DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters or duplicate description of substantially the same configuration may be omitted.

[0010] It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0011] Hereinafter, a beauty device (hair care device 1) according to this embodiment will be described with reference to Figs. 1 to 3.

[0012] [1. Configuration] First, the configuration of a hair care device 1 according to this embodiment will be described.

[0013] The hair care device 1 according to this embodiment is an example of a beauty device, and in this embodiment, is a hair dryer.

[0014] As shown in Fig. 1, the hair care device 1 includes a main body 1a and a grip 1b. The main body 1a has a housing 2 that forms an outer shell, and a cavity 3 is formed within the housing 2. The cavity 3 has an air flow path 3a that extends from an intake port 4a on one side (the right side in Fig. 1) in the longitudinal direction (the left-right direction in Fig. 1) to an exhaust port 4b on the other side (the left side in Fig. 1).

[0015] A grip portion 1b, which is to be gripped by a user, is connected in a direction intersecting the longitudinal direction of the main body portion 1a to the lower portion of the housing 2. When the hair care device 1 is in use, the main body portion 1a and the grip portion 1b are configured to present an approximately T-shaped or approximately L-shaped appearance (in this embodiment, approximately T-shaped).

[0016] The grip part 1b has a base part 1c on the main body part 1a side and a tip part 1d. A slide-type power switch 5 is provided on the side of the grip part 1b, and a power cord 6 is drawn out from the protruding end part (tip part 1d) of the grip part 1b. The base part 1c is rotatably connected to the main body part 1a via a connecting part 1e. This allows the hair care device 1 to be folded up to a position where the tip part 1d is along the main body part 1a.

[0017] Furthermore, a fan 7 and a motor 8, which are an example of a blower, are disposed on the upstream side (the side closer to the inlet 4a) of the air blowing passage 3a in the main body 1a.

[0018] A heater 9, which is an example of a heating section that heats the air blown from the fan 7, is disposed downstream of the fan 7 (closer to the outlet 4b than the fan 7). The heater 9 is formed, for example, by winding a band-shaped corrugated electric resistor around the inner circumference of the air blowing flow path 3a.

[0019] Moreover, above (above) the air flow passage 3a, there is a branch flow passage 3b provided separately from the air flow passage 3a. Components of the spray device 10 and the charging unit 30 according to this embodiment are arranged in the branch flow passage 3b. Details of the configuration of the spray device 10 will be described later with reference to FIG. 2, and details of the configuration of the charging unit 30 will be described later with reference to FIG. 3.

[0020] In this embodiment, a control unit 20 that supplies power to and controls the operation of components that operate using electricity, such as the motor 8, heater 9, spray device 10, and charging unit 30, is disposed inside the grip 1b. Note that the electric circuits for supplying power to and controlling the operation of each component may be integrated on one board or distributed across multiple boards.

[0021] Next, the spray device 10 provided in the hair care device 1 configured as above will be described with reference to FIG.

[0022] 2, the spray device 10 has a tank 11 as a storage unit that stores liquid, a two-fluid nozzle 12 as a discharge unit that discharges atomized liquid, and a liquid delivery pump 13 that sends the liquid supplied from the tank 11 toward the two-fluid nozzle 12. The spray device 10 also has an air pump 15 connected to the two-fluid nozzle 12.

[0023] Although not shown, a liquid supply flow path to which liquid is supplied from the liquid delivery pump 13 and an air supply flow path to which air is supplied from the air pump 15 are formed inside the two-fluid nozzle 12.

[0024] Although not shown, a mixing space portion is formed inside the two-fluid nozzle 12 for mixing the liquid from the liquid supply passage with air from the air supply passage to atomize the liquid.

[0025] A liquid supply flow path inside the two-fluid nozzle 12 and the tank 11 are connected by a liquid tube 21, and a liquid feed pump 13 is disposed midway along the liquid tube 21.

[0026] The tank 11 is, for example, a bag-shaped container (pouch) made of a flexible laminate film. The liquid delivery pump 13 is, for example, a tube pump that delivers liquid by sandwiching a liquid tube 21 between a roller and a base portion.

[0027] On the other hand, an air supply passage inside the two-fluid nozzle 12 and the air pump 15 are connected by an air tube 22 .

[0028] The liquid (mist) that has been mixed and atomized in the mixing space inside the two-fluid nozzle 12 is then sprayed out of the two-fluid nozzle 12 from the mist outlet 12a (see FIG. 3).

[0029] Next, the charging unit 30 included in the hair care device 1 will be described with reference to FIG.

[0030] As shown in FIG. 3, the charging section 30 has a discharge electrode 31 connected to a high-voltage power supply, and a counter electrode 32 connected to a ground potential.

[0031] In this embodiment, the discharge electrode 31 is a needle-shaped electrode, and the counter electrode 32 is a ring-shaped electrode.

