Patent document 1: japanese patent No. 6282271

However, in the beauty device as described above, there is a demand for adding a function of heating the contact portion in order to provide comfort to the user. In this case, it is desirable to reduce energy consumption.

Disclosure of Invention

The present invention has been made in view of the above circumstances, and an object thereof is to provide a beauty device having a function of heating a contact portion and capable of reducing energy consumption.

Means for solving the problems

The beauty device of the present invention is a beauty device for use by being held, and includes: an abutting portion that contacts the skin; a detection unit that detects a state in which the beauty device is in contact with a user; and a control unit that, based on a detection result of the detection unit, sets the contact portion to a first target temperature in a state where the cosmetic device is not in contact with the user, and sets the contact portion to a second target temperature higher than the first target temperature in a state where the cosmetic device is in contact with the user.

The state where the cosmetic device is not in contact with the user and the state where the cosmetic device is in contact with the user include the following modes. That is, the mode includes a state in which the beauty device is not in contact with the user and is not held, and a state in which the beauty device is in contact with the user and is held but the contact portion is not in contact with the skin. The mode includes a state in which the beauty device is not in contact with the user, a state in which the beauty device is not gripped, and a state in which the abutting portion does not abut against the skin although the beauty device is gripped, and a state in which the beauty device is in contact with the user, and the abutting portion abuts against the skin.

Effects of the invention

According to the present invention, the contact portion is set to the first target temperature in a state where the cosmetic device is not in contact with the user, and is set to the second target temperature higher than the first target temperature in a state where the cosmetic device is in contact with the user. Therefore, energy consumption can be reduced as compared with a case where the contact portion continuously maintains the second target temperature from a state where the cosmetic device is not in contact with the user to a state where the cosmetic device is in contact with the user. In addition, since the temperature of the contact portion is changed in a series of operations before the cosmetic device starts to be used, the user can smoothly start using the cosmetic device.

In addition, when the contact portion is heated to the first target temperature in a state where the beauty appliance is not in contact with the user, the feeling of coolness when the beauty appliance is used can be alleviated.

In addition, by setting the second target temperature to the optimum temperature for the operation and setting the first target temperature to a temperature close to the second target temperature, the waiting time until the second target temperature is reached can be shortened, and the stress of the user can be reduced.

Further, when the abutting portion is brought into contact with the skin at the start of use of the beauty apparatus, if the difference between the skin temperature of the user and the temperature of the abutting portion is large, the user may feel uncomfortable. However, by setting the first target temperature to a temperature closer to the second target temperature than the skin temperature of the user, the difference between the skin temperature of the user and the temperature of the contact portion when the cosmetic device is started to be used can be reduced, and the user can feel less uncomfortable.

Detailed Description

Preferred embodiments of the present invention are described below.

The beauty device of the present invention may have a grip portion, and the detection portion may be provided in the grip portion. According to this configuration, the portion having the detection section and the grip section do not need to be provided separately, and therefore the cosmetic device can be downsized. In addition, in the case where the heated contact portion is provided with the detection portion, the detection portion may malfunction, but such malfunction can be made difficult to occur by providing the detection portion in the grip portion.

In the cosmetic device according to the present invention, a temperature gradient in which the contact portion rises from the first target temperature to the second target temperature may be smaller than a temperature gradient in which the contact portion rises to the first target temperature. According to such a configuration, the abutting portion is gradually raised to the second target temperature, and thus excessive heating (overshoot) of the abutting portion can be prevented. Such temperature control by the control unit is realized in a normal use environment.

In the beauty device according to the present invention, when the hand is in contact with the grip portion and the skin is in contact with the contact portion, a closed circuit can be formed through the human body, so that a weak current flows to the contact portion, the detection portion detects the energization of the closed circuit, and the control portion raises the contact portion to the second target temperature based on the energization of the closed circuit detected by the detection portion. According to such a configuration, when the contact portion comes into contact with the skin, the contact portion starts to rise to the second target temperature. Therefore, energy consumption can be further reduced as compared with a case where the contact portion starts to rise to the second target temperature from the time when the contact portion does not contact the skin while the cosmetic device is being held. In addition, the load on the skin can be reduced as compared with the case where the contact portion is increased from the first contact with the skin to the second target temperature.

< example 1>

Hereinafter, embodiment 1 embodying the present invention will be described in detail with reference to fig. 1 to 6.

The beauty device 10 of the present embodiment is a beauty device that is used by being held by a user's hand, and has a flat shape of a long and thin heart as a whole, as shown in fig. 1. The beauty device 10 has a wireless charging function, and is charged by a charger not shown.

The beauty device 10 includes a grip 11 gripped by a user and two contact portions (hereinafter referred to as a first contact portion 12 and a second contact portion 13) that contact the skin of the user. The beauty device 10 includes a detection unit 14 and a control unit 15, the detection unit 14 detects whether the beauty device 10 is in a state of not contacting with a user or the beauty device 10 is in a state of contacting with the user, and the control unit 15 controls the temperatures of the first contact portion 12 and the second contact portion 13 based on the detection result of the detection unit 14 (see fig. 3).

The cosmetic device 10 has three modes of use. When the switch unit 16 of the beauty device 10 is operated and the power is turned on, the first contact unit 12 and the second contact unit 13 are at least 30 degrees in any usage mode. The first mode is a mode in which a weak current is caused to flow to the first contact portion 12 to perform heating, the second mode is a mode in which a weak current is caused to flow to the second contact portion 13 to perform heating, and the third mode is a mode in which only a weak current is caused to flow to both the first contact portion 12 and the second contact portion 13, that is, a mode in which only the first contact portion 12 and the second contact portion 13 are heated. The temperature of the first abutment 12 in the first mode is higher than the temperature of the second abutment 13 in the second mode. The temperatures of the first contact portion 12 and the second contact portion 13 in the third mode are higher than the temperature of the second contact portion 13 in the second mode.

