[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Combined with appendix Figures 1-3 :

[0022] A high-powered fan includes a cylindrical body 1, a grip part 2, a power component 3, an air duct component 4, and a control module 5. The cylindrical body 1 has a tapered air outlet 11 at its front end, a grip part 2 connected to its end, and a power component 3 axially arranged inside the cylindrical body 1.

[0023] The grip part 2 adopts an ergonomic curved surface design and has an anti-slip texture 21 on the surface. The bottom of the grip part 2 is provided with a cover 22, and the cover 22 is provided with a removable heat dissipation and dustproof mesh 23. The cover 22 is provided with a Type-C charging port 54 for powering the battery.

[0024] Through this structure, the ergonomic curved surface design matches the natural curvature of the palm, and the anti-slip texture 21 forms grooves to enhance grip friction. The detachable heat dissipation and dustproof mesh 23 is made of stainless steel woven mesh, which effectively blocks a large number of particles while ensuring air circulation. The detachable design makes it easy to clean in time and prevent blockage. The Type-C charging port enables fast charging, which is existing technology and therefore not described in detail here.

[0025] Combined with appendix Figures 1-3 :

[0026] The power assembly 3 includes an axial motor and a turbine fan blade assembly. The grip 2 has a control module 5 for controlling the power assembly 3 in the middle. The control module 5 is integrated on the grip 2 and includes a wind power adjustment button 51, a power switch 52 and an LED display unit 53.

[0027] With this structure, the wind speed adjustment key 51 can adjust the wind speed, the power switch 52 is used to control the switch, and the LED display unit 53 has built-in programmable LED beads that synchronously display the wind speed level through PWM dimming technology.

[0028] Combined with appendix Figures 2-4 :

[0029] A duct assembly 4 is provided between the power component 3 and the tapered air outlet 11 inside the cylindrical body 1. The duct assembly 4 includes a first flow guide assembly 41 and a second flow guide assembly 42. The first flow guide assembly 41 is located at the front end of the power component 3 and is fixedly connected to the power component 3. The second flow guide assembly 42 is rotatably connected to the first flow guide assembly 41. The first flow guide assembly 41 includes an inner circular hole frame 411 fixedly installed with the cylindrical body 1. An inner spiral air duct cylinder 413 is provided inside the inner circular hole frame 411. A plurality of evenly distributed first flow guide vanes 412 are provided between the inner spiral air duct cylinder 413 and the inner circular hole frame 411. A diffuser cavity is formed between two adjacent first flow guide vanes 412. The second flow guide assembly 42 includes a rotating sleeve 421 sleeved with the inner spiral air duct cylinder 413. The rotating sleeve 421 can rotate axially on the inner spiral air duct cylinder 413. A plurality of evenly distributed second flow guide vanes 422 are provided outside the rotating sleeve 421. An annular frame 423 is provided outside the plurality of evenly distributed second flow guide vanes 422.

[0030] Through this structure, the spiral angle design of the inner spiral duct 413 converts the tangential airflow generated by the turbine blades into axial flow. The second guide vane 422 rotates along with the airflow dispersed by the first guide vane 412 via the rotating sleeve 421. As it rotates, the second guide vane 422 and the first guide vane 412 continuously intersect, causing the pressure between the first guide vane 412 and the second guide vane 422 to continuously increase and decrease, thereby generating a relative negative pressure. This causes the airflow entering the tapered outlet 11 after passing through the inner spiral duct 413 to produce regular changes in intensity, further increasing the airflow volume that ultimately flows out of the tapered outlet 11.

[0031] Combined with appendix Figures 2-4 :

[0032] The cylindrical body 1 is provided with an air intake grille assembly 6 at the rear. The air intake grille assembly 6 includes an elliptical air intake grille 61. The elliptical air intake grille 61 is provided with a surrounding air intake channel 62. The inner wall of the surrounding air intake channel 62 is provided with a noise reduction hole array 63. The noise reduction hole array 63 is distributed in a gradient, and the hole diameter decreases by 0.2-0.5 mm along the airflow direction.

[0033] With this structure, the noise reduction aperture array 63 is distributed in a gradient, with the aperture decreasing along the airflow direction. This can absorb vibrations of different frequencies, maintaining air intake efficiency while reducing noise.

[0034] In practical implementation, the user can start the device via the power switch 52 on the grip 2, and the LED display unit 53 displays the current wind speed level in real time. When the axial motor drives the turbine fan blade assembly to rotate at high speed, the airflow is drawn in through the surrounding air intake channel 62 of the rear air intake grille assembly 6, and enters the power assembly 3 after high-frequency noise is eliminated by the gradient noise reduction array 63.

[0035] After being accelerated by the turbine blade assembly, the high-speed airflow first undergoes a tangential rotational flow state conversion through the inner spiral duct 413 of the first guide assembly 41. Then, it enters the first guide vane 412 and rotates as the airflow passes through the first guide vane 412. At the same time, the second guide vane 422 and the first guide vane 412 continuously intersect, causing the pressure between the first guide vane 412 and the second guide vane 422 to continuously increase and decrease, thereby generating a relative negative pressure. This causes the airflow that enters the tapered outlet 11 after passing through the inner spiral duct 413 to produce regular changes in strength, further increasing the airflow volume that finally flows out of the tapered outlet 11.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
