Abstract: A fluid recirculating cleaning device includes an exhaust port defining an exhaust port longitudinal axis, a fluid source end and an exhaust end defining a first cross-sectional area. A suction port includes a suction port longitudinal axis, a fluid exit end and a fluid entrance end defining a second cross-sectional area greater than the first cross-sectional area. The suction port includes a second outer surface that extends from the entrance end toward the fluid exit end. A vacuum blower motor sucks fluid in through the suction port to create fluid flow away from the vacuum motor and toward the exhaust port exhaust end. The exhaust port exhaust end is recessed from the suction port fluid entrance end and the two ports are located with respect to one another so that fluid flow from the exhaust port will be effectively drawn into the suction port.

Abstract translation: 流体循环清洁装置包括限定排气口纵向轴线的排气口，限定第一横截面积的流体源端和排气端。 吸入口包括吸入口纵向轴线，流体出口端和限定大于第一横截面积的第二横截面面积的流体入口端。 吸入口包括从入口端朝向流体出口端延伸的第二外表面。 真空鼓风机马达通过吸入口吸入流体，以产生远离真空马达的流体流向排气口排气端。 排气口排气端从吸入口流体入口端凹入，两个端口相对于彼此定位，使得来自排气口的流体流动将被有效地吸入吸入口。
