Title:
BLADELESS FAN AND AIR OUTLET CYLINDER THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/196437
Kind Code:
A1
Abstract:
A bladeless fan and an air outlet cylinder thereof. The air outlet cylinder comprises an air cylinder (1) and a nozzle (2); the air cylinder (1) is provided with an air inlet (11) for receiving airflows, and an internal channel (12); the front-end sidewall of the air cylinder (1) is provided with an opening (13) extending longitudinally therethrough; the inner wall surface at each of two sides of the opening (13) in the air cylinder (1) is separately provided with a limiting groove (14) extending longitudinally therethrough; the nozzle (2) comprises a mouth part (21) embedded in the opening (13), and two airflow guiding parts (22, 23) respectively embedded in the corresponding limiting grooves (14); multiple air outlet slits (211) positioned on the same straight line are longitudinally spaced on the mouth part (21); airflows received in the internal channel (12) are outwards sprayed from the air outlet slits (211) by virtue of the guiding effect of the two airflow guiding parts (22, 23). The bladeless fan comprises a base, and the air outlet cylinder supported by the base. The air outlet cylinder facilitates centralization of airflows for outward spraying to improve the wind power of the fan and increase an effective air supply distance, and furthermore, has advantages such as a fast airflow flowing speed, uniform spraying, a high air volume, low noise, a novel and beautiful shape, less occupied space, and convenience in manufacturing.
