Description
Technical Field
The present invention relates to a charged particle generating device that generates charged particles containing at least one of ions and charged corpuscle water by electric discharge, and a hair care device provided with the charged particle generating device.
Background
Charged particles such as ions and charged water microparticles, particularly charged microparticles having a size of nanometer or less, are widely used for hair care and beauty care purposes. For example, japanese patent application laid-open No. 2006-826 describes a device for generating charged particulate water by discharging an electrode where dew condensation occurs.
Disclosure of Invention
However, in the conventional technique of applying a high voltage only to the discharge electrode, the emission direction of the charged particles generated by the discharge is unstable. Therefore, by disposing the counter electrode at a position facing the discharge electrode, discharge can be stabilized, and the emission direction of the charged particles can be stabilized. However, due to the arrangement of the counter electrode, part of the charged particles such as charged corpuscle water and ions generated by the discharge is captured by the counter electrode and cannot be emitted, and thus the emission amount of the charged particles is reduced.
A charged particle generating apparatus according to an embodiment of the present invention includes: a discharge electrode; a counter electrode disposed at a predetermined interval from the discharge electrode; and a voltage applying unit for applying different potentials to the discharge electrode and the counter electrode. Further, by performing electric discharge between the discharge electrode and the counter electrode, charged particles including at least one of ions and charged corpuscle water are generated. Further, the voltage applying unit applies the potential so that the polarities of the potentials applied to the discharge electrode and the counter electrode are the same and the absolute value of the potential applied to the discharge electrode is larger than the absolute value of the potential applied to the counter electrode.
With the above configuration, the emission efficiency of charged particles generated by discharge can be improved.

The following embodiments are merely examples of the charged particles according to the present invention. Therefore, the following embodiments are referred to in the present invention, and the scope of protection is defined by the terms of the claims, and not limited to the following embodiments. Therefore, among the components of the following embodiments, components that are not recited in the independent claims representing the uppermost concept of the present invention are not essential to achieve the technical problem of the present invention, and are described as components constituting a preferred embodiment.
The drawings are schematic views in which emphasis, omission, and scale adjustment are appropriately performed to show the present invention, and may be different from the actual shape, positional relationship, and scale.
Fig. 1 is a cross-sectional view schematically showing a charged particle generator. The charged particle generating apparatus 100 will be described below with reference to fig. 1.
The charged particle generating apparatus 100 is an apparatus for generating charged particles 200 including at least one of ions and charged corpuscle water by electric discharge, and the charged particle generating apparatus 100 includes: a voltage applying part 110, a discharge electrode 120, and a counter electrode 130. In the case of the present embodiment, the charged particle generating apparatus 100 further includes a water supply unit 140 that supplies water to the discharge electrode 120.
The voltage application unit 110 has a function of applying different potentials to the discharge electrode 120 and the counter electrode 130, respectively. The voltage application unit 110 is electrically connected in series between the discharge electrode 120 and the counter electrode 130, and a single loop discharge circuit is formed by the voltage application unit 110, the discharge electrode 120, and the counter electrode 130. The voltage applying unit 110 is not particularly limited. For example, the voltage applying unit 110 may include a power supply that generates a dc or ac high voltage, or may include a circuit that converts electric power supplied from an ac power supply into a dc high voltage.
In the present embodiment, the voltage applying unit 110 includes: a pair of power receiving terminals 111 that function as voltage supply units that receive a dc high voltage supplied from an external power supply 210; a resistor 112; and GND 113 which determines the reference potential of the discharge circuit.
The resistor 112 is a means for adjusting the potential so that the polarities of the potentials applied to the discharge electrode 120 and the counter electrode 130 are the same, and the absolute value of the potential applied to the discharge electrode 120 is larger than the absolute value of the potential applied to the counter electrode 130. One end of the resistor 112 is electrically connected to GND 113 which is a reference potential, and the other end is electrically connected to the counter electrode 130. By connecting the resistors 112 as described above, the potential applied to the discharge electrode 120 > the potential applied to the counter electrode 130 > the reference potential, or the potential applied to the discharge electrode 120 < the potential applied to the counter electrode 130 < the reference potential can be realized. Specifically, discharge occurs between the discharge electrode 120 and the counter electrode 130, and a current flows through the discharge circuit, so that a voltage drop occurs in the resistor 112, and the potential relationship of the three potentials described above is realized.
