  • Existing electronic cigarettes usually each comprise a vaporizer and a battery rod, and the electronic cigarette vaporizer generally comprise a mouthpiece, a liquid storage chamber, a vaporizing member, etc.
  • the cigarette liquid stored in the liquid storage chamber of existing electronic cigarette vaporizer usually has low viscosity.
  • the waxy solid formed by solidification of tobacco tar has high viscosity and can hardly flow at room temperature, and can hardly be vaporized by existing electronic cigarette vaporizers.
  • An object of the disclosure is to provide an electronic cigarette vaporizer which overcomes the above shortcomings.
  • An electronic cigarette vaporizer comprises an outer tube, a mouthpiece member arranged at one end of the outer tube, a connecting member arranged at the other end of the outer tube, and a vaporizing member arranged inside the outer tube.

  • the connecting end fits tightly between the outer tube and the vapor tube.
  • the air between the outer tube and the vapor tube may be compressed and evacuated through the vent aperture, such that the pressure in the storage chamber may be reduced, preventing the vapor substrate from being squeezed out through the substrate through-hole 303 under the pressure to cause leakage.
  • the integrally-formed two-part tube body is made of a material which readily conducts heat.
  • excessive heat energy may be generated and absorbed and transferred to the vapor substrate by the two-part tube body, such that the tobacco tar having high viscosity, the waxy solid formed by solidification of tobacco tar, or the like, may be preheated to reduce viscosity and improve fluidity. It facilitates the vapor substrate to permeate through the substrate through-hole to the tube-shaped vaporizing core. In this way, more vapor substrate may be feed during vaporization, and more vapor may be produced in unit time, thereby providing good user experience.
