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

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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 showing the effect of the handle in one state in the filter assembly. Figure 3 This is a schematic diagram showing the handle of the filter assembly in another state. The filter assembly may include: filter element 100, water channel plate 200, water receiving channel 300, and handle 400.

[0035] In the filter element assembly, the filter element 100, the receiving channel 300, and the channel plate 200 are arranged sequentially along the target direction. 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 receiving channel 300 may be slidably connected to the channel hole 101 in the filter element 100 and the first channel hole 201 in the channel plate 200 along the target direction, respectively, and the receiving channel 300 may have a water passage 301 communicating with both the channel hole 101 and the first channel hole 201.

[0036] The handle portion 400 in the filter element assembly may have a movable connection end 401, which can be rotatably connected to the outer side of the receiving channel 300 and swing-connected to the side of the filter element 100.

[0037] The handle 400 can be configured to extend and retract the end of the water channel 300 that is connected to the first water channel hole 201 of the water channel plate 200 during the swinging process relative to the filter element 100.

[0038] In this embodiment, a receiving channel 300 is provided between the filter element 100 and the channel plate 200. The receiving 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 movable connecting end of the handle 400 rotates with the outer side of the receiving channel 300 and is oscillatingly connected to the side of the filter element 100. Thus, during the swinging of the handle 400 relative to the filter element 100 to the first state, the receiving channel 300 can be moved closer to the channel hole 101, causing the end of the receiving channel 300 connected to the first channel hole 201 to retract and separate from the first channel hole 201, thereby unlocking the filter element 100 from the channel plate 200. During the assembly of the filter element 100 and the water channel plate 200, as the handle 400 swings relative to the filter element 100 to the second state, it can drive the receiving water channel 300 to extend towards the first water channel hole 201 of the water channel plate 200, so that the end of the receiving water channel 300 connected to the first water channel hole 201 slides into the first water channel hole 201. For example, one of the first state and the second state can be the handle unfolded state, and the other can be the folded state.

[0039] Here, through the installation structure of the filter element assembly, the handle 400 can be swung while the filter element 100 does not rotate, greatly reducing rotational resistance and improving the customer experience. When it is necessary to disassemble the filter element 100, the handle 400 is swung to disengage the receiving channel 300, which cooperates with the filter element 100, from the channel plate 200. The filter element 100 can then be lifted out through the handle 400 for easy disassembly. The above filter element structure achieves disassembly and assembly through the ingenious cooperation between the handle 400, the filter element 100, and the receiving channel 300. The structure is simple and stable, with high disassembly and assembly efficiency, and has great market promotion value.

[0040] In summary, this application provides a filter element assembly, which may include: a filter element, a receiving channel, a channel plate, and a handle. Through the installation structure of the filter element assembly, the handle can be swung while the filter element does not rotate, greatly reducing rotational resistance and improving the customer experience. When the filter element needs to be disassembled, the handle is swung to disengage the receiving channel, which cooperates with the filter element, from the channel plate, and then the filter element is lifted out through the handle for easy disassembly. The above filter element structure achieves disassembly and assembly through the ingenious cooperation between the handle, the filter element, and the receiving channel. The structure is simple and stable, with high disassembly and assembly efficiency, and has significant market potential.

[0041] Optional, please refer to Figure 4 , Figure 4 This is an exploded structural diagram of another filter element assembly provided in this application embodiment. The movable connecting end 401 of the handle portion 400, facing the filter element 100, may have a sliding arc groove a1. The top edge of the filter element 100 may have a positioning pin a2, which can be located within the sliding arc groove a1 and slide in cooperation with it. The virtual center of the sliding arc groove a1 is eccentrically positioned between the movable connecting end 401 of the handle portion 400 and the rotation axis of the receiving water channel 300. Thus, during the swinging of the handle portion 400, the sliding arc groove a1 and the positioning pin a2, through their limiting action, allow the movable connecting end 401 of the handle portion 400 to rotate relative to the receiving water channel 300, thereby causing the receiving water channel 300 to slide along a target direction, and thus enabling the receiving water channel 300 to disengage from or engage with the first water channel hole 201 of the water channel plate 200.

[0042] In this embodiment, one of the movable connecting end 401 of the handle portion 400 and the outer surface of the receiving channel 300 may have a pivot b1, and the other of the movable connecting end 401 of the handle portion 400 and the outer surface of the receiving channel 300 may have a rotating mounting hole b2 that rotatably engages with the pivot b1. (Example provided.)

There can also be multiple receiving water channels 300, each corresponding to one of the number of water channel holes 101. Each receiving water channel 300 has two ends that can extend into its corresponding water channel hole 101 and first water channel hole 201, respectively. Here, the multiple receiving water channels 300 can be fixedly connected.

[0047] In this embodiment, the two ends of the receiving waterway 300 are respectively sealed to the inner wall of the waterway hole 101 and the inner wall of the first waterway hole 201 by annular seals.

[0048] For example, in one alternative implementation, such as Figure 4 As shown, the two ends of the receiving water channel 300 may each have a first annular groove 302. The filter element assembly includes a plurality of corresponding first annular seals 500 that are fastened in the plurality of first annular grooves 302. The plurality of first annular seals 500 are respectively used to abut against the inner wall of the water channel hole 101 and the inner wall of the first water channel hole 201.

[0049] In another alternative implementation, 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 inner wall of the first water channel hole 201 in the water channel plate 200 may have a third annular groove. The filter element structure includes: a second annular seal (not shown in the figure) fastened in the second annular groove and sleeved on one end of the receiving water channel 300, and a third annular seal fastened in the third annular groove and sleeved on the other end of the receiving water channel 300.
