Description

Structural Improvement of Breathing Valve for Diving Circulation System

The present invention provides a structural improvement of a breathing valve for a diving circulatory system, in particular to an improved breathing valve structure for a diving circulatory system that can be freely installed with a breathing regulator and has both lightness and safety.

Press, closed-circuit rebreather (Closed-Circuit Rebreathers, CCR) is a kind of gas that can be spit out for recycling, so that the gas can be used more efficiently and prolong the diving time, and it also makes the whole diving process hardly spit out Bubble device.

The standard version of the fully enclosed rebreather will be matched with a breathing mouthpiece assembly (Diver Supply Valve, DSV), which is composed of an intake check valve, a mouthpiece, an outlet check valve, and a three-way, which is always positive pressure. Therefore, the tee must be closed with a lever before leaving the mouth, otherwise, if the water pressure is greater than the air pressure, the equipment will be damaged by water ingress. This type of CCR has no backup air source, and relatively speaking, it has greater safety concerns. Although an additional backup air source can be carried, the original mouthpiece must be unplugged when switching to use, and the mouthpiece must be tightly tied to the back of the head for replacement. It is not easy and cannot be replaced quickly, but the backup air source is for emergency use and there is no sufficient time to replace it.

The advanced version of CCR integrates the DSV with a Bail-Out Valve (BOV). BOV is a fast and safe solution that at least allows for conscious breathing and time to calm down. In an emergency, the operational load can be avoided to safely switch to the emergency release cylinder. Although this type of CCR can use the same mouthpiece to quickly switch two air sources, the mouthpiece has both DSV and BOV, which will greatly increase the weight of the mouthpiece, which will also increase the burden on the user, and the purchase cost of the advanced version of the CCR will be higher. Because the DSV and BOV have been modularized and integrated, if the burden is too large and you want to simply use the DSV, you can only purchase the standard version of the CCR, and you cannot disassemble the BOV separately.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the creators of this new model and related manufacturers in this industry are eager to research and improve.

Therefore, in view of the above-mentioned deficiencies, the creator of this new type has collected relevant information, evaluated and considered from various parties, and based on years of experience accumulated in this industry, through continuous trial production and modification, before designing this kind of freely installed breathing apparatus. Regulator, and a new patent for the improvement of the breathing valve structure for the diving circulatory system that is both lightweight and safe.

The main purpose of this new model is to detachably combine the breathing regulator with the connecting base, so that the user can freely choose the first breathing channel or the second breathing channel by switching the switch, and the need for using the breathing regulator is not required. When the connector is used alone, it can provide a lightweight diving circulation system and an advanced emergency and circulation dual-purpose system with a single component.

In order to achieve the above purpose, the main structure of the present invention includes: a connecting seat, a mouthpiece joint, a first breathing passage, a regulator joint, a breathing regulator, a docking portion, a second breathing passage, and A switch, wherein the mouthpiece joint part is arranged on one side of the connection seat, the first breathing passage is arranged on the joint seat and communicates with the mouthpiece joint part, the regulator joint part is arranged on the other side of the connection seat, the breathing adjustment The device has a docking part correspondingly combined with the regulator joint part, the second breathing channel is arranged on the respiration regulator and communicates with the mouthpiece joint part, and the switch is arranged on the connecting seat to control the mouthpiece joint part to communicate with the first mouthpiece joint part. A breathing passage or a second breathing passage.

The connection seat itself has a first breathing channel, so it can be used alone as a standard version of the CCR after being combined with the mouthpiece body, or the breathing regulator can be assembled on one side of the connection seat by using the regulator joint and the docking part according to the needs of the user. , and use the second breathing channel of the breathing regulator as an emergency breathing channel, so that it can be combined into an advanced version of the CCR. In times of crisis, just use the switch to quickly switch from the first breathing channel to the second breathing channel. It is simple, fast, and safe. If you want to use the connection seat alone due to weight considerations, it can also be disassembled freely, with a high degree of freedom.

With the above technology, the standard version of the conventional fully enclosed rebreather has high safety concerns and is not easy to replace the air source, and the advanced version of the mouthpiece has a heavy burden, high cost, and cannot be disassembled separately. BOV and other problems Breakthrough points to achieve the practical progress of the above advantages.
