  The present invention has been invented in view of the above-described conventional problems, and can confirm the irradiation region of light irradiated from the light irradiation port before and during treatment, and reliably irradiate light on a desired part of the skin. It is an object of the present invention to provide a hair-growth adjusting light irradiation device that can perform reliable treatment.

  In order to solve the above-mentioned problem, the hair growth adjusting light irradiation device according to the present invention is provided with a light irradiation port 3 for irradiating light for adjusting the growth of body hair on the outer surface of the apparatus body 1, and the periphery of the light irradiation port 3. A cylindrical body 4 projecting in parallel with the light projecting axis direction, and the projecting tip surface of the cylindrical body 4 serves as a skin contact surface 9 for contacting the skin 11 and is surrounded by the projecting tip portion of the cylindrical body 4 The cylindrical body 4 is used as an irradiation area confirmation cylinder for confirming the irradiation area of the light irradiated from the light irradiation section by matching the area and the irradiation area of the light irradiated from the light irradiation port 3. It is characterized by that.

  Thus, the light irradiated from the light irradiation port 3 before and during treatment is made by matching the region surrounded by the projecting tip of the cylindrical body 4 with the irradiation region of the light irradiated from the light irradiation port 3. The irradiation area can be confirmed.

  In the present invention, it is possible to confirm the irradiation region of light emitted from the light irradiation port before and during treatment, and reliably apply light to a desired site on the skin.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. In the following description, the irradiation direction of the light emitted from the light source unit 2 is described as upward, that is, the light projection axis direction of the light emitted from the light source unit 2 indicated by a in FIG.

  The hair growth regulating light irradiation device of one example of this embodiment shown in FIG. 1 is an optical hair removal device that emits light for performing hair removal while suppressing the growth of body hair, and has a vertical housing 1a that can be gripped with one hand. The main body is composed of the constructed device body 1. A light source unit 2 for irradiating light for hair removal treatment is built in the upper end of the device main body 1, and the light source unit 2 is composed of a horizontally long tubular xenon lamp (flash light). The light source unit 2 irradiates linear light having directivity with a substantially constant irradiation region in the light projecting axis direction, for example, by providing a reflector (not shown) around the irradiation direction. A light irradiation port 3 is formed in a portion facing the light source unit 2 in the upper end surface portion of the housing 1 a, and light emitted from the light source unit 2 is irradiated upward outside the device main body 1 through the light irradiation port 3. The light irradiation port 3 has a rectangular shape slightly larger than the light source unit 2 in plan view and long in the length direction of the light source unit 2, and the light source unit 2 is located inside the light irradiation port 3 in plan view.

  Further, the hair growth adjusting light irradiation device includes a cylindrical body 4 protruding upward from the periphery of the light irradiation port 3 in parallel with the light projecting axis direction of the light source unit 2. The cylindrical body 4 has a rectangular cylindrical shape that is long in the length direction of the straight tubular light source section 2, and is provided so as to be floatable with respect to the apparatus main body 1. Here, the floatable state means that the cylinder 4 can be moved in the light projecting axis direction within a certain range while urging the cylinder 4 in the axial direction (that is, the light projecting axis direction) away from the device main body 1. It is in the state.

  In the illustrated example, the cylindrical body 4 is inserted into the light irradiation port 3, and the outer peripheral surface of the cylindrical body 4 is slidable up and down along the inner peripheral surface of the light irradiation port 3. A projecting portion 5 that protrudes outward is provided at the lower end of the cylindrical body 4, and a receiving portion 6 is provided on the inner peripheral surface of the housing 1 a of the device body 1. A spring member 7 is interposed between the receiving portion 6 and the convex portion 5, and the cylindrical member 4 is biased upward by the spring member 7. The housing 1 a is provided with a contact portion 8 positioned above the convex portion 5, and the convex portion 5 is pressed against the lower surface of the contact portion 8 by the urging force of the spring member 7 to prevent the tubular body 4 from coming off.

