Abstract

This cosmetic treatment method comprises a spraying step for spraying, toward skin or hair, an atomized agent obtained by atomizing a medical agent containing a predetermined active ingredient, and uncharged fine water having a particle size of less than or equal to 50 nanometers. The sprayed fine water therefore enters the skin or hair to contribute to sustained moisture retention and forms a route for the active ingredient to permeate to promote such permeation. Thus, the permeability of the active ingredient can be increased more appropriately.

Skin or hair spray, beauty treatment method and spray device

The present disclosure relates to a skin or hair spray, a cosmetic treatment method, and a spray device.

Conventionally, there has been proposed a device that is equipped with a liquid agent spraying mechanism that atomizes a liquid agent by electrostatic atomization and a mist generation mechanism that generates a mist, and that sprays the liquid agent with a fine particle size by electrostatic atomization together with the mist. there is For example, in the device disclosed in 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 provided separately, and the liquid agent spraying mechanism and the mist generating mechanism are controlled so as to spray simultaneously.

JP 2010-172659 A

However, when liquid agents and water particles are charged by electrostatic atomization, etc., as in the device described above, they may be electrically attracted to the surface of the stratum corneum of the skin, making it difficult to permeate the stratum corneum. Further, in the case where the liquid agent spray port and the mist ejection port are separately provided, it may be difficult to uniformly mix the sprayed liquid agent and the mist.

The main purpose of the present disclosure is to more appropriately improve the permeability of active ingredients when the spray is sprayed onto the skin or hair.

This disclosure has taken the following means to achieve the above-mentioned main objectives.

The propellant of the present disclosure is
A skin or hair spray comprising:
The gist of the present invention is that an atomized medicine containing a prescribed active ingredient is mixed with fine water having a particle size of 50 nanometers or less and uncharged.

The spray of the present disclosure is a mixture of an atomized drug and fine water that is uncharged and has a particle size of 50 nanometers or less. When this spray is sprayed onto the skin or hair, fine water penetrates into the skin or hair, contributing to the maintenance of moisturizing and forming a route through which the active ingredients permeate, promoting permeation. can be better improved. In addition, since fine water is particles having no charge, that is, it is non-charged, it can permeate into the stratum corneum of the skin without being electrically attracted to the surface of the stratum corneum of the skin. Furthermore, it is said that the gap between the stratum corneum of the skin is about 20 to 50 nanometers or less, and since the fine water has a particle size of 50 nanometers or less, it can easily enter the gap between the stratum corneum and has a penetration effect. It is a high reason.

The cosmetic treatment method of the present disclosure involves spraying an atomized drug obtained by atomizing a drug containing a predetermined active ingredient and fine water, which is uncharged and has a particle size of 50 nanometers or less, toward the skin or hair. The gist is to include steps. Therefore, it is possible to more appropriately improve the permeability of the active ingredient when the spray is sprayed onto the skin or hair.

The cosmetic treatment method of the present disclosure includes a mixing step of mixing the atomized drug and the fine water, and in the spraying step, a spray agent in which the atomized drug and the fine water are mixed in the mixing step. , may be sprayed onto the skin or hair. In this way, the atomized drug and the fine water can be sprayed in a sufficiently mixed state as compared with spraying separately, so that uneven spraying can be prevented and the penetration of the active ingredient can be more appropriately achieved. can be improved. Also, the mixing amount (proportion) of the atomized medicine and the fine water can be easily adjusted.

The spray device of the present disclosure includes:
an atomization unit that generates an atomized drug by atomizing a drug containing a predetermined active ingredient;
A moisture absorption state in which moisture in the air is absorbed by the conductive polymer film due to a decrease in temperature, and a moisture desorption condition in which moisture absorbed by the conductive polymer film is released as fine water having a particle size of 50 nanometers or less due to a temperature increase. A fine water generating portion that changes to
a spraying unit that sprays the atomized drug and the fine water toward the skin or hair;
The gist is to provide

In the spraying device of the present disclosure, the atomized drug generated in the atomizing part and the fine water generated by changing the fine water generating part between the moisture absorbing state and the moisture releasing state are discharged from the spraying part toward the skin or hair. to spray. Therefore, it is possible to more appropriately improve the permeability of the active ingredient when the spray is sprayed onto the skin or hair.