As shown in fig. 2, the grip portion 11 includes an inner housing 18 accommodating therein the circuit board 17 and the like, and an outer cover 19 covering an outer surface of the inner housing 18. The outer peripheral surface (right side surface in fig. 1) of the grip portion 11 is curved outward. This makes it easy for the outer peripheral surface of the grip 11 to be attached to the palm of the hand and gripped, thereby facilitating the operation. Further, since the user grips the grip portion 11 with the outer peripheral surface of the grip portion 11 oriented along the palm, the range of the outer surface of the grip portion 11 that the user's fingers contact can be estimated in advance, and the touch pad 37 described later can be disposed at an appropriate position.

The inner housing 18 includes a first housing 18F and a second housing 18S that are fitted to each other. The first casing 18F and the second casing 18S are fixed in a state of being fitted with a plurality of screws N10, and are sealed by a waterproof packing 57.

A battery E as a power source to be wirelessly charged is housed in the inner case 18. The battery E is a lithium ion rechargeable battery, and a terminal (not shown) of the battery E is electrically connected to the circuit board 17.

The switch unit 16, the circuit board 17, the receiving coil 50 for wireless charging, the first contact portion 12 and the second contact portion 13, and the plurality of light emitting

units

21, 22, 23, and 24 are fixed to the inner case 18.

The switch section 16 is fixed to the first housing 18F by a screw N12. The switch unit 16 switches the power supply on, off, and use modes by a pressing operation. The switch unit 16 is electrically connected to a circuit board 17 on which a microcomputer or the like constituting the control unit 15 and the detection unit 14 is mounted.

The circuit board 17 is fixed to the first case 18F by a screw N11. The reception coil 50 is attached to the first case 18F, covered with the cover 19, and sealed with the sealing member 52. The first housing 18F is provided with a control device 53 for controlling wireless charging of the cosmetic device 10.

The first contact portion 12 and the second contact portion 13 are fixed to the first housing 18F by screws N14. The first contact portion 12 and the second contact portion 13 are both made of metal or resin and have a conductive plating film formed on the entire surface thereof. The plating film of the first contact portion 12 and the plating film of the second contact portion 13 are electrically connected to the circuit board 17 via screws N14.

The first abutting portion 12 and the second abutting portion 13 are different in curved shape.

As shown in fig. 1, the first abutting portion 12 has a shape in which two curved protrusions are aligned. The two protrusions are curved with different curvatures, and a concave shape is formed between the two protrusions.

The second contact portion 13 is formed in an arcuate shape in which a middle portion in the vertical direction in fig. 1 is recessed to the right side. The second abutting portion 13 is gently curved so as to follow the curve of the cheek of the person with a smaller curvature than the protruding portion of the first abutting portion 12.

By making the curved shapes of the first contact portion 12 and the second contact portion 13 different, a contact portion having a shape that can be easily bonded to either one of the first contact portion 12 and the second contact portion 13 can be selected to perform a surgical operation in accordance with the shape of the surface to be treated, and the surgical effect can be improved. Further, since the first contact portion 12 and the second contact portion 13 can be easily distinguished according to the shape, the use mode can be easily determined according to which of the first contact portion 12 and the second contact portion 13 is in contact with the skin.

A first heat generating body 31 that heats the first contact portion 12, a first temperature sensor 32 that measures the temperature of the first contact portion 12, and a first vibration motor 33 that vibrates the first contact portion 12 are provided between the first contact portion 12 and the inner housing 18.

As shown in fig. 2, the portion of the inner housing 18 covered by the first abutting portion 12 is bent along the shape of the inner surface of the first abutting portion 12. This allows the first heat generating element 31 to be disposed in close proximity to or in contact with the inner surface of the first contact portion 12, thereby rapidly heating the first contact portion 12.

A second heating element 34 that heats the second contact portion 13, a second temperature sensor 35 that measures the temperature of the second contact portion 13, and a second vibration motor 36 that vibrates the second contact portion 13 are provided between the second contact portion 13 and the inner case 18.

As shown in fig. 2, the portion of the inner case 18 covered by the second abutting portion 13 is bent along the shape of the inner surface of the second abutting portion 13. This allows the second heating element 34 to be disposed in close proximity to or in contact with the inner surface of the second contact portion 13, thereby quickly heating the second contact portion 13.

The first heating element 31 and the second heating element 34 are both planar thin film heaters with heat retaining sheets. The first heating element 31 and the second heating element 34 are both waterproof by a gasket not shown.

The first temperature sensor 32 and the second temperature sensor 35 are, for example, thermistors, and are disposed in contact with or in close proximity to the first contact portion 12 or the second contact portion 13, respectively. Both the first temperature sensor 32 and the second temperature sensor 35 are waterproof by the gasket 61.

As shown in fig. 1, the plurality of light-emitting

portions

21, 22, 23, and 24 include a first light-emitting portion 21 arranged at a position separating the first contact portion 12 and the second contact portion 13, and three light-emitting portions (hereinafter referred to as a second light-emitting portion 22, a third light-emitting portion 23, and a fourth light-emitting portion 24) that light up on the front side of the outer cover 19. The first light emitting unit 21, the second light emitting unit 22, the third light emitting unit 23, and the fourth light emitting unit 24 are formed of Light Emitting Diodes (LEDs), and are electrically connected to the circuit board 17. Holder 55 holding second light emitting unit 22, third light emitting unit 23, and fourth light emitting unit 24 is fixed to second case 18S by screws N13.

