As shown in FIG. 2, the control unit 7 of the apparatus main body 2 includes an irradiation control unit 16, an operation control unit 17, a timer 18, and the like. The irradiation control unit 16 operates the irradiation unit 20 based on the operation of the first handpiece 3A or the second handpiece 3B to cause the xenon tube 21 to emit light, and irradiates a light beam through the irradiation window 22 opened in a rectangular shape. To control. The irradiation window 22 is constituted by a light guide tube made of sapphire, and its size is, for example, 1.8 cm × 4.5 cm.

Control.

  As shown in FIG. 2, the cooling unit 8 cools the heat generated by the light emission of the xenon tubes 21 provided in the first handpiece 3A and the second handpiece 3B with cooling water. Further, the cooling unit 8 cools the irradiation window 22 of the irradiation unit 20 together with the cooling of the xenon tube 21 to prevent the generation of burns caused by irradiating the skin surface with light rays. The cooling unit 8 includes a cooling water tank 26 that supplies and stores cooling water, a water pump 27 that sends cooling water, and the like. In the cooling water tank 26, for example, a pipe is wound in a coil shape, and a chiller unit 26A that cools the cooling water by passing a cooling gas through the pipe is provided.

  The chiller unit 26A is provided in the cooling water tank 26 and cools water in the cooling water tank 26. The water cooled in the cooling water tank 26 is circulated through a cooling water pipe 28 by a water supply pump 27, and the xenon tube 21 provided in the irradiation unit 20 of the first handpiece 3A and the second handpiece 3B and the irradiation light. The window 22 is cooled. The cooling water tank 26 is provided with a water flow sensor 29 for detecting cooling water flowing inside the cooling water tank 26.

  As shown in FIG. 3, the cooling water pipe 28 is connected via a connection pipe 31 that directly connects the cooling water tank 26 and the water supply pump 27 and a first handpiece 3A and a second handpiece 3B. A cooling water pipe 32 connects between the cooling water tank 26 and the water supply pump 27. The cooling water pipe 32 is bifurcated in the middle of the circuit and has a first branch portion 32A and a second branch portion 32B. The two branch portions 32A and 32B are connected at one end to form a single branch. And returned to the cooling water tank 26 via the filter 33. The cooling water pipe 32 and the connection pipe 31 constitute a circulation pipe 30 that communicates the cooling unit 8 with the first handpiece 3A and the second handpiece 3B.

  The first branch portion 32A of the cooling water pipe 32 is introduced into the first handpiece 3A, so that the xenon tube 21, the irradiation window 22, and the like inside the first handpiece 3A can be cooled. I have. At the tip of the first handpiece 3A, a rectangular parallelepiped hollow portion 24 is provided, into which a xenon tube 21 as an irradiation lamp and a cassette 20 as an irradiation unit equipped with an irradiation window 22 are fitted. An irradiation window 22 is opened at the exit side of the cassette 20, and ultraviolet rays are cut by a light guide tube made of sapphire, and light aligned in a direction perpendicular to the irradiation window 22 is formed by the action of a reflector behind the xenon tube 21. Irradiated. The xenon tube 21 is partitioned by a partition plate such as a metal plate having a high thermal conductivity around the recess 24 so that the xenon tube 21 does not come into contact with the cooling water, and the cassette 20 is cooled by the cooling water from three directions around the partition plate. ing.

Further, a Peltier element 25 is provided on a partition plate between the cassette 20 and the cooling water, and the heat of the xenon tube 21 flows into the cooling water. The Peltier device 25 is a thermoelectric device utilizing the Peltier effect. By incorporating the Peltier device in a handpiece, the Peltier device 25 not only reduces a temperature rise due to irradiation heat, but also realizes a comfortable and cold feeling to the skin. In this way, the xenon tube 21 and the irradiation window 22 inside the first handpiece 3A are efficiently cooled by using the Peltier element 25 and the chiller unit 26A. Similarly, the second branch portion 32B of the cooling water pipe 32 is introduced into the inside of the second handpiece 3B, and similarly, the dent portion 24 serves as an irradiation portion having the xenon tube 21 and the irradiation window 22 mounted thereon. The cassette 20 is fitted therein, and a Peltier element 25 is used, whereby the xenon tube 21 and the irradiation window 22 inside the second handpiece 3B can be efficiently cooled. Thus, the water pump 27 is operated to flow the cooling water into the cooling water pipe 32, so that the xenon tubes 21 and the irradiation windows 22 of the two handpieces 3A and 3B are always cooled simultaneously.

