Abstract

PURPOSE:To make it possible to clean efficiently by arranging a cover in a shape that prevents ultrasonic waves generated coherently from interfering with ultrasonic waves reflected with the cover, even if such a reflection occurs. CONSTITUTION:An ultrasonic vibration element 3 is attached at the widest part 7a of a truncated cone cover 7, with an object to be cleaned arranged facing a liquid jet port 7b of an ultrasonic pump 8. While ultrasonic waves A travels toward the liquid jet port 7b, part B of them passes through the liquid jet port 7b and part C of them is reflected with the cover 7 and then passes through the liquid jet port 7b. Since this prevents reflected ultrasonic waves from interfering with ultrasonic waves traveling in straight lines, cleaning effect is further improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an ultrasonic cleaning device that cleans an object to be cleaned using ejected liquid and ultrasonic waves.

BACKGROUND ART Conventionally, an apparatus shown in FIG. 5 has been proposed as an ultrasonic cleaning apparatus. In FIG. 5, the exponential-shaped cover 1 is hollow.

An ultrasonic vibrator 3 is attached to the wide part 1a at one end of the cover 1, a liquid inlet 4 is provided on the side surface of the cover 1, and a liquid jet port 1 is provided in the narrow part of the cover 1.
An ultrasonic pump 2 is constructed in which an object to be cleaned 5 is disposed opposite to a liquid spout 1b of the ultrasonic pump 2, and an oscillator 6 transmits a predetermined frequency to the ultrasonic vibrator 3. Power is supplied.

In the ultrasonic cleaning device configured in this way, the ultrasonic waves emitted from the ultrasonic vibrator 3 on the cover 1a side are transmitted in parallel to the cover 1a, as shown by arrow A in Fig. 6. cover 1 when it hits the side of
Ultrasonic wave B, a part of the reflected ultrasound wave reflected from the side of
is emitted from the liquid spout 1b, but other ultrasonic waves C are again reflected by the side surface of the cover 1 and directed toward the ultrasonic transducer 3 in the wide portion 1a of the cover 1. Therefore, since the ultrasonic waves C reflected twice or more on the side surface of the cover 1 interfere with the ultrasonic waves generated from the ultrasonic vibrator 3, almost no liquid is ejected from the liquid ejection port 1b, and the cleaning target is efficiently cleaned. There was a drawback that the object 5 could not be washed.

Also, in the truncated conical cover 6 shown in FIG. Some of the ultrasonic waves B are emitted from the liquid spout 6b, but other reflected ultrasonic waves C are reflected again from the side surface of the cover 6.
It heads toward the ultrasonic transducer provided in the wide part 6a of the cover 6.

Therefore, the ultrasonic waves B reflected twice or more on the side surface of the cover 6 interfere with the ultrasonic waves generated from the ultrasonic vibrator, so that almost no liquid is ejected from the liquid ejection port 6b, and the object to be cleaned is efficiently cleaned. The disadvantage was that it could not be washed.

Means for Solving the Problems In order to solve the above problems, the present invention provides an ultrasonic vibrator at one end and a narrow liquid spout at the other end of the cover, so that the liquid can be injected into the side surface of the cover. In an ultrasonic pump provided with an inlet, the ultrasonic waves generated from the ultrasonic vibrator are divided into ultrasonic waves that pass straight through the liquid jet port and ultrasonic waves that are reflected by the cover and pass through the liquid jet port. The cover is configured so that the object to be cleaned is disposed opposite to the liquid spout.

Physiology In the present invention, the ultrasonic wave reflected by the cover is generated by the ultrasonic vibrator by configuring the structure so that the sound wave generated by the ultrasonic vibrator exits from the liquid spout after being reflected straight and once or twice. without interfering with the ultrasonic waves generated.
Since the liquid is efficiently ejected from the liquid ejection port and ultrasonic waves are also emitted from the liquid ejection port, the object to be cleaned can be efficiently cleaned.

