## Abstract

A therapeutic vaporizer is disclosed having two or more housing portions configured to form an inner cavity. The housing portions are movable between an open and closed position, such that at least a portion of the inner cavity is enclosed when the housing portions are in the closed position. The vaporizer includes at least one accessory-receiving element configured to receive at least one accessory within the inner cavity when the housing portions are in the closed position.

## Claims

### Claim 1

A therapeutic vaporizer, comprising:
a housing comprising:
a first housing portion,
a second housing portion,
a hinge connecting the first housing portion to the second housing portion such that the first housing portion is movable relative to the second housing portion between an open position and a closed position, and
a mezzanine connected to the second housing portion and configured to divide an interior of the housing, in the closed position, into a first cavity section between the first housing portion and the mezzanine and a second cavity section between the mezzanine and the second housing portion, wherein the first cavity section is accessible when the housing is in the open position of the housing;
a gas flow device contained within the second cavity of the housing;
a heater contained within the second cavity of the housing, the heater comprising a chamber and a heating element configured to selectively heat a gas flowed from the gas flow device and through the chamber;
a valve positioned between the gas flow device and the heater and configured to provide selective temperature isolation between the gas flow device and the heater;
a bowl receptacle formed in the mezzanine and configured to removably receive and support a bowl, the bowl comprising:
an inner bowl cavity comprising a first therapeutic material support configured for supporting a vaporizable material;
an inlet providing fluid communication between the inner bowl cavity and the chamber, and
an outlet providing fluid communication from the inner bowl cavity;
an intermediary conduit positioned within the second cavity of the housing and between the heater and the bowl, the heater in fluid communication with the bowl via the intermediary conduit;
a diverter positioned within the second cavity of the housing configured to selectively:
in a first configuration, allow flow of the gas through the bowl, and
in a second configuration, allow flow of the gas around the bowl;
a first temperature sensor configured to detect a first temperature proximate to or within a portion of the heater;
a second temperature sensor configured to detect a second temperature proximate to or within a fluid pathway formed downstream of the heater;
a temperature controller electrically connected to the first and the second temperature sensors and the heating element for controlling the temperature of a gas flowed through the bowl cavity;
a gas analysis system positioned within the bowl or downstream of the bowl and configured to:
determine an amount of CO in the gas, and
adjust a temperature of the heating element based on the determined amount of CO in the gas; and
a second therapeutic material support positioned in the first housing portion so as to be proximate to the outlet of the bowl when the housing is in the closed position, the second therapeutic material support formed as a tray, a basin, a receptacle or another container configured to support an aromatic material selected from an oil, a liquid, a gel, a solid or a semi-solid material, wherein the first housing portion further comprises a housing channel configured to fluidly engage with the outlet of the bowl in the closed position of the housing and disengage from the outlet of the bowl in the open position of the housing.

### Claim 2 (depends on 1)

The therapeutic vaporizer of claim 1, wherein the temperature controller is configured to control the operation of the heating element in response to an output received from at least one of the first and second temperature sensors.

### Claim 3 (depends on 2)

The therapeutic vaporizer of claim 2, wherein the temperature controller is configured to control the operation of the heating element in response to an output received from both the first and the second temperature sensors.

### Claim 4 (depends on 1)

The therapeutic vaporizer of claim 1, further comprising at least one accessory-receiving element positioned at least partially within the portion of the first cavity of the housing, the accessory-receiving element configured to receive and at least partially conceal at least one accessory within the inner cavity when the first and second housing portions are in the closed position.

### Claim 5 (depends on 4)

The therapeutic vaporizer of claim 4, wherein the accessory-receiving element comprises a groove configured to receive an inhalation tube, wherein the inhalation tube is connectable to the outlet of the bowl when the housing is in the open position.

### Claim 6 (depends on 1)

The therapeutic vaporizer of claim 1, wherein the heating element comprises a halogen bulb.

### Claim 7 (depends on 1)

The therapeutic vaporizer of claim 1, further comprising at least one of an inhalation tube and an inhalation bag.

### Claim 8 (depends on 1)

The therapeutic vaporizer of claim 1, wherein the valve is a butterfly valve.

### Claim 9 (depends on 1)

The therapeutic vaporizer of claim 1, wherein the gas analysis system is configured such that, when the determined amount of CO in the gas exceeds a threshold, the temperature of the heating element is reduced or the heating element is deactivated.

### Claim 10 (depends on 1)

The therapeutic vaporizer of claim 1, wherein the gas analysis system is configured to determine a vapor density of the gas and provide a closed loop automatic control system configured to dynamically optimize vapor production with reduced combustion constitutes.

### Claim 11 (depends on 1)

The therapeutic vaporizer of claim 1, wherein the gas analysis system is configured to analyze the gas using at least one of spectroscopy, thin layer chromatography, and mass spectrometry.

### Claim 12 (depends on 1)

The therapeutic vaporizer of claim 1, further comprising a sensor for detecting whether the housing is in the open position or the closed position, and wherein the gas flow device is controlled based on an output of the sensor.

### Claim 13 (depends on 12)

The therapeutic vaporizer of claim 12, wherein the heater is controlled based on an output of the sensor.

### Claim 14 (depends on 1)

The therapeutic vaporizer of claim 1, wherein:
in the open position of the housing, gas passing through the first therapeutic material support of the bowl exits the outlet of the bowl without passing through the second therapeutic material support; and
in the closed positon of the housing, the gas passing through the first therapeutic material support of the bowl exits the outlet of the bowl and is directed by the housing channel through the second therapeutic material support and exits through apertures formed through the first housing portion.
