Description
Technical field
This utility model is related to conditioner, more particularly to orders about the electric fan of air circulation.
Background technology
Prior art air circulation fan, especially desk-top air circulation fan, generally all possess fan head horizontal direction left
The function that right swing and vertical direction swing up and down, to expand blowing range.But it is manual that no matter its head swings mode
Yaw or automatically yaw, the head center of gravity of prior art air circulation fan can shift, and so can both cause air circulation
Fan the shakiness of overall center of gravity, there is the danger toppled over, larger use space can be taken again；In addition, prior art air
This head setting structure of circulation fan can also destroy the overall aesthetics of product in swing process.
Utility model content
The technical problems to be solved in the utility model be avoid the deficiencies in the prior art in place of and propose on a kind of head
Half portion can manually or automatically incline the air circulation fan of yaw, while different angles air-supplies are met, solve prior art
The problem of head centre-of gravity shift in air circulation fan use, elimination can occur product and topple over and take up room big defect, and
Because the twisting of head causes the destruction of product appearance globality and harmony and send when overcoming prior art air circulation fan to work
The little weak point of wind field angle.
This utility model solves the technical problem and can be realized by employing the following technical solutions：