  As shown in FIG. 1, two piece receiving portions 35 arranged so as to sandwich the operation panel 14 are provided on the upper front part of the casing 5 of the apparatus main body 2. The first handpiece 3A and the second handpiece 3B are individually and detachably held by these piece receiving portions 35.

  As shown in FIGS. 1 and 2, the two handpieces 3A and 3B have the same structure and the same performance, and include a handpiece body 37, an irradiation unit 20, a xenon tube 21, an irradiation window 22, It comprises a display 23, an irradiation button 40, an irradiation counter 41 and the like. The handpieces 3A and 3B are operated by grasping the grip portion or the main body portion by hand and causing the irradiation unit 20 to face a part for performing hair removal processing. Each handpiece 3A, 3B is connected to the apparatus main body 2 via a connection cable 4. That is, one end of each of the two connection cables 4 is connected to one end of each of the hand pieces 3A and 3B, and the other end of each of the connection cables 4 is connected to the connection unit 43 provided on the front of the apparatus main body 2 via the connection connector 42. It is connected to the.

  The cooling water supplied to the first handpiece 3A and the second handpiece 3B circulates in the chamber, converts heat between the cooling water and the xenon pipe 21, and returns to the cooling water tank 26. The cooling in the cooling water tank 26 uses a chiller unit 26A, and cools the purified water in the cooling water tank 26 by, for example, passing a refrigerant (gas) through a pipe wound in a coil shape. By controlling the output of the first handpiece 3A and the second handpiece 3B, the first handpiece 3A and the second handpiece 3B can be used as a hair removal treatment device for a human body, and can also be used as a hair removal treatment device for a face. Alternatively, two types of handpieces having different outputs may be prepared in advance, and the handpieces may be replaced according to purpose.

When using a handpiece that irradiates a frequency region (around 530 nm) called a photo facial, it is possible to automatically determine only the handpiece replacement operation without the need to replace the device body 2. In this regard, a memory chip having a predetermined function is mounted inside the photofacial handpiece, and a special signal is transmitted from the memory chip when the handpiece is connected to the main body of the apparatus, so that it is automatically generated. The type of the handpiece can be identified. As a result, the difference between the hair removal handpiece (around 630 nm) and the photofacial handpiece (around 530 nm) can be identified without exchanging the apparatus main body, and automatic recognition becomes possible. Thus, a plurality of types of handpieces having different wavelengths and outputs of irradiation light can be exchanged with one touch. In this case, the control circuit may be switched according to the type of the handpiece, or the control parameters may be changed by one control circuit.

  FIG. 4A is a diagram showing an example in which an output waveform by ultra-high-speed photo epilation (SHR method) according to the present invention is compared with a waveform by conventional photo epilation, and reference numeral 61 denotes an output by the conventional method. Reference numeral 62 denotes an output waveform obtained by ultra-high-speed photo epilation (SHR method). The mechanism based on ultra-high-speed photo epilation (SHR method) uses a heat storage method that instantaneously emits weak output and accumulates energy, and performs treatment to slide the crystal on the skin surface. It is. Therefore, the treatment time can be significantly reduced, and the burden on the skin can be suppressed, so that the hair can be surely removed without the risk of skin trouble.

  As for the output pulse of the conventional photoepilation device, the output of the pulse is attenuated with the passage of time. The second pulse has a lower output (eg, 90%) than the first pulse, and the third pulse has a lower output. Then, if the pulse is output continuously several times, the output becomes unsuitable for use. Then, it takes time for charging to generate the pulse, and a time loss occurs.

  The control unit 7 according to the present embodiment includes a capacitor capable of holding a large output, a unit that divides one pulse into a plurality of small pulses, a unit that connects the divided small pulses to form a combined pulse, Means for preventing the pulse from attenuating with the passage of time, thereby enabling stable light emission. That is, it has a capacitor capable of holding a large output so as to generate a large output when generating a pulse. For example, two large-capacity electrolytic capacitors (19000 MFD / 450 VDC) are provided. That is, the ability to output a sufficient output is maintained. Then, one pulse is divided into a plurality of small pulses. Further, a plurality of small pulses are collected and connected to form a composite pulse. For example, if five small pulses are connected first, then six small pulses are connected, and then seven small pulses are connected, a constant output will be maintained even if the pulse output gradually decreases. Can be formed. In this way, a pulse whose output is stable can be formed by continuous pulses.

  Further, in order to prevent the synthesized pulse from attenuating with time, there is provided a means for monitoring the state of charge of the capacitor and the output of a large pulse and calculating the number of pulses to be connected. Then, the calculated number of pulses is provided to means for collecting and connecting a plurality of small pulses to form a composite pulse. As a result, connected synthesized pulses are generated at equal intervals, and a pulse whose output is stable for a long time can be formed.

