Description

Technical Field

[0001] The invention relates to the technical field of disinfection, in particular to a disinfection, sterilization and purification pipeline system. Background Art

[0002] With the increasing frequency of use of disinfection rooms, the management of indoor air quality and surface hygiene has become an important factor affecting public environmental hygiene. At present, in the existing technology, a combination of fixed-frequency disinfectant spraying, ultraviolet sterilization and air purification equipment is often used to disinfect and purify the disinfection room. These technical solutions can improve the bathroom environment to a certain extent by treating particulate matter, germs and odors in specific areas. For example, static filtration technology combined with ultraviolet germicidal lamps can kill suspended particles and some microorganisms in the air; fixed-frequency disinfectant spraying equipment performs basic treatment on surface viruses and bacteria. During continuous use, these solutions play an important role in maintaining the basic cleanliness of the bathroom and reducing the risk of germ transmission.

[0003] The Chinese invention patent with announcement number CN108488935B discloses a temperature and humidity regulated filtering and sterilizing air supply device, which realizes the comprehensive treatment of filtering, humidifying, heating, sterilizing and filtering the blown fresh air by passing the external air through the air inlet filter, air filter, spray humidification chamber, electric heating wire cylinder, sterilization chamber, air supply filter cylinder and high-temperature filter in sequence and discharges it from the exhaust port, thus solving the problem that the traditional fresh air blower directly blows the external air into the room without effective treatment, resulting in the deterioration of indoor air quality. Although the scheme optimizes the humidification, heating and sterilization functions in the air purification process, its limitations still exist, especially in terms of responsiveness in dynamic environments and optimization of resource utilization.

[0004] Although existing technologies have achieved basic treatment of air and surface hygiene, there is still room for improvement in dynamic adjustment and resource utilization efficiency. Most solutions lack real-time monitoring and feedback mechanisms, and are unable to make intelligent adjustments based on real-time changes in the flow of people and air quality in the bathroom, resulting in waste of resources or insufficient coverage. In addition, most existing technologies adopt independent modular designs, which cannot achieve the linkage optimization of disinfection and purification modules, and do not recycle unused disinfectants, resulting in a prominent waste of resources. Finally, due to the lack of monitoring of operating status and storage of historical data, it is difficult to evaluate the effects and optimize functions of the system during long-term operation.

[0022] Specifically, the dynamic monitoring module is used to collect real-time data on air quality and crowd density in the disinfection room, and provide data support for the operation of the spray disinfection module and the air purification module. This module plays a key monitoring and feedback role in the overall workflow of the system, and is closely connected with subsequent modules through distributed sensor layout and intelligent data processing technology. In the spray disinfection module, its output data determines the spraying dosage and frequency of the disinfectant; in the air purification module, the collected air quality parameters serve as an important basis for adjusting the purification intensity and operating status. Through the dynamic monitoring module, the environmental status of the bathroom can be grasped in real time to ensure the efficient operation of the system and the rational allocation of resources.

[0023] In this embodiment, the dynamic monitoring module includes an air quality monitoring unit and a crowd flow monitoring unit, which are responsible for collecting air parameters and crowd flow density data in the toilet respectively.

[0024] Generally, the air quality monitoring unit monitors the air in the bathroom in multiple dimensions through a distributed layout. Specifically, it includes the following sensor devices: PM2.5 sensor is used to detect the concentration of particulate matter in the air. The sensor works based on the principle of light scattering. It emits a laser beam and measures the scattering intensity of light by particles to obtain the concentration value of particles. The measurement range is generally 0 to 1000 micrograms per cubic meter, with an accuracy of ±1 microgram per cubic meter.

[0025] VOC sensor is used to monitor the concentration of volatile organic compounds in the air. As an option, the VOC sensor uses semiconductor gas sensitive materials to determine the concentration of organic compounds through changes in conductivity. The concentration unit is ppm (parts per million).

