Aerosol generation device with ejection mechanism using leverage

Abstract

An aerosol generation device with an ejection mechanism using leverage includes: an aerosol generation chamber configured to receive and heat a substrate to generate aerosol; a cover which can be in a closed position covering the aerosol generation chamber, and in an open position exposing the aerosol generation chamber; and an ejection mechanism having a lever and being at least partially engaged with the cover so as to eject at least a portion of the substrate out of the aerosol generation chamber when the cover is in the open position.

1 . An aerosol generation device, comprising:
 an aerosol generation chamber configured to receive and heat a substrate to generate aerosol,   a cover which can be in a closed position covering the aerosol generation chamber, and in an open position exposing the aerosol generation chamber, and   an ejection mechanism having a lever and being at least partially engaged with the cover so as to eject at least a portion of the substrate out of the aerosol generation chamber when the cover is in the open position;   wherein the ejection mechanism is configured to be in an ejected state in which the substrate protrudes from the aerosol generation chamber, and in a non-ejected state in which the substrate is fully contained by the aerosol generation chamber; and   the ejection mechanism translates from the non-ejected state to the ejected state when the cover is moved from the closed position to the open position, thereby ejecting the substrate by rotating the lever.   
     
     
         2 . The aerosol generation device according to  claim 1 , wherein when the cover is moved from the open position to the closed position, the lever rotates back to an original position so as to enter the non-ejected state, in which the substrate is fully inserted into the aerosol generation chamber. 
     
     
         3 . The aerosol generation device according to  claim 1 , wherein the cover is configured to be in an intermediate position between the open position and the closed position, the lever does not rotate when the cover is moved from the closed position to the intermediate position, and the lever ejects the substrate by rotating when the cover is moved from the intermediate position to the open position. 
     
     
         4 . The aerosol generation device according to  claim 1 , wherein the lever at least partially defines a bottom surface of the aerosol generation chamber. 
     
     
         5 . The aerosol generation device according to  claim 1 , wherein the ejection mechanism has a sliding track, and a sliding block slidingly engaged with the cover, and the lever is arranged to slide in the sliding track so as to trigger rotation of the lever. 
     
     
         6 . The aerosol generation device according to  claim 5 , wherein a fixing mechanism is configured to cause the lever to mechanically engage with the sliding block so that the lever rotates when the sliding block slides and vice versa. 
     
     
         7 . The aerosol generation device according to  claim 5 , wherein a protrusion of the cover is slidingly engaged with an end of the sliding block so that when the cover is moved from the closed position to the open position, or from the open position to the closed position, the lever is pressed down or lifted up, respectively. 
     
     
         8 . The aerosol generation device according to  claim 5 , wherein at least parts of the ejection mechanism comprises metal material. 
     
     
         9 . The aerosol generation device according to  claim 1 , wherein the aerosol generation device has an elongated shape, and the cover is arranged to slide in a longitudinal direction of the aerosol generation device. 
     
     
         10 . The aerosol generation device according to  claim 7 , wherein the protrusion of the cover is made of metal material. 
     
     
         11 . The aerosol generation device according to  claim 7 , wherein the end of the sliding block is made of metal material.
