Sterilization apparatus having ultraviolet light

1. A sterilization apparatus having UV light adapted to being assembled to a container with a liquid therein, comprising:

a body, detachably assembled to an opening of the container, so as to be in contact with the liquid in the container;

a light-emitting component, disposed on the body and emits UV light to irradiate the liquid in the container; and

a heat dissipation component, disposed in the body and thermally coupled to the light-emitting component, wherein part of the heat dissipation component is exposed from the body so as to contact the liquid in the container, and the heat dissipation component comprises a first end portion connected directly to the light-emitting component and a second end portion directly contacting the liquid.

2. The sterilization apparatus having UV light as claimed in claim 1 , further comprising:

a switch component, disposed on the body and electrically coupled to the light-emitting component, wherein when the body is assembled to the opening of the container, the container actuates the switch component.

3. The sterilization apparatus having UV light as claimed in claim 2 , further comprising:

a controller, disposed on the body, electrically coupled to the switch component and the light-emitting component and configured to control the light-emitting component to emit the UV light; and

a sensing module, disposed on the body and electrically coupled to the controller.

4. The sterilization apparatus having UV light as claimed in claim 3 , wherein the sensing module comprising a motion sensor so as to detect the inclination state of the body after being assembled to the container.

5. The sterilization apparatus having UV light as claimed in claim 4 , wherein the motion sensor further comprising a gravity sensor.

6. The sterilization apparatus having UV light as claimed in claim 4 , wherein the motion sensor comprises an orientation sensor.

7. The sterilization apparatus having UV light as claimed in claim 3 , wherein the sensing module comprises a liquid sensor so as to detect whether the liquid is stored in the container.

8. The sterilization apparatus having UV light as claimed in claim 3 , wherein the sensing module comprises a liquid level sensor so as to detect liquid level in the container.

9. The sterilization apparatus having UV light as claimed in claim 1 , further comprising:

a positioning component, connected to the body, the body is located between the positioning component and the light-emitting component, the positioning component having at least a positioning portion located at a side of the body, and when the body is assembled to the opening of the container, part of the container close to the opening is disposed between the positioning portion and the body.

10. The sterilization apparatus having UV light as claimed in claim 1 , further comprising:

a transparent cover, covering a recess of the body, wherein the light-emitting component is located in the recess and the UV light emitted by the light-emitting component is adapted to pass through the transparent cover so as to radiate the liquid in the container.

11. The sterilization apparatus having UV light as claimed in claim 1 , wherein a ratio between a surface area of the first end portion exposed in the recess and an area where the light-emitting component being in contact with the first end portion is less than 20.

12. The sterilization apparatus having UV light as claimed in claim 1 , wherein a ratio between an area where the body being in contact with the liquid and an area where the second end portion being in contact with the liquid is less than 20.
