Description

Technical Field

[0001] The present application relates to the technical field of vehicle air intake and exhaust, and in particular to a vehicle dual oxygen supply system. Background Art

[0002] Cars are an indispensable means of transportation for people to travel, and the comfort of car rides has also attracted more attention. For safety, comfort and noise reduction, cars usually keep their windows closed when driving at high speeds, making the interior of the car (especially buses and public buses) a crowded space. The advent of the air-conditioning system has improved the riding environment and can cool, heat, defrost, defog and humidify the interior of the car. However, since human breathing consumes oxygen and exhales carbon dioxide, the oxygen content in a closed compartment with untimely air exchange can easily decrease, causing passengers to become drowsy when riding on the bus, and even affecting their health. Especially since the outbreak of the new crown epidemic, passengers need to wear masks when riding in public transportation, which further reduces the amount of oxygen inhaled. According to some data, the breathing volume of each adult in 24 hours is 10m 3 Air, the volume oxygen content of air is 21%, 10m 3 The oxygen content of air is 2.1m 3 0.525m3 of which is consumed daily through breathing 3 Oxygen, exhaled about 0.458m 3 Carbon dioxide, calculated, each time the oxygen is inhaled about 25% is used, and the other 75% is exhaled. Take a 50-seat bus as an example, the space inside the bus is about 50m 3 (Under normal circumstances, oxygen content is 10.5m 3 ), 50 passengers breathe 20.8m of air per hour 3 (oxygen content 4.4m 3 ), oxygen consumption is 1.1m 3 , which means that in just one hour, the oxygen content in the car has increased from 10.5m 3 Down to 9.4m 3 , that is, the oxygen content drops from 21% to 18.8%. This is fatal for buses that travel for several hours to dozens of hours. Even with fresh air, it is still not enough to offset the oxygen consumption in the closed compartment. Oxygen-rich air must be added to maintain the 21% oxygen content in the compartment. In addition, when a car travels long distances to high altitude areas, due to the high altitude, thin air, low oxygen content, and reduced air intake, it is easy to have problems such as insufficient oxygen supply in the car and incomplete engine combustion. Incomplete engine combustion will affect the driver's driving performance, so it is very important to ensure oxygen supply in the car and the engine compartment.

[0003] At the same time, it should be noted that excessive oxygen content in the car can also cause oxygen intoxication, destroy the alveolar capillary barrier structure, and cause cilia dysfunction. In view of the small amount of oxygen required for oxygenation in the car compartment and the low purity of oxygen, methods such as deep air separation, membrane separation, and pressure swing adsorption to produce pure or high-purity oxygen are not applicable.

[0004] The vehicle oxygen enrichment device or oxygen supply device in the prior art has a limited oxygen production capacity, high cost, cannot achieve continuous oxygen supply, and cannot adjust the oxygen supply according to changes in the oxygen supply demand in the vehicle. It cannot ensure the long-term operation stability of the engine, cannot ensure the airtightness of the vehicle when oxygen supply is not needed, and cannot cooperate well with the air conditioning system in the vehicle.

By providing the one-way fans 183 and the first one-way valve 184, it can be ensured that the fresh air forms a stable laminar flow in the air inlet channel 181 without turbulence, thereby ensuring the continuity and stability of the air flow before oxygen supply. The filter 182 is provided to filter the fresh air, thereby ensuring the air quality during oxygen supply.

