Thermostatic mixer with single control lever

A thermostatic mixer (100, 101) comprising:

• a body (25) having a longitudinal axis (X-X);
• manually adjusting means (D) to adjust the inflow rates of hot water (H) and cold water (C) in the mixer (100, 101), operable by a user,
• automatic adjusting means (13-15, 17-18, 20, 21) to adjust the temperature of the mixed water (M) delivered by the mixer (100, 101), adjustable by the user,
• a single control lever (2, 102) rotatable by the user on a vertical plane parallel to the longitudinal axis (X-X), or containing such axis (X-X), to control the manually adjusting means (D) of the inflow rates of hot water (H) and cold water (C), and rotatable by the user on a horizontal plane orthogonal to the longitudinal axis (X-X) to control the automatic adjusting means (13-15, 17-18, 20, 21) of the temperature of the mixed water (M),
• a gear mechanism (200) functionally interposed between the control lever (2, 102) and the automatic adjusting means (13-15, 17-18, 20, 21) of the temperature of the mixed water (M), wherein the gear mechanism (200) defines a gear ratio different from 1:1.
