[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In the present invention, by designing a touch screen of a capacitive and electromagnetic dual-mode information input device, the cleaning mechanism in the device is used to clean the touch screen body. A cleaning agent is injected into the liquid storage tank. When there is too much debris attached to the touch screen body, the cleaning plate is pulled. The cleaning plate will drive the cleaning roller and the drying strip to move to the right along the touch screen body. The cleaning roller in the cleaning plate moving to the right rotates under the action of friction. The rotating cleaning roller will bring the cleaning agent in the liquid storage tank to the touch screen body. The cleaning agent will reduce the adhesion between the debris and the touch screen body. At the same time, the drying strip in the cleaning plate moving to the right will wipe off the debris and the cleaning agent together from the touch screen body, which is convenient for the user to clean the touch screen body at any time, and solves the problem that after the existing touch screen is used for a long time, sweat or dust and other debris are easily attached to its outer wall, and the debris will block the information on the screen and affect the use effect.

[0017] 2. In the present invention, by designing a touch screen of a capacitive and electromagnetic dual-mode information input device, the connecting mechanism in the device is used to install the cleaning plate. When the drying strip at the bottom of the cleaning plate is damaged, the adjusting plate is rotated. The adjusting plate drives the driving gear to rotate through the driving shaft. The rotating driving gear drives the clamping block to rotate through the connecting ring. When the clamping block rotates to both sides of the connecting pin, the clamping block no longer clamps the connecting pin. The cleaning plate is pulled, and the cleaning plate is separated from the touch screen body, and the drying strip at the bottom of the cleaning plate is replaced, which is more convenient for maintaining the cleaning plate.

After the cleaning agent is filled, screw the sealing screw 206 back into the liquid injection sleeve 205. The sealing screw 206 and the sealing ring 211 re-block the liquid injection sleeve 205. Install the touch screen body 1 in a suitable position. When there is too much debris attached to the touch screen body 1, pull the cleaning plate 201. The cleaning plate 201 will drive the cleaning roller 204 and the drying strip 208 to move to the right along the touch screen body 1. The cleaning roller 204 in the cleaning plate 201 moving to the right rotates under the action of friction. The rotating cleaning roller 204 will bring the cleaning agent in the liquid storage tank 202 onto the touch screen body 1. The cleaning agent will reduce the adhesion between the debris and the touch screen body 1. At the same time, the drying strip 208 at the bottom of the cleaning plate 201 moving to the right will wipe off the debris and the cleaning agent together from the touch screen body 1, thus completing the cleaning of the touch screen body 1;
