Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an ornamental atomizing device that is used as a moving ornament.

[Conventional technology]

Conventionally, there have been many interior products that utilize advanced science and technology or certain basic laws of nature, such as lighting fixtures made by bundling a large number of optical fibers and devices that move oil blobs in water. It has been commercialized.

Other devices of this type include, for example, Figure 3a.
As shown in FIG. 2, a piezoelectric body 21 that generates ultrasonic waves is provided on the back side of the bottom of a water tank 23 containing water 22. In this device, piezoelectric body 2
When a high frequency signal is applied to the piezoelectric body 21, ultrasonic waves are generated from the piezoelectric body 21, and these ultrasonic waves are transmitted to the water 22 in the water tank 23.
As shown in FIG. 2B, the water surface bubbles and the water 22 is atomized. Such a structure is used, for example, in a humidifier.
Further, when the output of the ultrasonic wave is further increased, a column of water comes to stand above the piezoelectric body 21, as shown in FIG. For example, the high frequency signal input to the piezoelectric body 21 at this time is 200W, and the resonant frequency is 400KHz.
It is. Since the above phenomenon is very interesting and attracts the attention of viewers, it is conceivable to use it in an ornamental atomizer.

[Problem that the invention attempts to solve]

However, the above-mentioned conventional structure has a problem in that it cannot obtain sufficient height and variation as a fountain, and is still insufficient for use as an ornamental.

[Means for solving problems]

In order to solve the above-mentioned problems, the ornamental atomizer of the present invention includes a container that contains a liquid inside, has a spherical shape with a downwardly convex bottom, and has a transparent peripheral wall. It is provided on the lower surface of the bottom, and the upper surface has a spherical concave shape corresponding to the lower surface of the bottom of the container, and converts the high frequency signal supplied from the oscillator into mechanical vibration to generate ultrasonic waves, and also transmits the generated ultrasonic waves to the It is configured to include an ultrasonic generator that focuses near the surface of the liquid in the container and an oscillator that generates a high frequency signal.

[Effect]

With the above configuration, when a high frequency signal is input from the oscillator to the ultrasonic generator, an ultrasonic wave is emitted from the ultrasonic generator whose upper surface has a concave spherical shape, and this ultrasonic wave is transmitted near the liquid surface in the container. It is converged on. This increases the energy in the area where the ultrasonic waves converge, causing the water droplets in this area to turn into fine mist and spray out in the form of a fountain.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in FIG. 1, the display device according to the present invention has a circular vessel-shaped base 1 at the bottom, and a transparent cylindrical body 2 is fitted onto the base 1. A thin bottom plate 3 curved downward in a spherical shape is provided at the lower end of the cylindrical body 2, and water 4 is accommodated inside the cylindrical body 2. The cylindrical body 2 and the bottom plate 3 described above constitute a container. A piezoelectric body 5, which is an ultrasonic generator and is curved into a spherical shape corresponding to the bottom plate 3, is attached to the lower surface of the bottom plate 3. The relationship between the radius of curvature of the piezoelectric body 5 and the amount of water 4 is set so that the vibrations generated from the piezoelectric body 5 are focused on substantially the surface of the water 4, as will be described later. The piezoelectric body 5 is made of so-called PZT, which is made by mixing and sintering zirconium oxide, titanium oxide, and lead oxide. Furthermore, since the shape of the piezoelectric body 5 is slightly deformed by sintering, by polishing it with a spherical file after sintering, the radius of curvature on the inner surface side of the piezoelectric body 5 can be adjusted to the radius of curvature on the lower surface side of the bottom plate 3. It matches the radius.

Transparent windows 6, 6 are formed on the outer peripheral side of the piezoelectric body 5 in the bottom plate 3, and a light bulb 7 is disposed in each transparent window 6. These light bulbs 7, 7
As shown in the figure, it is connected to a power source 9 via a switch 8. The switch 8 is provided on the peripheral wall of the base 1. In addition, the power supply 9 has a switch 8.
An oscillation circuit 10, which is an oscillator, is connected through the oscillation circuit 10, and the piezoelectric body 5 is connected to the oscillation circuit 10. The piezoelectric body 5 receives a high frequency signal generated by the oscillation circuit 10, converts it into mechanical vibration, generates an ultrasonic wave, and transmits this ultrasonic wave into the water 4.
It is designed to converge near the water surface to form a focal point.

Further, an upper lid 11 is provided at the upper end of the cylindrical body 2, and a spherical reflecting mirror 12 is provided at a portion inside the upper lid 11 that contacts the upper end of the cylindrical body 2. There is.

In the above configuration, when the switch 8 is turned on, the power source 9, the light bulbs 7, 7, and the oscillation circuit 10 are connected, and the light bulbs 7, 7 are turned on. Further, the oscillation circuit 10 oscillates a high frequency signal, and this signal is supplied to the piezoelectric body 5. The piezoelectric body 5 receives a high frequency signal from the oscillation circuit 10, converts it into mechanical vibration, and generates an ultrasonic wave. This ultrasonic wave is transmitted to the water 4 in the cylindrical body 2 via the bottom plate 3.
It converges around the water surface. This results in
Ultrasonic energy is focused near the surface of the water 4, generating strong vibrations in the water 4, and the water near the water surface is atomized and rises in the form of a fountain. If the frequency of the high frequency signal supplied from the oscillation circuit 10 at this time is set to about several MHz, a thin and tall fountain can be obtained.

Note that if the focal point of the ultrasonic waves emitted from the piezoelectric body 5 is too far below the surface of the water 4, the surface of the water 4 will only ripple and the water 4 will be atomized. On the other hand, if it passes above the surface of the water 4, only a column of water stands up from the surface of the water 4. Therefore, in order to form a mist of water 4 in a fountain shape, depending on the frequency of the ultrasonic wave, for example, if it is 400 KHz, it is necessary to focus the ultrasonic wave in a range of about 10 mm above and below the water surface.

Furthermore, when the switch 8 is turned on to form a fountain, the light emitted from the light bulbs 7, 7 is irradiated onto the fountain, and is also reflected by the reflector 12, illuminating the inside of the cylinder 2, creating a fantastic illusion. You can get great lighting effects. Furthermore, since the present device has a lighting function as described above, it can be used as a small and lightweight decorative tabletop lighting device. Furthermore, since no mechanical devices such as pumps are used, no noise is generated.

[Effect of idea]

As described above, the ornamental atomizer of the present invention includes a container that contains a liquid inside, has a spherical shape with a downwardly convex bottom, and has a transparent peripheral wall, and is provided on the lower surface of the bottom of the container. The upper surface has a spherical concave shape corresponding to the lower surface of the bottom of the container, and converts the high frequency signal supplied from the oscillator into mechanical vibration to generate ultrasonic waves, and the generated ultrasonic waves are transmitted to the liquid in the container. The structure includes an ultrasonic generator that focuses near the liquid surface and an oscillator that generates a high-frequency signal.

Therefore, it is possible to atomize the water contained in the container and form the atomized water into a fountain shape with sufficient height and flow variation. Therefore, when this device is used as, for example, an indoor decoration, it has the effect of being able to have sufficient functions as a viewing device.
