Technical Field

[0001] This utility model relates to the field of fan technology, and more specifically, to a multifunctional fan. Background Technology

[0002] A fan is a device that generates airflow by driving blades to achieve functions such as ventilation, cooling, and air exchange. Its core function is to reduce the perceived temperature of the human body through airflow or to improve air quality by accelerating air circulation. Modern fans are also often equipped with functions such as speed adjustment, timer, oscillation, and intelligent control (such as remote control and voice control) to enhance ease of use and comfort. In modern home life, fans are a commonly used cooling device with increasingly diverse usage scenarios.

[0003] However, existing fans have the following problems when in use:

[0004] Most fans only have a single standing or wall-mounted form, which cannot be flexibly switched according to different usage scenarios. For example, it is difficult to meet the needs of using it on the floor in the bedroom and installing it on the wall in the kitchen. In addition, the bottom support rod and the fan body are mostly integrated into one design, which takes up a lot of space when stored, is inconvenient to store, and affects the tidiness of the home space.

[0005] This utility model can freely switch between vertical and wall-mounted modes through the structure of bolts and connecting rods to meet the needs of different scenarios; the anti-slip textured bolts are easy to operate and enhance stability, while also being easy to disassemble, clean and store, combining practicality and flexibility.
