The following is the use process of the present disclosure:
The coffee machine for wirelessly driving a coffee cup holder to rotate is powered, a proper amount of water is added into the water tank 1, the coffee cup 6 is placed into the coffee cup holder 501 on the cup holder 5, then the coffee filter cup 7 is placed on the coffee cup 6, a proper amount of coffee powder is added in the coffee filter cup 7, the “simulated artificial brewing” function key 2093 on the control panel 209 is selected, and the sprinkler head 301 is manually adjusted to a position where the coffee powder on the inclined wall of the coffee filter cup 7 can be covered. “ON” button on the control panel 209 is activated. At this time, the first control circuit in the machine body 2 controls the charging coil 207 under the machine body 2 to power on, and the power receiving coil 5032 on the cup holder 5 corresponding to the charging coil 207 obtains induced voltage. The induced voltage supplies power to the second control circuit on the cup holder 5. The coffee cup detector 5031 on the vertical plate 503 starts to work. The coffee cup detector 5031 detects that the coffee cup 6 has been placed on the coffee cup holder 501 on the cup holder 5. The first control circuit receives the signal that “the coffee cup 6 has been placed” on the second control circuit. At the same time, the coffee filter cup detector 303 on the support 3 detects the coffee filter cup 7 placed on the coffee cup 6, and the first control circuit receives the signal of the coffee filter cup detector 303 that “the coffee filter cup 7 has been placed”. At this time, the water in the water tank 1 enters the heater 205. The first control circuit controls the heating element 2052 in the heater 205 to heat (if it is not detected that there is a coffee cup 6 on the coffee cup holder 501 on the cup holder 5 and a coffee filter cup 7 is placed on the coffee cup 6, the heater 205 at the bottom of the machine body 2 does not heat). A temperature sensor 2054 in the heater 205 starts to detect the water temperature. When the temperature sensor 2054 in the heater 205 detects that the water temperature is above 98 degrees, the first control circuit sends a control signal controlling the motor 505 to rotate to the second control circuit through Bluetooth. The second control circuit receives the signal from the first control circuit to control the rotation of the motor 505. The second control circuit controls the motor driving circuit to drive the motor 505 to rotate. The cup holder 501 rotates with the coffee cup 6 driven by the driving motor 505, and the coffee filter cup 7 on the coffee cup 6 also rotates. The first control circuit controls the water pump 203 to start working, pumping boiled water to the water outlet pipe 2051 and entering the first water pipe 204. After passing through the water pump 203, boiled water enters the second water pipe 202 through the water outlet pipe 2031, and then passes through the support 3, pumping boiled water to the sprinkler head 301. Boiled water is sprayed from the water spray nozzle 3011 below the water spray head 301 on the coffee powder on the coffee filter cup 7. At the same time, the rotation of the cup holder 501 rotates the coffee cup 6, and the rotation of the coffee cup 6 rotates the coffee filter cup 7. Although the water spray nozzle 3011 does not rotate due to the rotation of the coffee filter cup 7, the boiled water sprayed by the water spray nozzle 301 can be uniformly sprayed on the coffee powder on the coffee filter cup 7 due to the rotation of the coffee filter cup 7. In this way, the effect of “simulating artificial brewing” of coffee is realized, and the brewed coffee has better taste.
According to the present disclosure, the phenomenon can be avoided that the solidification of coffee powder production caused by manual operation affects the brewing effect and the demand of consumers cannot be met. The present disclosure has the advantages of convenient and professional operation, safe use, low cost, strong reliability and the like.
