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.
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:
A method of maintaining a desired level of an aerosolized compound within a space to be treated with the compound, the method including providing a diffusion device with the compound in liquid form and a control system for operating the device. The control system includes a sensor in fluid communication with the air within the space to be treated configured to sense the concentration of the compound aerosolized within the space. The diffusion device is operated to diffuse the compound into the space. The concentration of the compound within the space to be treated is sensed with the sensor and operation of the diffusion device is altered based on the concentration of the compound sensed to achieve a desired concentration of compound within the space. The sensing and operation altering steps are repeated periodically to maintain the desired concentration of the compound within the space.
