Liquid crystal display 5 install in the outside of base 3, the internally mounted of base 3 has battery 8 and signal processing circuit board 7, battery 8 is used for supplying power for weighing sensor 4, signal processing circuit board 7 and liquid crystal display 5. The side of the base 3 is also provided with a key 6 for clearing tare weight, when drinks are brewed, the cup cover 2 is in an open state, the weighing sensor 4 can not generate pressure, and the weighing sensor 4 bears the total weight of the cup body 1 and the materials 9 in the cup.

The working principle of the beverage brewing cup is shown in fig. 2, the weight of the cup body 1 and the weight of the materials 9 in the cup body 1 are borne by the weighing sensor 4, before the beverage is brewed, the cup body 1 is empty, only the weight of the cup body 1 borne by the weighing sensor 4 is pressed and kept for more than 3 seconds, the weight of the cup body 1 can be taken as the tare weight to be cleared and memorized, and the operation can be omitted next time. At this moment, various powders and liquids are added into the cup body 1 one by one, and the sensor 4 generates pressure every time different materials are added, and the output signal of the sensor passes through the signal processing circuit board 7 to drive the liquid crystal display screen 5 to display the weight of the materials in the cup body 1. For example: the beverage is prepared by mixing the main material, the auxiliary material A, the auxiliary material B and water, the dead weight of the cup body 1 is removed by the key 6 when the cup is empty in the first step, and the liquid crystal display screen 5 displays 0 g; secondly, adding the main material into the cup body 1 until the liquid crystal display screen 5 displays 8 g, which means that 8 g of the main material is added; thirdly, adding the auxiliary material A into the cup body 1 until the liquid crystal display screen 5 displays 20 g, and actually adding 12 g of the auxiliary material A because 8 g of the main material exists in the cup; fourthly, adding the auxiliary material B into the cup body 1 until the liquid crystal display screen 5 displays 25 g, and actually adding 5 g of the auxiliary material B because 8 g of the main material and 12 g of the auxiliary material A exist in the cup; fifthly, adding water into the cup body 1 until the liquid crystal display screen 5 displays 175 g, and actually adding 150 g of water; then the mixture is stirred evenly and can be drunk, the formula proportion of the materials can be modified according to personal preference, and the operation steps are similar.
