  • Patent number: 11889961
    Abstract: A walk-behind floor microscrubber apparatus. The microscrubber includes as main subassemblies an upright handle assembly pivotally connected to a base assembly. The handle assembly includes components for recovering a cleaning solution applied to the floor during cleaning operations. The base assembly houses electrically powered motors for driving scrubbing brushes, and a clean solution reservoir. Spent cleaning solution applied to the floor is sucked to a recovery tank on the handle assembly. The microscrubber has features for avoiding vacuum motor flooding, including a specially-shaped recovery tank. Chambers in the recovery tank capture used cleaning solution when the handle assembly is tilted, thereby reducing the likelihood of solution travelling back to the vacuum motor. The microscrubber also has an exoskeleton reserve tank in the handle assembly.

  • Patent number: 11608836
    Abstract: A blower housing comprises first and second blower housing pieces for surrounding a blower fan. The first blower housing piece comprises a blower discharge section comprising an inner tubular portion, an outer tubular portion, and a drain hole. The inner tubular portion defines a blower discharge passage. The inner and outer tubular portions define an exhaust pipe cavity adapted to receive an end margin of an exhaust pipe. The tubular portions are adapted to enable condensate water that forms on the inner surface of the exhaust pipe to flow into the exhaust pipe cavity. The drain hole extends through the outer tubular portion. The drain hole is configured to enable condensate water flowing into the exhaust pipe cavity to drain from the blower housing. The first blower housing piece is a molded one-piece member.

  • Patent number: 11519413
    Abstract: An integrated flow source is a limiting factor in numerous microfluidic applications. In addition to precise gradients and controlling molecular transports, a built-in source of stable and accurate flow can enable novel shear stress modulations for long-term cell culturing studies. The Tesla turbine, when used as a pump on the microfluidic regime, produces stable and accurate fluid gradients by utilizing laminar flow between its rotating discs Utilizing a stereolithography based 3D printer, a tesla pump (Ø10 cm) and associated housing capable of driving a microfluidic gradient is provided having a printed rotor surface topology of the pump in order to enhance pumping of biological fluids like blood at elevated viscosities. The surface topology is tuned via 3D pixilation, and this modulation completely recovered the pressure loss between pumping water at 1 cP versus glycerol solution at 3 cP. As a result, increased fluid viscosities, and even Non-Newtonian viscosities, can be used.

The intake opening (5) determines a central axis of rotation for a fan wheel. An averaged half-spiral housing radius, as viewed about the axis of rotation (11), varies in the beginning portion (7), the center portion (8), and the blow-out portion (9). It reaches a maximum in the blow-out portion (9). The center portion (8) of the half-spiral housing radius is reduced in a region determining a maximum height H(?,z) of the half-spiral housing (1) compared to a logarithmic spiral radius (rlog).

  • Patent number: 11371532
    Abstract: An inlet collector for a centrifugal fan and a centrifugal fan are provided. By arranging a tragus-shaped section in a guiding section, reverse flow caused by intersection of inlet leakage flow at a volute tongue side and inlet airflow is blocked by the tragus-shaped structure in movement process, and the leakage flow no longer collide with the inlet airflow. An inner curved surface of the tragus-shaped section controls backflow to change smoothly along an inner wall surface of the tragus-shaped section and re-enter a volute for circulation. A tragus profile is adopted to guide the airflow to change more smoothly in the velocity direction near the wall of the guiding section, so as to effectively reduce the impact of the inlet airflow on the guiding section. By using the inlet collector, energy loss of airflow is reduced, vortex formation is suppressed, and aerodynamic performance and fan noise are improved.
