This application is based on Japanese Patent Application No. 2017-94025 filed on May 10, 2017 and Japanese Patent Application No. 2018-60089 filed on March 27, 2018. The description is incorporated by reference.

The present disclosure relates to a beauty device that warms the skin of a human body.

Patent Document 1 discloses an exothermic beauty pack used for facial thermal beauty. This exothermic beauty pack is a sheet-like mask having exothermic properties. This pack contains lotion. This pack is used in close contact with this face. As the pack itself generates heat, penetration of the skin lotion is improved.

No. 2014-129313

The present inventor examined a beauty device for heating the skin with radiant heat. This beauty device includes a film-like heater layer and a space forming member. The heater layer is disposed so as to face the skin across the space and emits radiant heat toward the skin. The space forming member is disposed on the skin side of the heater layer, and forms a space between the heater layer and the skin. According to this beauty device, the skin can be heated by radiant heat from the heater layer without bringing the heater layer into contact with the skin.

As a method of using this beauty device, a method of warming the skin with this beauty device with a lotion applied to the skin can be considered. As another method of use, a method of heating the skin with this cosmetic device in a state where a non-pyrogenic pack containing skin lotion is attached to the skin can be considered.

However, when using the pack, radiant heat is blocked by the pack. For this reason, when the temperature of the heater layer is the same when the pack is used and when it is not used, the temperature of the skin is lower when the pack is used than when the pack is not used. Therefore, this inventor discovered that the subject that the temperature of a user's skin did not become an appropriate temperature for the penetration of skin lotion arises.

In addition, an object with a fixed shape blocks radiant heat. For this reason, this problem is not limited to the case of using a pack containing skin lotion, but is a problem that occurs in the case of using an object containing a cosmetic liquid. Beauty means preparing the skin beautifully. Cosmetic liquids generally include liquids such as lotions, milky lotions, and cosmetic liquids. Moreover, the liquid contained in vegetables and fruits is also included. Liquids of ingredients such as honey and yogurt are also included. Therefore, when a sliced vegetable or fruit is applied to the skin, the vegetable or fruit corresponds to the object.

This disclosure is intended to provide a beauty device that can heat a user's skin so that the temperature of the user's skin becomes an appropriate temperature.

In order to achieve the above object, according to one aspect of the present disclosure, a beauty device comprises:
A film-like heater layer that is disposed facing the skin across the space and emits radiant heat toward the skin;
A space forming member disposed on the skin side of the heater layer and forming a space between the heater layer and the skin;
A determination unit for determining the presence or absence of an object on the skin;
A temperature control unit for controlling the temperature of the heater layer,
The object has a fixed shape on the skin that does not deform unless force is applied, and contains a cosmetic liquid inside.
When the determination unit determines that there is an object, the temperature control unit increases the temperature of the heater layer as compared to the case where the determination unit determines that there is no object.

According to this, even when there is an object on the skin, the user's skin can be heated so that the temperature of the user's skin becomes an appropriate temperature.
Reference numerals in parentheses attached to each component and the like indicate an example of a correspondence relationship between the component and the like and specific components described in the embodiments described later.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following embodiments, parts that are the same or equivalent to each other will be described with the same reference numerals.

(First embodiment)
As shown in FIGS. 1 and 2, the beauty device 10 of the present embodiment is worn on the face 2 of the user 1. The beauty device 10 warms the skin of the face 2 by radiant heat. That is, the beauty device 10 applies heat to the face 2 from outside the body. The beauty device 10 includes a mask body 12 and a headband 14. The mask main body 12 covers the face 2 of the user 1 when it is arranged to face the face 2 of the user 1. The headband 14 is a fixing member that fixes the mask main body 12 to the face 2 that is an object to be heated. The headband 14 is put on the head. As a result, the mask main body 12 is fixed to the face 2 of the user 1.

As shown in FIG. 3, the mask main body 12 includes a half mirror layer 16, a heater unit layer 18, and a pad 20.

