## Abstract

An electronic cigarette including a liquid supply, an air inlet, an inhalation port, and an atomizer. The liquid supply has a housing with a spiral container, having an outlet for directing a liquid held within the container out to the atomizer and at least one inlet sealed by a sealing agent to impede movement of the liquid. An air channel leads from the air inlet through the atomizer to the inhalation port for directing an aerosol generated at the atomizer to the inhalation port.

## Claims

### Claim 1

A liquid supply for an electronic smoking device comprising;
a spiral liquid container having a first end and a second end;
an outlet at the second end of the spiral liquid container;
liquid in the spiral liquid container;
a sealing agent in the spiral liquid container, the liquid between the sealing agent and the outlet, and the sealing agent movable within the spiral liquid container; and
the outlet of the spiral liquid container on a surface of the air channel.

### Claim 2 (depends on 1)

The liquid supply of claim 1 including an air channel extending centrally through the spiral liquid container.

### Claim 3 (depends on 1)

The liquid supply of claim 1 further including a housing, with the spiral liquid container insertable into and removable from the housing.

### Claim 4 (depends on 3)

The liquid supply of claim 3 further including a filler material or a sealant in a space between the spiral liquid container and a wall of the housing.

### Claim 5 (depends on 1)

The liquid supply of claim 1 further including an atomizer positioned to receive liquid from the outlet of the liquid container; and wherein the sealing agent moves through the spiral liquid container by capillary action as the liquid is consumed.

### Claim 6 (depends on 3)

The liquid supply of claim 3 with the spiral liquid container having an inlet at the first end of the housing.

### Claim 7 (depends on 5)

The liquid supply of claim 5 with the atomizer having a heating element in contact with liquid from the liquid container.

### Claim 8 (depends on 1)

The liquid supply of claim 1 wherein the sealing agent comprises grease.

### Claim 9 (depends on 8)

The liquid supply of claim 8 wherein the grease comprises a lithium based grease having a viscosity of about 4200˜4600 cs at 25 degrees Celsius.

### Claim 10

A liquid supply for an electronic smoking device comprising:
a housing;
an air channel in the housing connecting an air inlet to an inhalation port;
an atomizer and a liquid container in the housing, the liquid container including first and second spiral containers, with each spiral container containing a liquid;
each spiral container having an inlet and an outlet; and
each inlet sealed by a sealing agent movable through the spiral container, the sealing agent having a viscosity higher than the liquid.

### Claim 11 (depends on 10)

The liquid supply of claim 10 wherein the spiral containers are parallel to each other.

### Claim 12 (depends on 10)

The liquid supply of claim 10 wherein the inlet of each spiral container is at a first end of the housing, and the outlet of each spiral container is at a second end of the housing opposite from the first end of the housing.

### Claim 13 (depends on 10)

The liquid supply of claim 10 wherein the inlets of the spiral containers are at a first end of the housing, and the outlets of the spiral containers lead into the air channel.

### Claim 14 (depends on 10)

The liquid supply of claim 10 wherein the spiral containers are wound around the air channel.

### Claim 15 (depends on 10)

The liquid supply of claim 10 wherein the sealing agent is lithium based grease.

### Claim 16 (depends on 10)

The liquid supply of claim 10 further including a partition wall between the first and second spiral containers.

### Claim 17

A liquid supply for an electronic smoking device comprising;
a housing;
a spiral liquid container having a first end and a second end, the spiral liquid container insertable into and removable from the housing;
an outlet at the second end of the spiral liquid container;
liquid in the spiral liquid container;
a sealing agent in the spiral liquid container, the liquid between the sealing agent and the outlet, and the sealing agent movable within the spiral liquid container; and
a filler material or a sealant in a space between the spiral liquid container and a wall of the housing.
