Therefore, the first objective of this invention is to provide a control method for an oxygen generator, which can determine the optimal oxygen generation angle based on multiple preset angles, enabling the oxygen-generating membrane assembly to generate oxygen at the optimal angle, thereby improving the oxygen generation effect and reliability of the oxygen generator and enhancing the user experience.

[0030] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0031] The control method, apparatus, air conditioning equipment, and medium of the oxygen generating device according to embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0032] Figure 1 This is a schematic flowchart of a control method for an oxygen generating device according to an embodiment of the present invention, as shown below. Figure 1 As shown, the control method of the oxygen generating device in this embodiment of the invention includes the following steps S11, S13, S15 and S17.
[0033] S11: After the oxygen generator starts producing oxygen, control the rotary motor to rotate sequentially at multiple preset angles.
[0034] S13: Whenever the rotary motor rotates to the desired position, the oxygen concentration in the oxygen outlet pipeline of the oxygen generator is acquired.
[0035] S15: Determine the optimal oxygen production angle based on the oxygen concentration corresponding to multiple preset angles.
[0036] S17: By controlling the rotary motor, the oxygen generating membrane assembly generates oxygen at the optimal oxygen generating angle.
[0037] In one example, such as Figure 2As shown, the oxygen generator 200 includes an oxygen generator motor M, an oxygen generator membrane assembly 202, a rotary motor 203, an oxygen concentration sensor 204, an oxygen enrichment tube 205, and a connecting pipe 206. The oxygen generator 200 also has an air inlet 207. The oxygen generator membrane assembly 202 is mounted on the rotary motor 203 and includes an oxygen generator membrane. The oxygen generator membrane can be a planar membrane. The rotary motor can be a stepper motor or an angle motor. The oxygen generator membrane can be a selective permeation membrane. The two ends of the connecting pipe 206 are connected to the permeation side Y of the oxygen generator membrane assembly 202 and the oxygen input end X of the oxygen generator motor M, respectively. The oxygen enrichment tube 205 is connected to the output end of the oxygen generator motor M. The oxygen generator motor M is located downstream of the gas path. The oxygen concentration sensor 204 is installed inside the oxygen enrichment tube 205.
[0038] The oxygen generation principle of the oxygen generator is roughly as follows: After the oxygen generator motor M is turned on, it drives the air near the permeate side Z of the oxygen generator membrane assembly 202 to flow towards the oxygen generator membrane assembly 202 through suction. This air is then compressed through the oxygen generator membrane assembly 202, meaning that the oxygen generator motor M generates a negative pressure on the permeate side Y of the oxygen generator membrane assembly 202. This negative pressure draws the air from the permeate side Z of the oxygen generator membrane through the oxygen generator membrane assembly 202. The oxygen generator membrane assembly 202 generates oxygen based on the differences in the solubility and diffusion properties of different gas molecules within it. Specifically, oxygen molecules pass through the oxygen generator membrane assembly 202 preferentially than nitrogen molecules and accumulate on the permeate side Y. The oxygen concentration sensor 204 samples the oxygen concentration of the oxygen enrichment tube 205 at regular intervals.
[0039] In another example, the connection relationship between the rotary motor 203 and the oxygen generating membrane assembly 202 is as follows: Figure 3 As shown, a rotary motor 203 is installed below the oxygen-generating membrane assembly 202 and is used to drive the oxygen-generating membrane assembly 202 to rotate. The rotation of the rotary motor 203 can adjust the angle between the permeate side Z of the oxygen-generating membrane assembly 202 and the air inlet 207 of the oxygen generator. It can be understood that during the operation of the oxygen generator, the air near the permeate side Z of the oxygen-generating membrane assembly 202 is external air entering through the air inlet 207. When external air is actively flowing into the air inlet 207 due to airflow influence, there will be an angle difference between the blown airflow and the surface of the permeate side Z of the oxygen-generating membrane assembly 202, which is the windward angle of the oxygen-generating membrane. The size of the windward angle varies depending on the direction of the blown airflow, and different windward angles will have different effects on the oxygen generation effect of the oxygen-generating membrane.
