Flow speed adjusting method of beverage machine

The invention discloses a flow speed adjusting method of a beverage machine. The flow speed adjusting method comprises the following steps: detecting a real-time period time value T real of flowmeter-output pulses; judging a period time range Tmin-Tmax of the flowmeter-output pulses corresponding to the period time value T real of the real-time flow pulses; judging whether a current brewing flow speedQ real is within a flow speed range Qmin-Qmax required by the beverage or not according to the Tmin-Tmax; if so, continuously brewing the beverage at the current flow speed; and if not, adjusting the power of a water pump of the beverage machine. Compared with the prior art, the flow speed adjusting method of the beverage machine has the advantages that: on the basis of hardware of existing beverage machines, by means of the flowmeter,the current flow speed is judged by detecting the period time value of the real-time flow pulses output by the flowmeter under the condition that the cost is not increased, and the
