The present invention relates to a disinfecting mist spraying device. More specifically, the present invention relates to a sterilization mist spraying device that ejects a sterilization mist, which is a mist of a sterilization agent, to a person to sterilize viruses and the like attached to the person's clothes and the whole body.

In recent years, with the epidemic of infectious diseases caused by viruses such as the new coronavirus infectious disease (COVID-19), it is necessary to disinfect clothes and the whole body to remove viruses etc. as a preventive measure against these threats. sex is required.

In order to satisfy this need, for example, a device has been proposed in which a plurality of spraying portions are provided on a pillar-shaped or gate-shaped device to spray an antibacterial agent in the form of a mist.

As a conventional device for spraying these antibacterial agents, there is one disclosed in Patent Document 1.

However, in the technique described in Patent Literature 1, it is necessary to guide the floating antibacterial agent in the form of a mist to the spray hole by means of a guide pipe or a guide tube and spray it. The antibacterial agent in the form of a mist is unstable and adheres to the inner wall of the guide pipe or tube as droplets as it passes through. And if there are droplets on the inner wall, the antibacterial agent in the form of a mist is more likely to adhere. As a result, the amount of mist-like antibacterial agent discharged from the spray holes is greatly reduced compared to the generated amount, which is inconvenient. Of course, by increasing the amount of the antibacterial agent in the form of a mist, it is possible to increase the amount of the antibacterial agent in the form of a mist that is discharged from the spray holes, but this has the disadvantage of being very inefficient. rice field.

Further, in the technique described in Patent Document 2, it is necessary to atomize the liquid supplied by the spray nozzle portion into mist. Compared to the case where a large amount of mist is generated and sprayed, the atomization at the spray nozzle section has the disadvantage that it is difficult to spray a large amount and the amount to be sprayed is limited.

A drainage pipe 47 protrudes from the lower surface of the bottom of the sanitizing liquid storage tank 41, and a drainage tube 48 is attached thereto.
As shown in FIG. 3, a sterilization lamp 80 for sterilizing the liquid stored in the sterilizing liquid storage tank 41 is provided on the left side of the back surface of the top plate of the sterilizing liquid storage tank 41 .

As shown in FIGS. 2 and 3, the sterilization mist holding cylinder 50 has a sterilization mist holding cylinder main body 51 formed in a square tube shape from a resin plate, and a sterilization mist holding cylinder lid 52 at the upper end that can be attached and detached. It is freely closed, the lower end is open, and it is directly connected to the sterilization mist generator 40. - 特許庁In addition, a plurality of holes are formed in the side wall on the front side of the sterilization mist holding cylinder main body 51, and approximately cylindrical sterilization mist ejection nozzles 53, 53, 53 formed of a flexible material such as rubber, 53 is fixed. Each sterilization mist ejection nozzle 53 is connected so as to be fitted into the sterilization mist ejection port 20 .

As shown in FIGS. 2 and 3, the pump 60 has a pump body 61 and a liquid suction tube 62 and a liquid injection tube 63 connected to the pump body 61 .
As shown in FIGS. 2 and 3, the sterilization liquid tank 70 has a sterilization liquid tank body 71 that stores the sterilization liquid S, and the top surface of the sterilization liquid tank body 71 is provided with an injection tube 63 and A disinfectant tank opening 72 is provided into which the drain tube 48 is inserted.

Now, the function of each part of the sterilization mist spraying device 1 will be described with reference to FIG. First, how the sterilization mist M is ejected will be described.
As shown in FIG. 3, when the ultrasonic vibrator 45 is vibrated, the sterilization liquid S becomes large bubbles of the sterilization mist M, and the sterilization mist M floats near the surface of the sterilization liquid S. As shown in FIG. Further, when the blower fan 43 is rotated, the wind generated by the blower fan 43 is initially a spiral turbulent flow. It is hit on the liquid surface of the fungus liquid S.

