Detailed Description

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

(embodiment mode 1)

Fig. 1 and 2 are perspective views of a beauty appliance 1 according to embodiment 1 of the present disclosure. Fig. 3 and 4 are a side view and a cross-sectional view of the beauty treatment apparatus 1 according to the present embodiment, respectively.

In the present embodiment, as shown in fig. 3 to 5, a direction substantially parallel to the long side portion 10a of the main body portion 10 is defined as an X direction. The thickness direction of the main body 10 is defined as the Z direction. The Y direction is defined as a direction orthogonal to the X direction and the Z direction.

The cosmetic device 1 is a device in which a user holds the main body 10, presses the massage unit 20 against the skin, and moves the massage unit 20 over the skin to apply physical stimulation to the skin.

As shown in fig. 4, the beauty appliance 1 includes a flat main body 10 having a space S1 therein and a massage unit 20 provided at an end 10e of the main body 10 when viewed from the Z direction. At least one protrusion is provided on the outer peripheral edge 20a of the massage part 20.

In the present embodiment, three convex portions (convex

portions

22, 23, 24) are provided on the outer peripheral edge 20 a. However, one or two protrusions may be provided on the outer peripheral edge 20a, or four or more protrusions may be provided.

As shown in fig. 3, the main body 10 includes a long side portion 10a that forms an outer peripheral edge of the cosmetic device 1 when viewed in the Z direction, and a short side portion 10b that faces the massage unit 20.

The main body portion 10 includes a first chamfered portion 10c and a second chamfered portion 10 d. The first beveled edge portion 10c connects one end of the long edge portion 10a and one end of the short edge portion 10b, and faces the massage portion 20. The second beveled portion 10d connects the other end of the long side portion 10a and the other end of the short side portion 10b, and forms an outer peripheral edge of the beauty appliance 1.

The main body portion 10 is substantially trapezoidal in shape when viewed from the Z direction, based on the long side portion 10a, the short side portion 10b, the first bevel side portion 10c, and the second bevel side portion 10 d. The main body 10 functions as a grip for a user to grip when the cosmetic device 1 is used.

When the user holds the main body portion 10 and presses the massage portion 20 against the skin of the user or the skin of a person to be treated other than the user and moves the massage portion 20, physical stimulation is applied to the skin of the user or the person to be treated.

The main body 10 includes a flat main body case 11. The body housing 11 forms the outer contour of the body portion 10.

When the outer surface 11a of the main body case 11 is formed with a corner, the corner may hit the hand of the user holding the main body portion 10 and may give an excessive stimulus to the hand of the user. To prevent this, in the present embodiment, the main body case 11 is formed in such a manner as to be rounded integrally with the outer surface 11 a.

The main body case 11 is formed by joining a plurality of members made of synthetic resin, for example. As shown in fig. 4, a space S1 is formed inside the main body case 11. Circuit board 80, battery 90, and the like are disposed in space S1.

An opening 11e is formed in a surface 11c of the main body case 11. Opening 11e is provided with insertion port 91 into which a connector (not shown) for charging battery 90 is inserted. The opening 11e is covered with a detachable lid 12.

The massage unit 20 includes a massage unit housing 21 having a space S2 therein and forming an outer contour of the massage unit 20. As shown in fig. 3, the massage part case 21 is provided so as to face the short side part 10b and the first bevel side part 10c of the main body part 10 when viewed from the Z direction. In the present embodiment, the short side portion 10b and the first bevel side portion 10c correspond to the end portion 10e of the body portion 10.

The massage part case 21 is formed by joining a plurality of members made of, for example, aluminum alloy.

A convex portion 22 is formed on one side of the massage part housing 21 located at an intersection 10f of the long side portion 10a and the first bevel side portion 10c when viewed from the Z direction.

The convex portion 22 protrudes in a direction substantially orthogonal to the first bevel portion 10c when viewed from the Z direction. The convex portion 22 has a first convex ridge portion 22d smoothly extending from the bottom portion 22a to the bottom portion 22c via the top portion 22 b.

A convex portion 23 is formed on the side of the massage part housing 21 located at the intersection 10g of the short side part 10b and the first bevel side part 10c when viewed in the Z direction.

The convex portion 23 protrudes in a direction substantially orthogonal to the first bevel portion 10c when viewed from the Z direction. The convex portion 23 has a second convex ridge portion 23d smoothly extending from the bottom portion 23a to the bottom portion 23c via the top portion 23 b. In the present embodiment, the convex portion 23 is larger than the convex portion 22.

