• intros：{"brand_intro":"科西（Keheal）是中国新兴家电品牌，成立于2018年，总部位于深圳。品牌以\"健康空气解决方案\"为定位，专注于负离子、净化与静音技术。科西的创始团队来自华为和格力，强调\"技术下沉\"，将高端功能（如负离子净化）引入中端价位。其品控采用\"零缺陷\"标准，每台产品出厂前经过72小时老化测试。虽然品牌年轻，但凭借高性价比和差异化功能，迅速在电商平台走红。","product_intro":"科西A2是一款集成负离子净化功能的静音风扇，定位为\"健康与静音兼顾的性价比之选\"。核心卖点包括：负离子发生器（可沉降PM2.5和细菌）、双层21片扇叶（风感更细腻）以及低至20分贝的噪音。适用场景为卧室、母婴房等对空气质量敏感的环境。相比戴森，其价格仅为六分之一，但负离子净化效果有限；相比美的，多了净化功能且风感更柔和。","key_specs":{"噪音范围":"20-45分贝（最低档几乎无声）","负离子浓度":"300万/cm³","扇叶设计":"双层21片（内外层交错）","电机类型":"直流变频电机","功率":"28W","控制方式":"遥控器 + 手机App"}}
