  By the way, in the said conventional hair growth adjustment light irradiation apparatus, the part with high temperature and high voltage, such as the light-emitting body 11 and the reflector 12 is accommodated in the housing 2 so that it cannot touch directly from the outside. Safety is ensured. However, since the lens 13 that transmits light emitted from the light emitter 11 needs to pass through the light and irradiate the skin, it has been exposed.

  In such a case, since the lens 13 is always exposed to the outside, dirt such as dust, sweat, cosmetics and the like are likely to adhere to the lens 13, There exists a problem that the light quantity from the light-emitting body 11 will fall. Furthermore, excessive heat generation is generated by irradiation to make up for the insufficient light quantity, and the risk of burns increases. In this regard, it was considered that a disposable protective film was attached to protect the lens 13 from dirt, but hand oil adhered to the lens 13 during the replacement of the protective film, and the replacement itself was very troublesome. There was also a problem.

  The present invention has been made in view of the above-described conventional problems. The object of the present invention is to provide a hair growth having a shutter that protects the lens by opening the shutter only during irradiation and closing the shutter when not in use. The object is to provide an adjusting light irradiation device.

  In order to solve the above-mentioned problem, in the invention according to claim 1, the light emitting part 1 that emits light for adjusting the growth of body hair of the skin to be treated, and the housing 2 that houses the light emitting part 1 therein. In the hair growth-regulating light irradiating apparatus, the housing 2 has an opening 3 for irradiating light emitted from the light-emitting unit 1, and an opening when the opening 3 is pressed against the skin to be treated. And a shutter 4 that closes the opening 3 when the opening 3 is separated from the skin to be treated.

  With this configuration, the lens 13 can be protected at all times by closing the shutter 4 when not in use, so that adhesion of dirt can be avoided and a clean lens 13 can be used during use. A sufficient amount of light from the light emitter 11 can be secured. Furthermore, since the shutter 4 that is opened when irradiated and closed when not in use is adopted, the lens 13 can be easily protected, and the hand does not touch the lens 13 directly, and there is a concern that dirt such as oil from the hand may adhere. It will be lost.

  According to the present invention, since it is not necessary to irradiate extra high energy light, the amount of light can be saved and it is economical, and the risk of burns can be avoided.

  The present invention will be described below with reference to the accompanying drawings. For convenience of explanation, the light irradiation direction is assumed to be the vertical direction, and in particular, the opening 3 of the housing 2 is assumed to be upward.

  1 (a) and 1 (b), as an example of the hair growth regulating light irradiation device in the embodiment of the present invention, a photo epilation device comprising therein a light emitting unit 1 that emits light for suppressing hair growth. Is shown. In the optical hair removal apparatus, the light emitting unit 1 is housed in a box-shaped housing 2 that can be held with one hand, and an opening 3 is formed on one end face in the longitudinal direction of the housing 2. The light-emitting unit 1 includes a light-emitting body 11, a condensing reflector 12 and a lens 13 as a transmission window for irradiating light emitted from the light-emitting body 11 to the outside. It is arranged. The lens 13 may be a light guide plate or a filter, and is not particularly limited to this embodiment. Further, as the light emitting unit 1, a flashlight composed of a xenon lamp is housed in the reflector 12 as a light emitter 11 for hair suppression, and the open surface of the reflector 12 faces the lens 13 provided in the housing 2. In the housing 2.

  The opening 3 in the end surface of the housing 2 is provided with a light-shielding cylindrical portion 32 that surrounds the end surface over the entire circumference. The cylindrical portion 32 protrudes above the lens 13, and a ring-shaped distal end surface 31 is formed in the peripheral portion of the distal end opening of the cylindrical portion 32. In addition, a control circuit connected to the light emitter 11 is housed in the housing 2, and a high voltage obtained by boosting a voltage supplied from a power source by the control circuit is applied to the light emitter 11. 11 is made to emit light with high energy. An irradiation switch 6 for manually operating on / off for light irradiation is provided on the outer peripheral surface of the housing 2 so as to be connected to the control circuit. In the figure, wiring is omitted.