A first concave portion 25 that smoothly connects the convex portion 22 and the convex portion 23 is formed between the convex portion 22 and the convex portion 23. The first concave portion 25 has a first concave ridge portion 25a extending smoothly.

A convex portion 24 is formed on the side of the massage part housing 21 located at the intersection 10h between the short side portion 10b and the second bevel side portion 10d when viewed in the Z direction. An intersection 10i of the long side portion 10a and the second bevel side portion 10d is formed at a position distant from the massage portion 20.

The convex portion 24 protrudes in a direction substantially orthogonal to the short side portion 10b when viewed from the Z direction. The convex portion 24 has a third convex ridge portion 24d smoothly extending from the bottom portion 24a to the bottom portion 24c via the top portion 24 b. In the present embodiment, the convex portion 24 is smaller than the convex portion 22.

Therefore, in the present embodiment, the convex portion 23 is highest and the convex portion 24 is lowest among the

convex portions

22, 23, and 24. That is, the distance between the top portion 23b and the main body portion 10 is the longest, and the distance between the top portion 24b and the main body portion 10 is the shortest. The top portion 22b is spaced from the main body portion 10 by a distance therebetween.

By providing 3 kinds of projections in this way, it is possible to massage with more appropriate projections.

A second concave portion 26 that smoothly connects the convex portion 23 and the convex portion 24 is formed between the convex portion 23 and the convex portion 24. The second concave portion 26 has a second concave ridge portion 26a extending smoothly.

In the present embodiment, the second concave portion 26 is curved more gently than the first concave portion 25 when viewed from the Z direction. That is, the second concave ridge portion 26a has a smaller curvature than the first concave ridge portion 25 a.

By providing such two kinds of concave portions, it is possible to massage the skin by pressing more appropriate convex portions against the skin. Specifically, the second concave portion 26, which is relatively gently curved, is suitable for massaging cheeks, forehead, and the like. The first recess 25, which is relatively curved and large, is adapted for massaging the chin.

In the present embodiment, the

bottom portions

22c, 23a, 23c, and 24a are inflection points of a curve drawn by the outer peripheral edge 20a when viewed from the Z direction.

The massage part housing 21 has a shape similar to the letter y when viewed from the Z direction.

As shown in fig. 5, the ridge line portion of the massage part housing 21 is included in the first surface 27 which is a flat surface, an inclined surface, or a gently curved surface when viewed along the XY plane. The ridge portion is a ridge portion including a first convex ridge portion 22d, a first concave ridge portion 25a, a second convex ridge portion 23d, a second concave ridge portion 26a, and a third convex ridge portion 24 d. Fig. 5 illustrates the first surface 27 including the second concave ridge portion 26 a.

A straight line parallel to the YZ plane and passing through the ridge line portion is defined as a reference line L, and one point on the reference line L is defined as a center point P1. At this time, the first surface 27 is a surface having a first radius of curvature R1 with reference to the center point P1. That is, the first surface 27 is a surface having a curvature of 1/R1.

The Z-direction length of the first face 27 is indicated by a first width W1. The first width W1 may be varied depending on the shape of the

projections

22, 23, and 24, instead of being constant along the ridge portion (see fig. 1 and 2).

The first face 27 is a plane where the first radius of curvature R1 is infinite, that is, a plane where the curvature approaches zero infinitely. However, the first face 27 may not be a strictly planar face.

The first surface 27 is formed in a region of at least the convex portion 22 and the second to third convex ridge portions 23d to 24d including the convex portion 23, of the ridge portions (see fig. 3). In the present embodiment, the first surface 27 is formed in a region from the top 22b of the convex portion 22 to the top 24b of the convex portion 24, among regions from the first concave ridge line portion 25a to the third convex ridge line portion 24d (see fig. 1 to 3).

The third surface 29 is a side surface of the massage part housing 21. One of both ends of the first surface 27 in the extending direction is connected to one of the two second surfaces 28, and is connected to one of the two third surfaces 29 via the second surface 28. The other of the two ends of the first surface 27 in the extending direction is connected to the other of the two second surfaces 28, and is connected to the other of the two third surfaces 29 via the second surface 28.

The two second faces 28 are each a face having a second radius of curvature R2, i.e., a face having a curvature of 1/R2 with respect to the center point P2. In this case, the two center points P2 are located on the same curve as the shape of the first face 27.

In the present embodiment, the curvature (1/R2) of the second surface 28 is larger than the curvature (1/R1) of the first surface 27.

