Obviously, the described embodiments are some, rather than all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts fall within the scope of protection of the present disclosure.

[0029] A portable in-vehicle oxygen generator is a healthcare device that can produce oxygen and meet the portable needs of users, mainly applied in various scenarios such as home, outdoors, and travel. The portable in-vehicle oxygen generator provides high-concentration oxygen to people in need of breathing assistance by separating oxygen from the air. The portable oxygen generator has the advantages of small size, light weight, and convenient operation, and is suitable for different groups of people such as the elderly, those with poor physical fitness, and pregnant women. The technical principle of the portable oxygen generator is mainly to separate oxygen from the air at high speed through a compressor to provide high-concentration oxygen. Compared with traditional oxygen supply devices such as oxygen cylinders or oxygen pipelines, the portable oxygen generator has higher portability and stability. It is suitable for short-term outdoor oxygen use, such as when the elderly go for a walk or young people travel to the plateau. Most portable oxygen generators adopt PSA (Pressure Swing Adsorption) and VPSA (Vacuum Pressure Swing Adsorption) technologies, which enable the oxygen generator to supply oxygen according to the user's breathing frequency to ensure efficient and safe oxygen supply. However, due to its working principle and characteristics, the portable oxygen generator in related technologies generally has the problem of high noise, which will have a great impact on the comfort of users during use, and currently, the above noise sources cannot be fundamentally solved.

[0030] In view of this, the embodiments of the present disclosure provide an in-vehicle oxygen generator that can reduce the impact of the noise generated by the in-vehicle oxygen generator on users. Figure 1 The following is a schematic structural diagram of the in-vehicle oxygen generator provided by the embodiments of the present disclosure. As Figure 1 shown, the in-vehicle oxygen generator includes a first housing 1, a second housing 2, a compressor 3, a molecular sieve 4, and a connection mechanism 5. The compressor 3 is disposed in the first housing 1, and the molecular sieve 4 is disposed in the second housing 2; the air inlet of the molecular sieve 4 and the air outlet of the compressor 3 are communicated through the connection mechanism 5. The second housing 2 is used to be disposed in the passenger compartment of the vehicle, and the first housing 1 is used to be disposed outside the passenger compartment of the vehicle.

[0031] In the in-vehicle oxygen generator provided by the present disclosure, the compressor 3 that generates relatively large noise during operation is disposed in the first housing 1, and the molecular sieve 4 that generates relatively small noise during operation is disposed in the second housing 2. The first housing 4 and the second housing 2 are communicated through the connection mechanism 5. When arranging the in-vehicle oxygen generator in the vehicle, the first housing 1 can be placed outside the passenger compartment of the vehicle, such as in the trunk of the vehicle, and only the second housing 2 is placed in the passenger compartment of the vehicle, reducing the noise conducted from the first housing 1 to the passenger compartment of the vehicle, which is beneficial to improving the user experience.

[0032] To make the technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0033] AsFigure 1 As shown in the figure, the on-vehicle oxygen generator provided by the embodiments of the present disclosure includes a first housing 1, a second housing 2, a compressor 3, a molecular sieve 4, and a connecting mechanism 5. The compressor 3 is disposed inside the first housing 1, the molecular sieve 4 is disposed inside the second housing 2, and the first housing 1 and the second housing 2 are separately arranged. The compressor 3 is used to inhale the air in the environment and compress the air through a piston to increase the pressure and density of the air, thereby providing power for subsequent oxygen separation. The molecular sieve 4 is used to adsorb nitrogen in the compressed air through a molecular material and collect and provide high-purity oxygen. The compressor 3 generates a relatively large noise during operation, and the molecular sieve 4 generates a relatively small noise during operation. Since the first housing 1 and the second housing 2 are separately arranged, the first housing 1 can be arranged in the trunk of the vehicle, and the second housing 2 can be arranged in the passenger compartment of the vehicle. The overall volume of the second housing 2 is small and does not occupy too much space in the passenger compartment. Moreover, the noise generated by the compressor 3 in the first housing 1 transmitted to the passenger compartment is small, which is beneficial to improving the user experience.

[0034] Figure 2 is an exploded view of the on-vehicle oxygen generator provided by the embodiments of the present disclosure. Refer to Figure 2 , the above-mentioned connecting mechanism 5 can be a bent pipe, and both ends of the bent pipe are respectively communicated with the compressor 3 in the first housing 1 and the molecular sieve 4 in the second housing 2, so as to convey the high-density air in the compressor 3 to the molecular sieve 4. Specifically, through holes can be respectively provided on the first housing 1 and the second housing 2, and both ends of the connecting mechanism 5 respectively pass through the through holes and enter the interiors of the first housing 1 and the second housing 2, and are communicated with the air outlet of the compressor 3 and the air inlet of the molecular sieve 4.

