In one embodiment, as shown in fig. 2, a method for controlling water output is provided, which is described by taking the method as an example for being applied to the processor in fig. 1, and includes the following steps:

s200, receiving an echo signal cluster, wherein echo signals in the echo signal cluster are signals received by an ultrasonic receiving probe after an ultrasonic transmitting probe sends ultrasonic waves.

The ultrasonic wave transmitting probe transmits a beam of ultrasonic wave to a measured object, the ultrasonic wave is reflected by the surface of the measured object, the ultrasonic wave receiving probe receives echo signals reflected by the ultrasonic wave, the ultrasonic wave is transmitted in a beam form, the reflected echo signals are called echo signal clusters, the echo signal clusters comprise a plurality of echo signals, after the ultrasonic wave receiving probe receives the echo signal clusters, the echo signal clusters are transmitted to the processor, and the processor receives the echo signal clusters.

Wherein, the ultrasonic transmitting probe and the ultrasonic receiving probe are the components of the ultrasonic sensor and are positioned at the front end of the ultrasonic sensor, the ultrasonic sensor generally has only one ultrasonic probe which is used for transmitting ultrasonic waves and receiving ultrasonic wave echo transmitted back by an object, because the ultrasonic probe of the ultrasonic sensor transmits the ultrasonic waves through high-frequency vibration, the ultrasonic wave can be interfered by residual vibration caused by the ultrasonic waves in the process of receiving echo signals to generate a detection blind area, the detection distance of the ultrasonic sensor is limited due to the overlarge detection blind area, when the object to be detected is positioned in the detection blind area of the ultrasonic sensor, effective echo signals can not be discriminated, therefore, the ultrasonic transmitting probe transmits the ultrasonic waves, the ultrasonic receiving probe receives the echo signals, and the problem of the detection blind area caused by the overlarge residual vibration of a single ultrasonic probe can be avoided, and the near zone detection effect is good.

S400, determining whether a cup exists on the base or not according to the amplitude and the phase of each echo signal in the echo signal cluster.
