Description

Technical Field

[0001] This invention relates to the field of laser therapy device technology, and more specifically, to a laser therapy device coupler protection system. Background Technology

[0002] Laser therapy devices are essential equipment in medical aesthetics and clinical treatment. The coupler, as a key component for laser energy transmission and coupling, directly determines laser transmission efficiency, equipment operational accuracy, and lifespan through the cleanliness of its working environment and the stability of its internal gas pressure. During operation, the coupler relies on a clean gas path environment to ensure unobstructed laser light transmission and maintain stable internal pressure. Currently, the protection features of existing laser therapy device couplers suffer from the following shortcomings: 1. Insufficient cleanliness: The coupler lacks internal gas purification and closed-loop gas path control, allowing external dust and exhaust gases from equipment operation to intrude into the clean area, contaminating the laser transmission path and causing laser energy attenuation. 2. Insufficient pressure regulation: The coupler lacks automatic monitoring and adjustment of internal gas pressure. Pressure changes can cause cavity leakage and component deformation. The lack of intelligent exhaust control prevents the coupler from adapting to changes in actual gas conditions.

[0003] Therefore, it is necessary to design a laser therapy device coupler protection system to solve the problems existing in the current technology. Summary of the Invention

[0004] In view of this, the present invention proposes a coupler protection system for a laser therapy instrument, which aims to solve the problems of lack of gas purification and closed-loop gas path control inside the coupler, and the inability to intelligently control the exhaust gas, resulting in the coupler being unable to adapt and adjust according to changes in the actual gas.

[0005] This invention proposes a coupler protection system for a laser therapy device, comprising: Air filter; The first coupler is connected to one end of the air filter via a pipeline. The first coupler is configured as a clean room, with one end of the clean room connected to a gas inlet and the other end connected to a gas outlet. The second coupler is fixedly connected to the bottom of the first coupler at its top. The second coupler includes a monitoring cover and a monitoring base. The monitoring cover and the monitoring base cooperate with each other. The monitoring base is provided with a dark chamber. The side wall of the dark chamber is provided with an exhaust port. The front of the exhaust port is provided with a controller. The first solenoid valve, and the first coupler are connected to the first solenoid valve via a pipeline; An air pump, wherein the first solenoid valve is connected to the air pump via a pipeline; The second solenoid valve is provided with a first exhaust port. The air pump is connected to the second solenoid valve through a pipeline. A pressure reducing valve, wherein the second solenoid valve is connected to the pressure reducing valve via a pipeline, and the pressure reducing valve is provided with a second vent port; A one-way valve is disposed on the side wall of the first coupler and is in communication with the first coupler; The controller is electrically connected to the first solenoid valve, the second solenoid valve, the pressure reducing valve, the check valve, and the air pump. The controller controls the operation of the first solenoid valve, the second solenoid valve, the pressure reducing valve, the check valve, and the air pump, and controls the opening degree of the first exhaust port based on the first gas condition, and controls the opening and closing of the second exhaust port and the check valve based on the second gas condition.

[0006] Furthermore, the first solenoid valve is provided with a first air outlet, a first air inlet, and a second air inlet. The first air outlet is connected to the air pump via a pipeline, and the first air inlet is used to introduce air into the pipeline. The second air inlet is connected to the first coupler via a pipeline. The second solenoid valve is also provided with a second air outlet and a third air inlet. The third air inlet is connected to the air pump via a pipeline, and the second air outlet is connected to one end of the pressure reducing valve via a pipeline. The other end of the pressure reducing valve is connected to the air filter via a pipeline.

[0007] Furthermore, a laser light source is provided on the outer sidewall of the monitoring base, and a light source outlet that cooperates with the laser light source is provided on the inner sidewall of the monitoring base. The dark chamber is provided with a light trap and a light collecting mirror. The light collecting mirror is a plano-convex lens, and the light path emitted by the light collecting mirror and the laser light source is perpendicular.

[0008] Furthermore, the controller includes an acquisition and analysis unit, a first processing unit, a second processing unit, and a coupling protection unit; The acquisition and analysis unit is configured to acquire the gas pressure of the clean room. When the gas pressure is not within the gas pressure range, the second gas condition is determined based on the relative relationship between the gas pressure and the gas pressure range, and the opening and closing of the second exhaust port and the one-way valve are controlled based on the second gas condition. The first processing unit is configured to divide the darkroom into several gas data acquisition points, acquire the laser energy signal of the darkroom, and when the laser energy signal is greater than the laser energy signal threshold, construct a laser gas sequence from the gas data of the same type at each gas data acquisition point, and delete the gas data in each laser gas sequence based on the corresponding standard laser gas sequence to determine the laser influence sequence. The second processing unit is configured to determine the correlation results between each laser influence sequence and the laser energy signal based on the association rule algorithm, determine the first gas condition based on the number of the correlation results, control the opening of the first exhaust port based on the first gas condition, and determine whether to adjust the opening based on the change of the first gas condition. When adjustment is determined, the opening is adjusted based on the change of the first gas condition to determine the initial exhaust opening. The coupling protection unit is configured to determine the pass / fail status of the initial exhaust opening based on historical opening control. If the status is not pass / fail, an exhaust adjustment coefficient is determined based on the historical opening control, and the initial exhaust opening is adjusted based on the exhaust adjustment coefficient to determine the target exhaust opening. Exhaust protection is then performed based on the target exhaust opening.