That is, the first surface 27 is a flat surface or a curved surface close to a flat surface, and the second surface 28 is a curved surface having a relatively large curvature. Therefore, the second face 28 is likely to sink into the skin compared to the first face 27. Therefore, when pressed against the skin with the second surface 28 as the center, the skin can be easily pulled, for example. When pressed against the skin with the second surface 28 as the center, the skin can be locally vibrated, for example, to improve the massage feeling.

In the above example, the two second faces 28 each have the same curvature (1/R2). However, the two second faces 28 may have different curvatures from each other, respectively. In this case, when one of the two second surfaces 28 having a smaller curvature is pressed against the skin, a slightly stronger massage feeling can be obtained. When one of the two second faces 28 having a larger curvature is pressed against the skin, a stronger massaging feeling can be obtained.

The convex portion and the concave portion may be pressed not only against the above-described portions but also against other portions. That is, the beauty appliance 1 can massage a desired part of the human body according to the preference of the user or the person to be beautified.

The massage part housing 21 has a substantially constant thickness. That is, the reverse surface 27a of the first surface 27 is substantially parallel to the first surface 27. Likewise, the reverse surface 29a of the third surface 29 is substantially parallel to the third surface 29.

As shown in fig. 4 and 5, the massage part 20 has a heater 30 for heating at least a part of the massage part 20 inside thereof.

The heater 30 is thin plate-shaped as a whole. Preferably, the heater 30 is deformable according to the shape of the installation site. The heater 30 is, for example, a sheet heater including a sheath heater. The heater 30 is controlled by a control circuit provided on the circuit board 80. The circuit board 80 is disposed in the space S1 in the main body case 11.

The heater 30 is provided on a support portion 50 that supports the massage portion 20 such that a heating surface 30a of the heater 30 is close to a reverse surface 27a of the first surface 27. The length of the heating surface 30a of the heater 30 in the Z direction is the second width W2.

The first surface 27 is parallel to the heating surface 30a of the heater 30. That is, the heater 30 is opposed to the first face 27. This allows heat from the heater 30 to be efficiently transmitted to the projection 23 and the like. When the first surface 27 is a flat surface, the first surface 27 is parallel to the heating surface 30a of the heater 30. When the first surface 27 is a curved surface, the first surface 27 is substantially parallel to the heating surface 30a of the heater 30. That is, "parallel" in the present embodiment also includes "substantially parallel".

The heater 30 is disposed inside the at least one convex portion. Preferably, the heater 30 is arranged inside the protrusion 23 which is most frequently pressed against the skin. In this case, the heater 30 extends at least from the vicinity of the bottom portion 23a to the vicinity of the bottom portion 23c via the top portion 23b (see fig. 3).

The heater 30 extends from the convex portion 23 to the second concave portion 26. In this case, the heater 30 heats the range from the convex portion 23 to the second concave portion 26 at the massage portion 20 (see fig. 3).

The first width W1 is longer than the second width W2. In this case, the heat radiation surface of the massage part 20 has a larger area than the heating surface 30a of the heater 30. Thereby, the thermal gradient between the heat radiating surface of the massage part 20 and the heating surface 30a of the heater 30 is increased, and the flow of heat to the outside of the first surface 27 is reduced. Thus, the heat from the heater 30 is efficiently supplied to the massage part 20.

Conversely, the first width W1 may also be shorter than the second width W2. In this case, the heat flux at the first face 27 increases. This enables the temperature of the projection 23 and the like to be raised more quickly. Thus, the massage unit 20 is heated by the heater 30, and thus can provide a warm feeling to the skin.

The heater 30 is provided on the reverse surface 27a of the first surface 27. Thus, the first surface 27 having a relatively wide area serves as a main heat radiating surface of the massage unit 20. As a result, the user can more easily obtain a warming sensation.

The massage part 20 is made of an aluminum alloy having high heat transfer efficiency. Thus, the massage part 20 can efficiently transfer heat from the heater 30 to the first surface 27 or the second surface 28.

The massage part 20 has a vibration part 40 therein which applies relative vibration to the massage part 20 with respect to the main body part 10. The vibration unit 40 includes, for example, a motor 41 and an eccentric shaft 42, the motor 41 having a motor body 41a and a motor shaft 41b, and the eccentric shaft 42 being connected to the motor shaft 41 b.

The motor 41 is electrically connected to the control circuit. The eccentric shaft 42 is composed of, for example, a motor shaft 41b and an eccentric spindle attached to the motor shaft 41 b. The center axis of the eccentric ingot is offset from the center axis of the motor shaft 41 b. When the motor shaft 41b rotates, the centrifugal force of the eccentric spindle acts on the motor 41 to vibrate the massage unit 20.

