Description

TECHNICAL FIELD

[0001] The utility model belongs to the medical, health care equipment technical field, concretely relates to a gas circulation formula negative oxygen ion oxygen cabin. BACKGROUND

[0002] The oxygen cabin is a special equipment for oxygen therapy, and has good curative effect on hypoxia, ischemic diseases, a series of diseases caused by hypoxia and ischemia, certain infectious diseases and autoimmune diseases, etc. In addition, it also has the functions of health care, beauty, recovery of energy, etc.

[0003] It is known that the human body is composed of cells, and the root cause of human diseases is cell damage. Human aging is also caused by cell aging or necrosis. The main culprit causing cell pathology or aging is excess oxygen free radicals. The causes of oxygen free radicals are as follows: oxygen enters the body through human respiration, is transported to various cells by red blood cells in the blood, and reacts with sugar and fat to produce energy. Among them, 2% of oxygen is converted into active oxygen. In addition, due to food pollution, air pollution, bacteria, viruses, radiation, anticancer agents, etc., a large amount of active oxygen will be produced in the human body. If these active oxygen cannot be removed, the human body will become sick and age.

[0004] Negative oxygen ions are called air vitamins. A large number of papers and monographs introduce that negative oxygen ions have broad-spectrum therapeutic and health care effects. According to the book "Environment-Health and Negative Oxygen Ion" edited by Lin Jinming, negative oxygen ions can regulate and improve the function of the nervous system and the brain, increase immunity, eliminate fatigue, improve sleep, increase appetite, improve the gas exchange function of the lungs, increase lung capacity, calm, stop coughing, relieve asthma, expectorant, stimulate hematopoietic function, increase red blood cells and platelets, lower blood pressure, blood sugar and blood lipids, and have certain curative effects on burns, trauma, dermatitis, etc.

[0005] Negative oxygen ions are divided into two categories: the first category is negative oxygen ions produced by natural environment such as seashore, forest, grassland and waterfall, which has long life (half-life 1 minute), high activity and small particle size, and is called ecological negative oxygen ion; the second category is negative oxygen ions produced by corona discharge, rays, ultraviolet rays and other ways, which has short life (a few seconds), low activity, large particle size, and contains ozone and nitrogen oxide compounds and other harmful substances to human health, and has obvious electrostatic effect. The first category of negative oxygen ions is beneficial to human health, and the second category of negative oxygen ions has little effect on human health and is mainly used for disinfection and sterilization. The air impact type negative oxygen ion generator is a device that uses compressed air (or oxygen) to impact water and air impact plate to produce negative oxygen ions. The negative oxygen ions produced by the device belong to the first category of negative oxygen ions, and the concentration of ecological negative oxygen ions produced is very high (up to 100 million / cm3), which is much higher than the concentration of negative oxygen ions around the waterfall in nature.

[0006] While oxygen chambers can treat illnesses and promote health, they also generate oxygen free radicals, leading to oxygen poisoning and pulmonary fibrosis. In addition, the carbon dioxide produced by people breathing in oxygen chambers gradually increases over time. Over time, the increased carbon dioxide concentration can harm the health of users. Therefore, it is necessary to develop an oxygen chamber with high concentration of negative oxygen ions and low concentration of carbon dioxide. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of existing oxygen chambers and provide a gas-circulating negative oxygen ion oxygen chamber that can create a high-concentration negative oxygen ion environment and a low-concentration carbon dioxide environment within the chamber. Specifically, this application provides a gas-circulating negative oxygen ion oxygen chamber, including a chamber body, an oxygen supply system, a negative oxygen ion gas supply system, and a circulation system;

[0008] The oxygen supply system supplies oxygen into the cabin through oxygen pipes;

[0009] The negative oxygen ion gas supply system includes an air pump and a negative oxygen ion generator. The air pump is used to supply compressed gas to the negative oxygen ion generator, and the negative oxygen ion generator supplies negative oxygen ion gas into the cabin through an air inlet connector.

