Description

Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to a bedside table with negative ion purification function and its working method. Background Technology

[0002] With the increasing demand for healthy homes, the functional limitations of traditional bedside tables and the technological bottlenecks of independent air purifiers are becoming increasingly apparent. Existing filter-based purifiers rely on physical interception mechanisms, resulting in problems such as filtration efficiency limited by static matching of filter pore size, high costs from frequent replacements, and noise interference from the fan. While conventional negative ion devices offer the advantage of being consumable-free, their release concentration, direction, and frequency are fixed, making it impossible to adaptively adjust based on dynamic environmental parameters (such as sudden humidity changes and differences in day and night light) or personalized health needs (such as respiratory sensitivity thresholds and allergen distribution). Especially in medical settings, existing technologies struggle to integrate real-time physiological indicators (such as abnormal heart rate fluctuations and respiratory rate irregularities), 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 user comfort, and even exacerbating symptoms due to uncontrolled ion concentration. These shortcomings indicate an urgent need to address the challenge of synergistic optimization of environmental adaptability, health safety, and purification efficiency in traditional technologies through multimodal data fusion and dynamic control mechanisms. Summary of the Invention

[0003] To address the aforementioned shortcomings, the present invention aims to provide a bedside table with negative ion purification function and its working method, thereby solving the problem of adaptability to 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 multi-parameter coordinated regulation.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A bedside table with negative ion purification function, the bedside table includes an environmental 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 transformer and several release media. The high-voltage transformer is used to output different voltages to different release media in order to provide the high-voltage electric field required for ionization.

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

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

[0010] The second control module is used to control the negative ion release frequency and direction of the negative ion generator based on the user's real-time physiological state 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 label includes a respiratory sensitivity indicator and the current indoor air humidity exceeds a preset humidity threshold, perform the following operations:

[0013] The safe range of negative ion concentration corresponding to the respiratory sensitivity indicator is analyzed, and the step adjustment level of the high voltage transformer voltage is divided according to the degree of deviation of the current indoor air humidity from the preset humidity threshold.

[0014] If the symptom type is labeled as a cold-related illness, then perform the following operations:

[0015] The body temperature-related threshold in the medical parameters corresponding to the cold-like disease is analyzed. When the user's real-time body temperature exceeds the body temperature-related threshold, several adjustment stages are divided according to the degree of temperature exceedance. Each stage corresponds to the increment and duration of the high voltage transformer voltage.

[0016] During the first adjustment phase, the voltage of the high-voltage transformer is increased according to the step adjustment level corresponding to the degree of humidity deviation, and maintained for a first preset duration.

[0017] If the body temperature continues to exceed the standard and the symptom relief period has not ended, the next adjustment phase will begin. The increment of the high voltage transformer will be reduced proportionally to the remaining time of the symptom relief period, and the duration will be extended to the second preset duration.

[0018] Preferably, the first control module includes:

[0019] If the described symptom type is labeled as allergic rhinitis or skin disease, then perform the following operations:

[0020] The allergen identifiers recorded in the health label are analyzed, the environmental triggering conditions of the corresponding allergens are analyzed, and the fluctuation range of the negative ion concentration safe range is compressed according to the environmental triggering conditions.

[0021] When the air humidity or indoor light intensity meets the environmental triggering conditions, the adjustment range of the high-voltage transformer voltage is limited to half of the compressed range, and the voltage transition time is extended to the preset symptom adaptation period.

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

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

[0024] Based on the historical trigger records of the spatially sensitive identifier and the current air humidity distribution characteristics, the user's forbidden directions can be analyzed;

[0025] Close at least one release medium branch within the contraindicated location that is directly associated with the area of ​​somatic discomfort marked by the symptom type;

[0026] Activate the remaining release medium branches in the forbidden directions that are far from user activity hotspots and have air humidity below the safety threshold, and limit the number of connections in each direction to no more than the preset connection limit for the corresponding direction.

