Description

Light irradiation device for nail resin

The present invention relates to a nail resin curing light irradiation device that cures a nail gel applied to a nail with light.

Conventionally, in stores such as nail salons, a nail gel is applied to a customer's hand or toenail, and the nail gel is irradiated with light and cured on the spot. At this time, a nail resin curing light irradiation device (hereinafter referred to as a light irradiation device) is used (see, for example, Utility Model Registration No. 3042166).

The nail gel generally uses an ultraviolet curable resin, and is cured in a short time by irradiating ultraviolet rays from a light irradiation device. With the nail gel, the nail can be extended from the actual nail of the limb to the tip side.

There are various types of UV curable resins used in nail gels. There are hard gels that are mainly insoluble in solvents and soft gels that can be dissolved in solvents. In recent years, soft gels that can be dissolved in a solvent have become widespread, and ultraviolet rays having a wavelength of 405 nm are preferable in order to cure the soft gels. Therefore, an LED that can irradiate ultraviolet rays having a wavelength of 405 nm is mounted on the light irradiation device, and a technique for curing the soft gel in several tens of seconds has been proposed (see, for example, Utility Model Registration No. 3179777).

FIGS. 13A to 13D show a process of forming a nail using a nail gel in a nail salon. The manicurist wraps the expansion seal 110 around a fingertip without a nail (see FIG. 13A) (see FIG. 13B). The expansion seal 110 is wound in a cylindrical shape so that the tip side of the finger is further expanded.

The expansion seal 110 provides an extension surface 111 for applying nail gel. The expansion seal 110 has an opening 110A at a portion corresponding to the claw. As a result, by exposing the actual nail from the opening 110A, the extended surface 111 is connected to the nail. If a nail gel is simultaneously applied to the nail and the extended surface 111 and cured, the nail can be formed so as to continue from the actual nail. As described above, the expansion seal 110 functions as a nail gel holding member that temporarily holds the nail gel.

When the fingertip is inserted into the light irradiation device, the seal end 112 remaining on the ventral side of the finger of the expansion seal 110 becomes an obstacle. When the seal end 112 is caught by the light irradiation device, the extended surface 111 is deformed and the shape of the nail is distorted. Therefore, the manicurist cuts the seal end 112 in advance with scissors (see FIG. 13C).

Then, the manicurist applies gel nail to the extended surface 111 (see FIG. 13D), puts the fingertip in the light irradiation device, and irradiates ultraviolet rays to cure the gel nail on the spot. A nail having a desired size is formed while repeating this process.

However, the manicurist wants to avoid bringing the blade close to the customer's fingertip as much as possible in order to cut the seal end 112. In addition, for a manicurist who handles customers in a face-to-face manner, when the seal end 112 is cut with scissors, the tip of the scissors faces the customer side. Some customers may be afraid of cutting the seal end 112 with scissors.

Furthermore, since the bonding area of the expansion seal 110 is reduced by cutting the seal end portion 112, there is a problem that the expansion seal 110 is easily peeled off from the finger during the operation.

The present invention has been made in view of such circumstances, and intends to provide a highly convenient light irradiation device even when an expansion seal is used.

The above object is achieved by the following means based on the earnest research of the present inventors.

That is, a light irradiation device for curing a nail resin that achieves the above object includes a ventral cover member that opposes the belly of a fingertip, a nail cover member that is disposed so as to cover at least the nail of the fingertip, and light on the nail. A light source for irradiating the ventral cover member, wherein the ventral cover member is formed with an accommodating portion for accommodating a part of a nail resin holding member provided on the fingertip at least in the vicinity of the fingertip. .

In relation to the above object, the ventral cover member of the nail resin curing light irradiation device faces at least four belly of the fingertips, and the ventilating cover member has the accommodating portion, You may make it accommodate a part of said nail resin holding member of the said at least 4 said fingertip.

In relation to the above object, the storage portion of the nail resin curing light irradiation device may include a region narrower than the finger width of the fingertip.

In relation to the above object, the housing part of the nail resin curing light irradiation device may have a slit shape along the longitudinal direction of the fingertip.

