The utility model provides a groove-shaped induction type charger of an electromechanical device. A control module and a power supply coil module are arranged in a base of a power supply base, and an induction charging receiver and the electromechanical device are accommodated in an accommodating groove on the base; a charging module and a power receiving coil module are arranged in an expansion seat of the induction charging receiver; a butting part for butting with the electromechanical device is arranged on the expansion seat; an induction coil provided with at least two groups of first coils and second coils with different encircling directions is wound on a magnetic conductor of each of the power supply coil module and the power receiving coil module; an induction section formed between the first coils and the second coils are used for generating induction power; and the induction charging receiver can transfer energy by matching with a narrow induction surface needed by the power supply base under the condition that the overall thickness of the electromechanical device is not increased, and can reduce the occupied space. The groove-shaped induction type charger meets requirements on lightness, thinness, shortness and smallness of a product.
