背景技术
咖啡作为世界三大饮品之一，具有消除疲劳、美容皮肤、利尿除湿和减肥等功效，现如今咖啡越来越受到人们的喜爱。咖啡粉与水的比例和咖啡的萃出率均会影响咖啡的口感，咖啡的萃出率受到冲泡时间的影响，因此在滴滤咖啡的制作过程中，操作者需要实时称量注水的总重量，以此为依据调整自己的注水速率。现在人们通常在分享壶底部放置一台普通的电子秤，用来称量已滤出咖啡液的重量，以此来作为注水总重量。当前电子秤称量注水总重量的方法存在以下问题：
在制作滴滤咖啡时，水注入与滤出的过程有时间差和流量差，实时称量的已滤出咖啡液的重量要小于实时的注水总重量，误差较大；咖啡粉、咖啡滤纸自身也有吸水特性，注水总重量与已滤出咖啡液重量这两个数据并不相等。因此，用现有的电子秤称量的已滤出咖啡液的重量代替注水总重量，以此为依据计算咖啡浓度、调节注水速率时会存在很大的误差，影响咖啡的口感。
