Abstract

This application provides an e-cigarette vaporizer and an e-cigarette. The e-cigarette vaporizer includes an outer housing including an open end and an end cap arranged at the open end, where a liquid storage cavity and a sealing base configured to seal the liquid storage cavity are provided in the outer housing; a sealing ring is arranged between the end cap and the outer housing; a vaporization cavity is provided between the sealing ring and the sealing base, and the liquid substrate is vaporized in the vaporization cavity to generate aerosol released to the vaporization cavity; and a plurality of liquid storage grooves configured to adsorb and hold aerosol condensate are provided in the vaporization cavity. The e-cigarette vaporizer uses the liquid storage groove for absorbing the condensate through the capillary action, and prevents the condensate from being taken out along with inhaling airflow during inhaling.

First claim

What is claimed is:

1. An electronic cigarette (e-cigarette) vaporizer, comprising an outer housing comprising an open end and an end cap arranged at the open end, and a near end disposed spaced away from the open end for inhaling of an aerosol from the vaporizer, wherein:
a liquid storage cavity configured to store a liquid substrate and a sealing base configured to seal the liquid storage cavity are provided in the outer housing;
a sealing ring is arranged between the end cap and the outer housing;
a vaporization cavity is provided between the sealing ring and the sealing base, a heater is disposed in the vaporization cavity, and the liquid substrate from the liquid storage cavity is vaporized due to heating of the heater in the vaporization cavity to generate the aerosol released to the vaporization cavity; and the aerosol is inhaled at the near end by moving from the vaporization cavity toward the near end, and condensates are condensed from the moving aerosol when the aerosol moves away from heating of the heater toward the near end, a plurality of liquid storage grooves configured to absorb and hold the condensate through capillary action are provided on a surface partially defining and surrounding the vaporization cavity.

2. The e-cigarette vaporizer according to claim 1 , wherein a width of each of the plurality of liquid storage grooves is between 0.05 mm and 0.2 mm.

3. The e-cigarette vaporizer according to claim 1 , wherein non-airflow communication is maintained between the plurality of liquid storage grooves and the liquid storage cavity.

4. The e-cigarette vaporizer according to claim 1 , wherein a vapor-gas output channel is further arranged in the outer housing, and the plurality of liquid storage grooves are in airflow communication with the vapor-gas output channel.

5. The e-cigarette vaporizer according to claim 1 , wherein the plurality of liquid storage grooves comprise a first liquid storage groove provided on a surface of the end cap facing an inner wall of the outer housing.

6. The e-cigarette vaporizer according to claim 5 , wherein a heating element configured to vaporize the liquid substrate to generate the aerosol and release the aerosol into the vaporization cavity, and a porous body configured to transmit the liquid substrate of the liquid storage cavity to the heating element are arranged in the vaporization cavity;
a support frame configured to accommodate and hold the porous body is further arranged in the vaporization cavity; and
a support arm configured to provide support to the support frame is arranged at the end cap, and the first liquid storage groove at least partially extends on a surface of the support arm.

7. The e-cigarette vaporizer according to claim 5 , wherein a heating element configured to vaporize the liquid substrate to generate the aerosol and release the aerosol into the vaporization cavity, and a porous body configured to transmit the liquid substrate of the liquid storage cavity to the heating element are arranged in the vaporization cavity;
a support frame configured to accommodate and maintain the porous body is further arranged in the vaporization cavity; and the plurality of liquid storage grooves comprise a second liquid storage groove formed on a surface of the support frame facing an inner wall of the outer housing.

8. The e-cigarette vaporizer according to claim 7 , wherein the second liquid storage groove is constructed to be provided obliquely in a direction close to the sealing base.

9. The e-cigarette vaporizer according to claim 7 , wherein a vapor-gas output channel is further arranged in the outer housing, and the vapor-gas output channel is at least partially located on the surface of the support frame facing the inner wall of the outer housing; and the second liquid storage groove is constructed to be provided at both sides of the vapor-gas output channel in a width direction of the outer housing.

10. The e-cigarette vaporizer according to claim 7 , wherein the second liquid storage groove comprises a first portion extending in a circumferential direction around the support frame and a second portion in communication with the first portion in a longitudinal direction of the support frame.

11. The e-cigarette vaporizer according to claim 10 , wherein the second portions are separated from each other in the longitudinal direction of the support frame.

12. The e-cigarette vaporizer according to claim 1 , wherein the plurality of the liquid storage grooves are discretely provided without intersecting or connecting with each other.

13. An e-cigarette, comprising a vaporizing device for vaporizing a liquid substrate to generate aerosol, and a power supply device for supplying power to the vaporizing device, wherein the vaporizing device comprises the e-cigarette vaporizer according to claim 1 .

14. The e-cigarette vaporizer according to claim 2 , wherein the plurality of liquid storage grooves comprise a first liquid storage groove provided on a surface of the end cap facing an inner wall of the outer housing.

15. The e-cigarette vaporizer according to claim 14 , wherein a heating element configured to vaporize the liquid substrate to generate the aerosol and release the aerosol into the vaporization cavity, and a porous body configured to transmit the liquid substrate of the liquid storage cavity to the heating element are arranged in the vaporization cavity;
