Description

Technical Field

[0001] This invention relates to an ozone-based disinfection system, and more particularly to a modular electrolytic ozone air disinfection and purification system. It belongs to the category of modular systems for air disinfection, which can be configured with interchangeable components to generate, circulate, and neutralize ozone, thereby treating air in enclosed or semi-enclosed environments.

[0002] The present invention includes a purification configuration comprising an air circulation subsystem and an ozone treatment component, and is functionally connected to a water tank configuration to provide a water source, and optionally connected to a dehumidifier configuration or a water source configuration.

[0003] This modular architecture generates ozone from water through an electrolytic ozone generator and reduces residual ozone using catalytic surfaces such as titanium dioxide, enabling flexible deployment across a variety of application scenarios.

[0004] The present invention further relates to a method for safely disinfecting air by creating an oxidizing environment and reducing ozone to a level safe for humans before emission.

[0005] Its applications cover commercial, residential, healthcare, transportation, and industrial scenarios that require scalable and intelligent air handling solutions. Background Technology

[0006] Prior to this invention, disinfection systems designed for air handling, cold storage spaces, and water-soluble ozone delivery generally suffered from various functional and practical deficiencies, which limited their effectiveness, adaptability, and ease of use.

[0007] In the field of general air disinfection, traditional systems are typically closed, non-modular structures with fixed configurations. These systems lack the flexibility to adapt to different installation environments or operational needs. Many existing designs cannot be easily adapted to different physical spaces or integrated with additional disinfection functions such as water treatment or humidity control. Therefore, users often need to install multiple dedicated devices to achieve comprehensive disinfection coverage, increasing system complexity, maintenance burden, and cost. Furthermore, many air handling systems give little consideration to personnel safety during operation—either generating ozone without a reliable mechanism to reduce residual concentrations or failing to effectively regulate airflow within the treated area. These problems are particularly pronounced in environments requiring safe re-entry times and real-time ozone concentration reduction.

[0008] In refrigerated spaces, such as walk-in cold storage, commercial refrigeration equipment, and consumer appliances, disinfection systems face additional challenges. Some early systems attempted to use ozone as a disinfectant in refrigerated compartments, but this was often done uncontrollably or continuously, leading to ozone buildup at levels unsafe for humans or food preservation. There was often a lack of mechanisms to switch between high-ozone disinfection and low-ozone purification modes. This lack of dynamic control raises safety and regulatory concerns, especially in environments governed by Occupational Safety and Health Administration (OSHA) or food safety standards. Furthermore, early systems typically lacked features such as door locking mechanisms, ozone degradation pathways, or integration with ozone sensors, making them unsafe for use in refrigerated environments with intermittent access. These systems also generally neglected the disinfection needs of related water systems (such as those used in ice makers and water dispensers), resulting in incomplete disinfection.

[0009] Regarding the water supply for ozone generation, existing systems heavily rely on permanent piping connections, pressure-driven makeup water systems, or open storage containers, all of which are susceptible to contamination. These solutions present significant limitations in portable or mobile applications, or in installation environments where access to piped water is unavailable. Manual makeup water replenishment is typically cumbersome and can introduce risks of user error or microbial contamination. Even with sealed disposable water filters (if used), intelligent tracking or system interlocking mechanisms are often lacking to prevent ozone generation from activating in the absence of a viable water source. Many systems cannot detect empty, misaligned, or improperly installed filters, potentially affecting safety and disinfection effectiveness. These limitations significantly reduce the practicality of early ozone systems for non-industrial users, mobile service environments, or low-maintenance applications.

[0010] Existing systems typically fail to integrate technologies with intelligent control capabilities, such as the ability to monitor operating parameters, transmit data, or respond based on real-time feedback. Support for remote monitoring, geolocation management, compliance logging, or centralized system management is extremely limited, yet these capabilities are now fundamental requirements for modern networked disinfection platforms. This lack of functionality forces maintenance scheduling, regulatory reporting, and system diagnostics to rely primarily on manual checks or experience-based judgment, reducing system reliability and increasing the burden on technicians and users.

[0011] The cumulative effect of these shortcomings—including rigid structures, inadequate safety controls, poor adaptability, and a lack of convenient maintenance design—has led to the underutilization or even complete abandonment of existing disinfection systems in many environments where they could have provided health and hygiene benefits. These deficiencies in high-risk or dynamic usage environments further highlight the long-standing and unmet need for a multifunctional, intelligent, and modular ozone air and water disinfection solution.

[0012] Based on these reasons and shortcomings, as well as other reasons and defects that the prior art has failed to address, there has long been an urgent need, which led to the creation of this invention. Summary of the Invention

[0013] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a modular electrolytic ozone air disinfection and purification system, which overcomes the deficiencies of the prior art and brings additional advantages. This system employs a flexible architecture design for generating, guiding, and neutralizing ozone, thereby achieving safe and efficient air treatment. The system can be deployed and applied in various environments through purification configurations and interchangeable modules (including water tank configurations, dehumidifier configurations, and water source configurations).

[0014] This invention includes a purification configuration with an air circulation subsystem and a gaseous ozone treatment module. The purification configuration receives airflow and treats the airflow using ozone generated by an electrolytic ozone generator fluidly connected to a water tank configuration. The system includes a fixed water tank or housing for a replaceable water filter cartridge and a titanium dioxide-coated surface in the airflow path to reduce residual ozone concentration. After ozone treatment, the system can reduce the ozone concentration to a level that meets human exposure safety limits before being released into human environments.

[0015] This invention also includes a dehumidifier connected to the water tank. The dehumidifier extracts moisture from the ambient air and delivers it to the water tank, enabling the system to generate ozone autonomously in an environment without piped water supply. The system employs the same purification architecture and has the ability to dynamically switch between different water sources and disinfection modes.

[0016] This invention includes a water source configuration connected to an external water supply pipeline. This configuration directs water through a fluid inlet system to a collection and storage device or directly to a water tank, thereby achieving continuous operation. The generated ozone is used to treat the air within the purification configuration, and the treated air is then released after catalytic oxidation.

[0017] This invention features flexible installation, independent operation, and integration with intelligent control and safety functions. The modules are interoperable and can be used individually or in combination, depending on site conditions and expected application requirements.

[0018] This invention overcomes the shortcomings of existing technologies and provides additional advantages by providing a method for treating air using a modular ozone disinfection system. The method includes: inserting a replaceable water filter cartridge into a water tank configuration functionally connected to a purification configuration; generating gaseous ozone from the water using an electrolytic ozone generator; and introducing the ozone into the purification configuration, where it mixes with an airflow to form an oxidizing environment. Subsequently, the oxidizing airflow contacts a titanium dioxide coating surface to promote the photocatalytic decomposition of residual ozone, after which the treated air is discharged. This method achieves safe and efficient air disinfection through modular components and can be flexibly deployed in various environments.

[0019] The shortcomings of existing technologies are overcome by providing a method for using a modular ozone disinfection system incorporating a dehumidifier configuration. This method includes: extracting moisture from ambient air using the dehumidifier configuration; delivering the extracted water to a water tank configuration; generating ozone; and treating the air using a purification configuration with a titanium dioxide-coated surface. This solution enables autonomous ozone generation without the need for external ducted water supply, making it particularly suitable for mobile or infrastructure-constrained installation environments.

[0020] Other shortcomings are addressed by providing a method for using a modular ozone disinfection system that includes a water source configuration. The method includes: connecting the water source configuration to an external water supply; introducing water through a tank configuration into an electrolytic ozone generator; and mixing the generated ozone with an airflow for disinfection. A titanium dioxide coating surface within the purification configuration reduces the ozone concentration to a safe level for humans before the airflow is emitted. This method supports automated and continuous operation in locations with a stable water supply, such as food service establishments or systems integrated with HVAC systems.

[0021] These methods address the limitations of fixed-function disinfection equipment by introducing modular, intelligent, and safety-controlled disinfection processes. Each configuration is scalable and adaptable, allowing adjustments to be made to meet specific site requirements, thereby improving operational flexibility, user safety, and environmental compliance.

[0023] The specific embodiments of the present invention are described in conjunction with the accompanying drawings, and their advantages and features are illustrated by way of example. Detailed Implementation

[0024] The following detailed description is provided to aid in understanding the invention by illustrating several non-limiting examples and embodiments. While specific structural configurations and functional arrangements have been described for clarity, the invention is not limited to the specific forms disclosed, but can be implemented in various alternative or equivalent ways depending on the application scenario and system requirements.

[0025] This invention proposes an integrated ozone disinfection and purification system applicable to a variety of environments. These environments include, but are not limited to: modular installations (e.g., portable or stand-alone systems), enclosed refrigerated spaces (e.g., ice makers and refrigerator casings), and compact applications employing sealed, replaceable filters to enhance convenience and safety.

[0026] Traditional air purification and disinfection systems typically rely on single-mode chemical treatment, passive filtration, or limited ultraviolet irradiation technology. These systems often underperform in environments requiring dynamic switching between disinfection and safe return air, especially in confined spaces or occupied environments, where residual chemicals such as ozone must be safely neutralized before people re-enter.

[0027] In this invention, the term "modular ozone disinfection system" refers to a system that includes at least a purification configuration and may further include one or more of a water tank configuration, a dehumidifier configuration, and / or a water source configuration, wherein the components are structurally or functionally interchangeable or operablely connected to generate ozone from water for air and / or surface disinfection and may selectively neutralize residual ozone via catalysis.

[0028] In this invention, the term "purification configuration" refers to a configuration that includes an air circulation subsystem and one or more ozone treatment components, including at least a titanium dioxide coated surface for receiving airflow, exposing the airflow to an oxidizing environment containing ozone, and reducing residual ozone to a level that meets applicable human exposure safety limits.

[0029] In this invention, the term "water tank configuration" refers to a water storage system for supplying water to an ozone generation subsystem, which may include a fixed water tank or a housing for receiving replaceable water filter cartridges.

[0030] In this invention, the term "dehumidifier configuration" refers to a subsystem connected to a water tank configuration function, which is used to extract moisture from ambient air through components such as condenser coils, fans, and water collection containers.

[0031] In this invention, the term "water source configuration" refers to a water inlet subsystem for connecting to an external pressurized or non-pressurized water supply pipeline and supplying water to the system through a fluid inlet, and optionally including pressure regulation or backflow prevention functions.

[0032] In this invention, the term "replaceable water filter" refers to a sealed, removable water container for supplying water to an ozone generation subsystem, and optionally includes alignment structures, usage status tracking, and interlocking mechanisms to prevent system malfunction when the filter is depleted or improperly installed.

[0033] In this invention, the term "replaceable water filter status" refers to an indication or status determined based on usage tracking, alignment verification, or remaining water volume, used to determine whether the filter is suitable for continued use, replacement, or to trigger system shutdown.

[0034] In this invention, the term "electrolytic ozone generator" refers to an electrochemical component that generates ozone gas and / or water-soluble ozone from water through an electrolytic reaction, and optionally incorporates ion exchange materials to improve ozone generation efficiency or purity.

[0035] In this invention, the term "ozone concentrate" refers to an aqueous solution composed of water generated by the system and dissolved ozone, which can be used for disinfection of ice makers, water dispensers, or water supply system pipelines.

[0036] In this invention, the term "titanium dioxide coated surface" refers to a surface or substrate coated with titanium dioxide (TiO2) or its photocatalytic variants to promote the decomposition of ozone or other oxides under light or airflow, thereby reducing the ozone concentration in the air through photocatalytic oxidation.

[0037] In this invention, the term "manganese dioxide treatment module" refers to a component containing manganese dioxide (MnO2) configured to react with ozone to generate hydroxyl radicals (•OH), thereby enhancing the oxidation and disinfection effect in the airflow path.

[0038] In this invention, the term "controller" refers to an electronic control system that includes a microcontroller, a memory, and a communication interface, used to adjust system operation based on sensor feedback, stored programs, remote commands, or preset disinfection modes.

[0039] In this invention, the term "manned environment" refers to any space where people may actually be present during or after the processing cycle, including but not limited to residential rooms, commercial kitchens, cold storage rooms, walk-in cold storage, offices, or vehicle interiors.

[0040] In this invention, the term "disinfection mode" refers to a system operating mode in which the ozone concentration is increased to actively disinfect air, surfaces, or waterways; while "purification mode" refers to an operating state in which residual ozone is neutralized or reduced to ensure the safety of air before it is released into the environment, thereby allowing personnel to safely re-enter the treated environment.

