[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] Example: Figure 1-Figure 2As shown, a negative pressure disinfection device with multi-stage filtration and anti-cross infection includes a disinfection box 1, an air inlet 5 is arranged on the left side of the disinfection box 1, a negative pressure fan 24 is arranged on the rightmost end of the disinfection box 1, and an air outlet 8 is arranged on the right side of the negative pressure fan 24. Through the operation of the negative pressure fan 24, polluted air is drawn from the air inlet 5 to the inside of the disinfection box 1 for disinfection and purification, and the disinfected and purified air is discharged from the air outlet 8 to achieve purification and disinfection of the air.

[0027] like Figure 2-Figure 3 - Figure 5 As shown, the switching box 2 is located at the upper end of the disinfection box 1, and a servo motor 9 is installed on the outer side of the rear end of the switching box 2. The driving shaft of the servo motor 9 is set inside the switching box 2 and is connected to the driving wheel 11 at the upper end of the switching box 2. The driving wheel 11 and the driven wheel 12 are sleeved with belts 13 on the outer sides. The moving frames 14 are set on the left and right sides of the belt 13. The moving frames 14 are connected to the belt 13 through connecting plates 16. Slide blocks 15 are set on both sides of the moving frame 14, and two groups of through grooves are set between the lower end of the switching box 2 and the disinfection box. The two groups of slide grooves 10 inside the switching box 2 and the slide grooves 10 inside the disinfection box 1 are located in the same straight line, and the slide blocks on the left and right sides of the moving frame 14 are The filter cloth 27 is slidably mounted inside the slide groove 10. When the filter cloth 27 needs to be replaced, the servo motor 9 is operated to drive the driving wheel 11 to rotate, thereby rotating the outer belt 13. Since the belt 13 is fixed to one side of the movable frame 14, the left and right movable frames are driven to interchange positions, so that the filter cloth 27 that needs to be replaced is moved to the inside of the switching box 2, so that the filter cloth can be replaced without opening the disinfection box 1, and the normal operation of the disinfection box 1 will not be interrupted. At the same time, the chance of contact with the disinfectant can be reduced, the risk of cross infection can be reduced, and the filter cloth with too many impurities can be prevented from reducing the working efficiency of the disinfection box. At the same time, the movable frame 14 and the filter cloth 27 are fixed by studs to improve the convenience of operation.

[0028] like Figure 3 As shown, the ozone generator 3 at the upper end of the disinfection box 1 is connected to the nozzle 19 through the conduit 18, and the negative pressure fan 24 is running. When the polluted air inlet 5 is drawn into the interior of the disinfection box, it is first filtered through the filter cloth 27, and the filter cloth 27 can filter dust, impurities, etc., and then disinfected with ozone through the nozzle. After disinfection, it passes through the activated carbon mesh plate 20, the primary filter 21, the high-efficiency filter 22, and the photothermal synergistic photocatalyst mesh 23 in sequence for filtration to further remove ozone and other pathogenic microorganisms. Layered and multi-stage filtration can also increase the service life of air treatment equipment. Filters at different levels perform their respective functions, which can reduce the pressure on each filter, reduce the loss and wear of the filter, and improve the air purification effect.

[0029] like Figure 4As shown, a mounting frame 4 is fixedly provided on the left side of the disinfection box 1, and mounting seats 25 are provided at the four inner corners of the mounting frame 4. The air inlet 5 is movably installed inside the mounting frame 4, and the rear end of the air inlet 5 is fixedly provided with a mounting plug 26, and the mounting plug 26 fits into the mounting seat 25. After the air inlet 5 is installed in the mounting frame 4, the outer side of the air inlet 5 is fixed by rotating the rotating baffles 6 at the upper and lower ends of the mounting frame 4. After long-term use, when the air inlet 5 needs to be cleaned, the rotating baffle 6 can be rotated upwards and the air inlet 5 can be disassembled for cleaning to prevent dust from affecting the air flow of the air inlet 5.

[0030] Working principle: When in use, the negative pressure fan 24 is operated to draw the polluted air from the air inlet 5 to the inside of the disinfection box, and the air is first filtered through the filter cloth 27, which can filter dust, impurities, etc., and then disinfected with ozone through the nozzle. After disinfection, the air is filtered through the activated carbon screen 20, the primary filter 21, the high-efficiency filter 22, and the photothermal synergistic photocatalyst screen 23 in sequence. When the filter cloth 27 needs to be replaced, the servo motor 9 is operated to drive the driving wheel 11 to rotate, thereby rotating the outer belt 13. Since the belt 13 is fixed to one side of the moving frame 14, the left and right moving frames are driven to rotate. The positions are interchanged so that the filter cloth 27 that needs to be replaced can be moved to the inside of the switching box 2, so that the filter cloth can be replaced without opening the disinfection box 1, and the normal operation of the disinfection box 1 will not be interrupted. At the same time, the chance of contact with the disinfectant can be reduced, the risk of cross infection can be reduced, and the filter cloth with too many impurities can be prevented from reducing the working efficiency of the disinfection box. At the same time, the movable frame 14 and the filter cloth 27 are fixed by studs to improve the convenience of operation. After long-term use, when the air inlet 5 needs to be cleaned, the rotating baffle 6 can be turned upward and the air inlet 5 can be disassembled for cleaning to prevent dust from affecting the air flow of the air inlet 5.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