In the spraying device of the present disclosure, a mixing unit communicating with the atomizing unit, the fine water generating unit, and the spraying unit and mixing the atomized chemical and the fine water is provided, and the spraying unit includes the mixing unit. A propellant in which the atomized drug and the fine water are mixed may be sprayed at the part. This makes it easier to adjust the mixing ratio of the atomized medicine and the fine water compared to spraying separately, so that the permeability of the active ingredient can be improved more appropriately.

Further, in the spraying device, a mixing section that communicates with the atomizing section, the fine water generating section, and the spraying section and mixes the atomized chemical and the fine water; A hygroscopic state in which air outside the mixing section is supplied to the heated conductive polymer film to absorb moisture in the air to the conductive polymer film, and a moisture release state in which the air is circulated and the moisture adsorbed on the conductive polymer film is released into the mixing section as fine water having a particle size of 50 nanometers or less, and the fine water in the mixing section is released. and a control unit that controls to increase the concentration, and the spray unit may spray the spray in which the atomized medicine and the fine water are mixed in the mixing unit. In this way, the fine water and the atomized medicine can be mixed in a state where the concentration of the fine water in the mixing section is increased. Therefore, since the spray agent in which fine water is sufficiently mixed can be sprayed, it is possible to further improve the permeability of the active ingredient while enhancing the moisturizing effect.

In the spray device of the present disclosure, a sealed state in which communication between the fine water generating section and the mixing section is cut off and air outside the mixing section is supplied to the fine water generating section; A switching unit for selecting either one of a circulation state in which the mixing units are communicated and the air of the mixing unit is supplied to the fine water generating unit, and the concentration of the fine water in the mixing unit is increased. The fine water generating portion may be in the moisture absorbing state when the switching portion is closed, and may be in the moisture releasing state when the switching portion is in the circulating state. By doing so, the fine water can be sufficiently mixed with the propellant by making the inside of the mixing section into a high-concentration environment of the fine water.

In the cosmetic treatment method of the present disclosure, the step of adsorbing moisture to a conductive polymer film having nanochannels, and increasing the temperature of the conductive polymer film to release the moisture adsorbed to the conductive polymer film. and, in the mixing step, the fine water may be mixed with the atomized medicine. By doing so, fine water having a smaller particle size can be mixed with the atomized medicine, so that the permeability of the active ingredient can be further improved.

FIG. 3 is a configuration diagram showing an outline of the configuration of the fine water generation cartridge 30. As shown in FIG.

As shown in FIG. 1, the beauty treatment device 1 includes a device main body 2 that houses a spray device 10, a discharge head 4 that discharges the spray generated by the spray device 10, and a discharge head 4 attached to the tip. A movable arm 5 and a support portion 6 that supports the proximal end of the movable arm 5 to the apparatus main body 2 are provided. The device body 2 is movably supported by casters 3 attached to the bottom. The movable arm 5 has a supply path for the spray to the discharge head 4 formed therein, the discharge head 4 is rotatably attached to the distal end, and the base end is rotatably supported by the support portion 6 . . Therefore, the ejection head 4 can be moved and turned in the vertical, horizontal, and longitudinal directions with respect to the apparatus main body 2, and can be adjusted to a position suitable for the treatment target. This beauty treatment device 1 is installed, for example, in an esthetic salon or beauty salon, and may be installed in an individual's home.

The spray device 10 includes a mixing tank 12, a fine water supply unit 20, a drug atomization unit 40, and a spray unit 50, as shown in FIG.