The vibrating portion 40 is disposed in the space S3 in the highest convex portion 23 of the plurality of convex portions. That is, the vibration unit 40 is disposed at the distal end of the massage unit 20. Specifically, the vibration unit 40 is disposed such that the eccentric shaft 42 is located at a position close to the top portion 23b (see fig. 3) of the space S3 in the convex portion 23.

This enables a large torque to be generated by the eccentric shaft 42 at the same rotational speed of the motor 41. Therefore, the vibration can be more effectively applied to the massage part 20. Since the eccentric shaft 42 and the motor 41 can be downsized, the beauty appliance 1 can be downsized and the cost can be reduced.

The vibration unit 40 provided in the massage unit 20 mechanically vibrates the massage unit 20. Thus, when the massage unit 20 is pressed against the skin, the user can apply physical stimulation to the skin without moving the cosmetic device 1.

When the user moves the cosmetic device 1 while pressing the massage part 20 against the skin in a vibrating state, physical stimulation generated by moving the massage part 20 by hand and physical stimulation generated by vibration of the massage part 20 can be applied to the skin.

The massage unit 20 and the main body 10 are configured to be independent of each other. The massage unit 20 needs to be supported by the main body 10 so as to be capable of vibrating relative to the main body 10. In the present embodiment, the massage unit 20 is supported by the main body 10 via the support unit 50.

The circuit board 80 is provided with the first switch portion 62 of the vibration mode changeover switch 60 and the second switch portion 66 of the heater changeover switch 64. First switch unit 62 is a switch for switching the vibration mode of vibration unit 40. The second switch portion 66 is a switch for switching on and off the heating by the heater 30.

The first switch 62 and the second switch 66 are electrically connected to the control circuit. A first operation button 61 is provided so as to face the first switch unit 62. A second operation button 65 is provided so as to face the second switch portion 66.

The first operation button 61 and the second operation button 65 are provided on the long side portion 10a of the main body 10, that is, the side surface 11b of the main body case 11, so as to be aligned in the X direction.

When the first operation button 61 is pressed, the first operation button 61 presses the first switch portion 62. When the first switch 62 is pressed, a signal corresponding to this is generated. The control circuit switches the vibration mode of the vibration unit 40 in accordance with the signal.

When the vibration unit 40 is operated, a desired mode can be selected from a plurality of vibration modes having different vibration cycles and different vibration intensities. The control circuit stores the above plurality of vibration patterns.

When the second operation button 65 is pressed, the second operation button 65 presses the second switch portion 66. When the second switch portion 66 is pressed, a signal corresponding thereto is generated. The control circuit switches the heating by the heater 30 on and off in accordance with the signal.

The control circuit may change the heating temperature in a plurality of stages, instead of switching the heating on and off.

The power of the beauty appliance 1 can be turned on and off by pressing the first operation button 61. That is, in the present embodiment, the power supply is also defined to be turned on and off by switching the vibration mode of the vibration unit 40. A switch section for turning on and off the power supply and an operation button may be provided in addition to the vibration mode changeover switch 60.

A plurality of LEDs (light emitting diodes) 72 are mounted on the circuit board 80. The plurality of LEDs 72 are each controlled by a control circuit. The plurality of LEDs 72 may also emit different colors of light from each other.

The light guide portion 71 is formed so as to face the LEDs 72. Light guide portion 71 is provided in main body case 11 so as to be exposed from side surface 11 b. The light guide portion 71 transmits light from at least any one of the plurality of LEDs 72 to the outside.

The user can confirm which vibration mode is selected and whether or not the heater 30 is on, based on the light transmitted from the light guide portion 71. When the remaining battery power decreases, the plurality of LEDs 72 light up in a manner different from usual by blinking or the like. This makes it possible to notify the user of the remaining battery level.

As described above, the beauty treatment instrument 1 of the present embodiment includes the flat main body 10 having the space S1 therein. The beauty appliance 1 includes a massage part 20, and the massage part 20 is provided at an end 10e of the main body 10 when viewed from the thickness direction (Z direction) of the main body 10, and the outer peripheral edge 20a of the massage part 20 has at least one convex portion 23.

The convex portion 23 has a ridge line portion extending from the top to the bottom when viewed in the thickness direction of the main body portion 10. The convex portion 23 has a heater 30 therein. The heater 30 is opposed to the first surface 27 including the ridge portion. Both ends of the first surface 27 in the thickness direction of the main body 10 are connected to the second surface 28. The curvature (1/R2) of the second face 28 is greater than the curvature (1/R1) of the first face 27.

