Description 1, title of the invention
Langevin type ultrasonic vibration device
и 3 Detailed description of the invention The present invention relates to a lanzy pan-type
supersonic wave 'e using an electrostrictive vibrator made of a material such as titanic acid or
lead zirconate, a vibration device, and its object The point is (1) Increase in vibration load on
ultrasonic vibration propagation system. A support structure free from the occurrence of adverse
effects such as turbulence is obtained. (2) For example, in the use as an ultrasonic atomization
device, the generation of vibration noise from the support fixing portion is prevented. (3) The
configuration is simplified and a low-cost mass-productive vibration device is obtained. (4)
Including the related parts, make the unit into a unit, reduce the variation, and make it easy to
incorporate it into the combustion device etc. (5) For example, the combustion apparatus which
stabilizes liquid atomization. Improve the performance of applied products such as humidifiers. A
typical example of the conventional support structure of this type of acoustic wave vibration
apparatus is shown in FIG. 27 to FIG. In FIG. 27, the magnetostrictive vibrator 103 is fixed to one
end of the front metal body 1 o ? with an adhesive, and the vibration of% wavelength is
generated at the edge of the vibrator 103 and the atomization surface 1021 of the front metal
body 100. A projecting piece 101 is integrally provided at a node () -do) position and fixed to a
supporting member formed of a main body 104 such as a combustion apparatus. FIG. 28 shows a
case where the electrostrictive vibrator 13 is separated, and a concave portion 105 is formed in
the vicinity of the portion of the moving part of the @ part metal body 15 of the ship wavelength.
It is fixed in place. 20 is a rear metal body, and 16 is an atomization surface. In FIG. 29, a
projection 107 is formed at the node position of vibration of the body 15 to the front part metal,
and is fixed to the apparatus main body. In FIG. 3O, the rear gold metal body 2o is formed in the
14-04-2019
1
same length as the front metal body 15, and fixed in the same manner as in FIG. 28 at the node
position of vibration of the rear metal body 2o. In FIG. 31, the node positions of the vibration of
the front metal body 15 and the rear metal ring 20 are held by the disc 108 and the bolt 109
with EndPage: 2 and fixed to the apparatus main body. As mentioned above, although there are
various support structures of a vibration apparatus conventionally, it has the following problems.
(1) As shown in FIGS. 32 and 33, the propagation of the vibration of the ultrasonic vibration
apparatus is performed. Looking at the amplitude distribution, in FIG. 32, vibration nodes are
formed at the position of the electrode plate 14 held by the vibrator 13 and at the position of the
arrow wavelength ?. This node is the point of the circular soil, and in fact, in order to support
and fix the% wavelength node in particular, a certain width is always required, so the propagation
of vibration to the supporting and fixing member is avoided. Absent.
Further, in the vibration system, the node position of the vibration is also easily moved due to the
temperature change, the variation of the characteristics of the vibrator or the like, and the load
condition. From the position of the node of the wedge wavelength to the atomizing surface 16,
the amplitude is rapidly expanded, and by moving the node, the support fixed position enters the
middle of the amplitude being greatly expanded, to the support fixing member. In addition to the
vibration, the efficiency is deteriorated and the metal parts in the audible range are likely to be
generated at the support fixing portion. Thus, fixing at the wavelength of the front metal at%
wavelength has many undesirable factors. The node of the vibration formed at the position of the
electrode plate 14 held by the two vibrators 13 does not move even if the resonant vibration
frequency changes, and the amplitude is small and always constant even in the vicinity Because
there is, it is preferable to support and fix this. Although it is ideal to support and fix the
electrode plate 14 itself, it is impossible due to problems such as strong supervision and
insulation. As described above, the Langevin-type ultrasonic vibration device has several
problems. FIG. 33 shows an amplitude distribution of an ultrasonic vibration apparatus using a
magnetostrictive vibrator made of ferrite or the like. Supporting and fixing the vibration node of
the front metal body 100 exhibits the same tendency as the above-mentioned Lange-Pan
ultrasonic vibration device. The other node is located in the vibrator 103 and can not be
supported and fixed here. (2) In the case shown in FIG. 27, the projecting piece 101 is formed
integrally with the front part 100, but it is difficult to process and the cost is high. (3) In FIG. 28,
the fixing is achieved by fitting the recess 105 of the front metal body 15 and the support rod
106. The support rod 106 needs to be in strong contact with the recess 105 of the front metal
body 15, which tends to cause a large load on the vibration system. Furthermore, metal noise is
likely to occur at the contact portion. (4) The one shown in FIG. 29 exhibits the vibration state
shown in FIG. 32, and has the problem shown in (1) above. (5) The problem shown in FIG. 30 is
the same as that of FIG. 28 and the distance from the support fixing portion to the atomization
surface is long, and the error in dimension assembly is large. (6) In FIG. 31, the node position is
held by the disc 108 and the bolt 1 o 9 or the load on the vibration system becomes very large
for the reason described in (1). (7) In this type of ultrasonic vibration apparatus, radial vibration
14-04-2019
2
is also generated along with axial vibration, which can not be transmitted to the supporting /
supporting member. Therefore, if the supporting and fixing method is not appropriate, the load
on the vibrator is increased, the efficiency of the vibration propagation to the atomization surface
is deteriorated, and a metallic sound in the audible range is easily generated from the joint.
