Definitions

  • the present invention relates to electronic cigarettes, and particularly to an atomizer and an electronic cigarette using same.
  • electronic cigarettes mainly include disposable electronic cigarettes and refillable electronic cigarette.
  • the disposable electronic cigarettes are not environmental-friendly because they are discarded after used.
  • the refillable electronic cigarettes can be used repeatedly. After tobacco liquid in the refillable electronic cigarettes is used up, the user of the electronic cigarettes can refill the tobacco liquid by themselves. Accordingly, the refillable electronic cigarettes are more environmental-friendly.
  • it is inconvenient to refill the tobacco liquid and the tobacco liquid may pollute clothes of the users during this process.
  • An exemplary atomizer includes a liquid supply component, an atomizing assembly, and a piercing means.
  • the liquid supply component is configured for storing tobacco liquid.
  • the liquid supply component has a sealing means for sealing the tobacco liquid therein.
  • the piercing means for piercing the sealing structure so that the tobacco liquid flows to the atomizing assembly.
  • the atomizing assembly is configured for heating the tobacco liquid to form aerosol.
  • outside refers to a region that is beyond the outermost confines of a physical object.
  • inside indicates that at least a portion of a region is partially contained within a boundary formed by the object.
  • substantially is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder.
  • comprising when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
