Abstract

The utility model relates to a combined underwater breather which radically prevents choking in water and has simple structure. The combined underwater breather consists of an inflatable water ring 1, an air chamber 2, a corrugated hose 4 and a breathing nozzle 5. The air chamber is provided with hollow thin pipes which are connected with air intake/discharge hole 3 positioned around the top of the air chamber, are bent upwards and then downwards and then are communicated to the bottom of the air chamber; and another air intake/discharge hole of a breathing air pipe passing through the bottom of the air chamber is arranged at the top of the air chamber. During the diving, even when the water enters the air chamber, the water is discharged out of the air chamber under exhaled air pressure generated during exhaling, so no choking in the water is suffered by a diver. If the diver cannot inhale air for two times continuously, an alarm that the diving is too deep and upward floating is required can be provided. The diver can comfortably breathe for a long time under the water with the assistance of the breathing hose with a check valve and the improved breathing nozzle.

Description

A kind of compound type rebreather simple in structure of the water that fundamentally prevents to choke

Affiliated technical field

It is the underwater breathing apparatus of source of the gas with the atmosphere that the utility model relates to a kind of, especially can fundamentally prevent scuba diver's water and simple in structure of choking, by quick replacing breathing pipe and breathe mouth and can adapt to the respirator that shallow water and deep water are breathed down respectively.

Background technology

At present, known is that the rebreather of source of the gas is breathed mouth by about 40 a centimeters hollow straight tube of a length and a common biting connecions and formed with the atmosphere.Submerged depth is limited and wayward, and water is very easy to enter respirator by straight tube and causes scuba diver's water of choking to cause safety misadventure.And related tens of kinds of rebreather utility models and the patent of invention of relevant patent, as the patent No. or number of patent application be: 200720126775.9, in 200620106337.1,200610023309.8 etc. the example, substantially all be provided with various forms of floating air intakes chamber and avoided water directly to enter respiration tracheae, also further being provided with outside inlet plenum of having kept away the water device, and to make water be not to enter air chamber too easily even passing through of having is provided with the water that energy such as ball float and check valve will drop into air chamber in air chamber discharge outside the air chamber.But all these inventions all can not fundamentally solve water fully and enter air chamber and then enter the problem that respiration tracheae causes the water of choking again.Particularly under extreme case, when whole air chamber accident there is not in the entry, both having made is to have in the air chamber of labyrinth to have in the example of ball float and single slope drainage valve, can not in time fully discharge water inlet, still has part water and enters respiration tracheae and cause scuba diver's water of choking.

Breathing mouth as a respirator part, common form is the mouth and the interlock of breathing mouth by the scuba diver, the scuba diver breathes through mouth thus, inconsistent with the breathing of human body per os nasal respiration under normal circumstances custom, and after the time grown, the oral cavity can feel that drying feels bad, problem is also little in shoal short time respiratory, if but in deep water, breathe by this common breathing mouth for a long time, human body will feel sick, and then has influence on the operation of scuba diver in water.

Summary of the invention

In order fundamentally to solve existing rebreather water inlet and then to cause the choke problem of water of scuba diver, the present utility model is through the ingenious design to air chamber, except making water enter the air chamber not too easily, the expiration air pressure that utilizes scuba diver itself never to rest to go round and begin again by unique design also, the water that enters air chamber once in a while in time discharged water outside the air chamber before also not entering breathing pipe once entering air chamber at water, so fundamentally got rid of the choke possibility of water of scuba diver.Both made under whole air chamber does not have extreme case in the entry, because the unique design of air chamber also only can cause the scuba diver can not breathe air continuously, the water that can't cause choking takes place.On the contrary, when the scuba diver is double when also cannot breathe air, it is dark to illustrate that the scuba diver slipped into, and air chamber has not had in the entry, and the scuba diver has in time been sent caution, should in time float.This alarm function also is an important safety advantage of the present invention.

In order to solve dry and the unused problem of long-time mouth breathing that common breathing mouth causes in the process that the scuba diver breathes for a long time in deep water, the utility model also provides a kind of breathing mouth of improvement, make the scuba diver can be as breathing with mouth and nose under the normal circumstances in breathing under long deep water, that has avoided that simple mouth breathing causes be uncomfortable.

The technical scheme that its technical matters that solves the utility model adopts is: about 50 centimeters water wing 1 middle part of diameter has the about 8 centimeters circular hole of diameter after inflation, to support air chamber 2, only heart place opens the about 2.5 centimeters hole of a diameter and passes for respiration tracheae 11 therein with the materials sealing of water wing homogeneity in water wing bottom 6.The height of inflation back water wing is controlled at about 10 centimeters.Settle air chamber 2 in the water wing center.The structure of air chamber is such: air chamber is about 8 centimeters an of diameter, and height is about 15 centimeters cylindrical plastic bottle, and the volume of air chamber is about 750 milliliters.The air chamber top ridges becomes semisphere, around the lower edge of top, have about 5 millimeters 6-12 (the best the is 10) induction openings 3 that are symmetrical distribution of diameter, connecting this induction opening has the hollow plastics breathing tubule 7 of the same diameter of equivalent amount to pass to the air chamber bottom, breathe tubule about 45 degree that behind induction opening, are inclined upwardly and be bent downwardly again, can make water can not enter air chamber easily like this to the air chamber bottom.In the middle of the air chamber is the breathing pipe 11 of 2 centimeters of diameters, this breathing pipe passes from air chamber bottom centre, the air chamber top is touched in the upper end, have 4-8 about 8 millimeters holes 10 of (the best is 6) diameter in breathing pipe upper end near symmetry around the port, the air in the air chamber enters breathing pipe through aperture herein.Breathing pipe passes the air chamber bottom and leads to outside the air chamber, is connected to through ripple breathing hose 4 and breathes mouth 5.

