Abstract

The invention discloses a bladeless fan, and relates to a fan device. The fan device comprises a base and a nozzle arranged on the base, wherein the nozzle comprises an internal channel and an air outlet; the nozzle basically extends orthogonally relative to an axis to limit an opening; and air outside the fan is sucked by airflow jetted from the air outlet through the opening. The fan device is characterized in that: the base comprises a pedestal and a support fixed on the pedestal; the nozzle is arranged on the support; the fan has a height and a width which are vertical to the axis; the width of the support of the fan is at least 10 millimeters less than that of the pedestal; the width of the pedestal of the fan is greater than 75 percent of the width of the nozzle and smaller than 125 percent of the width of the nozzle; and selectively, the nozzle, the pedestal and the support have depths along the direction of the axis, the depth of the support is at least 10 millimeters less than that of the pedestal, the depth of the pedestal is greater than 200 percent of the depth of the nozzle and smaller than 350 percent of the depth of the nozzle. The fan device can be safely and stably placed and used and has a simple and attractive structure.

Description

technical field [0001] The invention relates to a fan device. Background technique [0002] The Chinese patent application with publication number CN 101424278A (application number: 200810177843.3) published on May 6, 2009 discloses a bladeless fan for generating air flow. The nozzle, the base is provided with a member for generating the air flow through the nozzle, the nozzle has an internal channel for receiving the air flow from the base and an exhaust port, the air flow is injected through the exhaust port, the nozzle is about The axis extends substantially orthogonally to define an opening through which air external to the fan is drawn by the airflow jetted from the exhaust port. Because the nozzle of this kind of fan is relatively large and the base is small, its placement and use are not stable, and it is easy to topple over, especially when operating the fan control button arranged on the side wall of the base, so it is necessary to improve it.
