Convenient-to-assemble circulation fan capable of rotating up and down left and right

Abstract

The invention relates to a convenient-to-assemble circulation fan capable of rotating up and down left and right. The convenient-to-assemble circulation fan comprises a fan assembly, a seat assembly,a supporting assembly and a rotating seat, wherein the rotating seat is provided with a rotating shaft, a limiting convex part and a mounting lug part; the supporting assembly is provided with a pivoting hole and a limiting hole, the rotating shaft is adapted to the pivoting hole, and the limiting convex part is adapted in the limiting hole; and the seat assembly comprises a seat body, a main control circuit board, a power panel, a base plate upper cover and a rotating unit, wherein the rotating unit comprises a rotating motor, a crank and a rotating connecting rod, wherein the rotating shaftof the rotating motor is connected with the crank, the crank is connected with the rotating connecting rod, the rotating connecting rod is connected with the base plate upper cover, and the main control circuit board is electrically connected with the power panel and the rotating motor correspondingly. The convenient-to-assemble circulation fan can swing up and down left and right, and has an omni-directional direction turning function, the range of an air swing is larger, and an application range is wider; meanwhile, the fan assembly can be adjusted to a proper gear position (or angle) in a vertical direction according to use requirements; and meanwhile, the gear is convenient to switch and is easy to shift, and noise cannot be generated.

Description

technical field [0001] The invention relates to the field of a circulation fan, in particular to an easy-to-assemble circulation fan that can rotate up, down, left, and right. Background technique [0002] The main function of the circulation fan is to form a convective circulation of the indoor air, and achieve the effect of balancing the temperature with a reasonable air flow direction. Generally, it cannot be directly used as a refrigerator. It is often used in conjunction with an air conditioner to achieve rapid cooling and balance the room temperature. It can also be used to circulate indoor and outdoor air, allowing indoor and outdoor air to alternate. [0003] The existing circulation fan is inconvenient to assemble, the positioning effect is poor and unstable, and the reliability and stability of the circulation fan cannot be guaranteed during operation, resulting in a short service life of the circulation fan; at the same time, the swing angle of the general circul...
