A liquid freshening composition is provided. The liquid freshening product includes about 0.5 wt. % to about 15 wt. % isopropyl myristate, by weight of the liquid freshening composition and greater than 40 wt. % of one or more perfume raw materials. The liquid freshening composition has a vapor pressure at 25° C. of about 0.03 Torr to about 1.0 Torr. The liquid freshening composition may be used with air freshening products having a delivery engine such as a wick, breathable membrane, gel, porous and semi-porous substrate, and combinations thereof.

Aspects of the present disclosure include a method of managing scent in an environment, which includes disposing at least one scent diffusion device within an environment, wherein the at least one scent diffusion device comprises a communications facility that enables transmitting signals to and receiving signals from a remote computer, receiving at least one target value of a scent parameter for the environment at the remote computer, and controlling, via the remote computer, diffusion of a liquid from a source of the liquid in fluid communication with the at least one scent diffusion device to achieve the target value of the scent parameter. Controlling a diffusion rate of the liquid includes altering at least one of a voltage and a duty cycle applied to at least one component of the diffusion device.

Methods, systems, and devices are disclosed for implementing switchable dispensing and/or delivery of scented substances. In one aspect, a device includes a cartridge structured to include one or more chambers containing one or more scented substances contained in a corresponding chamber, a housing structured to include a compartment to hold the cartridge, an opening to allow the scented sub stances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to accelerate a scented substance from the corresponding chamber to the opening, and an actuator switch arranged in a corresponding transporting channel and operable to move between an open position and a closed position based on an applied signal to selectively allow passage of the scented substance from the corresponding transporting path.

Methods, devices and systems are described for digitally creating new scents or digitally dispensing gas, vapor, or liquid substances. A device includes a container or replaceable cartridge including one or more chambers containing one or more scented substances; a housing structured to include a compartment to hold the cartridge, an opening to allow the one or more scented or unscented substances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to deliver a scented substance from the corresponding chamber to the opening for delivering a scent from the one or more scented substances; and an actuator switch arranged in a corresponding transporting channel and rapidly operable to move between an open position and closed position based on an applied signal to selectively allow passage of the scented or unscented substance from the corresponding transporting path.

A fragrance dispenser can comprise a housing having a socket portion and defining a receptacle configured to receive a bottle having a fragrance-producing liquid therein and a wick extending therefrom. A heater can be disposed proximate to the receptacle so that, when the bottle is received within the receptacle, the heater is disposed proximate to the wick. A controller can be configured to deliver electrical voltage (e.g., pulse-width-modulated voltage) to the heater. A user input device can be in communication with the controller. The controller receives an input from the user input device that is indicative of a selected heat profile of a plurality of heat profiles, and the controller controls the power output of the heater in accordance with the selected heat profile.

An aerosol-generating system is provided, including a heating element including a plurality of wires that are twisted together; and a capillary body, the capillary body being wound around the heating element. A method of manufacturing an aerosol-generating device is also provided, including providing a capillary body; twisting a plurality of wires together to form a heating element; and winding the capillary body around the heating element. The aerosol-generating system is advantageous in that the manufacturing process can be a fast and robust. The heater can be formed with high precision and consistency. Further, the heater and wick assembly are mechanically robust, allowing manual or automatic handling without affecting its dimensions. This allows for a consistent quality of production.

An electronic scented candle is described that includes a movable flame-shaped component, a shell including an installation chamber, a fragrance container that is removably positioned inside the installation chamber and a scent chamber. An electric fan is positioned within the shell to drive the air into the scent chamber and a scent outlet coupled to the scent chamber to allow the fragrance material to leave the scent chamber and to reach an external environment of the electronic scented candle. The electronic candle also includes a receptacle for connecting a power cord on a bottom surface of the electronic candle. The bottom surface includes a plurality of protruding stands that provide a space to allow the power cord to be connected to the receptacle and be routed below the bottom surface.

Fragrance dispensers with features that are capable of reducing wastage of fragrance, or of conserving fragrance, are disclosed. Such a fragrance dispenser may have a configuration that collects fragrance that is expelled from the fragrance dispenser, but has not vaporized or atomized sufficiently to dissipate into the environment, as well as fragrance that condenses immediately after it has been expelled from the fragrance dispenser. A spill-resistant bottle that may be used with a fragrance dispenser has a shape that orients an opening of the bottle in a somewhat upward orientation to prevent fragrance from spilling out when the bottle is tipped over. Fragrance dispensers with configurations that generate vortices to deliver fragrance into the surrounding environment are also disclosed.

A heater arrangement for a volatile material dispenser includes a cylinder defining an opening and a resistor embedded in the cylinder. The dispenser further includes a housing configured to receive a refill containing a volatile material and a wick. The housing includes a first cavity configured to support the heater arrangement. Further, the dispenser is configured such that, when the refill is received within the housing, the opening receives the wick therein so that a radial gap is formed between the heater arrangement and the wick.

Methods and apparatus for vaporizing liquid into the surrounding environment, including directing liquid from a liquid source to a vaporization port where the vaporization port has lateral dimensions varying from 10 um to 300 um, applying heat to the liquid in the vaporization port with an at least one heating element located in thermal communication to the vaporization port, and releasing vaporized liquid from the vaporization port into the surrounding environment so that fluid is transported through the depth of the structure.
