However, in the above-mentioned cosmetic device, there is a desire to add a function of heating the contact portion in order to provide a user with a comfortable feeling. In this case, it is desired to find a way to reduce energy consumption.

Summary of the invention

The present invention has been made based on the above-mentioned circumstances, and an object of the present invention is to provide a cosmetic device having a function of heating a contact portion and capable of reducing energy consumption.

Technical means to solve problems

The beauty device of the present invention is a beauty device that is held and used, and includes: a contact portion that contacts the skin; a detection portion that detects a state in which the beauty device is in contact with a user; and a control portion that, based on a detection result of the detection portion, sets the contact portion to a first target temperature when the beauty device is not in contact with the user, and sets the contact portion to a second target temperature that is higher than the first target temperature when the beauty device is in contact with the user.

The state in which the beauty device is not in contact with the user and the state in which the beauty device is in contact with the user include the following modes. That is, the state in which the beauty device is not in contact with the user is a state in which the beauty device is not held, and the state in which the beauty device is in contact with the user is a state in which the beauty device is held but the contact portion is not in contact with the skin. In addition, the state in which the beauty device is not in contact with the user is a state in which the beauty device is not held, and the state in which the beauty device is held but the contact portion is not in contact with the skin, and the state in which the beauty device is in contact with the user is a state in which the beauty device is held and the contact portion is in contact with the skin.

Effects of the Invention

According to the present invention, the contact portion becomes the first target temperature when the beauty device is not in contact with the user, and becomes the second target temperature higher than the first target temperature when the beauty device is in contact with the user. Therefore, compared with the case where the contact portion continuously maintains the second target temperature from the state where the beauty device is not in contact with the user to the state where the beauty device is in contact with the user, energy consumption can be reduced. In addition, since the temperature change of the contact portion is performed in a series of actions before starting to use the beauty device, the user can smoothly start using the beauty device.

Furthermore, when the contact portion is heated to the first target temperature in a state where the cosmetics device is not in contact with the user, the cool feeling when the cosmetics device is used can be alleviated.

Furthermore, by setting the second target temperature to a temperature most suitable for the treatment 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, thereby alleviating the user's stress.

In addition, when the contact portion contacts the skin at the beginning of use of the beauty device, if the difference between the user's skin temperature and the temperature of the contact 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 user's skin temperature, the difference between the user's skin temperature and the temperature of the contact portion at the beginning of use of the beauty device can be reduced, and the user can be less likely to feel uncomfortable.

DETAILED DESCRIPTION

Preferred embodiments of the present invention are shown below.

The cosmetic device of the present invention has a gripping portion, and the detection portion may be provided on the gripping portion. According to such a structure, since the portion having the detection portion does not need to be provided separately from the gripping portion, the cosmetic device can be miniaturized. In addition, when the detection portion is provided on the heated contact portion, the detection portion may malfunction, but by providing the detection portion on the gripping portion, such malfunction can be less likely to occur.

In addition, the beauty device of the present invention may also be configured such that the temperature gradient of the abutting portion rising from the first target temperature to the second target temperature is smaller than the temperature gradient of the abutting portion rising to the first target temperature. According to such a structure, the abutting portion rises slowly to the second target temperature, thereby preventing excessive heating (overshoot) of the abutting portion. In addition, such temperature control performed by the control unit is implemented under normal use environment.

In addition, the beauty device of the present invention can also be configured so that when the hand contacts the holding portion and the skin contacts 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 structure, when the contact portion contacts the skin, the contact portion begins to rise to the second target temperature. Therefore, compared with the case where the contact portion begins to rise to the second target temperature when the beauty device is held but the contact portion is not in contact with the skin, energy consumption can be further reduced. In addition, compared with the case where the contact portion rises to the second target temperature from the initial contact with the skin, the burden on the skin can be reduced.

<Example 1>

Hereinafter, Example 1 which embodies the present invention will be described in detail with reference to FIGS. 1 to 6 .

The cosmetic device 10 in this embodiment is a cosmetic device that a user holds with his/her hand and has an overall elongated heart-shaped flat shape as shown in Fig. 1. The cosmetic device 10 has a wireless charging function and is charged by a charger (not shown).

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

The beauty device 10 has three usage modes. When the switch portion 16 of the beauty device 10 is operated to turn on the power, the first abutting portion 12 and the second abutting portion 13 are both above 30 degrees regardless of the usage mode. The first mode is a mode in which a weak current flows to the first abutting portion 12 to heat it, the second mode is a mode in which a weak current flows to the second abutting portion 13 to heat it, and the third mode is a mode in which only a weak current flows to both the first abutting portion 12 and the second abutting portion 13, that is, a mode in which only the first abutting portion 12 and the second abutting portion 13 are heated. The temperature of the first abutting portion 12 in the first mode is higher than the temperature of the second abutting portion 13 in the second mode. In addition, the temperatures of the first abutting portion 12 and the second abutting portion 13 in the third mode are higher than the temperature of the second abutting portion 13 in the second mode.

