Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted oxygen enrichment devices, and in particular relates to a plateau vehicle-mounted pressurized oxygen enrichment device. Background Art

[0002] Altitude sickness is a physiological stress response of the human body to the lack of oxygen in high altitude areas. It can be roughly divided into two types: acute and chronic. This reaction is mainly because in high altitude areas, the oxygen partial pressure in the atmosphere is reduced, which directly affects the oxygenation of the blood, resulting in insufficient oxygen supply to the human body, leading to hypoxia. Usually, the incidence of altitude sickness is related to factors such as altitude, temperature, humidity, air pressure, radiation, and mode of transportation. In addition, men, overweight people, patients with some diseases, and certain psychological states will also increase the risk of altitude sickness. In order to reduce the risk of hypoxia when people encounter insufficient oxygen supply, some existing vehicles will be equipped with oxygen supply equipment, so that the people in the car and the vehicle will reach corresponding relief, reducing the occurrence of altitude sickness. At present, vehicle-mounted oxygen supply equipment is used more and more widely, but there are still some oxygen supply equipment that have certain deficiencies in specific use, so they need to be improved.

[0003] Chinese patent publication number CN207158785U describes a device comprising, from bottom to top, an air storage chamber, an oxygen enrichment chamber, and an exhaust chamber. The air storage chamber has an air inlet on its sidewall. The oxygen enrichment chamber includes an inner chamber, a first vent on a first baffle located within the inner chamber, a first nitrogen outlet on the top of the inner chamber, and a second nitrogen outlet on the sidewall of the oxygen enrichment chamber, both connected via a nitrogen discharge pipe. An air baffle is suspended above the first vent within the inner chamber, and an oxygen permeable window is provided on the inner chamber sidewall below the air baffle, with an oxygen-enriched membrane on the window. Two second through-holes are provided on the second baffle, and a vacuum pump is installed in the exhaust chamber, connected to the second through-holes via two oxygen supply pipes. The vacuum pump is connected to a first oxygen outlet branch and a second oxygen outlet branch. This vehicle-mounted oxygen enrichment device can extract nitrogen during the oxygen enrichment process, improving the efficiency and purity of oxygen production.

[0004] However, although the above technical solution can achieve the purpose of supplying oxygen to the passenger compartment and the engine air intake in the vehicle when in use, the oxygen-enriched membrane is set in a block shape on the ventilation window during specific use, and the rest of the position will be blocked by the ventilation window, which will result in a small amount of oxygen passing through the oxygen-enriched membrane at one time, making it difficult for passengers in the vehicle to get oxygen in a short time. Especially when the vehicle travels to a plateau area and the altitude sickness becomes more and more severe, some people will feel unwell because they find it difficult to get oxygen in time, so it needs to be improved.

[0030] Example 2:

[0031] See also Figure 1 、 Figure 2 and Figure 4 As shown, a closed door is hingedly connected to one side of the air intake chamber 2. A collection box 10 is connected to the inner bottom wall of the air intake chamber 2. Two first positioning blocks 11 are fixedly connected to one side of the inner bottom wall of the collection box 10. First positioning blocks 11 have first connecting slots defined within them, and a connecting plate 12 is connected within the first connecting slots. A filter screen 13 is disposed within the connecting plate 12. The arrangement of the collection box 10 secures the first positioning blocks 11 within it, while simultaneously collecting impurities that fall from the filter screen 13. The opening of the first connecting slots allows the connecting plate 12 to slide into it. The arrangement of the filter screen 13 filters impurities contained in the gas entering the air intake chamber 2.

[0032] Two second positioning blocks are fixedly connected to one side of the top wall of the air intake chamber 2. A second connecting groove is defined within each of the second positioning blocks, and the top of the connecting plate 12 is aligned with the inner sidewall of the second connecting groove.

The mounting plate 25 and the fastening bolts secure the support chamber 1 to an appropriate position within the vehicle. The observation window allows personnel to observe the interior of the air passage chamber 3 in a timely manner.

[0033] The working principle of the utility model is as follows: the staff installs the entire device in the appropriate position in the car in advance through the mounting plate 25 and the fastening bolts, and at the same time, the two air intake pipes 24 pass through the car and are connected to the outside. When the car travels to the plateau area, the altitude sickness becomes more and more severe. At this time, the driver and passengers in the car can control the first vacuum pump 14 and the second vacuum pump 18 to start. The first suction pipe 15 at the air inlet end of the first vacuum pump 14 draws air through the air inlet cylinder 16 inside the air inlet chamber 2. At this time, the suction force is transmitted to the air inlet pipe 24, so that it absorbs gas from the outside. After the gas enters the air inlet chamber 2, it passes through the filter mesh 13 inside the two connecting plates 12 in advance, so that the impurities contained in the gas are filtered, and then it is transported to the first air delivery pipe 17 at the air outlet end of the first vacuum pump 14, and then it is transported to the inside of the support tube 4 through the first air delivery pipe 17. After entering the inside of the support tube 4, the gas is blocked by the blocking plate 6 in advance, so that the gas stays in the support tube 4 for a longer time. After entering the inside of the support tube 4, the gas is discharged to the outside through the air outlet 7. After passing through the air outlet 7, the gas is pre-mixed with oxygen-enriched gas. The membrane 8 contacts, allowing oxygen to pass through the oxygen-enriched membrane 8, and the remaining gas is discharged through the exhaust pipe 26. The oxygen passing through the inside of the support tube 4 is absorbed by the second suction pipe 19 at the air inlet end of the second vacuum pump 18, so that it is transported to the inside of the second air supply pipe 21 at the air outlet end of the second vacuum pump 18, and then transported to the inside of the air distribution pipe 22 through the second air distribution pipe 21, and finally enters the inside of the two air supply pipes 23 through the air distribution pipe 22, so that the passengers in the car and the engine air intake can all be supplied with oxygen. After the filter 13 has been used for a certain period of time, the staff will open the closed door and then pull the collection box 10 to the outside. At this time, the two first positioning blocks 11 and the connecting plate 12 are separated from the air inlet chamber 2, and then the staff will pull out the connecting plate 12 from the first connecting groove inside the two first positioning blocks 11. Finally, the staff will clean the filter 13 for subsequent use. After cleaning, the staff will insert the connecting plate 12 into the inside of the first connecting groove, and then slide it into the inside of the air inlet chamber 2 so that the top of the connecting plate 12 slides into the inside of the second connecting groove.
