[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] It should be noted that the terms "first," "second," etc., used in this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with this disclosure.

[0020] Please see Figures 1-4 In this embodiment of the utility model, a fan housing includes a fan frame; a fan blade center ring 1 is provided inside the fan frame and is rotatably connected thereto; and a plurality of fan blade pieces 2 are provided at equal intervals around the outer wall of the fan blade center ring 1; the front surface of the fan blade pieces 2 is formed with first wind-gathering grooves 3 at intervals along the width of the fan blade pieces 2; the front surface of the fan blade pieces 2 is also formed with a plurality of second wind-gathering grooves 4; and the second wind-gathering grooves 4 are disposed between adjacent first wind-gathering grooves 3.

[0021] Specifically, by providing a first air-gathering groove 3 distributed along the width direction on the front surface of the fan blade 2 and a second air-gathering groove 4 located between adjacent first air-gathering grooves 3, the airflow is guided and concentrated in layers during the rotation of the fan blade 2, thereby improving the concentration of air supply and the efficiency of wind pressure output. The first air-gathering groove 3 is responsible for the main airflow guidance, while the second air-gathering groove 4 plays a role in supplementing air gathering and reducing turbulence. The overall structural design enables the fan to produce a stronger and more stable airflow effect at the same speed.

[0022] Furthermore, the rear surface of the fan blade 2 is formed with a number of protrusions 5 at intervals; and the positions of the protrusions 5 are set corresponding to the second air concentrator 4.

[0023] Specifically, by providing a protrusion 5 corresponding to the second air-gathering groove 4 on the rear surface of the fan blade 2, a rearward turbulence and airflow compensation effect can be formed when the fan rotates, making the airflow distribution on the front and rear surfaces more balanced. This not only enhances the guidance and air-gathering efficiency of the airflow passing through the fan blade 2, but also effectively reduces eddies and airflow losses, thereby improving the overall air supply stability and wind energy utilization rate.

[0024] Furthermore, the fan blade 2 is crescent-shaped.

[0025] Specifically, the fan blade 2 adopts a crescent-shaped structure design, which allows it to form a smoother airflow channel when rotating, reducing air resistance and noise generation. This shape can increase air pressure output while maintaining a large air volume and improve airflow guidance, thereby achieving higher aerodynamic efficiency and quieter performance.

[0026] Furthermore, an outer ring 6 of the fan blade is provided concentrically around the central ring 1 of the fan blade; and the outer surface of the fan blade component 2 is fixedly connected to the inner surface of the outer ring 6 of the fan blade.

[0027] Specifically, by concentrically setting an outer ring 6 around the central ring 1 of the fan blades and fixing the outer surface of each fan blade component 2 to the inner surface of the outer ring, the overall structural strength and stability of the fan blade component 2 can be effectively improved. This prevents deformation or vibration of the fan blade component 2 when the fan rotates at high speed, ensuring the uniformity and stability of airflow output, while also helping to reduce operating noise and extend the fan's service life.

[0028] Furthermore, the fan frame includes a main frame 7; and the rear side of the main frame 7 is provided with a mounting seat 8 for mounting the fan blade center ring 1; and a number of connecting pieces 9 are provided at equal intervals around the mounting seat 8 and the main frame 7.

[0029] Specifically, the fan frame adopts an integrated structure design of the main frame 7 and the mounting base 8. By setting several connectors 9 at equal intervals around the two, not only is the concentricity and stability of the fan blade center ring 1 installed, but the stress and vibration generated by rotation can also be evenly distributed during fan operation. This structure improves the overall mechanical strength and operational balance of the fan, thereby achieving a smoother rotation and a lower noise level.

[0030] Furthermore, screw mounting holes 10 are formed at all four corners of the main frame 7; and reinforcing plates 11 are provided at all four corners of the main frame 7.

[0031] Specifically, the main frame 7 features screw mounting holes 10 at its four corners, along with reinforcing plates 11, providing more stable support during fan installation. The addition of reinforcing plates 11 effectively improves the deformation resistance of the four corners of the frame, preventing structural loosening or cracking due to long-term vibration or uneven stress, thereby enhancing the installation reliability and service life of the entire fan assembly.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
