The working principle is as follows: when the invention is used, when the display screen 13 needs to be disinfected, the controller connected with the motor 21 is controlled by control software to work, the motor 21 is a micro forward and reverse rotating motor, at this time, the motor 21 is electrified to operate, the first bevel gear 22 is driven to rotate by the rotation of the motor 21, the first bevel gear 22 is meshed with the second bevel gear 24, the rotation of the first bevel gear 22 further drives the third bevel gear 27 to rotate through the second bevel gear 24, the rotation of the third bevel gear 27 further drives the fourth bevel gear 28 to rotate, so that the first bevel gear 22 and the fourth bevel gear 28 rotate simultaneously, further the rotating cylinders 23 positioned at two sides of the display screen 13 are driven to rotate effectively, the rotating cylinders 23 further drive the screw rods 26 to rotate effectively, the rotation directions of the two screw rods 26 are opposite, and the slide block 31 is driven to move downwards by the rotation of the screw rods 26, and then drive brush roll 17 to move downwards, when slider 31 moves to the position of boss 42 in switch component 4, fixed rod 41 extrudes boss 42, and then make first spring 45 contract, and then make boss 42 drive guide rod 44 to slide, and then make guide rod 44 contact with contact switch 46 and open contact switch 46, make shower nozzle 12 spray disinfectant toward display screen 13, along with the movement of slider 31, after fixed rod 41 separates with boss 42, the contact of guide rod 44 and contact switch 46 also separates, boss 42 resets through the elasticity of first spring 45, contact switch 46 separates with guide rod 44 and closes, and then make shower nozzle 12 close, in this process the contact time of guide rod 44 and contact switch 46 is short, has prevented effectively that disinfectant from being sprayed by shower nozzle 12 too much, after disinfectant sprays, brush roll 17 continues to move downwards, carry on effectual cleaning to display screen 13, simultaneously with the disinfectant that shower nozzle 12 sprayed all with smear on display screen 13, on the one hand disinfect display screen 13, on the other hand also can take away the heat on the display screen 13 through the volatilization of disinfectant.
In the process that the lead screw 26 drives the slider 31 to move downwards, the slider 31 drives the connecting rope 34 to move, and through the guiding effect of the first pulley 32 and the second pulley 33, the slider 31 can pull the clockwork spring inside the spring box a36 through the connecting rope 34, after the clockwork spring inside the spring box a36 is pulled out, the connecting rope 34 can drive the sleeve plate 18 to move upwards through the spring box a36, so that the inner plate 19 is exposed, meanwhile, the heat dissipated from the display screen 13 through the vent holes in the inner plate 19 can be effectively dissipated, when the sleeve plate 18 is not opened, the moisture in the air is effectively prevented from condensing into water drops which are attached to the inside of the shell 1, and the risk of short circuit is further caused.
When the slider 31 moves to the bottom of the screw rod 26, the starting strip 57 at the bottom of the side hole 15 contacts the support plate 51, the support plate 51 drives the brush roller 17 to rotate, when the slider 31 moves to the inside of the accommodating groove 16, the rotation of the brush roller 17 exceeds 45 degrees, two support plates 51 contacting with the starting strip 57 clamp the brush roller 17, the brush roller 17 is prevented from continuing to rotate, the shaft 56 presses down the sliding plate 63 at the same time, the third spring 64 contracts, the fixed column 66 has a part accommodated in the sliding plate 63 at the same time, the sliding column 65 is accommodated in the fixed column 66, the brush roller 17 presses down the door plate 67, when the brush roller 17 presses down the door plate 67 until the brush roller 17 does not contact with the door plate 67, the door plate 67 automatically resets, the accommodating groove 16 is closed, the surface dust falling of the brush roller 17 is effectively prevented, the service life of the brush roller 17 is effectively prolonged, the number of times of replacing the brush roller 17 is reduced, when the slider 31 travels to the bottom below, the motor 21 can rotate reversely, the slider 31 is driven to ascend through the reverse rotation of the motor 21, the slider 31 drives the brush roller 17 to ascend above the starting strip 57, the starting strip 57 is not clamped with the support plate 51 at the moment, the sliding plate 54 applies elastic force to the limiting rod 55 through the elastic force of the second spring 53 acting on the sliding plate 54, the brush roller 17 further rotates with the shaft rod 56, the brush roller 17 rotates for 90 degrees, the brush roller 17 is effectively replaced with the surface, the cleaning surface of the disinfectant on the display screen 13 in the descending process of the slider 31 is prevented from continuing to clean the display screen 13, the cleaning cloth containing water often leaves dirty objects on the display screen 13, the dry cleaning cloth cannot be used, and the cleaning of the display screen 13 is effectively guaranteed.
In the process that the slider 31 rises, barrel b37 can exert a downward force through connecting rope 38 to lagging 18, because there is not the power that slider 31 provided through connecting rope 34, so lagging 18 can descend, and catch inner panel 19 cover, in the in-process that uses display screen 13, the inside that display screen 13 remaining heat can make shell 1 becomes dry, further prevented that moisture in the air from condensing into the inside of drop of water attached to shell 1 because of the great difference in temperature round the clock and night, and then cause the risk of short circuit, the inside drying of shell 1 has been guaranteed again simultaneously, in this process, barrel a36 can accomodate the clockwork spring, barrel b37 also can accomodate connecting rope 38 simultaneously, and make connecting rope 34 reset.
