Description

The present disclosure relates to an ultraviolet irradiator that irradiates eyewear with ultraviolet rays.

Examples of the ultraviolet irradiator that irradiates the eyewear with ultraviolet rays include a spectacle case described in Japanese Patent Application Laid-Open No. 10-85022. The spectacle case includes an upper case, a lower case rotatably connected to the upper case via a hinge, and a pair of lamps provided on the inner surface of the upper case. The pair of lamps are fixed to the recessed portion inside the upper case so as to face each of the lenses of the spectacles, and irradiate each of the pair of lenses with ultraviolet rays.

A charger is fixed to the inner surface of the upper case, and a lead wire with a plug attached to the tip extends from the charger. A protrusion that projects inward is formed in the center of the inside of the front edge of the upper case, and the protrusion is provided with a hook that engages with the lower case. A protrusion protruding inward is formed in the center of the inside of the front edge portion of the lower case, and a hook hole with which the hook of the upper case is engaged is formed in the protrusion.

By engaging the hook of the upper case with the hook hole of the lower case, the upper case is kept closed in the lower case. Further, a case switch is provided so as to project upward on the back side of the hook hole in the protruding portion of the lower case. The case switch is a push button type switch, and when the upper case is closed, the protruding portion of the upper case abuts and is pushed in.

A manual switch is located in the left corner of the front of the lower case. The manual switch is a switch for manually operating the ON / OFF of the pair of lamps described above. When the glasses are not put in the case, or when the anti-fog property of the glasses is sufficient, the manual switch is turned off.

The spectacle case includes an electric circuit for supplying power to the pair of lamps described above. In this electric circuit, the case switch and the manual switch described above are arranged in series. Therefore, when the upper case is closed in the lower case, the case switch is turned on, and the manual switch is turned on, the pair of lamps are turned on and each of the pair of lenses of the spectacles is irradiated with ultraviolet rays.

Japanese Unexamined Patent Publication No. 10-85022

In the above-mentioned spectacle case, a pair of lamps are fixed to the upper case, and an electric circuit for lighting the pair of lamps is built in the spectacle case. The above-mentioned spectacle case is a special spectacle case in which a pair of lamps are fixed and an electric circuit is built in, and an eyewear case for accommodating the spectacles and an ultraviolet irradiation means are integrated. Therefore, in the above-mentioned eyeglass case, even if you have a ready-made eyewear case, you have to purchase the whole eyeglass case if you want to use the ultraviolet irradiation function, and the ready-made eyewear case is unnecessary. It is not economical because it becomes. That is, the current situation is that the irradiation function cannot be diverted to a ready-made eyewear case.

Further, in the above-mentioned eyeglass case, a lamp is provided in the upper case, a case switch is provided in the central protruding portion inside the front edge portion of the lower case, and a manual switch is provided in the front surface of the lower case. Further, an electric circuit for turning these switches on and off is built-in. Therefore, since the electric wiring must be laid in a limited area of the upper case and the lower case, a problem that the configuration is complicated may occur.

It is an object of the present disclosure to provide an ultraviolet irradiator capable of diverting the irradiation function to a ready-made eyewear case and simplifying the configuration of the apparatus.

The ultraviolet irradiator according to the present disclosure is an ultraviolet irradiator that irradiates eyewear with ultraviolet rays, and is a base housed in an eyewear case for accommodating eyewear and a base fixed to the base and housed in the eyewear case. It is provided with an irradiation element that irradiates the worn eyewear with ultraviolet rays and a lighting means for lighting the irradiation element, and the base is removable from the eyewear case.

According to the present disclosure, the irradiation function can be diverted to a ready-made eyewear case, and the configuration of the device can be simplified.

FIG. 3 is a perspective view showing the ultraviolet irradiator of FIG. 2 and the eyewear case in an open state. It is a perspective view which shows the ultraviolet irradiation device of FIG. FIG. 5 is a perspective view of the ultraviolet irradiator of FIG. 5 as viewed from a direction different from that of FIG. FIG. 3 is a block diagram showing a sensor, a control unit, an irradiation element, and a notification means of the ultraviolet irradiator of FIG. 2. It is a perspective view which shows the ultraviolet irradiation device which concerns on a modification.

