Description

Technical Field

[0001] This application relates to the field of traditional Chinese medicine fumigation and inhalation technology, and more specifically, to a traditional Chinese medicine fumigation and inhalation system and method for use in the field of rheumatology and immunology. Background Technology

[0002] Rheumatic and immune diseases (such as rheumatoid arthritis and ankylosing spondylitis) are common chronic inflammatory diseases in clinical practice. Traditional Chinese medicine fumigation inhalation therapy can directly penetrate the effective components of Chinese medicine to the lesion site through atomized medicinal mist, and has the effects of anti-inflammatory and analgesic, and improving local microcirculation. It has become an important adjunctive treatment for these diseases. In fumigation therapy, the temperature of the compound Chinese medicine mist is the core factor determining the therapeutic effect and safety. Too high a temperature will destroy the activity of the volatile effective components of Chinese medicine (such as menthol and volatile oil of chuanxiong), reducing the efficacy. Too low a temperature will weaken the penetration ability of the mist and may also cause skin irritation and discomfort to patients. Therefore, precise control of the mist temperature is a key requirement for the practical application of traditional Chinese medicine fumigation technology.

[0003] Existing temperature control solutions for traditional Chinese medicine fumigation and inhalation equipment mostly rely on manual experience to set target temperatures, or simply use a single-stage heating module (such as a common resistance heater) combined with a basic proportional-integral-differential algorithm to achieve simple temperature control. These technologies have significant drawbacks: First, manual setting has large errors, making it impossible to dynamically match the optimal temperature for different diseases and compound prescriptions, easily leading to wasted efficacy. Second, single-stage temperature control cannot offset heat loss and environmental interference, causing the actual temperature of the mist to deviate from the target value. Third, it is not adapted to the thermosensitive characteristics and complex heat exchange flow patterns of traditional Chinese medicine compound prescriptions, easily causing inactivation of effective components or fluctuations in mist temperature, and even posing a risk of skin burns. Therefore, how to achieve multi-stage synergistic temperature control of traditional Chinese medicine compound mists based on the specificity of different rheumatic and immune diseases has become a challenge for the industry. Summary of the Invention

[0004] This application provides a traditional Chinese medicine fumigation inhalation system and method for rheumatology and immunology, which can perform multi-level synergistic temperature control of the traditional Chinese medicine compound mist based on the specificity of matching traditional Chinese medicine compound with different rheumatic and immunological diseases.

[0005] In a first aspect, this application provides an intelligent temperature control method for a traditional Chinese medicine fumigation inhaler used in rheumatology and immunology, for intelligently controlling the temperature of a compound traditional Chinese medicine mist matched to the target user's disease type in the traditional Chinese medicine fumigation inhalation system. The method includes: The target temperature of the herbal compound medicine after it is atomized by the fumigation inhaler is set according to the type of rheumatic and immune diseases of the target users. Determine the target heat exchange temperature of the heat exchange medium in the heating area of ​​the fumigation inhaler, and adaptively adjust the heating power based on the target heat exchange temperature and the temperature feedback signal of the heat exchange medium in the heating area to obtain a constant temperature heat exchange medium after temperature adjustment. The constant temperature heat exchange medium is pumped into the heat exchange channel of the heat exchange area of ​​the fumigation inhaler, and the temperature sequence of the atomized Chinese herbal compound mist at the outlet of the heat exchange area is obtained. Based on the target mist temperature and the temperature time sequence, the temperature difference gradient of the traditional Chinese medicine compound mist in the heat exchange zone is determined. Then, fuzzy reasoning is performed on the temperature difference gradient and the thermal stability state of the constant temperature heat exchange medium to obtain the adaptive compensation factor for the heat exchange efficiency of the traditional Chinese medicine compound mist in the counter-current-cross-current composite heat exchange mode. The rotational speed of the circulating pump in the fumigation inhaler is controlled according to the adaptive compensation factor to adjust the heat exchange intensity between the herbal compound mist and the heat exchange medium.

[0006] In some embodiments, setting the target atomization temperature of the traditional Chinese medicine compound solution after it has been atomized by the fumigation inhaler according to the target user's rheumatic immune disease type specifically includes: Obtain historical clinical treatment data for various rheumatic and immune diseases; A temperature parameter matrix was established based on the historical clinical treatment data to determine the types of rheumatic and immune diseases, appropriate traditional Chinese medicine formulas, and fumigation temperatures. Based on the temperature parameter matrix, the target user's rheumatic immune disease type, and the appropriate traditional Chinese medicine compound, the target mist temperature is set after the traditional Chinese medicine compound is atomized by the fumigation inhaler.

[0007] In some embodiments, determining the target heat exchange temperature of the heat exchange medium within the heating zone of the fumigation inhaler specifically includes: Determine the heat loss coefficient from the heating zone to the heat exchange zone of the fumigation inhaler; The initial heat exchange temperature of the heat exchange medium is determined based on the target atomization temperature of the traditional Chinese medicine compound liquid and the heat loss coefficient. The initial heat exchange temperature is adjusted for environmental conditions to obtain the environmentally corrected heat exchange temperature. The environmental heat exchange temperature is further corrected based on the thermosensitive properties of the traditional Chinese medicine compound liquid to obtain the target heat exchange temperature of the heat exchange medium in the heating area of ​​the fumigation inhaler.

[0008] In some embodiments, the heating power is adaptively adjusted based on the target heat exchange temperature and the temperature feedback signal of the heat exchange medium in the heating region to obtain a temperature-adjusted isothermal heat exchange medium, specifically including: Acquire the temperature feedback signal of the heat exchange medium in the heating zone; The real-time temperature difference and temperature difference rate of the heat exchange medium in the heating zone are determined by the target heat exchange temperature and the temperature feedback signal. The heating power of the heating zone is adjusted based on the real-time temperature difference and the rate of change of temperature difference to obtain a constant-temperature heat exchange medium after temperature adjustment.

[0009] In some embodiments, determining the temperature difference gradient of the traditional Chinese medicine compound mist in the heat exchange zone based on the target mist temperature and the temperature time sequence specifically includes: The instantaneous temperature deviation between the actual temperature of the traditional Chinese medicine compound mist and the target mist temperature in the heat exchange area is determined based on the temperature time sequence. The instantaneous gradient sequence of the traditional Chinese medicine compound mist in the heat exchange zone is determined based on the instantaneous temperature deviation. Based on the atomization amount of the medicinal mist in the heat exchange zone and the volatilization coefficient of the traditional Chinese medicine compound medicinal mist, a composite compensation coefficient for the atomization and volatilization of the traditional Chinese medicine compound medicinal mist is generated. The instantaneous gradient sequence is dynamically compensated by the composite compensation coefficient to obtain the temperature difference gradient of the traditional Chinese medicine compound mist in the heat exchange region.

