Description

Technical Field

[0001] The present invention relates to the technical field of air purification, in particular to a bedside table with a negative ion purification function and a working method thereof. Background Art

[0002] As the demand for healthy homes escalates, the functional limitations of traditional bedside tables and the technical bottlenecks of stand-alone air purification devices are becoming increasingly prominent. Existing filter-type purifiers rely on physical interception mechanisms, and have problems such as filtration efficiency being limited by static matching of filter apertures, high costs for frequent replacement, and noise interference from fan operation. Conventional negative ion devices, while offering the advantage of no consumables, have fixed release concentrations, directions, and frequencies, and are unable to adaptively adjust based on dynamic environmental parameters (such as sudden changes in humidity and day-night light levels) or personalized user health needs (such as respiratory sensitivity thresholds and allergen distribution). In medical scenarios, in particular, existing technologies struggle to integrate real-time user physiological indicators (such as abnormal heart rate fluctuations and respiratory rate disorders), symptom types (such as mucosal irritation caused by colds and trigger thresholds for allergic rhinitis), and environmental parameters, leading to an imbalance between purification efficiency and perceived comfort, and even exacerbating symptoms due to uncontrolled ion concentrations. These shortcomings demonstrate an urgent need to address the challenges of collaborative optimization of environmental adaptability, health and safety, and purification efficiency in traditional technologies through multimodal data fusion and dynamic control mechanisms. Summary of the Invention

[0003] In response to the above-mentioned defects, the purpose of the present invention is to propose a bedside table with negative ion purification function and its working method, aiming to solve the adaptability problem between environmental changes and users' personalized health needs, as well as the problem of difficulty in balancing purification efficiency and health and safety due to insufficient coordinated regulation of multiple parameters.

[0004] To achieve this object, the present invention adopts the following technical solutions:

[0005] A bedside table with a negative ion purification function, comprising an environment monitoring module, a user monitoring module, a first control module, a second control module and a negative ion generator;

[0006] The negative ion generator includes a high-voltage package and a plurality of release media, wherein the high-voltage package is used to output different voltages to different release media to provide a high-voltage electric field required for ionization;

[0007] The environmental monitoring module is used to obtain environmental parameters, including real-time weather data, air humidity and indoor light intensity;

[0008] The user monitoring module is used to obtain user biometric data, which includes user physiological status indicators, health tags and disease symptom types;

[0009] The first control module is used to control the negative ion release concentration and diffusion range of the negative ion generator according to the air humidity, health label and disease symptom type;

[0010] The second control module is used to control the negative ion release frequency and action direction of the negative ion generator according to the user's real-time physiological status indicators, the relative position of the bedside table and the user, weather data and indoor light intensity.

[0011] Preferably, the first control module includes:

[0012] When the health tag includes a respiratory sensitivity indicator and the current indoor air humidity exceeds a preset humidity threshold, the following operations are performed:

[0013] Analyze the negative ion concentration safety range corresponding to the respiratory sensitivity indicator, and divide the high-voltage package voltage step adjustment level according to the degree of deviation of the current indoor air humidity from the preset humidity threshold;

[0014] When the symptom type is marked as a cold-related disease, the following operations are performed:

[0015] Analyze the temperature-related threshold value in the medical parameters corresponding to the cold-related diseases. When the user's real-time body temperature exceeds the temperature-related threshold value, divide the adjustment stage into several stages according to the degree of temperature excess. Each stage corresponds to the increment and duration of the high-voltage transformer voltage.

[0016] In the first adjustment stage, a first boosting operation is performed on the high-voltage transformer voltage according to the step adjustment level corresponding to the humidity deviation degree, and the first preset time period is maintained;

[0017] If the body temperature continues to exceed the standard and the symptom relief period has not ended, the next adjustment stage is entered, and the increment of the high-voltage coil voltage is reduced according to the remaining time ratio of the symptom relief period, and the duration is extended to a second preset time.

[0018] Preferably, the first control module includes:

[0019] If the symptom type is labeled as allergic rhinitis or skin disease, do the following:

[0020] Parsing the allergen identifier recorded in the health label, parsing the environmental trigger conditions corresponding to the allergen, and compressing the fluctuation range of the negative ion concentration safety interval according to the environmental trigger conditions;

[0021] When the air humidity or indoor light intensity meets the environmental trigger condition, the adjustment amplitude of the high-voltage package voltage is limited to half of the compressed interval, and the voltage transition time is extended to the preset symptom adaptation period.