[0026] Temperature and humidity sensor, used to collect temperature and humidity data in the bathroom. The temperature measurement range is -40℃~125℃, and the humidity measurement range is 0%RH~100%RH.

[0027] Carbon dioxide (CO 2) sensor is used to monitor the concentration of carbon dioxide in the air. The sensor is usually based on the principle of infrared light absorption. By detecting the attenuation of light of a specific wavelength, the carbon dioxide concentration value is obtained. The concentration range is 0ppm to 5000ppm.

[0028] In some embodiments, the above-mentioned sensors are installed near the top and walls of the bathroom to form a distributed layout, ensuring that the measurement range covers the main areas of the bathroom.

[0029] After data collection, the analog signal is converted into a digital signal through the analog-to-digital conversion module inside the sensor, and the data is sent to the central controller of the intelligent control module through the wireless transmission module. Specifically, the data transmission frequency can be set from 1 to 10 times per second, and the specific frequency is adjusted according to the real-time requirements of the system.

[0030] In a possible implementation, the normalization formula for air quality data is as follows: in: C norm (t): normalized air quality parameter, ranging from 0 to 1; C(t): the raw data value collected by the sensor in real time; C min and C max :The lower and upper limits of the safe range of air quality parameters are set according to the bathroom design requirements.

[0031] The normalized data is input into the intelligent control module for dynamic adjustment of spraying and purification operations.

[0032] In this embodiment, the crowd flow monitoring unit is installed at the entrance of the toilet, and real-time crowd flow monitoring is achieved by combining an infrared sensor and a smart camera.

[0033] Infrared sensors are generally based on the infrared pyroelectric principle, detecting changes in infrared radiation when a person passes through, and counting the number of people entering and leaving. Each triggering of the infrared radiation signal is counted as one person, and the number of people entering and leaving is accumulated through the counter to obtain the current flow of people in the bathroom.

[0034] As an option, smart cameras can be combined with edge computing technology to track and analyze the flow of people to further optimize the accuracy of crowd density data. The camera identifies the number of people through a dynamic target detection algorithm and calculates the crowd density based on the entrance area: in: ρ(t): real-time crowd density, in people per square meter; N current(t): The current number of people in the bathroom, counted by the infrared sensor and the smart camera; A area : The total area of ​​the bathroom, in square meters.

[0035] In a possible implementation, the data refresh rate of the crowd monitoring unit is 2 times per second, and the refresh result is sent to the central controller via a wireless network and processed synchronously with the air quality data.

[0036] In some embodiments, the dynamic monitoring module may also include a noise sensor and an ammonia sensor. The noise sensor is used to measure the ambient noise level in the bathroom, with a monitoring range of 20 to 120 decibels. The ammonia sensor can be used to detect the ammonia concentration in the air, with a concentration range of 0ppm to 100ppm. These data can be used as additional parameters to help further optimize the disinfection and purification logic of the system.

[0037] In addition, in the process of implementing the dynamic monitoring module, the layout and installation method of the sensor can be flexibly adjusted according to the structural characteristics of the bathroom. For example, the top sensor is suitable for bathrooms with larger areas, while the wall sensor is suitable for smaller bathroom spaces. The protection level of the sensor is generally designed to be IP65 to ensure that it can work normally in a high humidity environment.

[0038] The spray disinfection module is a key functional unit of the present invention, and its main task is to carry out comprehensive disinfection of the air and surface areas in the disinfection room. This module realizes precise spraying through the regulation of the intelligent control module based on the real-time data provided by the dynamic monitoring module, combined with air quality parameters and crowd density. This module combines electrochemical disinfectant generation technology with high-efficiency ultrasonic atomization technology, which can not only generate highly effective bactericidal disinfectant in real time, but also evenly atomize the disinfectant into the air and surface areas. This module works in conjunction with the air purification module to improve the overall air quality while disinfecting.

