Description

Technical Field

[0002] A micro-pressure oxygen chamber is a sealed device that provides users with an oxygen-rich, micro-pressure environment by controlling the chamber pressure slightly above atmospheric pressure (usually 1.1 to 1.3 standard atmospheres) and increasing the oxygen concentration to 23% to 40% (higher than the 21% oxygen concentration in ordinary air). Its core principle is to use the micro-pressure environment to increase the amount of oxygen dissolved in the blood and tissues, promote metabolism, and improve microcirculation. It is widely used in medical rehabilitation (such as auxiliary treatment of hypoxic diseases), sports recovery, and sub-health conditioning.

[0003] When a microcompression oxygen chamber is used continuously by multiple people or operates uninterruptedly for a long time, the carbon dioxide concentration in the chamber may gradually increase, even exceeding the safety standard of 1%. At the same time, the chamber may be filled with various odors caused by the user's sweating or other reasons. The combined effect of these adverse factors can easily cause the user to experience discomfort symptoms such as dizziness and shortness of breath. More importantly, when the adsorption capacity of the filter device equipped in the chamber decreases due to long-term use, or its physical state changes significantly, it will directly affect the air quality in the chamber. In this case, the filter consumables must be replaced in time to ensure that the filtering effect can continue to meet the standards. However, the current method of replacing filter consumables is not only too cumbersome in operation and requires a lot of time and effort, but also difficult to replace the filter consumables in time in actual operation, which to a certain extent affects the normal use and user experience of the microcompression oxygen chamber.

[0037] The present invention will be described in further detail below with reference to the accompanying drawings.

[0038] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

Therefore, the above terms should not be understood as limiting the present invention.

[0040] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0041] Example 1: Please refer to Figure 1-14A micro-pressure oxygen chamber gas exchange system includes a chamber 1 and an electric sofa chair installed in the chamber 1, and further includes: a ventilation unit 2 installed on the chamber 1, for extracting air from the chamber 1 through the ventilation unit 2, and a corresponding purification module 3 is provided on the ventilation unit 2, and the purification module 3 is used to purify the air; and; an air return mechanism 4 provided on the chamber 1, and the air return mechanism 4 is used to return the purified air to the chamber 1;

[0042] In this plan, when Sensor detection cabin 1 When the concentration is ≥0.4%, the linked ventilation unit 2 is operated to extract the air in the cabin 1 and send the extracted air to the purification module 3, which purifies the air. The purified air is then sent back into the cabin 1 by the air return mechanism 4, thus completing the air circulation purification process in the cabin 1.

[0043] It should be noted that the cabin 1 is equipped with: a pressure control system, an oxygen supply and concentration control system, a cabin door and an observation window. These are conventional settings in the field and will not be described in detail here.

[0044] Furthermore, the ventilation unit 2 includes: an exhaust pipe 5 fixed to the cabin 1, and a solenoid valve 6 is fixed to the exhaust pipe 5, a circulating fan 8 is fixed to the cabin 1 through a support frame 7, the input end of the circulating fan 8 is fixed to one end of the exhaust pipe 5, and the output end of the circulating fan 8 is fixed to an outlet pipe 9, and the outlet pipe 9 is fixed to the circulating fan 8 through a plurality of support rods, and a filter cover 10 is fixed to one end of the exhaust pipe 5 located in the cabin 1;

[0045] The air return mechanism 4 includes: an air return pipe 40 fixed to the mounting pipe 11, the other end of the air return pipe 40 extending into the interior of the cabin 1, a protective shell 41 fixed to the cabin 1, and the air return pipe 40 is located inside the protective shell 41, an air guide hood 42 fixed inside the cabin 1, and the air guide hood 42 is located diagonally above the electric sofa chair;

[0046] It should be noted that the filter cover 10 on the exhaust pipe 5 is used to filter coarse impurities to prevent them from accidentally entering the circulating fan 8 and damaging it, and the exhaust pipe 5 is located directly behind the electric sofa chair to prevent the exhaust pipe 5 from being blocked by the user when resting in the cabin 1;

[0047] It should also be noted that, through the rational arrangement of the ventilation unit 2, the air in the cabin 1 can be efficiently and quickly extracted. After a series of refined purification processes, harmful substances and impurities in the air are ensured to be completely removed. The clean air after purification is then returned to the cabin 1 at an extremely fast speed, thereby maintaining the freshness and cleanliness of the cabin air and ensuring a comfortable and healthy cabin environment.

[0048] In this solution, the ventilation unit 2 is used to extract and deliver air to the cabin 1:

[0049] when When the sensor detects that the value exceeds the preset value, the solenoid valve 6 is opened, and then the closed state of the exhaust pipe 5 is released. Then the circulating fan 8 is turned on to work, and the exhaust pipe 5 pressurizes and extracts the air in the cabin 1 and sends it to the exhaust pipe 9. The purification module 3 purifies and filters the air. The air after purification and filtration is sent into the cabin 1 through the return air pipe 40, and the air is diffused into the interior of the cabin 1 by the wind guide cover 42.

