An Aerosolization Module for an Aerosol Generating System Having an Optimized Configuration

Abstract

An aerosolization module for an aerosol generating device includes a reservoir configured to contain a vaporizable material, a heater including a wick which is configured to imbibe liquid by capillarity, and a liquid path for providing liquid from the reservoir to the heater that includes at least one liquid channel that fluidically connects the reservoir to the wick, the liquid channel including a porous pad in contact with the wick. The porous pad improves the reliability in the supply of vaporizable material to the heater.

1 . An aerosolization module for an aerosol generating device comprising:
 a reservoir configured to contain a vaporizable material arranged near a mouthpiece end of the aerosolization module,   a heater configured for liquid aerosolization; the heater comprising a wick which is configured to imbibe liquid by capillarity, the heater being arranged between the reservoir and a power supply connecting end,   a liquid path for providing liquid from the reservoir to the heater,   
       the liquid path comprising at least one liquid channel fluidically connecting the reservoir to the wick, the at least one liquid channel comprising a porous pad in contact with the wick, wherein the porous pad is arranged between the heater and the power supply connecting end, such that the liquid flows substantially in a direction from the power supply connecting end toward the mouthpiece end over a portion of the liquid path. 
     
     
         2 . The aerosolization module according to  claim 1 , wherein the porous pad is made of cotton. 
     
     
         3 . The aerosolization module according to  claim 1 , wherein the at least one liquid channel extends from the reservoir to a chamber located between the heater and the power supply connecting end, said chamber containing the porous pad. 
     
     
         4 . The aerosolization module according to  claim 1 , wherein the reservoir is formed as a single part having at least one external wall, and the at least one liquid channel is arranged along said at least one external wall of the reservoir. 
     
     
         5 . The aerosolization module according to  claim 1 , wherein further comprising a heater holder, the porous pad being interposed between a side portion of the heater holder and a lateral end portion of the heater. 
     
     
         6 . The aerosolization module according to  claim 5 , wherein the heater and/or the heater holder comprises embedded contacts for electrical connection. 
     
     
         7 . The aerosolization module according to  claim 1 , wherein the at least one liquid channel comprises two liquid channels and the aerosolization module further comprises a second porous pads, each of said porous pads being in contact with a respective extremity of the wick of the heater. 
     
     
         8 . The aerosolization module according to  claim 7 , wherein the reservoir comprises a central tube, the heater being placed at a bottom of said central tube. 
     
     
         9 . The aerosolization module according to  claim 8 , wherein the reservoir comprises a first volume and a second volume having a symmetrical arrangement around the central tube, each of the first volume and the second volume being connected to a distinct one of the two liquid channels. 
     
     
         10 . The aerosolization module according to  claim 8 , wherein the heater has an elongated shape and extends substantially orthogonally to the central tube. 
     
     
         11 . The aerosolization module according to  claim 8 , wherein further comprising a heater cover which comprises a hole sealingly fastened to the central tube. 
     
     
         12 . The aerosolization module according to  claim 11 , wherein further comprising a spacer interposed between the heater and the heater cover. 
     
     
         13 . The aerosolization module according to  claim 11 , wherein each of the at least one liquid channel is formed between external walls of a part forming the reservoir and the heater cover. 
     
     
         14 . The aerosolization module according to  claim 11 , wherein a silicone seal is interposed between the hole of the heater cover and the central tube. 
     
     
         15 . The aerosolization module according to  claim 11 , wherein further comprising a silicone part interposed between the heater cover and the heater.
