Example 1
1 and 2 show a metal fine particle generator K of Example 1 of the present invention. The metal fine particle generator K includes a first electrode unit 1 to which a voltage is applied and a second electrode unit 2 connected to the ground and paired with the first electrode unit 1. Then, by discharging between the first electrode portion 1 and the second electrode portion 2, the finely divided metal is discharged from the first electrode portion 1. The metal fine particle generator K further includes an ion adsorption unit 3 for capturing a part of ions generated in the vicinity of the first electrode unit 1 by applying a voltage to the first electrode unit 1.

The first electrode portion 1 has a long and substantially cylindrical shape, one end of which is fixed to the electrode holder 4 and is connected to the first power source 6 via the lead wire 5. The first electrode portion 1 is made of metal. As this metal, transition metals such as gold, nickel, platinum, rhodium, palladium, silver, copper, and zinc are used. In particular, gold or platinum has an antioxidant effect. For this reason, if gold or platinum is used for the first electrode part 1, the finely divided gold or platinum is released from the first electrode part 1, and an antioxidative action by the fine particles is expected. Similarly, if silver or copper is used for the first electrode portion 1, an antibacterial effect is expected. Zinc is an essential element of the living body. For this reason, when zinc is used as the first electrode portion 1 and the finely divided zinc is allowed to act on the hair, it acts on the cuticle of the hair and an effect of preventing split ends is obtained. Similarly, a hair-growth effect is obtained when finely divided zinc is allowed to act on the scalp. Further, the first electrode portion 1 may not be composed of a single metal, but may be composed of two or more kinds of metals by plating, an alloy, or the like, so that the effects of the respective metals described above can be achieved simultaneously.

The second electrode portion 2 is made of a conductor and connected to the ground via a lead wire 5. Here, the conductor is, for example, a metal or conductive resin having a relatively low surface resistivity. The second electrode portion 2 has a flat plate shape, and a substantially circular opening is formed at a substantially central portion of the flat plate. The diameter of the opening is formed so as to be larger than the diameter of the circle appearing on the two surfaces at both ends of the elongated first electrode portion 1. The second electrode portion 2 has a flat plate surface that is perpendicular to the longitudinal direction of the first electrode portion 1, and the flat plate surface is opposite to the side fixed to the electrode holder 4 of the first electrode portion 1. It is arranged so as to face the tip of the side with a certain distance, and is fixed to the electrode holder 4. At this time, the opening of the second electrode portion 2 is located in front of the first electrode portion 1 in the longitudinal direction. Then, the metal atomized from the first electrode portion 1 passes through the opening formed in the second electrode portion 2.

The ion adsorbing portion 3 is composed of a pair of flat conductors. Here, the conductor is, for example, a metal or conductive resin having a relatively low surface resistivity. The ion adsorbing portion 3 is a front side where the direction of the flat plate surface of the flat conductor and the longitudinal direction of the first electrode portion 1 substantially coincide with each other, and fine metal particles are discharged from the first electrode portion 1. The second electrode portion 2 is disposed on the side opposite to the first electrode portion 1 so as to be located outside the first electrode portion 1 and is fixed to the electrode holder 4. That is, the pair of conductors of the ion adsorbing part 3 are arranged in the vicinity of the second electrode part 2 so as to face each other and sandwich the opening formed in the second electrode part 2.

Next, the operation when a high voltage is applied to the first electrode unit 1 by the first power source 6 will be described. When a high voltage is applied to the first electrode portion 1, a discharge is generated between the first electrode portion 1 and the second electrode portion 2. Then, the finely divided metal is released from the first electrode portion 1. The finely divided metal released at this time moves through the opening formed in the second electrode portion 2 in the direction of the ion adsorption portion 3. Further, when a high voltage is applied to the first electrode portion 1, ions are generated in the vicinity of the first electrode portion 1. At this time, the ions move in the direction of the ion adsorbing portion 3 through the opening formed in the second electrode portion 2, like the finely divided metal. Ions that have passed through the opening of the second electrode portion 2 are captured by the ion adsorption portion 3 made of a conductor. Therefore, according to the metal fine particle generating apparatus K of Example 1, since the ion adsorbing unit 3 is provided, it is possible to capture a part of the generated ions and control the amount of ions. Further, the ion adsorbing part 3 is arranged on the front side from which the metal atomized from the first electrode part 1 is released, that is, on the opposite side of the second electrode part 2 to the first electrode part 1. For this reason, ions can be captured by the ion adsorbing unit 3 on the front side from which fine metal is released.

