Household Water Flosser ODM | 350ml IPX7 Oral Irrigator Custom

1. Project Overview

This private-mold D60 cordless oral irrigator is customized for global oral care startup founders, hardware R&D engineers, cross-border e-commerce sellers and hotel amenity brands. It upgrades the traditional small-capacity water flosser by adopting a 350ml detachable large water tank, dual-thread high-frequency pulse water technology and 4 adjustable cleaning modes, solving user pain points of frequent water refilling, weak plaque removal, single pressure mode and inconvenient tank cleaning.

2. Core Development Difficulties & Targeted Technical Countermeasures

Difficulty 1: 350ml Large Detachable Tank Leakage Risk & Internal Space Layout Restriction

Pain Point: Enlarged 350ml tank increases internal water storage volume; the split detachable structure is prone to water leakage at the assembly seam; limited handheld shell space makes it hard to arrange pump, battery and circuit board together.

Solutions:

Multi-layer thickened silicone sealing ring at the tank joint, passed thousands of disassembly and assembly leakage tests; layered internal structural partition design, miniaturized high-efficiency water pump to reserve enough space for the large-capacity detachable tank, and the split tank design is easy to disassemble for deep cleaning of residual dirt.

Difficulty 2: Dual-Thread Pulse Water Jet Stability & Efficient Plaque Removal Algorithm

Pain Point: Ordinary single water column has weak cleaning force and cannot penetrate interdental gaps and gingival pockets; high-frequency pulse is easy to produce water flow jitter and unstable pressure output when switching different modes.

Solutions:

Self-developed dual 0.3mm twin water column pump structure, form concentrated cross pulse water flow; independent frequency conversion chip for 4 modes, stabilize 1400–1800 pulse frequency under 30–120PSI pressure, improve plaque removal rate up to 99.99%, while avoiding gum stabbing irritation.

Difficulty 3: 4 Modes Multi-Gear Control Logic & Clear Human-Machine Interaction

Pain Point: Compact handle only reserves one mode switching button, which is easy to cause misoperation; mode indicator light is dim, and users cannot quickly distinguish cleaning gears under bathroom dim light.

Solutions:

Single-button cyclic mode switching logic with independent LED indicator for each mode; optimized PCB layout to enhance indicator brightness, with clear text marking of Soft/Normal/Strong/Pulse on the handle panel, convenient for beginners and sensitive gum users to quickly switch gears.

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

Pain Point: Bathroom shower splashes and residual water on the tank easily infiltrate the charging port, leading to circuit short circuit; long-term wet environment causes charging contact failure.

Solutions:

Hidden enclosed Type-C charging port with integrated waterproof rubber plug; the whole machine shell adopts ultrasonic seamless welding technology; internal circuit board is coated with waterproof conformal coating to realize IPX7 full waterproof, allowing the whole device to be rinsed directly.

Difficulty 5: Low Noise Control Under High-Speed Pump Operation

Pain Point: Large flow high-frequency pump generates strong vibration noise, disturbing family members during morning and night oral care, exceeding 75dB without structural optimization.

Solutions:

All-round shock-absorbing silicone bracket wrapped around the water pump; internal flow channel silencing structure design, reduce water flow collision resonance noise; overall machine noise controlled below 72dB under standard 30cm testing distance.

3. Core Product Differentiated Selling Points & Competitive Advantages

350ml Detachable Large-Capacity Water Tank
Compared with the common 150ml mini tank on the market, one full tank of water can complete full-mouth cleaning without repeated refilling; transparent split tank is easy to take apart and wash to avoid bacterial residue inside the tank.
High-Efficiency Dual-Thread Pulse Water Flow
Dual parallel 0.3mm water columns produce cross impact pulse, deeply flush food debris hidden between teeth, around braces and implants, effectively remove dental plaque and whiten teeth without hurting gingival soft tissue.
4 Customizable Professional Cleaning Modes
Soft: Low pressure for sensitive gums, orthodontic beginnerNormal: Daily conventional deep cleaning

Strong: High pressure for heavy plaque and teeth stain removal
Pulse: Alternating pressure massage to boost gum blood circulation

IPX7 Full-Body Waterproof & Wide Global Voltage Adaptation
Suitable for shower, bathroom wet environment, can be fully washed directly; 100–240V wide voltage design, compatible with power supply standards of all countries, ideal for cross-border sales and travel carrying.
Ultra-Low Noise Design (<72dB)
Optimized pump shock absorption and flow channel silencing structure, quiet operation will not disturb family rest in early morning and late night.
Complete Multi-Functional Nozzle Kit
Comes with 5 interchangeable rotating nozzles, covering daily cleaning, orthodontic braces, tongue coating cleaning, periodontal care and nasal washing multiple oral care demands, matching family multi-person use scenarios.
Full Brand Private Customization Support
Independent exclusive private mold without shared public shell; customizable shell color, LOGO silk printing, mode pressure parameter tuning, outer packaging box design; assist clients to apply CE/RoHS/ETL global export certifications.