In relation to the above-mentioned purpose, a protrusion that contacts the belly of the fingertip may be formed around the accommodating portion of the nail resin curing light irradiation device.

In relation to the object, the light source of the light irradiation device for curing the nail resin is disposed in the vicinity of an opposing light source that is disposed to face the nail and irradiates light on the surface of the nail, and an extension line of the finger. The fingertip side light source that emits light toward the fingertip may be provided.

In relation to the above object, a light absorbing surface that absorbs the light may be formed on the inner wall of the claw side cover member of the nail resin curing light irradiation device.

According to the present invention, even in an operation process using an expansion seal, the cutting operation of the expansion seal can be omitted, and the nail resin can be cured safely and reliably.

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

FIG. 1 shows the overall configuration of a nail resin curing light irradiation device (hereinafter referred to as a light irradiation device) 1 according to an embodiment of the present invention. 1A is a perspective view, and FIG. 1B is a cross-sectional view along the center line.

The light irradiation device 1 includes an upper housing 10, a lower housing 16, a finger placement table (abdominal cover member) 20, an inner cover (nail cover member) 30, an LED light source group 40, a wiring board 42, and a power supply device 50. A control device 60 and a power cable 70.

The upper housing 10 is formed in a dome shape so as to cover the entire upper part of the inserted limb. Specifically, the upper housing 42 has a ceiling portion 10A disposed above, left and right side portions 10B disposed on the side surfaces of the limbs, and a back portion 10C disposed in the distal direction of the limbs. The insertion port 10D opens on the side. An operation region 12 is formed on the upper surface of the ceiling portion 10A. This operation area 12 is directed to the opposite side of the user, and is operated by a manicurist facing the user. The operation area 12 includes a power button 12A, an auto setting button 12B, a 5 second setting button 12C, a 10 second setting button 12D, a 20 second setting button 12E, and a display screen 12F. These operation areas 12 are connected to the control device 60 and input / output various information.

The power button 12 </ b> A turns on / off the light irradiation device 1. The auto setting button 12B sets an operation mode (manual / automatic). The 5 seconds, 10 seconds, and 20 seconds setting buttons 12C, 12D, and 12E set the irradiation time of the LED light source group 40. The display screen 12F displays various data such as countdown, countup, setting mode, and error of irradiation time.

The extension plate 10E is slidably disposed on the inner side in the vicinity of the insertion port 10D of the ceiling portion 10A. The extension plate 10E extends to the user side by pulling the extension plate 10E to the user side. The extension plate 10E blocks the light of the internal LED light source 40, thereby reducing the amount reaching the user's eyes. A distance sensor 11 for measuring the distance to the obstacle below is disposed inside the ceiling portion 10A, and the distance to the finger placement table 20 is usually output. When a hand is inserted into the housing, the distance to the hand is output. Based on the change in the output value, it is detected whether or not a hand has been inserted.

The lower housing 16 is arranged on the floor side and connected to the upper housing 10. The lower housing 16 is detachable from the upper housing 10. For example, when irradiating the toenails located on the floor with ultraviolet rays, the lower housing 16 and the finger placement table 20 are removed, and only the upper housing 10 side is covered with the feet. (Not shown).

FIG. 2 shows a state in which the arrangement of the LED light source group 40 is looked up from the lower side. The LED light source group 40 includes a plurality of LEDs. The LED light source group 40 is fixed to the inner cover 30 disposed along the inner wall of the upper housing 10. Therefore, the inner cover 30 also includes a ceiling portion 30A, a side surface portion 30B, and a back portion 30C. The back portion 30C of the inner cover 30 is formed with a pair of inclined surfaces 32 so that the central depth is the deepest and the depths on both sides are shallow. The inner cover 30 is disposed so as to cover at least the nail side of the fingertips of the user's limbs, and corresponds to the nail side cover member of the present invention.

