Description

Description: TECHNICAL FIELD The present invention relates to an ultrasonic cleaning device for cleaning an object to be cleaned by ultrasonic waves focused on the ejected liquid and outside the liquid ejection port of a cover. .

[Prior Art] Conventionally, an apparatus shown in FIG. 5 has been proposed as an ultrasonic pump apparatus. In FIG. 5, an exponentially shaped cover 1 is hollow, an ultrasonic transducer 3 is attached to a wide portion of one end of this cover, and a liquid inlet 4 is provided on a side surface of the cover 1. , Cover 1
The ultrasonic pump 2 is provided with the liquid jet port 1b in the narrow part of the ultrasonic pump 2. The object to be cleaned 5 is arranged so as to face the liquid jet port 1b of the ultrasonic pump 2. Electric power of a predetermined frequency is supplied to the sound wave oscillator 3.

[Problems to be Solved by the Invention] In the ultrasonic pump device configured as described above, the ultrasonic waves emitted from the ultrasonic transducer 3 on the cover 1a side are parallel to each other as shown by an arrow A in FIG. When it hits the side surface of the cover 1, a part of the reflected ultrasonic wave B is emitted from the liquid ejection port 1b, but the other ultrasonic wave C is reflected again by the side surface of the cover 1. By doing so, it goes toward the ultrasonic transducer 3 of the wide portion 1a of the cover 1. Therefore,
The ultrasonic waves C reflected twice or more on the side surface of the cover interfere with the ultrasonic waves generated from the ultrasonic vibrator 3, so the liquid is ejected by the pressure of the ultrasonic waves, but the ultrasonic waves are ejected from the liquid ejection port 1b. There is a drawback that the object to be cleaned 5 cannot be efficiently cleaned because it is hardly ejected.

Also, in the truncated cone cover 6 shown in FIG. 7,
The ultrasonic wave A generated from the ultrasonic transducer mounted on the wide portion 6a of the cover 6 is reflected by the side surface of the cover 6, and a part of the reflected ultrasonic wave B is emitted from the liquid ejection port 6b, but is reflected. The other ultrasonic waves C thus reflected are reflected again by the side surface of the cover 6 and travel toward the ultrasonic transducer provided in the wide portion 6a of the cover 6.

Therefore, the ultrasonic wave B reflected twice or more by the side surface of the cover 6 interferes with the ultrasonic wave generated from the ultrasonic transducer, and the liquid is ejected from the liquid ejection port 6 by the pressure of the ultrasonic wave. Sound waves are hardly ejected from the liquid ejection port 6b,
There is a drawback in that the object to be cleaned cannot be efficiently cleaned.

[Means for Solving the Problems] In order to solve the above problems, the present invention has an ultrasonic vibrator attached to one end and a liquid ejection port smaller than the diameter of the ultrasonic vibrator formed at the other end. Then, a liquid introduction port is provided on the side surface, and the ultrasonic wave generated from the ultrasonic transducer and passing straight through the liquid ejection port and the ultrasonic wave reflected on the inner surface and passing through the liquid ejection port are the liquid. A cover is configured so as to focus on the outside of the ejection port, a cleaning liquid is supplied from the liquid introduction port to the inside of the cover by a liquid supply means, and a portion where the ultrasonic waves are focused is provided facing the liquid ejection port. It is characterized in that a cleaning product is provided.

[Operation] In the present invention, the ultrasonic wave generated by the ultrasonic transducer is straight from the liquid ejection port and the ultrasonic wave generated from the liquid ejection port by one or two reflections is outside the liquid ejection port of the cover. Since the ultrasonic waves reflected by the cover do not interfere with the ultrasonic waves generated by the ultrasonic transducer by being configured to focus, the ultrasonic waves are efficiently emitted from the liquid ejection port, so that they are supplied to the cover. The object to be cleaned can be efficiently cleaned together with the liquid.

[Embodiment 1] FIG. 1 is a diagram showing the configuration of an ultrasonic cleaning apparatus according to an embodiment of the present invention, in which the truncated cone cover 7 is hollow and one end of the truncated cone cover 7 has a wide width. Ultrasonic transducer 3 on 7a
Is attached to the side of the truncated cone cover 7 and the liquid introduction port 4
Is attached, and further, a liquid ejection port 7b is formed in a narrow portion of the truncated cone cover 7 to configure an ultrasonic cleaning device 8,
The object to be cleaned 5 is arranged so as to face the liquid ejection port 7b of the ultrasonic cleaning device 8. In addition, the oscillator 6 is added to the ultrasonic transducer 3.
From the liquid inlet 4, a liquid such as a cleaning liquid is supplied by a pump or the like provided outside.

