first embodiment
[0036]In the first embodiment, the mouthpiece assembly includes a filter 21 and a sealing ring 22. The sealing ring 22 is disposed between the filter 21 and the ventilation tube 23 acting as a seal to prevent the e-liquid to be absorbed into the mouthpiece portion. The central of the sealing ring 22 has a through air vent. The filter 21 communicates with the ventilation tube 23 by the air vent.
[0037]The e-liquid accommodation assembly includes a columnar liquid-storage cotton 24. The liquid-storage cotton 24 is disposed at one side of the sealing ring 22 in the inhalation rod 27. The liquid-storage cotton 24 has a through central hole. In the central hole installs a liquid-guiding cotton 25 for guiding e-liquid. The ventilation tube 23 passes through the liquid-guiding cotton 25. Between the ventilation tube 23 and the liquid-guiding cotton 25 disposes a fixing tube 26. The atomization assembly partly stretches into the ventilation tube 23.
[0038]The atomization assembly includes a b...
second embodiment
[0049]In the second embodiment, the mouthpiece assembly includes a filter 31 and a sealing ring 32. The sealing ring 32 is disposed between the filter 31 and the ventilation tube 23 acting as a seal to prevent the e-liquid to be absorbed into the mouthpiece portion.
[0050]The difference between the second embodiment and the first embodiment is: Referring to FIG. 9 and FIG. 10, one end of the filter 31 facing the sealing ring 32 has a convex stage 31a, and a central of the sealing ring 32 is recessed to form a grove 32a and a through air vent. The convex stage 31a is positioned in the groove 32a. The filter 31 is fixed on the inner wall of the cavity of the inhalation rod 27 by the sealing ring 32, and communicates with the ventilation tube 23 by the air vent. When installing, firstly make the filter 31 matching fixed with the sealing ring 32 by the convex stage 31a, then fix with a first mounting part on the inner wall of the cavity of the inhalation rod 27 by the sealing ring 32 or ...
third embodiment
[0056]In the third embodiment, by increasing friction on the outer surface of the filter to fix with the inner wall of the inhalation rod 47, it is not required to use glue or other adhesive containing harmful ingredients, avoiding the users inhaling in glue or harmful ingredients of adhesive when smoking the electronic cigarette, and being good for long-term use of the electronic cigarette.
