Atomizing assembly for use in an aerosol-generating system
An atomizing assembly includes a tubing section having an inlet end and an outlet end. The inlet end of the tubing section is connectable to a liquid storage portion, and the outlet end of the tubing section is in fluid communication with an atomizing nozzle. The tubing section is configured to deliver a flow of liquid aerosol-forming substrate through the atomizing nozzle. The atomizing nozzle includes an air channel configured to establish an air flow through the nozzle. The air flow is mixed with the flow of liquid aerosol-forming substrate.

an atomizing nozzle defining an air channel through the nozzle, the nozzle including,
an outlet opening and a central opening, the outlet opening being a ring-shaped outlet opening arranged radially outwardly from the central opening;
a tubing section having an inlet end and an outlet end, the tubing section configured to deliver a portion of an aerosol forming substrate to the atomizing nozzle via the outlet end such that an air flow from the air channel is mixed with the portion of the aerosol forming substrate during operation of the atomizing nozzle; and
a pump at the outlet end of the tubing section.
2. The atomizing assembly according to claim 1 , wherein the pump includes an electrically driven pump.
3. The atomizing assembly according to claim 1 , wherein the pump includes a motorized pump.
4. The atomizing assembly according to claim 1 , wherein the pump includes a manually operated pump.
5. The atomizing assembly according to claim 1 , further comprising:
a storage portion configured to hold the aerosol forming substrate, the storage portion being pressurized.
6. The atomizing assembly according to claim 1 , further comprising:
a one-way valve configured to control flow of the portion of the aerosol forming substrate through the tubing section.
7. The atomizing assembly according to claim 1 , further comprising:
a heater element, the heating element positioned with respect to the atomizing nozzle such that an atomized aerosol forming substrate sprayed from the atomizing nozzle is incident on the heater element.
8. An aerosol generating system comprising:
a housing;
an air inlet in the housing;
