As the cotton brush stretched to its longest state moves horizontally at a uniform speed along the main surface of the display screen, the cotton brush in an extruded state can effectively wipe the dirt on the screen surface, and the wiped dirt will be accelerated into the sewage square tube under the action of airflow. Finally, after the airflow blows along the screen surface and is output along the inner notch of the guide plate, the dirt can be effectively stored inside the sewage square tube, thereby avoiding the problem of secondary pollution of the screen by dirt.

[0018] 3. The present invention sets a screen obstacle-clearing mechanism outside the screen cleaning mechanism. As the cotton brush is stretched to its longest state, the dirt suction tube advances accordingly with the extension of the cotton brush until the cotton brush expands and presses tightly against the screen. The dirt suction box that discharges air to the outside can pass through the dirt suction tube to increase the cleaning power of the cotton brush on the dirt on the display screen. At the same time, the suction-type cleaning can effectively avoid the occurrence of dust. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0022] It is to be understood that these descriptions are illustrative only and are not intended to limit the scope of the invention.

[0023] The following describes an intelligent interactive display screen provided by some embodiments of the present invention in conjunction with the accompanying drawings. Example 1:

[0024] Combine Figures 1 to 13As shown, the present invention provides an intelligent interactive display screen, including a display screen main body 100, a screen bottom fixing mechanism 200 arranged at the bottom of the display screen main body 100, a stabilizing and sliding mechanism 300 arranged outside the screen bottom fixing mechanism 200, a screen cleaning mechanism 400 arranged in the stabilizing and sliding mechanism 300, a recursive mechanism 500 arranged outside the screen cleaning mechanism 400, and a screen obstacle clearing mechanism 600 arranged between the stabilizing and sliding mechanism 300 and the recursive mechanism 500. The screen bottom fixing mechanism 200 is used to provide a sliding platform for effective transverse movement of the display screen main body 100 and facilitate the storage of removed dirt. The stabilizing and sliding mechanism 300 is used to provide a stable support platform for the self-cleaning of the display screen main body 100. The screen cleaning mechanism 400 is used to self-clean and descale the display screen main body 100 after reset. The recursive mechanism 500 is used to provide kinetic energy for the transverse movement of the screen cleaning mechanism 400 and the screen obstacle clearing mechanism 600. The screen obstacle clearing mechanism 600 cooperates with the screen cleaning mechanism 400 to enhance the cleaning efficiency of dirt on the surface of the display screen main body 100.

[0025] The screen bottom fixing mechanism 200 includes a square drainage pipe 210 fixedly mounted on the bottom of the display screen body 100, two guide plates 230 mounted at both ends of the square drainage pipe 210, a guide plate 240 disposed on the front of the square drainage pipe 210, and a first slider 250 mounted at one end of the guide plate 240. A filter tank 220 is provided at the bottom of the sewage square pipe 210; A dirt storage chamber is formed inside the square drain pipe 210, and the dirt storage chamber is connected to the filter tank 220. A semi-cylindrical groove is formed on the top of the square drain pipe 210, and the two ends of the semi-cylindrical groove are connected to the notches on the inner sides of the two guide plates 230, which are used to drain the dirt cleaned from the surface of the display screen body 100. The stabilization and sliding mechanism 300 includes a fixed base 310, a first back plate 330 disposed on the back of the fixed base 310, a back slide rail 350 mounted on the first back plate 330, a compression spring 3501 disposed on the inner side of the back slide rail 350, and a coordinated slide 3105 disposed on the front of the fixed base 310. The screen cleaning mechanism 400 includes a second back plate 420 movably mounted within the back slide rail 350, a movable base 410 disposed outside the second back plate 420, a position-limiting slide 4105 disposed within the movable base 410, a cotton brush 440 disposed within the position-limiting slide 4105, and a dirt suction pipe 430 disposed within the cotton brush 440 and extending through the position-limiting slide 4105. A truss 450 is provided at one end of the dirt suction pipe 430 extending through the cotton brush 440; The back of the second back plate 420 is provided with a foot that penetrates into the interior of the back slide rail 350, and two symmetrically distributed studs are provided on the foot; The reciprocating mechanism 500 includes a chassis 510 disposed on the second back plate 420, a motor 520 disposed within the chassis 510, a screw rod 540 mounted on the motor 520, a propulsion pad 530 disposed outside the screw rod 540, and a U-shaped frame 5301 disposed within the propulsion pad 530, with the other end of the U-shaped frame 5301 mounted within the truss 450, the screw rod 540 disposed outside the screw rod 540, and a third spring 5402 disposed outside the screw rod 540 and bearing pressure between the deflection gear 5401 and the side guard plate 550. The recursive mechanism 500 further includes a side guard plate 550, and the side guard plate 550 is an L-shaped structure as a whole. A slideway is provided inside the side guard plate 550. A sub-slider is provided on the back of the suction box 640, and the sub-slider is adapted to penetrate the slideway inside the side guard plate 550. The top of the screw rod 540 is provided with four plug-in blocks distributed in a cross shape, and the interior of the deflection gear 5401 is provided with plug-in holes adapted to fit the four plug-in blocks.

