Air cleanliness is one of the important factors in ensuring the quality of facial masks. Traditional air purifiers typically use fans to draw air into the purifier and then filter polluted air through built-in filters. However, the filter structure of traditional air purifiers is relatively simple, and they can only filter dust, odors, and toxic gases. Some filters can even kill some bacteria, but for the high cleanliness requirements of facial mask production workshops and the quality of facial mask production, traditional air purifiers still have the drawback of poor filtration effect and cannot meet the high cleanliness requirements.

[0037] like Figures 1-4 As shown, this utility model provides an air filtration device for a mask production workshop, including a filter cylinder 10 and a top cover 20. The filter cylinder 10 has an opening at one end along the axial direction, and the top cover 20 is connected to the filter cylinder 10 and seals the opening.

[0038] In a specific embodiment, the filter cylinder 10 has an air inlet 11 on the side wall near the opening and an air outlet 12 on the side away from the opening. By placing the air inlet 11 and the air outlet 12 at opposite ends of the filter cylinder 10, the air flow path within the filter cylinder 10 can be effectively extended, thereby improving the filtration effect. Outside air is delivered to the air inlet 11 through the air inlet pipe 30, and the filtered gas is discharged from the air outlet 12 and delivered to a specific workshop through the air outlet pipe 40.

[0039] In some embodiments, the filter cartridge 10 has a first chamber 101 inside. The first chamber 101, from the air inlet 11 to the air outlet 12, is sequentially equipped with a first filter screen 103, an ultraviolet lamp 106, a multi-stage purification filtration module 109, and a negative ion generator 111. The ultraviolet lamp 106 is arranged circumferentially on the inner wall of the filter cartridge 10. The inner wall of the filter cartridge 10 is axially provided with spaced first limiting rings 107 and second limiting rings 108. The multi-stage purification filtration module 109 is disposed between the first limiting rings 107 and the second limiting rings 108. The negative ion generator 111 is installed on the inner wall of the filter cartridge 10. The first filter 103, located between the air inlet 11 and the air outlet 12, removes most of the dust. After being irradiated by the ultraviolet lamp 106, some bacteria are killed. Then, the multi-stage purification filter module 109 can remove dust, sterilize, and adsorb odors and toxic gases, thereby improving the filtration effect to meet the high cleanliness requirements of the mask production workshop. Finally, the negative ion generator 111 continuously ionizes the air to generate a large number of negative ions, which enhances the purpose of cleaning and purifying the air. The air with negative ions is delivered to the mask production workshop through the air outlet 12 to ensure the high cleanliness requirements of the workshop.

[0040] Specifically, from the air inlet 11 to the air outlet 12, the multi-stage purification and filtration module 109 sequentially includes a third filter 1901, an activated carbon adsorption layer 1902, a manganese oxide filter layer 1903, a photocatalyst filter layer 1904, and a graphene filter layer 1905. The third filter 1901 abuts against the first limiting ring 107, the graphene filter layer 1905 abuts against the second limiting ring 108, and the ultraviolet lamp 106 is located between the first filter 103 and the third filter 1901. Thus, the third filter 1901 can further filter dust in the air, the activated carbon adsorption layer 1902 can effectively adsorb odors and toxic gases, the manganese oxide filter layer 1903 can catalytically decompose and adsorb formaldehyde and volatile organic compounds (TVOC), while the photocatalytic filter layer 1904 can further decompose and adsorb formaldehyde and volatile organic compounds (TVOC), and at the same time destroy the bacterial cell wall and viral protein structure to achieve efficient sterilization. The graphene filter layer 1905 uses a porous structure to physically adsorb small molecule gases such as formaldehyde and benzene. In this way, after the air passes through the multi-stage purification filter module 109, it can achieve dust removal, sterilization, adsorption of odors and toxic gases, thereby improving the filtration effect to meet the high cleanliness requirements of the mask production workshop.

