The invention discloses an air supercharging device of a bladeless fan. The air supercharging device of the bladeless fan is mainly composed of an air inlet cover (31), a shell body (32), a dust cover (33), a filter net (34), a turbocharger (35), a motor (36), a storage box (37), and an air conveying pipe (38). A second air nozzle is arranged in an outer shell of the air supercharging device so that even the middle part of the bladeless fan can provide air flow blown to a user, and therefore the phenomenon that wind power in the middle of the bladeless fan is weak is effectively avoided.
