Abstract

It is provided a case (200) for an electronic smoking device (10). The case (200) comprises a primary receiving portion (101), adapted to receive an electronic smoking device (10) and a secondary receiving portion (102), adapted to receive a liquid cartridge (300), adapted to contain a liquid. Furthermore, the case (200) comprises a liquid channel system (110) for the transport of liquid within the case (200). Moreover, the case (200) comprises a pump system (120) with an actuation element (130), adapted to provide liquid from a liquid cartridge (300) received by the secondary receiving portion (102) to a liquid outlet (112) of the liquid channel system (110) via the liquid channel system (110) upon an actuation of the actuation element (130).

First claim

The invention claimed is:

1. A case for an electronic smoking device, the case comprising:
a primary receiving portion, adapted to receive an electronic smoking device;
a secondary receiving portion, adapted to receive a liquid cartridge, adapted to contain a liquid;
a liquid channel system for the transport of liquid within the case, the liquid channel system comprising
a liquid inlet, adapted to be connected to a liquid cartridge received by the secondary receiving portion,
a liquid outlet, and
a liquid channel component, interconnecting the liquid inlet and the liquid outlet;

a pump system with an actuation element, wherein the actuation element comprises a rotatable pump wheel being accessible from an outside of the case and is adapted to provide liquid from a liquid cartridge received by the secondary receiving portion to the liquid outlet via the liquid channel system upon an actuation of the actuation element.

2. The case of claim 1 , wherein the pump system comprises an air channel system and an air suction reservoir arranged within the case, the air suction reservoir being connectable to an electronic smoking device received by the primary receiving portion via the air channel system.

3. The case of claim 2 , wherein the air suction reservoir comprises a plunger component, the plunger component having a plunger that is arranged movably within the air suction reservoir and a threaded rod attached to the plunger, wherein the threaded rod is protruding from a front portion of the air suction reservoir, wherein the front portion is facing the secondary receiving portion.

4. The case of claim 3 , wherein the rotatable pump wheel comprises an internal screw thread arranged in engagement with the threaded rod, wherein the threaded rod with the plunger attached thereto is pulled or pushed within the air suction reservoir depending on the direction of rotation of the rotatable pump wheel.

5. The case of claim 4 , further comprising a liquid cartridge received by the secondary receiving portion, the liquid cartridge comprising
a cartridge outlet, connected to the liquid inlet, and
an integrated slider portion which is configured slidable along the inner sides of the walls of the liquid cartridge, the integrated slider portion being arranged and configured to be moved by a front portion of the threaded rod protruding from the air suction reservoir.

6. The case of claim 5 , wherein the integrated slider portion and/or the plunger comprises at least one ring-shaped gasket element.

7. The case of claim 1 , wherein the primary receiving portion comprises an elongated cavity, adapted to enclose an electronic smoking device along its entire length L, the cavity comprising a primary opening on a first side of the case, wherein the primary opening is closeable via a slidable locking element arranged on or adjacent to the first side of the case.

8. The case of claim 2 , further comprising a connection interface connectable to the liquid outlet of the liquid channel system, wherein the connection interface is configured movably between a first and a second position, the connection interface comprising a first and a second hollow needle element, each adapted to be inserted into a corresponding refill interface of an electronic smoking device received by the primary receiving portion.

9. The case of claim 8 , wherein the first hollow needle element is connected to the air channel system, adapted to transport air from the first hollow needle element to the air suction reservoir.

10. The case of claim 8 , wherein a flow of liquid from the liquid inlet of the liquid channel system to the second hollow needle element is enabled when the connection interface is in the first position and wherein the flow of liquid from the liquid inlet of the liquid channel system to the second hollow needle element is reduced or interrupted when the connection interface is in the second position.

11. The case of claim 8 , wherein the first and the second needle element protrude into the primary receiving portion when the connection interface is in the first position and wherein the first and the second needle element are retracted from the primary receiving portion when the connection interface is in the second position.

12. The case of claim 8 , further comprising a lever element that is connected to the connection interface and accessible from outside of the case, wherein the connection interface is moveable between the first and the second position upon an actuation of the lever element.

13. The case of claim 12 , further comprising a locking system, the locking system being coupled to the lever element and adapted to prevent or reduce a supply of liquid to the second hollow needle element of the connection interface when the connection interface is in the second position.

14. The case of claim 13 , wherein the locking system comprises a first blocking element, the first blocking element being adapted to interact with the liquid channel component when the connection interface is in the second position, thereby blocking a flow of liquid to the second needle element.

15. The case of claim 13 , wherein the locking system further comprises a second blocking element configured to prevent an actuation of the actuation element of the pump system when the connection interface is in the second position.
