The conventional cosmetological device has the configuration shown in each of the patent documents, and such a device has a mechanism of heating or cooling an electrode for energization as well as energization for causing iontophoresis to the skin. When using, the electrode protruding from the main body of the device is usually applied to the skin of a beauty object such as the face, and then the skin is energized, the electrode is heated to warm the skin, or the electrode is cooled. The user will perform the operation to cool the skin.

In such a conventional device, when the electrode is brought into contact with the skin and the skin is energized for iontophoresis, and at the same time, the electrode is heated to warm the skin, the ionic component and other components can be permeated into the skin. It is known that such execution of energization and heat application to the skin is often adopted as one of the main operating modes of the device.

However, if the skin is energized and heated at a time when the temperature is high and it is difficult for heat to be dissipated from the skin, such as in summer, or when the skin is sufficiently warm, such as after taking a bath, the effect of iontophoresis will be effective. Although it increases, there is a problem that heat is trapped in the skin and the skin becomes lit, which may lead to discomfort to the user.

On the other hand, a device having a function of warming the skin and a function of cooling the skin can cool the heat of the previously warmed skin and obtain a feeling of comfort by applying a cooled electrode to the skin. However, after the execution of the energization and heat application modes related to iontophoresis is stopped, it is necessary to select and execute the skin cooling mode again by the user's operation, and in the case of a device where the skin warming part and the skin cooling part are different. There is a problem that troublesome operations are required, such as the user having to change the device and touch the skin to the part where the skin is cooled.

The present invention has been made to solve the above-mentioned problems, in which temperature changes of hot and cold are alternately generated in one heat transfer part, and the temperature of the skin is stimulated at the same time as the operation related to the single or other stimulation application. The purpose is to provide a beauty device that can be continuously added with cold stimulation, does not require troublesome operations, can be used comfortably in any situation, and maximizes the effects related to beauty. ..

The beauty device disclosed in the present invention includes a main body portion held by the user and a stimulus applying portion that is integrally disposed with the main body portion and can apply a predetermined stimulus related to beauty to the user's skin. In a beauty device that gives the user's skin the predetermined stimulus by bringing the stimulating portion close to or in contact with the user's skin, the stimulating portion is formed of a material having thermal conductivity and is formed with the user's ambient temperature. Is arranged in the vicinity of a heat transfer portion as at least one of the stimulus applying portions, which changes to different temperatures and imparts a stimulus based on the temperature to the user's skin, and heat transfer by energization. It is provided with a heat source unit that heats and cools the unit and a control unit that can control the energization of the heat source unit to adjust the heating / cooling state of the heat transfer unit by the heat source unit. The heat source unit is controlled so that the contacted heat transfer unit is heated to a first predetermined temperature higher than the ambient environment temperature and cooled to a second predetermined temperature lower than the ambient environment temperature alternately. It is something to do.

As described above, according to the disclosure of the present invention, a heat transfer unit that changes the temperature and gives a stimulus based on the temperature is arranged as a stimulus applying unit that gives a stimulus related to beauty to the skin, and is energized by the control unit. A heat source unit that heats and cools the heat transfer unit is provided based on the control, and the control unit controls the temperature of the heat source unit while the heat transfer unit is close to or in contact with the user's skin, and the heat source unit controls. The heat transfer part is heated and the heat transfer part is cooled alternately, and the heat transfer part alternately gives warm and cold stimuli to the skin to heat the heat transfer part to the skin. The cold stimulus is subsequently applied after the stimulus, and the discomfort that may occur due to the preceding warm stimulus applied to the skin can be alleviated and suppressed by the subsequent cold stimulus application. The effect of the stimulus associated with the temperature change and the synergistic effect with the stimulus from other stimulus-imparting portions given at the same time can be appropriately and appropriately given to the skin. In addition, when alternately applying warm and cold stimuli to the skin in the heat transfer part, for example, switching operation by the user of each operation mode for executing warm stimulus and cold stimulus, and for warm stimulus and cold stimulus are applied. It is not necessary to operate the device to replace each stimulus-giving portion and bring it into contact with the skin, and the stimulus-giving state can be easily obtained, so that the user does not feel the troublesome operation.

In addition, by repeating the alternating application of warm and cold stimuli to the skin, the effect of promoting blood circulation and metabolism on the skin by the warm stimulus, and the effect of tightening the skin by the cold stimulus, etc., are applied to the skin for each stimulus. In addition to the effect, the muscles directly under the skin are given the effect of promoting blood circulation and recovering from fatigue based on the alternating heating and cooling, and the tension relaxing effect similar to that when massaging the muscles can be obtained, especially on the skin on the face. With the synergistic effect on the skin, a lift-up effect similar to face massage can be expected.

Further, in the beauty device disclosed in the present invention, if necessary, the control unit has the same length as the temperature period in which the temperature is higher than the ambient temperature in the heat transfer unit and the cold period in which the temperature is lower than the ambient temperature. Therefore, the control of the heat source unit is executed.

As described above, according to the disclosure of the present invention, the control unit controls the heating and cooling states of the heat transfer unit by the heat source unit, so that the temperature of the heat transfer unit is higher than the ambient temperature and the temperature of the heat transfer unit is the ambient temperature. By ensuring that the cold period below the ambient temperature has the same length in time, the warm and cold stimuli are balanced, and one of the more applied stimuli has less effect on the skin. It is possible to prevent the effect of the stimulus on the skin from becoming inconspicuous, and the user can evenly feel the amount of warm stimulus and the amount of cold stimulus given to the skin from the heat transfer part. An appropriate stimulus-giving state can be obtained without causing a sense of discomfort or an excess or deficiency of stimulus due to the difference in the amount of stimulus.

Further, in the beauty device disclosed in the present invention, if necessary, the degree of temperature rise per unit time of the heat transfer unit in the state where the control unit warms the heat transfer unit cools the heat transfer unit. The heat source unit is controlled so as to be larger than the degree of temperature decrease per unit time of the heat transfer unit.

As described above, according to the disclosure of the present invention, the degree of temperature rise of the heat transfer unit in the state where the control unit controls the heating and cooling states of the heat transfer unit by the heat source unit and the heat transfer unit is heated determines the heat transfer unit. Make it larger than the degree of temperature decrease of the heat transfer part in the cooled state, and the temperature increase of the heat transfer part is a sudden change to reach the first predetermined temperature in a short time, while the temperature decrease of the heat transfer part is slow. As a change, by allowing the human body to reach a second predetermined temperature over a longer period of time, the heat transfer section is provided in response to the characteristics that the cold-stimulated receptors in the human body have more characteristics than the warm-stimulated receptors. In the warmed state, the degree of temperature rise is increased, the temperature is quickly reached to a high temperature range to activate the receptors, and the heat stimulus that is difficult to be transmitted to the skin due to the small number of receptors can be surely given to the skin. In addition, in the state where the heat transfer part is cooled, the degree of temperature decrease is relatively small to cool the heat transfer part within the range where the cold stimulus that is easily sensed by the receptor is sufficiently accepted by the skin as compared with the warm stimulus. The burden on the heat source can be reduced. In particular, when the heat source unit is a Pelche element, the degree of generation of exhaust heat generated by heat absorption related to the cooling of the heat transfer unit can be determined by slowing the temperature change even during cooling when the load is generally higher than during heating. By lowering the heat, the heat dissipation load of the exhaust heat can be reduced and heat absorption can be performed reasonably, and the heat transfer portion can be appropriately cooled to surely lower the temperature.

Further, in the beauty device according to the present invention, if necessary, the control unit transfers the heat source unit to the heat source unit for a predetermined time after the heat transfer unit is warmed and before the heat transfer unit is cooled. It executes control to stop energization.

