Abstract

A sterilization module including a light source configured to irradiate ultraviolet light, a board on which the light source is mounted, a protective tube accommodating the board therein and configured to transmit ultraviolet light irradiated from the light source, a first base coupled to one side of the protective tube, and a second base coupled to the other side of the protective tube, in which at least one of the first base and the second base includes an insertion part to be inserted into the protective tube, the insertion part having a first diameter when viewed in a first cross-section perpendicular to a length direction of the protective tube, and a cover part integrally formed on the insertion part and having a second diameter greater than the first diameter in the first cross-section.

First claim

What is claimed is:

1. A sterilization module comprising:
a light source configured to irradiate ultraviolet light;
a board on which the light source is mounted;
a protective tube accommodating the board therein and configured to transmit the ultraviolet light irradiated from the light source;
a first base coupled to one side of the protective tube; and
a second base coupled to the other side of the protective tube,
wherein each of the first base and the second base includes:
an insertion part to be inserted inside the protective tube, the insertion part having a first diameter when viewed in a first cross-section perpendicular to a length direction of the protective tube; and
a cover part integrally formed with the insertion part as a single piece and having a second diameter greater than the first diameter in the first cross-section,

wherein the insertion part includes a protrusion that protrudes from an outer peripheral surface of the insertion part to have an O-ring shape, and
wherein at least a portion of the cover part directly contacts the protective tube.

2. The sterilization module of claim 1 , wherein a diameter of an outer peripheral surface of the protrusion is equal to or greater than a diameter of an inner peripheral surface of the protective tube.

3. The sterilization module of claim 1 , wherein the second diameter is the same as a diameter of an outer peripheral surface of the protective tube.

4. The sterilization module of claim 3 , wherein a difference between the second diameter and the first diameter is the same as a thickness of the protective tube.

5. The sterilization module of claim 1 , wherein the insertion part includes:
a fixation groove recessed from a surface of the insertion part, and into which the board is to be inserted and fixed; and
a receiving groove recessed from the surface of the insertion part, and connected to the fixation groove.

6. The sterilization module of claim 5 , wherein:
the insertion part further includes a withdrawal groove recessed from the surface of the insertion part and connected to the fixation groove;
the cover part has at least one through-hole; and
the withdrawal groove is connected to the at least one through-hole.

7. The sterilization module of claim 6 , wherein the fixation groove includes:
a first fixation groove, into which one side surface of the board is to be inserted and fixed; and
a second fixation groove, into which the other side surface of the board is to be inserted and fixed.

8. The sterilization module of claim 7 , wherein a depth at which the first fixation groove and the second fixation groove are recessed from the surface of the insertion part is shorter than a depth at which the receiving groove is recessed from the surface of the insertion part.

9. The sterilization module of claim 8 , wherein:
the one side surface and the other side surface of the board are respectively connected to the first fixation groove and the second fixation groove; and
the board and an inner side surface of the cover part are spaced apart by a predetermined distance.

10. The sterilization module of claim 9 , further comprising a connector electrically connected to the light source,
wherein a wire connected to the connector is drawn to an outside via the predetermined distance.

11. The sterilization module of claim 8 , wherein a depth at which the withdrawal groove is recessed from the surface of the insertion part is the same as a depth at which the receiving groove is recessed from the surface of the insertion part.

12. The sterilization module of claim 7 , wherein
the at least one through-hole is connected to the receiving groove.

13. The sterilization module of claim 7 , wherein:
at least one of the first base and the second base further comprises a coupling part formed integrally with the cover part and extending along a direction in which the board extends;
the cover part has a through-hole along the direction in which the board extends; and
when viewed with respect to an extension surface extending along the board, the extension surface is positioned between the through-hole and the coupling part.

14. The sterilization module of claim 13 , further comprising a connector electrically connected to the light source, wherein:
the connector is mounted on a back surface of the board; and
the light source is mounted on a front surface of the board.

15. The sterilization module of claim 7 , further comprising a connector electrically connected to the light source,
wherein each of the connector and the light source is mounted on a front surface of the board.

16. The sterilization module of claim 15 , wherein the connector is accommodated inside the receiving groove.

17. The sterilization module of claim 6 , wherein the cover part includes:
a first cover part connected to the withdrawal groove; and
a second cover part connected to the receiving groove, and
wherein a length of the second cover part extending along the board in a first direction is greater than a length in the first direction of the first cover part.

18. The sterilization module of claim 1 , wherein the protrusion is formed integrally with the insertion part and the cover part.

19. The sterilization module of claim 1 , wherein a cross-section of the protective tube is circular or polygonal.

20. The sterilization module of claim 1 , wherein the light source is formed in plural to emit ultraviolet light in different directions.

21. The sterilization module of claim 1 , wherein at least one of the first base and the second base further comprises a coupling part connected to the cover part to be coupled to an external device.

22. A sterilization module comprising:
a light source configured to irradiate ultraviolet light;
a board having a light emitting surface, on which the light source is mounted, and a back surface opposite to the light emitting surface;
a protective tube accommodating the board therein and configured to transmit ultraviolet light irradiated from the light source; and
first and second bases respectively provided to both ends of the protective tube,
wherein one end of the board is coupled to be inserted into a fixation groove of the first base and the other end of the board is coupled to be inserted into a fixation groove of the second base, such that top and bottom surfaces of each end of the board face an inner surface of the first base and the second base, respectively,
wherein the light emitting surface is spaced apart from a center of each of the first and second bases, when viewed in a first cross-section perpendicular to a length direction of the protective tube, and
wherein each of the first base and the second base further includes a receiving groove connected to the fixation groove, having a greater width than that of the fixation groove, and being further away from the center of each of the first and second bases in a direction perpendicular to the length direction than the fixation groove.

23. The sterilization module of claim 22 , wherein, when viewed in the first cross-section, a longest distance between the light emitting surface and an outer peripheral surface of the first base or the second base has a value different from a longest distance between the back surface and the outer peripheral surface of the first base or the second base.

24. The sterilization module of claim 23 , wherein, when viewed in the first cross-section, the