[0041] In some embodiments, the activated carbon adsorption layer 1902, the manganese oxide filter layer 1903, the photocatalyst filter layer 1904, and the graphene filter layer 1905 are all porous structures, which can increase the air contact area and improve the filtration effect on the one hand, and increase the air throughput on the other hand, thereby improving the air filtration efficiency.

[0042] In some embodiments, to facilitate the disassembly and replacement of the multi-stage purification and filtration module 109, the first limiting ring 107 is detachably connected to the inner wall of the filter cylinder 10, so that the limiting of the multi-stage purification and filtration module 109 can be released by removing the first limiting ring 107, thereby removing the multi-stage purification and filtration module 109.

[0043] In other embodiments, an openable window may be provided on the wall of the filter cartridge 10 to facilitate the replacement of the multi-stage purification filter module 109.

[0044] In some embodiments, the first filter 103 has a mesh size of 20-60, which can filter large particles in the air and prevent large particles from clogging the third filter 1901.

[0045] In some embodiments, the third filter 1901 has a mesh size of 200-800 mesh, which can filter small particulate matter in the air and prevent particulate matter from accumulating in the activated carbon adsorption layer 1902, manganese oxide filter layer 1903, photocatalyst filter layer 1904 or graphene filter layer 1905 and reducing the filtration effect.

[0046] In some embodiments, a perforated frame 113 is also provided in the first chamber 101. The perforated frame 113 is located at one end of the multi-stage purification and filtration module 109 near the air outlet 12. A third chamber 110 is formed between the perforated frame 113 and the multi-stage purification and filtration module 109. A negative ion generator 111 is disposed in the third chamber 110. The perforated frame 113 is mounted on a fan 114. The fan 114 is configured to push the gas in the third chamber 110 to the air outlet 12. The air in the third chamber 110 is discharged through the air outlet 12 by the fan 114, so that the third chamber 110 is in a negative pressure state, so as to promote the entry of outside air into the filter cartridge 10 and through the multi-stage purification and filtration module 109, thereby improving the air filtration efficiency.

[0047] In some embodiments, the third chamber 110 is provided with a plurality of baffles 112, which are arranged at intervals along the axial direction and are alternately arranged on the inner wall of the filter cartridge 10 to form a meandering flow channel. The negative ion generator 111 is located in the meandering flow channel, thereby extending the airflow path in the third chamber 110 and ensuring that the air can fully contact the negative ions generated by the negative ion generator 111 ionizing the air, thereby improving the effect of cleaning and purifying the air.

[0048] In some implementations, such as Figure 5 As shown, the baffle 112 is inclined, which can guide the airflow to flow downwards and further reduce the air velocity, so that the air can fully contact the negative ions when passing through the meandering channel, thereby improving the filtration and sterilization effect.

[0049] In other embodiments, an air compressor is provided at the end of the air intake pipe 30 away from the air intake port 11. The air compressor pressurizes the outside air and delivers it to the filter cartridge 10 through the air intake pipe 30, thereby further improving the air filtration effect.

[0050] In some embodiments, the top cover 20 is provided with a connecting pipe 21, which is connected to the first chamber 101. The connecting pipe 21 is equipped with a pressure gauge 22 and a pressure relief valve 23. The pressure gauge 22 can monitor the pressure inside the filter cartridge 10 in real time. The pressure relief valve 23 is configured to open and release pressure when the pressure inside the filter cartridge 10 is greater than a set threshold, so as to avoid excessive air pressure inside the filter cartridge 10. The pressure relief valve 23 is connected to the outside through a pipeline to prevent unfiltered air from entering the workshop.

[0051] In some embodiments, a second filter 104 is provided at one end of the first chamber 101 near the top cover 20. The second filter 104 and the first filter 103 are spaced apart along the axial direction, and a second chamber 102 is formed between the second filter 104 and the first filter 103. The air inlet 11 is connected to the second chamber 102. The second filter 104 can block large particles in the air and prevent them from entering the pressure gauge 22 and the pressure relief valve 23 through the connecting pipe 21 and causing blockage.

