Optionally, when the target oxygen concentration of the current mixed gas is high oxygen concentration, the mixed gas can be prepared by mixing oxygen and control, at this time, the opening and closing piece corresponding to the nitrogen-rich gas inlet 213 is adjusted to be communicated with the outside air, the nitrogen-rich gas is directly discharged into the outside air, and the flow ratio of the oxygen and the air can be calculated according to the target oxygen concentration, the oxygen concentration of the oxygen and the oxygen concentration of the air; and the total flow of the gas is calculated according to the gas pressure of the mixed gas, the target flow of the oxygen and the air can be obtained according to the flow ratio of the oxygen and the air and the total flow of the gas, the flow of the oxygen and the air is adjusted to the corresponding target flow by controlling the opening degree of the opening and closing piece corresponding to the oxygen inlet 212 and the second air, and the pressure of the system is adjusted by adjusting the opening degree of the gas pressure adjusting valve 170. When the current target oxygen concentration is low oxygen concentration, the mixed gas can be obtained by mixing the nitrogen-rich gas and the air, at the moment, the corresponding opening and closing piece of the oxygen inlet 212 is closed, and the flow ratio of the nitrogen-rich gas and the air can be obtained through calculation according to the target oxygen concentration, the oxygen concentration of the nitrogen-rich gas and the oxygen concentration of the air; and the total flow of the gas is calculated according to the pressure of the mixed gas, the target flow of the nitrogen-rich gas and the air can be obtained according to the flow ratio of the nitrogen-rich gas and the air and the total flow of the gas, and the flow of the nitrogen-rich gas and the air is adjusted to the corresponding target flow by controlling the opening degree of the opening and closing piece corresponding to the nitrogen-rich gas inlet 213 and the second air inlet 211. Meanwhile, the oxygen concentration and the air pressure of the mixed gas are detected in real time, and the opening and closing piece is adjusted according to the difference between the detected oxygen concentration and the target oxygen concentration and the difference between the detected air pressure and the target air pressure.
For example, the gas treated by the second air purification device 160 is air, the oxygen content is about 21%, and the evolved air can enter the gas mixing valve 210 through the second air inlet 221; the oxygen content of the oxygen-enriched gas prepared by the oxygen preparation device 110 is 85-90 percent, and the oxygen content of the nitrogen-enriched gas is 10-15 percent. The oxygen-enriched gas with the oxygen content of 85-90% enters the oxygen storage device 400, and the oxygen-enriched gas in the oxygen storage device 400 can enter the gas mixing valve through the oxygen inlet 212 or can be directly discharged to the air through the air pressure regulating valve 170, so that the pressure balance of the oxygen generation system is maintained. The nitrogen-rich gas with the oxygen content of 10-15 percent can be directly discharged into the air or enter a gas mixing valve through a two-position three-way electromagnetic valve. In the treatment process, when high oxygen content gas is required to be provided, for example, when gas with the oxygen content of 30% -40% is required to be provided, the system controls nitrogen-rich gas with the oxygen content of 10% -15% to be discharged to the air, and the oxygen-rich gas and the air in required proportion are mixed to obtain gas with the set oxygen content by controlling the corresponding valve openings of the oxygen inlet 212 and the second air inlet 211; meanwhile, the pressure inside the system is maintained balanced by adjusting the air pressure adjusting valve 170. When a low oxygen content gas is required, for example, a gas with an oxygen content of 10% to 15% is required to be provided, the valves corresponding to the nitrogen-rich gas inlet 213 may be controlled to be opened, and the valves corresponding to the oxygen inlet 212 and the second air inlet 211 may be controlled to be closed, and at the same time, the pressure inside the system may be maintained to be balanced by adjusting the pressure regulating valve 170.
