Technical Field

[0001] This utility model relates to the field of air filters, and in particular to an oxygen-enriched air filter. Background Technology

[0002] Currently, some improved filters attempt to enhance filtration efficiency by adding catalysts or adsorbent materials, but these methods suffer from high costs, complex maintenance, and poor long-term effectiveness. Furthermore, existing technologies that increase intake oxygen concentration through oxygen-enriching devices (such as pure oxygen injection and membrane separation technology) are often structurally complex and energy-intensive, making them difficult to implement in small and medium-sized equipment.

[0031] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Please refer to Figures 1 to 3 This utility model provides an oxygen-enriched air filter, including a bottom cover 3, a top cover 1, a first filter element 2, a second filter element 5, and an oxygen-enriched filter membrane 4.

[0033] The first filter element 2 has a ring structure and is installed between the bottom cover 3 and the top cover 1;

[0034] The second filter element 5 is fitted inside the first filter element 2, and an annular oxygen-enriching cavity is formed between the first filter element 2 and the second filter element 5.

[0035] The oxygen-enriched filter membrane 4 is installed inside the oxygen-enriched cavity;

[0036] During use, the first filter element 2 and the second filter element 5 can perform secondary filtration of the air. The air entering the oxygen-enriched chamber comes into contact with the oxygen-enriched filter membrane 4, which releases some oxidizing ions or free radicals. When the air passes through the filter membrane, these substances can react with some pollutants in the air, oxidizing and decomposing them, thus playing a certain filtering role. At the same time, it increases the oxygen content in the air entering the generator, which theoretically allows the fuel to come into more complete contact with oxygen, helping to improve combustion efficiency and make combustion more complete.

[0037] In this embodiment, the oxygen-enriched filter membrane 4 is arranged around the outer wall of the second filter element 5, and the two ends of the oxygen-enriched filter membrane 4 are respectively connected to the unwinding shaft 6 and the winding shaft 7.

[0038] The unwinding shaft 6 is wound with an oxygen-enriched filter membrane 4. Since the service life of the oxygen-enriched filter membrane 4 is shorter than that of the filter element, replacing the entire air filter directly would result in the filter element being replaced before reaching its service life, which would be wasteful. Through the cooperation of the unwinding shaft 6 and the winding shaft 7, the used oxygen-enriched filter membrane 4 can be wound up and the unused oxygen-enriched filter membrane 4 can be unwound, thus extending the service life of the entire air filter.

[0039] In this embodiment, the top ends of the unwinding shaft 6 and the winding shaft 7 both extend upward, pass through the top cover 1 and are fixedly connected with gears, the two gears are meshed with each other, and one of the gears has a cross groove 9.

[0040] Using tools such as screwdrivers, the gears can be driven to rotate, causing the unwinding shaft 6 and the rewinding shaft 7 to rotate synchronously. Since the filter membrane is thin, the resulting synchronous tension deviation will not affect the use of the equipment.

[0041] In this embodiment, the bottom cover 3 is provided with multiple traction rods 8 arranged in a circumferential array on the surface of the oxygen-enriched cavity. After the oxygen-enriched filter membrane 4 is pulled by the traction rods 8, it forms a ring structure in the oxygen-enriched cavity.

[0042] In this embodiment, the oxygen-enriched filter membrane 4 is made of non-woven fabric, and the surface of the non-woven fabric is coated with an oxygen-enriched ion coating.

[0043] In this embodiment, the bottom cover 3 has a perforation at its bottom.

[0044] The working principle of this utility model is as follows:

[0045] The first filter element 2 and the second filter element 5 can perform secondary filtration of air. The air entering the oxygen-enriched chamber comes into contact with the oxygen-enriched filter membrane 4. The oxygen-enriched filter membrane 4 releases some oxidizing ions or free radicals. When air passes through the filter membrane, these substances can react with some pollutants in the air and oxidize and decompose them, thereby playing a certain filtering role. At the same time, it increases the oxygen content in the air entering the generator, which theoretically allows the fuel to come into more complete contact with oxygen, helps to improve combustion efficiency, and makes combustion more complete.

[0046] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0047] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
