[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In order to solve the problem that the existing air bag will bulge if the pressure is too high during actual use, and then burst due to falling or impact during transportation, please refer to Figure 1-Figure 8 , this embodiment provides the following technical solutions: An inflatable bag capable of intelligently monitoring air valve pressure comprises an inflatable bag body 1, a vent pipe 2 and an air column 3. The vent pipes 2 are equidistantly arranged on the surface of the inflatable bag body 1. The top of the vent pipes 2 is communicated with the inflation port 4 of the inflatable bag body 1, and the bottom of the vent pipes 2 is communicated with the air column 3. A sealing structure 6 is arranged inside the vent pipe 2, an air valve 9 is arranged below the sealing structure 6, and a pressure monitor 5 is arranged below the air valve 9. A Velcro fur surface 7 is arranged at one end of the inflatable bag body 1, and a Velcro thorn surface 8 is arranged at the other end of the inflatable bag body 1. The Velcro thorn surface 8 and the Velcro fur surface 7 are used to bond the inflatable bag body 1. The operation is simple and convenient to use. The pressure is monitored in real time by using the pressure monitor 5 to avoid rupture or insufficient inflation of the inflatable bag body 1 due to overcharging or undercharging, thereby extending its service life.

[0024] The sealing structure 6 includes a fixed plate 61, a movable plate 62, a hydraulic rod 63, a mounting member 64 and a fixing member 65. The mounting member 64 is rotatably mounted on the fixed plate 61, and the hydraulic rod 63 is fixedly mounted on the mounting member 64. One end of the hydraulic rod 63 away from the mounting member 64 is mounted on the movable plate 62 through the fixing member 65. The movable plate 62 is movably mounted in the fixed plate 61, and the fixed plate 61 is fixedly mounted on the inner wall of the ventilation pipe 2.

[0025] During operation, the air column 3 is inflated by connecting the air pump to the inflation port 4. At this time, the hydraulic rod 63 works to shrink the movable plate 62 into the fixed plate 61, and the sealing structure 6 is opened, so that the gas can smoothly enter the air column 3. At the same time, the pressure monitor 5 works. When the pressure in the air column 3 is monitored to be close to the predicted pressure, the sealing structure 6 is closed to ensure that the pressure of the inflatable bag body 1 is always within the pressure threshold range, avoiding the risk of explosion of the inflatable bag body 1 due to excessive pressure, so that the packaged products are damaged during transportation.

[0026] The air valve 9 includes an outer tube 91, an inner tube 92, a core tube 93, a spring 94, a sealing gasket 95, a limit plate 96 and an insertion rod 97. The inner tube 92 is sleeved inside the outer tube 91, and the core tube 93 is installed on the inner thread of the inner tube 92. A limit plate 96 is provided at the bottom of the core tube 93, and a through hole is provided on the limit plate 96.

When the sealing gasket 95 fits with the bottom of the core tube 93, the sealing gasket 95 closes the core tube 93.

[0027] A pressure plate 921 is fixed to the outside of the inner tube 92, a sealing strip 922 is fixed to the lower surface of the pressure plate 921, and a groove 911 is provided on the upper surface of the outer tube 91. The sealing strip 922 is installed in the groove 911 to seal the air valve 9, thereby improving the sealing effect and avoiding air leakage during inflation, which affects the normal inflation of the inflatable bag body 1.

[0028] When the sealing pad 95 is in close contact with the bottom of the core tube 93, the air valve 9 is in a sealed state. When the inflatable bag body 1 is inflated, the sealing pad 95 is pushed away from the bottom of the core tube 93 under the action of air pressure, and the interior of the air column 3 is inflated. When the inflation is completed, the sealing pad 95 loses the thrust and returns to the bottom of the core tube 93 under the action of the spring 94, thereby sealing the air valve 9.

[0029] The pressure monitor 5 is provided with a control system, which includes: A data acquisition module, used to acquire the effective area and inflation force of the inflatable bag body 1, and calculate the standard pressure of the inflatable bag body 1 according to the effective area and inflation force of the inflatable bag body 1; A monitoring module, used to monitor the pressure in the inflatable bag body 1 in real time and continuously collect pressure data, and transmit the collected pressure data to the judgment module; The analysis module is used to determine whether the real-time monitored pressure data exceeds the preset pressure threshold and transmit the judgment result to the control module.