  In order to perform a hair removal process using the above-described optical hair removal apparatus, the user holds the distal end surface 31 in the shape of a ring in a plan view of the cylindrical body part 32 with respect to the skin to be processed while holding the housing 2 body with one hand. The skin is pressed and set so that the skin to be processed is located within the region surrounded by the distal end surface 31. If the irradiation switch 6 is operated in this state to turn on the light irradiation, light emitted in a pulse form from the light emitter 11 is irradiated to the skin to be processed through the lens 13 and is applied to the body hair of the skin. Has a hair-loss effect. At this time, leakage of the irradiated flash light to the outside is prevented by maintaining the state in which the distal end surface 31 of the cylindrical body portion 32 is pressed against the skin over the entire circumference.

  The basic configuration of the hair growth adjusting light irradiation device has been described above based on the photo epilation device of the illustrated example. In the following, the configuration unique to the present invention will be described in more detail.

  In the optical hair removal device of the illustrated example, the shutter 4 is provided so as to cover the lens 13 provided on the end surface in the longitudinal direction of the housing 2, and the skin contact disposed on the front end surface 31 of the cylindrical body portion 32. The shutter 4 is opened and closed by turning on and off the sensor 5. The shutter 4 is configured by attaching a plurality of blades 42 to a ring plate 41 attached on the surface provided with the lens 13. The skin contact sensor 5 is a sensor for detecting contact with the skin or the like, but the skin contact sensor 5 may be a contact type sensor and is not particularly limited. The skin contact sensor 5 is provided in the housing 2 and connected to a control circuit that performs sensor control. The control circuit is connected to a motor drive unit, and the shutter 4 is opened and closed by the motor drive unit. In this way, the opening and closing of the shutter 4 is controlled.

  That is, in the shutter 4, as shown in FIGS. 2 and 3, a plurality of blades 42 are attached to the ring plate 41 at regular intervals in the circumferential direction of the ring plate 41 so as to be rotatable around the shaft 43. is there. The plurality of blades 42 are formed by sequentially overlapping adjacent blades 42 in one direction, and the shutter 4 is formed by sequentially overlapping the plurality of blades 42 in one direction.

  In the present embodiment, a ring-shaped rotation plate 44 is rotatably overlapped on the ring plate 41, and a plurality of pins 45 protruding on the rotation plate 44 at regular intervals in the circumferential direction are provided on the ring plate 41. A long hole 47 that is slidably fitted into a plurality of arc-shaped long holes 46 provided at regular intervals in the circumferential direction, and that the tip portions of the plurality of pins 45 are elongated toward the shaft 43 provided on each blade. It is slidably fitted in.

  The ring plate 41 is mounted on the surface on which the lens 13 is provided, and the rotating plate 44 is rotated with respect to the ring plate 41 (clockwise in the illustrated example), so that each pin 45 extends along the arc-shaped elongated hole 46. As a result, each pin 45 moves while pushing the edge of the elongated hole 47 that is elongated toward the shaft 43, so that each blade 42 moves clockwise or counterclockwise around the shaft 43. The shutter 4 that closes the lens 13 is formed by rotating in the clockwise direction (counterclockwise in the illustrated example). Further, the shutter 4 can be opened by rotating the rotating plate 44 in a direction opposite to the direction in which the shutter 4 is closed (counterclockwise in the illustrated example).

  When the skin contact sensor 5 detects the skin and is turned on, the rotation plate 44 is set to rotate counterclockwise to open the shutter 4 and the skin contact sensor 5 It is configured to close the shutter 4 by setting the rotating plate 44 to rotate clockwise when it is in an off state away from the skin. The correspondence relationship between the rotation direction of the rotating plate 44 and the skin contact sensor 5 is not limited to this embodiment, and the shutter 4 is configured to be opened when the skin contact sensor 5 is turned on. If the shutter 4 is configured to be closed when the skin contact sensor 5 is turned off, the effect of the present invention can be obtained.

  According to such a configuration, the shutter 4 is opened only when the skin surface closes the opening 3, so that dirt such as dust can be prevented from adhering to the lens 13. Further, by setting the skin contact sensor 5 to operate only when the irradiation switch 6 is turned on, it is possible to avoid malfunctions during storage.

  Although the skin contact sensor 5 in this embodiment is arrange | positioned in two places, it is not specifically limited, One place or more may be sufficient. Further, the opening operation may be performed in a state where all the skin contact sensors 5 at a plurality of locations are turned on, and the opening operation is activated while only the skin contact sensor 5 at one location is turned on. It may be constituted so that it is not particularly limited.

  Further, the configuration of the shutter 4 is not limited to this embodiment, and other configurations may be used.
