With reference to fig. 7, the specific working principle of the wireless charging ring mouse provided by the present invention is explained as follows:

in an initial state, the wireless charging ring mouse is in a shutdown state, when a user wants to use the wireless charging ring mouse, a power key 7-5 in an operation key 7 is pressed, and a corresponding key 6 is pressed, the wireless charging ring mouse enters a working state, if the electric quantity of a button battery 5 can meet requirements, a working indicator lamp 9 is in a green normally-on state, the wireless charging ring mouse can work normally, otherwise, the working indicator lamp 9 is not on, the wireless charging ring mouse needs to be charged through a charging module 4, and any one of a wired mode and a wireless mode can be selected for charging; when the wired charging mode is selected, the wired charging Micro USB interface 4-2 is connected with an external USB power supply for charging, the TP4056 charging chip in the charging circuit 4-1 can be charged in a constant current and constant voltage mode, and the charging is automatically stopped when the charging voltage reaches 4.2V. When wireless charging is selected, the top surface of the ring mouse body 1 can be covered on the surface of the wireless charger, and the wireless charging process can be realized through electromagnetic induction generated by the wireless charging receiving coil 4-3 and the transmitting coil in the wireless charger. In the charging process, the charging indicator lamp 10 is in a red normally-on state, and the charging indicator lamp 10 is not turned on when the charging is completed or in a non-charging state.

When the finger ring mouse is used, a user firstly pulls out the USB wireless receiver 2 inserted on the finger ring mouse body 1 and then is connected with a computer, and then the finger ring mouse body 1 is worn on a forefinger to start operation. The operation can be completed by rotating the hand in the air and pressing a left mouse button 7-1, a right mouse button 7-2, a drag button 7-3 and a precision selection button 7-4 in the operation keys 7 by the thumb, so that the functions of left and right mouse buttons, scrolling and DPI selection are realized.

The specific process is as follows: when the hand rotates in the air, the micro accelerometer module 3-2 in the main control circuit board 3 generates acceleration signals of an X axis and a Y axis through rotation, two axial analog acceleration signals are transmitted to the main control chip 3-1, the main control chip 3-1 performs digital-to-analog conversion and then performs coding according to a wireless module definition format, and finally the codes are transmitted to the USB wireless receiver 2 through the wireless communication module 3-3. The USB wireless receiver 2 converts the codes into mouse displacement and key signals and sends the mouse displacement and the key signals to a computer. When the hand rotates to the right, the pointer on the computer screen moves to the right; when the hand is rotated to the left, the pointer on the computer screen moves to the left; when the hand rotates upwards, the pointer on the computer screen moves upwards; when the hand rotates downwards, the pointer on the computer screen moves downwards; when the pointer moves to a designated position, pressing a left mouse button 7-1 or a right mouse button 7-2 in the operation keys 7 by using a thumb to finish the actions of the left and right mouse buttons; when the drag key 7-3 is pressed and the hand rotates, actions such as window dragging, page scrolling and the like can be completed; pressing the precision selection key 7-4 changes the sensitivity of the mouse movement, and each time the precision selection key 7-4 is clicked, the sensitivity of the mouse movement jumps to the next precision, and the modes of the sequence 1-2-3-1 are changed, and the sensitivity increases with the increase of the number.

When the work is finished, the USB wireless receiver 2 is inserted into the ring mouse body 1, the power supply button 7-5 is pressed again, the wireless charging ring mouse is in a non-working state, and the work indicator lamp 9 is in a non-lighting state, so that the whole operation process is finished.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or replacements made by those skilled in the art within the scope of the present invention also belong to the protection scope of the present invention.
