Description

[0001]
[Industrial application fields]
The present invention relates to a facial device that obtains a facial effect by exerting a physical effect such as heat on the face, and in particular, the present invention relates to a facial device having a function of temporarily extending wrinkles on the face to make it inconspicuous.
[0002]
[Prior art]
Conventionally, as a facial device, for example, a device that generates steam and acts on the face has been proposed. This type of facial device requires a tank or container for storing water, so that the equipment becomes large, and the internal structure becomes complicated because steam is generated. Moreover, replenishment of water before use and disposal of water after use are necessary, and there is a problem that preparation and cleaning up are troublesome.
[0003]
Therefore, a facial device has been proposed in which heat is applied to the face without using steam (see, for example, Patent Literature). In this facial device, a body portion having a grip for hand-held operation is provided with a pair of contact surfaces for performing a facial treatment by selectively contacting the face. One contact surface is heated by a heater, and the other contact surface is cooled by a Peltier element. The heated contact surface and the cooled contact surface are alternately brought into contact with the face, thereby activating the skin by applying a temperature difference due to cooling and cooling to the skin.

JP-A 63-257556
[Problems to be solved by the invention]
However, the facial device described above is intended to activate the skin using a temperature difference, and a facial effect that stretches the wrinkles of the face cannot be expected. In addition, since the user can arbitrarily determine the contact time when the heated contact surface and the cooled contact surface are alternately brought into contact with the face, the facial effect varies, and excessive heating or Cooling may damage the skin.
[0006]
The present invention has been made paying attention to the above-mentioned problem, and it is possible to temporarily stretch the wrinkles of the face so that it is not noticeable. An object is to provide a facial device that can be prevented.
[0007]
[Means for Solving the Problems]
The facial device according to the present invention is a facial device in which first and second contact surfaces for performing a facial treatment by selectively contacting the face are provided at the front end portion of the main body having a grip. A negative potential setting means for setting the negative contact surface to a negative potential; a heat generating means for applying heat to the first contact surface; a cooling means for cooling the second contact surface; And a control means for controlling each operation of the negative potential setting means, the heat generation means, the cooling means, and the notification means. The control means first operates the negative potential setting means to set the first contact surface to the negative potential, and then stops the operation of the negative potential setting means when the setting time of the facial treatment by the negative potential has elapsed. And operating the heat generating means to heat the first contact surface, starting the operation of the cooling means during the operation of the heat generating means to start cooling the second contact surface, The operation of the heat generating means is stopped when the setting time of the facial treatment by warm heat has elapsed, and then the operation of the cooling means is stopped when the setting time of the facial processing by cooling has elapsed. The control means further operates the notifying means when a setting time of the facial treatment by negative potential has elapsed, when a setting time of the facial processing by heat has elapsed, and when a setting time of the facial treatment by cooling has elapsed. I will let you.
[0008]
In the above-described configuration of the present invention, the “ first and second contact surfaces” are made of a material having good heat conduction, and may be arranged side by side or in opposite directions.
Further, the “notification means” is an alarming notification that generates a buzzer sound, a melody sound, a voice, and the like. The reason for notifying by hearing is that the notification can be understood even when the main body is brought close to the face during the facial treatment.
Further, the “control means ” can be realized by a programmed computer, but can also be realized by a dedicated hardware circuit.
[0009]
From the viewpoint of preventing low temperature burns, the warm heat generating means is preferably configured with a PTC heater, but is not necessarily limited thereto.
[0010]
Moreover, the said cooling means is comprised by a Peltier element, for example, starts operation | movement during the operation | movement of a heat generating means , and precools a 2nd contact surface. By this pre-cooling, the cooling means is sufficiently cooled when the operation of the heat generating means is completed, so that the warmed skin can be rapidly cooled, and the facial effect becomes effective by this rapid cooling.
[0011]
In a preferred embodiment of the present invention, the cooling means includes a Peltier element, a heat radiation fin connected to a heat radiation surface of the Peltier element, and a cooling fan that blows air to the heat radiation fin to dissipate heat. Starts operating simultaneously with the energization of the Peltier element and continues the operation for a certain period after the energization of the Peltier element is cut off. In this way, deterioration of the Peltier element can be delayed.
[0012]
[Action]
At the time of the beautiful face processing, the grip of the main body is held in the hand, and the first contact surface is brought into contact with the face. First, since the first contact surface is set to a negative potential by the negative potential setting means, the cells are activated and the skin surface becomes flexible. When the set time elapses, the operation of the negative potential setting means is stopped and the heat generating means is operated, so that the first contact surface is heated. The first contact surface remains in contact with the face, and the activated skin promotes blood circulation by heat, enhances metabolism, and stretches the skin. Since the notification by sound is performed when the set time has elapsed, it can be seen that the face processing by the negative potential has shifted to the face processing by the heat.
[0013]
When the set time elapses, the operation of the heat generating means is stopped and the first contact surface is naturally cooled. On the other hand, the cooling means is operated to forcibly cool the second contact surface. Since notification by sound is performed when the set time has elapsed, it is instructed to shift from the facial processing by heat to the facial processing by cooling. Therefore, when the cooled second contact surface is brought into contact with the face, the state in which the skin is tightened and the skin surface is stretched is stored, and as a result, the wrinkles on the face are temporarily stretched and become inconspicuous.
When the set time elapses, the operation of the cooling means stops, but when the set time elapses, a sound notification is given, so that it is understood that the facial treatment process has ended.
[0014]