As shown in FIG2 , the gripping portion 11 includes an inner housing 18 that accommodates a circuit substrate 17 and the like therein, and an outer cover 19 that covers the outer surface of the inner housing 18. The outer peripheral surface of the gripping portion 11 (the right side surface in FIG1 ) is in a shape that is curved outward. As a result, the outer peripheral surface of the gripping portion 11 is easily fitted to the palm, making it easy to grip and thus easy to perform an operation. In addition, the user grips the gripping portion 11 with the outer peripheral surface of the gripping portion 11 in the direction of the palm, so that the range of the user's finger contact on the outer surface of the gripping portion 11 can be pre-conceived, and the touch pad 37 described later can be arranged in an appropriate position.

The inner housing 18 includes a first housing 18F and a second housing 18S that fit together. The first housing 18F and the second housing 18S are fixed in a fitted state by a plurality of screws N10 and sealed by a waterproof packing 57 .

A battery E serving 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 wireless charging receiving coil 50 , the first contact unit 12 and the second contact unit 13 , and the plurality of light emitting units 21 , 22 , 23 , and 24 are fixed to the inner housing 18 .

The switch unit 16 is fixed to the first housing 18F by screws N12. The switch unit 16 is pressed to turn the power on and off and switch the use mode. The switch unit 16 is electrically connected to a circuit board 17 on which a microcomputer constituting the control unit 15 and the detection unit 14 is mounted.

The circuit board 17 is fixed to the first housing 18F by screws N11. The receiving coil 50 is mounted on the first housing 18F, covered by the cover 19, and sealed by the sealing member 52. The first housing 18F is provided with a control device 53 for controlling wireless charging of the beauty 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 in a cap shape and are made of metal or resin and have a conductive coating formed on the entire surface. The coating of the first contact portion 12 and the coating of the second contact portion 13 are both electrically connected to the circuit board 17 via screws N14.

The first contact portion 12 and the second contact portion 13 have different curved shapes.

As shown in Fig. 1 , the first contact portion 12 has a shape in which two curved protrusions are arranged in a row. 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 with the middle portion in the vertical direction in Fig. 1 being recessed to the right. The second contact portion 13 is gently curved with a smaller curvature than the protrusion of the first contact portion 12 so as to follow the curve of the cheek of a person.

By making the first contact portion 12 and the second contact portion 13 have different curved shapes, it is possible to select a contact portion with a shape that is easily fitted to either the first contact portion 12 or the second contact portion 13 to match the shape of the treatment target surface, thereby improving the treatment effect. In addition, since the first contact portion 12 and the second contact portion 13 can be easily distinguished by the difference in shape, the use mode can be easily determined by which of the first contact portion 12 and the second contact portion 13 contacts the skin.

A first heating element 31 for heating the first contact portion 12 , a first temperature sensor 32 for measuring the temperature of the first contact portion 12 , and a first vibration motor 33 for vibrating the first contact portion 12 are provided between the first contact portion 12 and the inner case 18 .

2 , the portion of the inner housing 18 covered by the first contact portion 12 is bent along the shape of the inner surface of the first contact portion 12. Thus, the first heating element 31 can be arranged close to or in contact with the inner surface of the first contact portion 12, and the first contact portion 12 can be heated quickly.

A second heating element 34 for heating the second contact portion 13 , a second temperature sensor 35 for measuring the temperature of the second contact portion 13 , and a second vibration motor 36 for vibrating the second contact portion 13 are provided between the second contact portion 13 and the inner case 18 .

2 , the portion of the inner housing 18 covered by the second contact portion 13 is bent along the shape of the inner surface of the second contact portion 13. Thus, the second heating element 34 can be arranged close to or in contact with the inner surface of the second contact portion 13, and the second contact portion 13 can be heated quickly.

The first heating element 31 and the second heating element 34 are both planar thin-film heaters with heat-insulating sheets. The first heating element 31 and the second heating element 34 are both waterproofed by a packing (not shown).

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

As shown in FIG1 , the plurality of light emitting parts 21, 22, 23, 24 include a first light emitting part 21 arranged at a position separating the first contact part 12 and the second contact part 13, and three light emitting parts (hereinafter referred to as the second light emitting part 22, the third light emitting part 23, and the fourth light emitting part 24) lit on the front side of the outer cover 19. The first light emitting part 21, the second light emitting part 22, the third light emitting part 23, and the fourth light emitting part 24 are composed of light emitting diodes (LEDs), and are electrically connected to the circuit board 17, respectively. The holder 55 holding the second light emitting part 22, the third light emitting part 23, and the fourth light emitting part 24 is fixed to the second housing 18S by screws N13.

