Description

[Detailed Description of the Invention] The present invention relates to an ultrasonic vibration device suitable for use in ultrasonic cleaning.

As shown in FIG. 1, this kind of ultrasonic vibrator for cleaning uses ultrasonic waves from all around the radiating surface of an ultrasonic vibrator 1 such as a Langevin type vibrator through a vibration transmission rod 2 extending coaxially. A device in which a vibration radiator 3 of a three-dimensional shape capable of emitting sound waves, for example a short cylinder, is coupled is known, and when such a vibration device is attached to the cleaning tank 4, the ultrasonic vibrator 1 is placed above the cleaning tank 4. A flange 2 provided on the main part of the vibration transmission rod 2 so as to immerse the vibration radiator 3 in the cleaning liquid 5 in the cleaning tank.
Attach the vibrator to a fixing device (not shown) by holding it with a, but be careful when filling, replenishing, or replacing the cleaning fluid, as there is a risk that some of the cleaning fluid may get onto the vibrator and harm the electrical performance. There was a problem that it was necessary.

This proposal has been made to solve the above-mentioned conventional problems, and the embodiments shown in the drawings will be described below.

In FIG. 2, 11 is a vibration direction converter in the form of a thick disk, 12 is one or more vibration transmitting rods (two are shown in the drawing) installed horizontally on the side of the direction converter 11, and 13 14 is an ultrasonic transducer such as a Langevin type vibrator coupled to the end of the vibration transmission rod; 14 is a vibration transmission rod installed vertically at the bottom of the vibration direction converter 11; and 15 is an ultrasonic transducer connected to the end of the vibration transmission rod 14. A vibration radiator consisting of short cylinders connected together, the vibration direction body 1
Vibration transmission rods 12.1 installed on the sides and bottom of 1, respectively.
The length of 4 is fixed by a fixing device ( (not shown), the ultrasonic transducer 13 is located outside the cleaning tank 18, and the vibration radiator 15 is immersed in the cleaning liquid 19 in the cleaning tank 18 at an arbitrary depth. It is extended to the length of .

The vibration direction converter 11 is not limited to a thick disk, but may have a three-dimensional shape that can propagate the vibration from the ultrasonic transducer 13 in a different direction, and the vibration radiator 15 is not limited to a short cylinder. Any three-dimensional shape may be used as long as it can emit ultrasonic waves from all around.

17 is a high frequency oscillator that excites the ultrasonic transducer 13.

Next, FIG. 3 shows the other side of the present invention, in which a plurality of vibration radiators 15 are vertically installed together with a vibration transmitting rod 14 at the bottom of the vibration direction converting body 11 and are connected horizontally via a vibration transmitting rod 16. ,
An ultrasonic transducer 13 is installed horizontally along with a vibration transmission rod 12 on the side of the vibration direction converter of the part. Each rod 14 is extended to the required length as described in FIG. 2 above.

This project consists of the above-mentioned configuration, in particular, a vibration direction converter is used, a vibration transmission rod of the required length is installed horizontally on the side of the rod, an ultrasonic vibrator is connected to this rod, and the vibrator is removed from the upper part of the cleaning tank. Since the cleaning solution can be placed in a location where the cleaning solution is used, conventional concerns regarding filling, replenishing, and replacing cleaning fluid can be resolved, and work efficiency can be greatly improved.
