[0002] The factory building ventilation skylight is a facility installed on the roof of industrial building, which is used for natural ventilation and lighting. Its main function is to promote air flow by using the thermal pressure difference or wind pressure difference generated by the indoor and outdoor temperature difference without using electricity or other energy, so as to improve indoor air quality, heat dissipation, dehumidification and lighting.

[0003] The connected ventilation skylight refers to a ventilation system formed by connecting multiple ventilation skylight units through structure. This skylight design is usually used in large-area industrial plants, warehouses, sports venues and other buildings to improve the overall ventilation efficiency and the aesthetics of the building. Compared with installing multiple independent skylights, the installation process of the connected ventilation skylight is simpler, which can save installation time and cost, so it is widely used. The existing connected ventilation skylight is mainly opened by two ways, folding and sliding. The folding refers to the window sash being turned up or down along the horizontal axis. The sliding refers to the window sash being pushed and pulled along the track horizontally, which can be partially or fully opened. However, the sealing requirement of the joint gap of the window sash is high for both ways. Over time or during installation, the position deviation of the sealing strip will cause water leakage in rainy and snowy weather. The installation difficulty is high, and the maintenance cost is high.