[0039] In this embodiment, the spraying and disinfection module mainly includes an electrochemical disinfectant generating device, a delivery pipeline and a plurality of high-frequency ultrasonic atomizing nozzles.

[0040] Generally, electrochemical disinfectant generation devices generate sodium hypochlorite (NaClO) solution by electrolyzing water and sodium chloride (NaCl). As a broad-spectrum, highly effective bactericide, sodium hypochlorite can quickly kill bacteria and viruses in the air while having good safety.

[0041] Specifically, the electrolyzer is the core component of the disinfectant generation device. The electrolyzer decomposes water into hydrogen and oxygen through direct current, and reacts with sodium chloride to produce sodium hypochlorite. As an option, the electrolyzer can use bipolar membrane electrolysis technology, and through the separation design of the anode chamber and the cathode chamber, it can avoid the mixing of by-products and improve the purity of sodium hypochlorite.

[0042] As an option, a liquid level sensor is installed in the electrolytic cell to monitor the liquid inventory in real time. When the liquid level is lower than the set minimum value, the liquid automatic replenishment device is activated to replenish water and sodium chloride solution to maintain the continuity of the reaction.

[0043] After the disinfectant is generated, it is delivered to multiple nozzles through a delivery pipeline. A flow control device can be configured at the outlet of the pipeline to adjust the liquid flow rate and prevent liquid waste.

[0044] In this embodiment, the nozzle adopts high-frequency ultrasonic atomization technology. The ultrasonic nozzle converts the liquid into micron-sized droplets through high-frequency vibration, achieving suspension in the air and comprehensive coverage of the surface. Generally, the vibration frequency range of the nozzle is between 20-40kHz, and the higher the vibration frequency, the smaller the droplet size.

[0045] Specifically, the droplet size is inversely proportional to the vibration frequency. The droplet diameter can be approximately calculated using the following formula: in: D drop : average diameter of atomized droplets; μ: viscosity of disinfectant; Q: Liquid flow rate; d: nozzle diameter; v: injection velocity.

[0046] In one possible implementation, the particle size range of the nozzle can be controlled within 1 to 5 microns, ensuring that the droplets can be evenly distributed and suspended in the air for a long time. At the same time, the nozzles are arranged on the top, walls and floor areas of the disinfection room. The top nozzle is used to disinfect particulate matter and viruses in the air, the wall nozzle is used to treat droplets and suspended matter, and the floor nozzle is used to disinfect the ground surface.

[0047] As an option, the spraying strategy of the spraying disinfection module in the present invention is dynamically adjusted by the intelligent control module based on air quality data and crowd density. The calculation formula of the spraying amount is as follows: V spray (t) = k 1 ·ρ(t)+k 2 ·[1-C norm (t)] in: Vspray (t): spraying amount at time t; ρ(t): crowd density at time t, in people per square meter; C norm (t): normalized air quality parameter; k 1 , k 2 : Adjustment coefficient, used to control the weight of the impact of crowd density and air quality on the spraying amount.

[0048] Generally speaking, when the crowd density is high, the system will increase the spraying volume to improve disinfection efficiency; when the air quality parameters are close to the good range, the spraying volume will automatically decrease to save resources.

[0049] In some embodiments, the spray disinfection module may further include a heating spray device for increasing the temperature of the liquid and improving the activity of the disinfectant. In a low temperature environment, the heating device may heat the liquid to 30°C to 50°C through an electric heating wire to enhance the sterilization effect.

[0050] As a possible option, the spraying area can be optimized based on the hot spots of human traffic. For example, through the heat map provided by the dynamic monitoring module, the spraying system can prioritize the disinfection of areas with high human traffic density.

[0051] In addition, this module also supports linkage operation with the air purification module. For example, when the air purification module detects a high concentration of particulate matter in the air, the spraying module can also increase the amount of disinfectant sprayed, further improving the overall effect.