[0030] The control module is used to feedback and adjust the pressure in the gas column 3 through the hydraulic rod 63 according to the air pressure data monitored by the monitoring module.

[0031] By monitoring the pressure of the inflatable bag body 1 in real time, it is possible to understand the pressure condition of the inflatable bag body 1 during the inflation process, and adjust the gas entry pressure of the air valve 9 according to the real-time pressure condition of the inflatable bag body 1, thereby avoiding the risk of explosion of the inflatable bag body 1 due to excessive pressure, thereby causing damage to the packaged product during transportation.

[0032] Preferably, the hydraulic rod 63 comprises: A first control rod, one end of which is fixedly connected to the mounting member 64, and the first control rod is hollow inside; A second telescopic rod, one end of which is built into the first control rod and is slidably connected to the other end of the first control rod; A driving module, built into the second telescopic rod, for providing driving force for the movement of the hydraulic rod 63; A control module, which is in communication with the driving module, the control module issues instructions to control the movement of the driving module, and the control module is in communication with the control system; A first position distance measuring sensor, built into the inner wall of the other end of the first control rod, used to measure the sliding distance of the second telescopic rod during the process of the second telescopic rod telescopically sliding relative to the first control rod, the first position distance measuring sensor being communicatively connected with the control module; A second laser distance measuring sensor is built into the inner wall of the connecting end of the first control rod and the mounting member 64, and is used to measure the sliding distance of the second telescopic rod during the process of the second telescopic rod telescopically sliding relative to the first control rod. The second laser distance measuring sensor is communicatively connected with the control module; a calculation and analysis module, configured to receive a first sliding distance detected by the first position ranging sensor, and receive a second sliding distance detected by the second laser ranging sensor, calculate an arithmetic mean of the first sliding distance and the second sliding distance, obtain a calibration sliding distance, and transmit the calibration sliding distance information to the control module; The control module adjusts the driving movement of the second telescopic rod by the driving module in combination with the calibrated sliding distance.

[0033] The principle and effect of the above technical solution are as follows: by setting the hydraulic rod 63 as two parts, the first control rod and the second telescopic rod, and the second telescopic rod slidingly moves relative to the first control rod, the length of the entire hydraulic rod 63 can be adjusted. When the entire length of the hydraulic rod 63 changes, the movable plate 62 will be driven to move synchronously. Specifically, when the second telescopic rod is retracted relative to the first control rod, the second telescopic rod drives the movable plate 62 to retract into the fixed plate 61. When the movable plate 62 moves, the hydraulic rod 63 rotates along the mounting member 64, so that the sealing structure 6 can be smoothly opened, so that the gas can smoothly enter the gas column 3. When the second telescopic rod is relative to the first control rod, the movable plate 62 can be driven to move synchronously. When the first control rod is extended, the second telescopic rod drives the movable plate 62 to extend from the lower end of the fixed plate 61, gradually sealing the sealing structure 6, so that the gas can no longer enter the gas column 3. The telescopic length of the second telescopic rod corresponds to the rotation angle of the movable plate 62. Combined with the length of the entire telescopic rod and the size of the movable plate 62 and the fixed plate 61, the two have a matching relationship. The driving module is used to provide driving force to the second telescopic rod, drive the second telescopic rod to slide relative to the first control rod, thereby adjusting the length of the entire hydraulic rod 63. The driving module is controlled and started by the control module to realize intelligent opening and closing without manual operation. The control module can Accepting the command of the control system, that is, when the control system determines that the sealing structure 6 needs to be opened or closed, the control module sends a command to start the adjustment, and the control module controls the movement of the driving module to drive the second telescopic rod to slide relative to the first control rod. In this process, the sealing structure 6 is opened or closed, wherein the sliding distance of the second telescopic rod directly affects the degree of adjustment, so the sliding distance of the second telescopic rod is detected by the first position ranging sensor and the second laser ranging sensor at the same time. The two different types of ranging sensors are mainly used to calibrate the error generated in the ranging process. The first sliding distance and the second sliding distance detected by the first position ranging sensor and the second laser ranging sensor are obtained respectively, and the calibrated sliding distance is obtained by calculating the arithmetic mean. The calibrated sliding distance can be matched with the rotation angle or rotation condition of the movable plate 62 relative to the fixed plate 61 through conversion, and the matching relationship can be pre-stored in the control module. Therefore, the control module controls the driving module to drive the second telescopic rod to realize the opening and closing of the sealing structure 6 and the adjustment of the opening size, thereby improving the progress and effect of inflation, and can further realize the adjustment of the pressure in the gas column 3, which has high intelligence.

