Abstract

A nebulizer utilizing a nozzle assembly includes a main conduit and an air pressure duct. The main conduit is disposed on the nebulizer and has an inner surface and an outer surface. The main conduit has an atomizing opening. The air pressure duct is disposed on one of the inner surface and the outer surface of the main conduit, and has a connecting opening connected to the sensor and a detecting opening that is exposed and adjacent to the atomizing opening. The sensor is disposed inside the nebulizer and determines a pressure change of the atomizing opening by detecting the pressure of the detecting opening. The nebulizer includes an atomizing module and a controlling module electrically connected to the atomizing module and the sensor, and the controlling module determines whether the atomizing module should be turned on based on the pressure change of the atomizing opening detected by the sensor.

Core Innovation

The invention provides a nebulizer apparatus in which an atomizer atomizes a fluid stored in the main body in response to a control input. A sensor reads an air pressure of a sensor opening disposed on a casing of the main body, and a controller receives the air pressure and adjusts the control input of the atomizer based at least in part on an air pressure change.

The nebulizer further includes a nozzle assembly mechanically attachable to the main body, where the nozzle assembly includes a main conduit portion configured to guide atomized fluid to a user piece. The nozzle assembly also includes an air pressure duct portion that fluidly connects the sensor opening on the casing to the user piece via an air pressure detecting aperture or a detecting opening arranged adjacent to the user piece.

The disclosed nozzle assembly includes a duct and a separate ring, where the ring is removable from the main body and carries the air pressure detecting aperture or detecting opening when detached from both the user piece and the main body. The detachable nozzle parts are described as enabling cleaning and replacement of the nozzle portion that includes the duct and ring.

Claims Coverage

The partial content includes two independent claims. Each independent claim shares the same core architecture of pressure sensing at a sensor opening in the main body casing and controlling an atomizer using an air pressure change, while both specify a mechanically attachable nozzle assembly with an air pressure duct that includes a removable ring carrying a detecting aperture/opening.

Across the independent claims, the main inventive coverage is the combination of an air pressure sensor at a sensor opening in the main body casing, controller adjustment of an atomizer control input based on an air pressure change, and a nozzle assembly with an air pressure duct that fluidly links the sensor opening to the user piece, implemented with a removable ring carrying the detecting aperture/opening.
