Similarly, it is a perspective view of the light emission part in the state which removed the light irradiation part cover, and a cooling means. It is explanatory drawing which shows the flow of the airflow which concerns on this invention.

FIG. 1 is an external perspective view of a cosmetic device according to the present invention, in particular, a light irradiation type hair removal device (hereinafter, the present device) (1). FIG. 2 is a cross-sectional view in a right side view. The present invention is not limited to the present embodiment, and can be modified as appropriate.
The apparatus (1) has a substantially rod-like appearance in the longitudinal direction at the top and bottom, and the center part and the lower part have grip parts (2) that the user grips, and the upper part has various functions for performing hair removal treatment A processing unit (3) is disposed.

  The grip portion (2) has a central portion smaller in diameter than the top and bottom so as to be easily gripped, and forms a substantially drum shape as a whole, and is provided with an operation switch (20) for turning on and off the light irradiation function. Further, the lower end face of the device (1) is provided with a power port (21) necessary for charging. In the present device (1), although the rechargeable type is used, the present invention is not limited to the rechargeable type, and may be a power supply type using an external power supply or a dry cell.

  As shown in FIG. 2, the present device (1) comprises a frame body (10) for fixing each mechanism, and a cover body (11) for giving designability around it, and the frame body (10) is provided on the lower end face In addition to the exposure, the cover body (11) is divided into left and right overall covers (11a) and (11b) constituting the left and right side surfaces, an upper surface cover (11c), and a light emitting unit cover (11d).

A rechargeable battery (30) is accommodated in the upper portion of the frame body (10), and power supplied from the power supply port (21) is transformed by the power supply circuit board (22) and charged, and It is designed to supply power to 1).
The rechargeable battery (30) may be fixed so as not to be replaced, or the top cover (11c) may be removed so that it can be replaced when it is exhausted.

  The upper surface cover (11c) is provided with a plurality of setting switches (31) for operating the present device (1), for example, switching the mode of the light irradiation function, controlling the cooling means, and the like. The operation switch (20) and the setting switch (31) may be distributively arranged according to the operation frequency and the gripping state at the time of operation, and the setting switch (31) may be erroneously pressed during hair removal processing or the operation may be confused. I try not to.

  A skin guide surface (12) is formed on the front of the light irradiator cover (11d) to be held in contact with the processing target while being held by the user, and the cooling means (13) which is the main part of the present invention is formed thereon And the irradiation window part (14) to which the light from the light emission part mentioned later is irradiated in the downward direction is arrange | positioned.

According to this configuration, when the user brings the skin guide surface (12) into contact with the skin, the portion to be treated can be cooled by the cooling means (13), and light can be emitted from the light emitting unit. The device (1) is long in the vertical direction and has a substantially drum-like shape, so it is easy to slide the device in the vertical direction. For example, in the case of sliding downward from above, immediately after light irradiation The site to be treated can be cooled to calm down the skin after treatment.
On the other hand, in the case of sliding upward from the bottom, the region to be treated is cooled in advance to temporarily paralyze the sense, and the stimulation by light irradiation can be reduced.

Therefore, the cooling means (13) and the irradiation window (14) according to the present invention are preferably arranged on the same surface as the skin guide surface (12) and arranged in parallel according to the sliding direction in use. For example, in a configuration in which it is easy to slide left and right, it is appropriate to provide cooling means (13) on the left and right sides of the irradiation window (14).
The cooling means (13) is not limited to either one of the irradiation windows (14), but may be provided on both sides. Also, for example, they may be arranged all around.

  The shape of the irradiation window may not be rectangular as in this embodiment, and may be, for example, circular or elliptical. The shape of the cooling means is also optional, but the design can be enhanced by making the shape conform to the shape of the irradiation window.

Furthermore, the apparatus (1) may be provided with a replaceable illumination window forming an illumination window (14). As a simple configuration of the irradiation window, a plurality of types of window sizes are prepared in accordance with the position of the processing target site, and the irradiation window is provided so as to be removable.
For example, when performing hair removal processing in a narrow range, a small irradiation window of the irradiation window is attached and processed. In addition, the amount of light irradiated to the skin surface can be adjusted by changing the size of the irradiation window.

