[0037] With the improvement of my country's economic development level, air pollution has become an important factor threatening people's health in public buildings, homes and other places. Therefore, it is crucial to effectively eliminate suspended particulate matter and microorganisms such as viruses, bacteria or fungi in the air and purify the air. Researching technologies and equipment with excellent air purification and disinfection functions is of great significance.

[0038] 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.

[0039] In ion purification equipment, air purification is mainly achieved by stacking and arranging multiple membrane electrodes 1 to form an adsorption module. However, the membrane assembly of existing ion purification equipment is mainly fixed by adhesive strips. Several hot-melt adhesive strips are applied to the side of the membrane electrode assembly to provide a fixing effect. However, these adhesive strips are prone to delamination over time, affecting the stability of the membrane electrode assembly.

[0040] To address the technical problem of membrane assembly in existing ion purification equipment being prone to delamination due to adhesive strip fixation, which affects the stability of the membrane electrode assembly, this application provides a membrane assembly structure based on adhesive fixation. By setting fixing holes 4 on the fixing frame 2, fixing adhesive strips 3 are placed in the fixing holes 4. Through the adhesion between the fixing adhesive strip 3 and the fixing holes 4, and the locking of the fixing holes 4 with the cured fixing adhesive strip 3, the technical effect of increasing the stability of the connection between the fixing adhesive strip 3 and the membrane electrode 1 is achieved.

[0041] like Figure 1 As shown, Figure 1This application provides a schematic diagram of a device diaphragm assembly structure based on colloid fixation, including a membrane electrode 1, a fixing frame 2, and a fixing adhesive strip 3. The diaphragm assembly structure is formed by stacking multiple layers of membrane electrodes 1 sequentially. The fixing frame 2 is located at the edge of the membrane electrode 1, and the membrane electrode 1 is unfolded and fixed within the fixing frame 2 through the fixing frame 2, so that the membrane electrode 1 is always in an unfolded state during use. The fixing frame 2 is provided with fixing holes 4 for locking the fixing adhesive strip 3. The fixing adhesive strip 3 is arranged along the stacking direction of the membrane electrode 1 and is fixedly connected to the fixing frame 2 through the fixing holes 4. The fixing adhesive strip 3 is placed in the fixing holes 4. Through the adhesion between the fixing adhesive strip 3 and the fixing holes 4, and the locking of the fixed adhesive strip 3 after curing, the technical effect of increasing the stability of the connection between the fixing adhesive strip 3 and the membrane electrode 1 is achieved.

[0042] For example, in this embodiment, the fixing strip 3 is made of hot melt adhesive material. Specifically, when the multilayer film electrode 1 is stacked in sequence, the fixing holes 4 on the fixing frame 2 of each layer of film electrode 1 overlap in projection along the stacking direction of the multilayer film electrode 1. Therefore, when fixing the multilayer film electrode 1 with hot melt adhesive material, the hot melt adhesive material is dripped from the side wall or bottom of the fixing frame 2 into the fixing holes 4 by a dispensing machine. The hot melt adhesive material seeps into the fixing holes 4 under the action of gravity. At this time, the hot melt adhesive material fills the fixing holes 4 and is tightly bonded to the fixing frame 2. At the same time, after the hot melt adhesive material cools and solidifies, it forms the fixing strip 3. The fixing holes 4 can also lock the solidified fixing strip 3, thereby achieving the technical effect of increasing the stability of the connection between the fixing strip 3 and the film electrode 1.

[0043] In some alternative embodiments, such as Figure 2 As shown, the fixing hole 4 is set at the edge of the fixing frame 2, and a groove-shaped structure is formed at the edge of the fixing frame 2. The opening of the groove-shaped structure is constricted. Therefore, when the fixing strip 3 is snapped into the fixing hole 4, the constricted opening of the fixing hole 4 can snap the fixing strip 3 into place, thereby improving the stability of the connection between the fixing strip 3 and the membrane electrode 1.