The first light emitting unit 21 emits light in different modes (blinking, lighting, and different colors) to indicate the state of the beauty appliance 10 such as which usage mode the beauty appliance 10 is in. The second light emitting unit 22 is kept lit when the cosmetic device 10 is in the first mode, the third light emitting unit 23 is kept lit when the cosmetic device 10 is in the second mode, and the fourth light emitting unit 24 is kept lit when the cosmetic device 10 is in the third mode. When the power of the beauty device 10 is turned off, all of the first light-emitting unit 21, the second light-emitting unit 22, the third light-emitting unit 23, and the fourth light-emitting unit 24 are turned off.

As shown in fig. 2, the cover 19 includes a first cover 19F covering the first case 18F and a second cover 19S covering the second case 18S. The first cover 19F and the second cover 19S are held in a fitted state by locking

portions

58 and 59 provided at the outer peripheral edge portion.

A fitting hole 62 into which the touch pad 37 is fitted is formed through the second cover 19S. The touch panel 37 is made of metal or resin, and has a conductive plating film formed on the entire surface. In a state where the touch pad 37 is fitted into the fitting hole 62, a connector portion, not shown, on the back surface of the touch pad 37 is in a state of being in contact with the terminal 54. The terminal 54 is attached to the second housing 18S and electrically connected to the circuit board 17.

When the hand is in contact with the grip 11 and the skin is in contact with the first contact portion 12 or the second contact portion 13, the beauty device 10 can form a closed circuit through the human body, and a weak current can flow to the first contact portion 12 or the second contact portion 13. Specifically, in a state where the use mode of the beauty device 10 is selected as the first mode, in a state where a part of the human body such as a hand or a finger is in contact with the touch pad 37 of the grip portion 11 and another part of the human body such as a cheek is in contact with the first contact portion 12, a potential difference is generated between the touch pad 37 and the first contact portion 12, and a weak current flows between the first contact portion 12 and the touch panel. In a state where the use mode of the beauty device 10 is selected to be the second mode, in a state where a part of the human body such as a hand or a finger is in contact with the touch panel 37 of the grip portion 11 and another part of the human body such as a cheek is in contact with the second contact portion 13, a potential difference is generated between the touch panel 37 and the second contact portion 13, and a weak current flows between the second contact portion 13 and the touch panel.

When the hand is separated from the grip 11 or the skin is separated from the first contact portion 12 or the second contact portion 13, the weak current flowing to the first contact portion 12 or the second contact portion 13 is stopped.

As shown in fig. 3, the battery E, the switch unit 16, the first light-emitting unit 21, the second light-emitting unit 22, the third light-emitting unit 23, the fourth light-emitting unit 24, the detection unit 14, the touch panel 37, the first contact unit 12, the first heat-generating body 31, the first temperature sensor 32, the first vibration motor 33, the second contact unit 13, the second heat-generating body 34, the second temperature sensor 35, and the second vibration motor 36 are connected to the control unit 15.

When the power of the beauty device 10 is turned on, the control unit 15 supplies a pulse current to between the touch panel 37 and the first contact portion 12 and between the touch panel 37 and the second contact portion 13 for human body detection. The detection pulse current is not continuous but supplied at regular time intervals.

When the touch panel 37 and the first contact portion 12 are connected to each other via a human body and a current flows, the detection portion 14 detects this, and when the touch panel 37 and the second contact portion 13 are connected to each other via a human body and a current flows, the detection portion 14 detects this. Thus, the detection unit 14 detects whether the beauty device 10 is in a state of not contacting the user or in a state of contacting the user. That is, in the present embodiment, a state in which the beauty device 10 is not gripped and a state in which the first contact portion 12 and the second contact portion 13 do not contact the skin while the beauty device 10 is gripped are states in which the beauty device 10 does not contact the user. The state in which the beauty device 10 is held and the first contact portion 12 or the second contact portion 13 is in contact with the skin is a state in which the beauty device 10 is in contact with the user.

The control unit 15 controls the first heat generator 31 to be turned on and off so that the temperature of the first contact portion 12 becomes a predetermined temperature, based on the detection result of the detection unit 14, the selected usage mode, and the input signal from the first temperature sensor 32. The control unit 15 controls the second heating element 34 to be turned on and off so that the temperature of the second contact portion 13 becomes a predetermined temperature, based on the detection result of the detection unit 14, the selected usage mode, and the input signal from the second temperature sensor 35.

The controller 15 controls the first heat generator 31 and the second heat generator 34 in the first mode and the third mode as follows. In a state where the beauty device 10 is not in contact with the user, the first heating element 31 and the second heating element 34 are controlled so that the first contact portion 12 or the second contact portion 13 is raised to the first target temperature. When the beauty device 10 is in contact with the user, the first heating element 31 and the second heating element 34 are controlled so that the first contact portion 12 or the second contact portion 13 is raised to a second target temperature higher than the first target temperature. At this time, the control unit 15 controls the temperature gradient of the first contact portion 12 or the second contact portion 13 from the first target temperature to the second target temperature to be smaller than the temperature gradient of the first contact portion 12 or the second contact portion 13 from the normal temperature to the first target temperature.

The control unit 15 controls the second heating element 34 in the second mode so that the temperature of the second contact portion 13 becomes constant.

The control unit 15 causes a current of substantially one polarity (hereinafter referred to as a first current) to flow to the first contact portion 12 in the first mode, and causes a current of an alternate polarity (hereinafter referred to as a second current) to flow to the second contact portion 13 in the second mode.

