Abstract

Various embodiments of a system for generating an inhalable aerosol are described. In some embodiments, the system includes a vaporizer device with a heating system configured to heat a vaporizable material insert. The heating system can include a heating element positioned adjacent a vaporizable material compartment configured to receive the vaporizable material insert. The heating system can include a compression plate configured to press the vaporizable material insert against the heating element. The heating system can include an airflow pathway extending along the vaporizable material compartment. Various embodiments of vaporizer material inserts that can be included and used with the system are also described. Related systems, methods, and articles of manufacture are also described.

First claim

What is claimed is:

1 . A heating system of a vaporizer device for generating an inhalable aerosol, the heating system comprising:
a heating element positioned along a vaporizable material insert receptacle configured to receive a vaporizable material insert, the heating element configured to heat the vaporizable material insert for generating the inhalable aerosol; a compression element for pressing the vaporizable material insert against the heating element, the compression element comprises:
a first compression plate and a second compression plate positioned along opposing sides of the vaporizable material insert receptacle, wherein the first compression plate and the second compression plate are configured to move towards each other to press the vaporizable material insert against the heating element;
a plurality of first protrusions extending from the first compression plate and into the vaporizable material insert receptacle, the plurality of first protrusions configured to apply pressure against the vaporizable material insert;
a plurality of second protrusions extending from the second compression plate and into the vaporizable material insert receptacle, the plurality of second protrusions configured to apply pressure against the vaporizable material insert; and
an airflow pathway extending along the vaporizable material insert receptacle for allowing the inhalable aerosol to flow through an outlet of the vaporizer device; wherein at least one first protrusion and at least one second protrusion are positioned opposite each other.

2 . The heating system of claim 1 , wherein the vaporizable material insert receptacle comprises two channels extending along opposing sides of the heating element, each of the two channels being configured to receive a vaporizable material insert.

3 . The heating system of claim 2 , wherein the heating element includes a first side configured to contact and heat a first vaporizable material insert, the heating element including a second side configured to contact and heat a second vaporizable material insert.

4 . The heating system of claim 1 , wherein a part of the airflow pathway extends between at least two first protrusions, at least two second protrusions, or a combination thereof.

5 . The heating system of claim 1 , further comprising a spring that applies a spring force against the compression element to assist with pressing the vaporizable material insert against the heating element.

6 . The heating system of claim 1 , further comprising an insulation layer positioned adjacent a first side of the heating element, the first side of the heating element being opposed to a second side of the heating element defining a part of the vaporizable material insert receptacle.

7 . The heating system of claim 1 , wherein the heating element includes a helical configuration that is configured to receive a vaporizable material insert having a cylindrical shape.

8 . The heating system of claim 1 , further comprising a compression adjusting feature that allows an amount of compression force provided by the compression element to be adjusted.

9 . The heating system of claim 1 , wherein the heating element comprises a flexible material configured to conform to the vaporizable material insert when the vaporizable material insert is pressed against the heating element.

10 . The heating system of claim 1 , wherein the vaporizable material insert includes an insert housing that contains a vaporizable material.

11 . The heating system of claim 1 ,
wherein at least one first protrusion, at least one second protrusion, or a combination thereof extend substantially along a length of the vaporizable material insert receptacle in a longitudinal direction.

12 . A vaporizer system for generating an inhalable aerosol, the vaporizer system comprising:
a vaporizable material insert including a vaporizable material; and a vaporizer device comprising:
a heating system comprising:
a heating element positioned along a vaporizable material insert receptacle configured to receive the vaporizable material insert, the heating element configured to heat the vaporizable material insert for generating the inhalable aerosol;
a compression element for pressing the vaporizable material insert against the heating element, the compression element comprises:
a first compression plate and a second compression plate positioned along opposing sides of the vaporizable material insert receptacle, wherein the first compression plate and the second compression plate are configured to move towards each other to press the vaporizable material insert against the heating element;
a plurality of first protrusions extending from the first compression plate and into the vaporizable material insert receptacle, the plurality of first protrusions configured to apply pressure against the vaporizable material insert;
a plurality of second protrusions extending from the second compression plate and into the vaporizable material insert receptacle, the plurality of second protrusions configured to apply pressure against the vaporizable material insert; and

an airflow pathway extending along the vaporizable material insert receptacle for allowing the inhalable aerosol to flow through an outlet of the vaporizer device;
wherein at least one first protrusion and at least one second protrusion are positioned opposite each other.

13 . A method for generating an inhalable aerosol for inhalation by a user, the method comprising:
receiving a vaporizable material insert including a vaporizable material into a vaporizable material insert receptacle of a vaporizer device; compressing the vaporizable material insert against a heating element positioned along the vaporizable material insert receptacle with a compression element, wherein the compression element comprises:
a first compression plate and a second compression plate positioned along opposing sides of the vaporizable material insert receptacle, wherein the first compression plate and the second compression plate are configured to move towards each other to press the vaporizable material insert against the heating element;
a plurality of first protrusions extending from the first compression plate and into the vaporizable material insert receptacle, the plurality of first protrusions configured to apply pressure against the vaporizable material insert; and
a plurality of second protrusions extending from the second compression plate and into the vaporizable material insert receptacle, the plurality of second protrusions configured to apply pressure against the vaporizable material insert;
wherein at least one first protrusion and at least one second protrusion are positioned opposite each other; and
activating the heating element to heat the vaporizable material of the vaporizable material insert to form the inhalable aerosol.

14 . The method of claim 13 , further comprising:
adjusting a compression force provided by the compression element.

15 . The method of claim 14 , wherein the vaporizer device comprises a spring that applies the compression force against the compression element.

16 . The method claim 14 , wherein the vaporizer device comprises a compression adjusting feature that adjusts the compression force.
