2. Core Development Difficulties & Targeted Technical Countermeasures

Difficulty 1: Foldable Retractable Water Tank Sealing & Capacity Balance

Pain Point: Foldable tank structure easily causes water leakage at telescopic joints; limited mini size cannot balance sufficient 180ml water storage and compact folded travel volume.

Solutions:

Multi-layer silicone ring sealing design for the retractable tank joint, anti-leakage after thousands of folding cycles; optimized internal partition layout to maximize 180ml storage while shrinking folded size, convenient to put into travel bags and makeup pouches.

Difficulty 2: Wide 50–130PSI Stepless Adjustable Water Pressure & Multi-Mode Stable Pulse Output

Pain Point: Conventional oral irrigators only have fixed gears, unable to adapt sensitive gums, deep cleaning and orthodontic care demands; pulse frequency fluctuates sharply when switching pressure modes.

Solutions:

Self-developed variable-frequency water pump drive chip, realize smooth 50–130PSI pressure regulation; independent algorithm for each working mode (Soft/Normal/Strong/Pulse/DIY/UV), stabilize 1350–1800 pulse frequency to avoid water jet jitter and pressure sudden drop.

Difficulty 3: Low Noise Control Under High-Speed Water Pump Operation

Pain Point: High-frequency water pump vibration produces loud noise, disturbing users during morning and night oral care; noise exceeds 75dB easily without structural optimization.

Solutions:

Integrated shock-absorbing silicone bracket wrapped around the water pump; internal airflow silencing channel design; optimize water flow channel to reduce water collision noise, control whole machine noise below 72dB at 30cm testing distance.

Difficulty 4: IPX7 Full-Body Waterproof While Ensuring Stable Type-C Charging

Pain Point: Water splashes and residual water in the tank easily seep into charging port, causing short circuit; charging contact failure after long-term wet environment use.

Solutions:

Hidden enclosed Type-C charging port with integrated waterproof rubber plug; whole shell ultrasonic seamless welding; internal circuit board conformal coating anti-water treatment, achieve IPX7 full waterproof for shower and bathroom wet environment use.

Difficulty 5: Safe BPA-Free Material Molding & Multi-Color Mass Production Consistency

Pain Point: Food-grade BPA-free ABS has poor fluidity during injection molding, easily leads to shell shrinkage and surface defects; mass production of multi pastel colors has obvious color difference.

Solutions:

Custom modified food-grade ABS raw material formula to improve molding fluidity; unified substrate pre-treatment process before color injection; independent color calibration for each pastel color (blue/white/pink/green), full appearance inspection to eliminate color difference in mass orders.

3. Core Product Selling Points & Competitive Advantages

Foldable Retractable Mini Travel Design
Telescopic foldable water tank greatly reduces storage volume, easy to carry for business trips, camping and travel; 180ml capacity meets complete single oral cleaning without frequent water refilling.
6 Multi-Scenario Working Modes
6 optional modes cover all oral demands: Soft mode for sensitive gums, Normal for daily cleaning, Strong for heavy plaque, Pulse for gum massage, DIY adjustable pressure, UV mode for nozzle disinfection, suitable for orthodontic braces, implant and family daily care.
50–130PSI Adjustable Pulse Water Jet
1350–1800 high-frequency pulse water flow flushes food residue hidden between teeth and gum pockets, effectively remove plaque without scratching gum tissue.
Food-Grade BPA-Free Safe Material
Whole water contact parts adopt BPA-free food ABS plastic, no harmful substance precipitation, safe for long-term oral contact use for adults and teenagers.
Low Noise & IPX7 Full Waterproof
≤72dB quiet operation avoids noise disturbance; IPX7 waterproof allows whole machine direct flushing and shower use, easy daily cleaning and maintenance.
Long-Lasting 1100mAh Battery & Universal Type-C Charging
Large 1100mAh lithium battery supports long cycle use; universal Type-C 5V/1A charging compatible with power bank, phone charger and laptop USB ports, convenient global travel charging.
Full Brand Customization Support
Independent private mold without shared public shell; customizable shell color, surface LOGO printing, mode parameter tuning, nozzle matching and color box packaging; assist clients to apply CE/FCC/RoHS overseas export certifications.