  FIG. 4B shows an example of an output measurement result by the ultrafast photo epilation (SHR method) according to the present invention. The light emission intensity (level) can be set by the [LEVEL] icon displayed on the operation panel 14. The range of LEVEL is 20 levels from LEVEL01 to LEVEL20, and the strongest level is LEVEL20. The numerical values shown in FIG. 5 indicate the set voltage and the measured voltage from LEVEL01 to LEVEL20, and the target value (J: joule) and measured value (J: joule) of the irradiation window 22.

  According to the operation panel 14 of the present embodiment, rapid cooling is possible, so that cooling is started at the same time when the power is turned on, and the temperature can be immediately reduced to 0 ° C. or less.

  The point that the photo epilation apparatus 1 according to the present embodiment is excellent is that cooling can be simultaneously performed on the two left and right handpieces 3A and 3B. For example, first, the treatment is performed with the first handpiece 3A, and if the user feels that the fire has been repeated and the temperature has increased, the treatment is continued by switching to the second handpiece 3B. Further, when the operation is continued with the second handpiece 3B, and if the user feels that the continuous fire has overlapped and the temperature has increased, the operation can be continued again by switching to the first handpiece 3A, and the operation can be performed without interruption. . Also, if an optional photo handle (hand piece) is attached to, for example, the second hand piece side, different treatments are performed as the first hand piece 3A is used for hair removal and the second hand piece 3B is used for photo work. Can be performed, and the range of treatment can be expanded.

  FIG. 5A is a perspective view illustrating an example of the handpiece 3 of the optical hair removal device 1 according to the present embodiment. The handpiece 3 is a generic name for the handpieces 3A and 3B. The handpiece 3 is configured to include the irradiation unit 20. The irradiating section 20 is a cassette type. An irradiating lamp (xenon tube) 21 and an optical waveguide component 50 are incorporated in a storage case 51, and are detachably attached to a cooling water hose 52 by a connecting fastener 53.

  FIG. 5B is a perspective view illustrating an example of the optical waveguide component 50 in the handpiece 3 of the optical hair removal apparatus according to the present embodiment. The optical waveguide component 50 is formed of, for example, a synthetic quartz, for example, in a rectangular parallelepiped shape, and light from the irradiation lamp 21 is introduced from an end surface on the irradiation lamp 21 side, and is reflected on a boundary surface while being opposite to the irradiation lamp 21. Is emitted from the end face. The six surfaces of the rectangular parallelepiped are designed to be optically polished so that light incident from the end face on the side of the irradiation lamp 21 is reflected on the side face and efficiently emitted from the end face on the side opposite to the irradiation lamp 21. The irradiation lamp 21 is stored on the bottom side of the storage case 51, and then the optical waveguide component 50 is stored so that the side surface of the storage case 51 is surrounded by and contacts the storage case 51. The storage case 51 is fitted into a concave hole (not shown) provided in the handpiece 3 in a cassette format. Then, inside the handpiece 3, cooling water is supplied to the outside of the concave hole from the cooling water hose 52, and the irradiation lamp 21 and the optical waveguide component 50 are cooled. The storage case 51 and the concave hole are made of, for example, a metal having high thermal conductivity in order to enhance the cooling effect.

As shown in FIG. 5B, the optical waveguide component 50 is configured in a rectangular parallelepiped shape, and is configured to have a rectangular parallelepiped shape in which sides or corners in contact with a human body are rounded. In FIG. 5B, two sides of the rectangular parallelepiped are configured to be round. The degree of roundness is, for example, 1 mmφ to 10 mmφ. The size of the optical waveguide component 50 changes according to the size of the irradiation lamp 21, and is, for example, 30 to 100 mm × 30 to 60 mm × 10 to 40 mm. The shape of the optical waveguide component 50 may be a substantially rectangular parallelepiped, for example, a trapezoid close to a rectangular parallelepiped, or a quadrangular pyramid.
Thereby, the handpiece 3 can be smoothly moved along the surface of the human body, and the risk of damaging the human body is eliminated. In addition, since the sides and corners of the rectangular parallelepiped are rounded, the light spreads at a wide angle, and the light can reliably be applied to the depressions of the human body. An electric cord is connected to the electrode of the irradiation lamp 21. For example, the electric cord is guided to the outside of the handpiece 3 from the vicinity of the cooling water supply port through the bottom of the storage case 51, cooling water, and the exterior of the handpiece 3. May be.

