Description

Electric fan

Art

The present invention relates to the household fan enjoyed the cool of relieving summer heat summer, it is a kind of electric fan that simulation people uses a fan.

Background technology

At present, it is commonly used in the domestic electric fan enjoyed the cool of relieving summer heat summer, broadly falls into rotating electric fan, be the flabellum rotation being arranged on axle head by driven by motor, produce the air-flow rotated, relieve summer heat for people and enjoy the cool.But the wind-force of this electric fan is powerful, it is not suitable for weak person and infant uses.

Summary of the invention

The purpose of the present invention, is to invent the electric fan that a kind of people of simulation uses a fan.In summer, the physiological activity of people is vigorous, and ambient temperature is higher, produces substantial amounts of interior-heat in health, need by perspire take out of external.The fine hair hole of human body is opened, and perspiration is constantly discharged, the perspiration of body surface, needs to be dissipated by air-flow, and talent conference feels comfortable nice and cool.Common electric fan, wind-force is powerful, blows for a long time on human body, makes human body produce stress, is automatically switched off the pore of health, and perspiration cannot be discharged, the most powerful wind, is also a kind of ailment said due to cold or exposure, and ailment said due to cold or exposure enters human body by pore, people can be made to fall ill.Observing the hand fan that ancestors hand down, the wind of fan-out is the softest, both perspiration can be taken away, and will not make again ill.Using a fan for a long time, the most tired, people, sleep when, can not use a fan to oneself..

The technical scheme of electric fan of the present invention is: electric fan is by the motor being arranged on chassis, drive No. 1 worm gear reducer, No. 1 worm gear reducer output shaft end installs a cam, and this output shaft end is also connected with No. 2 turbine reduction boxes, output shaft end one swing arm of fixed installation that No. 2 turbine reduction box rotating speeds are lower, swing arm has a swinging axle.The support of one three supporting leg, the upper end of support and casing seat fastening connection are installed on chassis.Rotor sleeve pipe is inserted in casing seat, with casing seat rotation-coupled.Fan seat support connects with the upper end fastening of rotor sleeve pipe, and the lower end of rotor sleeve pipe has one to promote plate, promotes and has vertical hard-wired impeller-hub on plate.Flabellum is inserted in the front end of flabellum seat, fixed connection, flabellum seat and flabellum seat support link joint, and flabellum seat and pulling is actively coupled by winning in succession between set, pulls lower end and the pull lever thread connection of set.The lower end of pull lever passes fixed dam and stage clip and rolling wheel support fixed connection, and roller is arranged on the lower end of rolling wheel support, rotation-coupled.Roller and the cam contact of No. 1 turbine box output shaft end.One end of connecting plate and the promotion plate link joint of the oscillating deck link joint of No. 2 turbine reduction gearbox output shaft ends, the other end of connecting plate and rotor its lower end.Electric fan is owing to have employed said structure, and motor obtains electric, starts to rotate, No. 1 worm gear reducer output slow-speed of revolution, in cam, roller, the effect of stage clip so that pull lever pumps, pulling set also to pump, flabellum seat swings up and down, and drives flabellum to agitate up and down.Meanwhile, the rotating speed that No. 2 worm gear reducer output is lower, at oscillating deck, connecting plate and the effect of promotion plate, rotor sleeve pipe reciprocating rotation.Flabellum is agitated up and down, simultaneously left and right reciprocating rotation, expands wind area.Reach to design requirement.
