Abstract:
A cyclonic cleaning stage for a, e.g., surface cleaning apparatus is provided. The cyclonic cleaning stage comprises a plurality of cyclones, which are integrally molded as a single body. Each cyclone has a cyclone body having an upper end, a lower end, a cyclone inlet, and a cyclone outlet. Each cyclone inlet has a top. A separately molded upper cover is mounted to the top of the single body at the upper ends. A separately molded lower cover is mounted on the single body at the lower ends of the cyclones.
Abstract:
A portable vacuum cleaner having at least first and second cleaning stages wherein the first cleaning stage has a dirt collection member and the second cleaning stage comprises a plurality of cyclones and at least one dirt collection chamber, wherein the first and second cleaning stages are emptied separately. One cleaning stage can be removably mounted from the vacuum cleaner without removing another cleaning stage.
Abstract:
An ostomy bag in which an ostomy bag is supported on the user's skin by a combination of an inner sealing means to secure the stoma in the opening of the ostomy bag and an outer securing member spaced from the inner sealing means. The outer securing member is positioned adjacent the outer perimeter of the bag to secure the bag to the skin of a user. A water transport and or a chafing protection layer may be provided between the skin of the user and the ostomy bag.
Abstract:
A surface cleaning head (12) for a vacuum cleaner has a bottom wall (28) having a dirty air inlet (34), a brushing member (32) associated with the dirty air inlet (34) and a dirt collection area (38) positioned downstream from the dirty air inlet (34) and configured to retain particulate material in the dirt collection area (38). The dirt collection area (38) has an upstream end and a downstream end, the downstream end having a smaller cross section than the dirty air inlet (34). The downstream end has an air outlet (46), which is in airflow communication with a source of suction, and at least one filtration member when the vacuum cleaner is in use.
Abstract:
An apparatus using thermomechanical means for signalling the concentration of a reactive gas is disclosed. The thermomechanical means uses movement of a mechanical member to produce a signal corresponding to the concentration of the reactive gas in a gas stream. The method and apparatus may include means for converting a specific gas in a gas stream to a reactive gas. The apparatus may then provide an analog readout of the concentration of the specific gas.
Abstract:
A vacuum cleaner (20) includes a cyclone separator (38) and an electrostatic precipitator (40) downstream of the cyclone separator (38) in the air flow path through the vacuum cleaner (20). The electrostatic precipitator (40) includes a washable filter element (40) enclosed in a housing (42) that is removable from the vacuum cleaner (20) as a unit. The housing (42) protects a user from contact with the dirty filter element (40) and has water inlet (62, 74) and outlet openings (42A, 74) through which water can be directed to flush dirt from the filter element (40).
Abstract:
A surface cleaning apparatus (10) comprising a member having a dirty fluid inlet (12), a fluid flow path extending from the dirty fluid inlet to a clean air outlet (14), a portable cleaning unit (16) positioned in the fluid flow path and comprising a cyclonic separation stage (18) and a suction motor (20), and a wheeled base mounted to the portable cleaning unit, the wheeled base (58) having at least one front wheel (66) and two rear wheels (68a & 68b)
Abstract:
A surface cleaning apparatus (10) comprising a member having a dirty fluid mlet (12), a fluid flow path extending from the dirty fluid mlet to a clean air outlet (14), a portable cleaning unit (16) positioned in the fluid flow path and comprising a cyclonic separation stage (18) and a suction motor (20), and a wheeled base mounted to the portable cleaning unit, the wheeled base (58) having one front wheel (66) and two rear wheels (68a & 68b)
Abstract:
A surface cleaning apparatus is disclosed. The surface cleaning apparatus comprises a dirt inlet, a clean air outlet and a fluid flow path extending between the dirt inlet and the clean air outlet. The surface cleaning apparatus further comprises first and second side by side housings. The first housing comprises a cyclonic cleaning stage in the fluid flow path. The cyclonic cleaning stage comprises a cyclone having a dirt outlet. An associated dirt collection chamber is positioned below the dirt outlet. The dirt collection chamber extends under at least a portion of the first and second housings. The surface cleaning apparatus further comprises a fluid flow motor in the fluid flow path.
Abstract:
A cleaning head for a surface cleaning apparatus has a plurality of struts extending from a front chamber having a dirty air inlet to a rear chamber having a transition duct that is in communication with a filtration apparatus of a surface cleaning apparatus by a dirty fluid outlet. One or more of the struts comprises an airflow passage. In one embodiment, no outer casing is provided surrounding the struts.
