Description
Technical field
The utility model relates to a kind of oscillation adjuster, especially a kind of electric fan oscillation adjuster.
Background technique
Electric fan is called for short electric fan, is a kind of motoring flabellum rotation that utilizes, and reaches the household electric appliance that make air quicken circulation, is mainly used in cooling and heatstroke-eliminating and ventilating air.Be widely used in family, office, shop, hospital and hotels and other places.
General domestic electric fan: ceiling fan, desk fan, stand fan, wall fan etc. are arranged.The branch of shaking the head He do not shake the head is arranged again in desk fan and the stand fan.
When the people is many, generally all be to use stand fan, because the wind-force of stand fan is stronger, can also vacillate now to the left, now to the right, all sent to nice and cool wind for the people of different azimuth.Yet at the weather comparative heat, when the people was less again, fan did not swing, and the somebody will experience less than wind, allow fan swing, because amplitude of fluctuation is bigger again, limited wind-force can not get better utilization.
The model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of electric fan oscillation adjuster, and it adopts the gear sliding type, and the amplitude that electric fan swings is set to: 30 degree, 60 degree or 120 degree.
In order to realize that the technological scheme that the purpose of this utility model adopts is: a kind of electric fan oscillation adjuster is characterized in that: it by control switch, casing, transmission shaft, driving crank, rotating disc, spring, groove, cog, transmission worm screw, middle gear, lower gear, pearl constitute; Described control switch is the cylinder indentation, 2/5ths places, top are provided with circular hole, the size of circular hole is bigger slightly than the diameter of spring, spring passes this circular hole, both ends of the spring is corresponding with the groove in the circular hole of casing top by pearl, control switch lower end 5/5ths, 4/5ths and 3/5ths places are provided with lower gear, middle gear respectively and cog, three gears can both with the interlock of transmission worm screw.
Described transmission worm screw is cylindrical, an end and gear interlock mutually, and the other end is installed in the support; Described driving crank upper end connects the bottom that transmission shaft is installed in casing, and the lower end connects rotating disc and is installed on the supporting base by connecting rod; Described chassis is an arch-shaped, and arch face is provided with control panel, and supporting base is installed in the center of chassis arch face; Described support is cylindrical, and inside is provided with the control motor, and front end is by the rotation of bearing control fan head.
The beneficial effects of the utility model are: can either be when the people is many, significantly vacillate now to the left, now to the right, again can be when the people be few, be adjusted into vacillating now to the left, now to the right by a small margin, effectively utilized the wind-force that electric fan brought, easy to operate, practical, be applicable to various mini-sessions, various office space and vast places such as family.
