Description

  The present invention relates to an optical beauty device and a handpiece thereof, and more particularly, to a technique for enhancing safety when performing hair removal, facial beauty, and other cosmetic treatments.

  2. Description of the Related Art As a hair removal beauty device, a device that makes body hair or the like ash in an instant by an optical technique and suppresses its regeneration (hereinafter referred to as “optical beauty device”) is well known. This optical beauty device emits light from a light source and irradiates the hair to be removed, etc., to instantaneously turn the hair into ashes in an instant and suppress the regeneration thereof. This optical beauty device reacts to the color of body hair and the like, turns them into ash in an instant, and develops a function of suppressing the regeneration.

  FIG. 8 shows a conventional optical beauty device 100, and FIG. 9 shows a conventional handpiece 101. The optical beauty device 100 is roughly composed of a hand piece 101 and an apparatus main body 102. The apparatus main body 102 performs control to cause the light source to emit light at a predetermined time interval, and performs control to cool heat generated by the light emission. The handpiece 101 includes a light emitter 103, a protective glass 104, an irradiation filter 105, an irradiation window 106, and the like. The handpiece 101 is used by the practitioner to irradiate light on a hair removal portion or a beautiful face portion.

  Here, “cooling control”, that is, “cooling control”, is classified into two types, an air cooling method and a water cooling method. The cooling control is performed because the heat caused by the light irradiation from the light emitter 103 is caused by overheating of the skin of the customer (person who receives the hair removal process) or the handpiece 101 held by the practitioner (person who performs the hair removal process). It is for preventing. Among these, the air cooling system is a mechanism for cooling by creating an air flow in the vicinity of the light irradiation site. For this reason, the optical hair removal device adopting the air cooling method needs to cause an air flow, and therefore, a gap is consciously or unconsciously formed between members constituting the handpiece. The water cooling system is a mechanism for cooling by flowing a water flow through a tube or the like in the vicinity of the light irradiation site. For this reason, an optical hair removal device that employs a water cooling system has a hermetically sealed structure in the vicinity of the cooling site because of the occurrence of water flow.

  As a light emitter (light source) of a conventional general optical hair removal apparatus having such a configuration, a xenon lamp is well known regardless of the cooling method. This xenon lamp irradiates light including an ultraviolet region. Therefore, a conventional general optical beauty device using a xenon lamp as a light emitter has a mechanism for cutting out at least the light in the ultraviolet region of the irradiated light and extracting only light having a wavelength necessary for hair removal purposes. Is done. That is, the conventional general optical beauty equipment has a mechanism for cutting the irradiation light including the ultraviolet region in order to set the light wavelength during irradiation to the long wavelength side (including the visible light region and the infrared region).

  As a mechanism for ultraviolet protection, a method of depositing a component that cuts ultraviolet rays on the surface of a xenon lamp (illuminant 103), or a protective glass 104 and an irradiation filter 105 that deposits an ultraviolet cut component on the irradiation light side of the xenon lamp are provided. Techniques are known. An example of this is disclosed in Patent Document 1.

Special table 2002-500080

However, in the case of the air cooling method, there is a problem that light including an ultraviolet region to be cut out of light irradiated from the xenon lamp is irradiated to the customer's skin and the practitioner's hand through the gap of the handpiece. there were. This is because the air cooling system does not have a water flow and is not designed in consideration of water leakage, and any hole or gap can be an air flow path in terms of structure.
In both cases of air cooling method and water cooling method, when a UV-cut vapor-deposited film is applied to the surface of xenon lamp, protective glass, and irradiation filter, accumulating usage time above 300 ° C. The deposited film is peeled off. When this ultraviolet cut vapor deposition film peeled off, there was a problem that the ultraviolet rays leaked from the peeled portion and irradiated to the customer's skin and the practitioner's hand.

  If the optical hair removal device is used excessively in a state where ultraviolet rays leak in this way, it causes damage to the skin for the purpose of hair removal. The use in the state where ultraviolet rays leaked is almost no problem if it is performed once a month, but when the hair removal treatment is performed from morning to night, an unnecessary burden is placed on the customer's skin. In particular, when an ultraviolet-cut component is deposited on the surface of the xenon lamp, the xenon lamp must be replaced because the deposited film is peeled off, and there is no problem with the light emitting function, but waste occurs. There was also a problem.

