It is a perspective view of the neck cosmetology device which concerns on this invention. It is a top view of the neck cosmetology device which concerns on this invention. It is a rear view of the neck cosmetology device which concerns on this invention. It is a figure which shows the electrode of the rear side electrode part. It is a figure which shows the electrode of the front side electrode part. It is an exploded perspective view near the support part. It is a front side transmission view of a cosmetological device main body.

Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings. The embodiment is not limited to the following. FIG. 1 is a perspective view of the cervical beauty device according to the present invention, FIG. 2 is a plan view of the same, and FIG. 3 is a rear view of the same.
The cervical cosmetological device of the present invention (hereinafter, simply referred to as a cosmetological device) (1) is a cervical cosmetological device used by being worn on the neck of the user, and is on the back side, that is, on the back of the user when worn. It has a substantially annular beauty device body (10) having an open portion (10a) with a part open on the side.

The left and right front electrode portions (20) (20) that abut on the front surface of the neck and the left and right rear electrode portions (20) (20) that are attached to the cosmetology device body and abut on the side surface or the back surface of the neck ( 21) (21) are provided, and the entire beauty device main body (10) can be held by contacting the front electrode portion (20) and the rear electrode portion (21) with an appropriate pressure to the neck. ..

The beauty device body (10) has flexibility in the radial direction of the neck, that is, in the direction of expanding according to the thickness of the neck, the exterior is made of silicon, and the leaf spring-like member is incorporated over almost the entire length. Then, the front electrode portion (20) and the rear electrode portion (21) are pressed against the neck by an appropriate elastic force.

The front lower end of the beauty device body (10) has a downward convex portion (101) that abuts between the sternoclavicular joints of the user, so that the anterior electrode portion (20) is displaced downward. It is formed to prevent it. In addition, when viewed from the front, it gives a sharp V-shaped impression and contributes to the design.

In addition, the beauty device main body (10) of the present embodiment is formed by bending so as to be convex downward while maintaining a substantially uniform height on the front side. In this case, since a sufficient height is also formed on the front side, it is possible to arrange the lamps, which will be described later, and to secure a space for incorporating the control board inside.
Further, since the V-shape is also formed on the upper side of the front surface, it is possible to avoid the chin and eliminate the discomfort, and the overall elegant design is realized.

Next, the electrode portion of the present invention will be described. FIG. 4 shows the surface of the electrode portion of the rear electrode portion (21) that comes into contact with the neck portion. In the present invention, the rear electrode portion (21) is a substantially flat surface curved along the roundness of the neck, and each includes two electrodes (210) and (211). The two electrodes (210) and (211) are arranged in two stages on the top and bottom, but may be arranged in parallel on the left and right.

Then, an electric current for giving an electrical stimulus is applied between the electrodes (210) and (211). The rear electrode portion (21) exerts electrical muscle stimulation called EMS (Electrical Muscle Stimulation) to which a current of a predetermined frequency is applied. It is widely known that EMS has the effect of causing muscle contraction to cause muscle exercise and relieve tension by applying electrical stimulation to the skin at a frequency of several Hz to several kHz.

In addition to training facial muscles such as the sternocleidomastoid muscle with EMS to remove wrinkles and slack, drainage treatment with EMS is performed on the lymph nodes around the neck to improve lymphatic flow and activate metabolism. can do.

Since relatively large electrical stimulation is given in EMS, it is preferable not to apply the stimulation to the center of the neck along the spine in the neck. Therefore, in the present invention, two electrodes (210) and (211) are provided for each of the left and right rear electrode portions (21), and electricity is supplied only between the electrodes so that electricity does not flow between the left and right electrodes. ing.
The rear electrode portion (21) is not limited to two poles as in this embodiment, and may be provided with a large number of electrodes such as three poles and four poles. Even in this case, it is desirable to arrange the left and right so as not to energize.

The rear electrode portions (21) and (21) are supported by the cosmetic device main body (10) via elastic hollow truncated cone-shaped support portions (22) and (22). FIG. 6 is an exploded perspective view of the vicinity of the support portion (22). As shown in the figure, the support portion (22) is formed of a silicon material having a predetermined thickness and has a conical trapezoidal shape with a hollow inside, and a rear electrode portion (21) is attached to the upper surface (220) thereof. Wiring or the like from the hole (221) to the electrodes (210) (211) is passed through.

In this embodiment, a thick portion (222) is provided as a reinforcing element on the hollow truncated cone-shaped side surface of the support portion (22) so that the rigidity of the portion is higher than that of the other portions. The thick portion may be configured to increase the thickness of the side surface, or may be formed by projecting in a rib shape.
Further, since the purpose is to reinforce, another material may be attached to the portion as a reinforcing element.

In this way, when the support portion (22) that supports the rear electrode portion (21) is formed of a relatively thin elastic body and the shape is formed by a wide skirt, the wall thickness of a part is increased. By increasing the rigidity, the compression balance of the elastic body is lost, and the electrodes are more softly sunk inward of the beauty device body (10) (Fig. 6 shows the state of being sunk toward the front side). The cosmetological device body (10) can be fitted to the neck.

