[0026] See Figures 1-8 shown, which is a portable high-speed fan with air intake in the middle, and it includes a housing 1, an air supply component 2 installed in the housing 1, and a battery 3 for power supply.

[0027] An air inlet hole 101 is provided on the outer periphery of the middle part of the housing 1. The lower part of the housing 1 is a hand-held part 102 for a human hand to hold. A wind duct 40 communicating with the air inlet hole 101 is provided inside the upper part of the housing 1. And an air outlet 103 communicating with the wind duct 40 is provided at the top or the outside of the upper end of the housing 1. The air supply assembly 2 is arranged at the lower end of the wind duct 40 and is used to draw the outside air from the air inlet hole 101 to form wind, and the wind is discharged from the air outlet 103 after passing through the wind duct 40. That is to say, in the present utility model, the air inlet hole 101 is arranged on the outer periphery of the middle part of the housing 1 and above the hand-held part 102, which does not affect the air intake of the air inlet hole 101. That is, after the user's hand holds the hand-held part 102, the air inlet hole 101 will not be covered, ensuring that the air inlet hole 101 can intake air normally. At the same time, in the present utility model, the air outlet 103 is arranged at the top or the outside of the upper end of the housing 1, and the wind duct 40 is arranged between the air inlet hole 101 and the air outlet 103, so that the housing 1 of the present utility model can be set as a straight strip or a slightly curved strip, making the overall size of the present utility model relatively small, especially the width of the upper end is small, and the space it needs to occupy is relatively small, so it is extremely convenient to carry. Moreover, in the present utility model, the air inlet hole 101 is arranged on the outer periphery of the middle part of the housing 1, and the air outlet 103 is arranged at the top or the outside of the upper end of the housing 1, so that the length of the wind duct 40 between the air inlet hole 101 and the air outlet 103 is relatively short, which can effectively avoid the phenomenon of air leakage, and further ensure that the wind force is large, and the air volume is also relatively large, so that the wind effect is high, which can enhance the user experience and has an excellent function of cooling and reducing temperature, making the present utility model have extremely strong market competitiveness.

[0028] In this embodiment, the housing 1 is in a straight strip shape, thereby effectively reducing the width dimension of the present utility model and making the overall size relatively small, so as to be convenient for carrying and storing.

[0029] The air inlet holes 101 are plural and are distributed in a circle on the outer periphery of the middle part of the housing 1, which can ensure the air intake volume, and further improve the wind force, air volume and wind effect of the present utility model better.

[0030] A wind duct support 4 is provided on the upper part of the housing 1, the wind duct 40 is arranged on the wind duct support 4, and the air supply assembly 2 is arranged at the lower end of the wind duct support 4.

[0031] The air duct bracket 4 is an integrated structure; or, the air duct bracket 4 is a split two-piece structure, which includes a first air duct bracket 41 and a second air duct bracket 42 that are buckled and fixed together, the first air duct bracket 41 is provided with a buckle body 411, and the second air duct bracket 42 is provided with a buckle ring 421, the buckle body 411 and the buckle ring 421 are buckled and fixed, which is convenient for installation. Among them, the first air duct bracket 41 is also provided with a positioning flange 412, and the second air duct bracket 42 is provided with a positioning groove 422 adapted to the positioning flange 412, the positioning groove 422 and the positioning flange 412 are mutually nested and installed, and form a stable positioning to ensure the stability of the assembly structure of the air duct bracket 4. In this embodiment, the air duct bracket 4 is a split two-piece structure.

[0032] The air duct 40 is in an L-shape, an inverted L-shape, or a reversed L-shape, so that the air outlet 103 is disposed on the outer side of the upper end of the housing 1 .

