Description

[Technical field]

[0001] The present invention relates to a spray for skin or hair, a cosmetic treatment method and a spray device. [Background technology]

[0002] Conventionally, there has been proposed a device that includes a liquid agent spraying mechanism that electrostatically atomizes and sprays the liquid agent, and a mist generating mechanism that generates mist, and that sprays the liquid agent with the mist, the particle size of which has been reduced by electrostatic atomization. For example, in the device of Patent Document 1, the liquid agent spraying port of the liquid agent spraying mechanism and the mist discharge port of the mist generating mechanism are separately provided, and the liquid agent spraying mechanism and the mist generating mechanism are controlled to spray simultaneously. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2010-172659 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, when the liquid agent or water particles are charged by electrostatic atomization or the like as in the above-mentioned device, they may be electrically attracted to the surface of the stratum corneum of the skin, making it difficult for them to penetrate into the stratum corneum. Also, in a device in which the liquid agent spray nozzle and the mist discharge nozzle are provided separately, it may be difficult to uniformly mix the sprayed liquid agent and mist.

[0005] The main object of the present invention is to more appropriately improve the permeability of an active ingredient when the spray is sprayed onto the skin or hair. [Means for solving the problem]

[0006] In order to achieve the above-mentioned main object, the present invention adopts the following means.

[0007] The spray of the present invention comprises A spray for skin or hair, comprising: Atomized medicine containing a specified active ingredient is mixed with fine water with a particle size of 50 nanometers or less. The gist of the present invention is as follows.

[0008] The spray of the present invention is a mixture of an atomized drug and fine water with a particle size of 50 nanometers or less. When this spray is sprayed onto skin or hair, the fine water penetrates into the skin or hair, contributing to maintaining moisture while forming a route for the active ingredient to penetrate and promoting penetration, so that the permeability of the active ingredient can be improved more appropriately. In addition, since the fine water is a particle with no electric charge, that is, it is uncharged, it can penetrate into the stratum corneum without being electrically attracted to the surface of the stratum corneum of the skin. Furthermore, the gaps in the stratum corneum of the skin are said to be about 20 to 50 nanometers or less, and the particle size of the fine water is 50 nanometers or less, so that it can easily enter the gaps in the stratum corneum, which is also the reason for the high penetration effect.

[0009] The cosmetic treatment method of the present invention includes a spraying step of spraying a mist of a medicine containing a specific active ingredient and fine water having a particle size of 50 nanometers or less onto the skin or hair. Therefore, it is possible to more appropriately improve the permeability of the active ingredient when the spray is sprayed onto the skin or hair.

[0010] The cosmetic treatment method of the present invention may include a mixing step of mixing the atomized drug and the fine water, and in the spraying step, the spray obtained by mixing the atomized drug and the fine water in the mixing step may be sprayed toward the skin or hair. In this way, the atomized drug and the fine water can be sprayed in a sufficiently mixed state compared to spraying them separately, so that uneven spraying can be prevented and the penetration of the active ingredient can be further appropriately improved. In addition, the mixing amount (ratio) of the atomized drug and the fine water can be easily adjusted.

[0011] The spray device of the present invention comprises: an atomizing unit that generates an atomized medicine by atomizing a medicine containing a predetermined active ingredient; A fine water generating section that changes between a moisture absorbing state in which moisture in the air is adsorbed to a conductive polymer film as a temperature drop and a moisture releasing state in which the moisture adsorbed to the conductive polymer film is released as fine water particles having a particle size of 50 nanometers or less as a temperature rise; A spray unit that sprays the atomized medicine and the fine water toward the skin or hair; The gist of the project is to provide the following:

[0012] In the spray device of the present invention, the atomized medicine generated in the atomizing section and the fine water discharged by changing the fine water generating section between a moisture absorbing state and a moisture releasing state are sprayed from the spray section toward the skin or hair. Therefore, the permeability of the active ingredient when the spray is sprayed on the skin or hair can be more appropriately improved.

