Description

Technical Field

[0001] The utility model belongs to the technical field of underwater breathing apparatus, and in particular relates to an automatically adjustable underwater breathing apparatus. Background Art

[0002] Underwater breathing apparatus is a machine that allows people to breathe underwater. Existing underwater breathing apparatuses are classified according to their functions, mainly into positive pressure air breathing apparatus, mobile oxygen breathing apparatus, long tube air breathing apparatus, positive pressure oxygen breathing apparatus, positive pressure air breathing apparatus. However, the air supply methods of these breathing apparatuses are all the same.

[0003] Existing underwater breathing apparatus generally includes a mouthpiece, a gas cylinder, an air guide tube and a pressure reducing valve. When people use it, they carry the gas cylinder on their backs and then put the mouthpiece into their mouths, so that the oxygen inside the gas cylinder passes through the pressure reducing valve to reduce the pressure, so that the gas enters the mouthpiece to provide oxygen. However, this method easily causes a waste of oxygen and cannot automatically adjust the discharge of oxygen, resulting in a short use time of the gas cylinder.

[0004] For example, an automatically adjustable underwater breathing apparatus described in the authorization announcement number CN104015898B controls the air supply according to the user's breathing frequency and gas flow rate. When the user breathes, the secondary decompression device of the apparatus adjusts the air intake according to the amount of exhaled air. The apparatus is highly convenient and safe for underwater operations, especially for beginners, as it can reduce oxygen consumption and avoid discomfort to the user when going into the water for the first time.

[0005] However, water pressure varies in waters of different depths. The spring inside the existing underwater breathing apparatus may be damaged by the change in water pressure. When the spring is not elastic enough or is severely damaged, it will lead to insufficient oxygen supply, threatening the life safety of the user.

[0006] To this end, we have proposed an automatically adjustable underwater breathing apparatus, which can control the oxygen supply according to human breathing, thereby increasing the usage time. At the same time, when the device is damaged, it can provide a backup plan to ensure continuous oxygen supply, thereby increasing the safety factor. Utility Model Content

[0007] The purpose of the utility model is to provide an automatically adjustable underwater breathing apparatus, which can control the oxygen supply according to human breathing, thereby increasing the use time, and can provide a backup plan to ensure continuous oxygen supply when the apparatus is damaged, thereby increasing the safety factor.

[0011] The conical exhaust pipe is wide at the top and narrow at the bottom. A second elastic component is arranged inside the conical exhaust pipe. A second conical piston matching the conical exhaust pipe is arranged on the second elastic component. A third magnetic block is arranged on the second conical piston. A second rotating component is threadedly arranged on the conical exhaust pipe. A fourth magnetic block attracted to the third magnetic block is arranged on the second rotating component.

[0016] Furthermore, an elastic band is provided on the hollow disk.

[0017] The technical effects achieved by this utility model are:

[0018] 1. Then oxygen is provided through the gas cylinder. At this time, the pressure between the gas cylinder and the first elastic component and the second elastic component tends to be balanced.

[0028] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0029] like Figure 1-6 As shown, the technical solution adopted by the utility model is specifically as follows: an automatically adjustable underwater breathing apparatus, comprising a gas cylinder 1, an air guide tube 2 and a mouthpiece 3, the gas cylinder 1 is connected to the air guide tube 2, a hollow disk 4 connected thereto is installed on one side of the mouthpiece 3, a conical air inlet pipe 5 and a conical exhaust pipe 6 connected thereto are arranged on the side of the hollow disk 4 away from the mouthpiece 3, and the conical air inlet pipe 5 is connected thereto and connected to the air guide tube 2;

[0030] The conical air inlet pipe 5 is wide at the top and narrow at the bottom. A first elastic component is arranged inside the conical air inlet pipe 5. A first conical piston 14 matching the conical air inlet pipe 5 is arranged on the first elastic component. A first magnetic block 7 is arranged on the first conical piston 14. A first rotating component is threadedly arranged on the conical air inlet pipe 5. A second magnetic block 8 repelling the first magnetic block 7 is arranged on the first rotating component.

