[0025] Embodiment 2

[0026] See also Figure 1-2 5. A limit plate 18 is fixedly installed on the top of the mounting block B5, and a limit groove 19 is provided inside the limit plate 18. A mounting card 20 is fixedly installed on the bottom end of the filter screen 6, and a soft pad 21 is fixedly installed on the top of the mounting card 20. A pull rod 22 is fixedly installed on the top of the mounting card 20, which makes it more convenient to replace the filter screen 6. When it needs to be replaced after long-term use, the pull rod 22 can be pulled backward to make the mounting card 20 drive the soft pad 21 to slide out of the interior of the limit plate 18 through the limit groove 19, and then the new filter screen 6 is corresponding to the upper limit groove 19 and pushed inward, so that the mounting card 20 can slide into the interior of the limit plate 18 through the limit groove 19, so that the soft pad 21 can be replaced. The filter screen 6 is firmly fixed by installing the card plate 20, thereby preventing the situation where the filter screen 6 needs to be replaced later and needs to be disassembled with the help of tools. The limit plates 18 are symmetrically distributed at the upper and lower ends of the mounting block B5 and the mounting block A4, and the mounting card plates 20 are slidingly connected to the limit plates 18. The mounting card plates 20 are symmetrically distributed at the upper and lower ends of the filter screen 6, and the soft pads 21 are symmetrically distributed at the left and right ends of the top of the mounting card plates 20. The soft pads 21 are slidingly connected to the limit plates 18, which makes it easier for the mounting card plates 20 to slide, and avoids the situation where the mounting card plates 20 are stuck by the limit plates 18 or the mounting blocks A4 and B5 during use, causing the mounting card plates 20 to be unable to continue sliding.

[0027] Working principle: When in use, first place the purifier body 1 at the required position, then let the external air float into the interior of the purifier body 1 through the dustproof plate 12, and filter through the filter screen 6 between the mounting block B5 and the mounting block A4, and finally float out of the interior of the purifier body 1 through the protective net 3 and the exhaust port 2. After long-term use, when cleaning is needed, you can pinch the handle 17 and rotate it, so that the threaded rod 16 rotates backward inside the purifier body 1 through the rotating groove 15. When the threaded rod 16 passes through the rotating groove 15, the threaded rod 16 rotates backward inside the purifier body 1. After the rotating groove 15 is completely rotated out of the interior of the purifier body 1, it can be taken out from the interior of the fixing plate 13 through the fixing groove 14, and then the mounting plate 11 is pinched and pulled backward to rotate the mounting plate 11 backward on the surface of the purifier body 1. When the mounting plate 11 is completely rotated out of the interior of the purifier body 1, it is pulled upward to slide the card block 10 out from between the baffle plate 9 and the protrusion 7. At this time, the dust plate 12 can be cleaned, and the pull rod 22 can be pinched and pulled backward to slide the mounting card plate 20 out of the inner of the limiting plate 18 through the limiting groove 19. The filter 6 is then replaced. When the filter 6 is replaced, the mounting card plate 20 is again aligned with the upper limit slot 19 and pushed forward so that the mounting card plate 20 slides into the interior of the limit plate 18 through the limit slot 19. When the mounting card plate 20 completely slides into the interior of the limit plate 18, the cushion 21 can firmly clamp the mounting card plate 20 in the interior of the limit plate 18. Then, the card block 10 is aligned between the upper baffle plate 9 and the protrusion 7 and pressed downward, so that the card block 10 slides into between the baffle plate 9 and the protrusion 7 and then pushed backward to make the mounting card plate 20 slide into the interior of the limit plate 18. The plate 11 slides into the interior of the purifier body 1, and the back of the mounting plate 11 contacts the sealing gasket 8 on the surface of the protrusion 7. At this time, the turning handle 17 is pinched to match the threaded rod 16 to the rotating groove 15 and rotate it. After the threaded rod 16 is completely rotated into the interior of the purifier body 1 through the rotating groove 15, the threaded rod 16 can pass through the fixing groove 14 and the fixing plate 13 to firmly fix the mounting plate 11 on the surface of the purifier body 1, and at this time, the sealing gasket 8 is firmly stuck between the mounting plate 11 and the protrusion 7, thereby improving its sealing effect.