[0009] Furthermore, when controlling the opening and closing of the second exhaust port and the one-way valve based on the second gas condition, the method includes: when the gas pressure is greater than the right boundary of the gas pressure range, the acquisition and analysis unit determines that the second gas condition is a pressure overflow, then controls the second exhaust port to open and closes the one-way valve until the gas pressure is within the gas pressure range; when the gas pressure is less than the left boundary of the gas pressure range, the acquisition and analysis unit determines that the second gas condition is a pressure deficiency, then controls the second exhaust port to close and opens the one-way valve until the gas pressure is within the gas pressure range.

[0010] Furthermore, in determining the first gas condition, the process includes: the second processing unit constructs a transaction database for each laser influence sequence and the laser energy signal based on the FP-Tree algorithm, calculates the support of all individual items and determines frequent 1-itemsets, determines the prefix path and node count of each item, extracts the conditional pattern base of each item in reverse order based on the frequent 1-itemsets, determines the corresponding conditional FP-Tree and constructs all frequent itemsets, determines the association result between the gas data and the laser energy signal in each laser influence sequence based on each frequent itemset, counts the number of association results and records it as the association number, and uses the association number as the first gas condition.

[0011] Furthermore, when controlling the opening degree of the first exhaust port, the following steps are included: the second processing unit sets a first association number and a second association number, wherein the first association number is greater than the second association number; when the association number is greater than or equal to the first association number, the opening degree of the first exhaust port is controlled to be a first opening degree; when the association number is less than the first association number but greater than the second association number, the opening degree of the first exhaust port is controlled to be a second opening degree; when the association number is less than or equal to the second association number, the opening degree of the first exhaust port is controlled to be a third opening degree, wherein 0 < third opening degree < second opening degree < first opening degree < 1.

[0012] Furthermore, when determining the initial exhaust opening, the process includes: the second processing unit determining the change in the number of historical related quantities within a unit time, and determining the average change in the number of historical related quantities; when the change in the number of related quantities within a unit time is less than or equal to the average change in the number of historical related quantities, it is determined that the opening of the first exhaust port will not be adjusted, and the opening is determined as the initial exhaust opening; when the change in the number of related quantities within a unit time is greater than the average change in the number of historical related quantities, it is determined that the opening of the first exhaust port will be adjusted, and a correlation deviation is determined based on the change in the number of related quantities and the average change in the number of historical related quantities; an exhaust adjustment index is determined based on the correlation deviation; and the initial exhaust opening is determined based on the exhaust adjustment index.

[0013] Furthermore, when determining the initial exhaust opening degree to be qualified, the following steps are taken: the coupling protection unit acquires all historical opening degree controls of the first exhaust port, analyzes each historical opening degree control, determines opening degree overflow, opening degree insufficiency, and standard opening degree. When there is no opening degree overflow or opening degree insufficiency, the initial exhaust opening degree is determined to be qualified, and the initial exhaust opening degree is determined as the target exhaust opening degree. When there is opening degree overflow or opening degree insufficiency, the initial exhaust opening degree is determined to be unqualified.

[0014] Furthermore, when determining the target exhaust opening, the process includes: counting the number of overflows and recording them as the overflow quantity, counting the number of insufficient openings and recording them as the insufficient quantity, and when the overflow quantity is greater than or equal to the insufficient quantity, determining the exhaust adjustment coefficient based on the overflow quantity, and when the overflow quantity is less than the insufficient quantity, determining the exhaust adjustment coefficient based on the insufficient quantity. The target exhaust opening is the product of the exhaust adjustment coefficient and the initial exhaust opening, and the target exhaust opening is at most 1.

[0015] Compared with existing technologies, the advantages of this invention are as follows: The air filter is connected to the first coupler via a pipeline, which purifies the gas entering the system, preventing external dust and exhaust gas from entering the cleanroom of the first coupler, maintaining the purity of the internal environment of the cleanroom, and avoiding contamination of the laser by pollutants, thereby ensuring the operational stability of the first coupler. The cleanroom of the first coupler, together with the gas inlet and outlet, forms a closed and circulating gas space, providing a stable clean gas path for the operation of the second coupler. The exhaust port on the side wall of the darkroom can discharge the exhaust gas generated during equipment operation, preventing the accumulation of exhaust gas in the area and affecting the stability of the second coupler. The controller realizes unified scheduling of all system components, solving the risk of independent operation and insufficient coordination between each gas path and execution component. The solenoid valve and pressure reducing valve realize the opening and closing of the gas path and pressure regulation, improving the reliability of protecting the first and second couplers, thereby realizing automatic regulation of internal gas pressure, avoiding abnormal pressure that could cause cavity leakage or component deformation, and ensuring the operational reliability of the laser therapy device.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] See Figure 1-3 As shown in some embodiments of this application, a laser therapy device coupler protection system includes: Air filter 6; The first coupler 7 and the air filter 6 are connected to one end of the first coupler 7 through a pipeline. The first coupler 7 is set up with a clean room 71. One end of the clean room 71 is connected to the gas inlet 72, and the other end of the clean room 71 is connected to the gas outlet 70. The second coupler 8 is fixedly connected to the bottom of the first coupler 7 at its top. The second coupler 8 includes a monitoring cover plate 80 and a monitoring base 81. The monitoring cover plate 80 and the monitoring base 81 cooperate with each other. The monitoring base 81 is provided with a dark chamber 82. The side wall of the dark chamber 82 is provided with an exhaust gas outlet 84. The front of the exhaust gas outlet 84 is provided with a controller 85. The first solenoid valve 1 and the first coupler 7 are connected to the first solenoid valve 1 through a pipeline; Air pump 2, and first solenoid valve 1 are connected to air pump 2 through pipeline; The second solenoid valve 3 is connected to the air pump 2 via a pipeline. The second solenoid valve 3 is provided with a first exhaust port 31. Pressure reducing valve 4 and second solenoid valve 3 are connected to pressure reducing valve 4 through pipelines. Pressure reducing valve 4 is provided with a second exhaust port 40. A one-way valve 5 is disposed on the side wall of the first coupler 7 and is connected to the first coupler 7; The controller 85 is electrically connected to the first solenoid valve 1, the second solenoid valve 3, the pressure reducing valve 4, the check valve 5 and the air pump 2. The controller 85 controls the operation of the first solenoid valve 1, the second solenoid valve 3, the pressure reducing valve 4, the check valve 5 and the air pump 2, and controls the opening degree of the first exhaust port 31 based on the first gas conditions, and controls the opening and closing of the second exhaust port 40 and the check valve 5 based on the second gas conditions.