Further, referring to fig. 3, fig. 3 is a schematic structural diagram of an intermittent hyperhypoxic training system according to another embodiment of the invention. When the PSA oxygen generator 110 performs oxygen generation by adsorption and separation of air, the PSA oxygen generator 110 has a zeolite molecular sieve, which has high adsorption to nitrogen, and absorbs nitrogen, carbon dioxide, and the like under pressurized conditions to produce oxygen, and the nitrogen and carbon dioxide adsorbed after depressurization are released from the zeolite molecular sieve to obtain nitrogen-rich gas. Therefore, in this embodiment, in order to pressurize the air, the air compressor 120 is further connected to the first air inlet 111, and is used for compressing the air and increasing the air pressure, so that the zeolite molecular sieve in the PSA oxygen generator 110 adsorbs nitrogen to prepare oxygen. After the air is pressurized, the temperature of the air can rise after the air is compressed, the adsorption quantity of the zeolite molecular sieve is reduced due to overhigh air temperature, and the oxygen generation effect is influenced. Therefore, optionally, with continuing reference to fig. 3, an air cooling device 150 is further connected between the air compressor 120 and the first air inlet 111, and the air cooling device 150 is used for reducing the temperature of the compressed air. Because harmful substances such as dust may exist in the air, the existence of the dust not only causes the finally prepared mixed gas to contain the dust, affects the quality of the mixed gas, but also pollutes the molecular sieve in the oxygen production device 110, so that the gas adsorption capacity of the molecular sieve is reduced. Therefore, optionally, a first air purification device 130 can be connected to the first air inlet 111 for purifying air. In addition, the presence of moisture can affect the adsorption of the zeolite molecular sieve due to the presence of some moisture in the air. Therefore, optionally, an air drying device 140 is further connected to the first air inlet 111 for removing water from the air to reduce the moisture content of the air. It should be understood that all of the first air purifying device 130, the air drying device 140 and the air cooling device 150 may be provided at the same time, or only one or more of them may be provided, the first air purifying device 130, the air drying device 140 and the air cooling device 150 may be collectively referred to as an air processing device, and the air drying device 140 and the air cooling device 150 may be selected from air coolers having both cooling and drying functions. Wherein, when the air treatment device comprises a plurality of devices, the air compressor 120 and the air treatment device are connected in series to the first air inlet.
Further, in order to mix the mixed gas more uniformly, please continue to refer to fig. 3, the gas mixing device further includes a gas mixing chamber communicated with the gas mixing valve and the breathing mask, and the gas mixing chamber includes a mixed gas inlet communicated with the mixed gas outlet and a second mixed gas outlet communicated with the breathing mask. The mixed gas in the gas mixing valve enters the gas mixing cavity and is further mixed in the gas mixing cavity, so that more uniform mixed gas is obtained, and the quality of the mixed gas is improved, so that the oxygen concentration of the mixed gas is more accurately controlled.
Further, in the case of preparing the mixed gas of a desired oxygen concentration by mixing the air and two of the oxygen gas and the nitrogen-rich gas prepared by the oxygen generator 110, the higher the purity of the oxygen gas is, the easier the concentration control of the respective gases is, and if the purity of the prepared oxygen gas is low, the oxygen concentration of the mixed gas may not reach the desired oxygen concentration (high oxygen concentration). Therefore, with continued reference to fig. 3, optionally, in the present embodiment, the oxygen-containing gas generating apparatus 100 further comprises an oxygen purifying device 180, wherein the oxygen purifying device 180 is connected between the oxygen outlet 112 of the oxygen generating device 110 and the oxygen inlet 212 of the gas mixing valve 210. The oxygen produced by the oxygen producing device 110 enters the oxygen purifying device 180 through the oxygen outlet 112 and is further purified in the oxygen purifying device 180 to improve the purity of the oxygen. The purified oxygen enters the gas mixing valve 210 through the oxygen inlet 212 to participate in the generation of the mixed gas. The oxygen purifying device 180 may be any one of the existing oxygen purifying devices 180, and is not particularly limited herein, and optionally, the oxygen purifying device 180 may be an SM air membrane oxygen separation device. The oxygen purification device 180 can improve the purity of oxygen, so that the regulation and control of the mixed gas are simpler and more convenient, and the mixed gas with higher oxygen concentration can be prepared.
Further, in order to improve the comfort of the user during the intermittent hyperhypoxic training, please continue to refer to fig. 3, the respiratory training system is further provided with a gas quality adjusting element (not shown) connected in series between the first mixed gas outlet 214 and the respiratory mask 220, wherein the gas quality adjusting element comprises at least one of a gas humidifier 240, a gas perfuming device 250 and an anion generator 260. The gas humidifier 240 is used for humidifying the mixed gas to increase the humidity of the mixed gas; the gas perfuming device 250 comprises a perfuming agent for perfuming the mixed gas so that the mixed gas has a fragrance, and the type of the perfuming agent can be selected according to actual needs; the negative ion generator 260 is used to generate negative ions from the mixed gas. The quality of the mixed gas is improved after the mixed gas is treated by the gas quality regulating part, so that the user feels more comfortable when performing high-low oxygen intermittent training, and the diversified requirements of the user can be met.
