[0025] The outer frame 1 is fixedly connected with the shell 2 on both sides, the shell 2 is fixedly connected on both sides of the outer frame 1, used for accommodating and protecting the bidirectional screw rod 7, the screw sleeve 8 and other components, and providing operation space, the inner cavity of the shell 2 is vertically provided with the bidirectional screw rod 7, the bidirectional screw rod 7 is vertically arranged in the inner cavity of the shell 2, and can drive the screw sleeve 8 to move synchronously by rotating, but the moving direction is opposite. The design of the bidirectional screw rod 7 makes the disassembly and installation process of the filter material 3 more convenient, the outer circle of the bidirectional screw rod 7 is sleeved with the screw sleeve 8 on both sides, the screw sleeve 8 is sleeved on both sides of the outer circle of the bidirectional screw rod 7 and is in threaded connection with the bidirectional screw rod 7. When the bidirectional screw rod 7 rotates, the screw sleeve 8 will move with it and drive the insertion rod 11 to move through the connecting block 12, the both sides of the outer wall of the outer frame 1 are provided with the through groove 9 on both sides, the through groove 9 is provided on both sides of the outer wall of the outer frame 1 and is communicated with the inner cavity of the clamping groove 6. The through groove 9 provides a moving channel for the connecting block 12 and the insertion rod 11, ensures that they can stably move and be inserted or pulled out of the insertion hole 5, and the inner cavity of the through groove 9 is communicated with the inner cavity of the corresponding clamping groove 6, the outer circle of the screw sleeve 8 is fixedly connected with the connecting block 12 penetrating through the corresponding through groove 9, and the connecting block 12 is fixedly connected on the outer circle of the screw sleeve 8 and penetrates through the through groove 9. The bottom of the connecting block 12 is fixedly connected with the insertion rod 11, used for transmitting the movement of the screw sleeve 8 to the insertion rod 11 and realizing the insertion or pulling out of the insertion rod 11 and the insertion hole 5, and the bottom of the connecting block 12 is fixedly connected with the insertion rod 11, the insertion rod 11 is fixedly connected at the bottom of the connecting block 12 and is used for being inserted or pulled out of the insertion hole 5, forming or releasing the fastening force, so as to realize the quick disassembly and installation of the filter material 3.

[0026] Further, the insertion rod 11 is inserted into the corresponding insertion hole 5, and the insertion rod 11 is inserted into the corresponding insertion hole 5. Through the arrangement that the insertion rod 11 is inserted into the corresponding insertion hole 5: when installing the filter material 3, the insertion rod 11 is accurately inserted into the insertion hole 5, forming a stable fastening force, ensuring that the filter material 3 is firmly fixed in the outer frame 1 and will not move or fall off due to airflow or external force. When disassembling the filter material 3, only need to rotate the bidirectional screw rod 7 to pull out the insertion rod 11 from the insertion hole 5, so as to easily release the fastening force and realize the quick disassembly of the filter material 3. This arrangement significantly improves the efficiency and stability of the installation and disassembly of the filter material 3, and reduces the maintenance difficulty.

[0027] Further, the outer circle of the connecting block 12 is in sliding connection with the inner cavity of the corresponding through groove 9, and the outer circle of the connecting block 12 is in sliding connection with the inner cavity of the corresponding through groove 9. Through the arrangement that the outer circle of the connecting block 12 is in sliding connection with the inner cavity of the corresponding through groove 9: the connecting block 12 serves as a transmission bridge between the screw sleeve 8 and the insertion rod 11, and the sliding connection between the outer circle of the connecting block 12 and the through groove 9 ensures that the insertion rod 11 can stably move along the through groove 9 and will not deviate from the track due to external force. This arrangement ensures the smoothness of the disassembly and installation process of the filter material 3, and avoids the operation difficulty caused by jamming or deviation.

[0028] Further, the two ends of the bidirectional screw rod 7 are respectively connected with the inner wall of the adjacent shell 2 through the rotating shaft, and the two ends of the bidirectional screw rod 7 are respectively connected with the inner wall of the adjacent shell 2 through the rotating shaft. The setting that the two ends of the bidirectional screw rod 7 are connected with the inner wall of the adjacent shell 2 through the rotating shaft ensures that the bidirectional screw rod 7 can stably transmit power to the screw sleeve 8 when rotating, thereby driving the plug rod 11 to move. This setting ensures the reliability and stability of the disassembly and assembly process of the filter material 3, and improves the operation efficiency.

[0029] Further, the middle part of the outer ring of the bidirectional screw rod 7 is fixedly connected with the rubber anti-skid handle 10. The setting that the middle part of the outer ring of the bidirectional screw rod 7 is fixedly connected with the rubber anti-skid handle 10 provides the user with a comfortable holding feeling and good anti-skid performance, so that the force can be applied more easily and stably when rotating the bidirectional screw rod 7. This setting improves the convenience and safety of operation, and reduces the operation errors caused by slipping or unstable holding.

[0030] Further, the two bidirectional screw rods 7 are symmetrically distributed on the two sides of the outer frame 1. The setting that the two bidirectional screw rods 7 are symmetrically distributed ensures that the filter material 3 is uniformly stressed during disassembly and assembly, and will not be damaged or deformed due to excessive unilateral stress. This setting ensures the integrity and service life of the filter material 3, and improves the overall performance and stability of the air purification system.

[0031] In summary: when the filter material 3 needs to be replaced, the user first holds the rubber anti-skid handle 10 and rotates the bidirectional screw rod 7. Since the two ends of the bidirectional screw rod 7 are connected with the outer shell 2 through the rotating shaft, the rotation of the bidirectional screw rod 7 will drive the screw sleeves 8 on the two sides of the outer ring to move synchronously, but in opposite directions. The movement of the screw sleeves 8 is transmitted to the plug rod 11 through the connecting block 12. Since the connecting block 12 is connected with the through groove 9 in a sliding manner, it ensures that the plug rod 11 can stably move along the through groove 9. When the plug rod 11 is pulled out of the insertion hole 5, the fastening force formed by the cooperation of the plug rod 11 and the insertion hole 5 disappears, and the plug-in relationship between the clamping block 4 and the clamping groove 6 is released. The user can easily pull out the filter material 3 together with the clamping block 4 from the outer frame 1, and complete the disassembly of the filter material 3. When replacing the new filter material 3, only need to insert the clamping block 4 of the new filter material 3 into the clamping groove 6, and rotate the bidirectional screw rod 7 in the opposite direction, so that the plug rod 11 is reinserted into the insertion hole 5, and the installation of the filter material 3 is completed.

[0032] Advantages:

[0033] Simplify disassembly process: through the cooperation of the bidirectional screw rod 7 and the screw sleeve 8, and the plug-in design of the plug rod 11 and the insertion hole 5, the filter material 3 is quickly disassembled and installed, without the need to disassemble multiple fastening components, greatly reducing the operation complexity and reducing the work burden of the user. Improve maintenance efficiency: due to the simplified filter material 3 replacement process, the user can complete the maintenance work more quickly, thereby improving the overall maintenance efficiency of the air purification system. Reduce maintenance cost: the simplified disassembly design reduces the potential damage risk to other components of the filter caused by complex operation, thereby reducing the maintenance cost. Improve user experience: the convenient filter material 3 replacement process enables the user to more easily maintain the filter, thereby improving the user experience.