[0022] Specifically, air filter 6 is the purification device for the entire system. Through the physical interception of its internal filter element, it gradually purifies the gas in the pipeline, removing impurities such as dust and metal particles. This prevents impurities from contaminating the laser transmission path and causing laser energy attenuation, while also preventing impurities from causing wear on other components. This ensures the purity of the gas entering the first coupler 7, thus providing a clean gas path environment for the laser. Since the function of each air filter 6 is consistent, the complete connection relationships of each air filter 6 will not be described individually. The first coupler 7, serving as a gas-protected transmission component, has a cleanroom 71 inside that provides a closed and independent clean space for the laser beam path. The cleanroom 71 is connected to a gas inlet 72 and a gas outlet 70 at its two ends. The gas inlet 72 allows clean gas, purified by the air filter 6, to be stably and continuously introduced into the cleanroom 71, creating a clean airflow and pressure environment within it. Based on the flow characteristics of the airflow, the gas in the cleanroom 71 flows out through the gas outlet 70, thus ensuring the cleanliness of the laser beam path and preventing risks such as decreased coupling efficiency and equipment malfunction due to beam path contamination. The second coupler 8 is fixedly installed at the bottom of the first coupler 7. The monitoring cover 80 and the monitoring base 81 cooperate to form a closed darkroom 82 structure. The darkroom 82 isolates external light from interfering with the internal monitoring process, ensuring the accuracy of the laser monitoring signal. The exhaust port 84 on the side wall of the dark chamber 82 is used to discharge the waste gas generated during the process inside the second coupler 8, preventing the waste gas from accumulating in the dark chamber 82 and affecting the accuracy of the laser. The controller 85 fixed at the front of the exhaust port 84 is the central hub of the entire protection system. It is responsible for receiving and processing various gas data and sending corresponding control commands to each component. The first solenoid valve 1 is installed on the pipeline between the first coupler 7 and the air pump 2. It interacts with the controller 85 through an electrical connection. The controller 85 can accurately control the on / off state of the first solenoid valve 1 according to the pressure of the first coupler 7 and the second coupler 8 to achieve start and stop control of the clean gas delivery. The air pump 2 is the power source of the system. It is connected to the first solenoid valve 1 through a pipeline. Under the command of the controller 85, it outputs a stable airflow to provide power for the delivery and circulation of clean gas and the pressure stability of the first coupler 7 and the second coupler 8, ensuring the fluidity of the gas. The second solenoid valve 3 is connected to the pipeline between the air pump 2 and the pressure reducing valve 4. The first exhaust port 31 on its side wall can adjust the opening degree under the control of the controller 85, so that the gas can be quickly discharged through the first exhaust port 31 to reduce the system pressure and avoid the risk of leakage of the cavity of the first coupler 7 and the second coupler 8 and deformation of components due to excessive pressure. At the same time, it can flexibly adjust the exhaust volume according to the gas demand under different working conditions to achieve dynamic control of the gas pressure.

[0023] Understandably, the pressure reducing valve 4 is connected to the second solenoid valve 3 via a pipeline. Its second exhaust port 40 can be opened under the control of the controller 85. Combined with the pressure reducing function of the pressure reducing valve 4, it further precisely regulates the gas pressure to ensure that the internal pressure of the coupler remains within a safe and stable operating range. The one-way valve 5 is located on the side wall of the first coupler 7 and communicates with the internal cavity of the first coupler 7. The one-way valve 5 allows external gas to enter the first coupler 7 and prevents gas backflow, thereby maintaining positive pressure in the cleanroom 71 and ensuring the stability of the laser. The controller 85 is electrically connected to the first solenoid valve 1, the second solenoid valve 3, the pressure reducing valve 4, the one-way valve 5, and the air pump 2. As the core control unit of the entire protection system, the controller 85 determines the first gas condition inside the second coupler 8 in real time, that is, the gas change situation, and analyzes and judges it through the control algorithm, thereby precisely controlling the opening degree of the first exhaust port 31 of the second solenoid valve 3 to achieve fine adjustment of the exhaust volume of the gas path. Furthermore, based on the second gas condition, that is, the air intake situation inside the first coupler 7, the controller precisely controls the opening and closing of the second exhaust port 40 of the pressure reducing valve 4 and the one-way valve 5, realizing adaptive regulation of the internal pressure of the first coupler 7. Through the coordinated cooperation of various components, a protection system integrating filtration, intelligent regulation, and exhaust gas purification is constructed, which comprehensively protects the clean environment and operational stability of the coupler, thereby improving the overall operational stability of the laser therapy device.

