An underwater breathing mask for Bama miniature pigs

Abstract

The invention relates to an underwater breathing mask for Bama miniature pigs. The underwater breathing mask comprises a silica gel sleeve (1), a hard shell (2), a first circular supporting plate (3),a second circular supporting plate (7), a plurality of ventilation copper pipes (4) and a plurality of silica gel pads (6); the silica gel sleeve (1) is of a straight cylindrical structure with an opening in one end, and the opening is in a horn shape; the silica gel sleeve (1) is divided into a first rubber sleeve section (8) and a second rubber sleeve section (9); the first rubber sleeve section (8) is nested in the hard shell (2), and a first circular supporting plate (3) and a second circular supporting plate (7) are correspondingly arranged on the outer side and the inner side of the first rubber sleeve section (8) respectively; wherein the hard shell (2) is of a straight cylindrical structure with an opening at one end; and the two ventilation copper pipes (4) are respectively and correspondingly inserted inwards from the round holes on the hard shell (2), and the silica gel pads (6) are arranged between the two ventilation copper pipes (4).

Description

technical field [0001] The invention belongs to the technical field of animal husbandry machinery and underwater diving breathing life, and in particular relates to an underwater breathing mask for Bama miniature pigs. Background technique [0002] The underwater breathing support system generally consists of a high-pressure cylinder, a regulator, and a breathing mask. Under the action of the regulator, the air pressure in the high-pressure gas cylinder is reduced to a safe level suitable for inhalation, avoiding the consequences of direct breathing damage to the diver's lungs. [0003] The working principle of the underwater breathing support system: the diver inhales to make the pressure in the breathing mask lower than the ambient water pressure; the water pressure squeezes inward to open the valve or piston in the regulator; the opened valve or piston releases the high pressure The gas cylinder is connected to the breathing mask; air flows into the breathing mask from t...

AI Technical Summary

Problems solved by technology

As for the requirement of terrestrial mammals to move or work underwater, there is currently no relevant research results on respiratory masks for mammals, resulting in the inability of terrestrial mammals to survive underwater for a long time