The half mirror layer 16 is an exterior member of the mask body 12. As shown in FIG. 2, the half mirror layer 16 is laminated on the non-user side of the heater unit layer 18. The half mirror layer 16 has a shape and size that can cover the heater unit layer 18. That is, the half mirror layer 16 has a shape and size that can cover the face 2. Although not shown, the half mirror layer 16 has a transparent member such as a resin material and a surface layer in which a metal material such as aluminum is deposited on the surface of the transparent member.

The half mirror layer 16 is light transmissive. For this reason, the user 1 can see around the user 1 when the beauty device 10 is worn. More specifically, when the space on one side of the half mirror layer 16 is bright and the space on the other side is dark, part of the light from the bright side is reflected by the half mirror layer 16 and other light from the bright side is reflected. Some are transparent. Thus, when the half mirror layer 16 is viewed from the bright side, the half mirror layer 16 functions as a mirror. When the half mirror layer 16 is viewed from the dark side, the half mirror layer 16 functions as a translucent member where the bright side can be seen. When the mask main body 12 is mounted, the user side of the mask main body 12 is a dark side, and the non-user side of the mask main body 12 is a bright side. For this reason, when the mask main body 12 is mounted, the user 1 can see around the user 1, but a person other than the user 1 cannot see the face of the user 1.

The heater unit layer 18 is a heater device having a film-like heater layer. The heater unit layer 18 is laminated on the inner side of the half mirror layer 16, that is, on the user side. The heater unit layer 18 has a shape and a size that can cover the face 2. In the heater unit layer 18, two openings 18 a are formed at positions corresponding to the eyes of the user 1 when the mask main body 12 is mounted. Each of the two openings 18a is a space. For this reason, the heater unit layer 18 covers the forehead, nose, mouth, cheek, chin, and the like of the user 1 when the mask main body 12 is mounted. The heater unit layer 18 generates heat by energization and emits radiant heat toward the face 2 of the user 1. Details of the heater unit layer 18 will be described later.

The pad 20 is a space forming member that forms a space 3 between the heater unit layer 18 and the skin of the face 2 as shown in FIG. As shown in FIG. 3, the pad 20 has a ring shape along the contour of the face 2. The pad 20 is laminated on the user side of the heater unit layer 18, that is, on the skin side, and over the entire periphery of the heater unit layer 18. As shown in FIG. 2, when the mask main body 12 is mounted, the pad 20 contacts the entire peripheral edge of the face 2 of the user 1. The pad 20 is made of a foamed resin material such as foamed urethane. Note that the pad 20 may be made of another material having cushioning properties and sealing properties.

The heater unit layer 18 does not directly touch the face 2 of the user 1 when the mask main body 12 is mounted by the pad 20. Further, since the pad 20 has an annular shape, a closed space 3 is formed between the heater unit layer 18 and the face 2 when the mask main body 12 is mounted.

The pad 20 is provided with two band fixing portions 201. Each of the two end portions 141 of the headband 14 is fixed to each of the two band fixing portions 201.

As shown in FIG. 4, the heater unit layer 18 includes a heater body layer 22, a heat insulating layer 24, and a skin layer 26. The heater body layer 22 is a film-like heater layer that generates heat by energization and emits radiant heat toward the skin of the face 2. The size of the heater body layer 22 in the surface direction is the same as the size of the heater unit layer 18 in the surface direction. That is, the heater main body layer 22 is disposed over the entire area of the heater unit layer 18 in the surface direction.

The heat insulating layer 24 is laminated on the heater main body layer 22 on the side opposite to the user, that is, on the half mirror layer 16 side. The heat insulating layer 24 is a layer that suppresses heat transfer from the heater body layer 22 to the half mirror layer 16 side. The heat insulation layer 24 suppresses the outflow of heat from the heater body layer 22 to the half mirror layer 16 side.

The skin layer 26 is laminated on the user side of the heater body layer 22. The skin layer 26 is a layer for protecting the heater body layer 22. The skin layer 26 is a layer for ensuring the design of the heater body layer 22 on the user side. The skin layer 26 is made of a cloth such as a woven fabric or a non-woven fabric.

As shown in FIGS. 5 and 6, the heater main body layer 22 includes a substrate portion 30, a pair of

electrodes

32 and 34, and a plurality of heat generating portions 36. The X-axis direction, the Y-axis direction, and the Z-axis direction indicated by arrows in the figure are directions orthogonal to each other. The X-axis direction and the Y-axis direction are directions parallel to the surface of the heater main body layer 22, that is, the surface direction of the heater main body layer 22. The Z-axis direction is the thickness direction of the heater body layer 22.

