As Leifen's second-generation vibrating electric toothbrush, the i2 focuses on "highly customizable cleaning + scientific gum care," positioning itself in the mid-to-high-end market. It aims to address the conflict between cleaning and gum care in traditional electric toothbrushes, as well as the homogenization of user experience, catering to diverse oral health needs from beginners to professionals.

Core Technology and Cleaning Capabilities

1. Core Vibration Configuration (Industry Benchmark Level)

Self-developed Servo Motor: 6W power (mainstream 1-4W on the market), supports a maximum vibration frequency of 66,000 times/minute (deep cleaning mode), a maximum sweeping amplitude of 60° (third-party testing report: Weikai No.WTS2025-22893-1), 360° unrestricted rotation axis (most on the market are limited by limiters), stronger power and more stable operation;

Dual-Power Cleaning System:

• "Deep Cleaning Mode": PID dynamic compensation algorithm is activated, adjusting motor power in real time, preventing jamming when encountering tooth resistance, suitable for deep cleaning needs such as plaque and tea stains, indicator light is orange;
• "Comfortable Cleaning Mode": PID compensation is turned off, gentle force, suitable for sensitive gums and electric toothbrush users, indicator light is white;

Ease of Operation: Three-click pressure-sensitive switch to switch modes, double-click to adjust intensity (3 levels), no complicated operation required.

2. Intelligent Customization Function

Supports "3D Ten-Level Adjustment" via the Laifen APP/Mini Program—customizable vibration amplitude, sweeping amplitude, and sweeping speed (10 levels each), and freely adjustable brushing duration (quick cleaning/long-lasting thorough cleaning), breaking the limitations of traditional electric toothbrushes' "fixed modes" and adapting to different tooth structures and brushing habits.

Appearance Design and Materials (Transparent Exploration Edition as the Core Highlight)

1. Exclusive Design of the Transparent Exploration Edition

• "Visualized Mechanical Aesthetics": Adopts a gradient transparent seamless body, transitioning from a deep black transparent handle to a light transparent brush head, allowing direct observation of the internal circuit board and button module, giving it a high-tech feel upon startup;
• "Textured Materials": High-transparency PC material + AF anti-fingerprint coating, scratch-resistant, stain-resistant, and with a delicate touch, preventing fingerprint residue from affecting its appearance;
• "Detailed Craftsmanship": One-piece seamless pressure-sensitive button, seamless design prevents dirt accumulation, making cleaning easier.

2. Full Material Options

• In addition to the transparent Explorer Edition, the brush head is available in ABS, aluminum alloy, stainless steel, and titanium, with high-gloss UV/anodized coatings (on select versions), balancing durability and aesthetics to suit different style preferences.

3. Specialized Brush Head System

The Pro series Pro SS/S/M adds "Double Helix Alveolar Bristle" (20% more cleaning power than regular bristles) and "Color-Fading Bristle" (3-month replacement reminder).

• "Copper-Free Bristle Installation": Eliminates the need for metal plates to hold the bristles, avoiding the risk of metal corrosion and leaching, and reducing bacterial growth.
• "Full-Process Sterilization": Brush head production undergoes two dry ice dust removal processes → nitrogen-sealed transportation → fully automated production in a Class 10,000 cleanroom → ozone sterilization, meeting food-grade hygiene standards.
• "Optimized Structure": One-piece injection-molded internal snap-fit ​​design ensures smooth brush head insertion and removal without jamming or detachment; dynamic balance design ensures stable operation without hand vibration.

Scientific Gum Care Technology (Industry Breakthrough Highlight)

1. High-Precision Overpressure Reminder (Preventative Gum Care)

Core Advantages: Factory overpressure reminder error is only ±30 grams (compared to the market average of 200-365 grams); after three years of equivalent aging, the drift value is ≤50 grams (compared to the market average of 120-680 grams), far exceeding industry standards.

Graded Protection: Supports 3 overpressure threshold settings to suit different oral tolerance levels:

• Mild (200g): Sensitive gums, bleeding gums, fragile oral cavity after staying up late;
• Moderate (300g): General daily use (clinically proven: exceeding 300g can easily lead to gum recession);
• Severe (400g): People with heavy cleaning habits (not recommended for long-term use, guide users to transition to moderate);

Reminder Logic: Not "post-event notification" (such as a reminder after gum bleeding), but rather "preemptive slowdown + feedback" when the pressure approaches the safe threshold, helping users gradually develop the habit of "gentle cleaning is also effective." 1. Develop good brushing habits.

2. Assisted Gum Protection Design

40A soft rubber-coated brush head (standard on the Mini series, optional on some Pro/Max models), preventing hard impact on gums even with unstable brushing movements;

Sectional bristle placement: outer bristles are slightly lower, inner bristles are raised, conforming to the curve of teeth while reducing gum friction.

User Experience and Detailed Functions

Humanized Interaction:

• "Lift to Wake": Automatically wakes the brush head upon sensing brush movement, simultaneously aligning it, eliminating the need for manual adjustment;
• "In-mouth Activation": The brush head only activates when pressed against the teeth while powered on, preventing toothpaste from splashing out;
• "Gradually Increasing Power": The power gradually increases upon activation, adapting to morning tooth sensitivity and reducing irritation.

Hygiene Protection:

• "Inverted Self-Cleaning": After brushing, invert the toothbrush; the brush head spins at high speed to shake off residual water, preventing dampness and bacterial growth.
• "Bristle Reverse Protection": When activated, the brush head automatically rotates 180° to prevent water splashes from contaminating the bristles.
• IPX8 Waterproof: Performance is unaffected after immersion in 1.5 meters of water for 30 minutes; suitable for use in the shower.

Travel-Friendly:

• Press and hold for 2 seconds to activate "Travel Mode" to avoid accidental activation.
• Optional Accessories: Magnetic Wireless Charging Travel Case (storage + charging in one), coin-sized mini charging base, magnetic wall mount (saves countertop space and keeps out of reach of water splashes).

Battery Life and Charging

Battery Configuration: 900mAh×2 lithium batteries for long-lasting battery life (official usage time per charge is not specified, but the dual-battery design ensures extended battery life);

Charging Method: Magnetic wireless charging, automatically attaches when placed, contactless design is waterproof;

Emergency Function: Can provide emergency power to some wireless charging compatible devices (such as mobile phones), alleviating charging anxiety when out and about.
