  Hereinafter, embodiments of an ultrasonic atomizer according to the present invention will be described in detail with reference to the accompanying drawings.

First embodiment

  First, a first embodiment of the ultrasonic atomizer will be described. FIG. 1 is an external perspective view showing the ultrasonic atomizer of the first embodiment. FIG. 2 is a block diagram showing the inside of the apparatus for explaining the ultrasonic atomizing apparatus.

  1 and 2, reference numeral 1 denotes a main body, and a container portion 2 and a tank portion 3 are provided inside the main body 1. In this container part 2 and the tank part 3, the liquid 4 to be atomized is accommodated. The liquid 4 is composed of, for example, water for humidifying a room or the like, or a chemical solution such as a deodorant or a fragrance. An ultrasonic vibration unit 5 is provided below the container 2, and the vibration unit 5 includes an ultrasonic vibrator 50 such as a piezoelectric element and an oscillator 51 for vibrating the ultrasonic vibrator 50. I have.

  A blower fan 7 is provided on the inner wall surface of the main body 1. In the atomization operation, the ultrasonic vibrator 50 is ultrasonically vibrated to vibrate the liquid 4 in the container portion 2, thereby generating a liquid column 4 a on the liquid 4. Further, the atomizing particles 4b are separated from the liquid column 4a by driving the blower fan 7 with a motor or the like (not shown) and applying wind force to the liquid column 4a. The blower fan 7 may be provided on the lower surface inside the main body 1 to blow air from below to the liquid column 4a.

  A particle spray pipe 8 for spraying the atomized particles 4 b upward is provided on the upper part of the main body 1. The particle spray pipe 8 is open at the top and bottom, and the bottom opening is connected to the upper surface of the main body 1. As a result, the atomized particles 4 b are sprayed from the spray opening 8 a of the upper opening through the particle spray pipe 8 by the blowing of the blower fan 7.

  And as the liquid 4 in the container part 2 is atomized and decreases, the liquid 4 in the tank part 3 is supplied to the container part 2, and the liquid 4 in the container part 2 is configured to be a constant amount. Yes. Furthermore, the tank unit 3 is detachable from the main body 1 in order to replenish the liquid 4 in the tank unit 3.

  An injection unit 10 is provided on the upper portion of the main body 1. This injection means 10 injects the upper air 12a along the outer periphery of the spray port 8a of the particle spray pipe 8, and ejects the atomized particles 4b sprayed from the spray port 8a upward by this air injection. . In the present embodiment, the injection means 10 includes an air injection pipe 11 and an injection fan 12.

  The air injection pipe 11 is provided substantially concentrically outside the particle spray pipe 8. A gap 13 is formed between the particle spray pipe 8 and the air injection pipe 11. Therefore, the gap portion 13 is provided along the outer periphery of the spray port 8a of the particle spray pipe 8, and an injection fan 12 that sends the upper air 12a through the gap portion 13 is provided.

  By driving the jet fan 12, the upper air 12a is blown into the gap 13 and the upper air 12a is jetted along the outer periphery of the spray port 8a. By this upper air 12a, the atomized particles 4b sprayed from the spray port 8a are ejected upward by a lift-up action. Thereby, since the wind speed and the air volume of the atomized particles 4b are increased, the particles 4b can be spread throughout the room or the like in a short time.

  In this embodiment, the injection port 11 a of the air injection pipe 11 is made lower than the spray port 8 a of the particle spray pipe 8. As a result, the effect of drawing the particles 4b from the spray port 8a into the portion of the upper air 12a of the injection port 11a can be promoted, and the atomized particles 4b can be lifted up to further increase the wind speed and volume.

  In this embodiment, the wind speed V2 of the upper air 12a from the injection port 11a is larger than the wind speed V1 of the particles 4b from the spray port 8a (V1 <V2), and the wind force of the blower fan 7 and the injection fan 12 is set. Is adjusted. Thereby, it can be ejected upward in a state where the wind speed and air volume of the particles 4b are increased by the attracting action of the upper air 12a ejected from the ejection port 11a.

  According to the inventor's experiment, in the conventional ultrasonic atomizer, the height of the atomized particle 4b sprayed from the spray port 8a of the particle spray pipe 8 is about 30 cm, and the particle 4b is around the device. The particles 4b could not be diffused throughout the room. However, by providing the injection means 10 according to the present invention, the height of the atomized particles 4b increased to 2 m or more, and the particles 4b could be spread throughout the room or the like in a short time.

