A respiratory mask includes a mask body and an air inlet connector. The mask body is formed with an air inlet. The air inlet connector is integrally formed at the air inlet. The respiratory mask can be direct connected to an oxygen tube, an air storage bag, a mist spray tank, a medicine feed tank or a standard air tube of 22 mm, without the need for a separate connector. The respiratory mask decreases the number of the parts and is easy to operate for medical workers to change different pipes, without changing the respiratory mask.
