Parameter adjusting method, device and equipment and coffee machine

According to the parameter adjustment method, device and equipment and the coffee machine, the corresponding relation between the time of the extraction period of the coffee machine and the weight of the extracted coffee is obtained, and the extraction pressure of each time point in the pressure curve is adjusted based on the corresponding relation; therefore, the cup outlet speed of the coffee machine is relatively uniform and stable as far as possible by the pressure curve when the coffee with the preset weight is extracted next time, so that the taste of the extracted coffee is improved. 本申请提供的一种参数调整方法、装置、设备及咖啡机，通过获取咖啡机本次萃取期间的时间与萃取咖啡重量之间的对应关系，基于对应关系调整压力曲线中各个时间点的萃取压力，使得下一次萃取预设重量的咖啡时的压力曲线尽可能使得咖啡机的出杯速度相对均匀稳定，从而提升萃取的咖啡的口感。
