  • Publication number: 20240081418
    Abstract: A liquid injection device includes: an accommodating cavity for detachable mounting of an electronic vaporization device; a liquid storage tank; a liquid supply mechanism; and a control assembly. The control assembly is connected to the liquid supply mechanism and detects whether the electronic vaporization device is mounted in the accommodating cavity. The liquid supply mechanism is in communication with the liquid storage tank to: be connected to the electronic vaporization device and supply liquid to the electronic vaporization device when the electronic vaporization device is mounted in the accommodating cavity, and be disconnected from the electronic vaporization device and stop supplying liquid to the electronic vaporization device when the electronic vaporization device is removed from the accommodating cavity.
