Problems solved by technology

[0003] The motor of this kind of fan device is surrounded by rubber pads or seals and is in a sealed state. The heat dissipation effect of the motor is poor and the temperature rises, which not only increases the loss of the motor, but also seriously affects its normal use; in addition, the noise of this fan device Large, the noise generated when the motor and impeller are working is easily transmitted through the air inlet of the base

Abstract

The invention relates to a bladeless fan device. The bladeless fan device comprises a base and a nozzle, wherein the nozzle is arranged on the base; the base accommodates members for generating air flow; the nozzle comprises an internal channel and an exhaust port; the air flow is jetted through the exhaust port; the nozzle extends basically orthogonally about an axis to limit an opening; and air outside the bladeless fan device is pumped by the air flow jetted from the exhaust port through the opening. The bladeless fan device is characterized in that: the members comprise a motor base, a motor and an impeller; the motor is fixed on a fixing part; the fixing part is fixed with the motor base; a shell of the motor is at least partially positioned in an air flow channel between an air inlet and an air outlet of the base; and a muffling layer is arranged on the wall of the internal channel of the motor base, or muffling layers are arranged on the internal bottom surface of the bottom of the base and the inner side walls of the four sides of the base. The bladeless fan device has the characteristics of good radiating effect, high working efficiency, low noise and the like.

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 device for generating air flow. The nozzle on the base is provided with components for generating airflow through the nozzle, the components include a motor and an impeller arranged on the motor shaft, the motor is supported by the motor base and kept in a firm state by rubber pads or seals , the nozzle of which has an internal passage for receiving an airflow from the base, and an exhaust port through which the airflow is injected, the nozzle extending substantially orthogonally with respect to the axis to define an opening through which the air outside the fan passes The opening is sucked by the air flow injected from the exhaust port. [0003] The motor of this kind of fan device is surrounded by rubber pads or seals and is i...
