Abstract

The invention discloses a fan. The fan comprises an intake grid structure arranged in an air inlet of the fan; the intake grid structure comprises blades configured as long structures; the blades extend in the radial direction of the air inlet; and the angles of air guide surfaces of the blades are adjustable. Through adjustment of the angles of the air guide surfaces of the blades, the fan controls the intake quantity (comprising the airflow quantity and the airflow speed of fed air) to achieve the effect of controlling the exhaust quantity (comprising the airflow quantity and the airflow speed of exhausted air) so as to meet different demands of users and to improve the user experiences.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a fan. Background technique [0002] At present, the air intake angle of the air intake grille of most fans in the market is fixed and cannot be adjusted. The air intake angle of the air intake grille has a certain influence on the air output of the fan. At the same speed, the motor has a large air output and a long air supply distance; when the air intake grille is at a certain angle to the surface where the air inlet is located, the motor has a smaller air output and a short air supply distance at the same speed. However, the fan intake grills currently on the market cannot adjust the air output volume of a single fan. Contents of the invention [0003] In view of this, the object of the present invention is to provide a fan, which can meet different needs of users by adjusting the angle of the air guiding surface of the blade. [0004] In order to achieve the above object, on...