As shown in FIG. 2, it is desirable that the upright surface (223) in contact with the beauty device main body (10) is arranged substantially parallel to the facing position of the neck with respect to the support portion (22). That is, in a plan view, the distance between the left and right sides on the back side is slightly narrower than that on the front side, which corresponds to the neck becoming narrower toward the back side.
With this configuration, the rear electrode portion (21) can be evenly contacted with the neck.

Similarly, as shown in FIG. 2, the distance between the left and right farthest portions (d ₁ ) of the front electrode portion (20) is larger than _{the distance between the left and right portions (d 2} ) at the front end of the rear electrode portion (21). ing. With such a positional relationship, when the open portion of the cosmetological device main body (10) is opened and attached around the neck, the rear electrode portion (21) firmly contacts the neck and can be energized and held. , The front electrode portion (20) makes it difficult to feel suffocation, and a good feeling of use can be obtained.
The above-mentioned interval is a distance in a free state in which the open portion is not widened, and of course, it changes when the open portion is widened by hand.

In this embodiment, the rear electrode portion (21) has a built-in heater. The heater warms the lymphatic part of the neck, which is effective in promoting lymphatic and blood circulation and inducing sleep. In particular, by forming the electrode portion of the rear electrode portion (21) with metal, it is excellent in heat transfer property, and even a heater having low output and low power consumption can sufficiently exert an effect.

FIG. 5 shows the electrode (204) of the front electrode portion (20). A weaker current is applied to the front electrode portion (20) as compared with the rear electrode portion (21). Since the anterior electrode portion (20) hits the anterior surface of the neck and the portion is sensitive to stimuli, according to the inventor's experiment, when a current used for EMS is applied, the stimulus is too strong and discomfort is caused. Give rise.

Therefore, in the present invention, a weak electric current is passed through the front electrode portion (20) to introduce ions having a moisturizing effect on the skin. Iontophoresis is such that the lotion is charged with negative ions and adsorbed on the skin to easily permeate. For example, iontophoresis is performed by applying a direct current of about 1 V to 20 V or a pulse current.
The pulse current suitable for iontophoresis is preferably, for example, an output voltage of about 5 V and a frequency of 1.5 kHz.

In addition, in both the front electrode portion (20) and the rear electrode portion (21), an RF current, for example, a high frequency of about 1 Mhz is used to warm the inside of the skin, promote the production of collagen and elastin, and wrinkle, firmness, and wrinkles. It is also possible to improve the slack.

The front electrode portion (20) is symmetrical on the left and right sides, and has a substantially flat plate shape curved along the roundness of the neck. FIG. 5 shows the front electrode portion (20) on the right side. Then, the corner of the surface that comes into contact with the front surface of the neck is R-chamfered, and the R diameter of the inner upper corner (200) and the outer lower corner (202) is made larger than the other corners (201) and (203). Form. Since it is symmetrical, the left side has a mirror image of FIG.

With this configuration, not only does the front electrode portion (20) not protrude up and down to match the shape of the front surface of the beauty device body (10), but also it is possible to avoid contact with the skin above the Adam's apple and clavicle, which makes it feel uncomfortable. You can get a comfortable feeling of use.

Next, the control and power supply of the present invention will be described.
This beauty device (1) houses the power supply inside the main body, making it a wearable product. The cosmetology device main body (10) is equipped with a control power supply unit that supplies and controls a power source for energizing an electric current, and is configured to be operable only by the cosmetology device main body.

As shown in FIG. 7, among the control power supply units, the control board (110) is first arranged at the center of the front end of the beauty device main body (10). Since the beauty device main body (10) is flexible and bends in the radial direction, the vertically long control substrate (110) is arranged at the position where the fluctuation is the least. As a result, cracks in the substrate are less likely to occur, and the life of the substrate can be extended.

For the same purpose, the control board (110) and the housing of the beauty device main body (10) are connected to be perpendicular to the direction plane in which the beauty device main body (10) opens or the central surface of the beauty device main body (10). It is done on the straight line above.

It is not necessary that all the substrates are provided in this portion, and they can be appropriately dispersed and arranged.

On the control board (110) of this embodiment, an LED (111) that displays the level and the operating state is installed on the front surface. Four LEDs (111) are arranged in the vertical direction, but this is devised so as not to be misunderstood even when viewed in a mirror, and the design from the front is enhanced.

Further, regarding the control power supply unit of the present invention, a part of the predetermined weight ratio of the control power supply unit is arranged on the back side of the rear electrode portion (21), and the rear electrode portion (21) is biased to the front side with the rotation center as the center of rotation. It is preventing that.
Specifically, the center of gravity of the rechargeable battery is positioned on the back side of the rear electrode portion (21) so that the balance at the time of mounting is good and rotation deviation does not occur.

As the weight ratio, the ratio of the total weight of the members in front of the rear electrode portion to the total weight of the members in the rear is in the range of 3: 1 to 1: 2, with the center in the front-rear direction as the boundary. Is particularly suitable.
More preferably, it is optimal that the position of the entire center of gravity in the front-rear direction is contained in any portion of the rear electrode portion.
