[0002] An electronic display screen is a display device that uses electronic imaging technology to convert electrical signals into visual text, images, and video content. Its core functionality involves controlling the state of electronic light-emitting units to achieve the display. Depending on its size, protection level, and display characteristics, electronic displays are typically used in multiple fields. For example, small and medium-sized screens are mainly used for mobile phones and tablets, while large-sized screens are primarily used for outdoor LED splicing screens in shopping malls and store window advertising screens. In the case of outdoor large screens, which are often located high up and are the visual focal point of their area, dirt and grime can make them appear messy and negatively impact the overall image of the space, thus requiring frequent cleaning.

[0003] Currently, the cleaning of electronic display screens is mostly done manually by hand with a cleaning cloth or a spray bottle, or by using simple wiping devices without automatic liquid supply or wastewater collection functions.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0035] Example 1

[0036] Reference Figure 1-5 This utility model provides a flexible cleaning device for the surface of an electronic display screen, including a water storage tank 1. The water storage tank 1 is equipped with a screen wiping unit 2 for continuous and gentle wiping of the screen. The back of the screen wiping unit 2 is equipped with an adjustment unit 3 for adjusting the wiping angle. The screen wiping unit 2 includes a water pump 26 installed inside the water storage tank 1 for pumping cleaning liquid, a guide pipe 27 installed at the output end of the water pump 26 for spraying cleaning liquid, a housing 21 installed on the outer surface of the guide pipe 27 for fixing, and a flexible wiping roller 23 rotatably connected inside the housing 21 for screen wiping operations. A water supply pipe 25 is fixedly connected to the back of the housing 21 and is fixedly connected to the output end of the water pump 26. A dirt guide cover 22 is fixedly connected to the side of the housing 21 and a drain pipe 24 is fixedly connected to the output end of the dirt guide cover 22.

[0037] The outer shell 21 has openings on both sides, and two wastewater guide covers 22 are fixedly connected to the side openings of the outer shell 21 to collect the wastewater generated during cleaning. The bottom surfaces of the two wastewater guide covers 22 are connected to the drain pipe 24. The guide pipe 27 is connected to the water supply pipe 25, and the water pump 26 can pump the liquid inside the water storage tank 1 into the guide pipe 27.

[0038] In addition, a scraper 210 is fixedly connected to the inside of the side of the outer shell 21. The scraper 210 is in close contact with the side of the bidirectional water spray pipe 211. The output end of the guide pipe 27 is fixedly connected to the bidirectional water spray pipe 211. The bidirectional water spray pipe 211 is fixedly connected to the inside of the outer shell 21. The top of the outer surface of the flexible wiping roller 23 penetrates the top surface of the outer shell 21 and is movably connected to the synchronous belt 29. The other end of the synchronous belt 29 is movably connected to the synchronous gear 28. The synchronous gear 28 is rotatably connected to the top surface of the outer shell 21.

[0039] Two flexible wiping rollers 23 are installed inside the housing 21. Two synchronous gears 28 mesh with each other. With the cooperation of the synchronous gears 28 and the synchronous belt 29, the two flexible wiping rollers 23 can move relative to each other. A bidirectional water spray pipe 211 is set between the two flexible wiping rollers 23. A scraper 210 is close to the side of the flexible wiping roller 23 and can clean the surface of the flexible wiping roller 23 as the flexible wiping roller 23 rotates.

[0040] In this embodiment, the cleaning fluid is pumped by the water pump 26 and fed into the interior of the bidirectional spray pipe 211 through the water supply pipe 25 and the guide pipe 27. The fluid is then sprayed into the interior of the flexible wiping roller 23 through the spray nozzles on both sides of the bidirectional spray pipe 211. At the same time, driven by the rotary motor 212 on the top of the housing 21, the two synchronous gears 28 and the synchronous belt 29 work together to drive the two flexible wiping rollers 23 to move synchronously in opposite directions. With the assistance of the pressure sensor installed inside, the wet flexible wiping roller 23 can wipe the screen surface with appropriate pressure. At the same time, as the flexible wiping roller 23 rotates, the wastewater on the surface can be scraped off by the scraper 210 and collected into the interior of the dirt guide cover 22, ensuring that the contact surface between the flexible wiping roller 23 and the screen is always kept moist and clean, and ensuring that the screen cleaning operation can be completed efficiently.

