Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.
[0021] The invention discloses a toy polygraph, such as Figure 1 to Figure 4 As shown, it includes a housing 1, a circuit board 3 and a battery 4. The circuit board 3 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 the at least two groups of signals change, the analysis circuit controls the signal output circuit to output current; the casing 1 is provided with a battery compartment for placing the battery 4, and the opening of the battery compartment is located on the outer surface of the casing 1 , the toy polygraph also includes a detachable battery cover 2 that closes the opening. In the present invention, because the housing 1 of the toy polygraph is provided with a battery compartmen...

The invention discloses a toy lie detector. The toy lie detector comprises a case, a circuit board and a battery. The circuit board is provided with a signal receiving circuit, an analysis circuit, a signal output circuit and an analysis switch matched with the analysis circuit. When two or more groups of signals received by the signal receiving circuit change, the analysis circuit controls the signal output circuit to output currents. The case is provided with a battery bin used for containing the battery, and the opening of the battery bin is located in the outer surface of the case. The toy lie detector further comprises a detachable battery cover closing the opening. According to the toy lie detector, due to the facts that the case is provided with the battery bin used for containing the battery and the battery cover closing the opening of the battery bin, the opening of the battery bin is located in the outer surface of the case and the battery cover is detachably fixed to the case, the battery cover can be detached conveniently, and the battery is convenient to replace.
Description
technical field [0001] The invention relates to the field of toys, and more specifically, relates to a toy polygraph. Background technique [0002] I have designed a toy polygraph, including a shell, a circuit board and a battery. The circuit board 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 the at least two groups of signals change, the analysis circuit controls the signal output circuit to output a slight current to generate an electric shock. When using, the user first inputs the initial signal through the signal receiving circuit, presses the analysis switch, and then inputs other signals to compare with the initial signal. When the two sets of signals change, the circuit board outputs current to shock the user, thereby reminding the user whether he is lying or not. . This program is unpublished. The inside of ...
