1. A method for injecting an E-liquid into a cartridge of an electronic cigarette, comprising:
a) selecting an E-liquid guiding body, and assembling the E-liquid guiding body with the cartridge;
wherein the cartridge includes an E-liquid storage tank configured for receiving an injection of the E-liquid, the E-liquid guiding body is configured to be in a fluidic communication with the E-liquid that is injected into the E-liquid storage tank,
b) injecting the E-liquid into the E-liquid storage tank of the cartridge; and
c) sealing the cartridge in a sealing bag after the injection of the E-liquid is completed,
wherein, a pressure inside the E-liquid storage tank of the cartridge after the cartridge is injected with the E-liquid is P1, a pressure of an external environment external to the E-liquid storage tank of the cartridge after the cartridge is injected with the E-liquid is P2, P2>P1, that is, a negative pressure or a reverse pressure differential is formed inside the E-liquid storage tank of the cartridge relative to the pressure of the external environment external to the E-liquid storage tank of the cartridge, and
wherein an anti-E-liquid-leakage coefficient ΔP1 of the E-liquid guiding body and an anti-air-resistance coefficient ΔP2 of the E-liquid guiding body satisfy the following condition: (P2−P1)−(ΔP2−ΔP1)≥ΔP1, such that the E-liquid guiding body absorbs, to a maximum degree, the E-liquid from the E-liquid storage tank after the cartridge has been injected with the E-liquid, while avoiding a leakage of the E-liquid in a non-operating state and maintaining a smooth E-liquid supply in an operating state.