As described above, according to the present invention, a period for stopping the energization to the heat source portion is provided between the state in which the heat source portion warms the heat transfer portion and the state in which the heat transfer portion is cooled, and the first heating of the heat source portion is performed. The heat transfer part that has reached a predetermined temperature is given a state in which the heat source part does not heat or cool, and the heat transfer part gradually lowers the temperature by natural heat dissipation during this energization stop period. As a result, the heat transfer section is kept at a temperature higher than the ambient environment temperature and felt warm for a certain period of time without heating by energizing the heat source section, and the heat transfer section starts from the first predetermined temperature. It is possible to realize a state in which the temperature is gradually lowered without cooling by energizing the heat source portion, and it is possible to suppress the power consumption for the power transfer stop. In addition, the temperature change of the heat transfer part when the heat transfer part shifts from the warmed state to the cooled state can be made into a gradual transition state by sandwiching a slow cooling period accompanying the stoppage of energization, and the temperature can be changed. The irritation to the skin caused by the change can be suppressed. Furthermore, in the heat source section as well, by inserting an energization stop period between the heating state and the cooling state of the heat transfer section, a sudden temperature change can be avoided, the thermal load at the start of cooling can be suppressed, and power consumption can be suppressed. The mechanical stress of the heat source part and the heat transfer part due to the temperature change can be alleviated, and the durability of these heat source parts and the heat transfer part can be improved.

Further, in the beauty device disclosed in the present invention, if necessary, the heat source portion is a Pelche element having front and back surfaces serving as a heat generation surface and a heat absorption surface, and the front surface or the back surface facing the heat transfer portion and the heat transfer portion. It is arranged in the main body as heat transferable to the back surface or the front surface of the heat source part which does not face the heat transfer part, and releases the heat transferred from the heat source part into the ambient atmosphere. A heat radiator that enables heat transfer and a fan that is arranged inside the main body so as to generate an air flow of air taken in from the outside of the main body and apply the air flow to the heat radiator to forcibly cool the radiator. The control unit operates the fan in a state where the heat transfer unit is cooled, and the heat source unit performs heat transfer after the state in which the heat transfer unit is cooled and before the state in which the heat transfer unit is cooled next. The control for operating the fan is executed for the whole or a part of the period in which the part is not cooled.

As described above, according to the disclosure of the present invention, the heat source portion is a Pelche element, a radiator is provided on the side of the heat source portion not facing the heat transfer portion, and the side of the heat source portion facing the heat transfer portion is absorbed by heat. When the heat transfer part is cooled as a surface, the heat generated on the heat generation surface on the opposite side can be released to the outside using a radiator and a fan, preventing overheating on the heat generation side and simultaneously paralleling the heat generation at the heat source part. The heat absorption progresses smoothly so that the heat transfer part can be continuously cooled, and the fan is operated during the period when the heat source part is not cooling the heat transfer part, which is sandwiched between the periods when the heat transfer part is cooled. By forcibly cooling the radiator, the radiator that accepts the heat generated on the heat generating surface of the heat source section and raises the temperature while the heat transfer section is cooled is a fan even after the heat transfer section is cooled. The degree to which the temperature is lowered by forced cooling is increased, and the temperature of the radiator can be significantly lowered when shifting to the state of cooling the next heat transfer part, and the radiator is in the state of cooling the next heat transfer part. The ability to secure sufficient heat capacity to receive heat from the heat source section and increase the amount of heat transferred to the heat generation side by heat absorption in the heat source section, that is, the ability of the heat source section to take heat from the heat transfer section and cool it. It is possible to avoid a situation where the cooling capacity is reduced or cooling cannot be performed due to insufficient heat capacity of the radiator in the state where the next heat transfer part is cooled after the heat transfer part has been cooled. In addition to being able to reliably and continuously apply warm and cold stimuli to the heat transfer part, the temperature of the heat transfer part in the state where the heat transfer part is cooled from the second time onward is appropriately lowered to cool the skin comfortably in the heat transfer part. The condition is obtained and the user does not have to feel the lack of cooling of the skin.

It is configured to include an irradiation unit 18 for irradiating and a control unit 19 for controlling an energization state and the like for each unit of the device.

In the beauty device 1 according to the present embodiment, the head portion 12, the roller portions 16, 17 and the irradiation portion 18 are brought close to or in contact with the user's skin, respectively, and a predetermined beauty-related stimulus is applied to the user. It is provided as a stimulating portion that can be applied to the skin.

The main body 11 has a head portion 12 arranged at one end, while the other end side predetermined length range is a grip portion having a thickness suitable for the user to hold the entire device by hand during use. 11a is formed, and the longitudinal direction of the grip portion 11a and the front direction of the head portion 12 are formed as a shape inclined by a predetermined angle, and the inside thereof is used as an electric circuit such as the control unit 19 or as a power source. A battery (not shown) is arranged.

On the front side of the grip portion 11a, which is closer to the front side of the head portion 12 in the main body portion 11, an operation unit for switching ON / OFF of the operation related to beauty, the type of operation, the strength, etc. in response to the input operation of the user. 11b is arranged. An auxiliary electrode portion 14 made of a conductive member and connected to the control portion 19 is arranged on the back surface side of the grip portion 11a, and when the user grips the grip portion 11a by hand, the hand and the auxiliary electrode portion 14 Will come into contact.
Further, around the head portion 12 in the main body portion 11, a ring-shaped holding portion 12b for holding the porous covering body 12a such as a cotton puff is detachable with respect to the head portion 12.

The operation unit 11b includes a power supply / mode changeover switch 11c that enables selection between operation execution and a power-off state in each of the three operation modes related to beauty, and a temperature change in the head unit 12 that is a heat transfer unit. A temperature change setting switch 11d that can switch the state of the above and a strength changeover switch 11e that switches the strength of the energization current in the energization state to the skin according to each operation mode are arranged.

The head portion 12 is made of a material having conductivity and good thermal conductivity such as metal, and has a convex shape, specifically, three corner portions having a large curvature such as an inflated triangle and a curvature in between of them. It has a trapezoidal shape having a top surface having a contour shape composed of a small curved portion of the above, and is arranged so as to project from the front side of one end of the main body portion 11 with the top surface side as the tip.

A heat source portion 13 is in contact with the head portion 12 from the inside of the main body portion 11 via an insulating material, and the head portion 12 is heated as necessary by the heat source portion 13 to determine the ambient temperature and the body temperature or higher. The configuration is such that the temperature is raised to the temperature or cooled to a predetermined temperature equal to or lower than the ambient temperature. Then, the head portion 12 applies a warm stimulus or a cold stimulus based on the temperature changed by such heating or cooling to the user's skin in a state of being in contact with the user's skin.
Further, the head portion 12 is electrically connected to the control portion 19 in the main body portion 11 and can be energized with the auxiliary electrode portion 14 in the grip portion 11a via the user's body.

When the head portion 12 is used to energize the skin 70, the user holds the grip portion 11a to bring the user's palm, fingers, etc. into contact with the auxiliary electrode portion 14, and the control portion 19 is used to bring the head into contact with the auxiliary electrode portion 14. A voltage is applied between the part 12 and the auxiliary electrode part 14 so that energization can occur, and then the user directly impregnates the head part 12 or impregnates the head part 12 with a liquid agent such as cosmetic water containing an electrolyte component. The skin 70 such as the face is brought into contact with the skin 70 via the covering body 12a. As a result, the head portion 12 and the auxiliary electrode portion 14 can be electrically connected via the user's body, and the skin 70 in contact with the head portion 12 is energized.

Along with the energization of the skin 70 in contact with the head portion 12, the ionic active ingredient contained in the liquid agent such as a lotion that has been applied to the skin surface in advance or impregnated into the porous covering body 12a is provided. Iontophoresis (iontophoresis) introduced into the skin can be executed by ion transfer based on an electric current from the control unit 19. Further, as a cleansing (ion derivation) of the skin 70, a state in which a dirty component such as a charged waste product is transferred from the skin side to the head portion 12 side by energization and taken into the porous covering body 12a held on the surface of the head portion. You can also get it. Such iontophoresis and cleansing methods themselves are known, and detailed description thereof will be omitted.

The heat source portion 13 is arranged in the vicinity of the head portion 12 inside the main body portion 11 and changes the temperature by energization to heat and cool the head portion 12.
Specifically, the heat source portion 13 is a known Pelche element having a thin plate shape, is disposed at the rear portion of the head portion 12 inside the main body portion 11, and has a thin insulating material between the heat source portion 13 and the head portion 12. It is configured to enable good heat conduction between the heat source portion 13 and the head portion 12 while maintaining the insulation between the heat source portion 13 and the head portion 12 by interposing the heat source portion 13.

