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.

International Classification:

B01F 3/04
A61L 9/14

Abstract:

An air treatment system 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 may further include a lift mechanism to assist in receiving the cartridge and moving the cartridge from a loading position to an operational position. The appliance may also communicate with a smartphone or other external device to provide additional functionality.

Abstract:

A pump device is provided including: a unitary pump frame; an electromagnet arrangement that includes a winding wrapped around a portion of the unitary pump frame; a diaphragm assembly coupled to the unitary pump frame, which includes a movable diaphragm and a manifold; and a pump arm having a proximal end coupled to the unitary pump frame and a distal end supporting a permanent magnet to interact with the electromagnet arrangement to cause the pump arm to swing back and forth during operation to displace the diaphragm and discharge an air stream from the pump device. Related methods of manufacture are also provided.

Abstract:

An insert of a cartridge for use with a liquid diffusing device is provided. The insert includes a body, an inlet provided in the body to receive diffused liquid generated within the cartridge during operation of the liquid diffusing device, an outlet zone defined at least in part by the body through which to discharge the diffused liquid toward an external environment, and a tortuous passage extending between the inlet and the outlet zone to aid in further reducing an average particle size of the diffused liquid as the diffused liquid moves through the tortuous passage. Removable cartridges for use with a diffusion device are also provided which include such an insert.
