[0002] The temperature difference between day and night is large in plateau areas. For people who work in plateau areas for a long time, especially those who come from plains to plateau areas, it is difficult to adapt to the hypoxic environment and they will have altitude sickness to a certain extent. Long-term hypoxic environment will directly lead to the decline of human function, which is extremely detrimental to the health of people who need to maintain high-altitude training or high-intensity exercise for a long time. At this time, oxygen concentrators are needed.

[0029] Please refer to Figure 1-Figure 6 The present invention provides a vehicle-mounted portable oxygen concentrator, comprising an oxygen concentrator body 1 and a power supply box assembly 2. The oxygen concentrator body 1 is provided with a first connecting portion 11 and a universal power supply port 12 for connecting an external power supply. The power supply box assembly 2 is provided with a second connecting portion 21. A battery pack 22 and a power supply boss 23 are arranged in the power supply box assembly 2. The battery pack 22 is composed of a plurality of batteries. The power supply boss 23 is electrically connected to the battery pack 23. After the first connecting portion 11 and the second connecting portion 21 form a detachable connection, the oxygen concentrator body 1 and the power supply box assembly 2 are combined into an integral structure, and the universal power supply port 12 is electrically connected to the power supply boss 23. When the oxygen concentrator body 1 and the power supply box assembly 2 are separated, the oxygen concentrator body 1 can be connected to an external power supply through the universal power supply port 12 for power supply. The external power supply can be a vehicle-mounted power supply or a mains power supply. The universal power supply port 12 can be set as a vehicle-mounted power supply socket or a mains power supply socket according to the model or style of the oxygen concentrator body 1, or a socket that can be shared by the vehicle-mounted power supply and the mains power supply.

[0030] In this embodiment, after the power supply box assembly 2 is provided with a battery pack 22, it becomes a portable power supply or backup power supply. When the power of the battery pack 22 is needed, the oxygen concentrator body 1 and the power supply box assembly 2 are combined into an integral structure by forming a detachable connection through the first connecting portion 11 and the second connecting portion 21, and the power supply boss 23 supplies power to the universal power supply port 12, which is convenient for carrying. When the power of the power supply box assembly 2 is exhausted, the oxygen concentrator body 1 and the power supply box assembly 2 can be separated, and the oxygen concentrator body 1 can be taken out separately after separation. At this time, the oxygen concentrator body 1 is lighter without the connection of the power supply box assembly 2, and the oxygen concentrator body 1 can be connected to an external power supply through the universal power supply port 12 for power supply. When going out, it can be connected to a vehicle power supply or a mains power supply, so that the oxygen concentrator body 1 can be used normally, realizing seamless switching in different application scenarios;

When the insertion boss 111 is fully inserted in the insertion groove 211, the universal power supply port 12 is electrically connected to the power supply boss 23. Since the insertion groove 211 limits the insertion position and space of the insertion boss 111, the stability and convenience of the electrical connection between the universal power supply port 12 and the power supply boss 23 are improved. The electrical connection between the universal power supply port 12 and the power supply boss 23 can be mutual plug-in, it can also be the abutment of electrical contacts, or it can be a wireless power supply connection.

Inside the bottom, a light-weight circuit board 14, a molecular sieve tower 16, a solenoid valve group 17, and an oxygen concentration sensor 18 are installed inside the top of the housing assembly 13, so that the center of gravity of the oxygen generator body 1 can be lowered, thereby improving the stability of the oxygen generator body 1 connected to the power supply box assembly 2; the molecular sieve tower 16 is divided into a tower A and a tower B, and the solenoid valve group 17 is provided with two solenoid valves, and the tower A and the tower B are respectively connected and conducted to the two solenoid valves.

To provide the oxygen supply interface 19 with sieved oxygen, after the solenoid valve connected to Tower A is opened, Tower A provides the sieved oxygen to the oxygen supply interface 19. At this time, oxygen flows from the solenoid valve to the oxygen concentration sensor 18, and then flows to the oxygen supply interface 19. After the oxygen supply of Tower A is completed, the solenoid valve connected to Tower A is closed, and at the same time, the solenoid valve connected to Tower B is opened, and Tower B provides the oxygen supply interface 19 with sieved oxygen. At this time, oxygen flows from the solenoid valve to the oxygen concentration sensor 18, and then flows to the oxygen supply interface 19. After the oxygen supply of Tower B is completed, it is Tower A's turn to supply, and they are used alternately in turn, that is, Tower A and Tower B supply oxygen in turn to maintain a continuous supply of oxygen.
