Claims

[Scope of utility model registration request]

A discharge bed 1 in which a first mesh plate 16 holding a filter F is mounted on a discharge hole 12, and a cylinder which is separated from the discharge bed 1 when the strip-shaped filter F is moved and receives supply of raw material a and hot water inside. 2
A nozzle 41 is disposed so as to spout hot water into the piston body 31 which is inserted into the cylinder 2 and forms a cavity 312, and is attached to the discharge bed 1 at the opening of the cavity 312. In the extraction section constituted by the piston 3 fitted with the second mesh plate 34 that presses the raw material a between the first mesh plate 16 and the nozzle 41 in the cavity 312 of the piston main body 31.
The umbrella-shaped diffuser plate 38 has an apex 381 at a location facing the nozzle port 411, and the opening diameter of the through holes 382 increases as the distance from the apex increases, or the number of through holes per unit area increases. A beverage extraction mechanism characterized by being attached.
