Microfluidic delivery device for dispensing and redirecting a fluid composition in the air

A microfluidic delivery device comprising:

• a housing electrically connectable with a power source, wherein the housing comprises an interior and an exterior;
• a cartridge releasably connectable with the housing, wherein the cartridge comprises a reservoir for containing a fluid composition and a microfluidic die in fluid communication with the reservoir, wherein the reservoir comprises a first end portion, a second end portion opposing the first end portion, and a sidewall that joins the first and second end portions, wherein the microfluidic die is configured to dispense substantially all of the fluid composition in an upward direction relative to horizontal, wherein horizontal is normal to the direction of gravitational force;
• a fan;
• first and second air flow channels disposed in the interior of the housing, each of the first and second air flow channels extending from the fan to an air outlet, and
• an air flow cover selectively positionable between a first position and at least a second position, wherein in the first position the air flow cover blocks air flow through the first air flow channel, and wherein in the second position the air flow cover blocks air flow through the second air flow channel.
