- the upper 331 and lower 332 ends are open, and closed by pads 35 of cellulose, cotton or the like. similar fibrous material. These pads 35 are permeable to vapor so as to allow the latter to pass.
- the use of buffers 35 has the effect of creating additional pressure drops when the steam passes through room 33, in effect modifying the feeling of pulling by the user.
- the reserve 34 is placed in the passage 333 of the part 33.
- Figure 8 is a diagram of a third embodiment of part 33.
- the passage 333 is in the form of a helix (or a screw thread) opening at each of the upper 331 and lower 332 ends of the tube forming the part 33.
- the vapor thus circulates in the part 33 following a helical direction creating pressure drop.
- Reserve 34 is configured to match the helical shape of passage 333.
- Figure 9 is a diagram of a fourth embodiment of part 33.
- the passage 333 is in the form of a baffle
- the reserve 34 is configured to adapt to the baffle shape of the passage 333.
- FIG 10 is a diagram of a fifth embodiment of the part 33.
- the part 33 is in the form of a tube formed of at least two sections T1, T2, preferably three sections T1, T2, T3. At least two of these sections have different cross sections. It is this difference in section that induces the pressure drops.
- the end sections T1 and T3 are flared or funnel-shaped open at each of their end, and the central section T2 is tubular.
- the end sections T1, T3 have their large opening which coincides with the ends of the central tubular section T2.
- the part 33 could constitute sections T1 + T2 or T2 + T3 or T1 + T3.
- Figure 11 is a diagram of a sixth embodiment of part 33.
- This embodiment is a combination of the first and the second embodiment.

- the part 33 (whether or not integrating the reserve 34) is mounted in a removable manner in the mouthpiece 32.
- a part 33 is advantageously used in the form of a tube whose shape and dimensions of the outer wall correspond to those of the central channel 321. The insertion of the part 33 into the channel 321 can be done from the inhalation end 322 or the other opposite end of said channel.
- the part 33 integrates the reserve 34 and the aromas and / or the nicotine that it contains are exhausted, the user only has to replace said part with another part incorporating a reserve 34 filled with aromas and / or or nicotine.
- This solution is particularly economical in that the user does not have to change the entire mouthpiece 32 but can, on the contrary, keep it.
- the insertion of the part 33 into the central channel 321 can also be easily implemented in an industrial manufacturing process.
- the part 33 (whether or not integrating the reserve 34) is mounted in a non-removable manner in the mouthpiece 32 and for example fixed by gluing or welding in the central channel 321.
- the part 33 When the part 33 integrates the reserve 34 and the aromas and / or the nicotine it contains are exhausted, the user must in this case replace the assembly of the nozzle 32 with another nozzle incorporating a reserve 34 filled with 'aromas and / or nicotine. This may be more advantageous for the user as they simply need to remove the used tip and replace it with a new tip.
- the reserve 34 is directly integrated into the central channel 321 of the mouthpiece 32, the part 33 is not used. In this case, it is the reserve 34 which alone contributes to creating the pressure drop when it is crossed by the flow of steam.
- the whole of the nozzle 32 that should be replaced when the aromas and / or the nicotine are exhausted.
- the advantages of this type of tip are similar to those described in the previous paragraph.
