As a common water purification device in homes and businesses, water purifiers are becoming increasingly important. Through their built-in filter systems, water purifiers effectively remove impurities, residual chlorine, heavy metals, and other harmful substances from water, providing users with safe and healthy drinking water. As a core component of a water purifier, the filter's performance and ease of replacement directly impact its effectiveness and user experience.

[0003] Currently, most water purifiers on the market use traditional methods such as screw fastening and snap-on locking to replace the filter element. These methods often require tools such as screwdrivers and wrenches when installing the filter element, making the operation cumbersome and time-consuming.

[0004] However, existing water purifiers have some shortcomings when it comes to filter cartridge replacement. They often use traditional methods such as screw fastening and snap-on locking, requiring additional tools and increasing the operator's workload. Furthermore, screws and other fastening structures can rust and strip due to external influences, making it difficult for operators to remove, replace, and maintain the filter cartridge, reducing the practicality of the water purifier. Therefore, we propose a water purifier that facilitates filter cartridge replacement to address these issues. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figure 1-5A water purifier that is easy to replace filter cartridges includes a water purifier 1. The inner top of the water purifier 1 is fixedly connected to a plurality of connecting pipe heads 4 in a linear array. A sleeve 2 is provided below the plurality of connecting pipe heads 4, and a filter cartridge body 10 is provided inside the sleeve 2. A sealing gasket 6 is fixedly connected inside the plurality of sleeves 2 and located above the filter cartridge body 10, and the inner side of the sealing gasket 6 is adapted to the outer side of the connecting pipe head 4. The main function of the sealing gasket 6 is to ensure that the connection between the sleeve 2 and the connecting pipe head 4 has good sealing. When the sleeve 2 is inserted into the connecting pipe head 4 of the water purifier 1, the sealing gasket 6 will fit tightly against the outer side of the connecting pipe head 4, preventing water or other impurities from leaking from the connection. This sealing is the key to ensuring the normal operation of the water purifier 1 and providing high-quality pure water. A mounting block 3 is fixedly connected to one side of the outer side of the sleeve 2. A positioning component 7 connected to an adjacent mounting block 3 is provided in a linear array on one side of the water purifier 1. Each positioning component 7 is tightly matched with an adjacent mounting block 3. Ensure that when the sleeve 2 is installed, the mounting block 3 can be accurately inserted into the predetermined position of the water purifier 1. This precise guiding and positioning mechanism reduces errors during the installation process and improves installation efficiency. The positioning component 7 also integrates a quick locking and unlocking mechanism, such as the combination of the spring 704, the pull rod 702 and the limit plate 703 mentioned above. This design allows personnel to quickly unlock the mounting block 3 and separate it from the water purifier 1 through simple operations (such as pulling the pull block 705) when the filter element needs to be replaced. Similarly, when installing a new filter element, just align the mounting block 3 and push it in, and the positioning component 7 will automatically complete the locking process without the need for additional tools or complicated steps.

[0024] Furthermore, mounting grooves are provided at the top of the water purifier 1 and on one side of the multiple connecting pipe heads 4. The tops of the multiple mounting blocks 3 are adapted to the mounting grooves, and a slot 5 is provided on one side of the mounting block 3. A plurality of sockets connected to the slots 5 are provided on one side of the water purifier 1. Through the arrangement of the mounting block 3 and the slot 5, the mounting block 3 is plugged into the mounting groove, thereby facilitating the connection between the sleeve 2 and the water purifier 1.

[0025] Furthermore, the positioning assembly 7 includes a mounting shell 701, a pull rod 702 and a spring 704. The mounting shell 701 is located on one side of the water purifier 1 and is in an open shape, and the side surface of the mounting shell 701 located at the opening is fixedly connected to the adjacent outer wall of the water purifier 1. Through the setting of the mounting shell 701, the mounting shell 701 can provide a protective effect for the pull rod 702 and the spring 704, thereby preventing the pull rod 702 from being affected by external forces and unable to move.

[0026] Furthermore, a limit plate 703 is provided in the mounting shell 701, and the inner side of the limit plate 703 is socketed with the outer side of the pull rod 702. One end of the pull rod 702 is plugged into the slot 5 through the socket, and the other end of the pull rod 702 passes through a side wall of the mounting shell 701 and is fixedly connected to a pull block 705. Through the setting of the pull block 705, it is convenient for personnel to hold the pull block 705 to pull the pull rod 702 to move, and it is convenient for personnel to operate the pull rod 702 in the positioning assembly 7 to fix the mounting block 3.