  Furthermore, the inventor measured the negative ion effect by the ultrasonic atomizer of the present invention. 3A and 3B are diagrams for explaining the measurement result of the negative ion value in the ultrasonic atomizer, where FIG. 3A is a plan view and FIG. 3B is a side view. Using the center of the spray port 8a as a reference, negative ion values were measured using distances of 50 cm, 100 cm, 150 cm, and 200 cm and heights of 0 cm, 50 cm, 100 cm, and 150 cm as measurement points in the direction of the arrow shown in FIG. The measurement results are shown in Table 1 below. In addition, since the spray port 8a and the air injection port 11a are circular and face upwards, the measurement results are almost the same in the entire periphery of the spray port 8a.

  As is apparent from Table 1 above, a high negative ion value is measured even at a height and distance that are very far from the spray port 8a. That is, by configuring the ultrasonic atomizer as described above, the atomized particles can be diffused over a very wide area and spread throughout the room.

  Next, modified examples of the particle spray pipe and the air injection pipe will be described. FIG. 4 is a schematic cross-sectional view for explaining a modified example of the particle spray pipe and the air injection pipe, where (a) shows a first modified example and (b) shows a second modified example.

  As shown in FIG. 4A, in the first modification, the particle spray pipe 8 is formed such that the diameter φ2 of the spray port 8a is larger than the pipe diameter φ1. The large diameter portion 8b of the diameter φ2 portion has a predetermined height, and the air injection pipe 11 is also large at the injection port 11a so that the gap portion 13 has a constant distance along the shape of the particle spray pipe 8. It is a diameter. In this example, the diameter φ1 is about 4 cm and the diameter φ2 is about 9 cm.

  In this way, the spray port 8a has a large diameter, and the wind speed of the particles 4b is drastically reduced to cause a liquid and gas separation phenomenon, whereby the large diameter particles 4b are dropped and only the small diameter particles 4b are removed. Spraying can be performed, and stickiness in the room due to the particles 4b can be reduced.

  Further, as shown in FIG. 4 (a), the vertical distance L from the lower end 8c of the large diameter portion 8b to the upper end 11b of the air injection pipe 11 is configured to be 1.5 times or more the radial direction distance S of the gap portion 13. Has been. In this example, the distance S is 1 cm and the length L is 3 cm. By comprising in this way, it can eject from the spray port 8a in the state which increased the wind speed and air volume of the particle | grains 4b.

  As shown in FIG. 4B, in the second modification, a part of the particle spray pipe 8 is a large diameter portion 8b having a diameter φ2 larger than the pipe diameter φ1, and again at the upper spray port 8a. The original diameter is φ1. In this example, similarly to the first modification, the injection port 11a of the air injection pipe 11 has a large diameter along with the shape of the particle spray pipe 8. The large-diameter portion 8b can be provided in two or more stages.

  Then, as described above, the large-diameter portion 4b can drop the large-diameter particles 4b, and by constricting the spray port 8b, the wind speed of the particles 4b is increased again to the original speed, and the whole room or the like Can improve the diffusion capacity.

  In addition, an injection means may provide a some small diameter air injection pipe in the outer periphery of the spraying opening 8a of the particle spray pipe 8, and may inject upward air from each injection pipe. Further, the present invention can be implemented even when compressed air is jetted by an air compressor or the like. Further, by providing a heater or the like inside the main body 1, the heated particles 4b can be sprayed to warm the room.

FIG. 8A is a perspective view showing a porous body, and FIG. 8B is a perspective view showing a fall prevention part. FIG. 9 is a cross-sectional view showing the vicinity of a spray port of a particle spray pipe to which a porous body and a fall prevention unit are attached.

  As shown in FIG. 8A, the porous body 80 is composed of a circular metal plate or the like having a large number of small holes 80b (the holes 80b are partially omitted in the drawing, but the entire porous body 80 is shown). And a bulging portion 80a bulging in an arc shape is provided substantially at the center. As shown in FIG. 8B, the fall prevention unit 81 is formed of a circular resin body or the like, and an opening 81a is provided at or around the center.

  As shown in FIG. 9, a porous body 80 and a fall prevention portion 81 are attached near the spray port 8 a in the particle spray pipe 8. In this embodiment, the particle spray pipe 8 is provided with a large-diameter portion 8b having a large spray port 8a. The large diameter portion 8b is provided with a substantially horizontal placement portion 8d at the lower end 8c, and is narrowed and connected to the pipe diameter.