  FIG. 3 is a perspective view of the light emitting unit (15) and the cooling means (13) with the light emitting unit cover (11d) removed. In the present invention, a xenon tube (150) and a reflector (151) are used for the light emitting portion (15), and the xenon tube (150) is installed on a light source substrate (152) provided on the back surface.

The light source substrate (152) is provided with a booster circuit, a charge circuit, and a capacitor unit (not shown), and the capacitor unit is charged with the boosted current. The electricity stored in the capacitor portion is discharged by operating the operation switch (20) to flash the xenon tube (150).
Flash light may be emitted only once by operation, or may be continuously charged and emitted at a predetermined cycle.

  The light from the xenon tube (150) has an optical path directly to the irradiation window (14) and an optical path reflected to the inner surface of the semicircular reflector (151) and then to the irradiation window (14). Also in the case of the light path of the above, it passes through the glass filter (153) provided on the front side. The glass filter mainly protects the xenon tube (150) and the like, but has a UV cut function for cutting ultraviolet rays harmful to the skin and a light reduction function for adjusting the amount of light.

  The glass filter (153) may be configured to be exchangeable in order to adjust the amount or wavelength of the irradiation light. Moreover, you may make it replaceable with an irradiation window body by attaching to the above-mentioned irradiation window body.

  A light guide plate (154) is provided around the inner surface of the irradiation window (14) to maintain the distance to the skin guide surface (12) so that the skin does not directly contact the glass filter (153). The light from the xenon tube (150) is irradiated without being directed to the processing target portion applied to the irradiation window (14). The light guide plate (154) is not intended to adjust the wavelength from the xenon tube, and is basically composed of a metal body that totally reflects light. Alternatively, a low reflective or light absorbing material may be used.

On the other hand, the cooling means (13) uses a Peltier element (130). As is well known, the Peltier element is a semiconductor element having a thermoelectric effect, and one surface of a flat body is a heat absorbing surface, and the other surface is a heat generating surface. In the present embodiment, an electric current is supplied by the power supply line (131) so that the heat absorption surface (130a) is on the outside, and a heat sink (132) is connected to the heat generation surface (130b) toward the rear.
The Peltier element (130) can be miniaturized as a cooling means, but heat radiation is important because it is a cooling method by heat transfer, and in this embodiment, efficient heat radiation is achieved by a large heat sink (132).

  In the light irradiation type hair remover of the present invention, the xenon tube (150) is accompanied by a large amount of heat generation, and appropriate heat radiation from the light source substrate (152) including the capacitor portion and the cooling means is important. For example, Patent Document 3 describes that a cooling fan is provided and air whose temperature is increased by the thermoelectric cooling plate is taken out from a slit window provided above the thermoelectric cooling plate. However, if the air blown by the cooling fan sucks in air including the high temperature air generated by the flash lamp with more heat generation, it may not contribute to the cooling effect of the thermionic cooling plate, but rather may raise the temperature.

In view of these, the present invention is provided with a fan (16) for simultaneously cooling the cooling means (13) and the light emitting part (15). The fan (16) promotes heat radiation from the heat sink (132), and generates an air flow for cooling the light emitting portion (15).
In particular, three air flow paths are preferably provided. Specifically, an air intake port for taking in air taken in by a fan (16), a first air flow path from the air intake port to the cooling means (13), and cooling A second air flow path from the means (13) to the light emitting part (15) and a third air flow path from the light emitting part (15) to the exhaust port are provided.

FIG. 4 is an explanatory view showing the flow of the air flow according to the present invention. The top cover (11c) and the light irradiator cover (11d) have a plurality of holes formed therein to form an air inlet (160) capable of taking in air in a wide range from the top of the apparatus (1) There is.
By using a large number of holes, the first air flow path (161) in which the air is guided to the heat sink (132) of the cooling means (13) is configured while suppressing the noise associated with the intake.

