Technical Field

[0001] This utility model belongs to the field of air purifier technology, specifically relating to a return air vent air purifier. Background Technology

[0002] Indoor air pollutants mainly include bacteria, viruses, particulate matter, odors, and harmful gases. These pollutants not only affect air freshness but can also trigger respiratory illnesses, allergic reactions, and other health problems. Therefore, air purification equipment has become an important tool for improving indoor air quality and protecting health.

[0003] Existing air purification technologies generally rely on different purification methods for air filtration and purification. Common technologies include physical filtration, chemical adsorption, plasma purification, and ultraviolet sterilization. Physical filtration typically uses filters to remove large particulate matter from the air, such as dust and pollen, while chemical adsorption mainly relies on materials such as activated carbon to adsorb harmful gases and odors. Plasma purification technology uses high-energy ionization to decompose microorganisms and bacteria in the air. Ultraviolet sterilization technology can effectively kill pathogenic microorganisms in the air. Although these technologies each have their unique purification effects, a single purification method is often insufficient to meet the comprehensive needs of modern indoor air purification.

[0004] Currently, most air purifiers on the market use a single purification method, which still has certain limitations in terms of purification effect, equipment maintenance, and service life, resulting in a poor user experience.

[0005] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0017] like Figs. 1 to 3 As shown, an air purifier with a return air vent includes a mounting housing 10. An mounting slot 11 is provided inside the mounting housing 10. An activated carbon purification plate 20 is installed inside the mounting slot 11. A filter screen 30 is installed at the front of the activated carbon purification plate 20. An adsorption screen 40 is installed at the front of the filter screen 30. A plasma screen 50 is installed at the front of the adsorption screen 40. The plasma screen 50, the adsorption screen 40, the filter screen 30, and the activated carbon purification plate 20 are arranged sequentially. During use, polluted air enters the interior through the opening of the mounting housing 10. The air first passes through… The air passes through the plasma mesh plate 50, where high-energy discharge breaks down microorganisms and decomposes some particulate pollutants. The air then enters the adsorption mesh plate 40, where finer particles, suspended matter, and some odor molecules are captured. The air then passes through the filter mesh plate 30, where larger particles (such as dust and pollen) are effectively intercepted. Finally, the air passes through the activated carbon purification plate 20, where residual odors and harmful gases are efficiently adsorbed. The purified fresh air is then discharged from the return air vent, improving indoor air quality. Through multi-layer purification, it can comprehensively remove particulate matter, bacteria, viruses, and harmful gases. The purification components are easy to disassemble and replace, simple to maintain, and have a long service life.

[0018] In practical implementation, a mounting bracket 12 is installed on the front of the mounting housing 10. The mounting bracket 12 is connected and fixed to the mounting housing 10 by fasteners. A louvered fan plate 60 is installed inside the mounting bracket 12. The louvered fan plate 60 has symmetrical fan plate connecting parts 61 on both sides. The mounting bracket 12 has symmetrical connecting holes 121 on both inner sides. The fan plate connecting parts 61 and the connecting holes 121 correspond one-to-one and are connected and fixed by fasteners passing through the fan plate connecting parts 61 and the connecting holes 121, so that the louvered fan plate 60 is fixedly installed in the mounting bracket 12. When in use, external air enters through the opening of the louvered fan plate 60. The angle design of the louvered fan plate 60 can guide the air to flow evenly to the purification component and avoid the influence of direct current on the purification effect.

[0019] In practical implementation, the upper and lower sides of the mounting slot 11 are symmetrically provided with a first mounting slot 111, a second mounting slot 112, and a third mounting slot 113, respectively.

Thus, the plasma screen plate 50, the adsorption screen plate 40, the filter screen plate 30, and the activated carbon purification plate 20 are sequentially installed in the mounting housing 10. The structure is simple, easy to assemble, and can be quickly assembled or disassembled, making it convenient for cleaning and maintenance.

[0020] In practical implementation, a disinfection lamp assembly 70 is installed at the rear of the mounting slot 11. The disinfection lamp assembly 70 is connected and fixed to the mounting housing 10 by fasteners. During use, the air purified by the plasma mesh plate 50, the adsorption mesh plate 40, the filter mesh plate 30 and the activated carbon purification plate 20 flows to the area of ​​the disinfection lamp assembly 70. Microorganisms in the air are exposed to the ultraviolet light of the disinfection lamp, and their DNA or RNA structure is destroyed, making them unable to continue to reproduce or survive. The air disinfected by ultraviolet light is discharged from the equipment outlet, providing a more hygienic air quality for the indoor environment.

[0021] In practical implementation, a control component 80 is installed on one side of the mounting housing 10. The front part of the control component 80 is connected to an indicator panel 81 and a control switch 82. The surface of the indicator panel 81 is provided with several indicator lights 811. When in use, pressing the control switch 82 starts the air purifier, so that the control component 80 receives a signal to drive the air purifier to work. The indicator panel 81 drives the indicator lights 811 to be powered on and illuminate, indicating the working status.

[0022] In summary, the housing 10 has an internal mounting slot 11, inside which an activated carbon purification plate 20 is installed. A filter screen 30 is installed at the front of the activated carbon purification plate 20, an adsorption screen 40 is installed at the front of the filter screen 30, and a plasma screen 50 is installed at the front of the adsorption screen 40. The plasma screen 50, the adsorption screen 40, the filter screen 30, and the activated carbon purification plate 20 are arranged sequentially. This utility model's return air vent air purifier, through multi-layer purification, can comprehensively remove particulate matter, bacteria, viruses, and harmful gases. The purification components are easy to disassemble and replace, convenient for cleaning and maintenance, and have a long service life.