The control unit 15 drives the first vibration motor 33 in the first mode and drives the second vibration motor 36 in the second mode. The control unit 15 has a timer function (timer function).

Next, an example of the operation of the beauty device 10 of the present embodiment will be described.

First, an example of the operation of the cosmetic device 10 in the first mode will be described with reference to the flowchart of fig. 4.

When the user operates the switch unit 16 to turn on the power supply (S100), the control unit 15 starts to measure the time elapsed from the power supply of the beauty appliance 10. Then, when the user selects the first mode (S101), the control unit 15 heats the first heat generating body 31 to raise the temperature of the first contact portion 12 to the first target temperature (38 degrees in the present embodiment) (S102). At this time, the control unit 15 rapidly heats the first heat generator 31 so that the first contact portion 12 reaches the first target temperature in about 1 minute, assuming that the temperature of the first contact portion 12 before the power is turned on is 15 degrees. Although not shown in the flow chart, the control unit 15 heats the second heating element 34 to raise the second contact portion 13 to a standby temperature (30 degrees in the present embodiment) lower than the first target temperature. During this period, the controller 15 gradually causes the first light-emitting unit 21 to blink in white, turns on the second light-emitting unit 22, and maintains the third light-emitting unit 23 and the fourth light-emitting unit 24 in an off state.

When the first contact portion 12 reaches the first target temperature, the control portion 15 maintains the first contact portion 12 at the first target temperature (S103), and the beauty appliance 10 is placed in a standby state. When the first contact portion 12 becomes equal to or higher than the first target temperature, the control portion 15 stops heating, and when the first contact portion becomes equal to or lower than the first target temperature, the control portion performs heating to maintain the first contact portion 12 at the first target temperature. The controller 15 keeps the first light-emitting unit 21 blinking slowly in white, lights the second light-emitting unit 22, and keeps the third light-emitting unit 23 and the fourth light-emitting unit 24 off.

When the time elapsed from the power-on of the beauty device 10 exceeds a predetermined time (5 minutes in the present embodiment) (yes in S104), the control unit 15 automatically turns off the power (S108). The controller 15 turns off all the

light emitting units

21, 22, 23, and 24, and stops heating of the first and

second heat generators

31 and 34. This prevents the beauty device 10 from being left for a predetermined time or longer in the powered-on state, and thus prevents wasteful energy consumption.

When the user does not start using the beauty appliance 10, that is, does not grip the beauty appliance 10 in the standby state, but keeps the beauty appliance 10 in the standing state, or holds the beauty appliance 10 in the standby state, but keeps the first contact portion 12 in a state of not contacting the skin and does not perform skin detection (no in S105), the control portion 15 maintains the temperature of the first contact portion 12 at the first target temperature.

When the user holds the beauty appliance 10 in the standby state and brings the first contact portion 12 into contact with the skin during a period in which the predetermined time has not elapsed from the power-on of the beauty appliance 10 (no in S104), the current flows to the first contact portion 12 and the detection portion 14 detects this (yes in S105), and the control portion 15 starts the operation in the first mode (S106). Here, when the user brings the first contact portion 12 into contact with the skin, the first contact portion 12 reaches the first target temperature. Since the first target temperature in the present embodiment is 38 degrees which is the same as the body temperature of a human, the sensation of coolness when the first contact portion 12 is brought into contact with the skin can be eliminated. The control unit 15 resets a timer started when the power of the beauty device 10 is turned on, and starts measuring the time elapsed since the first contact portion 12 comes into contact with the skin instead.

When the operation in the first mode is started, the control unit 15 heats the first heat generator 31 to raise the temperature of the first contact portion 12 to the second target temperature (41 degrees in the present embodiment). At this time, the control unit 15 raises the temperature of the first contact portion 12 from the first target temperature to the second target temperature at a speed slower than the speed at which the first contact portion 12 is raised to the first target temperature. This can reduce the pressure applied to the skin of the user. Further, if the temperature is rapidly increased, so-called overshoot may occur in which the first heat generator 31 excessively increases, and as a result, such an excessive increase in temperature can be prevented. The control unit 15 causes the first current to flow to the first contact portion 12, and drives the first vibration motor 33. The user senses that the first mode is operating by the vibration of the first vibration motor 33. The controller 15 keeps the second contact portion 13 at the standby temperature, and then gradually blinks the first light-emitting portion 21 in white to turn on the second light-emitting portion 22, and maintains the third light-emitting portion 23 and the fourth light-emitting portion 24 in a turned-off state.

When the time elapsed since the first contact portion 12 was in contact with the skin exceeds a predetermined time (5 minutes in the present embodiment) (yes in S107), the control portion 15 automatically turns off the power supply (S108). The controller 15 turns off all the

light emitting units

21, 22, 23, and 24, and stops heating of the first and

second heat generators

31 and 34. The control unit 15 maintains the operation in the first mode for a period in which the time elapsed after the first contact portion 12 comes into contact with the skin does not elapse the predetermined time (S107: no).

Next, an example of the operation of the cosmetic device 10 in the second mode will be described with reference to the flowchart of fig. 5.

When the user operates the switch unit 16 to turn on the power supply (S200), the control unit 15 starts to measure the time elapsed from the power supply of the beauty appliance 10. When the user selects the second mode (S201), the control unit 15 heats the second heating element 34 to raise the temperature of the second contact portion 13 to a predetermined operation temperature (30 degrees in the present embodiment) (S202). The operating temperature in the second mode (the mode in which the second current is caused to flow to the second contact portion 13) is set to a temperature slightly lower than the operating temperature (41 degrees) suitable for the first mode (the mode in which the first current is caused to flow to the first contact portion 12). Although not shown in the flowchart, the control unit 15 heats the first heat generator 31 to raise the first contact portion 12 to the standby temperature (30 degrees). The standby temperature of the first contact portion 12 is the same as the standby temperature of the second contact portion 13 in the first mode. During this time, the controller 15 gradually blinks the first light-emitting unit 21 in blue, lights up the third light-emitting unit 23, and turns off the second light-emitting unit 22 and the fourth light-emitting unit 24.