[0052] The spraying and disinfection module relies on the real-time data provided by the dynamic monitoring module. The output data of the air quality sensor and the crowd monitoring unit in the dynamic monitoring module directly affect the calculation of the spraying amount and the adjustment of the spraying frequency. Through the intelligent control module, the spraying and disinfection module can receive control instructions in real time and coordinate with the air purification module and resource management module to ensure the efficient operation of the entire system.

[0053] The output of the spray disinfection module will also affect the working status of the resource management module. For example, the disinfectant that is not completely atomized is returned to the disinfectant generation device through the recovery pipeline, thus realizing closed-loop management.

[0054] The air purification module is used to deeply purify the air in the disinfection room. This module works closely with the dynamic monitoring module and the spray disinfection module to jointly ensure the safety and stability of indoor air quality. The air quality parameters provided by the dynamic monitoring module are directly used to control the operating status of the air purification module, and the spray disinfection module further improves the air environment by cooperating with this module. This module adopts a modular design, and can meet the needs of different bathroom areas and air quality through flexible configuration. It combines high-efficiency filtration, sterilization and dynamic airflow guidance technology to provide comprehensive air purification capabilities for the entire system.

[0055] In this embodiment, the air purification module mainly includes a modular purification unit, a dynamic airflow guiding device and a ventilation device.

[0056] Generally, modular purification units are composed of multiple functional components, each of which processes different pollutants in the air. Specifically, they include the following components: High efficiency filter, used to capture particulate matter in the air (such as PM2.5). The filter is made of multi-layer composite material and can effectively remove particles with a diameter of 0.3 microns and above. The filtration efficiency reaches 99.97%.

[0057] Activated carbon filters are used to absorb odors and volatile organic compounds (VOCs) in the air. Activated carbon filters have a high specific surface area and their adsorption capacity is described by the following formula: Q ads =K·P n in: Q ads : The adsorption capacity of activated carbon, in milligrams; K: adsorption constant related to the specific surface area of ​​activated carbon; P: partial pressure of adsorbed gas, in Pascals; n adsorption index, usually between 0.5 and 1 Ultraviolet germicidal lamps are used to kill microorganisms in the air. Ultraviolet lamps operate at a wavelength of 254 nanometers and can destroy the DNA or RNA structure of bacteria and viruses to achieve an inactivation effect. The formula for calculating ultraviolet intensity is: in: I UV : UV intensity; P UV : The power of the UV lamp; A tube : The surface area of ​​the lamp tube.

[0058] Ion generators are used to release negative oxygen ions. Negative oxygen ions can combine with particulate matter and harmful gases in the air, causing them to settle to the ground, thereby improving air quality.

[0059] In a possible implementation, the above components are integrated into an independent module unit. The units are connected by plugging, and the number of modules can be flexibly increased or decreased according to the area of ​​the bathroom. For example, for a bathroom with a large area, multiple purification units can be connected in parallel to enhance the purification capacity.

[0060] In this embodiment, the dynamic airflow guide device is used to optimize the air flow path and improve the air purification efficiency. The guide device is composed of a plurality of adjustable guide plates, which dynamically adjust the angle according to the air flow in the bathroom to make the air pass through the modular purification unit more evenly.

[0061] Generally, the adjustment angle of the guide plate is calculated by the intelligent control module, and the adjustment logic is based on the air flow rate and particle concentration distribution. The air flow rate is calculated as: in: v air : air velocity; Q air : air volume of the fan; A duct : Cross-sectional area of ​​guide plate channel.

[0062] As an option, the dynamic air flow guide device can achieve precise control of air flow by adjusting the angle of the guide plate driven by a servo motor.

[0063] The ventilation device is used to maintain the dynamic balance of indoor and outdoor air and reduce the accumulation of harmful substances. The ventilation device includes an air intake duct and an exhaust duct.

[0064] The air intake duct is equipped with air intake louvers to prevent external foreign matter (such as dust or insects) from entering the system. The air intake volume can be controlled by adjusting the opening and closing angle of the louvers.