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

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

[0029] Based on the distribution density of air humidity in different areas of the bedside table and the geometric location of the breathing-sensitive area, the forbidden direction for negative ion diffusion is determined.

[0030] Within the prohibited orientation, close at least half of the release medium branches associated with abnormal fluctuations in respiratory rate in the user's real-time physiological state indicators;

[0031] Activate the release medium branch in the direction of decreasing air humidity gradient in the forbidden location, 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 a user's real-time physiological indicators such as heart rate or respiratory rate are detected, perform the following actions:

[0034] The emergency adjustment level of the negative ion release frequency is determined according to the amplitude of the abnormal fluctuations, and the release medium branch associated with the nearest position to the user's current body position is closed first.

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

[0036] If the indoor light intensity is below the circadian rhythm threshold and the weather data is marked as calm, 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 abnormality is detected in the user's real-time physiological indicators, such as heart rate or respiratory rate, perform the following actions:

[0039] Based on the extent to which the abnormal indicators deviate from the preset safe range, the avoidance priority of the negative ion action direction is determined;

[0040] Based on the real-time relative position between the bedside table and the user, the side orientation and bottom release medium branches 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 phase difference of the electric field of the activated medium branch is adjusted to guide the negative ions to diffuse in the opposite direction of the wind.

[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, causing negative ions to accumulate in low-light areas away from the user's body surface.

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

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

[0045] Acquire user biometric data, which includes user physiological state indicators, health tags, and disease types;

[0046] Based on the air humidity, health label, and symptom type, control the negative ion release concentration and diffusion range of the negative ion generator;

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

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

[0049] This invention adjusts the negative ion concentration in real time based on air humidity, suppressing the problem of negative ion aggregation and failure in high humidity environments, while maintaining purification efficiency in low humidity scenarios. Combining weather data and indoor light intensity, it predicts airflow trends and diurnal rhythm needs, optimizing the negative ion diffusion path through phase difference adjustment and electric field gradient distribution, avoiding purification blind spots in calm or bright light environments. Based on user health tags (such as respiratory sensitivity indicators) and symptom types (such as asthma, allergies), it automatically identifies prohibited areas and shuts off high-risk release media, blocking the accumulation and stimulation of negative ions in sensitive areas. By activating safe all-around media and dynamically compensating for voltage, it maintains... It maintains the purification intensity in non-sensitive areas, achieving a spatial balance between local inhibition and global enhancement. When abnormal fluctuations in heart rate or respiratory rate are detected, it prioritizes shutting down the proximal release medium to reduce the risk of immediate stimulation, while simultaneously increasing the release frequency or electric field intensity of the distal release medium to directionally compensate for purification capacity. It optimizes the surrounding electric field distribution based on the user's body position and relative location to ensure that the direction of negative ion action is precisely matched with the user's activity hotspot area. Based on the symptom relief cycle, it dynamically adjusts the number of activated branches and the rate of voltage increase attenuation to gradually restore purification efficiency while ensuring the safety threshold in the acute phase, avoiding energy waste caused by long-term high-load operation.

[0053] Figure 3 This is a flowchart of the working method of the bedside table with negative ion purification function provided in the embodiment of the present invention;

[0054] Among them, release medium 1. Detailed Implementation

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

[0056] In this invention, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said 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 environmental monitoring module, a user monitoring module, a first control module, a second control module, and a negative ion generator. The environmental monitoring module, user monitoring module, first control module, second control module, and negative ion generator can be integrated into a bedside table system with negative ion purification function. Therefore, the systems mentioned below are all bedside table systems with negative ion purification function.

