[0002] With social development and improved living standards, more and more people are paying attention to drinking water health. Water quality is closely related to people's health, thus the market demand for water purification equipment is expanding rapidly. As the core component of water purification equipment, the filter cartridge directly affects the purification effect. Currently, the filter cartridges used in water purification equipment have a limited lifespan. When the filter cartridge reaches its lifespan, it needs to be replaced to ensure the purification effect of the equipment. For this reason, a filter cartridge handle is usually installed at the end of the cartridge to make replacement and disassembly more convenient. However, the filter cartridge handle takes up space, increasing the overall size of the filter cartridge and affecting the overall spatial layout of the water purification equipment.

[0003] It should be noted that the above content is only used to help understand the technical solution of this utility model, and does not represent an admission that the above content is prior art. Utility Model Content

[0004] The main purpose of this utility model is to propose a filter element handle structure and a filter element, aiming to design the filter element handle as a hidden structure so that the overall volume of the filter element remains unchanged during non-replacement and disassembly processes.

[0005] To achieve the above objectives, this utility model proposes a filter element handle structure, which is installed on the filter element;

[0006] Specifically, the filter element handle structure includes a handle body; the filter element has a recessed receiving cavity, and the handle body can slide relative to the receiving cavity to a first position and a second position; when the handle body slides to the first position, the handle body is housed in the receiving cavity; when the handle body slides to the second position, the handle body extends out of the receiving cavity;

[0007] The handle body includes a lifting handle and connecting parts disposed on opposite sides of the lifting handle, with a sliding block provided on one side of each connecting part facing each other; the receiving cavity is provided with a sliding groove, and the sliding block is slidably connected to the sliding groove.

[0008] In one embodiment, the sliding block includes a first sliding portion and a second sliding portion, the second sliding portion being disposed on the side of the first sliding portion away from the connecting portion; wherein the cross-sectional width of the second sliding portion is greater than the cross-sectional width of the first sliding portion;

[0009] The sliding groove is provided with abutting parts on both sides along the groove. The area between the two abutting parts forms a first sliding channel, and the area between the abutting part and the bottom of the sliding groove forms a second sliding channel. The cross-sectional width of the first sliding channel is greater than the cross-sectional width of the first sliding part and less than the cross-sectional width of the second sliding part. The first sliding part slides in the first sliding channel, and the second sliding part slides in the second sliding channel.

[0010] In one embodiment, the first sliding part has a square cross-section, and the second sliding part has a trapezoidal cross-section. Both the first sliding part and the second sliding part are symmetrically arranged along the same central axis.

[0011] In one embodiment, the sliding groove has an insertion cavity at its groove-oriented end, and the insertion cavity is connected to the first sliding channel and the second sliding channel; the first sliding part moves to the first sliding channel through the insertion cavity, and the second sliding part moves to the second sliding channel through the insertion cavity.

[0012] In one embodiment, the connecting portion has a concave structure on its opposite two side edges and on the side facing the receiving cavity, the concave structure extending along the length of the connecting portion; the concave structure extends to the free end side of the connecting portion, the free end side of the connecting portion is defined as the end structure, and the connection between the end structure and the concave structure forms a stepped portion;

[0013] The inner wall of the receiving cavity is provided with a limiting block. When the handle body slides to the second position, the limiting block abuts against the step portion.

[0014] In one embodiment, the end structure is provided with a recessed travel groove; the inner wall of the receiving cavity is provided with a travel block, and when the handle body slides to the first position, the travel block engages with the travel groove.

[0015] In one embodiment, the surface of the limiting block is in contact with the surface of the concave structure.

[0016] In one embodiment, the concave structure extends to the side edge of the handle portion so that the concave structures of the two connecting portions are interconnected.

[0017] In one embodiment, when the handle body is slid to the first position, the outer surface of the handle body and the outer surface of the filter element are on the same plane.

[0018] To achieve the above objectives, this utility model proposes a filter element, which includes a filter element handle structure as described in any of the above claims.

[0019] The technical solution of this utility model is to set a receiving cavity in the filter element, and the handle body can slide to a first position and a second position relative to the receiving cavity. When it is not in the replacement and disassembly state, the handle body is slid to the first position, at which time the handle body is stored in the receiving cavity, so that the overall volume of the filter element remains unchanged during the non-replacement and disassembly process, so that there is no need to worry about the handle body affecting the overall space layout of the water purification equipment. When it is in the filter element replacement and disassembly state, the handle body is slid to the second position, at which time the handle body extends out of the receiving cavity, so that the operator can install, remove or move the filter element through the handle body, improving the convenience of using the filter element. The above structure realizes the design of the filter element handle as a hidden structure.

[0020] The handle body includes a lifting handle and connecting parts on opposite sides of the lifting handle, thus forming a U-shaped structure for the operator to grip and move the filter element. Sliding blocks and sliding grooves are respectively provided in the connecting parts and the receiving cavity. The sliding connection between the sliding blocks and the sliding grooves ensures that the handle body remains stable during sliding and also prevents the handle body from sliding excessively relative to the receiving cavity and detaching from the filter element, thereby improving the reliability and stability of the filter element handle structure.

