[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] A cleanroom air purification device includes a purifier body 1, a filter plate 2 inserted into the middle of the front end of the purifier body 1, and an air outlet mechanism 3 provided at the rear end of the purifier body 1. The air outlet mechanism 3 includes a fixed frame 31 and an adjusting plate 32. The fixed frame 31 is fixedly inserted into the middle of the rear end of the purifier body 1, and several adjusting plates 32 are evenly rotated and connected to the middle of the fixed frame 31. External air enters the interior of the purifier body 1 through the filter plate 2, and after filtration, it is blown out from the gaps between the adjusting plates 32. The adjusting plates 32 can be rotated on the fixed frame 31 to adjust the air blowing direction.

[0040] The front end of the purifier body 1 is equipped with a disinfection mechanism 4. The disinfection mechanism 4 includes a liquid storage tank 41 fixedly connected to the lower front side of the purifier body 1. Connecting pipes 42 are inserted into both ends of the liquid storage tank 41. Several evenly distributed atomizing nozzles 43 are inserted into the side of the connecting pipes 42 that are close to each other. The upper and lower ends of the connecting pipes 42 are fitted with buckles 44, which are fixedly connected to the inner side wall of the purifier body 1. A liquid supply mechanism 5 is provided on the liquid storage tank 41. The liquid supply mechanism 5 includes a water pump 51, a liquid filling pipe 52, and a pipe cap 53. Two water pumps 51 are fixedly connected to both ends of the liquid storage tank 41. One end of the water pump 51 is connected to the connecting pipe 42. The liquid filling pipe 52 is inserted into the upper side of the liquid storage tank 41. The pipe cap 53 is threadedly connected to the end of the liquid filling pipe 52 that passes through the purifier body 1.

[0041] Unscrew the cap 53 and add air disinfectant to the storage tank 41 through the liquid filling pipe 52. The water pump 51 draws the disinfectant and transmits it through the connecting pipe 42 to the atomizing nozzle 43. The atomized nozzle 43 sprays the disinfectant to sterilize and disinfect the air that has just entered the purifier body 1.

[0042] The purifier body 1 has a filter mechanism 6 in the middle. The filter mechanism 6 includes a pre-filter 61, a medium-efficiency filter 62, and a high-efficiency filter 63 arranged from front to back inside the purifier body 1. The air entering the purifier body 1 passes through the pre-filter 61, the medium-efficiency filter 62, and the high-efficiency filter 63 in sequence to filter and purify the air.

[0043] The sliding mechanism 7 is located inside the purifier body 1. The sliding mechanism 7 includes sliding frames 71 respectively located on the outside of the pre-filter 61, the medium-efficiency filter 62, and the high-efficiency filter 63. The sliding frames 71 are inserted into one side of the purifier body 1. The side of the purifier body 1 has a slot 72 for use with the sliding frames 71. The upper and lower ends of the sliding frames 71 are provided with limit seats 73. The limit seats 73 are fixedly connected to the inside of the purifier body 1. Several evenly distributed balls 74 are rolled on the inner side of the limit seats 73. The balls 74 are rolled on the sliding frames 71. A handle 75 is fixedly connected to the middle of one side of the sliding frames 71. Pulling the handle 75 can pull the sliding frames 71 to slide left and right in the middle of the limit seats 73.

[0044] A limiting mechanism 8 is provided on the sliding frame 71. The limiting mechanism 8 includes an elastic plate 81 fixedly connected to the middle of one end of the front and rear sides of the sliding frame 71. One end of the elastic plate 81 is L-shaped and curved to facilitate pressing by the operator. A retaining plate 82 is fixedly connected to one side of the elastic plate 81. The retaining plate 82 is a triangular plate structure. A retaining groove 83 is provided on one side of the purifier body 1 to cooperate with the retaining plate 82. Pressing the elastic plates 81 on both sides towards the middle can drive the retaining plate 82 to disengage from the retaining groove 83, thereby pulling the sliding frame 71 out of the purifier body 1, which facilitates the replacement of the primary filter 61, medium-efficiency filter 62, and high-efficiency filter 63 on the sliding frame 71.

[0045] The air purifier body 1 has a fixed base 9 at the rear end inside, and a fan 10 is fixedly connected to the middle of the inner side of the fixed base 9.

[0046] In specific implementation of this utility model, such as Figures 1-9 As shown, when in use, unscrew the cap 53 and add air disinfectant to the storage tank 41 through the liquid filling pipe 52. Start the fan 10 to draw outside air into the purifier body 1. The air entering the purifier body 1 passes through the primary filter 61, the medium-efficiency filter 62, and the high-efficiency filter 63 in sequence to filter and purify the air. Then, it is blown out through the gap between the adjustment plates 32. The adjustment plates 32 can be rotated on the fixed frame 31 to adjust the blowing direction.

[0047] The water pump 51 is turned on at regular intervals to draw disinfectant, which is then transmitted through the connecting pipe 42 to the atomizing nozzle 43. The disinfectant is atomized and sprayed out by the atomizing nozzle 43 to sterilize and disinfect the air that has just entered the purifier body 1. The atomized disinfectant is carried backward by the air and adsorbed onto the primary filter 61, which can prevent the accumulation of impurities and the growth of bacteria. The disinfected air is then filtered through the medium-efficiency filter 62 and the high-efficiency filter 63, which can improve the air quality blown out from the purifier body 1.

[0048] When it is necessary to replace the pre-filter 61, medium-efficiency filter 62, and high-efficiency filter 63, press the elastic plates 81 on both sides towards the center. This will cause the retaining plate 82 to disengage from the retaining groove 83, thereby allowing the sliding frame 71 to be pulled out from inside the purifier body 1. This makes it easy to replace the pre-filter 61, medium-efficiency filter 62, and high-efficiency filter 63 on the sliding frame 71.

[0049] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power.
