[0002] Currently, the filter cartridge fixing structure of countertop water purifiers and under-sink water purifiers is basically achieved by rotating the filter cartridge for disassembly and assembly. Due to the water pressure and the expansion of the sealing ring, the rotational force is relatively large. When the filter cartridge expires, consumers need to replace it themselves. Some consumers are female users, so disassembling and assembling the filter cartridge is quite difficult, resulting in a poor user experience.

[0003] Therefore, there is an urgent need to provide a filter assembly that is easy for users to disassemble. Utility Model Content

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is an exploded structural diagram of a filter element assembly provided in an embodiment of this application. Figure 2 This is a schematic diagram illustrating the effect of a filter element assembly in an assembled and used state, as provided in an embodiment of this application. Figure 3 This is a schematic diagram illustrating the effect of a filter element assembly in a disengaged state according to an embodiment of this application. The filter element assembly may include: a filter element 100, a water channel plate 200, a transition water channel 300, and a handle 400.

[0038] In the filter assembly, the filter element 100, transition channel 300, and channel plate 200 are arranged sequentially along a first direction f. The top of the filter element 100 may have a channel hole 101, and the channel plate 200 may have a first channel hole 201 communicating with the channel hole 101 in the filter element 100. The two ends of the transition channel 300 may be slidably connected along the first direction f to the channel hole 101 in the filter element 100 and the first channel hole 201 in the channel plate 200, respectively, and the transition channel 300 may have a water passage 301 communicating with both the channel hole 101 in the filter element 100 and the first channel hole 201 in the channel plate 200. Here, the number of channel holes 101 in the filter element 100 and the number of first channel holes 201 in the channel plate 200 can both be multiple and correspond one-to-one. The number of transition channels 300 can be multiple and can correspond one-to-one with the water channel holes in the filter element 100, and multiple transition channels 300 can be fixedly connected.

[0039] The handle 400 in the filter element assembly is drivenly connected to both the water channel plate 200 and the transition water channel 300. The handle 400 can be configured to extend or retract the end of the transition water channel 300 connected to the water channel hole 101 of the filter element 100 during the swinging motion relative to the water channel plate 200.

[0040] In this embodiment, the filter element 100, transition channel 300, and channel plate 200 in the filter element assembly are arranged sequentially along a first direction. The transition channel 300 is slidably connected to the channel hole 101 of the filter element 100 and the first channel hole 201 of the channel plate 200. Furthermore, the handle 400 is driveably connected to both the channel plate and the transition channel. Thus, when the handle 400 swings relative to the channel plate to a first state, it can drive the transition channel 300 to move closer to the first channel hole, causing the end of the transition channel 300 connected to the channel hole of the filter element to retract and separate from the channel hole, thereby unlocking the filter element 100 from the channel plate 200. During the assembly of the filter element 100 and the channel plate 200, when the handle 400 swings relative to the channel plate to a second state, it can drive the transition channel 300 to extend closer to the channel hole 201 of the filter element, causing the end of the transition channel 300 connected to the channel hole to slide into the channel hole 201. For example, one of the first and second states can be the handle unfolded state, and the other can be the folded state.

[0041] Here, the filter element assembly's installation structure allows the handle 400 to swing while the filter element 100 remains stationary, significantly reducing rotational resistance and improving customer experience. When filter element 100 needs to be disassembled, swinging the handle 400 disengages the transition channel 300, which cooperates with filter element 100, from the filter element, allowing filter element 100 to be easily removed from the water purification equipment. The above filter element structure achieves disassembly and assembly through the ingenious cooperation between the handle 400, filter element 100, and transition channel 300. The structure is simple, stable, and highly efficient, possessing significant market potential. Furthermore, after the transition channel 300 separates from filter element 100, both the handle 400 and the transition channel 300 are mounted on the channel plate 200. Replacing filter element 100 only requires disassembling filter element 100, allowing the handle 400 and transition channel 300 to be reused, thus reducing the cost of the filter element assembly.

[0042] In summary, this application provides a filter cartridge assembly, which may include: a filter cartridge, a water channel plate, a transition water channel, and a handle. Through the installation structure of the filter cartridge assembly, the handle can be swung while the filter cartridge does not rotate, greatly reducing rotational resistance and improving the customer experience. When the filter cartridge needs to be disassembled, the handle is swung to disengage the transition water channel that cooperates with the filter cartridge, allowing the filter cartridge to be removed from the water purification equipment, facilitating disassembly. The above filter cartridge structure achieves disassembly and assembly through the ingenious cooperation between the handle, filter cartridge, and transition water channel. The structure is simple and stable, with high disassembly and assembly efficiency, and has significant market potential. Furthermore, after the transition water channel separates from the filter cartridge, both the handle and the transition water channel are mounted on the water channel plate. When replacing the filter cartridge, only the filter cartridge needs to be disassembled, allowing the handle and transition water channel to be reused, reducing the cost of the filter cartridge assembly.