  Next, FIG. 10 is a diagram showing the relationship between the conventional irradiation distance SL, the appropriate distance AL, and the substantial distance JL. First, terms will be explained. “Irradiation distance SL” refers to the distance between the forefront surface of the light emitter 103 and the end surface of the irradiation window 106. The “appropriate distance AL” refers to the minimum distance that should be secured between the forefront of the light emitter 103 and the skin S of the customer. “Real distance JL” means an actual distance between the forefront of the light emitter 103 and the skin S of the customer. The irradiation window 106 is irradiated with light while being in contact with the skin S of the customer, and functions to fix the irradiation position of the light emitter 103.

  However, the conventional optical hair removal device 100 has a problem that the appropriate distance AL cannot be sufficiently secured. Conventionally, the irradiation distance SL is a short distance of about 12.5 mm (by the way, the thickness TH of the irradiation window 106 is about 2 mm), which is the same value as the appropriate distance AL. Conventionally, the irradiation distance SL has been shortened because hair removal is considered to be performed by thermal energy, so that the customer's skin S is as close to the light source as possible. However, “12.5 mm” here does not necessarily mean the substantial distance JL. If the customer's skin S is flat, the actual distance JL is equal to or longer than the irradiation distance SL or the appropriate distance AL (12.5 mm or more), but the customer's skin S is uneven and the human meat is easily deformed. Therefore, the substantial distance JL may be shorter than the appropriate distance AL. Conventionally, since the appropriate distance AL is equal to the irradiation distance SL, for example, when human meat bulges or sinks inside the irradiation window 106 during the treatment, the substantial distance JL is about 9.5 mm or more 12. Less than 5 mm, shorter than the appropriate distance AL. For this reason, there is a problem that the skin S of the customer is placed at “under a temperature that may induce pigmentation”.

  Further, a reflector 107 is provided on the back side of the light emitter 103. The reflector 107 reflects heat. Therefore, when the customer's skin S just enters the position when the focal point of the heat reflection exists between the forefront of the irradiation window 106 and the irradiation filter 105, the temperature of the customer's skin S becomes excessively high. However, there is a problem of further increasing the “probability of inducing pigmentation”. Furthermore, when it gets worse, the customer's skin S may come into direct contact with the protective glass 104 and the irradiation filter 105. When the customer's skin S is in direct contact with the glass, there is a problem that pigmentation always occurs.

  Therefore, when the practitioner performs the correct treatment with the proper real distance JL (the real distance JL ≧ the proper distance AL) according to the manual, the customer's skin S does not take an excessive burden. However, if the practitioner ignores the manual and performs the wrong treatment at an inappropriate real distance JL (real distance JL <appropriate distance AL), the customer's skin S may “provide pigmentation. There is a problem that the customer's skin S is exposed to an excessive burden and causes pigmentation.

  In particular, the conventional air-cooled optical hair removal apparatus 100 is only sucked by a single air-cooled pump 108, so that the customer's skin S sticks to the irradiation window 106, and is easily entrapped inside. In addition to being easily exposed, there is a problem that the formation of an air flow of cooling air may be hindered.

This invention is made | formed in view of the said situation, The 1st objective can suppress the leakage of an ultraviolet-ray, and ensures the appropriate distance between a light source and a customer's skin reliably. Further, an object of the present invention is to provide an optical beauty device that can enhance the cooling effect.
A second object of the present invention is to provide a handpiece for an optical beauty device that can suppress leakage of ultraviolet rays and can ensure a proper distance between a light source and a customer's skin. It is in.

The inventor considered that the closer the illuminant is to the customer's skin, the higher the hair removal effect. However, as a result of diligent research, the present inventor can secure a certain amount of light energy, even if “the illuminant is separated from the customer's skin”, “when the illuminant is brought close to the customer's skin”. It has been found that the same hair removal effect can be obtained. The present invention has been completed based on this finding.
In order to solve the above-described problems, the optical beauty equipment used for hair removal / facial treatment and other cosmetic treatments according to the present invention is mixed with a light source and a component that absorbs or cuts ultraviolet rays of the irradiated light emitted from the light source. A light emitting means comprising the quartz glass, a radiation window attached to the front side of the light emitting means, and a passage forming means for forming a cooling air passage for the cooling air, wherein the cooling air inlet and A passage forming means in which an air outlet is formed, a mounting hole for attaching the irradiation window, an inflow hole for allowing outside air to flow into the cooling air passage, and a suction tube in the suction opening A suction pump that communicates with the air outlet, and a blow pump that communicates with the air outlet via a blow-out tube, and the irradiation between the forefront of the light emitting means and the end face of the irradiation window Release is characterized in that it is 16Mm～25mm.

