Abstract
A bubble removal preparation device and method for a gel-state electronic liquid (e-liquid) are provided. The preparation device includes a negative-pressure chamber and a cooling element, where the negative-pressure chamber is provided therein with a porous e-liquid containing chamber. A temperature controller is configured to control the temperature of the cooling element, and a gap between the porous e-liquid containing chamber and the cooling element forms an e-liquid containing cavity.