(8) In the conventional supporting and fixing, there are many problems in the serviceability as
well as the lack of mass productivity in the case of assembling and disassembling of the
combustion apparatus etc. to the main body. (9) In the past, one end of a metal pipe for
introducing liquid fuel or the like to the atomization surface is directly connected and fixed to the
front metal integrally. Therefore, the vibration is transmitted from the front metal body to the
pipe, the load of the vibration system is increased, and a ringing noise is easily generated at the
fixed portion between the other end of the pipe and the main body of the combustion apparatus.
(10) At the time of combustion using the above-mentioned vibration device, if the positional
relationship between the atomizing surface 16 or 102 and the two ignition electrode rods is not
always appropriate, it will be misfired and the atomized particle crane relatively The above 7
positional relationship is important because it is prone to unstable movement. In the
conventional ultrasonic combustion device, when the ultrasonic vibration device is attached to
the main body EndPage: 3 or removed from the main body, the positional relationship between
the atomization surface 16 or 102 and the ignition electrode rod tends to change Met. The

on the front metal body 16 and the rear metal body 20, and integrally fixes the intermediate
support 24 and the holding body 82 through the pin 81 between the two flanges 79 and 80. It is
the composition that it was made to do. 23 to 24 show the position of the shock absorbing
material 84 made of rubber or the like between the outer peripheral surface of the front metal
body 15 near the vibrator 13 side and the receiving 83 of the projecting piece 25 of the

the vibrator 13, and the intermediate support 24 may be fixed in the same manner as described
above. Next, the operation of the combustion apparatus shown in FIG. 1 will be described. First,
when high frequency power is applied to the vibrator 13 from an ultrasonic oscillator (not
shown), it resonates in the thickness direction at a frequency set to 28 to 50 KH2 and propagates
while the amplitude of vibration is expanded by the front metal body 15 The surface 16 is
ultrasonically vibrated. Still further, the motor 4 is energized to rotate the blades 6, so that the
combustion air is supplied to the air passage 3 and is ejected from the air control body 8 in front
as a swirling flow. -10,000, air entering the inside of the inner cylinder 2 from the plurality of
holes 11 provided in the inner cylinder 2 flows forward along the cooling end of the ultrasonic
vibration device 12, EndPage: 5. A high voltage of about 1 KV from the transformer is applied to
the two electrode rods 44 for ignition to generate a discharge spark near the atomizing surface
14-04-2019

16. Next, the solenoid valve 53 is energized to open the valve 52 to supply the liquid fuel to the
FW layer surface 16. The fuel is atomized on the atomizing surface 16 to be ultrasonically
vibrated, and is ignited by the discharge spark from the electrode rod 44, and mixed with air in
the combustion cylinder 10 to form a flame 57. This combustion apparatus is used as a heat
source for a hot water boiler or the like. In addition, the above-mentioned ultrasonic vibration
apparatus can be used as an ultrasonic atomization apparatus which atomizes a liquid, in order to
perform coating etc. With regard to the support and fixing of the ultrasonic imaging apparatus of
this type, the conventional problems are as described above, and the operation and effects of the
present embodiment and the other embodiments that address this are as follows. O) A Langevintype ultrasonic vibration device in which an electrostrictive vibrator is sandwiched between
metal members in the front and rear parts, and characterized in that this support fixed position is
provided in the vicinity of the vibrator It is said that. The conventional supporting and fixing
structure of this type of ultrasonic vibration apparatus is shown in FIGS. 27 to 31, and this
problem is as described above. The position of the front metal body and the rear metal body in
the vicinity of the vibrator has a relatively small vibration amplitude as apparent from FIG. 32,
and the vibration node formed at the position of the electrode plate between the two vibrators 1
Since no movement occurs due to load fluctuation etc., the amplitude in the vicinity of the
vibrator does not change either and is always stable. The load due to the rigid support and
fixation is also very small and there is no problem in practice at all, and the propagation of the
imaging motion to the support member is also small, so it is easy to prevent the generation of the
hammer noise. Further, the node position of the% wavelength of the front metal body
conventionally supported has the maximum internal stress due to the imaging.
