[0044] The present application will be further described in detail by the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become more apparent.

[0045] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0046] According to this utility model, an air purifier with a dual-motor, dual-fan structure, featuring unidirectional air intake and opposite-directional air outlet, is provided. Figures 1-2 As shown, an air inlet 2 is provided in the middle section of the main body 1 of the purifier.

[0047] A first fan 3 is installed at the upper end of the air inlet 2, a first air outlet 4 is installed at the upper end of the first fan 3, and a first filter element 5 is installed between the first fan 3 and the first air outlet 4.

[0048] A second fan 6 is provided at the lower end of the air inlet 2, a second air outlet 7 is provided at the lower end of the second fan 6, and a second filter element 8 is provided between the second fan 6 and the second air outlet 7.

[0049] Traditional air purifiers typically use a single fan. To improve purification efficiency, the fan speed is often increased. However, this increased speed leads to higher requirements for motor quality control and increased noise. This invention improves air purifier efficiency by increasing the number of fans.

[0050] This invention uses a dual-fan design to replace the single high-speed fan in traditional air purifiers, thereby reducing production costs and noise. During the development of this invention, it was discovered that while a dual-fan design increases airflow, airflow interference between the two fans can easily occur, which also generates noise. Further optimization is needed to reduce this noise issue. In this invention, the air inlet is located in the middle of the purifier body, and an air duct is located at each of the top and bottom ends. This ensures that the airflow generated by the two fans does not interfere with each other. The airflow layout features bidirectional air intake in the middle and unidirectional air outlet at the top and bottom. This airflow arrangement results in lower noise compared to simultaneous airflow in one direction.

[0051] Furthermore, since the upper and lower air ducts are driven by different fans, the air pressure and wind speed within the air ducts can be minimized, thereby achieving more efficient air volume output.

[0052] Specifically, such as Figure 1 As shown, an air inlet 2 is provided in the middle section of the purifier body 1, a first fan 3 is provided above the air inlet 2, a first air outlet 4 is provided above the first fan 3, a second fan 6 is provided below the air inlet 2, and a second air outlet 7 is provided below the second fan 6.
