The tightening block 311 is located between the first fixing plate and the second fixing plate, and the two ends of the tightening block 311 are respectively connected to the top end of the first compression spring 310 and the top end of the second compression spring.

[0045] The fixing mechanism also includes a first vertical rod 309 and a second vertical rod, wherein the first vertical rod 309 is located in the first compression spring groove 310, and the second vertical rod is located in the second compression spring groove. The first compression spring 310 is sleeved on the first vertical rod 309, and the second compression spring is sleeved on the second vertical rod. The two ends of the pressing block 311 are provided with a first perforation and a second perforation. The first vertical rod 309 passes through the first perforation, and the second vertical rod passes through the second perforation. The pressing block 311 moves up and down along the first vertical rod 309 and the second vertical rod. The first vertical rod 309 and the second vertical rod are used to prevent the pressing block 311, the first compression spring 310 and the second compression spring from escaping from the first compression spring groove 308 and the second compression spring groove. When the cover 41 is closed, the pressing block 311 moves downward to compress the compression spring 310. When the cover is opened, the compressed compression spring 310 will return to its original state and lift the filter material to a certain height, making it convenient to take out, replace or clean the filter material.

[0046] The other structures of this embodiment 3 are the same as those of embodiment 1 and will not be described again here.

[0047] To sum up, when the liquid flows through the filter, the utility model filters and collects the larger impurity particles in the liquid through the collection bag, and then further filters it through the HEPA filter, activated carbon plate and fiber non-woven fabric, effectively removing the odor and fine particles in the liquid, and efficiently filtering out impurities in the liquid. After the filtration is completed, the cover is opened by opening the sealing mechanism, and the filter unit is automatically popped out by the pop-up device, which can be easily taken out and cleaned to prevent blockage, which is convenient for users to use, and the filter material can be replaced and can be used multiple times.

[0048] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