The mixing tank 12 has a rectangular parallelepiped or cylindrical shape, is equipped with a mixing fan 14 inside, and has a fine water supply unit 20, a drug atomization unit 40, and a spray unit 50 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 communication and disconnection between the fine water supply unit 20 and the inside of the tank by opening and closing operations, and a first opening/closing damper 16 that switches communication and disconnection between the drug atomization unit 40 and the inside of the tank by opening and closing operations. A second opening/closing damper 17 and a third opening/closing damper 18 for switching communication and disconnection between the spray unit 50 and the inside of the tank by opening/closing operation are provided. Each of the first to third opening/closing dampers 16 to 18 performs an opening/closing operation by operating an opening/closing plate by driving a motor (not shown).

The fine water supply unit 20 includes a duct 21 in which an air passage 22 is formed, a fine water generation cartridge 30, an energization circuit 35, and a supply fan 36.

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/closing damper 16. of air passages 22 are formed. 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.

As shown in FIG. 3A, the fine water generating cartridge 30 includes a cylindrical case 32 with an outer diameter that can be arranged in the air passage 22 and a fine water generating element 34 provided inside the case 32 . As shown in FIG. 3B, the fine water generating element 34 includes a substrate 34a and a conductive polymer film 34b formed on the surface of the substrate 34a.

The base material 34a is made of a conductive material such as a metal material such as a stainless metal or a copper metal, a carbon material, or a conductive ceramic material. In this embodiment, a metal foil made of stainless steel to which aluminum is added is used. The fine water generating element 34 is formed in a corrugated plate shape, a honeycomb shape, a spiral shape, or the like so that air can flow through and the surface area of the base material 34a (conductive polymer film 34b) is as large as possible. there is An energization circuit 35 including a power supply and a switch is connected to the base material 34a. When the switch is turned on by the controller 60, the energization circuit 35 enters an energized state in which the substrate 34a is energized. Become.

The conductive polymer film 34b is formed of a conductive polymer compound such as a thiophene-based conductive polymer. In this embodiment, it is made 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. Also, 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 are present in the nanochannels, the water content on the surface of the conductive polymer film 34b is reduced to Due to the difference, it moves inside along the sulfonic acid groups in the nanochannel. As a result, the conductive polymer film 34b absorbs moisture. In addition, when moisture is adsorbed inside the nanochannel and the amount of moisture on the surface is small and the amount of moisture on the inside is large, 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, water is released as fine water from the conductive polymer film 34b. In addition, when the temperature of the conductive polymer film 34b rises, the release of moisture (microscopic water) is accelerated more quickly than when it moves only by the concentration difference, and the temperature of the conductive polymer film 34b decreases. In such a state, water is adsorbed more quickly than when it is moved only by the concentration difference. In this manner, the fine water generating cartridge 30 (fine water generating element 34) changes to a moisture absorption state in which moisture in the air is adsorbed by the conductive polymer film 34b due to a decrease in temperature. It changes to a dehumidifying state in which it is released from the polymer film 34b. The thickness of the conductive polymer film 34b can be appropriately determined according to the required adsorption amount (release amount) of fine water. For example, when the conductive polymer film 34b is formed to have a thickness of 1 to 30 micrometers, it takes several seconds to several tens of seconds to absorb sufficient moisture to release fine water. is possible.

The fine water generating cartridge 30 is a non-charged fine water particle having a particle size of 50 nanometers or less, for example, a particle size of about 1 to 2 nanometers, from the conductive polymer film 34 b of the fine water generating element 34 . Release water. The reason for such a particle size is that the size of the nanochannel is 2 nanometers or less. This is thought to be due to a phenomenon in which moisture jumps out of nanochannels. Moreover, even if the water particles agglomerate after being ejected, the particle size is distributed within a range of 50 nanometers or less. Detailed description of fine water generation of such a fine water generation cartridge 30 (conductive polymer film 34b) is described in WO2020/054100 and Japanese Patent Application Laid-Open No. 2019-018195 of the applicant of the present application. The above detailed description is omitted.

