A scent delivery device and replaceable scent cartridges for use therein

The replaceable scent cartridge of any preceding claim wherein the container further comprises a biasing means contacting the porous material, wherein the biasing means is configured to bias the porous material towards the piezoelectric element.

The replaceable scent cartridge of any preceding claim wherein the container is configured to reversibly couple to a lid portion, wherein the piezoelectric element is arranged at least partially within the lid portion.

The replaceable scent cartridge of any preceding claim wherein the container comprises:

• a reservoir configured to hold scented liquid;
• wherein the porous material is arranged between the reservoir and the piezoelectric element, and wherein the porous material is configured to carry the scented liquid.

The replaceable scent cartridge of any preceding claim wherein the container comprises a cavity, the cavity consisting of the porous material soaked in scented liquid.

The replaceable scent cartridge of any preceding claim wherein the porous material is configured to transport scented media to the piezoelectric element by capillary action.

The replaceable scent cartridge of any preceding claim wherein the piezoelectric element is a microporous piezoelectric element.

The replaceable scent cartridge any preceding claim further comprising a nozzle configured to be in fluid communication with the piezoelectric element, wherein the nozzle is configured to provide an outlet for scented media atomised by the piezoelectric element.

A resealable scent cartridge for a scent delivery device, comprising:

• a container configured to hold a scented media, and
• an impermeable membrane comprising at least one resealable aperture, wherein the impermeable membrane is configured to seal the resealable aperture in a closed configuration, and unseal the resealable aperture in an open configuration.

The scent cartridge of any preceding claim further comprising the scented media, and a scent indication, wherein the scent indication comprises a set of parameters for atomisation of the scented media.

The scent cartridge of any preceding claim wherein the container further comprises a cleaning means, wherein the cleaning means is configured to clean the piezoelectric element when the container is coupled to the piezoelectric element.

The scent cartridge of any preceding claim further comprising a sensor configured to detect an indication of the amount of scented media within the container.
