Description

Technical Field

[0001] This application relates to the field of air purification and filtration technology, specifically to an antibacterial medium-efficiency filter cotton nanofiber composite filter. Background Technology

[0002] Air purification and filtration refers to the process of removing harmful substances such as particulate matter, gaseous pollutants, bacteria, and viruses from the air through specific technologies and methods, thereby improving air quality and ensuring people's health and the comfort of their living environment. Currently, air purification and filtration technologies have been widely researched and applied.

[0003] Traditional filter materials mainly include HEPA filters and activated carbon filters. Although these materials have high filtration efficiency, they are significantly lacking in antibacterial properties, which may lead to the growth of viruses and bacteria, and there is room for improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an antibacterial medium-efficiency filter made of nanofiber nanofiber, which has the advantages of significantly improving the antibacterial performance of the filter, effectively inhibiting the growth of bacteria and viruses, and reducing the risk of secondary pollution, thus solving the problem of insufficient antibacterial performance of traditional filter materials.

[0005] To achieve the above objectives, this application provides the following technical solution: an antibacterial medium-efficiency filter cotton nanofiber composite filter, comprising a filter layer, a first outer shell, and a second outer shell. The filter layer includes a protective layer, a support layer on the right side of the protective layer, and an antibacterial layer on the right side of the support layer. The first outer shell has a placement platform inside, with the right side of the placement platform contacting the left side of the protective layer. The left end of the first outer shell has an air inlet, and the right end of the first outer shell is threadedly connected to the second outer shell. A clamping ring is fixedly connected to the left side of the second outer shell, with the left side of the clamping ring contacting the right side of the antibacterial layer. The right end of the second outer shell has an air outlet.

[0006] The above solution addresses the shortcomings of traditional filter materials in terms of antibacterial performance. By setting up a filter layer composed of a protective layer, a support layer, and an antibacterial layer, the antibacterial performance of the filter is significantly improved. This effectively inhibits the growth of bacteria and viruses, reduces the risk of secondary pollution, and achieves high-efficiency filtration and multiple protection functions, making it suitable for various complex usage environments.

[0007] Furthermore, the protective layer is made of high-strength non-woven fabric.

[0008] Through the above solution, the high-strength non-woven fabric protective layer has excellent tensile strength and wear resistance, which can effectively protect the internal support layer and antibacterial layer from physical damage, enhance the overall structural strength of the filter, extend its service life, and maintain air permeability without affecting filtration efficiency.

[0009] Furthermore, the support layer is made of medium-efficiency filter cotton.

[0010] Through the above solution, the support layer made of medium-efficiency filter cotton can enhance the mechanical strength and support of the entire filter, ensuring sufficient filtration efficiency and a long service life.

[0011] Furthermore, the antibacterial layer is composed of a nanofiber membrane with polyacrylonitrile as the substrate.

[0012] Through the above method, the polyacrylonitrile nanofiber membrane has an extremely high specific surface area and porosity, which can effectively intercept tiny particles and bacteria. The nanoscale fiber structure enhances the filtration efficiency and retention capacity of the antibacterial layer.

[0013] Furthermore, the antibacterial layer is supplemented with silver ion antibacterial agents.

[0014] Through the above scheme, silver ions have broad-spectrum antibacterial activity and can destroy the cell wall or cell membrane of bacteria, thereby achieving a bactericidal effect. Adding silver ion antibacterial agents to nanofiber membranes can significantly improve their antibacterial performance.

[0015] Furthermore, activated carbon particles are added to the support layer.

[0016] Through the above method, activated carbon particles have a very strong adsorption capacity and can adsorb gas molecules, odors and certain harmful substances. Adding activated carbon particles to the support layer increases its adsorption capacity for harmful gases.

[0017] Furthermore, the outer surface of the protective layer is coated with an antistatic coating.

[0018] Through the above solution, the antistatic coating applied to the outer surface of the protective layer can effectively reduce dust accumulation caused by electrostatic adsorption and keep the protective layer clean.

[0019] Furthermore, the right side of the placement platform is fixedly connected with equidistant limiting rods, and the interior of the protective layer, support layer and antibacterial layer are all provided with equidistant limiting holes. The protective layer, support layer and antibacterial layer are slidably sleeved with the limiting rods through the limiting holes.

[0020] By using the above method, the protective layer, support layer and antibacterial layer are fitted onto the limiting rod through the limiting hole, which can improve the overall stability of the filter layer and effectively prevent the filter layer from shifting and deforming during the filtration process.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This antibacterial medium-efficiency filter cotton nanofiber composite filter significantly improves the filter's antibacterial performance by setting up a filter layer composed of a protective layer, a support layer, and an antibacterial layer. It effectively inhibits the growth of bacteria and viruses, reduces the risk of secondary pollution, and achieves high-efficiency filtration and multiple protection functions. It is suitable for various complex usage environments. The threaded connection between the first and second outer shells facilitates the disassembly, cleaning, or replacement of the filter layer, reducing the user's cleaning and maintenance burden and solving the problem of insufficient antibacterial performance of traditional filter materials.

