Abstract

A positive-negative pressure bellows has a body, a two-way ventilation fan, a filter, and a wind-collecting cover. The body has two shutters respectively mounted on an indoor side window and an outdoor side window, which are respectively located at two ends of a channel of the body. The two-way ventilation fan, the filter, and the wind-collecting cover are mounted in the channel of the body. The two-way ventilation fan adjusts a wind direction and the two-way ventilation fan adjusts an air flow direction through the shutters. The filter is located between the two-way ventilation fan and the outdoor side window. The wind-collecting cover is located between the two-way ventilation fan and the indoor side window. When the positive-negative pressure bellows is used in a positive pressure space or a negative pressure space, the air flow direction of the two-way ventilation fan is changed according to the needs of an indoor space. In a positive pressure purpose, the air flow direction is from inside to outside. In a negative pressure purpose, the air flow direction is from outside to inside, and since the filter is adjacent to the indoor side window, the filter can be replaced or cleaned in a negative pressure function to prevent the pollutants from affecting the indoor space.
