DEVICE TO MAKE COFFEE, TEA, ETC Russian patent published in 2012 - IPC A47J31/40 A47J31/57 

FIELD: personal use articles.

SUBSTANCE: invention relates to the field of drinks making. The device comprises a body (1) for a water reservoir (2), a filtering agent (3), comprising a filter holder (4) and a lever (5), supported by the body (1) and supporting the filter holder (4), an arrow (10), installed as capable of indicating brewing strength on a strength indication scale, and a point of reference on the strength indication scale. The device additionally comprises a system (20) to control a force for production and indication of the specified quantitative ratio between water quantity in the water reservoir (2) and substance quantity subject to filtration, in the filter holder (4) and for application of the force to the lever (5). At the same time the system (20) of force control comprises a facility (22) of automatic control to develop the above force (21), increasing as the water level increases in the reservoir so that the brewing strength remains independent on water quantity in the reservoir (2), at the same time the value of the above force equals zero, when the arrow (10) is arranged opposite to the point (12) of reference, and is proportional to the water quantity in the reservoir (2), when the arrow is not in the position opposite to the point (12) of reference.

EFFECT: invention makes it possible to detect relative strength of a resulting drink.