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

[0059] For the high-voltage transformer, 220V AC power can be used as the input. First, an EMC circuit suppresses electromagnetic interference, reducing its impact on the power supply and equipment. Then, a rectifier and filter circuit converts the AC power to DC power and filters out ripple, resulting in smooth DC power. This DC power then enters the switching power supply circuit, which stabilizes the output voltage and regulates the power, providing a suitable input for the transformer. The transformer then reduces the voltage, outputting 12V or other low-voltage power to the high-voltage transformer and other circuits, ensuring safe and stable operation of the equipment. Subsequently, the MCU control signal is transmitted to the transformer switching circuit, working in conjunction with the self-excited oscillation circuit to convert the low voltage to a negative high-voltage output of -5kV. This provides the necessary conditions for subsequent air ionization and the generation of negative charges, ultimately promoting the combination of negative charges and oxygen to form negative oxygen ions, achieving the effect of air purification.

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

[0061] Specifically, the purpose of the environmental monitoring module is to build a dynamic environmental information model so that the operating parameters of the negative ion generator can be precisely adjusted according to environmental conditions. For example, in a high-humidity environment, it may be necessary to adjust the negative ion release strategy to prevent negative ions from easily agglomerating and limiting the purification effect due to excessive humidity; indoor air quality and other environmental factors will also change under different weather and lighting conditions, and obtaining these parameters appropriately can provide a basis for subsequent personalized purification solutions.

[0062] Real-time weather data refers to the current weather conditions obtained through internet interfaces or external meteorological sensors, such as sunny, rainy, and hazy days. It reflects the potential impact of the outdoor environment on indoor air quality (e.g., ventilation during naps), thus affecting the negative ion purification strategy. Air humidity is an indicator of indoor air moisture content measured by a humidity sensor. It directly relates to the existence and migration ability of negative ions in the air. Too high humidity may cause negative ions to easily bind with water molecules, affecting the purification effect, while too low humidity may lead to dry air, affecting comfort and some purification reactions. Indoor light intensity is detected by a photosensitizer. Under different light intensities, the indoor environment changes. Light intensity is used to match the user's circadian rhythm (e.g., reducing the release intensity at night to avoid disturbing sleep).

[0063] For acquiring environmental parameters, one approach is to utilize Internet of Things (IoT) technology to obtain real-time weather data by connecting to the local meteorological service interface. Simultaneously, a humidity sensor and a light sensor built into the bedside table can measure air humidity and indoor light intensity in real time, respectively. This method can conveniently and quickly obtain accurate external weather information and combine it with internal environmental parameters to provide comprehensive data support for subsequent adjustments. Another approach is to rely solely on a simple environmental monitoring module built into the bedside table itself to periodically collect air humidity and light intensity data within a small surrounding area. This method is relatively low-cost and can be effective in scenarios where the indoor environment is relatively stable and the correlation with external weather is not critical.

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

[0065] Specifically, the user monitoring module can use various biological monitoring devices or health data interfaces to collect user biometric data such as physiological state indicators (e.g., heart rate, respiratory rate), health tags (e.g., tags indicating whether the user has respiratory diseases or other health conditions), and symptom types. The purpose is to achieve personalized air purification adjustment based on the user's own health status and real-time physiological state, so as to meet the different purification needs of different users due to health differences. For example, users with respiratory sensitivities need a more suitable concentration of negative ions and a purified environment.

[0066] User physiological status indicators refer to data obtained through wearable devices that reflect the user's current physical condition. For example, abnormal fluctuations in heart rate may indicate that the user is in a state of stress or discomfort, and disordered breathing rate may indicate respiratory problems. These indicators can directly reflect the user's immediate physical health status and the degree and direction of their urgent need for air purification. Health tags are a general label of the user's long-term health status, such as "allergic constitution" or "chronic bronchitis patient". This allows the system to understand the user's past health priorities so as to adjust the purification strategy in a long-term and targeted manner. Symptom types are the classification of the user's current specific symptoms, such as mucosal irritation caused by a cold or allergic rhinitis. Different symptoms correspond to different pathological mechanisms and sensitivities to the air environment, which can be used to accurately optimize the purification solution.