The first light emitting unit 21 indicates the state of the beauty device 10, such as which usage mode the beauty device 10 is in, by emitting light in different ways (blinking, lighting, different colors). The second light emitting unit 22 remains lit when the beauty device 10 is in the first mode, the third light emitting unit 23 remains lit when the beauty device 10 is in the second mode, and the fourth light emitting unit 24 remains lit when the beauty device 10 is in the third mode. When the power of the beauty device 10 is turned off, 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 all turned off.

As shown in Fig. 2, the outer cover 19 includes a first cover 19F covering the first housing 18F and a second cover 19S covering the second housing 18S. The first cover 19F and the second cover 19S are held in a fitted state by locking portions 58, 59 provided on the outer peripheral edge portions.

The second cover 19S has a through-hole 62 for inserting the touch panel 37. The touch panel 37 is made of metal or resin, and has a conductive plated film formed on the entire surface. When the touch panel 37 is inserted into the insertion hole 62, the connector portion (not shown) on the back of the touch panel 37 is in contact with the terminal 54. The terminal 54 is mounted on the second housing 18S and is electrically connected to the circuit board 17.

The cosmetic device 10 can form a closed circuit through the human body when the hand contacts the grip 11 and the skin contacts the first contact portion 12 or the second contact portion 13, so that a weak current flows to the first contact portion 12 or the second contact portion 13. Specifically, when the use mode of the cosmetic device 10 is selected as the first mode, when a part of the human body such as a hand or a finger contacts the touch pad 37 of the grip 11 and another part of the human body such as a cheek contacts 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 addition, when the use mode of the cosmetic device 10 is selected as the second mode, when a part of the human body such as a hand or a finger contacts the touch pad 37 of the grip 11 and another part of the human body such as a cheek contacts the second contact portion 13, a potential difference is generated between the touch pad 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 released from the grip portion 11 or the skin is released 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 stops.

As shown in Figure 3, the control unit 15 is connected to a battery E, a switch unit 16, a first light-emitting unit 21, a second light-emitting unit 22, a third light-emitting unit 23, a fourth light-emitting unit 24, a detection unit 14, a touch pad 37, a first abutment unit 12, a first heating element 31, a first temperature sensor 32, a first vibration motor 33, a second abutment unit 13, a second heating element 34, a second temperature sensor 35 and a second vibration motor 36.

When the power of the cosmetic device 10 is turned on, the control unit 15 supplies pulse current between the touch panel 37 and the first contact part 12 and between the touch panel 37 and the second contact part 13 for human body detection. The detection pulse current is not supplied continuously but at fixed time intervals.

When the touch pad 37 is connected to the first contact part 12 via the human body and current flows, the detection part 14 detects this. In addition, when the touch pad 37 is connected to the second contact part 13 via the human body and current flows, the detection part 14 detects this. Thus, the detection part 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 this embodiment, the state of not holding the beauty device 10 and the state of holding the beauty device 10 but the first contact part 12 and the second contact part 13 are not in contact with the skin are the states of the beauty device 10 not contacting the user. And the state of holding the beauty device 10 and the first contact part 12 or the second contact part 13 contacting the skin is the state of the beauty device 10 contacting the user.

The control unit 15 performs on-off control of the first heating element 31 based on the detection result of the detection unit 14, the selected use mode, and the input signal from the first temperature sensor 32 so that the temperature of the first contact portion 12 becomes a predetermined temperature. The control unit 15 performs on-off control of the second heating element 34 based on the detection result of the detection unit 14, the selected use mode, and the input signal from the second temperature sensor 35 so that the temperature of the second contact portion 13 becomes a predetermined temperature.

The control unit 15 controls the first heating element 31 and the second heating element 34 in the first mode and the third mode as follows. When 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 abutting portion 12 or the second abutting portion 13 rises 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 abutting portion 12 or the second abutting portion 13 rises to a second target temperature higher than the first target temperature. At this time, the control unit 15 controls in such a way that the temperature gradient of the first abutting portion 12 or the second abutting portion 13 rising from the first target temperature to the second target temperature is smaller than the temperature gradient of the first abutting portion 12 or the second abutting portion 13 rising from the normal temperature to the first target temperature.

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

The control unit 15 flows a current of substantially one polarity (hereinafter referred to as a first current) to the first contact portion 12 in the first mode, and flows a current of alternating polarity (hereinafter referred to as a second current) 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 (timing function).

