DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The core of the utility model is to provide a high and low oxygen training system. The flow control valve and the oxygen concentration sensor realize closed-loop control of the oxygen concentration of the output gas, and realize precise regulation of low oxygen concentration and high oxygen concentration.

[0025] The high and low oxygen training system provided by the utility model includes an air compressor 101, a heat exchanger 103, a filtering device, an air separation device 108, an air storage bag 110 and an exhalation valve assembly 111 connected to a breathing mask, which are connected in sequence. A flow control valve 109 is provided between the air separation device 108 and the air storage bag 110. The exhalation valve assembly 111 is provided with an oxygen concentration sensor 112 for detecting the real-time oxygen concentration in the exhalation valve assembly 111. The oxygen concentration sensor 112 is connected to the flow control valve 109 signal so as to send the measured real-time oxygen concentration to the flow control valve 109. The flow control valve 109 is used for the oxygen flow and nitrogen flow entering the air storage bag 110.

[0026] The air compressor 101 is used to pressurize the ambient gas entering the air compressor 101; the heat exchanger 103 is used to cool the pressurized gas to make it into normal temperature high pressure gas; the filtering device is used to filter the moisture, impurities, bacteria and odor in the gas;

[0027] The air separation equipment 108 uses a polymer membrane to separate oxygen and nitrogen in the gas through a membrane separation method to obtain oxygen-rich gas and nitrogen-rich gas. Figure 4 O2 in nitrogen-rich gas, i.e. Figure 4 N2 in;

[0028] The two air inlets of the flow control valve 109 are respectively connected to the oxygen-rich gas outlet and the nitrogen-rich gas outlet of the air separation device 108, and the air outlet is connected to the air inlet of the air storage bag 110, and the air inlet flow rates of the two air inlets of the flow control valve 109 can be adjusted, so the flow control valve 109 can adjust the oxygen flow rate and the nitrogen flow rate entering the air storage bag 110;

[0029] The air storage bag 110 is used to temporarily store and mix oxygen-rich gas and nitrogen-rich gas. The oxygen-rich gas and nitrogen-rich gas are diffused and mixed in the air storage bag 110 so that the gas components in the air storage bag 110 are balanced; the mixed gas enters the exhalation valve assembly 111 through the air outlet of the air storage bag 110, and is finally connected to the breathing mask through the mask interface 118.

[0030] In order to accurately control the oxygen concentration of the output gas, the exhalation valve assembly 111 is provided with an oxygen concentration sensor 112, which is used to detect the real-time oxygen concentration of the gas in the exhalation valve assembly 111, that is, to detect the real-time oxygen concentration of the output gas; the oxygen concentration sensor 112 is used to form a closed-loop control with the flow control valve 109 to ensure that the oxygen concentration of the output gas is the same as the preset oxygen concentration.

[0031] It should be noted that the preset oxygen concentration generally includes two preset values ​​of a preset low oxygen concentration and a preset high oxygen concentration, which correspond to two different working conditions of low oxygen breathing and high oxygen exhalation, respectively.

[0032] Taking hyperoxia breathing as an example, when the real-time oxygen concentration measured by the oxygen concentration sensor 112 is lower than the preset hyperoxia concentration, the flow control valve 109 controls the flow of the oxygen-rich gas inlet to increase and the flow of the nitrogen-rich gas inlet to decrease, so as to increase the oxygen flow entering the air storage bag 110 and reduce the nitrogen flow entering the air storage bag 110;

[0033] On the contrary, when the oxygen concentration sensor 112 measures a real-time oxygen concentration higher than the preset high oxygen concentration, the flow control valve 109 controls the flow of the oxygen-rich gas inlet to increase and the flow of the nitrogen-rich gas inlet to decrease, so as to reduce the oxygen flow entering the air storage bag 110 and increase the nitrogen flow entering the air storage bag 110.

[0034] In order to ensure the opening adjustment accuracy of the two inlets of the flow control valve 109, the flow control valve 109 is usually set as an electrically controlled valve, and the electrically controlled valve is connected to the control board 117 by signal. The control board 117 is used to receive the measurement signal of the oxygen concentration sensor 112, determine the opening change of the flow control valve 109 according to the difference between the measured real-time oxygen concentration and the preset oxygen concentration, and output a corresponding adjustment signal to the flow control valve 109.

[0035] In order to prevent the gas pressure discharged from the exhalation valve assembly 111 from being too high and causing discomfort to the user, the exhalation valve assembly 111 is provided with a pressure relief valve 1111. The pressure relief valve 1111 can be set as a mechanical valve or an electric control valve. When the air pressure in the exhalation valve is greater than a preset air pressure value (usually atmospheric pressure), the pressure relief valve 1111 is turned on to discharge part of the gas in the exhalation valve assembly 111 into the

[0036] In this embodiment, the flow control valve 109 and the oxygen concentration sensor 112 realize closed-loop control, and can adjust the oxygen flow and nitrogen flow entering the air storage bag 110 according to the real-time oxygen concentration in the exhalation valve assembly 111, thereby adjusting the oxygen concentration of the gas in the air storage bag 110, that is, adjusting the oxygen concentration of the gas output by the exhalation valve assembly 111, thereby realizing precise adjustment of low oxygen concentration and high oxygen concentration, and having stronger adaptability.

[0037] On the basis of the above-mentioned embodiment, the structure of the filtering device is defined, and the filtering device includes a first filter 104 for removing impurities and moisture in the gas and a second filter 107 for removing bacteria and odor in the gas.

[0038] The first filter 104 is used for removing water and impurities from the gas, and the second filter 107 is used for removing bacteria and odor from the gas. The second filter 107 is usually set as a three-stage filter, with a dust removal accuracy of up to 0.01μm and an oil removal accuracy of up to 0.003mg / m³;

[0039] The specific types, models and filtering accuracy of the two are determined according to the size of the shell 1 in actual production, the input gas requirements of the air separation equipment 108, etc., and will not be repeated here.

[0040] Considering that the high and low oxygen training systems are mostly used in indoor environments, it is inconvenient to directly discharge the moisture generated by the first filter 104 through a drain pipe. An atomizer 105 can also be provided. The water outlet of the first filter 104 is connected to the inlet of the atomizer 105. The atomizer 105 is used to atomize the moisture generated by gas filtration, and the moisture can be directly discharged into the external environment after atomization.

[0041] Of course, the outlet of the nebulizer 105 may also be connected to the mask interface 118, and the gas discharged from the exhalation valve assembly 111 may be humidified by using the atomized water vapor.

[0042] When the high and low oxygen training system is not working, the mask interface 118 is connected to the external environment. In order to prevent the external air from contaminating the exhalation valve assembly 111 and the air storage bag 110, preferably, the outlet pipeline of the exhalation valve assembly 111 can be provided with a third filter 113. The third filter 113 is used to prevent impurities and bacteria in the external air from entering the exhalation valve assembly 111, thereby ensuring the cleanliness and hygiene of the gas discharged from the exhalation valve assembly 111 and protecting the health of the user.