[0041] In this invention, the phrase "ozone concentration reduced to a level that meets applicable human exposure safety limits" is used in a non-limiting manner to refer to any ozone concentration in the air at or below applicable human exposure safety thresholds, which are specified by relevant regulatory, occupational health, or environmental health standards. For example, these thresholds may include the Permissible Exposure Limit (PEL) set by the U.S. Occupational Safety and Health Administration (OSHA), which is an average of 0.1 ppm over an 8-hour workday, or the Threshold Limit (TLV) set by the American Conference of American Industrial Hygiene Scientists (ACGIH), which ranges from 0.05 to 0.1 ppm depending on the application. The system can monitor and reduce ozone concentrations to levels significantly below these values ​​before the treated air is released into occupied environments, thereby ensuring safety in a variety of application environments such as medical, food service, and public places.

[0042] In some embodiments, ozone concentration can be measured by an internal ozone sensor and work in conjunction with a titanium dioxide-coated surface or other ozone neutralization components. In other embodiments, the system may rely on a fixed residence time, airflow handling rate, or a calibrated decay profile to passively or actively reduce ozone levels before emission. This statement is intended to cover all such implementations in which residual ozone in the emission gas has been reduced to a level that meets applicable human exposure safety standards.

[0043] Furthermore, traditional systems often lack flexible modular design, resulting in bulky structures, difficult maintenance, or incompatibility with alternative water sources, such as atmospheric condensate or piped water supply. These limitations can affect their deployment in multiple industries, including food service, healthcare, and residential or commercial heating, ventilation, and air conditioning (HVAC).

[0044] To address these challenges, this invention proposes a multifunctional, multi-configuration disinfection system that combines the strong oxidizing power of ozone with advanced catalytic reduction materials. The system includes at least one purification configuration (for air treatment) and can be used in combination with one or more of the following modules: - Water tank configuration for storing water used in ozone generation; - A dehumidifier configuration for extracting moisture from ambient air; and - A water source configuration for receiving water from external pipelines.

[0045] This modular framework supports scalable designs for diverse environments. Configurations can be integrated, stacked, or functionally connected based on space constraints, usage frequency, and water availability. Ozone can be delivered in gaseous form for air handling or in aqueous form for surface and waterway disinfection.

[0046] Interaction between ozone and catalytic surfaces: A core scientific principle of this invention is the interaction between ozone (O3) and catalytic materials. It can be used to convert ozone into safer or more reactive substances.

[0047] Titanium dioxide (TiO2): When an ozone-containing gas stream is directed through the surface of a titanium dioxide coating—especially under ultraviolet light irradiation or high gas flow excitation energy—a photocatalytic oxidation reaction occurs. This reaction decomposes residual ozone into oxygen (O2) while simultaneously oxidizing organic and microbial contaminants in the air. This mechanism enables the system to maintain high disinfection efficiency during ozone generation and subsequently neutralize ozone rapidly, thus supporting safe re-entry or continuous operation in occupied environments.

[0048] Manganese dioxide (MnO2): In some configurations, gaseous ozone can be directed to the manganese dioxide treatment module. MnO2 catalyzes a reaction that converts ozone into hydroxyl radicals (•OH), which possess broad-spectrum antimicrobial activity. This conversion enhances disinfection capabilities while reducing excess ozone. The hydroxyl radicals rapidly react with airborne organic compounds, biofilms, and pathogens, making this method highly effective in enclosed or difficult-to-clean spaces.

[0049] Modular system configuration: In the first embodiment, the system is implemented using modular components that can be combined and matched according to installation requirements. It includes at least a purification configuration for receiving airflow, utilizing gaseous ozone to create an oxidation treatment environment, and neutralizing residual ozone through a titanium dioxide coating surface. Depending on the chosen form, the water tank configuration may include a fixed water storage device or a replaceable water filter, both of which can supply water to the electrolytic ozone generator.

[0050] When atmospheric water resources are available, the dehumidifier and water tank configurations can be linked to autonomously extract and deliver water. In environments with pressurized water supply, an additional water source configuration can be added, enabling the system to operate in continuous ozone generation and purification mode. Any or all of the above modules can be combined according to the target application and can be installed using vertical stacking or adjacent arrangement.

[0051] Refrigeration space configuration: In a second embodiment, the system is suitable for refrigerated environments, such as ice makers or food storage compartments. A key advantage of this invention is its ability to disinfect enclosed spaces using ozone and neutralize residual ozone within the system before releasing air back into the refrigerated space.

[0052] In this configuration, the controller coordinates between the two operating modes: Disinfection mode: Ozone is introduced into the refrigerated space to increase the ambient ozone concentration within a limited time; and Purification mode: Air circulates within the system, passes through a titanium dioxide surface treatment, and returns to the refrigerated space only after the ozone concentration has decreased to a level that meets human exposure guidelines.

[0053] In addition, water-soluble ozone can be used for internal disinfection of ice-making water pipes or water dispenser supply systems. Optional components include a manganese dioxide treatment module for generating hydroxyl radicals, and an electronically controlled locking mechanism to restrict user access during disinfection cycles.

[0054] Filter replacement configuration: In the third embodiment, the system uses a sealed, replaceable water filter cartridge as the sole or primary water source. This version is particularly suitable for consumer, healthcare, and field applications where system portability is critical and manual water replenishment is not possible or piped water supply is unavailable. The purification configuration operates as described in the previous embodiments, treating the ozone stream with titanium dioxide and safely releasing the air once the ozone level has decreased.

[0055] The status of the filter cartridge can be monitored via a microcontroller and sensor system, transmitting alarm information to a remote processing platform or displaying it on a local interface. This design ensures predictable system operation and supports regulatory compliance requirements in critical environments.

[0056] Figure 1 As an application example of the modular ozone disinfection system 100, the system is configured for flexible deployment in a variety of disinfection and purification environments. In one example implementation, the system 100 is installed in a variety of application scenarios, including refrigeration equipment 210, HVAC air handling units 214, commercial kitchens 216, public restrooms / gyms / hospitals / offices and other environments and applications 212, as well as other environments and applications 218.

[0057] This diagram illustrates the adaptability of the modular ozone disinfection system 100 in various operating environments, while maintaining a consistent treatment mechanism centered on ozone disinfection and catalytic purification. The system can be integrated with different air and water sources, control architectures, and communication platforms, enabling it to scale from a standalone device to a distributed enterprise-level deployment.

[0058] The modular ozone disinfection system 100 can be located adjacent to or inside the target treatment environment. For example, in the case of refrigeration equipment 210 (such as a walk-in cold storage or ice maker), the modular ozone disinfection system 100 can be installed in the upper corner of the housing or circulate air into the internal space via external ductwork. Similarly, the modular ozone disinfection system 100 can also be connected to or embedded in a centralized heating, ventilation, and air conditioning (HVAC) air handling unit 214 via ductwork, thereby maintaining the ozone concentration at or below regulatory thresholds while achieving circulating airflow oxidation treatment.

[0059] In commercial kitchen applications 216, public restroom installations 212, and other similar applications, the modular ozone disinfection system 100 can provide continuous or programmable disinfection capabilities and can be selectively integrated with ambient air sensors 512, door triggering mechanisms, or idle-time ozone enhancement cycles. In medical environments (e.g., hospital wards 212) and other similar applications, the modular ozone disinfection system 100 can be configured to operate in conjunction with external monitoring devices, such as remote data processing resources 702 or computing devices 732, for receiving status updates, operating cycle logs, or filter replacement alarms.

[0060] Each modular ozone disinfection system 100 includes at least one purification configuration 170, which houses an air circulation subsystem 104 and an ozone treatment module. Depending on the implementation, it may also include a water tank configuration 172, which may be a fixed water tank or a replaceable water filter cartridge 126. These configurations are fluidly connected to an electrolytic ozone generator 516, which generates gaseous ozone from the water.

[0061] The generated gaseous ozone can be guided through the airflow path of the purification configuration 170 to create an oxidation treatment environment for disinfecting the airflow. Subsequently, the airflow contacts the titanium dioxide coating surface 110, where photocatalytic oxidation promotes the decomposition of residual gaseous ozone, reducing it to a level that meets applicable human exposure safety limits before emission. In some embodiments, the modular ozone disinfection system 100 may also include a manganese dioxide treatment module 112, which reacts with the gaseous ozone to generate hydroxyl (OH) radicals to enhance the chemical disinfection effect. This two-stage treatment method ensures that the modular ozone disinfection system 100 performs efficient active disinfection while ensuring that the output air meets the requirements for safe return to occupied environments.

[0062] Modular design allows the system to be flexibly assembled according to specific installation requirements, application scenarios, location conditions, equipment cost budgets, and other factors. As illustrated in the various applications, the system may further include: Dehumidifier configuration 174: for extracting moisture from ambient air and delivering it to water tank configuration 172; Water source configuration 176: Used to provide a continuous water supply from pressurized or unpressurized external water lines.

[0063] The controller 500 includes a microcontroller 502, a memory 504, and a communication interface 508. The controller 500 can coordinate system operating modes and monitor the environment and internal status using sensors 512, thereby enabling programmable control of various operating modes and processing cycles. The controller can also selectively communicate with external systems such as remote resources 702 / 732 via wireless, wired local area network (LAN), wide area network (WAN), global network 700, and other communication methods. The Internet can be used as a global network 700 for connectivity.

[0064] In certain applications, particularly in healthcare, food service, and other suitable installation environments, the modular ozone disinfection system 100 can record disinfection activities, ozone levels, or filter usage data to a database 800. This database can store notification records 814, geofencing records 806, and technician maintenance logs for maintenance and compliance management.

[0065] See Figure 2 An example is shown where a water-soluble ozone generator 530 is detachably connected to a tubing housing 178 of a modular ozone disinfection system 100. In one example embodiment, the water-soluble ozone generator 530 can be detachably installed inside or near the tubing housing 178 via a modular interface or quick-connect system, thereby enabling filter replacement, system upgrades, or technician maintenance.

[0066] The modular ozone disinfection system 100 integrates the generation capabilities of water-soluble ozone and gaseous ozone in a modular manner within the same basic unit, enabling a single device to perform water treatment, surface disinfection, and air purification functions depending on the installation scenario and operating procedures. As shown in the figure, the modular ozone disinfection system 100 supports flexible maintenance without interfering with the connected fluid loops, thus offering significant advantages in terms of reliability, safety, and total cost of ownership.

[0067] The water-soluble ozone generator 530 may include an electrolytic ozone generator 516, which generates ozone through an electrolytic reaction using ion exchange material 534. This structure enables the system to simultaneously produce ozone concentrate 114 and gaseous ozone. The ozone concentrate 114 can be transported via internal or external water lines for disinfection of water supply systems in refrigerators, ice makers, and other pipelines with high hygiene requirements.

[0068] The housing 178 with piping is designed to remain fixed in the system's fluid loop, allowing water to flow steadily through the system and into the water-soluble ozone generator 530, while providing maintenance access points for the ozone generating components. The housing 178 includes a maintainable interface 180 for replacing consumable components such as the electrolytic ozone generator 516 and ion exchange material 534, which degrade in performance over time or with prolonged use. These consumables are secured with fasteners, which can be threaded fasteners, snap-fit ​​structures, turn-locking rings, or other suitable securing devices.

[0069] This structure enables technicians 302 to perform safe and efficient maintenance on the equipment without affecting or damaging the core piping structure of the system. The fixed housing 178 with piping ensures fluid tightness and pressure integrity while still supporting routine maintenance, field replacement, or component upgrades.

[0070] Sensors (such as sensor 512) can be used to monitor ozone output, fluid pressure, or conductivity, and feed the data back to microcontroller 502. Microcontroller 502 can then adjust operating parameters or send alarm information to computing device 732 or remote data processing resource 702. System location and maintenance logs can also be tracked via GPS module 514, enabling automated technician dispatch or geofencing management of sensitive deployment areas.

[0071] See Figure 3 Figure A illustrates an example of a modular ozone disinfection system 100, which includes a purification configuration 170 and is functionally connected to a water tank configuration 172. In one example implementation, this configuration represents a basic modular structure for treating air using ozone generated from a water source.

[0072] The figure illustrates a basic embodiment of a modular ozone disinfection system 100, which provides efficient and adaptable air purification capabilities in a compact and easy-to-maintain structure, while supporting both fixed and replaceable water sources.

