1, the portable water bottle according to an embodiment of the present invention, the water storage unit 110, water detection sensor 120, ultraviolet lamp 140, PCB substrate 150, storage battery 160 and the light collecting plate It can be seen that the configuration including the 180.

The water reservoir 110 may have a configuration that is the same as or similar to that of a water bottle for a conventional water bottle including a hollow body having an open top surface.

The water sensor 120 is positioned above the water storage unit 110 to detect whether water is present in the water storage unit 110. Natural liquid any sensor may be applied to the water sensor 120 is a matter of course.

When it is determined that the water is present in the water storage unit 110 by the water sensor 120, the control unit configured on the PCB substrate 150 drives the ultraviolet lamp 140 so that the water in the water storage unit 110 is stored. By irradiating ultraviolet rays (照射) it is possible to perform functions such as sterilization, disinfection, deodorization. Of course, the UV lamp 140 may be provided with any conventional lamp such as an LED lamp or a mercury lamp.

At this time, the power supply to the water sensor 120, the ultraviolet lamp 140 and the PCB substrate 150 may be made by the battery 160, the battery 160 is provided on the top surface of the stopper body 170 Through the function of receiving and storing the electricity generated by the light collecting plate 180 may be performed as a power source.