When the second contact portion 13 is heated to the predetermined treatment temperature, the control portion 15 maintains the second contact portion 13 at the predetermined treatment temperature (S203), and the cosmetic device 10 is in the standby state. When the second contact portion 13 reaches the predetermined operation temperature or higher, the control portion 15 stops heating, and when the second contact portion reaches the predetermined operation temperature or lower, the control portion heats the second contact portion 13 to maintain the operation temperature. The controller 15 keeps the first light-emitting unit 21 blinking slowly in blue, lights up the third light-emitting unit 23, and keeps the second light-emitting unit 22 and the fourth light-emitting unit 24 off. When the time elapsed from the power-on of the beauty device 10 exceeds a predetermined time (5 minutes in the present embodiment) (yes in S204), the control unit 15 automatically turns off the power (S208). The controller 15 turns off all the

light emitting units

21, 22, 23, and 24, and stops heating of the first and

second heat generators

31 and 34. Accordingly, as in the first mode, the beauty device 10 can be prevented from being left for a predetermined time or more in the powered-on state, and wasteful energy consumption can be prevented.

When the user does not start using the beauty treatment apparatus 10, that is, does not grip the beauty treatment apparatus 10 in the standby state, and keeps the state in which the second contact portion 13 is not in contact with the skin, and does not perform skin detection, even if the user grips the beauty treatment apparatus 10 in the standby state (no in S205), the control portion 15 maintains the second contact portion 13 at the operation temperature.

When the user holds the beauty appliance 10 in the standby state and brings the second contact portion 13 into contact with the skin during a period in which the predetermined time has not elapsed from the power-on of the beauty appliance 10 (no in S204), a current flows to the second contact portion 13, the detection portion 14 detects this (yes in S205), and the control portion 15 starts the operation in the second mode (S206). The control unit 15 resets a timer started when the power of the beauty device 10 is turned on, and starts measuring the time elapsed after the second contact portion 13 comes into contact with the skin instead. The control unit 15 causes a second current to flow to the second contact portion 13 while maintaining the temperature of the second contact portion 13 at a predetermined operation temperature, and drives the second vibration motor 36. The user senses that the second mode is operating by the vibration of the second vibration motor 36. During this time, the controller 15 keeps the temperature of the first contact portion 12 at the standby temperature, turns on the first light-emitting portion 21 in blue, turns on the third light-emitting portion 23, and maintains the second light-emitting portion 22 and the fourth light-emitting portion 24 in an off state.

When the time elapsed since the second contact portion 13 was in contact with the skin exceeds a predetermined time (5 minutes in the present embodiment) (yes in S207), the control portion 15 automatically turns off the power supply (S208). Further, the controller 15 turns off all the

light emitting units

21, 22, 23, and 24, and stops the heating of the first and

second heating elements

31 and 34. The control unit 15 maintains the operation in the second mode for a period in which the time elapsed after the second contact portion 13 comes into contact with the skin does not elapse the predetermined time (S207: no).

Next, an example of the operation of the beauty device 10 in the third mode will be described with reference to the flowchart of fig. 6.

When the user operates the switch unit 16 to turn on the power supply (S300), the control unit 15 starts to measure the time elapsed from the power supply of the beauty appliance 10. When the user selects the third mode (S301), the control unit 15 heats the first and

second heating elements

31 and 34 to raise the temperature of the first and

second contact portions

12 and 13 to the first target temperature (38 degrees) (S302). During this period, the controller 15 gradually blinks the first light-emitting unit 21 in red, lights up the fourth light-emitting unit 24, and turns off the first light-emitting unit 21 and the second light-emitting unit 22.

When the first contact portion 12 and the second contact portion 13 reach the first target temperature, the control portion 15 maintains the first contact portion 12 and the second contact portion 13 at the first target temperature (S303), and the beauty appliance 10 is in a standby state. When the first contact portion 12 and the second contact portion 13 reach the first target temperature or higher, the control portion 15 stops heating, and when the first contact portion 12 and the second contact portion 13 reach the first target temperature or lower, the control portion heats the contact portions to maintain the first contact portion 12 and the second contact portion 13 at the first target temperature. The controller 15 turns on the first light-emitting unit 21 in red, turns on the fourth light-emitting unit 24, and turns off the second light-emitting unit 22 and the third light-emitting unit 23. When the time elapsed from the power-on of the beauty device 10 exceeds a predetermined time (5 minutes in the present embodiment) (yes in S304), the control unit 15 automatically turns off the power (S310). The controller 15 turns off all the

light emitting units

21, 22, 23, and 24, and stops heating of the first and

second heat generators

31 and 34. Accordingly, similarly to the first mode and the second mode, the cosmetic device 10 can be prevented from being left for a predetermined time or longer in a power-on state, and wasteful energy consumption can be prevented.

When the user does not start using the beauty appliance 10, that is, does not grip the beauty appliance 10 in the standby state, but keeps the beauty appliance 10 in the standing state, or holds the beauty appliance 10 in the standby state, but keeps the first contact portion 12 or the second contact portion 13 in a state of not contacting the skin and does not perform skin detection (yes in S305), the control portion 15 maintains the first contact portion 12 and the second contact portion 13 at the first target temperature.

