Description

Technical Field

[0001] This utility model relates to the technical field of special environment control equipment, and in particular to a micro-pressure oxygen-enriched chamber environmental temperature regulation system. Background Technology

[0002] A micropressure oxygen chamber is a specialized medical device that provides a micropressure environment, ensuring patients can effectively, comfortably, and safely inhale oxygen in a high-pressure environment to treat diseases. Micropressure oxygen therapy has been applied in multiple disciplines, including emergency medicine, internal medicine, surgery, obstetrics and gynecology, ENT, and dermatology. Micropressure oxygen therapy refers to the method of placing patients in a micropressure oxygen chamber to receive pressurized oxygen inhalation for treatment.

[0003] A micro-pressure oxygen-enriched chamber is a device that provides a high concentration of oxygen under controlled pressure. Unlike traditional hyperbaric oxygen chambers, micro-pressure oxygen-enriched chambers typically maintain an internal pressure slightly above atmospheric pressure (approximately 1.1–1.3 atmospheres), while the oxygen concentration is generally maintained between 21% and 30%, higher than the 21% found in ordinary air. This slightly increased pressure and oxygen-enriched environment helps increase the dissolved oxygen content in the blood, promoting more efficient oxygen absorption by body tissues, thereby improving health, assisting in treatment, and enhancing bodily functions.

[0004] The operation of a low-pressure oxygen-enriched chamber is mainly based on two core principles:

[0005] Slight pressurization: A slight increase in cabin pressure can increase the ability of oxygen molecules to enter the plasma (the liquid part of blood), effectively improving tissue oxygen supply even without relying on red blood cell transport.

[0006] High-concentration oxygen supply: Oxygen-rich air is delivered into the cabin through an oxygen generator or centralized oxygen supply system to further improve blood oxygen levels, which helps repair damaged cells, improve metabolism and enhance immunity.

[0007] In short, a low-pressure oxygen-enriched chamber provides the human body with a better oxygen supply in a comfortable state through "moderate pressure + higher oxygen concentration".

[0008] Due to their high safety and comfortable experience, low-pressure oxygen-enriched chambers have been widely used in many fields:

[0009] Rehabilitation medicine: used as an adjunct treatment for diseases such as sequelae of stroke, chronic fatigue syndrome, diabetic foot, and postoperative recovery.

[0010] Sports recovery: Professional athletes use micro-pressure oxygen chambers to accelerate muscle repair, reduce inflammation, and improve recovery speed.

[0011] Beauty and anti-aging: Improves skin oxygen supply, promotes cell metabolism, and helps to tighten the skin and reduce wrinkles.

[0012] Sub - health conditioning: Relieve stress, improve sleep, enhance physical fitness, suitable for people with high work pressure for a long time and those who stay up late.

[0013] High - altitude adaptation: Help people entering high - altitude areas quickly adapt to the hypoxic environment and prevent altitude sickness.

[0014] In addition, the micro - pressure oxygen - enriched chamber also shows broad application prospects in pet rehabilitation, rehabilitation of children with special needs (such as autism intervention), health care for the elderly, etc.

[0015] Generally speaking, the safety of the micro - pressure oxygen - enriched chamber is very high. Due to the gentle pressure change and controllable oxygen concentration, the vast majority of people can use it with confidence. As a health technology product that combines comfort and functionality, the micro - pressure oxygen - enriched chamber is increasingly entering the fields of medical treatment, sports rehabilitation, and health management. Whether it is to improve the sub - health state or assist in disease rehabilitation, the micro - pressure oxygen - enriched chamber provides a gentle and effective new option.

