Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to an intelligent gas diversion method for a gas diversion device. Background Technology

[0002] Gas diversion devices can be used in air wave or air pressure massage products. These products require inflation and deflation to achieve the massage function. These products generally have at least two separate user bodies. Therefore, in order to achieve synchronous massage for different user bodies at the same time, the same inflation / deflation device is needed to control the inflation or deflation of different user areas of multiple user bodies simultaneously through a solenoid valve. Therefore, in order to ensure the uniformity of airflow distribution among different user bodies and to ensure the massage intensity, a gas diversion device needs to be set between the inflation / deflation device and the user body.

[0003] In existing technologies, the massage intensity for different usage areas is typically controlled synchronously, with only one solenoid valve. This prevents adjustment of the massage intensity based on the needs of different usage areas. Different usage areas on the user unit have different air paths, meaning they are controlled by the same solenoid valve. The gas diversion device requires two diversions: first, the gas is diverted after passing through the solenoid valve and simultaneously enters different air paths; then, a second diversion occurs, where the airflow diverted to the same air path is further diverted to different user units. Neither of these diversions allows for intelligent control, making it impossible to adjust the massage intensity of different usage areas independently. Therefore, it is necessary to propose an intelligent gas diversion method for the gas diversion device to at least partially solve the problems existing in the prior art. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, the present invention provides an intelligent gas diversion method for a gas diversion device, the gas diversion device comprising: a diversion body having n connectors thereon, each connector being connected to m interfaces through the diversion body; wherein n is greater than or equal to 2, and m is greater than or equal to 2; the method comprising:

[0006] n connectors are connected to a main air path through n branch air paths. The main air path is connected to the inflation module. A solenoid valve is installed on each of the branch air paths, and a flow sensor is installed on the branch air path where the solenoid valve is connected to the connector.

[0010] Preferably, the output flow rate of each interface is related to the preset flow rate of the corresponding branch gas path. During the inflation process when the equipment is working normally, the actual flow rate of each branch gas path is fed back to the main control module through the flow sensor. The main control module determines whether the error between the actual flow rate and the preset flow rate is within the preset error range. If it is within the preset error range, there is no need to adjust the opening of the solenoid valve. If it is not within the preset error range, the main control module adjusts the opening of the corresponding solenoid valve in real time to keep the error between the actual flow rate and the preset flow rate of the corresponding branch gas path within the preset error range.

[0031] Based on the average value of the maximum actual conditions of the n usage areas corresponding to the n connectors, and the maximum actual conditions of the n usage areas, the inflation uniformity of the n connectors is obtained.

[0032] Preferably, based on a comparison between the actual conditions of the usage area and the set conditions, the opening degree of all solenoid valves is adjusted proportionally according to the ratio of the output set flow rate of each interface, including:

If not, then adjust the opening of all solenoid valves proportionally according to the ratio of the output set flow of each interface based on the maximum deviation. If so, then update the set opening of the solenoid valves according to steps S210 to S230.

[0037] Compared with the prior art, the present invention has at least the following beneficial effects:

[0038] The intelligent gas diversion method of the gas diversion device described in this invention adjusts the opening degree of the corresponding solenoid valve according to the output set flow rate required by the interface. The gas flow rate diverted from the main gas path to each branch gas path can be adjusted by the opening degree of the solenoid valve, which can perform uniform and non-uniform diversion to meet the needs of individual adjustment of the massage intensity in different use areas of the user body, thereby improving the intelligence of use.

[0039] The intelligent gas diversion method of the gas diversion device described in this invention, other advantages, objectives and features of this invention will be apparent in part from the following description, and in part will be understood by those skilled in the art through study and practice of this invention.

[0043] Figure 3 This is a flowchart of step S2 in the intelligent gas diversion method of the gas diversion device described in this invention;

[0044] Figure 4 This is a flowchart of step S210 in the intelligent gas diversion method of the gas diversion device of the present invention. Detailed Implementation

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0046] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0047] like Figure 1 As shown, this invention provides an intelligent gas diversion method for a gas diversion device. The gas diversion device includes: a diversion body with n connectors, each connector being connected to m interfaces through the diversion body; wherein n is greater than or equal to 2, and m is greater than or equal to 2; the method includes:

[0048] n connectors are connected to a main air path through n branch air paths, the main air path is connected to the inflation module, and a solenoid valve is installed on each of the branch air paths;

[0049] Based on the output flow rate of each interface, the opening degree of the solenoid valve corresponding to that interface is adjusted by the main control module.

