Abstract

The utility model relates to a soft face mask overlapping-pipe type underwater breathing apparatus used in deep water and surging water. The soft face mask is used for sealing the periphery of a nose and a mouth; an air intake valve and an air exhaust valve which are in an overlapped shape are sheathed by a communicating pipe on the face mask; an air intake pipe and an air exhaust pipes are respectively connected with the air intake valve and the air exhaust valve, then pass through a safe floater in the overlapping shape and penetrate into a breathing floater. A geometric center point of the opening of the air intake pipe and the breathing floater is connected with a geometric centre bore, and the opening of the air exhaust pipe continuously penetrates out of the breathing floater after passing through the geometric centre point. The utility model is the underwater breathing apparatus which has more convenient use and better breathing effects.

Description

Soft face mask is folded cast deep water, burbulent water rebreather

Affiliated technical field

It is the underwater breathing apparatus, particularly deep water of source of the gas, the rebreather under the burbulent regimen condition with the atmosphere that the utility model relates to a kind of.

Background technology

More later-model rebreather is that my patent No. of application is the rebreather of 200320110899.X at present, it is mainly by aspirate tube, freeing pipe, face shield, safe float, breathe float, formation such as the stopper of restricting water supply, there is an end of check valve to be connected in aspirate tube, the freeing pipe with mask seal, the other end passes safe float, the breathing float communicates with the geometric centre hole to the geometric centre place of breathing float, the inboard limited water stopper in centre hole two ends.But the buoyancy of aspirate tube, freeing pipe is bigger.The balancing force that suspends in the water is big (promptly will fasten heavier hypostasis), and the gas in aspirate tube, the freeing pipe forms miscellaneous gas in the geometric centre hole, and quality and efficient are breathed in influence, uses the hard face shield also to bother simultaneously.

Summary of the invention

Be difficult for sinking in order to overcome existing rebreather freeing pipe, breathe of poor quality, the hard face shield uses the deficiency of trouble, and the utility model provides a kind of rebreather, and face shield is made with soft material, use more convenient, aspirate tube and freeing pipe are overlapping, and buoyancy descends, easier suspension, the gas of freeing pipe, air inlet pipe does not have mixing, breathes the quality height.

The technical scheme that its technical matters that solves the utility model adopts is: freeing pipe is penetrated in the aspirate tube, shape in an overlapping, freeing pipe changes the soft small hose of no liner steel wire into, overlappingly pass safe float, and pierce into the breathing float, the aspirate tube mouth of pipe communicates with the geometric centre hole at the geometric centre place, and freeing pipe continues to pass the breathing float after passing the geometric centre place.Overlapping suction, the freeing pipe other end are connected with air suction valve, the blow off valve of overlapping shape respectively, and blow off valve is overlapped in the air suction valve, are spaced from each other, and air-breathing valve leather is opened when air-breathing, and the exhaust valve leather is closed, and the exhaust valve leather is opened during exhaust, and air-breathing valve leather is closed.Air suction valve is through in the connection pipe of soft face shield, and four jiaos of soft face mask have four buttonholes, is buckled with two pairs of lassos up and down above, and top lasso entangles head from the ear top, and following lasso entangles head from back side of head position.Soft face mask top has two rhinobyons to be positioned at the opposite side of connection pipe, can make the stuffiness of nose jam-pack during use, not intake, and can breathe (oral cavity parts a little) smoothly to guarantee the oral cavity.

The beneficial effects of the utility model are, more convenient, sealing that soft face mask uses, the balancing force in the plastic pipe water in suspension reduces greatly, draw more convenient, no gas mixing, effciency of respiratory height.

Among the figure 1, face shield, 2, buttonhole, 3, nasal obstruction, 4, connection pipe, 5, blow off valve, 6, the exhaust valve leather, 7, air-breathing valve leather, 8, air suction valve, 9, freeing pipe, 10, aspirate tube, 11, breathe float, 12, the stopper of restricting water supply

The specific embodiment

Four jiaos of face shield in Fig. 1 (1) have four buttonholes (2), are buckled with two pairs of lassos up and down above, and top lasso entangles head from the ear top, and following lasso entangles head from back side of head position.The top of face shield (1) has a pair of (two) nasal obstructions (3) to be used for jam-pack nose hole, make do not intake, stuffiness.The side in addition of nasal obstruction (3) has connection pipe (4) to be enclosed within the suction end of the air suction valve (8) among Fig. 3 among Fig. 2, and air-breathing valve leather (7) is arranged in the air-breathing pipe end, and the other end of air suction valve (8) and aspirate tube (10) one ends are tightly connected.The inside of air suction valve (8) is folded blow off valve (5), and exhaust valve leather (6) is arranged in the exhaust side of blow off valve (5), and the other end and freeing pipe (9) are tightly connected.Freeing pipe (9) is the soft small hose of no liner steel wire, it penetrates in the aspirate tube (10), shape in an overlapping, pass safe float and pierce into and breathe float (11) among Fig. 4, aspirate tube (10) mouth of pipe communicates with the geometric centre hole at the geometric centre place, after freeing pipe (9) mouth of pipe passes the geometric centre place, continue to pass breathing float (11).

Claims

1, a kind of soft face mask is folded the burbulent water rebreather of cast deep water, it is by face shield, inhale, drain tap, inhale, freeing pipe, safe float, the breathing float constitutes, it is characterized in that: four jiaos of face shield have four buttonholes, be buckled with two pairs of lassos up and down on the buttonhole, a pair of nasal obstruction is arranged at the top of face shield, the side in addition of nasal obstruction has connection pipe to be enclosed within the suction of overlapping shape, on the drain tap, the suction of overlapping volt, freeing pipe one end respectively with suction, drain tap is tightly connected, the other end passes safe float and pierces into the breathing float, the air-breathing mouth of pipe communicates with the geometric centre hole to the geometric centre place, and exhaust pipe mouth continues to pass behind the geometric centre place to be breathed outside the float.
