Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and particularly to a dispersed oxygen generation system. Background Art

[0002] With the rapid development of modern technology, air conditioning technology plays an increasingly crucial role in people's living and working environments. In traditional air conditioning systems, the main focus is on controlling the indoor temperature, creating a suitable indoor environment through refrigeration, heating, and other means. However, in places with low oxygen content such as high altitudes and underground spaces, the partial pressure of oxygen in the atmosphere is low, and the human body is prone to hypoxia symptoms. In addition, in places with strict requirements for air quality, such as hospitals and laboratories, not only a suitable temperature is required, but also a sufficient and clean oxygen supply is equally important.

[0003] Existing oxygen generation methods usually use oxygen cylinders to supply oxygen, which only simply provides oxygen, cannot be linked with the air conditioning system, and have limited oxygen storage capacity, requiring frequent replacement, being inconvenient to use and costly. And some small oxygen generators mostly use the method of nasal catheter or mask oxygen inhalation. Not only are the users' activities restricted and the comfort is poor, but also in large areas, it is difficult to cooperate with the air conditioning system to achieve uniform oxygen distribution, and it cannot meet the needs of multiple people using simultaneously and the integration with the air conditioning function.

[0004] Therefore, it is of extremely urgent practical significance to efficiently integrate the oxygen generation function into the air conditioning system and develop a dispersed oxygen generation system that can achieve uniform dispersed oxygen supply in a large space, while cooperating with various functions of the air conditioning to achieve high efficiency, energy saving, and convenient use. Summary of the Invention

[0005] In order to efficiently integrate the oxygen generation function into the air conditioning system, the present application provides a dispersed oxygen generation system to achieve uniform dispersed oxygen supply while cooperating with various functions of the air conditioning, achieving the effects of high efficiency, energy saving, and convenient use.

[0006] The dispersed oxygen generation system provided by the present application adopts the following technical solutions: A dispersed oxygen generation system includes an outdoor unit and a terminal unit; a power device is installed inside the outdoor unit, the power device is drivingly connected to a compression device and an oxygen generation device, the compression device is connected to a gas storage device, the gas storage device is connected to a refrigeration device, the refrigeration device is connected to the oxygen generation device, the oxygen generation device is connected to a processing device, the processing device is connected to a valve device, the valve device is respectively connected to a first heat exchanger and a second heat exchanger, the first heat exchanger is thermally connected to the compression device, the second heat exchanger is thermally installed on the refrigeration device, and the valve device is connected to the terminal unit.

[0007] By adopting the above technical solution, through the collaborative work of the power device, the compression device, and the oxygen generation device, oxygen can be effectively separated from the air, improving the oxygen generation efficiency. At the same time, the setting of the first heat exchanger and the second heat exchanger realizes the recovery and utilization of energy. The first heat exchanger uses the waste heat generated by the compression device to heat the oxygen, reducing additional energy consumption; the second heat exchanger uses the low temperature of the refrigeration device to adjust the temperature of the oxygen, improving the energy utilization efficiency of the entire system. The combination of the valve device and the two heat exchangers enables the system to flexibly adjust the temperature of the output oxygen. According to different usage scenarios and requirements, oxygen at an appropriate temperature can be provided to users, improving the comfort and applicability of use. This application efficiently integrates the oxygen generation function into the air conditioning system, enabling uniform and dispersed oxygen supply in a large space and efficiently and conveniently adjusting the air temperature.

[0008] Further, the power device includes a motor, an active pulley is installed on the motor, a driven pulley is connected to the active pulley through belt drive, a drive shaft is installed on the driven pulley, the drive shaft is installed on the compression device and penetrates through the compression device, the outer side of the drive shaft is in transmission connection with the compression device, and one end of the drive shaft far from the driven pulley is in transmission connection with a speed reducer, and the speed reducer is in transmission connection with the oxygen generation device.

[0009] By adopting the above technical solution, by using the belt drive method, that is, the combination of the active pulley, the belt, and the driven pulley, the vibration and impact generated during the operation of the motor can be buffered, reducing the damage to the compression device and the oxygen generation device, and ensuring the smooth operation of the entire system. The setting of the speed reducer enables the power to be reasonably adjusted according to the different working requirements of the compression device and the oxygen generation device. The compression device requires a higher rotational speed to achieve efficient air compression, while the oxygen generation device has a lower requirement for rotational speed but requires a larger torque to drive the internal components to work. The speed reducer can reduce the rotational speed of the drive shaft to a range suitable for the oxygen generation device while increasing the torque, ensuring that the oxygen generation device can operate stably and efficiently. The structure of the entire power device is relatively simple, mainly composed of common components such as a motor, pulleys, belts, and speed reducers. This simple structure not only reduces the manufacturing cost of the equipment, but also is easy to install and adjust, and is more convenient in terms of maintenance and repair.