The heat source unit 13 is electrically connected to the control unit 19 inside the main body unit 11 via a conducting wire, is energized based on the control by the control unit 19, and has a temperature up to a preset temperature with the head unit side as a heat generating surface. It is a mechanism to switch between a state where the temperature is raised and a state where the temperature is lowered to a preset temperature with the head portion side as an endothermic surface. The mechanism of the temperature change of the heat source unit 13 is based on the known Pelche effect, and detailed description thereof will be omitted.

Under the control of the control unit 19, the heat source unit 13 is energized as necessary to change the head unit side to a temperature preset by the control unit 19, thereby causing heat conduction with the head unit 12. The head portion 12 is heated or cooled. Then, the liquid agent impregnated into the skin 70 in contact with the head portion 12 or the porous covering body can be heated or cooled by heat conduction through the head portion 12.

By controlling the energized state of the heat source unit 13 with the control unit 19, not only heating or cooling of the head unit 12 is performed but also heating and cooling are switched in sequence within the time specified as one operation mode. It is feasible.

The Pelche element forming the heat source portion 13 is energized so that the side facing the head portion 12 becomes an endothermic surface, and when the head portion 12 is cooled, heat is not properly dissipated on the heat generating surface on the opposite side where the temperature rises. Since the heat absorption in parallel with the above is also delayed, a mechanism for heat dissipation is installed.

Specifically, it is arranged in the main body 11 so that heat can be conducted to the surface of the heat source 13 that does not face the head portion 12, and heat can be released into the surrounding atmosphere from the heat transmitted from the heat source 13. A fan 13b arranged in the main body 11 so as to generate an air flow of air taken in from the outside of the device 13a and the main body 11 and apply the air flow to the radiator 13a to enable forced cooling of the radiator 13a. It is a configuration including. The fan 13b is electrically connected to the control unit 19 and operates based on the control by the control unit 19.

The tilting arm portion 15 is a substantially arm-shaped member that is tiltably attached to one end of the head portion 12 of the main body portion 11, and the roller portions 16, 17 and the irradiation portion 18 are located at the ends distant from the center of tilting. It is a configuration that can be attached.

The roller portions 16 and 17 are cylindrical bodies made of two conductors, and are arranged at predetermined intervals on the tip side of the tilting arm portion 15 away from the tilting center portion so as to be rotatable about axes parallel to each other. It is a configuration to be installed. Each of the roller portions 16 and 17 is electrically connected to the control portion 19 inside the main body portion 11 via a conducting wire provided in the tilting arm portion 15 to form a pair of electrodes having different polarities.

These roller portions 16 and 17 are exposed so as to be in contact with the skin 70, and in a state of being in contact with the skin 70, the control unit 19 sets the space between the roller portions 16 and 17 to be energized via the skin 70. .. The roller portions 16 and 17 may be formed of a conductor such as metal, or may have a structure formed by attaching a conductor such as metal to the surface of an elastic body such as rubber or arranging a thin film of the conductor.

The irradiation unit 18 is fixed in a region between the two roller portions 16 and 17 on the tip end side of the tilting arm portion 15 so as to be recessed from the roller portions 16 and 17, and the two roller portions 16 and 17 are attached to the skin 70. The irradiation unit 18 faces the skin 70 and can irradiate the skin with light.

Under the irradiation control by the control unit 19, the irradiation unit 18 irradiates visible light in the red region (wavelength of about 620 to 750 nm) and the yellow region (wavelength of about 570 to 590 nm), and also emits visible light in the near infrared region (wavelength of about 800 nm). It irradiates light of ~ 1000 nm).

The irradiation unit 18 employs a known structure in which a known light emitting diode (LED) forming a light source is covered with a translucent cover, and detailed description thereof will be omitted. The irradiation unit 18 is fixed to the tilting arm portion 15 and is electrically connected to the control unit 19 inside the main body portion 11 via a conducting wire provided in the tilting arm portion 15.

The light from the irradiation unit 18 is controlled by the irradiation unit 19 so as to be substantially continuous, that is, continuous light without flicker to the human eye, or intermittently, that is, at a predetermined irradiation intensity. Irradiation is performed so that the irradiation period and the non-irradiation period are alternately repeated.

When energization by the roller portions 16 and 17 and light irradiation from the irradiation portion 18, the tilting arm portion 15 is tilted to position the irradiation portion 18 and the roller portions 16 and 17 in front of the head portion 12, and the roller portion 16 17 is in a state where it can come into contact with the skin 70 (see FIGS. 4, 5, and 6). On the other hand, when energization and light irradiation are not performed by the roller portions 16 and 17 such as iontophoresis, the tilting arm portion 15 is tilted to shift the roller portions 16 and 17 and the irradiation portion 18 from the front of the head portion 12, and the head portion is used. When the 12 is in the open state, the head portion 12 can be covered with a porous covering body or brought into contact with the skin 70 (see FIGS. 1, 2, and 3).

The control unit 19 is built in the main body unit 11, receives an input operation to the operation unit 11b of the user, controls energization to the heat source unit 13, and adjusts the heating / cooling state of the head unit 12 by the heat source unit 13. In addition to being possible, it controls the energization between the head portion 12 and the auxiliary electrode portion 14, the energization between the paired roller portions 16 and 17, and the light irradiation in the irradiation unit 18, respectively.

The control unit 19 sets the operation mode of each part for each beauty application. In this embodiment, the control unit 19 has a cleansing mode for removing harmful components and waste products accumulated on the skin, and a lotion or the like in the deep part of the skin. There are three modes: an iontophoresis mode that permeates the ionic active ingredient to enhance the moist feeling, and a roller energization and light irradiation mode that activates the skin to fix and permeate the milky lotion and cream.

Of the operation modes, in the cleansing mode and the iontophoresis mode, the control unit 19 energizes the space between the head unit 12 and the auxiliary electrode unit 14. In the roller energization and light irradiation mode, the pair of roller portions 16 and 17 are energized, and the irradiation unit 18 is operated to irradiate light.

Further, the control unit 19 sets three types of temperature change states in the head unit for giving a thermal stimulus to the skin from the head unit 12 at the same time as or independently of the iontophoresis mode. Specifically, a hot / cold alternating application mode in which a state in which the head portion 12 is warmed and a state in which the head portion 12 is cooled are alternately generated so that the head portion 12 alternately gives a warm stimulus and a cold stimulus to the skin. A warm stimulus application mode in which the head portion 12 is maintained in a warm state and only the warm stimulus is continuously applied to the skin, and a warm stimulus application mode in which the head portion 12 is maintained in a cool state and only the cold stimulus is continuously applied to the skin. The cold stimulus application mode is set to be selectable.

When the temperature of the head unit 12 is changed in these three modes, the control unit 19 controls the energization state of the heat source unit 13 according to each mode to heat or cool the head unit 12. It becomes.

For example, in the case of the heating / cooling alternating application mode in which the state of heating the head portion 12 and the state of cooling the head portion 12 occur alternately, the control unit 19 appropriately heats and cools the head portion 12 by the heat source unit 13 at a predetermined timing. To make the warm period of the head portion 12 (the period in which the head portion 12 is higher than the ambient temperature) and the cold period (the period in which the head portion 12 is lower than the ambient temperature) have the same length. In addition, the energization of the heat source unit 13 is controlled, and the heat source unit 13 alternately heats and cools the head unit 12. As a result, the user can evenly feel the amount of the warm stimulus and the amount of the cold stimulus given to the skin from the head portion 12.

In addition to this, the control unit 19 operates the fan 13b in a state where the head unit 12 is cooled by the heat source unit 13 so that the heat source unit 13 can cool the head unit 12 without delay. Further, during a period in which the heat source unit 13 does not cool the head portion 12, such as after the head portion 12 is cooled and then before the head portion 12 is cooled, or while the head portion 12 is in the warming state. However, the control unit 19 operates the fan 13b to cool the heat radiation unit 13a.

