The UV light source is used for various purposes such as medical purposes such as sterilization and disinfection, analysis purpose using the irradiated UV light, industrial purpose of UV hardening, cosmetic purpose of UV tanning,

Conventional UV light source lamps used as such UV light sources include mercury lamps, excimer lamps, and deuterium lamps. However, all of these conventional lamps have a problem of power consumption, heat generation, short life span, and environmental pollution due to toxic gas filling the interior.

In order to solve the problem of the above-mentioned conventional UV light source lamps, UV LEDs have been receiving the spotlight. The UV LED has the advantages of low power consumption and no environmental pollution problem.

In particular, UV LEDs can be made small and can be used for various purposes because of their low power consumption.

Meanwhile, as the penetration rate of smartphones has increased, users of smartphones have been using earphones more and more, and the number of users wearing earphones is increasing. Since the earphone is inserted directly into the auricle, it comes into contact with sebum, dust and the like coming out from the earlobe or ear, and thus the contamination is easily done. Especially in recent years, since the earphones are almost closed, the contaminated earphones are likely to move into the ear when the earphones are put on the ear for a long time. As a result, the number of users suffering from ear diseases is increasing.

Conventionally, ultraviolet sterilizers for sterilizing smartphones and the like have been widely used. Most of them are fixed sterilizers having large volume, and portable ultraviolet sterilizers having a size to carry are not widely commercialized yet. However, as UV LEDs have been commercialized recently, low power and miniaturization of such sterilizers have become possible, and many sterilizers employing UV LEDs have been developed by taking advantage of these advantages.

In the case of the earphone, it is not necessary to sterilize the whole constitution of the earphone, and it is enough if the sterilization is mainly performed on the part mainly in direct contact with the ear. However, since the conventional sterilizer needs to put the earphone in its entirety, unnecessary parts of the cable are irradiated with ultraviolet rays, resulting in problems of discoloration and hardening.

Fig. 1 is a perspective view showing a state in which an opening and closing part of an earphone sterilizing device is opened as a first embodiment according to the present invention, Fig. 2 is a perspective view of an earphone sterilizing device of Fig. Fig.

As shown in FIG. 1, the earphone sterilizing apparatus according to the present invention includes a housing 10 in which an earphone can be embedded, and a cover unit 20 mounted on the housing.

As shown in FIGS. 1 and 2, the cover part 20 includes a fixing part 22 fixedly formed with respect to the housing 10, an opening / closing part 22 provided to the housing 10 to the fixing part 22, (24). On the inner surface of the upper center of the fixing portion 22, a UV LED 23 is provided in a direction to illuminate the lower portion. The opening and closing part 24 is rotated based on a horizontal hinge axis located at the upper middle part of the housing 10 to open or close the sterilizing space defined by the housing 10 and the cover part 20. [ The opening / closing portion is configured to pivot in the direction of the housing as shown in the figure, and the housing is shaped so as not to interfere with the rotation of the opening and closing portion, and a groove or the like may be formed if necessary. In addition, the fixing portion 22 is provided with an earphone passage hole 26, and one side of the earphone passage hole has a shape turned to a space opened by the opening / closing portion as shown in the figure. The earphone through hole is larger than the cable width of the earphone and smaller than the earphone main body 42. According to the first embodiment, the earphone passage hole is formed at the upper end of the fixing portion, and the earphone cable 44 is inserted without any resistance through the side portion.

On the upper surface of the housing 10, an earphone holder 30 capable of receiving an earphone is provided as shown in Fig. Further, the housing 10 is provided with a hollow space therein, and a cable winding portion 50 for winding the earphone cable 44 is provided in this space, so that the earphone cable is wound. The cable winding portion 50 may be manually wound around the winding shaft to wind the cable, or the cable may be automatically wound using a spring spring to be described later.

A cable is also drawn to the lower end of the housing 10 and an earphone connection jack 46 is formed at the end of the cable.

Therefore, the user opens the opening / closing part 24 as shown in Fig. 1, pulls out the earphone from the sterilizing space isolated from the outside by the housing 10 and the cover part 20 as shown in Fig. 3, 2, an earphone can be used by closing the opening / closing part 24 after passing the earphone cable through the earphone passage hole 26 as shown in FIG. 2 (in FIGS. 2 and 3, Lt; / RTI >

In this state, even when the earphone is inadvertently operated and is wound into the housing, the earphone passing hole is smaller than the earphone main body 42, so that the earphone does not completely enter the sterilizing space, As shown in FIG. Therefore, the user can simply pull the earphone main body again to withdraw the earphone.

When the user uses the earphone again and then stores the earphone in the earphone holder 30, the earphone main body 42 is pulled into the seating groove 32 of the earphone holder 30 by pulling the cable into the housing through the cable winding part 50 Come in.

The slot 12 is formed vertically communicating from the housing 10 to a certain portion A of the fixing portion 22 and a slot B corresponding to a slot formed in the fixing portion is formed in the opening and closing portion (See FIGS. 9 and 10A and 10B), when the earphone receiving holes are formed in the slots in the fixing part and the opening and closing part, the earphone receiving part is pulled up When the slider is lifted, only when the positions of the earphone passage holes of the fixed portion and the opening and closing portion are matched and the slots of the fixed portion and the opening and closing portion are made to coincide with each other, the slider can be moved along the two slots A and B It is also possible to configure.

[Structure of Cable Winding Section]

FIG. 12 is an exploded perspective view of a cable winding portion of an earphone sterilizing device according to the present invention, and FIG. 13 is a side sectional view of a winding roll for explaining the operation of the winding portion and the winding portion of the cable winding portion of FIG.

12, in the cable winding portion 50 of the present invention, a certain portion of the earphone cable is fixed to the winding roll 53 for winding the earphone cable 44, and when the winding roll 53 is wound When the cable 44 is wound along the outer periphery thereof and the winding roll is loosened, the cable wound along the outer periphery thereof is released. At this time, it is also possible to form the cable in a flat shape (so-called knife shape) so as to prevent the twist.

One end of the winding roll 53 is provided with a groove, in which the center hook of the spring is fitted. The spring of the winding spring elastically supports the winding roll in a direction in which the cable of the earphone is wound on the winding roll.

A tooth 55 is formed around the other end of the winding roll 53. A stopper 56 is provided around the tooth to catch or release the jam. The stopper does not rotate with respect to the rotating direction of the winding roll, but is reciprocating only in the axial direction of the winding roll (see Fig. 13). When the stopper 56 is engaged with the teeth 55, the winding roll 53 is rotatable only in the direction of unwinding the earphone cable (see Fig. 13 (a)), And when it is not biting, the whip roll can be rotated in both directions. 13, since the stopper 56 is elastically supported by a spring provided on the winding roll in the direction of engaging with the teeth, the stopper and the teeth are normally engaged with each other (see FIG. 13A) The user must push the release button (not shown) in a direction that does not engage the teeth with the stopper while pulling the elastic force of the spring (refer to FIG. 13 (b) do.