[0022] Preferably, the release medium is installed on the top, side and bottom of the bedside table respectively, and the first control module includes:

[0023] When the health tag includes a space-sensitive identifier and the air humidity exceeds a preset humidity threshold, the following operations are performed:

[0024] Analyze the user's taboo direction based on the historical trigger records of the space-sensitive identifier and the current air humidity distribution characteristics;

[0025] closing at least one medium release branch directly associated with the somatic discomfort area marked with the symptom type in the taboo direction;

[0026] Activate the remaining release medium branches in the taboo directions that are far away from the user activity hotspots and where the air humidity is lower than the safety threshold, and limit the number of connections in each direction to not exceed the preset connection upper limit of the corresponding direction.

[0027] Preferably, the release medium is installed on the top, side and bottom of the bedside table respectively, and the first control module includes:

[0028] When the symptom type is labeled as respiratory disease and the health label includes a respiratory sensitivity area, perform the following operations:

[0029] Determine the negative ion diffusion taboo direction based on the distribution density of the air humidity in each area of the bedside table and the geometric position of the respiratory sensitive area;

[0030] In the forbidden orientation, closing at least half of the release medium branches associated with abnormal fluctuations in the respiratory rate in the user's real-time physiological status indicator;

[0031] Activate the release medium branch in the direction of the air humidity gradient decrease in the taboo direction, and adjust the number of activated branches according to the symptom relief cycle.

[0032] Preferably, the second control module includes:

[0033] When abnormal fluctuations in the user's heart rate or breathing rate are detected in the user's real-time physiological status indicators, the following actions are performed:

[0034] According to the amplitude of the abnormal fluctuation, the emergency adjustment level of the negative ion release frequency is divided, and the release medium branch associated with the position closest to the user's current body position is preferentially closed;

[0035] Based on the real-time relative position of the bedside table and the user, the electric field excitation timing of the remaining release medium is redistributed, so that the release frequency of the release medium branch outside the preset safe distance from the user's body surface is increased;

[0036] If the indoor light intensity is lower than the circadian rhythm threshold and the weather data is marked as calm wind, the excitation interval of the high-frequency release medium will be extended until the user's physiological state indicators return to the preset safe range.

[0037] Preferably, the second control module includes:

[0038] When an abnormal heart rate or breathing rate is detected in the user's real-time physiological status indicators, the following actions are performed:

[0039] Determining the avoidance priority of the negative ion action direction according to the extent to which the abnormal indicator deviates from the preset safety interval;

[0040] Based on the real-time relative position of the bedside table and the user, the side orientation and the release medium branch at the bottom of the bedside table are activated to form a surrounding electric field distribution;

[0041] If the wind force level in the weather data is higher than the preset wind force value, the electric field phase difference of the activation medium branch is adjusted to guide the negative ions to diffuse in the opposite direction of the wind force;

[0042] When the indoor light intensity is lower than the circadian rhythm threshold, the electric field intensity gradient of the release medium at the bottom is enhanced, so that negative ions are enriched in the low-light area away from the user's body surface.

[0043] A method for operating a bedside table with a negative ion purification function, comprising the bedside table with a negative ion purification function as described above, the method comprising:

[0044] Acquiring environmental parameters, including real-time weather data, air humidity, and indoor light intensity;

[0045] Acquiring user biometric data, including user physiological status indicators, health tags, and disease symptom types;

[0046] Controlling the negative ion release concentration and diffusion range of the negative ion generator according to the air humidity, health label and disease symptom type;

[0047] The negative ion generator's negative ion release frequency and action direction are controlled based on the user's real-time physiological status indicators, the relative position of the bedside table and the user, weather data, and indoor light intensity.

