Abstract

A vaporizer device includes a cartridge and a vaporizer body. The cartridge includes reservoir configured to hold a vaporizable material. The cartridge further includes a channel extending from the reservoir and having an opening at an end of the channel. The vaporizer body includes a movable block. The vaporizer body further includes a controller configured to actuate the movable block, the actuating of the movable block moving the movable block towards the channel to compress the channel, and the compression of the channel ejects, from the opening, at least a portion of the vaporizable material. The vaporizer body further includes a heating element positioned toward the opening of the channel when the cartridge is coupled with the vaporizer body, the heating element configured to vaporize the portion of the vaporizable material.

Claims (32)

1. A vaporizer device, comprising:

a vaporizer body including

a receptacle disposed at a proximal end of the body, the receptacle configured to receive a cartridge while the cartridge is coupled with the vaporizer body, the cartridge including a reservoir holding a vaporizable material, and the cartridge further including a channel extending from the reservoir and having an opening at an end of the channel,

a movable block,

a controller configured to actuate the movable block, the actuating moving the movable block towards the channel to compress the channel, and the compression of the channel ejecting, from the opening at the end of the channel, at least a portion of the vaporizable material included in the reservoir,

a heating element configured to vaporize the vaporizable material ejected from the opening of the channel, and

a pair of electrodes positioned between the end of the channel and the heating element, wherein the pair of electrodes are configured to detect at least the portion of the vaporizable material being ejected from the opening of the channel, and wherein the heating element is activated to vaporize the vaporizable material in response to the pair of electrodes detecting at least the portion of the vaporizable material being ejected from the opening of the channel.

2. The vaporizer device of claim 1 , wherein the channel is positioned proximate to the movable block when the cartridge is coupled with the vaporizer body.

3. The vaporizer device of claim 1 , wherein the heating element is positioned towards the opening of the channel when the cartridge is coupled with the vaporizer body.

4. The vaporizer device of claim 1 , wherein the cartridge further comprises a flow restrictor positioned at an inlet of the channel, and wherein the flow restrictor is configured to prevent the vaporizable material in the channel from flowing back into the reservoir.

5. The vaporizer device of claim 1 , wherein the vaporizer body further comprises a sensor configured to measure an intensity of an inhalation on a mouthpiece of the cartridge, and wherein the controller is further configured to actuate the movable block based on the intensity of the inhalation.

6. The vaporizer device of claim 1 , wherein the vaporizer body further comprises a piezo stack coupled to the movable block, and wherein the controller actuates the movable block by at least actuating the piezo stack.

7. The vaporizer device of claim 1 , wherein the cartridge further comprises a venting hole configured to reduce a negative pressure in a portion of the reservoir.

8. The vaporizer device of claim 1 , wherein the cartridge further comprises a hydrophobic membrane configured to attract one or more bubble that form within the vaporizable material in the reservoir.

9. The vaporizer device of claim 1 , wherein the vaporizer body further comprises a power source, and wherein the power source includes a battery configured to provide power to the heating element.

10. The vaporizer device of claim 1 , wherein the cartridge further comprises a filter positioned at an inlet of the channel, and wherein the filter is configured to prevent one or more air bubbles from entering the channel.

11. The vaporizer device of claim 1 , wherein the channel is formed from a ceramic, a plastic material, and/or a metal.

12. The vaporizer device of claim 1 , wherein an inner wall of the channel is formed from a hydrophobic material and/or includes a hydrophobic coating.

13. The vaporizer device of claim 1 , wherein the heating element is detachable from the vaporizer body.

14. The vaporizer device of claim 1 , wherein the heating element comprises one or more electrical contact pads.

15. The vaporizer device of claim 1 , wherein one or more surfaces of the heating element are roughened in a microscale and/or a nanoscale.

16. The vaporizer device of claim 1 , wherein the channel is positioned between a non-movable block and the movable block when the cartridge is coupled with the vaporizer body.

17. The vaporizer device of claim 1 , wherein one or more surfaces of the heating element are treated with a hydrophilic treatment and/or a hydrophilic coating.

18. The vaporizer of device of claim 1 , wherein the heating element comprises a thermistor fabricated on a diaphragm, and wherein the diaphragm is bonded to a substrate to form a hermetic chamber.

19. The vaporizer device of claim 18 , wherein the heating element comprises a passivation layer disposed on a surface of the heating element, and wherein the passivation layer configured to isolate the heating element and the thermistor from the vaporizable material.

20. A vaporizer device, comprising:

a vaporizer body including

a receptacle disposed at a proximal end of the body, the receptacle configured to receive a cartridge while the cartridge is coupled with the vaporizer body, the cartridge including a reservoir holding a vaporizable material, and the cartridge further including a channel extending from the reservoir and having an opening at an end of the channel,

a movable block,

a controller configured to actuate the movable block, the actuating moving the movable block towards the channel to compress the channel, and the compression of the channel ejecting, from the opening at the end of the channel, at least a portion of the vaporizable material included in the reservoir, and

a heating element configured to vaporize the vaporizable material ejected from the opening of the channel, wherein the heating element comprises a thermistor fabricated on a diaphragm, and wherein the diaphragm is bonded to a substrate to form a hermetic chamber.

21. The vaporizer device of claim 20 , wherein the heating element comprises a passivation layer disposed on a surface of the heating element, and wherein the passivation layer configured to isolate the heating element and the thermistor from the vaporizable material.