[0010] Furthermore, the oxygen generation device includes a rotating drum. Both ends of the rotating drum are hermetically and rotatably connected to end seats. A rotating shaft passing through the end seats is fixedly connected to the center of the rotating drum. The rotating shaft is in transmission connection with the power device. A plurality of annularly and evenly distributed oxygen generation channels are axially formed on the rotating drum. Oxygen generation molecular sieves are installed inside the oxygen generation channels. First through holes, second through holes, third through holes, and fourth through holes are respectively formed at both ends of the oxygen generation channels on the two end seats. An air inlet pipe is hermetically and fixedly installed on the first through hole. The air inlet pipe is connected to the refrigeration device. An exhaust pipe is hermetically and fixedly installed on the second through hole. A first regulating valve is installed on the exhaust pipe. A three-way pipe is hermetically and fixedly installed on the third through hole. A connecting pipe is hermetically and fixedly installed on the fourth through hole. A first one-way valve is hermetically installed between the connecting pipe and the three-way pipe. The other end of the three-way pipe is connected to an oxygen pipe. The oxygen pipe is connected to the processing device.

[0011] By adopting the above technical solution, the rotation of the rotating drum enables each oxygen generation channel to sequentially complete processes such as air intake, oxygen generation, exhaust, and oxygen collection, realizing a continuous and uninterrupted oxygen generation function. Compared with traditional intermittent oxygen generation equipment, it can provide oxygen to the subsequent system more stably and improve the oxygen generation efficiency. And through the first regulating valve, the flow rate and pressure of the exhaust gas can be adjusted according to actual needs, thereby controlling the efficiency and effect of cleaning the oxygen generation molecular sieve during the oxygen generation process.

[0012] Furthermore, the valve device includes a valve installation box. An input pipe and an output pipe are installed inside the valve installation box. The output pipe is coated with heat insulation materials on the outside; at one end of the input pipe located inside the valve installation box, a second regulating valve and a third regulating valve are installed in parallel. One end of the input pipe located outside the valve installation box is connected to the processing device; at one end of the output pipe located inside the valve installation box, a second one-way valve and a third one-way valve are installed in parallel. One end of the output pipe located outside the valve installation box is connected to the terminal machine; the first heat exchanger is connected in series between the second regulating valve and the second one-way valve, and the second heat exchanger is connected in series between the third regulating valve and the third one-way valve.

[0013] By adopting the above technical solution, the second regulating valve and the third regulating valve are used to respectively control the oxygen flow rate entering the heating path and the cooling path, and the temperature of the output oxygen can be flexibly adjusted according to actual needs. It can meet the requirements for the oxygen temperature in different scenarios. For example, warm oxygen can be provided in a cold environment, and cool oxygen can be provided in a hot environment, improving the user's comfort. At the same time, the first heat exchanger heats the oxygen using the waste heat generated by the compression device, and the second heat exchanger cools the oxygen using the low temperature of the refrigeration device, realizing the recovery and reuse of energy, improving the energy utilization efficiency of the entire system, and reducing energy consumption and operating costs.

[0014] Furthermore, the terminal includes a housing. Inside the housing, a water storage tank is installed. A tank cover is hermetically installed on the water storage tank. An inlet box is hermetically connected to the outside of the water storage tank near the tank cover. One end of the inlet box passing through the side wall of the housing is hermetically slidably connected to an inlet drawer. An inlet is provided on the inlet drawer. Inside the water storage tank on the tank cover, a gas guide box connected to the output pipe is fixedly and hermetically installed. An atomizer connected to the water storage tank is fixedly installed inside the gas guide box. The upper end of the atomizer penetrates through the tank cover. The tank cover is provided with a gas guide cylinder corresponding to the gas guide box. An exhaust hood is installed on the top of the housing corresponding to the atomizer and the gas guide cylinder.

[0015] By adopting the above technical solution, the water mist formed by the atomizer is mixed and diffused with oxygen for output, which can humidify the output oxygen and effectively avoid the irritation of dry oxygen to the human respiratory tract. Especially in a dry environment or during long-term oxygen inhalation, the moist oxygen can keep the respiratory mucosa moist, reduce discomfort symptoms such as coughing and dry throat, and improve the comfort and health effect of the user's oxygen inhalation. And the atomizer atomizes water and fully mixes it with oxygen, enabling oxygen to be better absorbed by the human body. The tiny water mist particles increase the contact area between oxygen and the respiratory mucosa, contributing to improving the utilization rate of oxygen and enhancing the oxygen inhalation effect.

[0016] Furthermore, a gas guide pipe passing through the water storage tank is fixedly connected to the gas guide box. One end of the gas guide pipe away from the gas guide box is fixedly connected to an insertion cylinder seat. A push rod is fixedly installed inside the insertion cylinder seat. One end of the output pipe away from the valve installation box is installed with an insertion cylinder corresponding to the inside of the insertion cylinder seat. The insertion cylinder is detachably inserted into the inside of the insertion cylinder seat. A sealing plate is slidably connected to the inside of the insertion cylinder corresponding to the push rod. A flange is provided on the outer end of the insertion cylinder corresponding to the end face of the sealing plate. A spring abutting against the inner end face of the sealing plate is installed inside the insertion cylinder.

