Abstract
The invention discloses an electric fan with the head shaking angle adjustable. The electric fan comprises fan blades, a motor, a control circuit board, a supporting column and a base, wherein an output shaft of the motor is coaxially connected with the fan blades; the base for containing the control circuit board is arranged below the motor; the motor is contained in a shell, and the shell is connected with the upper end of the supporting column through a rotating mechanism; the rotating mechanism comprises a supporting motor and a steering shaft of the fan blades, and the steering shaft is coaxially connected with a steering motor arranged in the supporting column. According to the technical scheme, the designed electric fan has the function that the head shaking angle of the electric fan can be freely adjusted, when the electric fan is used, the head shaking angle of the electric fan can be adjusted according to the number of people sitting in front of the fan, and idle work of the electric fan is avoided.
Description
Technical field
The present invention relates to a kind of electric fan, be specially a kind of electric fan of oscillating angle adjusting.
Background technique
Electric fan is a kind of common household electric appliance, and it increases speed air flow by driven by motor flabellum, makes the sweat of human body surface accelerate evaporation, and brings a burst of slight chill in the air.And in order to allow several individuals in room can fan wind, designed the fan that can shake the head.
The control gear of now widely used electric fan oscillating is by the motor main shaft worm screw of electric fan blade, worm gear drivening rod, makes electric fan according to the several angle motion that oscillates.The panning angle of this mechanical electric fan immobilizes, and sometimes blowing range is limited, and when the panning angle point needing sometimes, but can not satisfy the demands.Therefore, electric fan as a rule, has all done a lot of idle works, and three people are identical with the panning angle that five people enjoy the cool.Both reduce the practical effect of electric fan, caused again waste.
Therefore, designing a kind of electric fan that can regulate panning angle is that relevant field has technical problem to be solved.
Summary of the invention
The object of the invention is the electric fan for a kind of oscillating angle adjusting is provided, to solve the problems referred to above of prior art.
Object of the present invention can be achieved through the following technical solutions:
An electric fan for oscillating angle adjusting, comprises fan blade, motor, control circuit board, supporting post and base, and the output shaft of described motor is coaxially connected with fan blade; Motor below is for containing the base of control circuit board; Described motor is contained within housing, and housing is connected with the upper end of supporting post by a rotating mechanism; Described rotating mechanism comprises the steering shaft of a support motor and fan blade, and the steer motor that steering shaft and is arranged in supporting post is coaxially connected.
Described fan blade is provided with netted cover body outward, and to prevent careless manipulation, human body is encountered fan blade and caused damage.
Described supporting post is made up of upper and lower two-part: upper support column and lower support post, be connected by the joint of mutual interlock between upper support column and lower support post, and fix by screw.To facilitate the elevation angle that regulates fan blade.
Described steer motor rotating speed is fixed, and regulates by the time of steer motor positive and reverse steering is set the angle turning in fan blade horizontal plane.
On described base, be designed with control knob, control the corner of fan blade and the rotating speed gear of motor.
The present invention has omitted circuit connecting mode, power supply and the fastening piece of easy realization.
The electric fan designing by technical solution of the present invention, has the function of the angle of regulating electric fan swinging arbitrarily, when use, can carry out according to the number before electric fan the angle of regulating electric fan swinging, has avoided electric fan to flog a dead horse.

In figure: 1, motor 2, fan blade 3, housing 4, upper support column 5, lower support post 6, base 7, steering shaft 8, steer motor.
Embodiment
Set forth technical characterstic of the present invention below in conjunction with the nearly step of the drawings and specific embodiments.
The electric fan of a kind of oscillating angle adjusting as shown in Figure 1, comprises fan blade 2, motor 1, control circuit board, supporting post and base 6, and the output shaft of described motor 1 is coaxially connected with fan blade 2; Motor 1 below is the base 6 that contains control circuit board; Described motor 1 is contained within housing 3, and housing 3 is connected with the upper end of supporting post by a rotating mechanism; Described rotating mechanism comprises the steering shaft 7 of a support motor 1 and fan blade 2, and the steer motor 8 that steering shaft 7 and is arranged in supporting post is coaxially connected.
Described fan blade 2 is outer is provided with netted cover body, and to prevent careless manipulation, human body is encountered fan blade 2 and caused damage.
Described supporting post is made up of upper and lower two-part: upper support column 4 and lower support post 5, be connected by the joint of mutual interlock between upper support column 4 and lower support post 5, and fix by screw.To facilitate the elevation angle that regulates fan blade 2.
Described steer motor 8 rotating speeds are fixed, and regulate by the time of steer motor 8 positive and reverse steerings is set the angle turning in fan blade 2 horizontal planes.
On described base 6, be designed with control knob, control the corner of fan blade 2 and the rotating speed gear of motor 1.
The present invention has omitted circuit connecting mode, power supply and the fastening piece of easy realization.