The substrate unit 30 is in the form of a film. A pair of

electrodes

32 and 34 and a plurality of heat generating portions 36 are disposed inside the substrate portion 30. The substrate part 30 is made of a flexible synthetic resin as an insulating material. The synthetic resin is, for example, a thermoplastic resin.

Each of the pair of

electrodes

32 and 34 extends linearly along the Y-axis direction. The pair of

electrodes

32 and 34 are disposed away from each other in the X-axis direction. The pair of

electrodes

32 and 34 are electrically connected to the plurality of heat generating portions 36.

The plurality of heat generating portions 36 generate heat by energization and radiate radiant heat. The plurality of heating portions 36 are made of a metal material. The plurality of heat generating portions 36 are arranged in parallel between the pair of

electrodes

32 and 34. One heat generating portion 36 extends linearly along the X-axis direction between the pair of

electrodes

32 and 34. One end side of one heat generating portion 36 is electrically connected to one electrode 32. The other end side of the first heat generating part 36 is electrically connected to the other electrode 34 of the pair of

electrodes

32, 34. As shown in FIG. 6, the one heat generating part 36 is film-shaped.

As shown in FIG. 5, a low heat conduction portion 37 exists between two adjacent heat generating portions 36 among the plurality of heat generating portions 36 inside the substrate portion 30. The low thermal conductive portion 37 is a portion having lower thermal conductivity than the heat generating portion 36. The low heat conducting portion 37 thermally separates the adjacent heat generating portions 36 from each other. The low heat conducting portion 37 is made of an insulating material that constitutes the substrate portion 30.

Thus, the heater main body layer 22 has a plurality of heat generating portions 36 that are film-like and a plurality of low heat conducting portions 37. Since the heat generating part 36 is in the form of a film, the heat capacity of the heat generating part 36 is reduced.

Furthermore, a heat generating part that generates heat and emits radiant heat is constituted by a plurality of heat generating parts 36. More specifically, one heat generating portion 36 has an elongated shape. Thereby, the thermal resistance in the length direction of the heat generating portion 36 is increased.

The low heat conduction part 37 is arrange | positioned between the two heat generating parts 36 adjacent. Thereby, the thermal resistance between the two adjacent heat generating parts 36 is increased. As a result, the thermal resistance in the surface direction of the heater body layer 22 is increased. That is, the heat transfer in the surface direction is suppressed as compared with the case where the heat generating portion is configured by one heat generating portion continuous in the surface direction.

For this reason, when the heater body layer 22 is touched to the finger 1 or the face 2 of the user 1 and heat is transferred from the touched portion to the user 1, heat from the periphery of the touched portion to the touched portion is heated. Movement is suppressed. The temperature of the touched part quickly decreases. Thereby, the thermal discomfort to the user 1 can be reduced.

Thus, in this embodiment, when the user 1 touches the heater body layer 22, the heater body layer 22 has such a characteristic that the temperature of the portion touched by the user 1 rapidly decreases. 22 is configured.

The plurality of heat generating portions 36 are disposed in a region of the heater main body layer 22 facing at least the region to be heated of the face 2. The heating target area of the face 2 is, for example, a forehead, a nose, a cheek, and a chin.

As shown in FIG. 7, the beauty device 10 includes a control device 40, a battery 42, and an operation unit 44.

The control device 40 controls the energization amounts of the plurality of heat generating portions 36 of the heater body layer 22 so that the heater body layer 22 reaches the target temperature. Thereby, the control device 40 controls the temperature of the heater body layer 22. In the present embodiment, the control device 40 uniformly controls the energization amounts of the plurality of heat generating portions 36 throughout the heater body layer 22. Thereby, the control device 40 uniformly controls the temperature of the heater main body layer 22 throughout the heater main body layer 22. The control device 40 is provided in the heater unit layer 18. The control device 40 includes a microcomputer including memories such as a CPU, a ROM, and a RAM and its peripheral circuits. The control device 40 performs various calculations and processes based on the control program stored in the memory. The memory is a non-transitional tangible recording medium. A non-transitional tangible recording medium is a non-transitory tangible storage medium (ie, non-transitory tangible storage media).

