Abstract
The utility model relates to an oscillation device for an electric fan, which belongs to the technical field of a home electric production, and the utility model solves the problem that the oscillation action of an electric fan is controlled by an electric button. A miniature speed reducing motor is installed on a rear end cover of an electric fan motor by a support, and the operation of the miniature speed reducing motor is controlled by the electric button. The purpose of electric fan oscillation is achieved through four hinged connecting rods. The utility model has the advantages of simple structure, and convenient and fast operation, the reconstruction of the existing oscillation device for the electric fan can be carried out easily, and conditions are provided to the automation control.
Description
The utility model relates to the head-shaking device of a kind of household appliance technical field, particularly a kind of electric fan.
In the prior art, the action of shaking the head of electric fan, be by being contained in the worm gear shaft of motor back, the drive crank rotation in the four-link mechanism of shaking the head, constantly the push-and-pull connecting rod is realized, it is by strut and tie or knob controlling, and still, all there are following two wretched insufficiency parts in this method, that is: 1. control the strut and tie that electric fan oscillatings move, be located at the rear of fan electromotor, operation inconvenience is even the knob of shaking the head is contained on the panel, exist again because of retaining spring rigidity big, cause operation torsion excessive, so that stay cord often broken, or knob component is damaged .2. easily and can't be realized automation control.
The purpose of this utility model is that a kind of new drive method will be provided, and controls the action of shaking the head, and this can become brisk in operation, and it can effectively solve operation inconvenience simultaneously, and part damages easily and is that automation control creates conditions.
The purpose of this utility model is achieved in that promptly: replace Worm gear mechanism of the prior art with a minitype speed reducing motor, replace strut and tie or knob with button.And the crank in the four-link mechanism of shaking the head just is packed on the shaft of minitype speed reducing motor.Therefore, the action of this mechanism control is just replaced by button.When minitype speed reducing motor was not also switched on, electric fan was not shaken the head.When needs are shaken the head, need only the button of pressing on the lower panel, connect the power supply crank of minitype speed reducing motor and just follow the shaft of minitype speed reducing motor to rotate together, so the connecting rod in the just continuous push-and-pull four-link mechanism of crank makes electric fan oscillating.When pressing the button again, minitype speed reducing motor outage, crank also just stops operating, and shakes the head to stop owing in the design of electric wiring, taked measure, has just accomplished simultaneously that also electric fan under idle situation, can not shake the head by sky.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.
The drawing explanation of accompanying drawing:
Fig. 1 is an installation diagram of the present utility model.
Fig. 2 is electrical control figure of the present utility model.
Embodiment is further described the utility model below in conjunction with accompanying drawing
Among Fig. 1, a support that is screwed (3) is arranged on the rear end cover (2) of fan electromotor (1), it is vertically arranged minitype speed reducing motor (4) that shaft is arranged on the support (3), also is screwed.Crank (5) is connected on the shaft of minitype speed reducing motor (4), and the other end of crank (5) has pin-and-hole, and in order to bearing pin (6) to be installed, connecting rod (7) just is enclosed within on the bearing pin (6).Button in Fig. 2 (9) is contained on the panel, and its is controlled the rotation of minitype speed reducing motor (4) or stops.
When electric fan in the time need not shaking the head work, minitype speed reducing motor (4) is failure to actuate, crank (5) is all relative with connecting rod (7) to be still on the current position, electric fan is not shaken the head.When the needs electric fan oscillating, then press the button (9) on the electric fan panel, make minitype speed reducing motor (4) energising and rotate, crank this moment (5) is driven to rotate, thus by bearing pin (6), push-and-pull connecting rod (7) repeatedly makes shaking the head that electric fan do not stop.Again when electric fan when shaking the head, as long as press the button (9) again, make minitype speed reducing motor (4) outage, just can stop to shake the head.
Electric fan at work, can control the button of shaking the head (9) on demand at any time determines whether shaking the head, but when electric fan during in halted state, then can't make minitype speed reducing motor (4) rotation, just can not shake the head by sky, this can reach by the electrical control figure of Fig. 2, because a lead of minitype speed reducing motor (4) is to be connected together with the switch (8) of fan electromotor (1) by button (9) again.So only when electric fan was worked, the power supply of this minitype speed reducing motor (4) could pass through switch (8), connect the button (9) of minitype speed reducing motor (4) and work.
Claims (1)
- A kind of head-shaking device of electric fan, this device comprises a minitype speed reducing motor (4) and a button (9) that is contained on the electric fan panel, it is characterized in that minitype speed reducing motor (4), be to be vertically mounted on the support (3) of fan electromotor rear end cover (2) back, the shaft of minitype speed reducing motor (4) then with four-link mechanism in crank (5) be connected.
