The main body 2 includes a housing 21, a tank 22 inside the housing 21, and a generation unit 23.
The housing 21 may have an appropriate shape, and in the present embodiment, it has a hexahedral shape. The housing 21 is made of, for example, resin. The upper surface 211 of the housing 21 has an insertion port 212 and a water injection port 213. The insertion port 212 is arranged at, for example, the central portion of the upper surface 211. The water injection port 213 is covered with a lid (not shown). The lid is opened when the water inlet 213 is used.

The tank 22 is formed inside the housing 21 and stores hypochlorite water poured from the water injection port 213. The tank 22 may be separated from the housing 21 and can be taken in and out of the housing 21. The hypochlorous acid water may be electrolyzed water generated by electrolysis or hypochlorous acid-dissolved water in which the pH is adjusted by dissolving sodium hypochlorite. The electrolyzed water may be an acidic electrolyzed water having a pH of 2 to 6.5, a neutral electrolyzed water having a pH of 6.5 to 8, or an acidic or neutral electrolyzed water diluted with tap water. Acidic electrolyzed water can obtain the same bactericidal effect at a lower chlorine concentration than sodium hypochlorite water. The chlorine concentration of the acidic electrolyzed water is preferably 5 to 50 ppm, and particularly preferably 10 to 30 ppm in order to obtain sufficient safety and bactericidal activity.

Hypochlorite water is supplied to the generation unit 23 from the tank 22. The generation unit 23 generates a mist of hypochlorite water. The mist is a mist of fine droplets. The mist is sent to the pipe 3. The generation unit 23 may have an appropriate configuration, and for example, mist can be generated by an ultrasonic method. As an example of the ultrasonic type generation unit 23, the generation unit 23 includes a generation tube 231, an oscillator 232, a fan 233, and a primary orifice 234.

The generation pipe 231 extends from the bottom surface in the tank 22 to the upper surface, and opens at the upper surface 211 of the housing 21.

FIG. 2 is a cross-sectional view of the pipe 3. FIG. 3 is a side view of the pipe 3.
The pipe 3 may be made of an appropriate material, and is made of resin in this embodiment. The pipe 3 includes a first pipe 31 and two second pipes 32.
The first pipe 31 is connected to the main body 2 and extends upward, and mist is sent from the main body 2. There is a secondary orifice 4 in the first pipe 31.

The first pipe 31 has a stepped cylindrical shape and includes a large diameter portion 311 and a small diameter portion 312.
The large diameter portion 311 is connected to each second pipe 32 and is located outside the main body 2.
The small diameter portion 312 is slightly reduced in diameter from the large diameter portion 311, and at least a part thereof is inserted into the insertion port 212 and is located in the main body 2. In the present embodiment, the small diameter portion 312 is completely inserted into the insertion port 212. The pipe 3 may be fixed to the main body 2 by fitting the small diameter portion 312 into the insertion port 212. A fixing mechanism for fixing the pipe 3 to the main body 2 may be provided.

Inside the first pipe 31, a stepped portion 313 whose upper side expands is formed along the circumferential direction by the connecting portion between the large diameter portion 311 and the small diameter portion 312. The outer edge of the secondary orifice 4 is supported by the step portion 313.
The second pipe 32 includes a tubular portion 323 and a lid 8 that closes the tip opening 324 of the tubular portion 323. The tubular portion 323 is formed by assembling the upper split body 7 and the lower split body 6. The upper split body 7 and the lower split body 6 have a shape in which the tubular portion 323 is roughly divided into upper and lower parts.

FIG. 4 is a perspective view of the secondary orifice 4.
The secondary orifice 4 has a dome shape. In a plan view, there is a mist outlet 41 on the center side of the secondary orifice 4. Further, as an example of the configuration relating to the drain of the secondary orifice 4, there is a drain groove 42 on the outer edge.

Here, the droplets in the mist are enlarged by repeatedly colliding with each other. When a droplet having a large particle size falls or adheres to the inner wall surface of the second pipe 32, it easily flows on the inner wall surface, which causes the droplet to drip from the ejection port 5 of the second pipe 32.