As a specific example of the control related to the temperature change of the head unit 12, the control unit 19 is a heat source unit when the hot / cold alternating mode is selected as the temperature change state of the head unit 12 when ion introduction is not performed. The head portion 12 is heated by energizing the surface of the head portion 13 so that the surface on the head portion side is on the heat generating side, and the temperature of the head portion 12 is set in the first period from the start of this heating, for example, about 30 seconds. The energization of the heat source unit 13 is controlled so as to shift to the first predetermined temperature, for example, 40 ° C. After this first period, the control unit 19 stops the energization of the heat source unit 13 for the second period, for example, about 15 seconds, puts the heat source unit 13 and the head unit 12 into a natural heat dissipation state, and puts the head unit 12 into a natural heat dissipation state. The temperature of the above-mentioned temperature gradually decreases near the first predetermined temperature for a while.

Subsequently, the control unit 19 energizes the heat source unit 13 so that the surface on the head unit side is on the endothermic side to cool the head unit 12, and a third period from the start of this cooling, for example, about. The energization of the heat source unit 13 is controlled so as to lower the temperature of the head unit 12 to a second predetermined temperature, for example, a temperature about 10 ° C. lower than the ambient temperature in 75 seconds. At the same time, the control unit 19 operates the fan 13b to appropriately release the heat generated on the heat generating side of the heat source unit 13 to the outside through the radiator 13a, and the cooling of the head unit 12 due to the heat absorption by the heat source unit 13 continues. Be able to do it.

After that, the control unit 19 switches the energization state to the heat source unit 13, stops the cooling of the head unit 12 by the heat source unit 13, and makes the surface of the heat source unit 13 on the head unit side again on the heat generation side. The series of control states is repeatedly executed by energizing and heating the head portion 12. However, when the heat source unit 13 heats the head unit 12 for the second time or later, the control unit 19 causes the fan 13b to operate to lower the temperature of the heat radiation unit 13a as much as possible and cool the next head unit 12. You will be prepared for the situation.

The degree of temperature rise and fall of the head portion 12 and the period of the temperature change are different from each other, and the energization to the heat source portion 13 is stopped to provide a period during which the head portion 12 is not actively heated and cooled. By controlling the energization, the head portion 12 can obtain a temperature change state in which the temperature of the head portion 12 is higher than the ambient temperature and the cooling period of which the temperature is lower than the ambient temperature is about 1 minute (see FIG. 12). ), The user can feel the amount of warm stimulus and the amount of cold stimulus given to the skin evenly.

Further, in order to obtain a temperature change state having the same length as the hot period and the cold period in the head unit 12, the control unit 19 is provided with a period for stopping the energization of the heat source unit 13, so that the head unit 12 can be used as a component of the heat source unit. Even if the time required to reach each predetermined temperature of the head is likely to shift due to slight differences in heating and cooling capacities due to individual differences, the shift can be absorbed by adjusting the energization stop period, and the temperature can be increased. The period and the cold period can be set to the same length without difficulty. In addition, since the period for stopping the energization of the heat source unit 13 is provided, the period for cooling the head unit 12 by energizing the heat source unit 13 to lower the temperature can be shortened, and the heat source unit 13 having a large load can be shortened. Power consumption can be suppressed by suppressing the operation related to cooling, and especially when the power supply unit is a battery, the power input for the cooling operation of the heat source unit is suppressed, and the power supply capacity of the battery is maintained to the maximum. The device operating time when using the device can be longer.

Further, while the heat source unit 13 is not cooling the head unit 12, the control unit 19 operates the fan 13b to forcibly cool the radiator 13a, so that the heat source unit 13 is cooled to the heat generating surface of the heat source unit 13. The radiator 13a, which receives the generated heat and raises the temperature, is forcibly cooled by the fan 13b even after the head portion 12 is cooled, and the degree of lowering the temperature is increased to cool the next head portion 12. At the time of transition to the state, a state in which the temperature of the radiator 13a is significantly lowered can be obtained. As a result, a sufficient heat capacity that can receive heat from the heat source portion 13 of the radiator 13a is secured in a state where the next head portion 12 is cooled, and the amount of heat transferred to the heat generating side by the heat absorption in the heat source portion 13 is increased. That is, the ability of the heat source unit 13 to take heat from the head unit 12 and cool it can be increased. In this way, it is possible to avoid a situation in which the cooling capacity is reduced or cooling cannot be performed due to insufficient heat capacity of the radiator 13a in the state where the next head portion 12 is cooled after the head portion 12 has been cooled once. It is possible to reliably and continuously execute the alternate application of stimulation and cold stimulation.

The operation mode of the control unit 19 is switched based on the input operation of the user to the power supply / mode changeover switch 11c of the operation unit 11b. Further, the switching of the three modes of the temperature change state in the head unit 12 is performed based on the input operation of the user to the temperature change setting switch 11d of the operation unit 11b.

When using the beauty device 10, when the user first operates the power / mode changeover switch 11c from the OFF state in which the beauty device 10 is not operating, the control unit 19 performs cleansing mode, iontophoresis mode, roller energization, and light irradiation. One of the modes can be executed, and each time the switch is pressed, the operation of each mode and the four states of power off are sequentially switched.

Further, when the temperature change setting switch 11d is first operated from the OFF state in which the beauty device 10 is not operating, the control unit 19 executes any one of the hot / cold alternating giving mode, the warm stimulating giving mode, and the cold stimulating giving mode. It will be possible. Also in this case, each time the operation of pressing the temperature change setting switch 11d is performed, the control unit 19 sequentially switches between the four states of operation of each mode and power off.

In addition, when the temperature change setting switch 11d is operated while the power supply / mode changeover switch 11c is operated and the iontophoresis mode is selected as the operation mode, the control unit 19 energizes the iontophoresis selected as the operation mode. In parallel with the execution of, the energization control of the heat source unit 13 according to the mode selected by the operation of the temperature change setting switch 11d is executed, and a predetermined temperature change state is given to the head unit 12 in the selected mode. It becomes. In this case, the control unit 19 operates each mode related to the temperature change state of the head unit 12 and energizes the heat source unit 13 each time the temperature change setting switch 11d is operated in parallel with the control related to iontophoresis. The four states of OFF (only iontophoresis is executed) are sequentially switched.

On the other hand, when the cleansing mode, the roller energization, and the light irradiation mode are selected as the operation modes, the subsequent operation of the temperature change setting switch 11d is invalidated, and the operation of each of these modes and the energization of the heat source unit 13 are performed at the same time. There is no execution.

Further, when the control unit 19 energizes between the head unit 12 and the auxiliary electrode unit 14 or between the roller units 16 and 17 corresponding to each operation mode, the current flowing through the user's skin due to this energization is generated. The strength adjustment control will be performed. This adjustment is performed based on the input operation of the user to the strength changeover switch 11e provided in the operation unit 11b, and each time the operation of pressing the strength changeover switch 11e is performed, the control unit 19 sets the strength of four stages of energization. Are switched sequentially.

In this way, the power supply / mode changeover switch 11c of the operation unit 11b can select and switch the operation mode related to energization, and the temperature change setting switch 11d can select and switch the mode related to the temperature change state in the head unit 12. By doing so, the temperature change state mode can be selected independently of the operation mode, and the operation related to energization and the operation related to the head temperature are separated, so that the user can intuitively operate and operability. Excellent for. Further, the temperature change state in the head portion 12 at the time of iontophoresis can also be set by operating the temperature change setting switch 11d after selecting iontophoresis, and can be flexibly set according to the situation at that time, the skin condition, and the like. For example, the temperature can be selected according to the skin condition after the start of iontophoresis, the device operating state more suitable for the user can be obtained, and the comfort and satisfaction after stimulation can be improved. In addition, when only the heating and cooling thermal stimulation is applied from the head portion 12 to the skin, only the temperature change setting switch 11d needs to be operated, and the operation can be made extremely easy.

