From the user's point of view, referring to Figure 1-2, the steps to operate this creative automatic brewing coffee machine are to first turn on the power. Next, a water pump is used to pump water into the hot water storage tank 205, and the water injection is stopped after the hot water storage tank 205 reaches a certain water level. Set the temperature controller 105 to set the boiling water temperature and control the heater (heating unit) 213 to boil the water. When the hot water storage tank 205 reaches the set water temperature, place the coffee cup group 117 to be brewed on the rotatable receiving tray 119, Then the microcontroller 230 is started to input the program (including the setting of control parameters such as linear and rotary motors, water outlet flow, time, etc.). Then you can start the one-button automatic brewing program, as shown in Figure 4, press the start button (step 401), then the microcontroller runs the program (step 403), and synchronously performs the following actions: An output terminal controls the operation of the rotary motor (step 405), and the operation of the outlet head is controlled by the linear motor interface of the microcontroller (step 407), And the second output terminal of the microcontroller reads the flow signal output by the flowmeter to control and control the opening and closing action of the solenoid valve of the water outlet pipe to control the water output of the water outlet (step 409). In a preferred embodiment, the linear motor drives the water outlet to move linearly at a linear rate of about 0.5cm/s~1.0cm/s; the rotation speed of the rotating motor is about 5rpm~10rpm to drive the coffee cup to rotate; through the linear reciprocating Sports water supply, with rotating coffee cup, to simulate the action of hand brewing coffee. The above parameters can be fully simulated by the creators through repeated experiments and deliberately to simulate the human-like brewing feel, thus shaping a brewing machine with artificial intelligence. The prior art completely does not consider the relative movement between the linear movement of the spout and the rotating coffee cup, nor the parameters of the spout, such as flow rate, flow rate, temperature, etc.; therefore, it is completely impossible to achieve the unpredictable effect of this creation that simulates the brewing of the hand feeling and imitation. The advantages. In addition, the above-mentioned temperature, flow rate, and flow rate can be controlled by a microcontroller based on different flavored coffee parameters, and this microcontroller has a built-in coffee flavor control program that has been programmed and stored, and can be changed according to different coffee flavors. Output parameters.

The built-in program described in Figure 4 using the microcontroller design and planning can be modified according to different coffees. In short, the specific flow control is the most critical one. Figure 5 depicts how to adjust the flow control parameters. First, start the flow control key (step 501), then the microcontroller opens the second solenoid valve in the water outlet line, and the flowmeter coupled to the second solenoid valve starts to calculate the flow rate. (Step 503), then start the linear motor to move the water outlet to the correct position (Step 505), determine whether the flow value is higher than a threshold (Step 507), if the condition is met, manually adjust the throttle valve (Step 509) and then return Go to step 507; if the condition is not satisfied, determine whether the flow value reaches the set value after a period of time (step 511), stop when the flow value reaches the set value after a period of time (step 513), otherwise return to step 507.
