[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a diving device, and more particularly to a diving device that can prevent breathing caused by breathing performed by a wearer in water from being released into the water.
[0002]
[Prior art]
Conventionally, diving equipment can be roughly classified into helmet diving equipment, hooker diving equipment, and scuba diving equipment.
The helmet diving device sends air from an air supply source such as a compressor above the water into the helmet of the wearer (diver) who is underwater with an air supply tube, and the wearer breathes with the sent air, and The air is a diving device designed to circulate in the diving garment, and buoyancy and other merits due to the air stored in the diving garment can be obtained. On the other hand, there are problems such as poor mobility and time-consuming learning.
The Hooker diving device supplies air from an air supply source such as a compressor on the water with an air supply tube, and secondarily adjusts the pressure to the pressure of the diving depth with a terminal regulator (pressure regulator). The diving device is designed to supply air to the wearer, and has the advantages of better mobility and less air consumption than the helmet diving device.
The scuba diving equipment is sold under the trade name of Aqualung. Carry an air cylinder, supply air with an air supply tube from the cylinder, and perform secondary adjustment to the pressure of the diving depth with a regulator. This is a diving device that supplies breathing air to the wearer, and since it carries an air cylinder that is an air supply source, there is a merit that is very mobile and flexible, but the amount of air is limited There was a problem.
[0003]
FIG. 7 shows an example of a conventional hooker diving device. 1 is a regulator and 2 is an air supply tube. Reference numeral 3 denotes a full face mask. Air supplied from an air supply source such as a compressor on the water (not shown) is sent into the regulator 1, the pressure is secondarily adjusted, and the pressure is adjusted to the depth of the diving and used for the breathing of the wearer. The air in the regulator 1 communicates with the full face mask 3 and is inhaled into the body by the inhalation operation of the wearer. On the other hand, exhaled air exhausted by the wearer's breathing is released from a part of the regulator 1 in the form of bubbles 4 into the water.
[0004]
[Problems to be solved by the invention]
By the way, each of the above-mentioned types of diving equipment has a feature in the air supply method. On the other hand, for exhaust, exhaled air exhausted by the wearer (diver) in breathing underwater is released into the water as it is. Had been deceived.
However, recently, for example, in water purification tanks and other water storage facilities, it has been required to reduce contamination of purified water as much as possible. In such a facility, the work in the water tank may be performed by an underwater robot or the like, but in some cases, work by diving may be required. In such a case, of course, the diver is diving with equipment that does not cause contamination from the body, but with regard to her breathing, the exhalation is still released into the water as it is. It was. For this reason, there is a problem of contamination of water in the tank due to exhalation or hygiene.
[0005]
Therefore, the present invention solves the above-mentioned problems of conventional diving equipment, and prevents contamination of water such as purified water by preventing divers and the like from purifying water tanks and other exhaled breath performed in the water. It is an issue to provide a diving device that can be used.
[0006]
[Means for Solving the Problems]
The diving device of the present invention that solves the above problems is a regulator that adjusts the pressure by introducing air supplied from an air supply source such as a compressor disposed on the water or a portable air cylinder through the air supply tube 20. 10 , which allows the wearer P to inhale the air whose pressure has been adjusted by the regulator 10 , in order to discharge the exhaled air exhausted by the wearer P to the regulator 10. of the exhaust port 12 provided with, is detachably connected to the exhaust port 12 is provided an exhaust tube 40 which can reach up water, and the exhaust control valve 50 with an exhaust tube 40 provided with an exhaust control valve 50 A pressure-sensitive expansion / contraction tube 51 and a pair of connecting portions 52, 53 are provided. The pressure-sensitive expansion / contraction tube 51 receives water pressure from the surroundings and is regulated. When the air pressure in the air chamber 13 of the regulator 10 is lower than the external water pressure, the pressure is the same as the external water pressure. In the case where there is a vent, the air vents 52a, 53a of either or both of the connecting parts 52, 53 of the exhaust control valve 50 are sealed to block the exhaust passage, and the air pressure in the air chamber 13 of the regulator 10 is reduced. When the pressure rises outside the external water pressure, the vent holes 52a and 53a of the connection portions 52 and 53 of the exhaust control valve 50 are released to open the entire exhaust passage of the exhaust tube 40.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be further described with reference to the following drawings.
