A left side view of an embodiment of the apparatus of the present invention. Fig. 8 is a cross-sectional explanatory view of Fig. 7.

In the drawings, the drawings are schematic diagrams showing the apparatus of the present invention. Therefore, at the time of productization, a more practical design can be suitably made as needed.

In the figure, reference numeral 1 denotes a container, and a discharge port 2 is provided in the upper portion of the container 1.

In the present embodiment, the container 1 is formed in a tubular shape, and more specifically, is formed into a cylindrical shape. However, the present invention is not limited to such a configuration as long as it does not deviate from the scope of the present invention. For example, it can also be formed into a rectangular tube shape. Tubular.

In the container 1, a needle electrode 3 whose both ends of the needle are oriented in the vertical direction is provided.

A high voltage, in particular a negative high voltage, is applied to the needle electrode 3 . This is to easily obtain an ion wind in which the flow rate of the negative discharge is higher than the flow rate of the positive discharge. However, a positive high voltage can also be applied in advance as needed.

By applying a negative high voltage to the needle electrode 3, corona discharge can be generated from the tapered front end (the respective ends of the upper end 31 and the lower end 32) of the needle electrode 3.

Further, in order to apply a high voltage to the needle electrode 3, although not shown, a high-voltage power supply device is additionally provided and connected to the needle electrode 3.

Further, a direct current of a negative high voltage of -4,000 V to -15,000 V is applied from the high voltage power supply device. However, as described above, a direct current of a positive high voltage, in particular, a direct current of a positive high voltage of 4,000 V to 15,000 V may be applied in advance as needed.

Below the needle electrode 3, specifically below the lower end 32 of the needle electrode 3 and above the bottom surface 11 of the container 1, a first cylindrical electrode 4 (the lower cylindrical electrode 4) is provided.

Further, above the needle electrode 3, specifically above the upper end 31 of the needle electrode 3 and below the discharge port 2, a second cylindrical electrode 5 having a discharge port 2 at its distal end is provided (the upper cylindrical electrode 5) ).

As described above, in the apparatus of the present invention, the needle electrode 3 is commonly used for the upper and lower cylindrical electrodes, that is, the first cylindrical electrode 4 (the lower cylindrical electrode 4) and the second cylindrical electrode 5 (the upper cylindrical electrode 5) ), to prevent waste.

Usually, when a negative high voltage (-4,000 to -15,000 V) is applied, the needle electrode 3 side is referred to as a positive side (anode), and the first cylindrical electrode 4 (lower cylindrical electrode 4) and Two cylindrical electrodes 5 (upper cylindrical electrode 5) side As the negative side (cathode).

As described above, by applying a high-voltage DC current between the needle electrode 3 and the first cylindrical electrode 4 (the lower cylindrical electrode 4) and the second cylindrical electrode 5 (the upper cylindrical electrode 5), The needle electrode 3 is corona-discharged between the first cylindrical electrode 4 (the lower cylindrical electrode 4) and the second electrode 5 (the upper cylindrical electrode 5) to separate the ion wind The needle electrode 3 side flows toward the first cylindrical electrode 4 (lower cylindrical electrode 4) side and from the needle electrode 3 side toward the second cylindrical electrode 5 (upper cylindrical electrode 5) side.

Here, the first cylindrical electrode 4 (the lower cylindrical electrode 4) and the second cylindrical electrode 5 (the upper cylindrical electrode 5) are the same in the cylindrical electrode, but the diameter is as shown in the figure. The length of the barrel is set to be different. In particular, it is preferable that the diameter of the first cylindrical electrode 4 (the lower cylindrical electrode 4) is set to be larger than the diameter of the second cylindrical electrode 5 (the upper cylindrical electrode 5). The electrons (e-) discharged from the first cylindrical electrode 4 (the lower cylindrical electrode 4) can be brought into contact with the liquid surface at a wide angle (wide range). However, the diameter and the length of the barrel can be set to be the same as needed.

In other words, first, the first cylindrical electrode 4 (the lower cylindrical electrode 4) promotes contact of the emitted electrons (e-) at a wide angle with the surface of the liquid stored in the liquid storage portion 9 to be described later. The reaction which evaporates and atomizes, therefore, sets its diameter to be large, and the length of the cylinder is set to be short.