The supply fan 36 blows air from the intake port 21a outside the mixing tank 12 toward the inside of the mixing tank 12 (communication port 21b) by being rotationally driven in a predetermined rotational direction. Therefore, the 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 rotationally driven by a motor (not shown) and controlled by a control unit 60 by PWM (Pulse Width Modulation) control, voltage control, or the like. The supply fan 36 may be a propeller fan, a sirocco fan, or the like.

The drug atomization unit 40 includes a drug tank 42 that stores the drug D, and an atomization part 44 that atomizes the drug D stored in the drug tank 42 and supplies it into the mixing tank 12 from the supply port 45 . The atomization unit 44 is configured to atomize the drug D by, for example, an ultrasonic atomization method that atomizes the drug by vibration of a piezoelectric element. In addition, the atomization part 44 may be configured to atomize the medicine D by other methods such as an air spray method, an electrostatic atomization method, and a centrifugal atomization method. Also, the supply port 45 is opened and closed by the second opening/closing damper 17 .

The drug D stored in the drug tank 42 contains a mixture of cosmetic ingredients, medicinal ingredients, and the like as predetermined active ingredients. Examples of the drug D and active ingredients include moisturizing ingredients, crude drug extracts, enzymes such as tyrosinase, superoxide dismutase, and lipase, vitamins and derivatives thereof such as retinol, ascorbic acid, tocopherol, pyridoxal, and riboflavin, β-carotene, Organic pigments such as chlorophyll, glycerin, sorbitol, urea, lactic acid, propylene glycol, polyethylene glycol and copolymers, moisture ingredients such as glucose derivatives, paraffin, stearyl alcohol, cetyl alcohol, squalane, silicone oil, stearyl, etc. emollient ingredients, treatment ingredients, dandruff-suppressing ingredients, hair nourishing ingredients, and hair-restoring ingredients, but are not limited to these.

The spray unit 50 includes a duct 51 with an air passage 52 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/closing damper 18. Further, the duct 51 is formed in a tapered shape so that the cross-sectional area of the air passage 52 on the spray port 51a side of the spray fan 54 becomes smaller toward the spray port 51a side. The spray unit 50 takes in the spray in the mixing tank 12 by operating the spray fan 54 and sprays it from the spray port 51a. The spray sprayed from the spray port 51 a reaches the discharge head 4 through the supply channel in the movable arm 5 .

The control unit 60 is configured as a microprocessor centered around a CPU, and is equipped with ROM, RAM, and input/output ports in addition to the CPU. The control unit 60 receives an operation signal from a start switch 62 for starting the operation of the spray device 10, and an operation from an air volume adjustment switch 64 for adjusting the air volume of each

fan

14, 36, 54 individually or collectively. A signal or the like is input through the input port. Further, from the control unit 60, drive signals to the motors that rotationally drive the

fans

14, 36, 54, drive signals to the first to third opening/closing dampers 16 to 18, drive signals to the switches of the energization circuit 35, etc. is output through the output port.

Next, a description will be given of a cosmetic treatment method for spraying a spray agent onto the skin or hair using the cosmetic treatment device 1 (spraying device 10) configured in this way. FIG. 4 is a process chart showing an example of a cosmetic treatment method. A practitioner (clerk) of a beauty salon or the like replenishes (contains) 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 ejection head 4 so that the ejection head 4 can eject the spray toward the target site of the subject (step S110), and operates the start switch 62. Then, the spraying process is performed by the spraying device 10 (step S110). Through this spraying process, the spray produced by the spraying device 10 is discharged from the discharge head 4 and sprayed onto the skin and hair of the subject.

