The function of natural ventilators is to use the pressure difference between indoor and outdoor air and wind pressure to achieve natural ventilation, continuously provide fresh air to the room, and thus circulate indoor and outdoor air. And because natural ventilators do not require electricity, they meet the requirements of energy conservation and environmental protection.

[0003] Existing natural ventilators usually include a shell with a ventilation cavity formed inside the shell. The side of the shell facing the room is provided with an indoor air outlet connected to the ventilation cavity. The side of the shell facing the outside is provided with an outdoor air inlet connected to the ventilation cavity. The side of the shell facing the room is provided with an opening and closing device for controlling the opening or closing of the indoor air outlet. Filters are respectively provided at the indoor air outlet and the outdoor air inlet.
