Abstract

An e-cigarette cartridge includes a housing with an air inlet and an air outlet; and the housing is provided with a liquid storage cavity, a porous body, a vaporization cavity, a heating element, a support frame, and a vapor output channel, where the vaporization cavity is in airflow communication with the air inlet; the support frame is constructed to provide the porous body with support and holding; and the vapor output channel includes a first channel part and a second channel part that are formed on the support frame and extend in a width direction of the housing. One end of the first channel part is in communication with the vaporization cavity and the other end is in communication with the air outlet; one end of the second channel part is in airflow communication with the vaporization cavity and the other end is in airflow communication with the air outlet.

First claim

1 : An e-cigarette cartridge, comprising a housing with a near end and a far end facing away from each other in a longitudinal direction, wherein the far end is provided with an air inlet and the near end is provided with an air outlet; and the housing is internally provided with:
a liquid storage cavity, configured to store a liquid substrate; a porous body, being in fluid communication with the liquid storage cavity to suck the liquid substrate and having a vaporization surface; a vaporization cavity, at least partially defined by the vaporization surface, wherein the vaporization cavity is in airflow communication with the air inlet; a heating element, formed on the vaporization surface and configured to heat at least a part of the liquid substrate in the porous body to generate an aerosol; a support frame, constructed to provide the porous body with support and holding; and a vapor output channel, comprising a first channel part and a second channel part that are formed on the support frame and extend in a direction of a width of the housing, wherein one end of the first channel part is in airflow communication with the vaporization cavity and the other end is in airflow communication with the air outlet; one end of the second channel part is in airflow communication with the vaporization cavity and the other end is in airflow communication with the air outlet; and further the aerosol in the vaporization cavity is divided into two flows by the first channel part and the second channel part in use, and then the two flows are merged and outputted to the air outlet.

2 : The e-cigarette cartridge according to claim 1 , wherein the support frame comprises a first part and a second part facing away from each other in the longitudinal direction, wherein the liquid storage cavity is defined between the first part and the housing, and the second part provides the porous body with support and holding; and
the vapor output channel comprises a hollow cavity formed between the first part and the second part.

3 : The e-cigarette cartridge according to claim 2 , wherein the hollow cavity is internally provided with a separating part extending between the first part and the second part, and the separating part separates the hollow cavity to form the first channel part and the second channel part.

4 : The e-cigarette cartridge according to claim 2 , wherein the second part has an airflow guiding surface opposite to the first part, and the airflow guiding surface is constructed into a sloping arrangement.

5 : The e-cigarette cartridge according to claim 1 , wherein a first liquid inlet hole and a second liquid inlet hole are formed on the support frame, wherein the first liquid inlet hole provides a first liquid path between the liquid storage cavity and the porous body, and the second liquid inlet hole provides a second liquid path between the liquid storage cavity and the porous body; and a pore size of the first liquid inlet hole is greater than a pore size of the second liquid inlet hole, or the pore size of the second liquid inlet hole is greater than the pore size of the first liquid inlet hole.

6 : The e-cigarette cartridge according to claim 5 , wherein the second liquid inlet hole penetrates through the separating part.

7 : The e-cigarette cartridge according to claim 1 , wherein the housing comprises a cylindrical body and an end cap, wherein the end cap comprises a support arm for supporting the support frame, wherein the support arm is provided with a first liquid storage groove in communication with the vaporization cavity, to adsorb by a capillary action and hold an aerosol condensate in the vaporization cavity.

8 : The e-cigarette cartridge according to claim 7 , wherein the support frame is further provided with a second liquid storage groove, wherein the second liquid storage groove is in airflow communication with the vapor output channel, to further adsorb by the capillary action and hold the aerosol condensate in the vapor output channel.

9 : The e-cigarette cartridge according to claim 8 , wherein the second liquid storage groove is in fluid communication with the first liquid storage groove, to transport the aerosol condensate in the second liquid storage groove to the first liquid storage groove.

10 : An e-cigarette, comprising the e-cigarette cartridge according to claim 1 and a power supply device for supplying power to the e-cigarette cartridge.
