A portable vaporizing device and/or cartridge comprises a product chamber capable of holding a vaporizable product therein, and a porous valve element configured to be heated to flow the vaporizable product therethrough and generate vapor from the vaporizable product, and optionally including a heat transfer element to heat the vaporizable product as it flows through the product chamber towards the porous valve element.

Dual coil vaporizer inhalation cartridge for high viscosity oil or resin is a specially designed vapor cartridge that includes a second independent heating coil in the oil tank or tank chamber that heats the inhalation oil or resin to reduce its viscosity prior to entering the vaporization chamber where it is vaporized for inhalation. Dual coil vaporizer inhalation cartridge for high viscosity oil or resin uses special electronics to power and control the tank heating coil with the battery and battery switch on a standard battery module for a vaporizer inhalation device, which also powers and controls the vaporization heating coil. The tank heating coil functions to heat and melt the oil/resin or otherwise lower its viscosity to allow the oil/resin to become more thin and runny so that the material may flow more easily through the wick and its capillary action to be successfully transferred to the atomizer heating coil for vaporization.

An electrospray atomizing device that sprays at a constant rate comprises a main unit containing a circuit board, an electrode plate, liquid tanks and syringes. The electrode plate includes the sealed liquid tanks and the syringes, and the circuit board connects electric current to the electrode plate and the syringes. The present invention further includes a power mechanism and a dosing device. The power mechanism drives a screw to ascend or descend, pushing the pistons of the dosing device through a speed changer. The syringes are connected with the liquid tanks. When the pistons are linked by the power mechanism and the speed changer to ascend, the liquid in the liquid tanks is sprayed at a constant rate through the syringes, forming mist which carries negative ions. When the pistons descend, the ambient liquid is sucked into the liquid tanks through the syringes, waiting for a next electrospray.

A humidifier for humidification of air to be delivered to a patient's airways may include a humidification chamber, a reservoir and a water delivery mechanism. The humidification chamber may include a water retention feature such as a wick that encloses part of the flow path, a heating element for heating the humidification chamber, and an air flow baffle configured to promote humidification. The humidifier may be further configured to execute one or more algorithms, for example to determine a condition of the wick or to detect condensation in the flow path. In some forms, the humidifier may also comprise algorithms for controlling one or more components of the humidifier such as to control the build up of foreign matter on the wick.

A composite wick is provided for use in a micro-vaporizer having a fluid reservoir and a heating element. The composite wick comprises a wick body positionable so that its upstream surface is in fluid communication with the fluid reservoir and the downstream surface is disposed in opposition to a surface of the heating element. The wick body comprises at least one base wick structure having a plurality of tortuous passages that collectively provide a capillary effect to draw fluid from the reservoir and transport it toward the downstream surface. The wick body further comprises an active material positioned within the wick body so that vaporizable fluid drawn through the wick body contacts and interacts with the active material. The active material is selected to impart a desired characteristic to the vaporizable fluid.

Apparatus and methods are described for use with a vaporizer that vaporizes at least one active ingredient of a plant material. In response to receiving a first input to the vaporizer, the plant material is heated, in a first heating step. An indication of the temperature of the plant material is detected, and, in response to detecting an indication that the temperature of the plant material is at a first temperature, the first heating step is terminated, by withholding causing further temperature increase of the plant material. The first temperature is less than 95 percent of the vaporization temperature of the active ingredient. Subsequently, a second input is received at the vaporizer. In response thereto, the plant material is heated to the vaporization temperature, in a second heating step. Other applications are also described.

To provide a novel liquid supply method.

Provided is a method for supplying a liquid to an inhaler cartridge including a housing body including an accommodation space capable of accommodating a liquid, a first opening communicating with the accommodation space and opened in a first direction, and a second opening communicating with the accommodation space and opened in a second direction substantially perpendicular to the first direction, and a cap configured to be formed separately from the housing body and close the first opening. The method includes the steps of: closing the first opening with the cap, and after the first opening is closed, supplying the liquid to the accommodation space through the second opening.
