Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A flashlight fan includes a housing comprising an upper shell 1 and a lower shell 2 that are connected to each other. One end of the housing is formed as a handle, and the other end is formed as a fan housing cavity. An inner shell 5 is disposed inside the fan housing cavity, and a mounting base is disposed on the inner shell 5. The side of the mounting base facing the handle is configured as a fan base 51. A fan blade assembly 6 is mounted on the fan base 51. An air inlet 10 and an air outlet 33 are provided on the wall of the fan housing cavity. The fan blade assembly 6 guides air located at the air inlet 10 into the fan housing cavity and blows it outward from the air outlet 33. A lamp holder 52 is disposed on the side of the mounting base away from the fan base 51. An illumination mechanism 4 is disposed on the lamp holder 52. The light emitted by the illumination mechanism 4 is directed outward toward the end of the fan housing cavity away from the handle.

[0023] The fan housing cavity is open at the end furthest from the handle. A port cover 3 is installed on the open end. The port cover 3 is located in the projection area of ​​the lamp holder 52 and has an illumination through hole 31 that penetrates the inside and outside of the fan housing cavity. The lighting mechanism 4 includes a lamp plate 43, a reflector cup 42, and a light-transmitting plate 41. The lamp plate 43 is mounted on the lamp holder 52 and has light-emitting LEDs encapsulated on it. The reflector cup 42 covers the light-emitting LEDs. The light-transmitting plate 41 is located at the end of the reflector cup 42 furthest from the lamp plate 43 and is used to encapsulate the illumination through hole 31.

[0024] The inner shell 5 is a tubular body. The mounting base is disposed inside the inner shell 5 and is coaxially arranged with the inner shell 5. The circumferential portion of the mounting base extends towards the inner wall of the inner shell 5 to form a booster blade 53. One end of the booster blade 53 facing the inner shell wall is connected to the inner shell 5. Multiple booster blades 53 are provided, and the multiple booster blades 53 are evenly arranged around the circumference of the mounting base. The lighting through hole 31 is coaxially arranged with the port cover 3.
