Description

Technical Field

[0001] This utility model belongs to the field of diving equipment technology, and in particular relates to a closed-loop recirculating breathing diving device capable of underwater communication. Background Technology

[0002] In order to obtain marine food, early humans relied solely on holding their breath and using simple snorkels to move around in shallow waters. Later, diving bells were invented. In 1772, French scientist Philéminette designed a device that allowed people to move freely and "re-breath," which was an early attempt at a similar closed-loop respiration. In fields such as marine resource development, underwater engineering construction, and underwater equipment maintenance, divers need to work closely with surface personnel or other divers. Underwater communication can improve work efficiency and ensure operational safety.

[0003] Currently, closed breathing apparatus requires divers to undergo a very cumbersome and complex inspection and dressing process, which affects operational efficiency. It requires precise control of the oxygen content in the breathing gas. As the depth changes, the oxygen partial pressure will change. If not controlled properly, hyperxemia or hypoxia may occur, endangering the diver's life. Utility Model Content

[0004] In response to the above situation, in order to overcome the shortcomings of existing technologies such as cumbersome wearing and difficulty in controlling the oxygen content of breath gases.

[0005] The technical solution adopted by this utility model is as follows: a closed-loop recirculating breathing diving suit for underwater communication, including a front chest and a back, with a shoulder strap between the front chest and the back, and a storage component located at the outer end of the front chest, the storage component being used to facilitate the storage and wearing of the equipment and the placement of the communication module; it also includes a breathing system located on the outer side of the back, the breathing system being used to realize the internal circulation operation of breathing and control the oxygen content of the breathing gas.

[0006] Furthermore, the storage assembly includes a support layer and a sealing pocket. The upper inner side of the support layer is sewn to the front chest. The lower outer side of the front chest is provided with Velcro 1. The lower inner side of the support layer is provided with Velcro 2 that matches Velcro 1. Auxiliary straps are symmetrically provided at both ends of the front chest and back. One end of the auxiliary strap near the front chest is provided with Velcro 3 that matches Velcro 1. The sealing pocket is sewn to the outside of the support layer. The sealing pocket contains a battery pack and a control unit.

[0007] Furthermore, the respiratory system includes a body, a partition, filter plates, and a ring shell. The body is sewn to the outer back, and the partition is fixed inside the body, dividing the interior of the body into a return air chamber, an adsorption chamber, a mixing chamber, a placement chamber, and a storage chamber. Several filter plates are spaced apart inside the adsorption chamber. The ring shell is fixed inside the channel between the adsorption chamber and the mixing chamber. The ring shell has a closed pressurization chamber inside, with an exhaust port on one side of the mixing chamber. One end of the pressurization chamber is connected to the outlet of a turbine air pump via a conduit. A one-way valve unit is provided in the channel between the return air chamber and the adsorption chamber. A one-way valve unit is provided in the channel between the mixing chamber and the storage chamber. A one-way valve unit is provided in the channel between the placement chamber and the mixing chamber. An oxygen module is installed in the placement chamber. An exhaust port and an exhaust port are respectively provided on the outer sides of the storage chamber and the return air chamber. A respiratory module is connected between the exhaust port and the exhaust port.

[0008] Furthermore, the spaces between the filter plates are filled with carbon dioxide adsorbent.

[0009] Furthermore, the battery pack is electrically connected to the control unit via wires.

[0010] Furthermore, the breathing module includes a support tube, a slider, an adjusting rod, and a mouthpiece. The support tube is located on the front side of the chest, and its sides are connected to an air outlet and an air return port via flexible tubes. The slider is slidably disposed inside the support tube. The adjusting rod is threaded to one end of the support tube, and the mouthpiece is fixed to the other end of the support tube. A spring is provided between the adjusting rod and the slider, and a second spring is provided between the slider and the inside of the support tube.

[0011] Furthermore, the support tube has a through hole one and a through hole two on its side, and the slider has a through hole three connected to the through hole one and a through hole four connected to the through hole two, respectively.

[0012] Furthermore, spring one and spring two are disposed inside the support tube. One end of spring one is in contact with the adjusting rod, and the other end of spring one is in contact with the slider. One end of spring two is in contact with the slider, and spring two is in contact with the support tube.

[0013] Furthermore, the slider is equipped with a radio module, which is electrically connected to the control unit via wires. The battery pack is electrically connected to the control unit via wires, and the turbine air pump is electrically connected to the control unit via wires.

[0014] The beneficial effects of this utility model after adopting the above structure are as follows:

[0015] (1) The combination of the support layer and sealed pocket in the front chest and back with the shoulder strap and storage components facilitates the storage and wearing of equipment and the placement of communication modules, thereby improving work efficiency.

[0016] (2) By linking the multi-chamber system with the turbine pump, one-way valve and adjustable breathing module, the mixing efficiency of the mixed gas in the breathing gas is improved, and the oxygen content in the breathing gas needs to be precisely controlled to regulate the breathing force in the breathing module.