The inner wall of the inner cover 30 becomes a light absorbing surface that absorbs ultraviolet rays. This light absorption surface is realized by applying a black paint having ultraviolet absorption characteristics to the inner wall. Thereby, stable light irradiation is realized by irradiating the direct light from the LED light source group 40 mainly on the nail while preventing the irregular reflection of ultraviolet rays. In addition, ultraviolet rays are irregularly reflected in the inner cover 30 to prevent damage to skin other than the nails.

The LED light source group 40 includes a first LED 40A for irradiating the nail of the thumb with ultraviolet rays, a second LED 40B for irradiating the little fingernail with ultraviolet rays, a third LED 40C for irradiating the index finger or ring finger nail with ultraviolet rays, and a second LED 40C for irradiating the nail of the middle finger with ultraviolet rays. It has 4LED40D. One first LED 40A is arranged on the ceiling 30A above the thumb and two along the depth direction of the side surface 30B. Two second LEDs 40B are disposed on the ceiling portion 30A above the little finger along the longitudinal direction of the finger and one on the inclined surface 32 of the back portion 30C. Four third LEDs 40C are arranged along the longitudinal direction of the finger on the ceiling portion 10A above the index finger or ring finger, and one on the inclined surface 32 of the back portion 10C. Four fourth LEDs 40D are arranged on the ceiling portion 10A above the middle finger along the longitudinal direction of the finger, and one in the innermost portion of the back portion 10C. Except for the fourth LED 40D located at the center, the first to third LEDs 40A to 40C are arranged symmetrically with respect to the center line so as to correspond to the left and right hands and the left and right feet.

FIG. 3 shows the arrangement of the LED illumination group 40 and the positional relationship of the inserted hand. For example, the fourth LED 40D corresponding to the middle finger will be described in detail. These LED 40D _{1 to 4} are arranged opposite to the nail and irradiate light on the surface of the nail, and are arranged in the vicinity of the extension line of the finger. The fingertip side LED 40D ₅ for irradiating light from the axial direction of the finger is provided. By combining the two types of optical axes of the LED on the opposite side and the fingertip side, each nail is effectively irradiated with ultraviolet rays, and the nail resin is cured in a short time (for example, 10 seconds). The number of LEDs arranged for each nail is not particularly limited, but at least one (preferably a plurality) at a position facing the surface of the nail and at least 1 at other angles (side surface or tip side). It is preferable that the two types of optical axes intersect each other toward the nail.

Returning to FIG. 1B, the wiring board 42 for the LED light source group 40, the power supply device 50, and the control device 60 are accommodated in the gap between the inner cover 30 and the upper housing 10. The LED light source group 40 is fixed to the wiring board 42. The power supply device 50 converts electricity supplied via the power cable 70 into a predetermined DC voltage. The power supply device 50 has a built-in battery and can store a current supplied from the power cable 70. Therefore, even if the power cable 70 is removed, it can be used.

FIG. 4 shows a finger placement table 20. The palm of the user's hand abuts on the finger placement table 20. That is, the finger placement table 20 faces the belly of the fingertip and corresponds to the ventral cover member of the present invention. The finger placement table 20 is preferably arranged with at least four ventral sides of at least four fingers from the thumb to the little finger. In this embodiment, the five fingertips from the thumb to the little finger are placed together. The size is possible.

The finger placement table 20 is formed with a housing portion 22 that houses a seal end portion 112 (see FIG. 13) of an expansion seal (nail resin holding member) 110 provided on the fingertip. Specifically, the accommodating portion 22 includes a first opening 22A for the little finger or thumb, a second opening 22B for the index finger or ring finger, and a third opening 22C for the middle finger. A pair of first and

second openings

22A and 22B are arranged symmetrically with respect to the third opening 22C located in the center. As a result, the accommodating part 22 is formed with a total of five openings. Of course, in the present invention, the number of openings is not particularly limited. Preferably, it is formed in at least four places.

As shown in FIG. 5, the accommodating portion 22 includes a region that is narrower than the finger width of the fingertip, and has a generally thin slit shape in the present embodiment. Therefore, the finger placement table 20 can insert the seal end 112 into the accommodating portion 22 while supporting the belly side of the finger. As a result, even if the seal end 112 is not cut in advance, the interference between the seal end 112 and the finger placement table 20 is avoided.

