Abstract

A heating module includes a housing with an opening, and a PTC ceramic heating element arranged in the housing having an inner face facing toward the opening, an outer face facing away from the opening and two end faces connecting the inner and outer faces, wherein the inner face is at least partially matched to the opening.

First claim

The invention claimed is:

1. A heating module comprising:
a housing with an opening;
a PTC ceramic heating element arranged in the housing and having an inner face facing toward the opening, an outer face facing away from the opening and two end faces connecting the inner and outer faces; and
three contact elements matched to the shape of the PTC ceramic heating element,
wherein two contact elements are arranged on one end face of the PTC ceramic heating element, one contact element is arranged on the other end face of the PTC ceramic heating element, and the inner face is at least partially matched to the opening.

2. The heating module according to claim 1 , wherein the PTC ceramic heating element is fastened between the contact elements by a clamp.

3. The heating module according to claim 1 , wherein the contact elements are formed at least partially in an annular shape or at least partially in a U shape.

4. The heating module according to claim 1 , wherein the contact elements comprise connecting lugs protruding out of the housing for the electrical contact-connection.

5. The heating module according to claim 1 , wherein the end faces are at least partially beveled.

6. The heating module according to claim 1 , wherein the PTC ceramic heating element is formed with an annular shape.

7. The heating module according to claim 6 , wherein the PTC ceramic heating element is formed at least partially conically on the end faces.

8. The heating module according to claim 1 , wherein the PTC ceramic heating element is formed in a U shape.

9. The heating module according to claim 8 , wherein the PTC ceramic heating element has a smaller height on the inner face than on the outer face.

10. The heating module according to claim 1 , wherein the housing comprises at least two housing parts connected to one another by a latching connection.

11. The heating module according to claim 10 , wherein the at least two housing parts connect to a flanged inner sleeve.

12. The heating module according to claim 11 , wherein the inner sleeve is arranged at least partially in the opening in the housing.

13. A vaporization apparatus comprising a container, liquid-conducting element and the heating module according to claim 1 , wherein the liquid-conducting element protrudes into the heating module with one end and into the container with the other end.

14. The heating module according to claim 2 , wherein the contact elements are formed at least partially in an annular shape or at least partially in a U shape.

15. The heating module according to claim 2 , wherein the contact elements comprise connecting lugs protruding out of the housing for the electrical contact-connection.

16. The heating module according to claim 3 , wherein the contact elements comprise connecting lugs protruding out of the housing for the electrical contact-connection.
