Abstract: The present disclosure is directed to a system that is configured to eject fluid vertically away from a thermal microfluidic die for use with scented oils or other fluids. The die is coupled to a rigid planar support board that separates the die from a reservoir of the fluid. The support board includes an opening that is lined with an inert liner that protects an interior surface of the support board from the fluid. The support board includes contact to an external power supply and contacts to the die on a first surface. The die is coupled to this first surface such that the second surface remains free of electrical connections.

Abstract: One or more embodiments are directed to a microfluidic delivery system that dispenses a fluid in a direction that, at least in part, opposes gravity. In one embodiment, the microfluidic delivery system includes a microfluidic refill cartridge that is configured to be placed in a housing. The microfluidic refill cartridge includes at least one nozzle that faces upward or off to a side. The microfluidic refill cartridge includes a fluid transport member that allows fluid to travel upward from a fluid reservoir in opposition to gravity. A fluid path is located above the fluid transport member placing an end of the fluid transport member in fluid communication with a chamber and a nozzle. In response to the microfluidic delivery system receiving an electrical signal, an ejection element is configured to cause fluid in the chamber to be expelled through the nozzle. In response to the fluid being expelled from the nozzle, fluid may be pulled up through the fluid transport member and through the fluid path to refill the chamber.

Abstract: Embodiments disclosed herein are directed to a microfluidic refill cartridge having a vent hole and nozzles on a same side of the cartridge. In one or more embodiments, the vent hole and nozzles are located on upper surfaces of the cartridge, such as on a lid that is coupled to a reservoir. In particular, the nozzles and the vent hole may be formed on a microfluidic delivery member that is secured to the lid. A single cover may be used to cover the vent hole and the nozzles. In some embodiments, the single cover may be a flexible material and may adhere to the microfluidic delivery member.

Abstract: Embodiments are directed to microfluidic refill cartridges and methods of assembling same. The microfluidic refill cartridges include a microfluidic delivery member that includes a filter for filtering fluid passed therethrough. The filter may be configured to block particles above a threshold size to prevent blockage in the nozzles. For instances, particles having a dimension that is larger than the diameter of the nozzles can block or reduce fluid flow through the nozzle.