Returning to FIG. 4, particularly in the present embodiment, the accommodating portion 22 includes a slit shape extending in the longitudinal direction of the finger, and the end portion of the accommodating portion 22 is the user side edge portion 20 </ b> A of the finger placement table 20. Has reached. Therefore, the user inserts the seal end portion 112 from the user side edge portion 20A of the housing portion 22 and slides the fingertip to the back side. A protrusion 24 that abuts against the abdomen of the fingertip (the tip side of the first joint) is formed around the housing portion 22. The user stops the finger slide at the time when the tip of the fingertip comes into contact with the protrusion 24. As described above, when the fingertips are stopped at the optimum positions using the protrusions 24 while the seal end 112 is guided by the accommodating portion 22, the LED light source group 40 is optimally arranged with respect to the nails of each fingertip. As a result, the nail gel can be efficiently cured.

In addition, although the case where the accommodating portion 22 that accommodates the seal end portion 112 includes a slit shape is illustrated here, the present invention is not limited to this. For example, like the finger placement table 20 shown in FIG. 6, the fingers themselves may be supported by a plurality of columns 26. As shown in FIG. 7, the height H <b> 1 of the column 26 is set to be larger than the protruding length H <b> 2 of the seal end portion 112. In this way, the entire area other than the support column 26 becomes the accommodating portion 22, so that the interference between the seal end portion 112 and the finger placement table 20 can be prevented.

Further, for example, like the finger placement table 20 shown in FIG. 8, it is also possible to provide a support base 28 that supports the proximal end side of the finger while at least opening the entire distal end side from the first joint of the finger. In this way, as shown in FIG. 9, the entire region behind the support base 28 becomes the accommodating portion 22, so that interference between the finger placement table 20 and the seal end portion 122 can be further suppressed. A protrusion 24 corresponding to each finger is formed on the support base 28, and the finger is positioned by contacting the protrusion 24 between the first and second joints of the finger. At this time, although not particularly illustrated, a slit for guiding the seal end portion 122 from the near side to the accommodating portion 22 may be provided in the support base 28.

Further, as is common to all the other finger placement tables 20 exemplified, it is preferable that the finger placement table 20 is slidably placed as shown in FIG. It is also possible to pull out the finger placement table 20 on the front side, place the hand, and then insert the hand into the casing together with the finger placement table 20.

FIG. 11 shows a circuit configuration of the LED light source group 40. In the present embodiment, the LEDs are connected in series so as to straddle the LEDs of the first LED 40A, the second LED 40B, the third LED 40C, and the fourth LED 40D. As a result, for example, since the LED elements belonging to the fourth LED 40D are connected in parallel, even if some trouble occurs in some of the wiring, a situation where all LEDs that irradiate the middle fingernail cannot be turned on is avoided. it can. That is, it is preferable to supply current separately to a plurality of LEDs on each claw via a plurality of wirings.

Next, the lighting control mode of the LED light source group 40 by the control device 60 will be described.

(1) Timer mode: After pressing the power button 12A, the hand is inserted, and the irradiation time is set by combining the 5-second setting button 12C, the 10-second setting button 12D, and the 20-second setting button 12E. The LED light source group 40 is turned on simultaneously with the setting. On the display screen 12F, the “number of remaining seconds” in the countdown format is displayed. When the set time elapses, the LED light source group 40 is automatically turned off.

(2) Auto mode (basic): Press the power button 12A and then press the auto setting button 12B. Thereafter, when the hand is inserted, the insertion of the hand is automatically detected by the distance sensor 11 in the housing, and the LED light source group 40 is automatically turned on. The “irradiation elapsed time” in the count-up format is displayed on the display screen 12F. When the desired time has elapsed, remove your hand from the housing. Hand extraction is automatically detected by the distance sensor 11 in the housing, and the LED light source group 40 is automatically turned off. When the hand is inserted again, the LED light source group 40 is automatically turned on, and the irradiation elapsed time is counted up again from zero seconds on the display screen 12F.

