Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and more specifically, to a coffee bean feeding assembly for a coffee machine. Background Technology

[0002] More and more families are using coffee machines. Traditional coffee machines generally use pre-ground coffee to brew coffee, but pre-ground coffee is expensive, which is costly for families who drink coffee regularly. To address this, some people have developed coffee machines with a grinding function. These machines typically use a grinding device to grind coffee beans into powder before brewing. Existing coffee machines have a bean feeder at the bean filling port to ensure a certain amount of coffee beans fall into the machine.

[0003] A search revealed that Chinese utility model patent application number CN201521016073.6 discloses a coffee bean feeding assembly and a coffee machine, including a feeding hopper, a metering component, a bean holding chamber, and a grinding blade. The feeding hopper is used for feeding coffee beans, and the metering component is connected between the feeding hopper and the bean holding chamber. The metering component includes a driving device and a bean holding chamber. The driving device is used to drive the bean holding chamber to move so that the bean holding chamber alternately communicates with the feeding hopper and the bean holding chamber. The grinding blade is located below the bean holding chamber and is used to grind the coffee beans in the bean holding chamber into coffee powder.

[0004] In use, the inner frame is rotated by a drive device. When the lower bean chamber is aligned with the discharge port of the hopper, the upper part of the lower bean chamber is connected to the discharge port of the hopper, while the lower part of the lower bean chamber is closed by the outer frame, allowing coffee beans to be collected in the lower bean chamber. When the lower bean chamber is aligned with the collecting bean chamber, the lower part of the lower bean chamber is connected to the collecting bean chamber through the opening of the outer frame, allowing the coffee beans in the lower bean chamber to fall into the collecting bean chamber. Although the inner frame is equipped with 10ml and 15ml lower bean chambers, it can only meet people's needs for coffee concentration in these two situations, making it inconvenient for people to adjust it according to their own needs in other ranges, resulting in a high degree of limitation in its use.
