360° Rotary Electric Toothbrush ODM Project Case

1. Project Overview

This private-mold rechargeable rotary electric toothbrush is developed for global oral care startup brands, cross-border e-commerce sellers, travel product distributors and home appliance retailers. It adopts a 360° rotating brush head, high-torque magnetic levitation motor, IPX8 full waterproof design and 3-mode intelligent cleaning logic, solving common pain points such as incomplete tooth surface coverage, weak plaque removal, short battery life and limited wet-environment use.

2. Core Development Difficulties & Targeted Countermeasures

Difficulty 1: 360° Rotary Brush Head Cleaning Coverage vs. Bristle Comfort

Pain Point: Ordinary sonic toothbrushes often miss interdental areas, gingival margins and back teeth. A rotating brush head must cover multiple surfaces while avoiding excessive gum irritation.

Solutions:

Adopt a 360° round rotary brush head with high-density soft nylon bristles. The bristle tips are rounded and polished to reduce gum damage, while the rotary motion wraps around each tooth surface for more uniform cleaning coverage.

Difficulty 2: High-Torque Motor Stability and Noise Control

Pain Point: High-frequency rotation may cause strong vibration, handle noise and unstable power output, especially during long-term use.

Solutions:

Use a high-torque magnetic levitation motor with integrated brush rod and motor shaft structure. Optimize internal counterweight and shock-absorbing silicone parts to stabilize power transmission, reduce handle vibration and lower operating noise.

Difficulty 3: IPX8 Waterproof While Maintaining Magnetic Charging Reliability

Pain Point: Bathroom splashes, shower steam and long-term water exposure may penetrate the charging base or handle gaps.

Solutions:

The handle adopts fully sealed ultrasonic welding. The magnetic charging contact area is designed with hidden waterproof structure, and the charging base uses inductive contact charging, realizing IPX8 waterproof performance for both daily washing and short-term soaking scenarios.

Difficulty 4: 70-Day Long Standby Battery Management

Pain Point: Users expect long battery life for travel and business trips, but high-frequency motors consume more power.

Solutions:

Equip an intelligent power management IC with optimized sleep current and automatic power-off logic. The magnetic charging base provides stable energy replenishment, and the low-power operation strategy extends standby life to 70 days on a single charge.

Difficulty 5: 3-Mode Control Logic and User-Friendly Indication

Pain Point: Multiple modes need to be clearly identified in a compact handle, but too many buttons increase waterproof risk and operation complexity.

Solutions:

Use a single multi-function button with cyclic mode switching and LED indicator for each cleaning mode. The PCB layout is optimized to reduce component size, while tactile feedback ensures easy mode selection even with wet hands.
