Description

Technical Field

[0001] The present invention relates to the technical field of oxygen concentrators, and in particular to an oxygen concentrator with an atomization function and a control method and device thereof. Background Art

[0002] Portable oxygen concentrators have a lot in common with general micro oxygen generators. They are mainly composed of compressors, adsorption towers, control valves, control microcontrollers, oxygen storage tanks, and various detection and alarm systems. One of the main design purposes of portable oxygen concentrators is to be easy to carry, so built-in batteries are added, and external batteries are attached to enable them to be used outdoors for a long time. The oxygen flow rate of portable oxygen concentrators is relatively small, and very advanced oxygen-saving technology is needed to support it. Oxygen-saving technology directly determines the hard indicators such as the volume, weight, and oxygen flow rate of portable oxygen concentrators. Oxygen concentrators and nebulizers have many overlapping usage scenarios. For example, COPD patients need to inhale oxygen for a long time and need nebulizer inhalation treatment. Patients often need to purchase oxygen concentrators and nebulizers. There are also some oxygen concentrators with nebulization function on the market, but the nebulized particles are often large, resulting in reduced treatment effect for users, and then continue to purchase special nebulizers, increasing treatment expenses. Most of the existing oxygen concentrators with nebulization function are connected to a medicine bottle at the end of the oxygen outlet pipe, and concentrated oxygen is used as a nebulization power to nebulize the drug solution in the medicine bottle. When the oxygen flow rate needs to be adjusted, the oxygen flow rate is reduced, the shear force generated by the oxygen flow on the drug solution becomes smaller, and the nebulization effect is reduced. Therefore, it is difficult to ensure the nebulization effect when concentrated oxygen is used as the nebulization power. In order to solve the above problems, the present invention proposes an oxygen concentrator with atomization function. Summary of the invention

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] The following is combined with Figure 1-4 The present invention is further described with examples: In this embodiment, Figure 1 As shown, an oxygen concentrator with atomization function comprises an air treatment system 1, a three-way valve 2, a nebulizer 3 and an air oxygen production system 4, wherein the three-way valve 2 is connected between the air treatment system 1, the nebulizer 3 and the air oxygen production system 4, wherein the air treatment system 1 inputs air to the three-way valve 2, the three-way valve 2 is used to distribute the ratio of air entering the nebulizer 3 and the air oxygen production system 4, and the humidified air sprayed by the nebulizer 3 is mixed with the oxygen generated by the air oxygen production system 4 and discharged; Specifically, the three-way valve 2 can adjust the ratio of air entering the atomizer 3 and the air oxygen production system 4, thereby being able to change the oxygen content of the mixed exhaust gas of the humidified air sprayed from the atomizer 3 and the oxygen produced by the air oxygen production system 4.

[0019] In this embodiment, the air treatment system 1 includes a multi-stage filter 11, a compressor 12, and a condenser 13 which are connected in sequence, and the output end of the condenser 13 is connected to the inlet of the three-way valve 2; Specifically, the multi-stage filter 11 filters the air, and the filtered air is sent to the compressor 12 for compression. The compression causes the air temperature to rise, and the compressed air is cooled through the condenser 13. The cooled compressed air is sent to the atomizer 3 and the molecular sieve 42 through the three-way valve.

[0020] In this embodiment, the air oxygen production system 4 includes a diverter valve 41, a molecular sieve 42, an oxygen storage tank 43, a pressure relief valve 44, a flow control valve 45 and a one-way valve 46 connected in sequence, one output end of the three-way valve 2 is connected to the atomizer 3, and the other output end of the three-way valve 2 is connected to the diverter valve 41. A flow sensor 47 is installed between the flow control valve 45 and the one-way valve 46. The flow sensor 47 is electrically connected to a PLC controller, and the PLC controller adjusts the operating power of the compressor 12 according to the data of the flow sensor 47; Specifically, the molecular sieve 42 has the functions of screening molecules, adsorption, ion exchange and catalysis. Non-oxygen molecules can be screened to produce pure oxygen. The pressure relief valve 44 plays a cut-off role, the flow control valve 45 plays a control role, and the one-way valve 46 can prevent gas backflow.

[0021] In this embodiment, at least two molecular sieves 42 are provided, the diverter valve 41 is connected to the input end of each molecular sieve 42, and the ends of the molecular sieves 42 are connected to the oxygen storage tank 43; Specifically, the diverter valve 41 is used to control the molecular sieve 42 to be intermittently connected to the three-way valve 2. When one molecular sieve 42 is connected to the three-way valve 2, the other molecular sieve 42 not connected to the three-way valve 2 is opened to release pressure. This cycle can allow the oxygen production process to continue.

[0022] Figure 2 The flowchart of the control method of an oxygen concentrator with atomization function provided by the present invention is applied to a blood oxygen detector terminal, which can display pictures, videos, text messages, WeChat and other information. The terminal can be equipped with any terminal device with a display screen, such as a mobile phone, a computer, a digital broadcast terminal, a message transceiver, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, etc. The control method of an oxygen concentrator with atomization function provided in this embodiment includes the following steps S1-S3: In step S1, the oxygen output flow rate is obtained, where the oxygen output flow rate is the flow data of the flow sensor in unit time; In step S2, the flow data required to be produced by the compressor in unit time is calculated according to the oxygen output flow rate as the input flow rate; In step S3, a corresponding input voltage is matched according to the relationship between the input flow rate and the compressor input voltage; In this implementation, the relationship between the input flow rate and the compressor input voltage needs to be experimentally determined in advance. Generally, the relationship between the input flow rate and the compressor input voltage is in direct proportion.

[0023] In this embodiment, the flow data required to be produced by the compressor in unit time is calculated according to the oxygen output flow rate, and the coefficient calculation formula used is as follows: v(total) = v(oxygen) / m + v(oxygen) / m / n Wherein, v(total) represents the input flow rate, v(oxygen) represents the oxygen output flow rate, m represents the loss ratio of the air oxygen generation system, and n represents the ratio of the gas flow rate entering the air oxygen generation system and the atomizer per unit time; In this implementation, v (oxygen) is the expected measured value of the flow sensor. When v (oxygen) reaches the expected measured value, the system is stable. When air passes through the air oxygen generation system, non-oxygen components will be absorbed by the molecular sieve, resulting in gas mass loss. In a certain altitude area, the loss ratio of the air oxygen generation system is a constant. The gas flow ratio entering the air oxygen generation system and the atomizer per unit time is affected by the opening of the three-way valve, which can adjust the oxygen content of the exhaust gas.

At the same time, atomization will consume part of the compressed air after the compressor. The flow data required to be generated by the compressor per unit time can be calculated based on the oxygen output flow rate, and the air power consumed by atomization can be automatically compensated, thereby appropriately increasing the compressor power, so that the atomization effect is not affected by the oxygen flow rate, saving treatment expenses for users.