[0040] When the angle between the air blown in from the air inlet 207 and the oxygen generating membrane assembly 202 hinders the oxygen generating device from achieving its optimal oxygen generating effect, the rotation of the rotary motor 203 can drive the oxygen generating membrane assembly 202 to rotate, thereby adjusting the angle of the oxygen generating membrane assembly and overcoming the obstruction caused by the angle of the air, so that the oxygen generating membrane assembly 202 can rotate to the optimal oxygen generating angle, thereby achieving the best oxygen generating effect.
[0041] A preset angle can be understood as a specified angle within a certain angle range for a rotary motor to rotate in both clockwise and counterclockwise directions. In other words, when the rotary motor rotates to the specified angle value, it is considered to have reached its designated position at that angle.
[0042] Specifically, the oxygen outlet pipeline refers to the transport path of the oxygen enriched in the permeate side Y, for example... Figure 2 The oxygen-enriching pipe 205 and connecting pipe 206 are included. The optimal oxygen-generating angle can be understood as the angle at which the oxygen concentration sensor 204 detects the highest oxygen concentration, indicating the best oxygen generation effect at that angle. In some embodiments, the oxygen-generating membrane is typically a planar membrane; therefore, the optimal oxygen-generating angle is the angle at which the oxygen-generating membrane is perpendicular to the airflow direction.
[0043] Assume there are four preset angles: 60 degrees, 70 degrees, 80 degrees, and 90 degrees. Each preset angle is set relative to a pre-configured coordinate system, for example, 0 degrees is defined as the oxygen-generating membrane surface perpendicular to the air inlet plane. After the oxygen generator 200 starts generating oxygen, the rotary motor 203 first rotates to the 60-degree position and collects the oxygen concentration c1 via the oxygen concentration sensor 204. Then it rotates to the 70-degree position and collects the oxygen concentration c2 via the oxygen concentration sensor 204, and so on, obtaining four oxygen concentrations c1 to c4 corresponding to the four preset angles. If c3 has the highest value, the optimal oxygen-generating angle is determined to be 80 degrees, corresponding to c3. Therefore, the rotary motor is controlled to rotate to the 80-degree position to ensure that the oxygen-generating membrane always generates oxygen at its optimal effect.
[0044] According to the control method of the oxygen generating device of the present invention, after the oxygen generating device starts generating oxygen, the rotary motor is controlled to rotate sequentially at multiple preset angles. Each time the rotary motor rotates to the correct position, the oxygen concentration in the oxygen outlet pipeline of the oxygen generating device is acquired, and the optimal oxygen generating angle is determined based on the oxygen concentration corresponding to the multiple preset angles. This allows the oxygen generating membrane assembly to generate oxygen at the optimal oxygen generating angle. Since the oxygen concentration at the optimal oxygen generating angle is the highest oxygen concentration that the oxygen generating device can achieve under the current operating state, the oxygen generating device can operate under the best oxygen generating effect, improving the oxygen generating effect, oxygen generating efficiency and reliability of the oxygen generating device, providing users with more oxygen, ensuring the product quality of the oxygen generating device, and improving the user experience.
[0045] In some embodiments of the present invention, the control method of the oxygen generating device further includes: step A1 or step A2.
[0046] Step A1 involves determining multiple preset angles based on the relative position between the oxygen generating membrane and the air inlet.
[0047] Step A2 involves determining multiple preset angles based on the historical best oxygen production angle.
[0048] Specifically, the relative position between the oxygen generating membrane and the air inlet can be understood as the azimuth angle of the oxygen generating membrane relative to the air inlet. Different azimuth angles result in different ranges of windward angles. Therefore, this azimuth angle can be used to narrow down the selection range of preset angles to quickly determine the optimal oxygen generating angle. For example, if the air inlet is located directly in front of the oxygen generating membrane, the azimuth angle of the air inlet relative to the oxygen generating membrane is 90 degrees, and the preset angle can be set with 90 degrees as the reference. Another example is if the air inlet is located to the left front of the oxygen generating membrane, which is the middle direction between directly in front and directly left. With directly right as 0 degrees, the azimuth angle of the air inlet relative to the oxygen generating membrane is 135 degrees, and the preset angle can be set with 135 degrees as the reference. It can be understood that when the relative position between the oxygen generating membrane and the air inlet changes, the determined preset angles will also change accordingly.
