[0043] Water purification products are water purifiers, which are water treatment equipment that deeply filters and purifies water according to the requirements of water use. Water purifiers can effectively filter out rust, sand, colloids in water, and absorb residual chlorine, odor, discoloration, pesticides and other chemical agents in water. They can effectively remove bacteria, germs, toxins, heavy metals and other impurities in water. They are widely used in both civil and commercial applications.

[0044] In the relevant technical field, the rotating card core replacement method is often used. The filter element needs to rotate as a whole, and a corresponding rotating mechanism needs to be set on the waterway plate. The rotation of the filter element drives the rotation of the rotating mechanism of the waterway plate. This leads to a complex structure of the waterway plate and high cost. In addition, the assembly of the cover and the core is complicated, which is not conducive to enterprise production.

[0045] The utility model provides a filter element component and a water purification device.

[0046] In the embodiment of the present utility model, Figures 1 to 3 As shown, the filter element assembly 100 includes a filter element body 110 and an end cover body 120, one end of the filter element body 110 is provided with a plug-in column 111 for plugging with the waterway plate, and the other end is provided with a rotating connection portion 112 protruding from the end surface; the end cover body 120 has a first mounting surface 121 and a second mounting surface 122 arranged opposite to each other, the first mounting surface 121 is covered on the end of the filter element body 110 having the rotating connection portion 112, and a clamping hole 123 corresponding to the rotating connection portion 112 is provided on the end cover body 120, the clamping hole 123 passes through the first mounting surface 121 and the second mounting surface 122, and part of the rotating connection portion 112 extends out of the second mounting surface 122 from the clamping hole 123 to connect the end cover body 120 to the filter element body 110 in the axial direction.

[0047] The filter element body 110 is the core component of the filter element assembly 100, and is used to filter impurities in the water flow. A plurality of plug-in posts 111 are provided on one end of the filter element body 110 to be plugged into the waterway plate, wherein the plug-in posts 111 are provided with interfaces to connect the filter element body 110 and the waterway plate. It should be noted that the interfaces may include a water inlet, a water outlet and a wastewater outlet to connect the various flow paths in the filter element body 110 with the waterway plate, and the rotating connection part 112 at the other end is used to connect the end cover body 120 to achieve a rotating connection.

[0048] The end cap body 120 is rotatably connected to one end of the filter element body 110 to cooperate with the housing 200 or the support to fix the filter element body 110. The end cap body 120 has a first mounting surface 121 and a second mounting surface 122 that are arranged opposite to each other. The first mounting surface 121 covers the end of the filter element body 110. The function of the first mounting surface 121 is to improve the fit with the filter element body 110, thereby improving the connection strength between the end cap body 120 and the filter element body 110. At the same time, it can also protect the filter element body 110 and prevent dust, debris, etc. from contaminating the filter element. The second mounting surface 122 is arranged opposite to the first mounting surface 121, and a clamping hole 123 corresponding to the rotating connection part 112 is provided. When the end cap body 120 is combined with the rotating connection part 112 of the filter element body 110 through the clamping hole 123, the end cap body 120 and the filter element body 110 are axially limited. The clamping hole 123 on the end cover body 120 is a key part for connecting the filter element body 110 and the end cover body 120. The clamping hole 123 penetrates the first mounting surface 121 and the second mounting surface 122, and matches the rotating connection part 112 of the filter element body 110. By extending the rotating connection part 112 out of the second mounting surface 122, the end cover body 120 can be connected to the filter element body 110 in an axial limited manner through the clamping hole 123, thereby ensuring the stability and reliability of the filter element assembly 100.

[0049] The present application realizes the relative rotation between the filter element body 110 and the end cover body 120 by the cooperation between the rotating connection part 112 of the filter element body 110 and the clamping hole 123 of the end cover body 120. The end cover body 120 is allowed to rotate within a certain range to adapt to different installation and use environments. At the same time, part of the rotating connection part 112 extends out of the second mounting surface 122 from the clamping hole 123 to axially limit the end cover body 120 and ensure the stable connection between the filter element body 110 and the end cover body 120. The present application simplifies the assembly structure and improves the assembly efficiency by the cooperation between the rotating connection part 112 and the clamping hole 123. At the same time, since the filter element body 110 and the end cover body 120 can rotate relative to each other, the installation process of the filter element body 110 is simplified. During the installation process, the user only needs to insert the filter element body 110 into the waterway plate, and then the end cover body 120 is engaged with the housing 200 or the support by rotation, so that the axial position of the filter element body 110 can be fixed. In this way, the difficulty of installation is reduced and the installation efficiency is further improved.