FIG. 5 is a process diagram showing an example of the spraying process. In the spraying process, the control unit 60 of the spraying device 10 opens the first opening/closing damper 16 and the second opening/closing damper 17 and closes the third opening/closing damper 18, thereby (S200). In this supply state, fine water is supplied into the mixing tank 12 by means of moisture release control in which the fine water generating cartridge 30 is energized and the supply fan 36 is driven in a predetermined rotational direction (S210). to supply the atomized medicine into the mixing tank 12 (S220), and wait for a predetermined supply time to elapse (S230). In S210, the supply fan 36 is rotationally driven in a predetermined rotational direction, so that the air sucked from the intake port 21a is discharged into the mixing tank 12 from the communication port 21b (see the dotted line arrow in FIG. 1). In addition, since the fine water generating cartridge 30 is turned on, the temperature of the conductive polymer film 34b rises, promoting the release of fine water. In addition, when the spraying process is started in a state where the conductive polymer film 34b does not absorb moisture, before S210, the supply fan 36 is driven and the supply fan 36 is turned off before S210. Moisture absorption control may be performed to cause the flexible polymer film 34b to absorb moisture.

When the control unit 60 determines in S230 that the supply time has elapsed, the control unit 60 closes the first opening/closing damper 16, the second opening/closing damper 17, and the third opening/closing damper 18, thereby removing the fine water and the atomized medicine. (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 wait for a predetermined mixing time to elapse (S260). The operation of the mixing fan 14 creates an air flow in the mixing tank 12 (see the dotted line arrow in FIG. 2) to promote mixing, so that the fine water and the atomized medicine can be uniformly mixed.

Further, when it is determined in S260 that the mixing time has elapsed, the control unit 60 opens the first opening/closing damper 16 and the third opening/closing damper 18, and closes the second opening/closing damper 17, thereby finely The state is switched to the spraying state of the spray (admixture) S in which water and the atomized drug are mixed (S270). In this spraying state, the spraying agent (mixture) in the mixing tank 12 is sprayed from the spraying unit 50 by operating the spraying fan 54 (S280). While performing moisture absorption control for adsorbing moisture to the molecular film 34b (S290), the process waits for a predetermined spray time to elapse (S300). By the operation of 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 lowered to promote adsorption of moisture. can be done.

If the control unit 60 determines in S300 that the spraying time has elapsed, it determines whether or not the predetermined treatment time has elapsed (S310), and if it determines that the treatment time has not elapsed, the process returns to S200. I do. In this manner, the control unit 60 repeats the supply of fine water and the atomized chemical, the mixing of the fine water and the atomized chemical, and the spraying of the propellant S in this order. The supply time, mixing time, and spraying time depend on the moisture absorbing ability (moisture releasing ability) of the fine water generating cartridge 30, the atomizing ability of the drug atomization unit 40, the mixing amount (ratio) of fine water and the atomized drug, and the spray unit 50. , the size of the mixing tank 12, the type and amount of the drug D, the contained active ingredient, etc., the time can be appropriately set from several tens of seconds to several minutes. Similarly, the treatment time can also be appropriately set to several ten minutes or several tens of minutes.

Here, FIG. 6 is an explanatory diagram showing an image of how fine water permeates the skin. As illustrated, the epidermis of the skin consists of a stratum corneum covered with a sebaceous membrane, a granular layer, a stratum spinosum, a basal layer (not shown), and the like. When spray agent S is sprayed onto the skin, fine water enters the stratum corneum and intercellular lipids between corneocytes (see arrows in FIG. 6). The stratum corneum surface has gaps on the order of 20 to 50 nanometers or less. Since fine water has a particle size of 50 nanometers or less and is 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 will be electrically attracted to the skin surface and will not easily enter the stratum corneum, and the water particles will be positively charged. If it is, it will repel and it will be difficult to reach the skin surface. Since fine water is non-charged, there is no such problem. The microscopic water thus entering the stratum corneum forms a water route along the intercellular lipids surrounding the corneocytes. At this time, the water content of the intercellular lipids increases and the natural moisturizing ingredients in the corneocytes also contain water, so that the water content of the entire stratum corneum can be brought close to an appropriate value to improve the moisturizing properties. In addition, since the active ingredient of the spray S passes through the route of the water formed in the intercellular lipid by fine water and diffuses into the skin, the permeation of the active ingredient can be promoted. In addition to the above-mentioned fine water forming a water route through which the drug diffuses, at the same time that the fine water permeates, the drug is pushed in together with the fine water due to the osmotic power of the fine water. Several patterns of drug permeation are possible. In this way, the fine water has the effect of improving the moisturizing property by supplying water, and the effect of improving the permeability of the active ingredient due to the formation of the water route by the fine water, or the penetration of the active ingredient due to the penetration power of the fine water. It synergistically brings about the permeability improvement effect. Although the above describes how fine water penetrates the skin, the fine water penetrates and stays in the fine gaps (about 50 nm or less) of the cuticle on the surface of the hair in the same way, thereby moisturizing the hair. In addition to forming a water route with fine water and diffusing the drug through it, we also considered a drug penetration pattern in which the drug is pushed in with the fine water due to the osmotic power of fine water at the same time as the penetration of fine water. be done.