Hereinafter, embodiments of the ultraviolet irradiator according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are designated by the same reference numerals, and duplicate description will be omitted as appropriate. In addition, the drawings are partially simplified or exaggerated for the sake of easy understanding, and the dimensional ratios and the like are not limited to those described in the drawings.

In the present disclosure, "eyewear" refers to an instrument worn to cover the wearer's eyes. "Eyewear" includes eyeglasses for correcting refractive errors of the eye such as myopia, hyperopia or astigmatism, sunglasses for decorating the periphery of the eye, and goggles for protecting the eye. In this embodiment, the eyewear is irradiated with ultraviolet rays. "Ultraviolet rays" indicate light having a wavelength of 10 nm or more and 420 nm or less. The lower limit of the wavelength band of "ultraviolet rays" may be 100 nm, 150 nm, 200 nm, 250 nm or 300 nm. Further, the upper limit of the wavelength band of "ultraviolet rays" may be 400 nm, 380 nm or 350 nm. The wavelength band of "ultraviolet rays" may include a part of the wavelength band of visible light. The purpose of irradiating the eyewear with ultraviolet rays includes various purposes. The purpose of irradiating the eyewear with ultraviolet rays is, for example, sterilization, but it may be anti-fog, for example, and is not particularly limited.

The eyewear is housed in an eyewear case. In the present disclosure, the "eyewear case" is a container in which eyewear can be placed. For example, the "eyewear case" may be a box-shaped container or a bag-shaped container. As described above, the ultraviolet irradiator according to the present embodiment can be applied to various eyewear cases.

FIG. 1 is a perspective view showing the appearance of an exemplary eyewear case C to which the ultraviolet irradiator 1 according to the present embodiment is applied. FIG. 2 is a perspective view showing the eyewear case C, the ultraviolet irradiator 1, and the eyewear E in an open state. As shown in FIGS. 1 and 2, the eyewear E is housed inside the eyewear case C together with the ultraviolet irradiator 1. The exemplary eyewear case C exhibits a rectangular parallelepiped shape with rounded corners.

The eyewear case C has a plurality of long sides C11 extending in the first direction D1 and a plurality of short sides C12 extending in the second direction D2 intersecting the first direction D1. It has a thickness in the third direction D3 that intersects both sides. The eyewear case C includes a mounting portion C1 on which the ultraviolet irradiator 1 and the eyewear E are mounted, and a lid portion C2 that covers the ultraviolet irradiator 1 and the eyewear E mounted on the mounting portion C1.

The mounting portion C1 has an opening C4 that is directed upward. As an example, the opening C4 has a rectangular shape with rounded corners. The lid portion C2 is a portion that functions as a lid that opens and closes the opening C4 of the mounting portion C1. The lid portion C2 is openable and closable with respect to the mounting portion C1 via the hinge portion C3 extending in the first direction D1 on one side (back side) of the second direction D2. That is, the lid portion C2 opens and closes the opening C4 of the mounting portion C1 on which the ultraviolet irradiator 1 and the eyewear E are mounted via the hinge portion C3.

The mounting portion C1 has, for example, a box shape having an opening C4, an inner side surface C5 extending downward from the opening C4, and a bottom surface on which the ultraviolet irradiator 1 is placed. For example, the lid portion C2 has a box shape similar to that of the mounting portion C1, and has an opening C6, an inner side surface C7, and a bottom surface C8. A hinge portion C3 is provided between the end portion of the second direction D2 in the opening C4 of the mounting portion C1 and the end portion of the second direction D2 in the opening C6 of the lid portion C2.

The configuration of the exemplary eyewear case C has been described above. However, the configuration of the eyewear case is not limited to the configuration of the eyewear case C described above. Further, the ultraviolet irradiator 1 and the eyewear E according to the present embodiment can be housed in various eyewear cases other than the eyewear case C.

An exemplary eyewear E comprises a frame E1 and a pair of lenses E2 fixed to the frame E1. The frame E1 includes a front E3, a pair of hinges E4 provided on both ends of the front E3, and a pair of temples E6 extending from each hinge E4 in a direction intersecting the front E3. The front E3 has a pair of rims E7 surrounding the lens E2, a bridge E8 connecting the pair of rims E7 to each other, and a pair of pads E9 located below the bridge E8. As with the eyewear case, the eyewear is not limited to the above-mentioned eyewear E configuration. In this embodiment, as an example, an example in which the eyewear E is housed in the eyewear case C will be described.

