Cleaning Filter Means TRIZ Cases

Strip-based diffusers with oblong openings spread incoming air and dust through the bag, reducing inlet blockage and extending filter bag life.

Pressure-driven dust compression packs foreign matter inside the collector, reducing scattering during vacuum cleaner disposal.

Concentric cyclone sets raise vacuum separation efficiency without enlarging diameter, while flexible outlets help prevent blockage.

A tangential-inlet separator and vertical standpipe improve liquid and debris removal while limiting pressure drop and foam in wet extraction cleaners.

A pressure pulse routed through the suction channel cleans the sweeper filter with less external air while preventing escape through the suction shaft.

Compressed dust storage in a removable separator cuts scattering during emptying while keeping vacuum dust handling lighter and easier.

A single lever-driven slide mechanism replaces multiple bucket buckles, keeping a secure seal while speeding dust bucket removal and reattachment.

A pivoting separator and spherical rolling assembly improve canister vacuum maneuverability, stability, and obstacle avoidance.

A removable liner bag and divider plate let cyclone vacuums contain dust and liquid for cleaner emptying without carrying the whole unit.

Automatic alignment and anti-rotation locking keep an upright vacuum stable in storage while allowing easy conversion to floor cleaning.

Air-guide means form a rotating air column that deflects heavy particles away from the separator, preventing damage without blocking airflow.

A switchable air path keeps the separator out of normal suction flow, cutting resistance, energy use, and noise while enabling reverse filter cleaning.

A wrapped hose and nested tool holder shrink vacuum cleaner size while protecting accessories and keeping the cyclone bin easy to remove.

A dual-stage cyclonic dirt cup uses a transparent shroud and single-wall layout to improve debris separation, clog visibility, and maintenance.

A door-mounted bag retainer with a living spring lets users remove and discard a full floor cleaner filter bag without direct contact.

An external filtration chamber moves the screen outside the cyclone, reducing clogging and enabling cleaning without opening the cyclone chamber.

Routing the air duct between domed wheel rims cuts vacuum body height, improves stability, and helps maneuver through tight spaces.

By nesting the suction unit inside the cyclone chamber, this case cuts vacuum cleaner volume while preserving effective dust separation.

A rear-mounted handheld unit and transparent cyclone bin let users switch cleaning modes and check dust without moving to the front.

A bottom-mounted dust box and optimized suction path raise suction pressure while cutting noise, power use, and motor count.

A spring-biased pivot assist helps a vacuum handle return to center, reducing steering effort and user fatigue from handle weight.

A removable bag door with an integrated carry handle improves filter bag replacement while keeping the dust cavity securely closed.

A nested two-stage cyclone layout cuts vacuum cleaner size and airflow losses while improving fine dust separation and easy bin emptying.

An interlocked shutter closes the dust inlet before detachment, preventing debris spill and enabling external suction cleanup.

A domed wheel and yoke layout routes ducting through the rolling assembly to improve vacuum cleaner maneuverability in tight spaces.

A thick coarse upstream layer traps brick and plaster dust before the fine filter, extending suction time and reducing clogging during cleanup.

A recessed hose wrap and tool holder shrink vacuum cleaner storage space while protecting the hose and accessories from impact.

A deflector fin strengthens helical vortex flow in a compact vacuum cyclone, improving dust separation while reducing filter maintenance.

A handle-driven wheel carriage shifts closer to the air inlet during use, improving upright vacuum steering and direction changes.

A hinged bottom wall and biased movable plate increase cyclone dirt capacity while easing emptying and limiting airflow back pressure.

A cam-actuated latch converts button press into vertical latch movement, making vacuum dirt cups easier to secure and remove.

An openable cyclone and dirt chamber layout exposes both chambers together, clearing trapped debris in one emptying step.

Vertical pivot receivers let the filter bag drop in and rotate into place, avoiding alignment jams and dust-clogged slide channels.

A magnet-held external air valve opens rapidly to shake and backflush the filter without unintended cleaning during suction.

Uses a suction nozzle, canister, and duct to collect animal waste with a standard leaf blower while limiting clogging and accidental discharge.

A spring-loaded valve and resilient stop admit brief external airflow to clean vacuum filters without noticeable suction interruption.

Asymmetric alignment members guide the removable cyclone bin into the correct position and orientation, preserving airflow during replacement.

A pivoting battery pack counterbalances an extendable air duct, improving handheld vacuum reach, ergonomics, and dust separation.

An elastic integrated seal closes multiple cyclone interfaces at once, cutting air leakage, cost, and vibration-related detachment.

A front-openable removable dirt chamber and axial cyclone-motor layout let dirt empty cleanly without touching vacuum parts.

A rotatable filter and dust discharge member return detached filter dust upstream, preserving suction and avoiding valve-related pressure loss.

An integrated suction channel, dust collector, and adaptive fan control improve granular dust pickup while lowering power use and noise.

A separate filter housing and downstream screen capture larger debris while keeping the cyclone outlet clear and reducing filter maintenance.

Brief electromagnet-driven valve opening sends counterflow air through the filter, cleaning it without fully losing suction.

A sensed tool outlet and notched door keep the vacuum running with the power tool and briefly after shutoff for more complete debris cleanup.

A nested dust chamber around the cyclone and motor boosts dirt capacity in a compact vacuum while preserving airflow and extending filter life.

A split cyclone chamber floor and sidewall keep airflow sealed during use while allowing cleaner dirt emptying with less debris retention.

A gravity-lifted indicator senses airflow and pressure in low-suction cleaners without blocking the passage or requiring a stronger motor.

A shared mounting member makes the cyclone stage and suction motor removable, simplifying upright vacuum repair while reducing weight.