The fall prevention unit 81 is for preventing small items from falling into the container unit 2 through the particle spray pipe 8 when small items fall on the particle spray pipe 8. Moreover, this fall prevention part 81 has a function which complements the porous body 80 and drops the particle | grains 4b of a big diameter.

  10 and 11 are views for explaining an attachment different from the above attached to the particle spray pipe 8. FIG. 10 is a perspective view showing a tornado forming body. FIG. 11 is a cross-sectional view showing the vicinity of the spray port of the particle spray pipe to which the tornado forming body is attached.

  As shown in FIG. 10, the tornado forming body 83 includes a protruding portion 83 a that protrudes substantially in the center. The protrusion 83a has a trapezoidal cylindrical shape with an upper wall, and has a large number of small holes 83b. The tornado forming body 83 is made of resin, for example. As shown in FIG. 11, a tornado forming body 83 is attached in the vicinity of the spray port 8 a in the particle spray pipe 8. The tornado forming body 83 is placed on the placing portion 8d with the protruding portion 83a facing upward. Similar to the above, the tornado forming body 83 is hooked on the hooking portion 82.

Further, the particles 4b are sprayed upward in a tornado shape by the protruding portion 83a of the tornado forming body 83 and the lift-up action of the upper air 12a. Thus, the particles 4b can be lifted upward while being efficiently mixed and stirred.

  FIG. 12 is a perspective view showing an ion generator. As shown in FIG. 12, the first air flow path 120 is formed by the duct portion 120a. A pair of jet fans 12, 12 'are connected to the duct portion 120a. The upper air 12a from the jet fans 12 and 12 'is blown out from the blowout port 120b provided in the duct part 120a and sent to the first air flow path 120 in the duct part 120a. Furthermore, the ion generator 9 is provided in the first air flow path 120. Thereby, ions can be put on the upper air 12a blown out from the outlet 120b, and the ions can be supplied together with the particles 4b into the whole room or the like.

The ground body 91 is a metal band such as a copper foil, and is connected to a ground wire (not shown) and kept at a ground potential. The ground body 91 is wound around the outer periphery of the duct portion 120a so as to be easily attached. The ground body 91 may be a conductive film formed by applying a conductive paint.

Then, negative ions (which may include positive ions) are added to the upper air 12 a from the injection fan 12 by the ion generator 90. At this time, the duct portion 120a is not charged due to the action of the ground member 91, and the charge is eliminated. Therefore, it is possible to eliminate a factor that hinders the passage of ions added to the upper air 12a. Thereby, most of the negative ions generated by the ion generator 90 can be released into the room or the like.
The ion generator 90 and the earth body 91 may be attached to a place where the upper air 12a communicates, or may be attached to the second air flow path 121 or the air injection pipe 11 or the like.

The introduction port 6 a of the far outlet pipe 6 is directed at a predetermined distance H above the spray port 8 a of the particle spray pipe 8. The predetermined distance H is determined by the wind force of the upper air 12a and the diameter of the far outlet pipe 6, but is preferably about 0.5 times the diameter of the pipe 6 (15 cm in this example).

  The far outlet pipe 6 is provided with a bowl-shaped plate 60 having a circular arc cross section at the inlet 6a. The bowl-shaped plate 60 is narrowed toward the introduction port 6a (downward) and is provided so as to spread upward.

The roof plate 61a is formed in a V shape, and in this example, both side portions spread so as to be directed upward by about 30 degrees with respect to the horizontal direction. The angle is not limited as long as the atomized particles 4b can be diffused by being sent obliquely upward (about 10 to 80 degrees with respect to the horizontal direction).

  As shown in the arrow direction 6d, the atomized particles 4b guided from the outlet 6b collide with the roof plate 61a, pass between the roof plate 61a and the horizontal plate 61b, and further obliquely along the roof plate 61a. Guided upward. As a result, the atomized particles 4b descend while being pushed obliquely upward from near the ceiling, so that they are diffused in a very wide area, and the deodorizing, antibacterial, and aroma effects on the indoor environment can be dramatically improved. Further, negative ions can be diffused at a high concentration without decreasing. In addition, a part of this far outlet pipe 6 may extend in the horizontal direction.