[0016] For the above - mentioned related technologies, the applicant found that there are mainly three refrigeration methods for domestic similar micro - pressure oxygen - enriched chambers at present: 1. Fluorine air - conditioner (medium R410 refrigerant); 2. Fluorine air - conditioner (medium R32 refrigerant); 3. Water air - conditioner (medium water). The air - conditioners developed through the above three media are used for temperature adjustment, and it is an independent control system of the air - conditioner. There are the following two problems with the independent control of the air - conditioner for temperature adjustment using the above 3 media: 1. The independent control system of the air - conditioner needs to be manually started and stopped, which is inconvenient to operate; 2. It cannot be linked with the cabin control system of the micro - pressure oxygen - enriched chamber, resulting in inconvenience during use. Content of the Utility Model

[0017] Aiming at the deficiencies of the existing technology, the utility model provides an environmental temperature adjustment system for a micro - pressure oxygen - enriched chamber, which is an environmental temperature adjustment system specially designed to maintain a suitable temperature inside the micro - pressure oxygen - enriched chamber. Under the conditions of maintaining micro - pressure (usually 1.1 - 1.3 atmospheres) and oxygen - enrichment (oxygen concentration 21% - 30%), it ensures that the temperature inside the cabin is stable within a comfortable range, and the temperature can be set arbitrarily, usually 20 - 26°C. It automatically controls the start and stop of the environmental temperature adjustment system according to the change of temperature, realizing the linkage control between the micro - pressure oxygen - enriched chamber and the environmental temperature adjustment system, which is convenient for operation and use.

[0018] The technical solution of the utility model to solve the above - mentioned technical problems is as follows:

[0019] An environmental temperature adjustment system for a micro - pressure oxygen - enriched chamber includes a control center module, a temperature sensing module, an actuator module, and a safety protection module. The control center module is electrically connected to the temperature sensing module. The safety protection module is installed on the actuator module, and the safety protection module and the actuator module are respectively electrically connected to the control center module.

[0020] Furthermore, the control center module includes a main PLC controller and a control panel, with the control panel connected to the main PLC controller via a circuit.

[0021] Furthermore, the temperature sensing module includes a non-contact temperature measurement unit and a temperature and humidity composite sensor, which are respectively connected to the control center module via circuits.

[0022] Furthermore, the actuator includes a variable frequency compressor unit and an in-chamber circulating fan, with the in-chamber circulating fan placed inside the micro-pressure oxygen-enriched chamber and the variable frequency compressor unit placed outside the micro-pressure oxygen-enriched chamber.

[0023] Furthermore, the safety protection module includes an overheat protection device, a low-temperature antifreeze protection device, and a linkage control unit. The linkage control unit is electrically connected to the overheat protection device and the low-temperature antifreeze protection device, respectively. The overheat protection device, the low-temperature antifreeze protection device, and the linkage control unit are all installed on the variable frequency compressor unit.

[0024] Furthermore, both the variable frequency compressor unit and the cabin circulating fan are connected to a water receiving device.

[0025] In summary, compared with the prior art, the beneficial effects of the above technical solution are:

[0026] This application discloses an environmental temperature regulation system specifically designed to maintain a suitable temperature within a low-pressure oxygen-enriched chamber. Under conditions of low pressure (typically 1.1–1.3 atmospheres) and oxygen enrichment (oxygen concentration 21%–30%), it ensures the chamber temperature remains stable within a comfortable range. The temperature can be set arbitrarily, typically between 20 and 26°C. Through a coordinated control combination between the control center module, temperature sensing module, actuator module, and safety protection module, the system automatically controls the start and stop of the environmental temperature regulation system in response to temperature changes. This achieves coordinated control between the low-pressure oxygen-enriched chamber and the environmental temperature regulation system, facilitating operation and use. Attached Figure Description

[0031] The principles and features of this utility model are described below with reference to all the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0032] This utility model discloses a micro-pressure oxygen-enriched chamber environmental temperature regulation system.