[0032] For example, a resistor is disposed in the electric circuit between the counter electrode 32 and the ground potential, and the counter electrode 32 has a potential between the ground potential and the high voltage potential applied to the discharge electrode 31. The potential of the counter electrode 32 is, for example, −500 V, and the high voltage potential applied to the discharge electrode 31 is, for example, −5 kV.

[0033] A mist outlet 12a of the two-fluid nozzle 12 is disposed in the vicinity (immediately adjacent) of the counter electrode 32. Further, with respect to the counter electrode 32, the mist outlet 12a of the two-fluid nozzle 12 is disposed downstream of the air flow that flows in the air blowing flow path 3a (on the side closer to the outlet 4b than the fan 7).

[0034] By arranging the counter electrode 32 and the two-fluid nozzle 12 in this manner, the electric charge and gas-phase ions generated by the discharge between the discharge electrode 31 and the counter electrode 32 are sprayed onto the mist that is released from the mist outlet 12a of the two-fluid nozzle 12 and before it diffuses.

[0035] The inner diameter of the counter electrode 32, which is a ring-shaped electrode, is equal to or smaller than the inner diameter of the mist outlet 12a of the two-fluid nozzle 12.

[0036] Furthermore, since the two-fluid nozzle 12 is positioned at an angle to the longitudinal axis La of the discharge electrode 31, the longitudinal axis La of the discharge electrode 31 intersects with the normal Lb to the opening surface of the mist outlet 12a.

[0037] [2. Operation] The basic operation of the hair care device 1 configured as above will now be described.

[0038] When a user turns on the sliding power switch 5, power is supplied to the control unit 20 via the power cord 6, and the control unit 20 is driven.

[0039] The driven control unit 20 passes current through a drive motor (liquid-feed pump drive motor) that drives the liquid-feed pump 13 and a drive motor (air pump drive motor) that drives the air pump 15. Supplying current to these drive motors causes the liquid in the tank 11 to be supplied to the bi-fluid nozzle 12, and air is supplied from the air pump 15 to the bi-fluid nozzle 12. As a result, the liquid is atomized in the bi-fluid nozzle 12 and is discharged from the bi-fluid nozzle 12 as a mist of a hair care agent containing oil, medicine, and the like.

[0040] When the power switch 5 is turned on, power is supplied to the motor 8 and the heater 9, and the motor 8 is driven to rotate, thereby rotating the fan 7 and forming an air flow. Specifically, the air that flows from the outside into the air flow passage 3a through the intake port 4a passes through the air flow passage 3a and is discharged to the outside from the outlet port 4b, forming an air flow. When power is supplied to the heater 9, the air blown by the fan 7 is heated and blown out as hot air from the hot air outlet port 4c to the outside and supplied to the user's hair. At this time, the mist discharged to the outside from the mist outlet port 4d is supplied to the user's hair on the air flow discharged to the outside from the outlet port 4b as described above.

[0041] Furthermore, by generating a discharge from the discharge electrode 31 of the charging unit 30 toward the counter electrode 32, electric charges and gas-phase ions are generated, and the generated electric charges and gas-phase ions pass through the counter electrode 32 and are released toward the mist outlet 4d.

[0042] By spraying the electric charge and gas-phase ions generated by the charging unit 30 onto the mist before it is diffused immediately adjacent to the two-fluid nozzle 12, the efficiently charged mist can be released from the mist outlet 4d toward the user's hair.

[0043] [3. Effects, etc.] The effects of this embodiment will be described below.

[0044] (1) A hair care device 1 includes a housing 2 having an inlet 4a and an outlet 4b, a charging unit 30 disposed inside the housing 2 and having a discharge electrode 31 and a counter electrode 32, and a spray device 10 having a two-fluid nozzle 12 that atomizes a liquid and discharges a mist. The two-fluid nozzle 12 is disposed in the vicinity (close to) the counter electrode so that the charge and gas-phase ions generated by the discharge between the discharge electrode 31 and the counter electrode 32 are sprayed onto the mist before it is released from the two-fluid nozzle 12 and diffuses.

[0045] Since the two-fluid nozzle 12 of the spray device 10 is disposed immediately adjacent to the counter electrode 32, the electric charge and gas-phase ions generated by the charging unit 30 are sprayed onto the mist before diffusion immediately adjacent to the two-fluid nozzle 12. Therefore, the mist sprayed from the two-fluid nozzle 12 can be efficiently charged, and the efficiently charged mist can be discharged from the mist outlet 4d to the outside of the hair care device 1 toward the user's hair.