The GND 113 need not be actually grounded, and may be a reference potential of a discharge circuit such as 0V. Fig. 1 shows a case where GND 113 is connected between power receiving terminal 111 and resistor 112, but the present invention is not limited to this. For example, the GND 113 may be connected to the external power supply 210.
In the present embodiment, specifically, a direct-current voltage of 1kV or more is supplied between the pair of power receiving terminals 111, and a resistor 112 having a resistance value of the order of mega ohm (M Ω) is connected. GND 113 is 0V, and the space and components present around discharge electrode 120 and counter electrode 130 are also 0V. In addition, the current flowing through the discharge circuit by the discharge is in the microampere (μ a) level.
The discharge electrode 120 is an electrode that contributes to discharge generated based on a potential difference generated between the discharge electrode 120 and the counter electrode 130, and is disposed at a predetermined space from the counter electrode 130. The shape of the discharge electrode 120 is not particularly limited. In the present embodiment, the discharge electrode 120 is a rod-shaped member having conductivity, and has a portion tapered toward the counter electrode 130. A spherical portion 121 is disposed at an end portion of the discharge electrode 120 close to the counter electrode 130. The surface of the spherical portion 121 is a smooth surface to avoid generating a portion where electric charges are particularly concentrated.
The counter electrode 130 is an electrode disposed at a predetermined space from the discharge electrode 120, and attracts the charged particles 200 generated by the discharge by an electric field. The shape of the counter electrode 130 is not particularly limited. In the present embodiment, the counter electrode 130 is a plate-like member and includes a circular through hole 131 coaxial with the discharge electrode 120. That is, the spherical portions 121 of the discharge electrode 120 are arranged at equal distances from the peripheral portion of the through hole 131 of the counter electrode 130.
The water supply unit 140 supplies water to the tip of the discharge electrode 120. The water supply method of the water supply unit 140 is not particularly limited. Examples of the water supply method of the water supply unit 140 include the following methods: the water stored in the water storage part is supplied to the front end of the discharge electrode 120 by using a capillary phenomenon, or the water is pressurized and conveyed to the front end of the discharge electrode 120, or the water flows down or drops to the front end of the discharge electrode 120 by using gravity. In the case of the present embodiment, the water supply unit 140 is a cooling device that cools the discharge electrode 120, such as a peltier cell, and supplies water by cooling the discharge electrode 120 to the atmospheric temperature or lower to cause condensation of moisture in the air on the discharge electrode 120. In the case of the water supply unit 140, there is no need to store water in advance and there is no fear of water running out. In addition, regardless of the posture of the charged particle generating apparatus 100, water can be efficiently supplied to the discharge electrode 120.
Next, an operation example of the charged particle generating apparatus 100 according to the present embodiment will be described.
The discharge electrode 120 is cooled by the water supply unit 140, and dew condensation water is generated on the surface of the discharge electrode 120 in advance.
When a voltage of 4kV is applied between the discharge electrode 120 and the counter electrode 130 by the voltage applying unit 110, for example, the discharge electrode 120 is stabilized at a potential of-4 kV and the counter electrode 130 is stabilized at a potential of about-0.5 kV by a current flowing through a discharge circuit by discharge.
By the above-described discharge between the discharge electrode 120 and the counter electrode 130, the charged particles 200 including ions and charged corpuscle water are generated in the space between the discharge electrode 120 and the counter electrode 130. Here, the ion refers to an ion of an atom or molecule existing in the air. Specifically, the negative ions of OH are exemplified. The charged fine particulate water is formed by negatively charging nano-sized water droplets.
Specifically, the atoms and molecules in the air are ionized by the discharge between the discharge electrode 120 and the counter electrode 130. The water condensed on the surface of the discharge electrode 120 by the water supply unit 140 is drawn toward the counter electrode 130, and is collected on the surface of the spherical portion 121, thereby being charged. The charged water is atomized by electrostatic atomization, water sputtering, or the like to become charged fine particulate water, and is emitted from the discharge electrode 120. By the above operation, the charged particles 200 including ions and charged corpuscle water are generated.
