Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.
[0020] The invention discloses a toy polygraph, such as Figure 1 to Figure 4 As shown, it includes a housing 1, a circuit board 2 and a battery. The circuit board 2 is provided with a signal receiving circuit, an analysis circuit, a signal output circuit and an analysis switch that cooperates with the analysis circuit. When the signal receiving circuit receives When at least two groups of signals change, the analysis circuit controls the output current of the signal output circuit; the toy polygraph also includes a signal lamp 3 connected to the signal output circuit. In the present invention, because the signal lamp 3 of the toy polygraph is connected with the circuit board 2 through wires, when the circuit board 2 generates electric current and forms an electric shock, the signal lamp 3 lights up, thereby reminding the user that the signal ...
