Abstract

This invention discloses a water-powered aroma-infused windmill pour-over coffee device, comprising a coffee cup body, a water inlet structure, and a windmill structure. The coffee cup body includes a base and a body. The water inlet structure is located on the upper edge of the body and includes an inlet and an outlet. The windmill structure includes a rotating shaft and a plurality of rotating blades connected to the shaft. Each blade has a brewing chamber at its tail end. The outlet is positioned corresponding to the rotating blades. Hot water flows from the outlet to the rotating blades, causing them to rotate due to gravity. The hot water extracts coffee grounds in the brewing chambers to form coffee liquid, which flows into the container space. The rotating blades release coffee aroma through their rotation.

Claims

1. A water-powered aromatherapy windmill pour-over coffee maker, comprising: a coffee cup body, including a cup bottom and a cup body, the cup bottom and the cup body forming a receiving space within the coffee cup body; a water inlet structure disposed on the upper edge of the cup body, the water inlet structure including a water inlet and a water outlet, the water inlet injecting hot water, which flows out from the water outlet; and a windmill structure, including a rotating shaft and a plurality of rotating blades connected to the rotating shaft, the rotating shaft being connected to the side wall of the cup body, each of the plurality of rotating blades having a brewing chamber at its tail end, the brewing chamber including a filter and coffee powder within the filter; wherein... The outlet is positioned corresponding to the plurality of rotating blades. Hot water flows out of the outlet to the plurality of rotating blades. Gravity causes the plurality of rotating blades to rotate. The hot water extracts the coffee powder in the brewing chamber to form a coffee liquid, which flows into the coffee container space. The plurality of rotating blades release a coffee aroma by rotating.

2. The water-powered aroma windmill hand-drip coffee maker as described in claim 1 is further provided with a water pumping structure, which is cylindrical in shape, disposed in the accommodating space and connected to the water injection structure. The water pumping structure is provided with a water inlet at the bottom of the cup to draw out the coffee liquid and send it to the water injection structure, where it flows out again from the water outlet to perform a secondary extraction of the coffee powder and maintain the rotation of the plurality of rotating blades.

3. The water-powered aroma windmill pour-over coffee maker as described in claim 2, wherein the water pumping structure is equipped with a timing device, which closes the water inlet after a predetermined time to stop continuous water pumping and complete coffee brewing.

4. The water-powered aromatherapy windmill pour-over coffee maker as described in claim 1, wherein the shaft is connected to a rotary motor that controls the shaft to rotate so as to drive the rotation of the plurality of rotating blades.

5. The water-powered aromatherapy windmill pour-over coffee maker as described in claim 1, wherein the number of the plurality of rotating blades is 3 to 5.

6. The water-powered aromatherapy windmill pour-over coffee maker as described in claim 1, wherein the plurality of rotating blades are set at an angle parallel to the cup body.

7. The water-powered aromatherapy windmill pour-over coffee maker as described in claim 1, wherein the plurality of rotating blades are set at an angle of 10° to 30°.