[0010] The circulation system includes an in-cabin recirculation air pipe and a carbon dioxide eliminator connected by a pipeline. The first end of the in-cabin recirculation air pipe is inserted into the cabin, and the second end is connected to the carbon dioxide eliminator. The outlet of the carbon dioxide eliminator is connected to the air pump to provide at least a portion of the air source.

[0011] In some implementations, the oxygen supply system includes an oxygen generator, and the cabin cavity is provided with an oxygen outlet connector, the inlet end of which is connected to the oxygen generator, and the outlet end of which is connected to the oxygen pipe.

[0012] In some implementations, the gas-circulating negative oxygen ion chamber also includes an air conditioning system, comprising an outdoor air conditioning unit and an indoor air conditioning unit.

[0014] In some implementations, a silencer is connected to the air inlet connector, and the negative oxygen ion gas generated by the air-jet negative oxygen ion generator enters the inner cavity of the cabin after being silenced by the silencer.

[0015] In some implementations, the recirculating air pipe is located at the bottom of the cabin and its length is approximately equal to the length of the cabin. A safety valve is installed on the shell of the cabin and penetrates through the shell. When the air pressure inside the cabin exceeds a predetermined value, the safety valve releases pressure.

[0016] In some implementations, the air-impact negative ion generator includes a cup body, a cup lid, and an air-impact device. The inner cavity of the cup body is filled with water, and the air-impact device is submerged below the water surface in the inner cavity of the cup body. An air-impact hole is provided on the air-impact device to connect to the air inlet connector of the cup lid, and an air-impact plate is provided in front of the air-impact hole.

[0017] In some implementations, the carbon dioxide eliminator employs chemical absorption and / or physical absorption.

[0033] To make the technical solutions and advantages of this application clearer, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1-7 As shown, the gas-circulating negative oxygen ion oxygen chamber of this application includes a chamber body 100, an oxygen supply system 200, a negative oxygen ion gas supply system 300, and a circulation system 400.

[0035] The oxygen supply system supplies oxygen to the cabin 100 through oxygen pipe 220;

[0036] The negative oxygen ion gas supply system includes an air pump 320 and a negative oxygen ion generator 310. The air pump 320 is used to supply compressed gas to the negative oxygen ion generator 310 through a pipeline 330. The negative oxygen ion generator 310 supplies negative oxygen ion gas to the cabin 100 through an air inlet connector 340.

[0037] The circulation system 400 includes an in-cabin recirculation air pipe 410 and a carbon dioxide eliminator 420 connected by a pipeline. The first end of the in-cabin recirculation air pipe 410 is inserted into the cabin 100, and the second end is connected to the carbon dioxide eliminator 420. The outlet connector 423 of the carbon dioxide eliminator 420 is connected to the air pump to provide at least a portion of the air source.

[0038] During operation, the oxygen supply system supplies oxygen into the chamber, while the negative ion gas supply system supplies negative ion gas, creating an environment suitable for treatment and health maintenance within the chamber 100. Furthermore, the gas within the chamber 100 can circulate and return to its interior. During this circulation, the high concentration of negative ions generated by the air-jet negative ion generator 310 continuously enters the chamber, maintaining a high concentration of negative ions. Simultaneously, the carbon dioxide in the chamber is removed by the carbon dioxide eliminator 420, maintaining a low concentration of carbon dioxide within the chamber.

[0039] By adopting the solution of this application, the concentration of negative oxygen ions in the cabin cavity can reach 50,000 to 500,000 per cubic centimeter or even higher, depending on the flow rate of the air pump 320. Furthermore, since the pressure of the circulating gas at the air inlet of the air pump 320 is basically equal to the pressure in the cabin cavity, which is higher than the ambient atmospheric pressure, the power consumption of the air pump can be reduced, resulting in energy saving.