[0050] Furthermore, the purification module 3 includes: a mounting tube 11 fixed to the outlet pipe 9, on which a HEPA filter 12, an activated carbon filter 13, and a molecular sieve 14 are sequentially arranged; a moving mechanism 15 is provided on the mounting tube 11, and the moving mechanism 15 is used to move the HEPA filter 12, the activated carbon filter 13, and the molecular sieve 14 out of the mounting tube 11; a feeding member 16 is provided on the mounting tube 11, and the HEPA filter 12, the activated carbon filter 13, and the molecular sieve 14 are returned to the moving mechanism 15 through the feeding member 16;

[0051] In this solution, the HEPA filter 12, activated carbon filter 13 and molecular sieve 14 used are all air filter paper products used for air filtration. They mainly remove particulate matter (such as dust, pollen, bacteria, PM2.5, etc.) and some gaseous pollutants in the air by interception, adsorption, etc. This is a conventional setting in this field, so it will not be described in detail here.

[0052] It should be noted that the purification module 3 is first filtered by the HEPA filter 12 to intercept particulate matter in the air, including dust, pollen, mold spores, bacteria, and aerosols. It is then filtered by the activated carbon filter 13 to adsorb gaseous pollutants, such as odors such as sweat, breath odor, and volatile organic compounds that may be generated in the cabin 1. Finally, it is filtered by the molecular sieve 14 to selectively adsorb the odors generated by the breathing of people in the cabin 1. , maintain cabin 1 The concentration is within the safe range. The filtration order on the purification module 3 is: HEPA filter 12, activated carbon filter 13 and adsorbent. This order can ensure that: particulate matter is intercepted first to protect the subsequent adsorbent, and gaseous pollutants are treated in stages to avoid mutual interference. The gas entering the cabin 1 is clean, odorless and The concentration meets the standard, ensuring the safety of the environment and user experience in cabin 1;

[0053] It should also be noted that through the setting of the purification module 3, the air in the cabin 1 can be comprehensively and carefully purified and filtered. Specifically, the purification module 3 adopts a multi-stage filtration mechanism. First, the HEPA filter 12 efficiently intercepts the tiny particles in the air, and then the activated carbon filter 13 adsorbs and removes the harmful gases and odor molecules in the air. Finally, the molecular sieve 14 further refines the filtration to ensure that the harmful substances in the air are completely removed. After this series of progressive purification treatments, the purified clean gas is returned to the cabin 1, thereby effectively solving the odor problem that may appear in the cabin air and the situation where the carbon dioxide concentration exceeds the standard, and ensuring the freshness and health of the cabin air.

[0054] In this solution, the air purification process in cabin 1 is as follows:

[0055] The first step is when the cabin 1 Concentration exceeds When the sensor reaches the preset value, the ventilation unit 2 is linked to work, and the air in the cabin 1 is drawn into the purification module 3, so that the purification module 3 purifies and filters the air;

[0056] In the second step, the purified and filtered air is sent back into the cabin 1 through the return air pipe 40;

[0057] In the third step, when the consumables in the purification module 3 are saturated with adsorption, the saturated consumables are pushed out of the purification module 3 by the moving mechanism 15, the saturated consumables are discharged, the unused consumables are reinstalled on the moving mechanism 15 by the feeding part 16, and the consumables are reset to the purification module 3 by the moving mechanism 15.

[0058] Example 2: Please refer to Figure 7 - Figure 14 This embodiment further explains the first embodiment, and the difference lies in the method of replacing consumables in the purification module 3.

[0059] Specifically, the moving mechanism 15 includes: an electric push rod 18 is fixed on the mounting tube 11 through a support plate 17, and the output end of the electric push rod 18 is slidably connected to the mounting tube 11, a plurality of supporting plates 19 are fixed in the mounting tube 11, and a mounting plate 20 is slidably connected to the supporting plate 19, a channel 21 for the mounting plate 20 to pass through is opened on the mounting tube 11, and the mounting plate 20 is fixed to the output end of the electric push rod 18, a placement groove 22 is opened on the mounting plate 20, and a circular groove 23 connected to the placement groove 22 is opened on the mounting plate 20, and the mounting plate 20 is provided with a circular groove 23 connected to the placement groove 22. A groove 24 is provided on the top, and a baffle 26 is rotatably connected to the groove 24 through a rotating seat 25. The baffle 26 is adapted to the circular groove 23. A hollow groove 27 is provided on the baffle 26. The opening of the hollow groove 27 ensures that the air can pass through the purification module 3 smoothly. A mounting plate 28 is fixed to the mounting tube 11. A special-shaped groove 29 is provided on the mounting plate 20. A lever 31 is rotatably connected to the special-shaped groove 29 through a rotating rod 30. An elastic sheet 32 ​​is fixed between the lever 31 and the special-shaped groove 29, and a through hole 33 for the lever 31 to pass through is provided on the mounting tube 11.