As shown in FIGS. 2 and 3, the ultraviolet irradiator 1 according to the present embodiment irradiates the eyewear E housed in the eyewear case C with ultraviolet L. The ultraviolet irradiator 1 is removable from the eyewear case C. "Detachable" indicates a state in which it can be attached and detached. "Removable" includes, for example, a state in which it can be attached and detached, and indicates a state in which it can be put in and taken out of the eyewear case. In the present embodiment, the ultraviolet irradiator 1 is an irradiation kit that can be freely taken in and out of the eyewear case C.

For example, the ultraviolet irradiator 1 is housed in the eyewear case C, and the housed ultraviolet irradiator 1 is arranged so as to face the bottom surface of the eyewear case C (mounting portion C1). For example, the ultraviolet irradiator 1 does not have a joint with the eyewear case C. This makes it possible to more easily attach / detach the ultraviolet irradiator 1 to / from the eyewear case C. However, the ultraviolet irradiator 1 may have a joint portion with respect to the eyewear case C, and in this case, the ultraviolet irradiator 1 housed in the eyewear case C can be made more stable.

The ultraviolet irradiator 1 includes, for example, a base 2 that is freely put in and taken out of the eyewear case C, an irradiation element 3 that irradiates the eyewear E housed in the eyewear case C with ultraviolet L, and one of the eyewear E. A cushion portion 4 on which the portion is placed and a positioning portion 5 for determining the position of the eyewear E are provided. The base 2 has, for example, a main surface 2b that is directed upward, and an irradiation element 3 is fixed to the main surface 2b. The irradiation element 3 is, for example, an ultraviolet LED (Light Emitting Diode). The irradiation element 3 may protrude from the main surface 2b or may be embedded in the base 2. When the irradiation element 3 is embedded in the base 2, the irradiation element 3 may be embedded in the base 2 so that the height of the irradiation element 3 with respect to the base 2 is flush with the main surface 2b.

For example, the irradiation element 3 irradiates the front surface E21 of the lens E2 of the eyewear E with ultraviolet rays L. The irradiation element 3 has a rectangular plate shape as an example. For example, the ultraviolet irradiator 1 includes a positioning unit 5 located in the center of the first direction D1, a pair of irradiation elements 3 arranged on one side and the other side of the first direction D1 of the positioning unit 5, and a pair. The cushion portion 4 of the above is provided. For example, the central portion of the first direction D1 including the bridge E8 of the eyewear E is mounted on the positioning portion 5, and the rim E7 and the lens E2 are placed on one side and the other side of the first direction D1 when viewed from the positioning portion 5. Is located.

The front surface E21 of the lens E2 is curved in a convex shape, for example. Further, since the front surface E21 of the lens E2 is a portion of the eyewear E that is easily exposed to the outside air, it is possible to efficiently sterilize the eyewear E by irradiating the front surface E21 with ultraviolet rays L. .. The ultraviolet L is, for example, near-ultraviolet. In this case, as described above, the wavelength of the ultraviolet L is 200 nm or more and 380 nm or less.

As an example, the ultraviolet L is an ultraviolet C wave (hereinafter, may be referred to as UV-C). UV-C is an ultraviolet ray having a wavelength of 100 nm or more (or 200 nm or more) and 280 nm or less, and exerts a strong bactericidal action on the eyewear E by being irradiated to the eyewear E. Further, the irradiation of the ultraviolet L by the irradiation element 3 is performed only in the state where the eyewear case C is closed. As a result, it is possible to prevent the ultraviolet L from leaking to the outside of the eyewear case C, and safety is ensured.

For example, the eyewear E is placed on the base 2 with a part of the rim E7 (for example, the lower part) mounted on the cushion portion 4. As a specific example, the lens E2 extends diagonally upward from a part of the rim E7 mounted on the cushion portion 4, and the lens E2 extending diagonally upward is irradiated with ultraviolet rays L. As an example, the irradiation element 3 is arranged in a region including the center of the second direction D2 of the base 2, and the cushion portion 4 is arranged on one end side (front side) of the second direction D2 of the base 2.