[0050] Reference Figure 2 , Figure 3 and Figure 6According to an embodiment of the utility model, the rotating connection part 112 includes a connecting column 112a, one end of the connecting column 112a is connected to the filter element body 110, and a plurality of limiting bosses 112b are symmetrically arranged around the other end. The limiting bosses 112b, the connecting column 112a and the filter element body 110 are enclosed together to form a limiting groove 112d, and the clamping hole 123 is clamped with the limiting groove 112d. In this embodiment, the structure of the connecting column 112a and the limiting boss 112b enables the rotating connection part 112 to match the clamping hole 123 of the end cover body 120. When the limiting boss 112b of the end cover body 120 rotates and aligns with the rotating connection portion 112 of the filter element body 110, the combination between the limiting boss 112b and the clamping hole 123 will limit the axial movement of the end cover body 120 relative to the filter element body 110, thereby realizing the rotational connection of the end cover body 120 relative to the filter element body 110. The structure is simple and can simplify the assembly structure between the end cover body 120 and the filter element body 110.

[0051] Reference Figure 3 and Figure 6 According to an embodiment of the utility model, the limiting boss 112b is provided with an arcuate guide bevel 112c at one end away from the filter element body 110, and the arcuate guide bevel 112c is gradually arranged close to the axis in the direction from the filter element body 110 toward the end cover body 120. In this embodiment, the arcuate guide bevel 112c plays a role of guiding and bevel guiding during the installation and disassembly process of the filter element assembly 100. When the end cover body 120 rotates and aligns with the rotating connection part 112 of the filter element body 110, the clamping hole 123 on the end cover body 120 will be combined with the limiting boss 112b on the filter element body 110. By providing the arcuate guide bevel 112c on the limiting boss 112b, the docking of the end cover body 120 and the filter element body 110 can be made smoother.

[0052] Specifically, when the end cap body 120 rotates and approaches the filter element body 110, the locking hole 123 on the end cap body 120 contacts the arc-shaped guide slope 112c of the limiting boss 112b. Due to the existence of the arc-shaped guide slope 112c, the end cap body 120 is guided during the rotation process and is guided to gradually approach the axis of the filter element body 110. In this way, the docking process between the end cap body 120 and the filter element body 110 is smoother, avoiding damage caused by inaccurate docking, and improving installation efficiency.

[0053] Reference Figures 3 to 8According to an embodiment of the present utility model, the clamping hole 123 includes a column through-through portion 123a and a plurality of boss through-through portions 123b, the plurality of boss through-through portions 123b are arranged along the circumference of the column through-through portion 123a, and the boss through-through portion 123b is connected to the column through-through portion 123a, the column through-through portion 123a is arranged corresponding to the connecting column 112a, and the boss through-through portion 123b is arranged corresponding to the limiting boss 112b. It can be understood that the connecting column 112a is inserted into the clamping hole 123 through the column through-through portion 123a, and the limiting boss 112b is inserted into the clamping hole 123 through the boss through-through portion 123b. In this way, the connecting column 112a and the limiting boss 112b can pass through the clamping hole 123 at the same time, and after the limiting boss 112b completely passes through the clamping hole 123, the clamping hole 123 is clamped with the limiting groove 112d, limiting the movement of the filter element assembly 100 in the axial direction. In this way, the filter element assembly 100 can achieve reliable connection and limitation, ensuring the stability and safety of the filter element assembly 100 during use.

