<p>A nozzle of a bladeless fan comprises a nozzle body (1). The nozzle body (1) is provided with a receiving port (2) used for receiving basic air-flow, an internal channel (3), and an air guide port (4) used for guiding external air. A narrow strip-shaped opening (41) is arranged at the front end of the air guide port (4). A wide opening (42) is arranged at the rear end of the air guide port. Exhaust ports (5, 6) are provided on the surface of the head body (1), arranged along the periphery of the narrow strip-shaped opening (41). The basic airflow received by the internal channel (3) is jetted out from the exhaust ports (5, 6). The nozzle of the bladeless fan is designed to be approximately cylindrical in order to occupy a smaller area when in use. Meanwhile, air volume is increased by the trumpet-shaped structure of the air guide port having the narrow front end and the wide rear end.</p> |
