Description

Technical Field

[0001] The present application relates to the technical field of micro-pressure soft oxygen chambers, and in particular to a micro-pressure soft oxygen chamber with an autonomous regulating function. Background Art

[0002] The micro-pressure soft oxygen cabin is for the purpose of health care. It is composed of a cabin made of high-strength medical-grade TPU nanocomposite fiber material and a pressurization module, an oxygen production module, and a dehumidification module that are freely combined according to customer functional requirements; fresh air and high-concentration oxygen are continuously input into the cabin through the pressurization module and the oxygen production module, so that the cabin is stabilized at no more than 1.3 atmospheres and a safe and specific oxygen-rich atmosphere. In this environment, due to the increase in pressure, a large amount of oxygen is dissolved in the blood, the human body's blood oxygen capacity is significantly increased, the blood oxygen partial pressure and blood oxygen diffusion capacity are improved, and the effective radius of oxygen is increased. Combined with the rapid increase in oxygen saturation, the dissolved oxygen continues to increase, opening up an effective channel for the human body to absorb oxygen highly. A large number of oxygen molecules enter the body fluids from the respiratory tract and skin, thereby increasing the dissolved oxygen content in the body by more than 5 times, thereby playing a health care role. It is widely used in different fields, such as adaptation training for people in plateau areas, training and rehabilitation of athletes, and medical care.

[0003] There are two situations regarding the working pressure of micro-pressure soft oxygen chambers on the market: the first is that the working pressure cannot be adjusted (the set pressure of the automatic pressure relief valve is set according to user needs at the factory. When the pressure in the cabin reaches the set pressure of the automatic pressure relief valve, the automatic pressure relief valve begins to relieve pressure, thereby ensuring that the working pressure of the cabin fluctuates within the set range). The second is that the working pressure cannot be adjusted autonomously according to user needs during use. That is to say, after the working pressure is set before use, it cannot be adjusted during use and can only be shut down and the pressure can only be re-set after leaving the cabin, which seriously affects the user experience.

[0023] The following is combined with Figure 1-3 This application is described in further detail.

[0024] The present application embodiment discloses a micro-pressure soft oxygen chamber with self-regulating function. Figure 1 , Figure 2 and Figure 3The micro-pressure soft oxygen chamber with autonomous adjustment function includes an oxygen chamber 1, a pressurization module, an oxygen production module, a dehumidification module and a control system 5. The pressurization module is used to pressurize the air input into the oxygen chamber 1, the dehumidification module is used to dehumidify the pressurized air, the oxygen production module is used to supply oxygen to the oxygen chamber 1, and the control system 5 includes a pressure detection device 51 and a pressure regulating device 52. The pressure detection device 51 is used to detect the air pressure in the oxygen chamber 1, and the pressure regulating device 52 is used to adjust the air pressure in the oxygen chamber 1 according to the pressure value of the oxygen chamber 1 detected by the detection device. The pressurization module and the dehumidification module are connected to the oxygen chamber 1 through a first air pipe 6.

[0025] When the oxygen chamber 1 is in use, the air introduced into the oxygen chamber 1 is first pressurized by the pressurization module, and then the pressurized air is dehumidified by the dehumidification module. The dehumidified air is introduced into the oxygen chamber 1. At this time, oxygen is introduced into the oxygen chamber 1 through the oxygen production component. When the oxygen chamber 1 is used up, the control system 5 depressurizes the oxygen chamber 1. The user can walk out of the oxygen chamber 1 only when the pressure in the oxygen chamber 1 is lower than 1KPa. When the pressure in the oxygen chamber 1 exceeds the design value, the pressure detection device 51 detects the corresponding air pressure signal and sends it to the pressure regulating device 52. The pressure regulating device 52 adjusts the pressure in the oxygen chamber 1 to effectively control the working pressure in the oxygen chamber 1, thereby improving the user experience.

[0026] Reference Figure 1 and Figure 2 In the embodiment of the present application, the pressurizing module includes an oil-free air compressor unit 2, and the first air pipe 6 is used to connect the output end of the oil-free air compressor unit 2 and the input end of the dehumidification module; when the oxygen chamber 1 is pressurized, the oil-free air compressor is started, and the oil-free air compressor compresses the air. The compressed air passes through the dehumidification module to remove moisture from the compressed air, and then the dehumidified air is passed into the oxygen chamber 1, so that the air pressure in the oxygen chamber 1 gradually increases.

[0027] Reference Figure 1 and Figure 2 In the embodiment of the present application, the dehumidification module includes a semiconductor cooling and dehumidification device 4, which is a semiconductor refrigeration sheet. The first air pipe 6 includes a first tube body 61 and a second tube body 62. The first tube body 61 is used to connect the oil-free air compressor and the semiconductor cooling and dehumidification device 4, and the second tube body 62 is used to connect the semiconductor cooling and dehumidification device 4 and the oxygen chamber 1. When the dehumidification module is started, the compressed air enters the semiconductor cooling and dehumidification device 4 through the first pipe 5231, and the dry gas after passing through the semiconductor cooling and dehumidification device 4 enters the second tube body 62, and then enters the oxygen chamber 1 through the second tube body 62.

[0028] Reference Figure 1 and Figure 2In the embodiment of the present application, the oxygen production module includes an oxygen production unit 3, and an oxygen supply pipe is provided at the output end of the oxygen production unit 3, and the oxygen supply pipe is used to connect the oxygen chamber 1; when oxygen is introduced into the oxygen chamber 1, the oxygen production unit 3 is started, and the oxygen produced by the oxygen production unit 3 is transported to the oxygen chamber 1 through the oxygen supply pipe, and the operation is simple and convenient.