Next, the operating state of the beauty device according to the present embodiment will be described. As a premise, it is assumed that the user holds the grip portion 11a of the beauty device 1 and points the head portion 12 or the roller portions 16 and 17 toward the skin portion to be used. Then, if the power supply unit (battery) of the beauty device 1 has a sufficient capacity and the mode is selected and input by each switch of the operation unit 11b, the operation of each mode can be performed without difficulty until the end of the preset period. It shall be in a state where it can be continued.

When performing cleansing or iontophoresis using the head portion 12, the user tilts the tilting arm portion 15 in advance to shift the roller portions 16, 17 and the irradiation portion 18 from the front of the head portion 12, and the head portion 12 is the skin 70. (See FIGS. 1, 2, and 3). Then, in the case of cleansing, a wiping lotion or the like containing an electrolyte component is applied directly to the skin, and in the case of iontophoresis, a protective lotion or the like containing an electrolyte component is directly applied to the skin, or a porous coating material such as a cotton puff 12a. It is in a state where this porous coating is held on the head portion 12 by soaking into the head portion 12.

When the user operates the power supply / mode changeover switch 11c of the operation unit 11b to select the cleansing mode (1C) or the iontophoresis mode (2C), specifically, the operation of pressing once from the power-off state is performed. Then, when the cleansing mode is selected or the iontophoresis mode is selected by pressing twice from the power off state, the control unit 19 has a pulse-like weakness between the head unit 12 and the auxiliary electrode unit 14 in a short cycle. It enables the start of an energized state in which a current flows. However, when the head portion 12 is separated from the skin 70, there is no energization because the circuit between the head portion 12 and the auxiliary electrode portion 14 is not closed via the body.

When the user moves the beauty device 10 to be held and brings the head portion 12 into contact with the skin 70 directly or through the porous covering body 12a, the head portion 12 and the auxiliary electrode portion 14 come into contact with the user's body. , It becomes an energized state through a lotion that has been applied to the skin surface in advance or impregnated into a porous coating body. In the case of cleansing, it is possible to remove the dirt on the skin by migrating the charged fine dirt component on the skin surface or inside from the skin side to the porous coating body side (see FIG. 8). Further, in the case of iontophoresis, the ionic active ingredient in the cosmetic water can be transferred to the skin side to allow the active ingredient to permeate into the skin (see FIG. 9).

When the user moves the head portion 12 little by little on the skin while keeping the head portion 12 in contact with the skin 70, the target position for cleansing or iontophoresis can be changed while the head portion 12 is energized. However, when the head portion 12 is separated from the skin 70, the energization is immediately interrupted. When the cleansing and iontophoresis are completely completed, the user may operate the power / mode changeover switch 11c of the operation unit 11b to switch to another operation mode or the power off state. In addition, the control unit 19 may stop energization after a preset time for cleansing or iontophoresis. After the end of these modes, it is desirable for the user to remove the porous coating, if used, from the head 12 and then clean the surface of the head 12 to prepare for the next use. ..

On the other hand, when the iontophoresis is executed while causing a predetermined temperature change in the head portion 12, the iontophoresis is selected by the operation of the power supply / mode changeover switch 11c of the user as described above, and the iontophoresis is used. By operating the temperature change setting switch 11d of the person, the mode of the temperature change state is selected.

In response to the operation of the user, the control unit 19 is in a state where energization can be started in which a weak pulsed current is passed between the head unit 12 and the auxiliary electrode unit 14 in a short cycle. Further, the control unit 19 energizes the heat source unit 13 to start the temperature change of the head unit 12.

When the user operates the temperature change setting switch 11d, specifically, by pressing once from the power off state and selecting the hot / cold alternating application mode, the control unit 19 first has the heat source unit 13 as the head unit. By controlling the 12 to be heated, the head portion 12 is moved to a first predetermined temperature (for example, about 44 ° C.) higher than the ambient air temperature. Further, even when the user selects the temperature stimulus application mode by operating the temperature change setting switch 11d, specifically, by pressing the temperature change setting switch 11d twice from the power off state, the control unit 19 is headed by the heat source unit 13. The head portion 12 is moved to a first predetermined temperature (for example, about 44 ° C.) higher than the ambient temperature by heating the portion 12. On the other hand, when the user operates the temperature change setting switch 11d to specifically press the temperature change setting switch 11d three times from the power off state and selects the cooling stimulus application mode, the control unit 19 first heads at the heat source unit 13. By controlling the unit 12 to be cooled, the head unit 12 is moved to a second predetermined temperature lower than the ambient temperature (for example, a temperature about 10 ° C. lower than the ambient temperature).

Similar to the above, there is no energization when the head portion 12 is separated from the skin 70, but when the user moves the beauty device 10 to bring the head portion 12 into contact with the skin 70 directly or through a porous covering body. The head portion 12 and the auxiliary electrode portion 14 are energized through the user's body and a lotion that has been previously applied to the skin surface or impregnated into a porous coating body. As a result, the ionic active ingredient in the cosmetic water is transferred to the skin side, and the active ingredient can permeate into the skin.

Further, the head portion 12 that comes into contact with the skin 70 directly or through the porous covering body is in a state where the temperature is changed to a temperature different from the ambient environment temperature by heating or cooling the heat source portion 13. There is. As a result, when the head portion 12 is heated, the porous covering body 12a and the skin 70 are warmed by the head portion 12 having an appropriate temperature (first predetermined temperature) higher than the ambient environment temperature. As a result, the activity of the cosmetic water in the porous coating 12a is increased, and the skin 70 is also changed to a state in which the active ingredient can easily permeate, further promoting the transfer of the ionic active ingredient into the skin. In addition, non-electrolyte water-soluble active ingredients and oil-soluble active ingredients in cosmetic water also easily penetrate into the skin 70, and these various active ingredients deeply penetrate into the skin 70 to ensure a cosmetic effect. ..

On the contrary, when the head portion 12 is cooled to lower the temperature, the skin 70 is deprived of heat by the head portion 12 having an appropriate temperature (second predetermined temperature) lower than the ambient temperature. It will be cooled and the temperature will drop, and you will feel the coldness. If iontophoresis is performed in the summer when the ambient temperature is high or when the skin temperature is high after taking a bath, the temperature of the head portion 12 is lowered in this way to perform iontophoresis in a comfortable state. It can be done and gives a feeling of relaxation as well as a beauty effect. Furthermore, although some people may experience discomfort such as pain and itchiness and inflammation of the skin surface due to the energization of the skin due to iontophoresis, the calming effect of cooling the skin causes such discomfort and inflammation. It can be alleviated.

When the user has selected the heating / cooling alternating mode by operating the temperature change setting switch 11d, the heat source unit 13 waits for a predetermined time, for example, 2 minutes after the head unit 12 starts to be heated by the heat source unit. Switches from the state of heating the head portion 12 to the state of cooling the head portion 12, the head portion 12 is cooled and the temperature drops, and the head portion 12 has a second predetermined temperature lower than the ambient environment temperature (for example, the ambient environment). The temperature will shift to about 10 ° C. lower than the temperature). In the first half of iontophoresis in which the head portion 12 is warmed by the head portion 12 in which a warmed state and a cooled state are alternately generated by being heated and then cooled by the heat source portion 13 in this way, the cosmetic water is similarly described above. It is possible to strongly promote the penetration of various active ingredients into the skin 70, and in the latter half of the iontophoresis, the head portion 12 whose temperature has been lowered cools the skin 70 while continuing the iontophoresis, such as in the summer or after taking a bath. Iontophoresis can be performed comfortably even in the above situation, and it is possible to promote the penetration of active ingredients and improve comfort without difficulty. Further, the skin 70 in contact with the head portion 12 is cooled to lower the temperature, so that the skin 70 is tightened, and the active ingredient once permeated into the skin is fixed without escaping to the outside, and their effects can be enhanced.

At the time of such iontophoresis, if the user moves the head portion 12 little by little on the skin while keeping the head portion 12 in contact with the skin 70, the target position of the ion introduction can be changed while the energized state is maintained, and the head portion 12 warms the head portion 12 together. The position of the skin to be or cooled will also change. However, when the head portion 12 is separated from the skin 70, the energization related to iontophoresis is immediately interrupted.

