[0002] A skylight roof is a building structure design that uses transparent or translucent materials to cover the roof to introduce natural light and reduce dependence on artificial lighting. This design not only saves energy, but also creates a bright and comfortable indoor environment. Skylight roofs are usually combined with the exterior design of the building to ensure its structural stability and aesthetics, while also taking into account functional requirements such as insulation and waterproofing. When designing, the inclination angle of the roof must also be considered to maximize the use of natural light.

[0003] The existing Chinese patent with publication number CN116816002A discloses a lighting roof building structure, including a roof, a skylight and a cleaning mechanism. A light-transmitting opening is provided at the top of the roof. The skylight includes a window frame installed at the light-transmitting opening and a lighting glass installed in the window frame. The cleaning mechanism includes a cleaning plate provided on the top of the lighting glass and a driving assembly for driving the cleaning plate to move on the top of the lighting glass to clean dust or other debris on the top of the lighting glass. When dust or other debris on the skylight affects the light transmission effect of the skylight, the driving assembly can drive the cleaning plate to move on the skylight to clean the dust or other debris on the top of the skylight, so as to avoid the dust or other debris on the skylight affecting the light transmission effect of the skylight. People do not need to climb onto the roof to clean the dust or other debris on the top of the skylight. The use is safe and has a good cleaning effect. It can also save people's time and energy. However, the patent does not have the function of drying the skylight after wiping it with a wet sponge. There will be a lot of dust attached to the surface of the skylight.

Through the setting of the air permeable grooves 112, the storage rack 11 is ventilated and rainwater is prevented from entering the storage rack 11.

[0043] Specifically, when it is necessary to clean the window, the two groups of electric push rods 21 are turned on, the electric push rods 21 drive the extension rods 22 to extend, and then drive the two groups of push blocks 23 to move along the inside of the slide groove A121, and use the cross plate 27 and the soft brush 28 to scrape the dust on the surface of the light-transmitting window 3, and then use the cleaning cotton 241 and the absorbent cotton 26 to wipe the surface of the light-transmitting window 3. During the movement of the push block 23, the water pipe B46 and the sealing plate 461 are compressed, thereby squeezing the air inside the water pipe A45. Through the setting of the one-way pressure valve B443, the air can be squeezed out of the water pipe B46. When the air inside the water pipe A45 is compressed, the liquid inside the water storage chamber 442 is prevented from flowing out of the filter 441. When the air is not squeezed, the water stored in the collection box 41 can flow from the filter 441 into the water storage chamber 442 for replenishment. The water inside the water storage chamber 442 is squeezed into the water suction pipe 47. The water enters the water pipe B46 through the water suction pipe 47 and flows from the water replenishment groove 242 to the cleaning cotton 241, thereby moistening the cleaning cotton 241, and cooperates with the absorbent cotton 26 for wet wiping and dry wiping, thereby achieving the purpose of automatic cleaning and filling and preventing water stains.
