  Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS. In the following description, when referring to “front-rear direction”, “left-right direction”, and “up-down direction”, a user who wears a beauty instrument for eyes and faces forward as shown in FIG. 1 is used as a reference. The “front-rear direction”, “left-right direction”, and “up-down direction” are used. The front-rear direction is the direction closer to the user.

  As shown in FIG. 1 to FIG. 6, a beauty instrument for eyes (hereinafter sometimes abbreviated as “instrument”) 1 of this embodiment includes a pad 21 made of an elastic material that comes into contact with the eyes of the user when worn, A housing 12 constituting an outer shell made of a rigid material to which the pad 21 is attached and a cover 11 are provided.

  As shown in FIG. 1, the wearable band 20 attached to both the left and right sides of the housing 12 is put on the back of the user's occipital region so that the eye and the periphery of the eye can be covered.

  As shown in FIGS. 4, 8, and 9, a symmetrical recess 15 is formed on the user's eye side of the housing 12, and the pad 21 covers the upper side and both left and right sides of the recess 15. Is detachably attached to the housing 12. In the state where the appliance 1 is mounted as shown in FIG. 1, the upper and left and right sides of the user's eyes are covered with the pads 21.

  As shown in FIGS. 4 and 6, the concave portion 15 faces the user's eyes when the instrument 1 is mounted, and is narrowed and formed symmetrically at the center position corresponding to the user's nose bridge. ing.

  When the appliance 1 is mounted, if the contact surface 22 which is the upper peripheral portion of the pad 21 and the peripheral portions on both the left and right sides of the user's eyes comes into contact with the skin around the user's eyes, the housing 12 The opening edge of the recess 15 is extended by the pad 21. A space S of a substantially closed space that is connected to the outside via a gap only at a position corresponding to the nasal bridge (below the eyes) between the inner surface of the recess 15 and the contact surface 22 of the pad 21 and the eyes of the user. (Refer to FIG. 6) is formed.

  The planar shape of the contact surface 22 of the pad 21 as viewed from above is a shape obtained by reducing the average shape around the forehead of many men and women in a similar manner so as to correspond to women. The material of the pad 21 is made of silicon rubber in consideration of the fit to the face, ease of attachment / detachment, ease of cleaning when it becomes dirty, and durability. The thickness of the contact surface 22 is approximately 1 mm or less, and is thinner than the mounting surface 23 to the housing 12 formed inside the contact surface 22 as shown in FIG.

  The mounting surface 23 of the pad 21 is provided with a plurality of protrusions 24 formed in an outer peripheral shape that is slightly larger than the mounting hole 14 provided in the outer edge portion of the housing 12. When elastically fitted, the pad 21 is attached to the housing 12. Further, the pad 21 can be removed from the housing 12 by removing the protrusion 24 from the mounting hole 14.

  Hooks 13 are formed on the left and right ends of the housing 12 respectively. And the edge part of the said mounting | wearing bands 20, such as a rubber band, is attached to the hook part 13 as needed. That is, as shown in FIG. 1, the instrument 1 does not fall from the eye by hanging the mounting band 20 on the back of the head with the pad 21 of the instrument 1 in contact with the eye. Therefore, the wearing band 20 functions as a fixing member for fixing the pad 21 in a state of being in contact with the user's eyes.

In addition, the wearing band 20 is not necessarily required if the pad 21 of the instrument 1 is brought into contact with the eyes from above with the user lying on his back.
The left and right side portions of the cover 11 extend so as to cover the hook portion 13 of the housing 12 so that the hook portion 13 is not exposed during use. 2 to 6, illustration of the wearing band 20 is omitted.

As shown in FIG. 4, a water supply plate 30 having an outer edge shape similar to the peripheral shape of the recess 15 is detachably fitted in the inner portion of the recess 15 of the housing 12.
As shown in FIG. 2, the upper surface of the cover 11 is formed of a colored transparent synthetic resin, and the planar shape thereof is substantially a crescent shape. An operation unit and a display unit are configured on the upper surface of the cover 11, and a pair of left and right switches 50 are formed.

  The switch 50 is attached so that its upper end does not protrude from the upper surface of the cover 11, and the switch 50 is not erroneously operated even when the instrument 1 is placed on a desk in an upside down direction. .

  As shown in FIG. 5, in the cover 11, a control board 51 held by the housing 12 is disposed below the upper surface of the cover 11, and the control circuit and the operation of the instrument 1 are arranged on the control board. An LED that lights up depending on the state is mounted. The lighting state of the LED is recognized by light transmitted through the upper surface of the cover 11.