When the iontophoresis accompanied by the temperature change of the head unit 12 is completely completed, the user can operate the power supply / mode changeover switch 11c of the operation unit 11b to switch to another operation mode or the power off state. Just do it. In addition, when the preset time for iontophoresis has passed, the control unit 19 stops the energization between the head unit 12 and the auxiliary electrode unit 14, and also stops the energization to the heat source unit 13, resulting in iontophoresis and the head unit. The temperature change of 12 ends. After completion, it is desirable that the user removes the porous coating body from the head portion 12 when used, and then cleans the surface of the head portion 12 to prepare for the next use.

When energizing the rollers and irradiating light, the user tilts the tilting arm portion 15 so that the roller portions 16 and 17 and the irradiation portion 18 are located on the front side of the head portion 12, and the roller portions 16 and 17 are the skin 70. (See FIGS. 4, 5, and 6). At the same time, apply milky lotion or cream to the skin and let it blend in.

When the user operates the power / mode changeover switch 11c of the operation unit 11b, specifically, presses the power / mode changeover switch 11c three times from the power off state to select the roller energization and light irradiation mode (3C), the control unit 19 Allows the start of an energized state in which a weak pulsed current is passed between the paired roller portions 16 and 17 in a short cycle, and the irradiation of light in the irradiation portion 18 is also started. However, in a state where the roller portions 16 and 17 are separated from the skin 70, there is no energization because the circuit between the roller portions 16 and 17 is not closed through the skin (skin). In this roller energization and light irradiation mode, the operation of the temperature change setting switch 11d is invalid, and even if the operation is performed, the heat source unit 13 does not heat or cool the head unit 12.

When the roller portions 16 and 17 are brought into close contact with the skin 70 (see FIG. 10), an energized state is established through the skin between the paired roller portions 16 and 17, and the skin is stimulated by the energization to activate the skin and milky lotion. And will promote the penetration of cream. In addition, the skin receives light of an appropriate irradiation intensity from the irradiation unit 18, and the beauty effect of the light is also produced.

If the rollers 16 and 17 are rolled while being in contact with the skin 70 and gradually moved on the skin, the target positions of energization and light irradiation can be changed, but the energization is interrupted or the energization and irradiation positions are changed. Therefore, when the roller portions 16 and 17 are separated from the skin 70, the energization between the roller portions is immediately interrupted. When the energization and irradiation are completely completed, the user can switch to another operation mode or the power off state with the power / mode changeover switch 11c of the operation unit 11b, so that the energization and irradiation unit 18 between the roller units 16 and 17 can be completed. Irradiation of light in is stopped.

In addition, when only heat and cold thermal stimulation is applied from the temperature-changed head portion 12 to the skin, the user tilts the tilting arm portion 15 in advance to tilt the roller portions 16, 17 and the irradiation portion 18. Is displaced from the front of the head portion 12 so that the head portion 12 can be brought into contact with the skin 70 in an open state (see FIGS. 1, 2, and 3). If necessary, the skin 70 is soaked with a milky lotion, cream, or the like.

When the temperature change state in the head unit 12 is selected from the three modes by operating the temperature change setting switch 11d from the power off state of the user, the control unit 19 energizes the heat source unit 13 and the head unit 12 The heating or cooling of the head is started to change the temperature of the head part. In this case, the energization between the head portion 12 and the auxiliary electrode portion 14 is not performed.

When the user moves the beauty device 10 to be held and brings the head portion 12 into contact with the skin 70, heat conduction occurs between the head portion 12 and the skin (see FIG. 11). As a result, the skin is given a thermal stimulus according to the selected temperature change state.

When the user operates the temperature change setting switch 11d, specifically, the operation of pressing the temperature change setting switch 11d once from the power off state to select the heating / cooling alternating application mode, the heat source unit 13 of the control unit 19 is used. A state in which the head portion 12 is controlled to be heated to shift the head portion 12 to a first predetermined temperature (for example, about 40 ° C.) higher than the ambient temperature, and a heat source portion 13 is controlled to cool the head portion 12. Then, the state of shifting the head portion 12 to a second predetermined temperature lower than the ambient environment temperature (for example, a temperature about 10 ° C. lower than the ambient environment temperature) is alternately repeated (see FIG. 12).

Specifically, the control unit 19 first energizes the heat source unit 13 so that the surface on the head unit side is on the heat generation side to heat the head unit 12. The control unit 19 causes the temperature of the head unit 12 to reach the first predetermined temperature, for example, 40 ° C. within a preset first period, for example, about 30 seconds from the start of this heating, and further. After reaching the first predetermined temperature, this temperature is maintained. Then, after the lapse of the first period, the control unit 19 stops the energization of the heat source unit 13 for the second period, for example, 15 seconds, and heats (and cools) the head unit 12 by the heat source unit 13. Instead, the heat source unit 13 and the head unit 12 are put into a natural heat dissipation state. During the second period during which the energization is stopped, the temperature of the head portion 12 begins to gradually decrease from the first predetermined temperature.

Subsequently, the control unit 19 cools the head unit 12 by energizing the fan 13b so that the surface of the heat source unit 13 on the head unit side is on the endothermic side. The control unit 19 cools the head unit 12 to a second predetermined temperature, specifically the ambient environment, by cooling by the heat source unit 13 within a preset third period, for example, 75 seconds from the start of this cooling. The temperature is lowered to a predetermined temperature (for example, 10 ° C.) lower than the temperature, for example, 15 ° C. when the temperature of the indoor air as the ambient temperature is 25 ° C.

After the lapse of the third period for cooling the head unit 12, the control unit 19 switches the energization state to the heat source unit 13 again, stops the cooling of the head unit 12 by the heat source unit 13, and renews the heat source unit 13. The head portion 12 is heated in the same manner as described above by energizing the head portion 12 so that the surface on the head portion side is on the heat generating side, and the series of temperature control states is repeatedly executed again.

However, regarding the second heating of the head portion 12 by the heat source portion 13, the temperature of the head portion 12 at the start of heating is the second predetermined temperature reached by the previous cooling, and the first head portion 12 Since the temperature is different from the temperature at the start of heating, the control unit 19 changes the control parameter related to the temperature rise of the head unit 12 with respect to the heat source unit 13, adjusts the degree of temperature rise of the head unit 12, and heats the head unit 12. As in the case of the first heating of the head portion 12 from the start, the temperature of the head portion 12 is brought to the first predetermined temperature within the first period, and the temperature is higher than the ambient temperature of the head portion 12. The high temperature period is constant regardless of the number of times the head portion 12 is heated so that the user can evenly feel the amount of thermal stimulation given to the skin. In addition, when the heat source unit 13 heats the head unit 12 for the second time, the control unit 19 operates the fan 13b to significantly raise the temperature of the front head unit 12 while cooling the radiator 13a. The temperature of the head portion 12 is significantly lowered by forced cooling by the fan 13b, and then the head portion 12 is shifted to the cooling state for the second time. Therefore, the amount of heat transferred from the head portion 12 to the radiator 13a through the heat source portion 13 by sufficiently securing a heat capacity capable of receiving the heat from the heat source portion 13 of the radiator 13a even when the head portion 12 is cooled for the second time. It is possible to avoid a situation where the cooling capacity is lowered or cooling cannot be executed, such as when the radiator temperature is high and the heat capacity cannot be secured while the head portion 12 is cooled. It is possible to proceed with the application of hot and cold stimuli based on the mode without any problem.

Then, after the second cooling of the head portion 12 is executed (4 minutes after the first heating start), the control unit 19 stops the energization of the heat source portion 13 and stops the cooling of the head portion 12 by the heat source unit 13. After that, when the heat source unit 13 and the head unit 12 naturally raise the temperature to the ambient environment temperature due to the influence of the surroundings, the temperature change of the head unit 12 related to the heating / cooling alternating application mode ends.