[0017] By adopting the above technical solution, the design of the insertion cylinder being detachably inserted into the inside of the insertion cylinder seat makes the connection and separation operations between the output pipe and the terminal very convenient. During the installation, maintenance or movement of the equipment, the connection and disassembly of the output pipe can be quickly completed, improving work efficiency and reducing the operation difficulty. When disconnecting, the spring pushes the sealing plate to form a sealed connection with the flange, effectively preventing the leakage of oxygen inside the output pipe. This can not only avoid the waste of oxygen, reduce the operating cost, but also prevent the accumulation of high-concentration oxygen in non-use areas and reduce potential safety hazards.

[0018] Furthermore, the first heat exchanger includes a first heat exchange tube made of a heat-conducting material. The first heat exchange tube is spirally wound around the compression device. The input end of the first heat exchange tube is hermetically connected to a heat exchange input pipe, and the output end of the first heat exchange tube is hermetically connected to a heat exchange output pipe. The outside of the heat exchange output pipe is coated with heat-insulating material.

[0019] By adopting the above technical solution, the waste heat generated during the operation of the compression device is utilized to heat oxygen, which would otherwise be wasted. This is used to adjust the temperature of the oxygen output by the diffusion oxygen generation system, improving the energy utilization efficiency of the entire system and reducing the energy consumption required for additional heating.

[0020] Furthermore, the second heat exchanger includes a second heat exchange tube. The second heat exchange tube is arranged in a serpentine shape inside the refrigeration device. The input end of the second heat exchange tube is hermetically connected to a heating input pipe, and the output end of the second heat exchange tube is hermetically connected to a heating output pipe. The outside of the heating output pipe is coated with heat-insulating material.

[0021] By adopting the above technical solution, the low-temperature environment generated by the refrigeration device is used to cool oxygen, avoiding additional refrigeration equipment and energy consumption. The refrigeration capacity of the refrigeration device is maximally utilized, improving the energy utilization efficiency of the entire diffusion oxygen generation system and reducing the operating cost. The heat-insulating material outside the heating output pipe ensures the temperature stability of the low-temperature oxygen during transportation. Stable low-temperature oxygen is crucial for subsequent adjustment of the temperature of the output oxygen, enabling the system to more accurately adjust the oxygen temperature according to actual needs and providing oxygen at an appropriate temperature for users.

[0022] Furthermore, the external machine further includes a control module. The control module is electrically connected to the power device, the refrigeration device, the processing device, and the valve device respectively. A control panel and a display are provided on the terminal machine and are connected to the control module.

[0023] By adopting the above technical solution, through the coordinated control of the control module, each device of the system can work automatically in coordination without frequent manual intervention, reducing labor costs and operation errors, improving the stability and reliability of the oxygen generation process, and enabling the diffusion oxygen generation system to continuously and stably supply oxygen. Users can conveniently operate and set the system through the control panel of the terminal machine and intuitively obtain system information through the display, realizing the convenience and intuitiveness of human-machine interaction, and enabling non-professional personnel to easily operate and monitor the diffusion oxygen generation system.

[0024] Furthermore, the gas storage device is configured as a gas storage tank. The input end of the gas storage tank is hermetically connected to a fourth one-way valve, and the output end of the gas storage tank is hermetically connected to a fourth regulating valve.

[0025] By adopting the above technical solution, the air storage tank can store a certain amount of compressed air. During the working interval of the compressor or when the gas demand of the gas-using equipment is unstable, it can continuously and stably supply gas to equipment such as the oxygen generation device, ensuring the normal operation of the entire system and avoiding equipment work interruption or abnormality caused by unstable gas source. The air storage tank can also buffer the compressed air output by the compressor, reducing air flow pulsation and pressure fluctuation, making the pressure of the compressed air more stable. And a fourth one-way valve is connected to the input end of the air storage tank, and at the same time, a one-way exhaust valve is arranged on the compression device. The use of two one-way valves plays a dual protection role, which is convenient for independent maintenance of the air storage device or the compression device and reduces the impact on the operation of the entire system.

[0026] The beneficial effects achieved: 1. The present application uses the combination of the valve device and two heat exchangers to enable the system to flexibly adjust the temperature of the output oxygen. It can provide oxygen at a suitable temperature according to different usage scenarios and requirements, improving the comfort and applicability of use. Thus, the oxygen generation function is efficiently integrated into the air conditioning system, which can not only achieve uniform diffused oxygen supply in a large space but also efficiently and conveniently adjust the air temperature.

[0027] 2. The present application uses the rotation of the rotating drum to enable each oxygen generation channel to sequentially complete processes such as air intake, oxygen generation, exhaust, and oxygen collection, realizing a continuous and uninterrupted oxygen generation function. Compared with traditional intermittent oxygen generation equipment, it can provide oxygen to the subsequent system more stably and improve the oxygen generation efficiency.

[0028] 3. The present application uses the design that the insertion cylinder is detachably inserted into the insertion cylinder seat, enabling the output pipe and the terminal machine to be conveniently connected and separated. And when the connection is disconnected, the spring can push the sealing plate to form a sealed connection with the flange, effectively preventing oxygen leakage. This can not only avoid waste of oxygen, reduce operating costs, but also prevent the accumulation of high-concentration oxygen in non-use areas and reduce safety hazards.