[0013] The spray device of the present invention may be provided with a mixing section that communicates with the atomizing section, the fine water generating section, and the spray section and mixes the atomized medicine with the fine water, and the spray section may spray the spray in which the atomized medicine and the fine water are mixed in the mixing section. In this way, the mixing ratio of the atomized medicine and the fine water can be easily adjusted compared to a case where they are sprayed separately, and therefore the permeability of the active ingredient can be further appropriately improved.

[0014] The spray device further includes a mixing section communicating with the atomizing section, the fine water generating section, and the spray section, and mixing the atomized medicine with the fine water; a control section that repeats a moisture absorption state in which the air outside the mixing section is supplied to the conductive polymer membrane whose temperature is lowered while sealing the mixing section, and a moisture release state in which the air in the mixing section is circulated through the conductive polymer membrane whose temperature is raised, and the moisture adsorbed on the conductive polymer membrane is released into the mixing section as fine water having a particle size of 50 nanometers or less; and a control section that controls to increase the concentration of the fine water in the mixing section. The spray section may be configured to spray a spray in which the atomized medicine and the fine water are mixed in the mixing section. In this way, the fine water and the atomized medicine can be mixed in a state in which the concentration of the fine water in the mixing section is increased. Therefore, the spray in which the fine water is sufficiently mixed can be sprayed, and the permeability of the active ingredient can be further improved while enhancing the moisturizing effect.

[0016] [First embodiment] Next, a first embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a schematic diagram showing the configuration of a cosmetic treatment device 1, Fig. 2 is a schematic diagram showing the configuration of a spray device 10, and Fig. 3 is a schematic diagram showing the configuration of a fine water generating cartridge 30.

[0017] As shown in FIG. 1, the cosmetic treatment device 1 includes a device body 2 that houses a spray device 10, a discharge head 4 that discharges the spray generated by the spray device 10, a movable arm 5 to which the discharge head 4 is attached at its tip, and a support section 6 that supports the base end of the movable arm 5 on the device body 2. The device body 2 is supported movably by casters 3 attached to the bottom. The movable arm 5 has a supply path for the spray to the discharge head 4 formed inside the arm, the discharge head 4 is rotatably attached to its tip, and the base end is rotatably supported by the support section 6. Therefore, the discharge head 4 can move and rotate in the up-down, left-right, and front-back directions relative to the device body 2, and can be adjusted to a position suitable for the treatment subject. This cosmetic treatment device 1 is placed, for example, in an esthetic salon or a beauty salon, or may be placed in an individual's home.

[0018] As shown in FIG. 2, the spray device 10 includes a mixing tank 12, a fine water supply unit 20, a medicine atomization unit 40, and a spray unit 50.

[0019] The mixing tank 12 is configured in a rectangular parallelepiped or cylindrical shape, and includes a mixing fan 14 therein, and the fine water supply unit 20, the medicine atomizing unit 40, and the spray unit 50 are attached so as to communicate with the inside of the tank. The mixing fan 14 is arranged so as to generate a swirling flow in the mixing tank 12 by blowing air. The mixing tank 12 also includes a first opening / closing damper 16 that switches between communication and blocking between the fine water supply unit 20 and the inside of the tank by opening / closing operation, a second opening / closing damper 17 that switches between communication and blocking between the medicine atomizing unit 40 and the inside of the tank by opening / closing operation, and a third opening / closing damper 18 that switches between communication and blocking between the spray unit 50 and the inside of the tank by opening / closing operation. The first to third opening / closing dampers 16 to 18 are all opened and closed by operating the opening / closing plates driven by a motor (not shown).

[0020] The fine water supply unit 20 includes a duct 21 having an air passage 22 formed therein, a fine water generating cartridge 30, an electrical circuit 35, and a supply fan 36.

[0021] The duct 21 is a cylindrical member with both ends open, and has an intake port 21a that opens outside the mixing tank 12 and a communication port 21b that communicates with the mixing tank 12 and is opened and closed by the first opening and closing damper 16, forming a linear air passage 22. The fine water generating cartridge 30 and the supply fan 36 are arranged in the air passage 22 in the order of the supply fan 36 and the fine water generating cartridge 30 from the intake port 21a side.