[0026] When the stabilizing and sliding mechanism 300 and the screen cleaning mechanism 400 are respectively located on both sides of the display screen body 100, the display screen body 100 is in an initial standby state; When the display screen body 100 needs to be activated, the user only needs to stretch the display screen body 100 and the bottom screen fixing mechanism 200 outward until the display screen of the display screen body 100 maintains the maximum gap with the wall. As the display screen body 100 operates, the gap can accelerate the heat dissipation effect of the display screen body 100 during operation; When the display screen body 100 is finished using and the power is turned off, the user needs to push the display screen body 100 toward the wall until the screen bottom fixing mechanism 200 returns to its initial position, and then control the motor 520 to rotate forward. The driven screw 540 will help push the pad 530, the U-shaped frame 5301 and the truss 450 to rise at a uniform speed until the truss 450 drives the dirt suction pipe 430 and the cotton brush 440 to stretch upward to their longest state. After the cotton brush 440 extends from the inner cavity of the limit slide 4105, the expanded cotton brush 440 will fit the screen of the display screen body 100. As the propulsion pad 530 moves to the top of the screw rod 540, the deflection gear 5401 squeezed by the propulsion pad 530 will mesh with the rack plate 370. Finally, the recursive mechanism 500 will drive the screen cleaning mechanism 400 to move horizontally at a uniform speed along the bottom of the rack plate 370. The cotton brush 440 stretched to its longest position and the dirt suction pipe 430 can improve the cleaning efficiency of the dirt on the surface of the display screen body 100. As the dirt on the surface of the display screen main body 100 is cleaned and falls off under the action of the airflow, the screen bottom fixing mechanism 200 located at the bottom of the display screen main body 100 can effectively capture the fallen dirt, and cooperate with the airflow blowing along the surface of the display screen main body 100 to prevent the dirt from causing secondary pollution to the screen of the display screen main body 100. Example 2:

[0027] Combine Figures 1 to 6 As shown, based on Example 1, the stabilization and sliding assistance mechanism 300 further includes a support plate 360 ​​installed on the top of the first back plate 330, a rack plate 370 installed on the top of the support plate 360 ​​and arranged horizontally, a side slide rail 340 installed on the outside of the first back plate 330, a drain pipe 3102 installed on the fixed base 310, a first base 3103 provided on the top of the fixed base 310, a first top seat 3106 provided on the coordination slide 3105, an auxiliary pressure inclined plate 3104 movably installed between the first base 3103 and the first top seat 3106, two first sleeves 3107 installed on the coordination slide 3105, two first limiting rods 3108 provided inside the fixed base 310, two first springs 3109 provided outside the two first limiting rods 3108 and bearing pressure on the inner walls of the two first sleeves 3107, and a load-bearing beam 320 fixedly installed on the bottom of the fixed base 310, and the movable base 410 is located directly above the load-bearing beam 320; A water tank 3101 is provided inside the fixed base 310 , and the water tank 3101 is connected to a drain pipe 3102 ; The first slider 250 is movably mounted in the sideways slide rail 340; One end of the compression spring 3501 is fixed to the foot, and the other end of the compression spring 3501 is fixed to the inner wall of the back slide rail 350; The interior of the load-bearing beam 320 is provided with a plurality of evenly distributed oval notches.