  A sheet-like heater 40 is provided on the rear side of the recess 15 of the housing 12, and is in contact with the heating surface 16 of the housing 12 positioned between the heater 40 and the recess 15. A pair of left and right heat transfer plates 41 made of an aluminum plate are in contact with the rear surface of the heater 40. Each of the heat transfer plates 41 transmits heat generated by the heater 40 to the skin contact surface 17 of the housing 12 shown in FIGS. The skin contact surface 17 is formed symmetrically in the left-right direction below the recess 15 of the housing 12.

  Further, as shown in FIG. 15, the heat transfer plate 41 is provided with a temperature sensor 42 for indirectly detecting the temperature of the heater 40, and a detection signal of the temperature sensor 42 is output to the control circuit. The control circuit controls the current supplied to the heater 40 so that the temperature of the heater 40 does not exceed a preset temperature.

  A battery case 52 is provided on the control board 51, and a rechargeable battery 53 is held in the battery case 52. The control circuit and heater 40 operate using the battery 53 as a power source.

  As shown in FIGS. 5 and 9, a vibration motor 54 is provided inside the skin contact surface 17 of the housing 12. The operation of the vibration motor 54 is controlled by the control circuit, and the vibration is generated by the rotation of the eccentric weight 54a attached to the output shaft, and the vibration is transmitted to the skin contact surface 17.

  As shown in FIG. 8, a jack insertion port 29 is provided in the rear lower portion of the housing 12, and the battery 53 can be charged by inserting the jack 56 of the AC adapter as shown in FIG. The jack insertion port 29 is exposed obliquely downward while the instrument 1 is placed on a horizontal plane. Therefore, even when water is applied from above with the appliance 1 standing still, or when the water dripping from the water supply plate 30 is transferred to the lower surface of the housing 12, the water easily enters the jack insertion port 29. It is designed not to enter.

  Legs 28 are provided on the left and right sides of the lower surface of the cover 11 so that when the instrument 1 is placed on a desk, a load is not applied to the jack 56 inserted into the jack insertion port 29.

  In addition, since the heavy battery 53 is located at the rear part (left side in FIG. 8) of the housing 12 and the center of gravity of the housing 12 is located behind the center part in the front-rear direction, the housing 12 falls when the instrument 1 falls. The rear side of the housing 12 automatically becomes the lower side, and the concave portion 15 of the housing 12 faces upward. Therefore, the water dripping from the water supply plate 30 is unlikely to spill from the recess 15.

  Next, a mist generator will be described. As shown in FIGS. 4, 5, 8, and 9, the mist generating apparatus includes the heater 40 that functions as a heating unit and the water supply plate 30 that functions as a mist generating unit.

  The water supply plate 30 is formed of a synthetic resin (for example, polycarbonate, polybutylene terephthalate) having heat resistance and steam resistance, and has a large number of small through holes 32 that can hold the liquid by surface tension. The through hole 32 is penetrated in the thickness direction of the water supply plate 30.

  The liquid held in the water supply plate 30 is water (water whose main component is tap water, distilled water, ion-exchanged water, etc.), or water containing a beauty agent (skin water, cosmetic liquid, etc.) )

  As shown in FIG. 4, when the device 1 is mounted on the face, a large number of through holes 32 are located in a region facing the user's eyes, and the through holes are located at a position facing the nasal bridge between both eyes. 32 is not provided. In addition, you may provide the through-hole 32 sparsely in this part.

  The diameter of the through-hole 32 is equal to or greater than the diameter of the heat receiving surface 30 b on which the diameter of the facing surface 30 a side with respect to the eyes of the water supply plate 30 is overheated by the heater 40. The diameter of each through-hole 32 is preferably about 0.5 mm to 1.5 mm in order to ensure sufficient surface tension.

  Behind the water supply plate 30, the heating surface 16 of the housing 12 is heated by the heater 40, and the water supply plate 30 in contact with the heating surface 16 is heated to heat the water held in each through hole 32. Is done. Then, the water held in the through-hole 32 is discharged as a warm mist into the recess 15 and supplied to the user's eyes. Therefore, the opposing surface 30a of the water supply plate 30 functions as a mist discharge part that discharges mist toward the user's eyes. With such a configuration, it is preferable that the water supply plate 30 is closely attached to the heating surface 16.

  As shown in FIGS. 4, 8, and 13, a pair of convex portions 18 a are formed on the ceiling surface of the concave portion 15 of the housing 12 in the left-right direction at a position separated from the heating surface 16 by the plate thickness of the water supply plate 30. Is provided. In addition, the housing 12 is provided with a convex portion 18b that engages hooks on both sides of the grip portion 31 provided at the central portion in the left-right direction of the water supply plate 30 below the convex portion 18a.

