The present invention relates to a spraying device.

Patent Document 1 below describes a deodorizing device in which an intermediate water tank is provided in a container for a deodorant liquid and an ultrasonic vibrator is arranged on the bottom surface of the intermediate water tank. Distilled water is contained in the intermediate water tank, and the distilled water is separated from the deodorant liquid in the container by a plastic film. The plastic film is fixed to the intermediate water tank. As a result, the deodorant component is suppressed from adhering to the ultrasonic vibrator, and the vibration of the ultrasonic vibrator is transmitted from the distilled water to the deodorant liquid via the plastic film.

Utility Model No. 309505

In the deodorizing device in Patent Document 1, a plastic film is fixed to the upper surface of the intermediate water tank. Therefore, in order to keep the plastic film in contact with the deodorant liquid and the distilled water, it is necessary to keep the distilled water inside the intermediate water tank at a high water level at all times. Therefore, it takes time and effort to manage.
Further, it is necessary to use the same plastic film even when the deodorant liquid is replaced with a drug having a different component. At this time, the plastic film may be washed, but it is necessary to wash the film while it is installed in the deodorizing device, resulting in poor workability. Therefore, it takes time and effort to manage.

An object of the present invention is to provide a spraying device capable of reducing management effort in consideration of the above facts.

The spraying device according to claim 1 separates a water tank, an ultrasonic vibrator arranged at the bottom of the water tank, a liquid in contact with the ultrasonic vibrator in the water tank, and a chemical liquid containing a decontamination agent. It comprises a removable flexible diaphragm.

According to the spray device of claim 1, the chemical solution containing the decontamination agent is separated from the liquid in contact with the ultrasonic vibrator by a diaphragm. Therefore, the liquid is not mixed with the chemical solution. As a result, it is possible to prevent the decontamination agent from adhering to the ultrasonic vibrator.

Further, the diaphragm arranged in the water tank is made flexible. Therefore, the diaphragm can separate the liquid from the drug solution regardless of the amount of the liquid. This eliminates the need to precisely adjust the amount of liquid. Therefore, management is not troublesome.

In addition, the diaphragm is removable. Therefore, the diaphragm can be removed or replaced with another diaphragm depending on the type of liquid or chemical solution. Therefore, it is possible to easily respond to changes in the chemical solution, and management is not troublesome.

The spraying device according to claim 2 includes an intake port provided with a fan, and a holding container provided facing the outside of the intake port and holding an adsorbent for adsorbing the decontamination agent.

According to the spray device of claim 2, air is taken into the inside of the spray device from the intake port by the fan. The intake port is provided facing a holding container that holds an adsorbent that adsorbs the decontamination agent. Therefore, the decontamination agent sprayed from the spraying device is suppressed from being taken into the inside of the spraying device from the intake port. As a result, it is possible to prevent the decontamination agent from adhering to the internal mechanism of the spraying device.

The spraying device according to claim 3 uses silica gel as the adsorbent.

In the spray device of claim 3, silica gel is used as an adsorbent. Since silica gel can be reused by heating, it saves resources as compared with the case of using an adsorbent that cannot be reused. In addition, silica gel is easily available because it is widely used as an adsorbent.

In the spraying device of claim 4, the decontaminating agent is hydrogen peroxide or peracetic acid.

In the spray device of claim 4, hydrogen peroxide or peracetic acid is used as the decontamination agent. Since hydrogen peroxide and peracetic acid are liquids at room temperature, they are easy to manage. Moreover, since it is widely used as a decontamination agent, it is easily available.

According to the spraying device of the present invention, management labor can be reduced.

Hereinafter, the spraying device according to the embodiment of the present invention will be described with reference to the drawings. The components shown by using the same reference numerals in each drawing mean that they are the same components. However, unless otherwise specified in the specification, each component is not limited to one, and a plurality of each component may exist. In addition, description of overlapping configurations and symbols in the drawings may be omitted. The present invention is not limited to the following embodiments, and can be carried out with appropriate modifications such as omitting the configuration or replacing it with a different configuration within the scope of the object of the present invention.

<Spraying device>
As shown in FIG. 1, the spraying device 10 according to the embodiment of the present invention includes a main body 12, a lid 14, a holding container 16, and a diaphragm 40.

A water tank 20 is formed in the main body 12. In this water tank 20, the wall portion 20A is formed in a cylindrical shape, and the bottom portion 20B is formed in a mortar shape. That is, the bottom portion 20B of the water tank 20 is formed so as to be inclined downward from the peripheral portion connected to the wall portion 20A toward the central portion.