When a predetermined time has not elapsed since the beauty appliance 10 is powered on (no in S304), if the user holds the beauty appliance 10 in the standby state and brings the first contact portion 12 or the second contact portion 13 into contact with the skin, the detection signal flows to the first contact portion 12 when the first contact portion 12 is in contact with the skin, and the detection unit 14 detects this (yes in S305 and yes in S306), and the control unit 15 starts the operation of the first thermal mode (S307). The control unit 15 resets a timer started when the power of the beauty device 10 is turned on, and starts measuring the time elapsed since the first contact portion 12 comes into contact with the skin instead. The control unit 15 raises the temperature of the first contact portion 12 to a second target temperature (41 degrees), and maintains the second contact portion 13 at the first target temperature. The controller 15 keeps the first light-emitting unit 21 lit in red, the fourth light-emitting unit 24 lit, and the second light-emitting unit 22 and the third light-emitting unit 23 off.

When the user brings the second contact portion 13 into contact with the skin, a current flows to the second contact portion 13, the detection portion 14 detects this (yes in S305 and no in S306), and the control portion 15 starts the operation of the second thermal mode (S308). The control unit 15 resets a timer started when the power of the beauty device 10 is turned on, and starts measuring the time elapsed after the second contact portion 13 comes into contact with the skin instead. The control unit 15 sets the second contact portion 13 to the second target temperature (41 degrees) and maintains the first contact portion 12 at the first target temperature. The controller 15 keeps the first light-emitting unit 21 lit in red, the fourth light-emitting unit 24 lit, and the second light-emitting unit 22 and the third light-emitting unit 23 off.

When the time elapsed since the first contact portion 12 or the second contact portion 13 was in contact with the skin exceeds a predetermined time (5 minutes in the present embodiment) (yes in S309), the control portion 15 automatically turns off the power supply (S310). The controller 15 turns off all the

light emitting units

21, 22, 23, and 24, and stops the heating of the first and

second heating elements

31 and 34. The control unit 15 maintains the operation in the third mode until the time elapsed since the first contact portion 12 or the second contact portion 13 contacted the skin does not elapse the predetermined time (S309: no).

Further, the beauty device 10 of the present embodiment can be changed to another use mode in the middle of the use mode.

For example, when the switch unit 16 of the cosmetic container 10 is operated in the standby state of the first mode and switched to the second mode, the user can start using the cosmetic container without waiting for the second contact portion 13 to be heated. This is because the second contact portion 13 has a standby temperature (30 degrees) in the standby state of the first mode, which is the same temperature as the operating temperature of the second mode.

For example, when the switch unit 16 of the cosmetic container 10 is operated in the standby state of the third mode and switched to the second mode, the second contact portion 13 reaches the first target temperature (38 degrees) in the standby state of the third mode. The first target temperature is lower than the second target temperature (41 degrees) and is a temperature close to the second mode operating temperature (30 degrees). Therefore, the temperature can be reduced to the operating temperature in the second mode in a shorter time than when the second abutting portion 13 is reduced from the second target temperature to the operating temperature in the second mode.

When the usage mode is changed to another usage mode in the middle of the usage mode, the control unit 15 resets the timer while selecting another usage mode, and starts measuring the elapsed time from when the other mode is selected instead.

Next, the operation and effect of the embodiment configured as described above will be described.

The beauty device 10 of the present embodiment is a beauty device 10 that is used while being held, and includes: a first abutting portion 12 and a second abutting portion 13, the first abutting portion 12 and the second abutting portion 13 being in contact with the skin; a detection unit 14, wherein the detection unit 14 detects whether the beauty device 10 is in a state of not contacting with the user or in a state of contacting with the user; and a control unit 15, wherein the control unit 15 sets the first contact portion 12 or the second contact portion 13 to a first target temperature in a state where the beauty device 10 is not in contact with the user, and sets the first contact portion 12 or the second contact portion 13 to a second target temperature higher than the first target temperature in a state where the beauty device 10 is in contact with the user. According to this configuration, the first contact portion 12 or the second contact portion 13 is set to the first target temperature in a state where the cosmetic device 10 is not in contact with the user, and is set to the second target temperature higher than the first target temperature in a state where the cosmetic device 10 is in contact with the user. Therefore, energy consumption can be reduced as compared with a case where the first contact portion 12 or the second contact portion 13 continuously maintains the second target temperature from the state of not being in contact with the beauty device 10 to the state of being in contact with it. Further, since the temperature change of the first contact portion 12 or the second contact portion 13 is performed in a series of operations before the cosmetic device 10 starts to be used, the user can smoothly start using the cosmetic device 10.

Further, since the first contact portion 12 and the second contact portion 13 are heated to the first target temperature in a state where the beauty appliance 10 is not in contact with the user, the feeling of coolness when the beauty appliance 10 is used can be alleviated.

Further, when the first contact portion 12 or the second contact portion 13 is brought into contact with the skin when the beauty device 10 is started to be used, the user may feel uncomfortable when the difference between the skin temperature of the user and the temperature of the contact portion is large. However, by setting the first target temperature to a temperature closer to the second target temperature than the skin temperature of the user, the difference between the skin temperature of the user when the cosmetic device 10 starts to be used and the temperature of the first contact portion 12 or the second contact portion 13 can be reduced, and the user can feel less uncomfortable.

The beauty device 10 of the present embodiment includes a grip 11, and the detection unit 14 is provided in the grip 11. According to this configuration, since the portion having the detection unit 14 does not need to be provided separately from the grip 11, the cosmetic device 10 can be downsized. In addition, in the case where the detection unit 14 is provided in the heated first contact portion 12 or second contact portion 13, although there is a possibility that the detection unit 14 may malfunction, such malfunction can be made less likely to occur by providing the detection unit 14 in the grip portion 11.