On the other hand, the internal stress is small in the vicinity of the vibrator, and the basic
configuration described above is preferable from this point as well. In addition, the intermediate
support is fixed at a position near the vibrator of the front metal body or the rear metal body to
be unitized, and further fixed to a main body such as a combustion apparatus through the
intermediate support, the whole front horse The cutting process is simple and the material cost is
low since it is not necessary to enlarge the support fixing flanges provided on the body or the
rear metal body. It is also possible to fix the intermediate support directly to the front or rear
metal vibrator near the vibrator without providing a flange. (2) Connection with the intermediate
support by forming a flange integrally with the front metal body or the rear whole body. Since it
is easy to fix, and the flange can be finished with high precision by cutting and fitting, variations
in assembly dimensions can be reduced when the ultrasonic imaging device is incorporated into
a main body such as a combustion device. (3) The ultrasonic vibration caused by the vibrator
resonates in the longitudinal direction (axial direction) and also generates some vibration in the
lateral direction (radial direction). The components of the longitudinal vibration and the
transverse vibration propagate to the seven rungs formed in the front metal body or the rear
metal body. Therefore, as shown in FIGS. 11 and 12, the inner peripheral edge portion of the
flange is a thin plate thickness of 0.5 to 1 Tm, and the outer peripheral edge portion is a plate
14-04-2019
6
thickness of 1.5 to 2.5 mm. As a result, the type of vibration propagation to the outer periphery
of the 7 runes is reduced, and a structure with no problem in terms of strength is obtained. Even
if a plurality of slits or a plurality of holes are formed on the inner peripheral portion of the
flange as shown in FIG. 18, the same effect as the above (3) can be obtained. (4) When the flange
is provided separately as shown in FIG. 13 and the flange is integrally formed with the IiT portion
metal body even if it is positioned between the vibrator and the body in the entire front part or
rear part, as shown in FIG. And the same as the intermediate support. In this case, 7 rungs can be
manufactured as a single part, and unnecessary processing is unnecessary. . In addition, as
shown in FIG. 14, separate flanges may be fixed by electric welding or an adhesive, and as shown
in FIG. 16, a method in which both are added by screw connection is also possible. (1) A separate
flange may be formed of a resin material. In this case, the fixed part between the flange made of
resin material and the intermediate support prevents the generation of metallic noise due to the
contact of both members. EndPage: 6 (6) As shown in Figure 15, either of the types of ultrasonic
vibrators in which the vibrator is held by the clamping flanges formed on the front and rear
metal bodies and a plurality of bolts Since the intermediate support can be fixed to one of the
tightening flanges, the ultrasonic vibration device can be miniaturized and the support can be
easily fixed as compared with the prior art.
(6) As shown in FIG. 22, it is possible to fix 7 flanges facing each other to the front metal body
and the rear metal body by holding the intermediate support between them without using any
screws etc. . (7) The intermediate support is formed annularly and provided with a plurality of
projecting pieces, and the propagation of vibration to the projecting pieces by fixing the
projecting pieces to the front metal body or the rear metal body itself or to the 7 runge portion
As a result, the flame can be easily detected and confirmed from the rear through the space
between the projecting pieces of the intermediate support. In addition, air can also be moved
through the gap between the air gaps 1 to increase the cooling effect of the vibrator and the rear
metal. 'X (8) As shown in FIG. 2, the ultrasonic vibration device and the intermediate support are
provided by inserting the flange into the projecting piece of the intermediate support, inserting
the flange into this pin, and further holding the 7 flanges by the holding plate. It is possible to
reduce the dimensional variation in making a ? connection with the body and to facilitate
assembly and disassembly. (9) By interposing an elastic body such as rubber between the flange
and the projecting piece, generation of metal noise generated from the contact portion between
the flange and the projecting piece can be eliminated, and the elastic body can be reduced in size.
