The design of the housing 1 of this embodiment enables the handheld fan to have a grip portion 11 and a blowing portion 12, and an angle is formed between the two. Such a design conforms to the principle of ergonomics, so that the user can hold the fan more comfortably and reduce hand fatigue. At the same time, the angle design also makes the fan more stable, and the user can better control the wind direction and wind force. Secondly, the blowing channel 13 and the air guide channel 14 that are interconnected are arranged inside the housing 1. The air guide channel 14 is located inside the gripping portion 11, and the air blowing channel 13 is located above the air blowing portion 12. Such a layout is conducive to effectively guiding and distributing wind force. Through the provision of the air guide channel 14, the wind force can be more evenly distributed to the air blowing portion 12, thereby enhancing the air blowing effect of the fan. In addition, the housing 1 is provided with a first air inlet 15 on one side of the air blowing channel 13.

By placing the control board 4 on the first placement groove 141 and the power supply 5 on the second placement groove 142, the internal space of the fan can be effectively utilized, so that the control board 4 and the power supply 5 are fixed in appropriate positions. Such a design simplifies the assembly and maintenance process of the fan and improves the reliability and stability of the fan. The air guide gap provided between the control board 4 and the power supply 5 helps to dissipate heat and prevent short circuits. The fan will generate a certain amount of heat when working. By providing the air guide gap, air circulation can be promoted, heat dissipation can be helped, and the normal operating temperature of the control board 4 and the power supply 5 can be maintained. At the same time, the air guide gap also serves to isolate the control board 4 and the power supply 5, reducing the risk of possible short circuits and improving the safety of the fan. The placement slot design on both sides of the wind guide channel 14 also helps to optimize the guidance and distribution of wind. By placing the control panel 4 and the power supply 5 on both sides of the wind guide channel 14, the wind can be better guided through the wind guide channel 14 to achieve a more uniform and stable wind output effect.

[0034] The bottom of the air guide channel 14 is provided with a bottom cover 143, and the bottom cover 143 is provided with a second air inlet 144, and one end of the second air inlet 144 is connected to the air guide gap. In this embodiment, the setting of the bottom cover 143 can close the bottom of the air guide channel 14, increasing the structural integrity and stability of the fan. As the bottom cover of the air guide channel 14, the bottom cover 143 can effectively protect the internal components from the invasion of external dust and debris, and reduce the risk of damage to the internal components of the fan. The setting of the second air inlet 144 allows the fan to obtain fresh air from the bottom. The second air inlet 144 is located on the bottom cover 143, and can introduce external air and send it into the air guide channel 14. Such a design can increase the airflow of the fan, improve the wind output effect, and make the heat dissipation effect of the fan better when working. At the same time, the communication between the second air inlet 144 and the air guide gap helps to guide external air into the air guide channel 14, and is connected to the air guide gap between the control board 4 and the power supply 5 through the air guide gap. This design can promote air circulation, help the control board 4 and the power supply 5 to dissipate heat, maintain their normal operating temperature, and improve the reliability and stability of the fan.

[0035] The control panel 4 is provided with a plug-in interface 41, and the bottom cover 143 is provided with an interface fixing groove 42. One end of the plug-in interface 41 extends to the interface fixing groove 42 and is fixed by the interface fixing groove 42. The plug-in interface 41 is used for charging the power supply 5. Specifically, the bottom cover 143 is provided with an extension platform 145, one end of which extends into the air guide channel 14, and one side of the extension platform 145 is provided with a support rib 146, and the support rib 146 is used to support one side of the control panel 4. In this embodiment, through the design of the plug-in interface 41 and the interface fixing groove 42, the power supply 5 can be conveniently inserted into the plug-in interface 41 for charging, and through the fixation of the interface fixing groove 42, the stability and safety of the charging connection can be ensured. Through the design of the extension platform 145 on the bottom cover 143, one end of the extension platform 145 extends into the air guide channel 14, and one side is provided with a support rib 146, which can provide support for the control panel 4 and increase the stability and reliability of the control panel 4.

[0036] The angle formed between the grip portion 11 and the blowing portion 12 is 70° to 120°. In the present embodiment, the angle formed between the grip portion 11 and the blowing portion 12 is preferably 90°, which can provide a comfortable holding experience. This angle range can adapt to the holding habits and hand shapes of different users, reduce the pressure and discomfort when holding, and enable the user to hold the fan for a long time without feeling tired. The choice of angle can also provide convenient operation and control. The appropriate angle allows the user to easily control the direction and angle of the fan, and adjust the position and range of the blowing to meet different needs. Such a design allows users to use the handheld fan more freely and get a better wind experience.

[0037] An installation channel 23 is provided in the fixed bracket 2, and the high-speed fan 3 is arranged in the installation channel 23.

Placing the high-speed fan 3 in the installation channel 23 can optimize the air flow. By installing the high-speed fan 3 in a reasonable position, the wind blown out by the fan can be made more concentrated and powerful, providing a better wind output effect. Such a design can enhance the wind force of the fan, improve the cooling effect and ventilation performance.

[0038] The front end of the fixed bracket 2 is provided with an inner bracket 24, and the inner bracket 24 is used to install the high-speed fan 3. One end of the inner bracket 24 is provided with a mounting platform 241, and the air outlet slot 25 is provided on the outside of the mounting platform 241. In this embodiment, by providing the inner bracket 24 and the mounting platform 241 at the front end of the fixed bracket 2, a stable installation position can be provided for the high-speed fan 3. The inner bracket 24 can ensure that the high-speed fan 3 is correctly installed on the mounting platform 241 to prevent it from shaking or shifting during use, thereby ensuring the normal operation and safe use of the fan. The air outlet slot 25 is provided on the outside of the mounting platform 241, so that the air outlet of the high-speed fan 3 can be directly guided and concentrated through the air outlet slot 25. Such a design can enhance the air outlet effect of the fan, make the wind force more concentrated and powerful, and provide better cooling and ventilation effects.