[0024] In some embodiments of this application, the first solenoid valve 1 is provided with a first air outlet 10, a first air inlet 12, and a second air inlet 11. The first air outlet 10 is connected to the air pump 2 through a pipeline, the first air inlet 12 is used to introduce air into the pipeline, and the second air inlet 11 is connected to the first coupler 7 through a pipeline. The second solenoid valve 3 is also provided with a second air outlet 32 ​​and a third air inlet 30. The third air inlet 30 is connected to the air pump 2 through a pipeline, and the second air outlet 32 ​​is connected to one end of the pressure reducing valve 4 through a pipeline. The other end of the pressure reducing valve 4 is connected to the air filter 6 through a pipeline.

[0025] Specifically, the first solenoid valve 1 is equipped with a first air outlet 10, a first air inlet 12, and a second air inlet 11. The first air inlet 12 is used to introduce air into the pipeline, directly providing air supply to the entire system and meeting the air supply requirements for system operation. The first air outlet 10 is connected to the air pump 2 through a pipeline. The air pump 2 provides a stable power source for the system, preventing gas delivery interruption and pressure imbalance due to insufficient power. The gas entering from the first air inlet 12 can flow into the air pump 2 from the first air outlet 10 and be delivered to the third air inlet 30 of the second solenoid valve 3. The second air outlet 32 ​​of the second solenoid valve 3 is connected to one end of the pressure reducing valve 4 through a pipeline. The gas flowing into the third air inlet 30 is delivered from the first air outlet 10 of the second solenoid valve 3. The air flows out from the second outlet 32 ​​and is delivered to the pressure reducing valve 4, preventing the airflow from directly impacting the first coupler 7 and causing pressure imbalance. The pressure reducing valve 4 provides a transitional guarantee for pressure stability. The other end of the pressure reducing valve 4 is connected to the air filter 6 through a pipeline. The airflow after being stabilized by the pressure reducing valve 4 is delivered to the air filter 6 for purification, thus forming an air source purification and pressure stabilization air path. This can not only continuously ensure the purity of the gas entering the first coupler 7 and prevent impurities from contaminating the internal environment of the first coupler 7 and the second coupler 8, but also continuously stabilize the air path pressure through the pressure reducing valve 4, avoiding pressure fluctuations that would affect the normal operation of the first coupler 7 and the second coupler 8, thus providing a stable and controllable air path operation basis for the laser therapy device.

[0026] In some embodiments of this application, a laser light source 83 is provided on the outer sidewall of the monitoring base 81, and a light source outlet 88 that cooperates with the laser light source 83 is provided on the inner sidewall of the monitoring base 81. The dark chamber 82 is provided with a light trap 86 and a light collecting mirror 87. The light collecting mirror 87 is a plano-convex lens, and the light paths emitted by the light collecting mirror 87 and the laser light source 83 are perpendicular.

[0027] Specifically, a laser source 83 is installed on the outer sidewall of the monitoring base 81. The laser source 83 is a low-power laser that continuously emits laser light into the dark chamber 82. The external sidewall design prevents the laser source 83 from occupying internal space in the dark chamber 82 and prevents heat generated during operation from interfering with the gas environment inside the dark chamber 82. Furthermore, external installation facilitates the maintenance of the laser source 83, ensuring a stable laser emission source for the system. The inner sidewall of the monitoring base 81 has a light source outlet 88 that precisely matches the laser source 83, guiding the emitted laser light into the dark chamber 82 without deviation, thus defining the laser's incident path and ensuring accurate entry into the dark chamber 82. The dark chamber 82 is equipped with an optical trap 86, which absorbs excess scattered laser light and ambient stray light within the dark chamber 82, preventing interference from repeated reflections of other light within the dark chamber 82. Darkroom 82 is equipped with a light-collecting mirror 87, which is a plano-convex lens. A plano-convex lens has the optical characteristics of one flat surface and one convex surface, enabling it to direct and converge the laser emitted by the laser source 83, gathering the dispersed laser beams into a concentrated beam and improving the laser energy collection efficiency. The light-collecting mirror 87 is installed perpendicular to the light path emitted by the laser source 83. At this position, the Rayleigh scattering intensity is maximum. The laser emitted by the laser source 83 undergoes Rayleigh scattering on the plane of the light-collecting mirror 87 and is emitted to the controller 85. The controller 85 can continuously collect the scattered laser energy signal on the light-collecting mirror 87, thereby sensing whether any abnormalities have occurred in the environment of darkroom 82, further ensuring the protection of the first coupler 7 and the second coupler 8.

[0028] The system works as follows: Air pump 2 is normally open. Under normal conditions, the first air inlet 12 and the first air outlet 10 of the first solenoid valve 1 are open, and the second air inlet 11 is closed. Air enters from the first air inlet 12 and flows out from the first air outlet 10. It then passes through air pump 2, the third air inlet 30 and the second air outlet 32 ​​of the second solenoid valve 3, the pressure reducing valve 4 and the air filter 6 in sequence until the gas flows into the gas inlet 72 of the first coupler 7. After passing through the clean room 71 and the gas inlet 72, it finally enters the dark room 82. When an abnormality occurs in the environment inside the dark chamber 82 (unstable laser energy signal), the controller 85 closes the first air inlet 12 and the first air outlet 10 of the first solenoid valve 1 and the second air outlet 32 ​​of the second solenoid valve 3 according to the abnormal situation, and opens the second air inlet 11 of the first solenoid valve 1 and the first exhaust outlet 31 of the second solenoid valve 3. The air pump 2 extracts the gas from the dark chamber 82. At the same time, the controller 85 controls the laser light source 83 to stop emitting laser. At this time, the gas extracted from the dark chamber 82 flows through the second air inlet 11 and the air pump 2, and finally flows out from the first exhaust outlet 31.

