The higher oxygen partial pressure provided by the micro-compression oxygen chamber can alleviate the body's hypoxia and meet the body's health needs. At present, the existing micro-compression oxygen chamber system usually has a single high-power air compressor, which is separated from the experience chamber. Because the single high-power air compressor has large vibrations and noise, it affects the experience of customers in the experience chamber, and cannot be combined with the experience chamber to form an integrated micro-compression oxygen chamber, which is not convenient for transportation and increases the workload of on-site assembly. Moreover, when a single air compressor fails, the entire micro-compression oxygen chamber equipment will be unable to operate, and the risk resistance is poor. Utility Model Content

DETAILED DESCRIPTION

[0026] Embodiment 1:

[0027] In a typical embodiment of the present invention, Figure 1-Figure 3 As shown, an intelligent micro-compression oxygen chamber system is provided, including an oxygen chamber, an air compressor 31, an air pressure sensing module, a gas concentration control module, a temperature control module, etc. In this embodiment, the single high-power air compressor of the traditional micro-compression oxygen chamber system is replaced by multiple small air compressors 31 with low power and less vibration and noise, so as to facilitate combination with the experience cabin into an integrated micro-compression oxygen chamber equipment.

[0028] In addition, a gas flow detection switch 32 is provided at the gas outlet of each air compressor 31; the multiple air compressors 31 are operated alternately, which can prevent the phenomenon that a fixed air compressor 31 is always in operation, thereby increasing the overall service life of the equipment.

[0029] Multiple air compressors 31 are independent of each other, so that the oxygen chamber can operate at the set pressure increase rate until the oxygen chamber target pressure reaches a dynamic pressure stabilization equilibrium state. In order to quickly determine the operating status of the air compressor 31, a gas flow detection switch 32 is installed at the air outlet of the air compressor 31. The gas flow detection switch 32 can sense the change of the air flow in the pipeline. When the air outlet of the running air compressor 31 does not detect the change of the gas flow, the information is transmitted to the central processing unit 1, so that the air compressor fault location is displayed on the terminal panel, reminding the operation and maintenance personnel to deal with the system fault in time. At the same time, a gas flow detection switch 32 is also arranged behind the electric regulating valve in the oxygen chamber exhaust system to achieve the function of timely discharge and decompression of the exhaust gas in the oxygen chamber system.

[0030] The air pressure sensing module, the gas concentration control module, and the temperature control module are all connected to the central processing unit 1; wherein the air pressure sensing module includes an air pressure sensor 4 and a pressure sensor 7, the air pressure sensor 4 is installed on the top of the oxygen chamber to monitor the ambient air pressure; the pressure sensor 7 is installed inside the oxygen chamber to monitor the air pressure inside the chamber; Figure 4 As shown, when the preset air pressure is greater than the ambient air pressure, the air compressor 31 is turned on to increase the pressure, otherwise the air compressor 31 is turned on to reduce the pressure; by comparing and analyzing the ambient air pressure and the target air pressure data in the cabin, the increase / decrease rate is given, so that the micro-pressure oxygen chamber system can still operate automatically after changing the use altitude environment or the use location.

[0031] When the altitude of the oxygen chamber changes, the oxygen concentration and air pressure corresponding to the altitude are converted into electrical signals and sent to the central processing unit 1 for storage. Once the oxygen chamber system is started, the central processing unit 1 quickly communicates with the pressure system 3 and the oxygen supply system 2 to control the corresponding valve opening to achieve a quick response.

[0032] like Figure 3 As shown, the oxygen supply system 2 includes an oxygen buffer tank 21 and an oxygen concentrator 22. The oxygen buffer tank 21 is connected to multiple oxygen concentrators 22. The oxygen concentrators 22 and the oxygen buffer tank 21 are connected by a hose, and a flow switch is installed between the oxygen concentrators 22 and the oxygen buffer tank 21. The pressure system 3 includes a compressed air buffer tank 33, and the compressed air buffer tank 33 is connected in parallel with multiple air compressors 31.

[0033] The gas concentration control module includes a gas concentration sensor 6. The gas concentration sensor 6, the pressure sensor 7, the oxygen supply system 2 and the central processing unit 1 together constitute a negative feedback, ensuring that the air pressure and gas concentration in the oxygen chamber are always within a safe range.

[0034] The temperature control module includes a temperature and humidity sensor 8 and an alarm device 9, which are respectively connected to the central processing unit 1. The temperature and humidity sensor 8 dynamically monitors the ambient temperature and humidity in the system, and ensures that the ambient temperature and humidity in the system are maintained within the range of 25±3℃ and 45-60% respectively through negative feedback regulation, further improving the comfort level in the cabin. When the gas concentration sensor 6 detects that the gas concentration or system temperature exceeds the threshold, it will trigger the alarm device 9 in the oxygen cabin.

[0035] It should be noted that the alarm device 9 is a prior art, and the present embodiment does not improve its structure, so it will not be described in detail.

[0036] A counting sensor 5 is installed on the door of the oxygen chamber. When multiple users enter the oxygen chamber, the counting sensor 5 will obtain the level change and store it in the central processing unit 1. The central processing unit 1 controls the oxygen supply of the oxygen supply system 2 so that the oxygen in the oxygen chamber quickly reaches the required concentration.

[0037] This embodiment uses multiple small air compressors 31 to replace a single high-power air compressor, which can reduce the vibration and noise of the equipment. It can be integrated with the experience cabin to facilitate transportation and reduce the workload of on-site assembly; multiple air compressors 31 operate alternately to avoid the phenomenon of a single air compressor running all the time, thereby increasing the service life of the overall device. At the same time, the air compressor 31 is equipped with a gas flow detection switch 32, which can monitor the status of the air compressor 31 in real time, and quickly determine the fault location when a fault occurs, and promptly alarm to improve safety.

[0038] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
