[0016] Explanation of the reference numerals: upper shell 1, bottom shell 2, air guide plate 3, wind wheel 4, motor 6, cooling fin 8, control main board 9, sleeve bracket 10, shock-absorbing sleeve 11, lighting indicator 12, rechargeable battery 13, function cover 14, bottom cover 15. DETAILED DESCRIPTION

[0017] See also Figure 1-Figure 2 As shown, the technical solution adopted in this specific implementation mode is: it includes an upper shell 1, a bottom shell 2, an air guide plate 3, a wind wheel 4, a motor 6, and a refrigeration fin 8. The upper shell 1 is connected to the bottom shell 2 by screws, the air guide plate 3 is arranged in the bottom shell 2, the wind wheel 4 is arranged on the air guide plate 3, the motor 6 is arranged on one side of the air guide plate 3 and is connected to the wind wheel 4 shaft. There are two refrigeration fins 8 arranged in the air guide plate 3 and located below the wind wheel 4, and a heat sink 7 is also arranged on the upper part of the refrigeration fin 8. The side of the refrigeration fin 8 away from the wind wheel 4 is the cooling side, and the side close to the wind wheel is the heating side. The heat exchange efficiency is improved by the heat sink. In this embodiment, a double refrigeration fin structure is provided, the wind wheel is provided above the refrigeration fin, and a semi-enclosed air guide plate structure is provided. A gap is left between the air guide plate and the side of the bottom shell 2 to form an air duct. Since in this embodiment, the wind wheel 4 is a drum structure , a number of arc-shaped fan blades are axially arranged, and since the upper shell 1 and the bottom shell 2 are both three-surrounded structures, one side is a short side and the other side is a long side, air holes are arranged on both sides of the upper shell 1 except the short side, and the number of air holes on the long side of the upper shell 1 is less than the number of air holes on the top, and air holes are arranged on both sides of the bottom shell 2 except the long side, and the number of air holes on the long side of the upper shell is less than the number of air holes on the top, so that the air flow rate on the long side is faster, forming a warm air outlet side, because the air flow rotates and circulates along the inner wall of the upper shell, the top air hole is the air inlet side, and when the wind wheel rotates, the external air enters the interior through the guidance of the air guide plate and the cooperation with the bottom shell, and the air flow blows from the side to the bottom. During the air flow, the cold air generated by the refrigeration plate will be blown out together, so that a large area of ​​refrigeration and air outlet effect can be obtained during use, thereby improving the user experience;

[0018] More specifically, a rechargeable battery 13 is arranged in the middle of the bottom shell 2, a control main board 9 is arranged on one side of the bottom shell 2, a charging and discharging management module is arranged on the control main board 9, and the control main board 9 is electrically connected to the motor 6, the cooling plate 8, and the rechargeable battery 13. In this embodiment, by setting the charging and discharging management module, the fan can be used as a power bank to charge other electronic devices, thereby improving the practicality of the fan.

[0019] To be more specific, a wind pressure plate 5 is also provided on the guide plate 3, and the wind pressure plate 5 is located below the wind wheel 4. The setting of the wind pressure plate is mainly used to change the wind direction to prevent the wind wheel from blowing wind downward, and blow the hot air and the cold air out in the same direction. When the wind direction is changed by the wind pressure plate, it will rotate inside, so that cold air can enter and blow out from the air duct.

[0020] To be more specific, a sleeve bracket 10 is provided at the end of the air guide plate 3 away from the motor 6, a shock-absorbing sleeve 11 is provided on the sleeve bracket 10, and a bearing is provided in the shock-absorbing sleeve 11 to be connected to the rotating shaft of the wind wheel 4. By providing a shock-absorbing sleeve with a bearing, the rotation of the wind wheel can be made more stable and smooth, and the wind output effect is better.

[0021] To be more specific, a function cover 14 and a bottom cover 15 are respectively provided at both ends of the upper shell 1. The function cover 14 is provided on one side of the control main board 9, and function buttons are provided thereon and electrically connected to the control main board 9. The bottom cover 15 is provided on one side of the motor 6. The operation of the fan can be controlled through the function cover. At the same time, a charging port is also provided on the function cover for easy charging.

[0022] More specifically, a lighting indicator light 12 is disposed on one side of the functional cover 14 , and the lighting indicator light 12 is electrically connected to the control main board 9 .

[0023] The working principle of the present invention is as follows: when the fan is in use, the motor 6 starts and drives the wind wheel 4 to rotate and blow air. At the same time, the refrigeration plate 8 starts to work, and it heats on one side and cools on the other side. The cooling surface faces the wind wheel 4, and the heating surface is in close contact with the heat sink 7. Since an air pressure plate 5 is provided and there are no air holes on the long side of the bottom shell 2, when the wind wheel 4 rotates, under the action of the air guide plate 3, the external air is blown downward along one side of the long side of the bottom shell 2 from the bottom air holes of the bottom shell 2, and the cold air generated by the cooling side of the refrigeration plate 8 will be blown out together. The air holes on the top of the upper shell 1 are air inlet holes, and the air holes on the long sides are hot air outlet holes. The large area of ​​cold air and hot air outlet holes can bring a better user experience. At the same time, the fan can also be used as a power bank to charge other electronic devices, thereby enriching the functionality of the fan.

[0024] The above description is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
