Abstract

PURPOSE:To atomize two kinds of liquid at the same time by a ultrasonic-wave vibrator by arranging each reflecting plate in divided tanks. CONSTITUTION:A tank 11 is divided into two chambers by a partititon wall 11a, and in said chambers, two kinds of liquid 12a and 12b are stored, and penetration hole 11b is drilled on the patition wall 11a, and an ultrasonic-wave vibrator 13 is fixed so as to blose the penetration hole 11b, and in the liquid in each chamber, ultrasonic-wave reflecting elements 15a and 15b are arranged which allow the ultrasonic-wave energy which is radiated from the ultrasonic-wave vibrator 13 to be reflected towards the liquid surface. This constitution permits two kinds of liquid to be atomized at the same time by one ultrasonic-wave vibrator, with a simple constitution.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasonic atomizer that atomizes a liquid by applying ultrasonic energy to the liquid. This invention relates to an ultrasonic atomization device that can

Generally, the ultrasonic atomization device illustrated in FIG. 1 is known.

That is, in the same figure, 1 is a tank containing a liquid 2 to be atomized, 3 is an ultrasonic vibrator fixed in a through hole 1a formed in the center of the bottom of the tank so as to be sealed from the outside, and 4 is the vibrator. Electrode surface 3
A high frequency oscillator is connected between a and 3b, 5 is a blowing pipe connected to the upper side of the tank 1, and 6 is a wandering fog cylinder connected to the upper surface of the tank. In such a device, when the ultrasonic vibrator 3 is excited by the high-frequency oscillator 4, ultrasonic energy is irradiated in the direction of the arrow from the surface 3a of the vibrator in contact with the liquid 2, and the liquid 2a rises from the liquid surface and spreads around the liquid. A mist 2a' consisting of a group of minute particles scattered in the air is discharged from the exhaust tube 6 by the air sent into the tank 1 from the blower pipe 5. In this case, if water is used as the liquid 2, it will be released indoors or inside the car. It can be used as a humidifying device to maintain a constant temperature, and when liquid 2 is a mixture of fragrances mixed with a solution, it can be used as an aroma device to fill the interior of a room or a car with a desired scent.It can also be used as an aroma device to fill the interior of a room or car with a scent of your choice. When used as a deodorizer, it can be used as a deodorizer to remove bad odors that accumulate in the room, and by selecting an appropriate liquid depending on the purpose, it can serve a variety of purposes.

Therefore, these ultrasonic atomizers are used alone in a room or in a car, or are incorporated into an air conditioner such as a heater, but at this time, at least two types of atomizers, e.g. If the above-mentioned humidifying device and aroma device are used in combination, the advantage of humidifying the interior of a room or a car and at the same time enjoying a fragrance of preference according to the sense of smell to create a refreshing feeling is brought about.

The present invention aims to provide an ultrasonic atomization device that can simultaneously exhibit the effects of two types of liquids as described above, and will be explained below with reference to the drawings.

In FIG. 2, reference numeral 11 denotes a liquid tank, which has two independent chambers 5 and 11 separated by a partition wall 11a erected at the center of the inner bottom surface.
, 50.

Each chamber 5, 50 contains two types of liquid, for example water 12a.
and perfume 12b are stored up to the water level. Further, a through hole 11b is bored in the partition wall Ila at a position below the liquid level. Reference numeral 13 denotes an ultrasonic transducer fixed in a through hole Ilb in the partition wall so as to be liquid-tightly sealed from one side thereof, and is manufactured in a plate shape from a piezoelectric material such as lead zirconate titanate porcelain as is known in the art. , electrodes 13a and 13b are attached to the front and back surfaces for polarization.

Reference numeral 14 denotes a high frequency oscillator connected between the electrode surfaces 13a and 13b of this ultrasonic transducer, which generates the transducer 13 at a predetermined resonance frequency.
excite.

15a and 15b are liquids in each chamber Sl and S2 of the tank 11]
A sound wave reflecting member immersed in 2a and 12b and fixed to the inner bottom surface of each chamber refracts the ultrasound energy radiated laterally from both surfaces 13a and 3b of the ultrasound transducer toward the wavefront.

The reflection angle θ of this reflecting member is normally set to 30 to 60°, and preferably set to 45° for efficiency. 16a, 16b
'' are air pipes connected to send air into the chambers Sl and S2 on both sides of the tank 11, 17 is an upper lid fitted to the upper opening surface of the tank 11, and 18 is an opening protrusion 1 in the center of the lid.
This is a mist exhaust pipe fitted to 7a.

To explain the operation of the device of the present invention, the high frequency oscillator 14
When the ultrasonic transducer 13 is driven, ultrasonic energy (
arrow) is irradiated. The irradiated ultrasonic waves are liquid] 2a,
2b and hits the inclined surfaces of 5a and 15b, and is refracted upward according to the inclination angle θ and exits from the liquid surface. At this time, the surface of each liquid 12a and 12b is activated and minute particles Mist 12a″″, 12b″″ consisting of particles
Liquid columns 12a'', 12b'' containing 2 swell up. on the other hand,
At the same time as the ultrasonic vibrator 13 is excited, the air pipes 16a, 16b
The two types of mist 12a'' and 12b'' generated in the chambers Sl and S2 are mixed and discharged from the mist cylinder 18 by the air sent into the chambers Sl and S2 in the tank 11. ,
It performs two functions at the same time, such as a humidifying effect and an aromatic effect. Next, in the embodiment shown in FIG. 3, each chamber S of the tank 11 is
The mist 12a'', 12b'' generated in the upper lid 7 is independently discharged from two mist exhaust tubes 18a, 18b fitted into the opening protrusions 17a'', 17b'' of the upper lid 7. The rest of the structure is almost the same as that in FIG. 2.

As described above, the ultrasonic atomization device of the present invention can atomize two types of liquids at the same time, so it is convenient for humidifying a room or a car and creating air at the same time. The device of the present invention atomizes two types of liquid by effectively utilizing the ultrasonic energy emitted from both sides of a single ultrasonic vibrator, so the configuration is extremely simple and the power consumption is reduced. There are benefits such as reducing