The battery 42 is a power supply device that supplies power to the heater body layer 22. As the battery 42, various batteries such as a primary battery and a secondary battery can be used. As shown in FIG. 3, the battery 42 is provided inside the headband 14.

The operation unit 44 is operated by the user 1. The operation unit 44 has a switch such as a power switch. The operation unit 44 outputs a signal corresponding to the operation of the user 1 to the control device 40. As shown in FIG. 3, the operation unit 44 is provided on the headband 14.

Next, a method for using the beauty device 10 of this embodiment will be described.

User 1 applies lotion to the skin of face 2. Lotion is a beauty liquid. Thereafter, as shown in FIG. 2, the user 1 wears the beauty device 10. That is, the user 1 makes the mask main body 12 face the face 2 so that the mask main body 12 covers the face 2.

Alternatively, the user 1 affixes a skin lotion pack P1 having no exothermic property and containing skin lotion to the skin of the face 2. The lotion pack P1 is a sheet-like mask containing lotion. A sheet-like mask is an object having a fixed shape made of paper or cloth. The sheet-like mask has voids formed therein. Lotion is present in this void. Thereafter, as shown in FIG. 8, the user 1 wears the beauty device 10.

The user 1 turns on the power switch of the operation unit 44 after wearing the beauty device 10. Note that the user 1 may turn on the power switch before the user 1 wears the beauty device 10.

Thereby, the heater body layer 22 generates heat by energization and releases radiant heat. The skin of the face 2 of the user 1 is heated by this radiant heat. That is, when the lotion pack P1 is not used, the skin of the face 2 is directly heated by this radiant heat. Since the skin of the face 2 is heated, the penetration of the lotion into the skin of the face 2 is improved. When the lotion pack P2 is used, the lotion pack P1 is heated by this radiant heat. The skin of the face 2 is heated by the warmed skin lotion pack P1.

Here, when the lotion pack P1 is used, radiant heat is blocked by the lotion pack P1. For this reason, when the temperature of the heater body layer 22 is the same when the lotion pack P1 is used and when it is not used, when the lotion pack P1 is used, compared to when the lotion pack P1 is not used, Skin temperature is lowered. Therefore, the skin cannot be heated to an appropriate temperature for the penetration of the skin lotion.

Therefore, in the present embodiment, as described below, the controller 40 controls the heater body layer 22 so that the temperature of the heater body layer 22 is different between when the lotion pack P1 is used and when it is not used. The temperature is controlled.

2 and 3, the beauty device 10 includes a temperature sensor 46. The temperature sensor 46 is provided in a region facing the forehead of the user 1 on the user-side surface 18 b of the heater unit layer 18. The temperature sensor 46 is supported by the sensor support 48. The temperature sensor 46 is fixed to the heater unit layer 18 via a sensor support portion 48. The sensor support 48 has a shape or structure that can be expanded and contracted. The sensor support unit 48 supports the temperature sensor 46 so as to come into contact with the skin of the user 1 when the beauty device 10 is worn.

The temperature sensor 46 detects the temperature of an object facing the heater unit layer 18 with the space 3 interposed therebetween. Specifically, as shown in FIG. 2, the temperature sensor 46 contacts the skin of the user 1 when the lotion pack P1 is not used. The temperature sensor 46 detects the temperature of the skin of the user 1. On the other hand, as shown in FIG. 8, when the lotion pack P1 is used, the temperature sensor 46 contacts the lotion pack P1. The temperature sensor 46 detects the temperature of the lotion pack P1.

As shown in FIG. 7, the temperature sensor 46 is electrically connected to the control device 40. For this reason, the control device 40 can acquire the detection value of the temperature sensor 46. The detection value of the temperature sensor 46 is a detection result of the temperature sensor 46.

The control device 40 controls the temperature of the heater body layer 22 according to the flowchart shown in FIG. Each step shown in FIG. 9 corresponds to a functional unit that realizes various functions. This control is executed when the power switch of the operation unit 44 is on. When the power switch is switched from OFF to ON, the control device 40 controls the energization amount of the heater body layer 22 so that the temperature of the heater body layer 22 becomes the first temperature.

