[0002] Effectively eliminating suspended particulate matter and microorganisms such as viruses, bacteria, and fungi in the air is crucial for air purification. Therefore, researching technologies and equipment that combine ultra-efficient air purification and disinfection is of great significance. In the home sphere, ion air purifiers are commonly used. These devices primarily achieve air purification by arranging multiple stacked membrane electrodes to form an adsorption module. However, the primary technical challenge in manufacturing these adsorption modules is how to more easily control the spacing between the membrane electrodes. Utility Model Content

[0003] To address the primary technical challenge of controlling the spacing between membrane electrodes more efficiently during the production of adsorption modules in ion purification equipment, this application provides a membrane assembly structure based on convex strip fixing. By setting convex strips on the membrane electrodes, when multiple layers of membrane electrodes are stacked sequentially, the convex strips on the lower layer of membrane electrodes support the upper layer of membrane electrodes, thereby spacing adjacent membrane electrodes apart. The thickness of the convex strips adjusts the spacing between the assembled membrane electrodes, thus achieving a more efficient control over the spacing between membrane electrodes.

[0032] Ion purification equipment, also known as air cleaners, air fresheners, or purifiers, refers to products that can adsorb, decompose, or transform various air pollutants, such as PM2.5, dust, pollen, odors, formaldehyde and other decoration pollution, bacteria, allergens, etc., increasing air circulation and effectively improving air cleanliness. Widely used in daily life, these products employ technologies such as adsorption, plasma, catalysis, photocatalysis, superstructure photomineralization, HEPA high-efficiency filtration, and electrostatic dust collection. Plasma air purifiers, particularly those using plasma technology, work by generating a large number of energetic electrons under an applied electric field, which bombard pollutant molecules, causing ionization, dissociation, and excitation. This triggers a series of complex physical and chemical reactions, transforming complex macromolecular pollutants into simple, safe small molecules, or converting toxic and harmful substances into non-toxic or low-toxic substances, thus degrading and removing pollutants. They offer advantages such as wide applicability, fast purification speed, and more comprehensive purification effects.

[0033] In ion purification equipment, air purification is mainly achieved by stacking and arranging multiple membrane electrodes 1 to form an adsorption module. In the process of producing the adsorption module, how to more easily control the spacing between the membrane electrodes 1 is the primary technical problem to be solved.

[0034] To address the primary technical challenge of controlling the spacing between membrane electrodes 1 more efficiently during the production of adsorption modules in ion purification equipment, this application provides a membrane assembly structure based on protrusions 2 for fixation. By setting protrusions 2 on the membrane electrodes 1, when multiple layers of membrane electrodes 1 are stacked sequentially, the protrusions 2 on the lower layer membrane electrodes 1 support the upper layer membrane electrodes 1, thereby spacing adjacent membrane electrodes 1 apart. The thickness of the protrusions 2 adjusts the spacing between the assembled membrane electrodes 1, thus achieving a more efficient control over the spacing between the membrane electrodes 1.

[0035] like Figure 1 As shown, Figure 1 This application provides a schematic diagram of a diaphragm assembly structure based on a convex strip fixing method, including a membrane electrode 1 and a convex strip 2. The convex strip 2 is disposed on the membrane electrode 1. When multiple membrane electrode 1s are stacked sequentially, the convex strip 2 on the lower membrane electrode 1 supports the upper membrane electrode 1, thereby spacing adjacent membrane electrode 1s apart. The thickness of the convex strip 2 is used to adjust the membrane spacing of the assembled membrane electrode 1s, which not only improves the assembly effect and efficiency of the multilayer membrane electrode 1s, but also allows for more precise control of the spacing between two adjacent membrane electrode 1s.

[0036] In some embodiments, a fixed frame 3 is included. The fixed frame 3 is disposed at the edge of the membrane electrode 1. The membrane electrode 1 is unfolded by the fixed frame 3 and fixed within the fixed frame 3, so that the membrane electrode 1 remains in an unfolded state during use, thereby improving the stability of the membrane electrode 1 during use. Secondly, in this embodiment, a protrusion 2 is disposed on the fixed frame 3. The fixed frame 3 provides a support point for the protrusion 2, thereby improving the stability of the protrusion 2 on the lower membrane electrode 1 in supporting the upper membrane electrode 1 during use.

[0037] In some alternative embodiments, such as Figure 2 As shown, one end of the protrusion 2 is fixedly mounted on the fixed frame 3, and the other end of the protrusion 2 extends to the other side of the fixed frame 3. During use, the end of the protrusion 2 extending to the other side of the fixed frame 3 can support the membrane electrode 1, thereby improving the stability of the membrane electrode 1 during use.

[0038] In some alternative embodiments, such as Figure 3 As shown, one end of the protrusion 2 is fixedly mounted on the fixed frame 3, and the other end of the protrusion 2 extends to the other side of the fixed frame 3. It can be understood that in this embodiment, the protrusion 2 spans across the membrane electrode 1, thereby enabling the protrusion 2 to support the membrane electrode 1 and provide mechanical support for the membrane electrode 1. During use, it can prevent the membrane electrode 1 from bending, thereby improving the stability of the membrane electrode 1 during use.

[0039] In some embodiments, the protrusion 2 is made of an insulating material, thereby forming an insulating gap between the membrane electrode 1, which can prevent short-circuit failure caused by contact between adjacent membrane electrode 1.

[0040] In some embodiments, ventilation channels are formed between the film electrodes 1, and the protrusions 2 are arranged along the airflow direction in the ventilation channels to reduce the wind resistance of the protrusions 2 and thereby improve the stability of the protrusions 2 during use.

[0041] In some embodiments, the fixing frame 3 is made of polyester resin material (PET), which has the advantages of being lightweight, corrosion resistant and having good electrical insulation.

[0042] In some embodiments, in this embodiment, the membrane electrode 1 is provided with a plurality of protrusions 2. By providing a plurality of protrusions 2 on the membrane electrode 1, local stress concentration can be avoided, the risk of tearing or deformation caused by excessive force at a single point can be reduced, and the stability of the membrane electrode 1 during use can be further improved.

[0043] In some embodiments, multiple protrusions 2 are evenly distributed on the membrane electrode 1, making the stress distribution on the membrane electrode 1 more uniform and further improving the stability of the membrane electrode 1 during use.

[0044] In some embodiments, the projections of the protrusions 2 on the multilayer film electrode 1 overlap along the stacking direction of the film electrode 1, so that when the multilayer film electrode 1 is stacked, the protrusions 2 on different film electrode 1 contact each other end to end in sequence, and the force is transmitted through the protrusions 2 on different film electrode 1, thereby improving the stability of the film electrode 1 during use.

[0045] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
