The installation is simple and the connection is reliable.

[0034] In this embodiment, there are four first positioning posts 14 and four second positioning posts 15, and the four first positioning posts 14 are distributed in a rectangular shape on the end face of the housing 1. In other embodiments, the number and distribution of the first positioning posts 14 and the second positioning posts 15 can be any other form, and this utility model does not limit this.

[0035] To further enhance safety, multiple protruding ribs 16 are provided on the inner wall of the protective cover 13. The protruding ribs 16 extend towards the outer wall of the housing 1 to prevent users' fingers from entering the air inlet 4, avoiding accidental injury and improving safety. At the same time, providing protruding ribs 16 on the protective cover 13 also improves the overall structural rigidity of the protective cover 13.

[0036] To facilitate adjustment of the airflow direction, a guide frame 17 is provided on the air outlet 3. The guide frame 17 is rotatably and limitingly connected to the housing 1. The guide frame 17 has multiple airflow guides 18. The guide frame 17 can rotate and swing on the housing 1 to adjust the airflow direction and meet the air delivery needs at different angles. By pushing the guide frame 17 to rotate and swing on the housing 1, the user can adjust the orientation of the airflow guides 18, thereby changing the airflow direction of the vehicle-mounted mini fan.

[0037] In use, the user can secure the car fan to the headrest rod of the front seat using the mounting ring 7. When airflow is needed to the front seats, the air outlet 3 should be directed towards the front of the vehicle; when airflow is needed to the rear seats, the air outlet 3 should be directed towards the rear of the vehicle.
