Description

Technical field

[0001] The present application relates to the field of bladeless fan technology, in particular to a foldable, tiltable bladeless fan. Background technology

[0002] The bladeless fan, also known as an air multiplier, generates a natural, continuous flow of cool air. Because it has no blades, it doesn't collect dust and poses no danger to children who might put their fingers inside. Its most notable feature is its distinctive design, characterized by a sleek and attractive appearance.

[0003] However, the bladeless fan using this technology has the following disadvantages: Non-folding design: Conventional bladeless fans typically have a fixed connection between the air outlet ring and the base, resulting in a bulky overall construction. This makes them space-consuming and impractical for transport or storage (e.g., seasonal storage at home, transport, or use in compact living spaces).

[0004] Limited airflow direction: Most bladeless fans only rotate horizontally to adjust airflow direction and cannot be adjusted vertically (upwards) or horizontally (downwards). This limits their suitability for various scenarios, such as directing airflow onto a table surface or towards higher areas.

[0005] Insufficient structural stability: In some bladeless fans with adjustable angles, the connection structure loosens after repeated adjustments, leading to instability in angle fixation and impairing the user experience. Contents of the utility model