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

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

When the user operates the switch unit 16 to turn on the power (S100), the control unit 15 starts measuring the time that has passed since the power of the beauty device 10 was turned on. Then, when the user selects the first mode (S101), the control unit 15 heats the first heating element 31 and raises the temperature of the first contact portion 12 to the first target temperature (38 degrees in this embodiment) (S102). At this time, the control unit 15 rapidly heats the first heating element 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. In addition, although not recorded in the flowchart, the control unit 15 heats the second heating element 34 so that the second contact portion 13 rises to a standby temperature lower than the first target temperature (30 degrees in this embodiment). During this period, the control unit 15 causes the first light-emitting unit 21 to flash slowly 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 unit 15 maintains the first contact portion 12 at the first target temperature (S103), and the beauty device 10 enters a standby state. When the first contact portion 12 reaches or exceeds the first target temperature, the control unit 15 stops heating, and when it reaches or falls below the first target temperature, it continues heating to maintain the first contact portion 12 at the first target temperature. The control unit 15 continues to slowly flash the first light-emitting portion 21 in white, turns on the second light-emitting portion 22, and maintains the third light-emitting portion 23 and the fourth light-emitting portion 24 in an off state.

When the time elapsed from the power supply of the cosmetic device 10 being turned on exceeds a predetermined time (5 minutes in this embodiment) (S104: Yes), the control unit 15 automatically turns off the power supply (S108). The control unit 15 turns off all the light-emitting units 21, 22, 23, and 24, and stops the heating of the first heating element 31 and the second heating element 34. Thus, it is possible to prevent the cosmetic device 10 from being left on for a period of time exceeding a predetermined time, and to prevent wasteful energy consumption.

When the user does not start using, that is, does not hold the beauty device 10 in the standby state but keeps the beauty device 10 in the standby state, or holds the beauty device 10 in the standby state but keeps the first contact part 12 out of contact with the skin and does not perform skin detection (S105: No), the control unit 15 maintains the temperature of the first contact part 12 at the first target temperature.

If the user holds the beauty device 10 in the standby state and brings the first contact part 12 into contact with the skin before the prescribed time has passed since the power of the beauty device 10 was turned on (S104: No), the current flows to the first contact part 12 and the detection part 14 detects this (S105: Yes), and the control part 15 starts the operation of the first mode (S106). Here, when the user brings the first contact part 12 into contact with the skin, the first contact part 12 reaches the first target temperature. The first target temperature of this embodiment is 38 degrees, which is the same as the human body temperature, so it is possible to eliminate the cold feeling when the first contact part 12 is brought into contact with the skin. In addition, the control part 15 resets the timer that starts when the power of the beauty device 10 is turned on, and instead starts measuring the time that has passed since the first contact part 12 came into contact with the skin.

When the operation of the first mode starts, the control unit 15 heats the first heating element 31 and raises the temperature of the first contact portion 12 to the second target temperature (41 degrees in this 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. Thus, the pressure applied to the user's skin can be reduced. In addition, if the temperature is raised rapidly, the so-called overshoot in which the first heating element 31 rises excessively may occur, and as a result, such an excessive rise 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 in operation through the vibration of the first vibration motor 33. The control unit 15 keeps the second contact portion 13 at the standby temperature, and then slowly flashes the first light-emitting portion 21 in white, lights up the second light-emitting portion 22, and maintains the third light-emitting portion 23 and the fourth light-emitting portion 24 in an off state.

When the time elapsed since the first contact part 12 came into contact with the skin exceeds a predetermined time (5 minutes in this embodiment) (S107: Yes), the control part 15 automatically turns off the power supply (S108). The control part 15 turns off all the light-emitting parts 21, 22, 23, and 24, and stops the heating of the first heating element 31 and the second heating element 34. The control part 15 maintains the operation of the first mode while the time elapsed since the first contact part 12 came into contact with the skin does not exceed the predetermined time (S107: No).

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

When the user operates the switch portion 16 to turn on the power (S200), the control portion 15 starts measuring the time that has passed since the power of the beauty device 10 was turned on. Then, when the user selects the second mode (S201), the control portion 15 heats the second heating element 34 and raises the temperature of the second contact portion 13 to a specified treatment temperature (30 degrees in this embodiment) (S202). The treatment temperature of the second mode (a mode in which the second current flows to the second contact portion 13) is set to a temperature slightly lower than the treatment temperature (41 degrees) suitable for the first mode (a mode in which the first current flows to the first contact portion 12). In addition, although not described in the flowchart, the control portion 15 heats the first heating element 31 to raise the first contact portion 12 to a standby temperature (30 degrees). The standby temperature of the first contact portion 12 is the same temperature as the standby temperature of the second contact portion 13 in the first mode. During this period, the control unit 15 causes the first light emitting unit 21 to slowly flash in blue, turns on the third light emitting unit 23, and turns off the second light emitting unit 22 and the fourth light emitting unit 24.

