Definitions

  • the disclosure relates to an electronic cigarette comprising an e-liquid chamber.
  • the conventional electronic cigarettes are typically pre-filled with factory-configured e-liquid and subsequently packaged and transported for retail sales or the e-liquid is temporarily filled by users for use.
  • the conventional electronic cigarettes typically have a single sealing ring within an e-liquid chamber and lacks additional sealing measures between the atomizing core and the air passage.
  • the design results in potential e-liquid leakage during transportation due to road vibrations and external forces. Additionally, prolonged periods of inactivity of electronic cigarettes lead to the infiltration of dust and humid air into the atomizing core and the air passage through pores, resulting in deterioration of the e-liquid, rust formation and dust accumulation. These issues impact the performance of the atomizing core and bring health risks to users.
  • the disclosure provides an electronic cigarette comprising an e-liquid chamber.
  • the electronic cigarette comprises an atomizing body and an atomizing core; the atomizing core is disposed inside the atomizing body to absorb and atomize e-liquid.
  • the atomizing body comprises a first e-liquid chamber, a second e-liquid chamber, and an e-liquid delivery section.
  • the e-liquid delivery section is disposed between the first e-liquid chamber and the second e-liquid chamber, so that the first e-liquid chamber is in fluid communication with the second e-liquid chamber.
  • the atomizing core is disposed within the first e-liquid chamber to absorb and atomize the e-liquid stored in the first e-liquid chamber.
  • the e-liquid delivery section comprises a sealing component movable between a first position and a second position.
  • the first position is where the sealing component seals the e-liquid delivery section and thus isolates the first e-liquid chamber and the second e-liquid chamber.
  • the second position is where the sealing component is disconnected from the e-liquid delivery section, allowing the first e-liquid chamber and the second e-liquid chamber to communicate with each other.
  • the e-liquid is directed from the second e-liquid chamber to the first e-liquid chamber by opening or closing the e-liquid delivery section, thus allowing for e-liquid refilling and enhancing the user experience.
  • connection refers to fluid connectivity, where fluids (including liquids and/or gases) can flow from one component to another.
  • connection between two components can refer to direct connection between two components, for example, at least partially aligned between two holes, or connected through intermediates.

  • the electronic cigarette Before using the electronic cigarette, the e-liquid is stored only in the second e-liquid chamber, preventing contact with the atomizing core during storage and transportation, prolonging the service life of the atomizing core while preventing e-liquid leakage; the electronic cigarette further comprises a push-pull rod 43; when using the electronic cigarette, the push-pull rod 43 is used to manage the opening and closing of the e-liquid delivery section 23.
  • the management transfers the e-liquid from the second e-liquid chamber to the first e-liquid chamber, reducing the risk of e-liquid leakage during transportation and satisfying the user's durability expectations; even during extended non-use, there is no concern about e-liquid contamination, ultimately enhancing the user experience.