[0029] See Figure 4As shown, in some embodiments of this application, the controller 85 includes a data acquisition and analysis unit, a first processing unit, a second processing unit, and a coupling protection unit; The data acquisition and analysis unit is configured to acquire the gas pressure of the clean room 71. When the gas pressure is not within the gas pressure range, it determines the second gas condition based on the relative relationship between the gas pressure and the gas pressure range, and controls the opening and closing of the second exhaust port 40 and the one-way valve 5 based on the second gas condition. The first processing unit is configured to divide the dark chamber 82 into several gas data acquisition points, acquire the laser energy signal of the dark chamber 82, and when the laser energy signal is greater than the laser energy signal threshold, construct a laser gas sequence from the gas data of the same type at each gas data acquisition point, and delete the gas data in each laser gas sequence based on the corresponding standard laser gas sequence to determine the laser influence sequence. The second processing unit is configured to determine the correlation results of each laser influence sequence and laser energy signal based on the correlation rule algorithm, determine the first gas condition based on the number of correlation results, control the opening of the first exhaust port 31 based on the first gas condition, and determine whether to adjust the opening based on the change of the first gas condition. When adjustment is determined, the opening is adjusted based on the change of the first gas condition to determine the initial exhaust opening. The coupling protection unit is configured to determine the pass / fail status of the initial exhaust opening based on historical opening control. When the status is deemed unqualified, the exhaust adjustment coefficient is determined based on historical opening control, and the initial exhaust opening is adjusted based on the exhaust adjustment coefficient to determine the target exhaust opening. Exhaust protection is then performed based on the target exhaust opening.

[0030] Specifically, the data acquisition and analysis unit collects the gas pressure of the cleanroom 71 in real time. Through continuous data acquisition, the pressure dynamics of the cleanroom 71 can be monitored throughout the process, avoiding the risk of not being able to detect abnormal pressure in time. When the collected gas pressure is outside the preset gas pressure range, the data acquisition and analysis unit accurately determines and generates the corresponding second gas condition based on the specific relative relationship between the gas pressure and the gas pressure range. Then, according to the second gas condition, it controls the opening and closing of the second exhaust port 40 and the one-way valve 5, thereby quickly adjusting the pressure of the cleanroom 71 to a safe range. This avoids the risk of leakage of the first coupler 7 and the second coupler 8 cavity and deformation of components caused by large pressure changes, thus ensuring the pressure stability of the first coupler 7 and the second coupler 8. After the acquisition and analysis unit completes the opening and closing control of the second exhaust port 40 and the one-way valve 5, the first processing unit divides the dark chamber 82 into several gas data acquisition points. The specific number of points can be dynamically set according to the size of the dark chamber 82. In this embodiment, 20 points are preferred. Multi-point division can comprehensively cover the gas state of each area of ​​the dark chamber 82, eliminating the one-sidedness caused by single-point acquisition. At the same time, the laser energy signal of the dark chamber 82 is acquired in real time to determine whether the laser is affected by gas interference. When the laser energy signal is greater than the set laser energy signal threshold, it indicates that the laser has been affected by the gas in the dark chamber 82, that is, the environment in the dark chamber 82 has become abnormal. The first processing unit then integrates the gas data of the same type collected from each gas data acquisition point to construct a laser gas sequence. The gaseous data includes concentrations of oxygen, nitrogen, carbon dioxide, etc., and the laser gas sequence is a sequence composed of all gases containing concentrations of oxygen or nitrogen. The corresponding standard laser gas sequence is determined, which can be established through experimental simulation and verification of the laser source 83. There is a one-to-one correspondence between the standard gas data in the standard laser gas sequence and the gas data in the laser gas sequence. If there is a standard gas data in the standard laser gas sequence that is identical to the gas data in the laser gas sequence, it indicates that the gas data of that type at that gas data collection point conforms to the standard, and there is no gas anomaly. Therefore, the gas data in the laser gas sequence that corresponds to the standard gas data is deleted. This process determines the laser influence sequence, which includes all gas data with anomalies. The second processing unit uses an association rule algorithm to deeply analyze the intrinsic correlation between each laser influence sequence and the laser energy signal, thereby determining the correlation results. Based on the number of correlation results, a first gas condition is generated. The more correlation results there are, the more complex the overall gas anomaly, and the greater the impact on the laser.The opening of the first exhaust port 31 is controlled according to the first gas conditions, achieving precise matching between exhaust volume and the degree of gas influence. At the same time, based on the dynamic changes of the first gas conditions, it is determined whether the opening of the first exhaust port 31 needs to be adjusted. If it is determined that adjustment is needed, the opening is adapted and corrected based on the actual change of the first gas conditions to determine the initial exhaust opening. This ensures that the exhaust control can keep up with the real-time changes of the gas state and avoids protection failure caused by control lag.

