• intros：{"brand_intro":"欧乐B（Oral-B）隶属于宝洁集团，1950年由美国牙医Dr. Robert Hutson创立，是全球最早的专业口腔护理品牌之一。其电动牙刷技术以\"旋转-振动\"为核心，每分钟可进行8,800次旋转和40,000次脉冲振动，被全球多国牙医协会推荐。欧乐B拥有全球最大的口腔护理研发中心，品控通过ISO 13485医疗设备认证，产品线覆盖从入门到专业级。品牌理念\"让每一次刷牙都像牙科诊所的清洁\"，强调科学刷牙方法。","product_intro":"EB50是欧乐B精准清洁系列的旗舰替换刷头，采用16度交叉植毛技术，刷毛呈X形排列，能深入牙缝和牙龈沟，配合旋转动作高效清除牙菌斑。其杯状刷头设计可包裹每颗牙齿，实现类似牙科抛光杯的清洁效果。适用于日常深度清洁、正畸护理及种植牙维护。相比飞利浦声波刷头，EB50的旋转动力更强，对顽固牙菌斑清除率更高，但噪音和震动感也更大。","key_specs":{"刷毛材质":"杜邦软毛，末端磨圆，含蓝色褪色指示刷毛","运动模式":"左右旋转8,800次/分钟 + 前后脉冲40,000次/分钟","适配机型":"欧乐B 3D系列电动牙刷（如P2000、Pro系列）","替换周期":"3个月（蓝色刷毛褪色提示）","防水等级":"IPX7"}}
