Abstract

The invention provides a combined type fan which comprises a tower fan body, a rotating fan and a drive assembly. The rotating fan is hinged onto the upper end surface of the tower fan body; the driveassembly is arranged in the tower fan body; the drive end of the drive assembly is acted on the rotating fan so as to drive the rotating fan to rotate; the drive assembly comprises a motor, a drivengear and an ejector rod; the motor is arranged in the tower fan body; a drive gear is arranged on a motor shaft of the motor; the driven gear meshes with the drive gear; the ejector rod is arranged onthe driven gear and rotates along with the driven gear; and the ejector rod is acted on the rotating fan so as to drive the rotating fan to rotate. According to the combined type fan provided by theinvention, the rotating fan is hinged to the upper end part of the tower fan body, and in addition, under the action of the drive assembly, an air opening of the rotating fan can rotate relative to the tower fan body, so that an air outlet angle is changed, an air outlet direction is increased, and particularly, the problem that an air outlet range of an original tower fan in the height directionis inflexible is solved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a combined fan. Background technique [0002] The tower fan "throws" the wind out through the cross-flow fan to form an airflow—the wind pressure is generated by the rotation of the wind wheel to generate centrifugal wind force, and finally the wind force is transmitted out through the internal air guide wall. Since the cross-flow wind wheel is generally cylindrical, the tower fan is used to obtain a three-dimensional air flow wall, or "air curtain", which is perpendicular to the ground and blows from side to side. In addition, the cross-flow wind wheel has many blades, so the air supply is uniform and soft, which is very close to the natural wind, so it is deeply loved by consumers for its soft wind. [0003] Among them, the use environment of the tower fan is mostly the living room of the consumer. In this environment, the consumer is mostly in a sitting or lying ...