[0022] 3, the fine water generating cartridge 30 includes a cylindrical case 32 having an outer diameter that allows it to be placed in the air passage 22, and a fine water generating element 34 provided in the case 32. The fine water generating element 34 includes a base material 34a and a conductive polymer film 34b formed on the surface of the base material 34a.

[0023] The substrate 34a is formed of a conductive material such as a metal material such as stainless steel metal or copper metal, a carbon material, or a conductive ceramic material. In this embodiment, a metal foil of stainless steel to which aluminum is added is used. The fine water generating element 34 is formed in a corrugated, honeycomb, or spiral shape so that air can flow through it and the surface area of ​​the substrate 34a (conductive polymer film 34b) is as large as possible. A current-carrying circuit 35 including a power source and a switch is connected to the substrate 34a. When the control unit 60 turns on the switch of the current-carrying circuit 35, the current-carrying circuit 35 is in a current-carrying state in which current is applied to the substrate 34a, and when the control unit 60 turns off the switch, the current-carrying circuit 35 is in a non-current-carrying state in which current is cut off to the substrate 34a.

[0024] The conductive polymer film 34b is formed of a polymer compound having conductivity such as a thiophene-based conductive polymer. In this embodiment, it is formed of PEDOT / PSS (poly(3,4-ethylenedioxythiophene) / poly(styrenesulfonic acid)) among thiophene-based conductive polymers. PEDOT / PSS has a structure in which PEDOT is dispersed in PSS having a sulfonic acid group, which is an acidic functional group capable of hydrogen bonding. In addition, a nanochannel, which is a nanometer-sized flow path of about 2 nanometers (nm), is formed at the boundary between PEDOT and PSS. Since many sulfonic acid groups exist in this nanochannel, when the moisture content on the surface is high and the moisture content inside is low, the moisture present on the surface of the conductive polymer film 34b moves to the inside through the sulfonic acid groups in the nanochannel due to the concentration difference between the surface and the inside. This allows the conductive polymer film 34b to adsorb moisture. In addition, when the moisture content on the surface is low and the moisture content inside is high with moisture adsorbed inside, the moisture moves to the surface through the sulfonic acid groups in the nanochannel due to the concentration difference between the surface and the inside. As a result, moisture is released from the conductive polymer film 34b as fine water. In addition, when the temperature of the conductive polymer film 34b is increased, the moisture (fine water) is released more quickly than when the moisture moves due to only the concentration difference, and when the temperature of the conductive polymer film 34b is decreased, the moisture is adsorbed more quickly than when the moisture moves due to only the concentration difference. In this way, the fine water generating cartridge 30 (fine water generating element 34) changes to a hygroscopic state in which the conductive polymer film 34b adsorbs moisture in the air as the temperature decreases, and changes to a hygroscopic state in which the conductive polymer film 34b releases the adsorbed moisture as the temperature increases. The thickness of the conductive polymer film 34b can be appropriately determined according to the required amount of adsorption (release) of fine water. For example, when the conductive polymer film 34b is formed to have a thickness of 1 to 30 micrometers, it can adsorb enough moisture to release fine water in a time of several seconds to several tens of seconds.

[0025] In addition, the fine water generating cartridge 30 emits uncharged fine water with a particle size of 50 nanometers or less, for example, a particle size of about 1 to 2 nanometers, from the conductive polymer membrane 34b of the fine water generating element 34. The reason for such particle size is thought to be that the size of the nanochannel is 2 nanometers or less, and therefore the water in the nanochannel is improved in motility due to the temperature rise of the conductive polymer membrane, and the pressure rise causes water to fly out of the nanochannel. Even if the water particles aggregate after flying out, the particle size is distributed in the range of 50 nanometers or less. A detailed description of the fine water generation of such a fine water generating cartridge 30 (conductive polymer membrane 34b) is described in WO2020 / 054100 and JP2019-018195A of the applicant of the present application, and therefore further detailed description will be omitted.

