[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] See Figures 1-6 As shown, this utility model provides a high-efficiency, low-noise turbine blade 4 structure. The high-efficiency, low-noise turbine blade 4 structure provided by this utility model includes a base 2, which is a cylindrical structure that facilitates rotation. An umbrella part 3 is integrally formed on the upper part of the base 2, which is a conical structure that facilitates the arrangement and installation of the blade 4.

[0029] The rotating rod 1 is formed on the inner top surface of the umbrella part 3. The end of the rotating rod 1 is provided with a plug-in end 8. The bottom of the plug-in end extends out of the bottom surface of the base 2. The plug-in end 8 can be inserted into the corresponding mounting hole for fixing, so as to cooperate with the rotation support.

[0030] Fan blades 4 are arranged at equal intervals on the outer surface of umbrella part 3. The top edge of fan blades 4 is higher than the top surface of umbrella part 3, and the edge of fan blades 4 is chamfered to avoid collision and damage during high-speed rotation of fan blades 4, thus improving safety.

[0031] The positioning groove 5 is formed on the inner top surface of the base 2. A magnet 7 is inserted into the positioning groove 5. In order to facilitate the rotation of the fan blade 4, the magnetic drive is used for conveying, which can reduce the contact between the base 2 and other parts, reduce wear, and improve the stability of the fan blade 4 during rotation.

[0032] Preferably, the diameter of the bottom edge of the umbrella part 3 is larger than the diameter of the base 2, which allows the fan blade 4 to cover a larger area than the base 2, thereby increasing the airflow circulation speed.

[0033] Preferably, there are six fan blades 4 in total, with the upper and lower ends of the fan blades 4 overlapping each other. This structural design allows the fan blades 4 to generate greater wind pressure and air volume when rotating at high speed, enabling the fan to deliver more cool air in a shorter time. The airflow generated by the fan during rotation can be distributed more evenly, reducing airflow turbulence and eddies, thereby improving heat dissipation efficiency. The fan blades 4 are set with an inclination angle α, which is set in the range of 15-20°. After testing, the inclination angle α is preferably 16°. At the same time, combined with the leading edge shape set at the top of the fan blades 4, the smooth curvature change in the middle and the optimized trailing edge design can reduce airflow separation, improve airflow efficiency, reduce turbulence noise, and improve the stability of the equipment during operation.

[0034] Preferably, the thickness of the fan blade 4 is 0.5-1mm. Using this size setting can improve the fatigue strength and thermal stability of the fan blade 4, while reducing weight and improving overall performance.

[0035] Preferably, a support frame 6 is formed on the inner top surface of the umbrella part 3. The design of the support frame 6 can enhance the overall strength of the umbrella part 3, reduce the shaking during the operation of the fan, and ensure the stability of the fan during operation.

[0036] Preferably, the end face of the plug-in terminal 8 is chamfered, and the outer wall of the rotating rod 1 is formed with a positioning groove 5. The design of the positioning groove 5 can reduce the difficulty of the fan installation process and improve the disassembly and assembly efficiency.

[0037] With the above structure, when installing the fan blade 4, the bottom plug-in end 8 is inserted into the corresponding drive device for positioning. After insertion, the drive device drives the fan blade 4 to rotate, which causes the airflow to flow along the gap between the fan blades 4. The compression function of the fan blade 4 drives the airflow to move faster, thereby achieving the airflow delivery requirement. Due to the reasonable structural design of the fan blade 4, the fan blade 4 has good stability during rotation, which can significantly reduce the noise generated during operation, while ensuring airflow efficiency and meeting the usage requirements.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