[0035] Exemplarily, two molecular sieves 4 are provided in the second housing 2. After one of the molecular sieves 4 is saturated with adsorption, the adsorbed nitrogen can be released by means of decompression to regenerate the molecular sieve 4, so as to perform the next adsorption. At this time, the other molecular sieve 4 performs adsorption, and the two molecular sieves 4 can alternately perform adsorption and regeneration, thereby ensuring that the on-vehicle oxygen generator can work continuously.

[0036] In some embodiments of the present disclosure, as Figure 2 shown, the on-vehicle oxygen generator further includes a first connecting pipe 7. An oxygen outlet 201 is provided on one surface of the second housing 2, and the oxygen outlet 201 is communicated with the air outlet of the molecular sieve 4 through the first connecting pipe 7. Exemplarily, two oxygen outlets 201 are provided on the front end surface of the second housing 2, and the oxygen outlets 201 are used for connecting with an external pipeline. When in use, the user only needs to connect the nasal oxygen tube or the oxygen mask to the oxygen outlet 201 on the second housing 2 to inhale the purified oxygen.

[0037] In some embodiments of the present disclosure, refer to Figure 2, the on-vehicle oxygen generator further includes a solenoid valve 6 and a second connecting pipe 8. The solenoid valve 6 is located in the first housing 1, and the air inlet of the solenoid valve 6 is communicated with the air outlet of the compressor 3 through the second connecting pipe 8. The high-pressure gas discharged by the compressor 3 enters the molecular sieve 4 after passing through the solenoid valve 6. The solenoid valve 6 is used to switch the flow direction of the compressed air, so that the compressed air flows into one of the two molecular sieves 4 for adsorption, and the other molecular sieve 4 that does not flow into the compressed air is regenerated. The solenoid valve 6 can also adjust the gas flow rate entering the molecular sieve 4, and close the valve when the gas pressure is too high due to a failure of the compressor 3 to prevent damage to the molecular sieve 4. The solenoid valve 6 is also arranged in the first housing 1, which can reduce the influence of the noise generated by the solenoid valve 6 on the user and improve the user experience.

[0038] Optionally, the connecting mechanism 5, the first connecting pipe 7 and / or the second connecting pipe 8 involved in the embodiments of the present disclosure are flexible hoses. The flexible hoses can facilitate the arrangement of the internal components of the first housing 1 and the second housing 2, and reduce the limitation on the relative positions between the first housing 1 and the second housing 2, so as to be easily arranged inside the vehicle.

[0039] In some embodiments of the present disclosure, as Figure 2 shown, the on-vehicle oxygen generator further includes two adapters, the two adapters are respectively communicated with the air outlets of the two molecular sieves 4, and the two adapters are respectively communicated with the first connecting pipe 7, and the first connecting pipe 7 is communicated with the oxygen outlet 201, so as to discharge the oxygen generated by the molecular sieve 4.

[0040] In some embodiments of the present disclosure, as Figure 2 shown, the on-vehicle oxygen generator further includes a silencer cover 9. The silencer cover 9 is located in the first housing 1, and the compressor 3 is located inside the silencer cover 9. In some embodiments, the solenoid valve 6 is located outside the silencer cover 9. The outer shell of the silencer cover 9 can be made of plastic or metal, and the inner wall of the silencer cover 9 is provided with sound-absorbing materials, such as foam, glass wool, etc., so as to improve the sound insulation effect on the compressor 3.

[0041] Optionally, referring to Figure 2 , a through hole 901 is provided on the silencer cover 9, and the on-vehicle oxygen generator further includes a third connecting pipe 12. One end of the third connecting pipe 12 is communicated with the compressor 3, and the other end passes through the through hole 901 and is thus communicated with the second connecting pipe 8 outside the silencer cover 9.

[0042] Figure 3 is a schematic diagram of the on-vehicle oxygen generator provided by the embodiments of the present disclosure. In some embodiments of the present disclosure, as Figure 3As shown, the connecting mechanism 5 includes a first joint 101 and a second joint 202. The first joint 101 is located on the first surface of the first housing 1, and the second joint 202 is located on the second surface of the second housing 2. The first surface is opposite to the second surface, and the second joint 202 is detachably communicated with the first joint 101. The second joint 202 is a cylindrical structure protruding from the second surface, and the first joint 101 is a groove structure recessed in the first surface. The second joint 202 can be inserted into the first joint 101 to form a sealed fit. When it is necessary to carry or arrange the entire on-vehicle oxygen generator, the first housing 1 and the second housing 2 can be communicated through the second joint 202 and the first joint 101. At this time, the first surface abuts against the second surface, and the gas generated by the compressor 3 in the first housing 1 can directly enter the molecular sieve 4 in the second housing 2 through the second joint 202 and the first joint 101. There is no need to connect the first housing 1 and the second housing 2 through pipelines, saving the overall layout space of the on-vehicle oxygen generator.

[0043] Exemplarily, four second joints 202 are provided on the second surface of the second housing 2, and four first joints 101 are provided on the first surface of the first housing 1. Each second joint 202 is hermetically connected to the first joint 101.