[0033] The air duct 40 includes a straight section 401 connected to the air inlet 101, an arc section 402 connected to the straight section 401 and smaller than the straight section 401, and a horizontal section 403 connected to the arc section 402, the horizontal section 403 is connected to the air outlet 103, and the air outlet 103 is arranged on the outer side of the upper end of the shell 1; the air supply component 2 is arranged at the lower end of the straight section 401. When working, the air supply component 2 draws in external air from the air inlet 101 to form wind, and the wind enters the arc section 402 with a smaller size through the straight section 401. At this time, the wind will be compressed to a certain extent, which makes it easier to increase the wind pressure and then increase the wind force. Finally, the wind is discharged through the horizontal section 403 and the air outlet 103, so as to achieve the effect of blowing out strong wind. At the same time, it uses the arc section 402 to convert the wind from the vertical direction to the horizontal direction. The inner wall of the arc section 402 is arc-shaped, which will not block the wind, but will smoothly guide the wind, thereby ensuring that a large amount of air is blown out of the air outlet 103, ensuring that the amount of air blown out is large and the wind efficiency is high.

[0034] The air outlet 103 is provided with a grid 404. The grid 404 may be integrally formed at the outlet of the horizontal section 403 and be a part of the air duct support 4. Alternatively, the grid 404 is a separate component, which is fixed at the air outlet 103 and docked with the outlet of the horizontal section 403. In this embodiment, the grid 404 is integrally formed at the outlet of the horizontal section 403 and is a part of the air duct support 4, which has a simpler structure and does not require the grid 404 to be installed additionally.

[0035] The air supply assembly 2 includes a motor bracket 21 installed in the housing 1 and a high-speed motor 22 installed in the motor bracket 21. The upper end of the motor bracket 21 is also nested with the lower end of the air duct bracket 4 to further enhance the stability of the assembly structure.

[0036] The high-speed motor 22 has an air guiding channel 200 connecting the air duct 40 and the air inlet hole 101. An air inlet 210 connecting the air inlet hole 101 is provided at the lower end of the motor bracket 21. When the high-speed motor 22 operates, it can suck in the outside air through the air inlet hole 101 and enter the air duct 40 after passing through the air guiding channel 200.

[0037] Specifically, the high-speed motor 22 includes a cylindrical shell 221, a high-speed motor main body 223 fixed in the cylindrical shell 221 by a plurality of ribs 222, and a fan blade 224 mounted on the rotating shaft at the lower end of the high-speed motor main body 223. An air guiding channel 200 connecting the air inlet 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 in the motor bracket 21. The structure of the high-speed motor 22 is simple and it has a self-contained air guiding channel 200, which is extremely convenient for assembly and use. Among them, the cylindrical shell 221 is also inlaid and installed inside the lower end of the air duct bracket 4 to connect the air guiding channel 200 with the air duct 40. A soft rubber shock pad 23 is sleeved outside the cylindrical shell 221. The soft rubber shock pad 23 contacts the air duct bracket 4 and 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 while reducing vibration.

[0038] The high-speed motor 22 can be a ducted fan motor.

[0039] In summary, in the present utility model, the air inlet hole 101 is arranged on the outer periphery of the middle part of the housing 1 and above the handheld part 102, which does not affect the air intake of the air inlet hole 101. That is, after the user holds the handheld part 102 with the hand, the air inlet hole 101 will not be covered, ensuring that the air inlet hole 101 can intake air normally. At the same time, the air outlet 103 is arranged at the top or the outside of the upper end of the housing 1, and the air duct 40 is arranged between the air inlet hole 101 and the air outlet 103, so that the housing 1 of the present utility model can be set as a straight bar shape or a slightly curved bar shape, making the overall size of the present utility model relatively small, especially the width of the upper end is small, and the space it needs to occupy is relatively small, so it is extremely convenient to carry. Moreover, in the present utility model, the air inlet hole 101 is arranged on the outer periphery of the middle part of the housing 1, and the air outlet 103 is arranged at the top or the outside of the upper end of the housing 1, making the length of the air duct 40 between the air inlet hole 101 and the air outlet 103 relatively short, which can effectively avoid the phenomenon of air leakage, thereby ensuring a relatively large wind force and a relatively large air volume, so the wind effect is high, which can enhance the user experience and has an excellent function of cooling and reducing temperature, making the present utility model have extremely strong market competitiveness.
