DETAILED DESCRIPTION
[0020] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Example 1
[0021] See also Figure 1-Figure 6The adjustable building lighting window structure in one embodiment of the present invention comprises a window sash assembly 1, wherein the window sash assembly 1 comprises a window sash housing 101, a screw rod 102 and a water retaining rack 103, wherein two sets of screw rods 102 are rotatably mounted on the window sash housing 101, and a water retaining rack 103 is fixedly arranged on one side of the window sash housing 101; a window frame assembly 2, wherein the window frame assembly 2 comprises a window frame housing 201 and a movable frame 202, wherein the window frame housing 201 is rotatably mounted on one end of the window sash housing 101, and one end of the movable frame 202 is movably connected to the window sash housing 101, and the movable frame The other end of 202 is movably connected to the window frame shell 201; a cleaning component 3, the cleaning component 3 includes a cleaning roller 301, a driven block 302 and a driven gear 303, the cleaning roller 301 is movably arranged on one side of the window sash shell 101, and is arranged on the outer side of the glass of the window sash shell 101, the two groups of driven blocks 302 are respectively meshed with the two groups of screw rods 102, the cleaning roller 301 is rotatably assembled on the two groups of driven blocks 302, and a driven gear 303 is also fixedly arranged on one end of the cleaning roller 301, and the driven gear 303 is meshed with the water retaining rack 103.
[0022] In actual application of this embodiment, when the adjustable skylight structure is used, the window sash housing 101 and the window frame housing 201 are connected to each other with a fixed axis for rotation, and the window frame housing 201 is fixedly arranged at one end of the building. When the user rotates to open and close the window sash housing 101, the window sash housing 101 and the window frame housing 201 are connected to each other through the transmission member 5. Therefore, the transmission member 5 can drive the two sets of screw rods 102 to rotate during the rotation of the window sash housing 101. The screw rods 102 can mesh and drive the two sets of driven blocks 302 to move in a directional manner on the window sash housing 101 during the rotation, so that the cleaning roller 301 moves synchronously with the two sets of driven blocks 302. Since the driven gear 303 at one end of the cleaning roller 301 is connected to the water retaining rack 103 The cleaning roller 301 is meshed with each other, so during the movement of the cleaning roller 301, the cleaning roller 301 can be driven to rotate, so that the cleaning roller 301 rotates to remove stains on the glass surface of the window sash shell 101. After the light window is closed, when the external environment is in a rainy state, the rainwater contacts the glass surface of the window sash shell 101 and flows along the glass surface, and is stored in the water storage tank 203 on one side of the window frame shell 201 through the flow. When the light window is opened, during the process of the cleaning roller 301 cleaning the glass surface, the pump flow component 4 arranged at one end of the window sash shell 101 can also draw the stored rainwater from the water storage tank 203, and spray the rainwater to one side of the glass surface of the window sash shell 101, thereby cooperating with the cleaning roller 301 to clean the dirt on the glass surface, thereby improving the light transmittance of the glass surface and increasing the daylighting rate.
[0023] See also Figure 3 and Figure 6In a preferred embodiment of the present invention, the window sash assembly 1 further includes a first water guide hole 104, a second water guide hole 105, a baffle 106, a first drain hole 107 and a second drain hole 108. The first water guide hole 104 and the second water guide hole 105 are respectively arranged at both ends of the water retaining rack 103. The baffle 106 is elastically slidably assembled on one side of the water retaining rack 103. The baffle 106 is used to movably block the first water guide hole 104 and the second water guide hole 105. The baffle 106 is also provided with a first drain hole 107 and a second drain hole 108. 8, the first drain hole 107 and the second drain hole 108 are respectively arranged close to the first water guide hole 104 and the second water guide hole 105; the window sash assembly 1 also includes a first drainage groove 109 and a second drainage groove 110, and the window frame assembly 2 also includes a water storage tank 203, the first drainage groove 109 is arranged on one side of the first water guide hole 104, the second drainage groove 110 is arranged on one side of the second water guide hole 105, the water storage tank 203 is arranged at one end of the window frame shell 201, and the first drainage groove 109 is communicated with the water storage tank 203.
[0024] In actual application of this embodiment, the water retaining rack 103 is provided with a first water guide hole 104 and a second water guide hole 105, and the baffle 106 is slidably provided at one end of the water retaining rack 103 for movably blocking the first water guide hole 104 and the second water guide hole 105, and the baffle 106 is provided with a first drainage hole 107 and a second drainage hole 108, so that the baffle 106 can switch the conduction state of the first water guide hole 104 and the second water guide hole 105 during the sliding process. When the skylight is in the closed state, the baffle 106 is assumed to slide against one side of the window sash housing 101, and at this time, the first water guide hole 104 and the first drainage hole 107 are aligned, so that the first water guide hole 104 is in the conduction state, and at this time, the second water guide hole 105 and the second drainage hole 108 are misaligned, so that the second water guide hole 105 is in the closed state, and at this time, rainwater from the outside can flow along the glass surface The rainwater flows into the first water guide hole 104, passes through the first water guide hole 104 and converges into the first drainage groove 109. Since the first drainage groove 109 is connected to the water storage tank 203, the rainwater can be stored in the water storage tank 203. When the skylight is opened, during the opening process, the baffle 106 slides on the window sash shell 101 to misalign the first drainage hole 107 and the first water guide hole 104, and at the same time, the second water guide hole 105 and the second drainage groove 110 are aligned. At this time, the second water guide hole 105 and the second drainage groove 110 are in a conducting state. When the rainwater in the water storage tank 203 is sprayed onto the glass surface of the window sash shell 101 through the pump flow component 4, the sewage after cleaning the glass surface can converge into the second drainage groove 110 along the second water guide hole 105, and be discharged out of the skylight from the drainage port at one end of the second drainage groove 110, so that the glass surface of the skylight is in a clean state.
