Functional components to the impregnation of the water conservation parts 11 of porous body or corpus fibrosum, adhere to, undertaken by following manner: dissolving cooperates the material that functional components gets more than a kind or 2 kinds in the binder aqueous solution of inorganic or organic compound, makes water conservation parts 11 this aqueous solution of contact and dry solidifications.
Carry the water conservation parts 11 of holding functional components, play for the effect of the functional components bedding plant that is provided with to discharging needle part 12 the supplied with strippings aqueous solution of functional components, water conservation parts 11 desired characteristics, the 1st is the moisture-holding capacity of the aqueous solution, and the 2nd is to be set as the structure of the aqueous solution of functional components of can having supplied with stripping for a long time.That is, slowly stripping then can be for a long time from discharging needle part 12 release function compositions in water if can utilize the adhesive of inorganic or organic compound to make functional components.
Like this, when supplying with water to carrying the water conservation parts 11 of holding functional components from water supply mechanism 3, and on the water conservation parts 11 of water conservation state, connect the negative pole 5 of DC high-voltage power supply 4 and when making the charged one-tenth negative polarity of water conservation parts 11, electric current flows to the many terminal part 12a... that discharge needle part 12... that are provided with highlightedly on the water conservation parts 11, cause the existing picture of nature discharge, utilize this discharge process to produce particle wind, utilize this particle wind, be fixed on functional components on the water conservation parts 11 and move on one side and discharge needle part 12 (1～100nm) the fine mist 8... that is invisible to the naked eye discharges in a large number with nano-grade size on one side with the form of the aqueous solution.And according to the purposes difference of using, material that can be by selecting to discharge needle part 12, suitably design discharges the length of needle part 12 and shape, the radical of diameter or terminal part 12a, designs water arbitrarily or contains the burst size of the mist of functional components.

Again, contain the mist 8 of functional components,, be in the atomic thin state of the wall of can not getting wet etc., so can make it arrive in indoor or the car or in the storehouse of freezer or its corner by the wind of fan etc. because its particle diameter is the nano-grade size of 1～100nm.
And,,, use or therapeutic medical mist generating device thereby be expected to be used for beauty care device so be expected to have the effect that skin is preserved moisture for a long time owing to the mist that can obtain to contain to the high ultra tiny functional components of the impregnability of skin.
Below, in vitamin C mist release test equipment 20 shown in Figure 10, carry out the mist release experiment with regard to the release needle part 12 of the terminal part 12a of different shape, relatively inquire into nanometer mist release performance, its result is described.
And, as shown in figure 11, prepare the variform release needle part of multiple terminal part 12a 12..., each is discharged needle part 12 be arranged on highlightedly on the water conservation parts 11, nanometer mist release performance is compared evaluation.The release needle part of preparing 12 is a cylindrical shape except that terminal part 12a, and, (with reference to Figure 11 (c)) of (with reference to Figure 11 (b)), the triangular pyramid shape of (with reference to Figure 11 (a)), the circular arc of the elongate of circular arc, (with reference to Figure 11 (d)), (with reference to Figure 11 (e)) of general planar shape of elongated sharp triangular pyramid shape are arranged about terminal part 12a.Each discharges needle part 12 and is made of polyester fiber.
And the radical of the release needle part 12... that is provided with highlightedly on the water conservation parts 11 is made as 9, and third rare system case 28 is arranged on the indoor of 25 ℃ of temperature, humidity 55%.Again, 0.5% ascorbic running water has been dissolved in injection in accommodating container 13.And, the needle part 12 that respectively discharges of Figure 11 (a)～Figure 11 (e) was switched on 6 hours with the DC negative voltage of 8kV.
In experiment, the vitamin C concentration of dissolving in the pure water that is recovered in the container 30 is tried to achieve according to the numerical value of the DPPH radical reduction amount of ascorbic acid.This method is the character (antioxidation) that makes the disappearance of DPPH free radical owing to its concentration when utilizing dissolution of ascorbic acid in DPPH solution, and uses the concentration that contains of spectrophotometer quantitative analysis ascorbic acid.In triangular flask, put into 5cc DPPH is modulated to the material of 0.125mmol/L alcoholic solution, this triangular flask is put into 30 ℃ the tank that is called constant temperature oscillator.At first, measure the peak value of DPPH alcoholic solution, put into the 1cc sample.If non-oxidizability is arranged in the sample, then the free radical of DPPH alcoholic solution reduces, and solution is from the purple yellowing.Deduct peak value at this moment from the peak value of DPPH alcoholic solution, resulting value is the value of expression resistance to oxidation.
Figure 12 is expression conduction time and the chart of the relation of the ascorbic acid concentrations that records, and (a)～(e) in the chart represents the result corresponding with the release needle part 12 of Figure 11 (a)～Figure 11 (e) respectively.If from this graph observer, then decidable goes out, shown in Figure 11 (d), be sharp shape if discharge the shape of the terminal part 12a of needle part 12, or shown in Figure 11 (e), be flat condition, even then prolongation ascorbic acid conduction time also is difficult to improve.On the other hand, judge, terminal part 12a has the release needle part 12 of circular arc to be fit to discharge the mist that contains functional components shown in Figure 11 (a) or Figure 11 (b).
Below, the vitamin C mist release test equipment 20 of use Figure 10 changes the radical, diameter and the material that discharge needle part 12, and nanometer mist burst size is compared research, and result of experiment is described.
About discharging needle part 12, utilize polyester fiber and porous ceramic to form the cylindrical shape parts of diameter 2mm and 4mm respectively.That is, prepare 4 kinds and discharge needle part 12, length all is made as 30mm.And, test on water conservation parts 11, being provided with 9,18 situations that respectively discharge needle part 12 highlightedly.Experimental conditions (indoor temperature and moisture, voltage, the running time of case 28 are set) and evaluation method and Figure 11, experiment illustrated in fig. 12 are the same.
