Description

The disclosure relates to the field of electronic cigarette, and more particularly to an electronic atomization device with an external e-liquid tank.
Conventional electronic cigarettes usually include only one e-liquid chamber to provide e-liquid to the heating wire and produce smoke. For some electronic cigarettes, the e-liquid is filled into the e-liquid chamber during production, but this leads to problems such as e-liquid leakage and deterioration during storage and transportation. Although some electronic cigarettes do not contain prefilled e-liquid during production, when in use, the user needs to load the e-liquid into the e-liquid chamber.

Further, as shown in FIG. 12, the tank base 203 comprises an enclosing wall 2031 extending towards the second e-liquid chamber 53. The enclosing wall 2031 is disposed around the sealing cap 2051, and has a guiding function thus preventing the mismatch of the sealing cap 2051 during the resetting process; the mismatch will lead to the mobile plug 205 to be unable to seal the through hole 55 and the e-liquid tank 200 to be unable to be reused.
Understandably, to prevent the enclosing wall 2031 from blocking the communication between the second e-liquid chamber 53 and the through hole 55, a notch 2032 is disposed on the enclosing wall 2031. The e-liquid in the second e-liquid chamber 53 flows along the notch 2032 to the through hole 55, and the e-liquid entering the through hole 55 enters the first e-liquid transportation part 52 along the second e-liquid transportation part 54, thereby achieving the e-liquid injection. The number of notches 2032 is adjusted according to the volume of the e-liquid in the second e-liquid chamber 53 to avoid excessive e-liquid volume and pressure, leading to e-liquid leakage. When the volume of the e-liquid in the second e-liquid chamber 53 is too large, the cross-sectional area and quantity of the notch 2032 can be appropriately reduced. In a preferred embodiment of the disclosure, the notch 2032 comprises two channels opposite to each other.
