Technical Field
[0001] The utility model relates to the field of power adapter manufacturing, in particular to a circuit for reducing static voltage. Background Art
[0002] The negative ion module attached to the air purifier generates a high static voltage of up to tens of kilovolts when working. This voltage enters the power adapter through other circuits and the power adapter output line, damaging its internal electronic components and causing the power adapter to be damaged and have no output. In order to reduce the damage of this static voltage to electronic components, the conventional method is to add a discharge needle between the primary and secondary of the power adapter. This method is effective for occasional static voltage conditions, but is not effective for long-term static voltage generation.

[0018] When used specifically, through the setting of the power adapter 1 and the resistor 2, this circuit is composed of two resistors 2 connected across the primary and secondary of the power adapter 1. Therefore, the current enters from the input end of the power adapter 1, and after being rectified at the rectifier end of the power adapter 1, it is divided into two parts, one part flows into the two resistors 2 connected across, and the other part flows into the transformer inside the power adapter 1. The two parts meet at the output end of the power adapter 1 and output current from the output end of the power adapter 1. Therefore, after the primary and secondary of the power adapter 1 are connected across the two resistors 2, the primary is connected to the positive end of the electrolytic capacitor after rectification, and the secondary is connected to the negative end of the output. After the electrostatic voltage enters the power adapter 1 through the output line of the power adapter 1, it is stepped down to more than 100 volts through the jumper resistor, thereby simply and effectively reducing the electrostatic voltage and protecting the power adapter 1 line from damage.
[0019] In this embodiment, the power adapter 1 includes a USB interface layer 101, an AC interface layer 102, a base 103 and a power cord 104. The USB interface layer 101 is located at the top of the power adapter 1, the AC interface layer 102 is located in the middle of the power adapter 1, and the base 103 is located at the bottom of the power adapter 1. The outer surface of the USB interface layer 101 is provided with a USB-A interface and a USB-C interface. The number of USB-A interfaces is three, and the number of USB-C interfaces is two. The AC interface layer 102 is in the shape of a three-layer disc, and the outer surface of the disc is provided with an AC interface. The number of AC interfaces on each layer of the disc is five.
[0020] During specific use, through the settings of the USB interface layer 101, the AC interface layer 012, the base 103 and the power cord 104, the power adapter 1 is composed of four parts: the AC interface part, the USB interface part, the base 103, and the power cord 104. The top layer is the USB interface layer 101, which has three side-plugged USB-A interfaces and two USB-C interfaces. The USB interfaces are distributed in various directions, which can meet the charging needs of a family at the same time.
[0021] Working principle: This circuit is composed of two resistors 2 connected across the primary and secondary of the power adapter 1. Therefore, the current enters from the input end of the power adapter 1, and after being rectified at the rectifier end of the power adapter 1, it is divided into two parts, one part flows into the two resistors 2 connected across, and the other part flows into the transformer inside the power adapter 1. The two parts meet at the output end of the power adapter 1 and output current from the output end of the power adapter 1. Therefore, after the two resistors 2 are connected across the primary and secondary of the power adapter 1, the primary is connected to the positive end of the electrolytic capacitor after rectification, and the secondary is connected to the negative end of the output. After the electrostatic voltage enters the power adapter 1 through the output line of the power adapter 1, it is stepped down to more than 100 volts through the jumper resistor, protecting the power adapter 1 line from damage.
