In order to more clearly illustrate embodiments of the present invention or technical solutions in the prior art, specific embodiments of the present invention will be described below with reference to the accompanying drawings. It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be obtained from these drawings without inventive effort.
For the sake of simplicity, only the parts relevant to the present invention are schematically shown in the drawings, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled. In this document, "one" means not only "only one" but also a case of "more than one".
An embodiment of the present invention, as shown in fig. 1, is a charging circuit capable of generating negative ions, including:

the voltage transformation module 300 is configured to perform voltage reduction processing on the filtered dc voltage to output an adapter charging voltage, and perform voltage boosting processing on the filtered dc voltage to output a dc negative high voltage to generate negative ions;
and the USB charging interface 400 is used for providing the adapter charging voltage for the connected device to be charged for charging.
Specifically, a substance is composed of molecules, which in turn are composed of atoms, which are composed of nuclei (including protons and neutrons) and electrons, which move rotationally around the nuclei. In the usual case, the negative charge of an electron and the positive charge of a proton are equal, balancing the total charge of an atom to zero. Under the action of external energy, when the movement speed of electrons in the outer layer of the atom is accelerated to a certain degree, the electrons can escape from the orbit to be combined with other neutral atoms, and the negative charge quantity of the atom is increased after the electron is captured, so that the atom has negative polarity, namely negative ions. The bridge rectifier module 100, the filter module 200, the voltage transformation module 300 and the USB charging interface 400 are sequentially connected.
The bridge rectifier module 100 includes a full bridge and a half bridge, the full bridge is formed by packaging four diodes in a bridge rectifier, and the half bridge is formed by packaging two diodes in a bridge rectifier. The setting is carried out according to the working voltage of the charging circuit which can generate negative ions and the requirement of a user.
The filtering module 200 filters the residual ac signal of the dc voltage output by the bridge rectifier module 100, so as to prevent interference to subsequent modules.
One part of the voltage transformation module 300 performs voltage reduction processing on the filtered direct current voltage to output adapter charging voltage, and the other part of the voltage transformation module 300 performs voltage boosting processing on the filtered direct current voltage to output direct current negative high voltage to generate negative ions. Because one part of the voltage transformation module 300 boosts the filtered direct-current voltage to output direct-current negative high voltage, along with the increase of the voltage, the electric field force is increased, the kinetic energy of atoms is increased, a large number of atoms get rid of the gravitational force of atomic nuclei to escape from the orbit, a large number of ions are generated in the mixed gas, meanwhile, the speed of the positive ions and the negative ions moving to the two poles is increased, and the kinetic energy generated by the positive ions and the negative ions is easy to break the neutral molecules, so that the neutral molecules are separated into the positive ions and the negative ions.