[0031] The conical exhaust pipe 6 is wide at the top and narrow at the bottom. A second elastic component is arranged inside the conical exhaust pipe 6. A second conical piston 9 matching the conical exhaust pipe 6 is arranged on the second elastic component. A third magnetic block 10 is arranged on the second conical piston 9. A second rotating component is threadedly arranged on the conical exhaust pipe 6. A fourth magnetic block 11 attracted to the third magnetic block 10 is arranged on the second rotating component.

[0032] Its working principle is as follows: first, people put the mouthpiece 3 into their mouths, and then oxygen is supplied through the gas cylinder 1. At this time, the pressure between the gas cylinder 1 and the first elastic component and the second elastic component tends to be balanced. Then, when people inhale through the mouthpiece 3, suction is generated, and the suction drives the first conical piston 14 to move the first elastic component upward, thereby opening the conical air inlet pipe 5. At the same time, the suction drives the second conical piston 9 to move upward, thereby sealing the conical exhaust pipe 6. At this time, the oxygen inside the gas cylinder 1 enters the hollow disk 4 through the air guide pipe 2, so that oxygen enters the mouthpiece 3 to supply oxygen to people. When people exhale, thrust is generated, and the thrust drives the first conical piston 14 to move the first elastic component downward, thereby sealing the conical air inlet pipe 5. At the same time, the thrust drives the second conical piston 9 to The second elastic component is moved downward, so that the conical exhaust pipe 6 is opened to discharge the gas. In the prior art, the pressure in waters of different depths is different, which causes the internal first elastic component and the second elastic component to be damaged. If the damage is serious, the oxygen supply is insufficient, which will threaten life safety. If the first elastic component and the second elastic component are damaged, the first rotating component is moved on the conical air inlet pipe 5, so that the first magnetic block 7 and the second magnetic block 8 repel each other, so that the first conical piston 14 is moved, so that the conical air inlet pipe 5 is opened, so that oxygen is supplied normally. At the same time, the second rotating component is moved on the conical exhaust pipe 6, so that the third magnetic block 10 and the fourth magnetic block 11 attract each other, so that the second conical piston 9 is moved, so that the conical exhaust pipe 6 is opened, so that the gas is discharged normally. The device can control the oxygen supply according to human breathing, and can provide a backup plan to ensure continuous oxygen supply when the device is damaged, thereby improving the safety factor.

[0033] The utility model can be adjusted according to people's breathing frequency. When people's breathing frequency is high, the first conical piston 14 and the second conical piston 9 move in coordination, thereby achieving an automatic adjustment effect.

[0034] At the same time, in order to balance the pressure between the gas cylinder 1 and the first tapered piston 14 and the second tapered piston 9, a pressure reducing valve is provided on the air duct 2. The pressure reducing valve can reduce the pressure of the gas cylinder 1 so that it can be parallel to the elastic force of the first elastic component and the second elastic component, thereby facilitating the operation of the device.

[0035] It should be noted that in the prior art, the pressure reducing valve is adjustable. When using this device, it must be adjusted so that the elastic force of the first elastic component and the second elastic component are parallel to the pressure area of ​​the gas cylinder 1 for decompression before it can be used. This is the prior art and will not be described in detail here.

[0036] An elastic band 21 is provided on the hollow disk 4, and the entire device can be fixed on people's face through the elastic band 21.

[0037] like Figure 5 As shown, the first elastic component includes a first fixed plate 12 arranged on the conical intake pipe 5, the first fixed plate 12 is opened with a first through hole, a first movable rod 13 is arranged inside the first through hole, a first limiting plate is installed on the top of the first movable rod 13, the bottom of the first movable rod 13 is connected to the first conical piston 14, and a first spring 15 is sleeved on the first movable rod 13, and the first spring 15 is located between the first limiting plate and the first conical piston 14.

[0038] When people inhale, suction is generated, causing the first conical piston 14 to drive the first movable rod 13 to move on the first fixed plate 12 to squeeze the first spring 15, thereby opening the gap in the conical air inlet pipe 5, allowing oxygen to enter the hollow disk 4 for nourishment. When people's breathing frequency increases, the movement speed of the first conical piston 14 will also increase, thereby achieving an automatic adjustment effect.