[0043] An embodiment of the present application discloses a diffused oxygen generation system.

[0044] Please refer to Figures 1 to 10 , in an embodiment of the present application, a diffused oxygen generation system includes an external machine 100 and a terminal machine 200. A power device 101 is installed inside the external machine 100. The power device 101 is drivingly connected to a compression device 102 and an oxygen generation device 103. The compression device 102 is connected to a gas storage device 104. The gas storage device 104 is connected to a refrigeration device 105. The refrigeration device 105 is connected to the oxygen generation device 103. The oxygen generation device 103 is connected to a processing device 106. The processing device 106 is connected to a valve device 107. A first heat exchanger 108 and a second heat exchanger 109 are respectively connected to the valve device 107. The first heat exchanger 108 is thermally connected to the compression device 102. The second heat exchanger 109 is thermally installed on the refrigeration device 105. The output end of the valve device 107 is connected to the terminal machine 200.

[0045] The implementation principle of the diffused oxygen generation system disclosed in the embodiment of the present application is as follows: First, the power device 101 in the external unit 100 is started, and the power device 101 will drive the compression device 102 and the oxygen generator 103 to work. The compression device 102 sucks in and compresses the outside air. The compressed air is transported to the gas storage device 104 for temporary storage, which plays a role in buffering and stabilizing the air pressure. Subsequently, the compressed air in the gas storage device 104 enters the refrigeration device 105. The refrigeration device 105 cools the compressed air. On the one hand, lowering the air temperature can reduce the thermal motion of gas molecules, and on the other hand, it can remove moisture in the air to achieve the purpose of drying, which is helpful for the separation of gas components in the subsequent oxygen production process. The air passing through the refrigeration device 105 enters the oxygen generator 103, and the oxygen generator 103 uses the pressure swing adsorption method to separate oxygen from the air. The separated oxygen then enters the processing device 106, which further purifies the oxygen to improve the quality of the oxygen. The processed oxygen reaches the valve device 107, which plays a role in distributing and controlling the flow direction of oxygen. When the oxygen is controlled to flow through the first heat exchanger 108, since the first heat exchanger 108 is heat-conductingly connected to the compression device 102, the heat generated by the compression device 102 during operation will be transferred to the oxygen through the first heat exchanger 108, so that the temperature of the oxygen increases. When the oxygen is controlled to flow through the second heat exchanger 109, the second heat exchanger 109 is heat-conductingly installed on the refrigeration device 105, and the low temperature of the refrigeration device 105 will be transferred to this part of the oxygen through the second heat exchanger 109, so that the temperature of the oxygen decreases. In this way, the temperature of the output oxygen can be adjusted by the valve device 107 according to actual needs. Finally, the temperature-adjusted oxygen is transported from the output end of the valve device 107 to the terminal 200, and the terminal 200 releases the oxygen into the surrounding environment in a diffused manner.

[0046] Please refer to Figures 1 to 10 In one embodiment of the present application, the power device 101 includes a motor 1011, a driving pulley 1012 is installed on the motor 1011, and the driving pulley 1012 is connected to the driven pulley 1014 through a belt 1013, and a driving shaft 1015 is installed on the driven pulley 1014. The driving shaft 1015 is installed on the compression device 102 and passes through the compression device 102. The outer side of the driving shaft 1015 is connected to the compression device 102, and the end of the driving shaft 1015 away from the driven pulley 1014 is connected to the reducer 1016, and the reducer 1016 is connected to the oxygen generator 103.

[0047] During operation, the motor 1011 serves as the power source of the entire power device 101, and starts to operate after the power is turned on. When the motor 1011 is in operation, it drives the driving pulley 1012 installed thereon to rotate synchronously. The driving pulley 1012 transmits power to the driven pulley 1014 through the belt 1013. Since the belt transmission has a certain flexibility, it can buffer vibration and impact to a certain extent, ensuring the stability of power transmission. After the driven pulley 1014 obtains power, it starts to rotate, thereby driving the drive shaft 1015 connected thereto to rotate. The drive shaft 1015 is installed on the compression device 102 and passes through the device, and its outer side is connected to the compression device 102 in a transmission connection. As the drive shaft 1015 rotates, power is transmitted to the compression device 102 to compress the air. A reducer 1016 is connected to the end of the drive shaft 1015 away from the driven pulley 1014 in a transmission connection. The power after speed regulation and torque increase by the reducer 1016 is transmitted to the oxygen generator 103, driving the oxygen molecular sieve inside the oxygen generator 103 to work, thereby completing the process of separating oxygen from the air.

