Abstract

A safe aqualung belongs to the diving apparatus technical field. The invention is characterized in that an air plastic pipe is connected to a calabash-shaped plastic water diversion air chamber and an upper air chamber and is connected with a respiration head of a face mirror through an air pipe, a movable joint and an air pipe of a stainless steel pipe. The other movable joint of the air pipe is connected with a buoy which can be inflated. The bottom part of the calabash-shaped air chamber is provided with a check valve; two frames are connected with horizontal EVC foam. The middle part of the EVC foam is provided with a knob and two living-knot ropes; a lower fixing card of the EVC foam is provided with a fixing head of a deep diving part. The invention has the beneficial effects that the calabash-shaped air chamber is adopted, and if a small quantity of water enters, the water is discharged by the check valve at the bottom part of the air chamber. The floating force of the EVC foam exposed at the exterior of the stainless steel can be used as the buoy; when people feel tired, the knob and the two living-knot ropes can be adopted to fix both hands, which is safe and reliable. The deep diving part can increase the diving depth; the invention is more convenient and practical in economy and application.

Description

technical field

[0001] A safety diving respirator belongs to the technical field of diving equipment. Background technique

[0002] Currently known personal diving breaths in shallow seas include the oxygen type and the direct air inhalation type. As for the direct air suction type, when water enters the air inlet, it is easy to cause the user to panic due to choking of water and cause safety problems. General diving respirators do not have life-saving devices, and the depth of diving is very shallow, and they cannot be used when there are wind and waves. Contents of the invention

[0003] The object of the invention is to overcome the safety deficiency of the existing direct breathing air submersible and propose.

[0004] The technical scheme of the present invention is that the air plastic pipe (2) of the respirator is connected to the gourd-shaped plastic water-distributing air chamber (4), and an air inlet is respectively opened on the left and right of the air plast...