Since the presser plate is fixed in a state in which the foot amount is pressed down, the flange
and the projecting piece can always be fixed with a single force. (10) Vibration from the contact
surface of the intermediate support and the flange, or the contact surface between the hole of the
flange and the bin of the intermediate support, etc., by providing resin coating on the surface of
the flange or a plurality of holes provided in the flange Generation of metallic noise due to By
forming it, it is possible to prevent generation of metallic noise due to vibration on the contact
surface with the ultrasonic vibration device, the contact surface of the combustion device or the
14-04-2019
7
like. (12) By interposing a washer or the like between the intermediate support and the
ultrasonic vibration device and fixing with a small contact area, propagation of vibration from the
ultrasonic vibration device to the intermediate support can be reduced. In addition, it is possible
to reduce the propagation of vibration from the intermediate support to the body such as the
combustion device by fixing a washer or the like between the intermediate support and the body
such as the combustion device with a small contact area. it can. 1 ? in (13) by providing a means
for reducing and attenuating the propagation of vibration to each of the fixed portion between
the 1 support and the +1 support and the ultrasonic vibration device and the fixed portion
between the intermediate support and the main body such as the combustion device. The main
body of the combustion apparatus or the like is not significantly vibrated and the operation of
the ultrasonic vibration apparatus is also stabilized. (14) The fixed portion between the
intermediate support and the ultrasonic vibration device or the fixed portion between the
intermediate support and the main body of the combustion device or the like 1. A resin film is
formed on the surface of the metal material or made of resin material By using a screw, it is
possible to prevent the generation of metal noise due to vibration at the fixed part.
(15) When the liquid passage portion of the front metal body and the pipe are fixed by contact or
the like and the other end of the pipe is fixed to the main body of the combustion device, etc.
(When the pipe bends or twists to the fixed part between the front metal body and the pipe, the
bending force is 70%, and there is a problem that the fixing becomes incomplete and the
vibration characteristics of the ultrasonic vibration device are adversely affected. . On the other
hand, as in the above embodiment, the intermediate support and the ultrasonic vibration device
are integrally fixed, and the middle of the pipe is fixed to the intermediate support. Since the
pipes can be integrated into one unit, the above-mentioned intermittent point does not occur. (16) The liquid passage portion of the front gold body and the pipe directly. When fixed with
adhesive etc., there is a lot of propagation of vibration from this front metal body to the pipe, and
it is easy to generate metallic noise due to vibration at the other endPage: 7 end fixing part of lcrew and load of ultrasonic vibration device Is not a good dog. Therefore, by interposing a shock
absorbing material such as rubber between the front metal body and the pipe, the vibration
propagation to the pipe can be remarkably reduced, and the conventional problems do not occur.
Furthermore, by interposing the buffer material also in the fixed portion of the intermediate
support and the pipe, it is possible to prevent the generation of metallic noise due to the
vibration in this portion. (17) By combining the ignition electrode rod with the intermediate
support and combining it with the ultrasonic vibration device, the positional relationship between
the layer surface and the electrode rod can always be maintained properly, and the ignition
characteristics become reliable, No excessive oil deposits on the ignition electrode. (18) As shown
in FIG. 9 and FIG. 10, the middle of the pipe for liquid supply is fixed to a flood and the ultrasonic
vibration device and the pipe are integrated into one unit, the same effect as the above (15)
There is. By transmitting and fixing a buffer material between the flange and the pipe, it is
possible to prevent the propagation of vibration. In addition, fixing the ignition electrode to the
14-04-2019
8
flood has the same effect as the above (17). As described above, in the Lanozy-Vano ultrasonic
vibration device according to the present invention, the plurality of electrostrictive vibrators are
held by the front metal body and the rear metal body, and a position near at least one of the two
metal bodies is held. The intermediate support is fixed to the support, and the intermediate
support is attached to the support member, so that stable vibration S% can be exhibited without
unnecessary load on the vibration system. It is possible to prevent the generation of unpleasant
gold tones due to vibration.