When the temperature of the second contact portion 13 rises to the prescribed treatment temperature, the control unit 15 maintains the second contact portion 13 at the prescribed treatment temperature (S203), and the cosmetic device 10 enters a standby state. When the second contact portion 13 reaches or exceeds the prescribed treatment temperature, the control unit 15 stops heating, and when it reaches or falls below the prescribed treatment temperature, it continues heating to maintain the second contact portion 13 at the treatment temperature. The control unit 15 continues to slowly flash 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. In addition, when the time elapsed from the power supply of the cosmetic device 10 being turned on exceeds a prescribed time (5 minutes in this embodiment) (S204: Yes), the control unit 15 automatically turns off the power supply (S208). The control unit 15 turns off all the light-emitting portions 21, 22, 23, and 24, and stops heating the first heating element 31 and the second heating element 34. Thus, similarly to the first mode, it is possible to prevent the cosmetic device 10 from being left on for a predetermined time or longer, thereby preventing wasteful energy consumption.

When the user does not start use, that is, does not hold the beauty device 10 in the standby state but keeps the beauty device 10 in the standby state, or holds the beauty device 10 in the standby state but keeps the second contact part 13 out of contact with the skin and does not perform skin detection (S205: No), the control unit 15 maintains the second contact part 13 at the treatment temperature.

If the user holds the beauty device 10 in the standby state and makes the second contact part 13 contact the skin before the prescribed time has passed since the power of the beauty device 10 was turned on (S204: No), the current flows to the second contact part 13, and the detection unit 14 detects this (S205: Yes), and the control unit 15 starts the operation of the second mode (S206). In addition, the control unit 15 resets the timer that starts when the power of the beauty device 10 is turned on, and instead starts to measure the time that has passed since the second contact part 13 contacted the skin. The control unit 15 causes the second current to flow to the second contact part 13 while keeping the temperature of the second contact part 13 at the prescribed treatment temperature, and drives the second vibration motor 36. The user senses that the second mode is operating through the vibration of the second vibration motor 36. During this period, the control unit 15 maintains the temperature of the first contact portion 12 at the standby temperature, lights up the first light emitting unit 21 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 since the second contact part 13 came into contact with the skin exceeds a predetermined time (5 minutes in this embodiment) (S207: Yes), the control part 15 automatically turns off the power supply (S208). In addition, the control part 15 turns off all the light-emitting parts 21, 22, 23, and 24, and stops the heating of the first heating element 31 and the second heating element 34. The control part 15 maintains the operation of the second mode while the time elapsed since the second contact part 13 came into contact with the skin does not exceed the predetermined time (S207: No).

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

When the user operates the switch unit 16 to turn on the power (S300), the control unit 15 starts to measure the time that has passed since the power of the beauty device 10 was turned on. Then, when the user selects the third mode (S301), the control unit 15 heats the first heating element 31 and the second heating element 34 to raise the temperature of the first contact portion 12 and the second contact portion 13 to the first target temperature (38 degrees) (S302). During this period, the control unit 15 makes the first light-emitting unit 21 slowly flash 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 unit 15 maintains the first contact portion 12 and the second contact portion 13 at the first target temperature (S303), and the cosmetic device 10 enters a standby state. When the first contact portion 12 and the second contact portion 13 become higher than the first target temperature, the control unit 15 stops heating, and when they become lower than the first target temperature, they continue heating to maintain the first contact portion 12 and the second contact portion 13 at the first target temperature. The control unit 15 lights up the first light-emitting portion 21 in red, lights up the fourth light-emitting portion 24, and turns off the second light-emitting portion 22 and the third light-emitting portion 23. In addition, when the time elapsed from the power supply of the cosmetic device 10 being turned on exceeds a predetermined time (5 minutes in this embodiment) (S304: Yes), the control unit 15 automatically turns off the power supply (S310). The control unit 15 turns off all the light-emitting portions 21, 22, 23, and 24, and stops heating the first heating element 31 and the second heating element 34. Thus, similarly to the first mode and the second mode, it is possible to prevent the cosmetic device 10 from being left on for a predetermined time or longer, thereby preventing wasteful energy consumption.

When the user does not start using, that is, does not hold the beauty device 10 in the standby state but keeps the beauty device 10 in the standby state, or holds the beauty device 10 in the standby state but keeps neither the first contact part 12 nor the second contact part 13 in contact with the skin and does not perform skin detection (S305: Yes), the control unit 15 maintains the first contact part 12 and the second contact part 13 at the first target temperature.

