Aerosol generating device

Abstract

An aerosol-generating device includes an accommodating seat and a drive assembly. The accommodating seat defines an accommodating cavity for accommodating an aerosol-forming article. The accommodating cavity has a central axis for the aerosol-forming article to be arranged in the accommodating cavity rotatably around the central axis. The drive assembly includes a drive motor and a transmission unit. The transmission unit is connected to the drive motor and the aerosol-forming article, to transmit power generated by the drive motor to the aerosol-forming article, for the aerosol-forming article to rotate around the central axis.

What is claimed is: 
     
         1 . An aerosol-generating device, comprising:
 an accommodating seat including an accommodating cavity for accommodating an aerosol-forming article, the aerosol-forming article being arranged in the accommodating cavity rotatably around a central axis of the accommodating cavity; and   a drive assembly, comprising:
 a drive motor, and a transmission unit being connected to the drive motor and the aerosol-forming article, the drive motor driving the aerosol-forming article to rotate around the central axis. 
   
     
     
         2 . The aerosol-generating device of  claim 1 , wherein the transmission unit further comprising:
 a first driving member being mounted on a rotating shaft of the drive motor;   a second driving member being mounted on the accommodating seat rotatably around the central axis; and   wherein the first driving member cooperates with the second driving member, to transmit power generated by the drive motor to the second driving member.   
     
     
         3 . The aerosol-generating device of  claim 2 , further comprising:
 a through hole for holding the aerosol-forming article being formed in the second driving member, and the through hole being communicated with the accommodating cavity.   
     
     
         4 . The aerosol-generating device of  claim 3 , wherein the through hole further comprising:
 a first hole segment and a second hole segment;   a plurality of fixing teeth for holding the aerosol-forming article being formed on the first hole segment; and   the second hole segment being sleeved on outer periphery of the accommodating seat.   
     
     
         5 . The aerosol-generating device of  claim 4 , wherein the plurality of fixing teeth is formed on inner wall of the first hole segment. 
     
     
         6 . The aerosol-generating device of  claim 4 , further comprising:
 a groove extending circumferentially around inner wall of the second hole segment; and   a flange matching the groove being formed on outer peripheral wall of the accommodating seat.   
     
     
         7 . The aerosol-generating device of  claim 2 , wherein the first driving member further comprises a first driving gear, the second driving member further comprises a second driving gear, and the first driving gear is meshed with the second driving gear. 
     
     
         8 . The aerosol-generating device of  claim 2 , wherein the first driving member comprises a first driving wheel, and the second driving member comprises a second driving wheel; and
 the transmission unit further comprises a belt or a chain, wherein the first driving wheel drives, through the belt or the chain, the second driving wheel.   
     
     
         9 . The aerosol-generating device of  claim 2 , wherein the first driving member comprises a swing rod, and the second driving member comprises a ratchet sleeve; and
 the transmission unit further comprises a pawl, wherein the swing rod drives, through the pawl, the ratchet sleeve to rotate.   
     
     
         10 . The aerosol-generating device of  claim 1 , wherein the aerosol-generating device further comprises:
 a cavity, wherein the accommodating cavity is formed in the cavity; and   a microwave radiation element, wherein the microwave radiation element is arranged deviating from the central axis and located at the periphery of the accommodating cavity,   wherein the aerosol-forming article is rotating through the drive assembly.
