Abstract
The utility model discloses an electric fan with full wind direction, wherein an swivel bearing is fixed on a foundation of the electric fan, and a support arm is installed on the swivel bearing; power supply line of the fan head passes through the center of the support arm, and then is connected with the external power supply by slip-ring type connection mode in the foundation, for avoiding the power supply line binding; a small fan is installed on the position of the fan head biasing a rotating shaft center of the support arm, for providing rotating torque for the fan head. The electric fan with full wind direction of the utility model can be placed at center of a space for providing wind around, and implements 360 degree rotating of the fan head.
Description
Technical field
The utility model relates to electric fan, especially seat fan or desk fan.
Background technique
No matter present electric fan seat formula or desk-top, wind direction be all towards a direction, the function although band is shaken the head, maximum can only be waved in 120 ° angle, can not full blast to i.e. 360 ° rotation.
The model utility content
The utility model provides a kind of electric fan with full wind direction of 360 ° of rotations, for reaching the purpose of 360 ° of rotations.The technical solution of the utility model is, it comprises the base of electric fan, and support arm and fan head is characterized in that:
1, the base of electric fan is provided with swivel bearing, and support arm is installed on the swivel bearing free to rotate;
2, the power line of fan head passes in the heart from support arm, passes the back and is connected with extraneous power supply by the sliding ring type Placement in base, and power line is not twined;
3, at the position of departing from the support arm axis of rotation of fan head small fan is installed, for the rotation of fan head provides moment.
Electric fan with full wind direction of the present utility model can be placed in the middle of certain space to around the crowd pectinid is provided, realized the purpose of fan 360 ° of rotations.