Figure 13 is expression conduction time and the chart of the relation of the vitamin release concentration (ascorbic acid concentrations) that records.Find from this chart, if the material of porous matter formed body 2 is polyester fiber and porous ceramic, even then design water retention roughly the same, also can be variant.
Its reason can think that the difference that discharges the last energy-absorbing power of needle part 12 has played bigger influence.The reason of Kao Lving has like this: under the situation of polyester fiber, being formed as fiber all is the states that gather along its length, water moved with about 30 seconds concerning the length orientation that discharges needle part 12, and it is relative with it, if ceramic fibre, then the matrix of porous body is the mesh state, is not easy to move.
Secondly, find that moving of diameter detailed rules and regulations water is slower, the further tendency that reduces of mist burst size of unit interval is arranged.Again, though can not confirm tendency from the chart of Figure 13, when discharging the humidification ability of needle part 12, because even the vitamin C mist is few, also can be from discharging needle part 12 whole water transpirations, thus if take temperature from humidification, then and polyester fiber system between significance difference little.Because the release needle part of polyester fiber system is with foregoing structure moulding, thus with the ceramic phase ratio, few from rising on every side amount.
When hope utilizes the nanometer mist to obtain deodoriging properties or degerming performance, or discharge in the time of to look to the composition of volatilization power is arranged as the vitamin C of functional components or catechuic acid etc., polyester fiber system proper, and paying attention to humidification power, or when require discharging needle part 12 and having anti-flammability, porous ceramic system proper.
If change the porosity of the porous body of pottery system, then can control water retention to a certain extent, but can not obtain the waterborne suction speed equal with the polyester fiber member made.And when wishing big moisture-holding capacity, the intensity of porous body self will descend, the tendency that exist because of assembling operation or the vibration when carrying etc. fractures or the danger of breaking increases.
Then, in cleaning mist release test equipment 21 shown in Figure 14, just, carried out the damping test to the system of (cleaning) mist of the indoor release nano-grade size that can not fully tackle with air purifier or room air conditioner.
This release test equipment 21, have porous matter formed body 2, water supply mechanism 3, make the device for generating high voltage (DC high-voltage power supply) 4 of porous matter formed body 2 charged one-tenth negative polarity, porous matter formed body 2 is the same with the equipment 20 of Figure 10 with these points in water supply mechanism 3 is arranged on aluminum case 28.And this release test equipment 21 comprises: be arranged on the bottom surface in the case 28 and stir air (axial flow) fan 22 of mist and be arranged in the case 28 and measure humidity and change (digital) humiture data logger 23.The shape of case, experiment condition (indoor air temperature, the humidity of case 28 are set) and Figure 11, experiment illustrated in fig. 12 are the same.
About discharging needle part 12, utilize the cylindrical polyester fiber of length 30mm diameter 3mm to form.And, when the radical of the release needle part 12 that is provided with highlightedly on the water conservation parts 11 is made as 6,12,18,24, applies 5kV, 10kV, these 3 kinds of DC negative voltages of 15kV and test.
And, the relation of the humidity (%) in expression conduction time and the case that records 28 is shown in table 1.According to the result of table 1 as can be known, as the radical of the release needle part 12 of cleaning mist production part, as prediction like that, to the mist amount influence that produces greatly.And, when radical is identical, can confirm to clean the size variation of the generation of mist 8 with the voltage that applies.The numeral % of table 1.

As described above, electrostatic atomization apparatus of the present invention comprises: the release by porous matter is set on the water conservation parts 11 of porous matter highlightedly parts 12 slightly forms and has a water imbibition, water-retaining property and the porous matter formed body 2 of going up the suction characteristic, make the DC high-voltage power supply 4 of porous matter formed body 2 charged one-tenth negative polarity with on this porous matter formed body 2, being connected negative pole 5, and, not relative positive polarity with the porous matter formed body 2 charged negative polarity that form to the utmost point, so, can cause the nature electric discharge phenomena from the release needle part 12... of porous matter, utilize wind to discharge the mist of nano-grade size in a large number.And, since do not have positive to the utmost point, so in the mist that discharges, do not have ozone generating fully.And, can efficiently functional components be included in interior atomizing.
Again, discharge needle part 12, have curved surface shape that forms the band circular arc and the terminal part 12a that is used for concentrating the mist 8 that produces diameter 1～50nm, so, can prevent that electric charge from too concentrating and produce arc discharge.
Again, owing to constitute, the aqueous solution 18 that contains the fixedness functional components is carried to be held on the water conservation parts 11, contains the mist 8 of fixedness functional components from discharging needle part 12 releases, so can tackle the improvement of various atmospheres.And, can obtain deodorizing, bactericidal action effectively.
Again, owing to discharging needle part 12 and water conservation parts 11 is with the porous body of ceramic material, synthetic resin material, metal material or compound formation the more than a kind or 2 kinds in the fiberizing body, so can realize water absorbing force and good release needle part 12 and the water conservation parts 11 of moisture holding capacity.
Again, because the water retention of water conservation parts is 30%～150% and sets to such an extent that be higher than the water retention that discharges needle part 12, and the last suction speed of the water of release needle part 12 is in 60 seconds, so, the aqueous solution that contains functional components can not stayed water conservation parts 11, and can supply with or stripping to discharging needle part 12.
Again, have the clavate shape owing to discharge needle part 12, so, discharge the mist 8 that contains functional components easily, discharge needle part 12... by being provided with many highlightedly, can increase the burst size that contains functional components mist 8.