[0041] Wastewater scraped off by the scraper 210 and collected inside the sludge guide cover 22 will be collected by the drain pipe 24 and transported to a designated location for collection, so as to avoid the wastewater generated during cleaning from polluting the ground and increasing the workload of subsequent work.

[0042] Example 2

[0043] like Figure 1-5As shown, based on Embodiment 1, an adjustment unit 3 is connected to the screen wiping unit 2 to adjust the angle and height of the outer shell 21 of the screen wiping unit 2 relative to the screen to be cleaned. This design improves the way the structure of the wiping unit height and angle can be flexibly adjusted to allow the operator to clean the electronic display screen while standing on the ground in different environments.

[0044] Preferably, the adjustment unit 3 is provided with a slide rod 33 on the back of the housing 21, a hydraulic rod 32 fixedly connected to the top side of the slide rod 33 for adjusting the wiping angle, and a grip rod 36 slidably connected to the bottom of the outer surface of the slider 34 for adjusting the wiping length. The top surface of the hydraulic rod 32 is fixedly connected to a connecting seat 31, the connecting seat 31 is movably connected to the top of the outer surface of the housing 21, and the outer surface of the slide rod 33 is slidably connected to the slider 34.

[0045] The back of the outer casing 21 is provided with a connecting buckle that is compatible with the connecting seat 31 and the adjusting rod 35. The hydraulic rod 32 can be extended and retracted by hydraulic drive and drive the slider 34 to slide along the surface of the sliding rod 33.

[0046] One end of the slider 34 is fixedly connected to the output end of the hydraulic rod 32. An adjusting rod 35 is movably connected to the side of the slider 34.

[0047] The side clamp 37 can retract as the fastening nut 38 rotates on its surface. The side clamp 37 is adapted to the size of the slide bar 33. The side clamp 37, which is retracted by the fastening nut 38, can limit the slide bar 33.

[0048] By adjusting the slide bar 33 to a suitable length and turning the fastening nut 38, the slide bar 33 is limited and clamped by the retracted side clamp 37. At this time, the grip bar 36 and the slide bar 33 cooperate to adjust the screen wiping unit 2 to a suitable height so that the screen surface can be cleaned by the screen wiping unit 2. Furthermore, the position of the slider 34 can be adjusted by the hydraulic rod 32, and the tilt angle of the adjusting rod 35 can be further changed to realize the angle adjustment of the screen wiping unit 2, ensuring that the screen can be cleaned at a suitable angle.

[0049] The working principle of the flexible cleaning device for electronic display screen surfaces based on the above structure is as follows:

[0050] like Figure 1-5As shown, by adjusting the slide bar 33 to a suitable length and turning the fastening nut 38, the slide bar 33 is limited and clamped by the retracted side clamp 37.

Furthermore, the position of the slider 34 can be adjusted by the hydraulic rod 32, and the tilt angle of the adjusting rod 35 can be further changed to realize the angle adjustment of the screen wiping unit 2, ensuring that the screen can be cleaned at a suitable angle.

[0051] Under the pumping of water pump 26, the cleaning solution is input into the interior of bidirectional spray pipe 211 through water supply pipe 25 and guide pipe 27, and sprayed into the interior of flexible wiping roller 23 through the spray nozzles on both sides of bidirectional spray pipe 211. At the same time, driven by the rotary motor 212 on the top of the housing 21, two synchronous gears 28 and synchronous belt 29 work together to drive the two flexible wiping rollers 23 to move synchronously in opposite directions. The wet flexible wiping rollers 23 perform flexible wiping on the screen surface. At the same time, as the flexible wiping rollers 23 rotate, the wastewater on the surface can be scraped off by scraper 210 and collected into the interior of the dirt guide cover 22, ensuring that the contact surface between the flexible wiping rollers 23 and the screen is always kept moist and clean, ensuring that the screen cleaning operation can be completed efficiently.

[0052] Wastewater scraped off by the scraper 210 and collected inside the sludge guide cover 22 will be collected by the drain pipe 24 and transported to a designated location for collection, so as to avoid the wastewater generated during cleaning from polluting the ground and increasing the workload of subsequent work.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
