[0031] In order to make the technical scheme and technical effect of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.

[0032] The utility model aims to provide a vehicle-mounted oxygen generator, which uses the air stored in the air tank of the vehicle's air brake system as the input gas source, adopts molecular sieve pressure swing adsorption oxygen production technology to produce oxygen, and has a vehicle-mounted oxygen generator with five oxygen supply outputs, which effectively solves the oxygen inhalation needs of vehicle passengers in plateau areas during driving, can meet the oxygen inhalation of 5 people at the same time, and realizes on-the-go use and continuous oxygen supply.

[0033] The vehicle-mounted oxygen generator includes a device body 100 , and the device body 100 is provided with an operation panel 110 and a pipeline system 120 .

[0034] The operation panel 110 is exposed on the surface of the device body 100. Figure 1The operation panel 110 has an air inlet 111, a nitrogen outlet 112, an oxygen outlet 113, a power input socket 114, a switch 115 and a flow meter 116. Specifically, the air inlet 111 introduces the air stored in the air tank of the vehicle's air brake system into the pipeline system 120 through the air supply pipeline for use as an input air source. The advantage of this design is that the core components of the traditional molecular sieve oxygen generator, such as the compressor, radiator, fan, etc., are eliminated, thereby effectively reducing the volume, weight, noise and power of the whole machine and improving product reliability. The nitrogen outlet 112 leads the nitrogen separated by the integrated molecular sieve tower 125 out of the vehicle cabin through the exhaust pipeline. The oxygen outlet 113 is connected to an oxygen supply plug or an oxygen inhalation tube for diffuse oxygen supply in the vehicle cabin or nasal oxygen supply for passengers. The oxygen supply in the cabin is carried out by the oxygen generator and the separated nitrogen is discharged to ensure the increase of the oxygen content in the cabin and improve the oxygen inhalation environment of the passengers. Preferably, refer to Figure 3 The oxygen outlet 113 is designed as an integrated structure of one normally open oxygen outlet 1130 and four normally closed oxygen outlets 1131, and the normally open oxygen outlet 1130 is located at the axisymmetric center of the four normally closed oxygen outlets 1131, that is, the four normally closed oxygen outlets 1131 are symmetrically distributed around the normally open oxygen outlet 1130. The four normally closed oxygen outlets 1131 have no oxygen output when not in use. When it is needed, oxygen can be automatically output by inserting the oxygen inhalation plug. At this time, the flow meter can be adjusted to the output flow rate to meet the use demand according to the number of users; when the vehicle-mounted oxygen generator is working, oxygen can be automatically output from the normally open oxygen outlet 1130 and diffused into the vehicle cabin, and the vehicle passengers can also use the oxygen inhalation tube to connect the normally open oxygen outlet 1130 to directly inhale oxygen. The five-way oxygen supply output is designed to meet the simultaneous oxygen inhalation use of 5 vehicle passengers. Preferably, the normally open oxygen outlet 1130 is in the form of a pagoda joint. The power input socket 114 is connected to the input cable to connect the vehicle-mounted DC 12V power supply. In this way, the vehicle-mounted DC 12V is directly used as the power supply, making the product small in size and suitable for installation and use in a narrow space inside the vehicle. The switch 115 is used to turn on and off the vehicle-mounted oxygen generator. When the vehicle is powered on, turn on the switch 115, and the vehicle-mounted oxygen generator immediately starts working, continuously and uninterruptedly produces oxygen and outputs it from the oxygen outlet 113. The flow meter 116 is used to adjust the oxygen flow rate of the oxygen outlet 113. Adjusting the knob of the flow meter 116 can ensure that the oxygen flow rate of the oxygen outlet 113 meets the oxygen inhalation use of different people at the same time. The adjustment range of the oxygen flow rate is 0 to 10L / min, ensuring that when 5 people are inhaling oxygen at the same time, each passenger can inhale 2L / min of oxygen. In order to facilitate personnel to operate and observe the vehicle-mounted oxygen generator, the above-mentioned buttons, connectors, knobs, etc. are all designed on the same operation panel 110; the air inlet 111, nitrogen outlet 112, and oxygen outlet 113 are all designed as quick-plug connectors, which can be easily and quickly connected to the air pipe.

[0035] The pipeline system 120 is disposed inside the device body 100. Figure 2 The pipeline system 120 uses the air stored in the air tank of the vehicle's air brake system as the input gas source, and the input gas source is separated into nitrogen and oxygen by pressure swing adsorption through the pressure reducing valve 124 and the integrated molecular sieve tower 125. The pipeline system 120 includes an on-off valve 121, a filter assembly, a pressure reducing valve 124, an integrated molecular sieve tower 125, a pressure regulating valve 126, an integrated oxygen terminal 127 and a controller 128. Specifically, the filter assembly is connected to the on-off valve 121 and the pressure reducing valve 124 at both ends along the direction of the input gas source inflow; the pressure regulating valve 126 is connected to the integrated molecular sieve tower 125 through an air pipe. The power input socket 114 connects the vehicle-mounted DC 12V power supply to the controller 128, and the controller 128 is electrically connected to the on-off valve 121 and the integrated molecular sieve tower 125, respectively. The integrated oxygen terminal 127 realizes one-way oxygen input and five-way oxygen output, which can meet the needs of five people breathing oxygen at the same time. In addition, the integrated molecular sieve tower 125 is connected to the nitrogen outlet 112 through an air pipe to discharge the separated nitrogen. The filter assembly includes a primary filter 122 and a high-efficiency filter 123 in sequence along the direction of the input gas source inflow, which are used to remove impurities such as dust, moisture, and oil in the air to produce clean gas. The integrated oxygen terminal 127 is set on the inner wall of one side adjacent to the operation panel 110, and the integrated oxygen terminal 127 is connected to the oxygen outlet 113.

[0036] The oxygen generator body 100 is fixedly connected to the vehicle via a transition plate 200 .

[0037] When working, refer to Figure 4 The air stored in the air tank of the vehicle air brake system is used as the input air source, and the input air source pressure is 0.3~0.5MPa. When the vehicle occupants need to breathe oxygen, the switch 115 of the oxygen generator operation panel 110 is turned on, the controller 128 is powered on, and the on-off valve 121 and the integrated molecular sieve tower 125 are controlled to work. The on-off valve 121 is opened, and the input air source air enters from the air inlet 111 of the vehicle-mounted oxygen generator, and is processed by the primary filter 122 and the high-efficiency filter 123 in sequence to remove dust, moisture, oil and other impurities in the air to become clean gas. After passing through the pressure reducing valve 124, the air pressure is controlled between 0.2 and 0.3 MPa. The air reaching the set pressure is separated by the pressure swing adsorption of the molecular sieve in the integrated molecular sieve tower 125, and the nitrogen is transported to the nitrogen outlet 112 and discharged outside the vehicle. The oxygen flows out of the integrated molecular sieve tower 125, and is transported to the integrated oxygen terminal 127 through the pressure reducing and limiting flow of the pressure regulating valve 126 and the flow meter 116. The oxygen output from the oxygen outlet of the integrated oxygen terminal 127 can be directly provided for the personnel to breathe.

[0038] The utility model can be installed on large trucks, long-distance buses and vehicles traveling between plateaus and plains to solve the problem of oxygen inhalation for vehicle passengers in an oxygen-deficient environment. The vehicle-mounted oxygen generator provided by the utility model has the advantages of small size, light weight, low noise, low power, high reliability, ready to use, and real-time oxygen production and supply.
