- Elastic Sanitary Insert Unit for Variable-Diameter Shower Fittings
An elastic sleeve head lets a sanitary insert lock into different shower line diameters while enabling flow regulation or backflow prevention.
- Fixture Shut-Off and Bypass Valve for Instant Hot Water
A temperature-controlled shut-off and bypass valve recirculates cooled water to deliver hot water faster while reducing drain loss and energy waste.
- Hot Water Shut-Off Valve Assembly for Tepid Water Recirculation
A fixture-side shut-off and bypass valve recirculates cooled water and limits tepid discharge, cutting hot-water wait time, waste, and pump energy.
- Rotary Water-Saving Valve for Aerated and Spray Flow Switching
A rotatable switch holder lets one faucet valve alternate between aerated water saving and higher-pressure spray cleaning without replacement.
- Thermosensitive Water Flow Control for Stable Shower Mixing
A thermosensitive assembly and diaphragm adjust warm water flow as cold water temperature changes, keeping shower outlet temperature stable with gas heaters.
- Rotatable Water Pipe Adapter for Toilet Tank Interference Avoidance
A pivotable two-joint water pipe adapter reorients toilet tank connections to avoid pipe interference while keeping sealing and connection stability.
- Thermostatic Shower Flow Control Module for Variable Cold Water
A thermosensitive assembly and diaphragm vary warm water flow as cold water temperature changes, keeping thermostatic shower mixing stable.
- Electronic Bidet Flush Adapter for Tank and Direct Valve Toilets
A stepper-motor flush adapter lets one electronic bidet work on tank and direct valve toilets while reducing water hammer and pressure loss.
- Bubbler Flow Controller Structure for Stable High-Pressure Output
Multi-stage elastic legs distribute water pressure in a bubbler flow controller to prevent support fracture and keep outlet flow stable.
- Discrete-Step Faucet Valve for Selectable Water Flow Limits
Rotating calibrated holes sets fixed faucet flow limits without throttling upstream shut-off valves, helping conserve water and avoid deposit buildup.
- Shower Water Diversion Control for Reuse Without Pressure Loss
Temperature-based diversion captures cold shower water for storage and reuse while preserving flow, pressure, and real-time monitoring.
- Shower Flow Restrictor Web Structure for Low-Noise Throttling
Non-parallel web planes deflect water through multiple stages, cutting shower flow and noise without amplifying structure-borne sound.