[0026] The supply fan 36 is driven to rotate in a predetermined direction to send air from the intake port 21a outside the mixing tank 12 toward the inside of the mixing tank 12 (communication port 21b). Therefore, air sucked into the air passage 22 can be sent into the mixing tank 12 through the fine water generating cartridge 30. The supply fan 36 is driven to rotate by a motor (not shown), and is controlled by the control unit 60 through PWM (Pulse Width Modulation) control or voltage control. The supply fan 36 may be a propeller fan, a sirocco fan, or the like.

[0027] The medicine nebulization unit 40 includes a medicine tank 42 that contains medicine D, and a nebulization section 44 that nebulizes the medicine D contained in the medicine tank 42 and supplies the nebulized medicine D from a supply port 45 into the mixing tank 12. The nebulization section 44 is configured to nebulize the medicine D by, for example, an ultrasonic nebulization method that nebulizes the medicine D by vibration of a piezoelectric element. The nebulization section 44 may be configured to nebulize the medicine D by other methods such as an air spray method, an electrostatic nebulization method, or a centrifugal nebulization method. The supply port 45 is opened and closed by a second opening / closing damper 17.

[0028] The medicine D contained in the medicine tank 42 contains a mixture of beauty ingredients and medicinal ingredients as a predetermined active ingredient. Examples of the medicine D and the active ingredient include, but are not limited to, moisturizing ingredients, herbal extracts, enzymes such as tyrosinase, superoxide dismutase, and lipase, vitamins and derivatives thereof such as retinol, ascorbic acid, tocopherol, pyridoxal, and riboflavin, organic pigments such as β-carotene and chlorophyll, moisturizing ingredients such as glycerin, sorbitol, urea, lactic acid, propylene glycol, polyethylene glycol and copolymers, glucose derivatives, and the like, emollient ingredients such as paraffin, stearyl alcohol, cetyl alcohol, squalane, silicone oil, and stearyl, and the like, treatment ingredients, dandruff suppressing ingredients, hair nourishing ingredients, and hair growth ingredients.

[0029] The spray unit 50 includes a duct 51 in which an air passage 52 is formed, and a spray fan 54. The duct 51 is a cylindrical member with both ends open, and has a spray port 51a that opens outside the mixing tank 12, and a communication port 51b that communicates with the mixing tank 12 and is opened and closed by the third opening and closing damper 18. The duct 51 is formed in a tapered shape so that the cross-sectional area of ​​the air passage 52 becomes smaller toward the spray port 51a side than the spray fan 54. The spray unit 50 takes in the spray agent in the mixing tank 12 by operating the spray fan 54 and sprays it from the spray port 51a. The spray agent sprayed from the spray port 51a reaches the discharge head 4 through a supply path in the movable arm 5.

[0030] The control unit 60 is configured as a microprocessor with a CPU as its core, and is equipped with a ROM, a RAM, and an input / output port in addition to the CPU. An operation signal from a start switch 62 for starting the operation of the spray device 10, an operation signal from an air volume adjustment switch 64 for adjusting the air volume of each fan 14, 36, 54 individually or collectively, and the like are input to the control unit 60 via the input port. In addition, the control unit 60 outputs a drive signal to a motor for rotating each fan 14, 36, 54, a drive signal to the first to third opening / closing dampers 16 to 18, a drive signal to a switch of the current supply circuit 35, and the like via the output port.

[0031] Next, a cosmetic treatment method in which the cosmetic treatment device 1 (spray device 10) configured in this manner is used to spray the spray onto the skin and hair will be described. FIG. 4 is a process diagram showing an example of the cosmetic treatment method. A practitioner (salonist) at an esthetic salon or the like supplies (stores) a drug D containing an active ingredient in the drug tank 42 of the drug atomization unit 40 (step S100). Next, the practitioner adjusts the position and orientation of the discharge head 4 so that the discharge head 4 can discharge the spray toward the target spray area of ​​the patient (step S110), and operates the start switch 62 to perform the spraying process using the spray device 10 (step S111). 2 0). By this spraying process, the spray produced by the spray device 10 is discharged from the discharge head 4 and sprayed onto the skin and hair of the person to be treated.

