[0029] Two limiting frames 23 are provided on the inner side of each connecting seat 21 , and the two limiting frames 23 are symmetrically arranged.

[0030] The box shell 1 is provided with a box door 6, and the box door 6 is provided with a plum-shaped hand screw 5. The plum-shaped hand screw 5 is threadedly connected to the threaded hole 4 provided on the box shell 1, which is convenient for disassembly to clean or replace the internal components. The combination mechanism 2 and the installation mechanism 3 are both provided with several groups to realize the installation of multiple filter media.

[0031] Example 2

[0032] On the basis of Example 1, a mounting mechanism 3 is installed on the combination mechanism 2, and the mounting mechanism 3 includes a mounting frame 31 slidably connected to the connecting seat 21, and a spiral spring 32 is arranged inside the mounting frame 31. One end of the spiral spring 32 is fixedly connected to the mounting frame 31, and the other end of the spiral spring 32 is fixedly connected to a connecting shaft 33, and the connecting shaft 33 is rotatably connected to the mounting frame 31, and a limiting block 34 is fixedly connected to the connecting shaft 33.

[0033] The mounting mechanism 3 also includes a slide rail 35 fixedly connected to the mounting frame 31, and a No. 3 spring 37 is provided on the inner side of the slide rail 35, one end of the No. 3 spring 37 is fixedly connected to the slide rail 35, and the other end of the No. 3 spring 37 is fixedly connected to the block 36, and the block 36 is slidably connected to the inner side of the slide rail 35, and a fixing block 39 is provided below the block 36, and the fixing block 39 is fixedly connected to the limit block 34, and the block 36 is slidably connected to the fixing block 39, and the block 36 is fixedly connected to the driving block 38.

[0034] The mounting frame 31 is disposed between the two limiting frames 23 .

[0035] Working principle: First, the staff pulls up the driving block 38 to drive the card block 36 to slide upward and disengage from the inside of the fixed block 39, and the No. 3 spring 37 is compressed. Then, the connecting shaft 33 is rotated by rotating the driving block 38 outward, and the limit block 34 is rotated outward around the connecting shaft 33. The vortex spring 32 is stretched and stores force. Then, the prepared filter cotton or filter screen and other filter media are placed on the mounting frame 31. Then, the driving block 38 is slowly released and the filter cotton or filter screen and other filter media are limited and fixed between the mounting frame 31 and the limit block 34 under the elastic potential energy of the vortex spring 32. The card block 36 is pushed into the inside of the fixed block 39 again through the No. 3 spring 37 to complete the installation of the filter cotton or filter screen. There is no need to use glue or bolts and other fasteners to install the filter cotton, which simplifies the steps of replacing the filter cotton or filter screen and does not require the use of additional tools. The second spring 24 is compressed until the mounting frame 31 is completely slid in. Under the action of the elastic force of the second spring 24, the wedge block 25 is bounced up and the mounting frame 31 is completely stuck in the inside of the connecting seat 21. If disassembly is required, press the pressure block 27 to drive the L-shaped connecting rod 26 to slide. The L-shaped connecting rod 26 drives the wedge block 25 to be retracted into the inside of the connecting seat 21 again, and the mounting frame 31 driving the filter cotton or filter screen can be pulled out from the connecting seat 21. Finally, the box door 6 can be closed on the box shell 1 by rotating the plum hand screw 5.