[0065] High-efficiency fans are installed in the exhaust duct to exhaust the dirty air in the room. The operation of the fan is dynamically regulated by the intelligent control module, which automatically adjusts the speed according to air quality parameters and traffic density. For example, when the PM2.5 concentration is high, the fan will run at a higher speed; when the air quality is good, it will run at a lower speed to save energy.

[0066] In some embodiments, the ventilation device may further include a secondary filtering device for performing a final purification treatment on the exhaust air to avoid contamination of the external environment.

[0067] The air purification module relies on the air quality data provided by the dynamic monitoring module. The output data of the PM2.5 sensor, VOC sensor, and temperature and humidity sensor in the dynamic monitoring module directly affects the operation intensity and frequency of the purification module. For example, when the VOC concentration increases, the operation time of the activated carbon filter will be automatically extended; when the PM2.5 concentration exceeds the set threshold, the purification module will start more units to work in parallel.

[0068] In addition, the air purification module works in conjunction with the spray disinfection module. For example, when the spray disinfection module performs large-scale atomization spraying, the dynamic airflow guide device of the air purification module automatically adjusts the guide plate angle to ensure that the atomized droplets can be evenly distributed throughout the space.

[0069] The intelligent control module is the core unit of the system of the present invention, which is used to receive real-time data from the dynamic monitoring module, comprehensively analyze crowd density and air quality parameters, and dynamically adjust the operating status of the spray disinfection module and the air purification module. This module optimizes the system operation efficiency and resource utilization through multi-mode operation logic, real-time data processing and feedback mechanism. The real-time data provided by the dynamic monitoring module is directly used as the input of the intelligent control module, and the spray disinfection module and the air purification module complete precise operation according to the control instructions output by this module. The resource management module cooperates with the intelligent control module to further optimize the overall performance of the system by monitoring and recording energy consumption and resource usage.

[0070] In this embodiment, the intelligent control module mainly includes an embedded central controller, a data processing unit and a control unit.

[0071] Generally, the embedded central controller is responsible for coordinating the operation of the entire system. Its core function is to receive data collected by the dynamic monitoring module, including PM2.5 concentration, VOC concentration, temperature and humidity, carbon dioxide concentration, and crowd density, and to normalize and comprehensively analyze these data.

[0072] As an option, the central controller is embedded with an algorithm module to analyze data trends and abnormal changes.

[0073] In this embodiment, the data processing unit is an important component of the intelligent control module, which is used to calculate the spraying dosage of the spray disinfection module and the operating frequency of the air purification module. The data processing unit performs multi-parameter weighted calculation based on the parameters input by the dynamic monitoring module and the preset operating mode.

[0074] As an option, the spray dose is calculated as: V spray (t) = k 1 ·ρ(t)+k 2 ·[1-C norm (t)] in: V spray (t): spraying dose at time t, in milliliters per minute; ρ(t): crowd density; C norm (t): normalized air quality parameter; k 1 , k 2 : Adjustment coefficient, used to balance the weights of crowd density and air quality parameters.

[0075] For the frequency adjustment of the air purification module, the data processing unit calculates the fan speed according to the PM2.5 concentration and VOC concentration in the air. The calculation formula for the fan speed is: v fan (t) = k 3 ·C PM2.5 (t)+k 4 ·C VOC (t) in: v fan (t): fan speed, in revolutions per minute; C PM2.5 (t): PM2.5 concentration at time t; C VOC (t): VOC concentration at time t; k 3 , k 4 : Regulation factor related to fan power.

[0076] Generally, the data processing unit refreshes data once a second to ensure the real-time nature of control instructions.

[0077] Specifically, the main function of the control unit is to convert the calculation results of the data processing unit into specific control signals and send them to each functional module. The control unit includes the following parts: The control signal of the spray disinfection module is generated by the control unit according to the spraying dosage and spraying area. As an option, the opening frequency of the top nozzle and the wall nozzle can be optimized according to the heat map of the flow distribution. For example, when the flow of people is concentrated in the middle of the toilet, the control unit will give priority to opening the middle nozzle and increase the spraying amount.