[0027] Furthermore, the interior of the spring 704 is nested with the exterior of the pull rod 702, and the two ends of the spring 704 are fixedly connected to one side of the limit plate 703 and the inner wall of the mounting shell 701. Through the setting of the spring 704, the personnel hold the pull block 705 and pull the pull rod 702 to drive the limit plate 703 to squeeze the spring 704. The pull rod 702 moves and separates one end of it from the slot 5 to release the positioning of the mounting block 3, making it easy for the personnel to disassemble the sleeve 2 between the mounting block 3 and the water purifier 1. Remove and replace the filter element body 10. During installation, align the inner side of the sealing gasket 6 in the sleeve 2 with the outer side of the connecting pipe head 4 and insert it. At the same time, make the mounting block 3 engage with the mounting groove. Then loosen the pull block 705 to make the spring 704 lose the extrusion force and recover elastically. Push the limit plate 703 to drive the pull rod 702 back to its position so that one end is inserted into the slot 5 to fix the mounting block 3, thereby achieving convenient loading and unloading of the sleeve 2 to replace the filter element body 10, reducing the operating burden of personnel and improving the practicality of the pure water machine 1.

[0028] Furthermore, a limiting groove is provided on the outer wall of one side of the mounting shell 701, and a circular groove is provided on the side of the pull block 705 close to the mounting shell 701. A limiting block 9 is provided on one side of the mounting shell 701 to match the limiting groove, and a plug rod 8 that matches the gap in the circular groove is fixedly connected to one side of the limiting block 9. Through the setting of the plug rod 8 and the limiting block 9, when the personnel pulls the pull block 705 to move, the personnel can drive the plug rod 8 to move to the horizontal position of the circular groove by moving the limiting block 9 in the limiting groove, and then release the pull block 705 to return the pull block 705. The circular groove on one side will abut against one end of the plug rod 8, and then position the pull block 705 so that it cannot drive the pull rod 702 to return and insert it into the slot 5, thereby making it convenient for the personnel to free up their hands to operate the loading and unloading sleeve 2 and the mounting block 3, and there is no need for the personnel to continuously pull the pull block 705 by hand, which brings convenience to the personnel operation.

[0029] In summary:

[0030] When the filter cartridge body 10 needs to be replaced, the operator simply grasps the pull block 705 and pulls it outward. This action directly acts on the pull rod 702, causing it to move outward, overcoming the elastic force of the spring 704. During this process, one end of the pull rod 702 disengages from the slot 5, releasing the lock on the mounting block 3, allowing the sleeve 2 and filter cartridge body 10 to be easily removed from the water purifier 1. When the new filter cartridge body 10 and sleeve 2 are ready for installation, the sleeve 2 simply needs to be correctly aligned and inserted into the connecting pipe head 4 of the water purifier 1, while ensuring that the mounting block 3 engages with the mounting slot. At this time, release the pull block 705, and the spring 704 immediately exerts its elastic potential energy to push the limit plate 703 and the pull rod 702 to quickly reset, so that one end of the pull rod 702 is reinserted into the slot 5, thereby achieving a secure locking of the installation block 3 and completing the installation process. Through the ingenious combination of the spring 704, the pull rod 702 and the limit plate 703, a quickly responsive disassembly structure is formed. Compared with the traditional complicated disassembly and installation process, the operation steps are greatly simplified. The convenient disassembly and installation mechanism reduces the operating burden of the personnel, reduces the inconvenience and trouble caused by replacing the filter element, and enhances the user experience of the personnel.

[0031] When the sleeve 2 and the mounting block 3 need to be removed, the person first grasps the pull block 705 and pulls it outward. At this time, the pull rod 702 moves accordingly, compresses the spring 704, and releases the lock on the mounting block 3. At the same time, the person can manually adjust the limit block 9 in the limit groove so that it drives the insertion rod 8 to move to the horizontal position of the circular groove. Once the pull block 705 is pulled far enough, the person can release the pull block 705. Since the insertion rod 8 is already in the horizontal position of the circular groove, when the pull block 705 tries to return to its original position under the elastic force of the spring 704, one end of the insertion rod 8 will enter and get stuck in the circular groove, thereby preventing the pull block 705 from being fully reset, thereby keeping the pull rod 702 in an unlocked state. In this state, the person can free his hands to focus on the disassembly and installation of the sleeve 2 and the mounting block 3 without having to continuously pull the pull block 705. When the replacement of the sleeve 2 and the mounting block 3 is completed, the personnel only need to simply move the limit block 9 and the insertion rod 8 back to their original position to disengage the insertion rod 8 from the circular groove, and the pull block 705 can automatically reset under the action of the spring 704, and the pull rod 702 is also reinserted into the slot 5 to complete the re-locking of the mounting block 3. By introducing the locking mechanism of the limit block 9 and the insertion rod 8, the user does not need to continuously pull the pull block 705 during the entire replacement process, thereby greatly improving the convenience and efficiency of the operation. The convenient locking and unlocking mechanism makes the replacement process of the filter element body 10 smoother and more intuitive, thereby improving the practicality of the pure water machine 1.