[0010] In some embodiments, fuzzy reasoning is performed on the temperature difference gradient and the thermal stability state of the isothermal heat exchange medium to obtain an adaptive compensation factor for the heat exchange efficiency of the traditional Chinese medicine compound mist in the counter-current-cross-current composite heat exchange mode. Specifically, this includes: Determine the thermal stability state of the isothermal heat exchange medium; By performing dual-input fuzzy reasoning on the temperature difference gradient and the thermal stability state, the initial heat transfer compensation coefficient of the traditional Chinese medicine compound mist in the heat transfer region is obtained. Based on the counter-flow-crossflow composite heat transfer mode, a composite flow pattern correction factor is introduced to correct the flow pattern of the initial heat transfer compensation coefficient, thereby obtaining the flow pattern adaptation compensation coefficient. Based on the viscosity grade of the traditional Chinese medicine compound liquid, the heat transfer hysteresis compensation coefficient of the flow pattern adaptation is performed to obtain the adaptive compensation factor of the heat transfer efficiency of the traditional Chinese medicine compound mist in the counter-current-cross-current composite heat transfer mode.

[0011] In some embodiments, controlling the rotational speed of the circulating pump in the fumigation inhaler according to the adaptive compensation factor to adjust the heat exchange intensity between the traditional Chinese medicine compound mist and the heat exchange medium specifically includes: The target speed command for controlling the circulating pump in the fumigation inhaler is generated based on the linear correspondence between the adaptive compensation factor and the target speed of the circulating pump. The target speed command is converted into a control signal to adjust the speed of the circulating pump through a brushless motor driver, thereby changing the flow rate of the heat exchange medium in the heat exchange channel to adjust the heat exchange intensity between the traditional Chinese medicine compound mist and the heat exchange medium.

[0012] Secondly, this application provides a traditional Chinese medicine fumigation and inhalation system for rheumatology and immunology, the system including an intelligent temperature control unit, the intelligent temperature control unit comprising: The data acquisition module is used to set the target mist temperature of the traditional Chinese medicine compound after it is atomized by the fumigation inhaler, based on the type of rheumatic immune disease of the target user. The processing module is used to determine the target heat exchange temperature of the heat exchange medium in the heating area of ​​the fumigation inhaler, and to adaptively adjust the heating power based on the target heat exchange temperature and the temperature feedback signal of the heat exchange medium in the heating area to obtain a constant temperature heat exchange medium after temperature adjustment. The processing module is used to pump the constant temperature heat exchange medium into the heat exchange channel of the heat exchange area of ​​the fumigation inhaler, and to obtain the temperature sequence of the atomized Chinese medicine compound mist at the outlet of the heat exchange area. The processing module is used to determine the temperature difference gradient of the traditional Chinese medicine compound mist in the heat exchange region based on the target mist temperature and the temperature time sequence, and then perform fuzzy reasoning on the temperature difference gradient and the thermal stability state of the constant temperature heat exchange medium to obtain an adaptive compensation factor for the heat exchange efficiency of the traditional Chinese medicine compound mist in the counter-current-cross-current composite heat exchange mode. The execution module is used to control the rotation speed of the circulating pump in the fumigation inhaler according to the adaptive compensation factor to adjust the heat exchange intensity between the traditional Chinese medicine compound mist and the heat exchange medium.

[0013] Thirdly, this application provides a computer device, the computer device including a memory and a processor, the memory storing code, the processor being configured to acquire the code and execute the above-described intelligent temperature control method for a traditional Chinese medicine fumigation inhaler for rheumatology and immunology.

[0014] Fourthly, this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-mentioned intelligent temperature control method for a traditional Chinese medicine fumigation inhaler for rheumatology and immunology.

[0015] The technical solutions provided by the embodiments disclosed in this application have the following beneficial effects: The traditional Chinese medicine fumigation and inhalation system and method for rheumatology and immunology provided in this application firstly sets the target atomization temperature of the traditional Chinese medicine compound solution after it is atomized by the fumigation inhaler, based on the target user's rheumatic and immunological disease type; then, it determines the target heat exchange temperature of the heat exchange medium in the heating area of ​​the fumigation inhaler, and adaptively adjusts the heating power based on the target heat exchange temperature and the temperature feedback signal of the heat exchange medium in the heating area to obtain a constant-temperature heat exchange medium; finally, it pumps the constant-temperature heat exchange medium into the heat exchange channel of the heat exchange area of ​​the fumigation inhaler, and... The temperature time series of the atomized traditional Chinese medicine compound mist at the outlet of the heat exchange zone is obtained; the temperature difference gradient of the traditional Chinese medicine compound mist in the heat exchange zone is determined according to the target mist temperature and the temperature time series, and then fuzzy reasoning is performed on the temperature difference gradient and the thermal stability state of the isothermal heat exchange medium to obtain an adaptive compensation factor for the heat exchange efficiency of the traditional Chinese medicine compound mist in the counter-current-cross-current composite heat exchange mode; the speed of the circulating pump in the fumigation inhaler is controlled according to the adaptive compensation factor to adjust the heat exchange intensity between the traditional Chinese medicine compound mist and the heat exchange medium.

[0016] Therefore, this application controls the rotation speed of the circulating pump in the fumigation inhaler based on the aforementioned adaptive compensation factor to adjust the heat exchange intensity between the herbal compound mist and the heat exchange medium. First, it determines that the constant-temperature heat exchange medium can achieve a stable temperature within 0.2℃ above and below the target heat exchange temperature. The determination of the constant-temperature heat exchange medium can be achieved through multi-dimensional precise control, determining the target heat exchange temperature after multiple corrections including heat loss coefficient compensation, environmental correction, and the thermosensitive characteristics of the herbal medicine. Then, through adaptive adjustment, the temperature of the constant-temperature heat exchange medium is stabilized within 0.2℃ above and below the target heat exchange temperature, providing sufficient heat for the heat exchange area. A stable heat source with zero baseline deviation prevents the temperature of the atomized herbal compound from deviating from the target value due to fluctuations in the medium temperature, ensuring the therapeutic effect of fumigation and inhalation. Then, by determining the temperature difference gradient, an instantaneous gradient sequence reflecting the dynamic changes in the herbal mist temperature deviation within the heat exchange zone can be obtained. Determining the temperature difference gradient provides a precise basis for power adjustment in the heat exchange zone, ensuring that the herbal mist temperature rapidly and stably approaches the target value, improving the accuracy and stability of fumigation herbal mist temperature control. By capturing the dynamic trend of temperature deviation in real time, the risk of deviation expansion can be identified in advance, providing a basis for adjusting the heat exchange intensity. This provides predictive evidence, thoroughly resolving the core issue of temperature overshoot caused by temperature lag in the prior art. Finally, by determining the adaptive compensation factor, the final coefficient for quantifying the heat exchange regulation requirements in the heat exchange region after flow pattern correction and viscosity lag compensation of the traditional Chinese medicine compound is obtained. The determination of the adaptive compensation factor upgrades the regulation basis from a single static feedback to a dual-dimensional prediction of dynamic trends and medium state through the collaborative sensing of multiple operating parameters. Combined with multiple corrections of composite flow patterns and liquid characteristics, this addresses the lack of coordinated multi-operating parameters and incompatibility with composite heat exchange in existing technologies from the core logic layer of temperature regulation in the heat exchange region. The lack of consideration for differences in the properties of the medicinal liquid leads to inaccurate heating efficiency adjustment, resulting in large temperature deviations in the medicinal mist, loss of the active ingredients in traditional Chinese medicine, and reduced therapeutic effects. To address this, the temperature of the traditional Chinese medicine compound medicinal mist should be dynamically adapted to the state of the heat exchange medium, differences in flow patterns, and changes in the medicinal liquid properties. This allows for real-time response to the influence of multiple variables such as fluctuations in thermal stability, differences in flow patterns, and changes in medicinal liquid viscosity, precisely matching the heat exchange adjustment requirements to ensure stable and compliant temperature control of the traditional Chinese medicine compound medicinal mist. In summary, based on the above solution, multi-level synergistic temperature control of the traditional Chinese medicine compound medicinal mist can be implemented based on the specificity of different rheumatic and immune diseases.