[0040] In some embodiments, the oxygen supply system 200 includes an oxygen generator 210, and an oxygen outlet connector 230 is provided inside the cabin 100. The inlet end of the oxygen outlet connector 230 is connected to the oxygen generator 210, and the outlet end is connected to the oxygen pipe 220. Oxygen is supplied to the interior of the cabin 100 or for human oxygen inhalation through the oxygen pipe 220.

[0041] In some embodiments, the gas-circulating negative oxygen ion chamber further includes an air conditioning system, comprising an outdoor air conditioning unit 510 and an indoor air conditioning unit 520. The temperature inside the chamber 100 can be regulated by the air conditioning.

[0042] In some embodiments, the circulation system 400 further includes a first reversing valve 430, a filter 440, a first one-way valve 450, and a first solenoid valve 460, wherein the first reversing valve 430, the filter 440, and the first one-way valve 450 are connected in series between the carbon dioxide eliminator 420 and the air pump 320, and the first solenoid valve 460 is connected between the cabin recirculation air pipe 410 and the carbon dioxide eliminator 420. During operation, the first reversing valve 430 is adjusted to draw in air from the outside. When the pressure inside the chamber 100 reaches the predetermined value, the first reversing valve 430 is adjusted to draw in gas from the chamber circulation pipe 410. At the same time, the first solenoid valve 460 is opened. At this time, the gas inside the chamber 100 enters the chamber circulation pipe 410, the first solenoid valve 410, the carbon dioxide eliminator 420, the first one-way valve 450, the filter 440, the first reversing valve 430, the air pump 320, the air-impact negative oxygen ion generator 310, and the air inlet connector 340 and returns to the chamber's inner cavity. In this way, the gas inside the chamber circulates and returns to the chamber's inner cavity. During the process of the gas circulating back to the chamber's inner cavity, on the one hand, the high concentration of negative oxygen ions generated by the air-impact negative oxygen ion generator is continuously input into the chamber's inner cavity, maintaining a high concentration of negative oxygen ion environment; on the other hand, the gas circulation inside the chamber removes carbon dioxide through the carbon dioxide eliminator, maintaining a low concentration of carbon dioxide environment inside the chamber.

[0043] In some embodiments, a silencer 350 is connected to the air inlet connector 340. The negative oxygen ion gas generated by the air-jet negative oxygen ion generator 310 enters the inner cavity of the cabin 100 after being silenced by the silencer 350. The silencer 350 can be a labyrinth-type silencer among resistive silencers. Such a solution can achieve filtration well without generating too much wind resistance, which justifies the implementation of the solution in this application.

[0044] In some embodiments, the in-cabin recirculation air pipe 410 is located at the bottom inside the cabin 100, and its length is comparable to that of the cabin 100, that is, it extends from the first side wall of the cabin 100 to a second wall opposite to the first side wall, for example, 1 cm or several cm away from the other side wall. The internal air circulation pipe 410 is located at the bottom, and its inlet and outlet are far apart to prevent the negative oxygen ion gas from being expelled as soon as it enters the inner cavity of the chamber 100. Also, since carbon dioxide is heavier than oxygen, more carbon dioxide is carried away. The currently popular chamber shape is square, and this application does not limit the shape of the chamber, but mainly uses a square chamber. The air inlet connector 340 and the silencer 350 are set on the side wall of the chamber. The negative oxygen ion outlet on the silencer 350 is generally horizontal, but can also be downward, directly blowing the negative oxygen ion gas towards the person on the seat. The internal air circulation pipe 410 is set at the bottom of the chamber 100. Since carbon dioxide is heavier than oxygen and nitrogen, the carbon dioxide concentration at the bottom of the chamber 100 is relatively high. The internal air circulation pipe 410 set at the bottom of the chamber 100 can expel more carbon dioxide.

