• intros：{"brand_intro":"素士（Soocas）是小米生态链企业，成立于2015年，专注于个人护理科技。创始人孟凡迪曾是华为工程师，带领团队以\"极致性价比\"切入市场，打破国际品牌垄断。素士的核心技术是磁悬浮声波马达，震动频率达39600次/分钟，同时采用IPX7级防水和Type-C快充。品牌理念是\"科技美学\"，产品设计多次获得德国iF奖和红点奖。在牙齿美白领域，素士凭借亲民价格和高效美白功能，迅速成为年轻消费者的首选，被誉为\"电动牙刷界的价格屠夫\"。","product_intro":"X3U定位入门级美白电动牙刷，核心卖点是高性价比和高效美白模式。其美白模式通过高频震动配合杜邦软毛刷头，有效去除牙渍。适用场景包括学生党、职场新人、初次使用电动牙刷者。相比飞利浦和欧乐B，素士的优势在于：1）价格仅为国际品牌的1/5；2）续航长达30天；3）赠送旅行盒和6个刷头。缺点是美白模式力度单一，缺乏智能交互功能，刷头磨圆率略低于高端品牌。","key_specs":{"震动频率":"39600次/分钟","模式数量":"4种（清洁、美白、敏感、抛光）","刷头类型":"杜邦软毛刷头（无铜植毛）","电池续航":"30天","充电方式":"Type-C快充","适配人群":"预算有限、追求基础美白效果的年轻用户"}}
