Mounted.

  The tank 1 is formed in a hollow shape so that a liquid such as water can be stored. Although not shown, a liquid injection port that can be opened and closed by a stopper is provided on the proximal end side of the tank 11. By removing the plug from the liquid injection port, water is introduced into the tank 1 from the opened liquid injection port, and then the liquid injection port is closed with a plug so that the water in the tank 1 can be accommodated and held. It has become.

  The connecting body 11 is provided to guide the water in the tank 1 to the mist generating section 21. Here, the connecting body 13 is provided at the tip of the connecting member 13 with the penetrating member 12 accommodated therein, and the mist generating section 21. And a holding member 14 that holds the desired angle of inclination. The connecting member 13 is formed in a cylindrical shape having a proximal end and a distal end opened, and a liquid absorbing member 15 that sucks up water in the tank 1 and guides it to the penetrating member 12 is provided in the opening on the proximal end side. The permeation member 12 is formed of a porous material such as a sponge, for example, and is disposed inside the coupling body 11 for the purpose of permeating water in the tank 1 to the mist generating unit 21.

  The holding member 14 is disposed in the base 16 attached to the tip of the connecting member 13, the lid 17 covering the tip opening of the base 16, the holding member 14, the penetrating member 12, the mist generating unit 21, and the like. And a liquid absorbing member 18 interposed therebetween. The base 16 is formed with a cylindrical joint portion 19 protruding from the base end side, and the joint portion 19 is fitted in a watertight state in a gap formed between the distal end opening of the connecting member 13 and the penetrating member 12. . Further, the lid body 17 is mounted from the distal end side of the base 16 so as to press the liquid absorbing member 18 against the distal end surface of the penetrating member 12. The lid 17 has a cylindrical receiving portion 20 that conforms to the outer shape of the mist generating portion 21 in order to hold the mist generating portion 21 at a desired angle. Each mist generating portion 21 is inserted into the corresponding receiving portion 20 until the base end surface of the mist generating portion 21 comes into contact with the liquid absorbing member 18, and water that has reached the permeation member 12 via the liquid absorbing member 18 is generated. Guided to part 21. The mist generator shown in FIGS. 1 and 2 includes three mist generators 21, but the number thereof is not limited, and the mist generators 21 are erected in a vertical direction rather than in an oblique direction. May be.

  The holding member 14 is provided as an application electrode for applying a voltage to the water sucked up by the mist generating part 21 in addition to attaching and holding the plurality of mist generating parts 21 at equal intervals. Although not shown here, the mist generating device includes a grounded counter electrode facing the tip 24 of the mist generating unit 21 and a voltage applying unit that applies a high voltage between the holding member 14 and the counter electrode that are application electrodes. And each.

  3 to 5 each show an example of a preferred mist generating unit 21. In each of these drawings, the mist generating portion 21 is formed by compressing a cylindrical shape by bundling fine polyester, carbon fiber, etc., and causing the liquid water along the axial direction (vertical direction) due to a pressure difference or a capillary phenomenon. It is configured to suck up from the proximal end side to the distal end side. Further, here, a mist column 22 as a body having a smooth outer surface without irregularities, and a distal end that is located at the distal end of the mist column 22 and has an uneven roughened portion 23 formed on the outer peripheral side surface in the radial direction thereof. The mist generating unit 21 is configured by the unit 24. The overall shape of the mist generating portion 21 is considered to be optimal in the form of a cylinder in consideration of the suction of water in the tank 1 due to capillarity and the like, and the transportation of water to the tip portion 24, etc. It may be a columnar shape.

  The distal end portion 24 of the mist generating portion 21 that is a substantial mist generating portion may have an outer surface having an arbitrary shape such as a spherical shape, an arc shape, or a horizontal plane shape. For example, the mist generating part 21 shown in FIGS. 2 and 3 has an outer surface 24 (particularly an end face 26) of the tip part 24 formed in a horizontal plane perpendicular to the axial direction, and the mist generating part 21 shown in FIG. An outer surface 24A (a surface including the end surface 26 and side surfaces) of the portion 24 is formed in a rounded sphere (semicircle). FIG. 4 also shows a case where the outer surface 24A ′ of the tip 24 is formed in a circular arc shape that is flatter than a spherical shape.

  The aforementioned roughened portion 23 is provided with a plurality of protrusions (pointed portions) 27 whose end surfaces are preferably formed in a pointed shape and have fine corners at the tips. In the example shown in FIG. 2, the mist column 22 is rotated around the vertical axis, and a cutting tool (not shown) such as a cutter is not moved in the vertical direction. By digging, a ring-shaped protrusion 27 is formed. In the example shown in FIGS. 3 and 4, similarly, the mist column 22 is rotated around the vertical axis, and the cutting tool is moved at a constant speed in the vertical direction, and a groove is dug on the outer peripheral side surface of the tip portion 24 with the cutting tool. As a result, a spiral projection 27 is formed. There may be a plurality of spiral peaks. The plurality of protrusions 27 shown in each of these drawings may be connected and formed in a linear shape, or may be formed in an indefinite interval or a predetermined interval, and may be dug in the groove shape of the roughened portion 23. It is partially formed except for the inserted portion.

  In this way, the roughened portion 23 of the mist generating portion 21 is formed only on the side surface, not the end surface 26 of the tip portion 24, and the projections 27 formed on the roughened portion 23 are formed on the upper portion of the tip portion 24. A spherical outer surface 24A and an arc-shaped outer surface 24A ′ are formed in an area corresponding to the width direction W of the mountain or more (see FIG. 5).

