Detailed ways

The self-charging USB wireless transmitting and receiving device provided by the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1-5, the self-charging USB wireless transmitting and receiving device provided by the utility model includes a main body 1 and a wireless receiving part 2; the inside of the main body 1 is equipped with a wireless transmitter, and a USB Interface 3, main body rechargeable battery 4 and slot 6, wherein the main body rechargeable battery 4 is located in the middle of the main body 1, the USB interface 3 is connected to the outside of the main body rechargeable battery 4, the slot 6 is formed inside one end of the main body 1, and It communicates with the USB interface 3; the wireless receiving part 2 is installed in the slot 6 on the main body 1 in a detachable manner, and a rechargeable battery 5 is installed inside, and one end of the wireless receiving part 2 is installed with a rechargeable battery connected to the rechargeable battery 5. USB plug 7.

The rechargeable battery 4 and the rechargeable battery 5 of the main body are lithium batteries. Since this battery has no memory effect at all, it is very convenient and simple to use. Periodic discharge management means that the battery can be charged directly regardless of the residual voltage. The charging time is naturally shortened, and the service life of the overall equipment can also be guaranteed.

The method of using the self-charging USB wireless transmitting and receiving device provided by the utility model is described as follows: Pull out in the slot 6 of the battery, then connect the USB plug 7 on it to the USB interface of a computer or other equipment, at this moment, the electric energy can be transferred to the rechargeable battery 5 by the computer or other equipment to charge it At the same time, the user can use the main body 1 to perform operations such as turning pages. When the device does not need to be used, the charged wireless receiving part 2 can be inserted into the slot 6 on the main body 1 with the USB plug 7 facing the slot 6 until the USB plug 7 is inserted into the USB port on the main body 1. In the interface 3, at this moment, the electric energy in the rechargeable battery 5 on the wireless receiving part 2 just can be transferred in the rechargeable battery 4 of the main body through the USB plug 7 and the USB interface 3, therefore do not need to replace the battery or special charging time, Thereby improving the working efficiency of the equipment.