In the beauty device 10 of the present embodiment, the temperature gradient at which the first contact portion 12 or the second contact portion 13 rises from the first target temperature to the second target temperature is smaller than the temperature gradient at which the first contact portion 12 or the second contact portion 13 rises to the first target temperature. According to this configuration, since the first contact portion 12 or the second contact portion 13 is gradually increased to the second target temperature, excessive heating (overshoot) of the first contact portion 12 or the second contact portion 13 can be prevented.

In the beauty device 10 of the present embodiment, when the hand is in contact with the grip portion 11 and the skin is in contact with the first contact portion 12 or the second contact portion 13, a closed circuit is formed via the human body, so that a weak current flows to the first contact portion 12 or the second contact portion 13, the detection portion 14 detects the energization of the closed circuit, and the control portion 15 raises the first contact portion 12 or the second contact portion 13 to the second target temperature based on the energization of the closed circuit detected by the detection portion 14. According to this configuration, when the first contact portion 12 or the second contact portion 13 comes into contact with the skin, the first contact portion 12 or the second contact portion 13 starts to rise to the second target temperature. Therefore, energy consumption can be further reduced as compared with a case where the first contact portion 12 or the second contact portion 13 starts to rise to the second target temperature when the first contact portion 12 or the second contact portion 13 does not contact the skin while the beauty device 10 is being held. Further, the load on the skin can be reduced as compared with the case where the first contact portion 12 or the second contact portion 13 is increased from the first contact with the skin to the second target temperature.

< example 2>

Next, a cosmetic device according to example 2 embodying the present invention will be described with reference to fig. 7 to 9.

The beauty device of the present embodiment is different from embodiment 1 in the timing at which the control unit starts measuring the elapsed time. Note that the same components as those in embodiment 1 are denoted by the same reference numerals, and redundant description thereof is omitted.

The beauty device 10 of the present embodiment includes a grip 11, a first contact portion 12, and a second contact portion 13, a detection portion 14 for detecting whether the beauty device 10 is in a state of not contacting the user or in a state of contacting the user, and a control portion 15 for controlling the temperatures of the first contact portion 12 and the second contact portion 13 based on the detection result of the detection portion 14, as in embodiment 1. The beauty device 10 has three modes of use as in embodiment 1.

First, an example of the operation of the cosmetic device 10 in the first mode will be described with reference to the flowchart of fig. 7.

When the user operates the switch unit 16 to turn on the power supply (S400) and selects the first mode (S401), the control unit 15 heats the first heat generator 31 to raise the temperature of the first contact portion 12 to the first target temperature (38 degrees in the present embodiment) (S402). Although not shown in the flow chart, the control unit 15 heats the second heating element 34 to raise the second contact portion 13 to a standby temperature (30 degrees in the present embodiment) lower than the first target temperature.

When the first contact portion 12 reaches the first target temperature, the control portion 15 maintains the first contact portion 12 at the first target temperature (S403), and the beauty appliance 10 is placed in a standby state. Further, the control unit 15 starts measuring the time elapsed from when the beauty appliance 10 is placed in the standby state.

When the user holds the beauty device 10 in the standby state and brings the first contact portion 12 into contact with the skin, a current flows to the first contact portion 12, the detection portion 14 detects this (yes in S404), and the control portion 15 starts the operation in the first mode (S405).

When the operation in the first mode is started, the control unit 15 heats the first heat generator 31 to raise the temperature of the first contact portion 12 to the second target temperature (41 degrees in the present embodiment). At this time, the control unit 15 raises the temperature of the first contact portion 12 from the first target temperature to the second target temperature at a speed slower than the speed at which the first contact portion 12 is raised to the first target temperature, as in embodiment 1. The control unit 15 causes the first current to flow to the first contact portion 12, and drives the first vibration motor 33.

When the user does not start using the beauty appliance 10, that is, does not grip the beauty appliance 10 in the standby state, but keeps the beauty appliance 10 in the standing state, or holds the beauty appliance 10 in the standby state, but keeps the first contact portion 12 in a state of not contacting the skin and does not perform skin detection (no in S404), the control portion 15 maintains the temperature of the first contact portion 12 at the first target temperature. The standby state is maintained until the elapsed time from when the cosmetic device 10 is in the standby state does not exceed a predetermined time (5 minutes in the present embodiment) (S406: no). On the other hand, when the time elapsed since the beauty appliance 10 is in the standby state exceeds the predetermined time (yes in S406), the control unit 15 automatically turns off the power supply (S407).

Next, an example of the operation of the cosmetic device 10 in the second mode will be described with reference to the flowchart of fig. 8.

When the user operates the switch unit 16 to turn on the power supply (S500) and selects the second mode (S501), the control unit 15 heats the second heating element 34 to raise the temperature of the second contact portion 13 to a predetermined operation temperature (30 degrees in the present embodiment) (S502). Although not shown in the flowchart, the control unit 15 heats the first heat generator 31 to raise the first contact portion 12 to the standby temperature (30 degrees).

When the second contact portion 13 is heated to the predetermined treatment temperature, the control portion 15 maintains the second contact portion 13 at the predetermined treatment temperature (S503), and the cosmetic device 10 is in the standby state. Further, the control unit 15 starts measuring the time elapsed from when the beauty appliance 10 is placed in the standby state.

When the user holds the beauty device 10 in the standby state and brings the second contact portion 13 into contact with the skin, a current flows to the second contact portion 13, the detection portion 14 detects this (yes in S504), and the control portion 15 starts the operation in the second mode (S505). The control unit 15 causes a second current to flow to the second contact portion 13 while maintaining the temperature of the second contact portion 13 at a predetermined operation temperature, and drives the second vibration motor 36.