[0073] The purification configuration 170 includes an air circulation subsystem 104, such as one or more fans, for drawing ambient air into the housing, mixing it with gaseous ozone generated within the system, and guiding the airflow across a titanium dioxide-coated surface 110 to reduce residual ozone concentration before emission. This structure creates an oxidizing environment in the airflow path, enabling the system to disinfect airborne pathogens, volatile organic compounds (VOCs), and odors, while ensuring that the emitted air meets safety limits for re-entry into shared or enclosed spaces.

[0074] In one example implementation, air enters the system through inlet 402 and is drawn into the housing by the air circulation subsystem 104 (which may include one or more fans). The incoming air travels along airflow path 404, which is located within the purification configuration 170. As the air flows along path 404, it comes into contact with gaseous ozone generated or injected into the system by the electrolytic ozone generator 516, thereby creating an oxidizing environment for reducing air pollutants. Subsequently, the oxidizing airflow enters the treatment chamber and is guided through a titanium dioxide coated surface 110 located in the airflow path. As the air flows over this surface, a catalytic reaction occurs, decomposing residual ozone and other volatile organic compounds (VOCs), thereby reducing ozone levels to levels suitable for human exposure. Finally, the purified air is discharged through outlet 408, completing the controlled airflow circulation path. The overall structure of this airflow path ensures that the disinfection process is carried out in a closed and sequential manner, and optimizes ozone efficiency and subsequent safety by rationally arranging the treatment areas between the inlet and outlet.

[0075] The water tank configuration 172 supplies water to the electrolytic ozone generator 516, which uses ion exchange material 534 to convert water into gaseous ozone and ozone concentrate 114. In some embodiments, the water tank configuration 172 includes a fixed internal water storage device; in other embodiments, it includes a housing for receiving a replaceable water filter cartridge 126. Using the filter cartridge 126 allows for replacement with a sealed, pre-filled water source without the need for manual water replenishment or piping connections, thereby simplifying maintenance and improving hygiene—especially suitable for environments where professional maintenance personnel may be lacking, such as clinics, office spaces, or residences.

[0076] This basic modular structure can be applied to a variety of exemplary implementations, including but not limited to: - Portable room disinfection device suitable for dormitories, conference rooms or hotel settings; - A portable, upright unit for use in medical waiting areas or public reception halls; - Desktop or under-desk air handling units for shared office environments or call centers; - Countertop equipment for food processing areas, nail salons, or personal care spaces; - Compact embedded modules for equipment manufacturers, such as integrated ozone disinfection solutions for ice makers, beverage machines, or under-sink filtration systems; and - Other environments, scenarios, and applications.

[0077] Compared to existing technologies, this combination of purification and water tank configuration offers significant advantages. Traditional systems typically rely on direct piping connections, permanent water storage devices, or single-function filter media. This invention, however, achieves: Flexible water supply methods can be achieved through fixed water tanks or sealed filter cartridges; Modular maintenance allows each module to be replaced or upgraded independently without disassembling the entire system. Dual-mode ozone output capability, allowing selection of water-soluble ozone or gaseous ozone according to operational needs; It integrates ozone neutralization, breaking down excess ozone through a titanium dioxide-coated surface before the air is returned to the treated environment; and other functions and benefits.

[0078] In particular, the use of replaceable water filter cartridge 126 enables the system to achieve controlled dosage, avoids direct contact between the user and the raw water, and supports a highly portable system design—making it reliably applicable to rental locations, mobile environments, or the consumer market.

[0079] The operation of the modular ozone disinfection system 100 can be monitored and controlled by a controller 500, which includes a microcontroller 502 for coordinating functions such as fan operation cycles, ozone generation sequence, and safety interlocks. Sensors 512 provide real-time feedback data and transmit it to a remote data processing resource 702 or a computing device 732 for maintenance records or compliance management. The system can also be optionally equipped with a GPS module 514 and cloud services to achieve functions such as location tracking, technician dispatching, enterprise-level geofencing, or other applications.

[0080] See Figure 3 Figure B illustrates an example of a modular ozone disinfection system 100, which includes a purification configuration 170, a water tank configuration 172, and a dehumidifier configuration 174. This embodiment... Figure 3 The system has been expanded based on the configuration shown in A by adding an autonomous water source module, enabling continuous or replenishable ozone generation without the need for pipeline water supply or manual water replenishment.

[0081] The figure illustrates an advanced embodiment of the modular ozone disinfection system 100, in which the integration of a dehumidifier configuration 174 enables the system to operate autonomously independent of external water supply, thereby significantly enhancing its deployment capability in environments where water access or maintenance conditions are limited.

[0082] In one example implementation, the purification configuration 170 receives ambient air, mixes the air with gaseous ozone generated by the system, and passes the oxidizing airflow through the titanium dioxide coated surface 110 to catalytically decompose excess ozone. The air circulation subsystem 104 includes one or more fans for drawing air into the system and expelling treated air, reducing its ozone concentration to a level suitable for entry into occupied environments. This air purification process supports continuous operation and programmable disinfection cycles and is controlled by a microcontroller 502, while also incorporating environmental input information from one or more sensors 512 for adjustment.

[0083] The water tank configuration 172 is located below or near the purification configuration 170 and serves as the main water source for the electrolytic ozone generator 516. The ozone generator 516 uses ion exchange material 534 to convert water into gaseous ozone and / or ozone concentrate 114. In this embodiment, the water tank configuration 172 can be a fixed water storage device or configured to receive replaceable water filter cartridges 126 to accommodate different maintenance methods and system portability requirements.

[0084] The addition of dehumidifier configuration 174 enables the system to autonomously extract moisture from ambient air and deliver it to water tank configuration 172. In one embodiment, dehumidifier configuration 174 includes condenser coil 124, a fan assembly of air circulation subsystem 104, and water collection container 108. These components work together to condense and recover moisture from the air and reintroduce the collected water into the water tank for ozone generation. This configuration eliminates the need for manual water replenishment or piped water supply, making the system particularly suitable for remote, mobile, or infrastructure-constrained installation environments.

[0085] Exemplary applications of this embodiment include: - Portable or mobile disinfection devices for emergency shelters, clean rooms or field hospitals; - Applications for air handling systems in public transportation or fleet vehicles, where external piped water supply is not practical; - Smart home appliances capable of autonomously maintaining water levels and disinfection capabilities; - Industrial safety-critical locations that require long-term maintenance-free operation; and - Other application scenarios.

[0086] This modular architecture allows the purification configuration 170, water tank configuration 172, and dehumidifier configuration 174 to be assembled in a stacked or side-by-side structure according to installation space requirements. Fluid connections between modules are achieved via quick connectors or internal channels, while electrical signals are connected to the controller 500 via a unified wiring harness. The controller 500 is configured to regulate ozone generation, activate the dehumidification function based on the water tank level, and coordinate fan speed or operating cycle according to preset operating modes.

[0087] The optional Global Positioning System (GPS) module 514 supports geofencing deployment, technician route scheduling 302, or area compliance tracking. Status reports, alarms, and maintenance data can be transmitted via network communication to computing device 732 or remote data processing resource 702.

[0088] See Figure 3Figure C illustrates an example of a modular ozone disinfection system 100, which includes a purification configuration 170, a water tank configuration 172, and a water source configuration 176. This embodiment demonstrates how the system can be modularly connected to a continuous external water supply (pressurized or unpressurized) without requiring a built-in water storage device or atmospheric water intake device.

[0089] The figure highlights how the modular ozone disinfection system 100 is suitable for continuous operation in fixed installation environments with utility connections, thus providing a scalable disinfection solution that maintains flexible deployment capabilities while reducing consumable usage.

[0090] In one example implementation, the water source configuration 176 includes a fluid inlet 182 and connecting components for connection to an external water supply line. This inlet may include a pressure regulator, a flow control valve, and an anti-backflow mechanism to ensure safe delivery of water to the water tank configuration 172 without introducing contamination or pressure instability. In this embodiment, the water collection container 108 serves as a buffer storage unit for receiving water from the water source configuration 176 and delivering it to the water tank configuration 172, which then supplies water to the electrolytic ozone generator 516. The electrolytic ozone generator 516 utilizes ion exchange material 534 to generate gaseous ozone and / or a water-soluble ozone concentrate 114.

[0091] The generated gaseous ozone is introduced into the purification configuration 170 and mixed with incoming air in an internal airflow path. Air enters the system through inlet 402 and is drawn into the system by a fan assembly in the air circulation subsystem 104. Starting from the inlet, the air travels along airflow path 404, where it combines with ozone to form an oxidation treatment zone. This airflow path may include an ozone injection chamber or channel area for controlling ozone concentration and contact time. Downstream, the oxidizing airflow is guided through a titanium dioxide coated surface 110, where photocatalytic oxidation reduces ozone concentration and neutralizes volatile organic compounds (VOCs), bacteria, and odors.

[0092] The treated airflow is then discharged through outlet 408, completing the disinfection cycle. The air discharged from outlet 408 has been purified and the ozone concentration has been significantly reduced, making it safe to release into occupied or enclosed environments, such as refrigerated spaces, food processing areas, clean rooms, and other locations.

[0093] This embodiment is particularly suitable for environments with dedicated water supply pipelines, such as: - Commercial kitchens or food service areas, where disinfection and continuous operation are crucial; - Medical cryogenic storage equipment, such as pharmaceutical or vaccine refrigeration units, in which microbial control must be maintained with minimal human intervention; - Installation environments for integrated HVAC systems, where reliable water supply lines are available and frequent maintenance is difficult; and - Other application scenarios.

[0094] The use of water source configuration 176 eliminates reliance on water filters or dehumidifiers, enabling long-term autonomous operation while still allowing precise management of ozone generation by controller 500. Controller 500 can dynamically adjust fan speed, ozone dosage, and purification cycle time, and can interact with sensor 512, remote data processing resource 702, and computing device 732 to achieve real-time feedback and remote maintenance. The system can also be optionally equipped with GPS module 514 for geofencing, asset tracking, and regional compliance reporting.

[0095] See Figure 3 Figure D illustrates a fully integrated embodiment of a modular ozone disinfection system 100, comprising a purification configuration 170, a water tank configuration 172, a dehumidifier configuration 174, and a water source configuration 176. This embodiment demonstrates the system's complete modular architecture, maximizing flexibility, autonomy, and reliability in diverse operating environments by combining multiple water supply methods.

[0096] This diagram illustrates how the modular ozone disinfection system 100 meets diverse needs while maintaining consistent purification functionality through interchangeable or collaborative water supply modules. Each configuration module can operate independently but is integrated through an intelligent control system, providing reliability and adaptability across a wide range of deployment scenarios.

[0097] In this embodiment, ambient air is drawn into the purification configuration 170 via inlet 402 by an air circulation subsystem 104 (which may include a fan or blower). The incoming air is guided along an internal airflow path 404, where it mixes with gaseous ozone generated within the system to create an oxidizing environment for disinfection. Subsequently, the oxidizing airflow is guided through a titanium dioxide coating surface 110 located in the airflow path, which reduces residual ozone and decomposes volatile organic compounds (VOCs) and airborne pollutants through photocatalytic oxidation. The treated air is then discharged through outlet 408, reducing the ozone concentration to a level suitable for entry into occupied environments or other enclosed environments.

[0098] An electrolytic ozone generator 516 and an ion exchange material 534 (or in fluid communication therewith) receive water from a water tank configuration 172 and generate gaseous ozone and ozone concentrate 114 through an electrochemical reaction. The water tank configuration 172 may include a fixed water storage tank 184 or a water source housing 156 for receiving a replaceable water filter cartridge 126.

[0099] Water can be delivered to water tank configuration 172 from two potential sources: - Replaceable water filter cartridge 126; - Dehumidifier configuration 174: It includes a condenser coil 124, a fan assembly in an air circulation subsystem 104, and a water collection container 108 for extracting moisture from ambient air and collecting it for system use; - Water source configuration 176: This includes a fluid inlet 182 that allows water from an external continuous water supply (e.g., a piped municipal water supply) to be introduced into the system. Water source configuration 176 can be fluidly connected to a collection container 108 or directly to a water tank configuration 172. This dual-path water delivery capability allows the system to dynamically select the water source based on environmental conditions, availability, or system preferences.

[0100] During operation, the water collection container 108 serves as an intermediate buffer unit, collecting water from the dehumidifier and selectively receiving supplemental water from the water source configuration 176. The water collection container 108 then delivers the water to the water tank configuration 172, which in turn supplies water to the electrolytic ozone generator 516. Alternatively, when needed, the water source configuration 176 can also directly supply water to the replaceable water filter 126 or the fixed water storage tank 184, thus bypassing the dehumidification system when necessary.