The cushion portion 4 is formed, for example, in a horizontally long oval shape extending in the first direction D1 and having a pair of long sides arranged in the second direction D2. This makes it possible to face the cushion portion 4 to a wide area of the rim E7. The cushion portion 4 is made of rubber, for example, and is made of silicone rubber as an example. The material of the cushion portion 4 is not limited to rubber, and may be an elastic material or a flexible material different from rubber. Further, the cushion portion 4 may be omitted, and instead of the cushion portion 4, for example, the base 2 may be made of rubber, or at least a part of the positioning portion 5 may be made of rubber.

FIG. 4 is a perspective view showing the eyewear case C and the ultraviolet irradiator 1 in a state where the eyewear E is taken out from FIG. As shown in FIGS. 2 and 4, the base 2 has, for example, a long side 2c extending in the first direction D1 and a short side 2d extending in the second direction D2, and a plate having a thickness in the third direction D3. It is said to be in the shape. As an example, the shape of the base 2 in a plan view is a rectangular shape with rounded corners. However, the shape of the base 2 is not particularly limited.

The material of the base 2 is, for example, a resin. However, the material of the base 2 is not limited to the resin material and can be appropriately changed. For example, in a state where the base 2 is housed in the eyewear case C, a gap S may be formed between the outer surface 2f of the base 2 and the inner surface C5 of the eyewear case C. The gap S may be large enough to accommodate a finger, for example. In this case, it is possible to easily take out the base 2 from the eyewear case C. Further, a recess for finger hook may be formed from a part of the outer surface 2f of the base 2 to the inside of the base 2. In this case, the finger is hooked on the recess and the base 2 is taken out from the eyewear case C. Therefore, it becomes possible to take out the base 2 more easily.

FIG. 5 is a perspective view showing the ultraviolet irradiator 1 taken out from the eyewear case C. As shown in FIGS. 2, 4 and 5, the positioning portion 5 has a convex shape protruding from the main surface 2b of the base 2. The positioning portion 5 is, for example, a first convex portion 5b protruding on one side of the second direction D2, a second convex portion 5c protruding on the other side of the second direction D2, a first convex portion 5b, and a second convex portion. It has a recess 5d that is recessed between the portions 5c. For example, the height of the recess 5d is higher than the height of the main surface 2b of the base 2.

For example, the height of the first convex portion 5b with respect to the main surface 2b is higher than the height of the second convex portion 5c with respect to the main surface 2b. As an example, the base 2 is arranged in the eyewear case C so that the second convex portion 5c is located on the hinge portion C3 side. For example, the first convex portion 5b has a pair of inclined portions 5f that incline so that the width of the first convex portion 5b becomes narrower toward the center side of the second direction D2, and a second direction D2 in the pair of inclined portions 5f. It has a curved portion 5g that connects the ends on the center side of the above and projects in the second direction D2. As described above, since the width of the first convex portion 5b becomes narrower toward the center of the second direction D2, it is easy to arrange the eyewear E (for example, the pad E9).

The second convex portion 5c is provided on the opposite side of the first convex portion 5b with the concave portion 5d interposed therebetween, and has a rectangular parallelepiped shape, for example. The second convex portion 5c is a portion where the bridge E8 of the eyewear E faces. The recess 5d may be, for example, a portion where a part of the rim E7 and a part of the pad E9 enter. As a specific example, a part of each rim E7 on the center side of the first direction D1 and a part of each pad E9 enter the recess 5d. When the bridge E8 is placed on the second convex portion 5c and a part of the rim E7 and the pad E9 enters the concave portion 5d, the position of the eyewear E with respect to the positioning portion 5 is determined, and the lens E2 with respect to the irradiation element 3 is determined. Is maintained in a floating state. Therefore, it is possible to suppress the contact of the eyewear E with the irradiation element 3.

As described above, the irradiation element 3 and the cushion portion 4 are arranged on one side and the other side of the first direction D1 when viewed from the positioning portion 5. Each cushion portion 4 extends linearly from the positioning portion 5 toward the end portion side in the first direction D1. Each of the pair of irradiation elements 3 is provided, for example, at a position closer to the positioning portion 5 than the center of each cushion portion 4 extending in the first direction D1. That is, each irradiation element 3 is provided on the side of the positioning portion 5 in the center of each cushion portion 4.

