(Embodiment 1)
Hereinafter, the sterilization container according to Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view of a sterilization container 1 according to Embodiment 1 of the present invention.

  In FIG. 1, a sterilization container 1 is disposed inside a container 2 that can store water, and kills microorganisms such as bacteria contained in the water when the container 2 is filled with water. A sterilizing device 3 for generating electric power, and an electric power generating device 4 for generating electric power and supplying the generated electric power to the sterilizing device 3. The term “sterilization” or “killing microorganisms” in this patent includes the meaning of “detoxifying microorganisms” in addition to the meaning of “killing microorganisms”.

  With this configuration, since the sterilization container 1 can be operated even when the sterilization container 1 is not supplied with electric power from the outside, the user can use the sterilization container 1 even in a place where the electric supply cannot be received. . Further, for example, when the user stays in an area where water supply facilities are not set for a long time or when a disaster occurs, even if the sterilization container 1 is used for a long time, there is no need to worry about running out of the battery. User convenience can be improved.

  Hereinafter, each structure of the sterilization container 1 is explained in full detail.

  The sterilization container 1 is a portable drinking container that kills microorganisms such as bacteria contained in water injected into the container 2. The sterilization container 1 is a substantially rotating body whose axis of rotation is a shaft 6 that connects the center of the bottom of the container 2 and the center of the drinking lid 5 that closes the drinking mouth of the container 2, but is not limited to this shape. The sterilization container may be, for example, a contact lens sterilization container, a baby bottle sterilization container, a denture sterilization container, a shaving sterilization container, or a toothbrush sterilization container, in addition to a drinking use for sterilizing drinking water stored in the container 2. May be. That is, the sterilization container 1 may be used for sterilizing a liquid (water or the like) for cleaning a certain object, or for sterilizing a liquid (water or the like) together with a certain object.

  The container 2 is made of a metal such as aluminum or stainless steel, or a resin such as polyethylene terephthalate, but any material can be used as long as it can accommodate a liquid. If the volume of the container 2 is about 1 milliliter to 5 liters, the user can shake the sterilization container 1 with his / her hand, and vibration power generation by the power generator 4 is possible. When the sterilization container 1 is used as a drinking container, user convenience is high when the volume of the container 2 is about 100 ml to 3 liters. Moreover, it is desirable that the water supply lid 19 including the drinking mouth of the container 2 (a substantially conical portion of the head of the container 2) be removable. In this way, by providing the drinking port of the container 2 and the water supply port 20 of the container 2 at different positions, it is not necessary for the user to put a mouth on the water supply port 20 to which water containing microorganisms may adhere. Hygienic.

The sterilizer 3 is an ultraviolet radiation device that emits ultraviolet light having a wavelength of 10 nm to 380 nm. The sterilizer 3 may be provided in the power generator 4 provided in the container 2 or may be fixed to the inner wall surface of the container 2. However, the sterilizer 3 is waterproofed to prevent water from entering the sterilizer 3 regardless of where it is provided in the container 2. In addition, it is desirable to use a light emitting diode that emits ultraviolet rays as the sterilizing device 3 from the viewpoint of impact resistance and durability, but other ultraviolet emitting devices such as a fluorescent lamp that emits ultraviolet rays may be used. When the wavelength of ultraviolet rays is 200 nm to 300 nm, ultraviolet rays have a high killing power against microorganisms. In particular, when the wavelength is from 250 nm to 260 nm, the killing power of ultraviolet rays against microorganisms has a maximum value. Among the microorganisms, fungi, spore fungi, Bacillus subtilis, Bacillus anthracis, etc. are highly resistant to ultraviolet rays. For example, when the ultraviolet wavelength is in the UV-C region, for example, the illuminance is 10 mW / cm ² for 10 seconds or more. When irradiated with ultraviolet light, most microorganisms in the water are killed. The sterilizer 3 may be other sterilizers such as an ultrasonic generator, a current generator, a heat generator, a fine bubble generator, and an electrolyzer.

