Tower fan oscillating mechanism and tower fan

Abstract

The invention discloses a tower fan oscillating mechanism and a tower fan. The tower fan oscillating mechanism is used for enabling a machine body of the tower fan to rotate relative to a base and comprises a first gear, a second gear and a driving device, wherein the first gear meshes with the second gear, the driving device is used for driving the first gear to rotate and is fixed relative to the machine body, the second gear is fixed relative to the base, and the first gear rotates under the action of the driving device and rotates around the second gear so as to drive the driving device and the machine body to rotate together relative to the base. The tower fan oscillating mechanism has the advantages that gear mechanisms are adopted, assembly is simple, motion is smooth, reversing is easy, particularly, dead point positions do not exist in the motion process of the gear mechanisms, and therefore the problem that in the prior art, when a crank-rocker mechanism is adopted, the crank-rocker mechanism is prone to being clamped can be avoided.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a tower fan oscillating mechanism and a tower fan with the same. Background technique [0002] Tower fan is a new type of fan currently on the market. It is favored by consumers due to its unique column shape and small footprint during use. In order to realize the function of shaking the head to blow air, the fuselage of the tower fan needs to rotate relative to its base, so an oscillating mechanism needs to be provided between the fuselage and the base of the tower fan. [0003] In the prior art, the oscillating mechanism of the tower fan generally adopts a planar four-bar linkage mechanism, such as a crank rocker mechanism. This oscillating mechanism has defects such as low assembly efficiency and easy jamming of the dead point of the crank rocker after long-term movement. [0004] In addition, due to the thin and tall characteristics of the tower fan itself, and ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the oscillating mechanism of the tower fan generally adopts a planar four-bar linkage mechanism, such as a crank rocker mechanism. This oscillating mechanism has defects such as low assembly efficiency, and the dead point position of the crank rocker is easily stuck after long-term movement.

[0004] In addition, due to the thin and tall characteristics of the tower fan itself, and the general tower fan adopts the cantilever form with one end fixed, and because the height of the fuselage is obviously greater than the height of the base, it is easy to move the whole machine after moving and during work. The body shakes relative to the base, causing consumers to feel that the product is not stable

Existing shaking head mechanism can't overcome this defective