[0101] The controller 500 coordinates the operation of various configuration modules, including ozone generation timing, fan speed, water source priority, and safety interlocks. It can execute preset disinfection programs and respond to sensor inputs (such as ambient air sensor 512, ozone sensor 522, humidity sensor 518, liquid level sensor 552, temperature sensor 556, or other system sensors), while also transmitting data to remote data processing resource 702 or computing device 732. An integrated GPS module 514 enables location-based monitoring, technician tracking, and compliance management.

[0102] This embodiment offers the highest level of autonomy and operational flexibility, making it particularly suitable for long-term deployments with limited maintenance, or environments where water quality conditions may change. Example applications include: - Integration with key HVAC and hospital ward systems that combine automatic water replenishment and air purification functions; - Scenarios requiring multiple disinfection modes, such as walk-in refrigerated spaces or commercial ice makers; - Portable disinfection service terminals or independent air handling tower equipment enable maintenance-free operation; - Remote field operating environments where humidity and municipal water supply conditions may be unstable; and - Other application scenarios.

[0103] See Figure 4An example of a modular ozone disinfection system 100 is shown, configured to operate inside or near a refrigeration unit 210, such as an ice maker, refrigerator, freezer, or other enclosed refrigeration unit. In one example embodiment, in a refrigeration unit disinfection application, the modular ozone disinfection system 100 provides a comprehensive and programmable solution for maintaining hygiene in a refrigerated environment through intelligent airflow management (i.e., switchable purified air 408, gaseous ozone 414, and optional hydroxyl radical-enhanced air 416), catalytic ozone decomposition, and an optional water loop 418, far exceeding the capabilities of solutions relying solely on filtration or static ozone systems.

[0104] This invention aims to perform three complementary disinfection functions: - Use gaseous ozone for air purification; - Surface sterilization using oxidizing airflow; and - Use water-soluble ozone to disinfect water pipes and ice-making containers.

[0105] The purification configuration 170 includes an internal air circulation subsystem 104, which draws in ambient air from the refrigerated compartment through air inlet 402 and propels the air along airflow path 404. In this path, the air comes into contact with gaseous ozone 414 generated by electrolytic ozone generator 516, creating an oxidative treatment environment capable of neutralizing airborne pathogens, fungi, and odors. Subsequently, the treated air is guided through a titanium dioxide coating surface 110, where a photocatalytic oxidation reaction occurs to safely decompose residual ozone and volatile compounds. Finally, the air is exhausted through outlet 408, returning to the refrigerated compartment as purified airflow 408.

[0106] In one example implementation, the modular ozone disinfection system 100 is configured to generate not only one type of airflow 422, but multiple types of airflow 422, including: - Purified Air 408 (for continuously circulating low-ozone air); - Ozone-enriched air 414 (for short-term disinfection cycles); and - Hydroxyl-enhanced air 416 (generated by passing ozone through manganese dioxide treatment module 112, thereby producing hydroxyl radicals).

[0107] This ability to switch between different airflow types 422 gives the system a key advantage: it can cycle between oxidation disinfection mode and safe purification mode, thus forming a programmable processing cycle that maximizes disinfection effectiveness while maintaining air quality. For example, the system can increase ozone concentration for deep surface disinfection during idle periods when no one is using it, and automatically switch to purified air circulation mode before users enter.

[0108] In addition to air treatment, the system includes a water-soluble ozone circuit 418, which is fluidly connected to an electrolytic ozone generator 516. This generator also utilizes ion exchange material 534 to produce ozone concentrate 114. The water-soluble ozone circuit 418 is configured to deliver this ozone water to one or more water lines 240 used in ice makers or refrigerator water dispensers, thereby disinfecting internal pipes, valves, and water nozzles. This function effectively prevents biofilm, microbial growth, and mold formation, which are common sources of failure in high-frequency drinking water or ice-making systems.

[0109] like Figure 4 As shown, an ice-making tank or water outlet device generates ice blocks 420, which can be exposed to purified air or ozone-rich air depending on the system mode. The controller 500 manages operating state switching, water flushing, ozone generation, and circulation time via sensors 512 and external scheduling logic. Simultaneously, alarms or maintenance logs can be transmitted via remote data processing resource 702 or computing device 732, and equipment positioning or geofencing compliance management can be performed using GPS module 514.

[0110] The advantages compared to traditional methods include: Traditional systems lack the ability to dynamically switch between different airflow processing modes, while this invention can achieve this function through internal catalytic components and intelligent control; - Traditional air purifiers typically release ozone without controlling residual ozone. This invention ensures compliance with air quality standards through titanium dioxide oxidation. - Most commercial ice-making and water-drinking equipment rely solely on filtration, which cannot effectively treat biofilm and internal surface contamination. This system combines gaseous and water-soluble ozone to disinfect both the air and water. - The modular architecture allows the system to be customized to different installation conditions (piped water supply, dehumidified water supply, or filter-based water supply) and enables complete water and air circulation control; and - Other advantages.

[0111] Use Case 1: Ice maker for hotel or fast food service (QSR) When installed in countertop or freestanding hotel, fast-food service (QSR), or other similar ice makers, the modular ozone disinfection system 100 operates in a cyclical manner. During idle periods, the system enters disinfection mode, releasing ozone-rich air 414 to disinfect the internal walls and ice storage tank surface. It then switches to a purified airflow 408 during customer-facing periods. Simultaneously, water-soluble ozone 114 is flushed into the water circuit 240 to disinfect the water inlet and ice tray before the next freezing cycle. The controller 500 ensures safe operation and prevents opening during ozone circulation via an automatic door lock mechanism.

[0112] Use Case 2: Mini-fridges, dormitory rooms, recreational vehicles (RVs), marine / maritime equipment or lounge units For small under-sink or household refrigerators 230, the system can be integrated into the rear compartment or side wall. The system continuously purifies the internal air via air purification 408 while periodically flushing ozone-treated water into the water path 240. Replaceable water filter 126 makes this configuration low-maintenance and suitable for consumer applications. Integration with a cloud-based alarm system allows service technicians to remotely monitor filter and water lifespan.

[0113] Use Case 3: Walk-in refrigerator or freezer In a commercial walk-in refrigerated space 210, the system can be wall-mounted and connected to either a water supply configuration 176 or a dehumidification configuration 174. During planned downtime, the system enters disinfection mode, using ozone gas 414 or hydroxyl-rich air 416 to disinfect shelves, walls, and airflow ducts. Before restarting, the system switches to purification mode to restore air quality to safe levels. Relevant operational logs can be stored in a database 800 and used for hygiene inspection compliance traceability.

[0114] In some embodiments, the modular ozone disinfection system 100 may also include a door locking mechanism electrically connected to the controller 500 for locking the access door of the refrigeration unit 210. This safety feature is particularly important when the system is in disinfection mode, as the system increases the ozone concentration inside the chamber using ozone-rich air 414 or hydroxyl-rich air 416. During these cycles, the controller 500 can activate the door lock at the start of treatment to prevent accidental opening of the equipment. The sensor 512 continuously monitors the internal ozone concentration, and the controller 500 automatically unlocks the door once the ozone concentration on the titanium dioxide coated surface 110 has decreased to a preset safety threshold in the purification configuration 170, allowing safe opening of the door.

[0115] This approach not only ensures user safety but also meets regulatory compliance requirements in commercial environments, such as medical facilities, hotels, and food storage facilities where ozone exposure limits are strictly controlled.

[0116] In another example operating scenario, the modular ozone disinfection system 100 supports an interruption-driven safety handling mechanism. If the disinfection cycle is interrupted due to factors such as a door not being properly closed, a door being opened, an emergency signal, power fluctuations, or sensor triggering, the controller 500 can immediately switch the system from disinfection mode to purification mode. In this protective state, ozone generation stops, and the air circulation subsystem 104 continuously circulates internal air through the titanium dioxide coated surface 110, accelerating the reduction of ozone to a safe level. This mechanism ensures that sudden interruptions do not lead to prolonged high ozone exposure or the risk of system downtime.

[0117] See Figure 5The diagram illustrates a block diagram example of a modular ozone disinfection system 100. The system is structurally modularized into multiple key configuration units to support flexible disinfection and purification applications in various environments. These include: a purification configuration 170, a water tank configuration 172, a dehumidifier configuration 174, and a water source configuration 176. These modules can operate collaboratively or independently. Vertical dashed lines represent subsystem group boundaries: water source boundary 352, dehumidifier boundary 354, water tank configuration boundary 356, and purification control boundary 358.

[0118] This diagram illustrates the modularity, maintainability, and intelligence of the Modular Ozone Disinfection System 100, providing a clear contrast to traditional ozone purifiers. Traditional equipment typically lacks programmable modes, multi-source integration, residual ozone control, and intelligent control interfaces. This architecture supports both standalone and enterprise-scale deployments, making it suitable for highly regulated and safety-sensitive environments.

[0119] The system includes a purification configuration 170 that draws in ambient air through an inlet 402, which is then drawn into the system via a fan assembly in an air circulation subsystem 104. The air flows along an airflow path 404 and mixes with gaseous ozone 414 generated by an electrolytic ozone generator 516, creating an oxidizing and disinfecting environment. The oxidizing air then passes through a titanium dioxide-coated surface 110 to reduce residual ozone, which is then decomposed through photocatalytic oxidation. In some embodiments, a manganese dioxide surface 112 is also provided downstream to further convert ozone into hydroxyl radicals, forming hydroxyl-rich air 416. The system can selectively operate in modes that release ozone-rich air 414, hydroxyl-rich air 416, or purified air 408, and then returns the air to the treatment space through an outlet 408.

[0120] Water for ozone generation is provided by a water tank configuration 172, which may include a fixed water storage tank or a housing for a replaceable water filter cartridge 126 disposed within a water source housing 156. A water pump 128A, a check valve 130, and piping 136 form a fluid connection to an electrolytic ozone generator 516, which utilizes ion exchange material 534 to generate gaseous ozone and / or ozone concentrate 114. Liquid volume is monitored by an upper level sensor 152 and a lower level sensor 154.

[0121] To enhance system autonomy, a dehumidifier configuration 174 can be installed. This configuration includes a condenser coil 124, a fan assembly for an air circulation subsystem 104, and a water collection container 108 for condensing and storing ambient water vapor. The dehumidified water can be transported to a water tank or filter cartridge via connected fluid lines and valves. The dehumidifier's water intake process is regulated by a dehumidification control module 524, which receives commands from the system controller and responds based on humidity or temperature thresholds.

[0122] The system may also include a water source configuration 176, which is connected to an external continuous water supply via a fluid inlet system 182. Water from this source can be directly delivered to a collection container 108 or a water tank configuration 172, depending on the installation mode and requirements. The water flow can be pressure regulated and may include a check device to ensure fluid isolation and system safety.

[0123] All these configurations are uniformly coordinated and controlled by controller 500, which includes microcontroller 502, memory 504, display 506, communication interface 508, and general purpose input / output (GPIO) interface 510. The controller manages fan operation (via fan controller 528), pump and valve timing control (pump and valve controller 520), and ozone generation strategy. Simultaneously, the controller also collects data from sensor 512, which may include ozone concentration, water level, humidity, temperature 556, or system diagnostic information.

[0124] A crucial component of the system is the dashboard or control interface (labeled "A"), which may include a touchscreen, control panel, or display module, and can be mounted externally to the system or connected remotely. Through this interface, technicians or users can observe real-time status indicators, including: - Running status; - Low water level; - Warning or error; - Hydroxyl group (OH) formation activation; - Ozone generation activation; - Purification mode is enabled; - Disinfection cycle timing; or - Other statuses, indicators, or functions.

[0125] In addition to providing feedback, the control interface (labeled "A") also supports mode selection, parameter settings, and the execution of preset disinfection programs. This allows facility managers, technicians, or automated control systems to customize system operation for specific environments, such as cold storage spaces, HVAC ducts, or food service areas.

[0126] Remote control and data logging can be achieved via communication interface 508, and cloud access is supported via remote data processing resource 702, computing device 732, or mobile dashboard. The system also includes a GPS module 514 for location tracking, geofencing, and service scheduling.

[0127] See Figure 6An example of a replaceable water filter cartridge 126 for a modular ozone disinfection system 100 is shown. In one example embodiment, the replaceable water filter cartridge 126 includes a sealable water reservoir that can be pre-filled and sealed during the manufacturing or maintenance phase to prevent contamination during transport, storage, installation, or other processes. This sealed design ensures hygienic handling, avoids direct user contact with or replenishment of the water source, and is ideal for sensitive environments or consumer-facing installation scenarios.