[0045] In one embodiment, one of the air inlet connector 340 and the oxygen pipe 220 is located at the top of the chamber, and the other is located on the first side wall and close to the top. That is, one of them is on the same side wall into which the internal recirculation air pipe 410 extends. With this arrangement, the oxygen and negative oxygen ion gas entering the inner cavity of the chamber 100 can be fully mixed in the inner cavity of the chamber 100 and can effectively drive the gas flow in all corners of the inner cavity of the chamber 100, clearing dead corners where gases such as carbon dioxide are stored in the chamber, and fully flowing out from the internal recirculation air pipe 410. More preferably, in one embodiment, the air inlet connector 340 and the oxygen pipe 220 are respectively located on two adjacent side walls, and their installation heights are close, for example, within 5 cm of each other. They are not aligned horizontally, forming an interlaced shape. During operation, before a person enters the chamber, or when it is necessary to quickly vent gases such as carbon dioxide and nitrogen from the chamber. The entry speed of oxygen and negative oxygen ion gas from the air inlet 340 and the oxygen pipe 220 is controlled, for example, 2-5 times faster than the normal operating speed. Through the arrangement of the air inlet 340 and the oxygen pipe 220, the negative oxygen ion gas and oxygen will form a cyclone airflow within the chamber, mobilizing the gas in all spaces within the chamber. Within a few seconds, the gas in the chamber is rapidly discharged from the chamber recirculation pipe 410, achieving rapid replacement, facilitating subsequent formal use by personnel, and saving time.

[0046] In one embodiment, a safety valve 600 is provided on the shell of the cabin 100. The safety valve 600 penetrates the shell of the cabin 100. When the air pressure inside the cabin 100 exceeds a predetermined value, the safety valve 600 releases pressure.

[0047] In one embodiment, the air-impact negative oxygen ion generator 310 includes a cup body 311, a cup lid 312, and an air-impact device 313. The inner cavity of the cup body 311 is filled with water, preferably purified water or distilled water, but other types of water (tap water, mineral water, etc.) can also be used, although the concentration of negative oxygen ions produced will be lower. The air-impact device 313 is submerged below the water surface in the inner cavity of the cup body 311. An air-impact hole 3131 is provided on the air-impact device 313, which is connected to the cup lid air inlet connector 3121 provided on the cup lid 312. An air-impact plate 3132 is provided 2 to 10 mm in front of the air-impact hole 3131.

[0048] In one embodiment, the air-striking device 313 includes an air-striking tube 3134 and an air-striking head 3135. The air-striking head 3135 has a cavity inside. The air-striking tube 3134 passes through one side wall of the air-striking head 3135. A hole 3131 is provided on the air-striking tube 3134. The air-striking plate 3132 is provided inside the air-striking head 3135. The air-striking head 3135 includes a base 31351 and a cover 31352. After the base 31351 and the cover 31352 are installed, a cavity is formed inside. The base 31351 has a through hole.

[0049] In one embodiment, a water suction hole 3133 is also provided on the air-smashing pipe 3134. The water suction hole 3133 and the air-smashing hole 3131 intersect at an angle. One end of the water suction hole 3133 is connected to the air-smashing hole 3131, and the other end is connected to the inner cavity of the cup body 311. The diameter of the water suction hole 3133 is smaller than that of the air-smashing hole 3131. During operation, compressed air (oxygen) is delivered to the air-smashing hole 3131 along the air inlet pipe. The compressed air is ejected at high speed from the air-smashing hole 3131. Due to the high flow velocity of the gas in the air-smashing hole 3131, a negative pressure is formed according to Bernoulli's equation. This causes the water in the cup body 311 to be ejected at high speed from the outlet end of the air-smashing hole 3131 along with the compressed air, impacting the water and the air-smashing plate 3132, generating a high-concentration, high-humidity negative oxygen ion gas. Preferably, the diameter of the air impact hole 3131 is 0.5–3 mm, and the diameter of the water suction hole 3133 is generally 10–50% of the diameter of the air impact hole. An air impact plate is disposed 3–10 mm in front of the air impact hole. In one embodiment, the air impact hole 3131 includes, from top to bottom, a narrow diameter section 31311, a converging section 31312, and a wide diameter section 31313. The converging section has a diameter 1.5–2 times that of the narrow diameter section 31311. The water suction hole 3133 communicates with the converging section 31312. The diameter of the wide diameter section 31313 is slightly larger than that of the narrow diameter section 31311, for example, less than 1.2 times the diameter of the narrow diameter section 31311. With this design, after the gas passes through the gas impact hole 3131, it carries the water from the water intake hole 3133 to the collection section, and together with the gas, it is ejected from the coarse diameter section 31313. Moreover, this size design makes the gas carry the water better, and the concentration of negative oxygen ion gas generated by the gas impact is also higher.