The secondary orifice 4 is made of resin as an example, and micro-concavities and convexities are formed over the inner wall surface by embossing, and the wettability of the inner wall surface is enhanced. As a result, droplets having a large particle size in the mist passing through the secondary orifice 4 are likely to adhere to the inner wall surface of the secondary orifice 4, which leads to suppression of droplets from the ejection port 5. The embossing on the secondary orifice 4 and the second pipe 32, which will be described later, is a process of transferring minute irregularities from the mold to the resin during injection molding of the resin. The next orifice 4 and the second pipe 32 may be directly etched, sandblasted, or laser-processed.

The surface roughness Ra of the inner wall surface of the secondary orifice 4 can be set to, for example, 20 μm. The surface roughness Ra of the inner wall surface of the secondary orifice 4 is preferably 1 mm or less. As a method for measuring the surface roughness Ra, for example, a non-contact measuring method according to the ISO25178 standard can be applied. The inner wall surface of the secondary orifice 4 may not be textured.

The secondary orifice 4 includes a cylindrical portion 43 and a dome wall portion 44.
The outer shape of the cylindrical portion 43 is substantially the same as the inner diameter of the large diameter portion 311.

The dome wall portion 44 is connected to the upper end of the cylindrical portion 43 and has a dome shape. The dome shape can be rephrased as a squeezed tip. At the top of the dome wall 44, there is an exit 41. The outlet 41 is a circular hole passing through the central axis of the secondary orifice 4, which is wider than the hole 235 of the primary orifice 234 and shorter in the vertical direction. The secondary orifice 4 adjusts the flow rate and flow velocity of the mist, and ejects the mist so as to spread horizontally from the primary orifice 234, so that the mist is smoothly sent to the two second pipes 32 extending to the left and right. be able to.

In the present embodiment, the dome-shaped secondary orifice 4 can block the passage of droplets having a high collision probability located near the peripheral edge of the secondary orifice 4 and droplets having a large particle size, and can be dropped from the ejection port 5. Leads to suppression of. In addition, a plurality of outlets 41 may be arranged around the central axis of the dome wall portion 44 in a plan view.

A guide plate 441 is erected along the radial direction on the outer edge side of the dome wall portion 44. A plurality of guide plates 441 are spaced apart from each other in the circumferential direction, and extend linearly to the outer edge of the dome wall portion 44. When the secondary orifice 4 is inserted into the large diameter portion 311 of the first pipe 31, the guide plate 441 contacts the inner wall surface of the large diameter portion 311 to prevent the secondary orifice 4 from tilting.

A plurality of drain grooves 42 are spaced apart from each other in the circumferential direction of the secondary orifice 4. The drain groove 42 extends from the outer edge portion of the dome wall portion 44 to the lower end of the cylindrical portion 43. Mist having a large particle size may become droplets on the inner wall surface of the large diameter portion 311 and the droplets may flow downward along the inner wall surface of the large diameter portion 311. Further, the droplets flowing down from the second pipe 32 also flow downward along the inner wall surface of the large diameter portion 311. The drain groove 42 forms a drain passage between the inner wall surface and the inner wall surface of the large-diameter portion 311 for the droplets flowing downward to pass downward.

FIG. 5A is a diagram showing another example of the secondary orifice.
A cylindrical portion 43A is connected to the upper end of the dome wall portion 44A of the secondary orifice 4A. There is a drain groove 42A on the outer edge of the dome wall portion 44A. There are a plurality of drain grooves 42A at intervals in the circumferential direction. The upper end of the cylindrical portion 43A serves as the mist outlet 41A.