[0054] Reference Figure 5 and Fig. 9 According to an embodiment of the utility model, the filter element assembly 100 further includes a decorative member 130, the second mounting surface 122 is recessed toward one side of the filter element body 110 to form a mounting groove 122a, the clamping hole 123 is arranged at the bottom of the mounting groove 122a, the decorative member 130 covers the notch arranged at the mounting groove 122a, the decorative member 130 is provided with a limiting protrusion 132 protruding at the position corresponding to the boss through-through portion 123b, and the limiting protrusion 132 is plugged and matched with the boss through-through portion 123b. It can be understood that the decorative member 130 is connected to the end cover body 120 through the mounting groove 122a of the second mounting surface 122. The clamping hole 123 is arranged at the bottom of the mounting groove 122a, so that the docking between the filter element body 110 and the end cover body 120 can be facilitated, and the decorative member 130 covers the notch of the mounting groove 122a to improve the aesthetics. At the same time, a limiting protrusion 132 for blocking the protrusion through-through portion is protruded from the side of the decorative member 130 opposite to the groove bottom. During installation, the connecting column 112a of the rotating connecting portion 112 and the clamping hole 123 absorbed as the boss are passed through the first mounting surface 121. When the clamping hole 123 passes through the limiting groove 112d, the end cover body 120 is rotated to make the limiting boss 112b misaligned with the boss through-through portion 123b, and then the limiting protrusion 132 on the decorative member 130 is aligned and plugged with the boss through-through portion 123b to limit and fix the limiting boss 112b and the boss through-through portion 123b.

[0055] Reference Figure 4 and Figure 5According to an embodiment of the utility model, the rotatable angle of the end cap body 120 relative to the filter element body 110 is greater than or equal to 80° and less than or equal to 120°. It can be understood that the embodiment can control the size of the rotatable angle of the end cap body 120 relative to the filter element body 110 by setting the size and number of the central angles occupied by the boss through-through portion 123b, the limiting boss 112b and the limiting protrusion 132. After limiting the rotation range, the rotation angle between the end cap body 120 and the filter element body 110 can be more accurately controlled to avoid unnecessary problems caused by rotation beyond the range, such as structural damage. The specific rotation angle can be set as needed and is not specifically limited here.

[0056] Optionally, the rotatable angle of the end cap body 120 relative to the filter element body 110 can be 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 89°, 90°, 91°, 92°, 93°, 94°, 95°, 96°, 97°, 98°, 99°, 100°, 101°, 102°, 103°, 104°, 105°, 106° , 107°, 108°, 109°, 110°, 111°, 112°, 113°, 114°, 115°, 116°, 117°, 118°, 119°, 120°, 121°, 122°, 123°, 124°, 125°, 126°, 127°, 128°, 129° or 130°, etc., can be set according to actual needs and are not specifically limited here.

[0057] Reference Figure 8 According to an embodiment of the present invention, the outer periphery of the clamping hole 123 on one side of the installation groove 122a is inclined to form an arc-shaped guide surface 122b. It can be understood that the arc-shaped guide surface 122b is provided on the outer periphery of the clamping hole 123 on one side of the installation groove 122a, so that the limiting protrusion 132 can be more easily inserted into the boss through-hole 123b of the clamping hole 123 when the filter element assembly 100 is assembled. This simplifies the assembly process and saves time and labor.

[0058] According to an embodiment of the utility model, a buckle 122c is provided on the side wall of the installation groove 122a, and an undercut 131 is provided at the position of the decorative member 130 corresponding to the buckle 122c. The decorative member 130 is fixed to the notch of the installation groove 122a by the buckle connection between the buckle 122c and the undercut 131. It can be understood that the buckle 122c is a structure protruding on the two side walls of the installation groove 122a, and can also be a buckle. The buckle 122c is used to provide a fixed position for the decorative member 130. The undercut 131 is provided at the corresponding buckle 122c on the outer wall of the decorative member 130, which can be a groove or a protruding structure without special limitation. In this embodiment, the undercut 131 is matched with the buckle 122c to realize the clamping and fixing of the decorative member 130. When the decorative member 130 is inserted into the installation groove 122a, the undercut 131 and the buckle 122c are mutually clamped, so that the decoration is firmly fixed at the notch of the installation groove 122a. Thus, through the matching design of the buckle 122c and the undercut 131, the decorative element 130 can be safely and firmly fixed on the mounting groove 122a, so as to ensure that the decorative element 130 is not easy to loosen or fall off, and provide reliable connectivity and stability.
