The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a small fan with adjustable wind direction includes a housing 1, a control panel 2 and a driving blade 3 fixedly installed in the housing 1, and the driving blade 3 can be controlled to rotate by the control panel 2, thereby achieving the purpose of fanning; the driving blade 3 can select an existing motor and blade combination structure. In this embodiment, the number of the driving blades 3 is two, thereby increasing the air volume of the small fan; in other embodiments, the driving blades 3 can also be any other number. The housing 1 is provided with an air inlet 11 and an air outlet 12, and the driving blade 3 can blow air in the direction of the air outlet 12. The air outlet 12 is provided with an air guide frame 4, which is hinged to the housing 1 and can rotate and swing along the hinge end as the axis. The air guide frame 4 is provided with a plurality of air guide plates 41, and a plurality of air outlet holes 42 are reserved between the air guide plates 41; by providing the air guide plates 41, the wind blown out by the driving blades 3 can be guided so that it is blown out in the direction of the air outlet holes 42.

[0026] When the small fan with adjustable wind direction is working, the control panel 2 controls the driving blades 3 to work, driving the blades 3 to rotate and thus causing air to flow. External air flows into the housing 1 through the air inlet 11, and then blows toward the air outlet 12 through the driving blades 3; and the wind blown out by the driving blades 3 is guided by the wind guide plate 41 so as to be blown out toward the air outlet 42. When the wind direction needs to be adjusted, the user only needs to push the wind guide frame 4 to rotate and swing along the hinged end to adjust the direction of the wind guide plate 41, thereby changing the direction of the air outlet 42; at this time, the direction of the wind blown out by the driving blades 3 also changes accordingly, achieving the purpose of adjusting the wind direction. By adjusting the direction of the wind, the different usage needs of the user can be met, thereby improving practicality.

[0027] Specifically, connecting ears 43 are respectively provided at both ends of the air guide frame 4, and the connecting ears 43 are respectively connected to the outer shell 1 in a rotatable and limited manner; through the connecting ears 43, the air guide frame 4 and the outer shell 1 are hinged and limited, and the air guide frame 4 can rotate and swing on the outer shell 1 along the connecting ears 43 as the axis, thereby changing the direction of the air guide plate 41 to achieve the purpose of adjusting the wind direction.

[0028] To facilitate adjustment, a toggle protrusion 44 is provided on the air guide frame 4. The user can push the toggle protrusion 44 to push the air guide frame 4 to rotate and swing along the connecting ear 43, thereby completing the adjustment of the wind direction. The provision of the toggle protrusion 44 improves the convenience of adjustment and enhances the user's experience.

[0029] Housing 1 houses a battery 5 and a charging connector 6. One end of charging connector 6 extends out of housing 1 and is electrically connected to control board 2. Battery 5 powers the fan, and charging connector 6 is used to charge battery 5 from an external power source. In this embodiment, charging connector 6 is a Type-C connector; in other embodiments, charging connector 6 may utilize any existing connector structure capable of charging.

[0030] The housing 1 includes a front housing 13, a bottom housing 14, and a rear housing 15. The front housing 13 and rear housing 15 are fixedly connected by screws. A middle housing 16 is fixedly mounted within the cavity formed by the front and rear housings 13, 15. The drive blades 3 are fixedly mounted on the middle housing 16. The bottom housing 14 is fixedly connected to the front and rear housings 13, 15, respectively. By configuring the housing 1 as a plurality of assembled components, it is easy to install components such as the control board 2 and the drive blades 3 into the housing 1, thereby facilitating assembly of the small fan and improving efficiency.

[0031] In this embodiment, the air outlet 12 is provided on the parting surface between the front shell 13 and the rear shell 15, the air inlet 11 is provided on the front end surface of the front shell 13, and an air inlet cover 7 is mounted on the air inlet 11 and fixedly connected to the front shell 13 by screws. The provision of the air inlet cover 7 can not only reduce the entry of dust and other foreign matter into the housing 1, but also make the small fan more beautiful as a whole, improving the user's experience.

[0032] A control switch 8 and an indicator light 9 are mounted on the bottom housing 14 and are electrically connected to the control board 2. The control switch 8 is used to turn the mini fan on and off, and can also be used to adjust the rotation of the drive blades 3, thereby adjusting the air volume. The indicator light 9 can be used to indicate the battery 5 charge level and the mini fan's operating status, thereby improving the mini fan's interactivity and enhancing user experience.

[0033] For ease of use, a bracket 10 is installed at the rear end of the rear shell 15, and the bracket 10 is hinged to the outer shell 1; by opening the bracket 10, the small fan can be placed on the table for use, which can free the user's hands and improve functionality and practicality.

[0034] To facilitate storage of the bracket 10, a receiving slot 17 is provided on the rear end of the rear housing 15. The bracket 10 is positioned in a positionally connected relationship with the receiving slot 17. Initially, the bracket 10 is positioned within the receiving slot 17, resulting in a smooth, aesthetically pleasing rear end of the rear housing 15. To support the fan, the user simply unfolds the bracket 10. The bracket 10 and the housing 1 can then be used together to place the fan on a tabletop, effectively acting as a tabletop fan. After use, the bracket 10 can be simply reclosed and stored in the receiving slot 17.

[0035] In this embodiment, lanyard holes 18 are respectively provided on the left and right sides of the shell 1; by providing the lanyard holes 18, the user can pass the lanyard through the lanyard holes 18, so that the user can conveniently carry the small fan by hand, and can also use it as a neck hanging fan, thereby improving the functionality and practicality of the small fan.

[0036] The small fan with adjustable wind direction can adjust the direction of the wind guide plate 41 by pushing and toggling the protrusion 44, thereby changing the direction of the air outlet 42 to achieve the purpose of adjusting the wind direction; moreover, the small fan with adjustable wind direction can not only be hand-held and operated, but also can be placed on the table for use through the bracket 10. In addition, by installing a hanging rope, it can also be used as a neck hanging fan, which improves the functionality and practicality of the fan, meets the user's usage needs in different scenarios, and can greatly improve the user's usage experience.

[0037] The above-mentioned specific implementation manner is a preferred implementation manner of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
