A compact modular multifunctional inhalation device including a housing having an inlet port and an outlet port; a removable cartridge module adapted to seat within the housing, the cartridge including: a tray within the cartridge for holding a solid inhalant, a heating element mounted within the cartridge above and through the tray for heating the inhalant; and a removable modular electronic circuit adapted to seat within the housing to provide electrical current to the heating element. The heating element is a coil mounted within a chamber in thermal proximity to the solid inhalant. A quartz rod is mounted within the coil. A plunger is mounted within the cartridge to translate therein and compact the solid inhalant. In an alternative embodiment, dual channels and outlet ports are mounted in communication with an inlet port. In another embodiment, the cartridge is a split chamber cartridge with a split plunger mounted therein. Yet another embodiment features a measurement glass cover gauge mounted on the cartridge.

Provided herein are systems and methods to generate an inhalable vapor in an electronic vaporization device. The vaporization device may generate a vapor with one or more defined characteristics. In some cases, the vapor may have a predetermined aerosol number density and/or a predetermined average aerosol diameter. The vaporization device may generate a vapor from a vaporizable material. In some cases, the vaporizable material may be a liquid material housed in a cartridge. The vaporization device may comprise a rechargeable power storage device.

The invention relates to a nebulization device (1) for medical mixture, of the type comprising: a containing ampoule (2) for medical mixture, comprising an upper component (2a) and a lower component (2b) connected to each other; at least one emission opening (11) of said nebulized medical mixture from the ampoule (2), and at least one entry window (19) for the intake of air within said ampoule (2); as well as at least one atomizer (14) for the intake of pressurized gas, within the lower component (2b) of the ampoule (2), the atomizer (14) being surmounted by the upper component (2a). Advantageously, at least one, preferably two selection side windows (24) are provided on the upper component (2a), the opening of said selection side windows (24) being shielded by shielding means (16), moved by a command shaft (17).

A cartridge is inserted onto a nebulizer that aerosolizes (or vaporizes) liquid drawn from a cartridge reservoir via a flow path into a nebulization chamber. In such a nebulizer, an inlet port is coupled to an external air supply and leads through a Venturi nozzle into the chamber to direct an air stream across an opening of the flow path, while a discharge port leads from the chamber to a user mask, mouthpiece or cannula, where the aerosol or vapor mixture can be inhaled. A filtered outlet port isolates exhaled material from the external environment. Multiple discrete heating elements may be placed around the flow path to preheat the liquid. If the liquid is sufficiently volatile, heating may vaporize the material which can condense back into an aerosol after mixing with the air stream. A set of check valves direct one-way flow and prevent leakage or spillage of material from the cartridge or nebulizer. The cartridge and nebulizer can receive coded information for third-party activation by an authorized establishment.

A nebulizer device aerosolizes (or vaporizes) liquid drawn from a liquid reservoir via a fluid flow path into a nebulization chamber. An inlet port is coupled to an external air supply and leads through a check valve and Venturi nozzle (e.g. a duckbill valve) into the chamber to direct an air stream across an opening of the fluid flow path. A discharge port leads from the chamber to a user mask, mouthpiece or canula, where the aerosol or vapor mixture can be inhaled. A filtered outlet port isolates exhaled material from the external environment. Multiple discrete heating elements may be placed around the fluid flow path to preheat the liquid.

A set of check valves direct one-way fluid flow and prevent leakage or spillage of material from the device.

An electronic cigarette includes a battery assembly and an atomizer assembly within a housing with the battery assembly electrically connected to the atomizer assembly. The housing has one or more air inlets. A liquid storage component is in contact with a porous component of the atomizer assembly, with the porous component having a run-through hole. A heating wire is in an air flow path through the run-through hole.

An electronic cigarette includes a battery assembly, an atomizer assembly and a cigarette bottle assembly. An external thread electrode is located in one end of battery assembly. An internal thread electrode is located in one end of atomizer assembly. The battery assembly and the atomizer assembly are connected by the screwthread electrode. The cigarette bottle assembly is inserted into the other end of the atomizer assembly and both form a cigarette type or cigar type body.

Provided are an atomizing head (1), an atomizer (100) and an electronic cigarette. The atomizing head (1) comprises a shell (12) provided with a liquid inlet (121) and an inner cavity (17), and an atomizing head base (81) provided with an air inlet channel (151), where the liquid inlet (121) and the air inlet channel (151) are both in communication with the inner cavity (17); a bottom end of the shell (12) is fixedly connected to the atomizing head base (81); an elastic element (16) encloses an air outlet end of the air inlet channel (151); the elastic element (16) has a first state and a second state; in the first state, the air inlet channel (151) is in communication with the inner cavity (17); and in the second state, the air inlet channel (151) and the inner cavity (17) are blocked up against each other.

An aerosol-generating system may include a liquid storage portion, a vaporizer, and a pump. The liquid storage portion may be configured to store a liquid aerosol-forming substrate. The vaporizer may be configured to volatilize the liquid aerosol-forming substrate. The pump may be configured to pump air into the liquid storage portion so as to push out a volume of the liquid aerosol-forming substrate from the liquid storage portion and to supply the volume of the liquid aerosol-forming substrate to the vaporizer. A method for generating an aerosol may be performed with the system.

A method and a circuit system for driving a nebulizer are provided. When the nebulizer receives acoustic waves, a control circuit extracts audio signals from the acoustic waves. Afterwards, the control circuit determines if the audio signals are within a predetermined frequency range, and can determine whether or not to drive a circuit to produce an aerosol based on the audio signals. Further, a volume of the acoustic waves can also be used to determine whether or not to produce the aerosol, and also determine an output rate of the aerosol. The circuit system of the nebulizer includes an audio receiver for receiving the acoustic waves, an aerosol generator for producing the aerosol, and the control circuit used to control a driving circuit of the aerosol generator to drive a vibrational element to produce the aerosol through vibration in response to the audio signals and the volume.
