[0021] Specifically, the lower end of the sealing cover 2 is respectively fixedly mounted with a third limiting ring 22 and a fourth limiting ring 23, the first filter plate 8 and the second filter plate 9 are respectively movably mounted in the third limiting ring 22 and the fourth limiting ring 23, the outer wall surfaces of the first filter plate 8 and the second filter plate 9 are respectively fixedly mounted with a first sealing ring 24 and a second sealing ring 25, the third limiting ring 22 and the fourth limiting ring 23 can be used to limit the first filter plate 8 and the second filter plate 9 respectively, to prevent the first filter plate 8 and the second filter plate 9 from deviating, causing internal air leakage, resulting in insufficient air purification, and the first sealing ring 24 and the second sealing ring 25 can strengthen the sealing between the third limiting ring 22 and the fourth limiting ring 23 and the first filter plate 8 and the second filter plate 9;

[0022] Specifically, the lower end of the air purifier cartridge 1 is symmetrically fixed with support legs 26, and the lower end of the support legs 26 is provided with support grooves 27, and a cylinder 28 is fixedly installed in the support grooves 27, and a universal wheel 29 is fixedly installed at the telescopic end of the cylinder 28.

[0023] Specifically, a second air outlet 30 is provided through the middle of the sealing cover 2 and a second exhaust fan 31 is connected to the second air outlet 30 through a thread. The second air inlet 30 can increase the air outlet, improve the air exchange efficiency, and speed up the purification cycle of the air in the respiratory department.

[0024] Specifically, the air inlet 3 is arranged obliquely downward from the inside to the outside, so that the air inlet 3 has a waterproof effect;

[0026] Working principle: When the utility model is in use, an airtight space is formed inside the air purifier cartridge 1 and the sealing cover 2. The sealing gasket 32 ​​can increase the sealing performance between the sealing cover 2 and the air purifier cartridge 1 to prevent air from leaking from the gap. The internal air is extracted by the first exhaust fan 7 to create a negative pressure inside, and the air in the respiratory department is sucked in and purified. The air enters the interior through the air inlet 3. The air inlet 3 is evenly distributed on the side wall of the air purifier cartridge 1. The air inlet 3 is arranged obliquely downward from the inside to the outside, so that the air inlet 3 has a waterproof effect, can inhale the air around, and has a wide purification range.

The air is discharged through the first air outlet 6, and the air outlet end of the air can be increased through the second air inlet 30, so that the air exchange efficiency of the air is improved, and the purification cycle of the air in the respiratory department is accelerated. At the same time, after long-term use, the first filter plate 8 and the second filter plate 9 inside can be disassembled and replaced by unscrewing the sealing cover 2. The replacement is very convenient, which is convenient for maintenance personnel to change. The first filter plate 8 and the second filter plate 9 are fixed in position to prevent the first filter plate 8 and the second filter plate 9 from shaking, which may cause the sealing cover 2 to be loose and further cause air leakage. The third limiting ring 22 and the fourth limiting ring 23 may respectively limit the first filter plate 8 and the second filter plate 9 to prevent the first filter plate 8 and the second filter plate 9 from deviating, which may cause internal air leakage and cause air purification. The sealing between the third limiting ring 22 and the fourth limiting ring 23 and the first filter plate 8 and the second filter plate 9 can be strengthened by the first sealing ring 24 and the second sealing ring 25. A control device is provided outside, and the cylinder 28 can be controlled by the external control device. Then, the height of the universal wheel 29 can be adjusted by the extension and retraction of the telescopic end of the cylinder 28. When the air purification cartridge 1 needs to be shifted, the universal wheel 29 is used for support, which facilitates the shift of the air purification cartridge 1 in the respiratory department. After the shift is completed, the universal wheel 29 can be retracted.
