The wheel 17 is meshed with the lower gear 18, and a ratchet mechanism 21 is connected to the upper gear 17 and the lower gear 18, and the ratchet mechanism 21 is connected to the rotating rollers 22 at the corresponding upper and lower positions. A water tank 13 is embedded on the rear end surface of the management terminal 10, and a water pipe 14 is connected to the upper end of the water tank 13, and absorbent cotton 25 evenly distributed on the left and right is provided on the front end surface of the water tank 13. A sponge 24 is provided at the lower end of the water pipe 14 and at the rear end of the dust-proof film 23. An elastic support mechanism 26 is connected to the management terminal 10 and at the rear end of the sponge 24, and the elastic support mechanism 26 provides support for the sponge 24. Two water-absorbing sleeves 27 distributed up and down are rotatably connected in the management terminal 10 and at the lower end of the sponge 24. The two water-absorbing sleeves 27 can be tightly attached to the dust-proof film 23, and the rear ends of the two water-absorbing sleeves 27 are abutted with squeezing rollers 28. Drainage grooves 29 are provided in the management terminal 10 and at the two squeezing rollers 28.

[0026] This program has the following working process:

[0027] When in use, the cleaning strip 12 is pushed downward, so that the fixing frame 15 fixedly connected to the cleaning strip 12 pushes the rack 16 to slide downward, and the lower gear 18 is driven to rotate under the meshing of the rack 16 and the lower gear 18, so that the upper gear 17 arranged at the upper end is synchronously driven to rotate under the connection with the rotating mechanism 19, so that the rack 16 meshed with the upper gear 17 moves upward, and the rack 16 drives the fixedly connected baffle 11 to move upward through the fixing frame 15, and the surface of the baffle 11 is cleaned by the cleaning strip 12, and the baffle 11 is opened, so that the display screen 20 at the front end of the management terminal 10 is in contact with the outside world, and the user confirms the plan and performs operation management through the display screen 20, thereby realizing the project management function;

[0028] The rotation of the upper gear 17 is transmitted to the ratchet mechanism 21 through the connection between the upper gear 17, the lower gear 18 and the ratchet mechanism 21, and the upper and lower rotating rollers 22 are driven to rotate synchronously through the setting of the ratchet mechanism 21. For example, when the upper gear 17 rotates forward, the contact between the pawl and the ratchet wheel can drive the transmission rod of the ratchet mechanism 21 to rotate. On the contrary, when the upper gear 17 rotates reversely, the ratchet wheel loses the contact with the pawl, the transmission rod of the ratchet mechanism 21 stops rotating, and the rotating roller 22 remains stationary. Under the synchronous rotation of the two rotating rollers 22, the dustproof film 23 abutting on the outer periphery of the rotating roller 22 is mobilized to move, and the surface is changed in the front and rear directions to keep the dustproof film 23 on the front end surface of the display screen 20 clean.

[0029] The dust-proof film 23 changes its surface front and back under the rotation of the rotating roller 22, and the dust-proof film 23 at the rear end passes through the sponge 24 and the water-absorbing sleeve 27 in turn. At the sponge 24, the water in the water tank 13 can flow into the sponge 24 through the water-absorbing cotton 25 for the sponge 24 to absorb, thereby maintaining the humidity at the sponge 24, and the sponge 24 is kept in contact with the dust-proof film 23 through the elastic support mechanism 26, so that during the circumferential movement of the dust-proof film 23, the dust-proof film 23 that changes its surface front and back is cleaned. During the process of changing the surface front and back of the dust-proof film 23, the dust-proof film 23 then contacts the water-absorbing sleeve 27, driving the water-absorbing sleeve 27 to rotate, and then the water-absorbing sleeve 27 absorbs the liquid remaining on the surface of the dust-proof film 23, and when the water-absorbing sleeve 27 contacts the squeezing roller 28, the water-absorbing sleeve 27 is squeezed, so that the water-absorbing sleeve 27 discharges the absorbed liquid during the circumferential rotation, and the liquid is discharged to the rear end of the management terminal 10 through the drainage groove 29;

[0030] After use, the user pushes the cleaning strip 12 upward to reset the baffle 11 and the cleaning strip 12, and controls the upper gear 17 and the lower gear 18 to rotate under the meshing of the rack 16 and the upper gear 17 and the lower gear 18, and controls the rotating roller 22 to rotate under the connection of the ratchet mechanism 21, so that the dustproof film 23 switches the front and back surfaces, removes dust on the surface of the dustproof film 23 through the sponge 24, and scrubs the surface of the dustproof film 23 to remove dirt;

[0031] The user can remove the elastic support mechanism 26 at the rear end of the management terminal 10 to replace the sponge 24 .

[0032] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
