摘要： A cyclone separator useable in a surface cleaning apparatus comprises a cyclone chamber and a dirt collection chamber exterior to, and surrounding at least a portion of the cyclone chamber. The dirt collection chamber is in communication with the cyclone chamber via a dirt outlet. An air flow passage extending to the cyclone air inlet travels generally axially through the dirt collection chamber.

摘要： A particle separator for removing particles from a gaseous stream, the particle separator having a separator body having a centerline axis and a peripheral wall defining a separation chamber, a fluid inlet in fluid communication with the separation chamber, a particle outlet in fluid communication with the separation chamber, a fluid outlet in fluid communication with the separation chamber, and a plurality of angled inlet apertures fluidly coupled between the fluid inlet and the separation chamber. A particulate separation system for removing particles from a gaseous stream, the particulate filtration system having an inlet, an outlet, and a plurality of particle separators located between and in fluid communication with, the inlet and the outlet, wherein each of the plurality of particle separators receives less than about 5 percent by volume of the flow of the gaseous stream entering the inlet.

摘要： A cyclonic separator (10) comprises a separation chamber (14), a feed inlet (16) leading into the separation chamber and an underflow discharge (18) leading from the separation chamber. The cyclonic separator further comprises a vortex finder which has an inlet end positioned in the separation chamber, an outlet end defining an overflow discharge, and a bleed opening (48) defined by the inlet and outlet ends of the vortex finder and through which a portion of an overflow stream can be bled from the vortex finder to remove oversized particles from the overflow stream.

摘要： Monolithic dust separation devices are disclosed to enable separating and collecting dust particles. The devices include a vacuum port and a cyclone chamber that are connected by a tube between the vacuum port and an upper end of the cyclone chamber. On the cyclone chamber there is an input port for connecting to a flexible hose for ingesting the dust particles. The devices also include a dust receptacle having a top upper surface and a port cover on a port formed in the upper surface for emptying the receptacle of collected dust particles and a lower portion of the dust receptacle that is integrally formed into the upper surface of the dust receptacle. The top upper surface slants downward from the cyclone chamber to the port cover.

摘要： A handheld vacuum cleaner includes a main body with a handle extending along a handle axis. The handheld vacuum cleaner also includes a motor assembly positioned within the main body. The handle axis intersects the motor assembly. The handheld vacuum cleaner also includes a dirty air inlet positioned at a front of the handheld vacuum cleaner and extending along an inlet axis. In addition, the handheld vacuum cleaner includes a cyclonic chamber in fluid communication with the dirty air inlet and the motor assembly. The cyclonic chamber defines a separator axis. The inlet axis and the separator axis intersect to form an acute angle extending between the dirty air inlet and the cyclonic chamber. The inlet axis and the handle axis intersect to form an obtuse angle extending between the dirty air inlet and the handle.
