Abstract
A removable cartridge for use with a liquid diffusion device is provided. The removable cartridge includes a cartridge housing defining an internal housing cavity, partially filled with a liquid to be diffused, and a diffusion head positioned within the internal housing cavity with a venturi device for generating diffused liquid from the liquid contained in the internal housing cavity. The diffusion head defines at least a portion of a gas supply conduit that extends from a bottom end of the removable cartridge to the venturi device through the liquid to be diffused to enable the venturi device to be supplied with pressurized gas from an external source via the bottom end of the removable cartridge.
Claims16
A scent dispensing system, comprising:
- a liquid diffusion unit including a pressurized gas source and a control system for controlling discharge of a diffused scent containing liquid from the scent dispensing system;
- and
- a cartridge removably received in the liquid diffusion unit, the cartridge comprising:
- a cartridge receptacle comprising a plurality of pieces fixedly coupled together to define a tamperproof receptacle and having an internal cavity partially filled with a scent containing liquid to be diffused;
- a venturi device within the internal cavity of the cartridge receptacle for generating the diffused scent containing liquid from the scent containing liquid contained in the internal cavity;
- and
- a gas supply conduit that extends from a bottom end of the cartridge toward the venturi device through the scent containing liquid to be diffused to enable the venturi device to be supplied with pressurized gas from the pressurized gas source of the liquid diffusion unit via the bottom end of the cartridge.
A scent dispensing system, comprising:
- a liquid diffusion unit including a pressurized gas source and a control system for controlling discharge of a diffused scent containing liquid from the scent dispensing system;
- and
- a cartridge removably received in the liquid diffusion unit, the cartridge comprising:
- a cartridge receptacle including a lower portion and an upper portion that are fixedly coupled together to prevent non-destructive disassembly of the cartridge, and having an internal cavity partially filled with a scent containing liquid to be diffused;
- a venturi device within the internal cavity of the cartridge receptacle for generating the diffused scent containing liquid from the scent containing liquid contained therein;
- and
- a gas supply conduit that extends from a bottom end of the cartridge toward the venturi device through the scent containing liquid to be diffused to enable the venturi device to be supplied with pressurized gas from the pressurized gas source of the liquid diffusion unit via the bottom end of the cartridge,
- wherein a plurality of chambers are provided downstream of the venturi device through which the diffused scent containing liquid sequentially moves towards an outlet of the cartridge, the plurality of chambers including a primary expansion chamber, a secondary chamber and a tertiary chamber, and
- wherein the primary expansion chamber is located immediately above the venturi device, the secondary chamber is radially adjacent to the primary expansion chamber and surrounds the primary expansion chamber, and the tertiary chamber is provided by a convoluted passageway that extends from the secondary chamber toward the outlet of the cartridge.
