Aerosol-generating system with separate capsule and vaporizer

Abstract

An aerosol-generating system may include a capsule and a releasably connectable vaporizer or vaporizing unit. The capsule comprises a distal end and defines a reservoir configured to contain an aerosol-generating substrate. The vaporizing unit comprises a housing and a heating element and a transfer element disposed in the housing. The heating element is configured to heat the transfer element to vaporize the aerosol-generating substrate. The housing of the vaporizing unit has a proximal end. A portion of the transfer element extends beyond the proximal end of the housing. The vaporizing unit is configured such that the transfer element is the initial part of the vaporizing unit to penetrate into the reservoir of the capsule as the distal end of the capsule is moved towards the proximal end of the vaporizing unit.

1 . An aerosol-generating system comprising:
 a capsule defining a reservoir for an aerosol-generating substrate, the capsule configured to reversibly transition between a default retaining state and an actuated releasing state with regard to the aerosol-generating substrate;   a vaporizer configured to connect with the capsule to transition the capsule to the actuated releasing state and to disconnect from the capsule so as to return the capsule to the default retaining state, the vaporizer includes a housing and a transfer element, the housing including a connecting member at least partially defining an aerosol passage, the transfer element having a first end section and a second end section each configured to fluidically communicate with the reservoir in the actuated releasing state; and   a cover configured to surround the capsule and the vaporizer, the cover including a spring configured to bias the capsule toward the vaporizer.   
     
     
         2 . The aerosol-generating system of  claim 1 , wherein the reservoir is configured to retain a liquid as the aerosol-generating substrate. 
     
     
         3 . The aerosol-generating system of  claim 1 , wherein the vaporizer further includes a heating element positioned in the aerosol passage. 
     
     
         4 . The aerosol-generating system of  claim 1 , wherein the first end section, the second end section, and the connecting member are aligned along a common axis of a cross-section of the vaporizer. 
     
     
         5 . The aerosol-generating system of  claim 1 , wherein the reservoir includes a high retention material in the reservoir. 
     
     
         6 . The aerosol-generating system of  claim 5 , wherein the high retention material is configured to be penetrated by the first end section and the second end section of the transfer element. 
     
     
         7 . The aerosol-generating system of  claim 6 , wherein the first end section and the second end section of the transfer element are configured such that the first end section and the second end section do not extend beyond the high retention material. 
     
     
         8 . The aerosol-generating system of  claim 2 , wherein
 the reservoir includes a first reservoir and a second reservoir, the first reservoir and the second reservoir being separated by the aerosol passage.   
     
     
         9 . The aerosol-generating system of  claim 8 , wherein the liquid retained within the first reservoir and the liquid retained within the second reservoir are different. 
     
     
         10 . The aerosol-generating system of  claim 8 , wherein the first reservoir is configured to be releasably culpable to the vaporizer independent of the second reservoir. 
     
     
         11 . The aerosol-generating system of  claim 1 , wherein the capsule includes a valve engaged with the reservoir, and the valve includes a resilient member configured to default to a closed state when the vaporizer is not connected with the capsule. 
     
     
         12 . The aerosol-generating system of  claim 11 , wherein the resilient member of the valve is configured to deflect to an open state when the vaporizer penetrates into the reservoir. 
     
     
         13 . The aerosol-generating system of  claim 11 , wherein the valve is a duckbill valve. 
     
     
         14 . The aerosol-generating system of  claim 1 , wherein the capsule defines a passage in fluidic communication with the aerosol passage. 
     
     
         15 . The aerosol-generating system of  claim 14 , wherein the cover defines an end opening in fluidic communication with the aerosol passage. 
     
     
         16 . The aerosol-generating system of  claim 15 , wherein the spring is adjacent to the end opening. 
     
     
         17 . The aerosol-generating system of  claim 14 , wherein the passage is surrounded by the reservoir. 
     
     
         18 . The aerosol-generating system of  claim 1 , wherein the capsule has an elliptical cross section. 
     
     
         19 . The aerosol-generating system of  claim 1 , wherein the capsule has a circular cross section. 
     
     
         20 . The aerosol-generating system of  claim 1 , wherein the capsule includes a complementary member configured to be received by the connecting member of the vaporizer.
