FIELD: individual supplies. ^ SUBSTANCE: ultrasonic device comprises vibrator having vibration element for generation of ultrasonic oscillations, and receiver facing vibrator in order to send ultrasonic oscillations onto hair lock clamped between vibrator and receiver. Vibration element is arranged in the form of longitudinal plate. Resonant points are arranged in the form of periodic lattice on vibration surface, which vibrates in direction of vibration element thickness. On vibrator surface, which faces receiver, or on surface of receiver, which faces vibrator, there are grooves arranged to retain hair care agent. Grooves are arranged so that they contain points, which correspond to resonant points of vibration element. ^ EFFECT: efficient and even absorption of hair care agent, reduced time of treatment and device power consumption. ^ 8 cl, 8 dwg |