Detailed Implementation

[0018] To better understand the technical solution of this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] refer to Figure 1 The figure is an exemplary flowchart of an intelligent temperature control method for a traditional Chinese medicine fumigation inhaler for rheumatology and immunology, according to some embodiments of this application. The intelligent temperature control method for the traditional Chinese medicine fumigation inhaler for rheumatology and immunology mainly includes the following steps: In step 101, the target mist temperature of the traditional Chinese medicine compound solution after it is atomized by the fumigation inhaler is set according to the type of rheumatic immune disease of the target user.

[0020] In some embodiments, setting the target atomization temperature of the traditional Chinese medicine compound solution after it has been atomized by the fumigation inhaler, based on the target user's rheumatic immune disease type, can be achieved through the following steps: Obtain historical clinical treatment data for various rheumatic and immune diseases; A temperature parameter matrix was established based on the historical clinical treatment data to determine the types of rheumatic and immune diseases, appropriate traditional Chinese medicine formulas, and fumigation temperatures. Based on the temperature parameter matrix, the target user's rheumatic immune disease type, and the appropriate traditional Chinese medicine compound, the target mist temperature is set after the traditional Chinese medicine compound is atomized by the fumigation inhaler.

[0021] It should be noted that, in this application, the historical clinical treatment data is structured historical case data covering various types of rheumatic and immune diseases, appropriate traditional Chinese medicine (TCM) formulas, disease stages, fumigation mist temperature, skin tolerance temperature, volatile concentration of effective TCM components, and treatment effect scores. This historical clinical treatment data is the core foundational data for constructing the temperature parameter matrix, providing real clinical evidence for the matrix and ensuring that the correlation between disease, formula, and temperature in the matrix meets actual treatment needs, avoiding a disconnect between theoretical settings and clinical practice, and guaranteeing treatment efficacy and safety. In specific implementation, obtaining historical clinical treatment data for various rheumatic and immune diseases can be achieved in the following way: multiple (e.g., 500) complete case data can be extracted through the structured data interface of the hospital's electronic medical record system, including: patient basic information, rheumatic and immune disease type, TCM formula, fumigation mist temperature parameters, measured skin tolerance temperature, detected volatile concentration of effective TCM components, and treatment effect scores. Then, all extracted case data are preprocessed using existing statistical software (e.g., social science statistical software packages), and the output structured dataset is used as historical clinical treatment data for various rheumatic and immune diseases.

[0022] In specific implementation, the temperature parameter matrix for rheumatic immune disease type, appropriate traditional Chinese medicine compound, and fumigation temperature based on the historical clinical treatment data can be established in the following way: Partial least squares regression algorithm can be used to fit the correlation between rheumatic immune disease type, appropriate traditional Chinese medicine compound, disease stage, and fumigation mist temperature in the historical clinical treatment data, constructing a four-dimensional correlation matrix of rheumatic immune disease type - traditional Chinese medicine compound type - disease stage - target mist temperature. This four-dimensional correlation matrix is ​​then used as the temperature parameter matrix for rheumatic immune disease type, appropriate traditional Chinese medicine compound, and fumigation temperature. Specifically, the input historical clinical treatment data can be modeled using the partial least squares regression module of statistical software. The cross-validation fold can be set to 5, and the regression coefficients can be iteratively optimized until the model prediction error is less than or equal to ±0.3℃. After fitting, the encoded values ​​of rheumatic immune disease type, appropriate traditional Chinese medicine compound, and disease stage are associated with the corresponding optimal mist temperature according to the matrix structure, forming a four-dimensional correlation matrix of rheumatic immune disease type - traditional Chinese medicine compound type - disease stage - target mist temperature.

[0023] It should be noted that in this application, the temperature parameter matrix is ​​a multi-dimensional correlation matrix that characterizes the precise correspondence between the type of rheumatic immune disease, the type of suitable traditional Chinese medicine compound, the disease stage, and the target drug mist temperature. This temperature parameter matrix can automatically match the optimal drug mist temperature according to the patient's disease information, realize the precise automatic setting of the target drug mist temperature, and avoid the error of manual experience setting. At the same time, dynamically matching the drug mist temperature for different disease types, compound prescriptions, and disease stages can improve the retention rate of the active ingredients of traditional Chinese medicine and the therapeutic effect.

[0024] In specific implementation, the target mist temperature after the traditional Chinese medicine compound solution is atomized by the fumigation inhaler can be set based on the temperature parameter matrix, the target user's rheumatic immune disease type, and the appropriate traditional Chinese medicine compound. This can be achieved in the following way: the target user's input of rheumatic immune disease type (e.g., acute phase of rheumatoid arthritis, remission phase of ankylosing spondylitis), appropriate traditional Chinese medicine compound (e.g., wind-dispelling and dampness-removing compound, blood-activating and collaterals-dredging compound), and disease stage can be obtained through a human-computer interaction interface with a touch screen and physical buttons. Based on the rheumatic immune disease type, the appropriate traditional Chinese medicine compound type, and the disease stage, the corresponding target mist temperature is automatically retrieved from the temperature parameter matrix. If the target user does not specify a traditional Chinese medicine compound, the clinically commonly used optimal traditional Chinese medicine compound and the corresponding target mist temperature can be automatically matched based on the rheumatic immune disease type. If the target user has a rare type of rheumatic immune disease... If the disease type does not match in the matrix, the system automatically outputs a safe target mist temperature range of 38.5-39.5℃. Simultaneously, a pop-up window on the human-machine interface prompts the target user for confirmation and provides manual adjustment permissions of ±1℃. The target mist temperature is determined based on the target user's rheumatic immune disease type, the appropriate traditional Chinese medicine compound, and the disease stage. This temperature value ensures that the atomized traditional Chinese medicine compound mist retains the activity of its effective components to achieve the best therapeutic effect. This target mist temperature accurately matches the characteristics of the rheumatic immune disease and the compound, maximizing the utilization rate of the effective components of the traditional Chinese medicine and directly improving the fumigation treatment effect. It also avoids the problem of reduced efficacy due to excessively high or low temperatures. It can serve as the core benchmark for subsequent temperature adjustment processes in the heating and heat exchange areas, ensuring a clear direction for mist temperature adjustment and maintaining the stability and controllability of the equipment's temperature control logic.