[0029] Reference Figure 2 and Figure 3 In the embodiment of the present application, the pressure detection device 51 includes a pressure-taking tube 511 and a pressure sensor 512. One end of the pressure-taking tube 511 is used to connect to the oxygen chamber 1, and the other end is used to connect to the pressure sensor 512. The pressure detection device 51 also includes a controller. The controller is electrically connected to the pressure sensor 512. The pressure sensor 512 is used to detect the pressure of the pressure measuring tube and send a detection signal to the controller. The controller is used to receive the signal sent by the pressure sensor 512 and send a corresponding pressure regulation signal to the pressure regulating device 52 to regulate the pressure of the oxygen chamber 1; as the air pressure in the oxygen chamber 1 increases, the pressure sensor 512 receives the corresponding pressure signal, and the pressure sensor 512 signal is transmitted to the controller. The controller receives the pressure signal and sends a control signal to the pressure regulating device 52. The pressure regulating device 52 regulates the air pressure in the oxygen chamber 1 to maintain the air pressure in the oxygen chamber 1 within a certain range.

[0030] In the embodiments of this application, refer to Figure 2 and Figure 3 , the pressure regulating device 52 includes a pressure relief pipe 521, an exhaust valve 522 and a pressure taking device 523. One end of the pressure relief pipe 521 is used to connect the oxygen chamber 1, and the other end is used to connect the exhaust valve 522. The exhaust valve 522 is located in the oil-free air compressor unit 2. A noise reduction device is provided in the oil-free air compressor unit 2. The noise reduction device is used to reduce the wind noise generated by the pressure relief of the exhaust valve 522. The noise reduction device includes a muffler arranged in the pressurization module. The muffler is a conventional technical means and is not described in detail here. Because the use scenario of the oxygen chamber 1 is relatively quiet, such as directly depressurizing the oxygen chamber 1, resulting in high noise in the environment, which seriously affects the experience and comfort of the oxygen chamber 1. Therefore, when the oxygen chamber 1 is depressurized, the air in the oxygen chamber 1 passes through the pressure relief pipe 521 and the exhaust valve 522, and then passes through the muffler, thereby effectively reducing the pressure relief noise, thereby improving the user experience. The pressure taking device 523 is used to adjust the pressure relief rate of the pressure relief pipe 521 according to the pressure regulating signal sent by the controller.

[0031] Reference Figure 2 and Figure 3The pressure taking device 523 includes a first pipeline 5231, a second pipeline 5232 and a third pipeline 5233 arranged between the pressure taking pipe 511 and the pressure relief pipe 521. The first pipeline 5231, the second pipeline 5232 and the third pipeline 5233 are connected in parallel between the pressure taking pipe 511 and the pressure relief pipe 521. The first pipeline 5231, the second pipeline 5232 and the third pipeline 5233 are all provided with a solenoid valve 5234. The solenoid valve 5234 is a normally closed solenoid valve 5234. The three solenoid valves 5234 are electrically connected to the controller respectively. When the user is in the oxygen chamber 1, when the pressure in the oxygen chamber 1 exceeds the set pressure, the pressure taking device 5231, the second pipeline 5232 and the third pipeline 5233 are connected in parallel between the pressure taking pipe 511 and the pressure relief pipe 521. The first pipeline 5231, the second pipeline 5232 and the third pipeline 5233 are all provided with a solenoid valve 5234. The solenoid valve 5234 is a normally closed solenoid valve 5234. The three solenoid valves 5234 are electrically connected to the controller respectively. When the pressure is set, the pressure sensor 512 obtains the pressure signal and transmits the pressure signal to the controller. The controller starts the corresponding solenoid valve 5234. The solenoid valve 5234 opens any first pipeline 5231, the second pipeline 5232, and the third pipeline 5233. The air is transmitted to the first pipeline 5231, the second pipeline 5232, and the third pipeline 5233 through the pressure taking pipe 511 and then discharged through the pressure relief pipe 521. When the pressure relief rate in the oxygen chamber 1 is low, the controller starts 2 or 3 pipelines to increase the pressure relief efficiency of the oxygen chamber 1, so that the air pressure in the oxygen chamber 1 is quickly reduced to within the set pressure range.

[0032] Reference Figure 2 and Figure 3 , further. A safety valve is provided on the oxygen chamber 1. When the pressure in the oxygen chamber 1 exceeds its set pressure, the safety valve will trip to ensure that the pressure in the oxygen chamber 1 does not exceed the maximum working pressure;

[0033] The implementation principle of a micro-pressure soft oxygen chamber with an autonomous adjustment function in the embodiment of the present application is as follows:

[0034] When the oxygen chamber 1 is in use, the air introduced into the oxygen chamber 1 is first pressurized by the pressurization module, and then the pressurized air is dehumidified by the dehumidification module. The dehumidified air is introduced into the oxygen chamber 1. At this time, oxygen is introduced into the oxygen chamber 1 through the oxygen production component. When the oxygen chamber 1 is used up, the pressure in the oxygen chamber 1 is released by opening the exhaust valve 522. The user can walk out of the oxygen chamber 1 only when the pressure in the oxygen chamber 1 is lower than 1KPa. When the pressure in the oxygen chamber 1 exceeds the design value, the pressure in the oxygen chamber 1 is adjusted by controlling the start and stop of the solenoid valve 5234, so that the working pressure in the oxygen chamber 1 is effectively controlled not to exceed ±1KPa of the set pressure, thereby improving the user experience.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
