SUPPLY MECHANISM AND SUPPLY DEVICE Russian patent published in 2015 - IPC A47K5/12 

FIELD: machine building.

SUBSTANCE: supply mechanism (4) with liquid tank (10) is suggested, it contains flexible supply section (12) the supply device (2). The supply mechanism (4) contains the first lever (18) located with possibility of rotation around the first rotation axis (28), and the second lever (20) located with possibility of rotation around the second rotation axis (30) and containing the user controlled section (22). The first lever (18) contains the first sliding surface (24), and the second lever (20) contains the second sliding surface (26). The first and the second sliding surfaces (24, 26) are in slide abutment to each other at their joint point. The first and the second rotation axes (28, 30) are parallel to each other, and the first plane continues via the first and the second rotating axes. In the inoperative position of the supply mechanism (4) the user controlled section of the second lever (20) and the joint point are located on the first side of the first plane. The first sliding surface (24) at the joint point is convex, and at least the joint point stays on the first side of the first plane, by 2/3 of the supply stroke of the first lever (18).

EFFECT: improved design.
