Vaporization element, device and method for vaporizing phyto material. A hollow member defining a fluid pathway is positioned proximate a heating element with a phyto material contact surface. An electrical heater is positioned on the opposite side of the phyto material contact surface. Phyto material or extract deposited on the phyto material contact surface can be vaporized by heat from the electrical heater. The vapor can enter the fluid pathway and pass through the hollow member to an inhalation aperture. The electrical heater may be powered by an electrical power source provided in a support unit. The hollow member can be mounted to a vapor processing device that cools and/or filters the vapor before it reaches the inhalation aperture. The support unit may have securement mechanisms to attach the vapor processing device to the vaporization device.

A heating element assembly for a vaporizing apparatus can include a housing, a heating element disposed within the housing, a magnetic connector, and a spacing member. The housing can comprise an outer wall defining an inner bore and a base portion disposed within the inner bore, the base portion defining an upper well portion and a lower well portion. The upper well portion can receive at least a portion of a therapeutic agent container. The heating element can increase in temperature when a current is applied. The magnetic connector can be disposed at least partially within the housing and coupled to the heating element. The spacing member can be disposed between the heating element and the magnetic connector. The magnetic connector can be configured to couple an electric power source.

A sintered body for use as a liquid reservoir in an electronic cigarette, medication administering devices, in thermally heated evaporators for fragrant substances is provided. The sintered body is made of open-pore sintered glass and has a porosity of greater than 50 vol %. The average pore size is in a range from 1 to 450 μm. The glass of the sintered body has a transition temperature T.sub.g of at least 450° C.

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.

A pump arrangement for powering a pump in providing a controlled volume of water to a drip nozzle in a drip-feed humidifier. The pump arrangement includes: a pump having a solenoid; a processing unit; and a power supply electrically connected to the solenoid via a switch which is controlled by the processing unit. The power supply is structured to supply power to the solenoid via the switch. The processing unit is programmed to modulate the power provided to the solenoid via the switch such that the power is supplied to the solenoid according to a mirror image power profile for each actuation of the solenoid for retracting the armature. The mirror image power profile includes: an initial portion which decreases at a third overall rate, an intermediate portion which decreases at a second overall rate different than the third overall rate, and a final portion which increases at a first overall rate.

To provide a control device for an aerosol inhalator capable of compensating changes in temperature of a heater due to inhalation. A control device for an aerosol inhalator includes a first sensor for obtaining a first value relating to a temperature of a load which atomizes an aerosol source stored in a reservoir or retained by an aerosol base using heat generated by supply of electric power, a second sensor configured to detect an inhalation, and a controller, wherein the controller is configured to determine, based on a second value based on the first value and a threshold, whether the aerosol source in the reservoir or the aerosol base is depleted or insufficient (850A), and correct at least one of the second value and the threshold when detecting the inhalation (840) and, in the determination, compare the second value and the threshold, at least one of the second value and the threshold being corrected (842).

A power supply unit for an aerosol inhaler includes: a power supply able to discharge power to a load for generating an aerosol from an aerosol source; a connector able to be electrically connected to an external power supply; a control device configured to control at least one of charging and discharging of the power supply or configured to be able to convert power which is input from the connector into charging power for the power supply; and a zener diode provided between the connector and the control device so as to be connected in parallel with the control device. A maximum value of zener voltage of the zener diode is lower than a maximum operation guarantee voltage of the control device.

Various systems and methods are provided for creating a wicking structure. In one example, a method for creating a wicking structure can include creating, using a 3D printing technique, a macro wicking element including a lattice structure formed by a grid of a first material, the lattice structure including pores formed between the grid of first material. The method can also include creating, using the 3D printing technique, a first micro wicking element including powder particles distributed within the pores of the lattice structure, and creating, using the 3D printing technique, a second micro wicking element by removing at least a portion of the lattice structure.