An ultrasonic vibrator 30 is provided at the center of the bottom 20B (at the bottom of the gradient). The ultrasonic vibrator 30 comes into contact with the liquid (for example, distilled water or tap water) W1 injected into the water tank 20. The ultrasonic vibrator 30 is electrically connected to a drive device 34 arranged in a space below the water tank 20 in the main body 12, and vibrates when the drive device 34 is driven. A power cable (not shown) is connected to the drive device 34, and power is supplied to the drive device 34 by this power cable.

A diaphragm 40 is detachably provided in the water tank 20. The diaphragm 40 is a flexible film obtained by molding polyvinylidene chloride or polyethylene into a sheet shape. As shown in FIG. 2, the diaphragm 40 is installed in a state where the liquid W1 is injected into the water tank 20, and is arranged so as to cover the surface of the liquid W1. Further, the diaphragm 40 is arranged so as to cover the inner side surface of the wall portion 20A in the water tank 20.

As shown in FIG. 1, the chemical solution W2 containing the decontaminating agent is injected into the water tank 20 from above the diaphragm 40. Due to the pressure of the chemical solution W2, the diaphragm 40 comes into close contact with the liquid W1. Further, due to the pressure of the chemical solution W2, the diaphragm 40 comes into close contact with the inner surface of the wall portion 20A.

The diaphragm 40 continuously covers the surface of the liquid W1 and the inner surface of the wall portion 20A. Further, the diaphragm 40 is folded back toward the outer surface side of the wall portion 20A. Therefore, the chemical solution W2 is separated from the liquid W1 via the diaphragm 40. As a result, the mixture of the liquid W1 and the chemical solution W2 is suppressed. It is assumed that the liquid W1 is injected in an amount equal to or more than the amount covering the entire upper surface of the ultrasonic vibrator 30.

The main body 12 is provided with a space below the water tank 20 for installing the drive device 34. An intake port 22 is provided in this space. The intake port 22 is an opening that communicates the outside and the inside of the main body 12, and the intake port 22 is provided with a fan 32. The fan 32 is driven by a motor (not shown). This motor is electrically connected to the drive device 34 described above. As a result, the ultrasonic vibrator 30 and the fan 32 operate in conjunction with each other.

In the main body 12, the air taken into the space below the water tank 20 in the main body 12 by being driven by the fan 32 is allowed to flow to the outside of the water tank 20 (outside the wall 20A) as shown by the arrow V1. A slit 24 for the purpose is formed.

The lid 14 covers the main body 12 so as to cover the water tank 20 of the main body 12. The lid 14 forms a gap M with the water tank 20 in a state of being attached to the main body portion 12. Further, at the upper end portion of the lid 14, a discharge port 14A that communicates the gap M with the outside (for example, the indoor space to be decontaminated) is formed. The air flowing from the slit 24 to the outside of the water tank 20 (and the inside of the lid 14) flows around the water tank 20 through the gap M. Then, as shown by the arrow V2, this air is discharged to the outside from the discharge port 14A.

The holding container 16 is provided below the main body 12 so as to face the outside of the intake port 22. The holding container 16 can hold various adsorbents that adsorb moisture and chemical substances in the air. In the present embodiment, silica gel S as an adsorbent is held in the holding container 16.

A slit 16A is provided on the side surface of the holding container 16. When the fan 32 of the main body 12 is driven, air flows into the holding container 16 through the slit 16A. This air is further sucked into the inside of the main body 12 (the space below the water tank 20) through the intake port 22.

<Drive of spray device>
When the drive device 34 is driven, the ultrasonic vibrator 30 starts to vibrate. The drive device 34 starts driving when the user energizes the drive device 34 using a switch or the like (not shown).

When the ultrasonic vibrator 30 starts to vibrate, the vibration propagates to the liquid W1. Then, the vibration of the liquid W1 propagates to the chemical liquid W2 through the diaphragm 40. The chemical solution W2 becomes a mist-like spray solution W3 by vibration and is discharged into the gap M between the lid 14 and the water tank 20.

Further, when the drive device 34 is driven, the fan 32 starts to rotate. As the fan 32 rotates, air flows from the intake port 22 to the inside of the main body 12 (outside the wall 20A) as described above. This air suppresses overheating of internal mechanisms such as the drive device 34 and the ultrasonic vibrator 30. Further, as shown by arrows V1 and V2, this air is discharged to the outside through the gap M between the lid 14 and the water tank 20. Due to this flow of air, the spray liquid W3 is discharged to the outside from the discharge port 14A.

