The filter core 1 can also be an ultrafiltration filter core, a nanofiltration filter core, or a filter core composed of multiple filtering materials. Please refer to Figure 4 The filter core 1 has two clamping grooves 11 arranged oppositely on the filter core 1. For example, the filter core 1 can be configured in a cylindrical shape, and the two clamping grooves 11 are arranged oppositely along the radial direction of the filter core 1. The arrangement direction of the two clamping grooves 11 is the first direction, for example, Figure 5 and Figure 6 The direction indicated by R1 in the above formula is the first direction. The handle 2 is provided on the filter core 1 to facilitate the installation and removal of the filter core 1, and the material of the handle 2 can be a material with certain elasticity and hardness, for example, it can be plastic. The handle 2 comprises a gripping portion 21 and a connecting piece 22, the gripping portion 21 is used for the user to hold, and the gripping portion 21 can be configured as a space U-shaped as shown in Figure 1 and Figure 2 to make the installation and removal of the filter core 1 more convenient, the connecting piece 22 comprises a connecting rod 221 connected in the first direction and a limiting piece 222, the gripping portion 21 is connected with the connecting rod 221, for example, the two ends of the gripping portion 21 configured as a space U-shaped are respectively connected with the connecting rod 221, and the limiting piece 222 is arranged in the clamping groove 11, so that the handle 2 can not only rotate relative to the filter core 1 with the first direction as the rotation axis, but also can be limited by the limiting piece 222 and the clamping groove 11 to make the handle 2 not easy to separate from the filter core 1 along the first direction.

[0032] Exemplarily, the connecting rod 221 and the limiting piece 222 can be configured as one-piece, or can be configured as separately formed and then connected, to reduce the difficulty of injection molding demolding of the connecting piece 22.

[0033] Exemplarily, please refer to Figure 6 The limiting piece 222 can comprise a limiting body 2221 and a limiting buckle 2222 connected with each other, the limiting body 2221 is arranged in the clamping groove 11, the connecting rod 221 is a hollow structure, the limiting buckle 2222 can pass through the connecting rod 221 along the first direction, and one end of the limiting buckle 2222 away from the limiting body 2221 along the first direction can be clamped with the connecting rod 221, so that the limiting piece 222 is connected with the connecting rod 221, and then the handle 2 is not easy to separate from the filter core 1 in the first direction.

[0034] Please refer to Figures 2 to 4The slot wall of the clamping groove 11 away from the filter element 1 has a mounting cavity 12 and a mounting opening 13. The mounting cavity 12 and the mounting opening 13 are in communication. The arrangement direction of the mounting cavity 12 and the mounting opening 13 is a second direction. The second direction is transverse to the first direction. For example, Figure 4 The direction represented by R2 in the formula is the second direction. The connecting rod 221 can be installed into the mounting cavity 12 through the mounting opening 13, so that the limiting piece 222 is located in the clamping groove 11, and then the limiting piece 222 and the connecting rod 221 can be connected into the connecting piece 22 first, and then the connecting piece 22 is limited and matched with the clamping groove 11, or the connecting piece 22 is disassembled from the clamping groove 11 first, and then the connecting piece 22 is disassembled into the connecting rod 221 and the limiting piece 222, so that the handle 2 and the filter element 1 are more convenient to disassemble and assemble.

[0035] In the embodiment, the limiting piece 222 of the handle 2 is arranged in the clamping groove 11 of the filter element 1, and the limiting piece 222 is limited and matched with the clamping groove 11, so that the handle 2 is not easy to be separated from the filter element 1 along the first direction without affecting the rotation of the handle 2 relative to the filter element 1 with the first direction as the rotation axis, and then the filter element structure 10 can improve the success rate of assembly or disassembly even if there is a certain injection molding tolerance. It can be understood that the slot wall of the clamping groove 11 away from the filter element 1 is not limited to having the mounting opening 13. For example, the connecting rod 221 can be arranged in the slot wall of the clamping groove 11 away from the filter element 1 first, and then the connecting rod 221 and the limiting piece 222 are connected in the clamping groove 11.

