Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air handling equipment technology, specifically to a filter and an air conditioner. Background Technology

[0002] Currently, air conditioner filters are usually made of polypropylene (PP) mesh material, which easily causes bacteria and mold to accumulate, and is difficult to clean when it gets dusty. There is also the problem that vigorous scrubbing can easily damage the mesh. Utility Model Content

[0003] The technical problem to be solved by this application is to provide a filter and an air conditioner, which is less likely to cause bacteria and mold to accumulate and is easy to clean when dusty.

[0004] This application provides a filter screen, including: an antibacterial and anti-mildew filter screen; and a hydrophobic layer disposed on the surface of the antibacterial and anti-mildew filter screen.

[0005] The filter screen provided in this embodiment employs an antibacterial and anti-mold filter screen, achieving antibacterial and anti-mold effects. This prevents bacteria and mold from accumulating on the filter screen and reduces the binding effect of bacteria and mold on dust, thus reducing dust adhesion. Furthermore, the filter screen also features a hydrophobic layer, which reduces the binding effect of moisture on dust, further reducing dust adhesion. Thus, when cleaning the filter screen, the rinsing water can mix with the dust and be washed away, making it easy to clean.

[0006] Based on the above technical solution, the following improvements can be made to this application.

[0007] In one exemplary embodiment, the hydrophobic layer is a polymer coating.

[0008] In one exemplary embodiment, the polymer coating is a polytetrafluoroethylene coating.

[0009] In one exemplary embodiment, the antibacterial and antifungal filter is a polypropylene filter with added antibacterial masterbatch.

[0010] In one exemplary embodiment, the antibacterial masterbatch is a polypropylene masterbatch with added antibacterial agent.

[0011] In one exemplary embodiment, the antibacterial agent includes at least one of titanium dioxide and silver ions.

[0012] In one exemplary embodiment, the thickness of the hydrophobic layer is in the range of 20 μm to 50 μm; and / or, the surface water static contact angle of the hydrophobic layer is greater than 90°.

[0013] In one exemplary embodiment, the diameter of the filter mesh is in the range of 0.18 mm to 0.22 mm; and / or, the mesh density of the filter mesh is 30 mesh.

[0014] In one exemplary embodiment, the filter screen further includes a support frame on which the antibacterial and antifungal filter screen is supported; and / or, the antibacterial and antifungal filter screen is an injection-molded one-piece structure.

[0015] This application also provides an air conditioner, including the filter screen described in any of the above embodiments. Attached Figure Description

[0019] 1. Antibacterial and mildew-proof filter screen, 11. Antibacterial masterbatch, 2. Hydrophobic layer, 3. Support frame. Detailed Implementation

[0020] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0021] Research has found that a major reason why filters in related technologies are difficult to clean is that they also accumulate bacteria, mold, moisture, and other substances, making the dust adhere more firmly and difficult to remove.

[0022] This application provides a filter screen, including: an antibacterial and anti-mildew filter screen 1 and a hydrophobic layer 2, wherein the hydrophobic layer 2 is disposed on the surface of the antibacterial and anti-mildew filter screen 1, such as... Figure 1 As shown.

[0023] The filter screen provided in this embodiment employs an antibacterial and anti-mold filter screen 1, which achieves antibacterial and anti-mold effects, making it difficult for bacteria and mold to accumulate on the filter screen. It also reduces the reinforcing effect of bacteria and mold on dust, thus helping to reduce dust adhesion. In addition, the filter screen is also provided with a hydrophobic layer 2. This hydrophobic layer 2 reduces the reinforcing effect of moisture on dust, further reducing dust adhesion. Thus, when cleaning the filter screen, the rinsing water can mix with the dust and be washed away, achieving an easy-to-clean effect for dust accumulation.

[0024] In some exemplary embodiments, the hydrophobic layer 2 is a polymer coating, which is easy to form on the antibacterial and antifungal filter 1 by spraying, coating or other methods.

[0025] In some embodiments, the polymer coating is a polytetrafluoroethylene (PTFE) coating. Besides its excellent hydrophobic properties, PTFE also possesses advantages such as acid and alkali resistance, resistance to various organic solvents, and high-temperature resistance.

