BEST MODE FOR CARRYING OUT THE INVENTION

In what follows, a capsule and an electrostatic atomizing device according to preferred embodiments of the present invention will be described in detail with reference to the appended drawings.

The electrostatic atomizing device of the present invention may be mounted in different types of air conditioning apparatuses, such as air cleaners, or air conditioners, or may be fabricated as a separate individual device.

The electrostatic atomizing device of the present invention uses a disposable capsule having an amount of functional water solution impregnated in a porous medium, such as a ceramic or carbon fiber electrode, enough to use about 2˜3 hours for preventing a scaling phenomenon in which an ejection pin is blocked from taking place.

Moreover, the electrostatic atomizing device of the present invention uses the disposable capsule which can be placed in the device easily for the user to use a functional water solution of user's selection.

Referring to FIG. 2, the disposable capsule 50 in accordance with a first preferred embodiment of the present invention may be fabricated in different shapes, such as a small sized cylinder, or a small sized polygonal pillar, such as a square pillar, hexagonal pillar, and octagonal pillar, the ejection pin 51 which is a porous medium has the functional water solution 52 impregnated therein, and the capsule has a surface thereof sealed with a sealing member 53, such as aluminum foil, for preventing the functional water solution 52 from dispersing through the ejection pin 51, naturally.

If a pressing member 54 like a piston in a rear side of the ejection pin 51 is moved by external force, for an example, pressing with a user's hand, the ejection pin 51 projects to an outside of the capsule penetrating the sealing member 53. Since the pressing member 54 and the sealing member 53 form a top and a bottom sides of the capsule 50 of the cylindrical or polygonal pillar respectively, and a side of the capsule 50 is formed of a sealing member of a solid material, such as plastic, the ejection pin 51 is enclosed so as not to be exposed to an outside of the capsule.

Referring to FIG. 3, the ejection pin 51 projected to an outside of the disposable capsule thus is placed in a hole in a driver 60 formed in a front or a side of the air conditioning apparatus, such as the air cleaner, and the air conditioner.

The driver 60 has a structure similar to a cigar jack insert, or a ball pointed pen spring, to enable a conductor that can apply a voltage to be brought into contact with the ejection pin 51.

Referring to FIG. 4, since the driver 60 has a voltage applying portion 61 of a conductor to be in contact with the ejection pin 51 being inserted into an inside through a hole provided thereto, if the user presses the pressing member 54 of the disposable capsule with a hand in a state the disposable capsule 50 is matched with the hole in the driver 60, the ejection pin 51 is inserted in, and brought into contact with, the voltage applying portion 61 through the hole in the driver as the ejection pin 51 penetrates through the sealing member 51, and is projected to the outside of the disposable capsule.

And, if the user pushes the pressing member 54 of the disposable capsule further, since the spring (Not shown) in the driver 60 comes into action, the air conditioning apparatus and the disposable capsule perfectly fastened closely. In this time, since a voltage is applied to ejection pin 51 through the voltage applying portion 61, the functional water solution 52 impregnated in the ejection pin 51 is atomized to form the nano-sized super fine mist.

The mist formed thus is discharged to an outside of the air conditioning apparatus carried on an air flow generated by the air conditioning apparatus, wherein unipolar charged droplets at a droplet atomizing voltage (For an example, 6˜7 KV) from the voltage applying portion 61 are carried by the air flow and discharged to the outside of disposable capsule, and has improved spatial diffusibility by repulsive force among the droplets.

Referring to FIG. 5, according to a result of experiment of the present invention, the mist has a particle size in a level of 20 nm in average, and, as the functional water solution, different materials, such as vitamin C (L-ascorbic acid),phytoncide, a solution of aroma perfume, and so on may be used.

Eventually, the user may use the disposable capsule 50 by selecting and inserting the disposable capsule 50 having the functional water solution of a desired composition impregnated therein in the driver 60 of a cigar jack shape provided in the front or the side of the air conditioning apparatus, simply.

In the meantime, FIG. 6 is a perspective view illustrating a disposable capsule and a driver in accordance with a second preferred embodiment of the present invention.

Since a non-conductive liquid, such as a natural essential oil, for an example, lavender, rosemary, chamomile, and so on, has almost no ions which can serve as a charge, and very low electric conductivity, it is not possible to charge the non-conductive liquid, easily.

Referring to FIG. 6, the disposable capsule in accordance with a second preferred embodiment of the present invention suggests using a charge injection type disposable capsule 70 of a cylinder with a circular hole formed therein, but not limited to the cylinder or the circular hole, but may have different shapes, such as a square, a pentagon, a hexagon, and so on, including an ejection pin 71 of a shape, for an example, a cylinder shape, mounted in a length direction of the hole in the cylinder, a functional water solution 72 impregnated in the ejection pin 71 of a porous medium, a needle of electrode 73 passed both through a side of the disposable capsule and a surface of the ejection pin 71 for being brought into contact with the function water solution 72, with a portion of the needle of electrode 73 projected to an outside of the disposable capsule. The needle of electrode 73 may be formed of tungsten or stainless steel having a low work function for inducing stable charge injection.

