Abstract

A portable water bottle includes a water bottle body having water stored therein; and a sterilizing module for irradiating the inside of the water bottle body with sterilizing ultraviolet rays. The sterilizing module further includes a housing having an ultraviolet outlet through which the sterilizing ultraviolet rays pass; a light source module for emitting the sterilizing ultraviolet rays; and a power storage member for supplying power to the light source module.

First claim

We claim:

1. A portable water bottle comprising:
a bottle body having a space storing water, the bottle body comprising:
a body coupling portion formed on an inner surface thereof; and
a breakaway prevention portion formed at an upper portion of the body coupling portion; and

a sterilizing module comprising:
a housing having a UV outlet through which sterilization UV light passes,
a light source module emitting the sterilization UV light, the light source module comprising a substrate and a sterilization light source disposed on the substrate and emitting the sterilization UV light; and
a power storage member supplying electric power to the light source module;
a window member disposed between the UV outlet and the light source module to divide an interior of the housing from an exterior of the housing; and
an interior sealing member configured and arranged to seal a gap between the UV outlet and the window member;

wherein the sterilizing module emits the sterilization UV light into the bottle body;
the body coupling portion is coupled to at least a portion of the sterilizing module; and
the breakaway prevention portion prevents the sterilizing module from being inserted into the bottle body by a predetermined depth or more;
a sensor operable to sense user gesture, operation of the bottle body or the sterilizing module, or a combination thereof; and
wherein the sterilization light source module emits sterilization UV light, or stops emission of the sterilization UV light depending on a sensing result of the sensor.

2. The portable water bottle according to claim 1 , wherein the sterilizing module is disposed at an upper portion or a lower portion of the bottle body.

3. The portable water bottle according to claim 1 , further comprising:
a window seat formed along a circumference of the UV outlet on an upper surface of the interior of the housing, the circumference of the UV outlet configured to receive the window member seated thereon.

4. The portable water bottle according to claim 3 , wherein the interior sealing member is disposed on the window seat and sealing the gap between the UV outlet and the window member.

5. The portable water bottle according to claim 4 , wherein a side surface of the window member is inserted into an inner surface of the interior sealing member to secure the window member to the interior sealing member.

6. The portable water bottle according to claim 4 , wherein the interior sealing member comprises:
a first interior sealing member disposed between the upper surface of the housing and the window member; and
a second interior sealing member disposed between the window member and the light source module.

7. The portable water bottle according to claim 1 , wherein the breakaway prevention portion is formed of a material allowing transmission of the sterilization UV light therethrough.

8. The portable water bottle according to claim 1 , wherein the breakaway prevention portion has a through-hole formed therein.

9. The portable water bottle according to claim 1 , wherein the body coupling portion comprises threads formed on the inner surface of the bottle body.

10. The portable water bottle according to claim 9 , further comprising:
a module coupling portion comprising threads formed on an outer surface of a portion of the housing inserted into the body coupling portion to couple the module coupling portion to the body coupling portion.

11. The portable water bottle according to claim 1 , further comprising:
an exterior sealing member disposed between the breakaway prevention portion and the sterilizing module and sealing a gap between the breakaway prevention portion and the sterilizing module.

12. The portable water bottle according to claim 1 , further comprising:
a connection terminal formed on the housing and connecting the power storage member to an external power source.

13. The portable water bottle according to claim 1 , wherein the sterilizing module further comprises a timer controlling a sterilization time.

14. The portable water bottle according to claim 1 , wherein the sterilizing module further comprises an input unit setting a sterilization time.

15. The portable water bottle according to claim 1 , wherein the sterilizing module further comprises an output unit outputting a sterilization start time, a sterilization stop time, a remaining sterilization time, or a combination thereof.

16. The portable water bottle according to claim 1 , wherein an inner wall of the bottle body is formed of a material preventing transmission of the sterilization UV light therethrough.

17. The portable water bottle according to claim 1 , wherein an inner wall of the bottle body comprises a material reflecting the sterilization UV light.

18. The portable water bottle according to claim 1 , wherein the power storage member is chargeable with electric power and comprises a first power storage member secured inside the sterilizing module, a second power storage member detachably secured to the sterilizing module, or both.

19. A sterilization module for use with a container comprising:
a housing having a UV outlet through which sterilization UV light passes, the housing arranged within a body of a container;
a light source module emitting the sterilization UV light into the body of the container, the light source module comprising a substrate and a sterilization light source disposed on the substrate and emitting the sterilization UV light; and
a power storage member supplying electric power to the light source module;
a window member disposed between the UV outlet and the light source module to divide an interior of the housing from an exterior of the housing;
an interior sealing member configured and arranged to seal a gap between the UV outlet and the window member; and
a sensor operable to sense user gesture, operation of the body of the container or the sterilizing module, or a combination thereof; and
wherein the sterilization light source emits sterilization UV light, or stops emission of the sterilization UV light depending on a sensing result of the sensor.

20. The sterilization module for the container of claim 19 , further comprising a power switch operable to send a start signal to the sensor,
wherein upon reception of a power start signal, the sensor generates a sterilization start signal or a sterilization stop signal, and
the sterilization start signal or the sterilization stop signal is correlated to the sensing result of the sensor;
wherein the sensor comprises a humidity sensor, a gyro sensor, a distance sensor, a gesture sensor or a motion sensor, an illuminance sensor, or a combination thereof.