[0026] Of course, the hydrophobic layer 2 is not limited to polytetrafluoroethylene coatings. For example, it can also be a hydrophobic coating of fluorinated polyethylene, organosilicon materials (such as polydimethylsiloxane, organosilicon resin), polystyrene, polyester, polyurethane, acrylic resin, epoxy resin, etc.

[0027] In some exemplary embodiments, the antibacterial and antifungal filter 1 is a polypropylene filter with added antibacterial masterbatch 11, such as... Figure 1 As shown. In other words, the base material of the antibacterial and anti-mildew filter 1 is polypropylene, which is the same material as conventional filter screens. It is easy to prepare using existing processes and equipment, and only requires the addition of antibacterial masterbatch 11 to the base material. The resulting antibacterial and anti-mildew filter 1 has the advantages of polypropylene, such as being lightweight, corrosion-resistant, and easy to process, and also has the ability to inhibit or kill bacteria, mold, and other microorganisms.

[0028] In some embodiments, the antibacterial masterbatch 11 is a polypropylene masterbatch with added antibacterial agent. In other words, the base material of the antibacterial masterbatch 11 is also polypropylene, consistent with the base material of the antibacterial and antifungal filter 1, which facilitates uniform mixing and good bonding between the antibacterial masterbatch 11 and the base material of the antibacterial and antifungal filter 1. The antibacterial agent enables the antibacterial and antifungal filter 1 to possess antibacterial and antifungal functions.

[0029] In some embodiments, the antibacterial agent includes at least one of titanium dioxide and silver ions. Titanium dioxide can generate highly oxidizing reactive oxygen species through photocatalysis, thereby destroying the microbial cell structure and achieving antibacterial and antifungal functions. Silver ions achieve antibacterial and antifungal functions by disrupting bacterial cell membranes and interfering with enzyme activity, and their slow-release properties help ensure long-term antibacterial and antifungal effects.

[0030] Of course, antibacterial agents are not limited to titanium dioxide and silver ions mentioned above; they can also be antibacterial agents such as zinc oxide and graphene.

[0031] In some exemplary embodiments, the antibacterial and antifungal filter 1 is an injection-molded one-piece structure. During the production process, polypropylene raw material containing antibacterial masterbatch 11 is injection-molded to obtain the antibacterial and antifungal filter 1. Then, a hydrophobic layer 2 is added to the antibacterial and antifungal filter 1, for example, by spraying, coating, or impregnation.

[0032] In some exemplary embodiments, the thickness of the hydrophobic layer 2 can be in the range of, but not limited to, 20 μm to 50 μm, such as 20 μm, 30 μm, 40 μm, 50 μm, and any range between 20 μm and 50 μm. A hydrophobic layer 2 within this thickness range can balance the hydrophobic performance and cost of the filter.

[0033] In some exemplary embodiments, the static water contact angle of the surface of the hydrophobic layer 2 is greater than 90°, making it difficult for liquid to spread on the surface of the hydrophobic layer 2. Therefore, the surface of the hydrophobic layer 2 is difficult to wet and has a good hydrophobic effect.

[0034] In some exemplary embodiments, the diameter of the filter mesh can be in the range of, but not limited to, 0.18 mm to 0.22 mm, such as 0.18 mm, 0.19 mm, 0.20 mm, 0.21 mm, 0.22 mm, etc., which helps to balance the filtration effect and cleaning difficulty of the filter mesh, and minimizes the impact of the filter mesh on the air volume.

[0035] In some exemplary embodiments, the mesh density of the filter can be, but is not limited to, 30 mesh, which helps to balance the filtration efficiency and cleaning difficulty of the filter and minimizes the impact of the filter on the airflow.

[0036] In some exemplary embodiments, the filter screen also includes a support frame 3, such as Figure 2 As shown. The antibacterial and anti-mildew filter 1 is supported by the support frame 3. The support frame 3 can be a flexible plastic frame, which can undergo moderate flexible deformation, facilitating the installation and removal of the filter in the air conditioner.

[0037] Tests have shown that the filter provided in this application embodiment has an antibacterial rate of up to 99.9%, a mildew resistance level of less than or equal to level 1, and hydrophobic properties.

[0038] This application also provides an air conditioner that includes a filter as described in any of the above embodiments, and thus has all the above-mentioned beneficial effects, which will not be repeated here.
