is L1, and the push rib is located between the rotating shaft and the lug. When the handle assembly is in the second position, the length of the water pipe within the channel is L2, where L2 is less than L1. When the handle assembly rotates from the first position to the second position, the push rib abuts against the lug. When the handle assembly rotates from the second position to the first position, the locking rib abuts against the lug. When the handle assembly is in the second position, the limiting plate abuts against the inclined surface. Through the cooperation of the push rib, the limiting plate, the locking rib, and the clearance space, the handle assembly can rotate precisely and ensure reliable contact and locking with the filter body at different positions. Specifically, when the handle assembly rotates from the first position to the second position, the push rib abuts against the lug, forming a physical engagement, thereby ensuring the stable position of the water pipe within the channel. This design improves the connection stability between the filter assembly and the water circuit board, avoiding loosening or misalignment caused by vibration or other external factors. The precise contact between the push rib and the lug, along with the locking rib, allows the handle assembly to easily rotate between different positions and lock into the desired location. Operators can easily install, remove, and replace the filter element simply by rotating the handle assembly. This simplified operation reduces the complexity of manual adjustments, improves the user experience, and prevents leaks or damage caused by improper operation. The contact design between the limiting plate and the inclined surface ensures that the handle assembly accurately stops at a specific position during rotation. When the handle assembly is rotated to the second position, the limiting plate abuts against the inclined surface, ensuring the filter element is in the correct position and preventing misoperation due to improper handling. Through this precise positioning mechanism, users can more easily and reliably install and replace the filter element.

[0017] The second aspect of this application discloses a water purification device, which includes the above-described filter positioning assembly.

[0018] The second aspect of this application discloses a water purification device in which a filter cartridge positioning assembly is used. This assembly utilizes a pusher and a baffle to ensure smooth separation of the filter cartridge from the water circuit board when the handle assembly is rotated. This structure avoids the problems of loose or damaged filter cartridges that may occur with traditional disassembly methods. This design ensures that the filter cartridge is less likely to be accidentally damaged or unable to separate smoothly during disassembly. Attached Figure Description

[0036] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0038] The filter cartridge positioning assembly and water purification device of this utility model are described below with reference to the accompanying drawings.

[0039] Example 1

[0040] like Figures 1 to 13 As shown, this embodiment discloses a filter element positioning assembly, which includes a water channel plate 1 with multiple channels 101; a handle assembly 2 rotatably mounted on the water channel plate 1; and a filter element 3, which includes a filter element body 31 and water pipes 32 disposed on the filter element body 31. Multiple water pipes 32 are adapted to the multiple channels 101. When the handle assembly 2 rotates relative to the water channel plate 1, it can lock the filter element 3 or separate from it. A pushing part 23 is formed on the handle assembly 2, and a blocking part 33 is formed on the filter element 3. The pushing part and the blocking part are adapted to each other. When the handle assembly 2 rotates relative to the water channel plate 1, it can abut against or separate from the filter element 3.

[0041] The first aspect of this application discloses a filter cartridge positioning assembly. A water circuit plate 1 has multiple channels 101, which precisely connect with the water pipes 32 on the filter cartridge 3, ensuring the filter cartridge is stably positioned on the water circuit plate. Each water pipe 32 is adapted to a corresponding channel 101, ensuring smooth water flow through the filter cartridge and preventing water dispersion or leakage caused by improper installation or loosening. This design effectively improves the filtration performance of the filter cartridge and the sealing of the water flow channels. A handle assembly 2 is rotatably mounted on the water circuit plate 1, and can be locked or separated from the filter cartridge 3 by rotation, simplifying the installation and replacement process of the filter cartridge. Traditional filter cartridge replacement often requires complex disassembly steps, while this design allows users to easily complete the installation and removal of the filter cartridge without additional tools, improving operational efficiency and making it particularly suitable for daily maintenance. A push part 23 and a baffle part 33 work together; when the handle assembly 2 is rotated, the push part pushes the baffle part, ensuring smooth separation of the filter cartridge from the water circuit plate. This structure avoids the problems of loose or damaged filter elements that may occur with traditional disassembly methods. This design ensures that the filter element is less likely to be accidentally damaged or unable to be easily separated during disassembly.

