[0034] Current coffee machines rely solely on mechanical rotation of the grinding disc, lacking external force for grinding, resulting in prolonged grinding time and poor grind uniformity. Therefore, if... Figure 1 As shown, the coffee machine described in this application further includes: a grinding chamber 28, a fixed grinding disc 17, an active grinding disc 16, and a second vibration component 30. The grinding chamber 28 is adapted to communicate with the extraction chamber 29, feeding ground coffee powder into the extraction chamber 29. The fixed grinding disc 17 is fixedly disposed within the grinding chamber 28. The active grinding disc 16 is located within the grinding chamber 28, with its surface facing the fixed grinding disc 17, and is adapted to rotate relative to the fixed grinding disc 17. The active grinding disc 16 is located below the fixed grinding disc 17. The second vibration component 30 is disposed in contact with the fixed grinding disc 17, and is adapted to cause the fixed grinding disc 17 to vibrate while the active grinding disc 16 rotates and rubs relative to the fixed grinding disc 17, grinding the coffee beans into coffee powder, so that the coffee beans contact both the fixed grinding disc 17 and the active grinding disc 16. The fixed grinding disc 17 has a channel for coffee beans to enter between the active grinding disc 16 and the fixed grinding disc 17, and two second vibration components 30 are set at opposite positions near the edge of the fixed grinding disc 17. Figure 1 The vertical arrows and downward-sloping arrows inside the grinding chamber 28 indicate the flow direction of the coffee beans.

[0035] like Figure 1As shown, a first power component 5 is provided inside the coffee machine. The first power component 5 is connected to the active grinding disc 16 and is adapted to drive the active grinding disc 16 to rotate. The first power component 5 can be a drive motor.

[0036] Furthermore, such as Figure 1 and Figure 2 As shown, a second electronic sealing switch 18 is provided near the grinding chamber 28 in the coffee powder conveying channel connecting the grinding chamber 28 and the extraction chamber 29. The second electronic sealing switch 18 is signal-connected to the central processing and storage control unit 27. Under the control of the central processing and storage control unit 27, the second electronic sealing switch 18 opens or closes to control the output of coffee powder. A first solenoid valve 6 is provided downstream of the second electronic sealing switch 18 in the coffee powder conveying channel. The first solenoid valve 6 is signal-connected to the central processing and storage control unit 27. Under the control of the central processing and storage control unit 27, the first solenoid valve 6 opens or closes to control the output of coffee powder. A second solenoid valve 7 is provided near the extraction chamber 29 in the coffee powder conveying channel.

[0038] Existing manual or electric coffee machines lack temperature detection during grinding, failing to maintain a constant temperature within the grinding chamber. This leads to high temperatures generated in the coffee beans during grinding due to friction, accelerating oxidation and resulting in a poorer taste, failing to preserve the original flavor of the beans. Therefore, as... Figure 1 and Figure 2As shown, the coffee machine described in this application further includes: a first temperature sensor 13 and a cooling component 21. The first temperature sensor 13 is disposed inside the grinding chamber 28 and is signal-connected to the central processing storage control unit 27; the first temperature sensor 13 is adapted to acquire the temperature inside the grinding chamber 28. The cooling component 21 is connected to the grinding chamber 28 and is signal-connected to the central processing storage control unit 27. The coffee machine is adapted to activate the cooling component 21 to lower the temperature inside the grinding chamber 28 when the temperature inside the grinding chamber 28 is higher than a set temperature. The cooling component 21 can be a semiconductor cooling component to generate cold air. There can be two cooling components 21 disposed opposite each other near the edge of the grinding chamber 28.

[0039] like Figure 1 and Figure 2 As shown, the coffee machine described in this application further includes a blower 31. The blower 31 can be a fan. The blower 31 is disposed in the grinding chamber 28 and is signal-connected to the central processing storage control unit 27. The coffee machine is adapted to operate such that after the coffee beans are ground, the second vibration component 30 vibrates, causing the coffee powder to separate from the fixed grinding disc 17 and the active grinding disc 16. Simultaneously, the blower 31 is activated to blow all the remaining coffee powder in the grinding chamber 28 into the extraction chamber 29. After the coffee beans are ground in the grinding chamber 28, the vibration of the fixed grinding disc 17 causes the coffee powder to detach from the fixed grinding disc 17, and the fan starts running at high speed, blowing all the coffee powder into the extraction chamber 29, making the residual coffee powder in the grinding chamber 28 almost zero. This prevents cross-contamination of flavor due to residual coffee powder from previous brews, ensuring that the taste of each brewed coffee beverage remains essentially consistent. Simultaneously, the cooling component 21 can be disposed behind the fan, and the fan can blow the cold air generated by the cooling component 21 into the grinding chamber 28. Figure 1 The horizontal arrows and the upward-sloping arrows inside the grinding chamber 28 indicate the direction of cold air flow.

The quality grade of the coffee beans within the storage compartment 26 can be obtained by comparing the appearance color, fullness, and uniformity of the coffee beans in the image with the appearance color, fullness, and uniformity of the coffee beans in the image of standard coffee beans.

[0041] Furthermore, such as Figure 1 and Figure 2 As shown, a third electronic sealing switch 19 is provided at the coffee bean conveying channel connecting the grinding chamber 28 and the storage chamber 26.