FIG. 5B is a diagram showing another example of the secondary orifice.
The dome wall portion 44B is connected to the upper end of the cylindrical portion 43B of the secondary orifice 4B. At the top of the dome wall 44B, there is a mist outlet 41B. In the dome wall portion 44B, there is a drain hole 42B radially outside the outlet 41B. There are a plurality of drain holes 42B at intervals in the circumferential direction. The drain hole 42B allows droplets flowing downward to pass downward along the inner wall surface of the large diameter portion 311 of the first pipe 31. In the secondary orifices 4 and 4A, the drain hole 42B may be applied instead of the drain grooves 42 and 42A, or the drain hole 42B may be applied in addition to the drain grooves 42 and 42A.

Returning to FIG. 2, the droplet that has passed downward through the drain groove 42 flows downward along the inner wall surface of the small diameter portion 312, and falls into the generation pipe 231 from the central hole 235 of the primary orifice 234. On the other hand, the mist ejected upward from the secondary orifice 4 advances into each of the second pipes 32 via the upper part of the first pipe 31.

Each of the second pipes 32 branches from the upper end of the first pipe 31 and extends upward and laterally, respectively. Each second pipe 32 has a cylindrical shape, and in the present embodiment, the second pipe 32 extends so as to be in a straight line to the left and right when viewed from above.

In each of the second pipes 32, minute irregularities are formed over the inner wall surface by embossing, and the wettability of the inner wall surface is enhanced. In addition, the minute irregularities play a role of collecting the droplets in the mist having a large particle size into large droplets. As a result, droplets having a large particle size in the mist passing through the second pipe 32 are likely to adhere to the inner wall surface of the second pipe 32. Therefore, in the present embodiment, it is possible to suppress the adhesion of droplets due to mist to the inner wall surface around the ejection port 5, and it is possible to suppress the droplets from the ejection port 5. Further, in the present embodiment, it is possible to suppress the spraying of droplets having a large particle size in the mist. The surface roughness Ra of the inner wall surface of the second pipe 32 is preferably 1 mm or less, more preferably 10 to 50 μm.

The second pipe 32 extends to the left and right from the left and right ends of the main body 2 (see FIG. 1). The axis C1 of the second pipe 32 is inclined upward with respect to the horizontal plane. The inclination θ1 of the axis C1 is, for example, 15 degrees. In the present embodiment, by making the inclination θ1 of the axis C1 smaller than 45 degrees, it is possible to achieve a good balance of spraying mist over a wide area on the foot side while suppressing the height of the second pipe 32. ..

In the present embodiment, since the second pipe 32 extends upward and to the side of the main body 2, the droplets captured on the inner wall surface of the second pipe 32 can flow downward along the inner wall surface, and the spout 5 It is possible to prevent the droplets from falling from the wall.

The two second pipes 32 may not extend so as to be in a straight line when viewed from above, and may be arranged so that the axes C1 of the respective second pipes 32 intersect. There may be three or more second pipes 32. The inclination θ1, the cross-sectional shape, and the length of the second pipe 32 may be in an appropriate manner.

On the tip end side and the lower side of each second pipe 32, there is an ejection port 5 for ejecting mist that has moved in the second pipe 32. The tip side refers to a region between the center and the tip of the second pipe 32 in the axial direction.
The spout 5 is formed to include an inner opening 51, an outer opening 52, and a guide surface 53.
The inner opening 51 is formed inside the second pipe 32 by the upper end portion of the annular wall portion 54 (see also FIG. 7) that is tapered toward the inside of the second pipe 32. The inner opening 51 is, for example, a perfect circle. The cross-sectional shape of the annular wall portion 54 may be linear or curved.
The guide surface 53 is annular and includes the outer wall surface of the annular wall portion 54 exposed to the outside of the atomizer 1 and expands from the inner opening 51 to reach the outer opening 52.

FIG. 6 is a diagram showing a spout 5 seen from below.
The outer opening 52 is formed on the outer wall surface of the second pipe 32 in a longitudinal shape along the axial direction of the second pipe 32. The inner opening 51 is located inside the outer opening 52. In the outer opening 52, the end edge Te on the distal end side (right side in FIG. 6) in the axial direction is farther from the inner opening 51 than the edge Be on the proximal end side (left side in FIG. 6). In other words, the distance LTE between the end edge Te on the distal end side and the center C2 of the inner opening 51 is longer than the distance LBe between the edge Be on the proximal end side and the center C2 of the inner opening 51.

