The invention relates to a simple deepwater breathing device. The device comprises air inlet rods, a sealed box body, a hollow guide pipe and a mouthpiece. Four evenly-distributed air inlets are formed in the top of the sealing box body, and a one-way valve is arranged on the center of the lower portion of the sealing box body; the one-way valve and the sealing box body are provided with a penetrating central hole; a thickening mode is adopted in the bottom of the sealing box body; and one end of each air inlet rod penetrates the corresponding air inlet to stretch into the sealing box body. One end of the central guide pipe penetrates the central hole to stretch into the sealing box body, and the other end of the hollow guide pipe is connected with the mouthpiece. The simple deepwater breathing device is simple in structure and convenient to use. The fall of the distance between the air inlet rods and the water surface is large, and water cannot easily enter the sealing box body through the air inlet rods, so that safety of a user is ensured. The bottom of the sealing box body is thickened, and the weight of the sealing box body is increased, so that the stability of the sealing box body is ensured, and the phenomenon that the sealing box body inclines and the water enters the sealing box body is avoided; the one-way valve is arranged in the sealing box body, and air breathed out fromthe underwater user is prevented from entering the sealing box body; and the content of oxygen in the sealing box body is ensured.
