## Abstract

Aspects of the instant disclosure relate to electronic cigarettes; more particularly, to electronic cigarettes including a clearomizer. Various embodiments of the present disclosure are directed to a clearomizer with a refillable electronic cigarette juice tank with a first fill aperture, and a mouthpiece including a second fill aperture. The mouthpiece and the refillable tank rotate relative to one another along a common longitudinal axis to align the fill apertures, and facilitate filling of the refillable tank.

## Claims

### Claim 1

An eCig clearomizer comprising:
a refillable tank comprising
a tank proximal portion and a tank distal portion,
a first fill aperture, and
a first annular channel around the proximal portion of the tank; and
a mouthpiece comprising
a mouthpiece proximal portion and a mouthpiece distal portion,
a second fill aperture,
a first annular protuberance around the distal portion of the mouthpiece,
wherein the first annular protuberance is slidably retained in the first annular channel to facilitate rotation of the mouthpiece relative to the refillable tank;
wherein the refillable tank and the mouthpiece are thereby configured and arranged to permit relative rotation to selectably align and misalign the first and second fill apertures.

### Claim 2 (depends on 1)

The clearomizer of claim 1, wherein the refillable tank and the mouthpiece are rotatably coupled by the first annular channel and the first annular protuberance such that the mouthpiece may be rotated relative to the refillable tank about a common longitudinal axis.

### Claim 3 (depends on 1)

The clearomizer of claim 1, wherein the refillable tank includes a first vent aperture, and the mouthpiece includes a second vent aperture; the mouthpiece further configured and arranged to rotatably align the first and second vent apertures concurrently with the alignment of the first and second fill apertures.

### Claim 4 (depends on 3)

The clearomizer of claim 3, wherein the fill and vent apertures are configured and arranged to facilitate filling of the refillable tank with the eCig juice.

### Claim 5 (depends on 3)

The clearomizer of claim 3, wherein the vent apertures of the refillable tank and the mouthpiece are configured and arranged to be rotatably alignable to alleviate pressure build up in the refillable tank associated with filling the refillable tank with the eCig juice.

### Claim 6 (depends on 3)

The clearomizer of claim 3, wherein the mouthpiece includes a nozzle, and an vapor chamber, the vapor chamber located between the nozzle and the second vent aperture.

### Claim 7 (depends on 6)

The clearomizer of claim 6, wherein the first and second vent apertures are configured and arranged, when rotatably aligned, to alleviate pressure build up in the refillable tank associated with filling the refillable tank with the eCig juice by exhausting the pressurized gas through the first and second vent apertures, into the vapor chamber, and out the nozzle.

### Claim 8 (depends on 1)

The clearomizer of claim 1, wherein the refillable tank further includes a pressure release valve.

### Claim 9

An eCig clearomizer comprising:
a refillable tank configured and arranged to contain eCig juice;
a heater coil configured and arranged to atomize eCig juice in response to a current draw across the heater coil;
a wick configured and arranged to draw the eCig juice from the refillable tank to the heater coil by capillary action; and
a mouthpiece coupled to a proximal portion of the refillable tank and configured and arranged to rotate relative to the refillable tank along a common longitudinal axis.

### Claim 10 (depends on 9)

The clearomizer of claim 9, wherein the refillable tank and the mouthpiece both include a fill aperture and a vent aperture, the fill and vent apertures configured and arranged to be rotatably alignable to facilitate filling of the refillable tank with the eCig juice.

### Claim 11 (depends on 10)

The clearomizer of claim 10, wherein the fill and vent apertures are further configured and arranged to be rotatably mis-alignable to prevent escape of the eCig juice from within the refillable tank.

### Claim 12 (depends on 10)

The clearomizer of claim 10, wherein the fill apertures of the refillable tank and the mouthpiece are configured and arranged, when rotatably aligned, to fluidly couple the refillable tank with an external environment for refilling the refillable tank with the eCig juice.

### Claim 13 (depends on 10)

The clearomizer of claim 10, wherein the vent apertures of the refillable tank and the mouthpiece are configured and arranged, when rotatably aligned, to alleviate pressure build up in the refillable tank associated with filling the refillable tank with the eCig juice.

### Claim 14 (depends on 10)

The clearomizer of claim 10, wherein the mouthpiece includes a nozzle, and a vapor chamber, the vapor chamber located between the nozzle and the mouthpiece vent aperture.

### Claim 15 (depends on 14)

The clearomizer of claim 14, wherein the vent apertures of the refillable tank and the mouthpiece are configured and arranged, when rotatably aligned, to alleviate pressure build up in the refillable tank, associated with filling the refillable tank with the eCig juice, by exhausting pressurized gas through the vent apertures and the vapor chamber, and out the nozzle.

### Claim 16

An eCig clearomizer comprising:
a hemicylindrical port including
fluid inlet, and
electrical pads, at least one of the electrical pads electrically coupled to a heater coil within the clearomizer; and
wherein the hemicylindrical port is configured and arranged to
electrically couple the heater coil with electrical circuitry of a power supply portion, and
transfer a fluid from the power supply portion to the clearomizer in response to a vacuum pressure within the clearomizer.

### Claim 17 (depends on 16)

The clearomizer of claim 16, wherein the at least one of the electrical pads are electrically coupled to memory circuitry within the clearomizer.

### Claim 18 (depends on 16)

The clearomizer of claim 16, wherein the electrical pads are located on a flat surface of the hemicylindrical port.

### Claim 19 (depends on 16)

The clearomizer of claim 16, wherein the hemicylindrical port is further configured and arranged to be mechanically and electrically coupled to a mating hemicylindrical port on a power supply portion of an eCig.

### Claim 20 (depends on 1)

The clearomizer of claim 1, further including complementary stopping features on both the mouthpiece and the refillable tank, the complementary stopping features configured and arranged to
limit the rotation of the refillable tank relative to the mouthpiece along a common longitudinal axis, and
provide at least one of an audible indication and a tactile indication in response to reaching the rotational limit of the refillable tank relative to the mouthpiece.