[0031] Understandably, the coupling protection unit is responsible for retrieving historical opening control data, that is, all past actions that controlled the first exhaust port 31 of the second solenoid valve 3. Based on the historical opening control, the initial exhaust opening is judged to be qualified. By verifying the historical operating data, the risk of mismatch between the initial exhaust opening and the exhaust can be avoided. When the initial exhaust opening is judged to be unqualified, the exhaust adjustment coefficient is determined based on the pattern in the historical opening control. The exhaust adjustment coefficient is used to correct the initial exhaust opening, determine the target exhaust opening that is suitable for the actual working conditions, and perform exhaust protection according to the target exhaust opening. Through the guarantee of historical data calibration, the exhaust protection can fit the actual operating requirements of the first coupler 7 and the second coupler 8, avoid the risk of pressure runaway caused by improper opening settings, and thus comprehensively improve the stability and reliability of coupler protection.

[0032] In some embodiments of this application, when controlling the opening and closing of the second exhaust port 40 and the one-way valve 5 based on the second gas conditions, the following steps are taken: when the gas pressure is greater than the right boundary of the gas pressure range, the acquisition and analysis unit determines that the second gas condition is pressure overflow, then controls the second exhaust port 40 to open and closes the one-way valve 5 until the gas pressure is within the gas pressure range; when the gas pressure is less than the left boundary of the gas pressure range, the acquisition and analysis unit determines that the second gas condition is pressure deficiency, then controls the second exhaust port 40 to close and opens the one-way valve 5 until the gas pressure is within the gas pressure range.

[0033] Specifically, the data acquisition and analysis unit compares the collected gas pressure in cleanroom 71 with the gas pressure range. Based on this comparison, it determines the second gas condition and controls the opening and closing of the second exhaust port 40 and the one-way valve 5. The gas pressure range can be set according to the user manual of the laser light source 83, the factory report, etc. When the gas pressure in cleanroom 71 is detected to be greater than the right boundary of the gas pressure range, it is determined that the second gas condition is pressure overflow, that is, the positive pressure of cleanroom 71 exceeds the allowable range. Then, the second exhaust port 40 of the pressure reducing valve 4 is opened to quickly discharge the excess gas in cleanroom 71, thereby reducing the gas pressure inside cleanroom 71 and avoiding the risks of leakage of cleanroom 71 cavity, deformation of internal components, and damage to the sealing structure caused by continuous high pressure. At the same time, the one-way valve 5 is closed to prevent gas from continuing to enter cleanroom 71 until the gas pressure in cleanroom 71 drops back to the gas pressure range, so as to achieve precise pressure correction. When the gas pressure in cleanroom 71 is detected to be less than the left boundary of the gas pressure range, the second gas condition is determined to be insufficient pressure, that is, the gas pressure in cleanroom 71 is too low (i.e., negative pressure). Then, the second exhaust port 40 of the pressure reducing valve 4 is closed to block the external leakage channel of cleanroom 71 and prevent the gas pressure from dropping further. At the same time, the one-way valve 5 is controlled to open, thereby replenishing clean gas to cleanroom 71 to quickly raise the internal pressure until the gas pressure in cleanroom 71 rises back to the gas pressure range. The differentiated opening and closing control for the two abnormal states of pressure overflow and pressure insufficiency can keep the gas pressure in cleanroom 71 stable in a safe and suitable working range, eliminate the safety hazard of damage to the first coupler 7 and the second coupler 8 due to abnormal pressure, and improve the stability of the laser therapy device.

[0034] In some embodiments of this application, determining the first gas condition includes: a second processing unit constructing a transaction database for each laser influence sequence and laser energy signal based on the FP-Tree algorithm, calculating the support of all individual items and determining frequent 1-itemsets, determining the prefix path and node count of each item, extracting the conditional pattern base of each item in reverse order based on the frequent 1-itemsets, determining the corresponding conditional FP-Tree and constructing all frequent itemsets, determining the association result of gas data and laser energy signal in each laser influence sequence based on each frequent itemset, counting the number of association results and recording it as the association number, and using the association number as the first gas condition.

[0035] Specifically, a transaction database is constructed based on the FP-Tree for each laser influence sequence and laser energy signal. This means integrating the gas data in the laser influence sequence and the laser energy signal into a unified structured transaction data set. All individual support values ​​are statistically analyzed, and frequent 1-itemsets are determined. Individual support values ​​are used to quantify the frequency of occurrence of a single gas data item in the transaction database. By statistically analyzing individual support values, gas data items with higher occurrence frequencies can be filtered out, thereby determining frequent 1-itemsets. Prefix paths can clearly present the association hierarchy and positional relationship of each data item in the FP-Tree structure, while node counts accurately record the actual occurrence frequency of each data item, preventing the loss of data association relationships during algorithm processing and providing data support for the extraction of conditional pattern bases. Based on the conditional pattern base extracted from each item in reverse order of frequent 1-itemsets, the associated data subset corresponding to each frequent item is quickly located. The conditional pattern base can decompose the complex global association analysis into multiple independent local analyses, while ensuring the comprehensiveness and accuracy of association mining. The conditional FP-Tree is an association tree structure generated for local data, which can clearly present the strong association between local data. Based on the conditional FP-Tree, all frequent itemsets are constructed, which can comprehensively mine all data combinations with association between gas data and laser energy signals in the laser influence sequence. Based on each frequent itemset, the association results of gas data and laser energy signals in each laser influence sequence are determined, clarifying the corresponding association between changes in gas data and changes in laser energy signals. The number of associations is used as the first gas condition, which intuitively reflects the degree of influence of gas data on laser energy signals. The more associations, the more obvious the gas interference on the laser, thus ensuring the adaptability of gas regulation and the degree of laser influence, and further improving the reliability of protecting the first coupler 7 and the second coupler 8.

