Cleaning Filter Means TRIZ Cases

Bottom recesses and raised sections restrain debris motion in a vehicle vacuum tank, cutting noise during acceleration, braking, and turns.

A helical cyclone expansion region separates airflow near the separator plate, reducing dirt re-entrainment as the bin fills.

A top-entry vacuum tank and shut-off suction path help collect liquid manure with less spillage and more stable suction during filling.

A magnetic follower and pressurization member visualize dust fullness, helping users empty cyclone containers before suction drops or motor load rises.

A pivoting steering joint and spherical rolling assembly improve canister vacuum stability, direction changes, and obstacle navigation.

Electrochromic transparency lets a bagless vacuum dust container hide dust deposits yet reveal the filling level when needed.

Fresh filter media advances across the exhaust grill to replace clogged sections, maintaining airflow and reducing vacuum filter maintenance.

Tangential dual inlets and a shared airflow path improve cyclone barrel separation while reducing space use and dust buildup.

Debris-catching tines stop hair from wrapping around cyclone exhaust grill openings, preserving airflow and simplifying debris removal.

Sloped mating surfaces convert filter housing rotation into transverse dirt cup movement, simplifying secure attachment and removal.

A nested wheel-and-sidewall layout protects the cyclone and post-motor filter while keeping a vacuum cleaner compact and stable.

A cyclone separator and rotating dust compressor increase vacuum dust capacity while reducing scattering during tank removal and discharge.

A transparent sealed filter compartment lets users inspect vacuum filters without disassembly while sidewalls shield the cyclone bin from impacts.

A nested two-stage cyclone with a tapered inlet and helical vanes boosts fine debris separation and reduces re-entrainment in vacuum airflow.

Compressed air cleans enclosed smoke, heat, and CO detectors while filtered airflow captures debris and test gas verifies detection.

A Y-shaped flap and single-solenoid control direct pulse cleaning air to each vacuum filter half with lower energy loss and simpler actuation.

A pressing and cleaning assembly compresses dust in the container, increases capacity, and prevents debris from getting caught.

A removable handle and canister layout improves vacuum maneuverability in tight spaces while enabling above-floor cleaning with accessory tools.

A linear cyclone-to-motor airflow path cuts backpressure, raising airflow without a larger motor in a compact hand vacuum cleaner.

A rotating brush and drop guide clear dust from the mesh filter into a collector, maintaining airflow and avoiding manual cleaning scatter.

A wheel-nested cylindrical dirt container and two-stage cyclone layout save space while preserving dust separation, stability, and maneuverability.

A bent double-wall conduit with a closed air pocket lengthens the noise path and damps variable blower noise while preserving airflow.

A pivoting filter cover moves battery and filter replacement to the clean side, simplifying vacuum cleaner maintenance and keeping batteries away from dirt.

A spring-loaded flush inlet opens under slight foot pressure to collect debris efficiently while reducing bending and accidental activation.

A cam-linked intake and communication valve layout cleans filters during operation without electrical control, cutting dust collector complexity and cost.

A radially interlocking bin connection and single actuator reduce flex and simplify emptying in a handheld cyclonic vacuum.

A flexible pleated filter collapses and twists to dislodge dust without water, reducing clogging and maintaining vacuum cleaning capacity.

Pivoting the handle rotates engaged coarse and fine filters to shake off debris, enabling hands-free filter cleaning and compact storage.

Spacing the dust collection chamber away from the cyclone casing lets heavier particles exit laterally and improves vacuum cleaner separation efficiency.

An intermediate debris container bypasses the truck debris body, cutting unload stops, truck repositioning, and lane blockage in vacuum collection.

A vacuum lock holds the water receptacle without fasteners, simplifying filter cleaning and reducing leakage risk near the motor.

Multiple cyclone flows in one chamber improve dust separation while cutting parts, airflow losses, and manufacturing cost.

Reverse airflow cleans a clogged downstream vacuum filter, while an auxiliary separator captures released dust to maintain suction and cut replacements.

Vacuum pressure pulls the lip seal inward to keep the dust container airtight despite cover and receptacle tolerance variation.

A bleed air valve bypasses a clogged pre-motor filter to keep airflow reaching the suction motor while reducing seals and housing leakage.

A clean-side support part stabilizes the filter unit against vibration, preventing unfiltered air bypass and reducing filter damage.

An off-centre dirt bin inlet increases cyclone collection capacity and limits dirt re-entrainment through reduced flow disturbance.

Lip seals let a detachable vacuum dust receptacle keep air-tight inlet and suction connections while reducing seal wear during non-axial removal.

An inclined cyclone layout with counter-rotating currents keeps the vacuum cleaner compact while preventing dust from scattering upward.

Reciprocating projections sweep the filter surface to remove dust evenly, cutting pressure loss while keeping the vacuum dust collector compact.

A variable-cross-section dirt chamber interrupts cyclone airflow so particles settle instead of re-entering the stream and fouling the suction motor.

A segmented dust collector uses brush sweeping, blower suction, and a backflow flap to capture heavy and light dust without a larger fan motor.

A wand release actuator and lock simplify vacuum wand removal and reinsertion while keeping the upper portion compact and ergonomic.

A fixing member shifts the hidden inner filter during removal, making both dust cup filters visible and easier to clean.

By routing the outlet duct between adjacent cyclone bodies, this case cuts separator size, removes the manifold, and maintains filtration performance.
