[0002] Air purifiers, as a common device, play a vital role in modern air purification technology. One of their core components is the impeller, which rotates to draw in and deliver air. However, most common impeller designs on the market today suffer from structural limitations. Traditional impellers typically feature only one set of blades, a single air inlet, and a single, circular air outlet.

[0003] Due to its single set of blades, the impeller's airflow is limited during operation, resulting in low air inflow and outflow velocities. Furthermore, the single inlet and outlet layout results in uneven air flow, potentially causing localized blockages in the air inlet area, further reducing air inflow and outflow efficiency. Due to the limitations of the impeller's design, the device may generate considerable noise during operation, impacting the user experience.

[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and the present invention is made based on this situation. Utility Model Content

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] like Figures 1 to 5 As shown, the present invention relates to a bidirectional air inlet impeller designed to improve both air intake and air discharge efficiency. The impeller's basic structure comprises a support plate 1, with a plurality of circumferentially arranged first blades 11 disposed on one side of the support plate 1 and a plurality of circumferentially arranged second blades 12 disposed on the other side of the support plate 1. These second blades 12 cooperate with the first blades 11 to form a symmetrical design, enhancing overall aerodynamic performance.

[0025] An annular first cover plate 2 is provided at the outer periphery of the first blade 11, and an annular second cover plate 3 is provided at the outer periphery of the second blade 12. The functions of the first cover plate 2 and the second cover plate 3 are not only to seal the outer side of the first blade 11 or the second blade 12 to reduce airflow loss, but also to enhance air intake efficiency by optimizing the flow direction of the airflow.

[0026] A first air inlet 21 is located at the center of the first cover plate 2, allowing air to enter the impeller. A first air outlet 22 is located between any two adjacent first blades 11, forming an efficient air exhaust channel. Similarly, a second air inlet 31 is located at the center of the second cover plate 3, also allowing air to enter. A second air outlet 32 ​​is located between any two adjacent second blades 12.

[0027] As can be seen from the above structure, the utility model has two sets of blades, each set of blades has an air inlet and a circle of air outlets. This design enables the impeller to have the ability to intake air in two directions and to discharge air in multiple directions, thereby effectively improving the efficiency of air intake and discharge, ensuring that the equipment has the characteristics of large air volume and high wind speed during operation.

[0028] Furthermore, the first blades 11 and the second blades 12 on the left and right sides of the support plate 1 are staggered at a certain angle in the circumferential direction. Figure 1 As shown, the distance L between the outer ends of the first blade 11 and the second blade 12 is staggered.

[0029] This staggered design serves a dual purpose. First, it significantly enhances the impeller's structural strength. The staggered blades provide a more even distribution of aerodynamic forces during rotation, reducing localized stress concentrations and effectively minimizing the risk of damage under high-load conditions. This structural reinforcement ensures greater impeller stability during extended operation, extending its service life.

[0030] Secondly, this design also helps reduce the noise generated by the impeller during operation. In traditional impeller designs, the arrangement of the blades often causes violent collisions between the airflow and the resulting large aerodynamic noise. However, by staggering the first blade 11 and the second blade 12 in the circumferential direction, not only is the impact of the airflow when passing through the blades reduced, thus reducing the generation of aerodynamic noise, but the airflow also flows more smoothly inside the impeller, thereby effectively reducing the overall operating noise.

[0031] Furthermore, both the first blade 11 and the second blade 12 are curved blades. This curved blade design not only effectively guides airflow but also allows the blades to better cut through the airflow during its flow, thereby improving the efficiency of air intake and exhaust. Furthermore, the curved blade structure effectively reduces eddy currents generated by the airflow on the blade surface, helping to reduce turbulent losses and thus improving the overall performance of the device.

[0032] Furthermore, both the first blade 11 and the second blade 12 are designed to be wide on the outside and narrow on the inside. This means that the width of the blades gradually increases from the air inlet to the air outlet. This design not only optimizes the flow characteristics of the airflow but also effectively improves the working efficiency of the blades, allowing air to flow more smoothly through the blades, thereby reducing airflow resistance and the generation of vortices.

[0033] Furthermore, the first blade 11 and the second blade 12 have the same rotation direction, both of which are clockwise or counterclockwise. This design ensures that the first blade 11 and the second blade 12 can work together and give full play to their respective roles. When the impeller rotates, the interaction of the airflow between the first blade 11 and the second blade 12 can make the airflow flow more coherent, thereby improving the stability and efficiency of the overall airflow. By maintaining the same rotation direction, the airflow interaction between the blades can be maximized, enhancing the compression and discharge effects of the airflow.

[0034] Furthermore, a center hole 13 is provided at the center of the support plate 1, and a bearing 4 is provided in the center hole 13. This can reduce friction and enhance the motion efficiency of the rotating parts.

[0035] Furthermore, the first blade 11, the second blade 12 and the support plate 1 are integrally formed. Such a design not only significantly improves the strength of the overall structure, but also effectively reduces the number of assembly steps.

[0036] Furthermore, the inner side surfaces of the first cover plate 2 and the second cover plate 3 are provided with a plurality of retaining grooves 3a for retaining the first blade 11 or the second blade 12. The provision of these retaining grooves creates a stable retaining structure between the first cover plate 2 and the first blade 11, and between the second cover plate 3 and the second blade 12. The retaining grooves not only physically restrict the movement of the blades, but also increase the stability of the overall structure through effective retaining action, thereby preventing relative displacement during high-speed operation.

[0037] More specifically, Figure 5 As shown, the limiting slot 3a preferably includes two ridges arranged side by side and a groove provided between the two ridges, and a plurality of triangular latches are provided in the groove. This design not only increases the gripping force of the slot but also improves the reliability of the clamping connection. The combination of the ridges and the grooves can effectively prevent the blades from accidentally falling off. At the same time, the design of the triangular latches can, to a certain extent, accommodate and buffer the displacement caused by vibration or impact, thereby further enhancing the stability of the overall structure. The rationality of this structural design enables the equipment to maintain excellent performance even under high vibration or complex load conditions.

[0038] Of course, welding or bonding may be performed between the first cover plate 2 and the first blade 11 , and between the second cover plate 3 and the second blade 12 , for further fixation.