1 to 4 show a first embodiment of the present invention, FIG. 1 is a schematic configuration diagram of a diving device, FIG. 2 is a longitudinal sectional view of a main part of the diving device, and FIG. 3 is a horizontal view of a main portion of the diving device. FIG. 4 is an explanatory view of the exhaust control valve. FIG. 5 is a schematic configuration diagram showing a second embodiment of the present invention, and FIG. 6 is a cross-sectional configuration diagram of a main part showing a third embodiment of the present invention.
[0008]
First, a first embodiment of the diving tool of the present invention will be described with reference to FIGS.
10 is a regulator, 20 is an air supply tube, 30 is a full face mask, and 40 is an exhaust tube. Reference numeral 50 denotes an exhaust control valve provided in the exhaust tube 40.
[0009]
The regulator 10 is provided with an air introduction port 11 for introducing air sent through the air supply tube 20 and an exhaust port 12 for discharging the exhalation of the wearer P. The air supply tube 20 is detachably connected to the air inlet 11. The exhaust tube 40 is detachably connected to the exhaust port 12.
The air supply tube 20 extends to the surface of the water and is connected to an air supply source such as a compressor (not shown) disposed on the water.
The exhaust tube 40 is composed of an exhaust tube 41 on the regulator 10 side and an exhaust tube 42 on the end side through the exhaust control valve 50 in the middle, and is extended to the surface as a whole. It is possible to carry exhaled air to the water. However, simply extending the exhaust tube 40 to the water causes a problem, and it becomes impossible to ensure that the wearer P who is in the water can breathe without any trouble.
[0010]
An air chamber 13 is provided in the regulator 10, and the air introduction port 11 and the exhaust port 12 communicate with the air chamber 13 from the left and right. The air chamber 13 is in contact with the outside through a diaphragm 14.
The diaphragm 14 is subjected to water pressure from the outside in water.
A pressure hole 15a and a bulging stop wall 15b are provided in the outer shell 15 on the front side of the diaphragm 14, that is, on the side opposite to the air chamber 13, and water pressure from the outside world is provided through the pressure hole 15a. The diaphragm 14 is added. On the other hand, the bulging stop wall 15b prevents the diaphragm 14 from bulging outward (in the direction in which the space inside the air chamber 13 becomes larger).
The outer shell 15 portion on the front side of the diaphragm 14 can be removed using this as a lid. In this case, the pressure hole 15a and the bulging stop wall 15b are integrally formed in the lid.
The diaphragm 14 can be detachably attached with the lid removed.
[0011]
An air supply control valve 16 is provided at the air introduction port 11 of the regulator 10, and a tip portion of a pressure receiving lot 16 a of the air supply control valve 16 is provided in a state of facing the diaphragm 14. The air supply control valve 16 is normally provided with a spring bias in a direction to close the air inlet 11. When the air pressure in the air chamber 13 and the water pressure in the outside world are balanced (balanced) with the diaphragm 14 as a boundary, the pressure receiving lot 16a is in a state of slightly contacting the diaphragm 14, and The air inlet 11 is in a closed state. On the other hand, when the balance between the air pressure in the air chamber 13 and the external water pressure is lost and the diaphragm 14 swells to the air chamber 13 side (the air pressure in the air chamber 13 becomes lower than the external water pressure), the air The pressure receiving lot 16a is pushed by the diaphragm 14 swelled in the chamber 13, and as a result, the air supply control valve 16 opens the air inlet 11 against the spring bias. As a result, air from the air supply source is introduced into the air chamber 13 through the air supply tube 20. The introduction of air continues until the pressure inside and outside the diaphragm 14 is balanced (until the same pressure is reached). Therefore, when the wearer (diver) P breathes in water, each time the air in the air chamber 13 is inhaled, the air is replenished to the air chamber 13 through the air introduction port 11 by the inhaled amount.
