The utility model relates to the technical field of coffee machines, in particular to a coffee
machine with a weighing quantitative control module, which comprises a coffee
machine body, the weighing quantitative control module is arranged on the coffee
machine body, and the weighing quantitative control module comprises an independent support, a weighing platform, a
pressure sensor and a main
control circuit board. The
pressure sensor is electrically connected with the main
control circuit board, the weighing platform and the
pressure sensor are installed at the upper end and the lower end of the independent support respectively, and a waste water
disc assembly is arranged on the weighing platform. According to the utility model, the weighing platform and the pressure sensor are fixed on the independent support, and the waste water
disc assembly is adjusted to be only contacted with the weighing platform instead of being contacted with the base instead of being normally contacted with the base, so that the weighing effect can be achieved no matter whether the waste water
disc assembly is taken away or not; and the whole machine is controlled by the main
control circuit board to finish extraction, so that accurate and quantitative control is achieved, and the manufacturing cost is lower.
