[0004] However, the implementation of the relevant technologies revealed the following problems: Most water purification devices on the market currently suffer from inconvenient filter replacement. Some devices require specialized tools to disassemble and install the filter, which is difficult for ordinary users to operate independently. This necessitates waiting for professional service, increasing users' time and expenses, and potentially affecting the normal operation of the device due to excessive waiting time. Furthermore, some devices have complex filter fixing structures, making them prone to component damage and improper installation during replacement. This not only affects the water purification effect but may also lead to safety hazards such as leaks.

[0005] Therefore, we propose a water purification device that allows for easy replacement of the filter cartridge. Utility Model Content

[0013] Preferably, the upper surface of the filter element is provided with a water inlet.

[0014] Preferably, the lower surface of the filter cartridge shell is provided with a water outlet.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the combination of the insert block and slot, the rotating groove, and the elastic fixing structure composed of spring, limit plate, and card block, can quickly fix and separate the filter element from the filter cartridge shell. When the filter element needs to be replaced, simply pull the pull ring to release the fixation. The operation is simple and convenient, and no professional tools are required. Ordinary users can complete the operation independently, which greatly reduces the difficulty of use and maintenance costs for users and avoids the situation of waiting for professional personnel to come to the site to affect the normal use of the equipment.

[0016] 2. This utility model uses a sealing ring on the top side of the filter element to fit tightly against the inner wall of the filter cartridge shell, effectively preventing water leakage during equipment operation, ensuring the sealing performance and safety of the equipment. Furthermore, this device is less prone to component damage or improper installation during long-term use, which helps maintain a stable water purification effect, extends the service life of the equipment, and provides users with a more reliable and convenient water purification service.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, this utility model provides a water purification device that facilitates filter replacement, including a filter cartridge shell 1. The inner surface of the filter cartridge shell 1 is provided with a slot 2. The bottom end of the slot 2 is provided with a rotating groove 3. The top of the rotating groove 3 is provided with a slot. An installation plate 4 is fixedly connected in the slot. A spring 5 is fixedly connected to the lower surface of the installation plate 4. The other end of the spring 5 is fixedly connected to a limiting plate 6. A locking block 7 is fixedly connected to the lower surface of the limiting plate 6. A filter cartridge 8 is detachably connected inside the filter cartridge shell 1. An insert block 9 is fixedly connected to the outer surface of the filter cartridge 8. A locking groove 10 is provided on the upper surface of the insert block 9. A sealing ring 11 is fixedly connected to the top side of the filter cartridge 8. The filter cartridge 8 includes a shell 12 and several filter layers 13 located inside the shell 12.

[0021] Specifically, the card block 7 engages with the card slot 10, and the lower end of the card block 7 is rounded.

[0022] Furthermore, the insert 9 is slidably connected to the slot 2, and the insert 9 is slidably connected to the rotating groove 3.

[0023] Furthermore, the limiting plate 6 is slidably connected to the slot, and is used to slide within the slot through the limiting plate 6 to limit the movement range of the locking block 7.

[0024] It is worth noting that a pull rod 16 is fixedly connected to the upper surface of the limiting plate 6, and the pull rod 16 is slidably connected to the mounting plate 4 and the filter cartridge housing 1.

[0025] It is worth noting that the other end of the pull rod 16 is rotatably connected to a pull ring 17, and a rubber sleeve 18 is fixedly connected to the outer surface of the pull ring 17 to facilitate pulling the limit plate 6 and the locking block 7.

[0026] It is worth mentioning that the upper surface of the filter element 8 is provided with a water inlet 14 for water intake into the equipment.

[0027] It is worth emphasizing that the lower surface of the filter cartridge housing 1 is provided with a water outlet 15 for the equipment to discharge water.

[0028] Among them, filter element 8 is existing technology and will not be described in detail; at the same time, this utility model also includes power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0029] Working principle: During use, the water to be treated enters the equipment through the inlet 14 of the filter element 8. The water flows through several filter layers 13 inside the housing 12, which filter and purify impurities and pollutants in the water. The purified water is finally discharged through the outlet 15 on the lower surface of the filter cartridge housing 1, completing the water purification process. When the filter element 8 needs to be replaced, the operator pulls the pull ring 17. The pull ring 17 drives the pull rod 16 to move upward. The pull rod 16 pulls the limiting plate 6 to slide upward in the slot. The limiting plate 6 compresses the spring 5, and at the same time, it drives the locking block 7 to disengage from the locking groove 10 on the insertion block 9, releasing the fixing restriction on the filter element 8. Then, the filter element 8 is rotated and pulled upward, so that the insertion block 9 on the outer surface of the filter element 8 slides from the rotating groove 3 on the inner surface of the filter cartridge housing 1 to the slot 2. Then, the old filter element 8 is taken out upward along the slot 2. When installing the new filter element 8, align the insert 9 of the new filter element 8 with the slot 2 and insert it downwards. When the insert 9 slides to the position of the rotating groove 3, rotate the filter element 8 to move the insert 9 to the designated position within the rotating groove 3. At this time, release the pull ring 17, the spring 5 returns to its original deformation, and pushes the limiting plate 6 downwards. The limiting plate 6 drives the locking block 7 to engage with the locking groove 10 of the insert 9, thus completing the fixing of the new filter element 8. At the same time, the sealing ring 11 on the top side of the filter element 8 fits tightly against the inner wall of the filter cartridge housing 1, ensuring the airtightness of the equipment and preventing water leakage.