When the water supply plate 30 is engaged with the convex portions 18 a and 18 b, the water supply plate 30 is held in close contact with the heating surface 16.
At this time, when the water supply plate 30 is engaged with the convex portions 18a and 18b in a state where the water supply plate 30 is bent so as to be convex toward the heating surface 16, the portion with many through holes 32 is heated. The mist generation is promoted.

  As shown in FIG. 8, the grip portion 31 of the water supply plate 30 extends forward so as to be away from the heating surface 16. Further, the central portion in the left-right direction of the water supply plate 30 is narrow in the vertical direction, and a hole 30c is formed so as to further reduce the surface area. Therefore, heat is not easily transmitted to the grip portion 31, and water is not easily transmitted to the grip portion 31.

  Note that the amount of water held in all the through holes 32 of the water supply plate 30 is an amount that can generate mist necessary for one use of the instrument 1. That is, after using the appliance 1 once, almost no water is left in the water supply plate 30, and the slightly remaining water can be dried only by the residual heat of the heating surface 16 so as to suppress generation of germs and mold. Yes.

  The heater 40 is formed so that the amount of heat generated is high at positions corresponding to the left and right sides of the water supply plate 30 in order to efficiently generate mist in the vicinity of the left and right eyes. Specifically, as shown in FIG. 16, a heating wire 36 that converts current into heat is printed on one surface of a base material 35 formed of a sheet-like insulator.

  The outer shape of the base material 35 is similar to the outer shape of the water supply plate 30, and both side portions thereof are substantially the same as the shape of a portion (mist generating portion) in which many through holes 32 of the water supply plate 30 are formed. The intermediate part is narrower than both side parts.

  The heating wire 36 is printed over almost the entire length of the base material 35, and meandering portions 37a and 37b meandering several times are formed on both sides of the base material 35, so that a sufficient length is secured. Yes. Moreover, the line width of the heating wire 36 of the meandering parts 37a and 37b is narrower than the line width of the heating wire 36 of the connection part 38 which connects both meandering parts 37a and 37b.

  Further, the cross-sectional area of the heating wire 36 of the meandering portions 37 a and 37 b is formed to be smaller than the cross-sectional area of the heating wire 36 of the connection portion 38. With such a configuration, the electrical resistance value per unit length of the heating wire 36 of the meandering portions 37 a and 37 b is higher than the electrical resistance value per unit length of the heating wire 36 of the connection portion 38. Then, both ends of the heating wire 36 are electrically connected to the control circuit via a power supply line.

  With such a configuration, when the heating wire 36 is energized from the control circuit, the heating wire 36 generates heat. The heating wires 36 of the meandering portions 37 a and 37 b generate heat at a higher temperature than the heating wire 36 of the connecting portion 38, and the heat generation amount per unit area of both side portions of the base material 35 is the unit area of the intermediate portion of the base material 35. The amount of heat generated per hit is larger, and heat at a high temperature can be transmitted to both side portions of the water supply plate 30.

  In addition to the above, as a means for suppressing the amount of heat generated at the intermediate portion in the left-right direction of the heater 40, a heat sink is provided at the intermediate portion in the left-right direction of the heater 40. It is conceivable to connect with electrical materials.

  As means for suppressing the temperature of the intermediate portion in the left-right direction of the water supply plate 30, increasing the thickness of the housing 12 constituting the heating surface 16 with the water supply plate 30 at the intermediate portion in the left-right direction of the heater 40, It is conceivable to provide a gap between the intermediate portion in the left-right direction and the heating surface 16.

With the above configuration, even if the upper part of the user's nasal bridge is closer to the water supply plate 30 than the eyes, the temperature felt at the upper part of the nasal bridge is suppressed so as not to exceed the temperature felt by the eyes.
Next, a heat application device that applies heat to the eyes will be described.

  The heat transfer plate 41 is disposed on the rear surface of the heater 40 so as to be in close contact with the heater 40. As shown in FIGS. 5 and 14, a heater cover 49 attached to the housing 12 is disposed behind the heat transfer plate 41 and protrudes from the heater cover 49 toward the heat transfer plate 41. A large number of protrusions 61 are formed. Then, the heat transfer plate 41 is pressed toward the heater 40 by the protrusion 61 so as to come into close contact therewith.