(3) Auto mode (with timer): Press the power button 12A, then press the auto setting button 12B, and further set the irradiation time with a combination of the 5 second setting button 12C, the 10 second setting button 12D, and the 20 second setting button 12E. . The LED light source group 40 is turned on only while the hand is detected by the distance sensor 11, and the “remaining number of seconds” in the countdown format is displayed on the display screen 12F from the set time. When the hand is pulled out halfway, the “number of remaining seconds” pauses, and when the hand is inserted again, the countdown of the number of remaining seconds resumes. When the remaining number of seconds becomes zero, the LED light source group 40 is automatically turned off. Even when the auto setting button 12B is pressed in the middle of the timer mode (1), the state transits to the auto mode (with timer) at the time set in (1).

As mentioned above, in the light irradiation apparatus 1 of this embodiment, the accommodating part 22 is formed at least near the fingertip in the finger placement table 20 that supports the belly side of the finger. As a result, since the seal end portion 112 of the expansion seal 110 can be accommodated, the finger can be inserted as it is without cutting the seal end portion 112 with scissors. As a result, in the light irradiation apparatus 1, the posture of the expansion seal 110 attached to the fingertip is stable, and the adhesion failure of the expansion seal 110 due to the cutting of the seal end 112 is suppressed, thereby forming a beautiful nail. be able to. Further, the finger placement table 20 can arrange at least four fingertips together, and the accommodating portion 22 can also accommodate at least four fingertip seal end portions 112, so that the nail gel can be efficiently applied. It can be cured.

Furthermore, the accommodating part 22 includes an area narrower than the finger width of the fingertip. In other words, the fingertip support function can be secured on both sides of the narrow region while the seal end 112 is inserted or passed through the narrow region of the accommodating portion 22. In particular, the slit shape as in this embodiment can support the belly of the fingertip while guiding the seal end 112. Furthermore, since the protrusion 24 which contacts the belly of the fingertip is formed around the housing portion 22, the user can grasp the stop position of the fingertip with a tactile sensation. As a result, it is possible to place the fingertip at an optimal location with respect to the LED light source group 40.

Further, the LED light source group 40 includes a facing side light source disposed facing the nail and a fingertip side light source disposed near the extension line of the finger. As a result, the optical axes from the LEDs cross in the vicinity of the nail, and the nail can be irradiated with ultraviolet rays from multiple directions in a concentrated and multifaceted manner. Moreover, since the light absorption surface by a light absorptive material is formed in the inner wall of the inner cover 30, it can prevent irregular reflection of an ultraviolet-ray and can suppress the damage | damage by the ultraviolet-ray to the skin of a hand or a leg.

In addition, in this embodiment, although the structure which irradiates an ultraviolet-ray collectively to five fingertips was illustrated, this invention is not limited to this. For example, like a light irradiation device 200 as shown in FIG. 12, it is possible to adopt a pen type that individually irradiates one fingertip with ultraviolet rays. The light irradiation device 200 includes a main body portion 201 in which a battery and a control device (not shown) are accommodated, and a cylindrical insertion portion 202 for inserting fingers one by one. One surface of the inner peripheral wall of the insertion portion 202 serves as a claw-side cover member 202A that covers the user's claw, and the other surface corresponds to a ventral-side cover member 202B that covers the belly of the finger. A slit (accommodating portion) 222 for inserting the seal end portion 112 is formed in the ventral cover member 202B. Since the seal end portion 112 protrudes from the slit 222, the position of the fingertip can be estimated from the position of the seal end portion 112. Further, as long as the seal end portion 112 is inserted into the housing portion 222, the claw faces the LED light source group 240. In this way, the fingertip positioning itself can be simplified.

If the LED light source group 240 is turned ON with the manual switch 230, the nail resin can be easily cured by irradiating the nail with ultraviolet rays from the LED light source group 240. Moreover, since the LED light source group 240 is covered with the insertion portion 202, it is possible to suppress leakage of ultraviolet rays.

In addition, the light irradiation apparatus of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.

The light irradiation device of the present invention can be applied to various scenes in which a nail using a photocurable resin is cured.