[0048] One of the above technical solutions has the following advantages or beneficial effects:

[0049] The present invention adjusts the concentration of negative ions in real time based on air humidity, suppresses the problem of negative ion agglomeration failure in high humidity environments, and maintains purification efficiency in low humidity scenarios; combines weather data with indoor light intensity to predict air flow trends and circadian rhythm requirements, optimizes the diffusion path of negative ions through phase difference adjustment and electric field gradient distribution, and avoids purification blind spots in still wind or strong light environments; automatically divides taboo directions and turns off high-risk release media based on user health labels (such as respiratory sensitivity markers) and symptom types (such as asthma, allergies), blocking the enrichment stimulation of negative ions in sensitive areas; maintains the environment by activating safe omnidirectional media and dynamically compensating voltage. Maintain the purification intensity in non-sensitive areas to achieve a spatial balance between local inhibition and global enhancement; when abnormal fluctuations in heart rate or respiratory rate are detected, the proximal release medium is shut down first to reduce the risk of immediate stimulation, while the release frequency or electric field strength of the distal release medium is increased to compensate for the purification capacity in a targeted manner; the surround electric field distribution is optimized in combination with the user's body posture and relative position to ensure that the direction of negative ion action is accurately matched with the user's activity hotspot area; the number of activated branches and the voltage increase and attenuation rate are dynamically adjusted based on the symptom relief cycle, while ensuring the safety threshold in the acute phase, the purification energy efficiency is gradually restored to avoid energy waste caused by long-term high-load operation.

[0055] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0056] In the present invention, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0057] A bedside table with negative ion purification function, such as Figure 1 As shown, in a preferred embodiment of the present invention, the bedside table includes an environment monitoring module, a user monitoring module, a first control module, a second control module and a negative ion generator. The environment monitoring module, the user monitoring module, the first control module, the second control module and the negative ion generator can be integrated into a bedside table system with a negative ion purification function, so the systems mentioned below are all bedside table systems with a negative ion purification function;

[0058] The negative ion generator includes a high voltage package and several release media, such as Figure 2 As shown, a release medium 1 is provided at each position of the bedside table. There may be multiple release media 1 at each position and they may be distributed at different positions in the same position. The high-voltage package is used to output different voltages to different release media to provide the high-voltage electric field required for ionization.

[0059] The high-voltage transformer can take 220V AC as input. It first passes through an EMC circuit to suppress electromagnetic interference, minimizing its impact on the power supply and equipment. The rectifier and filter circuits then convert the AC to DC and filter out ripple, resulting in smooth DC power. This power then enters the switching power supply circuit, which stabilizes the output voltage and adjusts the power to provide an appropriate input for the transformer. The transformer then steps down the voltage, outputting a low voltage, such as 12V, for the high-voltage transformer and other circuits, ensuring safe and stable equipment operation. The MCU then transmits control signals to the transformer's switching circuit, which, in conjunction with the self-oscillator circuit, converts the low voltage to a negative high voltage, such as -5kV. This creates the necessary conditions for ionizing the air and generating negative charges. Ultimately, these negative charges combine with oxygen to form negative oxygen ions, effectively purifying the air.

[0060] The environmental monitoring module is used to obtain environmental parameters, including real-time weather data, air humidity and indoor light intensity;

[0061] Specifically, the environmental monitoring module aims to build a dynamic environmental information model so that the operating parameters of the negative ion generator can be precisely adjusted based on environmental conditions. For example, in environments with high humidity, the negative ion release strategy may need to be adjusted to prevent the high humidity from causing negative ions to aggregate and limit purification effectiveness. Environmental factors such as indoor air quality also vary under different weather and lighting conditions. Properly acquiring these parameters provides the foundation for subsequent personalized purification solutions.

[0062] Real-time weather data refers to the current weather conditions obtained through the Internet interface or external meteorological sensors, such as sunny days, rainy days, foggy days, etc. It can reflect the possible impact of the outdoor environment on indoor air quality (such as opening windows for ventilation during a nap), which in turn affects the negative ion purification strategy; air humidity is an indicator of indoor air moisture content measured by a humidity sensor. It is directly related to the existence state and migration ability of negative ions in the air. Too high humidity may make negative ions easily combine with water molecules and affect the purification effect. Too low humidity may cause air dryness, affecting comfort and partial purification reactions; indoor light intensity is detected by a photosensor. Under different light intensities, the indoor environment changes. The light intensity is used to match the user's circadian rhythm (such as reducing the release intensity at night to avoid interfering with sleep).

