Description

AN ULTRASONIC GENERATOR

The present invention relates to an ultrasonic generator.

An ultrasonic generator is an electroacoustic transducer for generating acoustic waves of 20 kHz or more. Generally, in order to generate ultrasonic waves, a high frequency power source is used as a base to convert a magnetic field to mechanical vibration or a voltage variation to mechanical vibration Electrical vibrations must be converted into mechanical vibrations.

That is, according to Patent Document 1, the ultrasonic generator includes a piezoelectric unit for converting pressure into electric energy, an ultrasonic wave generator for generating ultrasonic waves using electric energy generated from the piezoelectric unit, and an ultrasonic wave focusing unit for connecting and generating ultrasonic waves generated And it does not require a separate power supply.

Patent Document 2 discloses a portable ultrasonic generator. The ultrasonic generator includes a controller for controlling high-pressure generation, frequency control, and display operations required to generate ultrasonic waves, an ultrasonic electric signal generator, The ultrasound transducer and the focusing device for switching can be miniaturized and carried, thereby enabling the ultrasound waves to be concentratedly applied to a local spot.

On the other hand, typical application decomposition of ultrasonic wave is divided into communication application and power application. Fish detectors, nondestructive inspection, ultrasonic diagnosis are examples of electrons, and ultrasonic processing and ultrasonic cleaning are the latter examples.

The specificity and features of the present invention will become more apparent from the following detailed description and examples, which are to be taken in conjunction with the accompanying drawings. It should be noted that, in the present specification, the reference numerals are added to the constituent elements of the drawings, and the same constituent elements are assigned the same number as much as possible even if they are displayed on different drawings. Also, terms such as "first", "second", "one side", "another side" and the like are used to distinguish one element from another element, and the element is not limited thereto . In the following description of the present invention, a detailed description of related arts which may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the ultrasonic generator 1 according to the embodiment of the present invention can be used as a gas or liquid, more specifically, by a pressure of a fluid including compressed air, water, or cutting oil Ultrasonic waves are generated by using the ultrasonic transducer 20 made of a resonant metal. The ultrasonic wave generated at this time is about 10 to 100 kHz at a pressure of about 2 to 10 bar.

The ultrasonic generator 1 includes a hollow body having an ultrasonic oscillator 20 therein and an ultrasonic vibrator 20 connected to the inlet 11 and the outlet 12 of the body 10, And a hollow adapter 30 for fixing the ultrasonic generator 1 to the outside and connecting the ultrasonic generator 1 to the outside.

The body 10 has an inlet 11 through which a fluid flows into the left side of the figure and an outlet 12 through which a fluid is discharged to the right side. The body 10 is formed into a cylindrical shape having a hollow shape. The threaded portion and the valley are continuously formed from the inlet 11 to the outlet 12 so that the fixing portion 31 of the adapter 30 can be screwed easily. The body 10 may be a method of processing a metal, or may be a method of molding using a metal mold.

The adapter 30 is a hollow configuration which is respectively fastened to an inlet 11 and an outlet 12 of the body 10 and two adapters 30 are provided per one body 10. The adapter 30 is integrally formed with the fixing portion 31 and the fixing portion 31 which are inserted into the inlet 11 and the outlet 12 of the body 10 and is in close contact with the end of the body 10, And a flange that performs a function of a stopper.

Therefore, the adapter 30 is assembled by inserting the fixing portion 31 until the flange 32 is brought into close contact with the end of the body 10, The ultrasonic transducer 20 is fixed to the inside of the body 10 by supporting the one surface and the other surface of the ultrasonic transducer 20. [

The adapter 30 includes an external connection portion 33 integrally formed with the flange 32 and basically including the fixing portion 31 and the flange 32 and protruding from the opposite side of the fixing portion 31 . The external connection part 33 is used to connect the ultrasonic generator 1 to the outside, thereby making it possible to more easily connect the ultrasonic generator 1 to a pipe or the like.

Here, the external connection portion 33 and the fixing portion 31 may be connected to the body 10 through a general insertion method and a screw fastening method, respectively. In the case of the screw fastening method, However, it is preferable that the ultrasonic generator 1 can effectively prevent separation due to an external impact applied to the ultrasonic generator 1.

The ultrasonic transducer 20 has a structure in which an oil passage 21 is formed in an elliptical shape at a central portion so that the fluid introduced into the inlet 11 of the body 10 can pass through the adapter 30 as an intermediate body, And is fixed to the center of the body 10 through a fixing part 31 provided inside the body 10.

The ultrasonic transducer 20 is formed in a disc shape having a size corresponding to the inner diameter of the body 10 using a metal material and has a channel 21 that can be interpreted as an elliptical or rugby ball shape having a narrower width from the center to the edge, The ultrasonic vibrator 20 resonates with the pressure of the flow of the fluid as if the vocal cords are ringing when the fluid flowing into the inlet of the body 10 passes through the flow path 21 to generate ultrasonic waves .

As shown in FIG. 4, the ultrasonic generator 1 according to the embodiment of the present invention is applied to the filter 100 for removing sludge from cutting oil.

More specifically, the ultrasonic generator 1 is installed in an air injection pipe 110 of a filter 100, which is supplied with compressed air from an air compressor through an adapter 30 screwed to both ends of the body 10 The ultrasonic vibrator 20 generates ultrasonic waves by the pressure of the compressed air flowing into the air injection pipe 110 to remove the sludge adhering to the filter 120 in the process of filtering the cutting oil.

That is, the vibration of the ultrasonic generator 1 is transmitted to the cutting oil, and the sludge attached to the filter 120 is removed by a cavitation effect by ultrasonic waves. It should be noted, however, that the ultrasonic generator 1 according to the embodiment of the present invention can be installed and operated in a tooth cleaner or a nondestructive inspection device for cleaning teeth.

Although the present invention has been described in detail with reference to the embodiments thereof, it is to be understood that the ultrasonic generator according to the present invention is not limited to the ultrasonic generator according to the present invention, It is obvious that the present invention can be modified or improved by those skilled in the art.

The scope of the present invention is defined by the appended claims, and all changes and modifications that come within the meaning and range of equivalency of the claims are therefore intended to be embraced by the appended claims.
