Detailed Implementation

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] like Figures 1-5 As shown, an air purifier includes:

[0029] Mounting housing 100, which has a mounting cavity 101 inside;

[0030] The bidirectional impeller 200 is rotatably disposed in the mounting cavity 101. Along the rotation axis of the bidirectional impeller 200, two air inlet surfaces 201 are arranged opposite each other on the bidirectional impeller 200, and the side of the bidirectional impeller 200 is an air outlet surface 202. The air inlet surface 201 and the air outlet surface 202 are connected.

[0031] A driving component, which is disposed in the mounting cavity 101 and is driven to connect with the bidirectional wind turbine 200;

[0032] Along the rotation axis of the bidirectional impeller 200, an air inlet 102 is provided on the mounting housing 100, and an air outlet 103 is provided on the side of the mounting housing 100. The air inlet 102 and the air outlet 103 are connected.

[0033] In this embodiment, the bidirectional impeller 200 has two air inlet surfaces 201 symmetrically arranged along its rotation axis, which can simultaneously draw air from the two opposite ends of the mounting housing 100, achieving bidirectional air intake, significantly improving the air handling capacity per unit time, and enhancing air circulation efficiency; the side of the bidirectional impeller 200 is the air outlet surface 202, which corresponds to and communicates with the air outlet 103 provided on the side of the mounting housing 100, so that the airflow is directly discharged radially after being pressurized by the impeller, effectively reducing wind resistance and reducing energy consumption.

[0034] like Figure 1 As shown, in one specific embodiment, the air purifier can achieve double-sided air intake and double-sided air outlet. In other extended embodiments, the number of side air outlet surfaces 202 can be adjusted.

[0035] Further defining the air outlet surface 202, it is provided with a first air outlet and a second air outlet, and a baffle plate 207 is fixedly provided between the first air outlet and the second air outlet.

[0036] The first and second air outlets correspond to different air outlet areas. Combined with the baffle 207 set in the middle, the airflow can be divided into two relatively independent channels to avoid mutual interference between airflows in different directions, achieve more precise airflow guidance and distribution, and improve air delivery efficiency.

[0037] Specifically, the first air outlet includes a plurality of first air guide blades 203 arranged in a ring around the rotation axis of the bidirectional impeller 200; the second air outlet includes a plurality of first air guide blades 203 arranged in a ring around the rotation axis of the bidirectional air outlet, and the first air guide blades 203 and the second air guide blades 204 are arc-shaped blades along the radial direction of the bidirectional impeller 200.

[0038] The curved guide vane design effectively guides airflow along a preset path, reducing airflow turbulence and energy loss, improving airflow concentration and guiding accuracy, thereby achieving more efficient air purification circulation. It should be noted that along the radial direction of the bidirectional impeller 200, the first guide vane 203 and the second guide vane 204 have the same curved bending direction.

[0039] Further defining the direction along the axis of the bidirectional wind turbine 200, the projection of the first guide vane 203 is located in the gap between two adjacent second guide vanes 204.

[0040] The staggered design helps to create a more uniform airflow distribution pattern, avoiding uneven purification effects caused by concentrated or missing airflow in local areas, thereby improving the overall quality of indoor air circulation.

[0041] More preferably, along the axial direction of the bidirectional wind turbine 200, a reinforcing ring 205 is fixedly provided on the outer side of the first guide blade 203 and the second guide blade 204, and the reinforcing ring 205 exhibits a gradual change in diameter as it gets closer to the center of the bidirectional wind turbine 200.

[0042] The reinforced ring 205 effectively connects and supports multiple guide vanes, enhancing the rigidity and deformation resistance of the entire air outlet. Especially under high-speed rotation, it can significantly improve the overall stability and durability of the impeller structure and extend the service life of the equipment.

[0043] In a further preferred embodiment, along the radial direction of the bidirectional wind turbine 200, an integral mounting ring 206 is provided at the inner end of the reinforcing ring 205. The ring wall of the mounting ring 206 is parallel to the axial direction of the bidirectional wind turbine 200. An mounting groove 104 is provided inside the mounting shell 100, and the mounting ring 206 extends into the mounting groove 104.

[0044] The ring wall of the mounting ring 206 is parallel to the axial direction of the bidirectional wind turbine 200, allowing the mounting ring 206 to penetrate deep into the mounting groove 104, which facilitates quick and accurate positioning and fixing of components, reducing assembly difficulty and labor costs; and after the mounting ring 206 extends into the mounting groove 104, the outer ring wall of the reinforcing ring 205 abuts against the mounting shell 100 to achieve installation positioning.

[0045] Further defined, the mounting cavity 101 is provided with a fixing part 105 and a connecting part 106. The fixing part 105 is integrally formed with the mounting shell 100, and the connecting part 106 is detachably connected to the mounting shell 100. The fixing part 105 and the connecting part 106 are provided with air intake grilles, and both the fixing part 105 and the connecting part 106 are provided with mounting grooves 104.

[0046] The integrated design of the fixing part 105 and the mounting shell 100 ensures the strength of the core structure and the stability of long-term use; while the connecting part 106 is detachable, which meets functional requirements without affecting the integrity of the overall structure. The detachable connecting part 106 simplifies the installation and replacement process of internal components (such as impeller, filter screen, etc.), reduces assembly difficulty, improves maintenance convenience, and facilitates rapid assembly and subsequent maintenance of the equipment.

[0047] Air intake grilles are provided on both the fixed part 105 and the connecting part 106, so that air can enter the purification system evenly from multiple directions, avoiding local airflow congestion or dead corners, thereby improving air purification efficiency and operating efficiency.

[0048] It should be noted that the fixing part 105 and the connecting part 106 are respectively provided on both sides of the bidirectional wind turbine 200.

[0049] Further defining the direction of rotation of the bidirectional wind turbine 200, multiple mounting blocks 107 are arranged in a ring at intervals on the connecting part 106 to form an enclosing cavity for enclosing the driving component.

[0050] The arrangement of multiple mounting blocks 107 surrounding the drive component to form a cavity provides all-around mechanical support for the drive component, ensuring its stability during operation, reducing displacement or damage caused by vibration or other external forces, and extending the service life of the equipment. Furthermore, the heat generated by the drive component can be dissipated through airflow within the mounting cavity 101.

[0051] It should be noted that the drive unit is connected to the windshield 207 via a drive mechanism.

[0052] When it is necessary to inspect or replace the drive components, the location of the drive components can be easily accessed by simply disassembling the corresponding connection part 106, without the need for large-scale disassembly of the entire machine, which greatly improves the convenience of maintenance and reduces maintenance costs.

[0053] More preferably, the mounting shell 100 is provided with a guide groove 108, and the connecting part 106 is provided with a guide block 109, which can extend into the guide groove 108.

[0054] The design of the guide groove 108 and the guide block 109 enables the connecting part 106 to be accurately aligned and inserted along a predetermined path during installation, simplifying the assembly steps and reducing the need for manual adjustment. The tight fit between the guide block 109 and the guide groove 108 can also effectively prevent the connecting part 106 from shifting or loosening during use, ensuring that it maintains the correct position for a long time and enhancing the stability and durability of the overall structure.

[0055] When cleaning, filter replacement, or other internal component maintenance is required, the guide groove 108 and guide block 109 are designed to facilitate quick disassembly and reinstallation of the connection part 106.