[0060] A sealing ring 45 is fixed to the mounting plate 20, and the sealing ring 45 abuts against the outer side of the mounting tube 11. By adding the sealing ring 45, when the electric push rod 18 drives the mounting plate 20 to reset, the squeezing force between the sealing ring 45 and the outer side of the mounting plate 20 can ensure the sealing of the gap between the mounting plate 20 and the channel 21. The HEPA filter 12, the activated carbon filter 13, and the molecular sieve 14 are of the same size and all fit into the placement groove 22. The central axis of the placement groove 22 is collinear with the central axis of the mounting tube 11.

[0061] It should be noted that the length of the mounting plate 28 is greater than the length of the mounting bracket 34, and the top surface of the mounting plate 28 is arranged at the same horizontal plane as the bottom surface of the mounting plate 20. Due to the arrangement of the mounting plate 28, when the mounting plate 20 moves to a state separated from the mounting plate 28, the baffle 26 is affected by its own gravity and can flip along the axis of the rotating seat 25;

[0062] It should also be noted that the side of the mounting plate 28 away from the mounting tube 11 is set in a circular arc surface, and both sides of the supporting plate 19 are set in circular arc surfaces. The arc surface of the mounting plate 28 is consistent with the arc surface of the supporting plate 19. Through the arc surface setting of the supporting plate 19 and the mounting plate 28, it is ensured that when the baffle 26 comes into contact with the mounting plate 28 and the supporting plate 19, it can flip more smoothly, avoiding the situation where the baffle 26 flips and gets stuck.

[0063] Furthermore, the feeding member 16 includes: a mounting frame 34 fixed to the mounting tube 11, a mounting block 35 fixed to the mounting frame 34, a guide rod 36 fixed to the mounting block 35, a push plate 37 slidably connected to the mounting frame 34 and slidingly penetrating the guide rod 36, a spring 38 sleeved on the guide rod 36, one end of the spring 38 fixed to the push plate 37, the other end of the spring 38 fixed to the mounting block 35, and a transmission rod frame 39 fixed to the push plate 37;

[0064] Among them, a dust cover 43 is rotatably connected to the mounting frame 34, and the central axis of the dust cover 43 is arranged in a collinear manner with the central axis of the mounting frame 34. The addition of the dust cover 43 plays a protective effect on the interior of the mounting frame 34, preventing dust from entering the mounting frame 34 and causing contamination of the HEPA filter 12, the activated carbon filter 13 and the molecular sieve 14. At least two limit blocks 44 are fixed to the mounting frame 34, and the push plate 37 abuts against the limit blocks 44. The setting of the limit blocks 44 plays a role in limiting the push plate 37, ensuring that the activity space of the push plate 37 is limited between the limit blocks 44 and the mounting block 35;

[0065] It should be noted that the elasticity of the elastic sheet 32 ​​is less than that of the spring 38. When the lever 31 comes into contact with the push plate 37, the lever 31 is subjected to force and flips along the axis of the rotating rod 30 to be accommodated in the special-shaped groove 29. When the lever 31 comes into contact with the transmission frame rod for transmission, the side of the special-shaped groove 29 limits the lever 31, thereby driving the transmission frame rod to move.

[0066] It should also be noted that, through the coordinated arrangement of the moving mechanism 15 and the feeding member 16, when the filter consumables in the purification module 3 reach the adsorption saturation state, these adsorption saturated filter consumables can be accurately and automatically discharged. At the same time, the unused filter consumables will be reinstalled into the purification module 3, thereby realizing timely replacement of the adsorption saturated filter consumables. This process not only effectively avoids the problem of weakening purification effect caused by the decrease in adsorption capacity and change in physical state of the filter consumables, but also further strengthens the purification treatment guarantee of the air quality in the cabin 1, ensuring that the air in the cabin is always in a state of efficient purification.

[0067] In this solution, the principle of replacing any one of the HEPA filter 12, activated carbon filter 13 and molecular sieve 14 in the purification module 3 is as follows: the mounting plate 20 is moved toward the mounting plate 28 by the electric push rod 18 until the mounting plate 20 moves to a state separated from the mounting plate 28. At this time, relying on the gravity of the baffle 26, the baffle 26 is forced to flip downward along the axis of the rotating seat 25, thereby releasing the blocking state of the placement slot 22, causing the consumables in the placement slot 22 to fall, and the mounting plate 20 is reset by the electric push rod 18. , the lever 31 and the transmission rod frame 39 are squeezed and transmitted, thereby driving the push plate 37 to move along the guide rod 36 until the push plate 37 releases the blocking state of the bottom of the mounting frame 34, causing the consumables stored in the mounting frame 34 to fall smoothly into the placement groove 22. At the same time, the baffle 26 is squeezed and contacted with the arc surface of the mounting plate 28, which can drive the baffle 26 to rotate and reset. At this time, the mounting plate 28 is reset to fit in the circular groove 23 until the electric push rod 18 resets the mounting plate 20 to the inside of the mounting tube 11, thereby completing the reinstallation of the consumables.

The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