[0028] Preferably, the load-bearing beam 320 is fixed to the wall by expansion bolts, and the expansion bolts are passed through the oval notches. By adjusting the spacing of the expansion bolts in the oval notches, the stability of the load-bearing beam 320 after fixation is enhanced. The top surface of the fixed base 310 is provided with a hole, and the hole on the top surface of the fixed base 310 is connected to the water tank 3101, and the hole is connected to the filter tank 220; Specifically, when the screen bottom fixing mechanism 200 and the display screen main body 100 are pressurized and move outward laterally, the outer inclined surface of the guide plate 240 will move outward along the auxiliary pressure inclined plate 3104, and finally the auxiliary pressure inclined plate 3104 will be compressed by the guide plate 240 and squeeze the coordination slide 3105 downward until the end faces of the auxiliary pressure inclined plate 3104, the coordination slide 3105 and the top of the fixed base 310 are level. At this time, the leveled auxiliary pressure inclined plate 3104, the coordination slide 3105 and the top surface of the fixed base 310 can provide sufficient and effective support force for the screen bottom fixing mechanism 200 as a whole, thereby ensuring the stability of the display screen main body 100 during activation after extending outward. Example 3:

[0029] Combine Figures 4 to 13 As shown, on the basis of Example 1, the screen cleaning mechanism 400 further includes a pre-pressing plate 4201 arranged on the outside of the second back plate 420, a positioning plate 4101 arranged on the outside of the movable base 410, a screw 4202 movably installed in the pre-pressing plate 4201 and penetrating into the positioning plate 4101, a second base 4102 arranged on the movable base 410, a second top seat 4104 arranged on the limiting slide 4105, a pressure inclined plate 4103 movably installed on the second base 4102 and the second top seat 4104, two second sleeves 4106 installed on the limiting slide 4105, two second limiting rods 4107 arranged inside the movable base 410, and two second springs 4108 arranged outside the two second limiting rods 4107 and bearing pressure on the inner walls of the two second sleeves 4106; A transverse groove is formed at the bottom of the limiting slide 4105, and a guide member 460 is installed at the bottom of the movable base 410, and the guide member 460 is adapted to penetrate into the transverse groove; The outer side of the guide member 460 is provided with an annular groove adapted to guide the dirt suction pipe 430 to extend freely, and the bottom of the guide member 460 is provided with two symmetrically distributed clamping members 470; The screen obstruction removal mechanism 600 includes a main vertical rail 610 disposed outside the second back plate 420, a foot 6201 movably mounted within the main vertical rail 610, a secondary vertical rail 620 mounted on the foot 6201, a dirt suction box 640 disposed on top of the secondary vertical rail 620, and a fourth spring 630 disposed inside the main vertical rail 610 and bearing pressure between the secondary vertical rail 620 and the second back plate 420. The other end of the dirt suction pipe 430 is mounted on the dirt suction box 640; A plurality of evenly distributed slots are formed on one side of the dirt suction pipe 430 facing the display screen body 100 .

[0030] Preferably, the alignment of the filter trough 220 and the top hole of the fixed base 310 can be achieved by a screw 4202. When the screw 4202 is rotated, the distance between the second back plate 420, the back slide rail 350, and the first back plate 330 and the movable base 410 and the fixed base 310 is controlled until the filter trough 220 is accurately aligned with the top hole of the fixed base 310 after reset. The cotton brush 440 has dense air holes inside, and the bottom end of the cotton brush 440 is fixed to the bottom of the inner cavity of the limiting slide 4105, while the top end of the cotton brush 440 is fixed to the truss 450; Specifically, after the upwardly extended cotton brush 440 cleans the dirt on the surface of the display screen main body 100, the reversely pressurized cotton brush 440 will descend at a uniform speed along the display screen main body 100, and finally the cotton brush 440 will shrink into the inner cavity of the limiting slide 4105 along the inclined pressure-bearing inclined plate 4103. At the same time, the deflection gear 5401 that loses pressure will disengage from the rack plate 370, and finally the compression spring 3501 will push the second back plate 420 to quickly return to its initial position.

