Abstract

The invention provides an electric fan head assembly and an electric fan. The electric fan head assembly comprises fan blades, a shaft sleeve, a rotary knob, an insert and a motor. A mounting hole isformed in the center of the fan blades. The shaft sleeve is fixedly mounted in the mounting hole. A first anti-eccentric part is arranged on the inner wall face of a shaft hole of the shaft sleeve. The rotary knob is detachably mounted at the top of the shaft sleeve. The insert is fixedly mounted on an output shaft of the motor, arranged in the shaft hole in a penetrating mode and fixedly connected with the rotary knob. A second anti-eccentric part matched with the first anti-eccentric part is arranged on the insert. Assembly eccentricity can be prevented from occurring between the shaft sleeve and the insert, the unbalanced weight of the electric fan head assembly is decreased, thus shaking of the fan blades and the electric fan head assembly is reduced, and the operating stability of theelectric fan head assembly is improved.

Description

technical field [0001] The present invention relates to the technical field of fans, and in particular, to an electric fan head assembly and an electric fan. Background technique [0002] At present, in the electric fan products at home and abroad, the fan head swings left and right and shakes up and down, which seriously affects the running stability. In the category of fans, common floor fans, DC floor fans, platform fans, and square fans have experienced this resonance problem in different models. At present, most products adopt the method of not setting gears in the vibration range, but it seriously affects the uniformity of the speed span between gears and affects the user experience. [0003] At present, in the assembly structure of the fan blade and the motor shaft, in order to facilitate the user to install and disassemble the fan blade, the matching gap is large, which will inevitably lead to the problem of assembly eccentricity, resulting in an increase in unbalan...
