Description
Technical field
A kind of plate blade is flapped ground electric fan, belongs to electrical products technical field, particularly relates to a kind of electric fan.
Background technique
Traditional ground electric fan transfers to produce wind in same plane inward turning by blade, and the area of blowing is subject to the restriction of blade diameter, and the scope of blowing is wide, and the cross section of the wind blown is circular, does not meet the needs that human body erects shape.
Summary of the invention
The object of the invention is the above-mentioned deficiency overcoming existing ground electric fan, the cross section of inventing a kind of wind of blowout is rectangle and the wide plate blade of blowing scope is flapped ground electric fan.
A kind of plate blade is flapped ground electric fan, comprises the power line of band plug, controller, motor, main shaft, rocking arm, blade, central synchronous wheel, Timing Belt, leaf synchronizing wheel, bracket and safty shield.Blade is made up of dull and stereotyped and rachis, and rachis upper end is fixed in the middle part of dull and stereotyped lower end with dull and stereotyped, and dull and stereotyped and rachis is in same plane.Motor is fixedly mounted on bracket, and motor output shaft is connected with the lower end of main shaft.Power line with plug is connected with controller, and controller is connected with motor, and controller can control with turning to the rotating speed of motor.Main shaft is vertically arranged on bracket by bearing, and one end of rocking arm is vertical with the upper end of main shaft to be connected, the other end of rocking arm by the bearing stage casing that be connected in rachis vertical with the rachis of blade, rocking arm horizontal arrangement.Blade is vertically arranged, rachis and main axis parallel.Central synchronous wheel is connected with main shaft by being positioned at main shaft stage casing unilateral bearing, and inner ring and the main shaft of interior unilateral bearing are connected, and the outer ring of interior unilateral bearing and central synchronous are taken turns and be connected; Central synchronous wheel is also connected with bracket by outer unilateral bearing, and the inner ring of outer unilateral bearing and central synchronous are taken turns and be connected, and outer ring and the bracket of outer unilateral bearing are connected.Leaf synchronizing wheel and rachis are fixed on the lower end of rachis, and leaf synchronizing wheel is connected by Timing Belt with central synchronous wheel, and central synchronous wheel is 1: 1 with the velocity ratio of leaf synchronizing wheel.Timing Belt plane of movement is vertical with main shaft.Interior unilateral bearing and outer unilateral bearing all adopt the unilateral bearing that can only rotate to a direction.The direction of rotation of interior unilateral bearing and outer unilateral bearing.From the upper end of main shaft toward lower end: when the outer ring of interior unilateral bearing is fixed, its inner ring can only rotate clockwise and can not rotate counterclockwise; When the outer ring of outer unilateral bearing is fixed, its inner ring can only rotate counterclockwise and can not rotate clockwise.Assemble this plate blade flap ground electric fan time, when guaranteeing that rocking arm is in main shaft dead ahead, blade and rocking arm are arranged vertically.Safty shield is fixedly mounted on bracket, and adopt net metal cover, be included by all movable parts of this electric fan, its size is a bit larger tham the sphere of activities of blade.
The flap working principle of ground electric fan of this plate blade is: clapping wind initial position is the dead ahead that rocking arm is in main shaft, now blade is vertical with rocking arm and be positioned at the most front place, plug in, electric machine rotation is controlled by controller, from the upper end of main shaft toward lower end, under the driving of motor, main shaft rotates clockwise, drive rocking arm rotates clockwise, central synchronous wheel maintains static, because the velocity ratio of central synchronous wheel and leaf synchronizing wheel is 1: 1, Timing Belt band movable vane synchronizing wheel rotates counterclockwise, blade is kept to clap wind backward with maximum wind-exposuring area, the spindle speed vanishing when rocking arm goes to main shaft dead astern, now blade is in rearmost position, blade is vertical with rocking arm, complete and clap wind process backward.Reseting procedure is: from blade is in rearmost position, motor reversal is controlled by controller, main shaft rotates counterclockwise under the driving of motor, rocking arm is driven to rotate forward counterclockwise, central synchronous wheel rotates with main shaft with interior unilateral bearing, central synchronous wheel, Timing Belt and leaf synchronizing wheel synchronously rotate counterclockwise around main-shaft axis, the angle of blade and rocking arm keep 90 ° constant.When rocking arm goes to main shaft dead ahead, main shaft stops operating, and now blade has got back to front position, completes reseting procedure, has got back to the initial position of next operation cycle.
Main shaft is driven by motor, controller control motor positive and inverse make main shaft repeatedly rotate 180 ° make rocking arm after before switch 180 ° can realize clapping wind and reseting movement process continuously.Air quantity controls motor speed and blade frequency of flapping by controller and realizes, and blade faster air quantity of flapping is larger.
This contrive equipment is clapped wind process blade and is in maximum wind-exposuring area state all the time, and the angular range that blade is flapped is 180 °, and clap demeanour and enclose comparatively wide, can produce comparatively Wind Volume, efficiency is higher.Blade is vertically arrange, flap in front and back therefore the cross section of the wind produced is rectangle, is applicable to human body and erects shape facility.