[0043] Optional, please refer to Figure 4 and Figure 5 , Figure 4 This is an exploded view of another filter element assembly provided in an embodiment of this application. Figure 5 yes Figure 4 The diagram shows the effect of the filter element assembly in use. The handle 400 may have a drive end 401 at its end, which can be rotatably connected to the side of the transition channel 300 and oscillatingly connected to the side of the channel plate 200. Specifically, the handle 400 can be configured such that, under external force, the drive end 401 oscillates relative to the channel plate 200, causing the end of the transition channel 300 connected to the channel hole 101 of the filter element 100 to extend or retract. Thus, by rotatably connecting the drive end 401 of the handle 400 to the side of the transition channel 300 and oscillatingly connecting it to the side of the channel plate 200, the extension and retraction of the end of the transition channel 300 connected to the channel hole 101 of the filter element 100 through the drive end 401 during the swinging of the handle 400 relative to the channel plate 200 achieves the connection and disconnection of the transition channel 300 from the filter element 100.

[0044] In this application, as Figure 4 and Figure 5 As shown, the drive end 401 of the handle 400 may have a swing groove c1 on its side facing the waterway plate 200, and the side of the waterway plate 200 may have a sliding positioning pin c2, which can slide in engagement with the swing groove c1. The virtual center of the swing groove c1 in the handle 400 is eccentrically positioned to the rotation axis of the drive end 401 and the transition waterway 300. In this configuration, the drive end 401 of the handle 400 is rotatably connected to the transition waterway 300. During the swinging motion of the handle 400 relative to the waterway plate 200, the limiting engagement of the swing groove c1 and the sliding positioning pin c2 synchronously drives the transition waterway 300 to slide along the first direction f.

[0045] Optional, such as Figure 4 and Figure 5 As shown, one of the drive end 401 of the handle 400 facing the side of the transition channel 300 and the side of the transition channel 300 may have a rotating shaft z1, and the other of the drive end 401 of the handle 400 facing the side of the transition channel 300 and the side of the transition channel may have a rotating hole z2 that rotatably engages with the rotating shaft z1.

[0046] For example, the drive end 401 of the handle 400 may have a rotating shaft z1 on the side facing the transition channel 300, and the side of the transition channel 300 may have a rotating hole z2 that mates with the rotating shaft z1. Alternatively, the drive end 401 of the handle 400 may have a rotating hole z2 on the side facing the transition channel 300, and the side of the transition channel 300 may have a rotating shaft z1 that mates with the rotating hole z2.

[0047] In the embodiments of this application, such as Figure 4 As shown, the handle 400 may include a grip portion 410 and two opposing drive arms 420. The grip portion 410 may be fixedly connected to one end of the two drive arms 420, and the other end of each drive arm 420 may have a drive end 401. In this way, the user can grip the grip portion 410 to drive the drive arms 420 to swing, thereby driving the transition channel 300.

[0048] Optionally, the two ends of the transition channel 300 can be slidably sealed to the channel holes 101 in the filter element 100 and the first channel hole 201 in the channel plate 200 via annular seals. In this way, while the transition channel 300 is slidably connected to the channel holes 101 in the filter element 100 and the first channel hole 201 in the channel plate 200, it can also be sealed by annular seals to ensure the water flow sealing of the filter assembly.

[0049] For example, such as Figure 4 As shown, the outer side of the end of the transition channel 300 connected to the channel hole 101 of the filter element 100 may have a first annular groove b1, and the annular seal 500 may be fixed in the first annular groove b1 and slide in fit with the inner wall of the channel hole 101.

[0050] Alternatively, the inner wall of the water channel hole 101 in the filter element 100 may have a second annular groove (not shown in the figure), and the annular seal may be fixed in the second annular groove and sleeved on the end of the transition water channel connected to the water channel hole.

[0051] Here, the outer side of the end of the transition channel 300 that connects to the first channel hole 201 of the channel plate 200 may have a third annular groove b2, and the annular seal 500 may be fixed in the third annular groove b2 and slide in cooperation with the inner wall of the first channel hole 201 of the channel plate 200.

[0052] Alternatively, the inner wall of the first waterway hole 201 in the waterway plate 200 may have a fourth annular groove (not shown in the figure), and the annular seal 500 may be fixed in the fourth annular groove and sleeved on the end of the transition waterway that is connected to the first waterway hole.

[0053] In summary, this application provides a filter cartridge assembly, which may include: a filter cartridge, a water channel plate, a transition water channel, and a handle. Through the installation structure of the filter cartridge assembly, the handle can be swung while the filter cartridge does not rotate, greatly reducing rotational resistance and improving the customer experience. When the filter cartridge needs to be disassembled, the handle is swung to disengage the transition water channel that cooperates with the filter cartridge, allowing the filter cartridge to be removed from the water purification equipment, facilitating disassembly. The above filter cartridge structure achieves disassembly and assembly through the ingenious cooperation between the handle, filter cartridge, and transition water channel. The structure is simple and stable, with high disassembly and assembly efficiency, and has significant market potential. Furthermore, after the transition water channel separates from the filter cartridge, both the handle and the transition water channel are mounted on the water channel plate. When replacing the filter cartridge, only the filter cartridge needs to be disassembled, allowing the handle and transition water channel to be reused, reducing the cost of the filter cartridge assembly.