  The tip of the projection 61 is rounded into a hemispherical shape, while ensuring sufficient strength to press the heat transfer plate 41 sufficiently, the contact area with the heat transfer plate 41 is reduced to reduce the heat conduction to the heater cover 49. It is supposed to be.

  The heat transfer plate 41 is bent in the horizontal direction along the lower surface of the recess 15 below the portion in close contact with the heater 40 and extends to the vicinity of the skin contact surface 17 of the housing 12 without contacting the housing 12. Further, five divided flat plates 43a and 43b are formed extending downward in a comb-teeth shape along the skin contact surface 17.

  The skin contact surface 17 of the housing 12 is a curved surface convex toward the front, that is, the face side, and the shape of the back surface of the skin contact surface 17 is a concave curved surface corresponding to the curved surface. For this reason, in order to give followability so that heat exchanger plate 41 may adhere to the back of skin contact surface 17, five division flat plates 43a and 43b constitute a part of convex curved surface along a concave curved surface. It is formed to do.

  The divided flat plates 43a and 43b are formed such that their lengths are sequentially reduced from the one located in the center toward the side. The number of the divided flat plates 43a, 43b is not limited to five, and may be about 3-10.

To the divided flat plates 43 a and 43 b of the heat transfer plate 41, grease having excellent thermal conductivity is applied in order to ensure adhesion with the back surface of the skin contact surface 17 of the housing 12.
As shown in FIG. 14, the heater cover 49 is formed with a protrusion 62 that presses the divided flat plates 43 a and 43 b toward the back surface of the skin contact surface 17. Then, each of the divided flat plates 43a and 43b is pressed by the protrusion 62 so as to follow and adhere to the back surface of the skin contact surface 17.

The shape of the protrusion 62 is the same as that of the protrusion 61 that presses the heat transfer plate 41 toward the heater 40.
Of the divided flat plates 43a and 43b, an elongated hole 45 is formed in the vicinity of the base end portion of the divided flat plate 43b located on the center side in the left-right direction of the housing 12 in a direction along the bent edge of the divided flat plate 43b. Yes. The long hole 45 is formed as a temperature smoothing means that aligns the heat conduction distance from the heater 40 to each of the divided flat plates 43a and 43b and aligns the temperatures of the divided flat plates 43a and 43b.

With such a configuration, the temperature of the divided flat plate 43a is set to be equal to or higher than the temperature of the other divided flat plate 43b.
The temperature sensor 42 is attached to the center in the vertical direction on the rear surface of the divided flat plate 43a located at the center. That is, since the skin contact surface 17 is in a position below the central portion in the vertical direction and contacts the cheek portion below the orbit, the temperature sensor 42 is disposed at a position corresponding to the cheek portion.

  Further, since the skin contact surface 17 is curved, the skin contact surface 17 at a position corresponding to the divided flat plate 43a is the heat application position where the pressing force is most applied to the skin surface, and the temperature is easily transmitted. In addition, since the divided flat plate 43a has a temperature equal to or higher than that of the divided flat plate 43b, the heat of the divided flat plate 43a is most likely to raise the skin surface temperature via the skin contact surface 17. For this reason, the temperature sensor 42 is attached to the divided flat plate 43a.

  Furthermore, since the vertical position and width of the recess 15 of the housing 12 and the vertical position and width of the skin contact surface 17 are designed based on the average size of the eye socket, the skin contact surface The upper ridge part of 17 hardly contacts the skin surface. Even in the case of contact, since the pressing force does not act so much, heat conduction is small.

  Further, since the heat transfer plate 41 is not in contact with the housing 12 except for the divided flat plates 43a and 43b, heat in the vicinity of the portion in contact with the heater 40 is not transmitted to the skin surface through the housing 12. Therefore, since excessive heat is not transmitted to the skin surface, safety is high.

  As shown in FIG. 15, the temperature sensor 42 is fixed by bending a claw 44 while being positioned in a vertical direction by a convex portion 46 provided on the divided flat plate 43 a. And since the convex part 46 and the nail | claw 44 are formed by processing the division | segmentation flat plate 43a, compared with the case where the temperature sensor 42 is fixed using components other than the division | segmentation flat plate 43a, heat conduction loss is low. It becomes possible to suppress.

  In addition to the above, the means for fixing the temperature sensor 42 to the divided flat plate 43a is to press and fix the temperature sensor 42 with a protrusion protruding from the heater cover 49, and between the heater cover 49 and the temperature sensor 42, rubber or It is conceivable to sandwich and fix an elastic body such as a sponge. However, since these increase the heat conduction loss, it is necessary to take measures as necessary.