[0067] For the user monitoring module, one feasible approach is to interface with the user's smart wearable health bracelet or medical health monitoring device to obtain real-time physiological indicators such as heart rate and respiratory rate. Simultaneously, users can input their health tags and ailment types into a mobile app linked to the bedside table. This method integrates real-time physiological data with user-provided background health information, enabling the construction of a comprehensive and dynamic user health profile for subsequent precise adjustments. Another approach is to equip the bedside table with simple biosensors, such as heart rate sensors on the handles, to collect basic physiological data when the user touches it. This method can also obtain some real-time physiological information and is useful in scenarios where users use the device occasionally and have high privacy requirements. Combining the former comprehensive data integration with the latter simple self-monitoring ensures accurate and comprehensive acquisition of key data, while using simple self-monitoring as a supplement or emergency measure to further improve the collection of user biometric data. This allows the purification adjustment to better match the user's actual health changes, achieving a better personalized purification effect.

[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 symptom type;

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

[0070] The second control module is used to control the negative ion release frequency and direction of the negative ion generator based on the user's real-time physiological state 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 state indicators (which reflect the user's dynamic needs for air purification based on their immediate physical condition), the relative position of the bedside table and the user (to determine the optimal spatial directionality of negative ion action, i.e., considering the influence of distance and orientation on the path and effect of negative ions reaching key areas such as the user's breathing area), weather data (wind force, rainfall) to predict the impact of air flow on the diffusion of negative ions, and indoor light intensity (which may vary depending on the activity state of people and indoor ventilation under different lighting conditions; for example, strong sunlight and more user activity during the day may require purification assistance of different frequencies and directions). The release frequency is changed by adjusting the drive signal frequency of the negative ion generator, and the direction of action is changed by adjusting the orientation of the release medium or using guiding devices. The goal is to ensure that negative ions act on the areas around the user that need purification most at the right time and in the right direction, improving the timeliness and accuracy of purification. For example, in a calm environment, negative ions are guided to diffuse directionally towards the pollution source, replacing the passive interception mechanism of filter-type purifiers.

[0072] Preferably, the first control module includes:

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

[0074] The safe range of negative ion concentration corresponding to the respiratory sensitivity indicator is analyzed, and the step adjustment level of the high voltage transformer voltage is divided according to the degree of deviation of the current indoor air humidity from the preset humidity threshold.

[0075] If the symptom type is labeled as a cold-related illness, then perform the following operations:

[0076] The body temperature-related threshold in the medical parameters corresponding to the cold-like disease is analyzed. When the user's real-time body temperature exceeds the body temperature-related threshold, several adjustment stages are divided according to the degree of temperature exceedance. Each stage corresponds to the increment and duration of the high voltage transformer voltage.

[0077] During the first adjustment phase, the voltage of the high-voltage transformer is increased according to the step adjustment level corresponding to the degree of humidity deviation, and maintained for a first preset duration.

[0078] If the body temperature continues to exceed the standard and the symptom relief period has not ended, the next adjustment phase will begin. The increment of the high voltage transformer will be reduced proportionally to the remaining time of the symptom relief period, and the duration will be extended to the second preset duration.