[0020]
A large number of ventilation holes 12 are formed in the main body 1 at appropriate positions except for the grip 10. In particular, the projecting portion 1B provided with the second contact surface 3B is formed with a large number of vent holes 12 so as to promote heat dissipation of the Peltier element 7 described later.
[0021]
As shown in FIG. 2, the protrusions 1 </ b> A and 1 </ b> B of the main body 1 are open at the tip, and the first open portion is covered with a cap 30 </ b> A such as ABS resin having good heat conduction. The second contact surface 3B is formed by covering the contact surface 3A with a cap 30B made of metal such as stainless steel on the other open portion.
[0022]
Inside the cap 30A, as shown in FIG. 3, a PTC (Positive Temperature Coefficient) heater 5 for applying heat to the first contact surface 3A and a negative predetermined potential (this) on the first contact surface 3A In the embodiment, a potential output pad 60 for setting -2000 volts) and a heat insulating material 50 for preventing the heat from acting on the main body 1 are arranged to overlap with each other, and a heater temperature composed of a thermistor. The sensor 51 is arranged in contact with the PTC heater 5.
[0023]
The PTC heater 5 is mainly composed of a ceramic semiconductor and has a property that the resistance value increases in proportion to the temperature increase. When the resistance value of the PTC heater 5 increases, the current decreases and the amount of heat generation decreases, so that the temperature is kept constant. The temperature sensor 51 is for monitoring the temperature of the PTC heater 5 in order to keep the first contact surface 3A at a set temperature.
When the PTC heater 5 is used as a heater as in this embodiment, the occurrence of low temperature burns can be prevented as compared with, for example, a nichrome wire heater.
[0025]
A negative predetermined potential generated by the negative potential generating circuit 6 ( shown in FIG. 4 ) is applied to the potential output pad 60. The negative potential generating circuit 6 is mounted on a main substrate 9 provided inside the main body 1, and the negative potential generating circuit 6 and the potential output pad 60 are electrically connected by a conductive wire 90. 2 and 3, reference numeral 91 is a conductive wire connecting the PTC heater 5 and the main substrate 9, 92 is a conductive wire connecting the temperature sensor 51 and the main substrate 9, and the negative potential generating circuit 6, the PTC heater 5, and the temperature The sensor 51 is connected to the control unit 8 composed of a microcomputer mounted on the main board 9.
[0026]

The cooling surface of the Peltier element 7 is brought into contact with the inner surface of the cap 30B, and the heat radiating fins 70 are connected to the heat radiating surface. Further, a Peltier element temperature sensor 72 and a radiation fin temperature sensor 73 made of a thermistor are disposed inside the cap 30B so as to contact the cap 30B and the radiation fin 70, respectively, and are opposed to the radiation fin 70. A cooling fan 71 is arranged.
[0027]
The Peltier element temperature sensor 72 monitors the temperature of the Peltier element 7 in order to maintain the second contact surface 3B at the set temperature. Further, the heat radiation fin temperature sensor 73 monitors the temperature of the heat radiation fin 70 in order to keep the heat radiation fin 70 at a predetermined temperature. The cooling fan 71 blows air to the radiating fins 70 to radiate heat.
In FIG. 2, 93 is a conductive wire connecting the Peltier element 7 and the main substrate 9, and 94 and 95 are conductive wires connecting the temperature sensors 72 and 73 and the main substrate 9, respectively. , 73 are connected to the control unit 8 on the main board 9.
[0028]
On the main board 9, a sound generation circuit 100 and a speaker 101 for generating and notifying a sound are mounted. When the start / stop switch 40, the level setting switch 41, and the mode selection switch 42 are pressed, the sound generation circuit 100 generates a buzzer sound “pea” from the speaker 101.