[0050] Furthermore, the interface is connected to the air supply end of the device, and each connector has m interfaces corresponding to m main bodies of the device, and n connectors corresponding to n usage areas of a main body.

[0051] The inflation module simultaneously inflates and deflates n usage areas of the main body in a cyclical manner, with inflation occurring at preset time intervals and each inflation completed within a set time.

[0052] The opening degree of the solenoid valve is directly proportional to the gas flow rate at the interface. The output set flow rate of the interface is related to the massage intensity (set pressure) required for the corresponding use area. Before using the device, different massage intensities (set pressures) can be set for different use areas. Based on the magnitude of the massage intensity and the relationship between massage intensity and flow rate, the output set flow rate of the interface is obtained, and then the opening degree of the solenoid valve is adjusted. For example, if the output set flow rate of the interface is larger, then the massage intensity obtained after inflating the use area with this output set flow rate within the set time will be larger.

[0053] The above technical solution allows for the adjustment of the opening degree of the corresponding solenoid valve based on the required output flow rate of the interface. The opening degree of the solenoid valve can be used to adjust the gas flow rate from the main air path to each branch air path, enabling both uniform and non-uniform flow distribution. This allows for individual adjustment of the massage intensity in different areas of the user's device, enhancing the intelligence of the device.

[0054] Furthermore, the output flow rate of each interface is related to the preset flow rate of the corresponding branch gas path. During the inflation process when the equipment is working normally, the actual flow rate of each branch gas path is fed back to the main control module through the flow sensor. The main control module determines whether the error between the actual flow rate and the preset flow rate is within the preset error range. If it is within the preset error range, there is no need to adjust the opening of the solenoid valve. If it is not within the preset error range, the main control module adjusts the opening of the corresponding solenoid valve in real time to keep the error between the actual flow rate and the preset flow rate of the corresponding branch gas path within the preset error range.

[0055] To achieve precise flow control and ensure that each interface is filled with air according to the set output flow rate, the flow rate of each branch air path is monitored in real time by a flow sensor during normal operation of the equipment. Since the flow rate of each branch air path is related to the flow rate of its corresponding interface, the set output flow rate of the interface is converted to the preset flow rate of each branch air path. The flow rate of the branch air path is then monitored by the flow sensor. The actual flow rate is then compared with the preset flow rate, and the opening of the solenoid valve is adjusted in real time by the main control module based on the comparison result to achieve precise flow control.

[0056] like Figure 2 As shown, in one embodiment, based on the output flow rate of each interface, the opening degree of the solenoid valve corresponding to that interface is adjusted by the main control module, including:

[0057] S1. Based on the setting conditions of the usage area, determine the output set flow rate of each interface and the ratio of the output set flow rates of each interface;

[0058] S2. Determine the set opening degree of the solenoid valve corresponding to each interface based on the output set flow rate, and then charge it with air;

[0059] S3. After inflation is completed within a set time, the actual conditions of the corresponding area are obtained, and the actual conditions are compared with the set conditions. Based on the comparison results, the opening degree of each solenoid valve is adjusted.

[0060] Furthermore, the opening degree of each solenoid valve is adjusted proportionally according to the ratio of the output set flow rate of each interface.

[0061] Before using the equipment, the set opening degree of n solenoid valves is determined through the above steps. Each solenoid valve is then inflated within a set time period based on its set opening degree. After inflation, the actual conditions of the operating area are obtained and compared with the set conditions. If the comparison result of the actual conditions and the set conditions meets the target range, the inflation and deflation can be cyclically performed based on the determined set opening degrees of the n solenoid valves. If the comparison result of the actual conditions and the set conditions does not meet the target range, it indicates an error in determining the set opening degree of the solenoid valves. The set opening degree of the solenoid valves is then readjusted until the comparison result of the actual conditions and the set conditions meets the target range.

[0062] The actual conditions refer to the actual pressure of the area of ​​use, while the set conditions refer to the set pressure of the area of ​​use.

[0063] During equipment operation, the actual pressure of the operating area is monitored in real time. The main control module adjusts the actual pressure to meet the set pressure. Adjusting the actual pressure is equivalent to adjusting the opening of the solenoid valves. If the set opening of each solenoid valve before equipment operation meets the target range when comparing the actual and set conditions, it indicates that during equipment operation, the actual opening of each solenoid valve can be proportionally adjusted according to the ratio of the output set flow of each interface (corresponding to the ratio of the set opening of each solenoid valve).