As shown in FIG. 3, the air flow from the blower fan 43 sweeps and moves the sterilization mist M floating near the liquid surface of the sterilization liquid S, and becomes the flow of the sterilization mist M. , flows into the sterilization mist holding cylinder 50 . The sterilization mist M that has flowed into the sterilization mist holding cylinder 50 is closed at the top by the sterilization mist holding cylinder lid 52, and its volume is limited. , 53, 53 from the sterilization mist outlets 20, 20, 20, 20.

Next, how the sterilizing liquid S is supplied to the sterilizing mist generator 40 will be described.
As shown in FIG. 3 , the sterilizing liquid S is stored in the sterilizing liquid tank 70 , sucked up by the pump 60 and supplied to the sterilizing mist generator 40 . That is, the sterilizing liquid S is sucked up by the liquid suction tube 62 having a suction port at the bottom of the sterilizing liquid tank 70 , pressurized by the pump body 61 , and injected into the liquid injection tube 63 . The liquid injection tube 63 passes through the liquid injection tube holding pipe 46 and enters the sterilization liquid storage tank 41, and is injected from the liquid injection port of the liquid injection tube 63 on the left side thereof. The injected sterilizing liquid S becomes sterilizing mist M by the ultrasonic oscillator 45, and the remaining sterilizing liquid S moves to the right side of the sterilizing liquid storage tank 41 and spills into the drainage pipe 47 and is sucked. and returns to the sterilization liquid tank 70 via the drainage tube 48 .

The operation of the pump 60 will now be described.
As shown in FIG. 3, when the main power source (not shown) of the sterilizing mist spraying device 1 is turned on, the pump 60 operates for a predetermined time to continue supplying the sterilizing liquid S to the sterilizing liquid storage tank 41 . This is because the sterilizing liquid S in the sterilizing liquid storage tank 41 is made to fall down from the drain pipe 47 so that the height of the liquid surface is maintained at the height of the upper end of the drain pipe 47 in advance. Then, when the sterilization mist M is ejected, the pump 60 operates to supply an amount of the sterilization liquid S larger than the amount of the sterilization mist M to the sterilization liquid storage tank 41 . This is to maintain the height of the liquid surface and to circulate the sterilizing liquid S in the sterilizing liquid storage tank 41 and the sterilizing liquid S in the sterilizing liquid tank 70 .

As shown in FIG. 3, a sterilization lamp 80 is provided at the upper left end of the sterilization liquid storage tank 41, and since the sterilization liquid S is circulated, sterilization is continuously performed by the sterilization lamp 80. FIG. This is to prevent the generation of bacteria in the sterilization solution S that cannot be removed with the sterilization solution S. The position of the sterilization lamp 80 may be provided in the central portion of the sterilizing liquid storage tank 41, or may be provided by appropriately changing the position as necessary.

Next, how the disinfecting mist spraying device 1 operates with the non-contact thermometer 110 will be described with reference to the flow chart of FIG. 4 .
As shown in FIG. 1, the non-contact thermometer 110 includes a camera 112 that captures a subject, a display 113 that projects an image captured by the camera 112, a body temperature measurement unit 114 that measures the body temperature of the subject in a non-contact manner, and a body temperature measurement unit 114. It has a body temperature display section 115 that displays the measured body temperature together with a comment.

First, in S301 of FIG. 4, it is confirmed whether or not the camera 112 has captured the subject. That is, when the camera 112 captures the position of the user's face within a predetermined range of the display 113 for a predetermined time, the non-contact thermometer 110 starts the next operation.
In S302 of FIG. 4, body temperature is measured. That is, body temperature measurement unit 114 measures the body temperature of the user.
Then, in S303 of FIG. 4, the body temperature and the like are displayed. That is, the body temperature display unit 115 displays the numerical value of the measured body temperature along with a comment such as "Your body temperature is normal."

