Dutch coffee extraction device for extracting the Dutch coffee is combined with the water storage unit for storing water, the bottom of the water storage unit, the discharge control unit for controlling the amount of water sales, and the powder that is stored at the bottom of the water storage unit to store the coffee powder The storage unit and the bottom of the powder storage unit may be made of a coffee storage unit for storing the extracted coffee. (See Figure 1)

However, the conventional Dutch coffee extracting device has a structure in which the discharge control unit is coupled to the bottom center of the water storage unit, and in order to control the discharge amount during the extraction of the Dutch coffee, the coffee storage unit and the water storage unit have to be separated, and then the discharge rate has to be adjusted. have. In addition, the user adjusts the amount of water drip by turning the discharge control unit by hand. Since the water drops and the discharge control unit contacts and falls, the foreign matter or E. coli held in the hand may be mixed in the coffee extract liquid. have.

Therefore, there is a need for a coffee extraction device that is easy to control the discharge amount during the extraction of coffee, and improved hygiene problems.
