Wireless device with charging function

Abstract

The invention relates to a wireless device with the charging function, which comprises a power supply generating device, a rectifier circuit, a comparator circuit, a switching circuit and a charging battery, wherein the power supply generating device can convert kinetic energy to electrical energy through the operation of the power supply generating device by a user and provide the electrical energy for the rectifier circuit, the rectifier circuit can rectify the electrical energy provided by the power supply generating device and then output direct current, the comparator circuit can compare a current sampled voltage of the charging battery with a preset voltage of the comparator circuit, the switching circuit is connected to control the direct current to charge the charging battery if the current sampled voltage is smaller than the preset voltage, and the switching circuit is not connected for controlling the direct current not to charge the charging battery if the current sampled voltage is larger than or equal to the preset voltage. The wireless device with the charging function can conveniently, quickly and automatically charge the wireless device.

Description

technical field [0001] The invention relates to a wireless device with charging function. Background technique [0002] Electronic devices such as mice and radios are common tools in people's daily work and life. Taking the mouse as an example, it is divided into a wired mouse and a wireless mouse. A general wired mouse transmits data and power through a transmission line connected to the computer host, so that the mouse can work normally, but the length of the transmission line of the wired mouse is limited so that the user cannot operate the computer from a long distance, so the wireless mouse came into being, the wireless mouse It is widely used because of its advantages of portability and ease of use. [0003] At present, there are generally two charging methods for wireless mice. One is to use rechargeable batteries or dry batteries. . The other is to use the wireless mouse with auxiliary equipment such as a mouse pad. The mouse pad is connected to the computer host...

Problems solved by technology

[0003] At present, there are generally two charging methods for wireless mice. One is to use rechargeable batteries or dry batteries.

The other is to use the wireless mouse with auxiliary equipment such as a mouse pad. The mouse pad is connected to the computer host to obtain power. The mouse is equipped with a coil that cooperates with the mouse pad. Through the mutual inductance of the coil, the mouse can obtain the required power. But this method also has shortcomings. When using this wireless mouse, its effective range is limited to the surface of the mouse pad that matches it or the limited space of about three centimeters vertically. Otherwise, the wireless mouse cannot work normally.