[0036] Reference Figure 2-4, the piston plate 13 is provided with a first air passage 131, and the inner side of the cylinder body 12 is provided with a second air passage 123; when the piston plate 13 moves to contact with the L-shaped rod 17, the first air passage 131 is connected with the second air passage 123. In the embodiment of the present application, it is taken into consideration that a large amount of oxygen is needed in the vehicle, and the air intake through the through hole of the piston plate 13 alone cannot meet the oxygen supply in the vehicle, so the first air passage 131 and the second air passage 123 are provided to increase the air flow through the piston plate 13. During actual oxygen supply, when the piston plate 13 moves and the sealing plug 14 is pushed open by the L-shaped rod 17, at this time, when the fresh air enters the vehicle after passing through the through hole, it is still not enough to meet the oxygen supply demand in the vehicle, and it is necessary to continue to increase the speed of the first fan 11, and then the fresh air continues to squeeze the piston plate 13 to move. Finally, after the piston plate 13 is squeezed against the L-shaped rod 17, the piston plate 13 no longer moves, and the first air channel 131 on the piston plate 13 is connected to the second air channel 123 on the inner wall of the cylinder 12. Another part of the fresh air passes through the first air channel 131 and the second air channel 123 and then passes through the piston plate 13, thereby increasing the amount of fresh air passing through the piston plate 13, so as to meet the oxygen supply to the vehicle. When a large amount of oxygen is not needed in the vehicle, the moving position of the piston plate 13 will not contact the L-shaped rod 17. At this time, the first air channel 131 is not connected to the second air channel 123, and the oxygen supply in the vehicle can be met only by the flow of fresh air through the through hole after the sealing plug 14 is pushed open.

In the embodiment of the present application, a heat dissipation device 22 is further provided, mainly to ensure effective heat dissipation of the condenser 92, thereby improving the refrigeration effect of the air conditioner, and ultimately facilitating the cooling of the fresh air when supplying oxygen to the vehicle, so that the oxygen supply in the vehicle and the air conditioning system 9 work well together; during actual heat dissipation, the cooled air in the first oxygen-depleted channel 3 is first transported to the condenser 92, and the condenser 92 fan continuously blows air to the condenser 92 for heat dissipation, so that the cooled air in the first oxygen-depleted channel 3 is further utilized, so that the cooled air in the first oxygen-depleted channel 3 performs the first heat dissipation on the condenser 92, and then the heat generated by the condenser 92 is aggregated and collected by the air collecting hood 221 and rises circuitously into the spiral pipe 222, and the evaporator 9 is cooled. The condensed water generated at 1 is transported to the top of the spiral pipe 222 through the first condensation pipe 224, and descends from top to bottom into the spiral pipe 222, and realizes heat exchange with the hot air that rises in a roundabout way by counter-convection, so that the condensed water generated at the evaporator 91 can be well reused to realize the second cooling and heat dissipation of the condenser 92. After the hot air exchanges heat with the condensed water, it is finally discharged out of the vehicle from the top of the spiral pipe 222, and the condensed water is drained out of the vehicle from the exhaust pipe 225 at the bottom of the spiral pipe 222. An exhaust pump 223 is arranged at the top of the spiral pipe 222 to extract the hot air in the spiral pipe 222, so as to avoid the hot air from accumulating in large quantities at the air collecting hood 221, thereby effectively improving the heat dissipation of the condenser 92.

[0038] Reference Figure 1 , 5The heat dissipation device 22 also includes a water collecting tank 226, a second condensing pipeline 227 and a refrigeration block 228; the air collecting hood 221, the spiral pipeline 222 and the second condensing pipeline 227 are all in the water collecting tank 226, and the air collecting hood 221 is sealed and connected to the inner bottom surface of the water collecting tank 226; the first condensing pipeline 224 extends into the water collecting tank 226 and is provided with an overflow port 23 on the side of the tube body; the second condensing pipeline 227 is vertically arranged and connected to the overflow port 23; the refrigeration block 228 is arranged in the water collecting tank 226; and a drain port 24 is provided on the side of the water collecting tank 226. In the embodiment of the present application, it is further considered that if the condensate flow rate is large, the spiral pipe 222 may be filled up, which is not conducive to the rise of hot air from the spiral pipe 222. Therefore, a water collecting tank 226 and a second condensate pipe 227 are further provided, that is, an overflow port 23 is opened in the upper area of ​​the outer side of the pipe wall of the first condensate pipe 224. The structure of the overflow port 23 is a groove-shaped through-port, and the second condensate pipe 227 is vertically connected at the overflow port 23. When the condensate flow rate in the first condensate pipe 224 is large and exceeds the height of the overflow port 23, the excess condensate will overflow from the overflow port 23 to the second condensate pipe 227, and finally drip into the water collecting tank 226 for collection. When the condensate in the water collecting tank 226 is collected, it can cool down and dissipate the heat of the outside of the air collecting hood 221 and the spiral pipe 222, thereby making the overflow This part of the condensed water in the flow can also be utilized. At this time, the hot air entering the spiral pipe 222 exchanges heat with the condensed water entering the spiral pipe 222 inside the spiral pipe 222, and the outside of the spiral pipe 222 exchanges heat again through the condensed water collected in the water collecting tank 226, thereby realizing the third cooling and heat dissipation of the condenser 92. At the same time, a refrigeration block 228 is further arranged in the water collecting tank 226, so that the condensed water in the water collecting tank 226 after heat exchange with the outside of the spiral pipe 222 is cooled, so that the condensed water in the water collecting tank 226 can continue to be used for cooling the spiral pipe 222. Finally, when there is too much condensed water collected in the water collecting tank 226, it overflows and is discharged from the drain port 24 to avoid overfilling of the water collecting tank 226. The refrigeration block 228 uses a chemical heat-absorbing material that is easy to replace, and is replaced regularly after a period of use.