The first air flow path (161) passes through the collar (132a) (see FIG. 3) of the heat sink (132) and is guided to the fan (16) by the rectifying cover (162). Air from the fan (16) is blown to the back side of the reflector (151) of the light emitting part (15) through the slit (152a) of the light source substrate (152).
A portion from the heat sink (132) to the reflector (151) is a second air flow path (163). In this embodiment, by providing the fan (16) in the middle of the second air flow path (163), the heat sink (132) applies the intake air from the wide air inlet, and the reflector (151) intensively has a high flow rate of air. It is configured to be able to

  Further, the air warmed by being in contact with the reflector (151) is forcedly exhausted from the fan (third air flow path (164)) to the lower surface and the entire left and right cover (11a) (11b) of the light irradiation part cover (11d). The air is exhausted from an exhaust port (165) opened at a part of The exhaust port (165) also has a sufficient opening area to suppress exhaust noise.

  Since the present invention constitutes the first to third air flow paths as described above, it is possible to dissipate the heat of the relatively high temperature light emitting portion after performing the heat dissipation of the relatively low temperature cooling means. It can contribute to the improvement of the heat radiation efficiency. That is, by promoting the heat radiation from the heat sink (132), the cooling effect by the Peltier element (130) is enhanced, which also contributes to the long life and power saving of the element. In addition, the light source substrate (152) on the back side of the heat sink (132) is protected from becoming hot by directly applying the air from the fan to the reflector (151) for cooling, and the xenon tube (150) Ambient air can also be cooled.

By providing the intake port on an intake surface different from the skin guide surface and the exhaust port on an exhaust surface different from the skin guide surface and the intake surface, air flow is not applied to the skin surface, and a comfortable usability can be realized.

  As the light source in the light emitting portion of the present invention, various known light sources can be used besides the above-described xenon tube. For example, any light source used in a hair removal apparatus such as a laser light source, an incandescent lamp light source, or a light emitting diode light source may be used.

  Further, the cooling means is not limited to the Peltier element, but may be a metal plate having high thermal conductivity or the like, or a cold insulating gel which is previously cooled by a refrigerator or the like. The present invention can be suitably changed in the range which uses the above-mentioned air flow in order to perform heat dissipation from a cooling means.

The present invention is not limited to the light irradiation type hair removal device (1) having only the hair removal function as described above, and can also be provided as a cosmetic device provided with other beauty function. That is, the device (1) can be equipped with a cosmetic function simultaneously with or as a replaceable type of light-emitting type hair removal mechanism.
Examples of the beauty function include an ion introduction / extraction device, a heater, a mist generation device, an ultrasonic wave generation device, a vibrator, a moisture meter, a low frequency generation device, a high frequency generation device, a laser light irradiation device and the like.

2. Description of the Related Art There have conventionally been provided various cosmetic devices for performing beauty treatment on the face, head, and other body parts while the user holds them by hand. For example, an iontophoretic device (see Patent Document 4) that releases negative ions to enhance the penetration effect of cosmetic solution (see Patent Document 4), an ion extractor that enhances the effect of removing dirt with positive ions, a heater function, and a mist generating device that moisturizes the skin (patent Reference 5), an ultrasonic (sonic) generator that gives a fine stimulus to the skin by ultrasonic vibration (see Patent 6), a vibrator, a moisture meter that measures the amount of water on the skin, and massages muscles with a weak current A low frequency generator (see Patent Document 7) and a high frequency generator, and a laser beam irradiation apparatus (see Patent Document 8) for causing keratinization or stains and dullness by laser light or removing hair are known.
The present invention can also provide a cosmetic device to which these cosmetic functions are appropriately applied.

Then, as shown in FIG. 5B, when the skin surface is pressed from above, the openable and closable roller bodies (201) and (202) open on the left and right sides. At this time, due to the friction between the openable and closable roller body (201) (202) and the skin surface, the portion to be treated becomes in tension in the left and right sides.

When the light emission part (203) comes in close contact with the skin surface, flash light is irradiated to perform hair removal processing.
As shown in FIG. 6 (a), when the hair remover main body (200) is released upward after the hair removal treatment, the openable and closable roller bodies (201) and (202) are closed to the center side again.

At this time, the reclosable roller body (201) (202) can be closed while rolling on the processing target portion, and the skin surface can be cooled by the cooling function of the reclosable roller body (201) (202). That is, by forming the circumferential surface of the openable / closable roller body (201) (202) of metal with high thermal conductivity, it can be instantaneously cooled by rolling on the burnt skin surface after the treatment. it can.