[0064] The above technical solution enables precise determination of the gas flow rate from the main gas path to each branch gas path by detecting and adjusting the opening degree of the solenoid valve before the equipment is put into operation. In this way, when the equipment is in operation, the gas flow rate from the main gas path to each branch gas path can be proportionally adjusted by using the actual pressure of the area, ensuring the accuracy of the diversion and improving the convenience of adjusting the solenoid valve during use.

[0065] Furthermore, based on a comparison between the actual conditions of the usage area and the set conditions, the opening degree of all solenoid valves is proportionally adjusted according to the ratio of the output set flow rate of each interface, including:

[0066] Obtain the comparison results of the actual conditions and the set conditions for n usage areas on the same user entity;

[0067] If the comparison results of n usage areas all meet the target range, then the gas is cyclically charged and discharged according to the current solenoid valve setting.

[0068] If the comparison result of at least one usage area does not meet the target range, then obtain the maximum deviation of the comparison result that does not meet the target range relative to the target range, and determine whether adjusting the opening of all solenoid valves proportionally according to the ratio of the output set flow of each interface based on the maximum deviation will cause the comparison result of the other usage areas to exceed the target range. If not, then adjust the opening of all solenoid valves proportionally according to the ratio of the output set flow of each interface based on the maximum deviation. If so, then update the set opening of the solenoid valves according to steps S210 to S230.

[0069] The comparison result is the difference between the actual conditions and the set conditions, denoted as e. The target range is assumed to be (-E, E), where E is a positive number. The deviation of the comparison result from the target range is the difference between e and the minimum value of the target range, -E (where e is less than -E), or the difference between the maximum value of the target range, E, and e (where e is greater than E).

[0070] This section details the method for detecting and adjusting the set opening of the solenoid valve before using the equipment, which involves two scenarios:

[0071] The first type is that if the comparison results of n usage areas all meet the target range, it means that the set opening of all solenoid valves can meet the accurate flow distribution of each branch gas path. Then, when the equipment is working, the set opening of the solenoid valves is determined to perform cyclic charging and discharging and proportional adjustment.

[0072] The second scenario is that if the comparison result of at least one of the n usage areas does not meet the target range, it indicates that the set opening degree of the solenoid valve corresponding to that interface is inaccurate based on the output set flow rate of each interface, and the set opening degree of each solenoid valve needs to be adjusted. There are two ways to adjust the set opening degree of the solenoid valve. The first way is to update the set opening degree of all solenoid valves by adjusting the opening degree of all solenoid valves proportionally, and after the adjustment, the comparison results of all n usage areas meet the target range. The second way is to update the set opening degree of the solenoid valves according to steps S210 to S230. Of course, for the convenience of adjustment, it can be set that as long as the comparison result of at least one usage area does not meet the target range, the second way of updating is used.

[0073] The above method can detect the set opening degree of the solenoid valve and update and adjust it in a timely manner, so as to accurately determine the flow rate of each branch gas path before the equipment is used, realize intelligent gas diversion, meet the different massage pressures of different use areas, and improve the intelligence of the equipment.

[0074] like Figure 3 As shown, further, S2 includes:

[0075] S210. Pre-determine a reference solenoid valve among all solenoid valves, and determine the opening coefficient of each solenoid valve based on the opening degree of the reference solenoid valve.

[0076] S220. Determine the theoretical opening degree of the solenoid valve corresponding to each interface based on the output flow rate of each interface.

[0077] S230. Determine the set opening degree of the solenoid valve based on the theoretical opening degree of the solenoid valve and the corresponding opening degree coefficient.

[0078] Due to various factors, when each solenoid valve is charged with gas at the same opening degree, the actual pressure obtained in the area of ​​use still has errors. In order to ensure the accuracy of the gas flow rate to each branch gas path, the opening degree of all solenoid valves is calibrated according to the actual pressure of the area of ​​use. After determining a reference solenoid valve, the opening degree coefficient of the other solenoid valves relative to the reference solenoid valve is determined. The opening degree coefficient of the reference solenoid valve is 1.

