Abstract

An atomization core provides a core body having a central channel, a first cylindrical portion having an outer diameter, and a second cylindrical portion having an outer diameter. The central channel extends through the first and second cylindrical portions, and the first cylindrical portion, the second cylindrical portion, and the central channel are aligned about a central axis. The outer diameter of the second portion is larger than the outer diameter of the first portion.

Claims (23)

1 . An atomization core, comprising:

a core body having a central channel, a first cylindrical portion having an outer diameter, and a second cylindrical portion having an outer diameter;

e-liquid guide cotton in direct contact with the outer diameter of the second cylindrical portion, but not in direct contact with the outer diameter of the first cylindrical portion;

a heating element embedded in the core body and spirally arranged around the central channel;

wherein the central channel extends through the first cylindrical portion and the second cylindrical portion;

wherein the first cylindrical portion, the second cylindrical portion, and the central channel are aligned about a central axis; and

wherein the outer diameter of the second portion is larger than the outer diameter of the first portion.

2 . The atomization core of claim 1 , wherein the core body comprises a microporous ceramic.

3 . The atomization core of claim 1 , wherein the core body comprises a generally cylindrical core body.

4 . The atomization core of claim 1 , wherein the central channel comprises two separate channels.

5 . The atomization core of claim 1 , further comprising a generally cylindrical ring disposed about the first cylindrical portion, wherein the ring includes an outer diameter equal to the outer diameter of the second cylindrical portion and an inner diameter configured to fit about the outer diameter of the first cylindrical portion.

6 . An atomization core, comprising:

a core body having a central channel, a first cylindrical portion having an outer diameter, and a second cylindrical portion having an outer diameter;

a generally cylindrical ring disposed about the first cylindrical portion;

wherein the central channel extends through the first cylindrical portion and the second cylindrical portion;

wherein the first cylindrical portion, the second cylindrical portion, and the central channel are aligned about a central axis;

wherein the outer diameter of the second portion is larger than the outer diameter of the first portion; and

wherein the ring includes an outer diameter equal to the outer diameter of the second portion and an inner diameter configured to fit about the outer diameter of the first cylindrical portion.

7 . The atomization core of claim 6 , further comprising a heating element embedded in the core body and spirally arranged about the central channel.

8 . The atomization core of claim 6 , wherein the core body comprises a microporous ceramic.

9 . The atomization core of claim 6 , wherein the core body comprises a generally cylindrical core body.

10 . The atomization core of claim 6 , wherein the central channel comprises two separate channels.

11 . The atomization core of claim 6 , further comprising e-liquid guide cotton in direct contact with the outer diameter of the second cylindrical portion, but not in direct contact with the outer diameter of the first cylindrical portion.