[0012]
The regulator 10 is provided with a connection port 17, which is detachably connected to the connection port 31 of the full-face mask 30, thereby forming a communication path 18 between the regulator 10 and the full-face mask 30. .
[0013]
The full-face mask 30 is a mask that covers the entire face of the wearer P, and prevents water from entering the full-face mask 30 when worn. A space corresponding to at least the mouth of the wearer P of the full face mask 30 is secured as a breathing space 32. This breathing space 32 is also a voice space necessary for the wearer P to communicate with the outside.
The breathing space 32 of the full face mask 30 and the air chamber 13 of the regulator 10 are communicated with each other by the communication passage 18. Therefore, when the wearer P inhales by breathing, air is replenished from the air chamber 13 into the breathing space 32 where the pressure has dropped, and air is replenished to the air chamber 13 from the air inlet 11. Further, when the wearer P exhales by breathing, air (at least a part of the exhalation) flows from the breathing space 32 whose pressure has increased into the air chamber 13. In this case, the pressure in the air chamber 13 increases, but the air supply control valve 16 does not open. Even if the air pressure in the air chamber 13 rises from the external water pressure, the diaphragm 14 does not bulge freely outward. The reason why the diaphragm 14 bulges outward is that it is blocked by the bulge stop wall 15b.
[0014]
The exhaust control valve 50 will be described with reference to FIG. 4 shows a state in which the exhaust control valve 50 is opened, (A) is a partially sectional plan view, and (B) is a partially sectional front view.
The exhaust control valve 50 is provided in the middle of the exhaust tube 40, and includes a pressure-sensitive expansion / contraction tube 51 and a pair of connection parts 52 and 53. The pressure-sensitive expansion / contraction tube 51 is configured to be expanded and contracted by receiving a water pressure from the surroundings and receiving an atmospheric pressure from the inside of the exhaust tube 41 on the regulator 10 side. 53, the air vents 52a and 53a of either one or both are covered and sealed, and when the pressure in the air chamber 13 of the regulator 10 rises due to the exhalation of the wearer P, the pressure rises. Thus, the air vents 52a and 53a are closed and the exhaust passages of the exhaust tubes 40 including the exhaust tubes 41 and 42 are opened. Air from the regulator 10 side (exhaled air) flows through the exhaust tube 40 to the surface of the water only when the passage is opened by the exhaust control valve 50, and is released to the atmosphere.
The pressure-sensitive expansion / contraction tube 51 is used when the air pressure in the air chamber 13 is lower than the external water pressure (when the wearer P is inhaling) and when the air pressure in the air chamber 13 is balanced with the external water pressure (same as above). The pressure between the pair of vent holes 52a and 53a is cut off, and only when the air pressure in the air chamber 13 rises above the external water pressure, the air flow between the pair of vent holes 52a and 53a. A pre-adjusted one is used to ensure ventilation.
In the present embodiment, the outflow side vent 53a opposite to the regulator 10 side is always closed in a sealed state by the pressure-sensitive expansion / contraction tube 51. Here, “always” means a case other than the case where the air pressure in the air chamber 13 is higher than the water pressure.
It should be noted that the exhaust control valve 50 is preferably attached at a position close to the regulator 10 in order to ensure good operation of the exhaust control valve 50.
[0015]
As described above, by providing the exhaust control valve 50 in the exhaust tube 40, when the wearer P exhales by breathing, the exhalation can be discharged from the regulator 10 through the exhaust tube 40 onto the water. On the other hand, when the wearer P is not exhaling, the air in the regulator 10 is prevented from being discharged through the exhaust tube 51, so the wearer P performs inhalation by his / her respiration without inconvenience. be able to. When only the exhaust tube 40 is connected to the regulator 10, the air in the regulator 10 is exhausted through the exhaust tube 40 and cannot breathe.