When the prescribed time has not passed since the power of the cosmetic device 10 was turned on (S304: No), if the user holds the cosmetic device 10 in the standby state and makes the first contact part 12 or the second contact part 13 contact the skin, then when the first contact part 12 contacts the skin, a detection signal flows to the first contact part 12, and the detection part 14 detects this (S305: Yes, S306: Yes), and the control part 15 starts the operation of the first heat mode (S307). In addition, the control part 15 resets the timer started when the power of the cosmetic device 10 is turned on, and instead starts to measure the time that has passed since the first contact part 12 contacted the skin. The control part 15 raises the temperature of the first contact part 12 to the second target temperature (41 degrees) and keeps the second contact part 13 at the first target temperature. The control part 15 continues to light up the first light-emitting part 21 in red, lights up the fourth light-emitting part 24, and maintains the second light-emitting part 22 and the third light-emitting part 23 in an off state.

When the user makes the second contact part 13 contact the skin, the current flows to the second contact part 13, and the detection part 14 detects this (S305: Yes, S306: No), and the control part 15 starts the operation of the second heat mode (S308). In addition, the control part 15 resets the timer that starts when the power of the beauty device 10 is turned on, and instead starts to measure the time that has passed since the second contact part 13 contacted the skin. The control part 15 sets the second contact part 13 to the second target temperature (41 degrees) and keeps the first contact part 12 at the first target temperature. The control part 15 continues to light up the first light-emitting part 21 in red, lights up the fourth light-emitting part 24, and maintains the second light-emitting part 22 and the third light-emitting part 23 in the off state.

When the time elapsed since the first contact part 12 or the second contact part 13 contacts the skin exceeds a predetermined time (5 minutes in this embodiment) (S309: Yes), the control part 15 automatically turns off the power supply (S310). The control part 15 turns off all the light-emitting parts 21, 22, 23, and 24, and stops the heating of the first heating element 31 and the second heating element 34. The control part 15 maintains the operation of the third mode while the time elapsed since the first contact part 12 or the second contact part 13 contacts the skin does not exceed the predetermined time (S309: No).

Furthermore, the cosmetic device 10 of the present embodiment can be changed to another usage mode in the middle of the usage mode.

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

In addition, for example, when the switch portion 16 of the beauty device 10 is operated in the standby state of the third mode to switch to the second mode, the second contact portion 13 becomes 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 treatment temperature (30 degrees) of the second mode. Therefore, compared with the case where the second contact portion 13 is lowered from the second target temperature to the treatment temperature of the second mode, it can be lowered to the treatment temperature of the second mode in a short time.

Furthermore, when the use mode is changed to another use mode in the middle of the use mode, the control unit 15 resets the timer at the same time when the other use mode is selected, and instead starts measuring the time elapsed from the time when the other mode is selected.

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

The cosmetic device 10 of the present embodiment is a cosmetic device 10 that is held and used, and includes: a first contact portion 12 and a second contact portion 13 that are in contact with the skin; a detection portion 14 that detects whether the cosmetic device 10 is in a state of not being in contact with the user or in a state of being in contact with the user; and a control portion 15 that makes the first contact portion 12 or the second contact portion 13 a first target temperature when the cosmetic device 10 is not in contact with the user, and makes the first contact portion 12 or the second contact portion 13 a second target temperature that is higher than the first target temperature when the cosmetic device 10 is in contact with the user. According to this structure, the first contact portion 12 or the second contact portion 13 is at the first target temperature when the cosmetic device 10 is not in contact with the user, and is at the second target temperature that is higher than the first target temperature when the cosmetic device 10 is in contact with the user. Therefore, energy consumption can be reduced compared to a case where the first contact portion 12 or the second contact portion 13 is continuously maintained at the second target temperature during a period from a state of non-contact with the cosmetic device 10 to a state of contact with the cosmetic device 10. In addition, since the temperature change of the first contact portion 12 or the second contact portion 13 is performed during a series of actions before starting to use the cosmetic device 10, the user can start using the cosmetic device 10 smoothly.

Furthermore, since the first contact portion 12 and the second contact portion 13 are heated to the first target temperature in a state where the cosmetics device 10 is not in contact with the user, the cold feeling when the cosmetics device 10 is used can be alleviated.

Furthermore, by setting the second target temperature to a temperature most suitable for the treatment 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, thereby alleviating the user's nervousness.

In addition, when the first contact part 12 or the second contact part 13 is brought into contact with the skin at the beginning of use of the beauty device 10, if the difference between the user's skin temperature and the temperature of the contact part 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 user's skin temperature, the difference between the user's skin temperature and the temperature of the first contact part 12 or the second contact part 13 at the beginning of use of the beauty device 10 can be reduced, and the user can be less likely to feel uncomfortable.

In addition, the cosmetic device 10 of the present embodiment includes the gripping portion 11, and the detection portion 14 is provided on the gripping portion 11. According to this structure, since it is not necessary to provide the portion having the detection portion 14 separately from the gripping portion 11, the cosmetic device 10 can be miniaturized. In addition, when the detection portion 14 is provided on the first contact portion 12 or the second contact portion 13 to be heated, although the detection portion 14 may malfunction, by providing the detection portion 14 on the gripping portion 11, such malfunction can be less likely to occur.