[0052] In some embodiments, filter cotton 105 is filled between the second filter screen 104 and the top cover 20. The filter cotton 105 can block small particles from entering the pressure gauge 22 and the pressure relief valve 23, thus preventing blockage from affecting the normal use of the pressure gauge 22 and the pressure relief valve 23.

[0053] In some embodiments, a support 50 is provided at the end of the filter cartridge 10 away from the opening. The support 50 is connected to the outer wall of the filter cartridge 10, and the plane at the lowest point of the support 50 is lower than the plane at the air outlet 12, thereby raising the air outlet 12 and creating a certain space between the air outlet 12 and the ground, which facilitates the installation of the air outlet pipe 40.

[0054] The working process of this utility model is as follows: Please refer to... Figures 1-5 When outside air enters the second chamber 102 through the air inlet pipe 30 and the air inlet 11, the air passes through the first filter 103 to remove most of the dust, and then is irradiated by the ultraviolet lamp 106 to kill some bacteria. Then, through the multi-stage purification filtration module 109, dust removal, sterilization, odor adsorption, and toxic gas adsorption can be achieved. Specifically, the third filter 1901 can further filter the dust in the air, the activated carbon adsorption layer 1902 can effectively adsorb odors and toxic gases, the manganese oxide filter layer 1903 can catalytically decompose and adsorb formaldehyde and volatile organic compounds (TVOC), while the photocatalytic filter layer 1904 can further decompose and adsorb formaldehyde and volatile organic compounds (TVOC), and at the same time, it can destroy the bacterial cell wall and viral protein structure to achieve efficient sterilization. The graphene filter layer 1905 uses a porous structure to physically adsorb small molecule gases such as formaldehyde and benzene, thereby improving the filtration effect to meet the high cleanliness requirements of the mask production workshop.

[0055] After being filtered by the multi-stage purification and filtration module 109, the air enters the third chamber 110 and flows along the meandering channel under the action of the baffle 112. The negative ion generator 111 can ionize the air to generate negative ions, which are further mixed with the air to improve the effect of cleaning and purifying the air.

[0056] The filtered gas is discharged from the outlet 12 by the fan 114 and transported to a specific workshop through the outlet pipe 40.

[0057] In summary, the air filtration device for a mask production workshop provided by this utility model effectively extends the airflow path within the filter cylinder 10 by placing the air inlet 11 and the air outlet 12 at opposite ends of the filter cylinder 10. A first filter screen 103, located in the first chamber 101 between the air inlet 11 and the air outlet 12, removes most of the dust. After irradiation by the ultraviolet lamp 106, some bacteria are killed. Then, the air passes through a multi-stage purification filtration module 109. Specifically, a third filter screen 1901 further filters dust from the air, an activated carbon adsorption layer 1902 effectively adsorbs odors and toxic gases, and a manganese oxide filter layer 1903 catalytically decomposes and adsorbs formaldehyde and volatile organic compounds (TVOC). The photocatalytic filter layer 1904 can further decompose and adsorb formaldehyde and volatile organic compounds (TVOC), while destroying bacterial cell walls and viral protein structures to achieve efficient sterilization. The graphene filter layer 1905 uses a porous structure to physically adsorb small molecule gases such as formaldehyde and benzene. Thus, after the air passes through the multi-stage purification filter module 109, it can achieve dust removal, sterilization, adsorption of odors and toxic gases, thereby improving the filtration effect to meet the high cleanliness requirements of the mask production workshop. Finally, the negative ion generator 111 continuously ionizes the air to generate a large number of negative ions, using negative ions to enhance the purpose of cleaning and purifying the air. The air with negative ions is delivered to the mask production workshop through the air outlet 12 to ensure the high cleanliness requirements of the workshop.
