The lower end of the arc-shaped cylindrical shell 1 is arranged at the upper end of the air inlet part 500, and the inner cavity of the arc-shaped cylindrical shell 1 is communicated with the air inlet hole 501; when the air supply component 2 works, the air outside is drawn into the air inlet hole 501 to form wind, and the wind is discharged from the air outlet 31 after passing through the inner cavity of the arc-shaped cylindrical shell 1, so as to realize the function of cooling and enjoying the cool. That is to say, the present utility model arranges the air inlet part 500 with the air inlet hole 501 between the upper end of the handle part 400 and the lower end of the air supply part 100. That is, after the user holds the hand-held part 400 with the hand, the air inlet hole 501 will not be covered, ensuring that the air inlet hole 501 can normally intake air. And this design is also convenient for arranging the air outlet 31 at the top of the air supply part 100, so that the air supply part 100 can adopt the curved arc-shaped cylindrical shell 1, making the overall shape of the present utility model bent. Compared with the T-shaped hand-held fan, its width is smaller, and the space required is relatively small, so it is extremely convenient to collect and carry. At the same time, the curved arc-shaped cylindrical shell 1 can make the overall shape of the present utility model unique and more interesting, so as to better attract the favor of users.

[0027] The specific shape of the arc-shaped cylindrical shell 1 is as follows: the arc-shaped cylindrical shell 1 includes a vertical section 11, an arc-shaped bending section 12 and an inclined section 13 which are integrally connected from bottom to top. The arc-shaped bending section 12 forms an angle between the vertical section 11 and the inclined section 13. Among them, the angle between the vertical section 11 and the inclined section 13 is greater than or equal to 90 degrees. In this embodiment, the angle between the vertical section 11 and the inclined section 13 is about 100 degrees. Among them, the air supply component 2 is arranged in the vertical section 11 or the inclined section 13. As a preferred embodiment of this embodiment, the adopted scheme is: the air supply component 2 is arranged in the inclined section 13, and among them, the length of the inclined section 13 is greater than the length of the vertical section 11.

[0028] The vertical section 11 is arranged at the upper end of the air inlet part 500, and the vertical section 11, the air inlet part 500 and the handle part 400 are combined to form a straight cylindrical structure, making the overall shape of the present utility model more beautiful, more interesting and smaller in size.

A wind guide channel 220 communicating with the air inlet hole is formed between the outer periphery of the high-speed motor main body 223 and the inner wall of the cylindrical shell 221. The cylindrical shell 221 is fixed inside the motor bracket 21. The structure of the high-speed motor 22 is simple, and it comes with a wind guide channel 220, which is extremely convenient for assembly and use. After the high-speed motor main body 223 drives the fan blade 224 to rotate at a high speed, the wind enters the arc-shaped cylinder shell 1 from the air inlet hole 501, passes through the wind guide channel 220, and finally blows out from the air outlet.

[0030] A soft rubber shock pad 23 is sleeved outside the cylindrical shell 221. The soft rubber shock pad 23 contacts the motor bracket 21. Through the design of the soft rubber shock pad 23, it can effectively reduce the vibration generated by the high-speed motor main body 223 during operation, thereby reducing noise and improving the user experience by reducing vibration.

[0031] The high-speed motor 22 can be a ducted fan motor.

[0032] A display screen 32 is arranged in the middle of the top cover 3.

In the present utility model, compared with the plastic holes, the air inlet holes 601 of the metal mesh ring 6 have relatively less air resistance and higher air inlet efficiency. Moreover, the metal mesh ring 6 can be disassembled and replaced. By replacing the metal mesh ring 6 with air inlet holes 601 of different sizes, different usage requirements can be met, and different decorative effects can also be achieved, thereby enhancing the market competitiveness of the present utility model.

[0036] The lower end of the arc-shaped cylinder shell 1 is fixedly connected to the upper end of the fixed bracket 5, and the upper end of the handle part 400 is fixedly connected to the lower end of the fixed bracket 5. Its assembly structure is simple, and the upper and lower ends of the metal mesh ring 6 are respectively in contact with the lower end of the arc-shaped cylinder shell 1 and the upper end of the handle part 400.

[0037] A circuit board 401 and a battery 402 for power supply are arranged inside the handle part 400. The circuit board 401 is connected to the battery 402, the display screen 32, and the high-speed motor 22.

[0038] In summary, the present utility model arranges the air inlet part 500 with air inlet holes 501 between the upper end of the handle part 400 and the lower end of the air supply part 100. That is, after the user holds the handheld part 400 with the hand, the air inlet holes 501 will not be covered, ensuring that the air inlet holes 501 can normally intake air. And this design is also convenient for arranging the air outlet 31 at the top of the air supply part 100, enabling the air supply part 100 to adopt a curved arc-shaped cylinder shell 1, making the overall shape of the present utility model curved. Compared with a T-shaped handheld fan, its width is smaller, and the space it occupies is relatively smaller, so it is extremely convenient to collect and carry. At the same time, the curved arc-shaped cylinder shell 1 can make the overall shape of the present utility model unique and more interesting, so as to better attract the favor of users.
