Abstract
The liquid cartridge includes a storage portion which is configured to store an aerosol-generating substrate in a liquid state and includes an air hole through which air enters, a wick which is configured to absorb the stored aerosol-generating substrate, and a vaporizing portion which is configured to vaporize the aerosol-generating substrate absorbed through the wick to generate an aerosol.
Claims10
A liquid cartridge comprising:
- a storage portion having an accommodating space configured to store an aerosol-generating substrate in a liquid state,
- a wick having two ends and configured to absorb the aerosol-generating substrate that is stored in the accommodating space at the two ends, wherein one or more portions of the wick, excluding the two ends of the wick, are surrounded by a wick housing;
- an air hole configured to introduce air into the accommodating space storing the aerosol-generating substrate in the liquid state and disperse positions where bubbles are generated in the accommodating space to other positions instead of near the two ends of the wick;
- and
- a vaporizing portion configured to generate an aerosol by vaporizing the aerosol-generating substrate absorbed in the wick,
- wherein the air hole is disposed at a connection portion between the wick housing and the storage portion to introduce air inside the wick housing into the accommodating space to generate bubbles near the air hole and disperse positions where bubbles are generated, and
- wherein in a state in which the user's mouth is upward, the air hole is disposed at a lower end of the storage portion and above of the wick.

A liquid cartridge comprising:
- a storage portion having an accommodating space configured to store an aerosol-generating substrate in a liquid state;
- a wick having two ends and configured to absorb the aerosol-generating substrate that is stored in the accommodating space at the two ends, wherein one or more portions of the wick, excluding the two ends of the wick, is surrounded by a wick housing;
- a semipermeable material that prevents the stored aerosol-generating substrate from leaking out of the accommodating space and allows air to be introduced into the accommodating space storing the aerosol-generating substrate in the liquid state;
- a vaporizing portion configured to generate an aerosol by vaporizing the aerosol-generating substrate absorbed in the wick;
- wherein the semipermeable material is disposed at a connection portion between the wick housing and the storage portion,
- wherein the semipermeable material between the storage portion and the wick housing is configured to disperse positions where bubbles are generated in the accommodating space to other positions instead of near the two ends of the wick, and
- wherein air inside the wick housing is introduced into the accommodating space portion storing the aerosol-generating substrate in the liquid state via the semipermeable material between the storage portion and the wick housing.
