[0025] The present utility model will be further described below in conjunction with specific embodiments and the drawings.

[0026] See Figures 1-7 As shown, a portable high-speed fan capable of improving the grip feeling includes a housing 1 and an air supply component 2 installed in the housing 1.

[0027] Among them, the housing 1 is in a straight cylindrical shape, and the cross-section of the housing 1 is an arc triangle, which has three equal-length arc sides, so that there are three arc convex surfaces 104 on the periphery of the housing 1, and an arc surface 105 is provided at the junction of two adjacent arc convex surfaces 104; an air outlet 103 vertically distributed is provided on one of the arc surfaces 105; an air inlet hole 101 is provided in the middle of the housing 1, and the lower part of the housing 1 is set as a hand-held part 102 for people to hold. The air supply component 2 is arranged on the upper part of the housing 1 and is used to draw in the outside air from the air inlet hole 101 to form wind, and the wind is discharged from the air outlet 103, thereby realizing the function of cooling and reducing temperature. That is to say, the present utility model sets the housing 1 in a straight cylindrical shape, making the overall size of the present utility model relatively small, especially the width becomes smaller, and the space it needs to occupy is relatively small, so it is extremely convenient to carry; at the same time, in the present utility model, the cross-section of the straight cylindrical housing 1 is an arc triangle, so that there are three arc convex surfaces 104 on the periphery of the housing 1, and an arc surface 105 is provided at the junction of two adjacent arc convex surfaces 104, which is convenient for the middle part of the palm to cooperate with the fingers to bend and hold, covering the entire hand-held part 102, so that the fingertips can all abut against the arc surface 105 provided with the air outlet 103 at the upper end in the hand-held part 102, so that the hand-held part 102 can be better held. Especially the design of the arc surface 105 and the arc convex surface 104 can form a comfortable contact with the inner side of the palm, thereby ensuring the comfort level of the palm holding the hand-held part 102, improving the grip feeling, and enhancing the user experience; furthermore, the present utility model sets the air inlet hole 101 in the middle 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 holds the hand-held 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.

[0028] In addition, the external design of the present utility model is unique, with strong interest and aesthetic feeling, which can improve the market competitiveness of the product; especially on the arc surface 105 of the air outlet 103, the design is extremely unique, and the air outlet 103 is a vertically distributed strip-shaped opening, further enhancing the interest and aesthetic feeling of the present utility model. At the same time, the width of the air outlet 103 is small and the height dimension is large. This shaped air outlet 103 is conducive to increasing the wind pressure, thereby ensuring a large wind force and high wind efficiency, enhancing the user experience, and having an excellent function of cooling and relieving the heat. Further, a control knob 106 is also provided on the arc surface 105. The control knob 106 is located directly below the air inlet hole 101 and on the hand-held part 102. The design of the air inlet hole 101 and the control knob 106 on the arc surface 105 can further enhance the interest and aesthetic feeling of the present utility model. At the same time, when holding the entire hand-held part 102 with the palm in the middle and the fingers bent, the ends of the fingers can all abut against the arc surface 105 of the hand-held part 102 with the air outlet 103 provided at the upper end. This can not only better hold the hand-held part 102, but also better control the control knob 106, making it extremely convenient to use.

[0029] The specific structure of the housing 1 is as follows: The housing 1 includes an upper housing 11, a metal mesh 12, and a lower housing 13 that are connected in sequence from top to bottom. Among them, the cross-sectional shapes of the upper housing 11, the metal mesh 12, and the lower housing 13 are the same, all being arc triangles; the metal mesh 12 has a plurality of the air inlet holes 101. That is to say, the metal mesh 12 not only plays a role in air intake, but also has a good decorative effect, thereby being able to enhance the decorative effect of the present utility model. In this embodiment, the upper housing 11 and the lower housing 13 are both tubular structures that are through from top to bottom, so a top cover 14 needs to be provided at the upper end of the upper housing 11 to cover the upper port of the upper housing 11, wherein the top cover 14 is inlaid in the upper port of the upper housing 11; similarly, a bottom cover 15 for covering the lower port of the lower housing 13 is provided at the lower end of the lower housing 13, and the bottom cover 15 is inlaid and installed in the lower port of the lower housing 13. A hanging rope hole 151 for passing through a hanging rope is further provided on the outer side of the bottom cover 15.

[0030] The lower housing 13 serves as the handle part 102.

