  Next, a mist spray switch (not shown) of the sprayer 100 is operated. Thereby, the spraying device control unit operates the spraying unit 70, and the spraying unit 70 mists the sprayed liquid absorbed from the liquid storage tank 80 and sprays it into the space from the spraying port 72. Further, by operating an accompanying facility operation switch (not shown) for the accompanying facility 10, the accompanying facility 10 of the sprayer 100 performs a predetermined operation independently of the spray unit 70.

  Next, the spraying apparatus according to the present invention will be described in more detail with reference to FIG. 4 (a) is a front view of the spray unit 70 constituting the spray device according to the present invention, FIG. 4 (b) is a side view of the spray unit 70, and FIG. 4 (c) is a cross-sectional view of the spray device according to the present invention. It is.

  The spray unit 70 of the spray device according to the present invention is mainly composed of a mist generating means 74 and a spray liquid supply means, and there are many fine through holes 79 of about 5 μm at predetermined positions of the mist generating means 74. The formed vibrator 73 is installed. The surface side of the vibrator 73 is exposed from the mist outlet 75, and the third liquid 71c is in contact with the back surface side of the vibrator 73 at a predetermined contact pressure. Further, one end of a wiring 78 is connected to the vibrator 73, and the other end of the wiring 78 is connected to a spraying device control unit. The vibrator 73 vibrates at high speed at a predetermined frequency when an operation signal from the spray device controller is input via the wiring 78.

  The spray liquid supply means of the spray unit 70 is mainly composed of a first retaining liquid 71a, a second retaining liquid 71b, a third retaining liquid 71c, and a casing 76 for housing them. And the spraying part 70 is installed in the predetermined position of the tank unit 40 so that the 1st holding | maintenance liquid 71a accommodating part of the casing 76 may be immersed in the spray liquid 5 in the liquid storage tank 80 which comprises a spraying apparatus. In addition, an opening 76 a is formed in a portion of the casing 76 that accommodates the first retaining liquid 71 a, and a part of the first retaining liquid 71 a is exposed through this opening 76 a and is immersed in the spray liquid 5. The upper end of the first retained liquid 71a is in contact with the bottom surface of the substantially cylindrical second retained liquid having a predetermined inner diameter and outer diameter, and one end of the third retained liquid 71c is on the outer peripheral surface of the second retained liquid. The contact is made at a predetermined contact pressure. Further, the other end of the third retentive liquid 71 c is in contact with the back surface side of the vibrator 73 constituting the mist generating means 74 with a predetermined contact pressure.

  The first retaining liquid 71a and the third retaining liquid 71c are composed of fiber bundles of synthetic resin such as polypropylene, acrylic, polyester, etc., and the second retaining liquid 71b is hydrophilic and moisturizing such as polyvinyl alcohol. Consists of synthetic resin.

  The first retentive liquid 71a absorbs the spray liquid 5 in the liquid storage tank 80 by the capillary phenomenon of the first retentive liquid 71a and supplies it to the second retentive liquid 71b in contact with the upper end of the first retentive liquid 71a. The second retentive liquid 71b absorbs the spray liquid 5 supplied from the first retentive liquid 71a and supplies it to the third retentive liquid 71c in contact with the outer peripheral surface of the second retentive liquid 71b. The third retentive liquid 71c supplies the spray liquid 5 supplied from the second retentive liquid 71b to the vibrator 73 by the capillary action of the third retentive liquid 71c. Then, the vibrator 73 vibrates at high speed, so that the spray liquid 5 supplied from the third liquid 71 c is misted by the fine through-hole 79 provided in the vibrator 73 and discharged from the mist outlet 75. The mist discharged from the mist outlet 75 is sprayed into the space via the spray port 72 of the tank unit 40.

  At this time, the amount of mist ejected depends on the contact pressure between the vibrator 73 and the third retaining liquid 71c. Since the third retentive liquid 71c is not bent and is substantially linear, the contact pressure between the vibrator 73 and the third retentive liquid 71c is the contact pressure between the third retentive liquid 71c and the second retentive liquid 71b. Is almost equivalent to The contact pressure between the third retained liquid 71c and the second retained liquid 71b is determined by the length of the third retained liquid 71c and the restoring force of the second retained liquid 71b, and the length of the third retained liquid 71c is constant. The contact pressure is determined by the restoring force of the second holding liquid 71b. The restoring force of the second retentive liquid 71b can be adjusted by the thickness of the second retentive liquid 71b, that is, the inner diameter of the second retentive liquid 71b. That is, if the inner diameter of the second retained liquid 71b is increased and the thickness of the second retained liquid 71b is decreased, the restoring force of the second retained liquid 71b is decreased, and the contact pressure between the vibrator 73 and the third retained liquid 71c is decreased. As a result, the amount of mist ejected decreases. Conversely, if the inner diameter of the second retentive liquid 71b is reduced and the thickness of the second retentive liquid 71b is increased, the restoring force of the second retentive liquid 71b increases, and the contact pressure between the vibrator 73 and the third retentive liquid 71c is It rises and the amount of mist ejection increases. Therefore, the amount of mist ejected can be made appropriate by optimizing the inner diameter of the second retaining liquid 71b. Further, as described above, since the third retentive liquid 71c is substantially linear, the contact pressure between the vibrator 73 and the third retentive liquid 71c does not vary greatly, and the mist spray can be stably performed with an optimal ejection amount. It can be performed.

  The central axis of the inner diameter of the second liquid retaining liquid 71b may be shifted by a predetermined distance from the central axis of the outer diameter, and the thickness of the second liquid retaining liquid 71b may be different at the outer peripheral surface position. According to this configuration, by rotating the second retentive liquid 71b in the axial direction, the thickness of the second retentive liquid 71b at the contact portion with the third retentive liquid 71c changes, and the amount of mist ejected can be varied. it can.

  From the above, according to the spray device according to the present invention, the second retentive liquid 71b is substantially cylindrical, and the contact pressure between the mist generating means 74 and the third retentive liquid 71c is adjusted by the thickness of the second retentive liquid 71b. . Therefore, if the inner diameter of the second retentive liquid 71b is optimized, the amount of mist ejected can be made appropriate.

  In addition, according to the spray device according to the present invention, the liquid retaining liquid in the spray liquid supplying means is constituted by the first liquid retaining liquid 71a, the second liquid retaining liquid 71b, and the third liquid retaining liquid 71c, so Even when the spray liquid is absorbed from the tank and the mist is sprayed in a substantially horizontal direction, the third retaining liquid 71c in contact with the mist generating means 74 can be made substantially linear. Thereby, the dispersion | variation in the contact pressure of the mist production | generation means 74 and the 3rd holding | maintenance liquid 71c reduces, and can spray mist stably with a predetermined ejection amount.

  Furthermore, by configuring the retained liquid with the first retained liquid 71a, the second retained liquid 71b, and the third retained liquid 71c, the internal structure and design freedom of the sprayer 100 can be improved.

  In addition, the first retentive liquid 71a and the second retentive liquid 71b may be formed integrally, and the present invention can be modified and implemented without departing from the gist of the present invention.