[0063] Regarding the acquisition of environmental parameters, one implementation method is to use Internet of Things technology to obtain real-time weather data by accessing the local meteorological service interface. At the same time, a humidity sensor and a light sensor are built into the bedside table to measure the air humidity and indoor light intensity in real time respectively. This method can quickly and easily obtain accurate external weather information and combine it with internal environmental parameters to provide comprehensive data support for subsequent regulation; another implementation method is to rely solely on a simple environmental monitoring module equipped on the bedside table itself to regularly collect air humidity and light intensity in a small surrounding area. This method is relatively low-cost and can be used in scenarios where the indoor environment is relatively stable and the requirements for external weather correlation are not high.

[0064] The user monitoring module is used to obtain user biometric data, which includes user physiological status indicators, health tags and disease symptom types;

[0065] Specifically, the user monitoring module can use various types of biological monitoring equipment or health data interfaces to collect user biometric data such as physiological status indicators (such as heart rate, respiratory rate, etc.), health labels (such as label information indicating whether the user has health conditions such as respiratory diseases) and symptom types. Its purpose is to achieve personalized air purification adjustment based on the user's own health status and immediate physiological state, and meet the different purification needs of different users due to health differences. For example, users with sensitive respiratory tracts need more suitable negative ion concentrations and purified environments.

[0066] User physiological status indicators refer to data obtained through monitoring with wearable devices that reflect the current state of the user's body. For example, abnormal fluctuations in heart rate may indicate that the user is in a state of stress or physical discomfort, and irregular breathing may indicate respiratory problems. These indicators can directly reflect the degree and direction of the user's immediate physical health condition and the urgent need for air purification. The health label is a general labeling of the user's long-term health status, such as "allergic constitution" or "chronic bronchitis patient". It allows the system to understand the user's past health focus so as to adjust the purification strategy in a long-term and targeted manner. The symptom type is a classification of the user's current specific symptoms, such as mucosal irritation caused by colds, allergic rhinitis, etc. Different symptoms correspond to different pathological mechanisms and sensitive points to the air environment, and the purification plan can be accurately optimized based on this.

[0067] For the user monitoring module, one feasible approach is to integrate data with the user's smart wearable health bracelet or medical health monitoring device to obtain real-time physiological status indicators such as heart rate and respiratory rate. At the same time, users can enter their health tags and symptom types on a mobile app connected to the bedside table. This approach can integrate real-time physiological data with the health background information actively provided by the user to achieve a comprehensive and dynamic user health profile, facilitating subsequent precise control. Another approach is to equip the bedside table with simple biometric monitoring sensors, such as heart rate sensing areas on the handles, to obtain simple physiological data when the user touches it. This approach can also obtain some real-time physiological information to a certain extent and is useful in scenarios where users use the bedside table occasionally and have extremely high privacy requirements. Combining the former comprehensive data integration with the latter simple self-monitoring can ensure the accurate and comprehensive acquisition of primary data, while using simple self-monitoring as a supplement or emergency measure to further improve the collection of user biometric data, so that purification adjustments are more closely aligned with the user's actual health changes and achieve better personalized purification effects.

[0068] The first control module is used to control the negative ion release concentration and diffusion range of the negative ion generator according to the air humidity, health label and disease symptom type;

[0069] For the first control module, based on the key factors such as the acquired air humidity, user health label and symptom type, the preset control logic is used to adjust the electric field strength output by the high-voltage package in the negative ion generator and the working state of the release medium, thereby controlling the negative ion release concentration and diffusion range. The purpose is to make precise adaptations based on the behavioral characteristics of negative ions in different humidity environments and the requirements for the appropriate contact amount and spatial range of negative ions under different user health conditions. For example, in a dry environment, the concentration can be appropriately increased to enhance the purification effect, and for users with sensitive respiratory tracts, the diffusion range can be controlled to avoid excessive stimulation, etc., thereby ensuring the effectiveness of purification and health safety.

[0070] The second control module is used to control the negative ion release frequency and action direction of the negative ion generator according to the user's real-time physiological status indicators, the relative position of the bedside table and the user, weather data and indoor light intensity.