[0025] In one case of this embodiment, the window frame shell 201 is installed on the building surface at an angle by default, and the first water guide hole 104 and the second water guide hole 105 are both arranged at a low position in the spatial direction, so that rainwater can flow to the first water guide hole 104 or the second water guide hole 105 when sliding along the glass surface.
[0026] See also Figure 3 In a preferred embodiment of the present embodiment, the cleaning component 3 also includes a linkage block 304, which is limitedly slidably assembled on one end of the window sash shell 101, and one end of the linkage block 304 is rotatably connected to the cleaning roller 301, and the other end is movably abutted against the baffle 106.
[0027] In actual application of this embodiment, the linkage block 304 is limitedly slidably set at one end of the window sash shell 101, and one end of the water retaining rack 103 is rotatably assembled on the linkage block 304. Therefore, when the cleaning roller 301 moves in a directional manner under the drive of the driven block 302, the linkage block 304 moves synchronously with the cleaning roller 301, and the linkage block 304 can abut against the baffle 106 during the process of sliding toward the side of the window sash shell 101, and the baffle 106 overcomes the elastic force and is pressed against one side of the window sash shell 101. At this time, the first water guide hole 104 is in an open state and the second water guide hole 105 is in a closed state.
[0028] See also Figure 6 In a preferred embodiment of the present invention, the cleaning component 3 also includes a guide groove 305, a sliding pin 306, a toothed disc 307 and a synchronous belt 308. The guide groove 305 is fixedly arranged on one side of the window sash housing 101, the sliding pin 306 is limitedly slidably assembled on the guide groove 305, the toothed disc 307 is rotatably assembled on the sliding pin 306, one end of the synchronous belt 308 is fixedly arranged on one side of the window sash housing 101, and the other end of the synchronous belt 308 is passed through the toothed disc 307 and fixed to one end of the linkage block 304.
[0029] When this embodiment is actually used, when the linkage block 304 follows the movement of the cleaning roller 301, one end of the linkage block 304 is fixedly connected to the synchronous belt 308, and the end of the synchronous belt 308 is fixedly set at the other end of the window sash shell 101, and the synchronous belt 308 is meshed and assembled with the toothed disc 307. Therefore, when the linkage block 304 pulls the synchronous belt 308 to move, the sliding pin 306 slides synchronously on the guide groove 305, and the movement stroke of the sliding pin 306 and the sliding pin 306 is half of the linkage block 304, and one end of the sliding pin 306 is movably connected to the pump flow rod 403. Therefore, during the reciprocating sliding process, the linkage block 304 can synchronously drive the pump flow rod 403 to reciprocate. Since the pump flow rod 403 is fixedly connected to the piston inside the pump flow cylinder 402, the inner cavity of the pump flow cylinder 402 can be switched between positive and negative pressure states, thereby sucking out rainwater in the water storage tank 203 and spraying it onto the glass surface of the window sash shell 101.
[0030] See also Figure 2 , Figure 3 and Figure 4 In a preferred embodiment of the present invention, the adjustable building skylight structure also includes a pump flow component 4, which includes a sleeve 401, a pump flow cylinder 402, a pump flow rod 403, a first guide pipe 404, a second guide pipe 405 and a water spray pipe 406.

[0031] In actual application of this embodiment, the sleeve 401 and the pump flow cylinder 402 are fixedly assembled on one end of the window sash shell 101, and the pump flow rod 403 can also pull the pump flow rod 403 to move synchronously during the movement, so as to adjust the positive and negative pressure state inside the pump flow cylinder 402. When the interior of the pump flow cylinder 402 is in a negative pressure state, rainwater inside the water storage tank 203 can be sucked into the pump flow cylinder 402 along the second guide pipe 405; when the interior of the pump flow cylinder 402 is in a positive pressure state, rainwater can be output along the first guide pipe 404 to the water spray pipe 406, and sprayed onto the glass surface of the window sash shell 101 through the water spray pipe 406.
[0032] In one case of the present embodiment, one end of each of the first guide tube 404 and the second guide tube 405 is provided with a one-way valve to limit the one-way flow of the fluid thereon, which can limit the one-way flow of the fluid from the pump flow tube 402 into the first guide tube 404, and can limit the one-way flow of the fluid out of the pump flow tube 402 along the second guide tube 405.
[0033] See also Figure 4 In a preferred embodiment of the present invention, the adjustable building skylight structure also includes a transmission component 5, which includes a fixed gear 501, a main gear 502, a center wheel 503 and a driven wheel 504.

[0034] In actual application of this embodiment, the fixed gear 501 is fixedly arranged on one side of the window frame shell 201. When the window sash shell 101 rotates around the connecting shaft, the main gear 502 is meshed with the fixed gear 501 and drives the driven wheel 504 to rotate through the intermediate wheel 503 at one end thereof. The transmission ratio between the main gear 502 and the intermediate wheel 503 is less than 1, and the transmission ratio between the intermediate wheel 503 and the driven wheel 504 is less than 1, so that the driven wheel 504 rotates at a faster speed relative to the main gear 502.