In step S1, the control device 40 acquires the detection value of the temperature sensor 46. The detection value is an electrical signal corresponding to the temperature of the detection target. When a thermistor is used as the temperature sensor 46, the detected value is a voltage value corresponding to the resistance value of the thermistor. The acquired detection value is detected after a predetermined time has elapsed since the power switch was switched from OFF to ON.

Subsequently, in step S2, the control device 40 determines whether or not the lotion pack P1 is present on the skin based on the acquired detection value.

Here, as shown in FIG. 10, when the skin lotion pack P1 is present on the skin, the temperature detected after the lapse of the predetermined time t1 is determined after the passage of the predetermined time t1 when the skin lotion pack P1 is not present on the skin. Below the detected temperature. This is because the amount of the lotion contained in the lotion pack P1 is larger than the amount of the lotion present on the skin when there is no lotion pack P1. That is, when there is no lotion pack P1 on the skin, there is a lotion applied directly on the skin, or there is no lotion on the skin. The amount of water contained in the lotion pack P1 is greater than the amount of water contained in the skin. For this reason, when there is the lotion pack P1 on the skin, the lotion pack from the start of the warming of the face 2 by the beauty device 10 compared to the increase in the skin temperature when there is no lotion pack P1 on the skin The rise in temperature of P1 becomes slow. Thus, when the amount of the lotion on the skin is large, the temperature of the object facing the heater unit layer 18 across the space 3 is lower than when the amount of the lotion on the skin is small. Therefore, the temperature of the object facing the heater unit layer 18 across the space 3 is a physical quantity that correlates with the amount of cosmetic liquid on the skin. The temperature sensor 46 is a physical quantity sensor that detects this physical quantity.

Therefore, in this step S2, the acquired detection value is compared with a preset threshold value. The temperature and the detected value described above have a relationship that the detected value increases as the temperature increases. In this case, it is determined whether or not the detected value is lower than the threshold value. If the detected value is higher than the threshold value, NO is determined. In this case, the process proceeds to step S3. If the detected value is lower than the threshold value, YES is determined. In this case, the process proceeds to step S4. In the present embodiment, step S2 corresponds to a determination unit that determines the presence or absence of an object on the skin.

In step S3, the control device 40 sets the target temperature of the heater body layer 22 to the first temperature.

Subsequently, in step S5, the control device 40 controls the energization amount of the heater body layer 22 so that the temperature of the heater body layer 22 becomes the target temperature, that is, the first temperature. Thereby, the temperature of the heater body layer 22 becomes the first temperature.

In step S4, the control device 40 sets the target temperature of the heater body layer 22 to the second temperature. The second temperature is a temperature higher than the first temperature. Subsequently, in step S5, the control device 40 controls the energization amount of the heater main body layer 22 so that the temperature of the heater main body layer 22 becomes the target temperature, that is, the second temperature. Thereby, the temperature of the heater body layer 22 becomes the second temperature. In the present embodiment, steps S3, S4, and S5 correspond to a temperature control unit that controls the temperature of the heater layer.

As described above, in the present embodiment, the control device 40 determines the presence or absence of the lotion pack P1 on the skin in step S2. When it determines with there being no lotion pack, the control apparatus 40 makes temperature of the heater main body layer 22 1st temperature by step S3, S5. On the other hand, when it is determined that there is a lotion pack, the control device 40 sets the temperature of the heater body layer 22 to the second temperature in steps S4 and S5.

According to this, the temperature of the heater body layer 22 can be made higher when the lotion pack P1 is used than when the lotion pack P1 is not used. Thereby, when using the lotion pack P1, more radiant heat can be released from the heater body layer 22 than when the lotion pack P1 is not used. Therefore, even when the lotion pack P1 is used, the skin of the user 1 can be heated so that the skin of the user 1 becomes an appropriate temperature.

Thus, according to the present embodiment, the temperature of the heater body layer 22 can be automatically controlled so that the temperature of the heater body layer 22 becomes an appropriate temperature regardless of the operation of the user 1.