[0071] For the second control module, comprehensive consideration is given to the user's real-time physiological status indicators (which can reflect the user's dynamic demand for air purification based on their immediate physical condition), the relative position of the bedside table and the user (determining the optimal spatial directionality of the negative ion effect, that is, taking into account the influence of distance and direction on the path and effect of negative ions reaching key areas such as the user's breathing area), weather data (wind force, rainfall) used to predict the impact of air flow on the diffusion of negative ions, and indoor light intensity (people's activity status and indoor ventilation may change under different lighting conditions. For example, during the day when the light is strong and users are active, purification assistance of different frequencies and directions may be required). The release frequency is changed by adjusting the driving signal frequency of the negative ion generator, and the orientation of the release medium is adjusted or the direction of action is changed by using a guide device. The purpose is to enable negative ions to act on the areas around the user that need purification most at the right time and in the right direction, thereby improving the timeliness and accuracy of purification. For example, in a calm wind environment, negative ions are guided to diffuse toward the pollution source in a directional manner, replacing the passive interception mechanism of the filter-type purifier.

[0072] Preferably, the first control module includes:

[0073] When the health tag includes a respiratory sensitivity indicator and the current indoor air humidity exceeds a preset humidity threshold, the following operations are performed:

[0074] Analyze the negative ion concentration safety range corresponding to the respiratory sensitivity indicator, and divide the high-voltage package voltage step adjustment level according to the degree of deviation of the current indoor air humidity from the preset humidity threshold;

[0075] When the symptom type is marked as a cold-related disease, the following operations are performed:

[0076] Analyze the temperature-related threshold value in the medical parameters corresponding to the cold-related diseases. When the user's real-time body temperature exceeds the temperature-related threshold value, divide the adjustment stage into several stages according to the degree of temperature excess. Each stage corresponds to the increment and duration of the high-voltage transformer voltage.

[0077] In the first adjustment stage, a first boosting operation is performed on the high-voltage transformer voltage according to the step adjustment level corresponding to the humidity deviation degree, and the first preset time period is maintained;

[0078] If the body temperature continues to exceed the standard and the symptom relief period has not ended, the next adjustment stage is entered, and the increment of the high-voltage coil voltage is reduced according to the remaining time ratio of the symptom relief period, and the duration is extended to a second preset time.

[0079] Assuming that the user's health label contains "asthma" (respiratory sensitivity indicator), the corresponding negative ion concentration safety range is 800-1500ions / cm 3 When the current indoor air humidity is detected to be 72% (the preset threshold is 60%, exceeding the standard by 12%), the first control module divides the humidity deviation into 4% steps and adjusts the level to three levels (12% ÷ 4%). Each step corresponds to a 1kV increase in the high-voltage transformer voltage (reference voltage -5kV → target -8kV), corresponding to a negative ion concentration of approximately 1100ions / cm 3 At the same time, the user's symptom type is marked as "viral cold", the body temperature associated threshold in the medical parameters is 37.5℃, and the real-time body temperature is 38.2℃ (0.7℃ above the standard), triggering a phased adjustment: in the first stage, the voltage is increased to -8kV according to the humidity step number and maintained for 30 minutes. At this time, the negative ion concentration reaches 73% of the safe range (1100 / 1500); if the body temperature continues to exceed the standard and the symptom relief period remains for 4 days (total period is 7 days, remaining ratio is 57%), it enters the second stage, the voltage increase is attenuated to 57% of the original value (1kV / level × 57% ≈ 0.57kV / level), and the total increase is reduced to 1.71kV (-5kV→-6.71kV, rounded to negative 6.5kV), corresponding to a concentration of about 900ions / cm 3 (lower limit of the safety range), the duration is extended to 52 minutes; if it is still not relieved, the third stage voltage is reduced to -5.57kV (5kV+0.57kV), and the concentration is reduced to 800ions / cm 3 (safety lower limit), the duration is extended to 90 minutes. Through the gradual increase and attenuation of 1kV per level, the -8kV rapid purification (1100ions / cm 3 ), and gradually converges to the safe lower limit (900→800ions / cm 3 ), balancing the need for sudden environmental purification with long-term symptom tolerance with a gentler concentration gradient.

