Electric fan

Abstract

The invention discloses an electric fan. The electric fan comprises a base, a supporting rod, a first motor and a second motor; a main controller is embedded in the left side wall of the top of the base; a cavity is formed in the center of the interior of the base; the supporting rod is inserted into the cavity in a penetrating manner; a ferrule is fixed at the top end of a bracket; a mesh enclosure is fixed in the ferrule; an upper fixing seat and a lower fixing seat are installed at the upper end and lower end of the interior of the ferrule correspondingly; the first motor is fixed to the center of the top end of the lower fixing seat; the output end of the first motor is fixedly connected with the bottom end of a positioning frame through a coupler; the second motor is arranged in the positioning frame; and screw rods are installed at the left output end and right output end of the second motor through couplers. According to the electric fan, the assembling efficiency of all components in the electric fan is improved, the height of the electric fan is adjusted, the stable function of the electric fan is ensured, all-directional rotary air supply can be achieved, and the practical effect of the electric fan is enhanced.

Description

technical field [0001] The invention relates to the technical field of electric fans, in particular to an electric fan. Background technique [0002] An electric fan, that is, a fan driven by electric energy, mainly consists of three parts: a motor, fan blades, and a bracket, and is usually used for air circulation and exhaust heat dissipation. In the prior art, there are various types and models of electric fans, and they are widely used in various fields in daily life. [0003] But still there is certain problem in existing electric fan, and concrete problem has following points: [0004] 1. Generally, only the head grille of the electric fan can be disassembled, but for the motor, bracket and other parts, professionals need to use corresponding tools to disassemble. The overall assembly structure is more complicated and the operation is more difficult; [0005] 2. It is difficult to adjust the height of some floor-standing electric fans, and for height-adjustable electr...

AI Technical Summary

Problems solved by technology

[0004] 1. Generally, only the head grille of the electric fan can be disassembled, but for the motor, bracket and other parts, professionals need to use corresponding tools to disassemble. The overall assembly structure is more complicated and the operation is more difficult;

[0005] 2. It is difficult to adjust the height of some floor-standing electric fans, and for height-adjustable electric fans, due to the lack of corresponding limit and friction-reducing structures in the telescopic parts, problems such as lifting overtravel, deflection or stagnation may occur;

[0006] 3. The existing electric fan can only rotate back and forth within a certain range, and its exhaust range is relatively limited, and the practical effect needs to be improved
