Description

Technical Field

[0001] This utility model belongs to the technical field of electric fans, and specifically relates to a suspended electric fan equipped with a tilting bracket. Background Technology

[0002] An electric fan, also known as a fan or ventilator, is a household appliance that uses an electric motor to drive the fan blades to rotate, thereby accelerating air circulation. It is primarily used for cooling and air circulation. Currently, the tilt angle adjustment mechanism of most traditional electric fans consists of a connector, metal clips, positioning beads, positioning pins, springs, torsion springs, bolts, and nuts. The connector has a countersunk hole for the positioning pin, and the metal clips have positioning holes. This structure has the following drawbacks: First, the angle positioning relies on the positioning holes on the metal clips, resulting in limited angle adjustment and no stepless adjustment. Second, the torsion springs, positioning beads, and other components are difficult to assemble in the workshop. Third, due to the small friction area, long-term tilting operation can cause wear and tear on the positioning holes, leading to positioning failure. Fourth, this mechanism imposes many limitations on the shape of the fan head and body connection, making many aesthetic designs difficult to achieve. Furthermore, automated control is challenging. How to achieve automatic tilt angle adjustment is a research direction for those skilled in the art.

[0003] In the pitching process of an electric fan, to expand the airflow range, a deflecting head structure or a rotating base structure is generally used. A deflecting motor at the connection between the pitch support and the head controls the head to deflect along the center of the pitch support, achieving a large-scale deflection of the head for airflow, thus expanding the airflow range. Alternatively, a rotating motor is installed inside the base, controlling the rotation of the column and the head to achieve a large-scale rotation of the head for airflow, thus expanding the airflow range. The former method, while achieving left-right deflection of the head, struggles to automatically control the up-down deflection adjustment of the pitch support. The latter method, while capable of up-down adjustment of the pitch support, requires controlling the left-right deflection of the entire head and column, resulting in high motor power consumption. Therefore, achieving automatic left-right and up-down deflection of the head is a research direction for those skilled in the art. Summary of the Invention
