In this implementation, a spacer device 43 is arranged between the first mounting part 41 and the second mounting part 42, and the spacer device 43 is composed of several uniformly distributed partition plates 431. Through the above structure, due to the arrangement of the several uniformly distributed partition plates 431, and due to the fact that the first mounting part 41 is provided with the air blowing assembly 2 and the second mounting part 42 is provided with the power supply assembly 3, there is a certain space between the air blowing assembly 2 and the power supply assembly 3, which can prevent heat generated by the battery in the power supply assembly 3 from affecting the air blowing assembly 2 and help to prolong the service life of the fan.
In this implementation, the second mounting part 42 is provided with a mounting chamber 421; the power supply assembly 3 includes a circuit board 31 and a battery 32; the circuit board 31 is electrically connected to the battery 32; and both the circuit board 31 and the battery 32 are arranged in the mounting chamber 421. Through the above structure, since both the circuit board 31 and the battery 32 are arranged in the mounting chamber 421, it is beneficial for making the structure compact, reducing a mounting space and the production cost, and facilitating the user to carry the portable fan. In particular, the spacer device 43 comprises an annular plate 441 and two side plates 442, the annular plate 441 projects toward the power supply assembly 3, and the annular plate 441 and the two side plates 442 cooperatively form the mounting chamber 421. In addition, the first mounting part 41 includes an annular sidewall 410, and a height of spacer device 43 along a first direction from the first air inlet 11 to the air outlet 12 is greater than a height of the annular sidewall 410 along the first direction, such that the annular plate 441 and the housing 1 can cooperatively form the first air guide chamber 13.
In this implementation, an upper part of the housing 1 is provided with a clamping slot 14; the first mounting part 41 is provided with a limiting protrusion 415; and the limiting protrusion 415 presses against the clamping slot 14, so that the mounting shell 4 is partially located inside the first air guide chamber 13. Through the above structure, the first mounting part 41 can be clamped and sleeved inside the housing 1, and the air outlet hood 411 can expose the air outlet 12, which is convenient for the fan to blow out the air and improves the user experience.

Specifically, the first clamping device 7 is a first clip 71; and the first clip 71 presses against the front panel 101 to form a first clamping space 711 between the first clip 71 and the front panel 101. The first clip 71 can be a metal or plastic clip. Through the above structure, during use, the user can clamp the fan at the waist of pants or a pocket of clothes through the first clip 71, so that the fan blows air into the body of the user. Compared to a traditional small handheld fan, the fan with the clip can free the hands. When working, the user can feel the air blown out from the fan without holding the fan, thus achieving a cool experience. This greatly improves the portability and practicality of the product.
In this implementation, the air inlet hood 6 is connected to a second clamping device 8; and the second clamping device 8 is configured to clamp the portable fan onto clothes of a user.

The second clip 81 can be a metal or plastic clip. Through the above structure, during use, after clamping the portable fan to the waist of pants with the first clip 71, the user can clamp the second clip 81 to a hem, thereby achieving an effect of stabilizing the fan. When the user needs to do large body movements due to work, the fan can still be firmly fixed at the waist of the pants, which greatly ensures the stability of the fan.
In this implementation, a surface of the housing 1 is further provided with a first hook 105 and a second hook 106; a first hook hole 1051 is formed between the first hook 105 and the left panel 103; and a second hook hole 1061 is formed between the second hook 106 and the right panel 104. Through the above structure, when it is inconvenient for the user to clamp the fan onto the clothes, the user can thread a rope through the first hook hole 1051 and the second hook hole 1061, and then hang the rope around the neck, so that the fan can be carried without being held by the hands, and the portability of the fan is improved.
In this implementation, the housing 1 is further provided with an on/off button 9; the on/off button 9 is electrically connected to the air blowing assembly 2 and the power supply assembly 3; the air inlet hood 6 is connected to a button mounting part 62; the button mounting part 62 is provided with a button mounting hole 621; the on/off button 9 is located at the button mounting hole 621; the lower end of the housing 1 is provided with a first mounting port 15, an inwards protruding button mounting slot 16, and a second mounting port 17; the button mounting part 62 can be clamped into the button mounting slot 16; the first mounting port 15, the button mounting hole 621, the button mounting slot 16, and the second mounting port 17 are communicated to each other in sequence; and the on/off button 9 is further provided with a fan gear indicator lamp 91 and a charging indicator lamp 92.