In Example 1 described above, a pair of flat conductors are disposed as the ion adsorbing unit 3. However, the ion adsorbing unit 3 is surrounded by the first electrode unit 1 from which the metal atomized is released. You may arrange as follows. That is, you may make it surround the front of the 1st electrode part 1 by arrange | positioning the several flat conductor. As shown in FIGS. 3 and 4, the ion adsorption portion 3 may be formed in a frame shape so as to surround the front of the first electrode portion 1. Thus, by arranging the ion adsorbing part 3 so as to surround the front of the first electrode part 1, the area of the ion adsorbing part 3 is increased and is generated radially from the first electrode part 1 to the front. Ions to be captured can be captured more efficiently by the ion adsorption unit 3.

(Example 2)
Next, Example 2 will be described with reference to FIG. In addition, about the structure similar to the metal microparticle production | generation apparatus K of Example 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted. In the metal fine particle generator K of Example 2, the ion adsorbing unit 3 is connected to the ground via the lead wire 5.

Therefore, since the charges due to the ions trapped by the ion adsorbing unit 3 are released to the ground, the ion adsorbing unit 3 is charged by the trapped ions, and the ion trapping efficiency by the ion adsorbing unit 3 can be prevented from being lowered.

(Example 3)
Next, Example 3 will be described with reference to FIG. In addition, about the structure similar to the metal microparticle production | generation apparatus K of Example 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted. The ion adsorption part 3 of Example 3 is comprised by a pair of

3rd electrode parts

3a and 3b. One side 3 a of the third electrode portion is connected to the ground via the lead wire 5. The other side 3 b of the third electrode portion is connected to the second power source 7 via the lead wire 5. In this case, when the second power source 7 applies a voltage to the other side 3b of the third electrode portion, a potential difference is generated between the pair of

third electrode portions

3a and 3b. Then, since an electric field is generated between the

third electrode portions

3a and 3b, the generated ions are attracted. As a result, ions can be trapped more efficiently by the

third electrode portions

3a and 3b, which are the ion adsorption portions 3.

Next, Example 4 will be described based on FIGS. In addition, Example 4 demonstrates based on the metal microparticle production | generation apparatus K of the said Example 3, The same code | symbol is attached | subjected about the structure similar to the metal microparticle production | generation apparatus K of Example 3, and the description is given. Omitted.

third electrode portions

3a and 3b, and a first current corresponding to the current detected by the ammeter 20. And a control unit 21 for controlling a voltage applied to the

third electrode units

third electrode portions

3a and 3b are composed of a pair of electrode portions. One side 3 a of the third electrode portion is connected to the ground via the lead wire 5. The other side 3 b of the third electrode portion is connected to the ammeter 20 and the second power source 7 via the lead wire 5.

The ammeter 20 is composed of an existing ammeter, and is inserted between the other side 3b of the third electrode portion and the second power source 7, and is connected to each through a lead wire 5. Further, the ammeter 20 is also connected to the control unit 21 via the lead wire 5. The second power source 7 is connected to the ammeter 20 via the lead wire 5 and is also connected to the control unit 21 via the lead wire 5. The control unit 21 includes a current value reading unit 22 and a voltage control unit 23. The current value reading unit 22 is connected to the ammeter 20 and the first power source 6 via the lead wire 5, and automatically acquires the measured value of the current measured by the ammeter 20, and the acquired measured current value Is output. The voltage control unit 23 acquires the measured current value output from the current value reading unit 22, compares the measured current value with the set current value preset and stored therein, and the measured current value becomes the set current value. Thus, the voltage of the second power supply 7 is varied.

In Example 4, ions generated near the first electrode portion 1 are captured by the

third electrode portions

3a and 3b. Then, the

third electrode portions

3a and 3b are charged by the trapped ions. When the

third electrode portions

3a and 3b are charged, a current flows through the lead wire 5 connected to the

third electrode portions

3a and 3b. This current is detected by the ammeter 20 as a measured current value. At this time, if the amount of ions captured by the

third electrode portions

3a and 3b is small, the measured current value measured by the ammeter 20 decreases. Then, the control unit 21 increases the voltage applied to the second power supply 7 so that the decreased measured current value becomes the set current value, captures more ions, and matches the measured current value with the set current value. To control. On the other hand, when the amount of ions captured by the

third electrode portions

3a and 3b is large, the measured current value measured by the ammeter 20 increases. Then, the control unit 21 performs control to lower the voltage applied to the second power source 7 so that the increased measured current value becomes the set current value, and to match the measured current value and the set current value. Thus, the control unit 21 controls the second power supply 7 so that the measured current value becomes a preset set current value, so that the

third electrode units

3a and 3b generate the amount of ions generated. Depending on the, ions can be trapped.

(Example 5)
Next, Example 5 will be described based on FIGS. In addition, Example 5 demonstrates based on the metal microparticle production | generation apparatus K of the said Example 3, The same code | symbol is attached | subjected about the structure similar to the metal microparticle production | generation apparatus K of Example 3, and the description is given. Omitted.