Input / output units (shown as blocks in the figure) are connected to the control unit 8 via a bus 84, and the CPU 80 enters the RAM 82 while reading / writing data from / to the RAM 82 in accordance with a program stored in the ROM 81. The operation of each part of the output is controlled in series.
[0030]
FIG. 5 shows the flow of control by the control unit 8, in which “ST” is an abbreviation for “STEP”.
In the figure, when power is supplied from the plug 2, the determination of ST1 is “YES”, and the CPU 80 sets the operation mode and the temperature level to “auto mode” and “high” as initial states (ST2).
[0031]
In the next ST3 to ST5, the operation waits for the operation of the start / stop switch 40, the level setting switch 41, and the mode setting switch 42. When the start / stop switch 40 is pressed in this standby state, the determination in ST3 is “YES” and the process proceeds to ST6, and the CPU 80 confirms the currently set operation mode (ST6). Since it is initially set to “auto mode”, the determination in ST7 is “YES”, and the facial processing by “auto mode” is executed (ST12).
[0032]
When the level setting switch 4 is pressed in the standby state of ST3 to ST5, the determination of ST4 is “YES”, the CPU 80 confirms the currently set level, and sets the temperature level to the next level (for example, “high”). The level is switched to “medium” level (ST16, 17).
[0033]
When the mode selection switch 42 is pressed in the standby state of ST3 to ST5, the determination of ST5 becomes “YES”, the CPU 80 confirms the currently set operation mode, and sets the operation mode to the next operation mode (for example, “Ode” The mode is switched from “mode” to “potential beauty mode” (ST18, 19).
[0034]
When the start / stop switch 40 is pressed after switching the operation mode, the process proceeds from ST3 to ST6 and the current operation mode is confirmed.
If the current mode is “potential beauty mode”, the determination in ST8 is “YES” and the process proceeds to ST13, where the facial beauty processing in “potential beauty mode” is executed.
[0035]
If the current mode is “thermal beauty mode”, the determination in ST9 is “YES” and the process proceeds to ST14, where the facial treatment by “thermal beauty mode” is executed.
If the current mode is the “cooling beauty mode”, the determination in ST10 is “YES” and the process proceeds to ST15, where the facial beauty processing in the “cooling beauty mode” is executed.
If the current mode is “warm / cool beauty mode”, the determination in ST10 is “NO”, the process proceeds to ST11, and the facial treatment in “warm / cool beauty mode” is executed.
[0036]
FIG. 6 shows a flow of the facial beauty processing in the “auto mode”.
First, upon the start of the "automatic mode", upon the CPU80 which to start the internal timer, in order to execute the facial treatment with "negative potential", a negative predetermined potential negative potential generating circuit 6 is generated potential The negative potential is applied to the first contact surface 3A by applying it to the output pad 60 (ST12-1).
[0037]
In the next ST12-2, the CPU 80 checks with the timer whether or not 3 minutes of the set time has elapsed. When 3 minutes have elapsed, the determination in ST12-2 is “YES”, and the CPU 80 operates the sound generation circuit 100 to generate a sound of a predetermined melody for notification (ST12-3) and to the potential output pad 60. The application of the potential is stopped to finish the facial treatment by the negative potential, and then the PTC heater 5 is energized to apply heat to the first contact surface 3A (ST12-4).
[0038]
In the next ST12-5, the CPU 80 confirms whether or not two minutes have passed by using a timer. When the determination is “YES”, the CPU 80 operates the Peltier element 7 to move the second contact surface 3B. Precooling is performed, and at the same time, the cooling fan 71 is operated to blow air to the heat radiation fin 70 (ST12-6).
In the next ST12-7, the CPU 80 confirms whether or not one minute has passed by the timer, and when the determination is “YES”, the CPU 80 operates the sound generation circuit 100 to perform a predetermined melody for notification. Is generated (ST12-8), the energization of the PTC heater 5 is stopped, and the facial treatment by the heat is finished (ST12-9).
[0039]
In the next ST12-10, the CPU 80 checks whether or not another two minutes have passed by using a timer. When the determination is “YES”, the CPU 80 operates the sound generation circuit 100 to perform a predetermined melody for notification. (ST12-11), the energization to the Peltier element 7 is stopped, the cooling of the second contact surface 3B is stopped, and the facial treatment process by cooling is finished (ST12-12).
At this time, the cooling fan 71 continues to blow air, and when three minutes have passed, the determination in ST12-13 becomes “YES”, and the CPU 80 stops the blowing operation by the cooling fan 71 (ST12-14). .
[0040]