[0032] With social development and improved living standards, more and more people are paying attention to drinking water health. Water quality is closely related to people's health, thus the market demand for water purification equipment is expanding rapidly. As the core component of water purification equipment, the filter cartridge directly affects the purification effect. Currently, the filter cartridges used in water purification equipment have a limited lifespan. When the filter cartridge reaches its lifespan, it needs to be replaced to ensure the purification effect of the equipment. For this reason, a filter cartridge handle is usually installed at the end of the cartridge to make replacement and disassembly more convenient. However, the filter cartridge handle takes up space, increasing the overall size of the filter cartridge and affecting the overall spatial layout of the water purification equipment.

[0033] To solve the above-mentioned technical problems, this utility model proposes a filter element handle structure.

[0034] Please see Figures 1 to 3 In one embodiment of this utility model, the filter element handle structure is installed on the filter element 100;

[0035] Specifically, the filter element handle structure includes a handle body 200; the filter element 100 is provided with a recessed receiving cavity 300, and the handle body 200 can slide relative to the receiving cavity 300 to a first position and a second position; when the handle body 200 slides to the first position, the handle body 200 is housed in the receiving cavity 300; when the handle body 200 slides to the second position, the handle body 200 extends out of the receiving cavity 300.

[0036] The handle body 200 includes a handle portion 400 and connecting portions 500 disposed on opposite sides of the handle portion 400. A sliding block 510 is provided on one side of the connecting portions 500 that are opposite to each other. The receiving cavity 300 is provided with a sliding groove 310, and the sliding block 510 is slidably connected to the sliding groove 310.

[0037] The technical solution of this utility model is to provide a receiving cavity 300 in the filter element 100, and the handle body 200 can slide to a first position and a second position relative to the receiving cavity 300. When not in the replacement / disassembly state, the handle body 200 is slid to the first position, at which time the handle body 200 is stored in the receiving cavity 300, so that the overall volume of the filter element 100 remains unchanged during the non-replacement / disassembly process, so that there is no need to worry about the handle body 200 affecting the overall space layout of the water purification equipment. When the filter element 100 is in the replacement / disassembly state, the handle body 200 is slid to the second position, at which time the handle body 200 extends out of the receiving cavity 300, so that the operator can install, disassemble or move the filter element 100 through the handle body 200, thereby improving the ease of use of the filter element 100. The above structure realizes the design of the handle of the filter element 100 as a hidden structure.

[0038] The handle body 200 includes a handle portion 400 and connecting portions 500 disposed on opposite sides of the handle portion 400, thereby forming a U-shaped structure for the operator to grip and move the filter element 100 through the handle body 200. A sliding block 510 and a sliding groove 310 are respectively provided in the connecting portion 500 and the receiving cavity 300. The sliding connection between the sliding block 510 and the sliding groove 310 ensures that the handle body 200 remains stable during sliding, and also prevents the handle body 200 from sliding excessively relative to the receiving cavity 300 and detaching from the filter element 100, which helps to improve the reliability and stability of the filter element handle structure.

[0039] As a preferred embodiment of the above embodiments, refer to Figure 4 The sliding block 510 includes a first sliding part 511 and a second sliding part 512. The second sliding part 512 is disposed on the side of the first sliding part 511 away from the connecting part 500. The cross-sectional width of the second sliding part 512 is greater than the cross-sectional width of the first sliding part 511. The sliding groove 310 is provided with abutment parts 313 on both sides along the groove. The area between the two abutment parts 313 forms a first sliding channel 311. The area between the abutment parts 313 and the bottom of the groove of the sliding groove 310 forms a second sliding channel 312. The cross-sectional width of the first sliding channel 311 is greater than the cross-sectional width of the first sliding part 511 and less than the cross-sectional width of the second sliding part 512. The first sliding part 511 slides on the first sliding channel 311, and the second sliding part 512 slides on the second sliding channel 312. With this configuration, the sliding block 510 is divided into a first sliding part 511 and a second sliding part 512, and the cross-sectional width of the second sliding part 512 is greater than the cross-sectional width of the first sliding part 511. The first sliding channel 311 and the second sliding channel 312 in the sliding groove 310 are respectively matched with it. This design allows the sliding block 510 to move more stably in the corresponding channel during sliding. At the same time, since the cross-sectional width of the first sliding channel 311 is greater than the cross-sectional width of the first sliding part 511 and less than the cross-sectional width of the second sliding part 512, the second sliding part 512 cannot pass through the first sliding channel 311 to disengage from the second sliding channel 312. This provides a limiting effect between the sliding block 510 and the sliding groove 310, preventing the handle body 200 from separating from the receiving cavity 300, and further improving the stability and safety of the filter handle structure.

[0040] Furthermore, the first sliding part 511 has a square cross-section, and the second sliding part 512 has a trapezoidal cross-section. Both the first sliding part 511 and the second sliding part 512 are symmetrically arranged along the same central axis. This symmetrical structural design makes the machining of the sliding block 510 more convenient, ensuring machining accuracy and quality. During assembly, the symmetrical structure also makes it easier to achieve accurate matching between the sliding block 510 and the sliding groove 310, improving assembly efficiency and assembly quality.