[0048] Please refer to Figures 1 to 10 In one embodiment of the present application, the compression device 102 is configured as a compressor 1021; the compressor 1021 includes a body 1022, on which three compression cylinders 1023 are installed, and a cylinder cover 1024 is installed on the end of the compression cylinder 1023 away from the body 1022, and a piston body 1025 is sealed and slidably connected inside the compression cylinder 1023, and a drive shaft 1015 passes through the outer side of the body 1022 and is fixedly installed with a cam 1026, and the end of the piston body 1025 close to the cam 1026 is fixedly connected to a push rod 1027, and the end of the piston body 1025 close to the cylinder cover 1024 is fixedly connected to a return spring 1028, and a one-way intake valve 1029 and a one-way exhaust valve 10210 are installed on the cylinder cover 1024, and the one-way intake valve 1029 is connected to a filter 10211, and the one-way exhaust valve 10210 is connected to the gas storage device 104.

[0049] During operation, the drive shaft 1015 starts to rotate under the drive of the power device 101, and the cam 1026 fixedly mounted on the drive shaft 1015 rotates synchronously. As the cam 1026 rotates, its profile continuously pushes the push rod 1027, thereby causing the piston body 1025 connected to the push rod 1027 to slide in the compression cylinder 1023 in a sealed manner.

[0050] When the cam 1026 rotates to make the push rod 1027 be pushed to the farthest position, the piston body 1025 moves toward the cylinder cover 1024, and the space in the compression cylinder 1023 is reduced; when the cam 1026 continues to rotate, the push rod 1027 is no longer pushed by the cam 1026. At this time, the return spring 1028 takes effect, pulling the piston body 1025 back to the initial position, and the space in the compression cylinder 1023 increases.

[0051] When the piston body 1025 moves away from the cylinder head 1024 under the action of the return spring 1028, the volume of the compression cylinder 1023 increases and the air pressure decreases. Under the action of the external atmospheric pressure, after the air passes through the filter 10211 to filter out the impurities, it enters the compression cylinder 1023 through the one-way intake valve 1029. The function of the one-way intake valve 1029 is to ensure that the air can only enter the compression cylinder 1023 unidirectionally and prevent the air from flowing back during the compression process. When the piston body 1025 moves towards the cylinder head 1024 under the push of the cam 1026, the air in the compression cylinder 1023 is compressed and the air pressure increases. When the air pressure rises to a certain level, the one-way exhaust valve 10210 opens, and the compressed air is discharged into the air storage device 104 through the one-way exhaust valve 10210. The one-way exhaust valve 10210 also ensures that the air can only be discharged unidirectionally and prevents the compressed air in the air storage device 104 from flowing back into the compression cylinder 1023.

[0052] Please refer to Figures 1 to 10 In an embodiment of the present application, the oxygen generation device 103 includes a rotating cylinder 1031. The two ends of the rotating cylinder 1031 are hermetically and rotatably connected with end seats 1032. A rotating shaft 1033 passing through the end seats 1032 is fixedly connected to the center of the rotating cylinder 1031. The rotating shaft 1033 is in transmission connection with the power device 101. A plurality of annularly and evenly distributed oxygen generation channels 1034 are axially formed on the rotating cylinder 1031. Oxygen generation molecular sieves 1035 are installed inside the oxygen generation channels 1034. First through holes 1036, second through holes 1037, third through holes 1038, and fourth through holes 1039 are respectively formed at both ends of the oxygen generation channels 1034 on the two end seats 1032. The first through holes 1036 and the second through holes 1037 are symmetrically arranged, and the third through holes 1038 and the fourth through holes 1039 are symmetrically arranged. An intake pipe 10310 is hermetically and fixedly installed on the first through hole 1036. The intake pipe 10310 is connected to the refrigeration device 105. An exhaust pipe 10311 is hermetically and fixedly installed on the second through hole 1037. A first regulating valve 10312 is installed on the exhaust pipe 10311. A three-way pipe 10313 is hermetically and fixedly installed on the third through hole 1038. A connecting pipe 10314 is hermetically and fixedly installed on the fourth through hole 1039. A first one-way valve 10315 is hermetically installed between the connecting pipe 10314 and the three-way pipe 10313. The other end of the three-way pipe 10313 is connected to an oxygen pipe 10316. The oxygen pipe 10316 is connected to the processing device 106.

[0053] During the working process, the power device 101 drives the rotating shaft 1033 to rotate through transmission. The rotating shaft 1033 is fixed at the center of the rotating cylinder 1031, so that the rotating cylinder 1031 rotates in a sealed manner between the end seats 1032 at both ends. The low-temperature compressed air output by the refrigeration device 105 enters the first through-hole 1036 through the air inlet pipe 10310. Due to the rotation of the rotating cylinder 1031, when the oxygen generation channel 1034 is communicated with the first through-hole 1036, the compressed air enters the inside of the oxygen generation channel 1034. An oxygen generation molecular sieve 1035 is installed in the oxygen generation channel 1034. When the compressed air flows through the oxygen generation molecular sieve 1035, the molecular sieve has a strong adsorption effect on gases such as nitrogen and carbon dioxide in the air, while oxygen is relatively less adsorbed, thus realizing the separation of oxygen from other gases, and an oxygen-rich gas is obtained in the oxygen generation channel 1034. As the rotating cylinder 1031 continues to rotate, when the oxygen generation channel 1034 is communicated with the second through-hole 1037, the waste gases such as nitrogen adsorbed by the oxygen generation molecular sieve 1035 are discharged through the exhaust pipe 10311. The first regulating valve 10312 can adjust the flow rate and pressure of the waste gas discharge. When the oxygen generation channel 1034 is communicated with the third through-hole 1038, the oxygen-rich gas in the oxygen generation channel 1034 enters the oxygen pipe 10316 through the three-way pipe 10313, and then is transported to the processing device 106 for further processing. At the same time, in order to improve the efficiency of discharging the waste gases such as nitrogen adsorbed by the oxygen generation molecular sieve 1035 through the exhaust pipe 10311, a first one-way valve 10315 is installed between the connecting pipe 10314 and the three-way pipe 10313, so that part of the oxygen-rich gas flows from the oxygen generation channel 1034 to the exhaust pipe 10311 again, realizing the cleaning of the oxygen generation molecular sieve 1035.

