[0023] 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.

[0024] Please see Figure 1-4A filtration structure for a circulating water system includes a mounting frame 1, a water flow channel 2, a tank 3, a filter layer 4, a mounting groove 5, a mounting block 6, an installation device, and an unlocking device. The mounting frame 1 has the water flow channel 2 running vertically through it. Multiple sets of tanks 3 are formed on one side wall of the mounting block 6. The filter layer 4 is filled with filter material. The mounting block 6 is installed at the end of the filter layer 4 away from the tanks 3. The inner end of the tanks 3 has the mounting groove 5. The filter layer 4 and the tanks 3 are compatible, and the mounting block 6 and the mounting groove 5 are compatible. Two sets of locking blocks 7 are installed at both ends of the 6 via the mounting device. Locking slots 8 are provided at both ends of the mounting groove 5. The locking slots 8 and the locking blocks 7 are adapted to each other. The ends of both the locking slots 8 and the locking blocks 7 are designed with bevels. In this embodiment, the installation and disassembly of the filter structure are performed as follows: First, the filter layer 4 filled with filter material is inserted into the groove 3, ensuring a tight fit between the filter layer 4 and the groove 3. Then, the mounting block 6 at the end of the filter layer 4 enters the mounting groove 5. When the mounting block 6 is inserted into the mounting groove 5, the bevel design at the end of the locking block 7 will... The locking block 7, guided by the inner wall of the mounting groove 5, automatically compresses and smoothly enters the mounting groove 5 under the action of the installation device. Once installed in place, the locking block 7 will pop outward under the action of elastic restoring force and lock into the corresponding locking groove 8, achieving quick locking. Multiple filter layers 4 are installed in sequence. At this time, the filter structure is firmly installed inside the mounting frame 1. The mounting frame 1 is then installed into the circulating water system, and the water flow can be circulated through the water flow channel 2. The filling material can be filled according to the actual filtration needs, such as quartz sand, activated carbon, or zeolite. When it is necessary to replace the filter layer... 4. During cleaning, pressure is applied to the locking block 7 using the unlocking device to disengage it from the locking groove 8. After being pressed, the locking block 7 slides along the inclined surface and retracts to the surface of the mounting block 6, thereby releasing the locking state. At this time, the mounting block 6, along with the groove 3 and the filter layer 4, can be easily removed from the mounting groove 5 to complete the disassembly. After replacing the new filter layer 4, the above installation steps are repeated to put it back into use. The modular design allows the filter layer 4 to be quickly plugged in and installed by cooperating with the mounting block 6 and the mounting groove 5. Each set of filter layers 4 can be replaced individually, avoiding the replacement of the entire equipment and saving materials and operating costs.

[0025] Preferably, in this embodiment, the installation device includes a storage groove 9, a spring 10, and a guide device. Storage grooves 9 are provided at both the front and rear ends of the installation block 6. The locking block 7 is slidably connected to the storage groove 9. The spring 10 is installed between the storage groove 9 and the locking block 7. The guide device is installed at both the upper and lower ends of the storage groove 9. When not inserted into the installation groove 5, the locking block 7 extends outward under the action of the spring 10, and is in a ready-to-lock position. The groove 3 with the filter layer 4 is vertically inserted into the installation groove 5 of the installation frame 1 through the installation block 6. During installation, the inclined surface at the front end of the locking block 7 is aligned with the installation groove 5. The inner wall of the mounting groove 5 first contacts the device, is squeezed and retracts inward. The guide device guides the locking block 7 to slide smoothly along the set trajectory. As the mounting block 6 continues to move, when it reaches the preset position, the locking block 7 is completely released from the constraint and pops out to both ends under the push of the spring 10. The end of the locking block 7 is locked into the locking groove 8 in the mounting groove 5, completing the automatic locking. This structure not only improves the installation efficiency and operational stability of the equipment, but also has good modular characteristics, which facilitates maintenance and replacement. Compared with the traditional bolt fixing method, it has higher practicality and promotion value, and is especially suitable for circulating water treatment systems that require frequent replacement of filter materials.