[0033] Please see Figure 2 and Figure 3 The protective layer 101 is made of high-strength non-woven fabric. The high-strength non-woven fabric protective layer 101 has excellent tensile strength and wear resistance, which can effectively protect the internal support layer 102 and antibacterial layer 103 from physical damage, enhance the overall structural strength of the filter, extend its service life, and maintain air permeability without affecting the filtration efficiency.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The support layer 102 is made of medium-efficiency filter cotton. The medium-efficiency filter cotton support layer 102 can enhance the mechanical strength and support of the entire filter, ensuring sufficient filtration efficiency and a long service life.

[0035] Please see Figure 2 and Figure 3 The antibacterial layer 103 is composed of a nanofiber membrane with polyacrylonitrile as the substrate. The polyacrylonitrile nanofiber membrane has an extremely high specific surface area and porosity, which can effectively intercept tiny particles and bacteria. The nanofiber structure enhances the filtration efficiency and retention capacity of the antibacterial layer 103.

[0036] Please see Figure 2 and Figure 3 The antibacterial layer 103 contains silver ion antibacterial agent. Silver ions have broad-spectrum antibacterial activity and can destroy the cell wall or cell membrane of bacteria, thereby achieving a bactericidal effect. Adding silver ion antibacterial agent to the nanofiber membrane can significantly improve its antibacterial performance.

[0037] Please see Figure 2 and Figure 3 The support layer 102 is made of activated carbon particles. Activated carbon particles have a strong adsorption capacity and can adsorb gas molecules, odors and certain harmful substances. Adding activated carbon particles to the support layer 102 increases its adsorption capacity for harmful gases.

[0038] Please see Figure 2 and Figure 3The outer surface of the protective layer 101 is coated with an antistatic coating. The antistatic coating on the outer surface of the protective layer 101 can effectively reduce the accumulation of dust caused by electrostatic adsorption and keep the protective layer 101 clean.

[0039] Please see Figure 2 , Figure 3 and Figure 4 The right side of the placement platform 4 is fixedly connected with equidistantly arranged limiting rods 6. The protective layer 101, the support layer 102 and the antibacterial layer 103 are all provided with equidistantly arranged limiting holes 104. The protective layer 101, the support layer 102 and the antibacterial layer 103 are slidably sleeved with the limiting rods 6 through the limiting holes 104. The protective layer 101, the support layer 102 and the antibacterial layer 103 are sleeved on the limiting rods 6 through the limiting holes 104, which can improve the overall stability of the filter layer 1 and effectively prevent the filter layer 1 from shifting and deforming during the filtration process.

[0040] This embodiment of an antibacterial medium-efficiency filter cotton nanofiber composite filter significantly improves the antibacterial performance of the filter by setting a filter layer 1 composed of a protective layer 101, a support layer 102, and an antibacterial layer 103. It effectively inhibits the growth of bacteria and viruses, reduces the risk of secondary pollution, and achieves high-efficiency filtration and multiple protection functions. It is suitable for various complex usage environments. By setting a threaded connection between the first outer shell 2 and the second outer shell 3, it is easy to disassemble, clean, or replace the filter layer 1, reducing the user's cleaning and maintenance burden and solving the problem of insufficient antibacterial performance of traditional filter materials.

[0041] It should be noted that the limiting rod 6 and the clamping ring 7 are misaligned to avoid obstruction during the threaded connection of the first outer shell 2 and the second outer shell 3, which would prevent the first outer shell 2 and the second outer shell 3 from being unable to seal.

[0042] The working principle of the above embodiments is as follows:

[0043] When using this composite filter to filter air, air is first introduced into the filter through the air inlet 5 at the left end of the first housing 2. The air first comes into contact with the protective layer 101, which, made of high-strength non-woven fabric, provides initial filtration of large particles and effectively protects the internal support layer 102 and antibacterial layer 103 from physical damage, while maintaining breathability and allowing air to pass through smoothly. The antistatic coating on the outer surface of the protective layer 101 reduces dust accumulation caused by electrostatic adsorption, keeping the protective layer 101 clean. The air then passes through the support layer 102, which, made of medium-efficiency filter cotton, not only enhances the mechanical strength and support of the entire filter but also filters out larger particles and impurities in the air. The activated carbon particles added to the support layer 102 adsorb gas molecules, odors, and certain harmful substances, increasing the adsorption capacity for harmful gases. Finally, the air passes through the antibacterial layer 103. 3. The nanofiber membrane, made of polyacrylonitrile as the substrate, has an extremely high specific surface area and porosity, effectively intercepting tiny particles and bacteria. Simultaneously, the silver ion antibacterial agent added to the nanofiber membrane can destroy the cell walls or cell membranes of bacteria, thereby achieving a bactericidal effect and significantly improving its antibacterial performance. After passing through the above three layers of filtration, air is discharged from the air outlet 8 at the right end of the second outer shell 3. At this point, the air has been effectively purified and antibacterial. The three-layer filtration structure works synergistically to achieve both high-efficiency filtration and long-lasting antibacterial effects. When it is necessary to clean or replace the filter layer 1, the threaded connection between the second outer shell 3 and the first outer shell 2 can be unscrewed by rotating the second outer shell 3, allowing easy disassembly of the filter layer 1 for cleaning or replacement. This design simplifies the maintenance process and reduces the user's cleaning and maintenance burden. When the first outer shell 2 and the second outer shell 3 are rotated and spliced, the clamping ring 7 can press the filter layer 1 tightly onto the placement platform 4, ensuring the overall sealing effect of the filter and the stability of the filter layer 1.