The breathing mouth (Fig. 3) of improvement is achieved in that breathing mouth 5 front portions at common biting connecions is provided with a three-way pipe 12, the intermediate conduit 13 of three-way pipe is connected together by the about 6 centimeters corrugated flexible hose of the about 1.5 centimeters length of a diameter and the nose position of common divemask, and the pipeline on three-way pipe both sides is the air inlet pipe 14 and the freeing pipe 15 of connecting band check valve respectively.The scuba diver just can be as having breathed with mouth and nose under the normal circumstances like this.

In shallow water, the breathing pipe that passes air chamber links to each other just passable through a corrugated flexible hose and common biting connecions breathing mouth.But in deep water, consider that the time in scuba diver's resident water is longer, and because corrugated hose is longer in deep water, the air of retaining in the pipeline is more, therefore be necessary to be replaced by the breathing mouth of improvement with breathing mouth, add a threeway 19 in the breathing pipe and the junction of two corrugated flexible hoses and be connected just passable connecting two corrugated flexible hoses that intake and exhaust that respiration tracheae and the corrugated flexible hose of breathing mouth change band check valve (Fig. 4) into separate, at this moment needing only.Certainly, consider that the hydraulic pressure in the deep water increases, at this moment connect the corrugated flexible hose that the corrugated flexible hose of usefulness is preferably reinforced through steel wire.In addition, the check valve of indication (Fig. 4) can be arranged on position as shown in Figure 3 herein, realizes by the form of inserting a lightweight rubber sphere 21 in 6 centimeters left and right sides diameters of two segment lengths about 2 centimeters and the

unequal pipe

20,23 of two ends internal diameter.

The beneficial effects of the utility model are, have fundamentally solved scuba diver's safety problem of water of choking when respiration, and mix the breathing mouth of improvement, can allow scuba diver safety and comfort ground in deep water breathe.The utility model will make the beginning swimmer overcome fear to water, grasp the technical ability that swims in the water quickly, and can not allow the harm of choking in tracheae and the lung of unclean water healthy in the process of learn swim again.In addition, the utility model is simple in structure, also has alarm function when scuba diver's dive surpasses safe range, is easy to carry after the decomposition, will become the good security tool of amusement and under-water operation in the water.

The specific embodiment

Embodiment one shallow water respirator

As shown in Figure 2, stud with air chamber 2 at inflation water wing 1 middle part, 6 centers, water wing bottom have the about 2.5 centimeters holes of diameter to be passed through for respiration tracheae 11, and air chamber is breathed tubule 7 K/UP certain angles behind air chamber port 3 and breathed tubule and lead to the air chamber bottom so that water is difficult for entering air chamber.When the scuba diver was air-breathing in water, air entered breathing tubule 7 through air chamber port 3 and enters the air chamber inner chamber, enters respiration tracheae 11 through respiration tracheae port 10 then, led to through breathing hose and breathed mouth 5.When the scuba diver exhaled, the waste gas of exhalation was discharged outside the air chamber by the same path backward of air inlet.When air chamber integral body there is not in the entry, to only have water when the diver is air-breathing and enter air chamber, because the each tolerance of breathing of adult is about 500 milliliters, at this moment the water yield that enters air chamber also is about 500 milliliters, less than 750 milliliters of the capacity of air chamber, so both made enter air chamber whole be water also not further the respiration tracheae port 10 through the air chamber top enter respiration tracheae 11 and the water that causes choking takes place, and the water that enters air chamber can converge in the air chamber bottom, close and breathe tubule bottom porting 8, make air chamber be air-tight state, in the ensuing exhalation process of scuba diver, under the expiration pressure by air pressure, the water that enters air chamber will be discharged outside the air chamber through breathing tubule 7.That is to say to enter how much water of air chamber when air-breathing, also can discharge how much water when exhaling, the water problems of can not choking is exactly that the scuba diver cannot breathe air at the most.Opposite illustrate that when the scuba diver is double when cannot breathe air scuba diver's dive is dark excessively, air chamber has not had in the entry, and the caution scuba diver should float as early as possible, avoids the danger generation.

Embodiment two deep water respirators

Because of scuba diver's residence time in deep water long, and deep water hydraulic pressure is big, at this moment common biting connecions should be breathed mouth 5 and be replaced by Improvement type and breathe mouth (Fig. 3), breathing hose is replaced by the corrugated flexible hose that steel wire supports.When the scuba diver was air-breathing, the air that the respiration tracheae 11 in air chamber comes out entered ripple air induction hose 17 through threeway 19, enters check valve 16 again.At this moment check valve is opened at air inlet air pressure lower inlet duct 20, and freeing pipe 23 sealings are so air admission air inlet pipe 14 is breathed for diver's mouth and nose.During expiration, the waste gas that mouth and nose are breathed out enters check valve 16 through freeing pipe 15, and under expiration air pressure, check valve air inlet pipe 20 seals equally, and freeing pipe 23 is opened, and waste gas enters ripple exhaust hose 20, enters respiration tracheae through threeway 19, again outside air chamber is discharged air chamber.Because intake and exhaust separate, and add the breathing mouth of improvement, scuba diver's the effciency of respiratory will be improved, and help the underwater long working of scuba diver.
