Abstract: An ergonomic vacuum-assist scraper tool has an arcuately curved head in which a scraper blade is mounted at either of a front position or a rear position, a handle or grip portion, and a tubular connector portion adapted to receive a male or female vacuum hose fitting. The head has a cavity defined between front and back walls, with the front and back walls converging along an arc to a mouth or slot opening. The grip portion is hollow and tubular, extending proximally from the head, to the vacuum hose-accepting tubular connector. A scraper blade can be removably mounted at either of the blade mounting positions. The tool is formed of upper and lower halves that snap together along a partition line.

Abstract: Liquid aspirator for drawing off and sucking up liquids, having a drawing-off lip, having a suction device for sucking up the liquid into a separating space in the housing of the liquid aspirator, having an exhaust-air channel, which is subjected to a negative suction pressure and is intended for leading the air out of the separating space, having a separating device, which is arranged in the separating space and separates the liquid from the water, and having a tank for accommodating the liquid. Complex guidance of the liquid/air stream is avoided in that the housing has a hollow chamber which forms the separating space and the tank, and into which the intake channel opens and from which the exhaust-air channel is guided out of the housing; wherein the hollow chamber contains a motor-driven rotor with a rotating impact surface, and the intake channel is designed such that the air/liquid stream is directed for radial direction reversal and acceleration onto the impact surface.

Abstract: The vacuum cleaner nozzle of the invention is provided with a nozzle body equipped with a suction pipe connecting piece and with a bottom plate which closes off the nozzle body towards the bottom, whereby at least one flow channel which is open towards the bottom and lets out into a central suction channel connected to the pipe connecting piece is located in the bottom plate. The flow channel is here double-parabolic in profile, meaning that it is parabolic in its cross section as well as in its longitudinal section extending perpendicularly to the bottom plate in relation to the longitudinal axis of the flow channel. The cross-section increases in this case from the bottom of the flow channel in the direction of the floor and from the end of the flow channel away from the suction channel in the direction of said suction channel. Thanks to this configuration of the suction channel, even distribution of the suction capacity is achieved over the entire width of the vacuum cleaner nozzle.

Abstract translation: 本发明的真空吸尘器喷嘴设置有一个喷嘴主体，该喷嘴主体配备有一个吸入管连接件和一个将喷嘴体朝向底部封闭的底板，从而至少有一个朝向底部打开的流动通道， 连接到管连接件的中心抽吸通道位于底板中。 流动通道是轮廓的双抛物线，这意味着它的横截面是抛物面的，以及在其相对于流动通道的纵向轴线垂直于底板延伸的纵截面。 在这种情况下，横截面在流动通道的底部沿着地板的方向和从流动通道的端部沿着所述吸入通道的方向远离吸入通道而增加。 由于吸入通道的这种构造，在真空吸尘器喷嘴的整个宽度上实现了均匀的吸力分配分配。

Abstract: A vacuum mop head having a scrubbing pad, a front squeegee in a front vacuum pickup slot, and a rear squeegee in a rear vacuum pickup slot has a vacuum outlet divided effectively between the two pickup slots. Side walls of a vacuum passageway extend downward from the top of the mop head and are covered by a plate that supports a liquid detergent dispensing system and encloses the vacuum passageway from the vacuum outlet to the front vacuum pickup. The upper half of the vacuum outlet evacuates the vacuum passageway to the front vacuum pickup, and the lower half of the vacuum outlet directly evacuates the rear vacuum pickup.

Abstract: A cleaner head for a cleaning appliance, comprising a brushbar, a housing defining a chamber which at least partially surrounds the brushbar, the chamber having a dirty air inlet and a dirty air outlet, and a scraper having a working edge which extends in the longitudinal direction of the brushbar. The scraper is arranged such that, in use, the working edge scrapes debris entrained by the brushbar from the brushbar. The working edge has a profile which is shaped such that debris which accumulates at the working edge is drawn by the airflow through the cleaner head along the working edge towards the dirty air outlet.

Abstract: A liquid vacuuming device for drawing off and vacuuming up liquids may include a housing (1), an extractor device formed by at least one extracting lip (7) for extracting and collecting the liquid in front of at least one vacuum mouth (5), a vacuuming device that features a motor-driven vacuum subassembly and is able to vacuum an air/liquid flow mixed with the liquid to be vacuumed up along a flow pathway from the vacuum mouth (5) through an intake channel (4) into the housing (1), a separating device (13) for separating the liquid from the air and a tank for receiving the separated liquid. The device may further include an on/off function that turns on the motorized drive or increases the motor power when pressure is exerted upon the extracting lip (7) and turns off the motorized drive or reduces the motor power when the pressure decreases. Similar functionality may be implemented by an orientation switch.