[0049] The historical best oxygen production angle refers to the angle data of the best oxygen production angle of the oxygen generator that has been statistically analyzed over a period of time. Since the airflow direction at the air inlet may remain unchanged over a period of time, the selection range of the preset angle can be narrowed by referring to the historical best oxygen production angle, so as to determine the best oxygen production angle as soon as possible.
[0050] In this way, by determining multiple preset angles based on the relative position between the oxygen generating membrane and the air inlet or the historical best oxygen generating angle, different ways of confirming the preset angle of the rotary motor can be achieved, which improves the flexibility of preset angle selection and narrows the selection range of preset angles, so as to determine the best oxygen generating angle as soon as possible.
[0051] In some embodiments of the present invention, step A1 may specifically include: determining the target rotation range of the oxygen generating membrane based on the relative position between the oxygen generating membrane and the air inlet; dividing the target rotation range to obtain multiple preset angles.
[0052] Specifically, the target rotation range can be understood as the angle range obtained after filtering out angles exceeding the deflection threshold from the allowable rotation range of the oxygen generating membrane based on the azimuth angle between the oxygen generating membrane and the air inlet. The deflection threshold refers to the rotation threshold for clockwise and counterclockwise rotation with the azimuth angle between the oxygen generating membrane and the air inlet as the central angle. In one example, assuming the azimuth angle between the oxygen generating membrane and the air inlet is 90 degrees and the deflection threshold is 60 degrees, the target rotation range is 30 degrees (90-60) to 150 degrees (90+60). Assuming the azimuth angle between the oxygen generating membrane and the air inlet is 135 degrees and the deflection threshold is 30 degrees, the target rotation range is 105 degrees (135-30) to 165 degrees (135+30). It is understood that the deflection threshold can use different values for clockwise and counterclockwise directions; for example, the first deflection threshold for clockwise rotation is 30 degrees, and the second deflection threshold for counterclockwise rotation is 40 degrees.
[0053] After obtaining the target rotation range, for example, for a target rotation range of 30 degrees to 150 degrees, the target rotation range can be divided into 10-degree increments (gradient values) per rotation of the oxygen generating membrane, thereby obtaining multiple preset angles of 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, 90 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, and 150 degrees; for another example, for a target rotation range of 105 degrees to 165 degrees, it can be divided into 20-degree increments, resulting in multiple preset angles of 105 degrees, 125 degrees, 145 degrees, and 165 degrees.
[0054] It is understood that the preset angles include the endpoint angles of the target rotation range, and the target rotation range can be set and changed. Therefore, the gradient value for dividing the target rotation range can also be increased or decreased accordingly with the set angle value of the target rotation range. That is, the target rotation range can be divided into 10 degrees, 5 degrees or 1 degree per rotation of the oxygen generating membrane. The specific value is not limited here.
[0055] In this way, by dividing the target rotation range, multiple preset angles are obtained, making the preset angle setting of the rotary motor more reasonable, laying the foundation for subsequent oxygen concentration detection, so as to determine the optimal oxygen production angle as soon as possible.
[0056] In some embodiments of the present invention, step A2 may specifically include: determining the main rotation angle from the historical best oxygen production angle; determining the main rotation range based on the main rotation angle, wherein the main rotation range includes the main rotation angle; dividing the main rotation range to obtain multiple preset angles, wherein the multiple preset angles include the main rotation angle.
[0057] Specifically, the primary rotation angle can be understood as the optimal oxygen production angle that appears most frequently in the statistically analyzed historical best oxygen production angle variation patterns. The primary rotation range can be understood as the angular range formed by the rotation thresholds of the oxygen production membrane in clockwise and counterclockwise rotations based on the primary rotation angle. For example, it can be an angular range with the primary rotation angle as the central angle and both clockwise and counterclockwise rotation thresholds being 30 degrees. In one example, the primary rotation angle is determined to be 30 degrees from the historical best oxygen production angles. Based on this primary rotation angle of 30 degrees, the clockwise and counterclockwise rotation thresholds are both 20 degrees. Therefore, the primary rotation range is 10 degrees to 50 degrees. Furthermore, the primary rotation range is divided into 5-degree intervals per rotation of the oxygen production membrane, resulting in multiple preset angles of 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, and 50 degrees.