  The dimensions of each part of the preferred mist generating part 21 are as follows. As shown in FIG. 2, the outer diameter D of the mist column 22 is about 0.5 mm to 10 mm, the length L1 of the mist generating portion 21 including the distal end portion 24 is about 5 mm to 100 mm, and the length L2 of the distal end portion 24 is 2. About 30 mm. Further, as described above, the protrusion 27 formed on the outer peripheral side surface of the distal end portion 24 is formed by digging a groove with a cutter or the like, and the depth (height of the protrusion 27) T of the groove is 0. It is formed to be about 01 mm to 2 mm. These dimensional ranges are values that are set so that the water in contact with the mist column 22 is sucked up by capillary action and smoothly led to the respective protrusions 27 of the roughened portion 23 uniformly.

  In the example shown in FIGS. 3 and 4, the outer diameter of the roughened portion 23 has a size equivalent to the outer diameter D of the mist column 22 that is a part other than the roughened portion 23. In the example shown in FIG. 5, the outer diameter of the roughened portion 23 is smaller than the outer diameter D of the mist column 22 that is a part other than the roughened portion 23. In any case, by making the outer diameter of the roughened portion 23 smaller than the outer diameter D of the mist column 22, the mist generating portion 21 can be made compact.

  Next, the effect | action is demonstrated about the said structure. When water, which is liquid, is stored in the tank 1 and the mist generating unit 21 and the tank 1 are connected by the connecting body 11, the liquid absorption member 15 immersed in the water in the tank 1 is connected to the inside of the connecting member 13. Water penetrates into the osmotic member 12 and is guided to the proximal end of the mist generating part 21 having a capillary structure via another liquid absorbing member 18 that contacts the osmotic member 12. In the mist generating part 21, the water that has contacted the mist column 22 is sucked from the proximal end side toward the distal end part 24 along the axial direction of the mist generating part 21, and is a rough surface formed on the outer peripheral side surface of the distal end part 24. They are respectively guided to the protrusions 27 of the conversion part 23.

  In this state, when the counter electrode (not shown) is grounded and a high voltage is applied to the holding member 14 of the coupling body 11 provided as the application electrode, the tip portion is drawn when the mist generating part 21 sucks water by capillary action. Since the protrusion 27 of the roughened portion 23 formed on the outer peripheral side surface of 24 functions as a substantial electrode on the application electrode side, the water guided to the protrusion 27 causes Rayleigh splitting and electrostatic atomization, Mist (charged particulate water) diffuses into the atmosphere.

  Since the projection 27 partially provided on the roughened portion 23 has a pointed end surface and is formed in a plurality of lines or dots, the end surface is not a pointed shape but rather than a single tip. The water led to 27 can be generated in large quantities as fine mist. In addition, since a plurality of projections 27 are provided as the convex portions of the roughened portion 23, even if one of the projections 27 is worn, the mist of a small size is continued with water guided to the other projections 27. Can be generated.

  Further, as shown in FIGS. 3 to 5, the protrusion 27 is formed in a ring shape or a spiral shape around the radial direction of the mist generating portion 21. Thus, the processus | protrusion 27 is connected and formed in a row, and the several processus | protrusion 27 with strong intensity | strength can be formed. Further, by applying a high voltage to the water guided to each protrusion 27 to form an electrostatic atomization, it is possible to uniformly generate a mist having a fine size from the mist generating unit 21.

  As described above, in this embodiment, the distal end portion 24 has an arbitrary shape such as a spherical shape, an arc shape, or a horizontal plane shape, and includes a columnar mist generating portion 21 that sucks up water as a liquid by a pressure difference or a capillary phenomenon. An uneven surface roughened portion 23 is formed on the outer surface of the tip 24 of the mist generating portion 21.

  If it does in this way, it will become the composition that mist generate | occur | produces from the convex part of the several uneven | corrugated front-end | tip of the roughened surface by making the outer side surface of the front-end | tip part 24 of the mist generating part 21 into a roughened shape. The amount of mist generated from the front end portion 24 increases. In addition, since the roughened portion 23 is provided with a plurality of convex portions, it is possible to continuously generate mist of a predetermined size from the other protrusions 27 even if one of the convex portions is consumed. Therefore, in this embodiment, it is possible to provide a mist generating device capable of increasing the amount of mist generated and continuously generating mist of a predetermined size.

  In particular, the roughened portion 23 of the present embodiment is partially provided with protrusions 27 as pointed portions formed in a plurality of points as the aforementioned convex portions.

  Thus, by providing the plurality of protrusions 27 partially on the roughened portion 23 of the mist generating part 21, it is possible to generate a large amount of fine mist from the protrusions 27.

  In particular, the protrusion 27 of the present embodiment is formed in a ring shape or a spiral shape around the outer surface of the mist generating portion 21.

  In this case, a plurality of projections 27 having high strength can be formed by forming the projections 27 in a continuous manner around the outer surface of the mist generating portion 21.

  Furthermore, the outer diameter of the roughened portion 23 in the present embodiment has a dimension that is equal to or smaller than the outer diameter D of the mist column 22 that is a portion other than the roughened portion of the mist generating portion 21. .

  In this way, the outer diameter of the roughened portion 23 is not larger than the outer diameter D of the mist column 22, and the outer diameter as the mist generating portion 21 is increased by providing the roughened portion 23. Can prevent the negative effects.

  In addition, this invention is not limited to the said Example, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the structure which permeate | transmits the water in the tank 1 to the mist generating part 21 is not limited to what was shown in FIG.1 and FIG.2. Further, the shape of the tip of the convex portion of the roughened portion 23 is preferably formed in a cusp shape, but a part or the whole of the convex portion may be formed in a shape other than the cusp shape (for example, an arc shape). .
