• intros：{"brand_intro":"素士（Soocas）是小米生态链企业，成立于2015年，专注于个人护理领域。品牌以\"科技美学\"为理念，主打高性价比和年轻化设计。素士的抛光杯刷头是其星钻系列电动牙刷的标配，采用自主研发的\"磁悬浮声波马达\"和\"杯形抛光刷毛\"技术。品牌注重用户痛点，如刷头更换成本高、抛光效果不持久等，通过优化刷毛密度和杯形弧度，在百元价位段提供了接近国际大牌的体验。品控方面，素士刷头通过SGS认证，刷毛磨圆率高达90%以上。","product_intro":"这款抛光杯刷头是素士星钻系列的核心配件，定位\"入门级美白抛光\"。核心卖点在于其\"双色杯形刷毛\"：外层白色刷毛负责清洁齿面，内层蓝色刷毛（含抛光微粒子）负责物理抛光。适用场景为日常美白、学生党/预算有限用户、初次尝试抛光刷头的人群。相比飞利浦和欧乐B，素士的抛光杯刷头价格仅为三分之一，但抛光效果稍弱，更适合轻度色素沉积用户。","key_specs":{"刷毛材质":"杜邦尼龙+蓝色抛光微粒子刷毛","震动频率":"39600次/分钟，磁悬浮声波马达","适配机型":"素士星钻系列（X3/X5等）及部分小米米家牙刷","更换周期":"3个月，刷毛褪色提示","刷毛磨圆率":"≥90%，通过SGS检测"}}