On the other hand, the second cylindrical electrode 5 (the upper cylindrical electrode 5) is such that the liquid (droplet) which is atomized in the above manner is positively negatively charged, and the liquid is ejected in a laminar flow, so that the diameter is set. It is smaller than the first cylindrical electrode 4 (the lower cylindrical electrode 4), and the diameter is set to be relatively small, and the length of the cylinder is set to be smaller than the first cylindrical electrode 4 (the lower cylindrical electrode 4) )long And set the length of the barrel to be relatively long.

The first cylindrical electrode 4 (the lower cylindrical electrode 4) and the second cylindrical electrode 5 (the upper cylindrical electrode 5) are provided in a cylindrical shape below and above the needle electrode 3, and are grounded. And corona discharge is performed between the needle electrode 3 and the two electrodes, respectively, and a downward flow (downflow) is generated between the needle electrode 3 and the first cylindrical electrode 4 (the lower cylindrical electrode 4). The ion wind causes an upward flow (upflow) of ion wind between the needle electrode 3 and the second cylindrical electrode 5 (the upper cylindrical electrode 5). Strong ion wind can be generated by using a cylindrical electrode.

Further, the corona discharge is not a discharge like a fireworks spread, and in addition, if the electrode is touched during operation, since it is only static electricity, there is no concern about safety. Further, a known safety circuit can be appropriately incorporated as needed.

Further, a suction port 6 is opened in the side surface 12 of the container 1.

The shape and structure of the vicinity of the suction port 6 are particularly shown in the first, second, eighth, ninth, tenth, eleventh, twelfth and thirteenth drawings.

The air inlet pipe 7 provided from the side surface 12 of the container 1 is communicated with the air duct 7 of the first cylindrical electrode 4 (the lower cylindrical electrode 4) to form a flow path.

Thereby, the air duct 7 appears on the inner side of the tubular container 1 as a so-called double tube structure.

That is, the outside air is taken in through the air duct 7 on the inner side of the suction port 6, and another flow path is formed between the outer side of the air duct 7 and the inner side of the tubular container 1.

In addition, only the lower portion including the lower end 32 of the needle electrode 3 is here The inside of the air duct 7 is exposed, and the upper portion including the upper end 31 of the needle electrode 3 is not exposed in the air duct 7.

Therefore, in cooperation with the configuration in which the two flow paths are formed as described above, the second cylindrical electrode 5 (the upper cylindrical electrode 5) and the first cylindrical electrode 4 existing on the upper and lower sides thereof can be handled by only one needle electrode 3 Corona discharge between (the lower cylindrical electrode 4).

Further, a liquid storage portion 9 in which the liquid 8 is placed is provided below the first cylindrical electrode 4 (the lower cylindrical electrode 4).

The liquid storage unit 9 stores a liquid containing one or more components selected from the group consisting of an aromatic component, a sterilization component, and a deodorizing component.

As such an aromatic component, a disinfection component, and a deodorant component, a well-known material, such as a commercial item, can be used.

For example, examples of the aromatic component include aromatic oils derived from plant-derived natural flavors, essential oils, and other synthetic flavors.

In the apparatus of the present invention, corona discharge is performed between the lower end 32 of the needle electrode 3 and the first cylindrical electrode 4 (the lower cylindrical electrode 4) in the air duct 7, and the first passage is made from the suction port 6 through the first The cylindrical electrode 4 (the lower cylindrical electrode 4) flows downward (downflow) of the ion wind toward the surface of the liquid stored in the liquid storage portion 9.

On the other hand, in the apparatus of the present invention, the upper end of the needle electrode 3 and the second cylindrical electrode 5 (the upper cylindrical electrode 5) are corona-discharged outside the air duct 7, and are stored in the liquid storage. The liquid surface of the portion 9 passes through the second cylindrical electrode 5 (the upper cylindrical electrode 5) toward the upward flow (upflow) of the ion wind of the discharge port 2.

Also, in the device of the present invention, the use of corona discharge The resulting downward flowing (downflow) ion wind causes the liquid stored in the liquid storage portion 9 to evaporate and atomize and negatively charge the micronized liquid.