[0025] In step 102, the target heat exchange temperature of the heat exchange medium in the heating area of ​​the fumigation inhaler is determined. The heating power is adaptively adjusted based on the target heat exchange temperature and the temperature feedback signal of the heat exchange medium in the heating area to obtain a constant temperature heat exchange medium after temperature adjustment.

[0026] In some embodiments, reference Figure 2 The figure is a flowchart illustrating the operation of determining the target heat exchange temperature according to some embodiments of this application. The determination of the target heat exchange temperature of the heat exchange medium within the heating area of ​​the fumigation inhaler in this application can be achieved using the following steps: Determine the heat loss coefficient from the heating zone to the heat exchange zone of the fumigation inhaler; The initial heat exchange temperature of the heat exchange medium is determined based on the target atomization temperature of the traditional Chinese medicine compound liquid and the heat loss coefficient. The initial heat exchange temperature is adjusted for environmental conditions to obtain the environmentally corrected heat exchange temperature. The environmental heat exchange temperature is further corrected based on the thermosensitive properties of the traditional Chinese medicine compound liquid to obtain the target heat exchange temperature of the heat exchange medium in the heating area of ​​the fumigation inhaler.

[0027] It should be noted that, in this application, the heating zone is the core area in the fumigation inhaler that initially heats the heat exchange medium. It incorporates a positive temperature coefficient heater and a temperature sensor. This heating zone serves as the preheating center for the heat exchange medium, rapidly heating it to near the target range, providing the initial heat source for subsequent heat exchange in the heat exchange zone. This lays the foundation for precise temperature control in the heat exchange zone, preventing the atomized drug mist temperature from failing to meet standards due to excessively low initial temperature. The heat exchange zone is crucial for achieving constant temperature heat exchange between the heat exchange medium and the atomized drug mist in the fumigation inhaler. This is a dedicated area for heat exchange in traditional Chinese medicine compound mist. It features a counter-current / cross-flow composite heat exchange channel composed of an inner small heat exchange tube, an outer large heat exchange tube, and a short, straight mist delivery tube. The inner small heat exchange tube has a diameter of 8-10mm, and the outer large heat exchange tube has a diameter of 20-25mm, both responsible for the flow of the heat exchange medium. The short, straight mist delivery tube, 15-20cm long and 8-10mm in diameter, is responsible for delivering the mist. It is made of medical-grade 316L stainless steel, and silicone seals are installed at both ends of the heat exchange channel. The inlet connects to the heating area and the mist delivery pipeline to ensure no media leakage and provide space for precise adjustment of the mist temperature. The short, straight mist delivery pipe design follows the principles of short path and low turbulence, reducing mist residence time and preventing mist particle aggregation or wall adsorption. This ensures that the mist particle size is maintained within the effective delivery range of 1-5μm. At the same time, the combined counter-current and cross-current flow method avoids local overheating or uneven temperature of the mist, ensuring that the mist temperature is stable and close to the target value. Furthermore, the herbal compound mist does not directly contact the heat exchange medium, which can retain the activity of the effective components of the herbal medicine and avoid contamination by the heat exchange medium. The heat exchange medium is a carrier that circulates and transfers heat between the heating area and the heat exchange area of ​​the fumigation inhaler. Water or medical silicone oil is commonly used. It has stable specific heat capacity and heat transfer performance. With its stable thermophysical properties, the heat exchange medium can efficiently transfer heat from the heating area to the heat exchange area, avoiding uneven heat transfer. Different heating media can be matched according to different herbal compound requirements to improve the applicability of the equipment. For example, silicone oil is suitable for high-temperature requirements.

[0028] In specific implementation, the heat loss coefficient from the heating zone to the heat exchange zone of the fumigation inhaler can be determined in the following way: Five sets of heat exchange medium temperature data under steady-state conditions can be continuously collected by temperature sensors installed symmetrically at the outlet pipe of the heating zone and the inlet pipe of the heat exchange zone at a sampling frequency of 2kHz. The heat loss temperature difference of each set of heat exchange medium temperature data, i.e., the difference between the outlet temperature of the heating zone and the inlet temperature of the heat exchange zone, is calculated. Then, the average value of the heat loss temperature difference of all heat exchange medium temperature data is divided by the average value of the outlet temperature of the heating zone to obtain the heat loss coefficient of the heat exchange link from the heating zone to the heat exchange zone. The heat loss coefficient is a parameter reflecting the proportion of heat loss from the heating zone to the heat exchange zone of the fumigation inhaler. This heat loss coefficient serves as the core basis for the initial heat exchange temperature calculation, accurately quantifying heat loss and avoiding insufficient heating temperature in the heating zone due to neglecting losses, ensuring that the aerosol temperature still meets the standard after heat exchange in the heat exchange zone.

[0029] In specific implementation, the initial heat exchange temperature of the heat exchange medium can be determined based on the target mist temperature of the traditional Chinese medicine compound liquid and the heat loss coefficient in the following manner: obtain the target temperature of the traditional Chinese medicine compound liquid, use the target mist temperature and the heat loss coefficient as reference parameters, and calculate the initial heat exchange temperature of the heat exchange medium using the heat balance calculation formula, i.e., initial heat exchange temperature = target mist temperature ÷ (1 - heat loss coefficient); wherein, the initial heat exchange temperature is the initial target temperature of the heat exchange medium in the heating area. This initial heat exchange temperature can provide a basic temperature reference for heating the heat exchange medium, compensate for the heat loss from the heating area to the heat exchange area, avoid the temperature deviating too much from the target range before subsequent correction, and reduce the difficulty of subsequent adjustment.