[0026] Preferably, in this embodiment, the guiding device includes a guide groove 11 and a guide block 12. Guide grooves 11 are provided at both the upper and lower ends of the locking block 7, and guide blocks 12 are installed at both the upper and lower ends of the locking block 7. The guide blocks 12 and the guide grooves 11 are slidably connected. Before any operation is performed, the locking block 7 is located in the receiving groove 9, with outward pressure provided by the spring 10. However, because the guide block 12 is confined within the guide groove 11, the locking block 7 remains stationary. When the tank 3 with the filter layer 4 is vertically inserted into the mounting frame 1 via the mounting block 6... When the locking block 7 is in the groove 5, the inner wall of the groove 5 will apply pressure to the inclined surface at the front end of the locking block 7. At this time, the guide block 12 begins to slide in the guide groove 11, guiding the locking block 7 to retract inward along a straight line. The guide block 12 and the guide groove 11 are tightly fitted to ensure that the locking block 7 will not tilt or get stuck due to lateral force. The design of the guide block 12 and the guide groove 11 ensures that the locking block 7 can only slide in the set direction, avoiding the problem of the locking block 7 shifting or getting stuck due to external force, improving the accuracy and stability of the locking block 7's movement, and reducing wear between components.

[0027] Preferably, in this embodiment, a guide rod 13 is fixedly installed in the guide groove 11. The guide rod 13 and the guide block 12 are slidably connected. The guide rod 13 provides a clearer and more fixed sliding path for the locking block 7, ensuring that the locking block 7 can only move along the direction of the guide rod 13. Compared with the design that relies solely on the guide groove 11, this design can provide higher guiding accuracy and reduce the offset of the locking block 7 caused by lateral force.

[0028] Preferably, in this embodiment, the guide groove 11, the guide block 12, and the guide rod 13 are all cylindrical. The cylindrical design ensures that the contact surface between the guide block 12 and the guide rod 13 is minimized, thereby reducing the friction between them. Compared with other shapes (such as square or rectangular), the circular surface provides more uniform contact points, which helps to make the sliding smoother.

[0029] Preferably, in this embodiment, the unlocking device includes a rectangular groove 14, a lever 15, and a square groove 16. The mounting block 6 has a rectangular groove 14 at one end away from the filter layer 4. The locking block 7 has a lever 15 that slides with the rectangular groove 14 on its sidewall. The rectangular groove 14 has a square groove 16 at one end away from the lever 15. Before any operation is performed, the locking block 7 is kept in an extended state under the pressure of the spring 10 and is engaged in the locking groove 8 of the mounting groove 5 to ensure that the filter assembly is securely installed. When it is necessary to remove the filter layer 4, the user can manually push it. Two sets of symmetrical levers 15 and square grooves 16 provide space for the hand. Levers 15 slide along rectangular grooves 14 toward square grooves 16, causing locking blocks 7 to retract inward against the pressure of springs 10. As levers 15 move, locking blocks 7 gradually exit from locking grooves 8 until they are completely disengaged from locking grooves 8. At this point, locking blocks 7 are compressed into the storage groove 9, releasing the locking state. The user can easily remove the entire filter assembly from the mounting frame 1. After releasing levers 15, levers 15 and locking blocks 7 return to their original positions under the restoring force of springs 10, ready for the next use.

[0030] Preferably, in this embodiment, slide bars 17 are installed at both the front and rear ends of the filter layer 4, and slide grooves 18 are provided at both the front and rear ends of the groove 3. The slide bars 17 and the slide grooves 18 are slidably connected. When the filter layer 4 is brought close to the opening end of the groove 3, the slide bars 17 are aligned with the inlet of the slide groove 18, and the filter layer 4 is gently pushed in. The slide bars 17 begin to slide along the inner wall of the slide groove 18, guiding the filter layer 4 smoothly into the groove 3. During the pushing process, the tight cooperation between the slide bars 17 and the slide groove 18 ensures that the filter layer 4 will not shift or tilt. When the filter layer 4 is completely pushed into the groove 3, the slide bars 17 reach the end position of the slide groove 18. At this time, the filter layer 4 is correctly installed in place.

[0031] Preferably, in this embodiment, both the slide bar 17 and the slide groove 18 are T-shaped designs. The T-shaped slide bar 17 and the corresponding T-shaped slide groove 18 cooperate to provide a more defined and fixed sliding path, ensuring that the filter layer 4 can only move along the preset direction. Compared with other shapes (such as rectangles or circles), the T-shaped design can provide a better centering effect and prevent the filter layer 4 from shifting or tilting during installation.

[0032] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
