[0003] Some oxygen generators on the market also have a nebulization function. The oxygen atomization process generally uses molecular sieve physical adsorption and desorption technology to purify the air to generate high-purity oxygen. Part of the oxygen is output through the oxygen outlet, and the other part is processed into high-pressure oxygen through the built-in nebulizer, and then sprayed into mist oxygen through the nozzle and enters the respiratory tract and lungs to achieve the purpose of local treatment (antispasmodic, anti-inflammatory, expectorant) and systemic treatment.

[0080] The gas output can be adjusted by setting the gear position through the gear button (not shown in the figure), so that the atomizer can select the flow rate. Different flow rates can be adjusted for different user groups. For example, the flow rate is adjusted to a small gear when used by children, and adjusted to a large gear when used by adults.

[0081] Furthermore, the control module 500 also includes a selection unit 550; the selection unit 550 is electrically connected to the MCU and is used to select different working modes.

[0082] Furthermore, the multifunctional portable oxygen concentrator further includes a selection button 610; the selection button 610 is disposed on the accommodating shell 600 and is structurally connected to the selection unit 550 for manually selecting a working mode.

[0086] When only the atomization function is used, Figure 3 , Figure 3 It is a schematic diagram of the atomization gas path of the multifunctional portable oxygen concentrator in the utility model; its implementation method is that when the machine is turned on, the oxygen valve 310, the breathing valve 330, the first flow valve 230, and the second flow valve 350 are all in a closed state, and air enters the air intake filter 110. The clean air after filtration passes through the DC oil-free compressor 120, and the high-pressure air comes out and enters the first three-way diverter 210, and then passes through the second three-way diverter 2203. When the first pressure sensor 510 of the control module 500 recognizes that the pipeline pressure is 0.1MPa, the first flow valve 230 is opened, and then enters the third three-way diverter 240, and then enters the one-way valve 250, and then passes through the throttle 260 (aperture 0.8mm), and then passes through the fourth three-way diverter 410 and the oxygen outlet 420 to reach the nebulizer cup 430 component, so that the medicine is atomized to achieve atomization treatment of respiratory diseases. During this working process, when the first pressure sensor 510 on the control module 500 circuit board senses that the pressure has reached 0.18MPa, it will feedback a signal to the circuit board to control the rotation speed of the DC oil-free compressor 120 so that the output pressure remains below 0.18MPa. In addition, the first flow valve 230 can set the gear to adjust the gas output, so that the atomization can select the flow rate. Different flow rates can be adjusted for different user groups. For example, when children use it, the flow rate is adjusted to a small gear, and when adults use it, it is adjusted to a large gear.

[0087] Further, the oxygen production component includes an oxygen production valve 310, a molecular sieve 320, a breathing valve 330, an oxygen tank 340, and a second flow valve 350; the air inlet of the oxygen production valve 310 is connected to the second connecting port of the first three-way diverter 210, and the air outlet is connected to the air inlet of the molecular sieve 320; the air outlet of the molecular sieve 320 is connected to the first connecting port of the breathing valve 330, and the second connecting port of the breathing valve 330 is connected to the first connecting port of the oxygen tank 340; the second connecting port of the oxygen tank 340 is connected to the second pressure sensor 520 for transmitting the gas circuit pressure; the third connecting port of the breathing valve 330 is connected to the third pressure sensor 530 for transmitting the gas circuit pressure; the second connecting port of the oxygen tank 340 is connected to the air inlet of the second flow valve 350, and the air outlet of the second flow valve 350 is connected to the second connecting port of the third three-way diverter 240.

[0088] Furthermore, the output component includes a fourth three-way diverter 410 and an atomizer cup 430; the first connecting port of the fourth three-way diverter 410 is connected to the throttle 260, the second connecting port is connected to the fourth connecting port of the breathing valve 330, and the third connecting port is connected to the atomizer cup 430 for output.

[0090] When choosing to do both oxygen therapy and atomization, such as Figure 4 , Figure 4It is a schematic diagram of the dual-function gas circuit of the multifunctional portable oxygen concentrator in the utility model; its implementation method is that when the machine is turned on, the first electronic flow valve and the second electronic flow valve are in a closed state, the electronic valve of the air outlet channel of the breathing valve 330 is also in a closed state, and the oxygen concentrator valve 310 is in an open state. Air enters the air inlet filter 110, and the clean air after filtration passes through the direct current oil-free compressor 120. The high-pressure air enters the first three-way diverter 210 through the first connecting port, passes through the second three-way diverter 220 through the third connecting port, enters the oxygen valve 310 through the second connecting port, and then enters the molecular sieve 320 component. The oxygen replaced by the molecular sieve 320 component enters the breathing valve 330 channel and is connected to the oxygen tank 340. The oxygen is stored in the oxygen tank 340. When the second pressure sensor 520 and the third pressure sensor 530 on the circuit board recognize that the pipeline pressure reaches 0.1 MPa, the second flow valve 350 and the first flow valve 230 are opened at the same time, and then enter the third three-way diverter 240, then enter the one-way valve 250, and then pass through the throttle 260 (aperture 0.8 mm), and then pass through the fourth three-way diverter 410 to exhaust and oxygen outlet 420 to reach the nebulizer cup 430 component, so that the medicine is atomized to achieve atomization treatment of respiratory diseases. During this working process, when the second pressure sensor 520 and the third pressure sensor 5302 on the circuit board sense that the pressure reaches 0.18MPa, they will feedback signals to the circuit board to control the speed of the DC oil-free compressor 120 so that the output pressure remains below 0.18MPa. In addition, the first flow valve 230 and the second flow valve 350 can synchronously coordinate the setting of the gear to adjust the gas output, so that the atomization can select different flow rates and adjust different oxygen concentrations. In this process, oxygen output is a continuous oxygen output process. Oxygen therapy and atomization are performed simultaneously, which is more conducive to the treatment of respiratory diseases in patients.

The user can also adjust the gas output through a button, thereby realizing precise control of the gas output of atomization or oxygen production.