Then, as shown in FIG. 2, the ultrasonic wave A generated from the ultrasonic transducer 3 of the ultrasonic cleaning device 8 advances toward the liquid ejection port 7b, and a part B of the ultrasonic wave goes straight to the truncated cone. The ultrasonic waves that have passed through the liquid ejection port 7b of the cover 7 and have been partially reflected by the ultrasonic waves above the truncated cone cover 7 have passed through the liquid ejection port 7b, and have also been reflected at the lower portion of the truncated cone cover 7. Part D of the liquid is reflected at the upper part of the truncated cone cover 7
The ultrasonic waves that pass through 7b and pass through these liquid ejection ports 7b are focused outside the liquid ejection port 7b.

In this way, the ultrasonic wave generated from the ultrasonic transducer 3 does not interfere with the ultrasonic wave that passes straight through the ejection port 7b of the cone cover 7 and the ultrasonic wave reflected on the inner surface of the truncated cone cover 7, By introducing the liquid 9 from the introduction port 4 by another pump, the liquid 9 is ejected from the liquid ejection port 7b and ultrasonic waves are ejected.

Therefore, the object 5 to be cleaned can be cleaned by applying the liquid 9 and ultrasonic waves ejected from the ultrasonic cleaning device 8 to the object 5 to be cleaned, which is advantageous in that the cleaning effect is further enhanced. Moreover, since it is not necessary to put the article to be cleaned 5 in the cleaning tank, and the liquid only hits the surface of the article to be cleaned 5, there is an advantage that drying after cleaning can be performed in a short time.

[Embodiment 2] FIG. 3 is a view showing the configuration of an ultrasonic cleaning apparatus according to another embodiment of the present invention, in which the cover 10 is hollow, and one end of the cover 10 has a wide portion 10a. The ultrasonic transducer 3 is attached, and the liquid inlet 4 is provided on the side surface of the cover 10.
Further, a liquid ejection port 10b is provided in a narrow portion of the cover 10 to configure an ultrasonic cleaning device 11, and an object to be cleaned 5 is disposed facing the liquid ejection port 10b of the ultrasonic cleaning device 11. There is. In addition, electric power of a predetermined frequency is supplied from the oscillator 6 to the ultrasonic transducer 3.

In the ultrasonic cleaning apparatus of the present embodiment configured as described above, as shown in FIG.
Ultrasonic wave A generated from the ultrasonic transducer attached to 10a
Is a part B of the ultrasonic wave which goes straight to the narrow part 10b of the cover 101 and a part C of the ultrasonic wave which is reflected once on the inner surface of the cover 10 and gathers at the center of the narrow part 10b of the cover 10. The inner form of the exponential type is divided. Also in the ultrasonic cleaning apparatus of the present embodiment, since the ultrasonic waves generated from the ultrasonic transducers 3 do not interfere with each other as in the ultrasonic cleaning apparatus of the above-described embodiments, the liquid introduction port 4
When the liquid 9 is introduced from above by the liquid supply means, the liquid ejection port 10
Liquid 9 and ultrasonic waves are output from b.

Therefore, the liquid 9 ejected from the ultrasonic cleaning device 11
By applying ultrasonic waves to the object 5 to be cleaned, there is an advantage that the cleaning effect is further increased, and since it is not necessary to put the object 5 to be cleaned in the cleaning tank, the liquid 9 hits only the surface of the object 5 to be cleaned. The advantage is that drying after washing can be done in a short time.

In the cleaning apparatus of the present invention, if the ultrasonic pump is configured so that the coherently generated ultrasonic waves are reflected on the inner surface of the cover and the reflected ultrasonic waves do not interfere with each other, The cover is not limited to the example, and a cover having another shape may be used.

[Effects of the Invention] As is clear from the above description, according to the present invention, even if ultrasonic waves coherently generated are reflected by the cover, the cover is formed in such a shape that the reflected ultrasonic waves do not interfere with each other. , The ultrasonic waves are spouted together with the liquid supplied to the cover, and by applying the spouted liquid and ultrasonic waves to the object to be cleaned, there is an advantage that the cleaning effect is further increased. Since there is no need to put it in and the liquid hits only the surface of the object to be cleaned, there is an advantage that drying after cleaning can be done in a short time.