[0079] Since the output flow rate of the interface is directly proportional to the theoretical opening of the solenoid valve, the actual pressure in the area of ​​use may not meet the set pressure after inflation with the theoretical opening of the solenoid valve. This is affected by the specific usage of the equipment and various other factors. Therefore, before each use of the equipment, the opening coefficient of each solenoid valve is re-determined to eliminate influencing factors. This makes the flow rate of gas from the main air path to each branch air path more accurate, thereby improving the precision of the massage intensity in the area of ​​use and enhancing the usage effect.

[0080] like Figure 4 As shown, further, S210 includes:

[0081] S211. Pre-adjust the opening degree of all solenoid valves to the maximum opening degree, and obtain the control signal applied to each solenoid valve by the main control module at the maximum opening degree;

[0082] The control signal is a voltage signal; the opening degree of each solenoid valve is positively correlated with the voltage applied to it, so the voltage signal is used as the control signal to adjust the opening degree of the solenoid valve.

[0083] S212. Simultaneously inflate each usage area at maximum opening within a set time to obtain the maximum actual conditions of each usage area; wherein, the maximum actual conditions are the maximum actual pressure of the usage area obtained by detection.

[0084] S213. Based on the maximum actual conditions of the n usage areas corresponding to the n connectors, obtain the inflation uniformity of the n connectors.

[0085] Further, S213 includes:

[0086] The average of the actual conditions of the same usage area on m user entities is used as the maximum actual condition of the usage area corresponding to a connector.

[0087] Obtain the average of the maximum actual conditions for the n usage areas corresponding to the n connectors;

[0088] Based on the average value of the maximum actual conditions of the n usage areas corresponding to the n connectors, and the maximum actual conditions of the n usage areas, the inflation uniformity of the n connectors is obtained.

[0089] The formula for calculating inflation uniformity is as follows:

[0090]

[0091] Where ε represents inflation uniformity, P ij The actual conditions (actual pressure) of the i-th usage area on the j-th user body corresponding to the i-th connector; It is the average of the actual conditions of the same usage area on m user entities; It is the average of the maximum actual conditions of the n usage areas corresponding to the n connectors;

[0092] The preset requirement is set to ε0. If ε≤ε0, the inflation uniformity meets the preset requirement. If ε>ε0, the inflation uniformity does not meet the preset requirement.

[0093] When each usage area is inflated with the solenoid valve at its maximum opening, the massage force of each usage area is its maximum actual pressure. At this time, theoretically, the gas flow rate from the main air path to each branch air path is equal. However, due to the influence of various factors, the gas flow rate of each branch air path is different, and further judgment is required.

[0094] S214. Determine whether the inflation balance meets the preset requirements. If not, take the minimum value among the n maximum actual conditions as the reference condition, take the solenoid valve corresponding to the reference condition as the reference solenoid valve, take the control signal corresponding to the reference solenoid valve as the reference control signal, and adjust the opening of the remaining solenoid valves so that the inflation balance meets the preset requirements.

[0095] The inflation uniformity can determine whether each solenoid valve can achieve uniform flow distribution under the same opening degree. It can detect the actual situation of the equipment being affected by other factors during operation. If the inflation uniformity does not meet the preset requirements, it indicates that the equipment is greatly affected by other factors during operation. It is necessary to determine the reference solenoid valve and adjust the opening degree of the other solenoid valves to eliminate the influence of various factors on the solenoid valve opening adjustment (inflation flow). If the inflation uniformity meets the preset requirements, it indicates that the equipment is not affected by other factors during operation.

[0096] S215. When the inflation balance meets the preset requirements, obtain the control signal applied by the main control module to each of the other solenoid valves, and use the control signal as the control signal for the maximum opening of the solenoid valve.

[0097] After adjusting the opening of the remaining solenoid valves, the control signal, i.e. the voltage signal, can be obtained from the solenoid valves, which serves as the voltage signal for the maximum opening of each solenoid valve.

[0098] S216. Based on the reference control signal of the reference solenoid valve and the control signal of the maximum opening of the other solenoid valves, obtain the opening coefficient of each solenoid valve.

[0099] If the opening coefficient of the reference solenoid valve is 1, then the opening coefficients of the other solenoid valves are obtained by the ratio of the control signal for their maximum opening to the reference control signal.

[0100] By following the steps above, the opening coefficient of each solenoid valve can be accurately determined when the equipment is in operation, thereby eliminating the influence of other factors on the air flow rate and achieving precise diversion from the main air path to the branch air path, thus enabling more precise adjustment of the actual pressure in each usage area.

[0101] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. Other modifications can be easily made by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