The air conditioning apparatuses, such as the air cleaner or the air conditioner, may have a driver 80 of a tray shape mounted therein in a front or a side thereof for inserting the disposable capsule 70 having the portion of the needle of electrode 73 projected therefrom in a width direction. As shown in FIG. 6, the driver 80 has a semi-circular support 81 for supporting the cylindrical disposable capsule, an electrode hole 82 formed therein for applying a voltage to the needle of electrode 73 projected from the side of the disposable capsule 70, and two donut shaped first ground electrode 83 and second ground electrode 84 mounted adjacent to two bottoms of the disposable capsule to be inserted in the support 81.

And, referring to FIG. 7, since the driver 80 may be fabricated in a tray shape which is inserted in or ejected from the air conditioning apparatus, the user seats the disposable capsule 70 by inserting the disposable capsule 70 from an upper side to a lower side simply in a state the tray shaped driver 80 is ejected, and, if the driver 80 having the disposable capsule 70 seated therein is inserted in the air conditioning apparatus, a high voltage is applied to the needle of electrode 73 through the electrode hole 82, to apply the high voltage between the needle of electrode 73 and the first ground electrode 83 and the second ground electrode 84 making the needle of electrode 73 to emit electrons.

And, a fluid in the vicinity of the electrons emitted thus is charged, so that the fluid charged thus is atomized and ejected to an outside of the disposable capsule from both ends of the ejection pin 71 by electric force stronger than surface tension of the fluid, thereby ejecting nano-sized super fine mist from both sides of the ejection pin 71.

Though FIG. 7 illustrates two ground electrodes 83 and 84 arranged at a length distance of the capsule to be in contact with the two bottom of the capsule in the driver 80, the present invention is not limited to this, but only one ground electrode may be arranged on one side, while the other side may have a stopper arranged at the length distance of the capsule for securing the capsule thereto.

Eventually, the user may use the disposable capsule 70 having a functional water solution of a desired composition impregnated therein by inserting the disposable capsule 70 in the tray shaped support of the driver 60 to the front or the side of the air conditioning apparatus, simply.

In the meantime, FIG. 8 is a perspective view illustrating a disposable capsule in accordance with a third preferred embodiment of the present invention. As described before, since a non-conductive liquid, such as a natural essential oil, for an example, lavender, rosemary, chamomile, and so on, has almost no ions which can serve as a charge, and very low electric conductivity, it is not possible to charge the non-conductive liquid, easily.

Referring to FIG. 8, the disposable capsule in accordance with a third preferred embodiment of the present invention suggests using a charge injection type disposable capsule 90 of different shapes, such as a small sized cylinder or polygonal pillar, including a functional water solution 92 impregnated in an ejection pin 91 of a porous medium, and a needle of electrode 93 passed through a bottom of the disposable capsule for being brought into contact with the functional water solution 92, with a portion of the needle of electrode projected to an outside of the disposable capsule. The needle of electrode may be formed of tungsten or stainless steel having a low work function for inducing stable charge injection.

The air conditioning apparatuses, such as the air cleaner or the air conditioner, may have a driver 100 of a vertical tray shape mounted therein in a front or a side thereof for inserting the disposable capsule 90 in a vertical direction to have the portion of the needle of electrode 93 projected therefrom. As shown in FIG. 8, the driver 100 includes a vertical semi-circular support 101 for supporting the disposable capsule to be inserted in a length direction, an electrode hole 102 formed therein for applying a voltage to the needle of electrode 93 projected through a bottom of the disposable capsule 90, and a donut shaped first ground electrode 103 mounted to a portion thereof the disposable capsule is to be seated thereon. The support 101 has a shape varied with an outside shape of the capsule for supporting the capsule, wherein, if the capsule is a cylindrical pillar, the support is semi-circular, and, if the capsule is polygonal, the support has a shape matched to the polygonal shape.

And, referring to FIG. 9, since the driver 100 may be fabricated in a vertical tray shape which is inserted in or ejected from the air conditioning apparatus, the user seats the disposable capsule 90 by inserting the disposable capsule 90 in a standing position in a length direction in a state the tray shaped driver 100 is ejected, and, if the driver 100 having the disposable capsule 90 seated therein is inserted in the air conditioning apparatus, a high voltage is applied to the needle of electrode 93 through the electrode hole 102, to apply the high voltage between the needle of electrode 93 and the first ground electrode 103 making the needle of electrode 93 to emit electrons.

And, the fluid in the vicinity of the electron emitted thus is charged, so that the fluid charged thus is atomized and ejected to an outside of the capsule by an electric force stronger than a surface tension of the fluid, thereby ejecting nano-sized super fine mist from both sides of the ejection pin 91.

When the capsule 90 is fastened to the driver 100 with the needle of electrode 93 inserted in the electrode hole 102, it is possible to make the first ground electrode 103 movable in a length direction such that the first ground electrode 103 is in contact with a bottom or a top of the capsule 90 having no needle of electrode 93 formed thereon.

As have been described, the capsule and the electrostatic atomizing device of the present invention have the following advantages.

While this invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that technical aspects of the present invention are not limited to the exemplary embodiments suggested in the specification, but, though a person of an ordinary skill in this field of art who understand the technical aspects of the present invention can suggest another exemplary embodiment by modifications, changes, removal, and addtion of constituent elements within a range of technical aspects the same with the present invention, it may also be within a range of right of the present invention.