The ultraviolet irradiator 1 further includes, for example, a sensor 6 that detects the open / closed state of the eyewear case C that houses the ultraviolet irradiator 1. As an example, the sensor 6 is a photoelectric sensor. In this case, the sensor 6 includes an emitting unit that emits light and a light receiving unit that receives light reflected by the emission of light from the emitting unit. The sensor 6 as a photoelectric sensor detects whether or not an object exists around the sensor 6 from the amount of light received by the light receiving unit.

The sensor 6 detects whether or not the ultraviolet irradiator 1 is housed in the eyewear case C and the eyewear case C is blocked. The sensor 6 as a photoelectric sensor emits light from, for example, an emitting portion, and detects whether or not an inner surface (for example, an inner side surface C5 or a bottom surface C8) of the eyewear case C exists around the sensor 6. Then, when the sensor 6 detects that the inner surface of the eyewear case C exists in the periphery, the sensor 6 detects that the eyewear case C accommodating the ultraviolet irradiator 1 is blocked.

FIG. 6 is a perspective view of the ultraviolet irradiator 1 as viewed from a direction different from that of FIG. As shown in FIGS. 5 and 6, the sensor 6 has three locations: a main surface 2b of the base 2, an end surface 2g of the base 2 facing the first direction D1, and a side surface 2h of the base 2 facing the second direction D2. It is fixed to each of. By detecting the open / closed state of the eyewear case C by each of the sensors 6 arranged at each of the three locations, it is possible to determine the open / closed state with higher accuracy.

In the above, an example in which the sensor 6 is a photoelectric sensor and the sensor 6 is arranged on each of the main surface 2b, the end surface 2g, and the side surface 2h has been described. However, the type, number, and arrangement location of the sensor 6 are not limited to the above example and can be appropriately changed. The sensor 6 may be, for example, a brightness sensor that detects the brightness (amount of light) of the surroundings, or a piezoelectric sensor that detects the blockage of the eyewear case C.

Further, the number of sensors 6 may be 2 or less or 4 or more. For example, the sensor 6 may be arranged on only one of the six faces of the base 2, or two faces, four or more faces, or all faces of the six faces of the base 2. Sensors 6 may be arranged in each. As the location of the sensors 6 and the number of the sensors 6 increase, the open / closed state of the eyewear case C accommodating the ultraviolet irradiator 1 can be detected with higher accuracy.

As an example, the base 2 includes a dry battery accommodating portion 2j in which a dry cell is accommodating. The dry battery accommodating portion 2j accommodates a dry cell that supplies electric power to the irradiation element 3 described above. In this way, in the ultraviolet irradiator 1, electric power is supplied by a dry battery. Therefore, the wiring extending from the base 2 can be eliminated, and the configuration of the ultraviolet irradiator 1 can be simplified. As an example, the dry battery accommodating portion 2j is provided on the surface opposite to the main surface 2b. The power supply means in the ultraviolet irradiator 1 is not limited to the dry battery described above, and may be, for example, a rechargeable battery.

The ultraviolet irradiator 1 includes a lighting means 7 for lighting the irradiation element 3 described above, and a notification means 10 for notifying that the lighting means 7 is lighting the irradiation element 3. FIG. 7 is a block diagram showing the configurations of the irradiation element 3, the lighting means 7, and the notification means 10. As shown in FIGS. 6 and 7, for example, a circuit board 8 is provided inside the base 2.

Each of the irradiation element 3 and the sensor 6 is electrically connected to each other via the circuit board 8. The lighting means 7 includes a sensor 6 and a control unit 9, and the control unit 9 controls irradiation of ultraviolet rays L from each irradiation element 3. The intensity of the ultraviolet L emitted from the eyewear E by the irradiation element 3 is, for example, constant, and may be predetermined by an experiment, a simulation, or the like. Further, the intensity of the ultraviolet L may be variable, an adjusting means capable of adjusting the intensity of the ultraviolet L may be provided, or the control unit 9 may automatically control the intensity of the ultraviolet L. ..

The notifying means 10 is connected to, for example, the control unit 9, and is controlled by the control unit 9 to notify the user of the ultraviolet irradiator 1 whether or not the irradiation element 3 is lit. The notification means 10 may be, for example, a voice output unit that outputs voice when the control unit 9 lights the irradiation element 3, or vibrates when the control unit 9 lights the irradiation element 3. It may be a vibrator. Further, when the control unit 9 turns on the irradiation element 3, the notification means 10 turns on the irradiation element 3 on the information terminal (for example, a mobile terminal such as a smartphone or a tablet) of the user of the ultraviolet irradiator 1. It may be a communication means for notifying.

