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

[0035] 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.

[0036] 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.

[0037] 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.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is an exploded structural diagram of a filter element structure provided in an embodiment of this application. Figure 2 This is a structural diagram showing the handle component in one state within the filter element structure. Figure 3 This is a schematic diagram of the filter element structure with the handle in another state. The filter element structure may include: filter element 100, water channel plate 200, central water channel 300, and handle 400.

[0039] The top of the filter element 100 in the filter element structure has a first water channel hole 101 extending along a first direction f.

[0040] The water channel plate 200 in the filter element structure can be distributed on one side of the opening of the first water channel hole 101 and can have a second water channel hole 201 that communicates with the first water channel hole 101.

[0041] The central water channel 300 in the filter element structure is slidably connected to the filter element 100 and the water channel plate 200 along the first direction f, and can have a water passage 301 that connects the first water channel hole 101 in the filter element 100 and the second water channel hole 201 in the water channel plate 200.

[0042] One end of the handle 400 in the filter element structure can be rotatably connected to the side of the filter element 100, and the handle 400 is oscillatingly connected to the central water channel 300. The handle 400 can be configured such that, during rotation relative to the filter element 100, it drives the two ends of the central water channel 300 to slide relative to the first water channel hole 101 in the filter element 100 and the second water channel hole 201 in the water channel plate 200, respectively.

[0043] In this embodiment, a central water channel 300 is provided between the filter element 100 and the water channel plate 200. The central water channel 300 is slidably connected to both the first water channel hole 101 of the filter element 100 and the second water channel hole 201 of the water channel plate 200. Furthermore, a handle 400 is provided with one end rotating relative to the side of the filter element, and the handle 400 is oscillatingly connected to the central water channel 300. Thus, during the rotation of the handle 400 relative to the filter element 100 to the first state, the central water channel 300 can be moved closer to the first water channel hole 101, causing the end of the central water channel 300 connected to the second water channel hole 201 to separate from the second water channel hole 201, thereby unlocking the filter element 100 from the water channel plate 200. During the assembly of the filter element 100 and the water channel plate 20, as the handle 400 rotates relative to the filter element 100 to the second state, it can drive the central water channel 300 to move towards the second water channel hole 201 of the water channel plate 200, so that the end of the central water channel 300 connected to the second water channel hole 201 slides into the second 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.

[0044] Here, the installation structure of filter element 100 allows the handle 400 to rotate while the filter element 100 remains stationary, significantly reducing rotational resistance and improving customer experience. When disassembling filter element 100, rotating the handle 400 disengages the central water channel 300, which engages with the filter element 100, from the water channel plate 200. The filter element 100 can then be lifted using the handle 400 for easy removal. This filter element structure achieves assembly and disassembly through the ingenious cooperation between the handle 400, the filter element 100, and the central water channel 300. The structure is simple, stable, and highly efficient, possessing significant market potential.

[0045] In summary, this application provides a filter element structure that may include: a filter element, a channel plate, a central channel, and a handle. Through the filter element's mounting structure, the handle can be rotated while the filter element remains stationary, significantly reducing rotational resistance and improving the customer experience. When the filter element needs to be disassembled, the handle is rotated to disengage the central channel, which engages with the filter element, from the channel plate, and then the filter element is lifted out through the handle for easy removal. The above filter element structure achieves assembly and disassembly through the ingenious cooperation between the handle, the filter element, and the central channel. The structure is simple and stable, with high assembly and disassembly efficiency, and possesses significant market potential.

[0046] For example, such as Figure 2 and Figure 3As shown, the number of first water channel holes 101 in the filter element 100 and the number of second water channel holes 201 in the water channel plate 200 can both be multiple and correspond one-to-one. The number of central water channels 300 can also be multiple and slide in a one-to-one correspondence with the first water channel holes 101 and the second water channel holes 201. Multiple central water channels 300 can be fixedly connected.

[0047] Optional, please refer to Figure 4 , Figure 4 This is an exploded view of another filter element structure provided in an embodiment of this application. The handle 400 may have a swing arm 410, one end of which may have a rotating hole k1. The top edge of the filter element 100 may have a rotating shaft k2 rotatably connected to the rotating hole k1. Thus, the rotational connection between the swing arm 410 in the handle 400 and the top edge of the filter element 100 is achieved through the cooperation of the rotating hole k1 and the rotating shaft k2. For example, the filter element 100 may include: a filter element body 110 and a top cover 120 connected to each other. The top cover 120 may be provided with a first water channel hole 101. Additionally, the rotating shaft k2 may be located on the edge of the top cover 120.

