Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and in particular to a grinding and brewing mechanism for a coffee machine. Background Technology

[0002] Coffee is a popular beverage made by grinding roasted coffee beans and brewing them, renowned worldwide for its unique aroma and stimulating effects. Coffee machines are electrical devices specifically designed for making coffee, quickly extracting its essence through heating, pressurization, or dripping. Common types include espresso machines, drip coffee makers, and capsule coffee machines, providing convenient and efficient coffee solutions for modern life.

[0003] A search revealed that patent CN220024766U discloses a grinding and brewing mechanism for a coffee machine. It uses a first motor to drive a rotating rod to rotate, which causes the rotating head to drive the first grinding blade and the first grinding block to grind the coffee beans for the first time. After the first grinding, the second grinding blade and the second grinding block will grind the coffee beans a second time. Because the distance between the second grinding blade and the second grinding block is closer, the coffee beans can be ground more finely and are easier to brew.

[0004] However, the aforementioned mechanism still has the following drawbacks: Firstly, it directly grinds and compresses the coffee beans using the first and second grinding blades, resulting in insufficient grinding fineness and large particle size in the brewed coffee. Secondly, the parts in contact with the coffee beans cannot be quickly disassembled, making cleaning inconvenient after prolonged use. Therefore, this invention addresses these shortcomings by proposing a grinding and brewing mechanism for a coffee machine. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding and brewing mechanism for coffee machines.

[0011] As a further description of the above technical solution: A heating mechanism is installed in the middle of the water injection pipe.

[0012] As a further description of the above technical solution: A valve is installed in the middle of the water injection pipe.

[0013] This utility model has the following beneficial effects: In this invention, a grinding jar, a feeding pipe, a filter cup, a sieving assembly, a motor, a grinding blade, a water tank, and a pump are installed. The motor drives the grinding blade to rotate at high speed inside the grinding jar, crushing and grinding the coffee beans. The ground powder is then sieved by the sieving assembly and falls into the filter cup. Coffee bean particles that do not meet the particle size standard remain on the surface of the sieving assembly and continue to be ground, ensuring a fine grinding degree.

[0014] In this invention, a base, a vertical plate, a top plate, an annular plate, a grinding jar, a feeding pipe, and a filter cup are provided. The grinding jar and the annular plate are connected by threads, and the filter cup and the feeding pipe are also connected by threads. This allows the grinding jar to be unscrewed from the annular plate and the filter cup to be unscrewed from the surface of the feeding pipe. This makes both the grinding jar and the filter cup of the mechanism detachable, which facilitates cleaning of the parts that come into contact with coffee beans. Attached Figure Description