When the intermittent hyperhypoxic training system is used for performing the intermittent hyperhypoxic training, the face of the user is covered by the breathing mask, and only the mixed gas provided by the breathing mask 220 can be inhaled, and the amount of gas inhaled by the user every time is not completely the same when the user breathes, so that the amount of gas inhaled by the user in a certain breath is larger than the amount of gas provided by the current flow of the mixed gas, and insufficient gas supply may be caused. Therefore, further, with continuing reference to fig. 3, in the present embodiment, the breathing exercise device 200 further comprises an air storage chamber 270 in communication with the air mixing chamber 230, wherein the air storage chamber 270 is a retractable chamber, such as an air bag. The gas storage chamber 270 is used for storing the mixed gas and supplying the gas when the mixed gas is not supplied enough. Specifically, when the mixed gas is sufficient, part of the mixed gas enters the gas storage cavity 270 from the gas mixing cavity and is stored; when the gas supply is insufficient, the mixed gas stored in the gas storage chamber 270 enters the mixed gas chamber, and the mixed gas is supplied to the gas mixing chamber. It is understood that the size of the air storage cavity 270 may be set according to practical circumstances, and is not particularly limited thereto, for example, the size of the air storage cavity 270 may be 5L.
Further, with continued reference to fig. 3, in this embodiment, the intermittent hyperhypoxic training system is further provided with a gas pump 280 (relay pump) connected between the gas mixing valve and the breathing mask. The gas pump 280 is connected to the controller 300, and when the gas pump 280 is activated, the gas pressure of the mixed gas output from the first mixed gas outlet 214 can be increased. The controller 300 is also used to control the operation parameters of the gas pump 280 to adjust the gas pressure of the mixed gas output from the first mixed gas outlet 214 of the gas mixing valve 210. Optionally, when the gas mixing apparatus includes a gas mixing chamber 230, the gas pump 280 is connected between the gas mixing valve 210 and the gas mixing chamber 230. Specifically, when detecting that the pressure of the mixed gas exceeds a preset pressure threshold, the controller 300 adjusts the opening of the opening and closing member so that the pressure of the mixed gas is reduced; when the pressure of the mixed gas is too low, the opening of the opening and closing member may be adjusted first, and if the opening of each gas valve is increased, and the pressure is still less than the preset pressure threshold after the opening of the opening and closing member is increased, the gas pump 280 may be controlled to operate to increase the pressure of the mixed gas. That is, in the solution provided in this embodiment, the pressure of the mixed gas is adjusted by the gas mixing valve 230 and the gas pump 280, so as to improve the accuracy of the pressure control of the mixed gas.
In the intermittent hyperhypoxic training using the intermittent hyperhypoxic training system, since the face of the user is covered by the breathing mask, only the mixture gas provided by the breathing mask 220 can be inhaled, and thus, when the pressure of the mixture gas is too high or too low, the user is not comfortable and may be dangerous in a serious case. Therefore, with further reference to fig. 3, the gas mixing chamber 230 further includes a gas pressure balance opening 233, the gas pressure balance opening 233 is communicated with a gas pressure balance valve 290, and the gas pressure balance valve 290 is opened to connect the gas mixing chamber 230 with the outside air. The air pressure balancing valve 290 is connected to the controller 300 to receive a control command sent by the controller 300, and is opened or closed according to the control command. Specifically, when the intermittent high-low oxygen training system operates, the air pressure of the mixed gas is detected in real time or at regular time, and when the air pressure of the mixed gas exceeds the preset air pressure range, the controller 300 sends a starting instruction to the air pressure balance valve 290 to control the air pressure balance valve 290 to be opened so as to balance the pressure of the mixed gas and prevent the mixed gas from being threatened by too high or too low pressure. Further, when the air pressure of the mixed gas is lower than the external atmospheric pressure, the external air will enter the mixed gas chamber after the air pressure balance valve 290 is opened, and then enter the breathing mask 220 to be inhaled by the user, so optionally, an air filter may be further disposed on the air pressure balance valve 290 for filtering the air. Further, when the intermittent hypoxia training system provided by the present embodiment includes the gas pump 280 and the gas storage chamber 270, the gas pressure of the mixed gas is not too low in general, and therefore, optionally, the gas pressure balance valve 290 may be a one-way valve, that is, when the gas pressure balance valve 290 is opened, only the mixed gas is allowed to flow out through the gas pressure balance valve 290, and the external air cannot enter the gas mixing chamber 230, and when the gas pressure balance valve 290 is a one-way valve, an air filter is not required. When the intermittent high-low oxygen training system provided by the embodiment is used for performing intermittent high-low oxygen training, the system stops immediately after the air pressure balance valve is opened and error reporting information is output when the system is still abnormal. Further, under the abnormal power failure mode, the system can normally release the pressure, and no residual pressure exists in the system under the power failure mode. Further, the intermittent high-low oxygen training equipment can be further provided with an emergency braking button, and when the controller receives an emergency instruction triggered by the emergency braking button, the intermittent high-low oxygen training system is controlled to stop providing gas with the current oxygen concentration, and the intermittent high-low oxygen training system is controlled to output gas with the oxygen content of 30%.
