Abstract
A vaporizer assembly includes a tube having a first end with an inlet opening and a second end with an outlet opening. The vaporizer assembly also includes a heater element configured to vaporize liquid aerosol-forming substrate. The heater element is at the second end of the tube. The first end of the tube is fluidly connectable with a liquid storage portion. When the first end of the tube is fluidly connected with the liquid storage portion, the liquid aerosol-forming substrate can flow from the liquid storage portion through the inlet opening into the tube. The outlet opening of the tube includes perforations having a width ranging from about 1 micrometer to about 500 micrometers.
Claims20
A vaporiser assembly for an aerosol-generating system, comprising:
- a tube having a first end including an inlet opening and a second end including an outlet opening;
- and
- a heater element configured to vaporize a liquid aerosol-forming substrate, the heater element at the second end of the tube, the first end of the tube being configured to be fluidly connectable with a liquid storage portion such that the liquid aerosol-forming substrate flows from the liquid storage portion through the inlet opening into the tube, the outlet opening of the tube and a portion of the tube between the outlet opening and the inlet opening including perforations.
An aerosol-generating system, comprising:
- a power supply;
- electric circuitry configured to control the power supply;
- a vaporiser assembly including;
- a tube having a first end including an inlet opening and a second end including an outlet opening, and
- a heater element configured to vaporize liquid aerosol-forming substrate, the heater element at the second end of the tube, the first end of the tube being configured to be fluidly connectable with a liquid storage portion such that the liquid aerosol-forming substrate flows from the liquid storage portion through the inlet opening into the tube, the outlet opening of the tube and the outlet opening of the tube and a portion of the tube between the outlet opening and the inlet opening including perforations including perforations;
- and
- a replaceable liquid storage portion fluidly connectable with the first end of the tube.
A method for manufacturing a vaporiser assembly for an aerosol-generating system, the method comprising:
- providing a tube having a first end with an inlet opening and a second end with an outlet opening, the first end of the tube configured to be fluidly connectable with a liquid storage portion such that a liquid aerosol-forming substrate flows from the liquid storage portion through the inlet opening into the tube;
- placing a heater element at the second end of the tube;
- and
- establishing the outlet opening of the tube and a portion of the tube between the outlet opening and the inlet opening as perforations.
