[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1-7A cleaning device for insulated glass windows includes a window frame 1, an insulated glass 32 inside the window frame, a water injection structure 29 at the top of the window frame, and a pull rope lifting structure 30 passing through the top and bottom of the window frame. A first cleaning structure 31 and a second cleaning structure are respectively installed on the window frame on both sides of the insulated glass 32, and the first cleaning structure 31 and the second cleaning structure are connected by the pull rope lifting structure 30 to form a cleaning device for double-sided linkage lifting and cleaning of the insulated glass 32. Cleaning cotton and a squeegee 24 are provided inside both the first cleaning structure 31 and the second cleaning structure.

[0034] The cleaning steps are as follows:

[0035] S1. When the cleaning structure 1 31 is located at the top of the insulating glass 32 facing the indoor side, the cleaning structure 2 is located at the bottom of the insulating glass 32 facing the outdoor side. After injecting cleaning liquid into the water injection structure 29, the water injection structure 29 is installed on the window frame on the indoor side.

[0036] S2, the water injection structure 29 sprays the cleaning liquid on the outdoor side of the insulating glass 32, and at the same time manually sprays the cleaning liquid on the indoor side of the insulating glass 32, pulls the cleaning structure 1 31 downward, and drives the cleaning structure 2 upward through the pull rope lifting structure 30;

[0037] S3. When the cleaning structure 1 31 and the cleaning structure 2 move, the cleaning cotton cooperates with the cleaning liquid to clean both sides of the glass. At the same time, the wiper 24 scrapes off the water stains left on the surface of the insulating glass 32 after the cleaning cotton moves, thereby achieving simultaneous maintenance and cleaning of both sides of the insulating glass 32.

[0038] The insulating glass 32 includes an outer glass 2 and an inner glass 3 bonded to the inside of the window frame 1 by glass glue. A sealing strip 4 is provided on all sides between the outer glass 2 and the inner glass 3. Two sliding grooves 19 are provided on both sides of the inner wall of the window frame 1.

[0039] The first cleaning structure 31 includes a first sliding horizontal plate 12, and the second cleaning structure includes a second sliding horizontal plate 5. The second sliding horizontal plate 5 and the first sliding horizontal plate 12 are slidably connected between the two sliding grooves 19 and on one side of the outer glass 2 and the inner glass 3, respectively. The top and bottom of the window frame 1 are respectively provided with an upper receiving groove 6 and a lower receiving groove 7. Cleaning cotton 18 is provided on the side of the first sliding horizontal plate 12 and the second sliding horizontal plate 5 that are close to each other. The first sliding horizontal plate 12 and the second sliding horizontal plate 5 are connected by a pull rope lifting structure 30.

[0040] The water injection structure 29 includes a water storage box 13 fixedly connected to the inside of the upper storage tank 6, and a water pipe 14 is fixedly connected to the bottom of the water storage box 13 at equal intervals. One end of the water pipe 14 extends to one side of the outer glass 2. One side of the water storage box 13 has a water injection port, and the water injection port extends to the outside of the window frame 1.

[0041] The water storage box 13 has an outward-extending water inlet on one side, making it easy to manually pour water into the water storage box 13. Water is added to the water storage box 13 manually, and the water inside flows through the water pipe 14 to the side of the outer glass 2. Since one end of the water pipe 14 is inclined, the water flowing out will impact the outer glass 2, causing the water to flow along the outer glass 2, and then rinse the inner glass 3 with water.

[0042] The pull rope lifting structure 30 includes an upper connecting rope 11 and a lower connecting rope 10. Upper guide wheels 9 are installed at the four corners of the bottom of the inner wall of the upper containing groove 6, and lower guide wheels 8 are installed at the four corners of the top of the inner wall of the lower containing groove 7. The upper connecting rope 11 is fixedly connected between the first pushing and pulling horizontal plate 12 and one end of the top of the second pushing and pulling horizontal plate 5, and the lower connecting rope 10 is fixedly connected between the first pushing and pulling horizontal plate 12 and one end of the bottom of the second pushing and pulling horizontal plate 5.

[0043] By providing the pull rope lifting structure 30, when the first push-pull horizontal plate 12 is pulled downward, the end of the upper connecting rope 11 connected to the first push-pull horizontal plate 12 moves downward synchronously, and the two upper guide wheels 9 can play a guiding role while reducing wear. The end of the upper connecting rope 11 connected to the second push-pull horizontal plate 5 moves upward, thereby driving the second push-pull horizontal plate 5 to move upward. During this process, the upper connecting rope 11 and the lower connecting rope 10 are always kept in a tensioned state. In this way, when the first push-pull horizontal plate 12 is moved upward, the lower connecting rope 10 is used to drive the second push-pull horizontal plate 5 downward, thereby achieving a reciprocating alternation.

