本发明公开一种液体加热器及其基于液量估计的智能加热控制方法。智能加热控制方法包括步骤：确定液体加热的目标温度t0，获取液体的初始温度t1，以预设的第一加热功率P1开始加热；以第一加热功率P1持续加热时长T后，获取所述加热容器内的液体的温升△t，估计液体的液量；根据估计得到的所述液量，通过查找预先建立的液量-温度补偿-功率三者的映射表确定出温度补偿值t2和第二加热功率P2；以目标温度t0减去温度补偿值t2确定温度阈值，以第一加热功率P1将液体持续加热达到温度阈值时，以第二加热功率P2继续加热至目标温度t0，P2＜P1。本发明兼顾了加热速度及避免发生快速加热产生剧烈沸腾从而获得较佳的加热效果。 The invention discloses a liquid heater and an intelligent heating control method thereof based on liquid amount estimation. The intelligent heating control method comprises the steps that the target temperature t0 of liquid heating is determined, the initial temperature t1 of liquid is obtained, and heating is started at the preset first heating power P1; after continuous heating is conducted for the duration T at the first heating power P1, the temperature rise deltat of the liquid in the heating container is obtained, and the liquid amount of the liquid is estimated; according to the estimated liquid amount, a temperature compensation value t2 and second heating power P2 are determined by searching a pre-establis