[0032] FIG. 5 is a process diagram showing an example of the spraying process. In the spraying process, the control unit 60 of the spray device 10 switches the first opening / closing damper 16 and the second opening / closing damper 17 to an open state and closes the third opening / closing damper 18 to switch to a supply state of fine water and atomized medicine (S200). In this supply state, the fine water generating cartridge 30 is turned on to drive the supply fan 36 in a predetermined rotational direction to supply fine water into the mixing chamber 12 by moisture release control (S210), and the medicine atomization unit 40 is operated to supply the atomized medicine into the mixing chamber 12 (S220), and a predetermined supply time is waited for to elapse (S230). In S210, the supply fan 36 is driven to rotate in the predetermined rotational direction, so that air sucked in from the intake port 21a is discharged from the communication port 21b into the mixing chamber 12 (FIG. 2 (See dotted arrow in ). In addition, since the power supply to the fine water generating cartridge 30 is turned on, the temperature of the conductive polymer film 34b rises, and the release of fine water is promoted. If the spraying process is started in a state where no moisture is adsorbed to the conductive polymer film 34b, before S210, the power supply to the fine water generating cartridge 30 is turned off and the supply fan 36 is driven to perform moisture absorption control to adsorb moisture to the conductive polymer film 34b.

[0033] When the control unit 60 determines in S230 that the supply time has elapsed, it switches to a mixed state of the fine water and the atomized medicine by closing all of the first opening and closing damper 16, the second opening and closing damper 17, and the third opening and closing damper 18 (S240). In this mixed state, the mixing fan 14 is operated to mix the fine water and the atomized medicine in the mixing tank 12 (S250), and a predetermined mixing time is waited for to elapse (S260). The operation of the mixing fan 14 creates an air flow in the mixing tank 12 (see the dotted arrow in FIG. 2), which promotes mixing, so that the fine water and the atomized medicine can be mixed uniformly.

[0034] In addition, when the control unit 60 judges that the mixing time has elapsed in S260, it switches to a spray state of the spray (mixture) S, which is a mixture of the fine water and the atomized medicine, by opening the first opening / closing damper 16 and the third opening / closing damper 18 and closing the second opening / closing damper 17 (S270). In this spray state, the spray fan 54 is operated to spray the spray (mixture) in the mixing tank 12 from the spray unit 50 (S280), and the power supply to the fine water generating cartridge 30 is turned off to perform moisture absorption control to adsorb moisture to the conductive polymer film 34b (S290), and a predetermined spray time is waited for to elapse (S300). Note that, by operating the spray fan 54, the air sucked into the air passage 22 from the intake port 21a passes through the fine water generating cartridge 30, so that the temperature of the conductive polymer film 34b is reduced to promote the adsorption of moisture.

[0035] Then, when the control unit 60 judges that the spray time has elapsed in S300, it judges whether or not a predetermined treatment time has elapsed (S310), and when it judges that the treatment time has not elapsed, it returns to S200 and performs processing. In this way, the control unit 60 sequentially repeats the supply of the fine water and the atomized medicine, the mixing of the fine water and the atomized medicine, and the spraying of the spray S. The supply time, the mixing time, and the spray time can be appropriately set to a time of about several tens of seconds to several minutes depending on the moisture absorption capacity (moisture release capacity) of the fine water generating cartridge 30, the atomization capacity of the medicine atomization unit 40, the mixed amount (ratio) of the fine water and the atomized medicine, the spray capacity of the spray unit 50, the size of the mixing tank 12, the type and amount of the medicine D, the active ingredient contained, etc. Similarly, the treatment time can be appropriately set to a dozen or so minutes or the like.