The spray agent S described above is a mixture of an atomized agent and fine water with a particle size of 50 nanometers or less. Therefore, when the spray agent S is sprayed onto the skin or hair, fine water permeates the skin or hair, thereby forming a water route through which the active ingredient permeates and sufficiently moisturizing the skin or hair. Therefore, the moisturizing effect and the permeation effect can be enhanced.

In addition, in the beauty treatment method, the spray agent S, which is a mixture of the atomized drug and fine water, is sprayed toward the skin or hair. Since uneven spraying (adhesion) of the atomized medicine and fine water can be suppressed, the permeability and moisturizing properties of the active ingredient can be further appropriately improved. Further, the spray device 10 can easily adjust the mixing amount (proportion) of the atomized medicine and the fine water in the mixing tank 12 .

Here, the spray device 10 of the first embodiment may be configured as follows. FIG. 7 is a configuration diagram showing an outline of the configuration of a spray device 10B of a modified example. The spray device 10B has the same configuration as that of the first embodiment except that the configuration of the fine water supply unit 20B and the drug atomization unit 40B is different. The fine water supply unit 20B includes a discharge element 38 in the duct 21 on the communication port 21b side (mixing tank 12 side) of the fine water generation cartridge 30 . In addition, the drug atomization unit 40B includes a discharge element 46 in front of the supply port 45 (on the side of the atomization section 44). Each of the

discharge elements

38 and 46 includes, for example, a first electrode (discharge electrode) and a second electrode (counter electrode) arranged to face the first electrode, and plasma discharge is performed by a drive signal from the control unit 60. is configured to do

The spray device 10B charges the fine water and the atomized drug by causing the fine water discharged from the fine water generation cartridge 30 and the atomized drug discharged from the drug atomization unit 40B to pass through the plasma region generated by the discharge. , and these can be supplied to the mixing tank 12 . Therefore, it is possible to deodorize odorous components contained in the outside air passing through the fine water generation cartridge 30 and the medicine atomization unit 40B, and to inactivate pollen, germs, viruses, and the like. It should be noted that discharge may be performed such that one of the discharge by the discharge element 38 and the discharge by the discharge element 46 is positive and the other is negative. In this way, when the fine water and the atomized medicine are mixed, the particles can be attracted to each other and mixed easily. Alternatively, the discharge may be performed so that the amount of positive charge and the amount of negative charge are equal. In this way, the charge of the mixed propellant S as a whole is neutralized, so that the sprayed propellant S is suppressed from being electrically attracted to or repelled from the surface of the skin, and penetration and the like are improved. can be prevented from being hindered.

The spray device 100 includes a mixing tank 112 , a fine water supply unit 120 , a drug atomization unit 140 , a spray unit 150 and a controller 160 . The fine water supply unit 120 includes an air passage 121, a fine water generation cartridge 130, an energizing circuit 135, and a supply fan 136. Components other than the air passage 121 are the same as those of the first embodiment. Therefore, the explanation is omitted.