[0042] like Figure 11 and Figure 12 As shown, in addition to the features of the above embodiments, this embodiment further defines: the handle assembly 2 includes a handle body 21, a rotating shaft 22, and a pushing part 23. The rotating shaft 22 is disposed on the handle body 21 and rotatably mounted on the water channel plate 1. The pushing part 23 is disposed on the handle body 21 and is adapted to the baffle part 33. The rotating shaft 22 allows the handle body 21 to rotate flexibly and reliably. Through the adaptation of the pushing part 23 and the baffle part 33, the user only needs to rotate the handle assembly to precisely push the baffle part 33 and the pushing part 23 together, smoothly and stably pushing the filter element, further improving the convenience of operation. The design of the cooperation between the pushing part 23 and the baffle part 33 ensures the stability and safety of the filter element during disassembly or installation. The pushing part 23 precisely cooperates with the filter element in the water channel plate by pushing the baffle part, so that the filter element can be stably locked or disassembled, avoiding damage or leakage of the filter element due to improper operation. In addition, this structural design can effectively resist the problem of filter element loosening under external force, ensuring that the filter element always maintains good sealing during operation.

[0043] like Figure 11 and Figure 12As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the push-up part 23 includes a push-up rib 231, which is disposed on the handle body 21; the baffle part 33 includes a lug 331, which is disposed on the filter body 31; when the handle assembly 2 rotates relative to the water channel plate 1, it has at least a first position and a second position; when the handle assembly 2 is in the first position, the length of the water pipe 32 in the channel 101 is L1, and the push-up rib 231 is located between the rotating shaft 22 and the lug 331; when the handle assembly 2 is in the second position, the length of the water pipe 32 in the channel 101 is L2, where L2 is less than L1; when the handle assembly 2 rotates from the first position to the second position, the push-up rib 231 abuts against the lug 331. Through the abutting design between the push-up rib 231 and the lug 331, it is ensured that the lengths L1 and L2 of the water pipe 32 in the channel 101 can be precisely controlled during the transition between the first and second positions of the handle assembly 2. This design makes the movement of the filter element 3 controllable, ensuring the precise configuration of the water pipe 32 in different positions and avoiding incorrect installation or separation of the filter element due to misoperation.

[0044] like Figure 7 and Figure 12 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the push-up portion 23 also includes a locking rib 233, which is disposed on the handle body 21. A clearance space 201 is provided between the locking rib 233 and the push-up rib 231. When the handle assembly 2 is in the first position, the lug 331 is located in the clearance space 201 and between the locking rib 233 and the push-up rib 231. During at least a part of the rotation of the handle assembly 2 from the second position to the first position, the locking rib 233 abuts against the lug 331. The clearance space 201 between the locking rib 233 and the push-up rib 231 provides the necessary gap, avoiding direct friction between the locking rib and the push-up rib and the lug 331. In this way, wear of components caused by friction due to operation or frequent rotation is avoided, extending the service life of the handle assembly 2 and related components of the filter element 3. Especially after long-term use, damage to components that may be caused by excessive friction is avoided.

[0045] like Figure 11 and Figure 12As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of push ribs 231 is two, and the two push ribs 231 are located on opposite sides of the handle body 21; the number of lugs 331 is two, and the two lugs 331 are located on opposite sides of the filter element body 31. By having two push ribs 231, located on opposite sides of the handle body 21, it is ensured that the force transmission is more uniform during operation, avoiding the deviation or instability that may be caused by excessive force concentration on one side. This symmetrical arrangement ensures the smoothness of operation, making the entire assembly more stable during rotation, avoiding unnecessary twisting or pressure concentration, thereby protecting the durability of each component.

