[0026] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0027] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0029] An embodiment of this utility model provides a filter cartridge compression block for a water purifier, such as... Figure 1-7 As shown, it includes:

[0030] The filter element press body 100 is provided with a receiving groove 110, an installation groove 120 and a pressure relief groove 130. The receiving groove 110 is used to receive the filter element, the installation groove 120 is used for inserting and fixing the filter element, the receiving groove 110 and the installation groove 120 are connected, and the pressure relief groove 130 is used for venting air during filter element installation.

[0031] like Figure 1-5 As shown, the receiving groove 110 is a space inside the filter element pressing block body 100, used to place the filter element. The mounting groove 120 is another space inside the filter element pressing block body 100, which, through cooperation with the filter element, firmly fixes the filter element in the filter element pressing block, preventing the filter element from loosening or shifting during use.

[0032] The pressure relief groove 130 is used to expel air during filter cartridge installation. During installation, the pressure relief groove 130 releases air between the filter cartridge and the filter cartridge holder, preventing problems caused by air accumulation that could hinder filter cartridge rotation. By expelling air, the pressure relief groove 130 helps balance the internal pressure of the filter cartridge holder. This design is simple and easy to manufacture. The rational layout of the receiving groove 110, mounting groove 120, and pressure relief groove 130 satisfies both the installation requirements of the filter cartridge and ensures its stability and reliability during use. The design of the pressure relief groove 130 effectively improves the installation efficiency of the filter cartridge, reduces installation problems caused by air accumulation, and thus improves the overall performance of the water purifier.

[0033] In some embodiments, a pressure relief groove 130 is disposed at the bottom of the filter element block body 100, and the pressure relief groove 130 connects the receiving groove 110 and the outer side of the turntable 10.

[0034] The pressure relief groove 130 is connected to the receiving groove 110, ensuring that air in the receiving groove 110 can be discharged through the pressure relief groove 130 during filter cartridge installation. This connection design effectively prevents air from accumulating in the receiving groove 110. By connecting to the outside of the turntable 10, the pressure relief groove 130 can guide the discharged air to the outside of the filter cartridge block, further ensuring that the air inside the filter cartridge block can be completely discharged. This design helps to better balance the pressure inside and outside the filter cartridge block. By optimizing the exhaust path and pressure balance, this design can significantly improve the installation effect and performance of the filter cartridge, ensuring the efficient operation of the water purifier.

[0035] Furthermore, two pressure relief grooves 130 are provided, and the two pressure relief grooves 130 are respectively provided on both sides of the filter element pressing block body 100.

[0036] The two pressure relief grooves 130 can operate simultaneously, significantly improving exhaust efficiency and ensuring faster air discharge during filter element installation. Even if one pressure relief groove 130 malfunctions for some reason (such as blockage), the other pressure relief groove 130 can still continue to function, ensuring the normal operation of the entire system. The separately arranged pressure relief grooves 130 can more evenly discharge air between the filter element and the filter element block, ensuring that air inside the entire filter element block is effectively discharged and avoiding localized air accumulation. In some embodiments, the pressure relief grooves 130 are symmetrically arranged. A symmetrical layout makes the filter element block more structurally balanced, reducing stress concentration problems that may arise from asymmetrical design, thereby improving the mechanical strength and service life of the filter element block.

[0037] In some embodiments, the filter element block body 100 includes a housing 140, an upper baffle 150 and a lower baffle ring 160, and a mounting groove 120 is disposed between the upper baffle 150 and the lower baffle ring 160.

[0038] The outer casing 140 is the external structure of the filter cartridge block, serving to protect and secure the internal components. The mounting groove 120 is located between the upper baffle 150 and the lower baffle ring 160, forming an annular space. The mounting groove 120, by engaging with the filter cartridge mounting portion, firmly secures the filter cartridge within the filter cartridge block, preventing it from loosening or shifting during use. This design makes filter cartridge installation more convenient; simply insert the filter cartridge into the mounting groove 120 to complete the fixation.

[0039] Furthermore, the pressure relief groove 130 is provided in the lower retaining ring 160 and the pressure relief groove 130 passes through the lower retaining ring 160.

[0040] like Figure 6-7 As shown, the lower baffle ring 160 is located at the bottom of the filter element. Positioning the pressure relief groove 130 here allows for more effective air removal from the bottom of the filter element, ensuring smooth air discharge during installation. The pressure relief groove 130 penetrates the lower baffle ring 160, forming a channel. By penetrating the lower baffle ring 160, the pressure relief groove 130 better balances the internal and external pressures of the filter element block, ensuring the filter element functions properly after installation.

[0041] Furthermore, the lower baffle ring 160 is also provided with a ramp 131. In the direction from the inside to the outside of the filter element pressing block body 100, the height of the ramp 131 gradually decreases, and the bottom of the ramp 131 connects with the pressure relief groove 130.

[0042] The design of the ramp section 131 can guide air and optimize the internal fluid dynamics of the filter cartridge, allowing it to flow more smoothly from inside the filter cartridge to the pressure relief groove 130, thereby improving exhaust efficiency.

[0043] In some embodiments, the pressure relief groove 130 is also provided on the upper stop block 150 and the pressure relief groove 130 extends through the upper stop block 150.

[0044] like Figure 6-7 As shown, the pressure relief groove 130 is not only provided in the lower baffle ring 160, but also in the upper baffle block 150. The presence of pressure relief grooves 130 in both the upper baffle block 150 and the lower baffle ring 160 allows for more comprehensive drainage of air generated during filter element installation, ensuring complete removal of air from the filter element's interior and surrounding area. The two pressure relief grooves 130 in different positions work together to provide double protection; even if one pressure relief groove 130 fails, the other can continue to operate, improving system reliability. By providing pressure relief grooves 130 in both the upper and lower positions, the fluid dynamics within the filter element block can be better optimized, ensuring smoother air and water flow.

[0045] In some embodiments, the outer side of the housing 140 is provided with a positioning structure 141 for positioning it.

[0046] The positioning structure 141 ensures precise installation of the filter cartridge in the water purifier, preventing performance issues caused by inaccurate installation. The positioning structure 141 facilitates the installation and removal of the filter cartridge, making daily maintenance and replacement easier for users. It prevents misalignment of the filter cartridge during installation, ensuring proper functioning. The positioning structure 141 can be a slot or clip, used to engage with corresponding mounting slots or other fixing components of the water purifier. Alternatively, the positioning structure 141 can be a guide groove or guide post, used to guide the installation direction of the filter cartridge, ensuring accurate installation in the designated position.

[0047] Furthermore, the positioning structure 141 is a groove 142 or a protrusion 143.

[0048] The positioning structure 141 can be a groove 142, located on the outer side of the housing 140. The groove 142 can mate with the mounting protrusion 143 or other fixing components of the water purifier to ensure that the filter cartridge is accurately installed in the predetermined position. Alternatively, the positioning structure 141 can be a protrusion 143, located on the outer side of the housing 140. The protrusion 143 can mate with the mounting groove or other fixing components of the water purifier to ensure that the filter cartridge is accurately installed in the predetermined position.