  The plate thickness of the heat transfer plate 41 is selected in accordance with the output performance of the heater 40, but is 0.3 mm in this embodiment. It is desirable to study in the range of about 0.2 to 2.0 mm depending on the power supplied to the heater 40.

  That is, the heat transfer plate 41 needs to quickly transfer the heat of the heater 40 to the skin surface via the skin contact surface 17. If the thickness of the heat transfer plate 41 is insufficient, the heat capacity of the heat transfer plate 41 becomes small and it becomes difficult to maintain the temperature.

  On the other hand, when the thickness of the heat transfer plate 41 becomes excessive, the heat capacity of the heat transfer plate 41 increases, and heat is hardly transferred to the divided flat plates 43a and 43b, and the temperature of the divided flat plate 43a exceeds the upper limit. Even if energization of the heater 40 is stopped, the temperature overshoot is large, so the temperature does not drop quickly, and a comfortable temperature cannot be stably supplied to the skin surface.

  Therefore, when an optimum plate thickness is selected within the range of plate thicknesses as described above, an optimum temperature can be transmitted from the heater 40 to the skin contact surface 17 via the heat transfer plate 41 and to the water supply plate 30. It becomes possible to generate heat mist by supplying heat.

Next, a vibration applying device that applies vibration to the skin surface will be described.
As shown in FIGS. 5, 6, and 9, in the vibration applying device, the vibration motor 54 is operated by a control current supplied from a control circuit on the control board 51 to generate vibration. The vibration motor 54 is fixed to the heater cover 49 behind the skin contact surface 17.

  Specifically, like the heat transfer plate 41, the heater cover 49 has a shape bent in a cross-sectional crank shape in the vertical direction, and is spaced from the heat transfer plate 41 at a certain distance behind the heat transfer plate 41. Are disposed at a distance from each other.

  The vibration motor 54 is held in the axial direction and the radial direction of the output shaft of the motor by ribs protruding from the heater cover 49. Further, when the rib is protruded from the motor cover 55 so as to face the rib of the heater cover 49 and the motor cover 55 is sandwiched between the heater cover 49 and the vibration motor 54, the motor cover 55 is fixed to the heater cover 49 with screws. The vibration motor 54 is fixed while being sandwiched between the motor cover 55 and the heater cover 49.

  With such a configuration, since the vibration motor 54 is fixed between the motor cover 55 and the heater cover 49 without using an elastic buffer material such as rubber, vibration generated by the vibration motor 54 is not significantly attenuated. It is transmitted to the heater cover 49. Then, the vibration of the heater cover 49 is transmitted to the skin contact surface 17 of the housing 12.

  Since the heater cover 49 is formed with ribs for holding the vibration motor 54 in the horizontal portion which is an intermediate portion in the vertical direction, the rigidity is increased and vibration of the vibration motor 54 is easily transmitted.

  The heater cover 49 covers and heat-insulates the rear of the heat transfer plate 41. Ribs 63 are formed on the housing 12 at positions along the outer shapes of the heater 40 and the heat transfer plate 41 toward the rear.

  Then, the heater cover 49 is fixed to the housing 12 with the heater cover 49 in contact with the leading edge of the rib 63, and the housing 12 and the heater cover 49 close the heater 40 and the heat transfer plate 41. A space C is formed.

  Further, as shown in FIG. 5, a plurality of stepped portions 64 are formed at the leading edge of the rib 63, and a positioning convex portion 65 that fits the rib 63 is formed at the peripheral portion of the heater cover 49. . And if the heater cover 49 is fixed to the housing 12 while engaging the positioning convex part 65 with the step part 64 and positioning in the front-back direction, the up-down direction, and the left-right direction, the airtightness of the closed space C will improve.

  The divided flat plates 43a and 43b are coated with grease in order to improve thermal conductivity. This grease generally contains silicon, and silicon volatilized by heat may adhere to the electrical contact portion and cause contact failure.

  However, in this embodiment, since the portion to which the grease is applied is in the closed space C, the volatilized silicon does not adversely affect the vibration motor 54, the control circuit, and the like located outside the closed space C. .

  The rotation speed of the vibration motor 54 is controlled by a microcomputer signal on the control circuit. A plurality of modes in which a plurality of vibration patterns are combined are set, and the mode can be switched every time the switch 50 is pressed.

Next, the control part of a mist generator, a heat | fever provision apparatus, and a vibration provision apparatus is demonstrated.
The control unit includes a battery case 52 accommodated between the housing 12 and the cover 11, a battery 53 set in the battery case 52, and a control board 51 provided above the battery case 52 as main parts. ing.

