Description
Technical field
A kind of blowing causes the household appliances of cool usefulness.
Background technique
Existing electric fan blowing mode has two kinds: a kind of is the electric fan of not shaking the head, and only toward a direction blowing, its defective is to be not suitable for two people or many people use; Another kind is the electric fan of shaking the head, and can sweep wind repeatedly in the hexagonal angle degree scope of setting, and its defective is that single user has long gap period to blow less than wind no cooling feeling.That is to say, to unmanned place, flog a dead horse, wasted the energy in the wind of gap period.
Summary of the invention
The purpose of this utility model provides a kind of electric fan of adjustable panning angle, accomplish to sweep demeanour enclose adjustable, energy saving.
The utility model comprises that front-end of spindle is equipped with the motor of blade, the motor case front end is hinged on the stub axle of support column top, electric machine main shaft rear end worm screw drives worm gear, small gear on the worm gear central shaft drives gearwheel, the gearwheel central shaft is set in the support that connects firmly with motor housing, improvements are that the central shaft lower end has adjustment seat, regualting frame is fixed on the adjustment seat with screw, bar-shaped trough is arranged on the regualting frame, tooth bar is arranged in the bar-shaped trough, and the upper end has the adjustable lever of snap ring to intert in bar-shaped trough, pinion rack on the adjustable lever and tooth bar engagement, transmission arm one end is hinged on the secondary bearing pin in support column top, and the other end is hinged on the adjustable lever.The inner of bar-shaped trough is over against central shaft, when adjustable lever is positioned at bar-shaped trough when inner, the central lines of adjustable lever and central shaft.
Using method and working principle are as follows:
In the time of the rotation of driven by motor blade, the rear-end of spindle worm screw is by the rotation of worm gear drives gearwheel, at this moment if adjustable lever is transferred to the bar-shaped trough inner end positions, the central lines of adjustable lever and central shaft, no moment of torsion, will to drive adjustment seat and regualting frame be the center rotation with the adjustable lever to gearwheel so, do not have external force to act on motor, be that motor maintains static, fan blade is only toward a direction blowing.
If rotation adjustable lever, make adjustable lever move a segment distance outward from bar-shaped trough the inner, be adjustable lever center line and gearwheel central shaft center line when one segment distance is arranged, the active force desire that produces of gearwheel rotation forces adjustable lever to center on the rotation of gearwheel central shaft by adjustment seat and regualting frame so.Be hinged on transmission arm on because of adjustable lever this moment, constant and the other end of the length of transmission arm is hinged on the support column, the support column will produce an identical reaction force of size and act on the adjustable lever through transmission arm, make the relative gearwheel central shaft of adjustable lever form a reaction torque power.Reaction torque power forces electric machine main shaft to be swung in the several angle scope through the transmission of regualting frame, gearwheel, worm gear, promptly sweeps wind in the several angle scope.This angular range reaches when adjustable lever is positioned at the bar-shaped trough outermost end and sweeps wind angle maximum along with adjustable lever increases from the increase of the inner distance of bar-shaped trough.
Compared with the prior art, the utility model characteristics are to enhance product performance, and can adjust panning angle on demand, promptly in 0～120 ° of scope, realize the panning angle step-less adjustment, avoid unnecessary wide-angle to shake the head and sweep wind, reduce the time of making idle work, save wind energy and raising and cause cool effect.
Another technological scheme of the present utility model is that tooth bar directly is fixed on the adjustment seat with installation sheet and screw, with "
" type groove card makes pinion on the adjustable lever on tooth bar, all the other technical characteristicss are identical with technological scheme noted earlier with working principle, and this place repeats no more.