In the present embodiment, the temperature sensor 46 detects the temperature of the skin or the lotion pack P1. An appropriate use time of the beauty device 10 is determined for each temperature. Therefore, the control device 40 calculates an appropriate usage time of the beauty device 10 based on the detected temperature. Thereby, the calculated usage time can be notified to the user.

(Second Embodiment)
As shown in FIG. 11, this embodiment is different from the first embodiment in that a humidity sensor 50 is used instead of the temperature sensor 46. FIG. 11 corresponds to FIG. Other configurations of the beauty device 10 are the same as those in the first embodiment.

The humidity sensor 50 detects the humidity of the space 3. The humidity sensor 50 is supported by the sensor support 52 so as not to contact the skin of the face 2 of the user 1 or the lotion pack P1 when the beauty device 10 is worn. The humidity sensor 50 does not come into contact with the object facing the heater unit layer 18 with the space 3 in between, with and without the lotion pack P1 indicated by the two-dot chain line in FIG.

The humidity sensor 50 is electrically connected to the control device 40 similarly to the temperature sensor 46 of the first embodiment. For this reason, the control apparatus 40 can acquire the detection value of the humidity sensor 50. The detection value of the humidity sensor 50 is a detection result of the humidity sensor 50.

Also in the present embodiment, as in the first embodiment, the control device 40 controls the temperature of the heater body layer 22 according to the flowchart shown in FIG.

In step S1, the control device 40 acquires the detection value of the humidity sensor 50. This detection value is an electric signal according to the humidity of the space 3 to be detected, for example, a voltage value. The acquired detection value is detected after a predetermined time has elapsed since the power switch was switched from OFF to ON.

Here, as shown in FIG. 12, when the skin lotion pack P1 is on the skin, the humidity detected after the lapse of the predetermined time t1 is after the passage of the predetermined time t1 when the skin lotion pack P1 is not on the skin. It is higher than the detected humidity.

This is because the amount of the lotion contained in the lotion pack P1 is larger than the amount of the lotion present on the skin when there is no lotion pack P1. When there is no lotion pack P1 on the skin, there is a lotion applied directly on the skin or there is no lotion on the skin. For this reason, when the lotion pack P1 is on the skin, the humidity of the space is higher than when the lotion pack P1 is not on the skin. Thus, when the amount of the lotion on the skin is large, the humidity detected by the humidity sensor 50 is higher than when the amount of the lotion on the skin is small. Therefore, the humidity of the space 3 is a physical quantity that correlates with the amount of cosmetic liquid on the skin. The humidity sensor 50 is a physical quantity sensor that detects this physical quantity.

Therefore, in step S2, the acquired detection value is compared with a preset threshold value. The humidity and the detected value have a relationship that the detected value increases as the humidity increases. In this case, it is determined whether or not the detected value is higher than a threshold value. If the detected value is lower than the threshold value, NO is determined. In this case, the process proceeds to step S3. If the detected value is higher than the threshold value, YES is determined. In this case, the process proceeds to step S4.

Steps S3, S4, and S5 are the same as those in the first embodiment.

Also in the present embodiment, similarly to the first embodiment, the temperature of the heater body layer 22 can be automatically controlled so that the temperature of the heater body layer 22 becomes an appropriate temperature regardless of the operation of the user 1. .

(Third embodiment)
As shown in FIG. 13, this embodiment is different from the first embodiment in that a resistance detector 54 is used instead of the temperature sensor 46. Other configurations of the beauty device 10 are the same as those in the first embodiment.

The resistance detector 54 is a detection unit that detects an electrical resistance value of an object facing the heater unit layer 18 with the space 3 interposed therebetween.

As shown in FIG. 14, the resistance detector 54 has two

electrodes

55 and 56. The two

electrodes

55 and 56 come into contact with the skin of the face 2 of the user 1 or the lotion pack P1 when the beauty device 10 is worn. The resistance detector 54 detects the electrical resistance value of the object between the two

electrodes

55 and 56. As a method for detecting the electric resistance value, a general contact-type electric resistance value detecting method can be employed.