It is the first time that the control unit 19 controls to alternately generate a state in which the head portion 12 is warmed to give a warm stimulus to the skin and a state in which the head portion 12 is cooled to give a cold stimulus to the skin. Since the heat source unit 13 and other states differ between when the head unit 12 is heated and cooled and when the head unit 12 is heated and cooled for the second time, the control unit 19 is the first head unit 12. The control content is changed between the control for heating and cooling of the head portion 12 and the control for the second heating and cooling of the head portion 12, so that the repeated hot period and cold period have the same length regardless of the number of times. ing.

Specifically, due to the characteristics of the heat source unit 13 which is a Pelche element, the amount of heat generated when cooling the head unit 12 is large, and the temperature of the radiator rises after the first cooling of the head unit 12 in the heat source unit 13. Even if the 13a is forcibly cooled by the fan 13b, the temperature of the radiator 13a at the start of cooling of the second head portion 12 cannot be lowered to the temperature at the start of cooling of the first head portion 12. Therefore, since the radiator temperature at the start of cooling is high, heat transfer from the heat source unit 13 to the radiator 13a is unlikely to occur in the second cooling of the head unit 12 by the heat source unit 13, and the heat source unit 13 is accompanied by heat absorption. Since the heat generated in the above cannot be radiated smoothly, the degree of temperature drop of the head portion 12 becomes smaller than that of the first cooling of the head portion 12.

Based on this, the control unit 19 determines the timing at which the heated head unit 12 reaches the peak (maximum value) of the temperature change, that is, the maximum temperature, and the cooled head unit during the second heating and cooling of the head unit 12. 12 is controlled so as to accelerate the timing at which the peak (minimum value) of the temperature change, that is, the minimum temperature is reached. On the other hand, in the control unit 19, when the heated head unit 12 is heated and cooled for the first time, the timing at which the heated head unit 12 reaches the peak (maximum value) of the temperature change, that is, the maximum temperature, and the cooled head unit 12 are set. Control is performed so that the peak (minimum value) of the temperature change, that is, the timing of reaching the minimum temperature is delayed from the case of the second heating and cooling, respectively. As a result, the control unit 19 delays the generation of the first cooling period of the head unit 12 based on the cooling of the head unit 12 by the first heating and cooling of the head unit 12 by the heat source unit 13, and makes the cooling period appropriate. The length can be kept to a minimum and at the same time the length of the previous warm period can be adjusted so that the hot period and the cold period have the same length. In addition, in the second heating and cooling of the head unit 12 by the heat source unit 13, the control unit 19 cools the head unit 12 in a state where the degree of temperature decrease of the head unit 12 is smaller than that of the first time because the peak timing is advanced. However, the cooling period of the second head portion 12, which occurs from the latter half of the second cooling period to the natural rise period of the temperature after the cooling is stopped, can be secured sufficiently long, and the second head portion 12 before that can be secured sufficiently. The warm period can be suppressed to an appropriate length, and as a result, the first and second temperature periods and the cold period can be reliably adjusted and controlled to the same length (see FIG. 13).

In this hot / cold alternating mode, there are two types of heat conduction between the head portion 12 and the skin that are in contact with each other, one that is directed from the head portion 12 to the skin 70 and one that is directed from the skin to the head portion 12. A warm stimulus due to heat transfer from the hot head portion 12 to the skin and a cold stimulus due to the deprivation of the skin heat to the low temperature head portion 12 occur alternately, and each of the hot and cold stimuli is alternately given. By repeating the condition, that is, the condition that causes a large temperature change that cannot occur in the skin under normal circumstances, the effect of promoting blood circulation and metabolism in the skin by the warm stimulus, the effect of tightening the skin by the cold stimulus, etc. Not only the effect on the skin of each stimulus, but also the effect of promoting blood circulation and recovering from fatigue based on the alternating heating and cooling of the muscles directly under the skin. In addition, it is possible to obtain a tension-relieving effect similar to that when massaging muscles, eliminating slack in the skin, and especially in the face, the synergistic effect on the skin and muscles is expected to lift up similar to face massage. can. In addition, such an effect can be efficiently obtained only by applying the temperature-changing head portion 12 to the skin, which is also excellent in terms of user-friendliness.

Further, the energization to the heat source portion 13 is controlled so that the degree of temperature rise of the head portion 12 when the head portion 12 is warmed is larger than the degree of temperature decrease of the head portion 12 when the head portion 12 is cooled, and the head portion 12 is controlled. The temperature rise of the head portion 12 is a rapid change to reach the first predetermined temperature in a short time, while the temperature decrease of the head portion 12 is a slow change to reach the second predetermined temperature over a longer period of time. Therefore, in response to the feature that the number of receptors that receive cold stimulation in the human body is larger than that of receptors that receive warm stimulation, the degree of temperature rise is increased when the head portion 12 is warmed, and the temperature is quickly reached to a high temperature range. It activates the receptors and can reliably and for as long as possible give the skin a thermal stimulus that has few receptors and is difficult to transmit to the skin. Then, in the state where the head portion 12 is cooled, the degree of temperature decrease is relatively reduced within a range in which the cold stimulus that is easily sensed by the receptor is sufficiently accepted by the skin as compared with the thermal stimulus, that is, when the head portion is heated. By slowing down the temperature change during cooling of the head portion, which has a higher load, the degree of generation of exhaust heat generated by the heat absorption related to the cooling of the head portion 12 in the heat source portion 13 which is a Pelche element is reduced, and the exhaust heat is exhausted. The heat dissipation load can be reduced to allow heat absorption to be performed reasonably, and the head portion 12 can be appropriately cooled to surely lower its temperature.

In addition, a period is provided between the state in which the heat source unit 13 warms the head unit 12 and the state in which the head unit 12 is cooled to stop the energization of the heat source unit 13 (see FIG. 12), and during this energization stop period. By allowing the head portion 12 to gradually and gradually lower the temperature due to natural heat dissipation, the state where the head portion 12 is higher than the ambient temperature and is at a temperature that is felt to be warm is accompanied by heating by energizing the heat source portion 13. It is possible to realize a state in which the head unit 12 gradually lowers the temperature from the first predetermined temperature without cooling by energizing the heat source unit 13 without holding the heat source unit 13 for a certain period of time. It can be suppressed. Further, the temperature change of the head portion 12 when the head portion 12 shifts from the warmed state to the cooled state can be made into a gradual transition state by sandwiching a slow cooling period accompanying the stoppage of energization, and the temperature can be changed. The irritation to the skin caused by the change can be suppressed. Further, also in the heat source unit 13, by inserting an energization stop period between the heating state and the cooling state of the head unit 12, sudden temperature changes can be avoided, and the thermal load at the start of cooling is suppressed to suppress power consumption. At the same time, the mechanical stress of the heat source unit 13 and the head unit 12 due to the temperature change can be alleviated, and the durability of the heat source unit 13 and the head unit 12 can be enhanced.

Further, when the user operates the temperature change setting switch 11d, specifically, the operation of pressing the temperature change setting switch 11d twice from the power off state to select the temperature stimulus applying mode, the control unit 19 may perform the operation. The heat source unit 13 is controlled to heat the head unit 12, and the head unit 12 is moved to a predetermined temperature higher than the ambient temperature. Specifically, the control unit 19 energizes the heat source unit 13 so that the surface on the head unit side is on the heat generation side to heat the head unit 12, and sets the temperature of the head unit 12 to the first predetermined temperature. The temperature is reached to, for example, 40 ° C., and this temperature is maintained after reaching the first predetermined temperature.

When the head portion 12 whose temperature has been raised by the heat source portion 13 is brought into close contact with the skin 70, the skin and cream are in a state of being warmed, and the user moves the main body portion 11 while pressing the head portion 12 against the skin 70 to move the skin. Warm up. At this time, if the skin 70 is massaged by the head portion 12 and the skin is warmed while being massaged, the massage effect is enhanced. By warming the skin, blood circulation and metabolism of the skin can be promoted, and the warm stimulus given to the skin changes the condition so that the skin can be easily absorbed. The active ingredient inside will penetrate smoothly, and the beauty effect will be further enhanced.