[0033] Reference Figure 1 and Figure 2 As shown, a micro-pressure oxygen-enriched chamber environmental temperature control system includes a control center module 1, a temperature sensing module 2, an actuator module 3, and a safety protection module 4. The control center module 1 and the temperature sensing module 2 are connected by a circuit. The safety protection module 4 is installed on the actuator module 3, and both the safety protection module 4 and the actuator module 3 are connected to the control center module 1 by a circuit. Under conditions of maintaining micro-pressure (typically 1.1–1.3 atmospheres) and oxygen enrichment (oxygen concentration 21%–30%), the system ensures that the temperature inside the chamber remains stable within a comfortable range. The temperature can be set arbitrarily, typically from 20 to 26°C. Through the coordinated control combination among the control center module 1, the temperature sensing module 2, the actuator module 3, and the safety protection module 4, the system automatically controls the start and stop of the environmental temperature control system according to temperature changes, achieving coordinated control between the micro-pressure oxygen-enriched chamber and the environmental temperature control system, facilitating operation and use.

[0034] The control center module 1 includes a main PLC controller 11 and a control panel 12, which are connected to the main PLC controller 11 via circuitry. The main PLC controller 11 receives signals from various sensors, calculates the temperature difference, and generates control commands. The control panel 12 can be an integrated touchscreen embedded in the main control interface of the cabin, supporting temperature setting and status monitoring.

[0035] The temperature sensing module 2 includes a non-contact temperature measurement unit 21 and a temperature and humidity composite sensor 22. The non-contact temperature measurement unit 21 and the temperature and humidity composite sensor 22 are respectively connected to the control center module 1 via circuits. The non-contact temperature measurement unit 21 monitors the temperature of the cabin surface in real time, and the temperature and humidity composite sensor 22 collects the temperature and humidity data of the air inside the cabin.

[0036] The actuators include a variable frequency compressor unit 31 and an in-chamber circulating fan 32. The in-chamber circulating fan 32 is located inside the low-pressure oxygen-enriched chamber, while the variable frequency compressor unit 31 is located outside the chamber. Both the variable frequency compressor unit 31 and the in-chamber circulating fan 32 are connected to a water receiving device 33. The variable frequency compressor unit 31 adjusts its cooling power (adjustable from 30% to 100%) according to PLC commands, and the forced air convection of the in-chamber circulating fan 32 eliminates temperature stratification.

[0037] The safety protection module 4 includes an overheat protection device 41, a low-temperature antifreeze protection device 42, and a linkage control unit 43. The linkage control unit 43 is electrically connected to the overheat protection device 41 and the low-temperature antifreeze protection device 42, respectively. All three devices are installed on the variable frequency compressor unit 31. The overheat protection device 41 automatically cuts off power when the temperature of the variable frequency compressor unit 31 is greater than 85°C, and the low-temperature antifreeze protection device 42 activates the PTC heating function when the ambient temperature is less than 5°C.

[0038] Fully automatic control, with a temperature fluctuation range of ≤±0.5℃, requiring no manual intervention; deeply integrated, sharing data with the oxygen chamber main control system to achieve coordinated regulation; energy saving and consumption reduction, variable frequency technology reduces the average power consumption of the compressor by 40%; safety redundancy, dual protection mechanisms (overheating / freezing) improve equipment reliability.

[0039] The implementation principle of the micro-pressure oxygen-enriched chamber environmental temperature regulation system of this utility model embodiment is as follows:

[0040] The workflow is as follows: the user sets the target temperature (e.g., 24℃) via the touch control panel 12. The main control PLC controller 11 compares the set value with the measured value in real time through the non-contact temperature measurement unit 21 and the temperature and humidity composite sensor 22: if the measured value > the set value, the variable frequency compressor unit 31 and the in-cabin circulating fan 32 are started; when the temperature difference is ≤0.5℃, the low-frequency maintenance mode is entered. In case of abnormality, the overheat protection device 41, the low-temperature antifreeze protection device 42 and the linkage control unit device 43 are triggered to activate protection and alarm (e.g., the variable frequency compressor unit 31 overheats, or the humidity exceeds the standard).

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