The air passage 121 is composed of a main passage 122, a first communication passage 124 and a second communication passage 127, and a first switching portion 125 and a second switching portion 128 are provided. The main passage 122 is a tubular passage open at both ends. In the main passage 122, a supply fan 136 and a fine water generation cartridge 130 are provided in this order from the first opening 122a on one side toward the 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 122 a 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 122 b side of the fine water generation cartridge 130 and extends into the mixing tank 112 .

The first switching portion 125 has a switching plate 126 that is driven by a motor (not shown), and the second switching portion 128 has a switching plate 129 that is driven by a motor (not shown). 8, when the switching plate 126 is in the normal position (initial position), the first switching portion 125 closes (shuts off) the first communication path 124 and allows air to flow through the first opening 122a. The first opening 122a side is opened so as to allow the flow of the In addition, when the switching plate 129 is in the normal position, the second switching portion 128 closes (blocks) the second communication path 127 and opens the second opening 122b so as to allow air to flow through the second opening 122b. open the side. This state is called a sealed state (blocked state) because the mixing tank 112 is shut off from the main passage 122 and sealed.

On the other hand, as indicated by the dotted line in FIG. 8, when the switching plate 126 is driven by the motor to the operating position where the switching plate 126 is rotated by 90 degrees, the first switching portion 125 opens the first communication path 124 and opens the first opening 122a. The side of the first opening 122a is closed so as to prevent air from flowing through. Further, when the switching plate 129 is rotated by 90 degrees due to the driving of the motor, the second switching portion 128 opens the second communication path 127 and prevents air from flowing through the second opening 122b. , the second opening 122b side is closed. In this state, the mixing tank 112 and the main passage 122 communicate with each other through the first communication passage 124 and the second communication passage 127, and the air can circulate through the mixing tank 112 and the main passage 122. It is called a state (communication state).

In the spray device 100 configured in this way, moisture absorption control and moisture release control (supply into the mixing tank 12) of fine water are performed as follows. In the moisture absorption control, the controller 160 sets the above-described closed state, turns off the power supply to the fine water generation cartridge 130, and drives the supply fan 136 to cause the conductive polymer film 34b to adsorb moisture. As a result, the temperature of the conductive polymer film 34b is lowered, promoting the adsorption of moisture. The direction of rotation 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 line arrow in FIG. 8).

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

In the first and second embodiments, a humidity sensor is provided in the

mixing tank

12, 112, and the humidity detected by the humidity sensor is used as a substitute characteristic for the number of fine water particles. The time may be adjusted or the air volume of each fan may be changed.

[Third embodiment]

The spray device 200 is arranged inside the ejection head 4B, and includes a fine water supply unit 220, a drug atomization unit 240, and a controller (not shown). The spray device 200 does not include the mixing tank 12 or the spray unit 50, and is configured to spray fine water and the atomized medicine separately without mixing them.

Similar to the fine water supply unit 20, the fine water supply unit 220 includes a fine water generation cartridge 230 and a supply fan 236 in the duct 221, and fine water is supplied from the fine water outlet 221a to the treatment target area (marked with x in the figure). ). The drug atomization unit 240 includes a drug tank 42 and an atomization section 44, similar to the drug atomization unit 40. As shown in FIG. The drug atomization unit 240 also includes a duct 241 to which the drug atomized by the atomization section 44 is supplied, and a fan 246 for ejecting the atomized drug (air) in the duct 241 from a drug discharge port 241a. , the atomized medicine is discharged from the medicine discharge port 241a toward the site to be treated.

In the spraying device 200 of the third embodiment, the fine water and the atomized medicine can be separately discharged, so that the fine water and the atomized medicine can be separately sprayed onto the skin and hair. Therefore, fine water can be sprayed first to form a water route, and then the atomizing chemical can be sprayed, or conversely, fine water can be sprayed after the atomizing chemical is sprayed. This may be switched depending on the difference in drug components and the purpose of skin and hair treatment. In addition, since the atomization medicine can be sprayed while controlling the moisture absorption of the fine water, the beauty treatment can be performed efficiently.
