Abstract

The invention relates to a structure device of an electric fan which simultaneously blows on the positive and negative directions. The invention is characterized in that the fan vanes 1 and 5 on the positive and negative directions are respectively fixed on the two ends of the motor shaft 2 of a coaxial electromotor 3; a clapboard 6 is fixed on a fixing frame 7; while the fixing frame 7 enters into the outer protective hood 4 of the electromotor as well as is adjusted and fixed by a group of movable bolts. The invention utilizes the same rotating shaft one motor of the electric fan to assemble (a group) two fan vanes which blow positively and negatively to carry out bidirectional blowing to lead the blowing range of the electric fan to be enlarged by one times than that of the electric fan in the existing market, thus achieving remarkable social and economic benefits.

Description

(1) Technical field [0001] The invention relates to a household electric fan, in particular to a structural device for blowing air in both forward and reverse directions of the electric fan. (2) Technical background [0002] At present, electric fans on the market only have the application that each motor drives a fan blade to blow air. Its main disadvantage is that the blowing range is small and the work efficiency is low. In modern society, under the condition of air-conditioning diseases and other emergencies, people expect a lot from electric fans, a natural wind tool. However, current electric fan products can only blow air in a small area, and the wind direction is single, which cannot meet the needs of the market. (3) Contents of the invention [0003] The present invention aims to solve the problem of the small blowing range of the electric fan, and provides an electric fan coaxial motor that can blow air in combination with fan blades in both forward and reverse ...