[0058] It is understandable that when determining the main rotation range based on the main rotation angle, multiple preset angles can be obtained more accurately based on the statistically analyzed historical best oxygen production angle variation patterns.
[0059] In this way, by dividing the main rotation range, multiple preset angles are obtained, making the preset angle setting of the rotary motor more reasonable. This lays the foundation for subsequent oxygen concentration detection, allowing the optimal oxygen production angle to be determined as soon as possible, thus improving the efficiency of oxygen concentration detection.
[0060] In some embodiments of the present invention, the step S13 of starting to acquire the oxygen concentration in the oxygen outlet pipeline of the oxygen generating device may specifically include: continuously acquiring the oxygen concentration in the oxygen outlet pipeline of the oxygen generating device until a first preset time period is reached; and determining the oxygen concentration at the current preset angle based on the oxygen concentration acquired within the first preset time period.
[0061] Specifically, the first preset duration can be 1 minute, 5 seconds, 15 seconds, or other values, and is not limited here. In some embodiments, the average value of the oxygen concentration obtained within the first preset duration is calculated, and this average value is determined as the oxygen concentration at the current preset angle.
[0062] In this way, by continuously acquiring the oxygen concentration within the first preset time period, the acquired oxygen concentration value is relatively stable. At the same time, it can also avoid the presence of pipelines in the oxygen generator causing the detected oxygen concentration value to be inaccurate, thereby improving the accuracy of oxygen concentration detection at the current preset angle.
[0063] In some embodiments of the present invention, step S15 may specifically include: generating angle-concentration coordinate points based on multiple preset angles and corresponding oxygen output concentrations; fitting the coordinate points to obtain an angle-concentration variation curve; determining the highest oxygen output concentration from the variation curve; and determining the optimal oxygen production angle based on the highest oxygen output concentration.
[0064] Specifically, fitting can be understood as expressing the relationship between the preset angle and the oxygen concentration using a function curve, based on the acquired preset angle data and oxygen concentration data. The highest oxygen concentration can be understood as the oxygen concentration data with the largest value detected by the oxygen concentration sensor among the oxygen concentration data.
[0065] In some embodiments, the preset angle data and the oxygen concentration data correspond at the time of acquisition. The angle-concentration coordinate points can be marked by plotting points in a first coordinate system based on the acquisition time. The vertical axis of the first coordinate system can represent the oxygen concentration value, and the horizontal axis of the first coordinate system can represent the preset angle value. Then, a curve is plotted based on the angle-concentration coordinate points and fitted to it so that as many coordinate points as possible are located on the angle-concentration change curve. Next, the coordinate point with the largest oxygen concentration value in the angle-concentration change curve is found and determined as the highest oxygen concentration data point. Finally, the angle value of the horizontal axis coordinate corresponding to the highest oxygen concentration data point is determined and the angle value is determined as the optimal oxygen production angle.
[0066] For example, five preset angles are given: 30 degrees, 35 degrees, 40 degrees, 45 degrees, and 50 degrees. These correspond to five concentration values c1 to c5, which are 49%, 52%, 51%, 48%, and 47%, respectively. Before fitting, the maximum concentration among c1 to c5 is c2 = 52%, at which point the optimal oxygen production angle is 35 degrees. After fitting, the maximum concentration is found to be c0 = 52.8%, corresponding to an angle of 34.3 degrees. Therefore, 34.3 degrees is taken as the optimal oxygen production angle.
