E-vaping device
Example embodiments relate to a cartomizer including a housing, a fluid reservoir, configured to store an e-fluid, in the housing, a vaporizer configured to vaporize the e-fluid, the vaporizer including a heater having at least one end portion connected to an electrical lead wire, and a sleeve covering the connection between the end portion of the heater and the electrical lead wire.
1. A cartomizer, comprising:
a housing including an outer tube and an inner tube within the outer tube, the outer tube and the inner tube defining a fluid reservoir configured to store an e-fluid;
a vaporizer including a heater surrounding a wick, the heater having at least one end portion connected to an electrical lead wire via a connection within the fluid reservoir, the wick configured to draw the e-fluid from the fluid reservoir to the heater, the heater configured to vaporize the e-fluid; and
at least one sleeve within the fluid reservoir and covering the connection, the at least one sleeve surrounding the connection such that a portion of the at least one sleeve is between the connection and the inner tube, the at least one sleeve disposed between the outer tube and the inner tube and without touching the wick, a diameter of the at least one sleeve being less than a diameter of the inner tube, the at least one sleeve configured to cover the connection so as to avoid or reduce a reaction between the connection and the e-fluid.
2. The cartomizer according to claim 1 , wherein the connection between the at least one end portion of the heater and the electrical lead wire is formed by crimping.
3. The cartomizer according to claim 1 , wherein the connection between the at least one end portion of the heater and the electrical lead wire is formed by soldering.
4. The cartomizer according to claim 1 , wherein the connection between the at least one end portion of the heater and the electrical lead wire is formed by spot welding.
5. The cartomizer according to claim 1 , wherein
the inner tube includes a pair of opposing slots, and
the at least one end portion of the heater extends through one of the pair of opposing slots.
6. The cartomizer according to claim 5 , wherein the at least one sleeve is upstream from the pair of opposing slots of the inner tube relative to a flow of a vapor through the inner tube.
7. The cartomizer according to claim 5 , wherein
the e-fluid is a liquid material.
8. The cartomizer according to claim 1 , wherein
the at least one end portion of the heater is in a form of two end portions connected to two electrical lead wires via two connections; and
the at least one sleeve is in a form of two sleeves covering the two connections between the two end portions of the heater and the two electrical lead wires.
9. An e-vaping device, comprising:
a cartomizer including,
a housing including an outer tube and an inner tube within the outer tube, the outer tube and the inner tube defining a fluid reservoir configured to store an e-fluid,
a vaporizer including a heater surrounding a wick, the heater having at least one end portion connected to an electrical lead wire via a connection within the fluid reservoir, the wick configured to draw the e-fluid from the fluid reservoir to the heater, the heater configured to vaporize the e-fluid, and
at least one sleeve within the fluid reservoir and covering the connection, the at least one sleeve surrounding the connection such that a portion of the at least one sleeve is between the connection and the inner tube, the at least one sleeve disposed between the outer tube and the inner tube and without touching the wick, a diameter of the at least one sleeve being less than a diameter of the inner tube, the at least one sleeve configured to cover the connection so as to avoid or reduce a reaction between the connection and the e-fluid; and
a power supply configured to supply power to the heater.
10. The e-vaping device according to claim 9 , wherein the connection between the at least one end portion of the heater and the electrical lead wire is formed by crimping.
11. The e-vaping device according to claim 9 , wherein the connection between the at least one end portion of the heater and the electrical lead wire is formed by soldering.
12. The e-vaping device according to claim 9 , wherein the connection between the at least one end portion of the heater and the electrical lead wire is formed by spot welding.
13. The e-vaping device according to claim 9 , wherein
the inner tube includes a pair of opposing slots, and
the at least one end portion of the heater extends through one of the pair of opposing slots.
14. The e-vaping device according to claim 13 , wherein
the e-fluid is a liquid material.
15. The e-vaping device according to claim 13 , wherein
the at least one end portion of the heater is in a form of two end portions connected to two electrical lead wires via two connections; and
the at least one sleeve is in a form of two sleeves covering the two connections between the two end portions of the heater and the two electrical lead wires.
16. The e-vaping device according to claim 9 , wherein the power supply is removably connected to the cartomizer via a connector.
