Embodiment 1:

The aqualung that is used to dive under water.

Fig. 1 cutaway view when working in the water, Fig. 2 be A to view, Fig. 3 be B to view, Fig. 4 is the B-B cutaway view.

As shown in Figure 1 and Figure 2, the annular arrangement ball float (1) that is filled with the 0.5-0.7kgf/cm2 pressed gas and opening container (2) down link to each other, and some induction openings (3) are arranged at the top, and bosom has an inverted container (4), is referred to as air storing cavity.Mouth fuses with gusset (11) apart from water surface 60mm at the bottom of the air storing cavity.Along axis a hard tube (9) is arranged in the chamber, the hard tube end opening communicates with aspirate tube (13), hard tube is suitable for reading to communicate with annular arrangement floating drum (1) through charging valve (5), there is suction inlet (7) at the hard tube middle part, make that air communicates with the hard tube upper and lower opening in the chamber, and be with a ball float (10) and hang on suction inlet (7) with pivot pin (8), ball float moves up and down with water level in the chamber, drives the keying that valve rod (6) comes by-pass valve control (5) by ball float pivot pin (8).Gusset (12) fuses hard tube and air storing cavity.

During work, the gas production chamber floats on the water surface under floating drum (1) buoyancy, and water surface air enters through induction opening (3), flows to the air storing cavity admission port downwards, upwards flows to suction inlet (7) again.The water droplet of sneaking into plays the effect of gas-water separation in motional inertia, the dirty backwater of action of gravity.It is air-breathing for human body that the gas storage intracavity gas enters aspirate tube (13) arrival breathing mouth (14) through suction inlet (7).If the gas production chamber overexerts owing to diving or water surface wave such as hits at reason, and enters in the water, the gas storage intracavity gas makes water can not be full of air storing cavity, but along with human body is air-breathing, the gas storage intracavity gas reduces, and water level must rise in the chamber, along with water level constantly rises.Ball float (10) backs down charging valve (5) by valve rod (6) under buoyancy, make the interior gas of floating drum (1) under pressure, charge into air storing cavity, water level descends in the compressing chamber, and along with water level descends, ball float (10) is closed charging valve (5) because of loss of buoyance.Repeatedly continuous like this, make to have certain amount of air in the air storing cavity.Play the effect of water shutoff tonifying Qi.The gas production chamber is owing to the effect of float buoyancy, and the gas production chamber will constantly be tried to achieve balance and be bubbled through the water column.By the time the gas production chamber emerges, ponding by gravity in the air storing cavity flows back in the water, the work that returns to normal of gas production chamber.

Aspirate tube (13) is to bear hydraulic pressure and crooked snake-like hose.One end links to each other with the indoor hard tube of gas production (9) end opening, and the other end links to each other with breathing mouth air suctiton inlet (14).

Breathing mouth is the uncovered device of rubber of energy capping human body mouth and nose, as shown in Figure 3, Figure 4.Breathe in the mouth exhale, air suctiton inlet (15) is made up of two check valves (14), (16), with aspirate tube (13), exhaust tube (17) communicates respectively, exhaust tube is made one with the breathing mouth expiration is entered in the water.

During use, breathe mouth with human body mouth and nose cap seal, and fasten with rope (18), the oral cavity contains and exhales, air suctiton inlet (15), has so both met the swimming custom of breathing in the oral cavity, has the effect of dual water shutoff again.When human body is air-breathing, form negative pressure in the oral cavity, valve (16) cuts out under the hydraulic pressure effect, and valve (14) is opened under air storing cavity air pressure (being generally barometric pressure) effect, and air storing cavity gas enters human body.During expiration, valve (14) cuts out under the breath pressure effect, and valve (16) is opened.Exhale and enter in the water by exhaust tube (17).

This aqualung, gas production chamber buoyancy is big, center of gravity is low, and is little with dynamic resistance, even enter in the water, air storing cavity still has certain amount of air, is suitable for work drowned.