In this case, for example, the notification means 10 notifies the user's mobile terminal that the irradiation element 3 is lit via e-mail or an application. In this way, the notification means 10 notifies that the irradiation element 3 is lit, so that the user of the ultraviolet irradiator 1 can grasp that the irradiation element 3 is lit inside the eyewear case C. .. Then, the notification means 10 can prevent the user from accidentally opening the eyewear case C while irradiating the ultraviolet L. Further, by the notification means 10, the user cannot directly grasp the lighting state (whether or not it is lit) of the irradiation element 3 when the eyewear case C is closed, whether the battery has run out, and the irradiation element 3 It is possible to grasp whether there is a problem that does not light up. Further, the ultraviolet irradiator 1 may be provided with the above-mentioned dry battery or the remaining amount notifying means for notifying the remaining amount of the battery, similarly to the notifying means 10.

Each of the plurality of sensors 6 detects whether the ultraviolet irradiator 1 is housed in the eyewear case C and whether the eyewear case C is blocked. The control unit 9 turns on the irradiation element 3 when, for example, all the sensors 6 detect the blockage of the eyewear case C. For example, the control unit 9 may turn on the irradiation element 3 for a certain period of time (for example, 10 seconds or more and 10 minutes or less) and turn off each irradiation element 3 after the fixed time has elapsed. In this case, the eyewear E can be automatically irradiated with the ultraviolet L for a certain period of time, so that the manual switch can be eliminated.

The time for the irradiation element 3 to irradiate the ultraviolet L may be constant as described above, or may be predetermined by an experiment, a simulation, or the like, like the intensity of the ultraviolet L. Further, the time for irradiating the ultraviolet L may be variable, an adjusting means capable of adjusting the irradiation time (lighting time) of the ultraviolet L may be provided, or the control unit 9 automatically determines the ultraviolet L. The irradiation time may be controlled.

Next, the action and effect obtained from the ultraviolet irradiator 1 according to the present embodiment will be described in detail. As illustrated in FIGS. 2 and 3, in the ultraviolet irradiator 1, the base 2 is housed in the eyewear case C, and the irradiation element 3 for irradiating the eyewear E with the ultraviolet L is fixed to the base 2. The irradiation element 3 is lit by the lighting means 7. The base 2 to which the irradiation element 3 that irradiates the eyewear E with the ultraviolet L is fixed is detachable with respect to the eyewear case C.

Therefore, it is possible to take out the base 2 and the irradiation element 3 from the eyewear case C and store the taken out base 2 and the irradiation element 3 in another eyewear case. Therefore, since the base 2 with the irradiation element 3 can be stored in the ready-made eyewear case, the irradiation function can be diverted to the ready-made eyewear case. Since the irradiation function can be diverted to a ready-made eyewear case, there is no need to purchase a new eyewear case when the irradiation function of ultraviolet L is desired to be used.

Therefore, it is economical because the ready-made eyewear case can be continued to be used. Further, the irradiation element 3 and the base 2 are provided separately from the eyewear case C. Therefore, the electric wiring or the electric circuit is not incorporated in the eyewear case C, and the circuit board 8 and the like can be integrated in the base 2. As a result, the configurations of the ultraviolet irradiator 1 and the eyewear case C can be simplified.

The base 2 may include a positioning unit 5 that determines the position of the eyewear E with respect to the base 2. In this case, since the position of the eyewear E housed in the eyewear case C is determined by the positioning unit 5, the eyewear E can be stably arranged inside the eyewear case C. Therefore, since the ultraviolet L can be irradiated from the irradiation element 3 to the stably arranged eyewear E, it is possible to more efficiently irradiate the eyewear E with the ultraviolet L.

The base 2 may have a main surface 2b to which the irradiation element 3 is fixed, and the positioning portion 5 may have a convex shape protruding from the main surface 2b. In this case, the positioning portion 5 is convex with respect to the main surface 2b of the base 2 to which the irradiation element 3 is fixed. Therefore, when the position of the eyewear E is determined by the convex positioning portion 5, the eyewear E can be made difficult to come into contact with the irradiation element 3.