[0030] In specific implementation, the initial heat exchange temperature is corrected for environmental factors. The environmentally corrected heat exchange temperature can be obtained by the following method: the ambient temperature is collected by a thermistor sensor installed at the vent of the fumigation inhaler housing, and a pre-stored environmental temperature field correction factor table is used to match the correction factor corresponding to the current ambient temperature. The initial heat exchange temperature is then multiplied by the correction factor to obtain the environmentally corrected heat exchange temperature. The environmentally corrected heat exchange temperature is the temperature value obtained by adding the environmental temperature correction factor to the initial heat exchange temperature of the heat exchange medium. This environmentally corrected heat exchange temperature can offset the influence of the environmental temperature field on heat exchange and can adapt to different ambient temperatures (such as low temperature in winter and high temperature in summer). It avoids additional heat loss due to low ambient temperature or excessive temperature due to high ambient temperature, ensuring that the temperature of the heat exchange medium is not affected by the environment. The environmental temperature field correction factor table can be preset with correction factors of 1.10 for 5℃, 1.07 for 15℃, 1.04 for 25℃, 1.03 for 35℃, and 1.02 for 40℃. The corresponding factors between adjacent temperature points are calculated using linear interpolation.

[0031] It should be noted that in this application, the target heat exchange temperature is the final target temperature of the heat exchange medium in the heating area. This target heat exchange temperature takes into account heat loss, environmental impact and the heat-sensitive characteristics of traditional Chinese medicine compound, and is the final execution standard for heating. It can ensure that the heat exchange medium provides a precise heat source for heat exchange in the heat exchange area, ensuring that the drug mist reaches the target temperature and avoiding the destruction of the effective components of traditional Chinese medicine compound due to improper temperature.

[0032] In specific implementation, the environmental correction heat exchange temperature is further corrected based on the thermosensitive characteristics of the traditional Chinese medicine compound liquid. The target heat exchange temperature of the heat exchange medium in the heating area of ​​the fumigation inhaler can be obtained in the following way: a pre-stored traditional Chinese medicine compound thermosensitive characteristic correction table can be retrieved, and the corresponding thermosensitive correction value can be matched according to the type of traditional Chinese medicine compound. The environmental correction heat exchange temperature is added to the thermosensitive correction value to obtain the target heat exchange temperature of the heat exchange medium in the heating area. Among them, the thermosensitive correction value in the traditional Chinese medicine compound thermosensitive characteristic correction table can be set according to the compound components: the thermosensitive correction value corresponding to the compound containing volatile oils (such as chuanxiong and menthol) is +3℃, the thermosensitive correction value corresponding to the compound containing resins (such as frankincense and myrrh) is -2℃, and the thermosensitive correction value corresponding to the compound containing alkaloids (such as coptis and phellodendron) is 0℃.

[0033] In some embodiments, the heating power is adaptively adjusted based on the target heat exchange temperature and the temperature feedback signal of the heat exchange medium in the heating region to obtain a temperature-adjusted isothermal heat exchange medium, which can be achieved by the following steps: Acquire the temperature feedback signal of the heat exchange medium in the heating zone; The real-time temperature difference and temperature difference rate of the heat exchange medium in the heating zone are determined by the target heat exchange temperature and the temperature feedback signal. The heating power of the heating zone is adjusted based on the real-time temperature difference and the rate of change of temperature difference to obtain a constant-temperature heat exchange medium after temperature adjustment.

[0034] In specific implementation, the temperature feedback signal of the heat exchange medium in the heating area can be obtained in the following way: a temperature sensor installed in the middle of the medium circulation pipe in the heating area can be used to collect the temperature of the heat exchange medium in real time at a sampling frequency of 1kHz, and all collected temperatures can be filtered by moving average to remove abnormal values ​​that exceed the normal range (such as 30-70℃) to form a stable temperature feedback signal; wherein, the temperature feedback signal is a stable data signal that displays the temperature of the heat exchange medium in the heating area. This temperature feedback signal can provide real-time and accurate temperature basis for temperature difference calculation and heating power adjustment, and prevent the temperature of the heat exchange medium from getting out of control.

[0035] In specific implementation, determining the real-time temperature difference and temperature difference change rate of the heat exchange medium in the heating zone using the target heat exchange temperature and the temperature feedback signal can be achieved in the following way: All temperature differences of the heat exchange medium in the heating zone can be calculated using the formula: Temperature Difference = Target Heat Exchange Temperature - Temperature Value in Temperature Feedback Signal. The time sequence of all temperature differences is taken as the real-time temperature difference of the heat exchange medium in the heating zone. Then, with a fixed time interval of 1 second, all temperature change rates of the heat exchange medium in the heating zone are calculated using the formula: Change Rate = Temperature Difference / Fixed Time Interval. The time sequence of all change rates is taken as the real-time temperature difference of the heat exchange medium in the heating zone. The temperature difference change rate in the heating zone; wherein, the real-time temperature difference is a sequence of differences between the target heat exchange temperature and the current temperature of the heat exchange medium during the temperature adjustment process in the heating zone. This real-time temperature difference can intuitively reflect the degree of deviation between the current heat exchange medium temperature and the target value, clarifying the direction of "whether to adjust and by how much" for heating power adjustment, and avoiding blind temperature adjustment; the temperature difference change rate is a sequence of changes reflecting the changing trend of the temperature deviation of the heat exchange medium. This temperature difference change rate can help predict the temperature trend, such as the deviation expanding or shrinking, avoiding over-adjustment or under-adjustment when adjusting the heating power, and ensuring that the medium quickly stabilizes to a constant temperature state.

[0036] In specific implementation, the heating power of the heating area is adjusted based on the real-time temperature difference and the rate of change of the temperature difference to obtain the temperature-adjusted constant-temperature heat exchange medium. This can be achieved in the following way: The heating power adjustment amount can be determined based on the real-time temperature difference and the rate of change of the temperature difference using an incremental proportional-integral-derivative (PI-DI) control algorithm. Based on the heating power adjustment amount, the heating power of the heating area is adjusted by adjusting the duty cycle of the pulse width modulation drive signal of the positive temperature coefficient heater. The heating power is repeatedly corrected according to the temperature difference and the rate of change until the temperature of the heat exchange medium stabilizes within the target heat exchange temperature ±0.2℃ range for more than 30 seconds, thus obtaining the temperature-adjusted constant-temperature heat exchange medium. The PI-DI control algorithm can be preset with a proportional coefficient of 5.0, an integral coefficient of 0.2, and a derivative coefficient of 1.0. When the real-time temperature difference is greater than 1℃ and the rate of change is greater than 0.3℃ / s, the heating power is increased with an adjustment step of 50W; when the temperature difference is less than 0.5℃ and the rate of change is less than 0.1℃ / s, the heating power is decreased with an adjustment step of 20W.

[0037] It should be noted that in this application, the constant temperature heat exchange medium is a heat exchange medium whose temperature is stable within 0.2℃ above and below the target heat exchange temperature. This constant temperature heat exchange medium can provide a stable heat source for the heat exchange area, avoid the temperature of the atomized Chinese medicine compound liquid deviating from the target value due to fluctuations in the medium temperature, and ensure the therapeutic effect of fumigation inhalation.

