Presented are a method and apparatus for evacuation. An exemplary fluid evacuation system includes a surgical apparatus having a fluid conduit therethrough. The system further includes a vacuum tube fluidly coupled with the fluid conduit, and an electrostatic precipitator fluidly coupled with the fluid conduit. Additionally, the system includes a vacuum source fluidly coupled with the vacuum tube, wherein the vacuum source is operable to create a flow of fluid through the fluid conduit, the vacuum tube and the electrostatic precipitator.

A self-cleaning ion generator device includes a housing having a bottom portion and a top portion selectively secured to each other, the top portion contains a base portion extending to an outer edge and having an internal side and an external side, a first pair of opposed sidewalls and a second pair of opposed sidewalls extend from the outer edge of the base portion forming a cavity therein. Ion terminals extend from the housing, and a cleaning apparatus for cleaning the two ion terminals.

Apparatuses for converting a non-ionized gas stream into an ionized gas stream are disclosed. Disclosed apparatus include an ionizing wire electrode at least partially disposed within and stationary relative to a channel. A frame has plural support elements for supporting the ionizing wire. The frame is configured to make full rotations around the channel in a first rotation direction while applying tension to the ionizing wire. The support elements are configured to physically remove material from the ionizing wire while the support elements are moved along the wire by the frame rotation.

The present invention provides methods and systems for a self-cleaning ion generator that includes a self-cleaning ion generator device that includes a bottom portion, a top portion, at least one electrode extending from the top portion, and a cleaning apparatus for cleaning the at least one electrode.

A cleaning device for cleaning an air-ionizing part of an electrode. The device comprises a cleaning member arranged to be in physical contact with the air-ionizing part of the electrode, the air-ionizing part of electrode and the cleaning member being arranged to slide relative to each other. The cleaning device further comprises an actuator arranged to activate the relative motion between the air-ionizing part of the electrode and the cleaning member. There is also provided an ionization electrode comprising the air-ionizing part and the cleaning device, as well as a ultrafine particle sensor, an air ionizer or an electrostatic air cleaner comprising such an electrode.

An easy-to-clean separable purification core for an air purifier includes an inner cavity lining body, a collector module and a repeller module that are detachably inserted one in the other. The collector module includes a first collector cell and a second collector cell that are nested from top to bottom and are detachable with respect to each other, the two collector cells match each other in shape and dimension size and are respectively provided with collector pieces parallel to each other, and the spacing between two adjacent collector pieces in each collector cell is four times of an original spacing. In an assembly state of the purification core, the collector module, the repeller module, and the inner cavity lining body are nested one in another to form an integral component.