  In the optical beauty device having the above-described configuration, when the irradiation light is irradiated from the light source, the light emitting means absorbs or cuts the ultraviolet rays by the component mixed with the quartz glass. Therefore, the light emitting means absorbs or cuts ultraviolet rays.

  The irradiation light cut by the ultraviolet rays is applied to the customer's skin, and an irradiation window is attached to the front side of the light emitting means. At this time, the irradiation distance between the forefront surface of the light emitting means and the end surface of the irradiation window is 16 mm to 25 mm. Therefore, if the skin is flat, a distance of 16 mm or more is always ensured between the light source and the skin. Even if the skin is curved and bulges to the light source side, or even if human flesh digs into the light source side, an appropriate distance that is the minimum distance that should be secured between the front surface of the light emitting means and the customer's skin As a minimum, a distance larger than 12.5 mm, which has been conventionally regarded as an irradiation distance, is always ensured. Accordingly, there is no pigmentation or redness on the customer's skin.

  Moreover, the operation | movement of a suction pump and a blowing pump starts with the driving | operation start of the optical beauty equipment including the irradiation start. These pumps only need to have a capacity of 100 to 200 liters / minute. The suction pump sucks air (including external air incidentally leaking from the inflow hole) existing in the cooling air passage from the suction port through the suction tube. As a result, an air flow is formed in the cooling air passage. In order to make this air flow smooth, in addition to the operation of this suction pump, clean air that does not mix dust and dirt is sent from the blowout outlet to the cooling air passage through the blowout tube. Thus, air is sucked from the suction port, and air is blown out from the blower outlet. Therefore, a smooth air flow from the air outlet to the air inlet is formed in the cooling air passage. For this reason, the temperature rise around a customer's skin is suppressed. Conventionally, only the suction pump is provided. However, in this case, the skin may be brought into close contact with the irradiation window, and the skin may bite, and the air flow may not be formed smoothly. In the present invention, by providing the blowout pump, it is possible to prevent excessive skin contact and form a smooth air flow.

  In addition, optical beauty devices turn body hair into ash in an instant and suppress its regeneration, but this reacts to “black objects” to make them ash in an instant and suppresses their regeneration. Is due to. Therefore, a frame body in which an attachment hole for attaching the irradiation window and an inflow hole for allowing outside air to flow into the cooling air passage is provided, and the outside air is consciously provided inside the handpiece, that is, the cooling air. Let it flow into the passage. "Regeneration-suppressed body hair" (meaning to include both body hair that has become ash that cannot be regenerated by hair removal treatment, and hair that remains in the skin and grows, takes time to regenerate) However, here, a part of the hair turned into ash is collected through a dust filter (not shown) provided in the apparatus main body through the inflow hole. Therefore, the air flow has not only cooling but also a function of removing “regeneration-suppressed body hair” (ash hair).

  In order to solve the above-mentioned problems, the handpiece of an optical beauty machine used for hair removal / facial treatment and other beauty treatments according to the present invention absorbs or cuts ultraviolet rays among light sources and irradiation light emitted from the light sources. A light emitting means comprising quartz glass mixed with a component, an irradiation window attached to the front side of the light emitting means, and a passage forming means for forming a cooling air passage for cooling air, wherein the cooling air A passage in which a suction port and an air outlet are formed; a frame in which a mounting hole for mounting the irradiation window; an inflow hole for allowing outside air to flow into the cooling air passage; and the suction port A suction tube connected to the air outlet, and an outlet tube connected to the air outlet, and an irradiation distance between the forefront of the light emitting means and the end face of the irradiation window is 16 mm to 25 m. It is characterized in that it.

  An optical beauty device and a handpiece thereof according to the present invention include a light source and a light emitting means including a quartz glass mixed with a component that absorbs or cuts ultraviolet rays among irradiation light irradiated from the light source. Therefore, there is an effect that ultraviolet ray leakage can be suppressed.

  Moreover, the optical beauty apparatus and its handpiece according to the present invention have an irradiation window attached to the front side of the light emitting means, and the irradiation distance between the front surface of the light emitting means and the end face of the irradiation window is 16 mm to 25 mm. Thus, there is an effect that an appropriate distance between the light source and the customer's skin can be secured. As a result, pigmentation and redness of the customer's skin can be reliably avoided, and there is an effect that safety is improved.

