Cartridges for vaporizer devices
Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a primary reservoir, a secondary reservoir in fluid communication with the primary reservoir, and a vaporization chamber in communication with the secondary reservoir in which the vaporization chamber includes a first wicking element. The primary reservoir is configured to store a majority fraction of vaporizable material when in a first pressure state and configured to expel the vaporizable material in response to an increase in headspace when in a second pressure state. The secondary reservoir is formed of absorbent material configured to receive a first volume of the vaporizable material from the primary reservoir in the first pressure state and to receive a second volume of the vaporizable material from the primary reservoir in the second pressure state in which the second volume is greater than the first volume. Vaporizer devices are also provided.
1 . A cartridge for a vaporizer device, the cartridge comprising:
a primary reservoir being configured to hold a majority fraction of vaporizable material, the primary reservoir having an internal pressure;
a secondary reservoir being formed of an absorbent material, the absorbent material configured to receive an overflow volume of the vaporizable material that is expelled from the primary reservoir in response to a pressure differential that is created between ambient pressure outside of the primary reservoir and the internal pressure of the primary reservoir; and
a first wicking element extending between the primary and secondary reservoirs, the first wicking element configured to draw the vaporizable material from the primary reservoir into the secondary reservoir.
2 . The cartridge of claim 1 , further comprising a vaporization chamber in communication with the secondary reservoir.
3 . The cartridge of claim 2 , wherein the vaporization chamber comprises a second wicking element configured to draw the vaporizable material from the secondary reservoir to the vaporization chamber for vaporization by a heating element.
4 . The cartridge of claim 3 , wherein the second wicking element is configured to draw the overflow volume of the vaporizable material from the secondary reservoir to the vaporization chamber.
5 . The cartridge of claim 4 , wherein the vaporization chamber includes a third wicking element configured to draw the vaporizable material from the secondary reservoir to the vaporization chamber for vaporization by the heating element.
6 . The cartridge of claim 1 , wherein the pressure differential is associated with a negative pressure event.
7 . The cartridge of claim 1 , wherein the internal pressure of the primary reservoir is less than or equal to the ambient pressure prior to the pressure differential being created.
8 . The cartridge of claim 1 , wherein the ambient pressure is less than the internal pressure of the primary reservoir when the pressure differential is created.
9 . The cartridge of claim 1 , wherein the first wicking element is configured to withdraw at least a portion of the overflow volume of the vaporizable material from the secondary reservoir back to the primary reservoir in response to a decrease of the pressure differential.
10 . A vaporizer device, comprising:
a vaporizer body; and
a cartridge that is selectively coupled to and removable from the vaporizer body, the cartridge including:
a primary reservoir being configured to hold a majority fraction of vaporizable material, the primary reservoir having an internal pressure;
a secondary reservoir being formed of an absorbent material, the absorbent material configured to receive an overflow volume of the vaporizable material that is expelled from the primary reservoir in response to a pressure differential that is created between ambient pressure outside of the primary reservoir and the internal pressure of the primary reservoir;
a first wicking element extending between the primary and secondary reservoirs, the first wicking element configured to draw the vaporizable material from the primary reservoir into the secondary reservoir.
11 . The device of claim 10 , wherein the vaporizer body includes a power source.
12 . The device of claim 10 , further comprising a mouthpiece coupled to the cartridge.
13 . The device of claim 10 , further comprising a vaporization chamber in communication with the secondary reservoir.
14 . The device of claim 13 , wherein the vaporization chamber comprises a second wicking element configured to draw the vaporizable material from the secondary reservoir to the vaporization chamber for vaporization by a heating element.
15 . The device of claim 14 , wherein the second wicking element is configured to draw the overflow volume of the vaporizable material from the secondary reservoir to the vaporization chamber.
16 . The device of claim 15 , wherein the vaporization chamber includes a third wicking element configured to draw the vaporizable material from the secondary reservoir to the vaporization chamber for vaporization by the heating element.
17 . The device of claim 10 , wherein the pressure differential is associated with a negative pressure event.
18 . The device of claim 10 , wherein the internal pressure of the primary reservoir is less than or equal to the ambient pressure prior to the pressure differential being created.
19 . The device of claim 10 , wherein the ambient pressure is less than the internal pressure of the primary reservoir when the pressure differential is created.
20 . The device of claim 10 , wherein the first wicking element is configured to withdraw at least a portion of the overflow volume of the vaporizable material from the secondary reservoir back to the primary reservoir in response to a decrease of the pressure differential.