When finishing the application of the temperature stimulus to the skin based on the temperature change of the head portion 12, the user separates the head portion 12 from the skin 70 and operates the temperature change setting switch 11d of the operation portion 11b to perform another mode. The power may be switched to the OFF state. In addition, after a predetermined period set in advance, for example, about 3 minutes, has elapsed from the start of heating of the head portion 12 by the heat source unit 13, the control unit 19 stops energizing the heat source unit 13 and the head unit 13 stops energizing the head unit 13. The heating of the unit 12 is stopped, and the temperature change of the head unit 12 related to the thermal stimulus applying mode ends. After completion, it is desirable for the user to clean the surface of the head portion 12 to prepare for the next use.

If the temperature of the head unit 12 is not changed based on other modes after the power supply to the heat source unit 13 is stopped, the heat source unit 13 and the head unit 12 naturally lower the temperature to the ambient temperature due to the influence of the surroundings. It becomes.

Further, when the user operates the temperature change setting switch 11d, specifically, the operation of pressing the temperature change setting switch 11d three times from the power off state to select the cooling stimulus applying mode, the control unit 19 may perform the operation. The heat source unit 13 controls the head unit 12 to cool the head unit 12, and causes the head unit 12 to shift to a predetermined temperature lower than the ambient air temperature. Specifically, the control unit 19 energizes the heat source unit 13 so that the surface on the head unit side is on the heat absorbing side to cool the head unit 12, and sets the temperature of the head unit 12 to a second predetermined temperature. The temperature, specifically, a temperature lower than the ambient temperature by a predetermined temperature (for example, 10 ° C), for example, 15 ° C when the temperature of the indoor air as the ambient temperature is 25 ° C, is further lowered to a second predetermined temperature. Try to maintain this temperature after reaching it.

When the head portion 12 whose temperature has been lowered by the heat source portion 13 is brought into close contact with the skin 70, the skin is cooled, and the user moves the main body portion 11 while pressing the head portion 12 against the skin 70 to move the skin. cool. In a region near the skin 70, for example, a portion of the skin 70 that comes into contact with the head portion 12, the head portion 12 is indirectly affected by blood circulation or the like, and the temperature drops. In this way, the skin 70 in contact with the low temperature head portion 12 and its surroundings is cooled, so that the skin 70 is tightened, and the active ingredient once permeated into the skin by iontophoresis or the like performed before this is released to the outside. It can be immobilized to enhance the effect based on those components.

Further, if the head portion 12 having a lowered temperature is applied to the skin in the summer when the ambient temperature is high or after the bath where the skin temperature is high, the excessive heat of the skin is cooled and the skin becomes comfortable and calm. You will be able to get a feeling of relaxation, and you will be able to properly perform other cosmetic work on the skin after that.

When the application of the cold stimulus to the skin based on the temperature change of the head portion 12 is finished, the user separates the head portion 12 from the skin 70 and operates the temperature change setting switch 11d of the operation portion 11b to switch to another mode or turn off the power. You just have to switch to the state. In addition, when a preset predetermined period, for example, about 3 minutes has elapsed from the start of cooling of the head portion 12 by the heat source unit 13, the control unit 19 stops energizing the heat source unit 13 and the head unit 13 stops energization. The cooling of the unit 12 is stopped, and the temperature change of the head unit 12 related to the cooling stimulus applying mode ends. After completion, it is desirable for the user to clean the surface of the head portion 12 to prepare for the next use.

If the temperature of the head unit 12 is not changed based on other modes after the power supply to the heat source unit 13 is stopped, the heat source unit 13 and the head unit 12 naturally raise the temperature to the ambient temperature due to the influence of the surroundings. It becomes.

As described above, in the beauty device according to the present embodiment, the head portion 12 as a heat transfer unit that changes the temperature and gives a stimulus based on the temperature to the skin is arranged, and is based on the energization control by the control unit 19. A heat source unit 13 for heating and cooling the head unit 12 is provided, and the control unit 19 controls the temperature of the heat source unit 13 in a state where the head unit 12 is close to or in contact with the skin of the user, and the heat source unit 13 is provided. The state where the head portion 12 is warmed and the state where the head portion 12 is cooled occur alternately, and the head portion 12 continuously gives the skin a warm stimulus and a cold stimulus, so that the head portion 12 transfers the heat stimulus to the skin. The cold stimulus is subsequently applied after the warm stimulus, and the discomfort that may occur due to the preceding warm stimulus being applied to the skin can be alleviated and suppressed by the subsequent cold stimulus, and the head portion 12 The effect of the stimulus associated with the temperature change and the synergistic effect of being executed at the same time as the ion introduction can be appropriately and appropriately given to the skin. Further, when the warm stimulus and the cold stimulus are alternately applied to the skin by the head portion 12, for example, a switching operation by the user of each operation mode for executing the warm stimulus application and the cold stimulus application, and the thermal stimulus application and the cold stimulus application are performed. It is not necessary to operate the device to replace each stimulus-giving portion and bring it into contact with the skin, and the stimulating state can be easily obtained, so that the user does not feel the troublesome operation.

Further, the control unit 19 controls the heating and cooling states of the head unit 12 by the heat source unit 13, and the temperature period in which the head unit temperature is higher than the ambient environment temperature and the cooling period in which the head unit temperature is lower than the ambient environment temperature are time. By balancing warm and cold stimuli, the effect of one stimulus given on the skin covers the effect on the skin of the less stimulus. It is possible to prevent it from being hidden and inconspicuous, and the user can evenly feel the amount of warm stimulus and the amount of cold stimulus given to the skin from the head portion 12, resulting in discomfort and irritation due to the difference in the amount of stimulus. An appropriate stimulus-giving state can be obtained without causing a feeling of excess or deficiency. In particular, by alternately applying the same degree of warm and cold stimuli to the skin from the head portion 12, a large temperature change that cannot occur in a normal situation is caused on the skin, and a change in blood flow is promoted. By changing the tension of the muscles under the skin, the sagging of the skin can be eliminated, so-called lift-up.

In the beauty device according to the embodiment, the outer shapes of the roller portions 16 and 17 are formed in a simple cylindrical surface shape, but the present invention is not limited to this, and the contact area between the roller portion and the skin is secured. As long as the energization performance to the skin can be guaranteed, the roller portion can be formed as a shape having irregularities on the surface thereof, and when the roller portion and the skin are brought into contact with each other, the contact directly to the skin. It is possible to give a kind of massage effect by promoting the further generation of stimuli. For example, when the roller portion is rolled as a rotationally symmetric body having an outer shape having a plurality of irregularities while the roller portion is in contact with the skin, the skin is pressed intermittently and the skin is repeatedly tapped with a finger. It can also be configured to give a stimulus such as a so-called tapping massage.

Further, in the beauty device according to the embodiment, the second predetermined temperature as the target temperature of the head portion 12 in the state where the head portion 12 is cooled by the heat source portion 13 is a predetermined temperature (for example, a predetermined temperature) from the ambient environment temperature in the control unit 19. It is configured to be set to a low temperature (10 ° C), and this second predetermined temperature is treated as a preset fixed value, regardless of the temperature condition of the ambient environment. The control can be simplified and is preferable in terms of cost, but the present invention is not limited to this, and the temperature difference between the second predetermined temperature and the ambient temperature can be controlled to be changed according to the ambient temperature. For example, when the ambient temperature is low as in winter, if the head is cooled by simply keeping the temperature difference from the ambient temperature of the second predetermined temperature as the initial setting, the head is excessively cooled. In a situation that causes discomfort to the user, the degree of temperature drop of the head part is suppressed, that is, the temperature difference between the second predetermined temperature and the ambient temperature is brought into contact with the skin of the head part. The temperature may be adjusted and controlled so as to keep the temperature small while maintaining the state in which the user feels cold at the time. As a result, the excessive temperature difference between the head portion and the skin can be alleviated, and discomfort and discomfort when the skin touches the head portion can be suppressed. Further, as a result of controlling so as to suppress the cooling of the head portion by the heat source portion, the power consumption of the power supply portion related to the cooling can be suppressed by not performing cooling more than necessary, and the device usage time can be extended.