[0054] Please refer to Figures 1 to 10 , in an embodiment of the present application, the gas storage device 104 is configured as a gas storage tank 1041. A fourth one-way valve 1042 is hermetically connected to the input end of the gas storage tank 1041, and a fourth regulating valve 1043 is hermetically connected to the output end of the gas storage tank 1041.

[0055] During the working process, the compressed air generated by the compression device 102 is discharged through the one-way exhaust valve 10210 and enters the gas storage tank 1041 from the fourth one-way valve 1042. The compressed air entering the gas storage tank 1041 is stored, and a certain air pressure is formed in the gas storage tank 1041 to provide a stable gas source for subsequent oxygen generation and other links. When subsequent equipment such as the oxygen generation device 103 needs to use gas, the fourth regulating valve 1043 is opened, and the compressed air in the gas storage tank 1041 is discharged through the fourth regulating valve 1043 under the action of the air pressure.

[0056] Please refer to Figures 1 to 10, in an embodiment of the present application, the refrigeration device 105 includes a refrigerator 1051. The refrigerator 1051 is connected to a hermetically sealed cooling box 1052. A drain valve is installed at the bottom of the cooling box 1052. The second heat exchanger 109 is hermetically installed inside the cooling box 1052.

[0057] During the working process, when the refrigerator 1051 is started and starts the refrigeration work, a low-temperature environment will be formed inside the cooling box 1052. The refrigerator 1051 can adopt common refrigeration technologies such as compression refrigeration and semiconductor refrigeration, and absorb heat through the refrigeration cycle process to reduce its own temperature. The air compressed by the compression device 102 flows from the gas storage device 104 into the cooling box 1052. According to the physical properties of air, when the compressed air is cooled, its ability to hold water vapor decreases, and the water vapor originally present in the air in gaseous form will reach a supersaturated state and then condense into liquid water. These liquid waters will accumulate at the bottom of the cooling box 1052. By opening the drain valve, the condensed water can be discharged from the cooling box 1052 to achieve the drying treatment of the compressed air. At the same time, the oxygen output from the processing device 106 passes through the second heat exchanger 109, which can enable the oxygen to exchange heat with the low-temperature environment inside the cooling box 1052, thereby reducing the oxygen temperature to adjust the temperature of the output oxygen.

[0058] Please refer to Figures 1 to 10 , in an embodiment of the present application, the processing device 106 includes a filtration module and a disinfection module, and the filtration module and the disinfection module are connected in series in sequence.

[0059] During the working process, when the gas passes through the filtration module, the filter screen, filter membrane or porous filtering material therein will intercept impurities such as solid particles and suspended matters larger than the pore size according to their pore sizes, so that these impurities cannot pass through the filter layer, thereby realizing the separation from the fluid. In addition, some filtering materials also have an adsorption effect and can adsorb some soluble impurities and colloids in the fluid to further improve the filtering effect, preliminarily purify the fluid and reduce its impurity content. After the filtration module preliminarily purifies the fluid, the filtered fluid enters the disinfection module. The disinfection module mainly uses physical, chemical or biological methods to kill or inhibit harmful pathogens such as bacteria, viruses and microorganisms in the fluid.

[0060] Please refer to Figures 1 to 10, in an embodiment of the present application, the valve device 107 includes a valve installation box 1071. Inside the valve installation box 1071, an input pipe 1072 and an output pipe 1073 are installed. The outside of the output pipe 1073 is coated with heat-insulating material; at one end of the input pipe 1072 inside the valve installation box 1071, a second regulating valve 1074 and a third regulating valve 1075 are installed in parallel. One end of the input pipe 1072 outside the valve installation box 1071 is connected to the processing device 106; at one end of the output pipe 1073 inside the valve installation box 1071, a second check valve 1076 and a third check valve 1077 are installed in parallel. One end of the output pipe 1073 outside the valve installation box 1071 is connected to the terminal 200; the first heat exchanger 108 is connected in series between the second regulating valve 1074 and the second check valve 1076, and the second heat exchanger 109 is connected in series between the third regulating valve 1075 and the third check valve 1077.