Finally, in S304 of FIG. 4, the sterilization mist M is jetted for a predetermined time. That is, the sterilization mist spraying device 1 is automatically operated to evenly spray the sterilization mist M on the user. Before spraying the disinfectant mist M, for example, a comment such as "In order to protect yourself and others from the virus, the virus that adheres to your clothes, bags, and the whole body will be coated with a disinfectant." may be displayed on the body temperature display unit 115 or the like. Further, the ejection of the sterilization mist M may be performed simultaneously with the display of the body temperature and the like. That is, this flowchart is merely an example of the operation of the disinfecting mist spraying device 1 .

Since this sterilizing mist spraying device 1 can be used to sterilize an entire room, etc., its usage will be described with reference to FIG.
As shown in FIG. 5, the opening/closing lid 13 at the upper end of the case body 10 can be easily removed by simply lifting it upward. Furthermore, the sterilization mist holding cylinder lid 52 covering the upper end of the sterilization mist holding cylinder 50 located under the opening/closing lid 13 can also be easily removed.

As shown in FIGS. 5 and 3, when the opening/closing lid 13 and the sterilizing mist holding cylinder lid 52 are removed, the sterilizing mist spraying device 1 can be operated by operating the electric control unit 30 and the like. The sterilization mist M generated by the mist generator 40 is ejected from the upper part as it is. If this operation is performed in the room, the entire room is coated with a large amount of the sterilizing mist M with the sterilizing agent, making it possible to sterilize the room.

Now, the details of how the first embodiment described above has such a configuration and the effects thereof will be described below.

The inventors initially thought of connecting a sterilizing mist generator and a plurality of sterilizing mist ejection ports with a tubular member to eject the mist. This is because I thought that mist, like water and air, would blow out from the other end if it was blown in from one end.
Therefore, first, a hard polyvinyl chloride pipe (a so-called water pipe) having an inner diameter of 13 mm (minimum wall thickness of 2.2 mm) was made as a trial. However, as a result, the blowing mist was greatly reduced.

Next, a trial production was made using a rigid polyvinyl chloride tube having an inner diameter of 40 mm (minimum wall thickness of 3.6 mm). This is because I thought that if the pipe was made thicker, the amount of mist that would be reduced would be greatly reduced.
However, as a result, the blown mist was like half the generated mist.
Of course, if a sterilization mist generator with a higher mist generation capacity is used with this structure, the desired amount of mist ejection can be obtained, but this makes the entire device large and inefficient. Become.

The reason why mist decreases when it passes through such a pipe is that the mist is unstable and adheres to the inner wall as droplets as it passes through a pipe, tube, or the like. And if there are droplets on the inner wall, the mist is more likely to adhere and disappear. Therefore, it is considered that the amount of mist discharged from the spray holes is greatly reduced compared to the generated amount.

Therefore, the inventors conceived of storing the generated mist as it is in a tank and jetting it out from there. In other words, prepare a long square cylinder with the upper end closed as a tank, pour the mist generated by the sterilization mist generator from the open lower end as it is, and drill multiple holes with different heights on one side of the square cylinder to allow the mist to enter. was sprayed to obtain the desired amount of mist.

In this way, the sterilizing mist spraying device 1 capable of efficiently jetting a large amount of the sterilizing agent mist generated by the mist generator while minimizing the loss during the process was created.

By the way, in factories and offices, fresh air is conveyed through rectangular ducts or the like, and is ventilated by providing a plurality of outlets for blowing fresh air. I think that there are indications that if this duct were to stand vertically, it would have a similar configuration. But this is different. This is because the duct handles air, not mist.

Air is an inexhaustible resource, and it is difficult to degrade. On the other hand, there is a limit to the amount of mist that can be generated, and the mist disappears as droplets over time.
That is, when air is sent to an upright duct, for example, if air is sent from the lower part, the air inside the duct can be immediately blown out from a plurality of outlets.

