The application relates to the technical field of plasma detection, in particular to a double-channel ion energy probe based on a magnetic deflection effect. The application provides a double-channel ion energy probe based on a magnetic deflection effect, which comprises an upper permanent magnet plate, a lower permanent magnet plate, a double-channel collimator and a double-channel probe; the double-channel collimator penetrates into a shell; the double-channel collimator comprises a scanning channel and a reference channel; the scanning channel and the reference channel are connected with different values of voltage; the double-channel collimator is used for enabling ions to enter the shell along the channel direction; the upper permanent magnet plate and the lower permanent magnet plate are fixed at the upper and lower ends of the shell respectively so as to form a uniform magnetic field; the double-channel probe is arranged in the shell and comprises a scanning collection probe and a reference collection probe which are respectively coplanar with the scanning channel and the reference channel; and the scanning collection probe and the reference collection probe are respectively connected with different values of voltage. The scheme can provide an ion current probe with high signal-to-noise ratio.

This utility model discloses a wireless charging system with a magnetic core structure. The magnetic core structure is respectively disposed at the transmitting end and the receiving end. The magnetic core structure includes: a first magnetic core and a second magnetic core connected together; there is a height difference and / or spacing between the first magnetic core and the second magnetic core, such that after the coil is wound around the magnetic core structure, the first magnetic core and the second magnetic core generate magnetic fields in opposite directions; in the working state: the first magnetic core located at the transmitting end is opposite to the second magnetic core located at the receiving end, and the two have different working areas; the second magnetic core located at the transmitting end is opposite to the first magnetic core located at the receiving end, and the two have different working areas. Based on the magnetic core structure and wireless charging system of this application, it can provide high anti-misalignment for wireless charging, reduce the "alignment" requirements of the transmitting end and the receiving end, and improve working efficiency and charging convenience.
