[0021] Please refer to Figure 3The outer part of the limiting guide 5 is provided with a reset spring 17, and one end of the reset spring 17 is fixedly connected with the outer part of the mounting plate 6. When the motor 15 reversely rotates, the threaded sleeve 12 also starts to reversely rotate. The reverse rotation of the threaded sleeve 12 causes the threaded rod 13 to descend through the threaded connection. The descent of the threaded rod 13 drives the inclined block 11 to move downward in the mounting groove 10 until the inclined surface of the inclined block 11 is no longer in contact with the roller 9. When the inclined surface of the inclined block 11 is disengaged from the roller 9, the roller 9 stops being pushed, and the mounting plate 6 and the limiting block 7 are no longer subjected to the pushing force from the inclined block 11. The reset spring 17 starts to play its role. Since the movement of the roller 9 and the mounting plate 6 causes the reset spring 17 to be compressed, the spring now releases the elastic potential energy stored therein. The reset spring 17 pushes the mounting plate 6 to move along the limiting guide 5 until the mounting plate 6 and the limiting block 7 return to their initial positions, so that the filter element 3 in the mounting frame 4 can be more conveniently taken out and at the same time be prepared for the next installation of the filter element 3.

[0022] Please refer to Figure 2 The inner part of the mounting frame 4 is provided with a plurality of reset springs 18. One end of the reset spring 18 is fixedly provided with a frame body 19, and one side of the frame body 19 can be in contact with the outer part of the filter element 3. The side of the frame body 19 in contact with the filter element 3 is fixedly provided with a sealing rubber pad 2. When the filter element 3 is put into the mounting frame 4, it will compress the reset spring 18, so that the spring stores elastic potential energy. Once the filter element 3 is correctly installed in place, the elastic force released by the reset spring 18 will push the frame body 19 to tightly adhere to the outer part of the filter element 3, thereby ensuring the stability of the filter element 3 during installation. The design of the frame body 19 enables it to closely fit the shape and size of the filter element 3, providing uniform support force. This close fit not only helps to maintain the stability of the filter element 3, but also reduces the deformation of the filter element 3 during installation. The sealing rubber pad 2 is fixed on the side of the frame body 19 in contact with the filter element 3, which is used to provide additional sealing effect. It can prevent air from leaking from the gap between the filter element 3 and the mounting frame 4, thereby improving the overall performance of the filter. When the limiting block 7 returns to the initial position, the combined action of the reset spring 18 and the frame body 19 can push the filter element 3 out of the mounting frame 4, making it more convenient to take out the filter element 3 and reducing the complexity and time cost of manual operation.

[0023] When the staff installs the filter core 3 to the inside of the installation frame 4, the motor 15 starts, the threaded rod 13 rises and drives the inclined block 11 to move in the installation groove 10, when the roller 9 rolls to the inclined surface of the inclined block 11, the rising of the inclined block 11 will push the roller 9 to move along the predetermined path, and through the installation plate 6 drives the limiting block 7 to move to the predetermined position, the limiting block 7 blocks and limits one side of the filter core 3 installed in the installation frame 4, and fixes it to the inside of the installation frame 4, when the motor 15 reverses, the threaded rod 13 descends and drives the inclined block 11 to move downward in the installation groove 10, until the inclined surface of the inclined block 11 is no longer in contact with the roller 9, when the inclined surface of the inclined block 11 is out of contact with the roller 9, the roller 9 stops being pushed, the installation plate 6 and the limiting block 7 are no longer subjected to the thrust from the inclined block 11, the reset spring I 17 begins to play its role, the reset spring I 17 pushes the installation plate 6 to move along the limiting guide 5, until the installation plate 6 and the limiting block 7 return to their initial positions, so that the filter core 3 in the installation frame 4 can be taken out more conveniently, and at the same time, it is ready for the next installation of the filter core 3, so that the installation and disassembly of the filter core 3 can be more convenient, and then the replacement of the filter core 3 becomes simple and fast, when the limiting block 7 returns to the initial position, the combined action of the reset spring II 18 and the frame 19 can push the filter core 3 out of the installation frame 4, so that the filter core 3 is more convenient to take, and the complexity and time cost of manual operation are reduced.

[0024] It is apparent to those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the present application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