[0079] Assuming a user's health label includes "asthma" (a respiratory sensitivity indicator), the safe range for negative ion concentration is 800-1500 ions / cm³. 3 When the detected indoor air humidity is 72% (preset threshold 60%, exceeding the standard by 12%), the first control module divides the humidity deviation into three levels, each 4% increment, for a total of three levels (12% ÷ 4%). Each level corresponds to a 1kV increase in the high-voltage transformer voltage (reference voltage -5kV → target -8kV, corresponding to a negative ion concentration of approximately 1100 ions / cm³). 3 Meanwhile, the user's symptom type was labeled "viral cold," the temperature-related threshold in the medical parameters was 37.5℃, and the real-time temperature was 38.2℃ (0.7℃ above the standard), triggering a phased adjustment: In the first phase, the voltage was increased to -8kV according to the humidity step scale and maintained for 30 minutes. At this time, the negative ion concentration reached 73% of the safe range (1100 / 1500). If the body temperature continued to exceed the standard and the symptom relief period had 4 days remaining (total period 7 days, remaining percentage 57%), the second phase began. The voltage increase was reduced to 57% of the original value (1kV / level × 57% ≈ 0.57kV / level), and the total increase was reduced to 1.71kV (-5kV → -6.71kV, rounded to -6.5kV), corresponding to a concentration of approximately 900 ions / cm³. 3 (Lower limit of the safe range), duration extended to 52 minutes; if still not relieved, the third stage voltage drops to -5.57kV (5kV + 0.57kV), and the concentration drops to 800 ions / cm³. 3 (Safety lower limit), duration extended to 90 minutes. Through a gradual increase and decrease of 1kV per level, rapid purification (1100 ions / cm³) is achieved at -8kV in the initial stage of excessive humidity. 3 When body temperature is abnormal, it gradually converges to the safe lower limit (900→800 ions / cm). 3 To balance the need for sudden environmental purification with long-term symptom tolerance through a gentler concentration gradient.

[0080] In summary, when excessive air humidity is detected, the system automatically adjusts the voltage in stages, progressively increasing the voltage of the high-voltage transformer according to the degree of humidity deviation. This ensures that the negative ion concentration remains within a 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 increase in body temperature. In the initial stage, the voltage is increased according to humidity requirements to maintain basic purification efficiency. If the body temperature remains abnormal, the voltage increase is dynamically reduced and the duration of action is extended according to the symptom relief cycle, gradually converging the negative ion concentration to a safe lower limit to prevent high-concentration release from causing mucosal dryness or immune overload. Through the synergistic effect of humidity-driven concentration gradient regulation and temperature-triggered dynamic attenuation mechanism, local irritation is suppressed in respiratory sensitive scenarios, and purification needs and physiological tolerance are balanced during cold and fever periods, achieving a dual adaptation of safety and response to sudden environmental changes.

[0081] Furthermore, the first control module includes:

[0082] If the described symptom type is labeled as allergic rhinitis or skin disease, then perform the following operations:

[0083] The allergen identifiers recorded in the health label are analyzed, the environmental triggering conditions of the corresponding allergens are analyzed, and the fluctuation range of the negative ion concentration safe range is compressed according to the environmental triggering conditions.

[0084] When the air humidity or indoor light intensity meets the environmental triggering conditions, the adjustment range of the high-voltage transformer voltage is limited to half of the compressed range, and the voltage transition time is extended to the preset symptom adaptation period.

[0085] For example, when a user's symptom type is labeled as "dust mite allergic rhinitis," and the allergen recorded in the health label is "dust mite," and the environmental triggering conditions are analyzed to be humidity ≥70% or light intensity ≥500 lux, the first control module will adjust the original negative ion concentration to the safe range (1000-5000 ions / cm³). 3 Compress to 1200-3000 ions / cm³ 3 (Fluctuation range reduced by 60%). When the current air humidity is detected to be 75% (trigger humidity condition), the high-voltage transformer voltage adjustment range is limited to half of the compressed range (e.g., ±900 ions / cm). 3 The corresponding voltage is ±1.8kV. The adjustment range of the reference voltage -5kV is limited to -3.2kV ​​to -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 magnitude of voltage abrupt changes (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), allows the patient's nasal mucosa to gradually adapt to changes in negative ion concentration, avoiding sneezing or skin itching caused by sudden concentration changes.