[0039] like Figure 6 As shown, the second elastic component includes a second fixed plate 16 arranged on the conical exhaust pipe 6, the second fixed plate 16 is opened with a second through hole, a second movable rod 17 is arranged inside the second through hole, a second limiting plate is installed on the top of the second movable rod 17, the bottom of the second movable rod 17 is connected to the second conical piston 9, and a second spring 18 is sleeved on the second movable rod 17, and the second spring 18 is located between the second limiting plate and the second conical piston 9.

[0040] When people inhale, suction is generated, causing the second conical piston 9 to seal the conical exhaust, thereby preventing oxygen from escaping. When people exhale, thrust is generated, causing the second conical piston 9 to drive the second movable rod 17 to move on the second fixed plate 16 to squeeze the second spring 18, thereby opening the gap in the conical exhaust pipe 6 and allowing the exhausted gas to be discharged. When people's breathing frequency increases, the movement speed of the second conical piston 9 will also increase, thereby achieving an automatic adjustment effect.

[0041] The first rotating assembly includes a first threaded hole formed on the conical air inlet pipe 5 . A first threaded rod 19 is disposed inside the first threaded hole. One end of the first threaded rod 19 is connected to the first magnetic block 7 .

[0042] By rotating the first threaded rod 19 , the first threaded rod 19 drives the first magnetic block 7 to move, so that the first magnetic block 7 moves toward the second magnetic block 8 , thereby generating a repulsive force to move the first tapered piston 14 .

[0043] In order to ensure the sealing, a first sealing sleeve is provided at the threaded connection between the first threaded rod 19 and the tapered air inlet pipe 5, so as to prevent the oxygen from being discharged.

[0044] The second rotating assembly includes a second threaded hole opened on the conical exhaust pipe 6 . A second threaded rod 20 is arranged inside the second threaded hole. One end of the second threaded rod 20 is connected to the third magnetic block 10 .

[0045] By rotating the second threaded rod 20 , the second threaded rod 20 drives the third magnetic block 10 to move, so that the third magnetic block 10 moves toward the fourth magnetic block 11 , thereby generating suction force to move the second tapered piston 9 .

[0046] The working principle of the utility model is as follows: first, people put the mouthpiece 3 into their mouths, and then oxygen is provided through the gas cylinder 1. At this time, the pressure between the gas cylinder 1 and the first elastic component and the second elastic component tends to be balanced. Then, when people inhale through the mouthpiece 3, suction is generated, and the suction drives the first conical piston 14 to move the first elastic component upward, thereby opening the conical air inlet pipe 5. At the same time, the suction drives the second conical piston 9 to move upward, thereby sealing the conical exhaust pipe 6. At this time, the oxygen inside the gas cylinder 1 enters the hollow disk 4 through the air guide pipe 2, so that oxygen enters the mouthpiece 3 to supply oxygen to people. When people exhale, thrust is generated, and the thrust drives the first conical piston 14 to move the first elastic component downward, thereby sealing the conical air inlet pipe 5. At the same time, the thrust drives the second conical piston 9 drives the second elastic component to move downward, so that the conical exhaust pipe 6 opens to discharge the gas. In the prior art, the pressure in waters of different depths is different, which causes the internal first elastic component and the second elastic component to be damaged. If the damage is serious, the oxygen supply is insufficient, which will threaten life safety. If the first elastic component and the second elastic component are damaged, the first rotating component moves on the conical air inlet pipe 5, so that the first magnetic block 7 and the second magnetic block 8 repel each other, so that the first conical piston 14 moves, so that the conical air inlet pipe 5 opens, so that oxygen is supplied normally. At the same time, the second rotating component moves on the conical exhaust pipe 6, so that the third magnetic block 10 and the fourth magnetic block 11 attract each other, so that the second conical piston 9 moves, so that the conical exhaust pipe 6 opens, so that the gas is discharged normally. The device can control the oxygen supply according to human breathing, and can provide a backup plan to ensure continuous oxygen supply when the device is damaged, thereby improving the safety factor.

[0047] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
