Coffee extraction device

Abstract

A coffee extraction device comprises at least: a device body, an extraction cup, a water supply module, and a control module. The device body has a housing that can hold a certain amount of water. The top of the device body has a groove and a cover. A container can be placed below the groove. The cover can open or close the groove. The extraction cup can be placed on the groove of the device body. Multiple ribs protruding from the bottom of the extraction cup can hold and support a coffee bag. A narrow groove is provided in the center of the bottom of the extraction cup. The control module is connected to and controls the water supply module, which heats the water in the housing into hot water and delivers it to the extraction cup. The hot water can soak and extract the coffee bag, and then flow out from the drip hole along the narrow groove into the container to form a coffee beverage, thus achieving the purpose of full extraction.

Claims

1. A coffee extraction device, comprising at least: a device body, having at least a housing, a trough, and a cover, the housing being capable of holding a certain amount of water, the trough being located on the top of the device body, the cover being capable of covering the top of the device body to open or close the trough, and a container being placed below the trough; an extraction cup, which can be placed on the trough of the device body and for holding a coffee bag for extraction, the bottom inner side of the extraction cup having a plurality of ribs arranged in a ring, each rib extending from the wall of the extraction cup toward the center of the extraction cup, and each rib being higher at its end on the wall of the extraction cup, the ribs extending toward the center of the extraction cup. The cup body has a lower center end, giving the ribs an inclined structure. These ribs support the coffee bag, allowing the coffee powder inside to concentrate. The bottom center of the extraction cup body has a narrow groove that can be inserted into the groove of the device body. The bottom of the narrow groove has at least one drip hole. A water supply module is located in the device body. This water supply module heats the water in the tank into hot water and has at least one water outlet device located at the top of the device body, which delivers the hot water to the extraction cup body in the groove. A control module is located on the device body and is connected to control the water supply module.

2. The coffee extraction device as claimed in claim 1, wherein the control module includes at least one control switch, the control switch being located on one side of the device body and capable of controlling the water supply module to start or stop.

3. The coffee extraction apparatus as claimed in claim 1, wherein one end of the water outlet device is pivotally connected to the water supply module, and the other end of the water outlet device is disposed opposite to the upper part of the tank.

4. A coffee extraction device, comprising at least: an extraction cup body, which can be placed above a container for holding a coffee bag and for a user to pour hot water; a plurality of ribs arranged in a ring on the inner bottom surface of the extraction cup body, each rib extending from the wall surface of the extraction cup body toward the center of the extraction cup body, with the ends of each rib on the wall surface of the extraction cup body being higher and the ends of each rib toward the center of the extraction cup body being lower, so that each rib has an inclined structure, the ribs can support the coffee bag and concentrate the coffee powder inside the coffee bag; a slot is provided at the center of the bottom of the extraction cup body; at least one drip hole is provided through the bottom of the slot, when the user pours hot water, the hot water can soak and extract the coffee bag on the ribs, and then flow out from the drip hole along the slot into the container to form a coffee beverage.

5. The coffee extraction device as described in claim 1 or 4, wherein the extraction cup body is further provided with at least one handle, which is located on the top outer edge of the extraction cup body for a user to hold.

6. The coffee extraction apparatus as described in claim 1 or 4, wherein the ribs are also provided on the two opposite outer sides of the slot.

7. The coffee extraction apparatus as described in claim 1 or 4, wherein the coffee bag is a drip coffee bag or a tea bag coffee bag.

8. The coffee extraction apparatus as claimed in claim 1 or 4, wherein the coffee packet contains a measured amount of ground coffee powder and a measured amount of instant coffee powder.

9. The coffee extraction apparatus as claimed in claim 8, wherein the ratio of ground coffee powder to instant coffee powder in the coffee packet is one of the following: 10% ground coffee powder to 90% instant coffee powder, 30% ground coffee powder to 70% instant coffee powder, 50% ground coffee powder to 50% instant coffee powder, 70% ground coffee powder to 30% instant coffee powder, or 90% ground coffee powder to 10% instant coffee powder.
