Abstract

The invention relates to an inhaler component for forming a vapor-air mixture and/or condensation aerosol by vaporizing a liquid material and optionally condensing the vapor formed, including: a heating element for vaporizing a portion of the liquid material; a wick for automatically supplying the liquid material to the heating element, wherein the wick comprises at least two end sections arranged apart from each other; a first capillary gap for automatically supplying the liquid material to the wick, wherein a first end section of the wick projects into the first capillary gap. In order that the heating element can be supplied more quickly and more reliably with the liquid material, a second capillary gap is provided, which receives therein the second end section of the wick.

First claim

The invention claimed is:

1. An inhaler component comprising:
a mouthpiece;
a heating element configured to evaporate a portion of a liquid material;
a liquid container for retaining the liquid material, the liquid container comprising a valve positioned on an interior face of the inhaler component, wherein the valve seals the liquid material within the liquid container; and
a wick configured to automatically supply the liquid material to the heating element.

2. The inhaler component according to claim 1 , wherein the valve hermetically seals the liquid within the liquid container.

3. The inhaler component according to claim 1 , wherein the valve is located on a front face of the liquid container.

4. The inhaler component according to claim 1 , wherein the valve has a material weakening around its periphery.

5. The inhaler component according to claim 1 , wherein the valve forms a hinge on one side.

6. The inhaler component according to claim 1 , wherein the valve is openable like a flap.

7. The inhaler component according to claim 1 , further comprising a gap configured to automatically supply the wick with the liquid material, wherein the gap is a capillary gap and is further configured to automatically resupply the wick with the liquid material after evaporation.

8. The inhaler component according to claim 7 , further comprising a laminar composite including the heating element and the wick, and configured such that liquid in the gap is transferred to the wick via an end section of the laminar composite.

9. The inhaler component according to claim 7 , wherein the wick includes a first end section, a second end section, and an intermediate section between the first end section and the second end section, the gap configured to supply the liquid material to at least a portion of at least one of the first end section, the second end section, and the intermediate section.
