Description

[Technical field]

[0001] The present invention relates to the technical field of coffee brewing, in particular to a coffee machine with stirring function. [Background technology]

[0002] With the acceleration of work rhythm and the improvement of living standards, people often make coffee to wake up from sleepiness in order to relieve work stress and relieve fatigue. Coffee can promote metabolic function and activate the digestive system, as well as prevent oxidation, protect the heart, strengthen bones, keep the waist and knees healthy, increase appetite, prevent fat accumulation, promote bowel movements, release moisture in the body, promote blood flow, fight off colds, and relieve body constipation. According to a survey, drinking 100-200 mg of caffeine every day is enough to wake up from sleepiness. At present, coffee machines have gradually entered into ordinary households as household electrical appliances, making it not only more convenient to make coffee, but also because coffee machines directly brew coffee with hot water, the coffee powder can be dissolved evenly, allowing you to enjoy the original flavor of coffee and making it taste better.

[0003] In a drip coffee machine, hot water is used to brew the coffee powder in the filter through the upper head that brews the coffee, and the coffee drips into the coffee pot from the coffee liquid outlet at the bottom of the coffee hopper. When the hot water flows through the coffee hopper, it does not pass through all the coffee powder, so it is not possible to brew fragrant coffee.

[0004] Existing coffee machines are equipped with a stirring rod, which rotates to stir ground coffee powder. This method can stir the coffee powder, but it has the following defects. If the rotational force of the stirring rod is too small, the coffee powder cannot be stirred sufficiently, and if the rotational force is too large, the filter paper may be broken through. Therefore, with the method of rotating the stirring rod, it is difficult to quickly and completely dissolve the coffee powder in hot water, and the caffeine and volatile substances in the coffee powder cannot be sufficiently precipitated, resulting in an insufficient coffee concentration and aroma, and a poor quality coffee liquid. There is a need to solve the above problems. Summary of the Invention [Problem to be solved by the invention]