[0086] In summary, in this embodiment, when the user's symptoms are allergic rhinitis or skin disease, the fluctuation range of the safe range of negative ion concentration is compressed by analyzing the environmental triggering conditions (such as humidity or light threshold) corresponding to the allergen identifier, thus suppressing the risk of runaway high-concentration negative ions in specific environments. When the environmental parameters are detected to meet the triggering conditions, the adjustment range of the high-voltage pack voltage is limited to half of the compressed range to prevent voltage mutations from causing drastic fluctuations in negative ion concentration. 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 range compression and amplitude limiting control. At the same time, the extended transition time allows the patient's mucous membranes or skin to gradually adapt to changes in negative ion concentration, avoiding sneezing, rashes, or itching caused by concentration step stimulation. Ultimately, the user's physical tolerance is improved while purifying the environment.

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

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

[0089] Based on the historical trigger records of the spatially sensitive identifier and the current air humidity distribution characteristics, the user's forbidden directions can be analyzed;

[0090] Close at least one release medium branch within the contraindicated location that is directly associated with the area of ​​somatic discomfort marked by the symptom type;

[0091] Activate the remaining release medium branches in the forbidden directions that are far from user activity hotspots and have air humidity below the safety threshold, and limit the number of connections in each direction to no more than the preset connection limit for the corresponding direction.

[0092] In one embodiment, when the user's health tag has a "left-side space sensitivity indicator" (historical trigger records show abnormal body movement when left-side humidity > 70%), and the detected left-side air humidity is 75% (preset threshold 65%), the first control module interprets the left side as a forbidden direction, closes the top (humidity 80%) and middle (humidity 78%) release medium branches (two in total) in this direction, to prevent the accumulation of negative ions in the high-humidity area from stimulating the left shoulder marked with "frozen shoulder" symptoms; activates the left-side bottom medium (humidity 68% < safety threshold 70%), increasing its voltage from -8kV to -10kV (corresponding to a concentration of 1200 ions / cm³). 3 It also prevents electric field overload by limiting the number of connections (maximum of 2 on the left, with 1 actually active); at the same time, it sets the bottom electric field weight to 1.5 times to guide the negative ions to diffuse towards the user's activity area on the right, so that the concentration on the right reaches 900 ions / cm³. 3(On the left side, only 300 ions / cm) 3 This operation, through the switching on and off of the medium in the forbidden direction, the voltage boosting of the safe medium, and the directional distribution of the electric field, avoids the stimulation of high humidity on the left side while maintaining the effective purification concentration in the active area on the right side, thus achieving spatially differentiated control during the sensitive period of symptoms.

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

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

[0095] Based on the distribution density of air humidity in different areas of the bedside table and the geometric location of the breathing-sensitive area, the forbidden direction for negative ion diffusion is determined.

[0096] Within the prohibited orientation, close at least half of the release medium branches associated with abnormal fluctuations in respiratory rate in the user's real-time physiological state indicators;

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

[0098] When the user's symptom type was tagged as asthma, and the health tag included the top proximal respiratory sensitive area, the detected air humidity was 85% at the top of the bedside table, 65% on the right side, and 70% at the bottom. The first control module, based on the overlap between the high humidity distribution at the top and the geometric location of the respiratory sensitive area (within 20 cm of the user's head near the top), identified the top as a forbidden area for negative ion diffusion. The system shut down 4 of the 6 release medium branches at the top, these branches being associated with abnormal fluctuations in the user's real-time respiratory rate (e.g., exceeding 22 breaths per minute); simultaneously, it activated 1 of the remaining 2 branches at the top, in the direction of decreasing humidity gradient (towards the bottom 70% area), and gradually adjusted the number of activated branches to 2 based on the remaining time of the symptom relief cycle (preset cycle 7 days, 3 days remaining, proportion 42.8%). By shutting down the branch in the forbidden high-humidity area, the negative ion concentration at the top decreased from 1500 ions / cm³. 3 Reduced to 600 ions / cm 3 The activated basal branches maintain 800 ions / cm 3 The concentration, while blocking stimulation in sensitive areas, gradually restores the purification coverage as the relief cycle progresses, achieving progressive control adapted to symptoms.

