Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a filter element. Background Technology

[0002] In recent years, with increasing environmental awareness, more and more filters on the market have adopted replaceable filter cartridge designs. These environmentally friendly filter cartridges only require replacement of the internal filter components during maintenance, eliminating the need to discard the entire filter housing. This reduces the environmental impact of waste and lowers maintenance costs for users. However, as replaceable filter cartridge designs become more widespread, the shortcomings of existing filter handle designs are becoming increasingly apparent. Most existing filter handles are fixed, requiring complex tools or manual adjustment during installation, resulting in time-consuming operations and a poor user experience. Therefore, there is an urgent need to design a filter cartridge with a convenient handle for installation. Utility Model Content

Figure 6 This is a schematic structural diagram of the second mounting structure 12 according to an embodiment of the present invention. Figure 7 This is a schematic structural diagram of the handle 20 according to an embodiment of the present invention. Figure 8 yes Figure 7 A schematic enlarged view of part A in the middle. Figure 9 This is a schematic structural diagram of a filter element 100 according to an embodiment of the present invention. Figures 1 to 9 As shown, in a specific embodiment, the filter element 100 includes an upper cover 10 and a handle 20. The upper cover 10 has a body 11, a first mounting structure 14, and a second mounting structure 12. The first mounting structure 14 and the second mounting structure 12 are arranged opposite to each other on the top of the body 11. The first mounting structure 14 has a first mounting hole 141, and the second mounting structure 12 has a second mounting hole 122 and a guide groove 121. The guide groove 121 has an opening 123 and a tail end, and the second mounting hole 122 is located at the tail end. The handle 20 has a carrying part 22 and two claws 21. The carrying part 22 is arc-shaped, and the two claws 21 are connected to both ends of the carrying part 22. One claw 21 directly enters the first mounting hole 141, and the other claw 21 slides into the guide groove 121 from the opening 123 and enters the second mounting hole 122 from the tail end along the guide groove 121. When installing the handle 20, first insert one of the claws 21 into the first mounting hole 141 to position the handle 20. Then slide the other claw 21 along the guide groove 121 until it is inserted into the second mounting hole 122. When the claw 21 is inserted into the second mounting hole 122, a "click" sound will be heard, indicating that the handle 20 is fixed. When disassembling, a slight external force is required to pull the claw 21 out of the second mounting hole 122 and move it along the guide groove 121 to disassemble the handle 20.

[0040] This embodiment improves the installation efficiency of the handle 20 by designing a guide groove 121 on the second mounting part, so that the handle 20 can be installed without tools, and the installation time of the handle 20 can be shortened to within 10 seconds.

[0041] See Figure 4 In some embodiments, the opening 123 of the guide groove 121 is larger than the tail end, making it easier for the claw 21 to enter the guide groove 121.

[0042] In some embodiments, the ends of both claws 21 are chamfered to reduce the insertion resistance of the claws 21.

[0043] See Figure 3 and Figure 4 In some embodiments, both the first mounting structure 14 and the second mounting structure 12 are arc-shaped. The first mounting hole 141 is located at the middle position of the first mounting structure 14, and the second mounting hole 122 is located at the middle position of the second mounting structure 12. The first mounting hole 141 and the second mounting hole 122 are arranged opposite to each other. The guide groove 121 is arc-shaped and extends from the end of the second mounting structure 12 along the extension direction of the second mounting structure 12 to the second mounting hole 122.

[0044] See Figure 7 In some embodiments, the line connecting the two ends of the handle 22 is a horizontal line, and both claws 21 are inclined relative to the horizontal line towards the handle 22. In this embodiment, the claws 21 are set at an inclination to cooperate with the guide groove 121, forming a guiding angle, which facilitates the installation of the handle 20.

[0045] In some embodiments, the angle between the claw 21 and the horizontal line is any value between 5° and 10°, such as 5°, 8° or 10°.

[0046] See Figure 3 In some embodiments, the upper cover 10 also includes a first limiting part 13, which is located on the top of the body 11. When the handle 20 is installed on the upper cover 10 and is in a horizontal state, the handle 22 is locked with the first limiting part 13, which can prevent the handle 20 from shaking during the use of the filter element 100 and ensure the stability of the filter element 100 during use.

[0047] In a preferred embodiment, the first limiting portion 13 is engaged with the middle portion of the handle portion 22. In other embodiments, the first limiting portion 13 may also be designed to engage with other parts of the handle portion 22.

[0048] See Figure 4 and Figure 5In some embodiments, the first limiting portion 13 is protruding and has a first portion 131, a second portion 132, and a third portion 133 connected in sequence. The first portion 131 protrudes outward, the second portion 132 is recessed inward, and the third portion 133 protrudes outward. The handle 22 is engaged at the second portion 132.

[0049] See Figure 9 In some embodiments, the first limiting part 13 has a disassembly groove 134 for disassembling the filter element 100. When the filter element 100 fails, it can be directly pried open through the disassembly groove 134 to achieve quick replacement of the filter element 100 and improve the convenience of disassembling the filter element 100. In addition, this embodiment integrates the disassembly groove 134 and the first limiting part 13 into a single design, which can both limit the handle 20 and facilitate the disassembly of the filter element 100, adapting to the compact layout requirements of the filter element 100 and optimizing space utilization.

[0050] In some embodiments, the inner wall of the second mounting hole 122 is provided with a second limiting portion 124, and one of the claws 21 of the handle 20 is provided with a limiting groove 212. When the claw 21 is inserted into the second mounting hole 122, the second limiting portion 124 cooperates with the limiting groove 212, thereby limiting the claw 21 within the second mounting hole 122 and preventing the handle 20 from disengaging. During disassembly, only a small force is required to pull the claw 21 out of the second mounting hole 122.

[0051] In some embodiments, the second limiting portion 124 is a protrusion and is arc-shaped, formed by a portion of the inner wall of the second mounting hole 122 protruding towards the center of the hole. The limiting groove 212 is arranged along the outer periphery of the handle 20 and is formed by a recess in the outer wall of the handle 20. When the claw enters the second mounting hole 122, the second limiting portion 124 enters the limiting groove 212, thereby limiting the claw 21. When installing the handle 20, it is necessary to observe that the claw 21 with the second limiting portion 124 needs to be inserted into the second mounting hole 122.

[0052] See Figure 1 In some embodiments, the filter element 100 further includes an upper sealing ring 30, a hydrophobic mesh 40, a central tube 50, composite filter paper 60, a lower end cap 80, and a lower sealing ring 90. The top and bottom ends of the composite filter paper 60 are connected to the upper end cap 10 and the lower end cap 80, respectively, by adhesive 70.

[0053] This embodiment addresses the problem of traditional handles 20 requiring tools for installation and being cumbersome by incorporating a guide groove 121 at the second mounting structure 12 between the handle 20 and the upper cover 10. This guide groove 121, engaging with the second mounting hole 122, enables rapid positioning and locking of the handle 20, allowing for tool-free installation and significantly improving production assembly efficiency. Furthermore, this embodiment, through standardized interfaces—the guide groove 121 and the second mounting hole 122—enhances the compatibility of the handle 20 with different filter elements 100, reducing the need for customized production. The handle 20 is pre-installed on the upper cover 10 at the factory, eliminating the need for user installation.

[0054] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
