At this time, people can directly push the glass frame, and the glass frame and the connecting rod rotate through the rotating shaft, so that normal opening and ventilation of the glass frame can be achieved. When people need to clean the glass plate, the staff can rotate the third rotating block, which can drive the second threaded screw to rotate. When the second threaded screw rotates During the process, the second threaded sleeve engaged on its outer wall can drive the second guide cylinder and the clamping column to move in the direction away from the clamping slot until the clamping column is completely separated from the clamping slot. At this time, the fixation between the connecting rod and the glass frame is released and a rotational connection is formed. At this time, people can rotate the glass frame. Through the action of the fourth rotating column, the glass frame can be turned inside out, and the glass plate outside the glass frame can be turned inside, thereby facilitating people to quickly clean the inside and outside of the glass plate. The entire cleaning process can be completed only in the car, which not only improves people's cleaning efficiency of the glass plate, but also has higher safety, meeting people's usage needs.

[0025] The present invention provides a ventilation window structure for RVs that is easy to clean. Through the provision of a gauze net and a brush roller, and through the gauze net provided on the inner side of the glass frame, people can prevent mosquitoes from flying in while ventilating the car, thereby playing a good isolation role. When people do not need the gauze net, the magnetic strip can be pulled out from the inside of the matching groove and the second rotating block can be rotated. The second rotating block can drive the rotating rod to rotate, and during the rotation of the rotating rod, the first bevel gear can be driven to rotate. The meshing between the first bevel gear and the second bevel gear can drive the winding roller to rotate. When the winding roller rotates, the winding of the gauze net can be effectively completed. Since the gauze net is magnetically fixed, it is convenient for people to disassemble and clean it, and it will contact the brush roller during the winding process of the gauze net. The mosquito corpses, dust, etc. remaining on the surface of the gauze net can be brushed off by the brush roller, thereby achieving effective cleaning of the surface of the gauze net.

[0026] The present invention provides a ventilation window structure for a motor home that is easy to clean. Through the cleaning component that is set, the second transmission wheel can be driven to rotate through a rotating rod. During the rotation of the second transmission wheel, the first transmission wheel can be driven to rotate through a transmission belt. During the rotation of the first transmission wheel, the third rotating column can be driven to rotate. The rotation of the third rotating column can drive the driving gear to rotate. Through the meshing transmission between the driving gear and the first gear and the second gear, the fan blades inside the second cavity can be driven for transmission. When the fan blades rotate, negative pressure suction can be generated inside the second cavity. The fan blades are all arranged on the outside of the gauze net, so that the gauze net can be better cleaned and dusted in cooperation with the brush roller, thereby reducing the frequency of people disassembling the gauze net for manual cleaning. Impurities generated during the cleaning process will fall into the dust exhaust trough through the slope block, and people can regularly open the cover plate to clean the dust exhaust trough.