[0036] FIG. 6 is an explanatory diagram showing an image of fine water penetrating into the skin. As shown in the figure, the epidermis of the skin is composed of the stratum corneum covered with a sebum film, the granular layer, the spinous layer, and the basal layer (not shown). When the spray S is sprayed onto the skin, the fine water enters the stratum corneum and enters the intercellular lipids between the keratinocytes (see the arrow in FIG. 6). There are gaps of about 20 to 50 nanometers or less on the keratin surface. Since the particle size of the fine water is 50 nanometers or less, about 1 to 2 nanometers, it easily enters the stratum corneum. In addition, since the skin is generally positively charged, if the water particles are negatively charged, they are electrically attracted to the skin surface and have difficulty entering the stratum corneum, and if the water particles are positively charged, they are repelled and have difficulty reaching the skin surface. Since the fine water is uncharged, this does not happen. The fine water that has entered the stratum corneum in this way forms a water route along the intercellular lipids around the keratinocytes. At that time, the moisture content of the intercellular lipids is improved and moisture is also introduced into the natural moisturizing components in the keratinocytes, so that the moisture content of the entire stratum corneum can be brought closer to an appropriate value and moisturizing properties can be improved. In addition, the active ingredient of the spray S diffuses into the skin through the water route formed in the intercellular lipids by the fine water, so that the penetration of the active ingredient can be promoted. In addition to the above-mentioned water route formed by the fine water and the drug diffusing through it, a drug penetration pattern in which the drug is pushed in together with the fine water by the penetration force of the fine water at the same time as the penetration of the fine water is also conceivable. In this way, the fine water brings about an effect of improving moisturizing properties by supplying moisture, and also brings about a synergistic effect of improving the penetration of the active ingredient due to the formation of a water route by the fine water, or the effect of improving the penetration of the active ingredient due to the penetration force of the fine water. The above explains how fine water penetrates the skin, but in the same way, fine water penetrates and remains in the tiny gaps (approximately 50 nm or less) in the cuticle on the surface of the hair, moisturizing the hair. The fine water also forms water routes through which medicinal drugs pass and diffuse. In addition, there is also a possible pattern of medicinal drug penetration in which the medicinal drug is pushed in together with the fine water due to the penetrating power of the fine water at the same time as it penetrates.

[0037] The spray S described above is a mixture of atomized medicine and fine water with a particle size of 50 nanometers or less. Therefore, when the spray S is sprayed onto the skin or hair, the fine water penetrates the skin or hair, forming a water route through which the active ingredient penetrates and providing sufficient moisture. Therefore, the moisturizing effect and penetration effect can be improved.

[0038] In addition, in the cosmetic treatment method, the spray S, which is a mixture of the atomized drug and the fine water, is sprayed toward the skin or hair, so that uneven spraying (adhesion) of the atomized drug and the fine water can be suppressed compared to a method in which the atomized drug and the fine water are sprayed separately, and therefore the penetration and moisturizing properties of the active ingredient can be further appropriately improved. In addition, the spray device 10 can easily adjust the mixed amount (ratio) of the atomized drug and the fine water in the mixing tank 12.

[0039] Here, the spray device 10 of the first embodiment may be configured as follows. FIG. 7 is a schematic diagram showing the configuration of the spray device 10B of the modified example. The spray device 10B is configured similarly to the first embodiment except that the configurations of the fine water supply unit 20B and the medicine atomization unit 40B are different from those of the first embodiment. The fine water supply unit 20B is provided with a discharge element 38 on the communication port 21b side (mixing tank 12 side) of the fine water generating cartridge 30 in the duct 21. In addition, the medicine atomization unit 40B is provided with a discharge element 46 in front of the supply port 45 (atomization unit 44 side). Each discharge element 38, 46 is provided with, for example, a first electrode (discharge electrode) and a second electrode (opposite electrode) arranged opposite the first electrode, and is configured to perform plasma discharge by a drive signal from the control unit 60.