  The battery 53 is a rechargeable storage battery, and can be charged by inserting an AC adapter (not shown) through a jack 56 into a jack insertion port 29 provided in the housing 12.

  The control circuit controls the operation of the heater 40 and the vibration motor 54 based on the power supplied from the battery 53. Based on the pressing operation of the switch 50 and the temperature detection signal output from the temperature sensor 42, the number of rotations of the vibration motor 54 is controlled and the switch interposed between the heater 40 is opened and closed. The heating operation of the heater 40 is controlled.

  The control circuit controls the current supplied to the heater 40 based on the temperature detection signal output from the temperature sensor 42 attached to each of the heat transfer plates 41. That is, the supply of current to the heater 40 is stopped when at least one of the temperature sensors 42 detects a temperature equal to or higher than a preset first set temperature.

  The heat transfer plate 41 interposed between the heater 40 and the skin contact surface 17 does not immediately drop in temperature due to the remaining heat of the heater 40 even after the supply of current to the heater 40 is stopped. Thereafter, when the temperature sensor 42 detects a second set temperature that is equal to or lower than the first set temperature, the control circuit restarts energization of the heater 40 and repeats such an operation, whereby the heat transfer plate 41 The temperature is maintained within a predetermined temperature range.

Further, as the temperature approaches the first set temperature, the supply current can be gradually decreased to suppress the overshoot of the temperature of the heat transfer plate 41.
You may make it prevent the overheating of the heat exchanger plate 41 by accumulation | storage of an overshoot by changing 1st and 2nd preset temperature for every use elapsed time. Such an operation makes it possible to continue to supply a comfortable temperature from the skin contact surface 17 to the skin surface.

Next, the operation of the cosmetic device for eyes constructed as described above will be described.
When using the eye beauty instrument 1, as shown in FIG. 1, the instrument 1 is mounted so that the eye is covered with a pad 21. When the wearing band 20 is not used, as shown in FIG. 6, the face 21 is brought into contact with the contact surface 22 of the pad 21 from the forehead to the temple, and the skin contact surface 17 of the housing 12 is in contact with the cheek. Is held so that it does not deviate from the eyes.

  The pad 21 is made of an elastic material such as silicon rubber, and the thickness of the contact surface 22 is about 1 mm or less, which is smaller than the thickness (about 2 mm) of the mounting surface 23 to the housing 12. Easy to deform. For this reason, even if a user's face is large, if the instrument 1 is put on the face and turned up, the contact surface 22 of the pad 21 spreads outside by the dead weight of the instrument 1 and adheres to the face.

It is also possible to secure adhesion by preparing a plurality of pads (for example, S, M, and L sizes) having different sizes and making the pads replaceable according to the size of the user's face. .
If the face is extremely large or small and the weight of the device 1 does not provide sufficient contact, the wearing band 20 is used to bring the contact surface 22 of the pad 21 into close contact with the face.

  Since the hook portion 13 for attaching the mounting band 20 is covered with the cover 11, even if the instrument 1 is accidentally dropped or placed in various directions, a load that directly acts on the hook portion 13 is applied. Since it is reduced, it is possible to prevent inadvertent damage.

  Further, since the outer edge portion of the pad 21 and the fitting portion between the housing 12 and the pad 21 are almost covered by the cover 11, even when placed in various directions, an unnecessary load acts on these portions. Can be prevented. Therefore, even when left for a long time, the deformation of the pad 21 can be prevented.

  In use, when the switch 50 is pressed and turned on, the control circuit operates to start energization of the heater 40. Then, the heater 40 generates heat and the temperature of the heating surface 16 of the housing 12 rises, and the water held in the through hole 32 of the water supply plate 30 is heated by the heat.

  Then, water is vaporized to generate a warm mist, and the warm mist is discharged from the facing surface 30a of the water supply plate 30 to the space S in the recess 15. At this time, since the through holes 32 holding water are intensively formed on the water supply plate 30 at portions facing the eyes, the warm mist is supplied intensively to the user's eyes.

  Moreover, if the diameter of the through-hole 32 becomes large toward the opposing surface 30a of the water supply plate 30, since the heat exchange area in the through-hole 32 will become wide toward the opposing surface 30a, vaporization efficiency will rise. As a result, it is possible to shorten the time from when the heater 40 generates heat until the warm mist is generated.

  The high-temperature warm mist discharged from the through-hole 32 floats in the space S that is substantially closed, and moves toward the user's eyes while lowering the temperature. Therefore, high temperature warm mist is not sprayed directly on the skin of the eyes.

