[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A structure for a water purifier that facilitates filter replacement includes a water purifier body 1, a snap-fit ​​mechanism 2 welded to the bottom of the inner side of the water purifier body 1, a connecting mechanism 3 opened on the top of the water purifier body 1, and a filter cartridge cover 4 magnetically connected to the top of the water purifier body 1.

[0027] The snap-fit ​​mechanism 2 includes a filter element 21, a limiting seat 22, a limiting rod 23, several movable grooves 24, a return spring 25, a ball bearing 26, and a ball-locking hole 27. The filter element 21 is snapped into the inner side of the water purifier body 1. The limiting seat 22 is welded to the bottom of the inner side of the water purifier body 1. The limiting rod 23 is welded to the inner side of the limiting seat 22. The bottom of the filter element 21 is snapped into the inner side of the limiting seat 22. The inner side of the filter element 21 is slidably connected to the surface of the limiting rod 23. The movable grooves 24 are opened at the bottom of the inner wall of the filter element 21. The return spring 25 is fixedly connected to the inner side of the movable grooves 24.

[0028] In this embodiment: the water purifier body 1 improves water quality and provides an installation base for the locking mechanism 2 and the connecting mechanism 3. The filter element 21 purifies the water. The limiting seat 22 provides bottom support and positioning for the filter element 21, restricting its horizontal displacement and ensuring accurate installation. This ensures proper connection between the filter element 21 and the internal water circuit of the water purifier. The limiting rod 23 slides on the inner side of the filter element 21, limiting and guiding it vertically. This allows the filter element 21 to be inserted and removed along a fixed path, preventing it from tilting or shifting. It also works with the ball bearing 26 and the locking ball hole 27 to achieve a locking function. The movable groove 24 provides space for the return spring 25 and the ball bearing 26, allowing the ball bearing 26 to move flexibly within the groove. The return spring 25 is a locking mechanism for the ball bearing. 26 provides continuous elasticity. When the filter element 21 is inserted into place, it pushes the ball 26 to engage with the ball-locking hole 27, achieving automatic locking of the filter element 21. When disassembling the filter element 21, the upward pulling force compresses the spring, causing the ball 26 to disengage from the ball-locking hole 27 for easy operation. Under the action of the return spring 25, the ball 26 engages with the ball-locking hole 27, achieving locking of the filter element 21 through point contact. Compared with the surface contact structure, the operation is less strenuous and the locking effect is reliable. At the same time, it provides clear operational feedback to the user when engaging and disengaging from the ball-locking hole 27. The ball-locking hole 27 and the ball 26 cooperate to form a locking structure. When the ball 26 engages with the ball-locking hole 27, it restricts the vertical movement of the filter element 21, ensuring that the filter element 21 remains fixed during use and preventing the filter element 21 from loosening or falling off due to water flow impact or vibration.

[0029] Specifically, such as Figure 4 , Figure 5 As shown, the ball 26 is movably connected to the inner side of the movable groove 24, the surface of the ball 26 is in contact with the return spring 25, and the ball retaining hole 27 is opened at the bottom of the surface of the limit rod 23, and the ball 26 is engaged with the ball retaining hole 27.

[0030] Specifically, such as Figure 2 , Figure 3 As shown, the connecting mechanism 3 includes several mounting slots 31, adsorption magnets 32, adsorption blocks 33, connecting rods 34, support rods 35, rotating frames 36, insertion holes 37 and insertion rods 38. The mounting slots 31 are formed on the top surface of the water purifier body 1.

[0031] Specifically, such as Figure 2 , Figure 3 As shown, the adsorption magnet 32 ​​is installed on the inner side of the mounting groove 31, the adsorption block 33 is welded to the inner wall of the filter cartridge cover 4, the adsorption magnet 32 ​​and the adsorption block 33 are magnetically connected, and the connecting rod 34 is welded to the top of both sides of the water purifier body 1.

[0032] In this embodiment: An installation groove 31 is provided for installing the adsorption magnet 32, allowing the magnet 32 ​​to be embedded securely without affecting the overall flatness and aesthetics of the top of the water purifier body 1. This also facilitates alignment and adsorption with the adsorption block 33 on the filter cartridge cover 4. The adsorption magnet 32 ​​uses its strong magnetism to magnetically connect with the adsorption block 33, achieving rapid closure and initial fixation of the filter cartridge cover 4, simplifying the operation process and eliminating the need for tedious screw tightening. The adsorption block 33 attracts the adsorption magnet 32. The connecting rod 34 provides an installation base for the support rod 35, and through cooperation with the support rod 35, provides support and an installation position for the rotating frame 36. The support rod 35 supports the rotating frame 36. 6. This allows the rotating frame 36 to rotate on both sides, providing a stable fulcrum for its rotation and ensuring smooth and flexible operation during opening and closing. The rotating frame 36 achieves opening and closing by rotation. After the filter cartridge cover 4 is initially fixed by magnetic attraction, the rotating frame 36 is rotated to align with the insertion hole 37 on the top of the filter cartridge cover 4. Then, the insertion rod 38 is inserted to mechanically reinforce the filter cartridge cover 4. This, combined with the magnetic connection, forms a double lock, improving the stability and sealing of the cover. The insertion hole 37 provides an insertion channel for the insertion rod 38, which connects the rotating frame 36 and the filter cartridge cover 4 to achieve a mechanical locking function, firmly fixing the filter cartridge cover 4 to the top of the water purifier body 1 and preventing accidental opening of the cover.