The irradiation element 3 may irradiate the eyewear E with UV-C as ultraviolet L. In this case, since UV-C, which is particularly effective in sterilization, can be irradiated to the eyewear E, the eyewear E can be sterilized more efficiently by irradiating the eyewear E.

As illustrated in FIGS. 6 and 7, the lighting means 7 is detected by the sensor 6 that detects the open / closed state of the eyewear case C with the base 2 housed in the eyewear case C, and the sensor 6. It may have a control unit 9 that controls the irradiation of the irradiation element 3 according to the open / closed state, and the control unit 9 turns on the irradiation element 3 when the blocked state of the eyewear case C is detected. May be good. In this case, the sensor 6 detects the open / closed state of the eyewear case C accommodating the base 2, and the control unit 9 turns on the irradiation element 3 when the blocked state of the eyewear case C is detected. Therefore, it is possible to prevent the irradiation element 3 from lighting when the eyewear case C accommodating the base 2 is not closed, so that unnecessary irradiation of the irradiation element 3 is suppressed to improve safety. Can be enhanced.

The sensor 6 may be a photoelectric sensor that converts light into an electric signal. In this case, unlike a push button or the like, no external force is required, so that the configuration of the sensor 6 itself can be simplified. Further, by using the photoelectric sensor, the irradiation element 3 is not turned on when the base 2 is not housed in the eyewear case C or the eyewear case C is open and there is no object around the base 2. Can be.

The base 2 has a plate shape, the lighting means 7 has a plurality of sensors 6, and the plurality of sensors 6 may be attached to each of the plurality of surfaces of the base 2. In this case, each of the plurality of sensors 6 is attached to each of the plurality of surfaces of the base 2, and even if one sensor 6 erroneously detects the sensor 6, the other sensor 6 appropriately detects the sensor 6. The malfunction of the lighting means 7 can be suppressed more reliably. Therefore, it is possible to control the lighting of the irradiation element 3 with higher accuracy.

As illustrated in FIG. 3, the ultraviolet irradiator 1 may include a plurality of irradiation elements 3, and the plurality of irradiation elements 3 are mounted on a surface (for example, the front surface E21) facing the front of the lens E2 of the eyewear E. It may be arranged at opposite positions. The front-facing surface of the lens E2 of the eyewear E is a portion that is exposed to the front when viewed from the wearer wearing the eyewear E, and is a portion of each part of the eyewear E that is easily exposed to the outside. Therefore, since a plurality of irradiation elements 3 face each other on the front-facing surface of the eyewear E to which bacteria and the like are likely to adhere, sterilizing the bacteria and the like is more effective by irradiating the surface with ultraviolet rays L from each irradiation element 3. Can be done.

As illustrated in FIG. 7, the ultraviolet irradiator 1 may include a notification means 10 for notifying that the lighting means 7 is lighting the irradiation element 3. In this case, since the notification means 10 notifies whether or not the eyewear E is irradiated with the ultraviolet L, it is possible to easily grasp whether or not the eyewear E is irradiated with the ultraviolet L.

As illustrated in FIG. 2, the base 2 may include a cushion portion 4 with which a part of the eyewear E comes into contact. In this case, the eyewear E is housed in the eyewear case C with a part of the eyewear E in contact with the cushion portion 4.

The embodiment of the ultraviolet irradiator according to the present disclosure has been described above. However, the present disclosure is not limited to the above-described embodiment, and may be modified or applied to other things without changing the gist described in each claim. That is, the configuration, function, shape, size, number, material, and arrangement mode of each part of the ultraviolet irradiator can be appropriately changed as long as the above gist is not deviated.

For example, in the above-described embodiment, the ultraviolet irradiator 1 provided with the plate-shaped base 2 has been described. However, the shape of the base is not limited to the plate shape. As shown in FIG. 8, the ultraviolet irradiator 21 may have a variable size. The ultraviolet irradiator 21 according to the modified example includes a base 22 and a slide portion 25 nested with respect to the base 22, and the slide portion 25 can be freely taken in and out of the base 22. The slide portion 25 is freely accessible to and from the base 22 at the end of the first direction D1 of the base 22, and the first ultraviolet irradiator 21 is provided by adjusting the amount of protrusion of the slide portion 25 from the base 22. The length of the direction D1 can be adjusted.

