DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for
automatically removing sputum from a room, a warehouse or the like. Than before! It is known
that the コ is extremely sensitive to the ultrasonic waves in the frequency band of 2KH, 2KH to
コ JKH, and the ultrasonic waves in this frequency band are generated to prevent this from
invading from the outside. It is done. The purpose of the present invention is to prevent the
invading moths from invading the inside by using the ultrasonic waves described above, and to
completely eliminate the moths that have already infiltrated a specific area, such as a room or a
warehouse, with seven exterminating devices. is there. The present invention will be described in
detail with reference to the embodiment shown in the drawings. The ultrasonic wave generator l
includes an oscillator l for emitting ultrasonic waves in a frequency band of 22 KH to 24 KH.
Such an oscillator l emits a large amount of ultrasonic waves in a direction orthogonal to the
oscillator, and weakly in the direction of the oscillator surface perpendicular to this. By providing
the member 3 for directing the ultrasonic wave in the direction in which a large amount of
ultrasonic waves are generated, the transmission distance through which the ultrasonic wave of a
constant intensity is transmitted is increased, and its directivity is shown in FIG. Become. The
ultrasonic wave generator l configured in this way is placed on the turntable μ. The turntable cobuddha is preferably located in the center of the room or in the center of the warehouse, but it is
not necessarily limited to the center. axis! 1, the member 7 interlocked with the drive shaft 7 of
the motor gear may be fixed, the rotation of the drive shaft 7 may be decelerated, and the
turntable t may be pivoted in a fixed direction about the entire center of the rotary wheel j, It is
more likely to oscillate back and forth within a common angle C such as iroo or OQ). Reference
numeral 12 denotes the bearing of the rotation axis j. The slip ring t is disposed on the rotary
shaft, and the power of the power supply IO is always supplied to the oscillator 2 even if the
oscillator rotates with the turntable or reciprocates via the flange I /. , Which is configured to
sustain that oscillation. Since the present invention is configured as described above, the
ultrasonic waves with a large communication distance scan the entire interior of the room or the
warehouse where the wind always needs to be eliminated, and there is a sense of discomfort or
fear to the user. Can be removed from the room or in the warehouse, and as the turntable μ
rotates or reciprocates as in the present invention, the ultrasonic waves applied to the eyebrows
repeat the intensity, so the eyebrows become ultrasonic waves. On the other hand, it is
characterized in that it is chronic and prevents the effect from being reduced. If the rotational
speed or vibration speed of the turntable μ becomes too fast, mechanical noise is emitted, and if
it becomes too slow, the effect of extermination is lost, but preferably, it is 1 revolution or l
oscillation in 10 seconds. It is preferable that the speed of one revolution or l oscillation in l♂O
sec is preferable. Furthermore, since the extermination of hemorrhoids according to the present
invention is an ultrasonic wave, it goes without saying that it is harmless to human beings and
The present invention automatically prevents the invading of the coffin into the alert area, and
removes the invading coffin by removing it from the wind or the inside of the warehouse from
the wind damage. is there.