[0128] In other embodiments, the replaceable water filter cartridge 126 may also be refillable. For example, a technician 302 or trained personnel may replenish it using a suitable water source. In such configurations, the filter cartridge may include a removable sealing cap 158 or a filling port to allow for clean and safe water replenishment while maintaining system integrity.

[0129] The type of water used in the replaceable water filter cartridge 126 can vary depending on application requirements and operating parameters. In some embodiments, distilled water, deionized water, electrolyte-enhanced solutions, or other water types suitable for the electrolytic ozone generator 516 and internal system components (including ion exchange material 534) can be used. Using pure or specific water sources helps improve ozone generation efficiency, reduce mineral deposits within the system, and extend the life of the electrolytic cell.

[0130] During operation, the structure of the replaceable water filter cartridge 126, its interaction with the water tank configuration 172, and its system-level integration with the controller 500 together constitute a highly maintainable, user-friendly, and reliable disinfection solution suitable for various environments.

[0131] The replaceable water filter cartridge 126 is detachably inserted into the corresponding housing 156 in the water tank configuration 172. The filter cartridge may include alignment features, such as an alignment flange 162 and an outer profile 160, to guide the user for correct insertion and prevent incorrect installation. The filter cartridge may also be provided with a sealing cap 158 to maintain internal sterility before installation and to achieve a sealed connection with the fluid connection port after correct installation.

[0132] During operation, replaceable water filter 126 supplies water to electrolytic ozone generator 516, which uses ion exchange material 534 to generate gaseous ozone or ozone concentrate 114 depending on the selected treatment mode. The generated ozone can be introduced into purification configuration 170 for air disinfection or delivered to downstream water-soluble ozone circuits for water treatment applications.

[0133] In one example implementation, the system monitors the usage of replaceable water filter cartridge 126 via controller 500, which records the number of ozone generation cycles or total operating time. Based on this data, controller 500 determines the cartridge replacement status and disables the ozone generator when the cartridge is depleted or removed, thereby preventing equipment damage or unsafe operation. In some implementations, this status may also be sent to remote computing devices or data processing resources for compliance monitoring, maintenance planning, or alarm generation.

[0134] This cartridge-based solution offers significant advantages over traditional water storage systems that require manual replenishment, as the latter are often prone to contamination risks, water treatment errors, or system downtime. With the use of sealed, disposable cartridges 126, users or maintenance personnel only need to replace the cartridge, requiring no special tools or professional training, thus enabling quick and hygienic maintenance.

[0135] Replaceable water filter cartridge 126 performs particularly well in at least three typical application scenarios: - Small or portable air purification devices in hospitals, dental clinics or other similar settings may pose an infection control risk due to frequent contact with water containers in these settings; - Hotel or guest room ozone equipment, staff can easily replace the filter during routine guest room cleaning; - Mobile air and water disinfection equipment for disaster relief or on-site medical settings, where reliability and rapid replacement capabilities are crucial; and - Other application scenarios.

[0136] See Figure 7 An example controller 500 of a modular ozone disinfection system 100 is shown. This control system provides centralized, programmable, and remotely accessible logic for managing the operation of the air, water, and sensing subsystems, and adapts to different modular configurations. This system is particularly suitable for Internet of Things (IoT) deployment environments, applicable to scenarios with high safety or compliance requirements, such as healthcare, food processing, hospitality, and commercial refrigeration.

[0137] The core of the controller 500 is the microcontroller 502, which is responsible for logic processing and real-time execution of the operation process. The microcontroller 502 is electrically connected to the memory 504, which may include volatile and non-volatile memory types for storing data such as operating modes, sensor thresholds, diagnostic logs, and firmware.

[0138] The microcontroller 502 can be an Intel, Zilog, Microchip, AMD, ARM, or other microcontroller types suitable for specific deployment needs.

[0139] The memory 504 may include a combination of various storage media, such as random access memory (RAM), read-only memory (ROM), flash memory, hard disk, solid-state drive, USB flash drive and other suitable storage media.

[0140] The display 506 is integrated with the general purpose input / output (GPIO) interface 510 for local system interaction. The display 506 can be a digital dashboard or a touch screen panel, and can be used to display operating status indicators, such as operating status, low water level, warnings, O3 generation, and OH generation, and can also be used for mode selection or parameter setting.

[0141] The communication interface 508 is used for wired or wireless connection with external systems, including remote data processing resources 702, computing devices 732, and cloud dashboards. This interface supports real-time telemetry, system alarms, remote coverage control, and operation log recording via Wi-Fi, Ethernet, 4G / 5G, Bluetooth, and other protocols.

[0142] The communication interface 508 may include LAN, WAN, USB, Ethernet, RS232, RS485, serial port, Wi-Fi (802.11abgn or similar standard), 2G, 3G, 4G, 5G, Bluetooth, Zigbee, TCP, UDP, Mesh network, Pico network or other required communication protocols.

[0143] Communication interface 508 is configured to enable control system 500 to communicate with remote data processing resources 702, computing devices 732, and other data terminals via a global network 700, such as the Internet. This connectivity allows the system to transmit and receive operational data, enabling real-time control, remote monitoring, and diagnostics. For example, it can remotely report and monitor operating status, ozone concentration levels, operating time indicators, consumable status (such as the electrolytic ozone generator 516 or ion exchange material 534), or location information provided by GPS module 514. Through this architecture, microcontroller 502 can process input data from sensor 512, perform calculations based on control logic in memory 504, and issue commands to various subsystems (such as pump and valve controller 520, fan controller 528, or dehumidification control module 524). This control infrastructure enables real-time, intelligent automatic control and safe operation, supporting the modular ozone disinfection system 100 in performing purification, water-soluble ozone delivery, and disinfection cycle management under different configurations.

[0144] In one example implementation, General Purpose Input / Output (GPIO) 510 may include transistor-to-transistor (TTL) logic, complementary metal-oxide-semiconductor (CMOS) circuitry, buffers, relays, buttons, switches, and other suitable input / output devices and circuitry. GPIO 510 is functionally associated with microcontroller 502 and configured to support a variety of system control and interface functions. For example, GPIO 510 may be used to receive manual input from a user (such as button presses) and to drive system indicators (such as LEDs) or control relays associated with actuators (such as valves or fans). In some implementations, portions of the GPIO line may also support biometric input devices, touchscreen input, or keyboard interfaces. GPIO 510 may also be part of the user interface or control panel of the modular ozone disinfection system 100, providing a direct physical interaction path for technicians 302, administrators 304, or other users. These GPIO-based controls enable on-site maintenance, mode switching, or test activation without the need for wireless or remote access.

[0145] One or more sensors 512 provide feedback information to the control system 500. These sensors include an ozone sensor 522 (for ambient or internal air detection), a temperature sensor 556 (for heater and environmental monitoring), and a humidity sensor 518 (critical to the dehumidification configuration 174). Data from the sensors 512 is processed by a microcontroller 502 to ensure safe operation, trigger cycle switching, or adjust set parameters.

[0146] For location-based control, the system includes a GPS module 514. In a geofencing implementation, when the system is moved outside a pre-authorized area, the controller 500 can disable ozone generation to prevent unauthorized or unsafe operation in regulated locations.

[0147] The electrolytic ozone generator 516 uses ion exchange material 534 and is activated and regulated by controller 500 to generate gaseous ozone for air treatment or liquid ozone 114 for water disinfection. Water enters the generator 516 through a fixed water tank, a replaceable water filter 126, or through an external water path controlled by pump and valve assemblies 128A and 128B, with pump and valve controller 520 managing the process.

[0148] Humidity sensor 518 is used to detect the humidity level in the environment or airflow channel and feeds the real-time data back to microcontroller 502. Microcontroller 502 can then adjust the operating behavior of dehumidification configuration 174 accordingly. The humidity sensor 518 can also be used to trigger moisture collection cycles and ensure that the dehumidification system operates under safe and efficient conditions.

[0149] The pump and valve controller 520 is responsible for managing the start-up, shutdown, and timing control of water pumps 128A and 128B, as well as all solenoid valves or check valves used for fluid switching. Its function is to precisely deliver water from the water tank configuration 172, dehumidification configuration 174, or water source configuration 176 to the electrolytic ozone generator 516 to ensure a stable and consistent ozone output.

[0150] Ozone sensor 522 is used to monitor residual ozone concentration. If an excessively high ozone concentration is detected during or after treatment, the system can stop ozone generation, direct airflow to the titanium dioxide coated surface 110, or activate fan controller 528 to accelerate dilution and circulation through fan / blower assemblies 104A, 104B, or 104C.

[0151] The dehumidification configuration 174 (including the condenser coil 124) is regulated by the dehumidification controller 524. This subsystem collects moisture from the air into the water collection container 108 and delivers it to the water tank configuration 172. Fluid flow and the heating element 168 are managed by the heating controller 554 to ensure the stability of ozone generation conditions.

[0152] The dehumidifier controller 524 is functionally associated with the dehumidifier 124, the fan or blower assembly 104A, and the water source housing 156 of the water tank or replaceable water filter 126. Based on signals from the humidity sensor 518 or controller logic, the dehumidifier controller 524 initiates moisture collection from the ambient air. It controls the operation of the condenser and the circulation of the blower, and ensures that the collected water is directed into the storage tank or water tank for use by the ozone generation subsystem.

[0153] In one example implementation, power supply 526 powers the core components of the modular ozone disinfection system 100, including microcontroller 502, ozone generator 516, fan assemblies 104A–C, water pumps 128A–B, heating element 168, and sensor 512. Power supply 526 can support various configurations: AC mains input (110–240V), DC input (e.g., 12V / 24V), rechargeable battery pack (for portable or off-grid applications), solar system (with integrated energy storage), or a hybrid mode switching between AC and battery backup. The power system may include current sensor 532 for monitoring load, enabling controller 500 to manage energy consumption and activate safe or energy-saving modes. In Internet of Things (IoT) supported configurations, communication interface 508 can report power status or alarms to remote resources 702 or devices 732, enabling real-time service and performance monitoring.

[0154] The fan controller 528 is functionally associated with one or more fan / blower assemblies 104A and 104B for regulating the intensity and direction of airflow through the purification configuration 170. It receives input from the controller 500 and the ozone sensor 522 to manage ozone diffusion, purification airflow circulation, and the catalytic oxidation phase. The controller can drive the fan in a variable speed or duty cycle manner depending on the disinfection mode.

[0155] A water-soluble ozone generator 530 (optionally housed within a removable piping connection housing 178) is used to convert water received via a fluid path into an ozone concentrate 114. It includes or is associated with an electrolytic ozone generator 516 and ion exchange material 534. In some embodiments, the generator 530 may be configured to deliver aqueous ozone to an internal ice maker or water dispenser for internal disinfection.

[0156] The optional 532 current sensor is used to monitor the performance and power load of critical subsystems such as fans, pumps, and heaters. Deviations in current changes can be used to detect maintenance problems or system failures in advance.

[0157] The ultraviolet (UV) light controller 534 is functionally associated with one or more UV lamp sources 108A and 108B for controlling the on-time and intensity of the UV light. In applicable embodiments, the UV light source is used to further decompose ozone or organic pollutants. The UV light controller 534 receives operating instructions from the controller 500 and may be interlocked with a door sensor or timer to prevent accidental UV exposure.

[0158] A level sensor 552 is disposed inside the water source housing 156 of the water tank or replaceable water filter cartridge 126 to detect the current water volume. This sensor may include upper and lower threshold detection to monitor capacity and depletion status. The controller 500 uses this feedback to prevent the electrolytic ozone generator 516 from operating dry and to trigger a replacement notification when the water tank needs to be replaced.

[0159] The heater controller 554 is functionally associated with the positive temperature coefficient (PTC) heater 168 and the temperature sensor 556. It receives commands from the controller 500 and, based on the received temperature data, starts, stops, or adjusts the heater. The heater controller 554 enables the system to regulate airflow or water temperature to improve disinfection performance, particularly when the oxidation process is optimized through thermal conditions.

[0160] In some implementations, an ultraviolet (UV) controller 528 and a UV lamp may also be provided to enhance the disinfection effect; however, in configurations where ozone and catalytic oxidation are the main treatment methods, this function can be omitted.

[0161] The above components together constitute an intelligent control framework with network awareness capabilities, enabling the system to achieve: - Automated processing loop; - Feedback-based adaptive ozone control; - Sensor-triggered safety shutdown; - Geofencing enforces control; - Remote monitoring and remote takeover control capabilities; and - Compliance record functionality for regulatory or quality assurance purposes.