[0039] Reference Figure 1 , 6-7, a vehicle dual oxygen supply system provided in an embodiment of the present application also includes a diverter device 25; the diverter device 25 includes an air outlet channel 251, a first wind shield 252, a second wind shield 253, a rotating shaft 254, a plurality of fan blades 255 and a plurality of diverter plates 256; the air outlet channel 251 is connected to the output end of the first oxygen-enriched channel 2, and the air outlet channel 251 passes through the first wind shield 252 and is fixedly connected to the first wind shield 252; the second wind shield 253 is arranged directly above the first wind shield 252, and is rotatably connected to the rotating shaft 254; a plurality of fan blades 255 are arranged in a ring array on the outside of the rotating shaft 254 and are fixedly connected to the rotating shaft 254; a plurality of diverter plates 256 are arranged in a ring array, and are respectively fixedly connected to the end faces of the plurality of fan blades 255 facing away from the second wind shield 253. In the embodiment of the present application, it is further considered that since the present application adopts the method of supplying oxygen into the vehicle through the first oxygen-enriched channel 2 with an external magnetic field, compared with the method of supplying oxygen into the vehicle through a conventional oxygen generator, under the premise of the same oxygen supply demand into the vehicle, the air flow rate passing through the first oxygen-enriched channel 2 of the present application per unit time is greater than the air flow rate passing through the conventional oxygen generator per unit time when supplying oxygen. Therefore, the embodiment of the present application further provides a diversion device 25, the purpose of which is to avoid a certain impact on the passengers caused by a large air flow entering the vehicle, thereby affecting the comfort level in the vehicle; when the gas in the first oxygen-enriched channel 2 is output, it first enters the air outlet channel 2 51, and then vertically impacts between the first wind deflector 252 and the second wind deflector 253, so that the large impact force of the airflow drives the multiple fan blades 255 to rotate, and the rotation of the fan blades 255 drives the multiple diverter plates 256 to rotate, and the rotation of the diverter plates 256 generates a tangential driving force on the airflow, so that the airflow is evenly dispersed and pushed tangentially to all directions, achieving the effect of evenly diverting the airflow to all directions, avoiding the impact force of the large airflow directly passing through the car on the passengers, and can evenly divert the airflow to all directions, so as to ensure that most areas in the car can basically get oxygen supply at the same time, while ensuring the comfort of the car.

[0040] Reference Figure 1 The flow splitting device 25 further includes a plurality of flow splitting blades 257; the plurality of flow splitting blades 257 are arranged at intervals above the second windshield 253. In the embodiment of the present application, a plurality of flow splitting blades 257 are further arranged, so that the airflow blocked by the second windshield 253 and detoured to all directions can be further dispersed to most areas in the vehicle through the plurality of flow splitting blades 257, thereby improving the uniformity of airflow dispersion when supplying oxygen in the vehicle.