[0016]
A second embodiment of the present invention will be described with reference to FIG. In the present embodiment, instead of the exhaust control valve 50 in the first embodiment, an exhaust control valve 60 having a slightly changed configuration is provided. The configuration other than the exhaust control valve 60 is the same as the configuration of the first embodiment, and the same members are denoted by the same reference numerals.
This exhaust control valve 60 is provided with an air chamber 63 partitioned by a diaphragm 62 from the outside in a case 61, and a receiving port 64 and an air chamber 63 for receiving exhaled air from the exhaust tube 41 on the regulator 10 side in the air chamber 63. There is provided a delivery port 65 for sending the air inside to the exhaust tube 42 on the end side. A valve body 66 is provided for opening and closing the outlet 65 of the exhaust tube 42 on the end side. The valve body 66 normally closes the delivery port 65 and receives the exhalation from the reception port 64 so that the air pressure in the air chamber 63 rises above the external water pressure, so that the diaphragm 62 expands outward. It is integrally attached to the diaphragm 62 so as to open the delivery port 65 when it comes out.
Of course, the valve body 66 does not necessarily have to be integrally attached to the diaphragm 62. In short, the valve body 66 closes the delivery port 65 in a state where the air chamber 63 and the external water pressure are balanced (same pressure), and the air enters the receiving port 64 so that the pressure balance between the inside and the outside is balanced. When the diaphragm 62 collapses and the diaphragm 62 bulges outward, the outlet 65 is opened, and when the air pressure in the air chamber 63 decreases and balances with the external water pressure, the diaphragm 62 is contracted accordingly. Then, the delivery port 65 may be closed again.
[0017]
By configuring the exhaust control valve 60 as described above, when the wearer P exhales by breathing, the exhalation enters the air chamber 13 of the regulator 10 from the full face mask 30, and thereby the exhalation amount in the air chamber 13. Air enters the exhaust control valve 60 through the exhaust tube 41 on the regulator side, whereby the diaphragm 62 expands outward, and the valve body 66 opens the delivery port 65. When the air corresponding to the expiratory volume is discharged from the air chamber 63 to the exhaust tube 42 on the end side, the valve body 66 is fed in conjunction with the diaphragm 62 when the air pressure in the air chamber 63 is balanced with the external water pressure. The outlet 65 is closed. That is, when the wearer P exhales by breathing, only the exhaled air is discharged through the exhaust tube 40 onto the water. As a result, the amount of air (air pressure) in the regulator 10 is ensured, and the wearer P can continue breathing without hindrance.
[0018]
A third embodiment of the present invention will be described with reference to FIG. In this embodiment, an exhaust control valve 70 is provided for the exhaust port 12 of the air chamber 13 of the regulator 10.
That is, a valve body 71 that springs the exhaust port 12 in the closing direction is attached to the exhaust port 12, and a connecting wire 72 that connects the valve body 71 and the diaphragm 14 is provided. The valve body 71 closes the exhaust port 12 by the spring bias when the air pressure in the air chamber 13 and the external water pressure are balanced and the diaphragm 14 is in the phantom line (two-dot chain line) in FIG. When the wearer P exhales by breathing and the diaphragm 14 swells in the direction indicated by the solid line from the virtual line, the connecting wire 72 is pulled together with the diaphragm 14, and as a result, the valve body 71 is virtual. The exhaust port 12 is opened by being moved in the direction indicated by the solid line against the spring bias from the position of the closed state indicated by the line. As a result, when the air inside the air chamber 13 is discharged and the internal and external pressures are balanced again, the tensile force due to the connecting wire 72 is lost as the diaphragm 14 contracts, and the valve body 71 pushes the exhaust port 12 with its spring biasing force. Block. As a result, when the wearer P exhales by breathing, only an amount corresponding to the exhalation amount is discharged from the regulator 10 through the exhaust tube 40 onto the water. As a result, the amount of air (air pressure) in the regulator 10 is secured, and the wearer P can continue to breathe without any trouble.