As shown in FIG. 14, the two

electrodes

55 and 56 of the resistance detector 54 are in contact with the skin of the face 2 of the user 1 when the beauty device 10 is worn and the lotion pack is not used. Thereby, the resistance detector 54 detects the electrical resistance value of the skin of the user 1.

On the other hand, as shown in FIG. 15, when the cosmetic device 10 is mounted and the lotion pack P1 is used, the two

electrodes

55 and 56 of the resistance detector 54 are in contact with the lotion pack P1. Thereby, the resistance detector 54 detects the electrical resistance value of the lotion pack P1.

The resistance detector 54 is electrically connected to the control device 40 in the same manner as the temperature sensor 46 of the first embodiment. For this reason, the control apparatus 40 can acquire the detection value of the resistance detector 54. The detection value of the resistance detector 54 is a detection result of the resistance detector 54.

In step S1, the control device 40 acquires the detection value of the resistance detector 54. The detected value is an electric signal corresponding to the electric resistance value to be measured. The acquired detection value may be either one detected immediately after wearing the beauty device 10 or one detected after a predetermined time has elapsed since the power switch was switched from off to on.

Here, as shown in FIG. 16, the electrical resistance value detected when the lotion pack P1 is on the skin is lower than the electrical resistance value detected when the lotion pack P1 is not on the skin.

This is because the amount of the lotion contained in the lotion pack P1 is larger than the amount of the lotion present on the skin when there is no lotion pack P1. When there is no lotion pack P1 on the skin, there is a lotion applied directly on the skin or there is no lotion on the skin. Further, the amount of water contained in the lotion pack P1 is greater than the amount of water contained in the skin. For this reason, compared with the electrical resistance value of the skin when there is no lotion pack P1 on the skin, the electrical resistance value of the lotion pack P1 is low.

Thus, when the amount of skin lotion on the skin is large, the electrical resistance value of the object facing the heater unit layer 18 across the space 3 is lower than when the amount of skin lotion on the skin is small. Become. Therefore, the electrical resistance value of the object facing the heater unit layer 18 across the space 3 is a physical quantity that correlates with the amount of cosmetic liquid on the skin. The resistance detector 54 is a physical quantity sensor that detects this physical quantity.

Therefore, for example, a constant current flows through the object between the two

electrodes

55 and 56. At this time, the potential difference between the two

electrodes

55 and 56 is measured. This potential difference is used as a detection value. In this case, the potential difference when the lotion pack P1 is on the skin is smaller than the potential difference when the lotion pack P1 is not on the skin. Therefore, in step S2, the acquired detection value is compared with a preset threshold value. It is determined whether or not the detected value is smaller than a threshold value. If the detected value is greater than the threshold value, NO is determined. In this case, the process proceeds to step S3. If the detected value is smaller than the threshold value, YES is determined. In this case, the process proceeds to step S4.

Also, for example, a constant current is passed through the object between the two

electrodes

55 and 56. At this time, one of the two

electrodes

55 and 56 is connected to a power source. The other of the two

electrodes

55 and 56 is connected to the ground. Then, the potential of the electrode connected to the ground side of the two

electrodes

55 and 56 is measured. This potential is used as a detection value. In this case, the potential when the lotion pack P1 is on the skin is larger than the potential when the lotion pack P1 is not on the skin. Therefore, in step S2, the acquired detection value is compared with a preset threshold value. It is determined whether or not the detected value is greater than a threshold value. If the detected value is smaller than the threshold value, NO is determined. In this case, the process proceeds to step S3. If the detected value is greater than the threshold value, a YES determination is made. In this case, the process proceeds to step S4.

Steps S3, S4, and S5 are the same as those in the first embodiment.

In this embodiment, the resistance detector 54 detects the electrical resistance value of the skin or the lotion pack P1.

When using the lotion pack P1, the amount of water contained in the lotion pack P1 decreases as the heating time advances. When the amount of water decreases, the electrical resistance value of the lotion pack P1 increases. Therefore, the resistance detector 54 detects the electrical resistance value of the lotion pack P1 during heating. The control device 40 determines the heating end time from the detected value based on the change in the electrical resistance value with the passage of time of the lotion pack P1. Thereby, a user can be notified of a heating end time.
