Cleaning Filter Means TRIZ Cases

Three serial cyclone stages separate large, medium, and fine dust to improve vacuum suction without relying on a simple two-step separator.

A built-in compressing member packs dust to extend bin capacity, while a lower cover enables quick bottom discharge with less frequent emptying.

An elastomeric cap expands over the mounting post and contracts to lock the vacuum filter in place, speeding replacement while preventing leakage.

A curved detachable battery pack wraps around the dirt container to shrink cordless vacuum size while preserving handling and cyclone separation.

Reinforcing ribs and a varying dirt chamber cross-section cut down-duct vibration, reduce noise, and improve fine dirt separation.

A barrier piece and divided chambers create a slow-flow zone that disperses dirt away from the suction inlet and extends vacuum cleaning time.

Conductivity probes and a simple control circuit shut off the vacuum motor before rising water reaches the filter and causes damage.

By separating the plate from the door and using a pivoting door, the dirt chamber empties cleanly without blockage or trapped debris.

Circumferential fins and a helical step guide separated debris downward, reducing re-entrainment and improving cyclonic dirt collection.

A sloped false bottom, drain outlets, and bottom door let debris slide out without tilting the vacuum box, avoiding rollover risk.

Separate dust inlets and storage spaces reduce fan burden and filter clogging in robot cleaners while making dust removal easier.

A spring-loaded closing device opens on installation and seals the inlet on removal, simplifying manufacture while containing dust.

A tab-and-slot filter interlock stops filter removal while mounted, helping prevent unfiltered motor operation and airflow loss.

A flexible cyclone tip vibrates during use to dislodge dirt, prevent clogging, and maintain fine dust separation in surface treating appliances.

Modular hopper filtration combines panel and cyclonic stages through a common interface, improving dust control while cutting conversion and maintenance complexity.

Stored mechanical energy snaps open a filter valve to create a pressure pulse that clears dirt buildup and restores vacuum suction.

Separate dust regions and a backflow flap help a low-suction robot cleaner capture bulky and light dust without discharge.

A spring-assisted lock and push mechanism lets the extension pipe release upward with one hand during upright-to-canister conversion.

A two-stage cyclone with an air manifold and dirt cup improves dust separation, simplifies assembly, and reduces filter replacement needs.

A keyed top plate and lock mechanism let users replace vacuum filter bags easily while blocking non-standard bags that can reduce safety and reliability.

An attachment-linked shutter closes the cleaner bin inlet before removal, preventing dust spills and enabling external suction cleanup.

A filter-cake-free area around the inlet keeps the closing flap unobstructed, improving dust retention and odor absorption.

A lower nozzle and straighter vertical airflow path cut back-pressure, improve cyclone separation, and support smaller hand vacuum motors.

Separate locking points retain the dust bin and filter casing during tilting while keeping mounting, demounting, and fabrication simple.

Multiple separation passages and tangential airflow remove liquid before it reaches the vacuum, while a float valve shuts off suction as the tank fills.

A removable lid component exposes the wet/dry vacuum filter for cleaner replacement without unlatching the lid, tipping the unit, or releasing debris.

A single compact HEPA exhaust filter merges multiple motor airflows to trap carbon dust while reducing bulk, cost, and maintenance effort.

A collapsible vacuum filter and rod-cleaning mechanism remove trapped dust into the container, limiting spread while maintaining suction.

A gravity-biased dust bag mount blocks cover closure when the bag is missing, avoiding spring installation cost and wear.

A two-stage cyclone and HEPA layout removes fine dust while reverse pulse cleaning cuts filter clogging and maintenance.

Filtered exhaust is redirected through the cord reel to cool the power cord without carbon powder contamination or hard-to-access filter cleaning.

A universal wiper coupler fits track, pin, and bent-tab arms, cutting replacement variants while preserving beam blade performance.

Larger side wheels shield the cyclone bin from impacts, improve carpet travel, and preserve easy access to filters and internal parts.

A movable pressing member compacts dust in the container, increasing capacity and enabling easier discharge through a rotating lower cover.

A servomotor-driven Y-shaped flap separates filter-half cleaning from flap actuation, cutting energy loss and strengthening pulse cleaning.

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

A rigid collar with alignment voids and a rotating mount secures upright vacuum bag installation while reducing parts and leakage risk.

Compressed dust is wetted and solidified inside the collector, cutting volume and preventing lightweight dust from scattering during disposal.

A deformable blocking ring with a V-shaped slit keeps airflow and suction stable when a power tool suction head tilts against the workpiece.

A movable body rises through dry dust by vibration-driven kinematic sorting, restricting airflow when the vacuum dust chamber is full.

A motor-driven eccentric shaker cleans vacuum filters in place, reducing clogging and debris spread while locking securely to the filter cage.

An external openable dirt chamber lets the cyclone empty without internal obstructions, reducing particle re-entrainment and user effort.

A rotatable main body and steering device transmit turning force to the wheels, reducing wrist strain during upright vacuum direction changes.

A combined separation and tank chamber directs the intake stream onto a rotor to separate liquid from air without bulky storage or exhaust backflow.

A sealed hopper and dump tank with an isolation valve let vacuum dust be emptied or bagged without shutdown, suction loss, or dust re-circulation.

Sliding sleeve ports let a low-pressure reverse air jet clean vacuum filters effectively while cutting energy use, weight, and condensation.

A removable exhaust grill and fines catcher let a cyclone vacuum be emptied and maintained one-handed without tools.

Bottom-mounted optical sensing in a cyclone chamber detects dust buildup when the bin is full while avoiding sensor contamination and false alerts.

A two-stage cyclone and annular separator removes fine dirt before the motor and filter while reducing airflow noise and duct vibration.