  The warm mist that has moved to the eyes adheres to the skin of the eyes. Then, since the skin of the eye is moisturized with a warm mist at an appropriate temperature, humidification and moisturization of the skin of the eye, suppression of drying, improvement of fineness of the texture, and recovery from fatigue by promoting blood circulation can be achieved.

  The control circuit has a mist temperature in the range of 35 ° C. to 45 ° C. (desirably 39 ° C. to 44 ° C.) and a mist amount of 10 mg to 100 mg / min (desirably 10 mg to 60 mg / min) in order to generate an appropriate mist. The temperature of the heater 40 is controlled so as to fall within the range.

  In order to save power and avoid low-frequency burns, energization of the heater 40 is interrupted by control circuit control when a predetermined time (12 minutes as an example in the present embodiment) elapses from the start of energization.

  When the heater 40 generates heat, the heat transfer plate 41 in close contact with the rear surface of the heater 40 is heated, and the heat from the divided flat plates 43a and 43b below the heat transfer plate 41 passes through the skin contact surface 17 of the housing 12 to the eye. It is transmitted to the skin of the lower part. The heat transfer plate 41 is not in contact with the upper and lower portions except for the heater 40 and the skin contact surface 17 of the housing 12, and is disposed in a closed space C surrounded by the housing 12 and the heater cover 49. Therefore, useless heat dissipation is prevented, and the heat generated by the heater 40 is efficiently transmitted from the heater 40 to the skin contact surface 17 via the heat transfer plate 41.

  The temperature of the heat transfer plate 41 is managed by the temperature sensor 42 in the divided flat plate 43a portion, and the temperature transmitted to the skin contact surface 17 is maintained at an appropriate temperature by the thickness of the heat transfer plate 41, the shape of the long holes 45, and the like. However, the required temperature is controlled to be supplied to the water supply plate 30. Accordingly, the temperature transmitted from the heater 40 to the skin contact surface 17 and the temperature transmitted from the heater 40 to the water supply plate 30 are collectively controlled based on the detection signal of the temperature sensor 42.

  Simultaneously with energization of the heater 40, energization of the vibration motor 54 is started. Then, the vibration generated by the vibration motor 54 is transmitted to the heater cover 49, and is transmitted from the protrusion 62 of the heater cover 49 to the skin contact surface 17 of the housing 12 through the divided flat plates 43a and 43b. The vibration of the vibration motor 54 is transmitted from the outer edge of the heater cover 49 to the skin contact surface 17 through the rib 63 of the housing 12, and the vibration is efficiently transmitted to the skin contact surface 17 through such a transmission path. Is done.

  The skin contact surface 17 is not made of a soft material such as cloth or rubber, but is formed of a hard material and directly pressed against the skin. Therefore, the vibration generated by the vibration motor 54 is not greatly attenuated, but the skin contact surface. 17 is transmitted.

Further, since the pad 21 is in contact with the face so as to surround the recess 15 above and on the side of the recess 15, the skin contact surface 17 is not displaced from the skin surface due to vibration of the housing 12.
Due to the vibration of the skin contact surface 17, an appropriate massage effect is obtained for the user's eyes, which contributes to blood circulation promotion of the eyes. In particular, the effect of eliminating the bear is great because the vibration is transmitted to the skin under the eyes where the bear can easily form.

According to the present embodiment, the following effects can be obtained.
(1) The warm mist generated by the mist generating device, the heat generated by the heat applying device, and the vibration generated by the vibration applying device can moisturize the eyes and give appropriate heat and massage. Therefore, it is possible to promote blood circulation in the eyes and eliminate eye strain and bears under the eyes.
(2) The skin contact surface from the heater 40 by adjusting the thickness and shape of the heat transfer plate 41, the shape, number and position of the long holes 45, etc., and adjusting the heating wire shape and arrangement of the heater 40.