  The power generation device 4 includes a vibration power generation unit 12 that generates power when the sterilization container 1 is shaken by a user. Microorganisms present in water relatively far from the sterilizer 3 have a higher survival probability than microorganisms present in relatively close water. In particular, when the sterilizer 3 is an ultraviolet radiation device, microorganisms present in water relatively far from the sterilizer 3 are highly likely to be hidden behind the microorganisms and not irradiated with ultraviolet rays. For example, when the sterilizer 3 is an electric current generator, the current is less likely to flow in water relatively far from the sterilizer 3, compared to water relatively close to the sterilizer 3, and the killing rate of microorganisms in the water Becomes lower. Therefore, when the user shakes the sterilization container 1 when generating electric power, the water in the container 2 is agitated, and the microorganisms existing in the water far from the sterilization apparatus 3 approach the sterilization apparatus 3, thereby killing the microorganisms in the water. Can be greatly increased. In other words, when power is generated to operate the sterilizer 3, the user can remember to stir the water, and the killing rate of the microorganisms in the water is greatly increased. Alternatively, the killing time of a predetermined proportion of microorganisms in water is shortened. In addition, since the flow of water continues for a while after the power generation by vibration is completed, the killing rate of the microorganisms in the water can be increased even after the vibration power generation is completed and during the operation of the sterilizer 3. In addition, since the straightness of ultraviolet rays is high, when the sterilizer 3 is an ultraviolet radiation device, stirring the water in the container 2 is particularly effective as means for increasing the killing rate of microorganisms in the water.

  Specifically, the power generation device 4 includes the vibration power generation unit 12 and the power supply circuit unit 13, and is provided at the bottom of the container 2 and further waterproofed. The vibration power generation unit 12 includes a first cylinder 7 fixed to the bottom of the container 2, a coil 8 wound around the first cylinder 7, a magnet 9 movable in the first cylinder 7, and a first And a lid 11 that covers the upper ends of the second cylinder 10, the first cylinder 7, and the second cylinder 10 made of a material having an ultraviolet transmittance of 90% or more. The first cylinder 7, the second cylinder 10, or the lid portion 11 may be made of glass, but a resin is desirable from the viewpoint of impact resistance. In addition, in addition to the second cylinder 10, when the first cylinder 7 is also made of a material having an ultraviolet transmittance of 90% or more, the irradiated area of the ultraviolet light in the water is widened to increase the killing rate of the microorganisms in the water. Can do. For example, when the first cylinder 7 and the second cylinder 10 are rotating bodies having the axis 6 as the central axis, the coil 8 moves along the axis 6. In such a configuration, the sterilizer 3 (ultraviolet radiation device) is disposed between the first cylinder 7 and the second cylinder 10. In order to prevent the coil 8 and the sterilizer 3 from being flooded, the lower end of the vibration power generation unit 12 is covered with the bottom of the container 2 so that the inside of the vibration power generation unit 12 is a sealed space. The shape of the magnet 9 may be a columnar shape having a bottom surface similar to a cross section perpendicular to the axis 6 of the first cylinder 7. When the cross section of the first cylinder 7 is circular, the shape of the magnet 9 may be spherical. Furthermore, friction between the magnet 9 and the first cylinder 7 may be reduced by putting lubricating oil between them. Further, the volume of the container 2 may be secured by providing the vibration power generation unit 12 in a handle (not shown) provided on the side surface of the container 2.

  As described above, the power generation device 4 desirably includes the vibration power generation unit 12 that generates power by electromagnetic induction from the viewpoint that the generated electromotive force is high. However, the power generation device 4 includes a vibration power generation unit that generates power based on other principles, such as a vibration power generation unit that generates power by changing capacitance or a vibration power generation unit that generates power by the piezoelectric effect. May be.

  As described above, when the power generation device 4 includes the vibration power generation unit, both the power generation by the vibration of the sterilization container 1 and the stirring of water are exhibited. However, the power generation device 4 may have other power generation means such as a solar power generation unit instead of the vibration power generation unit 12.

  Next, an example of an internal circuit of the power supply circuit unit 13 will be described with reference to FIG.

  For example, the power supply circuit unit 13 is connected to the vibration power generation unit 12 and rectifies the alternating current generated by the vibration power generation unit 12, and is connected to the rectification circuit unit 14 and output from the rectification circuit unit 14. A power storage unit 15 that stores electric power, a capacitor 16 that is connected to the rectifier circuit unit 14 and smoothes the current output from the rectifier circuit unit 14, and is connected between the vibration power generation unit 12 and the sterilizer 3 that is a light-emitting diode. And a switch 17 for switching the connection between the two. The power storage unit 15 is, for example, a lithium ion battery, but may be another type of battery or a capacitor having a large capacity such as an electric double layer capacitor. In addition, it is desirable that the power supply circuit unit 13 includes the power storage unit 15 because the sterilizer 3 can be continuously operated for a while after the vibration power generation unit 12 ends the power generation. If the power generated by the vibration power generation unit 12 is supplied to the sterilization device 3 as it is even if the power storage unit 15 is not provided, the sterilization device 3 can emit ultraviolet rays. Furthermore, the power supply circuit unit 13 may include a boosting unit (not shown) that increases the voltage.