  Further, the optical beauty device according to the present invention is a passage forming means for forming a cooling air passage for cooling air, the passage forming means having the cooling air suction port and the air outlet formed therein, and the irradiation A frame formed with a mounting hole for mounting a window, an inflow hole for allowing outside air to flow into the cooling air passage, a suction pump communicating with the suction port via a suction tube, and the outlet Therefore, there is an effect that the cooling air can smoothly flow through the cooling air passage and the cooling effect can be enhanced. In addition to ensuring an appropriate distance between the forefront of the light emitting means and the skin of the customer, the cooling effect is enhanced, so that the safety is further enhanced.

  From the above, the optical beauty device and its handpiece according to the present invention ensure an appropriate distance between the light source and the customer's skin even if the practitioner carelessly performs the wrong treatment method. Therefore, there is no possibility of inducing pigmentation or redness on the customer's skin. Therefore, the present invention can greatly enhance the safety in use of the optical beauty machine.

  Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing the overall configuration of an optical beauty device 1 according to an embodiment of the present invention. As shown in FIG. 1, the optical beauty device 1 is roughly composed of an apparatus main body 2 and a hand piece 3. As shown in FIG. 1, the handpiece 3 includes a light emitter 4, a protective glass 5, and an irradiation filter 6 (see FIG. 9, FIG. 9 shows a conventional example, but parts common to this embodiment are Reference is made as appropriate, the same applies hereinafter), an irradiation window 7, an air passage forming plate 8 (reflecting plate 8), and a housing member 9 (see FIG. 2). Moreover, the arrow in FIG. 1 shows the flow of the cooling air.

  As shown in FIG. 1, the apparatus main body 2 includes a suction pump 10, a blowout pump 11, a signal generator 12, and the like. The handpiece 3 and the apparatus main body 2 are connected to each other by a suction tube 13, a blow-out tube 14, a trigger wire 15, and a high-pressure wire 16 (16 a and 16 b). The hollow hose 17 (see FIG. 2) is penetrated. The suction pump 10 and the blowout pump 11 are for cooling the handpiece 3, the skin of the customer, and the surrounding area. The suction pump 10 communicates with the suction port 22 via the suction tube 13, and the blowout pump 11 communicates with the blowout port 23 via the blowout tube 14. The signal generator 12 mainly performs light emission control of the light emitter 4. The trigger line 15 transmits a signal generated by the signal generator 12 to the light emitter 4 and other parts of the apparatus. The high voltage line 16 applies a voltage necessary for light emission of the light emitting unit 4.

  The device main body 2 further includes a touch panel 29 for selecting a beauty menu and various settings, a ROM 30 storing a program for starting the device main body 2 and causing it to function as a hair removal / facial beauty device and other beauty devices, and customer beauty processing A RAM 31 for storing a history or temporarily storing operation data during operation, and a CPU 28 for reading out a program from the ROM 30 and exchanging control signals with each part of the apparatus to control each part of the apparatus. Moreover, although illustration is abbreviate | omitted, the apparatus main body 2 is further provided with a power supply unit, a voltage conversion unit, a cooling fan, etc.

  Next, with reference to FIG.2 and FIG.3, the structure of the handpiece 3 is demonstrated in detail. FIG. 2 shows the internal structure of the handpiece 3. FIGS. 3A and 3B show the front view of the handpiece 3, where (a) the irradiation window 7 is attached and (b) the irradiation window 7 is removed. In these drawings, the light emitter 4 is formed of a U-shaped xenon lamp, and receives a control signal from the signal generator 12 to continuously emit light by operating the switch 26 every 20 seconds in a maximum speed of 1 second. it can. The illuminant 4 is made of quartz glass (for example, having a quality called Q3) mixed with a component that absorbs or cuts ultraviolet rays of the irradiated light. The quartz glass has a metal wire 18 wound around the surface, and the metal wire 18 is a copper wire, which makes the luminous body 4 shine. Irradiation light is thermally converted when it hits the black color of the hair removal site or the face to be treated, and the body hair is turned into ash in an instant, and its regeneration is suppressed in an instant.

