Electric fan capable of blowing air in large area

Abstract

The invention provides an electric fan capable of blowing air in a large area. The electric fan comprises a base and a motor arranged on the base. The output end of the motor is connected with a drive shaft. The drive shaft is sleeved with a drive gear and a drive bearing in sequence from top to bottom. The drive gear is further provided with at least two driven gears meshed with the drive gear. Fixed shafts are arranged in the centers of the driven gears. Fixed bearings connected with the drive bearing through connecting pieces are arranged on the fixed shafts. Fan blades are arranged at the ends of the fixed shafts and wrapped with a housing which is connected with the base and can disperse air. Power rotation in different directions is achieved through gear meshing, the defect that a traditional swinging electric fan or rotating electric fan can not be used by multiple people is overcome, and the electric fan has the advantages of being firm in connection, convenient to maintain and inspect, high in cooling performance and the like; meanwhile, by the arrangement of rotation speed buttons of different levels, the requirement for use under different conditions can be met, and the electric fan is convenient to use and practical.

Description

technical field [0001] The invention relates to an electrical appliance, in particular to an electric fan capable of blowing air over a large area. Background technique [0002] It is hot in summer, and people usually use electric fans to cool down and avoid the heat. Most of the traditional electric fans are swing-head electric fans. When one person is blowing air, the fan head does not need to swing. However, at present, the fan head can only swing between 90° and 180°, and the area where the wind can be blown is very limited. When there are a lot of people, especially when people sit together and form an approximate circle, it cannot be guaranteed that everyone Can blow to the wind. In order to meet the blowing needs of many people, use two electric fans that can rotate freely on both sides, or use one fan in each direction. However, the number of fans used is large, the power consumption is large, and the cost is high. [0003] The utility model with Chinese applicati...

AI Technical Summary

Problems solved by technology

The rotary electric fan can rotate 360°, and everyone sitting around the rotary electric fan can blow the wind, but there are still the following disadvantages: First, it takes a certain time interval for the rotary electric fan to rotate a circle. That is, the same position needs to wait for the fan to rotate back to the original position before it can blow the wind, so the cooling performance is poor, especially when it cannot be used in high temperature and hot weather; second, the rotary electric fan has no related settings. Speed ​​button, the rotary electric fan only has one level of wind speed, which cannot meet the use in different situations, and the scope of application is limited