FIG. 8 shows an example in which the ultraviolet irradiator 21 includes a pair of slide portions 25 arranged along the first direction D1. In the case of the ultraviolet irradiator 21, the amount of protrusion of the slide portion 25 with respect to the base 22 can be adjusted on both sides of the first direction D1. However, the ultraviolet irradiator 21 is provided with a slide portion 25 at one end of the first direction D1, and the amount of protrusion of the slide portion 25 with respect to the base 22 can be adjusted only on one side of the first direction D1 (one of the right side and the left side). It may have been done. As described above, in the ultraviolet irradiator 21, the length of the first direction D1 can be adjusted, so that the eyewear cases having different lengths of the first direction D1 can be stored exactly. .. That is, the length of the first direction D1 of the ultraviolet irradiator 21 can be made variable according to the size of the eyewear case.

In the above example, the ultraviolet irradiator 21 including the slide portion 25 which is freely accessible to and from the base 22 at the end of the first direction D1 of the base 22 has been described. However, for example, instead of the slide portion 25, a slide portion that is freely put in and taken out of the base 22 in the second direction D2, or a slide portion that is freely put in and taken out of the base 22 in the third direction D3. May be provided. In this case, the ultraviolet irradiator can be stored exactly in the eyewear case having a different length in the second direction D2 or the eyewear case having a different length in the third direction D3.

In the above-described embodiment, an example in which the sensor 6 which is a photoelectric sensor detects the blocked state of the eyewear case C and the irradiation element 3 is automatically turned on has been described. As described above, the type of sensor that detects the blocked state of the eyewear case C may be other than the photoelectric sensor, or may be a combination of the photoelectric sensor and another sensor. As an example, a photoelectric sensor and a piezoelectric sensor may be provided as sensors. Further, the lighting means for lighting the irradiation element 3 may be something other than a sensor, and may be, for example, a manual operation switch.

In the above-described embodiment, the ultraviolet irradiator 1 having a plate-like shape and a resin base 2 has been described. However, the material of the base 2 is not particularly limited, and may include, for example, a surface in which at least a part of the main surface 2b of the base 2 is mirror-finished. In this case, since the ultraviolet L emitted from the irradiation element 3 is reflected by the mirror-processed surface, it is possible to further improve the irradiation efficiency of the ultraviolet L to the eyewear E.

In the above-described embodiment, the ultraviolet irradiator 1 including the pair of irradiation elements 3 arranged along the first direction D1 has been described. However, the number and arrangement of the irradiation elements 3 are not limited to the example of the ultraviolet irradiator 1. For example, one irradiation element may be arranged in a region including the center of the first direction D1, or an irradiation element may be further provided at a position facing each pad E9 in addition to the pair of irradiation elements 3. good.

In the above-described embodiment, the ultraviolet irradiator 1 provided with the convex positioning portion 5 protruding from the main surface 2b of the base 2 has been described. However, the shape of the positioning portion is not limited to the convex shape protruding from the main surface 2b of the base 2. The shape of the positioning portion may be any shape that can fix the position of a part of the eyewear. For example, a recess may be provided on the main surface 2b of the base 2, and the irradiation element 3 may be arranged on the bottom surface of the recess. In this case, it is possible to provide a positioning portion that does not protrude from the main surface 2b. .. As a specific example, a concave portion formed on the main surface 2b may be provided, and a positioning portion for positioning the eyewear by fitting the eyewear into the concave portion may be provided. Further, the positioning portion can be omitted, and instead of the positioning portion, for example, a cushion portion or a cloth-like portion interposed between the eyewear E and the eyewear case C may be provided. As a specific example, if the eyewear E is arranged in a cushion portion having a recess arranged so that the irradiation element 3 does not protrude inside the eyewear case C, the eyewear E is protected even if the positioning portion is not provided. It becomes possible. Further, a cushion portion or a cloth-like portion may be provided between the eyewear E and the base 2 (main surface 2b). In this case, the cushion portion or the cloth-like portion does not project the irradiation element 3. It may have a hole exposed by. As a result, the contact of the eyewear E with the irradiation element 3 can be suppressed, and the eyewear E can be protected by the cushion portion or the cloth-like portion.