  4A and 4B show the appearance of the irradiation window 7, and are an (a) front view, (b) side view, (c) top view, and (d) rear view. The irradiation window 7 is attached to the front surface side of the light emitter 4, and includes a window frame 19 having a thickness TH of 7 mm, and attachment pieces 20, 20... For attaching the frame 19 to the housing member 9. Consists of. The mounting pieces 20, 20... Are fitted into the multifunctional holes 21 (21a or 21b, see FIG. 3) of the housing member 9. Thereby, the irradiation window 7 is attached.

Here, the irradiation power P of the light emitter 4 (actual irradiation power P irradiated to the customer's skin S) will be described. The irradiation power P can be changed from 18 to 40 J (Jay) to 0.5 J (Jay). Here, J (Jay) is a unique unit system. For example, 24J (Jay) corresponds to 5 fluence (= Joule / cm ² ). Irradiation power P is affected not only by light emission energy but also by cooling control and irradiation distance. If the cooling control is constant (suction pump 10 is 98 liters / minute, blowout pump 11 is 38 liters / minute), The relationship between the irradiation power P irradiated to the customer's skin S and the irradiation distance SL is as shown in Table 1.

  FIG. 5 is a diagram showing the relationship between the irradiation distance SL, the appropriate distance AL, and the substantial distance JL when the irradiation window 7 is attached. The meaning of these terms is as described above, but will be described again. “Irradiation distance SL” refers to the distance between the forefront surface of the light emitter 4 and the end surface of the irradiation window 7. The “appropriate distance AL” refers to the minimum distance that should be ensured between the forefront of the light emitter 4 and the skin S of the customer. “Real distance JL” refers to the actual distance between the forefront of the light emitter 4 and the skin S of the customer. The irradiation window 7 is irradiated with light in contact with the customer's skin S, and functions to fix the irradiation position of the light emitter 4.

  In the present embodiment, the irradiation distance SL is 17.5 mm, and the breakdown is 7 mm from the window thickness TH (see FIG. 4), from the front surface of the light emitter 4 to the end surface of the casing 24 (see FIG. 2). The distance is 10.5 mm. However, the irradiation distance SL is not limited to 17.5 mm, and can be appropriately changed between 16 mm ≦ irradiation distance SL ≦ 25 mm. The reason will be described.

  If the irradiation distance SL is less than 16 mm, the customer's skin S may come into contact with the irradiation filter 6 in the worst case when the customer's skin S is absorbed. In addition, the actual distance JL is shorter than the minimum value (conventional irradiation distance SL) of 12.5 mm as the appropriate distance AL, and the customer's skin S is placed at “at a temperature that may induce pigmentation”. There is a fear. For these reasons, the irradiation distance SL is set to 16 mm or more.

  On the other hand, the reason why the irradiation distance SL is set to 25 mm or less is that if the irradiation distance SL is exceeded, the hair removal effect decreases unless the irradiation power P is increased and the powerful pumps 10 and 11 having high cooling ability are used. As the irradiation power P, it is desired to secure a fluence of about 4.0 to 5.0. In a beauty salon, 24J (Jay) is the most used, but in some cases, there is a possibility of use up to about 28J (Jay). As shown in Table 1, when the irradiation distance SL is 25 mm, 5.0 fluence can be secured at 28 J (Jay). Therefore, the upper limit of the irradiation distance SL is 25 mm.

  As long as the irradiation distance SL is 16 mm or more and 25 mm or less, the thickness TH may be any thickness. Considering that the customer's skin S sinks or bulges inside the irradiation window 7 as shown in FIG. 5B, the thickness TH is not applied to the irradiation filter 6 even if the customer's skin S bulges. A thickness that does not hit is required at least. If the irradiation distance is set to 16 mm or more and 25 mm or less, even if the practitioner makes a mistake in the treatment method, the customer's skin S will not be placed under “a temperature at which pigmentation may be induced”. Conventionally, if the usage method is wrong, there is a risk of being placed at that temperature, but in the present invention, there is no such risk.

  The air passage forming plate 8 is an aluminum metal plate provided in a U shape around the light emitter 4 (side and back surfaces) with the irradiation surface side open. A corrugated aluminum metal reflector (not shown) is attached to the irradiation surface side of the middle plate sandwiched between the side plates of the air passage forming plate 8. Strictly speaking, the metal reflector is a separate member from the air passage forming plate 8, but in the present embodiment, the metal reflector is referred to as the air passage forming plate 8 including the reflector. A cooling air passage R (see arrows in FIGS. 6 and 1) serving as a cooling air flow path is a space formed by the light emitter 4 and the air passage forming plate 8 (and the corrugated reflector).