[0046] like Figure 12 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the push-up part 23 includes a limiting plate 232, which is disposed on the handle body 21; the filter body 31 forms an inclined surface 332 on the side away from the water channel plate 1; the baffle part 33 includes the inclined surface 332; the handle body 21 is provided with a limiting notch 202; the limiting plate 232 is located on the inner wall of the limiting notch 202; the limiting plate 232 is adapted to the inclined surface 332; when the handle assembly 2 rotates relative to the water channel plate 1, it has at least a third position and a fourth position; when the handle assembly 2 is in the third position, the length of the water pipe 32 in the channel 101 is L3; when the handle assembly 2 is in the fourth position, the length of the water pipe 32 in the channel 101 is L4, where L4 is less than L3; when the handle assembly 2 is in the third position, the limiting plate 232 abuts against the inclined surface 332. Through the adaptation of the limiting plate 232 and the inclined surface 332, a clear physical stop position can be provided when the handle assembly 2 rotates to the third position. The interaction between the limiting plate and the inclined surface ensures the stability of the filter element body 31 within the water channel plate 1, preventing the filter element from shifting or loosening due to external forces or vibrations. This design ensures that the filter element remains in an accurate and predetermined position during operation, improving the stability and functional reliability of the device.

[0047] like Figure 11 and Figure 12As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the handle body 21 includes a toggle plate 211 and a locking plate 212. The toggle plate 211 is arc-shaped, and the rotating shaft 22 is disposed on the toggle plate 211 and located at both ends of the toggle plate 211. An obstacle space 201 adapted to the filter element body 31 is formed on the inner side of the toggle plate 211. The locking plate 212 is disposed on the toggle plate 211 and covers part of the obstacle space. The limiting plate 232 is connected to the toggle plate 211 and the locking plate 212 respectively. The toggle plate 211, being arc-shaped and having an obstacle space 201 adapted to the filter element body 31, locks the filter element body 31 by engaging and locking it. The locking plate 212, covering part of the obstacle space 201, mainly provides additional support. The locking plate 212, working together with the toggle plate 211, reinforces and ensures the stable installation of the filter element. This design effectively prevents the filter element from becoming loose or shifting after installation, ensuring the stability and sealing of the filter element during operation.

[0048] like Figure 12 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of limiting plates 232 is multiple, and the multiple limiting plates 232 are arranged at intervals. The increase in the number of limiting plates 232 disperses the pressure or friction force borne by each limiting plate, avoiding wear caused by excessive force on a single limiting plate. Distributing the load can reduce local wear, help improve the durability of the device, and extend the service life of the components.

[0049] In addition to the features of the above embodiments, this embodiment further includes a positioning part and a limiting part. One of the positioning part and the limiting part is disposed on the handle assembly 2, and the other is disposed on the filter element 3. The positioning part and the limiting part are adapted to each other. The positioning part and the limiting part effectively prevent unnecessary movement of the filter element 3 during operation. Through the adapted positioning and limiting action, the position of the filter element in the device is firmly fixed, so that the filter element will not loosen or shift during normal use. This not only enhances the stability of the filter element in the water system, but also avoids water leakage or performance degradation caused by improper filter element positioning.

[0050] like Figure 2 and Figure 12As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the positioning part is a protrusion, and the limiting part is a groove. The protrusion is disposed on the handle assembly 2, and the groove is located on the filter element 3. The protrusion can be engaged with the groove. The engaging design of the protrusion and the groove provides a physical locking mechanism, ensuring that the filter element 3 will not loosen or fall off due to external force or vibration during operation. By engaging with the groove, the protrusion can effectively lock the filter element, preventing it from accidentally shifting or falling off during equipment use. This stable connection method not only improves safety but also ensures stable operation of the equipment during long-term use, avoiding water leakage or incomplete filtration.