[0162] This modular, IoT-integrated design allows the Modular Ozone Disinfection System 100 to be deployed in multiple fields—including walk-in cold storage and ice makers, air purifiers, toilet disinfection systems, catering service environments, and other diverse environments and application scenarios—while possessing complete traceability, auditability, and maintainability.

[0163] See Figure 8 The diagram illustrates the information technology system and network architecture associated with the modular ozone disinfection system 100. In one example implementation, the system is configured as an Internet of Things (IoT) platform, enabling one or more deployed disinfection systems to communicate in real-time with remote computing infrastructure via a global communication network 700 (e.g., the Internet). This networking capability allows the system to support centralized monitoring, distributed device group management, automatic alarms, service history, and location-based control functions, and is accessible to both local technicians and remote administrators.

[0164] This integrated communication architecture significantly enhances the reliability, safety, and maintainability of the modular ozone disinfection system 100, making it suitable for highly regulated application environments such as medical, food service, retail, transportation, and industrial sites, where consistent disinfection performance and auditable operational records are crucial.

[0165] The modular ozone disinfection system 100 includes a control system 500 equipped with a communication interface 508, enabling secure data transmission with one or more remote data processing resources 702. This remote resource can be a cloud server, a local enterprise system, or a hybrid infrastructure. Each remote server 702 may include an embedded microprocessor 704A, a storage module 708A, and a communication interface 710A, and is connected to a database 706A (storing disinfection / odor removal database 800). Database 800 stores critical operational and compliance data, such as account records, equipment installation locations, geofenced areas, ozone generator performance metrics, self-test results, technician operation logs, and system-generated notifications. This data can be used to generate maintenance plans, track regulatory compliance, and manage the hardware lifecycle of deployed systems.

[0166] Remote interaction with the system can also be achieved through one or more computing devices 732, including smartphones 732A, tablets 732B, or laptops and desktop computers 732C. Each computing device is equipped with a microprocessor (such as 704B or 704C), memory (708B or 708C), and database storage (706B or 706C), and a communication interface 710B or 710C to enable network access to the control system 500 and the remote server 702. The user interface displayed on the monitor 712B or 712C provides real-time visualization of system operation, maintenance status, and alarms; GPIO 714B or 714C supports external peripherals or inputs for technician-oriented software. Some devices may also include an onboard or built-in GPS module 716, a microphone, or a camera 718 for location marking or remote support diagnostics.

[0167] These computing devices can be powered by built-in rechargeable batteries or AC adapters 720B and 720C, depending on the device type and field usage requirements. Field technicians 302 and administrators 304 can use these mobile or desktop interfaces to view installed system records, access troubleshooting logs, initiate diagnostic tests, or execute remote commands, such as starting or stopping disinfection cycles, overriding alarms, or performing firmware updates.

[0168] In one example use case, technician 302 accesses the security control panel via tablet 732B. This interface displays a visual representation of the installation site, such as a floor plan 844 showing the locations of multiple deployed systems 100. The interface allows selection of different zone identifiers 'A' 846A, 'B' 846B, 'C' 846C, and 'D' 846D, each zone corresponding to a specific location within the facility, such as restrooms, dining areas, wards, or refrigeration equipment areas. Once selected, the interface displays detailed system information, including the current system location 838, operating status 840 (e.g., disinfecting or standby), and consumable status 842 (e.g., remaining water percentage, ozone generator health status, or replacement reminder).

[0169] Through this integrated information technology system, the modular ozone disinfection system 100 provides proactive alarms, location-based compliance verification (e.g., geofencing control via GPS 514), and local and remote access to key performance indicators. The internet-connected architecture enables administrators to manage large-scale device clusters across multiple sites, while allowing field technicians to efficiently diagnose, maintain, or verify the proper functioning of each device. Furthermore, firmware updates, new processing modes, or response strategies can be pushed to the system from the cloud, eliminating the need for manual intervention at the hardware level.

[0170] See Figure 9An example of a disinfection / deodorization database structure 800 for a modular ozone disinfection system 100 is shown. This database structure 800 is used to organize, track, and manage various operational, location, and maintenance-related data records of the system 100 across its deployed equipment portfolio. In one example implementation, the database 800 may be hosted on a remote data processing resource 702 or accessed by a technician 302 or administrator 304 using computing devices 732A–C. The database 800 may be implemented using various database technologies, including SQL, MySQL, MariaDB, Oracle, MS Access, flat file structures, network-attached storage, or other suitable forms.

[0171] In database 800, account records 802 store user credentials, service level information, and customer billing or licensing data. Location records 804 associate each deployed system 100 with a specific geographic or facility location and can be integrated with geofencing records 806 to establish virtual boundaries for monitoring disinfection program compliance or verifying proximity access controls. Device records 808 contain metadata for each system 100, including serial number, model configuration (e.g., purification configuration 170, water storage configuration 172, etc.), operational history, and hardware lifecycle status.

[0172] The self-test result 810 is automatically recorded by the system controller 500, including system health check data such as ozone sensor readings, liquid level thresholds, error flags, and the status of replaceable components (such as replaceable water filter 126 and electrolytic ozone generator 516). This data is timestamped and associated with the corresponding device record 808.

[0173] Technician logs 812 are used to track operational interactions by service personnel 302, including maintenance access, component replacement, software updates performed via computing device 732, and remote diagnostics. These logs also include remote diagnostics performed via computing device 732. Notification logs 814 are used to record automated alarms sent to technicians or administrators, such as low water level warnings, abnormal ozone production, expired water cartridge reminders, or maintenance alerts. These logs may also include ozone readings, water cartridge status, and customizable notification information.

[0174] Importantly, the ozone generator log 816 is used to maintain a detailed record of the ozone generating component itself, including the installation date, generator lifespan estimate, historical performance trends, and humidity-related performance adjustments that affect efficiency. These records may also include a fault log and a projected replacement schedule based on usage analysis.

[0175] The modular nature of the system architecture allows the database 800 to dynamically adapt to various implementation methods, including those integrating dehumidification configuration 174, water supply configuration 176, or IoT sensor components. This integration of structured data enables the system to achieve scalable service logistics, operational transparency, and optimized management of the lifecycle of each modular ozone disinfection system 100, allowing for deployment in both public and private environments.

[0176] See Figure 10 This illustration shows an example of a technician using a software application to monitor and maintain a modular ozone disinfection system 100. In one example implementation, a technician 302 uses a computing device 732 (which could be a smartphone 732A, a tablet 732B, or a laptop / desktop computer 732C) to interact with the user interface of a service or maintenance application to manage the functions of the system 100. The computing device 732 communicates with a remote data processing resource 702 via a global network 700 to obtain system-level diagnostics and operational insights, while simultaneously synchronizing service records and usage data in real time.

[0177] The first screenshot 838 shows the installation location and technical details related to a specific modular ozone disinfection system 100, including the model, serial number, system configuration (e.g., purification configuration 170, water storage configuration 172, and control system 500), installation date, and current firmware version.

[0178] The second screenshot 840 shows the operating status interface, including system mode (e.g., purification, disinfection, idle), ozone generation activity, OH generation status, aqueous ozone flow, and other sensor readings (e.g., temperature, humidity, or ozone concentration). This interface allows technicians 302 to confirm whether system 100 is operating within the set parameter range and can selectively initiate test cycles or diagnostic functions.

[0179] The third screenshot, 842, shows the consumable status information for the water source housing 156 and the electrolytic ozone generator 516. In one implementation, the service application can display estimated remaining service life, usage history, last replacement date, and alarm indications for replacement or replenishment. This operational status information helps enable preventative maintenance and reduces the risk of system downtime.

[0180] Figure 10A floor plan 844 is also shown, corresponding to a geofenced facility or environment, such as a hospital, office building, or restaurant. In floor plan 844, multiple monitored areas are represented as monitoring area A 846A, area B 846B, area C 846C, and area D 846D. Each of these areas is associated with an installed modular ozone disinfection system 208. Technicians 302 can assess the installation location and operational status of each device, track changes in its health status, and verify compliance with disinfection coverage requirements by viewing the map interface.

[0181] This diagram highlights the service layer visualization capabilities provided by the built-in Internet of Things (IoT) capabilities of System 100. Through computing device 732, technicians 302 can manage locally installed and distributed devices located at multiple geofenced locations, enabling faster fault diagnosis, easier system configuration, firmware updates, and real-time verification of operational integrity. This modern cloud-connected service platform offers significant advantages over traditional air purification systems, which typically lack remote maintainability, integrated digital service records, and automated consumables management capabilities.

[0182] See Figure 11 An example implementation of a floor plan 844 for monitoring a geofenced or geolocated room space where a modular ozone disinfection system 100 / 500 has been installed is shown. In this implementation, each room or designated area is assigned a monitored area 846A–D, which may correspond to an operating room, laboratory, clean room, or other controlled environment.

[0183] Each monitored area can be associated with a room identifier 848A–D for easy tracking and system association, and can be identified by an installation system identifier 850 indicating the specific modular ozone disinfection system 100 / 500 deployed in that room or area. These identifiers 848A–D can be managed by a remote data processing resource 702 and synchronized with a local computing device 732 used by technicians 302. In some implementations, these identifiers and associated metadata are visualized through software applications or dashboards running on the computing device 732, providing real-time information on device location, operational status, and geofence boundaries.

[0184] The modular ozone disinfection system 100 / 500, installed in each geofenced room space, operates based on a room-specific disinfection plan or sensor-triggered conditions. By integrating GPS 514 or other location-aware technologies, it enables location-based geofencing logic, supporting location analysis, automatic alarms, and compliance tracking. For example, the system can record the time a technician enters a geofenced area, triggering pre-disinfection confirmation and initiating a disinfection cycle. Upon completion, the system can record and upload cycle metadata, such as duration, ozone level, and surface coverage report, to database 706A.

[0185] Technician 302 can use the geolocation interface of floor plan 844 to monitor multiple disinfection areas, confirm disinfection completion, and respond to anomalies (such as missed loops or system malfunctions). This approach enhances operational visibility and centralizes the management of distributed ozone disinfection equipment, facilitating unified management across facilities or parks, while also strengthening record-keeping capabilities for oversight and internal auditing.

[0186] See Figure 12 This paper illustrates an example of a method for ozone treatment of air using a modular ozone disinfection system. The method emphasizes a self-contained ozone generation and purification process that utilizes a replaceable water filter to generate ozone gas for disinfection and employs a titanium dioxide-coated surface for safe purification. This method aims to achieve reliable surface and air treatment cycles in a closed environment while maintaining compliance with human exposure safety limits.

[0187] The method begins at step 1002, where a replaceable water filter cartridge 126 is inserted into a water tank configuration 172, which is functionally connected to a purification configuration 170. In one embodiment, the replaceable water filter cartridge 126 may be pre-filled and sealed during manufacturing; in other embodiments, a technician 302 may manually fill the water tank using deionized water, distilled water, or electrolyzed enhanced water. The water source housing 156 ensures compatibility and prevents incorrect insertion through alignment structures such as the outline 160 and alignment protrusions 162.

[0188] In step 1004, an electrolytic ozone generator 516, fluidly connected to the water tank configuration 172, is activated to generate ozone gas from the water. The electrolytic ozone generator 516 utilizes ion exchange material 534 to separate oxygen and hydrogen molecules during electrolysis, thereby forming high-purity ozone suitable for controlled disinfection applications.

[0189] In step 1006, the generated ozone is introduced into the purification configuration 170 and mixed with the circulating airflow. This mixed gas creates an oxidizing environment within the purification configuration housing, thereby rapidly neutralizing pollutants, microbial particles, and other impurities in the air.

[0190] In step 1008, the oxidizing gas flow is directed through a titanium dioxide-coated surface 110 located within the purification configuration 170. This titanium dioxide coating surface promotes a photocatalytic reaction, thereby chemically neutralizing residual ozone and other oxidizing substances. This step helps reduce ozone concentration while maintaining disinfection effectiveness. This step is particularly advantageous because it addresses the lack of an internal ozone removal mechanism in existing technologies, which could otherwise lead to prolonged ozone residue in the treated environment and pose safety hazards.

[0191] In step 1010, once the ozone concentration has been sufficiently reduced, the treated airflow is discharged from the modular ozone disinfection system 100. This purification system is configured to ensure that the ozone concentration in the discharged air is below acceptable human exposure limits, thereby guaranteeing a safe return to occupied spaces.