With the above configuration of the spout 5, the atomizer 1 can satisfactorily spray the mist downward and in the left-right direction. Therefore, the nebulizer 1 can inactivate viruses and the like in the space on the foot side over a wide range of surroundings.
Further, in the present embodiment, since the annular wall portion 54 of the ejection port 5 rises toward the inside of the second pipe 32, the droplets captured on the inner wall surface of the second piping 32 are less likely to enter the ejection port 5. ..

As described above, the pipe 3D is different from the pipe 3 in that the second pipe 32D does not have a lid, and the other configurations are the same as those of the pipe 3. For example, minute irregularities are formed over the inner wall surface of the second pipe 32D by embossing.

By adopting the above configuration, in the present embodiment, the mist emitted from the ejection port 5D can be ejected diagonally upward (in other words, toward the side) as compared with the first and second embodiments. The mist can be sprayed on the floor to expand the area.

(Fourth Embodiment)
In the fourth embodiment of FIGS. 13 to 15, the number of parts can be reduced by integrating each part, and the lid 8E and the upper split body 7E can be removed, so that the inside of the second pipe 32E can be easily removed. The cleaning effect can be achieved at the same time.

Specifically, FIG. 13 is a perspective view of the lower split body 6E and the first pipe 31E of the fourth embodiment.
The lower split body 6E has the same configuration as the lower split body 6 of FIG. 7, and the elements 61E to 64E of the lower split body 6E correspond to the elements 61 to 64 of the lower split body 6 of FIG. .. The lower split body 6E constitutes a second pipe 32E that is flatter than the second pipe 32 in FIG. 2, and is flatter than the lower split body 6 in FIG. 7. The arcuate portion 61E has a smaller curvature than the arcuate portion 61 in FIG. 7. On the tip side of the arcuate portion 61E in the axial direction, there is an insertion port 65E so as to straddle the ejection port 5E. The pair of flat plate portions 62E facing each other in the front-rear direction are provided with a plurality of holes 91E at intervals in the left-right direction. A fixing mechanism 9E for fixing the lower split body 6E and the upper split body 7E (FIG. 14) is configured including the hole 91E.

FIG. 14 is a perspective view of the upper split body 7E of the fourth embodiment. Similarly, the upper split body 7E has the same configuration as the upper split body 7 of FIG. 8, and the elements 71E to 74E correspond to the elements 71 to 74 of the upper split body 7 of FIG. The arcuate portion 71E has a smaller curvature than the arcuate portion 71 in FIG. There is an insertion port 75E on the tip side of the arcuate portion 71E in the axial direction. The pair of upper guide portions 73E facing each other in the front-rear direction are provided with claws 92E extending downward (upper in FIG. 14) beyond the lower end (upper end in FIG. 14) of the upper guide portion 73E. A plurality of claws 92E are provided at intervals in the left-right direction. The fixing mechanism 9E is configured including the claw 92E. The tip of the claw 92E is provided with a protrusion 921E protruding outward in the front-rear direction. By inserting each protrusion 921E into each hole 91E of the lower split body 6E, the lower split body 6E and the upper split body 7E are fixed.

FIG. 15 is a perspective view of the lid 8E of the fourth embodiment.
The lid 8E has the same configuration as the lid 8 of FIG. 9, and the elements 81E to 83E correspond to the elements 81 to 83 of FIG. Claws 84E are provided at the upper and lower portions of the insertion portion 82E. The lid 8E is fitted to the assembled lower split body 6E and upper split body 7E. At this time, the claw 84E is inserted into the insertion ports 65E and 75E of the divided bodies 6E and 7E to fix the lid 8E.

The present invention can be implemented in embodiments without departing from its characteristics. The embodiments, modifications, and effects are merely exemplary and should not be construed as limiting the invention. The features and structures of embodiments and variants can be added and combined in various ways to obtain alternative configurations.