[0036] In some embodiments of this application, controlling the opening degree of the first exhaust port 31 includes: the second processing unit sets a first association number and a second association number, the first association number being greater than the second association number; when the association number is greater than or equal to the first association number, the opening degree of the first exhaust port 31 is controlled to be the first opening degree; when the association number is less than the first association number but greater than the second association number, the opening degree of the first exhaust port 31 is controlled to be the second opening degree; when the association number is less than or equal to the second association number, the opening degree of the first exhaust port 31 is controlled to be the third opening degree, wherein 0 < third opening degree < second opening degree < first opening degree < 1.

[0037] Specifically, when the number of detected correlations is greater than or equal to the first correlation number, it indicates that the gas interference level is the highest. The second processing unit then controls the opening of the first exhaust port 31 to the first opening, so as to quickly exhaust the abnormal gas in the dark chamber 82 with the maximum exhaust volume, thereby minimizing the gas interference on the first coupler 7 and the second coupler 8, and thus mitigating the risk of component damage caused by laser anomalies. When the number of associated connections is less than the first number of associated connections but greater than the second number of associated connections, it indicates a moderate level of gas interference. The second processing unit then controls the opening of the first exhaust port 31 to the second opening, using a moderate opening to exhaust abnormal gas in the dark chamber 82. This alleviates gas interference on the first coupler 7 and the second coupler 8, and avoids pressure imbalance in the dark chamber 82 due to excessive exhaust, thus balancing exhaust efficiency and gas path pressure stability. When the number of associated connections is less than or equal to the second number of associated connections, it indicates the lowest level of gas interference. Only a small amount of exhaust is needed to maintain gas stability. The second processing unit then controls the opening of the first exhaust port 31 to the third opening, which satisfies basic gas circulation and exhaust requirements while minimizing gas emissions. This maintains the stability of the internal pressure and clean gas environment of the dark chamber 82, allowing the opening of the first exhaust port 31 to be dynamically and precisely adjusted according to the degree of gas influence on the laser, further improving the reliability of protecting the first coupler 7 and the second coupler 8.

[0038] In some embodiments of this application, determining the initial exhaust opening includes: a second processing unit determining the change in the number of historical associated quantities within a unit time and determining the average change in the number of historical associated quantities; when the change in the number of associated quantities within a unit time is less than or equal to the average change in the number of historical associated quantities, it is determined that the opening of the first exhaust port 31 will not be adjusted, and the opening is determined as the initial exhaust opening; when the change in the number of associated quantities within a unit time is greater than the average change in the number of historical associated quantities, it is determined that the opening of the first exhaust port 31 will be adjusted, and an associated deviation is determined based on the change in the number of associated quantities and the average change in the number of historical associated quantities; an exhaust adjustment index is determined based on the associated deviation; and the initial exhaust opening is determined based on the exhaust adjustment index.

[0039] Specifically, by extracting the changes in the number of related quantities per unit time in historical data, we can fully understand the changes in the degree of influence of past gas data on laser energy signals and determine the average value of historical changes in related quantities. That is, by averaging all historical changes in related quantities per unit time, we can obtain a historical benchmark, thereby distinguishing between normal stable changes and sudden abnormal changes. When the change in the number of related quantities per unit time is less than or equal to the average value of historical changes in related quantities, it indicates that the current gas data anomaly is within the historical normal fluctuation range and no sudden or drastic abnormal changes have occurred. Therefore, we determine that the opening of the first exhaust port 31 should not be adjusted, and the current determined opening is set as the initial exhaust opening. This avoids pressure imbalance and gas circulation disorder in the anechoic chamber 82 caused by frequent adjustments to the opening of the first exhaust port 31 due to small fluctuations, thus ensuring the stability of system operation. When the change in the number of associated quantities detected per unit time is greater than the average change in the number of associated quantities in history, it indicates that the current gas data anomaly is a sudden and drastic change. If the opening is not adjusted in time, it will further aggravate the gas interference. Therefore, it is determined that the opening of the first exhaust port 31 should be adjusted. The correlation deviation is determined based on the difference between the change in the number of associated quantities and the average change in the number of associated quantities in history. The larger the correlation deviation, the more severe the sudden change in gas interference. The second processing unit sets a first correlation deviation and a second correlation deviation, and the first correlation deviation is greater than the second correlation deviation. When the correlation deviation is greater than or equal to the first correlation deviation, the exhaust adjustment index is determined as the first index. When the correlation deviation is less than the first correlation deviation but greater than the second correlation deviation, the exhaust adjustment index is determined as the second index. When the correlation deviation is less than or equal to the second correlation deviation, the exhaust adjustment index is determined as the third index. Wherein, 0 < third index < second index < first index < 1. The initial exhaust opening is the product of the current opening of the first exhaust port 31 and the exhaust adjustment index, and the maximum initial exhaust opening is 1. The initial exhaust opening is determined based on the exhaust adjustment index, which enables the first exhaust port 31 to dynamically and accurately adapt and correct itself in response to real-time abnormal changes in gas interference. This not only allows for a rapid response to and mitigation of interference caused by abnormal gas, but also ensures the accuracy of the opening adjustment, thereby improving the reliability of protecting the first coupler 7 and the second coupler 8.

