Circulation fan

Abstract

The invention discloses a circulation fan, and relates to the technical field of air adjust devices. The circulation fan comprises a base assembly and a machine head assembly; the machine head assembly comprises a front shell, an air outlet device, a first shaft sleeve and a driven gear; the air outlet device comprises fan blades, the fan blades are arranged in the front shell, and the fan bladesare provided with a first rotation center axis; the first shaft sleeve is fixed at the center of the driven gear; the base assembly comprises a rear shell, a rotating motor, a driving gear and a second shaft sleeve, wherein the rotating motor and the second shaft sleeve are both arranged in the rear shell; and the front shell is rotationally arranged at the top of the rear shell, and an included angle a is formed between the installation surfaces of the front shell and the rear shell and the horizontal plane; and the first shaft sleeve is inserted into the second shaft sleeve, the driven gearis meshed with the driving gear, the first shaft sleeve and the second shaft sleeve are provided with a second rotation center axis, and an included angle b is formed between the first rotation centeraxis and the second rotation center axis. The circulation fan has the beneficial effects that three-dimensional large-area air supply can be realized, and the air in the space can be adjusted more quickly.

Description

technical field [0001] The invention relates to the technical field of air conditioning devices, and more specifically, the invention relates to a circulation fan. Background technique [0002] The air conditioning device is an environmental living appliance that regulates the temperature, humidity and cleanliness of the air.
