Description

一种能同时称量两种物体的电子秤 技术领域
本发明涉及电子秤技术领域，特别是涉及一种能同时称量两种物体的电子秤。
背景技术
电子秤是用来称量物体重量的装置，目前大多数电子秤一次只能用来称量一种物体，当需要同时称量两种物体时，电子秤的使用就收到了限制。但是，对于一些物品在配制或使用过程中，需要能同时称量两种物体的电子秤以提高配制精度。例如，在咖啡冲泡中，对于手冲咖啡来说，市面上大多数电子秤无法同时单独称量注水总重量与获得的咖啡液重量两个数值；对于意式咖啡来说，市面上大多数电子秤无法同时测量同时萃取出的左右两杯咖啡各自重量，但上述数据对于使用者能够制作出优质的咖啡都具备重要意义。市面上有具备双传感器的电子秤产品有可能实现上述功能，但在一个机身里安装两个传感器，会造成产品内部结构复杂化，成本增加等问题。因此，设计出一款能同时称量两种物品重量的电子秤很有必要。
发明内容
为了解决上述现有技术中的不足，本发明的目的在于提供一种能同时称量两种物体的电子秤，该电子秤仅靠单个传感器即可实现同时称量两种物体的重量，可应用于在咖啡冲泡等领域，以提高配制精度。
本发明解决其技术问题所采用的技术方案为：
提供了一种能同时称量两种物体的电子秤，包括电子秤本体，所述电子秤本体包括壳体、手冲架及壳体上方的秤盘，所述壳体内安装有双头传感器，所述双头传感器与所述壳体上的控制面板电连接，所述双头传感器设有两个称量端；第一称量端通过支架与所述手冲架底端连接，第二称量端顶部通过衬垫与所述秤盘底部接触。利用一个传感器即可实现对两种物体的称量，同时称量两种物体能够实时得到准确的质量，双头传感器感应出的质量实时的显示出来， 供使用者观察，减少配置过程中的误差，该结构适用于手冲咖啡的冲泡。
进一步的，所述支架位于所述第一称量端的一侧，所述壳体与所述支架对应的位置设有凹槽，所述支架穿过所述凹槽与所述手冲架连接。手冲架上放置过滤装置，第一称量端称量出残留在过滤装置中的咖啡液的质量，过滤装置中存留的咖啡液重量与第二称量装置得到的已滤出咖啡液重量相加，即为注水总量，以此作为参考计算咖啡浓度、调整注水速率，起到减少计算误差，保证咖啡口感的效果。
一种能同时称量两种物体的电子秤，包括电子秤本体，所述电子秤本体包括壳体及壳体上方的秤盘，所述秤盘包括两个，所述壳体内安装有双头传感器，所述双头传感器与所述壳体上的控制面板电连接，所述双头传感器设有两个称量端；两个称量端顶部分别通过一衬垫与上方的两个所述秤盘接触。可将两个咖啡容器分别放在两个秤盘上，第一称量端及第二称量端分别称量两个咖啡容器中注入的液体的重量，实现对称量过程的准确控制，该结构适用于意式咖啡的冲泡。
与现有技术相比，本发明的有益效果在于：仅靠单个传感器就可以同时对两种物体进行称量，提高咖啡配制的精确度。