[0048] For example, the handle 400 may include two opposing swing arms 410 and a grip portion 420 fixedly connected to the other end of the two swing arms 410. In this way, the user can easily operate the handle 400 by holding the grip portion 420 to switch it between a first state and a second state.

[0049] In other possible implementations, the handle 400 may have a swing arm 410, one end of which may have a rotating shaft k2, and the top edge portion of the filter element 100 may have a rotating hole k1 that is rotatably connected to the rotating shaft k2.

[0050] In this embodiment, the side of the swing arm 410 in the handle 400 facing the central water channel 300 may have a sliding groove c1 distributed along the extending direction of the handle 400; the outer surface of the central water channel 300 may have a positioning shaft c2 that slides with the sliding groove c1. Thus, during the rotation of the end of the swing arm 410 of the handle 400 around the filter element 100, due to the limiting effect of the sliding groove c1 on the swing arm 410 and the positioning shaft c2 on the central water channel 300, the central water channel 300 can be driven to slide along the first direction f during the swinging of the handle 400, thereby achieving assembly and disassembly from the water channel plate 200. Here, the shape of the sliding groove c1 in the swing arm 410 of the handle 400 may be arc-shaped. For example, the convex surface of the arc-shaped sliding groove c1 faces the water channel plate 200 and the concave surface faces the filter element 100. When the handle 400 swings in a direction away from the water channel plate 200, it causes the central water channel 300 to separate from the second water channel hole 201 of the water channel plate 200.

[0051] The two ends of the central water channel 300 can be slidably and sealingly connected to the first water channel hole 101 in the filter element 100 and the second water channel hole 201 in the water channel plate 200, respectively. For example... Figure 4 As shown, in one optional implementation, the two ends of the central water channel 300 may each have a first annular groove 302, and the filter element structure includes: a plurality of corresponding first annular seals 500 fastened in the plurality of first annular grooves 302, and the plurality of first annular seals 500 are respectively used to abut against the inner sidewall of the first water channel hole 101 and the inner sidewall of the second water channel hole 201.

[0052] In another alternative implementation, the inner wall of the first 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 second 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 fastened in the second annular groove and sleeved on one end of the central water channel 300, and a third annular seal fastened in the third annular groove and sleeved on the other end of the central water channel 300.

[0053] In summary, this application provides a filter element structure that may include: a filter element, a channel plate, a central channel, and a handle. Through the filter element's mounting structure, the handle can be rotated while the filter element remains stationary, significantly reducing rotational resistance and improving the customer experience. When the filter element needs to be disassembled, the handle is rotated to disengage the central channel, which engages with the filter element, from the channel plate, and then the filter element is lifted out through the handle for easy removal. The above filter element structure achieves assembly and disassembly through the ingenious cooperation between the handle, the filter element, and the central channel. The structure is simple and stable, with high assembly and disassembly efficiency, and possesses significant market potential.

[0054] This application also provides a water purifier; please refer to [link / reference]. Figure 5 , Figure 5 This is a partial structural diagram of a water purifier provided in an embodiment of this application. The water purifier may include: a support 001 and a filter element structure, the filter element structure being disposed on the support 001.

[0055] Optional, please refer to Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the installation of a filter element structure and bracket provided in an embodiment of this application. Figure 7This is a schematic diagram illustrating the disassembly effect of the filter element structure and support. The support 001 may have a receiving cavity q and an installation port q1 located on the top of the support 001 and communicating with the receiving cavity q. The filter element 100 can be installed into the receiving cavity q through the installation port q1, and the water channel plate 200 can be installed on the top of the support 001 adjacent to the installation port q1. Thus, after the handle 400 drives the central water channel 300 to disengage from the second water channel hole 201 in the water channel plate 200, the filter element 100 can be removed from the receiving cavity q of the support 001 through the handle 400. When assembling the filter element 100, the filter element 100 is installed into the receiving cavity q of the support 001 through the installation port q1, and the handle 400 drives the central water channel 300 to engage with the second water channel hole 201 of the water channel plate 200.
