Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle type cleaning device, which is a handle type ultrasonic cleaning device capable of ultrasonically cleaning only a local portion of an object to be cleaned. The present invention is widely applied to everyday life, machinery, electronics, dentistry, crafts, jewelry, food, etc.

[0002]

2. Description of the Related Art In the conventional ultrasonic cleaning, an object to be cleaned is put in water (liquid) in a container such as a tank, and water (liquid) in the container is put in the container.
Cavitation is generated in the water (liquid) in the container by applying ultrasonic waves to the. The object to be cleaned is cleaned by the cleaning effect of cavitation. The conventional method is. A larger water (liquid) container than the object to be cleaned is required. . Depending on the conditions under which cavitation is generated, a larger wastewater ultrasonic generator is required for larger containers. . It is not applicable to things that cannot be disassembled or cannot be put in a container, such as human teeth, carvings of buildings, and parts of machinery. The ultrasonic cleaning device is large and expensive. Is not suitable for cleaning only local areas.

[0003]

The conventional method requires a larger water (liquid) container and a larger wastewater ultrasonic generator than the object to be cleaned, and is not suitable for cleaning only the local part of the object to be cleaned. INDUSTRIAL APPLICABILITY The present invention is a hand-held cleaning device having an ultrasonic cleaning function capable of cleaning only a local part without requiring a large container, a large ultrasonic generator, and the need to put an object to be cleaned into water (liquid). is there.

[0004]

[Means for Solving the Problem] Ultrasonic waves are applied to stationary water (liquid) in a container such as a conventional tank to generate water (liquid).
Unlike the method for cleaning the object to be cleaned in the above, the present invention inhibits the flow of water (liquid) and forms a water pool. This is a method in which ultrasonic waves are applied to a flowing water pool to generate cavitation, and the portion of the object to be cleaned that is in contact with the water pool is washed.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION As in the embodiment of the present invention shown in FIG. 1, the embodiment comprises an ultrasonic cleaning head, a handle connected to the ultrasonic cleaning head, a water supply source and an ultrasonic drive source. The ultrasonic cleaning head has a water reservoir space made of a material capable of blocking the flow of water. An ultrasonic generator is attached to the rear part of the space, and a launch port for pouring water (liquid) into the space is provided on the side of the ultrasonic generator. Pass the hose and electric wire inside the handle to connect the water supply source and the ultrasonic drive source. It has a structure that allows the liquid sent by a hose to easily form a water pool between the space made up of a soft material at the tip and the wash product. During use, the opening of the space hits the surface to be cleaned of the object to be cleaned, and water (liquid) forms a water pool in the space due to the obstruction of the surface to be cleaned. The ultrasonic waves generated by the ultrasonic generator behind the space act on the water pool to generate cavitation in the water (liquid).
Cleaning is performed by peeling and emulsifying the dirt adhered to the surface to be cleaned by the action of cavitation. The present invention is:
Ultrasonic cleaning of only a part of the object is possible. 2. Since less water (liquid) is used, less ultrasonic power is required.

[0006]

Example 1 Ultrasonic Toothbrush FIGS. 2 and 3 show an example of an ultrasonic toothbrush. The ultrasonic toothbrush is composed of a head and a handle. The head has bristles arranged like a regular toothbrush. The hairs around the ultrasonic generator are arranged with a slightly high density so that water (liquid) does not easily pass therethrough, and a space where water (liquid) easily collects is formed in front of the ultrasonic generator. A piezoelectric ultrasonic generator is located at the bottom, and there is a water outlet just there. Behind the handle, a water supply (liquid) hose and an electric wire for driving the ultrasonic generator are connected separately to the tank and the ultrasonic transmission source. In use, ultrasonic waves hit a brush against a tooth to form a pool of water (liquid) sent by a hose between the space formed by the bristles at the tip and the tooth. An ultrasonic wave generated by an ultrasonic wave generator installed behind the water pool causes cavitation, which makes it difficult for the toothbrush to remove the stubborn plaque on the surface of teeth, dirt between teeth, and caries. Peel off and emulsify the dirt in the hole of
It can be poured into flowing water (liquid). Where water (liquid) is likely to accumulate, dirt is usually likely to accumulate and plaque is easily generated. In the present invention, since only that portion is ultrasonically cleaned, it can be efficiently cleaned. Since the brush of the ultrasonic wave of the present invention has a structure similar to that of an ordinary toothbrush, the Bragg, saliva, etc., which are difficult to wash with ultrasonic waves, can be brushed off like a normal toothpaste. Since the volume of the water pool formed between the tooth and the ultrasonic wave between the brushes is small, the ultrasonic power required to generate cavitation is in mW. Its ultrasonic power has very little effect on the human body.

[Embodiment 2] Handle type ultrasonic local cleaning device Fig. 1 shows an embodiment of a handle type ultrasonic cleaning device. The handle type ultrasonic cleaner consists of a head and a bundle. A space having water (liquid) that is likely to collect in front of the ultrasonic wave generator is formed around the ultrasonic wave generator at the head portion with a material having soft and constant water permeability such as sponge. A piezoelectric ultrasonic generator is placed at the bottom of the space, and there is a water outlet next to it. Behind the handle, a water supply (liquid) hose and an electric wire for generating ultrasonic waves are connected separately to the tank and ultrasonic wave source. At the time of use, hit the handle type ultrasonic cleaner to the part to be cleaned of the object to be cleaned, and form a water pool between the space composed of the soft material at the tip of the water (liquid) sent by the hose and the surface to be cleaned, The ultrasonic waves generated by the ultrasonic generator attached to the back of the empty space act as a pool of water, which causes cavitation, stubborn deposits on the surface that do not fall off during normal cleaning, dirt that fills the gap, Dirt in the holes can be emulsified, peeled off, and poured into water (liquid). Since the volume of the water pool formed between the object to be cleaned and the handle-type ultrasonic cleaner is smaller than that of the conventional tank type, the ultrasonic generator that causes cavitation can be made smaller than the tank type. In this method, only the local parts can be cleaned, or large parts can be cleaned locally.

[0007]

As described above, the present invention realizes a handle type ultrasonic cleaning device capable of locally cleaning an object by generating and utilizing a water pool between the ultrasonic generator and the object to be cleaned. Expanded the application range of sonic cleaning. The present invention is suitable not only for cleaning applications but also for emulsification and atomization.