[0019]
The exhaust control valve 70 provided in the air chamber 13 of the regulator 10 is not limited to the one using the valve body 71 and the connecting wire 72 described above. The exhaust control valve 70 provided in the air chamber 13 is, in short, the case where the wearer P is inhaling by breathing and while inhaling or exhaling (whether the air pressure in the air chamber 13 is the same as the external water pressure, When the pressure is less than that, the exhaust port 12 is kept closed, and the wearer P is exhausting while breathing (when the air pressure in the air chamber 13 becomes larger than the external water pressure). What is necessary is just to set it as the structure which made the opening | mouth 12 the open state.
[0020]
In the above first to third embodiments, the full-face mask 30 is combined with the regulator 10, but at least the mouth and nose of the wearer P are watertight so that the exhalation of the wearer P is not released into the water. The face mask can be any surface mask that does not necessarily cover the entire face including the eyes.
Further, as long as a diver or the like returns all of his / her exhalation into the regulator 10, even if the mouthpiece is combined with the regulator 10 instead of using a face mask, all exhalation is not released into the water. It is also possible to carry it out and release it. In this case, the diver's self-management is required.
[0021]

The present invention has the above-described configuration and action. According to the diving device of claim 1, air supplied from an air supply source such as a compressor disposed on the water or a portable air cylinder is provided with an air supply tube. comprising a regulator that adjusts a pressure introduced through, whereby a diving instrument that to be able to suck it wearer air whose pressure is adjusted by the regulator, the wearer has discharged to the regulator In addition to providing an exhaust port for discharging exhaled air, an exhaust tube that is detachably connected to the exhaust port so as to reach the surface of the water is provided, and an exhaust control valve is provided on the exhaust tube and the exhaust control valve is sensitive. A pressure expansion / contraction tube and a pair of connecting portions are provided, and the pressure-sensitive expansion / contraction tube receives water pressure from the surroundings and air from the exhaust tube on the regulator side. When the air pressure of the air chamber of the regulator is lower than the external water pressure or when the air pressure is the same as the external water pressure, any of the connection portions of the exhaust control valve is configured. Either or both of the vents are sealed to block the ventilation of the exhaust passage, and if the air pressure in the air chamber of the regulator rises above the external water pressure, the vent of the connection part of the exhaust control valve should be sealed. Since it is configured to release and open the entire exhaust passage of the exhaust tube ,
The exhaled breath exhausted by the wearer due to breathing in the water can be discharged from the regulator through the exhaust tube to the water without being released into the water. Therefore, it is possible to prevent the purified water from being contaminated with exhaled air.
Moreover, even if the exhaust tube is connected from the regulator so as to reach the surface of the water, the exhaust control valve provided in the middle of the exhaust tube can release only the amount of exhaled air exhausted by the wearer by breathing to the water each time. Therefore, it is possible to continuously and stably secure an air amount sufficient for the wearer to breathe inside the regulator.
By providing the exhaust control valve in the exhaust tube, it is possible to avoid complication of the structure of the regulator, increase in weight, and increase in dimensions compared to the case where it is provided in the regulator or the like.
Further, according to the diving device according to claim 2, in addition to the effect by the configuration according to claim 1 , the regulator is detachable from the face mask capable of covering at least the mouth and nose of the wearer in a watertight manner. Because it is a connected structure,
Exhaled air from the mouth and nose exhausted by the wearer is surely returned to the regulator from the face mask and does not leak into the water. Of course, leakage of liquid from the mouth and nose can also be prevented.
In addition, the wearer's mouth and nose are free in the face mask, so that they can breathe freely and speak freely for communication with the outside.
