Problems solved by technology

[0003] One of the disadvantages of using fan blades to blow out the wind is that the wind force of the air outlet device is too scattered. For the traditional fan outside the air outlet device, this shortcoming is not obvious, but for the built-in fan of the air outlet device, due to the The air flow must pass through an air duct and then be blown out by the nozzle, so the wind force of the air outlet device must be concentrated, otherwise the wind resistance will be too large, resulting in excessive energy loss

Abstract

The invention discloses an air-out device for a fan, belonging to the technical field of fans. The device comprises a motor and a wind wheel, wherein the wind wheel is fixed on a motor shaft; and the motor is fixed on a motor fixing seat. The wind wheel is adopted for air output, the wind force of the air-out device for the fan is relatively concentrated, thus air flow can pass through smoothly in an air duct, and too large wind resistance can not be caused.

Description

technical field [0001] The invention belongs to the field of fans, in particular to an air outlet device for fans. Background technique [0002] Fans have been widely used in the market, and traditional fans include an air outlet device composed of a fan blade and a motor. The rotation of the fan blades makes the air flow toward the user to generate wind. When the weather is hot, the heat generated on the surface of the human body can be carried away by the wind, making people feel cool. Because the structure of the fan is simple, the price is low and its power consumption is also greatly reduced relative to the air conditioner, so the fan still has a wide market. [0003] One of the disadvantages of using fan blades to blow out the wind is that the wind force of the air outlet device is too scattered. For the traditional fan outside the air outlet device, this shortcoming is not obvious, but for the built-in fan of the air outlet device, due to the The air flow must pass...
