## Abstract

An aerosol forming component for volatilizing a liquid in an aerosol delivery device is disclosed. The aerosol forming component includes a first aerosol-forming member configured to be heated up to a first operating temperature and thereafter to a second higher operating temperature, and a second aerosol-forming member configured to be heated up to at least the first operating temperature as the first aerosol-forming member reaches the second higher operating temperature so that liquid volatilized from the two aerosol-forming members mix with one another.

## Claims

### Claim 1

An aerosol forming component for volatilizing a liquid in an aerosol delivery device, comprising:
a first aerosol-forming member controlled to be heated up to a first operating temperature and thereafter to a second higher operating temperature; and
a second aerosol-forming member controlled separated from the first aerosol-forming member to be heated up to reach the first operating temperature substantially at the same time as the first aerosol-forming member reaches the second higher operating temperature so that liquid volatilized from the first aerosol-forming member mixes with liquid volatilized from the second aerosol-forming member, wherein the first aerosol-forming member is located upstream of the second aerosol-forming member with respect to a flow of air through the aerosol delivery device in use, wherein the first and second aerosol-forming members each comprise a heater element and a wick, and wherein the heater element and the wick of each of the first and second aerosol-forming members are arranged in a common surface; further comprising: a housing comprising an air inlet and an air outlet; an aerosol chamber in fluid communication with the air inlet and the air outlet; a power source to which the first and second aerosol forming members are electrically connected; and a controller for controlling activation of the first and second aerosol-forming members.

### Claim 2 (depends on 1)

The aerosol forming component according to claim 1, wherein the first and second aerosol-forming members are configured to have different heating rates, such that by activating the first and second aerosol-forming members simultaneously, the first aerosol forming member reaches the second operating temperature substantially at the same time as the second aerosol-forming member reaches the first operating temperature.

### Claim 3 (depends on 1)

The aerosol forming component according to claim 1, wherein the first aerosol-forming member is activated prior to activation of the second aerosol-forming member such that the first aerosol forming member reaches the second operating temperature substantially at the same time as the second aerosol-forming member reaches the first operating temperature.

### Claim 4 (depends on 1)

The aerosol forming component according to claim 1, further comprising a liquid for volatilization, wherein the liquid comprises one or more substances which create or promote an aerosol upon reaching volatilization temperature.

### Claim 5 (depends on 1)

The aerosol forming component according to claim 1, wherein the liquid comprises nicotine.

### Claim 6 (depends on 4)

The aerosol forming component according to claim 4, wherein the liquid comprises one or more volatile acids.

### Claim 7 (depends on 4)

The aerosol forming component according to claim 4, wherein the aerosol generating means are volatilized from the first aerosol-forming member as the first aerosol-forming member reaches the second operating temperature and the one or more low boiling point fraction(s) are volatilized from the second aerosol-forming member when the second aerosol-forming member reaches the first operating temperature such that the one or more low boiling point fraction(s) settles on the aerosol generating means.

### Claim 8 (depends on 1)

An aerosol delivery device comprising an aerosol forming component according to claim 1.