[0051] like Figure 13 As shown, in addition to the features of the above embodiments, this embodiment further defines: the water pipe 32 includes a pipe body 321 and a sealing ring 322. The pipe body is disposed on the filter element body 31. A first step 301 is formed on the outer wall of the pipe body 321, and a second step 102 is formed on the inner wall of the channel 101. The second step 102 is adapted to the first step 301, and the sealing ring 322 is located at the first step 301. The cooperation between the first step 301 and the second step 102 provides a robust connection mechanism. This step adaptation design ensures that the water pipe 32 can be stably positioned within the channel 101, avoiding loosening or misalignment due to external forces or vibrations. The step structure enhances the sealing performance through precise engagement, ensuring that water flow does not leak along the interface, thereby improving the sealing performance of the equipment and preventing leakage problems. Due to the step cooperation design, the connection between the water pipe and the channel has higher reliability and stability. During long-term use, the step structure can effectively mitigate wear or loosening problems caused by repeated loading and unloading, external forces, or vibrations. Therefore, stepped design helps improve the durability of equipment, extend its service life, and reduce maintenance needs caused by loose or leaking parts.

[0052] like Figure 12 and Figure 13As shown, in addition to the features of the above embodiments, this embodiment further defines: the pushing part 23 includes a pushing rib 231, a limiting plate 232, and a locking rib 233; the handle body 21 is provided with a limiting notch 202; clearance spaces 201 are provided on opposite sides of the limiting notch 202; the limiting plate 232 and the locking rib 233 are located on both sides of the clearance spaces 201; the blocking part 33 includes a lug 331 and an inclined surface 332; the lug 331 is provided on the filter body 31 and located on opposite sides of the filter body 31; the side of the filter body 31 away from the water channel plate 1 forms an inclined surface; the lug 331 is adapted to the clearance space 201; and the handle assembly... When the handle assembly 2 rotates relative to the water channel plate 1, it has at least a first position and a second position. When the handle assembly 2 is in the first position, the length of the water pipe 32 within the channel 101 is L1, and the push rib 231 is located between the rotating shaft 22 and the lug 331. When the handle assembly 2 is in the second position, the length of the water pipe 32 within the channel 101 is L2, where L2 is less than L1. When the handle assembly 2 rotates from the first position to the second position, the push rib 231 abuts against the lug 331. When the handle assembly 2 rotates from the second position to the first position, the locking rib 233 abuts against the lug 331. When the handle assembly 2 is in the second position, the limiting plate 232 abuts against the inclined surface 332. Through the cooperation of the push rib 231, the limiting plate 232, the locking rib 233, and the clearance space 201, the handle assembly 2 can rotate precisely and ensure reliable contact and locking with the filter body 31 in different positions. Specifically, when the handle assembly 2 rotates from the first position to the second position, the push rib 231 abuts against the lug 331, forming a physical engagement, thereby ensuring the stable position of the water pipe 32 within the channel 101. This design improves the connection stability between the filter element assembly and the water circuit board, preventing loosening or misalignment caused by vibration or other external factors. Through the contact between the push rib 231 and the lug 331, and the precise engagement of the locking rib 233, the handle assembly 2 can easily rotate between different positions and lock in the desired position. Operators can easily install, remove, and replace the filter element simply by rotating the handle assembly. This simplified operation reduces the complexity of manual adjustment, improves the user experience, and avoids leakage or damage caused by improper operation. The contact design between the limiting plate 232 and the inclined surface 332 ensures that the handle assembly 2 can accurately stop at a specific position during rotation. When the handle assembly rotates to the second position, the limiting plate 232 abuts against the inclined surface 332, ensuring the filter element is in the correct position and preventing misoperation due to improper operation. With this precise positioning mechanism, users can more easily and reliably install and replace filter cartridges.

[0053] Example 2

[0054] This embodiment discloses a water purification device, which includes the above-mentioned filter positioning assembly.

[0055] The second aspect of this application discloses a water purification device in which a filter cartridge positioning assembly is used. The pusher 23 and the baffle 33 work together to ensure the filter cartridge can smoothly separate from the water circuit board when the handle assembly 2 is rotated. This structure avoids the problems of loose filter cartridge fixation or damage that may occur in traditional disassembly methods. This design ensures that the filter cartridge is less likely to be accidentally damaged or unable to separate smoothly during disassembly.