[0041] Reference Figure 1, the second one-way valve 31 and the third one-way valve 71 are respectively arranged in the input ends of the first oxygen-depleted channel 3 and the second oxygen-depleted channel 7. In the embodiment of the present application, the second one-way valve 31 is arranged to ensure that the gas entering the first oxygen-depleted channel 3 will not flow back into the vehicle when there is no external magnetic field in the first oxygen-rich channel 2, that is, when oxygen supply is not required, and to further improve the stability of the overall oxygen supply in the vehicle. By arranging the third one-way valve 71, the purpose is to ensure that the gas in the second oxygen-depleted channel 7 will not flow back. The cross-sectional area ratio of the first oxygen-rich channel 2 to the first oxygen-depleted channel 3 is 9:1~8:2. In the embodiment of the present application, it is considered that if the oxygen content in the air is increased by 2%, at least 10% of N2 needs to be divided. Considering that the first magnet 4 may not be able to absorb all O2 into the vehicle, if 50% escapes with N2, 20% of N2 (or oxygen-depleted air) needs to be divided. Therefore, the cross-sectional area ratio of the first oxygen-rich channel 2 to the first oxygen-depleted channel 3 is set to 9:1~8:2.

[0042] Reference Figure 8 , through the structural design provided in the embodiment of the present application, the inertial force on the oxygen molecules and the magnetic field force on them are basically balanced, and the oxygen molecules can easily pass through the magnetic field channel into the car instead of being attracted to the surface of the magnetic pole. At the same time, due to the difference in oxygen concentration between the car and the magnetic channel, the concentration difference makes the oxygen diffuse further into the car. When using permanent magnets, since the magnetic field strength cannot be adjusted, the oxygen concentration is adjusted by adjusting the air intake of the first fan 11 according to the oxygen concentration detected in the car; in addition, since the magnetization intensity of oxygen is related to temperature, the oxygen concentration can also be adjusted by adjusting the speed of the compressor 94. When using electromagnets, in addition to the above two methods, the purpose of adjusting the oxygen concentration can also be achieved by adjusting the coil current. This system can still be used during the heating process. Since the magnetization intensity of oxygen decreases when the temperature is high, the amount of O2 escaping with N2 increases. It is necessary to adjust the air intake of the first fan 11 or increase the current of the magnetization coil to further adapt to the change in oxygen concentration. In order to generate an uneven magnetic field, the permanent magnet or electromagnet is connected in parallel in multiple stages, the magnetic field intensity of each permanent magnet gradually decreases, and the number of coils of each electromagnet gradually decreases.

[0043] The working principle of a vehicle dual oxygen supply system provided in an embodiment of the present application is as follows:

