    Abstract: The present invention relates to an improved water safety airbag structure, which includes a case, a bag and a holding receptacle, and the bag provided with the holding receptacle is retained within the case. The bag and the holding receptacle are respectively filled with a powdered chemical and an acidic chemical liquid. When the user is in difficulties during activities on the water, oppositely directed external forces can be applied to the bag and two sides of the holding receptacle, thereby causing the powdered chemical and acidic chemical liquid within the bag and the holding receptacle to mix and produce a large amount of gas to inflate the bag, thus achieving the effectiveness to save the life of the person in difficulties on the water.
