Description

The disclosure relates to the field of electronic cigarette, and more particularly, to an atomizer and an electronic cigarette comprising the same.
An electronic cigarette is an electronic device that simulates tobacco smoking by producing the same taste and vapor. In a conventional electronic cigarette, the e-liquid is in direct contact with the atomizer, which leads to corrosion or oxidation of the heating element. The corrosion or oxidation shortens the lifespan of the heating element and introduces impurities into the e-liquid, impacting the vapor taste and harming the user's health.
To solve the aforesaid problems, the first objective of the disclosure is to provide an atomizer.
The atomizer comprises a cartridge, a base, and an atomizing core; the cartridge comprises a cavity used to store e-liquid; the base is disposed on a bottom part of the cartridge; and the atomizing core comprises at least one e-liquid inlet; the atomizing core is movable from a first position to a second position; when the atomizing core is moved to the first position, the at least one e-liquid inlet is located outside the cartridge; when the atomizing core is moved to the second position, the at least one is located inside the cartridge.
The second objective of the disclosure is to provide an electronic cigarette comprising the atomizer.
The quality of the e-liquid is maintained by separating the e-liquid from the atomizing core when the electronic cigarette is not in use. When in use, the atomizing core is pushed inwards and the e-liquid inlet is located inside the cartridge, so that the e-liquid flows smoothly through the e-liquid inlet and into the atomizing core, which increases the lifespan of the electronic cigarette.

In a conventional electronic cigarette, the e-liquid is in direct contact with an atomizer, which leads to corrosion or oxidation of a heating element. The corrosion or oxidation shortens the lifespan of the heating element and introduces impurities into the e-liquid, impacting the vapor taste and harming the user's health.
To solve the aforesaid problems, the disclosure provides an atomizer and an electronic cigarette comprising the same. The atomizer comprises an atomizing core that is detached from the e-liquid.