[0044] In some embodiments of the present disclosure, as Figure 3 shown, a connecting groove 103 is provided on the first surface of the first housing 1, and a buckle 203 is provided on the second surface of the second housing 2. The buckle 203 is snap-connected to the connecting groove 103. Exemplarily, two connecting grooves 103 are provided on the first surface of the first housing 1, and two buckles 203 are provided on the second surface of the second housing 2. The first surface of the first housing 1 is opposite to the second surface of the second housing 2, and the two connecting grooves 103 and the two buckles 203 are respectively snap-connected to fixedly connect the first surface of the first housing 1 and the second surface of the second housing 2 for easy carrying of the on-vehicle oxygen generator. The snap connection between the buckle 203 and the connecting groove 103 can also ensure the sealing performance of the connection between the second joint 202 and the first joint 101.

[0045] Optionally, referring to Figure 3 , an air inlet hole 102 is provided at the rear end surface of the first housing 1. The air inlet hole 102 is a plurality of through holes arranged in an array, and the air inlet hole 102 is communicated with the air inlet hole of the compressor 3 to supply air to the compressor 3.

[0046] Figure 4 is a perspective view of the on-vehicle oxygen generator provided by the embodiment of the present disclosure. In some embodiments of the present disclosure, as Figure 4As shown, the on-vehicle oxygen generator further includes a sensor 10. The sensor 10 is disposed in the first housing 1 and is configured to monitor the operating states of the compressor 3 and / or the solenoid valve 6. Exemplarily, the sensor 10 includes a pressure sensor, a flow sensor, a temperature sensor, and a vibration sensor. The pressure sensor is used to monitor the pressure of the compressed air of the compressor 3, the flow sensor is used to monitor the gas flow rate flowing out of the compressor 3, the temperature sensor is used to monitor the temperature when the compressor 3 is operating, and the vibration sensor is used to monitor the vibration condition of the compressor 3.

[0047] In some embodiments of the present disclosure, referring to Figure 4 , the connecting mechanism 5 further includes a connecting hose 501. The second joint 202 and the first joint 101 are respectively detachably connected to both ends of the connecting hose 501. The second joint 202 is communicated with the air inlet of the molecular sieve 4, and the first joint 101 is communicated with the air outlet of the compressor 3. Alternatively, the diameter of the connecting hose 501 is smaller than the diameters of the first joint 101 and the second joint 202. Both ends of the connecting hose 501 respectively pass through the second joint 202 and the first joint 101, so as to be communicated with the molecular sieve inside the second housing 2 and the compressor 3 inside the first housing 1. When it is necessary to assemble the first housing 1 and the second housing 2 together, it can be selected to first detach the connecting hose 501, then connect the second joint 202 with the first joint 101, and cooperate and connect the connecting groove 103 with the buckle 203. Alternatively, first stuff the redundant connecting hose 501 into the inside of the first housing 1 or the second housing 2, then connect the second joint 202 with the first joint 101, and cooperate and connect the connecting groove 103 with the buckle 203.

[0048] Optionally, as Figure 3-4 shown, exhaust holes 104 are provided on opposite sides of the first housing 1. The exhaust holes 104 are opposite to the exhaust ports of the solenoid valve 6 and are used to discharge the released nitrogen.

[0049] In summary, the embodiments of the present disclosure provide three ways of arranging the connecting mechanism 5. The first one is that the connecting mechanism 5 is a bent pipe, and the first housing 1 and the second housing 2 are only connected through the connecting mechanism 5. The second joint 101 is not provided on the first housing 1, and the first joint 202 is not provided on the second housing 2. The second one is that the connecting mechanism 5 includes a second joint 101 and a first joint 202, and the first housing 1 and the second housing 2 are only connected through the second joint 101 and the first joint 202. The second joint 101 and the first joint 202 are directly connected, and no other connecting components are provided between the second joint 101 and the first joint 202. The third one is that the connecting mechanism 5 includes a second joint 101, a first joint 202 and a connecting hose 501. The two ends of the connecting hose 501 are hermetically connected to the second joint 101 and the first joint 202 respectively, or the two ends of the connecting hose 501 pass through the second joint 101 and the first joint 202 respectively and are connected to the compressor 3 and the molecular sieve 4.

The compressor 3 is arranged in the first housing 1, the molecular sieve 4 is arranged in the second housing 2, and the first housing 1 and the second housing 2 are separated. The compressor 3 is used to inhale the air in the environment and compress the air through a piston to increase the pressure and density of the air, providing power for the subsequent oxygen separation process. The molecular sieve 4 is used to adsorb nitrogen in the compressed air through a molecular material and collect and provide high-purity oxygen. The compressor 3 generates a relatively large noise during operation, and the molecular sieve 4 generates a relatively small noise during operation. Since the first housing 1 and the second housing 2 are separated, the first housing 1 can be arranged in the trunk of the vehicle, and the second housing 2 can be arranged in the passenger compartment of the vehicle. The overall volume of the second housing 2 is small and will not occupy too much space in the passenger compartment. Moreover, the noise generated by the compressor 3 in the first housing 1 transmitted to the passenger compartment is small, which is beneficial to improving the user experience.
