Abstract
A personal vaporizer is configured to be usable both for non-liquid vaporizing media and for liquid vaporizing media. In some embodiments an electrically conductive check valve blocks vaporizing media from leaking out of air intake apertures during periods of nonuse, and delivers electric power to a heating element during use. In some embodiments, no wick structures extend into a fluid chamber, but a wick extends from a wick holder downstream of the fluid chamber to a vaporizing chamber.
Claims20
A personal vaporizer, comprising:
- a tank module comprising a fluid chamber and a vapor passage extending through the fluid chamber, the fluid chamber configured to contain a vaporizing solution;
- an atomizer module comprising a bowl having an upper edge and an air aperture, a heating element arranged in or adjacent the bowl, the bowl configured to accept vaporizing solution received from the fluid chamber;
- a check valve comprising an insulator housing, a conductive shell inside the insulator housing, and a sealing mechanism inside the conductive shell, the conductive shell having an air inlet and an air outlet, an intake air flow path defined through the conductive shell from the air inlet to the air outlet, the sealing mechanism providing a seal inside the conductive shell, the seal interposed in the intake air flow path, the check valve arranged so that that the air outlet communicates with the bowl air aperture and the conductive shell is electrically connected to the heating element;
- and
- a battery assembly, the heating element connectable to the battery assembly through the check valve so that actuation of the battery delivers electrical energy to the heating element, causing the heating element to heat and vaporize the vaporizing solution;
- wherein the bowl has a first wire hole and a second wire hole extending through a bottom wall of the bowl and a channel extending transversely from the second wire hole.

An atomizer for a personal vaporizer, comprising:
- a housing having a distal end and a proximal end, the housing comprising an electrically conductive material, the distal end configured to be attachable to a first pole of a battery so that the distal end electrically communicates with the battery;
- an atomizer bowl arranged within the housing, the atomizer bowl comprising a side wall and a bottom wall, the atomizer bowl configured to receive vaporizing media;
- a heating element disposed at least partially within the atomizer bowl, the heating element having a first wire end portion and a second wire end portion, the heating element configured to produce heat when electric energy is applied across the first wire end portion and the second wire end portion;
- a check valve having a valve body, a proximal outlet, a distal inlet, and a sealing structure interposed in an air flow path between the distal inlet and the proximal outlet, the valve body extending from a distal end to a proximal end and defining an electrically conductive flow path from the distal end to the proximal end, the sealing structure configured to accommodate air flow therethrough along the air flow path in a distal-to-proximal direction, but to resist air flow therethrough in a proximal-to-distal direction;
- wherein the first wire end portion is in electrical communication with the proximal end of the valve body and the second wire end portion is in electrical communication with the housing.