[0067] Furthermore, after determining the highest oxygen concentration using the fitted curve, the data point of the highest oxygen concentration can be detected. For example, the rotary motor can be controlled to rotate to the angle value corresponding to the highest oxygen concentration and the oxygen concentration can be detected. If the measured oxygen concentration is higher than the oxygen concentration data at any preset angle, the angle value corresponding to the highest oxygen concentration determined after fitting is determined as the optimal oxygen production angle. If the measured oxygen concentration is not higher than the oxygen concentration data at all preset angles, the angle value corresponding to the highest oxygen concentration among all preset angles is taken as the optimal oxygen production angle. In this way, by fitting multiple preset angles and their corresponding oxygen concentrations, the highest oxygen concentration higher than the oxygen concentration at all preset angles can be identified from the fitted curve, improving the accuracy of the optimal oxygen production angle detection and maximizing the oxygen concentration at the finally selected oxygen production angle. In addition, the highest oxygen concentration obtained after fitting is verified to determine its accuracy.
[0068] In some embodiments of the present invention, the control method of the oxygen generating device further includes: if the oxygen generating membrane assembly generates oxygen for a duration of a second preset duration at the optimal oxygen generating angle, then the process jumps to step S11 to control the rotary motor to rotate sequentially at multiple preset angles in order to redetermine the optimal oxygen generating angle.
[0069] Specifically, the second preset duration can be 3 hours, 4 hours, 5 hours, or other values, and is not limited here. It can be understood that since the direction of the outdoor airflow is constantly changing, in order to ensure that the oxygen generator can still achieve the best oxygen production effect after the direction of the outdoor airflow changes, it is necessary to re-determine the optimal oxygen production angle of the oxygen generator every second preset duration.
[0070] In this way, by setting a second preset duration, the problem of the oxygen generator's optimal oxygen production angle not being adjusted in time when the outdoor airflow direction changes can be avoided, thus improving the reliability of the oxygen generator and enhancing the user experience.

Based on the oxygen concentration corresponding to the multiple preset angles, the optimal oxygen generation angle is determined, allowing the oxygen-generating membrane assembly to generate oxygen at the optimal angle.

[0101] It should be noted that the above explanation of the embodiments and beneficial effects of the control method for the oxygen generating device is also applicable to the computer-readable storage medium of the embodiments of the present invention. To avoid redundancy, it will not be elaborated in detail here.
[0102] To achieve the above embodiments, this invention also proposes an oxygen generating device. Figure 6 This is a structural block diagram of an oxygen generating device according to an embodiment of the present invention. Figure 6 As shown, the oxygen generating device 100 includes a memory 102 and a processor 104. The memory 102 stores a computer program 106. When the processor 104 executes the computer program 106, it implements the control method of the oxygen generating device in any of the above embodiments.
[0103] According to the oxygen generating device 100 of the present invention, after the oxygen generating device starts generating oxygen, the rotary motor is controlled to rotate sequentially at multiple preset angles. Each time the rotary motor rotates to the correct position, the oxygen concentration in the oxygen outlet pipeline of the oxygen generating device is acquired, and the optimal oxygen generating angle is determined based on the oxygen concentration corresponding to the multiple preset angles. This allows the oxygen generating membrane assembly to generate oxygen at the optimal oxygen generating angle. Since the oxygen concentration at the optimal oxygen generating angle is the highest oxygen concentration that the oxygen generating device can achieve under the current operating state, the oxygen generating device can operate under the best oxygen generating effect, improving the oxygen generating effect, oxygen generating efficiency and reliability of the oxygen generating device, providing users with more oxygen, ensuring the product quality of the oxygen generating device, and improving the user experience.
[0104] For example, when the control program 106 of the oxygen generator 100 is executed by the processor 104, the following steps S11, S13, S15 and S17 of the control method of the oxygen generator 100 are implemented.
[0105] S11: After the oxygen generator starts producing oxygen, control the rotary motor to rotate sequentially at multiple preset angles.

[0108] S17: By controlling the rotary motor, the oxygen generating membrane assembly generates oxygen at the optimal oxygen generating angle.
[0109] It should be noted that the above-described embodiments and explanations of the beneficial effects of the control method for the oxygen generating device also apply to the oxygen generating device 100 of the present invention. To avoid redundancy, they will not be elaborated in detail here.
