Description

Technical Field

[0001] This utility model relates to the field of ceiling fan technology, specifically a lifting ceiling fan with a locking function. Background Technology

[0002] Ceiling fans are electric fans that are fixedly installed on the ceiling. They are driven by an electric motor and have rotating blades. The fan generates airflow through the rotating blades to achieve a cooling effect. They are energy-efficient, reducing electricity costs, and have multiple speed settings. Ceiling fans can also be integrated with lighting equipment to provide both lighting and ventilation. Some high-end ceiling fans are also equipped with remote controls and smart control systems for easy operation. When installing a ceiling fan, it is necessary to select the appropriate model based on the room height and area, and ensure that the ceiling structure is sturdy. Ceiling fan maintenance includes regularly cleaning the blades and motor, as well as promptly checking and repairing any abnormal noises or instability during operation.

[0003] According to patent number CN107859642A published on the China Patent Network, the patent title is "A Ceiling Fan." This ceiling fan uses an electromagnet to fix the fan blades. The fan blades have a push-button design at a specific position. When the ceiling fan is powered on, the electromagnet works synchronously, generating an inductive magnet that completely attracts the screwless fan blades. When the ceiling fan is powered off, the electromagnet loses its magnetism. If the fan blades need to be replaced, they can be easily removed by simply pressing the push-button switch. However, this ceiling fan does not have an automatic lifting and locking function. Traditional ceiling fans do not have a lifting mechanism and cannot adjust and lock the height of the ceiling fan according to the height of the ceiling, resulting in unstable airflow and reducing the applicability of the ceiling fan.

[0004] Therefore, the ceiling fan needs to be redesigned to have an automatic lifting and locking function. Utility Model Content
