Description

Technical Field

[0001] The present invention belongs to the technical field of oxygen production equipment, and in particular relates to a control device and a control method for a portable oxygen production-disinfection integrated machine. Background Art

[0002] The patent number is: CN104154598A. The Negative Ion Air Purifier mentions: Using a turbofan to multiply the air to generate strong winds blowing towards the negative ion generator head and the ozone generator head, respectively, a large number of negative ions are generated to purify the air, and it can remove the ozone produced by the incidental generation, and generate a large amount of ozone for disinfection. In addition, it can also atomize humidified air and produce oxygen, and can also be used as a bladeless fan. This patent focuses on the combination of structural optimization and functional superposition to achieve the purpose of one machine with multiple uses, and does not provide a novel control method.

[0003] The patent number is: CN116839148A. The "A Sleeping Air Disinfection and Purification Laminar Flow Device" mentions: The plasma generation structure can add negative ions to the indoor ambient air. When the indoor environment lacks oxygen, the oxygen generation structure can be activated to automatically release the oxygen needed by the human body into the room. There is no detailed control logic and control method for the two function switching of ion generation and oxygen release.

[0004] The patent number is: CN201473312U. "Household Intelligent Oxygen Generator Using Polymer Membrane Separation" mentions: The intelligent oxygen generator using polymer membrane separation includes an air input fan, a polymer oxygen-generating membrane component, an oxygen-enriched collection box, a vacuum pump, an oxygen-enriched flow regulating valve, and a water vapor separation box connected in sequence, and the input end of the intelligent single-chip control board of the automatic control system is connected to the control panel. However, the cost of the oxygen-generating membrane component is high, the oxygen concentration is very low (28%-32%), and there are too many components, which is not conducive to stable oxygen output and mass production.

[0005] Through the above analysis, the problems and defects of the existing technology are: the existing conventional means cannot provide efficient control logic and control methods for combining oxygen production and disinfection, and most of the function implementation methods are relatively rough, that is, a simple combination of multiple separate functions is adopted. Therefore, it is extremely important to establish a set of efficient control methods for oxygen production and disinfection. Summary of the invention

[0006] In view of the problems existing in the prior art, the present invention provides a control device and a control method for a portable oxygen generator-disinfection integrated machine.

[0007] The present invention is implemented as follows: a control device for a portable oxygen generator-disinfection integrated machine, characterized in that the device comprises: an oxygen generator module, a negative ion generator module;

[0008] The oxygen production module includes a speed regulator, an oil-free compressor, a cooling fan, a control valve, a molecular sieve tower,

[0009] Oxygen storage tank, pressure equalizing valve;

[0010] The oxygen production module, the components are connected in sequence according to the flow direction of the gas path;

[0011] The negative ion generating module comprises a negative ion generator, which is the same as the oxygen storage tank.

[0012] Another object of the present invention is to provide a control method for a portable oxygen generator-disinfection integrated machine, the method comprising:

[0013] S1: The machine is turned on and reads the local mode. If breathing is detected, it is adjusted to pulse mode, otherwise it is fixed frequency mode;

[0014] S2: After being configured in fixed frequency mode, it enters the air purification module and is connected to the negative ion generator;

[0015] S3: Further, if the oxygen supply mode button is pressed in this mode, it will return to the local reading mode, otherwise it will continue to execute the fixed frequency mode;

[0016] S4: Further, the fixed frequency mode discharges oxygen once every 3 seconds;

[0017] S5: After being configured as pulse mode, if the oxygen supply mode button is pressed to adjust the oxygen supply mode, it will return to the local reading mode, otherwise proceed to the next process;

[0018] S6: Further, in this mode, if breathing is detected, oxygen will continue to be supplied according to the breathing rate;

[0019] S7: Further, in this mode, if no breathing is detected within 30 seconds, the system will return to S5;

[0020] S8: Further, in this mode, if the pressure sensor detects that the tank pressure exceeds 130kpa, it will automatically switch to the fixed frequency mode, in which the negative ion generator is connected;

[0021] S9: Further, in this mode, if the pressure sensor detects that the tank pressure does not exceed 130 kPa, it will return to S5;

[0022] S10: Further, continuing S9, if breathing is detected, switching to pulse mode, oxygen will continue to be supplied according to the breathing frequency, and the subsequent process will return to S5 to continue execution;

[0023] S11: Further, continuing S9, if no breathing is detected, the fixed frequency mode will release oxygen once every 3 seconds;

[0024] S12: Further, continuing S11, if the oxygen supply mode button is pressed to adjust the oxygen supply mode, the subsequent process will return to S1 to continue execution, otherwise it will return to S10 to continue execution.