[0034] Specifically, the control system also includes: A pressure value real-time monitoring module is used to monitor the pressure in the inflatable bag body 1 in real time, and obtain the pressure change rate according to the pressure in the inflatable bag body 1 obtained by real-time monitoring; A pressure change rate comparison module, used to compare the pressure change rate in the inflatable bag body 1 with a preset pressure change rate threshold; A pressure change stability coefficient acquisition module is used to retrieve the pressure value in the inflatable bag body 1 collected each time and the current pressure change rate to obtain the pressure change stability coefficient when the pressure change rate in the inflatable bag body 1 exceeds a preset pressure change rate threshold; The pressure change stability coefficient is obtained by the following formula: Where S represents the pressure change stability coefficient; m represents the total number of pressure collection times in the inflatable bag body 1; R b represents the standard deviation of the pressure change rate corresponding to the pressure acquisition in the inflatable bag body 1 for m times; R fmax represents the maximum floating value of the pressure change rate corresponding to the pressure acquisition in the inflatable bag body 1 for m times; P b represents the standard deviation of the pressure values ​​corresponding to the pressure collected in the inflatable bag body 1 m times; P fmax represents the maximum floating value of the pressure value corresponding to the pressure collection in the inflatable bag body 1 for m times; R represents the pressure change rate in the inflatable bag body 1 corresponding to the pressure change rate threshold value exceeding the preset pressure change rate threshold; R y Indicates the preset pressure change rate threshold, P i Indicates the pressure value corresponding to the pressure collection in the inflatable bag body 1 for the i-th time; The data acquisition frequency adjustment module is used to adjust the data acquisition frequency of the current pressure in the inflatable bag body 1 by using the pressure change stability coefficient to obtain the adjusted data acquisition frequency; wherein the adjusted data acquisition frequency is obtained by the following formula: Among them, F t represents the data acquisition frequency after adjustment; F0 represents the data acquisition frequency before adjustment; S represents the pressure change stability coefficient; S y Indicates the preset pressure change stability coefficient reference value; R fmin represents the minimum floating value of the pressure change rate corresponding to the pressure acquisition in the inflatable bag body 1 for m times; P fmax Indicates the maximum floating value of the pressure value corresponding to the pressure collection in the inflatable bag body 1 m times; P fmin Indicates the minimum floating value of the pressure value corresponding to the pressure collection in the inflatable bag body 1 for m times; R b Indicates the standard deviation of the pressure change rate corresponding to the pressure acquisition in the inflatable bag body 1 m times; The data collection control module is used to control the collection operation of the pressure value in the inflatable bag body 1 according to the adjusted data collection frequency.

[0035] The technical effect of the above technical solution is: through the real-time monitoring module of pressure value, the system can continuously and accurately monitor the pressure change in the inflatable bag body 1, and calculate the pressure change rate in real time. This function provides a real-time and reliable data basis for subsequent decision-making, ensuring that the system can respond to abnormal pressure changes in the first time. The pressure change rate comparison module compares the real-time monitored pressure change rate with the preset threshold value, and can accurately determine whether the pressure state in the inflatable bag body 1 is abnormal. This precise evaluation capability helps to avoid equipment damage or performance degradation caused by excessive pressure fluctuations, thereby improving the stability and reliability of the system. When the pressure change rate exceeds the preset threshold, the system calculates the stability coefficient through the pressure change stability coefficient acquisition module. This indicator combines multiple factors such as the standard deviation of the pressure change rate, the floating maximum value, the standard deviation of the pressure value, and the floating maximum value, and can fully reflect the stability and controllability of the pressure change in the inflatable bag body 1. This comprehensive evaluation method can more accurately reflect the actual situation than a single indicator, and helps the system make more reasonable decisions. The data acquisition frequency adjustment module uses the pressure change stability coefficient to dynamically adjust the data acquisition frequency, realizing the intelligence and adaptability of data acquisition. When the pressure changes are relatively stable, the acquisition frequency is reduced to reduce resource consumption; when the pressure changes violently, the acquisition frequency is increased to capture the pressure dynamics more accurately. This dynamic adjustment mechanism not only improves the efficiency of data acquisition, but also ensures the accuracy and integrity of the data. The data acquisition control module controls the pressure value acquisition operation in the inflatable bag body 1 according to the adjusted data acquisition frequency, realizing precise control of data acquisition. This control mechanism can ensure that the system can meet the requirements of data acquisition accuracy and real-time performance in practical applications while maintaining efficient operation. Overall, this technical solution significantly improves the overall performance of the pressure control system of the inflatable bag body 1 through multiple links such as real-time monitoring, accurate evaluation, comprehensive index calculation, dynamic adjustment and data acquisition control. It not only improves the stability and reliability of the system, but also reduces resource consumption and improves the efficiency and accuracy of data acquisition. These performance improvements are of great significance in improving product quality, extending equipment life and reducing maintenance costs.

[0036] In summary, the application of this technical solution in the pressure control system of the inflatable bag body 1 not only realizes real-time monitoring and accurate evaluation of pressure changes, but also significantly improves the overall performance and reliability of the system by dynamically adjusting the data acquisition frequency and efficient data acquisition control.

If it is within the pressure threshold range, there is no need to control the sealing structure 6 to work; If it approaches the pressure threshold, the sealing structure 6 is controlled to slowly reduce the opening until the pressure threshold is reached and the sealing structure 6 is closed. By adjusting the inflation pressure, it can better meet the packaging needs of various goods and ensure that the goods are optimally cushioned and protected during transportation.

[0042] Working principle: When using an inflatable bag capable of intelligently monitoring the air valve pressure of the present invention, Figure 1-Figure 8 , including the following steps: Step 1: Connect the air pump to the air inlet 4 to inflate the air column 3. At this time, the hydraulic rod 63 works to shrink the movable plate 62 into the fixed plate 61, open the sealing structure 6, and allow the gas to smoothly enter the air column 3; Step 2: At this time, under the action of air pressure, the sealing pad 95 is pushed away from the bottom of the outer tube 91 to inflate the interior of the air column 3; Step 3: The pressure monitor 5 continuously monitors the pressure in the gas column 3 and analyzes and judges the monitoring results; Step 4: If the judgment result is that the pressure threshold of the inflatable bag body 1 is exceeded, the pressure control command of the inflatable bag body 1 is triggered, and the hydraulic rod 63 is controlled to work to pull the movable plate 62 out of the fixed plate 61, close the opening, and do not inflate the gas column 3; Step 5: If the judgment result is that the pressure does not exceed the pressure threshold of the inflatable bag body 1, no response is made and the sealing structure 6 opens normally; Step six: If the judgment result is that the pressure does not exceed the pressure threshold of the inflatable bag body 1 and is close to the pressure threshold, the hydraulic rod 63 is controlled to work to pull the movable plate 62 to the outside of the fixed plate 61 to reduce the opening, and the sealing structure 6 is closed after the pressure threshold is reached, so that the pressure of the inflatable bag body 1 is always within the pressure threshold range, which can not only effectively reduce the loss of the inflatable bag body 1, but also avoid rupture or insufficient inflation of the inflatable bag body 1 due to overcharging or undercharging, thereby extending its service life.

[0043] Step 7: After the inflation is completed, the sealing pad 95 loses its thrust and returns to the bottom of the outer tube 91 under the action of the spring 94 to seal the air valve 9.

[0044] In summary, the inflatable bag of the present invention can intelligently monitor the pressure of the air valve, and by real-time pressure monitoring of the inflatable bag body 1, it is possible to understand the pressure condition of the inflatable bag body 1 during the inflation process, and adjust the gas entry pressure of the air valve 9 according to the real-time pressure condition of the inflatable bag body 1. When the pressure in the gas column 3 is monitored to be close to the predicted pressure, the sealing structure 6 is closed to ensure that the pressure of the inflatable bag body 1 is always within the pressure threshold range. This can not only effectively reduce the loss of the inflatable bag body 1, avoid rupture or insufficient inflation of the inflatable bag body 1 due to overfilling or underfilling, thereby extending its service life, but also by adjusting the inflation pressure, it can better adapt to the packaging needs of various goods, ensure that the goods are optimally cushioned and protected during transportation, and avoid the risk of explosion of the inflatable bag body 1 due to excessive pressure, causing damage to the packaged products during transportation.
