Problems solved by technology

[0002] Nowadays, more and more devices have entered the "wireless" era, but for mobile phones, MP3 and other devices that often need to be plugged in and unplugged, as well as desk lamps, small stereos and other devices that need to be moved frequently, it is troublesome to connect when using electricity, and the length of the connecting wire is limited. This reduces the mobility and ease of use of the device, and repeated plugging and unplugging causes wear and tear, which reduces the reliability and safety of the power supply

Embodiment Construction

[0009] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0010] like figure 1 As shown, the frequency conversion part in the present invention is a self-excited frequency converter (this is a known technology and will not be described in detail). When the voltage is applied to both ends, a self-excited oscillation is formed by the oscillation coil 9 and the triode 10 in the circuit. The circuit converts the input 220V, 50Hz AC into 0-10V, 30-80KHz AC voltage U 1 , transmitted to the transmitting part connected to it.

[0011] like figure 2 As shown, when the high frequency alternating current U 1 When passing through the transmitting coil 7 of the transmitting part, when there is a receiving coil 8 near the transmitting coil 7, an alternating magnetic field is generated around the desktop 6, and t...

Abstract

The invention discloses a novel radio source apparatus, which includes a frequency conversion part, an emanation part and an accept part, wherein the frequency conversion part being a self-exciting frequency transformer connecting with the emanation part, and transforming input AC into high-frequency current and inputting into the emanation part; the emanation part and the accept part transform through electromagnetic induction, and the obtained alternating current forming direct current after passing thought a rectifier, a filtering circuit and a regulation circuit, so as to supply electricity for the electric appliance. The invention realizes wireless transmission of power supply, and wireless power utilization of minitype electric appliance.

Description

technical field [0001] The invention relates to a power supply device, in particular to a novel wireless power supply device. Background technique [0002] Nowadays, more and more devices have entered the "wireless" era, but for mobile phones, MP3 and other devices that often need to be plugged in and unplugged, as well as desk lamps, small stereos and other devices that need to be moved frequently, it is troublesome to connect when using electricity, and the length of the connecting wire is limited. This reduces the mobility and ease of use of the device, and repeated plugging and unplugging causes wear and tear, which reduces the reliability and safety of the power supply. Contents of the invention [0003] The purpose of the present invention is to provide a novel wireless power supply device. [0004] In order to achieve the above purpose, the power supply device provided by the present invention includes a frequency conversion part, a transmitting part and a receivin...