[0040] The spray device 10B can charge the fine water and the atomized medicine by passing the fine water discharged from the fine water generating cartridge 30 and the atomized medicine discharged from the medicine atomizing unit 40B through a plasma region generated by discharge, and supply them to the mixing tank 12. Therefore, it is possible to deodorize the odorous components contained in the outside air passing through the fine water generating cartridge 30 and the medicine atomizing unit 40B, and to inactivate pollen, bacteria, viruses, etc. It is also possible to discharge so that one of the charges of the discharge element 38 and the discharge element 46 becomes positive and the other charge becomes negative. In this way, when the fine water and the atomized medicine are mixed, the particles are attracted to each other to make it easier to mix. In addition, it is also possible to discharge so that the amount of positive charge and the amount of negative charge are equal. In this way, the charge of the entire mixed spray S is neutralized, so that the sprayed spray S is suppressed from being electrically attracted to or repelled by the surface of the skin, and the penetration and the like are prevented from being hindered.

[0041] [Second embodiment] Next, the second embodiment of the present invention will be described. Fig. 8 is a schematic diagram showing the configuration of the spray device 100 of the second embodiment. The spray device 100 includes a mixing tank 112, a fine water supply unit 120, a medicine atomization unit 140, a spray unit 150, and a control unit 160. The fine water supply unit 120 includes an air passage 121, a fine water generating cartridge 130, an electric circuit 135, and a supply fan 136. The configurations other than the air passage 121 are the same as those of the first embodiment, so that the description will be omitted.

[0042] The air passage 121 is composed of a main passage 122, a first communication passage 124, and a second communication passage 127, and is provided with a first switching section 125 and a second switching section 128. The main passage 122 is a cylindrical passage with both ends open. In the main passage 122, a supply fan 136 and a fine water generating cartridge 130 are provided in this order from a first opening 122a on one side to a second opening 122b on the other side. The first communication passage 124 and the second communication passage 127 communicate the main passage 122 and the mixing tank 112. The first communication passage 124 is connected to the main passage 122 on the first opening 122a side of the supply fan 136 and extends into the mixing tank 112. The second communication passage 127 is connected to the main passage 122 on the second opening 122b side of the fine water generating cartridge 130 and extends into the mixing tank 112.

[0043] The first switching unit 125 has a switching plate 126 that is operated by driving a motor (not shown), and the second switching unit 128 has a switching plate 129 that is operated by driving a motor (not shown). As shown by solid lines in FIG. 8, when the switching plate 126 is in the normal position (initial position), the first switching unit 125 closes (blocks) the first communication passage 124 and opens the first opening 122a side to allow air to flow through the first opening 122a. When the switching plate 129 is in the normal position, the second switching unit 128 closes (blocks) the second communication passage 127 and opens the second opening 122b side to allow air to flow through the second opening 122b. This state is called a sealed state (blocked state) because the mixing chamber 112 is blocked from the main passage 122 and sealed.

[0044] On the other hand, as shown by the dotted line in Fig. 8, when the switching plate 126 is operated to an operating position rotated 90 degrees by the driving of the motor, the first switching unit 125 opens the first communication passage 124 and closes the first opening 122a side so as to prevent air from flowing through the first opening 122a. When the switching plate 129 is operated to an operating position rotated 90 degrees by the driving of the motor, the second switching unit 128 opens the second communication passage 127 and closes the second opening 122b side so as to prevent air from flowing through the second opening 122b. In this state, the mixing chamber 112 and the main passage 122 communicate with each other through the first communication passage 124 and the second communication passage 127, and air can circulate between the mixing chamber 112 and the main passage 122, so this state is called a circulation state (communication state).

[0045] In the spray device 100 thus configured, moisture absorption control and moisture release control (supply into the mixing tank 12) of the fine water are performed as follows. In moisture absorption control, the control unit 160 sets the above-mentioned sealed state, turns off the power supply to the fine water generating cartridge 130, and drives the supply fan 136 to adsorb moisture into the conductive polymer film 34b. This reduces the temperature of the conductive polymer film 34b, promoting the adsorption of moisture. The rotation direction of the supply fan 136 may be, for example, the direction in which air flows from the first opening 122a to the second opening 122b (see the solid arrow in FIG. 8).