[0078] The control signals of the air purification module mainly include fan speed adjustment and purification unit start and stop control. Specifically, when the VOC concentration is high, the control unit instructs the activated carbon filter to enter a high-load working state; when the PM2.5 concentration exceeds the set threshold, the fan speed automatically increases to the maximum value.

[0079] In a possible implementation, the control unit can also intelligently control the ventilation device. According to the carbon dioxide concentration and the temperature difference between indoor and outdoor, the control unit dynamically adjusts the intake and exhaust volumes to maintain the dynamic level of indoor air.

[0080] In this embodiment, the intelligent control module supports three operation modes: peak mode, energy-saving mode and automatic mode.

[0081] In peak mode, the system prioritizes efficient disinfection and purification. For example, the spraying frequency of the spray disinfection module is increased to 10 times per minute, and the fan speed of the air purification module is increased to 80% of the maximum power.

[0082] In energy-saving mode, the system adjusts its operating status according to real-time data. For example, when the density of people is low and the air quality is good, the spraying and disinfection module only maintains basic spraying, and some units of the air purification module enter standby mode.

[0083] In automatic mode, the system adaptively adjusts the operating parameters of each module based on the data provided by the dynamic monitoring module. For example, when the PM2.5 concentration increases but the density of human traffic is low, the system prioritizes adjusting the operating status of the air purification module rather than increasing the spraying volume.

[0084] In some embodiments, the intelligent control module can also support remote control and data analysis functions. For example, through a mobile device, the user can view air quality parameters, energy consumption data, and disinfectant usage in real time, and adjust the system operation mode. As a possible option, the central controller can be connected to a cloud server to upload historical data to the cloud for more advanced data analysis and optimization.

[0085] In addition, this module can also be linked with external devices. For example, in some application scenarios, the intelligent control module can receive data from central air conditioning or environmental monitoring equipment, and combine these data to further optimize the operating status of the system.

[0086] The intelligent control module is the core of the coordinated operation of the system's functional modules. The real-time data of the dynamic monitoring module is the basis for the intelligent control module's calculation and decision-making, while the specific operating status of the spray disinfection module and the air purification module is directly driven by the control signal output by the intelligent control module. The resource management module assists the system in long-term optimization by recording the operating data of the intelligent control module.

[0087] The resource management module is used for comprehensive management of disinfectant usage, energy consumption monitoring, and system data recording. This module plays an auxiliary and optimization role in the overall operation of the system. Through closed-loop design and energy consumption optimization logic, it ensures efficient resource utilization and environmental friendliness. The operation decisions and feedback data of the intelligent control module directly provide a basis for the resource management module, while the actual operating status of the spray disinfection module and the air purification module will affect the monitoring and adjustment of the resource management module. This module can not only provide real-time feedback on the current resource usage, but also has data storage and analysis functions, providing an optimization basis for the long-term operation of the system.

[0088] In this embodiment, the resource management module mainly includes a closed-loop liquid recovery device, an energy consumption monitoring unit and a data storage unit.

[0089] Generally, the closed-loop liquid recovery device recovers the incompletely atomized disinfectant through a pipeline and transports it back to the electrochemical disinfectant generation device to achieve resource recycling. The unatomized liquid mainly flows into the recovery pipeline along the surface by gravity, and is then sent back to the disinfectant generation device by a reflux pump.

[0090] Specifically, the recovery device includes a liquid collection tank, a return pipe and a return pump. The liquid collection tank is arranged at the bottom area of ​​the spray disinfection module to collect unused disinfectant on the ground. The return pipe is connected to the liquid collection tank and monitors the flow of the return liquid through a built-in flow sensor. The output result of the flow sensor is calculated by the following formula: Q recycle (t) = v flow ·A pipe in: Q recycle (t): recovered liquid flow rate at time t; v flow : Liquid flow rate in the pipeline; A pipe : Pipe cross-sectional area.

