Rotasonic 牙刷：一个伺服电机，实现多种清洁动作

Rotasonic 牙刷：一个伺服电机，实现多种清洁动作

A rotasonic toothbrush is Relish Tech’s flagship brushing platform. A single servo motor drives a shaft that can swing through selected angles from 0 to 360° or rotate in a full circle. This flexible drive supports sweep, oscillation and sonic vibration, with whitening and polishing actions on the 5-in-1 configuration. This guide explains the technology and compares the two Rotasonic platforms.

什么是 Rotasonic 牙刷？

Rotasonic combines rotation and vibration through one servo motor. Its drive shaft can swing through selected angles from 0 to 360° or make a full rotation, allowing a rotasonic toothbrush to support several cleaning actions on the same platform. The enabled actions depend on the model and configuration.

The Rotasonic platform combines sonic vibration, sweeping and oscillation, with whitening and polishing on the 5-in-1 model. This range of movements gives brands a clear all-in-one product story and room to build different configurations.

一个电机，五种清洁动作

伺服轴的灵活运动让同一把Rotasonic 牙刷能够切换不同清洁动作，而不局限于固定行程。

各类清洁动作如何发挥作用

• Sonic. Bristle motion at 31,000 vibrations per minute (VPM) cleans through direct contact and moves liquid and foam around the teeth and gumline.
• 扫动。低频扫动使刷毛扫过牙面，直接刷洗牙齿表面。
• 往复摆动。刷头在较大角度内来回摆动，形成传统往复旋转式牙刷的清洁轨迹。
• 美白。专门的清洁动作针对牙齿表面着色，帮助牙齿看起来更亮洁。
• Polish. A full 360° rotation provides a polishing action. The brush head or polishing attachment should match the selected product configuration.

The product pages specify a rotation speed of 900–2,300 RPM and a sonic vibration rate of 31,000 VPM. Rotation and vibration are distinct measurements; together they describe the movement capabilities of the Rotasonic platform.

Rotasonic、Vibrosonic 与声波牙刷的区别

These platforms use different combinations of movement. Sonic brushes clean through vibrating bristles and the liquid movement they create. Relish Tech’s Vibrosonic platform combines sonic vibration with a 60° oscillation. Rotasonic uses a servo shaft that can swing through selected angles or rotate fully, supporting sweep, oscillation and sonic actions, plus whitening and polishing on the 5-in-1 model.

Illustrative Comparison of the Three Platforms

Research on powered toothbrushes provides useful background. The American Dental Association (ADA) explains that both manual and powered toothbrushes can clean effectively. The 2014 Cochrane review by Yaacob and colleagues found benefits for powered brushing in plaque and gingivitis outcomes. A 2020 review of powered-toothbrush design discusses how construction and use affect performance. These sources address the wider category rather than a clinical evaluation of Rotasonic. For the dual-motion platform, see our guide to Vibrosonic technology.

Rotasonic 产品系列

Both Rotasonic configurations include an LCD smart display, a 2,000 mAh battery with a stated runtime of up to 30 days, and an IPX8 waterproof rating. Runtime depends on the brushing settings and usage; the IPX8 specification follows the depth and duration defined for the model.

• VS0560B（三合一）结合扫动、往复摆动和声波振动，提供5+1种清洁模式，支持无线及 USB-C 充电，旋转速度为每分钟900–2,300转。
• VS0661C（五合一）是旗舰配置，在扫动、往复摆动和声波振动的基础上增加美白与抛光动作，并支持磁吸壁挂及 Type-C 充电。

两款产品均支持 OEM 和自有品牌合作，可基于同一Rotasonic 牙刷核心平台，按品牌需求定制颜色、刷头和包装。

伺服驱动轴带来的变化

The practical value of the Rotasonic design is flexibility. Brands can configure enabled actions, mode profiles, displays and finishes around their market and retail positioning. The servo-driven platform supports a range from sweep, oscillation and sonic vibration to the 5-in-1 model with whitening and polishing, giving OEM buyers more than a single fixed specification to work with.

面向品牌：Rotasonic 平台

For OEM and private label buyers, the Rotasonic toothbrush is a distinctive flagship option within the electric toothbrush range. Its combination of cleaning actions and visible LCD features suits brands developing a premium lead product.

Rotasonic 为什么适合作为旗舰系列

• 突出多功能优势。“一个刷头实现五种清洁动作”是单一运动牙刷难以提供的零售卖点。
• 提供三合一与五合一两个层级。VS0560B 与 VS0661C 让品牌在同一平台下同时布局入门款和旗舰款。
• 以 LCD 显示屏形成差异化。智能屏幕实时显示刷牙数据，是消费者可以直观看到的高端功能。
• 匹配品牌外观与毛材。Pantone 配色和硅胶加尼龙刷毛，便于与品牌现有产品保持一致。

On commercial terms, the standard MOQ for customized products is 1,000 units; smaller orders may be discussed case by case. Wholesale orders for in-stock products start at 50 units. Samples ship in 3–7 days, and mass production runs 25–35 days after approval; a one-time mold fee of $500–$3,000 applies only to a new custom casing and is fully refundable once cumulative orders reach 5,000 units within 12 months. The factory is ISO 9001 and ISO 13485 certified with FDA establishment registration, and can supply CE, RoHS, FCC, and UKCA documentation plus EU design-patent coverage for the platform.

Those specifications are measured rather than quoted. Our own reliability laboratory, which has logged more than 450 test items over nine months, verifies the servo-driven motion stroke by stroke on every unit, confirms the sonic vibration rate to a factory specification of 30,000 ± 3,000 strokes per minute, and runs each handle through a 72-hour full-unit life test, immersion testing per GB 4208-2017, and 48-hour salt spray per GB/T 2423.17-2008. The 3.7 V lithium cell in the handle was cycle-tested at 0.5 C to a ≥80 % retention acceptance criterion at 300 cycles and measured 98.6 % of its initial capacity. This result records cell-capacity retention under the stated test conditions. Reports are available on request.