[0031] The working principle and usage process of the present invention: Depending on the usage mode, the stabilization and sliding mechanism 300 can be directly fixed to the wall with bolts. In addition, a recessed rectangular groove can be opened on the wall, and the device can be placed in the rectangular groove of the wall. After the device is fixed, as the display screen main body 100 is activated, the display screen main body 100 and the screen bottom fixing mechanism 200 are stretched outward as a whole in advance. At this time, the combined sewage discharge square pipe 210 and the guide plate 240 will move laterally outward along the inclined surfaces of the auxiliary pressure inclined plate 3104 and the pressure-bearing inclined plate 4103, and the coordinated slide 3105 and the limiting slide 4105 under pressure will drop downward until the top ends of the coordinated slide 3105 and the limiting slide 4105 are respectively flush with the top ends of the fixed base 310 and the movable base 410, and the first slider 250 will slide stably outward along the lateral slide rail 340. At this time, the display screen of the display screen main body 100 will maintain a certain distance from the wall to improve the heat dissipation efficiency of the display screen main body 100 during operation. The display screen main body 100 is an interactive operating system, so the user can directly touch the screen of the display screen main body 100. When the display screen main body 100 is used up and the power is turned off, the display screen main body 100 needs to be pushed inward until the display screen main body 100 is reset. Then, the motor 520 is controlled to rotate forward. As the transmission shaft in the motor 520 drives the screw rod 540 to rotate, the propulsion pad 530, the U-shaped frame 5301 and the truss 450 are subjected to the lifting force of the booster, and the truss 450 drives the dirt suction pipe 430 and the compressed cotton brush 440 to extend outward. As the cotton brush 440 continues to stretch until it reaches the same height as the screen of the display main body 100, the cotton brush 440 will eventually expand and fit onto the screen of the display main body 100, and after the propulsion pad 530 rises to the top of the screw rod 540, it is restricted by the side guard plate 550. The propulsion pad 530 at the highest position will rotate while maintaining its highest state. The deflection gear 5401 is squeezed by the propulsion pad 530 and is engaged with the plug at the top of the screw rod 540. Finally, the deflection gear 5401 compresses the third spring 5402 and engages with the teeth at the bottom of the rack plate 370. As the deflection gear 5401 continues to rotate, the recursive mechanism 500 as a whole will drive the screen cleaning mechanism 400 to slide laterally along the display screen body 100. The expanded cotton brush 440 can effectively clean fingerprints, dirt and water stains on the screen of the display screen body 100. At the same time, as the dirt suction box 640 discharges air, the dirt suction pipe 430 with multiple slots cooperates with the cotton brush 440 to release air outward, and the dirt actively attracted by the cotton brush 440 will be absorbed faster. As the cotton brush 440 moves to the other end of the display screen body 100 and the movable base 410 is fitted with the fixed base 310, the motor 520 can be controlled to reverse, and the deflection gear 5401 that has lost pressure will be squeezed downward by the third spring 5402 and will quickly adapt to the threaded section of the screw rod 540, eventually pushing the pad 530, the U-shaped frame 5301 and the truss 450 to descend rapidly, and the cotton brush 440 squeezed by the truss 450 will be re-compressed into the inner cavity of the limiting slide 4105, and after the deflection gear 5401 is disengaged from the rack plate 370, the compression spring 3501 that has lost pressure will push the second back plate 420 to quickly reset, and eventually the screen cleaning mechanism 400 and the recursive mechanism 500 will return to their initial positions.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