[0025] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows:

[0026] First, the present invention combines the functions of the oxygen supply module and the air purification module to achieve the purpose of supplying oxygen to the human body in the pulse mode of the oxygen generator and purifying the air in the fixed frequency mode.

[0027] The present invention provides a control method and control flow for freely switching between fixed frequency and pulse dual modes. On the one hand, it is convenient for oxygen inhalers with different breathing frequencies to absorb oxygen and achieve the effect of efficient oxygen absorption. On the other hand, when oxygen is not inhaled, fixed frequency oxygen supply can increase overvoltage protection, and combined with an air purification module, it can also add negative ions to the air to purify the air.

[0028] In addition, during the S9 process, the oxygen production system is under high-pressure surplus conditions, and the pressure sensor is used to feed back to the compressor speed governor to adjust the gas volume of the compressor and discharge high-pressure gas so that the compressor exhaust volume adapts to the actual gas consumption, while ensuring the pressure stability and efficient operation of the oxygen production system.

[0029] Components such as nasal oxygen tubes that are used for a long time may harbor bacteria. While the air purification module purifies the air in fixed-frequency mode, it can also help remove bacteria from the nasal oxygen tube components.

[0030] Second, in the prior art, portable oxygen generators and air disinfection equipment are usually separated, which means that users need to carry and operate multiple devices during use, which is inconvenient to move and use. In addition, traditional oxygen generators have problems of low efficiency and high energy consumption in the oxygen separation process, and cannot meet the needs of efficient oxygen production. Existing air disinfection equipment mainly relies on chemical agents, which poses secondary pollution and safety hazards. Finally, the prior art has little research on the generation of negative ions and oxygen combination, and fails to fully utilize the air purification and disinfection effects of negative ions.

[0031] The present invention solves the problem that users need to carry multiple devices by integrating the oxygen production module and the negative ion generating module into a portable device, thereby improving the convenience and mobility of use. At the same time, the present invention improves the oxygen production efficiency and reduces energy consumption by optimizing the design of the oxygen production module and adopting components such as an oil-free compressor, a molecular sieve tower and a pressure equalizing valve. In addition, by combining the negative ion generator with the oxygen production module, the synchronous generation of negative ions and oxygen is achieved, thereby enhancing the air purification and disinfection effects. Finally, the design of the present invention ensures the safety and stability of the equipment, and avoids the secondary pollution and safety hazards of traditional air disinfection methods.

[0032] Through the present invention, the portable oxygen generator-disinfection integrated machine has made significant technical progress. First, the integrated design makes the equipment more portable, suitable for outdoor activities and mobile use, and solves the problem of users carrying multiple devices. Secondly, the optimized oxygen production module design improves the efficiency and purity of oxygen separation, reduces the energy consumption of the equipment, and extends the service life of the equipment. In addition, the design of combining negative ions with oxygen significantly improves the effect of air purification and disinfection, and provides a higher quality breathing environment. Finally, the present invention also has significant improvements in safety and stability, and through a variety of protection mechanisms, it ensures the reliable operation of the equipment in various usage environments.

[0033] In summary, the present invention solves multiple technical problems existing in the prior art by integrating oxygen production and disinfection functions into a portable device, significantly improving the portability, oxygen production efficiency, air purification effect and safety of use of the device. This technological advancement not only improves the user experience, but also provides a new direction and idea for the development of portable oxygen production and air disinfection equipment. Through the present invention, users can obtain efficient, convenient and safe oxygen and air disinfection services in more scenarios, significantly improving their quality of life and health level.

[0099] 3) Air flow control:

[0100] The compressed air passes through the control valve and enters the molecular sieve tower.

[0101] The control valve ensures that the gas flow follows the predetermined path and enters the molecular sieve tower for separation.

[0102] 4) Oxygen separation:

[0103] The molecular sieve tower separates oxygen from compressed air through physical adsorption and separation technology.

[0118] At the same time, the negative ion generator generates negative ions and combines with the oxygen in the oxygen storage tank to provide negative ion oxygen.

[0119] Through the coordinated work of various components, the integrated functions of portable oxygen production and air disinfection are realized.

[0120] 4. Control and Regulation:
