An air scenting system for a vehicle is provided which includes an appliance and a replaceable cartridge installable therein. The replaceable cartridge contains a liquid compound to be aerosolized and has a cartridge outlet through which the aerosolized compound is discharged during operation. A pump is provided to supply air to the replaceable cartridge to generate the aerosolized compound from the liquid compound contained in the replaceable cartridge, and a controller is provided for controlling the pump to supply the air to the replaceable cartridge to generate and discharge the aerosolized compound from the appliance. The appliance is particularly adapted for dispensing scent into the interior space of a vehicle, and includes a form factor particularly well suited for positioning the appliance in a cup holder. Additionally, the appliance is designed for use in vehicles when a driver is present and readily adjustable by the driver to provide a uniform scent experience.

Air scenting appliance for a vehicle

A method of maintaining a desired level of a dispersed liquid within an occupiable semi-enclosed space is provided. The method includes: providing a liquid diffusion appliance including a liquid to be dispersed; operating the liquid diffusion appliance to disperse the liquid into the occupiable semi-enclosed space throughout a treatment period in which the occupiable space is subjected to entry and exit of occupants to and from the occupiable semi-enclosed space; sensing the concentration of one or more chemical components of the dispersed liquid within the occupiable semi-enclosed space; and modifying the operation of the liquid diffusion appliance based on the concentration of the one or more chemical components of the dispersed liquid within the occupiable semi-enclosed space to achieve a desired concentration.

A removable replaceable cartridge for use with a liquid diffusing device. The cartridge includes a venturi, a conduit extending to the venturi, a mixing area and an outlet path for atomizing and dispersing a liquid within the cartridge. A diffusion device including a removable replaceable cartridge received within a housing. The housing includes a source of compressed gas which is directed into the cartridge. A venturi head with a unitary body for use with a diffusion device.

Diffusion device with replaceable cartridge

A method of maintaining a desired level of an aerosolized compound within a space to be treated with the compound, the method including providing a diffusion device with the compound in liquid form and a control system for operating the device. The control system includes a sensor in fluid communication with the air within the space to be treated configured to sense the concentration of the compound aerosolized within the space. The diffusion device is operated to diffuse the compound into the space. The concentration of the compound within the space to be treated is sensed with the sensor and operation of the diffusion device is altered based on the concentration of the compound sensed to achieve a desired concentration of compound within the space. The sensing and operation altering steps are repeated periodically to maintain the desired concentration of the compound within the space.

A method of controlling operation of a diffusion appliance to treat the atmosphere within an enclosed space. The method may include programming the operation of the appliance according to a control scheme specifying a flow rate of liquid to a diffusion means and a periodic operation of the diffusion means. Control schemes may be associated with different volumes of spaces to be treated by the appliance, the rate of decay of the liquid within the space to be treated and the level of concentration of the liquid desired within the space.

A method and system of controlling operation of a diffusion appliance to treat the atmosphere within an enclosed space. The appliance may be programmed to operate according to a control scheme specifying a flow rate of liquid to a diffusion means and a periodic operation of the diffusion means. Control schemes may be associated with different volumes of spaces to be treated by the appliance. Anti-fatigue schemes may provide variation of the flow rate or periodic operation of the appliance. Initiation controls schemes may be used to start treatment of the space before the appliance is programmed to operate according to one of the control schemes.
