在本发明第一实施方式中，所述挡块300的数量为一个，所述定量称取装置10设定一个称取量，当所述物料的加入量达到该称取量时，所述挡块300运动到所述光电开关400的发射极与接收极之间，将所述光电开关400断开，并输出一个光电感应信号，当接收到该光电感应信号时，停止加料。在本实施方式中，可以使用圆柱支杆220或转轴230作为所述摆动支点。
请一并参阅图2和图5，在本发明第二实施方式中，所述挡块300的数量为多个，所述多个挡块分隔设置于所述摆杆的一端，每一所述挡块与所述摆动支点之间的距离均相同，且所述多个挡块具有相同的运动路径。所述多个挡块可以等间隔设置。所述多个挡块的尺寸宽度可以相同。
所述定量称取装置10设定多个递增的称取量，该多个挡块300分别与所述多个递增的称
取量对应，随着所述物料的加入，该多个挡块300对应所述称取量依次运动到所述光电开关400的发射极与接收极之间，并依次输出一个光电感应信号，即该多个称取量输出的光电感应信号数量不同，通过设定接收的光电感应信号数量来选取所述称取量，当接收到所述设定的光电感应信号数量时，停止加料。
在一实施例中，所述多个挡块300为依次分隔设置于所述摆杆210一端的第一挡块311、第二挡块312、第三挡块313、第四挡块314和第五挡块315。所述第一挡块311、第二挡块312、第三挡块313、第四挡块314和第五挡块315分别与7g、10g、14g、17g和20g的称取量对应。所述多个挡块300的尺寸宽度一致。当所述物料的加入量达到7g时，第一挡块311运动到所述光电开关400的发射极与接收极之间，输出第一个光电感应信号，若此时继续加料，当所述物料的加入量达到10g时，第二挡块312运动到所述光电开关400的发射极与接收极之间，输出第二个光电感应信号，以此类推。例如要称取17g的物料，在称取之前，设定所要接收的光电感应信号数量为4，进行称取时，当接收到4个光电感应信号时，停止加料，则此时所述装料器100中物料的重量为17g。
请参阅图6，所述定量称取装置10进一步包括按钮组件610，该按钮组件610包括多个按钮，该多个按钮分别与所述多个递增的称取量对应，通过按下所述按钮设定每次称取所要接收的光电感应信号的数量。

所述定量称取装置10设定多个递增的称取量，多个所述L1:L2值分别与所述多个递增的称取量对应，即所述多个支点位置分别与所述多个递增的称取量对应，通过调节所述支点位置来选取所述称取量，当所述物料的加入量达到所述称取量时，所述挡块300运动到所述光电开关400的发射极与接收极之间，将所述光电开关400断开，并输出一个光电感应信号，接收到该光电感应信号时，即停止加料。
在一实施例中，所述摆杆210设有第一支点位置、第二支点位置、第三支点位置、第四支点位置和第五支点位置，其分别与7g、10g、14g、17g与20g的称取量对应。例如要称取17g的物料，在称取之前，将所述摆动支点设置在第四支点位置，进行称取时，当接收到光电感应信号时，即停止加料，则此时所述装料器100中物料的重量为17g。
在本实施方式中，可以使用圆柱支杆220作为所述摆动支点。
请一并参阅图8，所述定量称取装置10进一步包括按钮组件620，该按钮组件620包括
多个与分别所述逐渐递增的称取量对应的档位以及拨动按钮622，所述拨动按钮622与所述圆柱支杆220连接，通过调节所述拨动按钮622至不同的档位，来将所述圆柱支杆220设置在不同的所述支点位置。

在研磨咖啡时，所述咖啡粉通过所述出粉口32漏出并落入所述装料器100，所述摆杆210开始摆动并带动所述挡块300运动，当该挡块300运动到所述光电开关400的发射极与接收极之间时，断开所述光电开关400，形成光电感应信号输出，从而将所述磨豆组件30的研磨量转化为光电感应信号。根据所述光电感应信号控制所述磨豆组件的研磨。
在一个实施方式中，所述挡块300的数量为一个，所述咖啡机设定一个研磨量，当达到该研磨量时，所述光电开关400输出所述光电感应信号，所述磨豆组件20停止工作。