[0091] As an option, the operation of the reflux pump is regulated by the intelligent control module. When the amount of recovered liquid exceeds a set threshold, the reflux pump is started to transport the liquid back to the generation device to supplement the liquid demand of the electrolyzer.

[0092] In this embodiment, the energy consumption monitoring unit is used to monitor the power consumption of the spray disinfection module, the air purification module and other electrical components (such as fans, pumps, UV lamps) in real time. The core of energy consumption monitoring is a plurality of power sensors, which are installed at the power input end of each module to collect power data in real time.

[0093] In general, the power consumption of the system is calculated as follows: in: P total (t): total system power at time t; P i (t): power of the i-th module at time t; N: The number of power monitoring modules in the system.

[0094] In a possible implementation, the energy consumption monitoring unit classifies and counts the power consumption of each module, for example: fan power consumption: monitoring the operating power of the dynamic airflow guide device and the ventilation device in the air purification module.

[0095] UV lamp power consumption: monitors the working status of the ultraviolet germicidal lamp in the air purification module.

[0096] Pump and nozzle power consumption: monitors the power consumption of the return pump and atomizing nozzle in the spray disinfection module.

[0097] As an option, when the total power exceeds the preset safety limit, the energy consumption monitoring unit will send an alarm message to the intelligent control module, which will dynamically adjust the operating status of each module, for example, reducing the spraying frequency or temporarily shutting down some purification units.

[0098] In this embodiment, the data storage unit is used to record the operating parameters of the system, resource usage and air quality changes. These data are uploaded to the data storage unit regularly through the intelligent control module and stored in the form of logs.

[0099] Specifically, the data storage unit includes an internal memory and a data classification logic. The data classification logic divides the system operation parameters into the following categories: Disinfectant usage: Statistics on the disinfectant consumption and recovery in the spray disinfection module.

[0100] Energy consumption data: record the operating power and time of each module, and calculate the cumulative energy consumption.

[0101] Air quality changes: Save the air quality parameters (such as PM2.5 concentration, VOC concentration, etc.) provided by the dynamic monitoring module to evaluate the purification effect.

[0102] As an option, the data storage unit can be connected to a remote server to upload historical operating data to the cloud for subsequent analysis. For example, through trend analysis of operating data, the system can adjust the spraying volume, purification frequency or energy consumption strategy to optimize long-term operating results.

[0103] In some embodiments, the resource management module may also include a consumable replacement reminder function. For example, when the disinfectant concentration in the recovered liquid drops below a set value, the system will trigger an alarm to remind the user to replace the saline solution or clean the electrolytic cell.

[0104] As an option, the resource management module can also support the calculation and display of energy consumption costs. By combining local electricity prices and energy consumption data, the system can estimate the resource consumption cost of each operation and provide users with an economic reference.

[0105] In addition, this module can work together with the spray disinfection module and the air purification module. For example, when it is detected that the disinfectant is about to run out, the resource management module will give priority to reducing the spraying frequency and increase the working intensity of the air purification module to ensure that the air quality is maintained within a safe range.

[0106] The resource management module relies on the real-time data provided by the intelligent control module and is closely related to the operating status of the spray disinfection module and the air purification module. The intelligent control module dynamically adjusts the operating strategy based on the energy consumption and disinfectant usage feedback from the resource management module. For example, when the energy consumption data is close to the set limit, the intelligent control module can reduce the fan speed or reduce the spraying amount to save resources.

[0107] The monitoring results of the resource management module can also provide a basis for long-term optimization of the system. For example, by analyzing the ratio of disinfectant recovery to consumption, the operating efficiency of the spray disinfection module can be evaluated and the nozzle layout or return pipe design can be adjusted accordingly.

[0108] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
