Liquid Spraying Apparatus TRIZ Cases

A mist blower nozzle directs liquid onto a facing body to resolve inconsistent atomization and achieve stable particle sizes.

A portable joint-compound texture sprayer uses a battery-powered reciprocating pump to deliver material for drywall finishing.

Dual-channel airflow control reduces liquid wastage and back pressure while enabling variable fan pattern adjustment in HVLP spray guns.

An electric pump pressurizes a detachable tank while a relief valve prevents rupture, eliminating manual effort.

A disposable gas diffusion device uses a pneumatic compression element to create a negative pressure zone for liquid conveyance.

Segmenting the device into a shared main body and replaceable applicator heads reduces production complexity while maintaining versatile watering capabilities.

A combined spray and vacuum nozzle design with side-by-side passages enables effective thermoplastic powder application.

A fluid feeding system stabilizes discharge pressure through controlled valve timing and pump activation.

A spring-loaded diaphragm maintains the pressure differential across the oxidizer inlet to ensure stable combustion during deep throttling maneuvers.

Segmented passages restrict and expand airflow to eliminate non-uniform spray patterns caused by pressure variations.

Segmented casings isolate the piezoelectric actuator from liquid, preventing vibration energy absorption and corrosion.

Integrated nozzle assembly directs pressurized air at compound angles against liquid flow to resolve uniformity issues in difficult-to-atomize slurries.

Spherical geometry and specific spacing prevent reflected waves from damaging ultrasonic vibrators, ensuring high durability.

A spray device uses interchangeable mixer devices with varying choke diameters to control liquid and air proportions.

Curved end walls minimize storage volume for spray gun reservoirs without compromising external access to ventilation components.

A nozzle body directs pressurized atomizing gas angularly away from the spray axis to enhance liquid flow rate and atomization efficiency.

Resiliently mounted elastomer valve opens upon pressure differential to admit air, eliminating the need for a separate flexible liner inside the reservoir.

Merging drive and collecting nozzles into one unit prevents abrasive wear from widening the stream channel, preserving pressure and conveying efficiency.

Laser drilling creates high-density aperture plates for precise aerosol generation.

A removable cartridge cap assembly integrates a venturi insert to aerosolize liquid compounds within air treatment appliances.

Aroma diffuser nebulizer mounts externally via a ring for easy oil bottle replacement.

Replaceable paint guide device uses outer surface geometry to form a secure seal against the spray gun base.

A fragrance diffuser system uses a droplet delivery mechanism to atomize customizable essential oil blends via piezoelectric vaporization.

A pneumatic spreading device uses a blower assembly to propel cremated remains through a conduit for controlled discharge.

A spray gun apparatus with vertical and horizontal movement delivers controlled paint deposition.

Miniaturized silicon ultrasonic nozzle devices produce monodisperse droplets using external liquid transport and multiple Fourier horns.

A tapered adapter connects a closed fluid reservoir can to an applicator, eliminating disposable mixing cups and reducing waste.

A hybrid powder spray gun handles dilute and dense phase flows through a single nozzle.

A trigger head cap uses a rotatable oval stopper to hold the stem down and prevent accidental spraying.