[0031] In order to enable the air supply component 2 to draw in external air from the air inlet hole 101 to form wind, and for this wind to be discharged more smoothly from the air outlet 103, the following design is also made: A duct support 4 is further provided on the upper part of the housing 1. The duct support 4 has a duct 40 corresponding to the air supply component 2 and communicating with the air outlet 103. That is to say, the air supply component 2 draws in external air from the air inlet hole 101 to form wind, and this wind then enters the duct 40. Under the guidance of the duct 40, the wind can be discharged more smoothly from the air outlet 103, and the air volume is also relatively large, thereby ensuring the wind effect and improving the cooling effect.

[0032] The duct 40 includes a straight tube section 401 communicating with the air inlet hole 101, an arc section 402 connected to the straight tube section 401 and smaller in size than the straight tube section 401, and a horizontal section 403 connected to the arc section 402. The horizontal section 403 communicates with the air outlet 103; the air supply component 2 is arranged at the lower end of the straight tube section 401. During operation, the air supply component 2 draws in external air from the air inlet hole 101 to form wind, and this wind enters the arc section 402 with a smaller size through the straight tube section 401. At this time, the wind will be compressed to a certain extent, thereby facilitating an increase in air pressure and then an increase in wind force. Finally, it is discharged through the horizontal section 403 and the air outlet 103, thereby achieving the blowing of a 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 does not block the wind but smoothly guides the wind, thereby ensuring a large air volume is blown out from the air outlet 103, ensuring a large air volume of the blown wind and a high wind effect.

[0033] In this embodiment, a grid 3 is provided at the air outlet 103, and the grid 3 is also correspondingly assembled with the outlet of the duct 40. Among them, the assembly structure of the grid 3 is: The duct support 4 is provided with an installation groove 41 at the outlet of the duct 40. A plug-in limit groove 42 extending downward is provided at the bottom of the installation groove 41. The plug 31 formed at the lower end of the grid 3 is inserted into the plug-in limit groove 42, and the grid 3 is pressed into the installation groove 41 and locked by screws. Its assembly structure is simple, the assembly structure is stable, and disassembly and assembly are relatively convenient. Among them, the grid 3 is installed at the outlet of the horizontal section 403.

[0034] The air supply component 2 includes a motor support 21 installed in the housing 1 and a high-speed motor 22 installed in the motor support 21. The upper end of the motor support 21 is also nested and installed with the lower end of the duct support 4, thereby ensuring the stability of the assembly structure. The high-speed motor 22 has a wind guide channel 220 communicating the duct 40 with the air inlet hole 101. An air inlet 210 communicating with the air inlet hole 101 is provided at the lower end of the motor support 21. When the high-speed motor 22 operates, it can draw in external air through the air inlet hole 101 and enter the duct 40 after passing through the wind guide channel 220. The metal mesh 12 is clamped and fixed at the lower end of the motor support 21 and covers the air inlet 210.

[0035] The air supply component 2 employs a high-speed motor 22, which has a high rotation speed, a large air volume, and a fast wind speed. Among them, the high-speed motor 22 can be a ducted fan motor.

[0036] A soft rubber shock pad 23 is sleeved outside the high-speed motor 22, and the soft rubber shock pad 23 is in contact with 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.

[0037] A battery 51 and a circuit board 52 are arranged in the handheld part 102. The battery 51 and the control knob 106 are both electrically connected to the circuit board 52, and the control knob 106 is a stepless speed regulation roller. A charging interface 152 for charging the battery 51 is also arranged at the bottom of the bottom cover 15, and the charging interface 152 is electrically connected to the circuit board 52.

[0038] In summary, the present utility model sets the housing 1 in a straight tube shape, making the overall size of the present utility model relatively small, especially the width becomes smaller, and the space it needs to occupy is relatively small, so it is extremely convenient to carry; at the same time, the cross-section of the straight tube-shaped housing 1 in the present utility model is an arc triangle, so that the outer periphery of the housing 1 has three arc convex surfaces 104, and the connection between two adjacent arc convex surfaces 104 is through an arc surface 105, which is convenient for the middle part of the palm to cooperate with the bending of the fingers to hold, covering the entire handheld part 102, so that the fingertips can all abut against the arc surface 105 provided with an air outlet 103 at the upper end in the handheld part 102, so that the handheld part 102 can be better held. Especially the design of the arc surface 105 and the arc convex surface 104 can form a comfortable contact with the inner side of the palm, thereby ensuring the comfort of the palm holding the handheld part 102, improving the grip feeling, and enhancing the user experience; furthermore, the present utility model sets the air inlet hole 101 in the middle 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's hand holds the handheld part 102, the air inlet hole 101 will not be covered, ensuring that the air inlet hole 101 can intake air normally.