[0046] According to the hair care device 1 of this embodiment, the mist can be efficiently charged, making the mist finer and improving the adhesion force due to electrostatic force, so that the mist can be more evenly and more evenly attached to the user's hair. In addition, among the gas phase ions generated by the charging unit 30, the gas phase ions that do not adhere to the mist are also released from the mist outlet 4d together with the mist and adhere to the user's hair. The gas phase ions themselves have the effect of improving the feel of the hair, so the effect on the hair can be more efficiently increased.

[0047] (2) The counter electrode 32 is made of a ring-shaped electrode having an inner diameter equal to or smaller than the inner diameter of the mist outlet 12a of the two-fluid nozzle 12.

[0048] Since the electric charges and gas phase ions passing through the opposing electrode 32 are converged to an area equal to or smaller than the area of ​​the mist outlet 12a, many of the electric charges and gas phase ions pass through the area where the mist is present, thereby enabling the mist to be charged more efficiently.

[0049] (3) The discharge electrode 31 is a needle-shaped electrode, and the two-fluid nozzle 12 is positioned at an angle to the longitudinal axis La of the discharge electrode 31 so that the longitudinal axis La of the discharge electrode 31 intersects with the normal Lb to the opening surface of the mist outlet 12a.

[0050] By increasing the overlap between the area where the charge and gas phase ions are emitted and the area where the mist is present, a greater proportion of the mist becomes charged before diffusing, and the mist can be charged more efficiently.

[0051] (4) The hair care device 1 includes an air blower that generates an air flow from the charging unit 30 toward the outlet 4b.

[0052] In addition to the ionic wind generated by the charging section 30, electric charges and gas-phase ions are released toward the mist outlet 4d by the airflow generated by the blowing section, thereby improving the rate at which the mist reaches and adheres to the user's hair.

[0053] (5) The two-fluid nozzle 12 is disposed downstream of the air flow with respect to the counter electrode 32 , and the counter electrode 32 has a potential between the ground potential and the high voltage potential applied to the discharge electrode 31 .

[0054] By charging the mist with the same sign as the potential applied to the counter electrode 32, a repulsive force is generated between the counter electrode 32 and the charged mist, thereby preventing the mist from flowing back toward the discharge electrode 31.

[0055] (Other embodiments) Hereinafter, modified examples of the arrangement of the charging section 30 and the two-fluid nozzle 12 will be described with reference to FIGS. 4A, 4B, 4C, and 4D.

[0056] The shape of the counter electrode 32 and the orientation of the mist outlet 12a of the two-fluid nozzle 12 are not limited to those in the above-described embodiment.

[0057] For example, in the embodiment shown in FIG. 4A, the two-fluid nozzle 12 is positioned at an angle of 90 degrees with respect to the longitudinal axis La of the discharge electrode 31 so that the longitudinal axis La of the discharge electrode 31 and the normal Lb to the opening surface of the mist outlet 12a are perpendicular to each other.

[0058] In the embodiment shown in FIG. 4B, the two-fluid nozzle 12 is disposed so that the longitudinal axis La of the discharge electrode 31 and the normal line Lb to the opening surface of the mist outlet 12a are parallel to each other.

[0059] In the embodiment shown in FIG. 4C, the counter electrode 32 is a plate- or rod-shaped electrode.

[0060] In the embodiment shown in Fig. 4D, the charging unit 30 is a charged fine water particle generator 40 that generates charged fine water particle. The charged fine water particle generator 40 has a cooling unit 41 that cools the discharge electrode 31, and can condense moisture in the air. As an example, the cooling unit 41 has a plurality of Peltier elements 42 (four in the illustrated example) and a heat sink 43, as shown in Fig. 4D.

[0061] In addition to the electric charge and gas phase ions, the charging unit 30 generates charged fine particle water, which has a greater effect on hair than the electric charge and gas phase ions, and the mist is charged with the charged fine particle water, the electric charge and the gas phase ions, thereby achieving a greater effect on the user's hair.

[0062] That is, the hair care device includes a discharge electrode connected to a high voltage power supply and a counter electrode connected to a ground potential, and includes a charging unit in which electric charges and ions generated by discharging from the discharge electrode toward the counter electrode pass near the counter electrode and are released toward a target object.The device has an atomizing unit that atomizes a liquid, and an outlet that releases the atomized mist from the atomizing unit is provided near the counter electrode, and the mist near the outlet is sprayed with electric charges and ions generated by the charging unit and released toward the target object.The aforementioned discharge electrode is a discharge electrode needle.The aforementioned discharge electrode needle is also oriented toward the target object.Furthermore, the aforementioned target object is hair.

[0063] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, and the like can be made within the scope of the claims or their equivalents. [Industrial Applicability]

[0064] The present disclosure is applicable to a beauty device equipped with a spray device, which efficiently charges the mist emitted from the discharge part of the spray device, thereby enabling the mist to be finer and the adhesion to be improved by electrostatic force. Specifically, the present disclosure is applicable to hair care devices, hair dryers, etc. [Explanation of symbols]