[0044] Manually pull the first push-pull horizontal plate 12 downward to move the cleaning cotton 18 inside, thereby cleaning the inner glass 3. While the first push-pull horizontal plate 12 is moving, the second push-pull horizontal plate 5 is driven upward by the pull rope lifting structure 30. Similarly, the cleaning cotton 18 inside the second push-pull horizontal plate 5 will clean the outer glass 2. When the first push-pull horizontal plate 12 moves to the bottom, the second push-pull horizontal plate 5 will move to the top, and then the first push-pull horizontal plate 12 is pulled upward again. This reciprocating movement drives the first push-pull horizontal plate 12 and the second push-pull horizontal plate 5 to move alternately and perform the cleaning operation. In this way, the outer glass 2 can be cleaned at the same time as the inner glass 3, greatly improving work efficiency while avoiding the safety hazards caused by high-altitude operations.

[0045] Four through holes 20 are provided at the top and bottom of the inner wall of the window frame 1. One end of the upper connecting rope 11 passes through the through hole 20 and wraps around the outside of the two upper guide wheels 9 located at the same end. One end of the lower connecting rope 10 passes through the through hole 20 and wraps around the outside of the two lower guide wheels 8 located at the same end.

[0046] Both ends of the first sliding horizontal plate 12 and the second sliding horizontal plate 5 are provided with stabilizing components, and the stabilizing components include an opening 15, and the opening 15 is opened at one end of the first sliding horizontal plate 12 and the second sliding horizontal plate 5. A slider 17 is provided inside the opening 15, and one end of the slider 17 extends to the inside of the slide groove 19, and both sides of the slider 17 are in sliding contact with the inner wall of the slide groove 19.

[0047] A rotating shaft 1 25 and a rotating shaft 2 26 are provided in the first sliding horizontal plate 12 and the second sliding horizontal plate 5 . Rollers 16 are provided at both ends of the rotating shaft 1 25 . The two rollers 16 are located in the sliders on the corresponding side, and each slider is provided with a groove 21 on the side facing the insulating glass 32 . The rollers 16 extend out of the groove 21 and slide in contact with the inner wall of the slide groove 19 .

[0048] The cleaning cotton 18 is provided with through slots 22 on the first and second push-pull horizontal plates 12 and 5, respectively, on the upper and lower sides. Two gears 1 27 are provided on the rotating shaft 1 25, and a gear 2 28 is provided on the rotating shaft 26, which meshes with the two gears 1 27 in a one-to-one manner. A flip plate 23 is provided on the rotating shaft 26, and the flip plate 23 is hinged to the wiper 24 on its upper and lower sides. The wiper 24 extends through the through slot 22 on the corresponding side and contacts the insulating glass 32. The roller 16 has a smooth surface, and the friction between the roller 16 and the groove is less than the friction between the wiper 24 and the sides of the insulating glass window. This allows the roller 16 to idle when the wiper 24 contacts the sides of the insulating glass window, preventing the roller 16 from continuing to rotate and damaging the wiper 24.

[0049] The above principle is also a method for cleaning an insulating glass window, which is a double-sided demisting method for an insulating glass window, and a method for demisting an insulating glass window on both sides by using the cleaning cotton and the wiper 24.

[0050] During use, to clean the glass, first fill the water reservoir 13 with water. The water inside will flow through the water pipe 14 to the side of the outer glass 2, flowing along the outer glass 2, and then rinse the inner glass 3 with water. At this time, you can manually pull the first sliding horizontal plate 12 downward, moving the cleaning cotton 18 inside, thereby cleaning the inner glass 3. When the first sliding horizontal plate 12 is pulled downward, the end of the upper connecting rope 11 connected to the first sliding horizontal plate 12 moves downward synchronously, and the end of the upper connecting rope 11 connected to the second sliding horizontal plate 5 moves upward, thereby moving the second sliding horizontal plate 5 upward, which in turn drives the cleaning cotton 18 on the side of the second sliding horizontal plate 5 to clean the outer glass 2. At the same time, the roller 16 rotates in the direction of movement of the first push-pull horizontal plate 12 and the second push-pull horizontal plate 5. Through the linkage between the first rotating shaft 25, the second rotating shaft 26, the first gear 27 and the second gear 28, the flip plate 23 rotates with the second rotating shaft 26 and then falls behind the cleaning cotton 18 to contact the outer glass 2 and the inner glass 3. Then, the wiper 24 can follow behind the cleaning cotton 18 to scrape off the residual cleaning water. When the first push-pull horizontal plate 12 moves to the bottom, the second push-pull horizontal plate 5 moves to the top, and then pulls the first push-pull horizontal plate 12 upward. This reciprocating movement drives the first push-pull horizontal plate 12 and the second push-pull horizontal plate 5 to move alternately, completing the cleaning operation.

[0051] A convenient cleaning device for insulated glass windows, which is attached to the window structure and can clean both sides simultaneously, has been developed. It is very practical.