[0038] In step 103, the constant temperature heat exchange medium is pumped into the heat exchange channel of the heat exchange area of ​​the fumigation inhaler, and the temperature sequence of the atomized Chinese medicine compound mist at the outlet of the heat exchange area is obtained.

[0039] In specific implementation, the constant-temperature heat exchange medium can be pumped into the heat exchange channel of the fumigation inhaler's heat exchange area in the following way: the constant-temperature heat exchange medium can be pumped into the heat exchange channel of the fumigation inhaler's heat exchange area using a brushless DC circulating pump. During the transport of the constant-temperature heat exchange medium, it first passes through a one-way valve, and then is divided into two paths by a diversion valve: one path enters the inner small heat exchange tube of the heat exchange area and flows from bottom to top along the tube; the other path enters the outer large heat exchange tube and flows from top to bottom along the tube. Both paths are sealed at the interface by silicone rubber sealing rings, ultimately forming a counter-current-cross-flow composite flow, ensuring that the medium uniformly fills the heat exchange channel and provides a stable heat source for subsequent drug mist heat exchange.

[0040] It should be noted that in this application, the temperature time series refers to the temperature data sequence of the traditional Chinese medicine compound mist at the outlet of the heat exchange area. This temperature time series can provide real-time and accurate data support for subsequent calculation of the temperature difference gradient of the mist and judgment of temperature stability, making the process of adjusting the heat exchange efficiency based on fuzzy reasoning more reliable, timely detecting the trend of mist temperature deviation, and ensuring that the mist temperature always meets the temperature requirements for the treatment of rheumatic and immune diseases.

[0041] In specific implementation, the temperature sequence of the atomized Chinese herbal compound mist at the outlet of the heat exchange area can be achieved in the following way: The Chinese herbal compound mist, after being atomized by the electrostatic atomizer of the fumigation inhaler, first enters the composite heat exchange channel of the heat exchange area, that is, the short straight mist delivery pipe between the inner small heat exchange tube and the outer large heat exchange tube to complete the heat exchange, and then is discharged from the mist delivery pipe at the outlet. The actual temperature of the mist can be synchronously collected at a frequency of 500 milliseconds / time by a digital temperature sensor installed on the inner wall of the mist delivery pipe outlet. The moving average filtering method is used to preprocess all the collected actual temperatures of the mist to remove outliers exceeding ±2℃ of the target mist temperature. Then, the preprocessed actual temperatures of all the drugs are arranged in the order of collection time to form the temperature sequence of the Chinese herbal compound mist at the outlet of the heat exchange area.

[0042] In step 104, the temperature difference gradient of the traditional Chinese medicine compound mist in the heat exchange region is determined according to the target mist temperature and the temperature time sequence. Then, fuzzy reasoning is performed on the temperature difference gradient and the thermal stability state of the constant temperature heat exchange medium to obtain the adaptive compensation factor of the heat exchange efficiency of the traditional Chinese medicine compound mist in the counter-current-cross-current composite heat exchange mode.

[0043] In some embodiments, reference Figure 3 The figure is an exemplary flowchart illustrating the determination of the temperature difference gradient according to some embodiments of this application. The determination of the temperature difference gradient of the traditional Chinese medicine compound mist in the heat exchange zone based on the target mist temperature and the temperature time sequence can be achieved using the following steps: In step 1041, the instantaneous temperature deviation between the actual temperature of the traditional Chinese medicine compound mist and the target mist temperature in the heat exchange area is determined based on the temperature time sequence. In step 1042, the instantaneous gradient sequence of the traditional Chinese medicine compound mist in the heat exchange area is determined based on the instantaneous temperature deviation; In step 1043, a composite compensation coefficient for the atomization and volatilization of the traditional Chinese medicine compound mist is generated based on the atomization amount of the medicine mist in the heat exchange area and the volatilization coefficient of the traditional Chinese medicine compound mist. In step 1044, the instantaneous gradient sequence is dynamically compensated using the composite compensation coefficient to obtain the temperature difference gradient of the traditional Chinese medicine compound mist in the heat exchange region.

[0044] In specific implementation, the instantaneous temperature deviation between the actual temperature of the traditional Chinese medicine compound mist and the target mist temperature in the heat exchange area, based on the temperature time sequence, can be achieved in the following way: the deviation value can be calculated based on the actual drug temperature in the temperature time sequence using the formula: instantaneous temperature deviation = actual mist temperature - target mist temperature. The time sequence of deviation values ​​at all times is then used as the instantaneous temperature deviation between the actual temperature of the traditional Chinese medicine compound mist and the target mist temperature in the heat exchange area. The instantaneous temperature deviation is a sequence of differences between the actual temperature of the traditional Chinese medicine compound mist and the target mist temperature during the temperature adjustment process in the heat exchange area. This instantaneous temperature deviation can reflect the degree to which the mist temperature deviates from the target value in real time, providing an initial deviation basis for subsequent temperature gradient calculation and temperature adjustment decisions, and avoiding the mist temperature exceeding the appropriate treatment range due to a lag in deviation perception.

[0045] In specific implementation, determining the instantaneous gradient sequence of the traditional Chinese medicine compound mist in the heat exchange area based on the instantaneous temperature deviation can be achieved in the following way: Using a fixed time interval of 500ms, the temperature deviation values ​​at consecutive moments are extracted from the instantaneous temperature deviation, and the instantaneous gradient is calculated using a first-order difference algorithm. That is, instantaneous gradient = (deviation value at the next moment - deviation value at the previous moment) ÷ time interval. This yields the instantaneous gradient for every two consecutive moments in the heat exchange area. Then, a sequence composed of all instantaneous gradients in chronological order is taken as the instantaneous gradient sequence of the traditional Chinese medicine compound mist in the heat exchange area. The instantaneous gradient sequence reflects the trend of the temperature deviation of the mist in the heat exchange area over time. This instantaneous gradient sequence can intuitively present the rate of increase or decrease in temperature deviation, helping to determine the direction of temperature change and providing trend data support for adjusting temperature control strategies, thus reducing blind temperature adjustments.