[0050] In one embodiment, the top surface of the air-jetting device 313 is connected to the air guide pipe 314, and the upper end of the air guide pipe 314 is connected to the generator silencer 315. The generator silencer 315 is a labyrinth-type silencer. The air outlet 3151 of the generator silencer 315 extends out of the water surface. The water droplets that settle in the generator silencer 315 are discharged into the inner cavity of the cup body 311 along the drain outlet 3152 of the generator silencer. The negative oxygen ion gas rises to the water surface along the air guide pipe 314 and the generator silencer 315 and is output from the negative oxygen ion outlet connector 3122 provided on the cup lid 312.

[0051] In one embodiment, the air guide tube 314 is made of stainless steel, and the generator silencer 315 is made of plastic. The diameter of the air guide tube 314 is 3 to 15 mm, and the number of tubes is 2 to 8; the air outlet of the generator silencer 315 extends above the water surface inside the cup body 311.

[0052] In one embodiment, the carbon dioxide eliminator 420 employs chemical absorption and / or physical absorption.

[0053] In one embodiment, the carbon dioxide eliminator 420 includes an eliminator housing 421 and two sealed water containers 425 disposed within the cavity of the eliminator housing 421. The eliminator housing 421 is provided with a second air inlet connector 422, a second air outlet connector 423, and a carbon dioxide exhaust port 424. The second air inlet connector 422 is connected to the two sealed water containers 425 via an internal air supply pipe 426 and a second reversing valve 428, alternately inputting compressed gas into the two sealed water containers 425. The top of each sealed water container 425 is provided with three connectors: the first connector inputs compressed gas, the second connector outputs compressed gas with carbon dioxide removed, the compressed gas with carbon dioxide removed is connected to the second air outlet connector 423 and the first one-way valve 450 via a second one-way valve 429, and the third connector outputs carbon dioxide, which is discharged from the carbon dioxide exhaust port 424 via a second solenoid valve 427. This carbon dioxide eliminator removes carbon dioxide by utilizing the principle that carbon dioxide dissolves in water or other solvents under pressure, and precipitates out of the water or other solvents after pressure is released.

[0054] In one embodiment, the second carbon dioxide eliminator 420A comprises a second eliminator housing 421A, a second filter screen 422A, and a carbon dioxide absorbent 423A. The carbon dioxide absorbent comprises a solid alkaline oxide (such as calcium oxide, magnesium oxide, etc.) and a solid carrier impregnated with a liquid alkaline solution (such as KOH, NaOH, etc.).

[0055] Carbon dioxide eliminator 420 utilizes the principle that carbon dioxide solvents (water, propylene carbonate, fluorocarbons) dissolve carbon dioxide under pressure, and carbon dioxide is released from the carbon dioxide solvent when the pressure is released. The gas is removed by alternating pressure increases and decreases in several sealed water-filled containers within the carbon dioxide eliminator 420. Water is generally used as the carbon dioxide solvent; other carbon dioxide solvents are more efficient, but may leave harmful substances such as propylene carbonate and fluorocarbons (artificial blood) in the gas. The second carbon dioxide eliminator 420A uses carbon dioxide absorbents (alkalis, alkaline oxides, molecular sieves, etc.) to absorb carbon dioxide. Its advantages are high absorption efficiency and simple structure; its disadvantage is the need for periodic replacement of the carbon dioxide absorbent.

[0056] In one embodiment, a dehumidifier 102 is provided in the internal cavity of the cabin.