[0192] See Figure 13 This paper illustrates another example of a method for treating air ozone using a modular ozone disinfection system. This method is particularly suitable for applications employing an integrated dehumidification configuration 174, which autonomously extracts moisture from ambient air, allowing the system to operate without an external water supply. This method achieves ozone generation and air disinfection while ensuring that residual ozone is effectively reduced before being released back into the environment. The method begins at step 1102, where moisture is extracted from ambient air via the dehumidification configuration 174.

[0193] In step 1102, the dehumidification configuration 174 (which may include a fan / blower 104A, a condenser coil 124, and a water collector 108) draws in ambient air, condenses the moisture therein, and collects the water for internal use. This step enables the system to generate ozone without the need for an external or manual water source.

[0194] In step 1104, water extracted from ambient air is transferred from collection tank 108 to water tank configuration 172. This water transfer can be by gravity flow, pumping, or other suitable methods. In various embodiments, water tank configuration 172 can be a fixed internal water tank or a housing structure for receiving replaceable water filter cartridge 126.

[0195] In step 1106, the electrolytic ozone generator 516 is fluidly connected to the water tank configuration 172 and uses the water to generate ozone gas. The ozone generator 516 uses ion exchange material 534 to convert water into ozone gas through electrolysis. This process may simultaneously produce small amounts of hydrogen and oxygen as byproducts.

[0196] In step 1108, ozone gas is introduced into the purification configuration 170 and mixed with airflow drawn in from the surrounding environment. This mixing process creates an oxidizing environment within the system, treating and disinfecting the air. The air circulation subsystem 104 (including a fan) ensures continuous airflow between the internal components.

[0197] In step 1110, the ozone-treated airflow is passed through a titanium dioxide-coated surface 110 located inside the purification configuration 170. This titanium dioxide surface 110 promotes a photocatalytic reaction, thereby chemically reducing the content of residual ozone and other oxidizing substances, thus improving safety and preparing for air recirculation.

[0198] In step 1112, the treated airflow is discharged back into the environment. Since the photocatalytic reaction has reduced the ozone concentration to within the applicable human exposure safety limits (e.g., 0.1 ppm (8-hour TWA) as specified by OSHA), the discharged air is safe for use in environments where people are present.

[0199] Figure 14 This paper presents a method for continuous ozone disinfection using a water source configuration 176. This method is particularly suitable for applications requiring long-term continuous operation without frequent manual water replenishment, such as food refrigeration equipment, laboratory cold storage, or medical-grade refrigeration environments. This method integrates automatic ozone generation and purification functions through a continuous external water supply.

[0200] In step 1202, the water source configuration 176 is connected to the external water supply system.

[0201] In step 1204, water from water source configuration 176 is delivered to water tank configuration 172. In one embodiment, the water may first enter collection tank 108 as a buffer medium; in other embodiments, it may enter the water tank in water tank configuration 172 directly. This structure provides the ability to be flexibly configured according to installation conditions.

[0202] In step 1206, the electrolytic ozone generator 516 uses received water, which may be optimized or filtered, to generate ozone gas. The generator 516 may include or incorporate ion exchange material 534 to optimize the water chemistry and improve electrochemical reaction efficiency, thereby enhancing the stability of ozone generation. The generated ozone is then directed to purification configuration 170.

[0203] In step 1208, the generated ozone is introduced into the airflow of the purification configuration 170 to create a strong oxidizing environment. This oxidizing atmosphere can effectively eliminate bacteria, viruses, and odor compounds in the air, and is especially suitable for environments with high requirements for air cleanliness.

[0204] In step 1210, the ozone-treated gas stream is exposed to an ozone-neutralizing surface, such as a titanium dioxide coating structure disposed in the gas stream path. This exposure process promotes photocatalytic oxidation or catalytic decomposition of residual ozone, thereby reducing the ozone concentration to a level that meets applicable human exposure safety limits.

[0205] In step 1212, the treated and neutralized airflow is discharged from the modular ozone disinfection system 100. At this stage, the oxidant concentration in the airflow is no longer elevated and can be safely returned to spaces where people may enter, thus ensuring user safety while maintaining effective disinfection. This is especially suitable for idle or unoccupied operating cycles.

[0206] This method embodies a robust and autonomous disinfection solution suitable for continuous operation environments, which can reduce maintenance burden and increase system uptime without compromising safety.

[0207] Figure 15 An example embodiment of a method for performing disinfection using a modular ozone disinfection system 100 is shown, which can be used interchangeably with other methods of the present invention. This method emphasizes modular and scalable design, supporting compact installation, automated cycle control, and environmental sensing capabilities. The steps are applicable to various system configurations, including fixed water tanks, replaceable water filters, dehumidified water supply systems, and continuous external water supply systems.

[0208] In step 1302, the operation of the purification component can be started by the controller 500, which is used to adjust the fan speed and the ozone generation process.

[0209] During operation, the controller 500 initiates the purification configuration 170 and initializes the air circulation subsystem, including activating one or more fans to begin airflow within the system. Simultaneously, the controller performs startup diagnostics, verifies the status of each component, and pre-adjusts ozone generation parameters based on the current environmental input or a preset operating configuration file. Fan speed adjustment can be used to adjust the treatment intensity and operating cycle for different space requirements.

[0210] In step 1304, the purification configuration 170 and the water tank configuration 172 are installed in the same housing in a vertically stacked manner. This vertical structure allows water to flow from the water tank (such as a fixed water tank or replaceable water filter 126) to the electrolytic ozone generator 516 under gravity, thereby reducing reliance on pressurized pumping mechanisms. Simultaneously, this compact structure facilitates modular maintenance, allowing both the liquid and gas circuit components to be inspected without completely disassembling the housing, and is suitable for wall-mounted or space-constrained installation environments.

[0211] In step 1306, ozone sensor 522 monitors the ozone concentration of the treated airflow before it is discharged. This step ensures that the residual ozone level is below regulatory exposure limits (e.g., OSHA PEL or ACGIH TLV), thereby guaranteeing that the discharged air can safely enter occupantly occupied environments. Sensor data can be used to adjust fan operation, ozone generator duty cycle, or trigger internal ozone neutralization structures, such as titanium dioxide coated surface 110 or manganese dioxide surface 112.

[0212] In step 1308, the system executes a user-selected disinfection program stored in the memory 504 of the controller 500. These programs can be pre-set or custom-defined, and can define operating parameters such as cycle time, ozone output rate, purification duration, and sensor feedback thresholds. Technicians 302 or administrators 304 can remotely access and select these programs via a local interface (e.g., display 506 or GPIO 510) or via a connected computing device 732.

[0213] In step 1310, the system utilizes the dehumidification assembly 174 to operate the condenser coil 124, collecting moisture from the surrounding air. A fan 104A guides ambient air through the coil, during which moisture in the air condenses and drips into the collection tank 108. This water is then directed to the water tank configuration 172 for use by the electrolytic ozone generator 516. This step is particularly advantageous for autonomous systems or systems deployed in environments with limited water supply.

[0214] In step 1312, the controller 500 switches between an ozone generation mode and a purification mode. In ozone generation mode, gaseous ozone is generated by electrolyzing water and mixed with circulating air to perform disinfection. In purification mode, airflow is directed through a catalytic surface such as titanium dioxide 110 to reduce the residual ozone concentration. The controller can switch between these modes based on elapsed time, ozone concentration, or completion of a preset treatment cycle.

[0215] In step 1314, the treated air is discharged through an air outlet located in the purification configuration 170. This outlet is configured to discharge air that has undergone system oxidation and purification stages and meets human exposure safety standards. The direction, distribution pattern, and speed of the discharged airflow can be controlled to maximize spatial coverage while maintaining low noise and low energy consumption.

[0216] In step 1316, the level sensor 552 monitors the water level in the water tank configuration 172. When the water level falls below a critical threshold, the system can suspend ozone generation and notify the user or technician. In some configurations, the sensor can also be used to manage the incoming water from the water source configuration 176 or to initiate water replenishment from the dehumidification collection tank 108.

[0217] See Figure 16 This paper illustrates an example of a method for purifying air in refrigerated spaces using an ozone-based disinfection system. In one exemplary embodiment, the method aims to maintain high air quality inside refrigerated environments such as ice makers, walk-in cold storage facilities, and household refrigeration equipment. A key advantage of this invention is the internal reduction of ozone concentration through photocatalytic surfaces, thereby achieving disinfection without releasing harmful ozone levels into the food storage environment. This makes the method particularly suitable for applications where air disinfection must be carried out without compromising food safety or personnel access. The method begins at step 1402, initiating a purification mode via an operation controller, simultaneously activating the electrolytic ozone generator and the air circulation subsystem.

[0218] In step 1404, gaseous ozone is generated from water using an electrolytic ozone generator. This generator may contain ion-exchange materials to improve the purity and efficiency of ozone generation, thereby ensuring stable oxidizing power for disinfection.

[0219] In step 1406, gaseous ozone is mixed with airflow from the refrigerated space inside the shell to create an oxidizing environment in which microorganisms, bacteria, and viral pollutants in the airflow can be neutralized by the oxidizing properties of ozone.

[0220] In step 1408, the oxidizing gas stream is guided through the surface of the titanium dioxide coating. The titanium dioxide coating promotes photocatalytic reactions, thereby accelerating the decomposition of residual ozone and volatile compounds. This step serves two purposes: (1) to further sterilize the gas stream; and (2) to reduce the ozone concentration to a level safe for human health before emission.

[0221] In step 1410, the treated airflow is returned to the refrigerated space. At this stage, the ozone concentration in the airflow has been reduced to a level that meets applicable human exposure safety limits, such as those defined by OSHA or international food safety standards. This step ensures that the disinfection process can be safely performed without exposing stored items or users to high concentrations of ozone.

[0222] See Figure 17This paper illustrates an example of a phased treatment cycle method for purifying air in a refrigerated space using an ozone-based disinfection system. Unlike continuous purification methods, this implementation includes clearly distinguished disinfection and purification modes, allowing the system to temporarily increase ozone concentration within the refrigerated space for surface-level disinfection before safely restoring air quality for re-entry or food storage. This dual-mode approach achieves more efficient microbial reduction while maintaining compliance with human exposure safety standards. The method begins at step 1502 by operating the ozone-based disinfection system in disinfection mode, i.e., by activating an electrolytic ozone generator to produce gaseous ozone from water.

[0223] In step 1504, the generated gaseous ozone is introduced into the refrigerated space and maintained for a set disinfection time. During this period, the ozone concentration in the environment is increased to above the normal operating threshold to deeply oxidize the internal surfaces, shelves, storage compartments, and other components exposed to the air. This disinfection time is controlled by precise timing or sensors to ensure disinfection effectiveness while avoiding prolonged overexposure.

[0224] In step 1506, the system switches to purification mode via controller 500. This controller may be pre-programmed with a disinfection program or automatically determine when to switch modes based on sensor inputs such as ozone concentration data. This switch marks the end of the high-concentration ozone exposure phase and the beginning of the internal air neutralization process.

[0225] In step 1508, air from the refrigerated space is recirculated through a purification assembly comprising a titanium dioxide-coated surface disposed in the airflow path. As the air flows over this surface, the titanium dioxide promotes a photocatalytic oxidation reaction, thereby chemically degrading residual ozone and neutralizing volatile organic compounds and other oxidizing substances that may have accumulated during the disinfection phase.

[0226] In step 1510, the ozone concentration in the recirculated airflow is reduced to a level that meets applicable human exposure safety limits. After treatment, the airflow is vented back to the refrigerated space. The system ensures that the recirculated air is safe for personnel access and food storage, thereby supporting periodic disinfection operations without compromising safety or regulatory compliance.

[0227] See Figure 18This paper illustrates an example of a method for purifying air in a refrigerated space using an ozone-based disinfection system. The method utilizes a manganese dioxide treatment module to generate hydroxyl radicals to enhance oxidation performance. This method differs from previous embodiments in that it replaces the disinfection mechanism with direct ozone exposure with the use of secondary oxidants (OH radicals), which provide strong microbial neutralization capabilities while reducing the regulatory complexities associated with ozone. Furthermore, this method allows for the simultaneous treatment of air and water within the same refrigerated environment, making it particularly suitable for closed food storage systems, combined ice-making and dispensing equipment, and similar applications. The method begins at step 1602, where gaseous ozone is generated from water using an electrolytic ozone generator housed within the housing.

