Abstract: A system is provided for treating a space at least partially enclosed by a wall with an aerosolized compound. The system includes a discharge unit, a liquid diffusion appliance, and a conduit extending therebetween. The discharge unit is mounted to a first side of the wall and includes an aerosol outlet in fluid communication with the space to be treated. The liquid diffusion appliance is mounted to a second side of the wall and includes a control system for operating the liquid diffusion appliance to generate and discharge an aerosolized compound from an appliance outlet. The conduit couples the appliance outlet with the discharge unit and defines a passageway through the wall through which the aerosolized compound travels to be discharged into the space to be treated.

Abstract: An air treatment appliance is provided which includes an appliance housing and a removable cartridge received therein. The removable 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 removable cartridge to generate the aerosolized compound from the liquid compound contained in the removable cartridge, and a controller is provided for controlling the pump to supply the air to the removable cartridge to generate and discharge the aerosolized compound from the appliance. In some instances, the appliance housing includes a base, a cover, and an inner sub-housing coupled to the base to collectively define a passageway with an air outlet positioned to discharge a flow of air across a path of the aerosolized compound discharged from the cartridge outlet during operation.

Abstract: An air treatment appliance is provided which includes an appliance housing and a removable cartridge received therein. The removable cartridge includes a receptacle containing a liquid compound to be aerosolized within an interior thereof and a cap assembly coupled to the receptacle. The cap assembly includes a cap, a venturi insert, and a base attached together without welds or separate fasteners to define an air inlet chamber on one side of the venturi insert, a venturi outlet passage on the other side of the venturi insert in fluid communication with the interior of the receptacle, and an aerosol outlet chamber partitioned from the interior of the receptacle by the base and in fluid communication with an outlet of the cap through which aerosolized compound generated by the venturi insert is discharged during operation.

Abstract: A removable replaceable cartridge for use with a liquid diffusing device. The cartridge includes a venturi, a conduit extending to the venturi, a mixing area and an outlet path for atomizing and dispersing a liquid within the cartridge. A diffusion device including a removable replaceable cartridge received within a housing. The housing includes a source of compressed gas which is directed into the cartridge. A venturi head with a unitary body for use with a diffusion device.

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: A system is provided for treating a trash chute with an aerosolized compound. The system includes an aerosol discharge unit mounted to a door frame of a fire door arrangement of the trash chute with an aerosol outlet thereof in fluid communication with the trash passageway; a liquid diffusion appliance mounted remotely from the trash chute and the fire door arrangement, the liquid diffusion appliance including a compound in liquid form to be aerosolized and including a control system for operating the liquid diffusion appliance to generate the aerosolized compound from the liquid compound and to discharge the aerosolized compound from an appliance outlet of the liquid diffusion appliance; and a conduit coupling the appliance outlet of the liquid diffusion appliance with the aerosol outlet of the discharge unit, the conduit defining an aerosol passageway through which the aerosolized compound travels to be discharged into the trash chute.

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.

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.

Abstract: A removable replaceable cartridge for use with a liquid diffusing device. The cartridge includes a venturi, a conduit extending to the venturi, a mixing area and an outlet path for atomizing and dispersing a liquid within the cartridge. A diffusion device including a removable replaceable cartridge received within a housing. The housing includes a source of compressed gas which is directed into the cartridge. A venturi head with a unitary body for use with a diffusion device.

Abstract: A method of controlling operation of a diffusion appliance to treat the atmosphere within an enclosed space. The method may include programming the operation of the appliance according to a control scheme specifying a flow rate of liquid to a diffusion means and a periodic operation of the diffusion means. Control schemes may be associated with different volumes of spaces to be treated by the appliance, the rate of decay of the liquid within the space to be treated and the level of concentration of the liquid desired within the space.

Abstract: A method and system of controlling operation of a diffusion appliance to treat the atmosphere within an enclosed space. The appliance may be programmed to operate according to a control scheme specifying a flow rate of liquid to a diffusion means and a periodic operation of the diffusion means. Control schemes may be associated with different volumes of spaces to be treated by the appliance. Anti-fatigue schemes may provide variation of the flow rate or periodic operation of the appliance. Initiation controls schemes may be used to start treatment of the space before the appliance is programmed to operate according to one of the control schemes.

Abstract: The advertising panel is to display an advertising message and to diffuse a scent which is associated with the contents of the visually-displayed message. The inventive panel includes a parallelepiped volume containing: an assembly which is used to display an advertising message that is disposed opposite a display window, and at least one scent diffuser which is connected to a scent-diffusing element which is in turn installed opposite an opening in the panel, such as to diffuse a scented flow to the exterior. The diffusing element is connected to the head of the scent diffuser, thereby ensuring that a carrier gas is mixed with the scented fluid contained in the receptacle. The scented flow obtained at the outlet of the head is pulsed towards the diffusing element and, subsequently, to the exterior of the panel.
