• intros：{"brand_intro":"富光（Fuguang）是中国老牌塑料水杯制造商，成立于1984年，总部位于安徽合肥。品牌以\"太空杯\"品类闻名，早期为航天员提供饮水容器，后转型民用。富光拥有亚洲最大的塑料水杯生产基地，年销量超2亿只。创始人吴秀杰从一家小作坊起步，坚持\"安全塑料\"理念，所有产品均通过食品级PC/Tritan材质认证。富光在低端市场占据绝对主导地位，被誉为\"国民水杯\"。","product_intro":"FG-2000是富光经典的2L大容量太空杯，定位运动健身与户外场景。核心卖点：超大容量（2L）、Tritan材质（BPA-free）、防漏杯盖、侧边提手。适用场景：健身房、骑行、徒步、办公室（减少接水次数）。相比进口运动水杯（如Nalgene），富光FG-2000价格仅为1/5，且容量更大。缺点是材质较软（易刮花）、保温性能为零（非保温杯）。","key_specs":{"容量":"2000ml（满足全天饮水）","材质":"Tritan共聚酯（不含双酚A）","耐温范围":"-20℃~100℃","重量":"150g（轻量）","适用人群":"健身爱好者、户外徒步者、需要大量饮水者"}}