[0040] In some embodiments of this application, when determining the initial exhaust opening degree, the following steps are included: the coupling protection unit acquires all historical opening degree controls of the first exhaust port 31, analyzes each historical opening degree control, determines opening degree overflow, opening degree insufficiency, and standard opening degree. When there is no opening degree overflow or opening degree insufficiency, the initial exhaust opening degree is determined to be qualified, and the initial exhaust opening degree is determined as the target exhaust opening degree. When there is opening degree overflow or opening degree insufficiency, the initial exhaust opening degree is determined to be unqualified.

[0041] Specifically, a comprehensive review of the opening control records of the first exhaust port 31 under all past operating conditions was conducted to fully reconstruct the opening changes and control effects of the first exhaust port 31 during historical operation, providing a comprehensive and authentic historical reference for verifying the rationality of the opening. In-depth analysis of all historical opening control data was performed, distinguishing between three states that occurred during historical operation: opening overflow, insufficient opening, and standard opening. Opening overflow refers to an abnormal opening state caused by excessive opening setting, resulting in excessive exhaust and a rapid drop in pressure in the anechoic chamber 82. Insufficient opening refers to an abnormal opening state caused by insufficient opening setting, resulting in inadequate exhaust and the inability to timely discharge abnormal gases. Standard opening refers to an opening state that effectively completes exhaust protection and maintains stable pressure in the anechoic chamber 82. If the control state of the first exhaust port 31 does not exhibit either opening overflow or insufficient opening abnormalities, it indicates that the initial exhaust opening fully matches the requirements of historical stable operation and will not... The system will not cause pressure imbalance due to excessive exhaust, nor will it cause protection failure due to insufficient exhaust. The coupling protection unit will determine that the initial exhaust opening is qualified and directly set the initial exhaust opening as the target exhaust opening. If there is any abnormal state of opening overflow or insufficient opening, it indicates that the first exhaust port 31 has not met the requirements for safe and stable operation in the past. If the initial exhaust opening is used directly, it will cause risks such as exhaust abnormality, aggravated gas interference, and damage to the coupler operation. Therefore, the coupling protection unit will determine that the initial exhaust opening is unqualified. Through data-driven compliance verification, the defects of the initial exhaust opening can be avoided, and the reliability of protecting the first coupler 7 and the second coupler 8 can be improved.

[0042] In some embodiments of this application, determining the target exhaust opening includes: counting the number of overflows and recording them as the overflow quantity; counting the number of insufficient openings and recording them as the insufficient quantity; when the overflow quantity is greater than or equal to the insufficient quantity, then determining the exhaust adjustment coefficient based on the overflow quantity; when the overflow quantity is less than the insufficient quantity, then determining the exhaust adjustment coefficient based on the insufficient quantity; the target exhaust opening is the product of the exhaust adjustment coefficient and the initial exhaust opening, and the target exhaust opening is at most 1.

[0043] Specifically, when determining the exhaust adjustment coefficient based on the amount of overflow, it indicates that the problem of opening overflow was more frequent and severe in historical operation. Therefore, two values ​​for the amount of overflow are set, and the exhaust adjustment coefficient is determined according to the interval division. When the amount of overflow is greater, it indicates that the opening of the first exhaust port 31 has been set too large more often in the past, so the exhaust adjustment coefficient is correspondingly smaller, thereby reducing the opening of the first exhaust port 31. The range of the exhaust adjustment coefficient is 0-1, in order to reduce the situation where the opening of the first exhaust port 31 does not match the exhaust situation. When determining the exhaust adjustment coefficient based on the amount of deficiency, it indicates that the problem of insufficient opening was more frequent and severe in historical operation. Similarly, two values ​​are set for the amount of overflow. Two values ​​are used to determine the exhaust adjustment coefficient based on the interval division. The more insufficient the quantity, the more times the opening of the first exhaust port 31 has been set too small in the past, and the larger the exhaust adjustment coefficient will be. The range of the exhaust adjustment coefficient is 1-1.5, which increases the opening of the first exhaust port 31 accordingly, further reducing the situation where the opening of the first exhaust port 31 does not match the exhaust situation. The final determined target exhaust opening is the product of the exhaust adjustment coefficient and the initial exhaust opening. At the same time, the maximum target exhaust opening is 1. By quantitative statistics and targeted determination of the exhaust adjustment coefficient, the reliability of protecting the first coupler 7 and the second coupler 8 is improved.

[0044] In summary, the beneficial effects of this invention are as follows: The air filter is connected to the first coupler via a pipeline, which purifies the gas entering the system, preventing external dust and exhaust gas from entering the cleanroom of the first coupler, maintaining the purity of the internal environment of the cleanroom, and avoiding contamination of the laser by pollutants, thereby ensuring the operational stability of the first coupler. The cleanroom of the first coupler, together with the gas inlet and outlet, forms a closed and circulating gas space, providing a stable clean gas path for the operation of the second coupler. The exhaust port on the side wall of the darkroom can discharge the exhaust gas generated during equipment operation, preventing the accumulation of exhaust gas in the area and affecting the stability of the second coupler. The controller realizes unified scheduling of all system components, solving the risk of independent operation and insufficient coordination between each gas path and execution component. The solenoid valve and pressure reducing valve realize the opening and closing of the gas path and pressure regulation, improving the reliability of protecting the first and second couplers, thereby realizing automatic regulation of internal gas pressure, avoiding abnormal pressure that could cause cavity leakage or component deformation, and ensuring the operational reliability of the laser therapy device.
