• intros：{"brand_intro":"雷瓦（Riwa）是中国本土美发工具品牌，成立于2006年，总部位于浙江宁波。品牌以\"高性价比\"和\"快速迭代\"著称，产品线覆盖卷发棒、直发器、吹风机等。雷瓦在电商渠道表现强势，尤其在天猫和拼多多拥有大量用户。其品控理念是\"让每个人都能用上专业美发工具\"，虽然技术积累不如国际大牌，但凭借价格优势和本土化设计，在中低端市场占据重要份额。","product_intro":"雷瓦 RB-835A 是一款入门级负离子卷发发刷，采用陶瓷釉涂层加热板，并内置负离子发生器。其刷头设计类似传统发梳，可同时梳理和卷发，适合快速打造自然微卷。核心卖点是\"百元内\"\"负离子护发\"和\"防烫设计\"。相比松下 EH-KA31，雷瓦价格更低，但负离子浓度和温控精度稍弱。竞品如金稻、康夫的同价位产品在刷头材质和耐用性上略逊一筹。","key_specs":{"加热板":"陶瓷釉涂层（导热均匀，减少卡发）","温度范围":"120-200℃（5档调节）","负离子":"低浓度负离子（约500万/cm³）","防烫设计":"隔热刷头外壳，避免烫伤头皮","适用发质":"所有发质（尤其适合细软发）","功率":"35W"}}