  In order for the cooling air to flow in the cooling air passage R, an inlet / outlet of the air is required. Therefore, the air passage forming plate 8 is formed with the cooling air suction port 22 and the air outlet 23 (see FIGS. 1, 2, and 6). The suction port 22 is formed near the back surface of the U-shaped tip portion of the light emitter 4, and the air outlet 23 is formed near the back surface of the U-shaped lower end portion of the light emitter 4. The suction port 22 is attached with a suction tube 13 and communicates with the suction pump 10 via the suction tube 13. In the present embodiment, the suction pump 10 having a suction force of 120 liters / minute is used, and the actual suction force achieved thereby is 98 liters / minute. Moreover, the blower outlet 23 is attached with a blower tube 14 and communicates with the blower pump 11 through the blower tube 14. In the present embodiment, the blow pump 11 having a blow output of 120 liters / minute is used, and the actual blow output achieved by this is 38 liters / minute.

  FIG. 6 schematically shows the air flow of the cooling air during the hair removal of the optical beauty device 1. The air passage forming plate 8 is provided with a suction port 22 and a blow-out port 23, which are connected to the suction pump 10 and the blow-out pump 11, respectively, so that the air flow in the direction shown in FIG. Can be generated automatically. As a result, the temperature rise of the handpiece 3 held by the skin of the customer or the practitioner can be suppressed. Therefore, there is an effect of increasing the safety of customers and practitioners.

  Next, the housing member 9 shown in FIG. 2 houses the light emitting body 4, the protective glass 5, the irradiation filter 6, the irradiation window 7, the air passage forming plate 8, and a circuit board (not shown), and is made of a polymer resin. Made of an insulator. The reason why the housing member 9 is made of a polymer resin insulator is to prevent the housing member 9 from being burned by heat generated by the light emitter 4. The housing member 9 is naturally disposed inside the handpiece housing 24. As shown in FIG. 3B, the irradiation surface side of the housing member 9 is open (actually the protective glass 5 and the irradiation filter 6 are present but transparent), and in the space behind the opening. The air passage forming plate 8 and the light emitter 4 are accommodated. The opening end surface of the housing member 9 has an appearance like a frame having almost the same size as the irradiation window 7, a mounting hole 21 a (multifunctional hole 21) for mounting the mounting piece 20 of the irradiation window 7, and the outside air as cooling air An inflow hole 21b (multifunctional hole 21) for flowing into the passage R is formed.

  The attachment hole 21a and the inflow hole 21b have the same shape and size. Depending on the position of the attachment piece 20, the attachment hole 21a becomes the inflow hole 21b and vice versa. Further, the handpiece 3 has a structure in which outside air flows into the inside of the handpiece housing 24, specifically, the cooling air passage R from the gap of the mounting hole 21a even when the mounting piece 20 is mounted in the mounting hole 21a. It has become. Further, due to the influence of the airflow flowing in the cooling air passage R (see FIG. 6), a gap formed between the irradiation window 7 and the handpiece housing 24, between the handpiece housing 24 and the housing member 9. Intake air is also taken from the gaps, the gaps through the inflow holes 21b and the attachment holes 21a to the back side of the housing member 9, and introduced into the cooling air passage R. By these air flow and intake air, air heated to high temperature by irradiation light and dust in the atmosphere are sucked. And the heat increase of the handpiece 3 is suppressed. Furthermore, the unpleasant odor of the hair removal site or the face to be cleaned is deodorized by the air filter (not shown) of the apparatus body 2.

  The configuration of the handpiece 3 will be further described. A filter inlet 32 (see FIG. 9) is formed in a slit shape on the upper surface of the handpiece housing 24. The filter inlet 32 is a hole that serves as an inlet or an outlet for attaching and detaching the irradiation filter 6. The filter loading inlet 32 communicates with a filter loading groove (not shown) in which the irradiation filter 6 is loaded. The filter insertion groove (not shown) has a U-shaped cross section or U-shaped front view, and is formed in the front side of the protective glass 5. A transparent uncolored glass protective glass 5 is provided on the front surface of the light emitter 4. When the irradiation filter 6 is attached, the protective glass 5 and the irradiation filter 6 often overlap with a gap. A metal protective plate 33 made of aluminum is provided so as to surround the narrow edges of the protective glass 5 and the irradiation filter 6. This is to protect the housing member 9 and the handpiece housing 24 from heat.