[0080] In general, when it is detected that the air humidity exceeds the standard, the system automatically divides the adjustment levels into steps, and gradually increases the high-voltage coil voltage according to the degree of humidity deviation, ensuring that the negative ion concentration is within the safe threshold to counteract the attenuation effect caused by humidity. For cold-like symptoms, the voltage increase is adjusted in stages based on the real-time body temperature exceeding the standard. In the initial stage, the voltage is increased according to the humidity demand to maintain the basic purification efficiency. If the body temperature continues to be abnormal, the voltage increase is dynamically attenuated according to the symptom relief cycle and the action time is extended, gradually converging the negative ion concentration to the safe middle and lower limits to prevent high-concentration release from causing mucosal dryness or immune overload. Through the synergistic effect of humidity-driven concentration gradient regulation and body temperature-triggered dynamic attenuation mechanism, local irritation is suppressed in respiratory sensitive scenarios, and the purification demand and physiological tolerance are balanced during the cold and fever period, achieving dual adaptation of safety and environmental mutation response.

[0081] Furthermore, the first control module includes:

[0082] If the symptom type is labeled as allergic rhinitis or skin disease, do the following:

[0083] Parsing the allergen identifier recorded in the health label, parsing the environmental trigger conditions corresponding to the allergen, and compressing the fluctuation range of the negative ion concentration safety interval according to the environmental trigger conditions;

[0084] When the air humidity or indoor light intensity meets the environmental trigger condition, the adjustment amplitude of the high-voltage package voltage is limited to half of the compressed interval, and the voltage transition time is extended to the preset symptom adaptation period.

[0085] For example, when the user's symptom type is marked as "dust mite allergic rhinitis", the allergen recorded in the health tag is marked as "dust mite", and the environmental trigger condition is analyzed as humidity ≥ 70% or light ≥ 500 lux, the first control module will increase the original negative ion concentration safety range (1000-5000ions / cm 3 ) compressed to 1200-3000ions / cm 3 (The fluctuation range is reduced by 60%). When the current air humidity is detected to be 75% (humidity condition is triggered), the voltage adjustment range of the high-voltage package is limited to half of the compressed range (such as ±900ions / cm 3 The corresponding voltage is ±1.8kV), and the adjustment range of the reference voltage of -5kV is limited to -3.2kV--6.8kV. At the same time, the voltage transition time is extended from the default 10 minutes to 24 hours (symptom adaptation period). This operation suppresses the fluctuation of negative ion concentration in the high-humidity environment of dust mites by compressing the concentration range, limiting the amplitude of voltage mutation (such as prohibiting a sudden increase from -5kV to -10kV), and through 24-hour gradual voltage adjustment (such as increasing the voltage by 0.1kV per hour), the patient's nasal mucosa gradually adapts to the changes in negative ion concentration, avoiding sudden concentration switching that causes sneezing or skin itching.

[0086] In general, in this embodiment, when the user's symptom type is allergic rhinitis or skin disease, the environmental trigger conditions corresponding to the allergen identification (such as humidity or light thresholds) are analyzed to compress the fluctuation range of the negative ion concentration safety interval, thereby suppressing the risk of high-concentration negative ions getting out of control in a specific environment; when it is detected that the environmental parameters meet the trigger conditions, the adjustment amplitude of the high-voltage package voltage is limited to half of the compressed interval to prevent voltage mutations from causing drastic fluctuations in negative ion concentration, and the voltage transition time is extended to the symptom adaptation period, replacing sudden increases and decreases with gradual concentration changes. This operation reduces the risk of allergen exposure through compression interval and limiting control, and uses the extended transition time to allow the patient's mucous membrane or skin to gradually adapt to changes in negative ion concentration, thereby avoiding sneezing, rashes or itching caused by concentration step stimulation, and ultimately improving the user's physical tolerance while purifying the environment.

[0087] Preferably, the release medium is installed on the top, side and bottom of the bedside table respectively, and the first control module includes:

[0088] When the health tag includes a space-sensitive identifier and the air humidity exceeds a preset humidity threshold, the following operations are performed:

[0089] Analyze the user's taboo direction based on the historical trigger records of the space-sensitive identifier and the current air humidity distribution characteristics;

[0090] closing at least one medium release branch directly associated with the somatic discomfort area marked with the symptom type in the taboo direction;

[0091] Activate the remaining release medium branches in the taboo directions that are far away from the user activity hotspots and where the air humidity is lower than the safety threshold, and limit the number of connections in each direction to not exceed the preset connection upper limit of the corresponding direction.