[0044] When oxygen is needed in the car, the internal damper 19 is closed and the external damper 10 is opened. The oxygen concentration sensor 20 detects that the oxygen concentration in the car is insufficient and sends a signal to the controller 21. Then the controller 21 controls the first fan 11 to start. The fresh air is drawn by the first fan 11 and filtered through the filter 182. After passing through multiple one-way fans 183 and the first one-way valve 184, the fresh air forms a stable laminar flow in the air inlet channel 181 without turbulence, ensuring the continuity and stability of the air flow before oxygen supply. Then, after passing through the first fan 11, it enters the cylinder 12 from the inlet 121. The incoming fresh air squeezes the piston plate 13 so that the piston plate 13 slides in the cylinder 12 until the sealing plug 14 in the center of the piston plate 13 moves to contact the L-shaped When the rod 17 is pushed open, the sealing plug 14 is pushed open from the through hole, so that the cylinders 12 on both sides of the piston plate 13 are connected, and then the fresh air passes through the through hole and leaves the cylinder 12 from the outlet 122, and finally passes through the first oxygen-enriched channel 2 to realize oxygen supply in the vehicle, wherein the first fan 11 can adjust its wind pressure according to the demand for oxygen supply in the vehicle, so that the size of the opening of the sealing plug 14 pushed open changes accordingly, and finally the oxygen supply demand in the vehicle and the air intake reach a balanced state, ensuring the stability of the oxygen content in the vehicle, wherein when the gas in the first oxygen-enriched channel 2 is output, it will enter the air outlet channel 251, and then vertically impact between the first windshield 252 and the second windshield 253, so that the large impact force of the airflow drives the multiple fan blades 255 The fan blades 255 rotate, and the plurality of diverter plates 256 are driven to rotate at the same time. The rotation of the diverter plates 256 generates a tangential driving force on the airflow, thereby evenly dispersing the airflow and tangentially pushing it to all directions, achieving the effect of evenly diverting the airflow to all directions, avoiding the impact of the faster airflow directly entering the car on the passengers, and evenly diverting the airflow to all directions, thereby ensuring that most areas in the car can basically get oxygen supply at the same time, and ensuring the comfort level in the car; when oxygen supply is not needed, the first fan 11 no longer works, and the piston plate 13 returns to its original position under the action of the first elastic member 15, and the sealing plug 14 is reset and blocks the through hole under the action of the second elastic member 16, ensuring the airtightness of the cylinder 12. The airtightness of the vehicle is ensured; the oxygen concentration in the vehicle compartment is detected by the in-vehicle oxygen concentration sensor 20, and the oxygen concentration is fed back to the controller 21. The controller 21 adjusts the speed of the compressor 94, the speed of the first fan 11 and the current of the electromagnet (if an electromagnet is used) according to the feedback result to ensure that oxygen deficiency and oxygen intoxication do not occur in the vehicle compartment; when the vehicle runs to an area with a higher altitude and needs to supply oxygen to the engine compartment 26, the control valve 52 is opened, and the second fan 51 is controlled to start at the same time, and fresh air is drawn from the external damper 10 to the input ends of the second oxygen-rich channel 6 and the second oxygen-poor channel 7, and the paramagnetic oxygen enters the second oxygen-rich channel 6 to supply oxygen to the engine compartment 26, and the antimagnetic nitrogen enters the second oxygen-poor channel 7 and is finally discharged outside the vehicle;If the vehicle and the engine compartment 26 need oxygen supply at the same time, the first fan 11 and the second fan 51 are turned on respectively, and fresh air is extracted from the external damper 10 by the first fan 11 and the second fan 51, and oxygen is supplied to the vehicle and the engine compartment 26 respectively through the first oxygen-enriched channel 2 and the second oxygen-enriched channel 6. ;

[0045] In the embodiment of the present application, when the oxygen concentration sensor 20 detects that the oxygen concentration in the car meets the standard, the car circulation ventilation can also be achieved, that is, the external damper 10 is closed, the internal damper 19 is opened, and the circulating air in the car passes through the filter 182 from the internal damper 19 and passes through multiple one-way fans 183 and the first one-way valve 184. The circulating air in the car forms a stable laminar flow in the air inlet channel 181 without turbulence, ensuring the continuity and stability of the air flow before oxygen supply, and then passes through the first fan 11 and enters the cylinder 12 from the inlet 121, and finally leaves the cylinder 12 from the outlet 122, and then passes through the first oxygen-enriched channel 2. Although the O2 concentration of the circulating air in the car is lower than 21%, However, paramagnetic O2 will still be attracted by the magnetic field and enter the first oxygen-rich channel 2 more, so as to achieve the purpose of recycling O2, and finally enter the car through the diversion device 25, thereby reducing the temperature and improving the oxygen concentration in the car, thereby improving the riding comfort; the oxygen concentration in the car and the oxygen concentration in the internal damper 19 are respectively detected by the oxygen concentration sensor 20 in the car and the oxygen concentration sensor 20 at the internal damper 19, and the feedback is given to the controller 21, and the controller 21 adjusts the speed of the compressor 94, the speed of the first fan 11 and the electromagnet current (if an electromagnet is used) according to the feedback results, and determines the external circulation opening interval time and opening time according to the oxygen content measurement results, so as to ensure that oxygen deficiency and oxygen intoxication do not occur in the car.
