Description

Detailed Description of the Invention "Field of Industrial Application" The present invention belongs to the field of electrical appliances, in which ultrasonic energy is indirectly injected into a specific liquid via the liquid, and the cavitation phenomenon that occurs there causes the It relates to a device (hereinafter referred to as an ultrasonic oscillator) that atomizes a specific liquid and releases it into the atmosphere, and is used both as a humidifier and as an aroma diffuser.

``Prior Art'' Ultrasonic oscillators, which have traditionally been used to generate cavitation in liquids such as water using ultrasonic energy, are used for that purpose by being integrated with a container, as seen in humidifiers. ing. Therefore, the liquid used therein is directly affected by the ultrasonic oscillator, so when changing the type of liquid used, it takes time to clean the container and requires a large amount of liquid to be replaced. From doing that,
The use of liquids has been limited, such as only one type of liquid being used. In addition, double chamber systems are used in fields where ultrasonic waves are used for cleaning and painting techniques, but because the output of the equipment is large, there is no consideration given to reducing efficiency due to the presence of air, and atomization technology is often used in everyday life. It is not functional.

"Problems to be Solved by the Invention" Therefore, the present invention solves the problem that the liquid that comes into direct contact with the ultrasonic oscillator will not cause cavitation as in the conventional case.
Alternatively, the purpose is to provide an ultrasonic oscillator that can simply and efficiently generate cavitation in various types of liquids by simply becoming a substance that propagates ultrasonic energy. It is a humidifier, and the latter is provided as an aroma emitting device that combines the cavitation phenomenon of liquid with the effects of incense, which has been popular since ancient times in Japan.

"Means for Solving the Problems" The present invention stores a first liquid in a liquid chamber of a main body to which an ultrasonic oscillator is attached, and stores a container containing a second liquid in the liquid chamber to indirectly In the atomizing means for atomizing the second liquid, an air exhaust means is disposed in a liquid chamber storing the first liquid, and a container storing the second liquid is detachably attached to the liquid chamber in an airtight manner. The container is fitted with an air discharge means for discharging the air in the liquid chamber and disposed at the bottom of the container.

"Function" When used without removing the cassette container, it is used as a conventional humidifier, and when used with the cassette container attached, there is no air on the bottom of the container and inside the liquid chamber, so the container The second liquid inside is efficiently atomized.

"Example" Below, the present invention will be explained with reference to Examples.
As shown in the figure, an ultrasonic oscillator 2 is fixed to the inner upper surface of a cylindrical seat 1, and the cylinder 3 that is integrally installed on the upper part of the seat 1 communicates with the upper surface of the seat 1 through an opening 4. However, the ultrasonic oscillator 2 faces the opening 4. The cassette container 5, which is removably locked inside the cylinder 3, has a slightly conical bottom surface as an air exhaust means to prevent air from remaining on the bottom surface, and is spaced a predetermined distance from the upper end of the opening 4. and is seated on guide seat 6. Inside the cylinder 3, there is provided an enlarged chamber 7 which serves as a liquid chamber and has a diameter larger than the outer diameter of the cassette container 5 at a predetermined height from the upper end of the opening 4. A small hole 8 is drilled through the outer periphery, a blind stopper 9 is locked in the small hole 8, and an O-ring 10 is locked in the upper interior of the cylinder 3 to maintain the outer periphery of the cassette container 5 in an airtight state. ing. A cap 11 is secured to the upper part of the cassette container 5, and a small hole 12 is passed through the upper surface of the cap 11, and the inside thereof is filled with a required amount of the second liquid a. On the other hand, opening 4
The first liquid b is stored in the expansion chamber 7 and fills the space formed by the outer periphery of the cassette container 5. Note that the ultrasonic oscillator is appropriately installed inside the seat 1 and is omitted in this figure.

When the ultrasonic oscillator (not shown) is energized in this state, the ultrasonic energy from the ultrasonic oscillator 2 is propagated to the second liquid a in the cassette container 5 via the first liquid b, and the second liquid and the atmosphere are connected. Cavitation occurs at the interface of the cap 11, and water vapor is released into the atmosphere through the small holes 12 of the cap 11. When replacing the cassette container 5, do not remove the blind stopper 9 and pull out the container 5 while introducing air through the small hole 8. When replacing the container, fill the expansion chamber 7 with the required amount of first liquid, and then replace the cassette container 5. When it is inserted, air will be exhausted from the small hole 8 and excess first liquid will overflow, so at that point the blind stopper 9 is closed to complete the setting.

"Effects of the Invention" As described above, according to the present invention, the cassette container 5
By simply replacing the container, several types of fragrance can be selected and released into the atmosphere.If the container 5 and the second liquid a are used in correspondence with each other, there is no need for cleaning at the time of replacement, and the problem of scent transfer can be avoided. The purpose of the present invention is achieved by eliminating the intervention of air and combining the cavitation phenomenon, which is efficient with a small output, and the effects of fragrance. In other words, if the present invention is used in a humidifier, it will normally be used for humidification, but sometimes it can be used in a cassette container to emit a fragrance and enjoy the benefits of the fragrance, and if used in a flower vase, etc., it will be used for humidification. Dried flowers such as these have the scent of roses, and daffodils have the scent of daffodils, which has the effect of creating a more effective atmosphere.
