- the end plate 1-200 is connected to one end of the shroud 1-100, and is provided with an air inlet 1-201 and a convex surface 1-202.
- the convex surface 1-202 is arranged around the air inlet 1-201 and is located on the side of the end plate 1-200 away from the air duct 1-101.
- the convex surface 1-202 extends from the shroud 1-100 toward the air inlet 1-201.
- the convex surface 1-202 can guide the flow of the gas flowing toward the wind wheel 123-20, and can adjust the angle of attack of the gas when it flows toward the wind wheel 123-20, thereby changing the gas entering the volute 123-10. This helps the gas to flow to the wind wheel 123-20 more smoothly, weakens the impact of the gas on the wind inlet end of the wind wheel 123-20, and thus reduces the operating noise generated by the fan during use, thereby improving the user experience of the product.
- the blade centerline 23-101 of the blade structure 23-100 can be a conic curve.

It is not difficult to understand that the blade structure 23-100 generally has a certain size, and accordingly, the blade centerline 23-101 can be a curve segment, that is, in some embodiments, the blade centerline 23-101 of the blade structure 23-100 can be a conic section.
- the blade centerline of the fan blade is mostly an arc, and most of them are single arcs.
- the single arc blade centerline means that the blade centerline is composed of a continuous arc shape, but in actual applications, the single arc blade centerline has poor controllability, and it is difficult to achieve a significant improvement in the fan efficiency by adjusting the parameters of the blade centerline; some fan blades also have blade centerlines in the form of double arcs or multiple arcs.
- the double arc or multiple arc blade centerline means that the blade centerline is composed of two or more connected arcs, but the double arc or multiple arc blade centerline has discontinuous curvature at the intersection of the arcs, which is easy to cause gas velocity loss in actual applications, and thus the performance improvement of the fan is also very limited.
- the blade centerline 23-101 of the blade structure 23-100 is a conic curve, which can make the curvature of the blade structure 23-100 change in the extension direction.
- the blade centerline 23-101 of the blade structure 23-100 can maintain continuous curvature, and thus compared with the double-arc or multi-arc blade centerline 23-101, it can reduce the speed loss during use, which is beneficial to further increase the maximum static pressure and air volume of the fan.
- the blade structure 23-100 is beneficial to increasing the air volume of the fan under the condition of equal energy consumption; in the process of increasing the air volume of the fan, since the blade structure 23-100 whose blade centerline 23-101 is a conic curve, it can also ensure that the power consumption of the fan is at a relatively low level, thereby reflecting that the blade structure 23-100 can maintain its performance under higher air volume static pressure, reduce the possibility of the fan stalling phenomenon, and can improve the performance of the fan.
