In a specific embodiment, when an external air flow enters the bladeless fan, the driving device inside the bladeless fan drives the air flow to flow upwards to enter the air duct 115 formed by the front shell 110 and the rear shell 120, because the nozzle lining plate 131 is arranged in the vertical section 114 of the front shell 110 and is in a V shape, the air flow enters from a large opening of the V shape and is discharged from a small opening, and the nozzle lining plate 131 is arranged to avoid squeal caused by unsmooth air flow circulation due to roughness and frightening of the front shell 110 and generate noise; furthermore, because the flow guide front part 1321 and the flow guide rear part 1322 form a closed flow guide surface, the front part of the nozzle 111 and the nozzle lining plate 131 form a left flow guide air duct 1331 and a right flow guide air duct 1332, and because the nozzle lining plate 131 is V-shaped, along the movement direction of the air flow, the left flow guide air duct 1331 and the right flow guide air duct 1332 are continuously reduced, so that the sound pressure level of the noise of the whole machine is reduced, the air outlet is softer, the user experience is improved, and the flow guide surface enables the air flow sprayed out by the nozzle 111 to be formed by mixing the air flows in at least two directions.
Since the angle of the nozzle liner 131 is smaller than that of the front case 110, the inner space of the air duct 115 is reduced, and when air flows enter the air duct 115 at a high speed, a pressure difference is generated, so that the air discharged from the bladeless fan flows vigorously, and the discharge of the air flow is accelerated.
As shown in fig. 7, at least two hooks 1313 are disposed between the air outlets 1315, and the cross-sectional area of the hooks 1313 gradually decreases along the protruding direction thereof; a clamping groove 1317 is formed between the clamping hooks 1313, wherein the clamping groove 1317 is matched with the spacing structures 112 between the nozzles 111 arranged at intervals in pairs, and the clamping groove 137 is matched with the spacing structures 112 between the nozzles 135 arranged at intervals in pairs, so that the nozzle liner plate 131 is further fixed while being fixed on the front shell 110 by using the locking structure 1314, the stability of the nozzle liner plate 131 is improved, and the service life of the nozzle liner plate 131 is prolonged.