The metal fine particle generator K of Example 5 controls the voltage applied to the ion detector 30 for detecting the amount of ions in the vicinity of the

third electrodes

3a and 3b and the other side 3b of the third electrode. And a control unit 31 for performing the operation. The control unit 31 controls the voltage applied to the other side 3 b of the third electrode unit by the second power source 7 in accordance with the amount of ions detected by the ion detection unit 30. The

third electrode portions

3a and 3b are composed of a pair of electrode portions. One side 3 a of the third electrode portion is connected to the ground via the lead wire 5. The other 3 b of the third electrode portion is connected to the second power source 7 via the lead wire 5. The ion detector 30 induces and outputs a static voltage based on the same principle as electrostatic induction, and can measure the amount of ions in a non-contact manner. The ion detection unit 30 is disposed in front of the first electrode unit 1 and in the vicinity of the

third electrode units

3a and 3b.

The control unit 31 is connected to the ion detection unit 30 and the second power source 7 via the lead wire 5. The control unit 31 includes an ion amount reading unit 32 and a voltage control unit 33. The ion amount reading unit 32 automatically acquires the measurement ion amount measured by the ion detection unit 30 and outputs the acquired measurement ion amount. The voltage control unit 33 acquires the measured ion amount output from the ion amount reading unit 32, compares the set ion amount preset and stored therein with the measured ion amount, and the measured ion amount is set to the set ion amount. The second power source 7 is varied so that

In the metal fine particle generator K of Example 5, when the measured ion amount measured by the ion detector 30 is larger than the set ion amount, the control unit 31 increases the voltage applied to the second power source 7 to increase the voltage. Control is performed so that many ions are captured and the measured ion amount matches the set ion amount. On the other hand, when the measured ion amount measured by the ion detector 30 is smaller than the set ion amount, the controller 31 lowers the voltage applied to the second power source 7 and decreases the ion trapping amount to measure ions. The amount is controlled so as to match the set ion amount. Therefore, the control unit 31 controls the potential difference between the pair of

third electrode units

3a and 3b by the second power source 7 in accordance with the amount of ions detected by the ion detection unit 30, so that the third electrode The ions generated by the

portions

(Example 6)
Next, Example 6 will be described with reference to FIGS. In addition, Example 6 demonstrates based on the metal microparticle production | generation apparatus K of the said Example 3, The same code | symbol is attached | subjected about the structure similar to the metal microparticle production | generation apparatus K of Example 3, and the description is given. Omitted.

The metal fine particle generating apparatus K of Example 6 applies the metal fine particle detection unit 40 for detecting the amount of fine metal particles in the vicinity of the

third electrode units

3a and 3b and the other side 3b of the third electrode unit. And a control unit 41 for controlling the voltage. The control unit 41 controls the voltage applied to the other side 3b of the third electrode unit by the second power source 7 in accordance with the amount of metal atomized by the metal particle detection unit 40. The

third electrode portions

3a and 3b are composed of a pair of electrode portions. One side 3 a of the third electrode portion is connected to the ground via the lead wire 5. The other side 3 b of the third electrode portion is connected to the second power source 7 via the lead wire 5. The metal fine particle detection unit 40 electrostatically collects the finely divided metal in the crystal resonator, and detects the amount of the finely divided metal from the change of the crystal resonator. The metal fine particle detection unit 40 is disposed in front of the first electrode unit 1 and in the vicinity of the

third electrode units

3a and 3b. In addition to the above-mentioned method, the metal fine particle detection unit 40 quantifies the metal. For example, the metal fine particle detection unit 40 applies light of a specific wavelength, laser, or radiation to the finely divided metal to emit fluorescence emitted from the finely divided metal. There may be used a method of quantifying the metal atomized by quantifying the scattering intensity, or a method of introducing the metal atomized into a specific solvent and applying light to measure the absorbance.

The control unit 41 is connected to the metal fine particle detection unit 40 and the second power source 7 via the lead wire 5. The control unit 41 includes a metal fine particle amount reading unit 42 and a voltage control unit 43 for changing the second power source 7. The metal fine particle amount reading unit 42 automatically acquires the amount of fine metal particles measured by the metal fine particle detection unit 40 and outputs the acquired measured metal fine particle amount. The voltage control unit 43 obtains the measured metal fine particle amount output from the metal fine particle amount reading unit 42, and compares the reference metal fine particle amount preset in the inside with the measured metal fine particle amount. When the measured metal fine particle amount is larger than the reference metal fine particle amount, the voltage controller 43 increases the voltage applied by the second power source 7. When the measured metal fine particle amount is smaller than the reference metal fine particle amount, the voltage controller 43 decreases the voltage applied by the second power source 7.

Here, when the voltage applied to the first electrode portion 1 is increased, the amount of finely divided metal emitted from the first electrode portion 1 is increased and is generated in the vicinity of the first electrode portion 1. The amount of ions also increases.

