Title: Coffee Scale

Description:
FIELD OF THE INVENTION 
     The invention relates to a weighting device technical field, more particularly relates to a kind of coffer scale. 
     BACKGROUND OF THE INVENTION 
     Coffee scale is used to measure a weight of coffee power, a flow rate of water and a water amount adding to the coffee power in the process of brewing coffee, thereby controlling the flow rate of water and the water amount, and the ratio of the coffer power and the water so as to accurately control the consistency and taste of coffee. 
     The common coffee scale has a display screen on the scale plate, where the weighed value is displayed. When brewing coffer with this kind of coffer scale, the user must add water and coffer power into the container placed on the scale plate, and stir them while observing the weighed value displayed on the display screen. Sometimes, the display screen is blocked, the user can not observe the weighted value, which easily causes mistakes, for example, sprinkling water on the scale plate or overturning the container, or pouring too much water.