[0044] In other alternative embodiments, such as Figure 3 As shown, the fixing hole 4 is set at the edge of the fixing frame 2, and a groove structure is formed at the edge of the fixing frame 2. The side wall of the groove structure is provided with a snap-fit ​​part 5 that is set inward. When the hot melt adhesive material fills the fixing hole 4 and after the hot melt adhesive material cools and solidifies, the snap-fit ​​part 5 on the side wall of the groove structure will form a snap-fit ​​groove on the side wall of the fixing adhesive strip 3 that snaps into the snap-fit ​​part 5. At this time, the connection stability between the fixing adhesive strip 3 and the fixing frame 2 can be further increased by the snap-fit ​​groove on the side wall of the fixing adhesive strip 3 and the snap-fit ​​part 5 on the side wall of the groove structure.

[0045] In other alternative embodiments, such as Figure 4 As shown, the fixing hole 4 is located at the edge of the fixing frame 2, and a groove-like structure is formed at the edge of the fixing frame 2. The side wall of the groove-like structure is also provided with a fixing groove 6. When the fixing strip 3 is placed in the groove-like structure, the fixing strip 3 extends into the fixing groove 6. It can be understood that when the hot melt adhesive material fills the fixing hole 4, the hot melt adhesive material extends into the fixing groove 6, and after the hot melt adhesive material cools and solidifies, a snap-fit ​​part 5 is formed on the side wall of the fixing strip 3. At this time, the snap-fit ​​part 5 on the side wall of the fixing strip 3 snaps into the fixing groove 6 on the side wall of the groove-like structure, thereby increasing the stability of the connection between the fixing strip 3 and the fixing frame 2.

[0046] In other alternative embodiments, such as Figure 5 As shown, the fixing hole 4 includes a receiving groove 7 and a fixing hole 8. The fixing hole 8 is set on the frame, the receiving groove 7 is set on the edge of the frame, the fixing strip 3 is placed in the receiving part, and the fixing strip 3 is also provided with a buckle. The buckle extends towards the fixing hole 8 and is fixedly engaged with the frame through the fixing hole 8. The buckle extending towards the fixing hole 8 and engaging with the fixing hole 8 further increases the stability of the connection between the fixing strip 3 and the fixing frame 2.

[0047] In other alternative embodiments, such as Figure 6 As shown, the fixing hole 4 is located on the non-edge part of the fixing frame 2. The fixing strip 3 passes through the fixing hole 4 through the frame. It can be understood that in this embodiment, the fixing hole 4 has a closed structure. The side wall of the fixing hole 4 can restrict the fixing strip 3 within the fixing frame 2, thereby preventing the fixing strip 3 from detaching from the fixing frame 2.

[0048] In some embodiments, the fixing frame 2 is made of polyester resin material (PET), which has the advantages of being lightweight, corrosion resistant and having good electrical insulation.

[0049] In some embodiments, the sidewall of the fixed frame 2 is provided with at least one set of fixing strips 3. It is understood that, in this embodiment, the sidewall of the fixed frame 2 may be provided with one set of fixing strips 3 or multiple sets of fixing strips 3. The stability of the connection between each layer of membrane electrode 1 in the membrane assembly structure is enhanced as the number of sets of fixing strips 3 increases.

[0050] For example, in this embodiment, when multiple sets of fixing strips 3 are provided on the side wall of the fixed frame 2, the multiple sets of fixing strips 3 are evenly arranged on the opposite side walls of the frame, thereby making the fixing force evenly transmitted to the contact surface of the frame, avoiding local stress concentration, reducing the risk of frame deformation or cracking. Secondly, the fixing strips 3 symmetrically distributed on both sides of the fixed frame 2 form multi-point constraints, effectively suppressing the fixing strips 3 from falling off the fixed frame 2 due to vibration, temperature changes or external force.

[0051] 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.