[0092] In one embodiment, when the user's health tag has a "left-side space sensitive flag" (historical trigger records show that the body movement is abnormal when the left humidity is greater than 70%), and the left air humidity is detected to be 75% (the preset threshold is 65%), the first control module interprets the left side as a taboo direction, closes the top (humidity 80%) and middle (humidity 78%) release medium branches (a total of 2 branches) of the direction, to avoid the accumulation of negative ions in the high humidity area to stimulate the left shoulder marked with the "periarthritis of the shoulder" symptom; activates the left bottom medium (humidity 68% < safety threshold 70%), and increases its voltage from -8kV to -10kV (corresponding to a concentration of 1200ions / cm 3 ) and prevent electric field overload by limiting the number of connections (maximum 2 on the left, 1 actually activated); at the same time, set the bottom electric field weight to 1.5 times, guiding negative ions to diffuse to the user activity area on the right, so that the concentration on the right reaches 900ions / cm 3(Only 300ions / cm on the left 3 This operation, through the switching of prohibited media, compensatory boosting of safe media, and directional distribution of the electric field, avoids high humidity stimulation on the left side while maintaining an effective purification concentration in the active area on the right, achieving spatially differentiated control of the symptom-sensitive period.

[0093] Preferably, the release medium is installed on the top, side and bottom of the bedside table respectively, and the first control module includes:

[0094] When the symptom type is labeled as respiratory disease and the health label includes a respiratory sensitivity area, perform the following operations:

[0095] Determine the negative ion diffusion taboo direction based on the distribution density of the air humidity in each area of the bedside table and the geometric position of the respiratory sensitive area;

[0096] In the forbidden orientation, closing at least half of the release medium branches associated with abnormal fluctuations in the respiratory rate in the user's real-time physiological status indicator;

[0097] Activate the release medium branch in the direction of the air humidity gradient decrease in the taboo direction, and adjust the number of activated branches according to the symptom relief cycle.

[0098] When the user's symptom type is marked as asthma, and the health label includes the top proximal respiratory sensitive area, the air humidity at the top of the bedside table is detected to be 85%, 65% on the right side, and 70% at the bottom. The first control module identifies the top as a taboo position for negative ion diffusion based on the overlap of the high humidity distribution at the top and the geometric position of the respiratory sensitive area (the user's head is within 20 cm of the top). The system closes 4 of the 6 release medium branches at the top, which are associated with abnormal fluctuations in the user's real-time respiratory rate (such as more than 22 times per minute); at the same time, it activates one branch in the direction of the humidity gradient decrease (towards the bottom 70% area) of the remaining 2 branches at the top, and gradually adjusts the number of activated branches to 2 according to the remaining time of the symptom relief cycle (the preset cycle is 7 days, 3 days remaining, and the ratio is 42.8%). By closing the high humidity area branch in the taboo position, the negative ion concentration at the top increases from 1500ions / cm 3 Down to 600ions / cm 3 , while the activated bottom branch maintains 800ions / cm 3 Concentration, while blocking the stimulation of sensitive parts, gradually restores the purification coverage as the relief cycle progresses, and realizes progressive control of symptom adaptation.

[0099] In general, when the user has a respiratory disease and the respiratory sensitive area overlaps with the high humidity area, the system analyzes the humidity distribution in the bedside table and the geometric position of the sensitive area, closes the release medium branch in the taboo direction (i.e., interrupts the connection between the release medium and the high-voltage package), and blocks the respiratory stimulation caused by the combination of the high humidity environment and negative ions; activates the medium branch in the direction of the humidity gradient to maintain the basic purification capacity, and gradually increases the number of activated branches according to the symptom relief cycle, gradually restoring the purification coverage. Through the on-off control and directional activation adjustment of the taboo direction branch, the local irritation source is preferentially suppressed during the sensitive period, and the relief progress is dynamically adapted to balance the purification needs, which not only avoids the aggravation of abnormal fluctuations in respiratory rate in the acute period, but also ensures the sustainable recovery of environmental purification efficiency.

