[0029] The technical scheme in the utility model embodiment will be described clearly and completely in combination with the drawings of the utility model embodiment. In the case of no conflict, the following embodiment and the features in the embodiment can be combined with each other.

[0030] This embodiment provides an air purification and sterilization device, such as... Figures 1 to 7 As shown, the device includes a frame 1, a filter element 2, and a discharge assembly 3. The filter element 2 and the discharge assembly 3 are disposed inside the frame 1. The frame 1 includes a first outer frame 10 and a second outer frame 11. The first outer frame 10 and the second outer frame 11 are connected by a snap-fit ​​mechanism. The snap-fit ​​mechanism includes plastic hooks 102 and buckles 112. Multiple plastic hooks 102 and buckles 112 are provided. Multiple plastic hooks 102 are disposed on the inner side wall of the first outer frame 10, and multiple buckles 112 are disposed on the top of the side wall of the second outer frame 11. The multiple plastic hooks 102 and multiple buckles 112 correspond one-to-one. Since the first outer frame 10 and the second outer frame 11 are connected by the snap-fit ​​mechanism, the overall structure of the frame 1 is more stable.

[0031] Furthermore, the discharge assembly 3 includes needle plates 30 and discharge elements 31. Multiple needle plates 30 are arranged along the length of the second outer frame 11 and sequentially along the width of the second outer frame 11. Discharge elements 31 are equidistantly arranged on each needle plate 30. The discharge elements 31 are either tungsten needles or carbon brushes, and all discharge elements 31 on the needle plates 30 face the filter element 2. The discharge assembly 3 is used to connect to an electrode in an external power circuit to discharge the filter element 2. The discharge elements 31 on the needle plates 30 are arranged in multiple rows along the width of the second outer frame 11, with each row of discharge elements 31 arranged laterally along the length of the needle plate 30, so that the discharge elements 31 on the needle plates 30 can cover the filter element 2.

[0032] Furthermore, the discharge assembly 3 is fixedly installed inside the first outer frame 10. Specifically, the first outer frame 10 is provided with a plurality of first mounting seats 101. The discharge assembly 3 is fixedly installed inside the first outer frame 10 through the first mounting seats 101. By fixing the discharge assembly 3 inside the first outer frame 10, the discharge assembly 3 can be firmly fixed in the designated position, ensuring that the discharge assembly 3 will not shift or loosen during operation, thereby improving the stability and reliability of the overall structure.

[0033] Furthermore, filter element 2 comprises a melt-blown layer and an activated carbon fiber skeleton that are stacked and adhered to each other. Using an activated carbon fiber skeleton increases the strength of filter element 2, ensuring it is less prone to deformation or damage during use, thus extending its service life. The activated carbon fiber skeleton also improves the adsorption efficiency of filter element 2. Filter element 2 has a continuously bent structure to increase the contact area between it and the air, thereby improving air filtration and purification efficiency. A manganese-based coating is also applied to the surface of the activated carbon fiber skeleton to further enhance the bactericidal effect and aging resistance of filter element 2.

[0034] Further, the filter element 2 is fixedly arranged in the second outer frame 11, specifically, a plurality of second mounting seats 111 are arranged in the second outer frame 11, and the filter element 2 is fixedly arranged in the second outer frame 11 through the second mounting seats 111. By fixing the filter element 2 in the second outer frame 11, displacement or loosening of the filter element 2 during use is avoided, and the stability and reliability of the overall structure are improved.

[0035] Further, the filter element 2 is fixedly arranged in the second outer frame 11, specifically, a plurality of second mounting seats 111 are arranged in the second outer frame 11, and the filter element 2 is fixedly arranged in the second outer frame 11 through the second mounting seats 111. By fixing the filter element 2 in the second outer frame 11, displacement or loosening of the filter element 2 during use is avoided, and the stability and reliability of the overall structure are improved.

[0036] It should be noted that when the discharge assembly 3 is connected to the positive electrode of the high-voltage pack, the active carbon fiber framework is connected to the negative electrode or ground of the high-voltage pack through the electrical connection piece 4. At this time, the discharge elements 31 arranged on the needle plate 30 release plasma. When the discharge assembly 3 is connected to the negative electrode of the high-voltage pack, the active carbon fiber framework is connected to the ground or positive electrode of the high-voltage pack through the electrical connection piece 4. At this time, the discharge elements 31 arranged on the needle plate 30 release negative ions. Since the discharge elements 31 arranged on the needle plate 30 can more easily release negative ions when the discharge assembly 3 is connected to the negative electrode of the high-voltage pack, it is preferred that the discharge assembly 3 be connected to the negative electrode of the high-voltage pack, and the active carbon fiber framework be connected to the ground or positive electrode through the electrical connection piece 4.

[0037] Wherein, in actual use, two electric fields can be set according to actual needs, specifically, the original filter core 2 is moved upwards and located in the first outer frame 10, the electrically connected sheet 4 connected with the active carbon fiber skeleton is arranged in the first frame, then the insulating column is arranged on the needle plate 30, used for fixing the original filter core 2, and the filter core 2 and the discharge assembly 3 are spaced apart by a certain distance, then a group of discharge assemblies 3 and filter cores 2 are rearranged in the second outer frame 11, and the two filter cores 2 are spaced apart by a certain distance, wherein, the group of rearranged discharge assemblies 3 and filter cores 2 are also fixed on the needle plate 30 by the insulating column and spaced apart by a certain distance, wherein, the discharge element 31 in the newly arranged discharge assembly 3 is arranged towards the filter core 2, and the electrically connected sheet 4 originally located in the second outer frame 11 is electrically connected with the active carbon fiber skeleton in the newly arranged filter core 2, so as to realize two electric fields, and the air purification effect can be further optimized by the configuration of the double electric field, and more efficient particulate matter capture and sterilization function can be provided.
