[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sterilizing device useful for sterilizing footwear and the like.

[0002]

[Prior Art]

 Since footwear such as slippers and leather shoes are usually used up to the limit of use, various problems often occur such that various bacteria are easily propagated on the inner surface of the toes, and this causes a strange odor.

[0003]

[Problems to be solved by the device]

 As a well-known means for preventing this, a spray capable of spraying a bactericidal / bactericidal agent, an insole containing a bactericidal / bactericidal agent, etc. are known. There is a drawback that the inner surface of footwear gets moistened by the sterilizing and disinfecting agent of 1. and the latter insole has a very weak bactericidal effect on parts other than the insole. In each case, sterilization should be satisfactory. I can't.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sterilizing apparatus capable of reliably and satisfactorily performing partial sterilization of the inner surface of a footwear or the like.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an optical fiber cable including an apparatus main body having a light source capable of emitting ultraviolet light, an optical fiber cable having one end connected to the apparatus main body for propagating light from the light source, and a light diffusing means. The sterilization device is composed of the irradiation head provided at the other end of the bull.

[0006]

[Action]

 For example, when the inner surface of footwear is sterilized by the sterilizing apparatus according to the present invention, the irradiation head may be opposed to the inner surface of the footwear, particularly the inner toe portion where various bacteria are easily propagated, and the light source may be turned on for a predetermined time in the same state. .. The light from the light source built into the main body of the apparatus is propagated through the optical fiber cable and is widely irradiated from the light diffusion means of the irradiation head.

The ultraviolet lamp 3 has a rod shape, and is horizontally arranged at the center of the upper side of the reflection plate 2 via a holder 3 a.

The control box 4 has a part of an electric circuit, which will be described later, built therein and is arranged on the front side of the machine room 1c. A power cord 4a is drawn into the control box 4 from the outside, and a sterilization switch 8 and a display lamp 9 are provided on the upper surface of the apparatus main body 1, which is the upper side thereof.

The connector 5 is for connecting the optical fiber cable 6 to the light guide port 1d of the apparatus main body 1, and has a threaded portion 5a at the lower end which is detachably screwed to the upper end of the light guide port 1d. Further, the rod-shaped lens 5b is provided on the upper side thereof.

The optical fiber cable 6 is of a single core type and is composed of an optical fiber 6a and a covering member 6b which covers the outside thereof. One end of the optical fiber cable 6 has the coating material 6b removed and is inserted into the upper end of the connector 5 so that the end face of the optical fiber 6a is in contact with the rod lens 5b.

The irradiation head 7 is for irradiating ultraviolet rays to a portion requiring sterilization, and has a concave lens 7a for light diffusion at its front end and a rod-shaped lens 7b at its rear side. The coating material 6b is removed from the other end of the optical fiber cable 6 and is inserted into the rear end of the irradiation head 7 so that the end face of the optical fiber 6a is in contact with the rod lens 7b. Further, a spring-biased seesaw-shaped clip 7c is provided on the peripheral surface of the irradiation head 7.

In the figure, 3 is an ultraviolet lamp, 8 is a sterilization switch, 9 is a display lamp, 11 is an AC commercial power source, 12 is a booster circuit, 13 is a timer circuit, 14 is a relay, and 15 is a relay contact. It The control box contains a booster circuit 12, a timer circuit 13, a relay 14 and a relay contact 15, and the booster circuit 12 is connected to a power supply code 4a.

In this electric circuit, the ultraviolet lamp 3 and the display lamp 9 are lit by closing the relay contact 15 for a predetermined time period, for example, several tens of minutes, which is set by the timer circuit 13 based on the pressing operation of the sterilization switch 8. Can be made

The method of use and operation of the sterilizer described above will be described below with reference to FIG. First, in the state shown in FIG. 1, the irradiation head 7 is pulled out from the housing hole 1f of the apparatus main body 1, and the irradiation head 7 is used by using the clip 7c so that the irradiation head 7 faces the inner toe portion as shown in FIG. 7 is attached to the mouth part of the slipper S. Then, the sterilization switch 8 on the apparatus body 1 side is pressed.

The ultraviolet lamp 3 and the display lamp 9 are turned on based on the pressing operation of the sterilization switch 8. The light of the ultraviolet lamp 3 is condensed on the convex lens 1e side by the reflection plate 2, and is incident on one end of the optical fiber 6a while being converged by the convex lens 1b and the rod lens 5b.

The light incident on one end of the optical fiber 6a propagates in the optical fiber 6a, is radiated from the other end to the rod-shaped lens 7b in the irradiation head 7, and is converged by the rod-shaped lens 7b and is incident on the concave lens 7a. .. The light incident on the concave lens 7a is diffused by the concave lens 7a, and is widely radiated toward the toe portion of the inner surface of the slipper S to sterilize the irradiated portion.

After a lapse of a predetermined time from the start of lighting of the ultraviolet lamp 3, the ultraviolet lamp 3 and the display lamp 9 are turned off, and when the display lamp 9 is turned off, the completion of sterilization is notified to the user. After the sterilization is completed, the irradiation head 7 is removed from the slipper S and is stored again in the storage hole 1f of the apparatus body 1.

There is an advantage that it can irradiate ultraviolet rays effectively and sterilize the same part surely and satisfactorily.

Further, since the optical fiber cable 6 is used for propagating the ultraviolet rays, the light of the ultraviolet lamp 3 can be propagated to the irradiation head 7 without loss and a high sterilizing power can be obtained.

Furthermore, the bendable optical fiber cable 6 allows the irradiation head 7 to be freely routed, and if the optical fiber cable 6 is extended, sterilization can be performed at a location away from the apparatus body 1. Become.

FIG. 7 shows another embodiment of the irradiation head. The irradiation head 7'shown in the figure is formed into a U-shape, and each end has a concave lens 7a 'for light diffusion and a rod-shaped lens (not shown). Further, a demultiplexer (not shown) such as a half mirror is arranged at a portion of the irradiation head 7 ′ where the optical fiber cable 6 is attached so that the demultiplexed light is guided to each rod-shaped lens. It has become. Further, the irradiation head 7'is provided with a spring-biased, seesaw-shaped clip 7c '.

This irradiation head 7'can be attached to one pair of slippers at the same time by using a clip 7c ', and irradiates the light diffused by the concave lens 7a' toward the toe portion of the inner surface of the slipper. The irradiated part can be sterilized.

The ultraviolet lamp exemplified in the above embodiment may have another shape such as a spherical shape, and a semiconductor laser having an output frequency in the ultraviolet range may be used as a light source. In addition, even if another core type cable is used as the optical fiber cable, or the light propagated by one cable is branched during the propagation and the light is emitted from a plurality of irradiation heads. Good. Further, the optical fiber cable may be bent and can be held in a bent state and is housed in a flexible tube so that the insertion position and direction of the irradiation head can be held by the flexible tube. Furthermore, the concave lens for light diffusion provided in the irradiation head may be replaced with a corrugated lens or the like that can obtain a similar diffusion effect.