  The handpiece casing 24 is manufactured by molding a polymer resin material. The handpiece housing 24 is a combination of two molded products. The grip 25 of the handpiece casing 24 is a place where the practitioner performs a hair removal / facial treatment or other beauty treatment. In addition, a switch 26 is provided inside the handpiece housing 24, which protrudes to a position where the surface can be easily operated. Further, a thermistor 27 for performing temperature detection for performing cooling control is provided.

  The switch 26 is connected to the CPU 28 of the apparatus main body 2 by a shielded wire passed through the hollow hose 17. When the CPU 28 detects the operation of the switch 26, the CPU 28 sends a command necessary for causing the light emitter 4 to emit light to each part of the apparatus.

  In the optical beauty device 1 having such a configuration, the signal generator 12 converts the power supplied from the power source into high voltage power, and generates a signal having a length of 20 msec once a second according to control from the CPU 28. Then, the signal causes the light emitter 4 to emit light according to the on / off operation of the switch 26 of the handpiece 3, and the irradiation light that has passed through the irradiation filter 6 is irradiated to the hair removal site or the face to be treated. Thereby, desired cosmetic processing is performed.

  During this time, an air flow is formed in the cooling air passage R by the operation of the suction pump 10 and the blowout pump 11, and a gap between the irradiation window 7 provided on the front surface of the handpiece 3 and the handpiece housing 24, and the like. Dust-like tissue and high-temperature air destroyed by the cosmetic treatment are sucked from the gap. The dust sucked in high-temperature air is stored in a dust filter (not shown). This prevents overheating of the irradiated part and the handpiece 3, and the dust remaining on the hair removal part and the face part to be removed.

Next, the operation of the optical beauty device 1 will be described. The practitioner attaches the irradiation filter 6 to the handpiece 3 in accordance with the purpose (hair removal / beauty face or other beauty treatment). For the hair removal, a red coloring component 6 is deposited and a red irradiation filter 6 that transmits light having a wavelength of 600 nm to 1200 nm is used. In addition, a yellow coloring component is vapor-deposited for a beautiful face, and a yellow irradiation filter 6 that transmits light having a wavelength of 520 nm to 1200 nm is used. For the acne skin, a blue coloring component is deposited, and a blue irradiation filter 6 that transmits light having a wavelength of 400 nm to 520 nm is used.
Next, the practitioner turns on the switch 26 of the apparatus main body 2 to display the start screen of FIG. The practitioner can select and press the “START” button and the “SERVICE” button.

  When the “START” button is pressed, the skin mode screen shown in FIG. Here, the type of beauty treatment and the skin quality can be selected. “Red filter” corresponds to hair removal treatment, “yellow filter” corresponds to facial treatment, and “blue filter” corresponds to acne treatment. When the “NEXT” button is pressed after the beauty processing type and skin quality are selected, the CPU 28 issues a control command to each part of the apparatus in accordance with the pressed information. In each part of the apparatus, processing and setting are performed in accordance with instructions from the CPU 28.

  Next, the irradiation mode screen of FIG. 7C is displayed on the touch panel. Here, the irradiation mode can be selected. The irradiation mode indicates how many times the irradiation is performed with the irradiation power P of the set value, and corresponds to an irradiation process in which the “single pulse” button performs irradiation with the irradiation power P of the setting value once. The “SET1”, “SET2”, and “SET3” buttons correspond to irradiation processes in which irradiation is performed in three, four, and five times with the irradiation power P of the set value, respectively. In the column “number of customer irradiations”, the number of customer irradiations (not the total number) at that time is displayed. A new customer can be reset by pressing. If you are in the middle of a beauty treatment for the same customer, you can leave it without resetting. Here, when any one of the buttons is pressed, the CPU 28 issues a control command to each part of the apparatus according to the pressed information. In each part of the apparatus, processing and setting are performed in accordance with instructions from the CPU 28.

  When the practitioner presses the “START” button in the state of FIG. 7C, the operation screen of FIG. 7D is displayed on the touch panel. Then, when the practitioner presses the switch 26, irradiation starts in the state of the screen of FIG. When the illuminator 4 is irradiated with irradiation light, the quartz glass absorbs or cuts the ultraviolet rays by the mixed ultraviolet cut component. Since the ultraviolet cut component is not vapor-deposited on the quartz glass surface, the ultraviolet cut component does not peel off, and the light emitter 4 can be used for a long time.