(3) Heat generated by the heater 40 can be transmitted to the skin contact surface 17 by the heat transfer plate 41.
(4) The divided flat plates 43a and 43b formed on the heat transfer plate 41 can be surely followed and brought into contact with the skin contact surface 17. Therefore, heat can be efficiently transferred from the heat transfer plate 41 to the skin contact surface 17.
(5) The comb-shaped divided flat plates 43a and 43b can be brought into contact with the back surface of the skin contact surface 17 which is a concave curved surface while being flat. Since the divided flat plates 43a and 43b can be easily formed by cutting and bending the heat transfer plate 41 formed of an aluminum plate into a comb shape, the manufacturing cost of the heat transfer plate 41 can be reduced.
(6) Since the temperature sensor 42 is attached to the divided flat plate 43a that is in contact with the back surface of the portion of the skin contact surface 17 that is most strongly pressed against the skin surface, the temperature of the heat transmitted to the skin surface is easily detected. be able to. Accordingly, it is possible to generate a warm mist at a comfortable temperature and to warm the skin surface at a comfortable temperature.
(7) Since the temperature sensor 42 is attached to the divided flat plate 43a, the temperature of which is not lower than the other divided flat plates, among the divided flat plates 43a and 43b, the highest temperature transmitted to the skin contact surface 17 is detected. Can do. Therefore, safety can be improved.
(8) The transmission rate and the transmission temperature of the heat transmitted to the divided flat plates 43a and 43b can be controlled by the long holes 45 provided in the heat transfer plate 41. Therefore, without requiring a member other than the heat transfer plate 41, the temperature of the divided flat plate 43a to which the temperature sensor 42 is attached can be adjusted to be higher than the temperature of the other divided flat plate 43b.
(9) In the heater 40, since the heat generation amount of the heating wire 36 is increased on both sides corresponding to the mist generating part of the water supply plate 30, the water mist can be efficiently generated in the water supply plate 30.
(10) In the heater 40, the amount of heat generated in the portion corresponding to the left and right eyes is suppressed as compared with the amount of heat generated in the portion corresponding to the mist generating portion. It is possible to prevent a high temperature supply and ensure a comfortable feeling of use and safety.
(11) If the heat transfer plate 41 in contact with the heater 40 is constituted by a single plate continuous across the left and right sides of the heater 40, the temperature of the heater 40 is averaged over the entire length in the left-right direction. In the embodiment, the heat transfer plate 41 is divided into two parts on the left and right sides, so that it is possible to prevent a temperature rise in the intermediate portion in the left and right direction of the heater 40 via the heat transfer plate 41. Heat can be efficiently transferred from both sides of the heater 40 to the mist generating portions on both sides of the water supply plate 30, and heat can be applied to the skin contact surface 17 from both sides of the heater 40 via the heat transfer plate 41. It can be transmitted efficiently.
(12) The skin contact surface 17 provided in the hard material housing 12 is brought into contact with the skin surface below the eye, and the eye is covered with a soft material pad 21 attached to the housing 12 on the side and upper side of the eye.

Therefore, the leak from the space S of the warm mist supplied into the space S from the water supply plate 30 as a mist generating device can be suppressed, and the humidification effect and the thermal effect on the skin of the eyes can be improved.
(13) Since the skin contact surface 17 formed on the hard material housing 12 is brought into direct contact with the skin surface under the eye and the skin contact surface 17 is vibrated by the vibration motor 54, the skin surface under the eye Vibrations can be efficiently transmitted to the.
(14) The heater 40 and the heat transfer plate 41 that transmits the heat generated by the heater 40 to the skin contact surface 17 are accommodated in the closed space C covered with the housing 12 and the heater cover 49. Since the vibration motor 54 is attached to the heater cover 49 outside the closed space C so that the heater cover 49 serves as a partition wall, the overheating of the vibration motor 54 due to the heat of the heater 40 can be prevented. Therefore, the reliability of the vibration motor 54 can be improved.
(15) Since the sheet-like heater 40 is brought into contact with only the heat transfer plate 41, the back surface of the skin contact surface 17, and the heating surface 16 to heat the water supply plate 30, the heat generated by the heater 40 is The skin contact surface 17 and the water supply plate 30 can be efficiently transmitted.
(16) Since the vibration motor 54 and the control board 51 are attached to the outside of the closed space C, the silicon volatilized from the heat conduction grease applied between the heat transfer plate 41 and the back surface of the skin contact surface 17 vibrates. The motor 54 and the control circuit are not adversely affected.
(17) Since the heat transfer plate 41 is pressed against the heater 40 by the projection 61 protruding from the heater cover 49, the heat generated by the heater 40 can be efficiently transmitted to the heat transfer plate 41.

Can communicate well.
(19) The vibration transmitted from the vibration motor 54 to the heater cover 49 can be efficiently transmitted to the skin contact surface 17 of the housing 12 through the protrusion 62.
(20) Since the tips of the projections 61 and 62 are hemispherical, the contact area between the tips of the projections 61 and 62 and the heat transfer plate 41 is reduced, and heat conduction from the heat transfer plate 41 to the heater cover 49 is suppressed. However, a sufficient pressing force for pressing the heat transfer plate 41 against the heater 40 and the back surface of the skin contact surface 17 can be generated.