[0061] During the working process, the oxygen processed by the processing device 106 enters the inside of the valve installation box 1071 through the input pipe 1072. The second regulating valve 1074 and the third regulating valve 1075 installed in parallel on the input pipe 1072 can respectively control the oxygen flow rate entering different paths.

[0062] Part of the oxygen enters the first heat exchanger 108 through the second regulating valve 1074. The first heat exchanger 108 is thermally connected to the compression device 102, and uses the heat generated during the operation of the compression device 102 to heat the oxygen. The heated oxygen then enters the output pipe 1073 through the second check valve 1076. The second check valve 1076 ensures that the oxygen can only flow in one direction and prevents backflow.

[0063] Another part of the oxygen enters the second heat exchanger 109 through the third regulating valve 1075. The second heat exchanger 109 is thermally connected to the refrigeration device 105, and uses the low temperature of the refrigeration device 105 to cool the oxygen. The cooled oxygen then enters the output pipe 1073 through the third check valve 1077. Similarly, the third check valve 1077 ensures the one-way flow of oxygen. The heated oxygen and the cooled oxygen entering the output pipe 1073 are mixed inside the output pipe 1073. By adjusting the opening degrees of the second regulating valve 1074 and the third regulating valve 1075, the flow rate ratio of the oxygen entering the two paths can be controlled, thereby adjusting the temperature of the output oxygen.

[0064] Finally, the oxygen with adjusted temperature is transported to the terminal 200 through the output pipe 1073. The heat-insulating material coated on the outside of the output pipe 1073 can reduce the heat dissipation of the oxygen during transportation and ensure the stability of the output oxygen temperature.

[0065] Please refer to Figures 1 to 10, in an embodiment of the present application, the first heat exchanger 108 includes a first heat exchange tube 1081 made of a heat-conducting material. The first heat exchange tube 1081 is spirally wound around the compression device 102. The input end of the first heat exchange tube 1081 is hermetically connected to a heat exchange input tube 1082, and the output end of the first heat exchange tube 1081 is hermetically connected to a heat exchange output tube 1083. The outside of the heat exchange output tube 1083 is coated with heat-insulating material.

[0066] During the working process, when the compression device 102 compresses air, mechanical energy is converted into the internal energy of the air, causing the temperature of the compression device 102 itself to rise. The first heat exchange tube 1081 is made of a heat-conducting material and spirally wound around the compression device 102. Such a design increases the contact area with the compression device 102, which is beneficial to heat transfer. When the oxygen to be heated flows into the first heat exchange tube 1081 from the heat exchange input tube 1082, the heat of the compression device 102 will be transferred to the fluid in the first heat exchange tube 1081 through the heat-conducting material, realizing the heating of oxygen.

[0067] Please refer to Figures 1 to 10 , in an embodiment of the present application, the second heat exchanger 109 includes a second heat exchange tube 1091. The second heat exchange tube 1091 is serpentinely coiled inside the refrigeration device 105. The input end of the second heat exchange tube 1091 is hermetically connected to a heating input tube 1092, and the output end of the second heat exchange tube 1091 is hermetically connected to a heating output tube 1093. The outside of the heating output tube 1093 is coated with heat-insulating material.

[0068] During the working process, after the refrigeration device 105 is started, a low-temperature environment is formed inside it. The oxygen output from the oxygen generation device enters the second heat exchange tube 1091 through the heating input tube 1092. The second heat exchange tube 1091 is serpentinely coiled inside the refrigeration device 105. This design greatly increases the residence time of oxygen in the low-temperature environment and the contact area with the low-temperature environment. When the oxygen flows in the second heat exchange tube 1091, according to the principle of heat transfer, the high-temperature oxygen exchanges heat with the low-temperature internal environment of the refrigeration device 105, and the heat in the oxygen is transferred to the refrigeration device 105, thereby reducing the temperature of the oxygen.

[0069] Please refer to Figures 1 to 10 , in an embodiment of the present application, the external machine 100 further includes a control module 110. The control module 110 is electrically connected to the power device 101, the refrigeration device 105, the processing device 106, and the valve device 107 correspondingly. A control panel 202 and a display 203 connected to the control module 110 are provided on the terminal 200.

[0070] During the working process, as the control core of the outdoor unit 100, the control module 110 is electrically connected to the power device 101, the refrigeration device 105, the processing device 106, and the valve device 107, and can receive the information fed back by each device, such as the operating state of the power device, the temperature parameters of the refrigeration device, the working progress of the processing device, the opening and closing degree of the valve device, etc. At the same time, according to the preset programs and parameters, the control module 110 sends instructions to these devices to coordinate their work and ensure the stable and efficient operation of the entire oxygen diffusion system. The control panel 202 on the terminal 200 can be used for users to input operation instructions, such as setting parameters such as oxygen generation concentration and flow rate, and these instructions will be transmitted to the control module 110. The control module 110 makes corresponding adjustments to the system according to the received instructions. At the same time, the control module 110 will transmit information such as the operating state of the system and oxygen generation data to the display 203 of the terminal 200 so that users can understand the working conditions of the system in real time, such as the current oxygen generation flow rate and the equipment operation time.