[0046] In addition, in the moisture release control, the control unit 160 sets the above-mentioned circulation state, turns on the power supply to the fine water generating cartridge 130, and drives the supply fan 136 to supply the fine water discharged from the conductive polymer film 34b into the mixing tank 112. The rotation direction of the supply fan 136 may be, for example, the same direction as that of the moisture absorption control, and the air blown from the supply fan 136 passes through the fine water generating cartridge 130, flows from the second communication passage 127 into the mixing tank 112, and circulates to return to the main passage 122 through the first communication passage 124 (see the dotted arrow in FIG. 8). Therefore, the fine water is supplied from the fine water generating cartridge 130 into the mixing tank 112 using the circulating air without newly introducing air, so that the number of particles of the fine water in the mixing tank 112 increases, and a high concentration environment of the fine water can be created. As a result, the spray in which the fine water is sufficiently mixed can be sprayed, and the penetration and moisturizing properties of the active ingredient can be further improved.

[0047] In the first and second embodiments, a humidity sensor may be provided in the mixing tank 12, 112, and the humidity detected by the humidity sensor may be used as a substitute characteristic for the number of fine water particles to adjust the supply time, mixing time, and spray time, or change the airflow rate of each fan.

[0048] [Third embodiment] Next, a third embodiment of the present invention will be described. Fig. 9 is a schematic diagram showing the configuration of the spray device 200 of the third embodiment. The spray device 200 is disposed in the discharge head 4B, and includes a fine water supply unit 220, a medicine atomization unit 240, and a control unit (not shown). This spray device 200 does not include a mixing tank 12 or a spray unit 50, and is configured to spray the fine water and the atomized medicine separately without mixing them.

[0049] The fine water supply unit 220, like the fine water supply unit 20, includes a fine water generating cartridge 230 and a supply fan 236 in the duct 221, and discharges the fine water from the fine water discharge port 221a toward the treatment target area (marked with an x ​​in the figure). 2 42 and the atomization section2 44. The medicine nebulization unit 240 also includes a duct 241 to which the medicine nebulized by the nebulization unit 44 is supplied, and a fan 246 for ejecting the atomized medicine (air) in the duct 241 from the medicine outlet 241a, and ejects the atomized medicine from the medicine outlet 241a toward the treatment site.

[0050] In the spray device 200 of the third embodiment, the fine water and the atomized medicine can be discharged separately, so that the fine water and the atomized medicine can be sprayed separately onto the skin or hair. Therefore, the fine water can be sprayed first to form a water route and then the atomized medicine can be sprayed, or conversely, the atomized medicine can be sprayed first and then the fine water can be sprayed. This may be switched depending on the difference in the medicine components and the purpose of the treatment of the skin or hair. In addition, the atomized medicine can be sprayed during the moisture absorption control of the fine water, so that the beauty treatment can be performed efficiently.

[0051] In the fine water supply unit 20, 120, 220 of each embodiment, in addition to the fine water generating cartridge 30, 130, 230 and the supply fan 36, 136, 236, a temperature control cartridge (heat exchanger) may be provided. The temperature control cartridge is formed of a metal material, for example, in a corrugated plate shape, honeycomb shape, or spiral shape, so as to have a large heat capacity and high heat exchange efficiency. Then, air containing fine water discharged from the fine water generating cartridge 30, 130, 230 during moisture release control passes through the temperature control cartridge and is supplied into the mixing tank 12, 112, or is discharged from the fine water discharge port 221a. In this way, the air whose temperature has been raised by the fine water generating cartridge 30, 130, 230 is cooled to near room temperature when passing through the temperature control cartridge, so that fine water can be appropriately supplied or discharged without increasing the temperature.

In the embodiment, S270 and S280 of the spraying process correspond to the spraying step. S240 and S250 correspond to the mixing step.
