The specific embodiment
Below in conjunction with instance and accompanying drawing a kind of even magnetic stimulation of muscle inducible system of the present invention is made detailed description.
As shown in Figure 1, a kind of even magnetic stimulation of muscle inducible system of the present invention includes 220V power frequency supply (1), is responsible for circuit electric energy is provided; Intelligently connecting or disconnecting switch (2) is used with power controller (5), adjusts the input power size as requested; A rectification circuit (3) obtains electric energy from 220V power frequency supply (1), to accumulator (4) power supply, supplies power to power controller (5) and circuit downstream on the other hand on the one hand; Control circuit (6) comprises induction antenna (61), single-chip microcomputer (62) and control output circuit (63), and the three is responsible for control triggering electric circuit (7), the trigger impulse that its output is required; Pulse generating circuit (8) is started working according to the trigger impulse forward position, exports corresponding repetition pulse, and supplies with magnetic stimulation terminal (9) and carry out magnetic stimulation treatment.