  Although the irradiation light cut by the ultraviolet rays is irradiated on the skin S of the customer, according to the present embodiment, an irradiation distance SL of 16 mm or more and 25 mm or less is secured. Therefore, according to the present embodiment, even if the skin is curved and bulges to the light emitter 4 side or human flesh is sunk to the light source side, the actual irradiation distance SL (= conventional irradiation distance SL) A distance of 12.5 mm or more, which is an appropriate distance AL), is secured. Therefore, even when there is a slight increase in temperature due to the heat of irradiation, irradiation at “under a temperature that may induce pigmentation” can be suppressed. Therefore, even if the practitioner performs a wrong treatment method, the safety of the customer's skin S is ensured.

  Moreover, the operation | movement of the suction pump 10 and the blowing pump 11 starts with the start of irradiation. These pumps have a capacity of 120 liters / minute, but are not limited thereto. The suction pump 10 sucks air (including external air incidentally leaking from the inflow hole 21 b) existing in the cooling air passage R through the suction tube 13. As a result, an air flow is formed in the cooling air passage R from the lower side of the light emitter 4 toward the upper side (U-shaped curved tip) (see FIG. 6). In order to enhance the cooling effect and the absorption effect by the air flow, in addition to the operation of the suction pump 10, clean air that does not mix dust and dirt is discharged from the outlet 23 by the outlet pump 11 through the outlet tube 14. It is fed into the cooling air passage R. As a result, air is sucked from the suction port 22, and air is blown out from the blower outlet 23. Accordingly, an appropriate air flow from the air outlet 23 toward the air inlet 22 is formed in the cooling air passage R. For this reason, the temperature rise around a customer's skin is suppressed. In the past, only the suction pump 10 was provided. However, in this case, the skin may be brought into close contact with the irradiation window 7 (in short, the state where the customer's skin S is sucked into the irradiation window 7). By providing the blowout pump 11, excessive skin contact can be prevented.

  Further, due to the influence of the cooling air flow, the outside air also flows into the cooling air passage R from the mounting hole 21 a for attaching the irradiation window 7 and the inflow hole 21 b for allowing the outside air to flow into the cooling air passage R. “Regeneration-suppressed body hair” (ash body hair) and dust in the outside air enter the cooling air passage R through the inflow holes 21b and other gaps of each part of the apparatus, and the apparatus through the suction tube 13 Collected by a dust filter (not shown) provided in the main body 2. Therefore, the cooling air flow contributes not only to cooling but also to removing “regeneration-suppressed body hair” (ash body hair).

  Further, the practitioner can change the irradiation power P in a state where the operation screen of FIG. 7D is displayed (during irradiation), for example, a “power up” button and a “power down” button. The irradiation power P can be set by pressing the button. Specifically, as described above, the irradiation level can be changed from 18 to 40 J (Jay) every 0.5 J (Jay). At this time, the items set in the skin mode screen of FIG. 7B and the irradiation mode screen of FIG. 7C are displayed in the “filter type” column, “skin quality” column, and “irradiation method” column. Is displayed. Therefore, it is possible to work while confirming these. The CPU 28 issues a control command to each part of the apparatus according to the pressed numerical value. In each part of the apparatus, processing and setting are performed in accordance with instructions from the CPU 28.

  When the “SERVICE” button is pressed on the start screen of FIG. 7A, the service screen of FIG. 7E is displayed. In the “total number of irradiations” column, the total number of irradiations from the start of use of the optical beauty device 1 to the present time is displayed, and the total number of irradiations emitted is displayed regardless of the irradiation power. The replacement time of the irradiation filter 6 of the optical beauty apparatus 1 is about 20,000 total irradiations, but the replacement time can be known by checking the total number of irradiations. In the “total number of red irradiations”, “total number of yellow irradiations”, and “total number of blue irradiations” fields, the total number of irradiations from the start of use of the optical beauty device 1 to the present time when the irradiation filters 6 of the respective colors are used. Is displayed. Further, the “lightness adjustment” button can be pressed to adjust the contrast of the touch panel 29. The CPU 28 issues a control command to each part of the apparatus according to the pressed information. In each part of the apparatus, processing and setting are performed in accordance with instructions from the CPU 28.
