Description

  The present invention relates to an ultrasonic atomizer having a double structure of an outer container and an inner container.

    A conventional ultrasonic atomizer is equipped with an ultrasonic vibrator at the bottom of a container containing a liquid to be atomized, and a capillary is applied to the surface of the liquid to be atomized by applying a high-frequency voltage to the ultrasonic vibrator. Those that generate waves and atomize, those that constitute a horn on the upper part of the ultrasonic transducer inside the container and concentrate the ultrasonic flow to increase the amount of atomization, In order to atomize a chemical solution such as alkali, a container in which the container is doubled and an ultrasonic vibrator is attached to the bottom of the outer container has been proposed.

  However, in a conventional ultrasonic atomizing device that attaches a horn to the inside of a container to increase the amount of atomization by measuring the concentration of ultrasonic flow, the liquid to be directly atomized is placed in the container. If the liquid level of the liquid to be atomized is lowered, there is a problem that the atomization efficiency is lowered, and if it is necessary to atomize different types of liquids, the liquid in the container must be replaced and washed. there were.

  The problem to be solved is that the liquid to be atomized is put directly into the container, so if the liquid level of the liquid to be atomized falls, the atomization efficiency decreases.If you want to atomize different types of liquid, There was a problem that all the liquid in the container had to be replaced and cleaned.

  The present invention includes an outer container having an ultrasonic transducer fixed to the bottom, a transfer liquid placed in the outer container, an inner container placed in the outer container at a predetermined interval, and a mist placed in the inner container. And a horn attached to the bottom of the inner container. The horn is detachably attached to the bottom of the inner container.

  In the ultrasonic atomizing apparatus of the present invention, when a horn is attached to the bottom of the inner container in a double tank, it is sufficient to always put a certain amount of liquid in the outer container. It is sufficient that the number corresponding to the number of types is easy, and it is not necessary to wash each time the solution is changed, and the amount of atomization is increased, and there is an advantage that the atomization can be efficiently performed.

FIG. 1 is a side sectional view of an ultrasonic atomizer according to an embodiment of the present invention. FIG. 2 is a side view of the horn of the ultrasonic atomizer according to the embodiment of the present invention. FIG. 3 is a side view of another horn of the ultrasonic atomizer according to the embodiment of the present invention.

  In the present invention, the ultrasonic vibrator is fixed to the bottom of the outer container, the ultrasonic transmission liquid is put in the outer container, the inner container is put on the ultrasonic transmission liquid with a predetermined interval in the outer container, and the inner container An atomized liquid is put into the inner container, and a horn is attached to the bottom of the inner container.

  FIG. 1 is a cross-sectional view of an ultrasonic atomizer according to an embodiment of the present invention. An ultrasonic vibrator 2 is fixed to the bottom of an outer container 1, and an ultrasonic transmission liquid 3 is placed in the outer container 1. An inner container 4 is placed in the sonic transmission liquid 3 at a distance from the bottom of the outer container, and the atomized liquid 5 is placed in the inner container 4, and the bottom of the inner container 4 is spaced from the upper part. The fixed frames 6a and 6b attached so that the protrusions face each other are mounted, and the stepped portions 7a and 7b at the lower end of the horn 7 are fixed to the fixed frames 6a and 6b as shown in FIG. The horn 7 is hollow and configured in a conical shape, and a communication hole 7c is formed in the lower part to receive the atomized liquid 5. The upper part of the horn 7 is an ejection hole in which atomized particles obtained by atomizing the atomized liquid 5 are ejected. 7d is provided, and an oscillator 8 connected to the ultrasonic vibrator 2 at the bottom of the outer container 1 is provided on the outer side. It is mounted on the lower side of the vessel 1.

  In the ultrasonic atomization apparatus of the present embodiment configured as described above, when the oscillation output is input from the oscillator 8 to the ultrasonic vibrator 2, the ultrasonic wave is input from the ultrasonic vibrator 2 into the outer container 1. Since the atomized liquid 5 in the horn 7 of the inner container 4 is irradiated through the transmission liquid 3, the atomized liquid 5 flowing from the communication hole 7 c of the horn 7 is atomized, and an ejection hole at the upper part of the horn 7. The atomized liquid is atomized and atomized particles are ejected until the atomized liquid 5 is about 2/3 of the horn 7 and is ejected through 7d.

  Thus, in the ultrasonic atomizer of the present embodiment, if a certain amount of transmission liquid is put in the outer container 1, even if the atomized liquid in the inner container 4 becomes empty, it becomes empty. In addition, if the inner container 4 is prepared according to the number of the atomizing liquids 5 to be put in the inner container 4, it is possible to cope with atomization of different atomizing liquids 5, and the atomizing liquid 5 is replaced. There is no need to clean the inner container each time.

  In FIG. 2, stepped portions 7a and 7b are provided at the lower end of the horn 7 and fixed by the fixing frames 6a and 6b. However, as shown in FIG. 3, ribs 7e and 7f are formed at the lower end of the horn 7. By doing so, the horn 7 may be securely fixed to the fixing frames 6 a and 6 b at the bottom of the inner container 4.

  In addition, in the said Example, it can respond to diversification of the atomization liquid which wants to atomize, and does not choose the place to atomize.