[0046] In specific implementation, the composite compensation coefficient for the atomization and volatilization of the traditional Chinese medicine compound atomized mist, based on the atomization volume of the medicine mist in the heat exchange area and the volatilization coefficient of the traditional Chinese medicine compound atomized mist, can be generated in the following way: First, the atomization volume of the medicine mist can be collected by the flow sensor built into the electrostatic atomizer, and the atomization volume correction factor can be calculated with 1 mL / min as the benchmark. That is, for every 0.5 mL / min increase in atomization volume, the atomization volume correction factor increases by 0.05. For example, the atomization volume of 1.5 mL / min corresponds to an atomization volume correction factor of 1.05. Then, the pre-stored volatilization coefficient table of traditional Chinese medicine compound atomized mist is retrieved to match the current traditional Chinese medicine compound atomized mist. The volatility coefficient of the medicinal mist is calculated, and a composite compensation coefficient for the atomization and volatilization of the traditional Chinese medicine compound medicinal mist is generated by using the composite compensation coefficient = atomization amount correction factor × volatility coefficient. This composite compensation coefficient is used to offset the interference of atomization amount fluctuations and medicinal liquid volatilization on the temperature gradient. This composite compensation coefficient can eliminate gradient calculation errors caused by changes in atomization amount and the volatilization of medicinal components, ensuring that subsequent temperature difference gradients can accurately reflect the actual dynamics of the medicinal mist temperature. The volatility coefficient table for traditional Chinese medicine compound formulas can be set according to the compound ingredients; for example, the volatility coefficient of a traditional Chinese medicine compound containing menthol is 1.2, and the volatility coefficient of a traditional Chinese medicine compound containing danshen is 1.0.

[0047] It should be noted that, in this application, the temperature difference gradient is an instantaneous gradient sequence reflecting the dynamic change of the temperature deviation of the medicinal mist in the heat exchange area. This temperature difference gradient can provide a precise basis for the power adjustment of the temperature control module in the heat exchange area, ensuring that the temperature of the medicinal mist quickly and stably approaches the target value, and improving the accuracy and stability of the temperature control of the fumigation medicinal mist. In specific implementation, the temperature difference gradient of the traditional Chinese medicine compound medicinal mist in the heat exchange area can be obtained by dynamically compensating the instantaneous gradient sequence through the composite compensation coefficient in the following way: the composite compensation coefficient can be multiplied by the instantaneous gradient in the instantaneous gradient sequence for dynamic compensation, and the compensated sequence can be used as the temperature difference gradient of the traditional Chinese medicine compound medicinal mist in the heat exchange area.

[0048] In some embodiments, the adaptive compensation factor for the heat exchange efficiency of the traditional Chinese medicine compound mist under the counter-current-cross-current composite heat exchange mode can be obtained by performing fuzzy reasoning on the temperature difference gradient and the thermal stability state of the isothermal heat exchange medium using the following steps: Determine the thermal stability state of the isothermal heat exchange medium; By performing dual-input fuzzy reasoning on the temperature difference gradient and the thermal stability state, the initial heat transfer compensation coefficient of the traditional Chinese medicine compound mist in the heat transfer region is obtained. Based on the counter-flow-crossflow composite heat transfer mode, a composite flow pattern correction factor is introduced to correct the flow pattern of the initial heat transfer compensation coefficient, thereby obtaining the flow pattern adaptation compensation coefficient. Based on the viscosity grade of the traditional Chinese medicine compound liquid, the heat transfer hysteresis compensation coefficient of the flow pattern adaptation is performed to obtain the adaptive compensation factor of the heat transfer efficiency of the traditional Chinese medicine compound mist in the counter-current-cross-current composite heat transfer mode.

[0049] It should be noted that in this application, the thermal stability state is a thermal state classified after quantifying the amplitude and frequency of temperature fluctuations in the isothermal heat exchange medium, including: strong steady state, weak steady state and unstable state. This thermal stability state can reflect whether the thermal characteristics of the heat exchange medium are stable, providing accurate input of the medium's thermal state for subsequent fuzzy inference, avoiding deviations in heat exchange compensation calculations due to ignoring fluctuations in the medium's thermal stability, and ensuring the reliability of the basic data for regulation.

[0050] In specific implementation, the thermal stability state of the constant-temperature heat exchange medium can be determined in the following way: the temperature data of the constant-temperature heat exchange medium can be continuously collected for 30 seconds by a temperature sensor installed in the outlet pipe of the heating area at a sampling frequency of 1kHz, and outliers deviating from the mean ±0.3℃ in the temperature data are removed. Then, the temperature fluctuation amplitude and fluctuation frequency of the remaining data are calculated, and the thermal stability state is divided according to a preset standard: a strong steady state is defined as a temperature fluctuation amplitude of less than or equal to 0.2℃ and a fluctuation frequency of less than or equal to 1; a weak steady state is defined as a temperature fluctuation amplitude of 0.2-0.3℃ and a fluctuation frequency of 2-3; and an unstable state is defined as a temperature fluctuation amplitude greater than 0.3℃ and a fluctuation frequency ≥ 4. Here, the temperature fluctuation amplitude is the difference between the maximum and minimum values, and the fluctuation frequency is the number of times the temperature fluctuation amplitude is greater than 0.2℃.

[0051] In specific implementation, the initial heat transfer compensation coefficient of the traditional Chinese medicine compound mist in the heat transfer region can be obtained by performing dual-input fuzzy inference on the temperature difference gradient and the thermal stability state in the heat transfer region. This can be achieved in the following way: First, the temperature difference gradient and the thermal stability state can be fuzzified, that is, the temperature difference gradient can be divided into 5 fuzzy subsets (negative large, negative small, zero, positive small, positive large) and the membership degree can be calculated using a triangular membership function; the thermal stability state can be divided into 3 fuzzy subsets (strong steady state, weak steady state, unstable state) and the membership degree can be calculated using a trapezoidal membership function; then, pre-stored fuzzy inference rules (such as temperature difference gradient) can be called. The process involves determining the initial heat transfer compensation coefficient (1.2) for the hot and unstable state. The Mandani inference method is used to calculate the fuzzy relationship based on the temperature difference gradient and the membership degree of the thermal stability state, outputting a fuzzy set. Then, the centroid method is used to defuzzify the fuzzy set, transforming it into the initial heat transfer compensation coefficient for the traditional Chinese medicine compound mist in the heat transfer region. This initial heat transfer compensation coefficient is a coefficient that preliminarily quantifies the heat transfer regulation requirements in the heat transfer region. It is generated based on dual-parameter inference, avoiding the limitations of single-parameter calculations, and can initially match the heat transfer regulation intensity, providing a basic coefficient for subsequent flow pattern and viscosity correction, and reducing the accumulation of errors in the final compensation.

[0052] It should be noted that in this application, the counter-current-crossflow composite heat exchange mode is a heat exchange structure that combines high-efficiency counter-current heat exchange with good temperature uniformity crossflow heat exchange. It can take into account both the heat exchange efficiency and temperature stability of the Chinese herbal compound mist, avoid the local overheating of the mist that may be caused by single counter-current heat exchange, and solve the problem of low efficiency of single crossflow heat exchange, thus meeting the dual requirements of "high efficiency + stable temperature" for temperature regulation in the heat exchange area.