<Action and effect>
According to the spraying device 10 according to the embodiment of the present invention, as shown in FIG. 1, the chemical solution W2 containing the decontaminating agent is separated from the liquid W1 in contact with the ultrasonic vibrator 30 by the diaphragm 40. Therefore, the liquid W1 is not mixed with the chemical solution W2. As a result, it is possible to prevent the decontamination agent from adhering to the ultrasonic vibrator 30.

Further, the diaphragm 40 arranged in the water tank 20 is made flexible. Therefore, the diaphragm 40 can separate the liquid W1 and the chemical solution W2 regardless of the amount of the liquid W1. As a result, it is not necessary to strictly adjust the amount of liquid W1. Therefore, management is not troublesome.

Further, the diaphragm 40 is removable. Therefore, the diaphragm 40 can be removed or the diaphragm 40 can be replaced with another diaphragm depending on the type of the liquid W1 or the chemical liquid W2. Therefore, it is possible to easily respond to changes in the chemical solution W2, and management is not troublesome.

Further, according to the spraying device 10 according to the embodiment of the present invention, air is taken into the inside of the spraying device 10 from the intake port 22 by the fan 32. The intake port 22 is provided facing the holding container 16 that holds silica gel S as an adsorbent for adsorbing the decontaminating agent. Therefore, the decontamination agent contained in the spray liquid W3 sprayed from the spray device is suppressed from being taken into the inside of the spray device 10 from the intake port 22. As a result, it is possible to prevent the decontamination agent from adhering to the internal mechanism of the spraying device 10 (for example, the driving device 34 or the like).

Further, according to the spraying device 10 according to the embodiment of the present invention, hydrogen peroxide or peracetic acid is used as the decontamination agent. Since hydrogen peroxide and peracetic acid are liquids at room temperature, they are easy to manage. Moreover, since it is widely used as a decontamination agent, it is easily available.

In addition, the concentrations of hydrogen peroxide and peracetic acid can be easily adjusted. For example, when the concentration of hydrogen peroxide or peracetic acid in the chemical solution is increased, the same decontamination effect can be obtained even if the spray amount of the spray solution W3 is reduced. Therefore, it is possible to efficiently decontaminate while suppressing an increase in the humidity of the indoor space to be decontaminated.

Further, according to the spraying device 10 according to the embodiment of the present invention, silica gel is used as an adsorbent. Since silica gel can be reused by heating, it saves resources as compared with the case of using an adsorbent that cannot be reused. In addition, silica gel is easily available because it is widely used as an adsorbent.

<Other Embodiments>
In the above embodiment, silica gel is used as the adsorbent, but the embodiment of the present invention is not limited to this. For example, activated carbon may be used as the adsorbent. The decontamination agent can also be adsorbed by using activated carbon.

Further, the spraying device 10 may be configured not to include the holding container 16. For example, instead of the holding container 16, a paper carton or the like containing an adsorbent may be arranged facing the intake port 22. Even with such a configuration, the decontamination agent can be adsorbed.

Further, in the spraying device 10, it is not always necessary to use the adsorbent regardless of the presence or absence of the holding container 16. For example, if the decontaminating agent contained in the spray liquid W3 discharged from the discharge port 14A is sufficiently diluted in the air to the extent that it does not affect the internal mechanism of the spray device 10, it is not necessary to use an adsorbent. The spraying device 10 can be driven.

Further, although the spray device 10 is provided with slits 16A and 24 for allowing air to flow, the embodiment of the present invention is not limited to this. For example, these slits 16A and 24 may be mesh-like openings (for example, mesh) or the like.

Further, for example, the main body portion 12 may not be provided with the slit 24. In this case, the air taken into the main body 12 by the fan 32 is less likely to flow into the gap M. However, due to the pressure difference between the outside of the spray device 10 and the gap M, the mist-like spray liquid W3 is discharged from the discharge port 14A.

Further, in the above embodiment, hydrogen peroxide or peracetic acid is used as the decontamination agent, but the embodiment of the present invention is not limited to this. The type of decontamination agent can be appropriately selected according to the decontamination target. For example, when the decontamination target is a substance that generates "odor", a deodorant may be used as the decontamination agent. Such a decontamination agent may be a special product produced for a specific decontamination target or a commercially available product.