[0033] Specifically, such as Figure 2 , Figure 3 As shown, the support rod 35 is welded to the surface of the connecting rod 34, the rotating frame 36 is rotatably connected to the surfaces on both sides of the support rod 35, the insertion holes 37 are respectively opened on the top of the rotating frame 36 and the top of the filter element cover 4, and the insertion rod 38 is inserted into the inside of the insertion hole 37.

[0034] Specifically, such as Figure 1 As shown, a pull ring 5 is welded to the top of the plug rod 38, and the surface of the pull ring 5 is engraved with anti-slip texture.

[0035] In this embodiment: by providing a pull ring 5, it is convenient for the user to insert and remove the plug rod 38, and by providing anti-slip texture, the friction between the user's fingers and the pull ring 5 is increased.

[0036] Specifically, such as Figure 2 As shown, a sealing ring 6 is fixedly connected to the top of the insertion hole 37, and the inner side of the sealing ring 6 is in contact with the surface of the insertion rod 38.

[0037] Specifically, such as Figure 2 As shown, the adsorption magnet 32 ​​is made of neodymium iron boron magnet material, and the adsorption block 33 is made of ferritic stainless steel material.

[0038] In this embodiment: By setting a sealing ring 6, a sealing structure is formed after the plug rod 38 is inserted into the plug hole 37, effectively preventing external moisture, dust, etc. from entering the water purifier through the plug hole 37, further improving the water purifier's sealing and protective performance. By setting the adsorption magnet 32 ​​to be made of neodymium iron boron magnet material, neodymium iron boron magnets have strong magnetism and can generate a large adsorption force, so that the filter cartridge cover 4 and the water purifier body 1 can be quickly and tightly magnetically connected, ensuring that the cover will not easily fall off during normal use. At the same time, it can be easily separated when replacing the filter cartridge 21, reducing the difficulty of operation. By setting the adsorption block 33 to be made of ferritic stainless steel material, ferritic stainless steel material has both magnetic properties and good rust resistance. As the material of the adsorption block 33, it can not only attract each other with the adsorption magnet 32 ​​to achieve the magnetic connection function, but also maintain the structural integrity for a long time in the humid water purifier use environment, avoiding the decrease in adsorption performance or structural damage due to rust.

[0039] Working principle: First, when the filter element 21 needs to be installed, the user inserts the filter element 21 with its bottom aligned with the inside of the limiting seat 22. The inside of the filter element 21 slides along the surface of the limiting rod 23. During this process, the return spring 25 in the movable groove 24 at the bottom of the inner wall of the filter element 21 is compressed, and the ball 26 retracts into the movable groove 24. Then, when the filter element 21 is fully inserted, the return spring 25 returns to its original shape, pushing the ball 26 into the ball-holding hole 27 at the bottom of the surface of the limiting rod 23, thus automatically locking the filter element 21 in the vertical direction. At the same time, the limiting seat 22 restricts the horizontal displacement of the filter element 21. The limiting rod 23 and the ball 26 cooperate to ensure that the filter element 21 is installed in an accurate position. Then, when installing the filter element cover 4, the user places the filter element cover 4 on top of the water purifier body 1. The adsorption block 33 on the inner wall of the filter element cover 4 is magnetically connected to the neodymium iron boron adsorption magnet 32 ​​in the mounting groove 31, completing the initial fixation of the filter element cover 4. Then, the user rotates the two rotating brackets 36 to align the top insertion hole 37 with the insertion holes 37 on both sides of the top of the filter element cover 4. Next, the user inserts the insertion rod 38 into the insertion hole 37. At this time, the sealing ring 6 contacts the surface of the insertion rod 38 to form a seal, mechanically reinforcing the filter element cover 4 and forming a double lock of magnetic attraction and mechanical locking. Finally, when it is necessary to remove the filter element 21, the user separates the insertion rod 38 from the filter element cover 4. Then, the user pulls the filter element 21 upward. The ball bearing 26 is pulled and compresses the return spring 25 to disengage from the ball retainer hole 27, and the filter element 21 can be pulled out from the limiting seat 22 to complete the operation.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