[0053] In specific implementation, based on the counter-current-crossflow composite heat transfer mode, a composite flow pattern correction factor is introduced to correct the initial heat transfer compensation coefficient. The resulting flow pattern adaptation compensation coefficient can be achieved as follows: the composite flow pattern correction factor, obtained through previous experiments, can be acquired, and the flow pattern adaptation compensation coefficient can be calculated using the formula: Flow pattern adaptation compensation coefficient = Initial heat transfer compensation coefficient × Composite flow pattern correction factor. This flow pattern adaptation compensation coefficient is the heat transfer compensation coefficient corrected by the composite flow pattern correction factor. This coefficient adapts to the differences in heat transfer efficiency between different flow sections under the counter-current-crossflow composite heat transfer mode and can offset the composite flow pattern differences. The inherent difference in heat transfer efficiency between counter-current and cross-current flow patterns avoids mismatch between the compensation coefficient and the actual heat transfer scenario due to different flow patterns, thus improving the targeting of adjustment. The composite flow pattern correction factor is a fixed correction parameter set based on the measured difference in heat transfer efficiency between the counter-current and cross-current sections. For example, under the same medium flow velocity, the heat transfer efficiency of the counter-current section is 8% higher than that of the cross-current section. Based on this, the composite flow pattern correction factor is determined to be 1.08. This composite flow pattern correction factor can quantify the correction of the heat transfer efficiency deviation of the composite flow pattern. It can directly and quickly correct the initial coefficient through the preset factor, simplifying the calculation process while ensuring that the compensation coefficient fits the actual heat transfer characteristics of the composite flow pattern.

[0054] In specific implementation, the adaptive compensation factor for the heat exchange efficiency of the traditional Chinese medicine compound liquid under the counter-current-cross-current combined heat exchange mode can be obtained by performing heat transfer hysteresis compensation on the flow pattern adaptation compensation coefficient according to the viscosity level of the traditional Chinese medicine compound liquid. This can be achieved in the following way: a pre-stored traditional Chinese medicine compound viscosity correction coefficient table can be retrieved, the viscosity level of the traditional Chinese medicine compound liquid can be detected by a liquid viscosity sensor, and a viscosity correction coefficient can be matched in the traditional Chinese medicine compound viscosity correction coefficient table according to the viscosity level. Then, the adaptive compensation factor for the heat exchange efficiency of the traditional Chinese medicine compound liquid under the counter-current-cross-current combined heat exchange mode can be calculated by adaptive compensation factor = flow pattern adaptation compensation coefficient × viscosity correction coefficient. The adaptive compensation factor is obtained by adjusting the flow pattern and compensating for the viscosity hysteresis of the traditional Chinese medicine compound liquid. The final coefficient for heat exchange regulation requirements in the compensated heat exchange area is determined by the adaptive compensation factor. This factor can dynamically adapt to changes in the state of the heat exchange medium, flow pattern differences, and drug properties. It responds in real time to the influence of multiple variables such as fluctuations in thermal stability, flow pattern differences, and changes in drug viscosity, accurately matching the heat exchange regulation requirements. This ensures that the temperature of the herbal compound atomized liquid remains stable and meets the standards, avoiding the occurrence of substandard atomized liquid temperatures due to heat exchange lag in high-viscosity liquids. The viscosity correction coefficient table for herbal compound atomized liquids can be established based on measured viscosity data. The correction coefficient is 0.98 for low-viscosity compound atomized liquids with a viscosity less than 50 mPa·s, 1.0 for medium-viscosity compound atomized liquids with a viscosity between 50 and 100 mPa·s, and 1.03 for high-viscosity compound atomized liquids with a viscosity greater than 100 mPa·s.

[0055] In step 105, the rotational speed of the circulating pump in the fumigation inhaler is controlled according to the adaptive compensation factor to adjust the heat exchange intensity between the herbal compound mist and the heat exchange medium.

[0056] In some embodiments, controlling the rotational speed of the circulating pump in the fumigation inhaler according to the adaptive compensation factor to adjust the heat exchange intensity between the traditional Chinese medicine compound mist and the heat exchange medium can be achieved by the following steps: The target speed command for controlling the circulating pump in the fumigation inhaler is generated based on the linear correspondence between the adaptive compensation factor and the target speed of the circulating pump. The target speed command is converted into a control signal to adjust the speed of the circulating pump through a brushless motor driver, thereby changing the flow rate of the heat exchange medium in the heat exchange channel to adjust the heat exchange intensity between the traditional Chinese medicine compound mist and the heat exchange medium.

[0057] In specific implementation, the generation of the target speed command for controlling the circulating pump in the fumigation inhaler based on the linear correspondence between the adaptive compensation factor and the target speed of the circulating pump can be achieved in the following way: the target speed can be calculated by calling the pre-stored linear correspondence table between the adaptive compensation factor and the target speed of the circulating pump, and a target speed command containing the target speed value and execution priority can be generated; wherein, the target speed command is a control command for adjusting the speed of the circulating pump. This target speed command can transform the abstract compensation requirement into specific speed parameters, ensuring that the adjustment of the circulating pump has a precise basis, thereby stabilizing the control of the heat exchange medium flow rate and heat exchange intensity, and ensuring that the aerosol temperature approaches the target value; wherein, the linear correspondence table between the adaptive compensation factor and the target speed of the circulating pump can be set through prior experimental verification, that is, the adjustment range of the heat exchange medium flow rate and the corresponding aerosol temperature can be measured at different circulating pump speeds to determine the linear ratio between the speed change and the heat exchange intensity adjustment, thereby establishing the mapping relationship between the adaptive compensation factor and the speed. For example, when the compensation factor is 1.0, the corresponding rated speed is 1500 rpm. For every increase or decrease of 0.1, the target speed increases or decreases by 150 rpm.

[0058] In specific implementation, the target speed command is converted into a control signal to adjust the speed of the circulating pump through a brushless motor driver, thereby changing the flow rate of the heat exchange medium in the heat exchange channel to adjust the heat exchange intensity between the herbal compound mist and the heat exchange medium. This can be achieved in the following way: the target speed command can be converted into a 10kHz pulse modulation signal and transmitted to the brushless motor driver through a serial peripheral interface communication protocol. The brushless motor driver outputs a drive current to the circulating pump according to the duty cycle of the pulse modulation signal. At the same time, the Hall speed sensor integrated in the circulating pump body can collect the actual speed in real time and feed the data back to the control unit to calculate the speed deviation. If the deviation is greater than 50 rpm, the duty cycle of the pulse modulation signal is adjusted in steps of 1% to form a closed-loop control, ensuring that the deviation between the actual speed and the target speed is less than or equal to 30 rpm. As the speed of the circulating pump increases, the flow rate of the heat exchange medium in the heat exchange channel increases synchronously, thereby linearly adjusting the heat exchange intensity between the herbal mist and the medium, so that the temperature of the herbal mist stabilizes and approaches the target value.