[0110] To achieve the above embodiments, this invention also proposes an oxygen generating device, the connection diagram of which is shown below. Figure 2 As shown, the oxygen generating device 200 includes a rotary motor 203, an oxygen generating membrane assembly 202, an oxygen generating motor M, and a controller, and the oxygen generating device 200 is provided with an air inlet.
[0111] The oxygen-generating motor M drives the airflow to the oxygen-generating membrane assembly 202 for oxygen generation. The rotary motor 203 drives the oxygen-generating membrane assembly 202 to rotate, adjusting the angle between the permeate side Z of the oxygen-generating membrane assembly 202 and the air inlet 207. The oxygen-generating membrane assembly 202, mounted on the rotary motor 203, includes an oxygen-generating membrane. The rotary motor can be a stepper motor or an angle motor, and the oxygen-generating membrane can be a selective permeation membrane.
[0112] The controller can be a microcontroller (MCU) used to control the rotary motor 203 to rotate sequentially at multiple preset angles after the oxygen generator 200 starts generating oxygen. Each time the rotary motor 203 reaches its designated position, it acquires the oxygen concentration in the oxygen outlet pipeline of the oxygen generator 200. Based on the oxygen concentration corresponding to the multiple preset angles, it determines the optimal oxygen generation angle and controls the rotary motor 203 to ensure that the oxygen generating membrane assembly 202 generates oxygen at the optimal angle. The oxygen outlet pipeline can include a connecting pipe 206 and an oxygen enrichment pipe 205. The two ends of the connecting pipe 206 are connected to the permeate side Y of the oxygen generating membrane assembly 202 and the oxygen input end X of the oxygen generator motor M, respectively. The oxygen enrichment pipe 205 is connected to the output end of the oxygen generator motor M, which is located downstream of the gas path. The oxygen concentration sensor 204 is installed inside the oxygen enrichment pipe 205.
[0113] According to the oxygen generator 200 of this embodiment, after the oxygen generator starts generating oxygen, the rotary motor is controlled to rotate sequentially at multiple preset angles. Each time the rotary motor rotates to the correct position, the oxygen concentration in the oxygen outlet pipeline of the oxygen generator is acquired, and the optimal oxygen generation angle is determined based on the oxygen concentration corresponding to the multiple preset angles. This allows the oxygen generating membrane assembly to generate oxygen at the optimal oxygen generation angle. Since the oxygen concentration at the optimal oxygen generation angle is the highest oxygen concentration that the oxygen generator can achieve under the current operating state, the oxygen generator can operate under the best oxygen generation effect, improving the oxygen generation effect, oxygen generation efficiency, and reliability of the oxygen generator, providing users with more oxygen, ensuring the product quality of the oxygen generator, and improving the user experience.

[0116] In some embodiments of the present invention, the controller determines multiple preset angles based on historical best oxygen production angles by: determining a main rotation angle from historical best oxygen production angles; determining a main rotation range based on the main rotation angle, wherein the main rotation range includes the main rotation angle; and dividing the main rotation range to obtain multiple preset angles, wherein the multiple preset angles include the main rotation angle.
[0117] In some embodiments of the present invention, the controller begins to acquire the oxygen concentration in the oxygen outlet pipeline of the oxygen generator 200 by continuously acquiring the oxygen concentration in the oxygen outlet pipeline of the oxygen generator 200 until a first preset time is reached; and determines the oxygen concentration at the current preset angle based on the oxygen concentration acquired within the first preset time.
[0118] In some embodiments of the present invention, the controller determines the optimal oxygen production angle by: generating angle-concentration coordinate points based on multiple preset angles and corresponding oxygen output concentrations; fitting the coordinate points to obtain an angle-concentration variation curve; determining the highest oxygen output concentration from the variation curve; and determining the optimal oxygen production angle based on the highest oxygen output concentration.
[0119] In some embodiments of the present invention, the controller is further configured to: if the oxygen generation membrane assembly generates oxygen for a duration of a second preset duration at the optimal oxygen generation angle, then proceed to the step of controlling the rotary motor to rotate sequentially at multiple preset angles, so as to redetermine the optimal oxygen generation angle.
