[0049] In the embodiment, the bottom of the handle 13 and located at the right side of the charging base 16 is provided with a connecting hole, and an expansion thread sleeve 18 is embedded in the inside of the connecting hole.

[0050] It should be noted that the expansion thread sleeve 18 is a 4 / 1 threaded hole, and since the wind power generated by the 13 million revolutions motor reaches the 16 typhoon level, it can be used with various supports, so that the product can be stably fixed in a certain place.

[0051] Specifically, the expansion thread sleeve 18 provides more use flexibility for the fan, and the user can connect the fan with various expansion supports such as desktop supports, vehicle supports, tripods, etc. through the expansion thread sleeve 18. In this way, the user can fix the fan at a suitable position in different scenes such as desktop, vehicle, outdoor, etc., realize hands-free use, and facilitate the user to enjoy the convenience brought by the fan while performing other activities.

[0052] The working principle of the above embodiment is as follows:

[0053] (1) When inflating inflatable devices such as inflatable pads, inflatable tents or kayaks, connect the air inlet nozzle 21 to the air outlet nozzle 111, start the fan, and the motor 122 drives the fan blades 123 to rotate at high speed. Under the push of the fan blades 123, the airflow is sent into the inflatable device through the air duct 11, the air outlet nozzle 111 and the air inlet nozzle 21, thereby realizing the inflation function.

[0054] (2) When cleaning dust, connect the brush air outlet nozzle 22 to the air outlet nozzle 111, and turn on the fan. The motor 122 drives the fan blades 123 to rotate to generate airflow, which is blown out through the air duct 11, the air outlet nozzle 111 and the brush air outlet nozzle 22; at the same time, the airflow drives the brush on the brush air outlet nozzle 22 to move, and the brush can more effectively clean dust under the assistance of the airflow, realizing the blowing and brushing effect.

[0055] (3) When the fan is running, the motor 122 and the PCB board 15 and other components will generate heat. Part of the airflow generated by the rotation of the fan blade 123 enters the air duct 131 inside the handle 13 from the air inlet 133 of the air duct 11, and then is discharged from the heat dissipation air outlet hole 132. This airflow flow process can take away the heat generated by the PCB board 15 and the battery 14 and other components inside the handle 13, realize the heat dissipation effect, and ensure the stable operation of the fan.

[0056] (4) When the fan is used at night or in a relatively dark environment, turn on the light-emitting part 124. After the lamp plate 1242 is powered on, light is emitted. The light is uniformly irradiated to the surrounding environment through the lampshade 1243. When cleaning, the light can illuminate the dust, making the dust more obvious, facilitating the user to blow dust and clean, and also providing lighting for night activities.

[0057] (5) When the fan needs to be fixedly used on the desktop or in the car and the like, the expansion thread sleeve 18 is connected with the matching expansion bracket. The expansion bracket can be a desktop bracket, a vehicle-mounted bracket, etc. The bracket is tightly matched with the expansion thread sleeve 18 through rotation or the like, so that the entire handheld fan is fixed at the specified position, facilitating the user to stably use the fan in different scenes.

[0058] It should be noted that, in this text, relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the element defined by the statement "includes a" does not exclude the presence of another identical element in the process, method, article or equipment that includes the element.

[0059] If this patent discloses or involves mutually fixedly connected parts or structural members, unless otherwise stated, the fixed connection can be understood as: detachable fixed connection (for example, connected by bolts or screws), and can also be understood as: non-detachable fixed connection (for example, riveting, welding), of course, the mutually fixed connection can also be replaced by an integral structure (for example, manufactured by integral forming process) (obviously, integral forming process cannot be used).

[0060] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application.