In the case of this embodiment, both the discharge electrode 120 and the counter electrode 130 are negative electrodes, and the absolute value of the potential applied to the discharge electrode 120 is larger than the absolute value of the potential applied to the counter electrode 130. Therefore, the negatively charged particles 200 are repelled from the discharge electrode 120 and attracted by the counter electrode 130, and travel in space toward the counter electrode 130. When the charged particles 200 pass through the through-hole 131 of the counter electrode 130, the counter electrode 130 is also at a negative potential, and therefore, the charged particles are difficult to be captured by the counter electrode 130. With the above configuration, the negatively charged particles can be more efficiently emitted from the charged particle generating apparatus 100 to the outside.
In the case of emitting the positively charged particles 200, the discharge electrode 120 and the counter electrode 130 are set to a positive potential, whereby the positively charged particles can be efficiently emitted as described above.
Next, a hair care device including the charged particle generating device 100 will be described with reference to fig. 2. Fig. 2 is a sectional view showing a hair care device according to an embodiment.
The hair care device 300 includes a main body 301 and a grip 302. An air channel 311 is formed inside the main body 301. A blower 319 including a motor and a fan is disposed on the side of the intake port 312 in the air tunnel 311, and a heater 318 for heating an air flow generated by the blower 319 is disposed on the side of the discharge port 313.
A branching member 325 for forming a branching flow path 323 is disposed above the wind tunnel 311, and a branching flow for branching the air flow generated by the blower 319 flows through the branching flow path 323. The charged particle generating device 100 according to the present embodiment is disposed in the branch flow path 323.
A power switch 322 is provided on the outer surface of the grip portion 302, and a power supply line 324 connected to a commercial power supply is drawn from the distal end portion of the grip portion 302. A circuit unit 350 is disposed inside the grip portion 302. The circuit unit 350 converts the ac current received from the power supply line 324 into dc power suitable for the blower 319 and the heater 318, respectively, and supplies the dc power. Further, an external power supply 210 (see fig. 1) for supplying electric power to the circuit unit 350 and the charged particle generating device 100 is provided. The circuit unit 350 detects the operation of the power switch 322 by the user, and controls the operations of the blower 319, the heater 318, and the charged particle generating apparatus 100 in accordance with the operation contents. The electric circuit for supplying electric power to each component and controlling the operation may be integrated on one substrate or may be distributed over a plurality of substrates. The circuit unit 350 may be wired so that the surface of the grip portion 302 is set to a reference potential.
The basic operation of the hair care device 300 configured as described above will be described.
The user turns on the power switch 322 to supply power to the circuit unit 350 through the power line 324, and the circuit unit 350 is driven.
The driven circuit unit 350 supplies power to the voltage applying unit 110 and the water supply unit 140 of the charged particle generating apparatus 100. Thereby, the charged particles 200 are emitted from the charged particle generating apparatus 100.
In addition, electric power is supplied to the blower 319 to generate an air flow. A part of the air flow is heated by heater 318 to which electric power is supplied, and is blown out as warm air from discharge port 313 to the outside and supplied to the hair of the user. On the other hand, the surplus air flow passes through the branch flow path 323, pushes out the charged particles 200 emitted from the charged particle generator 100, and joins the warm air discharged from the discharge port 313 to supply the same to the hair of the user.
As described above, when the hair is dried, for example, negatively charged particles are emitted from the charged particle generating apparatus 100, and thereby the hair can be moistened and the smooth feeling of the hair can be improved. Further, by setting the grip portion 302 to the reference potential, it is possible to facilitate adhesion of the charged particles to the hair.
The present invention is not limited to the above embodiments. For example, another embodiment in which the constituent elements described in this specification are arbitrarily combined may be regarded as an embodiment of the present invention, and another embodiment in which some constituent elements are removed may be regarded as an embodiment of the present invention. Further, the present invention includes modifications that can be made by those skilled in the art to the above-described embodiments without departing from the scope of the present invention, that is, without departing from the meaning of the terms described in the claims.
For example, as shown in fig. 3, the voltage application unit 110 may receive electric power from a high-voltage external power supply 211 of high voltage and a relatively low-voltage constant-voltage power supply 212 with the reference potential (GND 113) in between, thereby realizing the potential relationship between the discharge electrode 120 and the counter electrode 130. This allows the potential relationship between the discharge electrode 120 and the counter electrode 130 to be arbitrarily changed.
The charged particle generating device according to the present invention can be applied to hair care devices such as a straight clip, in addition to the hair dryer described above. In addition, the present invention can be applied to air conditioning apparatuses such as coolers, air purifiers, dehumidifiers, humidifiers, and beauty treatment apparatuses such as beauty steamers and beauty treatment apparatuses.
