INTERDENTAL CLEANING DEVICE

Electrical device for dental cleaning comprising a support body (2) and an electric motor comprising a rotor shaft (31), which rotates around a first rotation axis (X). The device also comprises a dental cleaning group (4), which comprises a interdental brush (6) connected to the rotor shaft (31) in order to be moved by an oscillatory rectilinear motion along a to-and-fro direction (Z) and motion transformation means (5), housed in the support body (2), interposed between the rotor shaft (31) and the interdental brush (6) in order to transform the rotary motion of the electric motor into the oscillatory rectilinear motion of the interdental brush (6). The motion transformation means (5) comprise at least one eccentric device (51), mechanically connected to the rotor shaft (31) and integral in rotation with the latter, and a transmission member (52), engaged with the support body (2) and mechanically connected to the eccentric device (51) and to the interdental brush (6) in order to move the interdental brush (6) along the to-and-fro direction (Z).
