[0032] Specifically, in the present embodiment, the motor 3 is fixed at the center of the rear shell 2, the output shaft of the motor 3 is connected to the fan impeller 4, the duct circle 5 is fixedly connected between the front shell 1 and the rear shell 2, and the fan impeller 4 is accommodated in the duct circle 5; an annular air outlet 15 is formed between the duct circle 5 and the wind guide cover 12, the annular air outlet 15 is connected to the annular air outlet 13, and the annular air outlet 15 gradually decreases from the direction of the air inlet to the direction of the air outlet; an air inlet is provided on the rear shell 2, and natural wind enters the duct circle 5 through the air inlet, and after the fan impeller 4 in the duct circle 5 is accelerated to rotate, it enters the annular air outlet 13 from the annular air outlet 15.

[0033] Specifically, in this embodiment, the air duct ring 5 includes a cylindrical portion 51 and a conical cylindrical portion 52 connected to the cylindrical portion 51. The conical cylindrical portion 52 includes a cylindrical large end 521 and a cylindrical small end 522. The cylindrical large end 521 is located at one side of the front shell 1, and the outer diameter of the cylindrical large end 521 is greater than or equal to the outer diameter of the annular air outlet 13. The cylindrical large end 521 is buckled and connected to the inner side of the annular shell 11; the cylindrical small end 522 is fixedly connected to one end of the cylindrical portion 51, and the fan impeller 4 is located at the cylindrical portion 51. Inside, an annular limiting portion is provided in the shell of the rear shell 2, and the other end of the cylindrical portion 51 abuts against the annular limiting portion, and is in close contact with the circumference, so that most of the wind entering from the air inlet enters the cylindrical portion 51 and interacts with the fan impeller 4; an annular air outlet duct 15 is formed between the conical cylinder portion 52 and the wind guide cover 12, and the wind entering the handheld beauty mirror fan through the air inlet flows to the air outlet through the rotation of the fan impeller 4, and the air volume is increased through the gradually decreasing and outward expanding annular air outlet duct 15.

[0034] Specifically, in the present embodiment, the air guide cover 12 is cylindrical and concavely arranged in the annular outer shell 11. The air guide cover 12 includes a cylinder bottom 121, a conical cylinder 122 and a circular cylinder 123.

In other embodiments, the annular air inlet 24 may also be located at other positions of the circular air inlet surface, such as 1 / 4, 1 / 3, 3 / 4, 2 / 3 of the diameter of the circular air inlet surface, etc. The position of the annular air inlet is different, and the air intake effect is also different. A large number of tests have verified that when the annular air inlet 24 is located in the middle of the circular air inlet surface, the air intake effect is best.

[0038] Specifically, in the present embodiment, the recessed portion 22 is disc-shaped, the air inlet shell body 21 is ring-shaped, the outer diameter of the recessed portion 22 is equal to the inner diameter of the air inlet shell body 21, a step is formed between the recessed portion 22 and the air inlet shell body 21, and the annular air inlet 24 is located on the side of the step, that is, the opening position of the annular air inlet 24 is perpendicular to the axis of the handheld beauty mirror fan. Viewed from the back of the handheld beauty mirror fan, the annular air inlet 24 is in a hidden state, with a high aesthetics, and small objects and the user's hair are not easy to enter the fan, which greatly reduces the safety hazards during use.