In the present embodiment, the massage part 20 pressed against the skin of the user is heated by the heater 30. In particular, since the massage unit 20 has a sufficient width up to the tip, the heater 30 can be disposed close to the ridge line portion. The structure is more beneficial to the user to feel warm.

When the user changes the angle of the cosmetic device 1 with respect to the skin by a little, the second face 28 having a curvature larger than that of the first face 27 can be made to hit the skin. This allows the stimulus such as pressing to be changed by a simple operation in addition to the stimulus caused by heat. Therefore, the massage effect can be improved by the stimulation with the warm heat.

In the present embodiment, the first surface 27 is parallel to the heating surface 30a of the heater 30. This enables efficient heat transfer from the heater 30 to the convex portion 23 and the like.

In the present embodiment, the length of the first face 27 in the thickness direction of the main body portion 10, i.e., the first width W1 shown in fig. 5, is longer than the length of the heater 30 in the thickness direction of the main body portion 10, i.e., the second width W2 shown in fig. 5.

This increases the area of the heat radiating surface of the massage unit 20, and increases the thermal gradient between the heat radiating surface and the heating surface 30a of the heater 30. Therefore, the flow of heat to the outside of the first surface 27 is reduced. As a result, heat from the heater 30 is efficiently transferred to the first face 27.

In the present embodiment, the length of the first surface 27 in the thickness direction of the body 10 may be shorter than the length of the heater 30 in the thickness direction of the body 10.

Thereby, the heat flux at the first face 27 increases. As a result, the temperature of the convex portion 23 and the like can be increased relatively quickly.

In the above embodiment, the heater 30 is provided at least inside the convex portion 23 and the like so that the heating surface 30a is close to the reverse surface 27a of the first surface 27. In this case, an air layer exists between the heating surface 30a of the heater 30 and the reverse surface 27a of the first surface 27.

(embodiment mode 2)

Fig. 6 is a sectional view of the beauty treatment apparatus 1 according to embodiment 2 of the present disclosure. Fig. 7 is a cross-sectional view of the beauty treatment apparatus 1 according to the present embodiment taken along line 5-5 of fig. 3, corresponding to fig. 5.

In the present embodiment, the same components as those in embodiment 1 are denoted by the same reference numerals as those in embodiment 1, and redundant description thereof is omitted. In the present embodiment, as shown in fig. 6 and 7, the adhesion member 32 is disposed between the protruding portion 23 and the heater 30. The adhesive member 32 has a higher thermal conductivity than air.

The sticking member 32 may be a liquid substance having a high viscosity, for example. Such a liquid substance includes, for example, a heat-dissipating grease such as silicone grease in which metal powder having excellent thermal conductivity is mixed.

Thereby, the back surface 27a of the first surface 27 including the ridge line portion and the heating surface 30a of the heater 30 are brought into contact with each other through the adhesive member 32. No air layer exists between the second concave ridge portions 26a and the like and the heater 30. As a result, the heater 30 can sufficiently heat the massage part 20.

The protruding portion 23 and the like have a gap in a portion where the attachment member 32 is not disposed. Fig. 6 shows, as examples of such voids, a void C1 formed inside the projection 23 and a void C2 formed inside the projection 22. In fact, the void C1 and the void C2 are in communication with each other. Fig. 7 illustrates a void C3 formed inside the second recess 26.

The gaps C1, C2, and C3 are air-filled spaces and function as heat-insulating spaces. This can reduce heat leakage from the portion where the attachment member 32 is not disposed.

The vibration unit 40 is provided inside the massage unit 20. The vibrating portion 40 has an eccentric shaft 42. The eccentric shaft 42 is parallel to the normal line of the heating surface 30a of the heater 30.

The heating surface 30a of the heater 30 has a shape corresponding to the shape of the massage part 20, i.e., the shape of the first surface 27. However, the heating surface 30a of the heater 30 is basically constituted by a surface parallel to the Z direction. Thus, the normal line of the heating surface 30a is an imaginary line on the XY plane. In the present embodiment, as shown in fig. 6, the eccentric shaft 42 is parallel to an imaginary line on the XY plane.

In this way, the eccentric shaft 42 and the heater 30 are disposed inside the convex portion 23 such that the eccentric shaft 42 is parallel to the normal line of the heating surface 30 a. This can suppress the displacement of the attachment member 32 due to the operation of the vibration unit 40.

While the preferred embodiments have been described above, the embodiments of the present disclosure can be variously modified within the scope of the gist thereof. For example, in the above embodiment, the first surface 27 is a smooth surface. However, for example, the first surface 27 may have irregularities in a range that does not affect the stimulus generated by pressing or heating.