On the other hand, as for the case of sending the mist, consider sending the generated mist from the lower end of an erected duct or sending the mist through a pipe. In this case, since the mist inside the duct disappears and becomes normal air, it is first necessary to replace the air inside the duct with mist in order to eject the mist. That is, it takes a long time to blow the mist from the plurality of injection holes after the mist is blown. Also, in this case, the mist will accumulate from the bottom of the duct, so the mist will be emitted from the injection holes at the bottom, and it will be difficult to spray the mist from all the injection holes. become.

In the sterilization mist spraying device, it is preferable to eject mist from all ejection ports within 5 seconds after the mist generator is activated, although it depends on the mist generator's generating capacity and the capacity of the square cylinder. This is because if the ejection of the mist is delayed, the user may lose interest in sterilization. Moreover, within 2 seconds is more preferable. This is because the user feels as if the mist is immediately ejected.

It is preferable that the rectangular cylinder used for the sterilizing mist spraying device has a horizontal cross-sectional area of 5000 square mm or more. This is because the area of contact with the inner wall of the square cylinder per unit volume of mist can be reduced. Further, it is more preferable that the cross-sectional area is 8000 square mm or more. This is because a large amount of mist can be delivered to the spout to realize a powerful mist spout.
Note that the height of the rectangular cylinder is assumed to be within 1.8 m in the description here.

It is preferable that the rectangular cylinder used for the sterilizing mist spraying device has a horizontal cross-sectional area of 70000 square mm or less. This is because a large amount of mist can be stored. Also, it is more preferable that the cross-sectional area is 50000 square mm or less. This is because, if the cross-sectional area is large, it will take a long time to fill, and a more powerful mist generator will be required. Also, it is more preferable that the cross-sectional area is 30000 square mm or less. This is because it can be stored compactly in the sterilization mist spraying device. The height of the rectangular tube shall be the same.

In the present embodiment, the sterilizing mist holding tube 50 is drawn as a substantially rectangular tube having the same cross-sectional area, but it is not limited to this. The substantially rectangular cross-sectional area of the upper portion of the rectangular tube may be configured to be smaller than the cross-sectional area of the lower portion. For example, one surface of the rectangular cylinder may be inclined. This is because, by configuring in this way, the mist inside reaches the upper ejection port more quickly, and the time until the mist is ejected from the ejection port is shortened.

In this embodiment, the filter lid 12 and the opening/closing lid 13 are provided on the upper surface of the case body 10, and the filter lid 12 sucks air through the filter. However, the present invention is not limited to this. For example, the opening/closing lid 13 may also be provided with a filter so that air is sucked from the entire upper surface. Also, an intake port may be provided on the upper side surface, the front surface, or the like. The intake air may be drawn from the lower part of the case body 10, but it is preferable to draw the air from the upper part. When air is sucked from above, the inside of the sterilizing mist holding cylinder 50 becomes the same temperature as the surrounding external air due to the air entering from the outside, the water droplets adhering to the inner surface of the cylinder are reduced, and the sterilizing mist M becomes water droplets. This is because it is possible to reduce the disappearance of

That is, including the housing, the sterilization mist spraying device can also be expressed as follows.
A sterilization mist spraying device having a vertically long housing, equipped with a sterilization mist generation unit that generates sterilization mist at the bottom inside the housing, and at the top of the sterilization mist generation unit inside the housing It is equipped with a sterilization mist ejection part for ejecting the sterilization mist generated by the sterilization mist generation part, and the sterilization mist ejection part has a cylindrical part whose upper end is closed, is equipped with the sterilization mist ejection port, the cross section is formed in a substantially rectangular shape, and the air intake port for the mist generated by the sterilization mist generation unit is provided at the top of the housing Bacteria mist spraying device.
In this way, by sucking air from the top, the air entering from the outside causes the internal sterilizing mist holding cylinder 50 to have the same temperature as the surrounding external air, and the water droplets adhering to the inner surface of the cylinder are reduced, sterilizing. It is possible to reduce the possibility that the mist M becomes water droplets and disappears.
