DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasonic
oscillator used for mosquito control, pest control or medical treatment. パ・6.。 ~ As this type
of ultrasonic wave oscillation device which exists conventionally, as shown in Fig. 1, the switch
member B which is turned ON and OFF by pivoting downward of the case main body A
incorporating ultrasonic wave oscillation means not shown. There is the one that forms a slit-like
window C in the upper part of the case main body A while attaching, and oscillates in the
direction of the arrow in the figure through the window C from an ultrasonic oscillator board
attached below the window. . However, the ultrasonic wave is oscillated only in the lateral
direction of the window portion C of the case main body because of its configuration, and the
ultrasonic action is produced in the lower part out of this area. Therefore, for example, even if it
is used at home, at a barn, at a farm, etc., it is not possible to completely prevent the damage of
mosquitoes and harmful birds from humans, animals and fruit trees. In the present invention, it is
an object of the present invention to provide an ultrasonic oscillation apparatus in which an
ultrasonic wave having a great effect for controlling mosquitoes, harmful birds or the like, or for
medical use is improved to act over a wide range. According to the configuration of the present
invention, the ultrasonic oscillator is attached to the inner central portion of the window formed
at the upper part of the case main body 12) ○, and the ultrasonic oscillator is mounted above the
case main body from the ultrasonic oscillator The present invention relates to an ultrasonic wave
generator characterized in that a reflection plate of oscillated sound waves is attached. This will

be described as follows based on an embodiment shown in the drawings. In the embodiment
shown in FIG. 2, the switch 2 to be turned ON / OFF by attaching it to the lower part of the case
main body 1 incorporating the ultrasonic wave oscillating means is attached, and the upper part
is slit-shaped A window 3 is formed. An ultrasonic oscillation board 4 is attached to an inner
central portion of the slit-like window portion 3, and an upper spherical portion of the case main
body upper portion reflects an ultrasonic wave oscillated from the ultrasonic oscillation board 4.
The reflector 5 is attached. Therefore, there are ultrasonic waves that are oscillated in the lateral
direction or obliquely upward direction directly from the window part 5 and those that are
oscillated to the lower part of the case main body after being reflected by the reflection plate 5.
The embodiment shown in FIG. 5 is for hanging or lowering and has a locking member 6 at the
upper portion of the case (3 + 本体 main body 1 and the outer portion of the window portion 3 at
the lower portion of the case main body 1). The reflection plate 5 is attached in a reverse bowl
shape, and the ultrasonic waves oscillated from the ultrasonic wave oscillating plate are all
reflected by the reflection plate 5 and oscillated toward the lower part.
Therefore, the lower part can all be affected by the action of ultrasound if it is hung in the house,
in a barn or in the stomach of a fruit tree. The embodiment shown in FIG. 4 is a suspension or
mounting combination and is particularly convenient for oscillation in the lateral direction or
downward direction, and the ultrasonic oscillation shown in FIGS. 2 to 4 according to the
application. The device can be used. A light emitting diode 7 blinks at the time of ultrasonic
oscillation, and serves to confirm the oscillation or to clarify the location at the time of use at
night. Further, the ultrasonic complex pulse waveform in this embodiment is preferable, and its
Hz number is about 7,000 H7, and depending on the application, higher or lower Hz ultrasonic
waves may be oscillated. Therefore, according to the present invention, as in the prior art, the
oscillation is only in the lateral (4) O direction, and the ultrasonic action does not reach where it
deviates from this area, and the required mosquito, harmful bird control effect etc. Unlike the
ones that can not be exhibited, the ultrasonic wave generator is operated by the action of an
ultrasonic wave oscillation board attached to the middle part of the window and a reflection plate
that reflects the ultrasonic wave oscillated from the ultrasonic wave oscillation board. In the case
of the hanging method, the ultrasonic action can be applied to the entire lower part of all local
parts, so that the medical effect, the control effect of mosquitoes, harmful birds, etc. can be
exhibited even more. is there.
