摘要： A sub-suction pipe assembly for a vacuum cleaner includes an air suction pipe connected to a vacuum cleaner body, a sub-suction pipe connected to the air suction pipe and movable along the air suction pipe between a first position and a second position. The sub-suction pipe has a brush attached to an end thereof, a suction extension pipe detachably connected to the end of the air suction pipe, and a lock mechanism for securing the suction extension pipe to the air suction pipe. The sub-section pipe remains coupled to the end of the air suction pipe when the suction extension pipe is connected to the air suction pipe.

摘要： A vacuum cleaner has an electric motor driving an air impeller for creating a low pressure and a pump which draws liquid material through an inlet tube from the bottom of a tank and expels it from the tank. A priming apparatus is provided for priming the pump impeller. An outlet of the pump is connected to a discharge outlet carried by an upper vacuum assembly. Outlet piping connects the pump outlet to the discharge outlet. A pinch valve selectively closes the outlet piping to allow the priming apparatus to prime the pump. The pump and outlet piping are preferably carried by the upper vacuum assembly to facilitate conversion of the vacuum cleaner between wet and dry pick-up.

摘要： A portable surface cleaning apparatus including a base module for movement along a surface, an upright handle pivotally attached to the base module, a liquid dispensing system including a flexible bladder defining a fluid supply chamber for holding a supply of cleaning fluid, a fluid recovery system including a tank on the base module having a fluid recovery chamber for holding recovered fluid and housing the flexible bladder, and a fluid passageway between the fluid supply chamber and the recovery chamber, whereby the recovery chamber is in fluid communication with the fluid supply chamber and the pressure in the flexible bladder is equalized with the pressure in the tank as the cleaning fluid is dispensed from the supply chamber and the dirty liquid is collected in the recovery chamber. In a further embodiment the tank has an outlet opening in a bottom portion thereof and a drain plug is removably mounted in the outlet opening. In another embodiment a lid mounted on the tank defines an expansion chamber having an inlet opening, an outlet passage, and first and second diverters against which the working air flow reverses direction twice between the inlet opening of the expansion chamber and the tank. In another embodiment the working air conduit includes a manual actuator knob having an over-center linkage mechanism connected to a conversion valve for movement between first and second positions and thereby selectively moving the conversion valve between open and closed positions, whereby fluid communication between the tank and the suction nozzle is selectively opened and closed. In a further embodiment, a flow indicator is mounted to the base module and has a visibility window observable to a user and the flow indicator is disposed in the fluid supply conduit and is responsive to the flow of fluid through the fluid supply conduit to visually indicate the flow of fluid through the supply conduit to the user. Another embodiment includes a pump primer connected to the pump and having a housing defining a priming chamber with a valved opening connected to the vacuum source, an inlet opening connected to the fluid supply chamber, and an outlet opening connected to an inlet for the pump. A further embodiment includes a first mechanical connector extending between the motor drive shaft and the pump drive shaft, whereby the motor drives both the agitation brush and the pump. In a further embodiment, the base module includes an upper housing portion and a lower housing portion and an upright handle is pivotably mounted to the rear portion of the base module through at least one bearing for rotatable reception in the housing. In another embodiment, an elevator assembly is reciprocally mounted to the base module and movable in response to movement of the upright handle from an operative position to the upright position for upwardly pivoting a pivot arm mounting an agitation brush.

摘要： A surface cleaning and material removal system allows for the cleaning of applied or built-up coatings, debris, and any other matter from a surface. The surface cleaning and removal system includes a housing having a base with a wall extending obliquely therefrom. The base and wall define a cavity which covers the specific portion of the surface to be cleaned at that very moment, although the system is typically on wheels or portably movable so as to clean a very large surface in incremental portions. The system also includes a high-pressure-fluid mechanism for providing a high or ultra high pressure fluid flow against the surface to be cleaned where the mechanism includes either brushes or high pressure jets from which ultra high pressure water flows. In addition, the system includes a vacuum for moving all of the cleaning fluid and coatings, debris and any other matter from the cavity. In at least some of the embodiments, the system includes flexible members, seals, or brushes about the periphery of the walls extending obliquely from the base so as to better seal the cavity while still allowing for movement over the surface to be cleaned. In addition, more than one flexible member, seal or plurality of bristles or brushes may be present thereby defining a circumferential chamber therebetween which is fluidly connected to both the interior cavity and the environment so as to provide a better vacuum for better assuring that all of the cleaning fluids and coatings, debris, and any other matter are removed from the cavity and do not leak therefrom.

摘要： In order to keep the dimensions of the drive motor as small as possible in a combined high pressure cleaning and suction appliance incorporating a drive motor whose drive shaft drives both a high pressure pump and a suction fan, it is proposed that the drive shaft of the drive motor be connected to the high pressure pump and to the suction fan via a respective coupling, and that there be provided switching means which, on each occasion, selectively close one of the two couplings and open the other one.

摘要： A portable surface cleaning apparatus has a base for movement along a surface to be cleaned and an upright handle pivotally attached to a rearward portion of the base. A fluid dispensing nozzle for applying fluid to the surface and a suction nozzle for picking up fluid and debris from the surface are associated with the base. A clean water holding tank and a detergent holding tank are removably mounted to the handle while a recovery tank is removably mounted to the base. A mixing valve is fluidly connected between the holding tanks and the spray nozzle for changing the mixing ratio of the detergent with respect to the water. The fluid recovery tank includes an integrally molded conduit that extends from the suction nozzle and a mounting for an accessory hose that interrupts the fluid path from the suction nozzle in the conduit and redirects fluid flow through the hose. A pump is fluidly connected between the mixing valve and the dispensing nozzle and includes a pump priming valve that operates on negative air pressure to clear air from the fluid lines during pump operation. A free floating brush is pivotally attached to the base for automatically adjusting to different surface conditions during cleaning operations.

摘要： A pump has a housing defining a pump chamber and having a shaft opening. An impeller shaft extends through the shaft opening and is sized to define a gap between the impeller shaft and the shaft opening. An impeller is attached to the shaft inside the pump chamber. The impeller includes a first set of impeller blades for transporting fluid through the pump chamber and a second set of impeller blades for creating a pressure force which pushes fluid away from the shaft opening. The pump with sealless shaft prevents fluid from leaking through the gap, and therefore is particularly suited for use in a tank-type vacuum cleaner capable of collecting both dry material and fluid. The gap is used in such an application to prime the pump, thereby discharging fluid collected in the tank.