When the user does not start using the beauty treatment apparatus 10, that is, does not grip the beauty treatment apparatus 10 in the standby state, and keeps the state in which the second contact portion 13 is not in contact with the skin, and does not perform skin detection, even though the user grips the beauty treatment apparatus 10 in the standby state (no in S504), the control portion 15 maintains the second contact portion 13 at the operation temperature. The standby state of the beauty appliance 10 is maintained until the elapsed time from when the beauty appliance 10 is in the standby state does not exceed a predetermined time (5 minutes in the present embodiment) (S506: no). On the other hand, when the time elapsed since the beauty appliance 10 is in the standby state exceeds the predetermined time (yes in S506), the control unit 15 automatically turns off the power supply (S507).

Next, an example of the operation of the beauty device 10 in the third mode will be described with reference to the flowchart of fig. 9.

When the user operates the switch unit 16 to turn on the power supply (S600) and selects the third mode (S601), the control unit 15 heats the first and

second heat generators

31 and 34 to raise the temperature of the first and

second contact portions

12 and 13 to the first target temperature (38 degrees) (S602).

When the first contact portion 12 and the second contact portion 13 reach the first target temperature, the control portion 15 maintains the first contact portion 12 and the second contact portion 13 at the first target temperature (S603), and the beauty appliance 10 is in a standby state. Further, the control unit 15 starts measuring the time elapsed from when the beauty appliance 10 is placed in the standby state.

When the user holds the beauty device 10 in the standby state and brings the first contact portion 12 or the second contact portion 13 into contact with the skin, if the first contact portion 12 is in contact with the skin, the detection signal flows to the first contact portion 12, the detection portion 14 detects this (yes in S604), and the control portion 15 starts the operation of the first hot mode (S606). The control unit 15 raises the temperature of the first contact portion 12 to a second target temperature (41 degrees), and maintains the second contact portion 13 at the first target temperature.

When the user brings the second contact portion 13 into contact with the skin, a current flows to the second contact portion 13, the detection portion 14 detects this (yes in S604 and no in S605), and the control portion 15 starts the operation of the second thermal mode (S607). The control unit 15 sets the second contact portion 13 to the second target temperature (41 degrees) and maintains the first contact portion 12 at the first target temperature.

When the user does not start using the beauty appliance 10, that is, does not grip the beauty appliance 10 in the standby state, but keeps the beauty appliance 10 in the standing state, or holds the beauty appliance 10 in the standby state, but keeps the first contact portion 12 or the second contact portion 13 in a state of not contacting the skin and does not perform skin detection (S604: no), if the standby state is within a predetermined time (5 minutes in the present embodiment), the control portion 15 maintains the first contact portion 12 and the second contact portion 13 at the first target temperature (S608: no). On the other hand, when the standby state of the beauty appliance 10 has elapsed for a predetermined time (S608: YES), the control unit 15 automatically turns off the power supply (S609).

As described above, in the present embodiment, as in embodiment 1, the first contact portion 12 or the second contact portion 13 is at the first target temperature in the state where the beauty appliance 10 is not in contact with the user, and is at the second target temperature higher than the first target temperature in the state where the beauty appliance 10 is in contact with the user, so that energy consumption can be reduced as compared with the case where the first contact portion 12 or the second contact portion 13 is continuously maintained at the second target temperature from the state of not being in contact with the beauty appliance 10 to the state of being in contact with the beauty appliance. Further, since the temperature change of the first contact portion 12 or the second contact portion 13 is performed in a series of operations before the cosmetic device 10 starts to be used, the user can smoothly start using the cosmetic device 10.

The present invention is not limited to the embodiments described above and illustrated in the drawings, and can be modified as follows, for example.

(1) In the above embodiment, the light emission systems of the plurality of light emitting

units

21, 22, 23, and 24 are exemplified, but the light emission systems of the light emitting units can be arbitrarily changed.

(2) In the above embodiment, the beauty device 10 has two contact portions, but the invention is not limited thereto, and the beauty device 10 may have only one contact portion or three or more contact portions.

(3) In the above embodiment, the case where the beauty device 10 has three use modes has been exemplified, but the use mode of the beauty device 10 may be one, or four or more.

(4) In the above embodiment, the state in which the beauty device 10 is in contact with the user is the state in which the beauty device 10 is held and the first abutting portion 12 or the second abutting portion 13 abuts against the skin, but the present invention is not limited to this, and the state in which the beauty device 10 is held can be the state in which the beauty device 10 is in contact with the user even if the first abutting portion 12 and the second abutting portion 13 do not contact the skin. In this case, the detection unit may be, for example, an acceleration sensor that detects the operation of picking up the beauty device, a pressure sensor that detects the gripping of the beauty device, a temperature sensor that detects the temperature of the hand, an optical sensor (photoelectric sensor) that detects the cutting of light by the hand, a vein recognition sensor (infrared light + infrared sensor) that reads the vein of the hand, or the like.

(5) In the above embodiment, the case where the second target temperature is higher than the first target temperature is exemplified, but the present invention is not limited thereto, and the second target temperature can be made lower than the first target temperature. Specifically, for example, the first target temperature may be set to 20 degrees and the second target temperature may be set to 10 degrees, or the first target temperature may be set to 38 degrees and the second target temperature may be set to 30 degrees. In this case, for example, a cooling device configured to cool the contact portion, such as a cooling device using a thermoelectric element such as a peltier element, may be used, and the second target temperature may be set to be lower than the first target temperature. Thereby, the cooling massage can be performed by using the beauty device.