  The tip portion of the cylindrical body 4 protrudes upward from the upper end of the device main body 1, and a portion of the horizontal protruding tip surface over the entire circumference forms a skin contact surface 9 that contacts the skin 11. The light emitted from the light source unit 2 through the light irradiation port 3 is set along the inner peripheral surface of the cylindrical body 4, and the protruding tip of the cylindrical body 4 of the light irradiated from the light irradiation port 3 is set. The boundary between the irradiation region and the non-irradiation region in the part overlaps with the tip of the cylindrical body 4 in plan view. That is, the region surrounded by the projecting tip of the cylindrical body 4 and the irradiation region of the light irradiated from the light irradiation port 3 are completely coincident, and the user irradiates the cylindrical body 4 from the light irradiation port 3. It is set as the cylinder for confirming the irradiation region of the light to be performed. Note that the region surrounded by the projecting tip of the cylinder 4 and the irradiation region of the light irradiated from the light irradiation port 3 do not have to be exactly the same. For example, the region is surrounded by the projecting tip of the tube 4. The region surrounded by the projecting tip of the cylindrical body 4 and the light irradiation region irradiated from the light irradiation port 3 are substantially the same, such as overlapping the irradiation region of the light irradiated from the light irradiation port 3 over most of the region. It may be a match.

  A control circuit 10 electrically connected to the light source unit 2 is built in the housing 1a of the device main body 1. The control circuit 10 applies a voltage supplied from a power source (not shown) as a high voltage to the light source unit 2 to appropriately control on / off of light emission of the light source unit 2. It can be switched by operating an operation switch (not shown) provided on the outer surface of 1.

  When using the above-described hair growth regulating light irradiation device, the device body 1 is grasped with one hand after confirming the irradiation region irradiated on the skin 11 from the light irradiation port 3 by looking at the protruding tip of the cylindrical body 4. As shown in FIG. 2, the skin contact surface 9 of the cylinder 4 is applied to the skin 11 of a human body such as an armpit, and the treatment target site of the skin 11 is positioned in the region surrounded by the skin contact surface 9. When the device body 1 is further pushed into the skin 11 in this state, the cylindrical body 4 sinks downward while increasing the upward biasing force, and the skin contact surface 9 is in close contact with the skin 11 over the entire circumference. To do. Here, even if the device main body 1 is moved somewhat, the cylinder 4 that is floatable follows and moves up and down and maintains the state where the skin contact surface 9 is in close contact with the skin 11.

  And light is irradiated to the skin 11 used as a process target site | part by emitting the intermittent pulse-like flash from the light source part 2 in the state which contact | adhered the skin contact surface 9 of the cylinder 4 to the skin 11 in this way. . Thereby, the light energy emitted from the light source unit 2 is transmitted to the hair and heated, so that it is difficult for the hair to reach the hair and the hair removal process is performed. At this time, the region surrounded by the projecting tip of the cylindrical body 4 in contact with the skin 11 coincides with the irradiation region of the light irradiated from the light irradiation port 3, so that the user can project the cylindrical body 4. It is possible to irradiate the skin 11 with the light from the light irradiation port 3 while confirming the irradiation region of the light irradiated on the skin 11 by looking at the tip.

  As described above, the hair-growth adjusting light irradiation device of the present invention includes the region surrounded by the protruding tip portion of the cylindrical body 4 and the light irradiation port 3 as the skin contact surface 9 that makes the protruding tip surface contact the skin 11. By matching the irradiation area of the irradiated light, the irradiation area of the light irradiated from the light irradiation port 3 can be confirmed before and during treatment, and light can be reliably applied to a desired part of the skin 11. it can.

  In addition, the cylinder 4 may be formed of any member that is transparent, translucent, or opaque. In the case of being transparent or translucent, the light irradiated to the skin 11 surrounded by the skin contact surface from the light irradiation port 3 Can be confirmed, and it can be confirmed that the light is applied to the skin 11, and when it is opaque, the cylindrical body 4 can prevent the reflected light and the like from leaking outside. Moreover, although the said cylinder 4 was provided movably with respect to the apparatus main body 1, the cylinder 4 may protrude integrally from the peripheral part of the light irradiation port 3 of the apparatus main body 1. FIG. In addition, a transparent lamp cover 12 that closes the light irradiation port 3 may be disposed at the light irradiation port 3 as shown in FIG. 3, and in this case, light from the light source unit 2 enters the light irradiation port 3. The light is emitted toward the outside of the device main body 1 through the provided lamp cover 12. Further, the light source unit 2 is not limited to a flashlight made of xenon light, but may be another flashlight, or may be a laser diode or the like that emits laser light. The hair growth adjusting light irradiation device may be an optical hair growth device that emits light for promoting the growth of body hair from the light source unit 2 and irradiates the skin 11 with this light to grow hair, that is, the light source unit. 2 may emit light for controlling the growth of body hair.