In addition, in the cosmetic device 10 of the present embodiment, the temperature gradient of the first abutting portion 12 or the second abutting portion 13 from the first target temperature to the second target temperature is smaller than the temperature gradient of the first abutting portion 12 or the second abutting portion 13 from the first target temperature to the first target temperature. According to this structure, the first abutting portion 12 or the second abutting portion 13 slowly rises to the second target temperature, so that excessive heating (overshoot) of the first abutting portion 12 or the second abutting portion 13 can be prevented.

In addition, the beauty device 10 of the present embodiment is configured such that when the hand contacts the grip portion 11 and the skin contacts the first contact portion 12 or the second contact portion 13, a closed circuit is formed through 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 contacts the skin, the first contact portion 12 or the second contact portion 13 starts to rise to the second target temperature. Therefore, compared with the case where the first contact portion 12 or the second contact portion 13 starts to rise to the second target temperature when the beauty device 10 is held but the first contact portion 12 or the second contact portion 13 is not in contact with the skin, energy consumption can be further reduced. In addition, the burden on the skin can be reduced compared to the case where the temperature of the first contact portion 12 or the second contact portion 13 rises to the second target temperature from the initial contact with the skin.

<Example 2>

Next, a cosmetic device according to a second embodiment of the present invention will be described with reference to FIGS. 7 to 9 .

In the beauty device of this embodiment, the timing at which the control unit starts measuring the elapsed time is different from that in Embodiment 1. In addition, the same reference numerals are given to the same configurations as those in Embodiment 1, and duplicate descriptions are omitted.

The cosmetic device 10 of this embodiment is provided with a detection unit 14 for detecting the gripping portion 11, the first contact portion 12, and the second contact portion 13, a detection unit 14 for detecting whether the cosmetic device 10 is in a non-contact state or in a contact state with the user, and a control unit 15 for controlling the temperature of the first contact portion 12 and the second contact portion 13 based on the detection result of the detection unit 14. In addition, the cosmetic device 10 has three usage modes as in the first embodiment.

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

When the user operates the switch unit 16 to turn on the power (S400) and select the first mode (S401), the control unit 15 heats the first heating element 31 to raise the temperature of the first contact portion 12 to the first target temperature (38 degrees in this embodiment) (S402). In addition, although not described in the flowchart, the control unit 15 heats the second heating element 34 to raise the temperature of the second contact portion 13 to a standby temperature lower than the first target temperature (30 degrees in this embodiment).

When the first contact portion 12 reaches the first target temperature, the control unit 15 maintains the first contact portion 12 at the first target temperature (S403), and the cosmetics device 10 enters the standby state. In addition, the control unit 15 starts measuring the time elapsed since the cosmetics device 10 entered the standby state.

When the user holds the cosmetic device 10 in the standby state and brings the first contact part 12 into contact with the skin, current flows to the first contact part 12 , the detection part 14 detects this ( S404 : Yes), and the control part 15 starts the operation of the first mode ( S405 ).

When the operation of the first mode starts, the control unit 15 heats the first heating element 31 to raise the temperature of the first contact portion 12 to the second target temperature (41 degrees in this embodiment). At this time, as in Embodiment 1, 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. The control unit 15 causes the first current to flow to the first contact portion 12 to drive the first vibration motor 33.

When the user does not start using, that is, does not hold the beauty device 10 in the standby state and keeps the beauty device 10 in the standby state, or holds the beauty device 10 in the standby state but keeps the first contact part 12 out of contact with the skin and does not perform skin detection (S404: No), the control unit 15 maintains the temperature of the first contact part 12 at the first target temperature. The standby state is maintained while the time elapsed from the beauty device 10 entering the standby state does not exceed the prescribed time (5 minutes in this embodiment) (S406: No). On the other hand, if the time elapsed from the beauty device 10 entering the standby state exceeds the prescribed time (S406: Yes), the control unit 15 automatically turns off the power supply (S407).

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

When the user operates the switch unit 16 to turn on the power (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 treatment temperature (30 degrees in this embodiment) (S502). In addition, although not described in the flowchart, the control unit 15 heats the first heating element 31 to raise the temperature of the first contact portion 12 to the standby temperature (30 degrees).

When the second contact part 13 is heated to the predetermined treatment temperature, the control unit 15 maintains the second contact part 13 at the predetermined treatment temperature (S503), and the cosmetic device 10 enters the standby state. In addition, the control unit 15 starts measuring the time elapsed since the cosmetic device 10 entered the standby state.

