Embodiment Construction
[0046] In the prior art, there is no non-underwater test method and equipment for various types of diving respirators, and there is no corresponding breathing power simulation device and oxygen consumption device suitable for testing diving respirators. device, and there is no better testing method for breathing resistance.
[0047] For this reason, the present invention provides a kind of underwater breathing simulation device and underwater breathing simulation method thereof, described underwater breathing simulation device divides the breathing process of human body into two main processes, one is inhalation and exhalation The other is the oxygen consumption process. Correspondingly, the present invention makes the underwater breathing simulation device include a gas pumping device for pumping gas, so as to realize the simulation of human inhalation and exhalation, and make the underwater breathing simulation The device includes an oxygen consumption device to realize the ...

An underwater breathing simulation device and an underwater breathing simulation method thereof are disclosed. The underwater breathing simulation device comprises a pressure chamber, a gas pumping and discharging device which is disposed in the pressure chamber and used for pumping breathing gas from a gas source and discharging the breathing gas to simulate the breathing-in and breathing-out actions of the human body, and an oxygen consuming device which is disposed in the pressure chamber and used for consuming at least part of oxygen in the breathing gas to simulate oxygen consumption of the human body. The gas input end of the gas pumping and discharging device is connected to the gas source, and the gas output end of the gas pumping and discharging device is connected to the gas input end of the oxygen consuming device. With the underwater breathing simulation device, unmanned test of a diving breathing apparatus is realized, and a diving breathing apparatus can be tested more safely and quickly.
Description
technical field [0001] The invention relates to the field of diving equipment, in particular to an underwater breathing simulation device and an underwater breathing simulation method thereof. Background technique [0002] The traditional diving respirator consists of an oxygen cylinder, a primary pressure reducing valve, a secondary pressure reducing valve and a mouthpiece, commonly known as "scuba". Diving rebreathers can be divided into different types such as open rebreathers, semi-closed rebreathers and closed rebreathers. [0003] The breathing resistance of the diving rebreather is one of the main reasons for the diver's load to increase during the dive. Generally, divers rely on changing breathing intensity and mode underwater to adapt to changes in breathing resistance to ensure breathing flow. Breathing resistance is also an important evaluation index for evaluating diving respirators. Diving respirator is a personal underwater breathing protection device, and i...