[0071] Please refer to Figures 1 to 10 , in an embodiment of the present application, the terminal 200 includes a housing 201. Inside the housing 201, a water storage tank 204 is installed. A tank cover 205 is hermetically installed on the water storage tank 204. An inlet box 206 is hermetically connected to the outside of the water storage tank 204 near the tank cover 205. One end of the inlet box 206 passing through the side wall of the housing 201 is hermetically slidably connected to an inlet drawer 207. An inlet 208 is provided on the inlet drawer 207. A gas guide box 209 connected to the output pipe 1073 is fixedly and hermetically installed inside the tank cover 205 within the water storage tank 204. An atomizer 210 connected to the water storage tank 204 is fixedly installed inside the gas guide box 209. The upper end of the atomizer 210 passes through the tank cover 205. The tank cover 205 is provided with a gas guide cylinder 211 corresponding to the gas guide box 209. An exhaust hood 212 is installed on the top of the housing 201 corresponding to the atomizer 210 and the gas guide cylinder 211.

[0072] During the working process, the user can inject water into the water inlet drawer 207. The water flows into the water inlet box 206 through the water inlet 208, and then the water inlet box 206 is hermetically connected to the water storage tank 204 to replenish the water source for the water storage tank 204. This drawer-type water inlet design is convenient for the user to operate and ensures good sealing to prevent water leakage. The oxygen after being temperature-regulated by the valve device 107 is transported to the air guide box 209 through the output pipe 1073. The air guide box 209 plays a role in stabilizing the oxygen gas flow and pressure, enabling the oxygen to be evenly diffused and output. The humidified oxygen rises through the air guide cylinder 211 to the lower part of the exhaust hood 212. The water in the water storage tank 204 also forms water mist through the atomizer 210 and rises to the lower part of the exhaust hood 212. The water mist formed by the atomizer 210 is fully mixed with the oxygen to achieve the humidification treatment of the oxygen. The humidified oxygen is discharged from the exhaust hood 212. In this way, by making the oxygen more humid, it is beneficial for the absorption and utilization of the human respiratory tract, providing the user with humid and oxygen-rich air.

[0073] Please refer to Figures 1 to 10 , in an embodiment of the present application, a gas guide pipe 213 penetrating the water storage tank 204 is fixedly connected to the air guide box 209. One end of the gas guide pipe 213 far from the air guide box 209 is fixedly connected with an insertion cylinder seat 214. A push rod 215 is fixedly installed inside the insertion cylinder seat 214. One end of the output pipe 1073 far from the valve installation box 1071 is correspondingly installed with an insertion cylinder 216 inside the insertion cylinder seat 214. The insertion cylinder 216 is detachably inserted inside the insertion cylinder seat 214. A sealing plate 217 is slidably connected to the inside of the insertion cylinder 216 corresponding to the push rod 215. A flange 218 is provided at the outer end of the insertion cylinder 216 corresponding to the end face of the sealing plate 217. A spring 219 abutting against the inner end face of the sealing plate 217 is installed inside the insertion cylinder 216. The spring 219 pushes the sealing plate 217 to form a sealed connection between the outer end face of the sealing plate 217 and the flange 218.

[0074] During the working process, when the insertion cylinder 216 of the output pipe 1073 is inserted into the insertion cylinder seat 214, the push rod 215 inside the insertion cylinder seat 214 will push open the sealing plate 217. The sealing plate 217, which was originally in a sealed connection with the flange 218 under the action of the spring 219, slides towards the inside of the insertion cylinder 216 against the elastic force of the spring 219 under the push of the push rod 215, breaking the seal between the sealing plate 217 and the flange 218. At this time, the oxygen regulated by the valve device 107 can smoothly enter the air guide box 209 from the output pipe 1073 through the insertion cylinder 216, the insertion cylinder seat 214, and the gas guide pipe 213, and then participate in the subsequent humidification and discharge processes.

[0075] When it is necessary to disconnect the output pipe 1073 from the terminal 200, the insertion cylinder 216 is pulled out from the insertion cylinder seat 214. The ejector rod 215 no longer exerts a thrust on the sealing plate 217, and the spring 219 restores its elastic deformation, pushing the sealing plate 217 to slide towards the flange 218 until the two form a sealed connection again. This can prevent the leakage of oxygen in the output pipe 1073, and at the same time avoid the entry of external dust, debris, etc. into the interior of the output pipe 1073.

[0076] With the design that the insertion cylinder 216 is detachably inserted inside the insertion cylinder seat 214, the connection and disconnection operations between the output pipe 1073 and the terminal 200 are very convenient. During the installation, maintenance or movement of the equipment, the connection and disassembly of the output pipe 1073 can be quickly completed, improving the work efficiency and reducing the operation difficulty. When disconnecting, the spring 219 pushes the sealing plate 217 to form a sealed connection with the flange 218, effectively preventing the leakage of oxygen in the output pipe 1073. This can not only avoid the waste of oxygen and reduce the operating cost, but also prevent the accumulation of high-concentration oxygen in non-use areas and reduce potential safety hazards.

[0077] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
