Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a vibrator used in a small electric appliance.

Vibrators using AC electromagnets have a simple structure, are small, inexpensive, and do not cause radio wave interference, and have been used to power massagers and small electric appliances.

However, apart from massagers that use the vibration itself, the reaction vibration is transmitted to the hand holding the device, the table that comes into contact with it, and generates unpleasant vibrations and noise, so it is not suitable for a wide range of power for general devices. The reality is that it is not being used effectively.

The present invention provides a rotating vibration part of an AC rotating vibrator with two axes,
It has two oscillators and is directly connected with a built-in balancer to prevent reaction vibration and to produce tabi-vibrator power.

EMBODIMENT OF THE INVENTION Hereinafter, as one embodiment of the present invention, a biaxial rotary pipe rake as a power source for electric scissors will be explained in detail with reference to the accompanying drawings.

On the magnetic pole side of an electromagnet consisting of an E-type iron core 1 and an excitation coil 14, a rotating shaft 2.3 is mounted on the side plate 15.20 vertically with the center line in between.
It is fixed together with the iron core 1.

A vibrator 6.7 made of strong plastic (for example, nylon) is attached to each of the rotating shafts 2.3.

Each vibrator is integrally molded with an iron piece 4.5 that forms a magnetic circuit with the E-type iron core 1 during suction, and is rotatably arranged to maintain a small gap with the magnetic pole of the E-type iron core 1. ing.

As shown in FIG. 2, both vibrators 6.7 are assembled by means of their gears so as to rotate in opposite directions.

A fixed shaft 16 is attached to the left tip of the side plate 15.20, and the upper blade holder 8 of the electric scissors, which is the purpose movement body of the instrument, is mounted on this shaft, and the right rear end thereof is fitted into the gear part of the vibrator 6. It is made in the shape of a matching gear.

Due to this fitting, the motions of the vibrators 6 and 7 are combined and transmitted to the upper cutter stand 8.

When an alternating current is passed through the excitation coil 14, the magnetic attraction force of the E-type iron core 1 to the iron piece 4.5 changes based on the frequency of the alternating current.

At this time, the iron piece 4.5 attached to the vibrator 6.7 is designed to exert an attractive force in the direction in which 4 rotates clockwise and 5 rotates counterclockwise.

In addition, resonance springs 9 and 10 are attached to the upper blade stand 8 from above and below.
The other end is fixed with spring retainers 11 and 12 and pressurized toward the center.

By appropriately selecting the strength of the magnet and resonance spring in the above structure, the vibrator 6, T, and the upper cutter stand 8 connected thereto can be rotated and vibrated within a certain range by a multiple of the AC frequency. can.

The principle is the same as that of a conventional AC vibrator, so a description thereof will be omitted.

Note that switches, wiring, the outer case of the appliance, etc. are omitted from the drawing.

An upper blade 17 is attached to the tip of the upper blade stand 8, and a lower blade 19 is attached to a fixed lower blade stand 18, which is indicated by a broken line.

The small range of reciprocating rotational vibration of the upper blade stand 8 causes the upper blade 17 to vibrate up and down.

On the other hand, the upper blade rest 8 is constantly pressed in the direction of the lower blade 19 by the pressure spring 21 and moves up and down, so that the upper blade 17 and the lower blade 1
It is possible to cut paper, cloth, etc. placed between 9.

A balance weight 13 of an appropriate weight is attached to the opposite side of the iron core 5 of the lower vibrator I to cancel out or minimize the recoil caused by the vibration of the upper cutter stand 8 and the resonance spring 9 and 10 that move in the opposite direction. I'm letting you do it.

Both vibrators 6.7 and iron piece 4.5 rotate in opposite directions, so
It is possible to generate power without producing any reaction.

Although the resonance spring 9.10 is provided 7 on the upper blade stand 8 in the embodiment, it can also be provided at an appropriate position on the vibrator 6.7.

Furthermore, the type and shape of the spring can be freely selected.

Although the iron piece 4.5 is integrally molded with the vibrator 6.7, it may be fixed with screws, rivets, or the like.

Furthermore, if necessary, it is also possible to directly utilize the reciprocating rotational motion of the vibrators 6.7 as power.

By implementing the present invention, in addition to taking advantage of the characteristics of AC pipe rake, which are small, simple, and inexpensive, various electric cutters can be used as highly practical power with almost no reaction vibration.
It can be widely used in small air pumps, etc.
