[0017] See Figure 1 The double-bean single-brew coffee machine of the utility model comprises a cold water tank 2, a hot water tank 6, a brewer 8, a powder drop funnel 9 and a bean grinding mechanism. The cold water tank 2 has the function of pre-storing water. The hot water tank 6 is used to heat cold water to a set temperature for use in making coffee. The brewer 8 is a device for extracting emulsified coffee. The cold water tank 2 is connected to the hot water tank 6 by a pipeline, and the hot water tank 6 is connected to the brewer 8 by a pipeline. The bean grinding mechanism comprises a first bean grinder 10 for grinding grade A coffee powder and a second bean grinder 11 for grinding grade B coffee powder. The first bean grinder 10 has a grade A coffee bean bin, which contains grade A coffee beans, and the first bean grinder 10 grinds the grade A coffee beans in the grade A coffee bean bin into powder. The second bean grinder 11 has a grade B coffee bean bin, which contains grade B coffee beans, and the second bean grinder 11 grinds the grade B coffee beans in the grade B coffee bean bin into powder. One end of the powder falling funnel 9 is mounted on the bean grinding mechanism, and the other end of the powder falling funnel 9 is plugged into the powder receiving port of the brewer 8. The powder falling funnel 9 is a device that is compatible with the passages of the two bean grinders and guides the coffee powder into the brewer 8.

[0018] The coffee machine further comprises a water inlet valve 1 , which is a device for injecting water into a cold water tank 2 . The cold water tank 2 is connected to an external cold water source via a first water pipe 12 , and the water inlet valve 1 is mounted on the first water pipe 12 .

[0019] The coffee machine further comprises a flow meter 3 , which is used to calculate the flow of incoming water and give a signal to the main board. The cold water tank 2 is connected to the flow meter 3 via a second water delivery pipeline 13 .

[0020] The coffee machine also includes a three-way joint 14, an electromagnetic pump 4 and a pressure relief valve 5. The electromagnetic pump 4 is used to fill the hot water tank 6 with water, and the electromagnetic pump 4 is also the source of water power when extracting coffee. The pressure relief valve 5 is the maximum set pressure of the water system and is used to protect the water system. The flow meter 3 is connected to the first interface of the three-way joint 14 through the third water supply pipeline 15, the electromagnetic pump 4 is connected to the second interface of the three-way joint 14 through the fourth water supply pipeline 16, and the pressure relief valve 5 is installed at the end of the electromagnetic pump 4. One interface of the pressure relief valve 5 is connected to the third interface of the three-way joint 14 through the fifth water supply pipeline 17, and the other interface of the pressure relief valve 5 is connected to the hot water tank 6 through the sixth water supply pipeline 18.

[0021] The coffee machine further includes a coffee valve 7, which is a valve for connecting the hot water tank 6 and the brewing device 8 and for discharging the residual liquid in the pipeline after extraction. The coffee valve 7 is provided with a pressure relief port 71, and the residual liquid in the pipeline after extraction is discharged from the pressure relief port 71. One interface of the coffee valve 7 is connected to the hot water tank 6 through the seventh water delivery pipeline 19, and the other interface of the coffee valve 7 is connected to the brewing device 8 through the eighth water delivery pipeline 20.

[0022] The working principle of the double-bean single-brew coffee machine is as follows: cold water is injected into the cold water tank 2 through the water inlet valve 1, and then through the flow meter 3, the electromagnetic pump 4 is used to inject water into the hot water tank 6 through the command. After the hot water tank 6 is heated, it flows to the brewer 8 through the coffee valve 7. At the same time, the freshly ground coffee powder of the first bean grinder 10 and the second bean grinder 11 enters the brewer 8 to extract the coffee liquid. When the pressure in the water system does not exceed the set pressure of the pressure relief valve 5, the pressure relief valve 5 automatically closes the pressure relief function, and the cold water passes through the first water pipeline 12, the second water pipeline 13, the third water pipeline 15, the fourth water pipeline 16 and the sixth water pipeline 18 in sequence. When the pressure in the water system exceeds the set pressure of the pressure relief valve 5, the pressure relief valve 5 automatically opens the pressure relief function to protect the water system pressure below the set pressure. The cold water is heated by the hot water tank 6 and becomes hot water. The hot water enters the brewer 8 after passing through the seventh water pipe 19 and the eighth water pipe 20. The powder dropping funnel 9 drops the ground grade A coffee powder and the ground grade B coffee powder into the brewer 8. The coffee powder and the hot water are extracted and emulsified into coffee liquid in the brewer 8.

[0023] The double-bean single-brew coffee machine has a very reasonable structural design. By arranging a first bean grinder 10 for grinding grade A coffee powder and a second bean grinder 11 for grinding grade B coffee powder, a powder drop funnel 9 mixes the ground grade A coffee powder and the ground grade B coffee powder together and drops them into a brewer 8, which can meet the customer's need for coffee drinks made from two or different grades of coffee beans and satisfy the customer's personalized needs.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
