[0026] The technical solution of this utility model will be further clearly and completely described below with reference to the accompanying drawings and through embodiments. The described embodiments are only some embodiments of this utility model. Other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this utility model.

[0027] like Figure 1-6 As shown, a multifunctional handheld fan includes a housing 1 and a handle 2 located at the bottom of the housing 1. The housing 1 has an air outlet 11 on the front and an air inlet 12 on the back. The housing 1 has an air duct 13 connected to the air outlet 11 and the air inlet 12. A high-speed fan 3 is installed in the air duct 13. The handle 2 has a negative ion generator 4, a battery 8, and a first PCB board 5. The negative ion generator 4 has an air outlet pipe 41 for releasing negative ions. The air outlet pipe 41 is connected to the air duct 13. The first PCB board 5 is electrically connected to the high-speed fan 3, the negative ion generator 4, and the battery 8. In use, the high-speed fan 3 rotates, causing air to flow. The air enters through the air inlet 12, carries negative ions, and is blown out through the air outlet 11. It can not only purify the air and cool the hair as a handheld fan, but also be used as a hair dryer. By using the high-speed fan 3 to enhance the airflow, it has excellent hair drying ability. It uses negative ions to reduce static electricity, smooth frizzy hair, and make the hair soft and easy to comb.

[0028] The high-speed fan 3 consists of an existing high-speed motor and fan blades. The wind force of the high-speed fan 3 can be controlled by the first PCB board 5 to achieve different functions.

[0029] like Figure 5As shown, an air outlet cover 14 is installed inside the air outlet 11. A ventilation opening 141 is provided in the middle of the air outlet cover 14. A mounting base 1411 is provided in the middle of the ventilation opening 141. A lighting device 6 is provided inside the mounting base 1411. The lighting device 6 is used for illumination and can be made of existing LED lights, etc. A light-transmitting protective mirror 1412 is also provided on the mounting base 1411 on the front of the lighting device 6. The light-transmitting protective mirror 1412 is used to protect the lighting device 6. The light-transmitting protective mirror 1412 can be made of existing transparent materials such as glass or transparent plastic.

[0030] like Figure 5 As shown, an air inlet screen 15 is installed inside the air inlet 12, which can prevent foreign objects from entering the air duct 13.

[0031] like Figure 4 As shown, a nozzle 16 is detachably provided at the air outlet 11. The outer shell 1 has a tubular structure. Correspondingly, a tubular connecting part 161 is provided on the back of the nozzle 16. The inner diameter of the tubular connecting part 161 is adapted to the outer diameter of the outer shell 1. The tubular connecting part 161 is detachably sleeved on the outer shell 1 outside the air outlet 11. The nozzle 16 can be set into different shapes according to different user needs.

[0032] like Figure 4 As shown, the inner wall of the tubular connecting part 161 is provided with a plurality of strip grooves 1611. Both ends of the strip grooves 1611 are connected to the outside. This is to prevent the tubular connecting part 161 from being difficult to detach from the outer shell 1 when the tubular connecting part 161 is sleeved on the outer shell 1 due to the relatively smooth surfaces of the two, which would affect the user's replacement of the nozzle 16.

[0033] like Figure 5 As shown, a display screen 51 is provided on the first PCB board 5. The display screen 51 is used to display the working status of the fan, such as: power, power (or speed) of the high-speed fan 3, etc.

[0034] like Figure 5 As shown, an encoder 52 is provided on the first PCB board 5. The encoder 52 is used to linearly adjust the working power of the high-speed fan 3 to adjust the wind speed of different strengths. The user only needs to turn the roller on the encoder 52 when the working circuit is connected.

[0035] like Figure 5 As shown, a power button 53 is provided on the first PCB board 5 for controlling the power on or off. The power button 53 can be an existing tactile button or other components.

[0036] like Figure 5As shown, the handle 2 also contains a second PCB board 7, which has a bidirectional TYPE-C interface 71. The TYPE-C interface 71 can charge the battery 8 and also charge external electronic devices. The second PCB board 7 can manage and control the charging and discharging status of the battery 8.

[0037] like Figure 5 As shown, the second PCB board 7 is also provided with a lighting button 72 for controlling the lighting device 6 to turn on or off. The lighting button 72 can be an existing tactile button or other components. The second PCB board 7 is electrically connected to the lighting device 6 and to the first PCB board 5.

[0038] like Figure 6 As shown, the outer shell 1 includes a tubular shell 101. A slide rail 1011 protrudes from the bottom of the inner wall of the tubular shell 101. A top shell 102 and a bottom shell 103 are inserted into the tubular shell 101. The top shell 102 and the bottom shell 103 are interlocked and fixed to form a first cavity. The air duct 13 is disposed in the first cavity. The air outlet 11 and the air inlet 12 are respectively disposed on the front and back of the first cavity. A groove 1031 is recessed on the bottom outer wall of the bottom shell 103. The slide rail 1011 is slidably disposed in the groove 1031. By setting the tubular shell 101, the top shell 102 and the bottom shell 103, the outer shell 1 uses fewer fasteners such as screws, reducing weight and making installation more convenient.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