[0100] Preferably, the second control module includes:

[0101] When abnormal fluctuations in the user's heart rate or breathing rate are detected in the user's real-time physiological status indicators, the following actions are performed:

[0102] According to the amplitude of the abnormal fluctuation, the emergency adjustment level of the negative ion release frequency is divided, and the release medium branch associated with the position closest to the user's current body position is preferentially closed;

[0103] Based on the real-time relative position of the bedside table and the user, the electric field excitation timing of the remaining release medium is redistributed, so that the release frequency of the medium branch outside the preset safe distance from the user's body surface is increased;

[0104] If the indoor light intensity is lower than the circadian rhythm threshold and the weather data is marked as calm wind, the excitation interval of the high-frequency release medium will be extended until the user's physiological state indicators return to the preset safe range.

[0105] If the user's real-time heart rate is detected to be 112 beats per minute, exceeding the preset safety threshold of 90 beats per minute, the second control module determines that the abnormal fluctuation amplitude has reached the third emergency adjustment level and prioritizes shutting down the three release medium branches associated with the top of the bedside table, where the user's head is currently resting in the supine position. Based on the real-time position detection that the user's head is 15 cm from the top medium, less than the preset safety distance of 30 cm, the second control module reallocates the electric field excitation timing of the remaining side and bottom mediums, increasing the release frequency of the bottom medium branch 35 cm from the user's body surface from 2 to 5 times per second. At this time, the indoor light intensity is detected to be 40 lux, which is lower than the circadian rhythm threshold of 50 lux, and the weather data indicates calm wind conditions. The system then extends the excitation interval of the bottom high-frequency release medium from 5 times per second to 1 every 3 seconds, continuously monitoring until the user's heart rate returns to 88 beats per minute, entering the safe range. By shutting down the proximal medium to reduce local stimulation, improving the frequency compensation and purification efficiency of the distal medium, and suppressing potential interference from high-frequency release in low-light and calm wind environments, adaptive safety regulation is achieved during periods of abnormal physiological fluctuations.

[0106] Preferably, the second control module includes:

[0107] When an abnormal heart rate or breathing rate is detected in the user's real-time physiological status indicators, the following actions are performed:

[0108] Determining the avoidance priority of the negative ion action direction according to the extent to which the abnormal indicator deviates from the preset safety interval;

[0109] Based on the real-time relative position of the bedside table and the user, the side orientation and the release medium branch at the bottom of the bedside table are activated to form a surrounding electric field distribution;

[0110] If the wind force level in the weather data is higher than the preset wind force value, the electric field phase difference of the activation medium branch is adjusted to guide the negative ions to diffuse in the opposite direction of the wind force;

[0111] When the indoor light intensity is lower than the circadian rhythm threshold, the electric field intensity gradient of the release medium at the bottom is enhanced, so that negative ions are enriched in the low-light area away from the user's body surface.

[0112] In one embodiment, when the user's real-time heart rate is detected to be 128 beats per minute, exceeding the preset safety threshold of 100 beats per minute, the second control module determines the deviation amplitude to be 28% and determines the avoidance priority of the negative ion action direction to be level one, giving priority to avoiding the area on top of the bedside table where the user's head is currently in a side-lying position. Based on the real-time position detection of the user's head being 10 cm from the top, 50 cm from the side, and 60 cm from the bottom, the system activates four side and four bottom release medium branches, forming a surround electric field distribution covering the user's torso and lower limbs. At this time, the weather data shows that the wind force level is level 4, exceeding the preset level 3 threshold. The system adjusts the electric field phase difference of the activated branch to 120 degrees, guiding the negative ions to diffuse in the southeast direction against the wind. At the same time, it detects that the indoor light intensity of 30 lux is lower than the circadian rhythm threshold of 50 lux, and enhances the electric field intensity gradient at the bottom from 5 kV / m to 8 kV / m, causing the negative ion enrichment concentration in the low-light area under the bed to increase to 1200 ions / cm 3 , the concentration near the user's body surface is reduced to 400ions / cm 3 By avoiding proximal stimuli, surrounding electric field compensation purification, and environmental adaptation guidance, effective purification is maintained at a safe distance during periods of abnormal heart rate, reducing the risk of interference from high winds and low light.