  In addition, as shown in FIG. 3, the power supply circuit unit 13 includes a protection circuit unit 18 that suppresses a voltage output of a predetermined value or more to the sterilization device 3, which is protection of the sterilization device 3 (light emitting diode). Desirable from a viewpoint.

  The above description is an example of the power supply circuit unit 13 when the power generation device 4 includes the vibration power generation unit 12 and the sterilization device 3 is a light emitting diode, but the power generation device 4 includes a solar power generation unit. Needless to say, when the sterilizer 3 is another sterilizer, the power supply circuit unit 13 has a configuration different from the above.

  Hereinafter, the usage method of the sterilization container 1 of the said structure is demonstrated using FIG.

  The user opens the water supply lid 19, injects water into the container 2 from the water supply port 20 of the container 2, closes the water supply lid 19 and the drinking lid 5, and then puts a plurality of sterilization containers 1 in the direction of the axis 6 of the container 2. Vibrate once. As a result, the magnet 9 reciprocates in the first cylinder 7, and the coil 8 generates an induced electromotive force. The generated electric power is stored in the power storage unit 15. Thereafter, the user presses (turns on) the switch 17. As a result, the power storage unit 15 and the sterilization device 3 are energized, and the sterilization device 3 that has received power supply radiates ultraviolet rays, thereby killing microorganisms contained in the water. At this time, if the user vibrates the sterilization container 1 after pressing (turning on) the switch 17, the sterilization apparatus 3 also receives power supply from the vibration power generation unit 12 and radiates ultraviolet rays. Then, after a lapse of a predetermined time after the sterilizer 3 operates, the user can open the drinking lid 5 and drink safer water with less microorganisms such as bacteria from the drinking mouth of the container 2. That is, since the sterilization container 1 can be operated even if the sterilization container 1 is not supplied with electric power from the outside, the user can use the sterilization container 1 even in a place where the electric supply cannot be received. Become. Further, when the user stays in an area where water supply facilities are not provided for a long time, or when the user uses the sterilization container 1 for a long time, there is no need to worry about running out of the battery. Can be improved. Further, when the power generation device 4 includes the vibration power generation unit 12, both power generation by vibration of the sterilization container 1 and water agitation are achieved.

  When the sterilizer 3 is an ultraviolet radiation device, the sterilization container 1 includes a reflective film (not shown) that covers the inner wall surface of the container 2, and the reflectance of the reflective film in the ultraviolet wavelength region is the inner wall surface of the container 2. It is desirable that it be higher than the reflectance. As a result, since the reflective film reflects ultraviolet rays, the killing rate of microorganisms in the water increases, and ultraviolet rays are suppressed from radiating to the outside of the container 2, and ultraviolet rays are emitted to the user's eyes and skin. To prevent. In addition, even if the sterilization container 1 does not have a reflective film on the inner wall surface of the container 2, by making the container 2 a material or a structure that reflects 90% or more of ultraviolet rays on the inner side, the killing rate of microorganisms in water can be increased. While increasing, it suppresses that an ultraviolet-ray is radiated | emitted outside the container 2. FIG. For example, this effect can be enhanced if the inner wall surface of the container 2 is mirror-finished. Further, if the transmittance of the container 2 (or the reflective film attached to the container 2) in the visible light wavelength region is higher than the transmittance of the container 2 (or the reflective film attached to the container 2) in the ultraviolet wavelength region, the user can The water level can be confirmed visually, and ultraviolet rays can be prevented from being emitted to the user's eyes and skin.

  In addition, the sterilization container 1 preferably includes a notification unit 21 that emits at least one of sound and visible light during operation of the sterilizer 3. Thereby, the user can know that the sterilizer 3 is operating normally.

  Furthermore, when the notification unit 21 emits at least one of sound and visible light after a lapse of a predetermined time from the start of the operation of the sterilizer 3, the user can know that the killing rate of the microorganism has reached a predetermined level or more.

  Furthermore, as shown in FIG. 4, in the configuration in which the power generation device 4 includes the vibration power generation unit 12, the user can dispose the sterilization container 1 to generate power by providing the protrusion 22 on the inner wall surface of the container 2. The flow direction of the water in the container 2 when shaken is complicated. Thereby, the killing ratio of the microorganisms in water can be raised.