Therefore, in the metal fine particle generating apparatus K of Example 6, it is considered that many ions are generated when the measured metal fine particle amount measured by the metal fine particle detector 40 is larger than the reference metal fine particle amount. In this case, the control unit 41 increases the voltage applied to the second power supply 7 to capture more ions. On the other hand, when the amount of the measured metal fine particles measured by the metal fine particle detector 40 is smaller than the reference metal fine particle amount, the control unit 41 lowers the voltage applied to the second power source 7 and decreases the ion trapping amount.

Therefore, in the sixth embodiment, the control unit 41 is applied between the

third electrode units

3a and 3b by the second power source 7 in accordance with the amount of the metal atomized by the metal particle detection unit 40. Control the potential difference. Thus, the

third electrode parts

3a and 3b can capture the generated ions.

(Example 7)
Next, based on FIG. 13, the hair care apparatus of Example 7 is demonstrated. The hair care device of Example 7 is a hair dryer equipped with the metal fine particle generator K described in Examples 1-6 above. However, the usage application of the metal fine particle generation device K is not limited to a hair dryer, and may be a hair care device such as a hair iron or a hair brush.

The hair dryer of Example 7 includes a body case 53 in which an air inlet 51 and an outlet 52 are arranged as shown in FIG. Inside the main body case 53, a blower 54 that discharges air sucked from the suction port 51 from the discharge port 52 and a superheater 55 that superheats air downstream of the blower 54 are provided. In a predetermined place of the main body case 53, a metal fine particle generation device K, a fine particle flow channel 57 through which the fine metal generated in the metal fine particle generation device K flows, and a fine particle discharge port 58 for discharging the fine metal are provided. Then, an introduction path 59 for introducing air from the blower 54 to the fine particle flow path 57 is provided. With such a configuration, fine particles are discharged from the fine particle discharge port 58 by the air into which the metal has been introduced.

In addition, the air blowing unit 54 includes a motor 60 and a fan 61 connected to the motor 60. A cover 67 is provided on the downstream side of the heating unit 55 and on the upper side of the main body case 53. In the cover 67, a metal fine particle generating device K is accommodated. On the downstream side of the metal fine particle generation device K, a fine particle flow channel 57 through which the metal atomized by the metal fine particle generation device K flows is formed. A fine particle discharge port 58 through which the atomized metal is discharged is provided at the tip of the fine particle flow path 57. The metal particulate generator K is arranged so that the first electrode portion 1 is located on the introduction path 59 side and the second electrode portion 2 is located on the particulate discharge port 58 side.

A handle portion 63 that is gripped by the user is provided below the main body case 53. A control unit 64 is disposed in the handle unit 63. A power cord 65 that supplies power for applying a high voltage to the metal particulate generator K is connected to the controller 64. A switch 66 is provided on the side of the control unit 64 for the user to operate the hair dryer to drive or stop.

Next, the operation of the hair dryer of Example 7 will be described. When the user grasps the handle portion 63 provided on the lower side of the main body case 53 and operates the switch 66, the motor 60 is driven in the blower portion 54, and the fan 61 connected to the motor 60 rotates. When the fan 61 rotates, air is sucked from the suction port 51, and the sucked air passes through the superheater 55 provided on the downstream side of the blower 54. Here, when the switch 66 is further operated, the heater 62 in the superheater 55 is driven. For this reason, the air passing through the superheated portion 55 is superheated, then flows through the air flow path 68 and is discharged from the discharge port 52 to the outside.

A part of the air flowing through the air flow path 68 is introduced into the introduction path 59 provided at the upper part of the main body case 53 and passes through the metal fine particle generation device K arranged in the cover 67. Here, when the switch 66 is further operated, a high voltage is applied by the first power source 6 to the first electrode unit 1 disposed in the metal fine particle generating apparatus K. For this reason, a discharge is formed between the first electrode part 1 and the second electrode part 2. When the discharge is formed, a part of the first electrode portion 1 made of metal is made fine particles by the energy of the discharge. As a result, fine metal particles are released from the first electrode portion 1 and ions are generated in the vicinity of the first electrode portion 1. The finely divided metal and ions pass through the fine particle passage 57 together with the air introduced from the introduction passage 59, and then are discharged from the fine particle discharge port 58 and supplied to the hair. However, some of the generated ions are captured by the ion adsorbing unit 3 of the metal fine particle generator K, and after excess ions are removed, the ions are supplied to the hair. Therefore, according to the hair dryer of Example 7, the metal microparticulated can be made to act on hair, an excess ion can be removed, and an appropriate quantity of ion can be supplied to hair. As a result, the user can suppress the spread of the hair due to ions and obtain a moist and coherent hair state.
