DEVICE, IN PARTICULAR A DOSING UNIT

摘要

The device is designed in particular as a dosing dispenser (2). It has an integrated electrical consumer unit (30), and a piezoelectric generator (14) for generating a very small amount of energy for energy- autonomous powering of the consumer unit (30). The dosing dispenser (2) moreover has an actuator element (26), which is movable from a starting position to an end position over an actuation stroke (H1), and moreover a control element (18) for mechanical actuation of the generator (14), which control element (18) is movable over a control stroke (H2) from a base position to an end position. Arranged between the actuator element (26) and the generator (14) is a transmission unit (28), which has the control element (18) and which is designed in such a way that the actuation stroke (H1) is decoupled from the control stroke (H2), such that only a limited stroke section of the actuation stroke (H1) is converted to the control stroke (H2). In particular, a first idle stroke (L1) is formed at the start of the actuation. The decoupling preferably takes place with the aid of an eccentric drive that comprises an eccentric unit (24).