[0041] Furthermore, the groove end of the sliding groove 310 is provided with an insertion cavity 314, which communicates with the first sliding channel 311 and the second sliding channel 312. The first sliding part 511 moves to the first sliding channel 311 through the insertion cavity 314, and the second sliding part 512 moves to the second sliding channel 312 through the insertion cavity 314. With this configuration, the groove end of the sliding groove 310 has an insertion cavity 314, allowing the first sliding part 511 and the second sliding part 512 to move to the first sliding channel 311 and the second sliding channel 312 respectively. This design provides a convenient entry point for the installation of the sliding block 510, enabling it to smoothly enter the sliding groove 310 and simplifying the assembly process of the filter element handle structure. Understandably, the cross-sectional width of the insertion cavity 314 should be greater than the cross-sectional width of the first sliding part 511 and the second sliding part 512, so as to ensure that the first sliding part 511 and the second sliding part 512 can be moved to the first sliding channel 311 and the second sliding channel 312 respectively through the insertion cavity 314.

[0042] As a preferred embodiment of the above embodiment, the connecting portion 500 has a concave structure 520 on the opposite two side edges and on the side facing the receiving cavity 300. The concave structure 520 extends along the length of the connecting portion 500. The concave structure 520 extends to the free end side of the connecting portion 500. The free end side of the connecting portion 500 is defined as the end structure 530. The connection between the end structure 530 and the concave structure 520 forms a step portion 540. The inner sidewall of the receiving cavity 300 is provided with a limiting block 320. When the handle body 200 slides to the second position, the limiting block 320 and the step portion 540 abut against each other. With this configuration, the concave structure 520 of the connecting portion 500 cooperates with the limiting block 320. When the handle body 200 slides to the second position, the limiting block 320 abuts against the step portion 540, which can accurately position the sliding position of the handle body 200, preventing the handle body 200 from sliding excessively and separating from the filter element 100 during use. It also ensures that the handle can stably extend out of the receiving cavity 300 in the second position, making it convenient for the operator to grip and operate. At the same time, the concave structure 520 extends along the length of the connecting portion 500 and extends to the free end side of the connecting portion 500 to form the end structure 530 and the step portion 540. This structural design makes the concave structure 520 and the end structure 530 naturally form a whole, optimizing the spatial layout of the filter element handle structure, making the entire structure more compact, and facilitating the miniaturization design of the filter element 100.

[0043] Furthermore, the end structure 530 is provided with a recessed travel groove 531; the inner wall of the receiving cavity 300 is provided with a travel block 330. When the handle body 200 slides to the first position, the travel block 330 engages with the travel groove 531. This configuration ensures that when the handle body 200 slides to the first position, the travel block 330 engages with the travel groove 531, firmly fixing the handle body 200 within the receiving cavity 300. This prevents the handle from accidentally sliding out due to external force when stored, ensuring the stability of the handle structure during non-replacement / removal of the filter element 100. Simultaneously, the engaging connection design makes switching between storage and use of the handle body 200 more convenient. Operators only need to perform a simple pushing operation to overcome the engaging force between the travel block 330 and the travel groove 531 to fix and release the handle body 200, improving the ease of operation of the filter element handle structure and enhancing the user experience.

[0044] Furthermore, the surface of the limiting block 320 is in close contact with the surface of the concave structure 520. This arrangement increases the contact area and friction between the connecting part 500 and the receiving cavity 300, further enhancing the stability of the handle body 200 in the second position, preventing the handle from shaking or loosening during use, and improving the performance of the filter element handle structure.

[0045] Furthermore, the concave structure 520 extends to the side edge of the handle, so that the concave structures 520 of the two connecting parts 500 are interconnected. This arrangement, where the concave structure 520 extends to the side edge of the handle and the concave structures 520 of the two connecting parts 500 are interconnected, optimizes the overall layout of the filter element handle structure, making the structure more compact and harmonious. At the same time, the interconnected concave structures 520 are also more visually appealing, contributing to improved appearance quality of the filter element 100.

[0046] As a preferred embodiment of the above, when the handle body 200 is slid to the first position, the outer surface of the handle body 200 and the outer surface of the filter element 100 are on the same plane. This arrangement makes the overall appearance of the filter element 100 more flat and beautiful after the handle body 200 is placed in it. The filter element 100 and the handle body 200 are combined to form a complete integral structure, which helps to improve the appearance quality of the filter element 100.

[0047] This utility model also discloses a filter element, including the filter element handle structure of any of the above embodiments. For the specific structure of the filter element handle, please refer to the above embodiments. Since this filter element adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.

[0048] It should be noted that the filter handle structure and other contents of the filter disclosed in this utility model are existing technologies and will not be described in detail here.

[0049] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any application of this utility model directly or indirectly in other related technical fields is included within the patent protection scope of this utility model.
