Cleaning Filter Means TRIZ Cases

A pivoting bottom flap empties dust cleanly into a bin, while a motor-driven rotating filter brush helps maintain suction.

A sealed lid port, flexible closure, and suction source contain dust plumes and draw fine allergens back into the refuse container.

Automatic inlet cleaning keeps a water-assisted vortex dust collector from clogging in paper-making, sustaining capture reliability and lowering fire risk.

A startup valve keeps dust out of the cyclone path until airflow is high enough to form a vortex, preventing downstream filter clogging.

A hinged housing swings open to access an angled vacuum cleaner filter and integrated dedusting parts without kneeling or extra removal steps.

Rotating the removable cyclone container knocks dust off the fine filter without disassembly, helping maintain vacuum suction during cleaning.

A detachable dust container and station lever open a sealed disposal port to transfer dust cleanly while limiting leakage.

Pressure sensing opens a clean gas valve to reverse airflow and back-clean a vacuum cleaner filter without stopping suction.

Intermittent motor-driven vibration sweeps a broad frequency range to clear floor sweeper filter plates and reduce cleaning downtime.

Relative motion during dust bin removal cleans the filter automatically, helping maintain suction without motor-driven cleaning parts.

Recaptured exhaust air is redirected in reverse flow to backflush vacuum filters, dislodge trapped debris, and maintain air quality with less complexity.

Pressure-drop and airflow data are combined to detect true filter clogging, avoiding false cleaning from hose or flow-path blockages.

Integrated handle controls adjust bleed air and brush speed together, improving rug cleaning while preserving cyclone airflow stability.

A dual-unit refuse holder separates collection from storage to increase vacuum capacity, limit airborne dust, and keep airflow effective.

An external filtration chamber moves the screen outside the cyclone, reducing clogging cleanup while preserving separation efficiency.

A diamond cleaning head combines fan spray, rotating-handle control, and vacuum suction to clean tile, grout, and soft surfaces without damage.

Threshold-based cleaning triggers when airflow drops and motor load rises, maintaining vacuum suction while avoiding excess energy use.

By moving the inlet onto the shroud and directing flow away from perforations, this case improves dirt separation and reduces spiral interference.

A cyclone separator, front dirt door, and openable filter cover simplify debris emptying and pre-motor filter maintenance without tools.

A rib-based cover interlock blocks closure when the vacuum filter is missing, preventing fine dust from reaching the fan motor.

A guided coarse separator and pivoting bottom flap let bagless vacuum bins empty cleanly with less dust spread and easier cleaning.

A spring-loaded air inlet releases stored energy to create a pressure surge that clears a clogged vacuum filter and restores suction.

A movable dust removal unit contacts the drum brush to clear tangled hair and dust while preserving brush rotation and cleaning efficiency.

A yoke-based moment arm shifts handle force ahead of the base, cutting floor friction and making upright vacuums easier to push on carpet.

A dual-use push bar lets users move the vacuum cleaner and lower the dirt container while standing, with spring-assisted torque control.

An integrated hood outlet channel with a silencer cuts pulsating suction noise while preserving compact assembly and mechanical stability.

Movable side wheels expose nested compartments for filters and cyclone parts, improving vacuum cleaner access without sacrificing compactness.

A nested dirt chamber uses empty space around the cyclone and motor to increase capacity without enlarging the vacuum cleaner.

Reversing the axial fan after suction backflows air through the filter to clear dust automatically, maintaining suction power without extra cleaning parts.

A water receptacle with guided air exits traps fine dust in water, avoids sponge-filter odors, and helps keep moisture away from motor parts.

Recessed chamber sidewalls disrupt dirty airflow to improve cyclone dirt separation, limit re-entrainment, and reduce vacuum noise.

Combining rotating brushes on different axes with stationary bristles improves fluid agitation, carpet grooming, and single-pass cleaning.

Support bars reinforce the upright vacuum housing while leaving most of the dust container visible for easy inspection and emptying.

A compressible strip and non-reactive lubricant create a rotatable airtight coupling that improves vacuum steering and traps dirt.

A detachable cyclone dust collector uses a cover and anti-scattering path to empty dust cleanly without re-contaminating indoor space.

A sidewall-protected cyclone bin with an adjacent release member enables one-handed removal while keeping the vacuum mounted securely.

Rotating brush fibers scrape dust into a vacuum intake, preventing re-deposition while keeping the handheld dust remover self-cleaning.

An asymmetrical two-part dirt chamber and diverter wall reduce cyclone re-entrainment and improve particulate collection in surface cleaners.

A spring-biased pedal lock holds a vacuum tool securely in up or down positions while simplifying engagement and release with one consistent motion.

An elastic filter frame combines mounting and sealing in a vacuum cleaner lid, cutting parts, easing filter exchange, and maintaining airflow.

A wheel-side filter compartment with a transparent seal plate enables quick inspection and replacement while keeping the vacuum compact and stable.

Removable side wheels open filter and cyclone compartments, preserving a compact vacuum layout while simplifying inspection, cleaning, and replacement.

A movable shield closes the dust bin air inlet when suction stops, preventing backflow, clogging, and unsanitary dust release.

An electromagnet-timed valve injects external air pulses to counterflow-clean the filter while maintaining near-continuous suction.

A motor-driven cleaner moves against a pleated vacuum filter to limit clogging, maintain suction power, and reduce dust exposure.

Nested second cyclones inside the main cyclone improve dust separation while keeping the vacuum dust collector compact and serviceable.

Reverse airflow and switchable sub-separators clean clogged vacuum filters automatically, reducing user effort and extending filter life.

Compressed dust storage and dual cyclone separation increase vacuum collecting capacity while reducing disposal frequency and re-pollution.

A knob-driven ramp moves the lift assembly to set inlet height for different surfaces, improving debris pickup without complex linkages.

Oblong diffuser strips spread dust-laden airflow inside a flat vacuum cleaner bag to prevent inlet blockage, cut pressure loss, and extend bag life.