When the handpiece 3A (or 3B) scans in a zigzag manner and irradiates the light in a zigzag manner, the treatment time is shortened and an efficient hair removal process is performed. be able to. FIG. 7B illustrates a state in which a treatment is performed on the back of the body, and the handpiece 3A (or 3B) is similarly scanned in a zigzag manner.

  FIG. 8 illustrates a state of performing a treatment on the face. In this case, before the treatment, the eyes, eyebrows, and the hairline are covered with cotton 54 or the like, and goggles are placed thereon to protect the eyes. To do. In this treatment, the handpiece 3A (or 3B) does not scan in a zigzag manner, but instead divides the whole into a number of sections 55 and scans each section 55 in order.

  Returning now to FIG. 6B. Then, the process shifts to step S009 to end the light irradiation by the handpiece 3A (or 3B). Next, in step S010, the subject leaves the bed. Then, the process shifts to step S011 to input data on this treatment to the recording device, and ends the processing according to this flowchart. (The input data is better for later treatments, so it is better to input Sometimes not).

  9A and 9B show examples of the relationship between the number of treatments and the output of the handpiece 3A (or 3B). FIG. 9A shows a case where the skin is normal, and FIG. This shows the case of a subject who is weak and has a strong pigment.

As shown in FIG. 9A, in the case of a subject whose skin is normal,
Part 1 (a) It is preferable to set the output (LEVEL 1 to 20 shown in FIG. 5) as follows in accordance with the number of treatments at places where the hair is thick (armpit, below the elbow, below the knee, V line). That is, when the number of treatments is 1 to 3 times, LEVEL 6 to 8, when the number of treatments is 4 to 6 is LEVEL 9 to 10, and when the number of treatments is 7 to 12 is LEVEL 11 to 12.
Part 2 (b) It is preferable to set the output (LEVEL 1 to 20 shown in FIG. 5) in the following manner at the part of the hair growth (on the elbow, on the knee, the body, the back, the finger, and the neck) according to the number of treatments. . That is, when the number of treatments is 1 to 3 times, LEVELs 7 to 9, when the number of treatments is 4 to 6 is LEVEL 9 to 10, and when the number of treatments is 7 to 12 is LEVEL 11 to 13.

In addition, as shown in FIG. 9B, in the case of a subject whose skin is weak and the pigment is dark,
Part 1 (a) In places where the hair is thick (armpit, below the elbow, below the knee, below the V line), LEVEL6-7 when the number of treatments is 1-3, and LEVEL7-9 when the number of treatments is 4-6. When the number of treatments is 7 to 12, the level is set to LEVEL 9 to 10.
Part 2 (b) In the place of hair growth (on the elbow, above the knee, body, back, fingers, neck and leg), LEVEL7 to 9 when the number of treatments is 1 to 3 and LEVEL9 when the number of treatments is 4 to 6 When the number of treatments is 7 to 12, the level is set to LEVEL 11 to 12.

  According to the photo-epilation apparatus 1 according to the first embodiment of the present invention, since the double cooling mechanism provided with two depilation handpieces, two handpieces are always cooled, and at least one handpiece is always used. It can be maintained in a usable state. Therefore, during treatment, continuous treatment can be performed without waiting for cooling of the handpiece, and treatment can be performed in a shorter time.

  Further, according to the photo-epilation device 1 according to the second embodiment of the present invention, in a device capable of a continuous firing function (continuous light emission), the capacity of the capacitor is increased to increase the charging capability and the circuit configuration is devised. Since the addition is performed, a large output can be held, and the output attenuation during continuous emission can be suppressed. As a result, the same amount of heat is emitted regardless of the number of irradiations in the treatment during continuous firing, which prevents the phenomenon that the pulse output attenuates with the number of irradiations as in the past, and maintains a stable output. Therefore, a certain effect in the operation can be expected.

  According to the photo-epilation device 1 according to the third embodiment of the present invention, when using a handpiece that irradiates a frequency region (around 530 nm) called a photo facial, the device main body 2 needs to be replaced. Instead, the model can be automatically determined when the handpiece is replaced. Thus, a plurality of types of handpieces having different wavelengths and outputs of irradiation light can be exchanged with one touch. In this case, the control circuit may be switched according to the type of the handpiece, or the control parameters may be changed by one control circuit.

  As described above, the present invention is not limited to the above-described embodiment, and various modifications are possible within an equivalent range, and various modifications are possible within the scope of the invention described in the claims. That will be readily appreciated by those skilled in the art.
