Abstract
A fan designed for directed airflow towards a target object. The fan includes a fan body producing an airflow and an airflow adjusting module that adjusts the airflow speed based on the distance to the target object. The airflow adjusting module includes a first sensor for distance measurement, a variable hood with a variable opening, and a controller. The controller, connected to the first sensor and the variable hood, regulates the variable opening size in response to distance information. The fan's adaptive airflow control ensures consistent air strength for the target object, adapting to varying distances.
Claims17
A fan comprising:
- a fan body configured to output an airflow;
- and
- an airflow adjusting module disposed on the fan body, the airflow adjusting module configured to change a speed of the airflow based on a distance between a target object and the fan body, the airflow adjusting module comprising:
- a first sensor configured to sense the distance between the target object and the fan body;
- a variable hood disposed on the fan body, the variable hood defining a variable opening configured for facilitating the airflow through the airflow adjusting module;
- and
- a controller electrically connected to each of the first sensor and the variable hood, the controller configured to control the variable hood to adjust a size of the variable opening based on the distance sensed by the first sensor.
