## Abstract

An atomizer includes a liquid delivery element configured to absorb an aerosol generating material of a liquid storage and a wire configured to heat the aerosol generating material and wound on a surface of the liquid delivery element, wherein the wire is wound in a spiral shape such that coils of the wire are spaced apart from each other by a certain distance on the surface of the liquid delivery element, one of end portions of the wire is in contact with a first portion of the surface of the liquid delivery element, and the other one of the end portions of the wire is in contact with a second portion of the surface of the liquid delivery element.

## Claims

### Claim 1

An atomizer comprising:
a liquid delivery element configured to absorb an aerosol generating material contained in a liquid storage; and
a wire configured to heat the aerosol generating material and wound on a surface of the liquid delivery element,
wherein the wire is wound in a spiral shape such that coils of the wire are spaced apart from each other by a certain distance on the surface of the liquid delivery element,
wherein one of end portions of the wire is in contact with a first portion of the surface of the liquid delivery element, and the other one of the end portions of the wire is in contact with a second portion of the surface of the liquid delivery element, and
wherein at least one of the end portions of the wire comprises a ridge portion wound to be spaced apart from the liquid delivery element by a certain distance.

### Claim 2 (depends on 1)

The atomizer of claim 1, wherein the end portions of the wire point in a direction different from a direction of gravity.

### Claim 3 (depends on 1)

The atomizer of claim 1, wherein a top of the ridge portion is separated from the liquid delivery element by the certain distance.

### Claim 4 (depends on 3)

The atomizer of claim 3, wherein the certain distance ranges from 0.001 mm to 2 mm.

### Claim 5

A cartridge comprising:
a liquid storage configured to store an aerosol generating material; and
an atomizer configured to heat the aerosol generating material to generate aerosol,
wherein the atomizer includes:
a liquid delivery element configured to absorb the aerosol generating material; and
a wire configured to heat the aerosol generating material and wound on a surface of the liquid delivery element,
wherein the wire is wound in a spiral shape such that coils of the wire are spaced apart from each other by a certain distance on the surface of the liquid delivery element,
wherein one of end portions of the wire is in contact with a first portion of the surface of the liquid delivery element, and the other one of the end portions of the wire is in contact with a second portion of the surface of the liquid delivery element, and
wherein at least one of the end portions of the wire comprises a ridge portion wound to be spaced apart from the liquid delivery element by a certain distance.

### Claim 6 (depends on 5)

The cartridge of claim 5, wherein the end portions of the wire point in a direction different from a direction of gravity.

### Claim 7 (depends on 5)

The cartridge of claim 5, wherein a top of the ridge portion is separated from the liquid delivery element by the certain distance.

### Claim 8 (depends on 7)

The cartridge of claim 7, wherein the certain distance ranges from 0.001 mm to 2 mm.

### Claim 9 (depends on 1)

The atomizer of claim 1, wherein the end portions of the wire are disposed such that the aerosol generating material does not flow out of the wire through the end portions.

### Claim 10 (depends on 5)

The cartridge of claim 5, wherein the end portions of the wire are disposed such that the aerosol generating material does not flow out of the wire through the end portions.