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

When the user does not start using, that is, does not hold the beauty device 10 in the standby state and keeps the beauty device 10 in the standby state, or holds the beauty device 10 in the standby state but keeps the second contact part 13 out of contact with the skin and does not perform skin detection (S504: No), the control unit 15 maintains the second contact part 13 at the treatment temperature. The standby state of the beauty device 10 is maintained during the period when the time elapsed from the beauty device 10 entering the standby state does not exceed the prescribed time (5 minutes in this embodiment) (S506: No). On the other hand, when the time elapsed from the beauty device 10 entering the standby state exceeds the prescribed time (S506: Yes), the control unit 15 automatically turns off the power supply (S507).

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

When the user operates the switch 16 to turn on the power ( S600 ) and selects the third mode ( S601 ), the control unit 15 heats the first heating element 31 and the second heating element 34 to raise the temperature of the first contact portion 12 and the second contact portion 13 to the first target temperature (38 degrees) ( S602 ).

When the first contact part 12 and the second contact part 13 reach the first target temperature, the control unit 15 maintains the first contact part 12 and the second contact part 13 at the first target temperature (S603), and the cosmetic device 10 enters the standby state. In addition, the control unit 15 starts measuring the time elapsed since the cosmetic device 10 entered the standby state.

When the user holds the beauty device 10 in the standby state and makes the first contact part 12 or the second contact part 13 contact the skin, when the first contact part 12 contacts the skin, the detection signal flows to the first contact part 12, the detection part 14 detects this (S604: Yes, S605: Yes), and the control part 15 starts the operation of the first heating mode (S606). The control part 15 raises the temperature of the first contact part 12 to the second target temperature (41 degrees) and keeps the second contact part 13 at the first target temperature.

When the user makes the second contact part 13 contact the skin, the current flows to the second contact part 13, the detection part 14 detects this (S604: Yes, S605: No), and the control part 15 starts the operation of the second heating mode (S607). The control part 15 sets the second contact part 13 to the second target temperature (41 degrees) and keeps the first contact part 12 at the first target temperature.

When the user does not start to use, that is, does not hold the beauty device 10 in the standby state and keeps the beauty device 10 in the standby state, or holds the beauty device 10 in the standby state but keeps the first contact part 12 and the second contact part 13 in a state where they are not in contact with the skin and do not perform skin detection (S604: No), if the standby state is within a prescribed time (5 minutes in this embodiment), the control unit 15 maintains the first contact part 12 and the second contact part 13 at the first target temperature (S608: No). On the other hand, when the standby state of the beauty device 10 exceeds the prescribed time (S608: Yes), the control unit 15 automatically turns off the power supply (S609).

As described above, in this embodiment, similarly to the first embodiment, the first contact portion 12 or the second contact portion 13 becomes the first target temperature when the cosmetics device 10 is not in contact with the user, and becomes the second target temperature which is lower than the first target temperature when the cosmetics device 10 is in contact with the user, so that energy consumption can be reduced compared to the case where the first contact portion 12 or the second contact portion 13 continuously maintains the second target temperature from the state of not in contact with the cosmetics device 10 to the state of contact. In addition, the temperature change of the first contact portion 12 or the second contact portion 13 is performed in a series of actions before starting to use the cosmetics device 10, so the user can start using the cosmetics device 10 smoothly.

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

(1) In the above-mentioned embodiment, the light emitting modes of the plurality of light emitting units 21, 22, 23, and 24 are exemplified, but the light emitting modes of the light emitting units can be arbitrarily changed.

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

(3) In the above embodiment, the cosmetics device 10 has three usage modes. However, the cosmetics device 10 may have one usage mode or four or more usage modes.

(4) In the above-mentioned embodiment, the state in which the beauty device 10 is in contact with the user is a 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, but the present invention is not limited thereto. Even if the first contact portion 12 and the second contact portion 13 are not in contact with the skin, the state in which the beauty device 10 is held can be set as a state in which the beauty device 10 is in contact with the user. In this case, the detection unit can be, for example, an acceleration sensor that detects the action of picking up the beauty device, a pressure sensor that detects that the beauty device is held, a temperature sensor that detects the temperature of the hand, a light sensor (photoelectric sensor) that detects light cut by the hand, a vein confirmation sensor (infrared light + infrared sensor) that reads the veins of the hand, and the like.

(5) In the above embodiment, the case where the second target temperature is higher than the first target temperature is illustrated, but the present invention is not limited thereto, and the second target temperature can be lower than the first target temperature. Specifically, for example, the first target temperature can be set to 20 degrees and the second target temperature can be set to 10 degrees, or the first target temperature can be set to 38 degrees and the second target temperature can be set to 30 degrees. In such a case, a cooling device configured to cool the abutting portion, such as a cooling device using a thermoelectric element such as a Peltier element, can be used to make the second target temperature lower than the first target temperature. Thus, a beauty device can be used for cooling massage.