  A modification 61 'of the sending means will be described. As shown in FIG. 14, the delivery means 61 'is configured in a trumpet shape that is connected to the outlet 6b and expands in the horizontal direction. Accordingly, the atomized particles 4b led out from the outlet 6b are guided by the trumpet-shaped sending means 61 'and scattered in the horizontal direction. The trumpet shape includes not only a circular shape but also a square shape. The two distant outlet pipes 6 and 6 are provided with delivery means 61 'and 61', respectively, and the diverging portions of the delivery means 61 'and 61' are directed in different directions, so that the fog The particles 4b are diffused uniformly throughout the room. Further, each delivery means 61 ′ is provided with a delivery fan 62 so that the atomized particles 4 b can be delivered to a farther and wider area as shown by the arrow direction in FIG. 14 (b).

The discharge side of the photocatalytic filter 130 is connected to the injection fan 12 via the air supply pipe 131. Accordingly, the purified air is sent to the injection fan 12.

  An air injection pipe 11 extending upward is connected to the injection fan 12. The air injection pipe 11 is provided with a soundproof cover 70 for preventing air noise from the injection fan 12. The soundproof cover 70 is made of, for example, a sound absorbing material made of urethane that covers a wire mesh. A particle spray pipe 8 is connected to the air injection pipe 11 and protrudes upward through the inside thereof. Thereby, the air injection pipe 11 is provided around the outer periphery of the particle spray pipe 8, and the atomized particles 4b and the upper air 12a are injected upward.

  An introduction port for the far outlet pipe 6 is arranged at a predetermined interval from the upper ends of the particle spray pipe 8 and the air injection pipe 11. As will be described in detail later, an attracting cover 65 is provided at this predetermined interval. The far outlet pipe 6 extends in the vertical direction, bends in the middle, and extends in the horizontal direction. The horizontal pipe portion 63 in the horizontal direction of the far outlet pipe 6 extends relatively long. The horizontal pipe part 63 has a plurality of discharge parts 64 connected at substantially equal intervals.

  As shown in FIG. 15B, the discharge portions 64 are provided on both sides of the horizontal pipe portion 63. The discharge part 64 is connected to the horizontal pipe part 63 via the connection pipe 640. Then, the atomized particles 4 a in the far outlet pipe 6 that have been mixed and stirred are discharged downward from the discharge portions 64 through the horizontal pipe portion 63. For example, the atomization particle 4a can be sprayed directly for every seat by arrange | positioning the discharge | release part 64 for every seat, such as a musical hall and a pachinko. Thereby, a deodorizing and aroma effect can be improved significantly. As shown in FIG. 5A, the horizontal pipe portion 63 is gradually narrowed in the flow direction of the atomized particles 4a, and thereby the wind speed of the atomized particles 4a is adjusted to be uniform.

  As shown in FIGS. 16A and 16B, the discharge portion 64 extends downward and has an arcuate bulge portion 64a at the lower end. A large number of holes 64b are provided in the bulging portion 64a. Further, the discharge portion 64 is provided with a wind speed adjusting plate 66 at the upper end. Accordingly, the atomized particles 4 b are introduced from the connecting pipe 640 through the wind speed adjusting plate 66 to the discharge portion 66. As shown in FIG. 16C, the wind speed adjusting plate 66 is a rectangular plate and is provided with a plurality of holes 66a. Depending on the area of the hole 66 a of the wind speed adjusting plate 66, the wind speed of the atomized particles 4 a introduced from the connection pipe 640 to the discharge portion 64 is adjusted to be uniform for each discharge portion 64. And according to the shape of the bulging part 64a, the atomized particle 4b spreads radially, and is sprayed below.

  As shown in FIG. 17, the attracting cover 65 is configured in a cylindrical shape, and is disposed so as to cover a predetermined distance between the air injection pipe 11 and the far outlet pipe 6. The attracting cover 65 is open at the top, closed at the bottom, and has a lower wall 65a. The diameter of the attraction cover 65 is configured to be larger than the diameter of the far outlet pipe 6 so that the outside air 6c can be sufficiently attracted from the opening 65b of the attraction cover 65. The air injection pipe 11 is disposed through the lower wall 65a of the attracting cover 65. Therefore, the outside air 6c is not attracted from other than the opening 65b of the attraction cover 65, and can attract the outside air effectively. Further, in the present embodiment, the particle spray pipe 8 has a nozzle portion 8e that is tapered toward the upper end. By this nozzle portion 8e, the flow of the atomized particles 4b becomes faster and the lift-up action can be increased.
