Abstract
Aiming at overcoming the defects of the prior art, the utility model provides an electric fan, the swinging amplitude and swinging speed of which can be adjusted. The electric fan comprises a base, a bracket, a blowing head, a control panel and a main control circuit. The control panel is installed on the bracket; the main control circuit is installed in the control panel; an operating button and an indicator lamp on the control panel are electrically connected with the main control circuit; a motor of the blowing head is electrically connected with the main control circuit; particularly, a servo rotating device is arranged between the bracket and the blowing head; the servo rotating device is fixedly installed on the bracket to drive the blowing head to turn; and an actuating motor is electrically connected with the main control circuit. By adopting the main control circuit to control the servo rotating device, the electric fan can control the swinging amplitude and the swinging speed of the blowing head and can realize user-defined multipoint blowing function to enable the swinging manner of the blowing head of the electric fan to be more suitable for various application occasions so as to reach the effects of being comfortable and convenient and the effects of saving energy and improving efficiency.
Description
Technical field
The utility model relates to a kind of domestic electric fan.
Background technique
The electric fan of Xiao Shouing generally can only be regulated the wind-force size in the market, can only select motionless or with the swing amplitudes of about 150 degree to the control of swing, and fail to control the amplitude size of swing and the speed speed of swing.This just often causes, and wind-force is too concentrated when not swinging, and can not cover the scope that needs blowing, also easily makes us not feeling well; When selecting swing, traditional electrical fan amplitude of fluctuation often reaches 150 degree, and the swing cycle once is often long, and the most of the time blows to the direction that needn't dry, causes waste.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of electric fan that can regulate the amplitude of fluctuation and the swing speed of electric fan is provided.
For achieving the above object, the utility model has been taked following technological scheme:
The fan of blowing scope and yaw adjustable-speed comprises base, support, blowing head, control panel and governor circuit, and described control panel is rack-mount; Described governor circuit is installed in control panel inside; Operating button on the control panel and tutorial light are electrically connected with governor circuit; The motor of blowing head is electrically connected with governor circuit, especially, also is provided with a servo slewing gear between support and blowing head; Described servo slewing gear is fixed on and drives the rotation of blowing head on the support; Described actuating motor is electrically connected with governor circuit.
Described servo slewing gear can be made of actuating motor and retarder.
Below working principle of the present utility model is described:
A series of adjusting button, switch and tutorial light to a blowing working state are set on control panel, the user operates control panel, then governor circuit can be controlled the action of servo slewing gear according to user's operational order, and then makes the blowing head can realize the function of, yaw adjustable-speed adjustable such as the blowing scope, fixed point blowing etc.
Technique effect of the present utility model is: adopt governor circuit that servo slewing gear is controlled, can realize control to a blowing hunting range and swing speed, and the function of self-defined multiple spot blowing, make the swing mode of electric fan blowing head be more suitable for various application, the effect of reach comfortable convenience, economize on resources, raising the efficiency.