[0036] In an embodiment, please refer to Figure 4 The radial dimension of the connecting rod 221 is less than or equal to the dimension of the mounting cavity 12, so that the rotation of the connecting rod 221 is more smooth, and then it is beneficial to improve the smoothness of the rotation of the handle 2 relative to the filter element 1. The radial dimension of the connecting rod 221 is greater than or equal to the dimension of the mounting opening 13, so that the connecting rod 221 can enter the mounting cavity 12 by relying on the elastic deformation of itself and the slot wall of the clamping groove 11, and then the connecting rod 221 is not easy to be separated from the mounting cavity 12 along the second direction, and then the handle 2 is not easy to be separated from the filter element 1 along the second direction, which is beneficial to improve the reliability of the connection of the handle 2 and the filter element 1.

[0037] In an embodiment, please refer to Figure 2 and Figure 5 The limiting piece 222 is configured as a disc shape.

[0038] In an embodiment, please refer to Figure 2 andFigure 5 The radial dimension of the limiting member 222 is less than or equal to the dimension of the clamping groove 11, which on the one hand enables the limiting member 222 to enter the clamping groove 11 more smoothly in the second direction, and on the other hand enables the limiting member 222 to rotate more smoothly in the clamping groove 11, thereby facilitating the improvement of the flow field degree of the rotation of the handle 2 relative to the filter element 1.

[0039] The second aspect of the embodiment of the present application provides a water purifier 100, which comprises the filter element structure 10 and a waterway assembly 20. The waterway assembly 20 is connected with the filter element structure 10. For example, the waterway assembly 20 can be connected with the filter element structure 10 in the third direction, so that the filter element structure 10 can enter and exit water through the waterway assembly 20, and then the liquid in the waterway assembly 20 can be filtered by the filter element structure 10. The third direction can be arranged transversely to the first direction, for example, Figure 1 The direction represented by R3 in the formula is the third direction.

[0040] In an embodiment, referring to Figures 2 to 4 The waterway assembly 20 has an assembly groove 201, and the handle 2 comprises an assembly strip 23. When the handle 2 rotates relative to the filter element 1 with the first direction as the rotation axis, the assembly strip 23 can be located in the assembly groove 201, so that the filter element 1 can be connected with the waterway assembly 20 more reliably.

[0041] For example, when the handle 2 is located at the position shown in Figure 1 , the assembly strip 23 of the handle 2 is located in the assembly groove 201 of the waterway assembly 20, so that the filter element 1 can be connected with the waterway assembly 20 through the handle 2. When the handle 2 rotates clockwise by 90°, the assembly strip 23 can be separated from the assembly groove 201, so that the filter element 1 can be detached from the waterway assembly 20.

[0042] In an embodiment, referring to Figure 2 The filter element 1 has a limiting protrusion 14, and the limiting protrusion 14 is located on the outer periphery of the filter element 1. The gripping portion 21 has a limiting recess 211. When the assembly strip 23 is located in the assembly groove 201, for example Figure 1 , the filter element 1 is installed in place with the waterway assembly 20, and the limiting protrusion 14 can be located in the limiting recess 211. In the case that the filter element 1 and the waterway assembly 20 are installed in place, the limiting protrusion 14 located in the limiting recess 211 can reduce the possibility of the rotation of the handle 2 relative to the filter element 1 under external interference, thereby reducing the possibility of installation failure of the filter element 1 and the waterway assembly 20, and facilitating the improvement of the installation stability of the water purifier 100.

[0043] The above is the preferred embodiment of the present application, it should be pointed out that, for those skilled in the ordinary in the art, without departing from the principles described in the present application, can be made several improvements and refinements, these improvements and refinements should also be considered as the scope of protection of the present application.