Embodiment 1 FIG. 1 shows a configuration diagram of an ultrasonic cleaning apparatus according to an embodiment of the present invention, in which a truncated conical cover 7 is hollow, and a wide part 7a at one end of the truncated conical cover 7 is Ultrasonic transducer 3
is attached, and there is also a liquid inlet 4 on the side of the truncated cone cover 7.
is provided, and a liquid ejection lower b is further provided in the narrow part of the truncated conical cover 7 to constitute an ultrasonic pump 8,
The object to be cleaned 5 is disposed opposite the liquid ejection lower b of the ultrasonic pump 8. In addition, an oscillator 6 is added to the ultrasonic transducer 3.
Power at a predetermined frequency is supplied from

In the ultrasonic cleaning apparatus of this embodiment configured in this way,
As shown in FIG. 2, the ultrasonic vibrator 3 of the ultrasonic pump 8
The ultrasonic waves A generated from the truncated conical cover 7 proceed toward the liquid ejecting lower b, a part B of the ultrasonic waves passing straight through the liquid ejecting lower b of the truncated conical cover 7, and a part C of the ultrasonic waves traveling toward the liquid ejecting lower b of the truncated conical cover 7. A portion of the ultrasonic waves reflected above the cover 7 and passed through the liquid ejection lower b, and further reflected at the lower part of the truncated cone cover 7, is reflected at the upper part of the truncated cone cover 7 and passed through the liquid ejection lower b. do.

In this way, the ultrasonic waves generated from the ultrasonic vibrator 3 are reflected by the truncated cone cover 7 and do not interfere with the generated ultrasonic waves, so the liquid 9 is introduced from the liquid inlet 4 and the liquid ejecting lower The liquid 9 is ejected from the liquid ejecting lower b, and ultrasonic waves are also output.

Therefore, by applying the liquid 9 ejected from the ultrasonic pump 8 and the ultrasonic waves to the object 5 to be cleaned, the object 5 to be cleaned can be cleaned, which has the advantage of increasing the cleaning effect. There is no need to put the object 5 to be cleaned into the cleaning tank, and the liquid hits only the surface of the object 5, so
It has the advantage that drying after washing can be done in a short time.

Fig. 3 shows a configuration diagram of an ultrasonic cleaning apparatus according to another embodiment of the present invention, in which the cover 10 is hollow, and a wide part 10a at one end of the cover 10 has an ultrasonic cleaning device. A sonic vibrator 3 is attached, a liquid inlet 4 is provided on the side surface of the cover 10, and a liquid spout 1 is provided in a narrow part of the cover 10.
0b is provided to constitute an ultrasonic pump 11, and the object to be cleaned 5 is disposed opposite the liquid ejection port tab of this ultrasonic pump 11.

Further, power at a predetermined frequency is supplied from the oscillator 6 to the ultrasonic transducer 3.

In the ultrasonic cleaning apparatus of this embodiment configured as described above, as shown in FIG.
The part B of the ultrasonic wave that goes straight to the narrow part 10b of the cover 10 and the part B of the ultrasonic wave that is reflected once on the inner surface of the cover 10 and is transmitted to the cover 1.
Part C of the ultrasonic wave that gathers at the center of the narrow part 10b of 0
It constitutes the internal form of an exponential form that can be divided into .

In the ultrasonic cleaning device of this embodiment, as in the ultrasonic cleaning device of the above embodiment, the ultrasonic waves generated from the ultrasonic vibrator 3 do not interfere with each other, so the liquid 9 is introduced from the liquid inlet 4. The liquid 9 is ejected from the liquid ejection port 10b, and ultrasonic waves are also output.

Therefore, there is an advantage that the cleaning effect is increased by applying the liquid 9 and ultrasonic waves ejected from the ultrasonic pump 11 to the object 5 to be cleaned, and there is no need to put the object 5 to be cleaned into the cleaning tank. Liquid 9 only on the surface of the object to be cleaned 5
This has the advantage that drying after cleaning can be done in a short time.

In addition, in the cleaning device of the present invention, the ultrasonic pump is configured so that 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 this example, and other shapes of covers may be used.

Effects of the Invention As is clear from the above explanation, in the present invention, even if coherently generated ultrasonic waves are reflected by the cover, the reflected ultrasonic waves do not interfere with each other. At the same time, ultrasonic waves are ejected, and by applying this ejected liquid and the ultrasonic waves to the object to be cleaned, the cleaning effect is greater.Also, there is no need to put the object to be cleaned in the cleaning tank, and the object to be cleaned is Since the liquid hits only the surface of the object, it has the advantage that drying after cleaning can be done in a short time.
