Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
As shown in fig. 1-3, the utility model provides an breathing bag for an underwater diving device, which comprises a bag body 1, wherein a flange plate 2 is arranged on the bag body 1, the flange plate 2 is used for being connected with an expiration pipeline, a drain valve 3 is also arranged on the bag body 1, and the drain valve 3 is used for draining water entering the bag body 1 when a human body exhales, so that the phenomenon that the use of the breathing bag is influenced due to the fact that more water remains in the bag body 1 after the breathing bag is used for a long time is avoided.
More specifically, the bag body 1 includes an outer bag body 11 and an inner bag body 12 provided inside the outer bag body 11, the outer bag body 11 is a cloth bag, the inner bag body 12 is a rubber bag, the flange plate 2 is mounted on the outer bag body 11 and is communicated with the inside of the inner bag body 12, and the drain valve 3 is mounted on the outer bag body 11 and is communicated with the inside of the inner bag body 12.
