Abstract: A breast shield for a breast pump comprises a first (inner) cavity for placing over the nipple and having a first pressure control port for controlling milk expression. A second (outer) cavity is radially outward of the first cavity and is coupled to a second pressure control port for providing a sealing or positioning and then holding function. Thus, a positioning/holding function and a milk expression function may be optimized independently.

Abstract: A teat for use with a fluid container comprises a deformable mouthpiece for an infant to suck on during a fluid intake action and an inner core disposed within the mouthpiece. An exterior surface of the inner core is spaced from an interior surface of the mouthpiece at the position of a fluid pocket guiding face of the exterior surface of the inner core so that a fluid duct between the mouthpiece and the inner core is defined which allows the infant to perform a peristaltic fluid intake action. At least one of the interior surface of the mouthpiece and the exterior surface of the inner core has at least one protrusion that is designed to form a fluid barrier between the mouthpiece and the inner core at a position for delimiting the fluid duct at the sides thereof.

Abstract: A baby bottle device (100) is provided which comprises a container (110) with a container volume (115), a teat (120) with a teat volume (125) and a valve unit (200). The teat comprises a first valve (112) for inletting air into the inside volume of the bottle (100). The inside volume of the bottle corresponds to the volume of the container (110) and the teat volume (125). The valve unit (200) with a second valve (210 230) is arranged outside the teat volume (125). The threshold of the vent unit is lower than the threshold of the first vent (112) in the teat.

Abstract: A wet cleaning apparatus includes a cleaner head having a dirt inlet. A motor and fan deliver suction to the dirt inlet. Further, the wet cleaning apparatus includes a separator unit for separating water from a flow of air generated by the suction. The separated water is collected in a container having a top and a bottom, and a side portion extending there between. The separated air is passed out of the container towards the motor and fan via an air passage. The air passage is spatially separated from the bottom of the container. The water collected in the container sloshes against the side portion of the container when a user is pushing the cleaner head and the container forward. A water directing member sealingly adjoins the side portion, and protrudes into the container backwards from the side portion, thereby to inhibit the water sloshing against the side portion.

Abstract: Provided is a wet cleaning apparatus (10), such as a wet vacuum cleaner. The wet cleaning apparatus comprises a dirt inlet (11), and a motor (14) and fan (16) for delivering suction to the dirt inlet. A separator unit (18) separates water from a flow of air generated by the suction. The apparatus further includes a container (19) for collecting the separated water. The container has a top (19A) and a bottom (19B). An air passage (22) is provided in the container for passing the air separated from the water towards the motor and fan. The air passage is spatially separated from the bottom of the container. An internal wall (19E) extends from the top towards the bottom of the container. A space (25) is thus defined between the container and the internal wall. Water collected at the bottom of container is receivable in the space when the container is orientated, e.g. tilted, such that the collected water moves from the bottom towards the top of the container.

Abstract: A vacuum cleaner is described. The vacuum cleaner has a dirt inlet and a motor and fan for delivering suction to the dirt inlet. A cyclone unit separates particles from a suction flow. The cyclone unit has a vortex finder extending along a cyclone axis of rotation and an annular chamber formed around outside of the vortex finder. Air is delivered to the cyclone unit in a forward direction (i.e. in a direction from the dirt inlet to the cyclone unit). The cyclone axis of rotation is substantially parallel to the forward direction. An outlet from the vortex finder is at a backward end thereof such that the outlet is in an opposite direction to a forward component. A space beyond the vortex finder is a part of a dirt collection area, thus enabling a more effective collection of hairs and other debris.

Abstract: A cyclone separation device includes a cyclone chamber for separating dirt from incoming air, a dirt collecting chamber arranged adjacent to the cyclone chamber for collecting dirt particles separated from air, and a dirt duct between the cyclone chamber and the dirt collecting chamber for allowing dirt particles to exit the cyclone chamber into the dirt collecting chamber. To reduce the generation of noise-generating air vortices, the dirt duct has an edge protruding into a direction at an angle to the dirt duct at an exit ridge of the cyclone chamber that is first encountered by the air rotating in the cyclone chamber. Preferably, the edge is formed by a tangential extension of a wall of the cyclone chamber. A vacuum cleaner advantageously includes such a cyclone separation device.

Abstract: A teat for a bottle has a nipple portion at which there is a recessed valve portion. The valve portion is domed outwardly.

Abstract: A pump is for generating a suction for application to a vacuum cleaner dirty air inlet. There is a motor inside a motor outer casing and a fan outside the motor outer casing having a main inlet and a main outlet. The fan generates a main suction flow between the main inlet and the main outlet and creates a region of under pressure. This under pressure is used to drive a secondary flow between a cooling air inlet to the motor outer casing and a cooling air outlet from the motor outer casing. The secondary air flow is induced by making use of an under pressure generated by the fan.

Abstract: A wet vacuum cleaner uses a cyclone unit for separating liquid and particles from a suction flow. A main flow inlet to a cyclone chamber is spaced internally from its respective end by a separation distance. The separation distance is at least 0.1 times (effective/equivalent) diameter of the main flow inlet, which assists in preventing formation of large droplets which follows a path to a main flow outlet.

Abstract: A cyclone unit is for separating liquid and particles from a suction flow. A main flow inlet to the outer housing of the cyclone unit includes an opening. The transition between the main flow inlet and the outer housing at this opening has, at least for a portion of the opening, a radius of curvature of at least 0.5 mm. The large radius of curvature prevents the formation of static water drops.

Abstract: The invention describes a vortex finder for a cyclonic separator. The vortex finder includes a plurality of stationary vanes around which incoming air is guided into the vortex finder, in which a side of the vanes facing the incoming air is provided with a protrusion at a stagnation point. The protrusion is shaped so as to guide the incoming air into the vortex finder, and have a concave side following a shape of a neighboring vane, and a rounded top. Further, the protrusion has a height in a range between 70% and 130%, and in a range between 85% and 115% of a gap width between the vanes. The gap width between adjacent vanes increases from an outside to an inside of the vortex finder. A vacuum cleaner that includes a cyclonic separator has such a vortex finder.