[0099] In summary, when a user has respiratory illnesses and their respiratory sensitivity area overlaps with a high-humidity area, the system analyzes the humidity distribution and geometric location of the sensitive area around the bedside table. It then shuts down the release medium branches in prohibited areas (i.e., interrupts the connection between the release medium and the high-voltage pack), blocking respiratory irritation caused by the combination of high humidity and negative ions. The system activates medium branches along the direction of decreasing humidity gradient to maintain basic purification capacity, and gradually increases the number of activated branches according to the symptom relief cycle, progressively restoring the purification coverage. Through the control of the on / off state of branches in prohibited areas and targeted activation adjustment, the system prioritizes suppressing local irritants during sensitive periods while dynamically adapting to the progress of symptom relief to balance purification needs. This avoids exacerbating abnormal fluctuations in respiratory rate during acute phases and ensures the sustainable recovery of environmental purification efficiency.

[0100] Preferably, the second control module includes:

[0101] When abnormal fluctuations in a user's real-time physiological indicators such as heart rate or respiratory rate are detected, perform the following actions:

[0102] The emergency adjustment level of the negative ion release frequency is determined according to the amplitude of the abnormal fluctuations, and the release medium branch associated with the nearest position to the user's current body position is closed first.

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

[0104] If the indoor light intensity is below the circadian rhythm threshold and the weather data is marked as calm, 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] When 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 has reached the level of Level 3 emergency adjustment. It prioritizes shutting down the three release medium branches associated with the top of the bedside table, which is in close contact with the user's head in their current supine position. Based on the real-time location detection that the distance between the user's head and the top medium is 15 cm, less than the preset safety distance of 30 cm, the system reallocates the electric field excitation sequence of the remaining side and bottom mediums, increasing the release frequency of the bottom medium branch (35 cm away from the user's body surface) from 2 times per second to 5 times per second. At this time, the indoor light intensity is detected at 40 lux, below the circadian rhythm threshold of 50 lux, and the weather data indicates a calm wind. The system extends the excitation interval of the bottom high-frequency release medium from 5 times per second to 1 time per 3 seconds, continuously monitoring until the user's heart rate drops back to 88 beats per minute, entering the safe range. By shutting down the proximal medium to reduce local stimulation, increasing the frequency compensation 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 abnormality is detected in the user's real-time physiological indicators, such as heart rate or respiratory rate, perform the following actions:

[0108] Based on the extent to which the abnormal indicators deviate from the preset safe range, the avoidance priority of the negative ion action direction is determined;

[0109] Based on the real-time relative position between the bedside table and the user, the side orientation and bottom release medium branches 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 phase difference of the electric field of the activated medium branch is adjusted to guide the negative ions to diffuse in the opposite direction of the wind.

[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, causing negative ions to accumulate in low-light areas 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 that the deviation is 28% and sets the priority for avoiding the negative ion effect direction to level one, prioritizing avoiding the area above the bedside table where the user's head is currently in a side-lying position. Based on real-time location detection, the distance between the user's head and the top is 10 cm, the side is 50 cm, and the bottom is 60 cm. Four release medium branches on the side and four on the bottom are activated, forming a surrounding electric field distribution covering the user's torso and lower limbs. At this time, the wind force level in the weather data is level 4, exceeding the preset level 3 threshold. The system adjusts the phase difference of the electric field in the activated branches to 120 degrees, guiding the negative ions to diffuse against the wind in the southeast direction. At the same time, the indoor light intensity of 30 lux is detected, which is lower than the circadian rhythm threshold of 50 lux. The electric field intensity gradient at the bottom is increased from 5 kV / m to 8 kV / m, increasing the concentration of negative ions in the low-light area under the bed to 1200 ions / cm². 3 The concentration near the user's body surface dropped to 400 ions / cm³. 3 By avoiding near-end irritants, using surrounding electric field compensation for purification, and guiding environmental adaptation, 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.