[0228] In step 1602, the system activates the electrolytic ozone generator 516 to generate ozone gas by electrolyzing water from the water tank configuration 172 or the water source configuration 176. This generator may include or operate in conjunction with ion exchange material 534 to ensure suitable water quality conditions for the generation of high-purity ozone. The generator is housed within a modular housing of the system to support compact integration within the refrigeration equipment.

[0229] In step 1604, the generated gaseous ozone is directed to the manganese dioxide treatment module 112, which is also located within the housing. When ozone molecules pass through the surface of manganese dioxide, a catalytic reaction occurs, generating hydroxyl radicals (•OH). These radicals are highly reactive oxidants that can decompose microbial cell walls, odors, and biofilm formations within a short contact time without leaving harmful residues.

[0230] In step 1606, air rich in hydroxyl radicals is circulated and delivered to the enclosed refrigerated space. A fan or blower in the air circulation subsystem 104 distributes this reactive air throughout the space, achieving uniform treatment of the internal air volume and exposed surfaces. Because hydroxyl radicals have an extremely short lifetime, they react rapidly within the space and are not easily sustained or accumulated. Therefore, this method, while ensuring high efficiency, is still suitable for enclosed or intermittently used environments.

[0231] In step 1608, aqueous ozone generated by the same electrolytic ozone generator is directed to the water path used by an ice maker or water dispenser associated with the refrigerated space. This water path may include an ice tray, a water storage container, an outlet pipe, or a valve assembly 418. Aqueous ozone acts as an auxiliary disinfectant in the water system, helping to reduce bacterial growth, scale formation, and taste or odor problems, thereby improving the hygiene of the water storage or supply components.

[0232] See Figure 19A illustrates an example of a method for purifying air in a refrigerated space using a modular ozone-based disinfection system 100. This method emphasizes intelligent adaptive disinfection behavior in ice makers and refrigerator compartments, managing ozone-based air and water treatment through integrated automation and sensor-driven control functions. The method supports enhanced safety, water system disinfection, and user-programmable disinfection procedures that dynamically respond based on detected ozone levels and operating status.

[0233] In step 1702, aqueous ozone generated by the electrolytic ozone generator 516 is introduced into a water pipe via the aqueous ozone circuit 418. This water pipe can supply water to the ice maker 232 or the refrigerator water dispenser. Introducing ozone water 114 into these water circuits provides a disinfection effect, reduces the accumulation of microorganisms in the water system, and improves the hygienic quality of the ice 420 and drinking water.

[0234] In step 1704, the modular ozone-based disinfection system 100 maintains continuous purification during the normal operation of the refrigeration equipment 210. The system 100 operates in a low-ozone, continuously circulating air purification mode, achieving continuous air quality improvement while ensuring that the ozone concentration meets the regulatory safety thresholds for human-occupied environments.

[0235] In step 1706, the treated purified air is introduced into the internal storage compartment or chamber of the ice maker 232. This airflow 408 is treated with titanium dioxide photocatalytic oxidation and ozone neutralization, which helps to inhibit the accumulation of microorganisms and the formation of biofilm on the internal ice-making surface, thereby maintaining a clean state.

[0236] In step 1708, sensor 512 (e.g., ozone sensor 522) detects the ozone concentration in the refrigerated space. This real-time ozone concentration monitoring enables system 100 to ensure air safety, manage switching between disinfection and purification modes, and prevent exposure to excessively high ozone concentrations.

[0237] In step 1710, when the ozone concentration is detected to exceed a preset threshold, the operation of the electrolytic ozone generator 516 is reduced or suspended. This dynamic control reduces risk and helps to meet ozone exposure limits related to occupational safety and food safety.

[0238] In step 1712, controller 500 records operational data related to ozone generation or purification. This data may include timestamps, ozone levels, disinfection cycle durations, or system mode switching information. The recorded data is used for compliance tracking, maintenance audits, and long-term evaluation of system performance.

[0239] In step 1714, aqueous ozone and gaseous ozone are simultaneously generated using an electrolytic ozone generator 516 and introduced, either separately or simultaneously, into the same or different water paths of the ice maker or distributor. This simultaneous generation method allows air and water paths to be disinfected simultaneously through a shared electrochemical ozone generation platform.

[0240] In step 1716, the controller 500 automatically switches the system from disinfection mode to purification mode based on a stored timer. This mechanism ensures that after the predetermined disinfection time has elapsed, the system degrades ozone and purifies the air through the titanium dioxide coating surface, thereby restoring the ozone level to a safe threshold for human use.

[0241] In step 1718, the user is allowed to select stored cleaning or disinfection programs via a control panel or other user interface, such as a dashboard, touchscreen, or application-based interface. These programs can define operating parameters, such as duration, airflow intensity, water disinfection sequence, and ozone generation intensity, to provide flexible configuration to meet different refrigeration environments and compliance requirements.

[0242] See Figure 19 B illustrates an exemplary embodiment of a method for purifying air in a refrigerated space using a modular ozone-based disinfection system 100, which is interchangeable with other methods of the present invention. These embodiments demonstrate enhanced safety, precise control, and system flexibility in the management of airflow and water disinfection within an ozone treatment cycle.

[0243] The method begins at step 1720, in purification mode, by directing recirculated air to the titanium dioxide-coated surface 410 within the housing. This surface is used to promote a photocatalytic oxidation reaction, thereby reducing residual ozone in the airflow to levels that meet applicable human exposure safety limits.

[0244] In step 1722, the system emits a visual or auditory signal to indicate that the disinfection mode is in operation. This function is used to remind the user that a high-concentration ozone disinfection cycle is currently in progress and that entry into the refrigerated space should be avoided.

[0245] In step 1724, the system records disinfection cycle parameters, such as start time, ozone concentration curve and duration, and stores them in a local or remote system for traceability, compliance monitoring or quality assurance.

[0246] In step 1726, the door locking mechanism is automatically activated during the disinfection cycle to lock the cold storage space, thereby preventing personnel from being accidentally exposed to ozone environments exceeding the safety threshold.

[0247] In step 1728, the system will automatically unlock the door of the refrigerated compartment only when the sensor confirms that the concentration of gaseous ozone has been reduced to a preset or legally prescribed safe level for human re-entry.

[0248] In step 1730, the aqueous ozone 114 generated in this cycle is introduced into the water pipes, ice trays or water tanks associated with the ice maker 232 or the refrigerator water dispenser, thereby achieving effective water-based disinfection of components that come into contact with consumables such as ice or water.

[0249] In step 1732, the housing is installed on the inner wall of the refrigerator or ice maker cavity. This embedded installation method enables efficient internal circulation of ozone-treated or purified air and achieves integrated disinfection without occupying external space.

[0250] These methods and steps collectively achieve safe, automated, and comprehensive disinfection of the air and water pathways in the refrigeration equipment 210, making it particularly suitable for applications such as hospital cold storage, commercial walk-in cold storage, and ice makers in food service environments.

[0251] See Figure 20 This paper illustrates an example of a method for disinfection using a modular ozone-based disinfection system 100 with a replaceable water filter cartridge 126. This method provides a compact, low-maintenance ozone air purification solution, particularly suitable for environments with limited water supply infrastructure. Plug-and-play operation is enabled using a pre-filled, sealed water storage unit in the replaceable water filter cartridge 126, and ozone is generated electrochemically for precise, on-demand disinfection cycles. Integration of ultraviolet (UV) light with the titanium dioxide (TiO2) coated surface 110 promotes photocatalytic oxidation, ensuring that residual ozone in the treated airflow 408 is neutralized before being released into the surrounding environment. The method begins at step 1802, where the replaceable water filter cartridge 126, containing the sealed water storage unit, is inserted into the housing of the modular ozone-based disinfection system 100.

[0252] In step 1804, water from the inserted replaceable water filter cartridge 126 is supplied to the electrochemical ozone generator 516. In one exemplary embodiment, the generator utilizes ion exchange material 534 to support the generation of high-purity ozone gas from the input water. A fluid passage between the replaceable water filter cartridge 126 and the ozone generator 516 is established via internal tubing 136 and a fluid connection port that can be aligned when the water cartridge is inserted.

[0253] In step 1806, the electrochemical ozone generator 516 produces gaseous ozone from the supplied water. This system is capable of generating a controlled concentration of ozone suitable for enclosed indoor environments. The generated ozone gas is then introduced into an airflow within the housing.

[0254] In step 1808, an internal air circulation subsystem (which may include one or more fans 104A / B) is used to guide airflow through the housing, mixing the airflow with generated ozone gas to create an oxidizing environment. This ozone-air mixture is distributed to the internal treatment surfaces to remove microorganisms and odors.

[0255] In step 1810, the oxidizing environment is exposed to the titanium dioxide coating surface 110. The surface is irradiated by ultraviolet (UV) light sources 108A and / or 108B, thereby promoting a photocatalytic oxidation reaction that decomposes residual ozonochemicals into oxygen, while simultaneously decomposing volatile organic compounds and microbial contaminants present in the gas stream.

[0256] In step 1812, the treated and chemically neutralized airflow is discharged from the housing through the exhaust duct. This process ensures that the ozone concentration in the exhaust air is reduced to a level that meets applicable human exposure safety limits, thereby enabling the system to be used safely in occupied environments.

[0257] In step 1814, the controller 500 (including a microcontroller 502, a memory 504, a display 506, and a communication interface 508) operates the electrochemical ozone generator 516 and the air circulation subsystem. The controller manages system functions based on one or more stored operating modes, which may include user-selected settings, time-based disinfection cycles, or remote trigger commands via an Internet of Things (IoT) connection. The controller can also record system operating data and trigger maintenance reminders when a water tank is depleted or other conditions are detected.

[0258] refer to Figure 21 This paper illustrates an example of a method for disinfection using a modular ozone disinfection system with a replaceable water filter. Unlike traditional fixed tank systems, this implementation integrates a positive temperature coefficient (PTC) heating element to regulate the airflow before ozone mixing, thereby enhancing oxidation performance. This modular structure, combined with thermal regulation, allows for a more flexible and compact disinfection solution in enclosed environments where airflow dynamics and temperature affect efficiency. The method begins at step 1902, where a replaceable water filter with a sealed tank is inserted into the disinfection system housing.

[0259] In step 1904, water from the replaceable water filter cartridge is supplied to an electrochemical ozone generator located within the housing. This fluid transfer is achieved via an integrated fluid connector that automatically engages upon insertion of the water cartridge.

[0260] In step 1906, the electrochemical ozone generator produces gaseous ozone from the supplied water. This electrochemical generator may include ion exchange material 534 and electrodes, and produces ozone gas through an electrolytic reaction without the need for any chemical additives.

[0261] In step 1908, the positive temperature coefficient (PTC) heating element 168 is activated. This element, located within the housing, heats the incoming gas flow, thereby enhancing ozone gas diffusion and improving the subsequent photocatalytic and oxidation reactions.

[0262] In step 1910, the regulated gas flow is mixed with ozone gas to create an oxidizing environment. This oxidizing mixture circulates within the housing for further treatment of the internal catalytic surfaces.

[0263] In step 1912, the oxidizing environment is exposed to the titanium dioxide coating surface 110 located within the housing. This exposure promotes a photocatalytic reaction that decomposes ozone and other volatile organic compounds, thereby reducing the ozone concentration to a level that meets applicable human exposure safety limits.

[0264] In step 1914, the treated airflow is discharged from the casing, at which point the airflow has reached a state where it can be safely returned to the surrounding environment. This exhaust process can be assisted by one or more fans (104A, 104B) and controlled by the system.

[0265] In step 1916, the controller 500 coordinates the control of the electrochemical ozone generator 516, the PTC heating element 168, and the air circulation subsystem. This coordinated control enables the system to maintain optimized temperature and ozone generation parameters, execute pre-stored disinfection modes, and ensure that safety threshold requirements are always met.

[0266] refer to Figure 22 An example of a method for disinfection using a modular ozone disinfection system 100 with a replaceable water filter cartridge 126 is shown. This embodiment emphasizes enhanced monitoring and safety interlocking capabilities, intelligently tracking water tank status and system operation to support automatic shutdown and remote communication functions. These features are particularly important for environments requiring strict adherence to air quality safety limits and equipment maintenance specifications.

[0267] The method begins in step 2002, where a replaceable water filter cartridge 126 with a sealed water tank is inserted into the water source housing 156 of the modular ozone disinfection system 100. The water source housing 156 includes keyed alignment structures, such as alignment ridges 162 and sealing caps 158, to ensure correct installation orientation and prevent contamination.

[0268] In step 2004, water is supplied from the replaceable water filter cartridge 126 to the electrochemical ozone generator 516. The generator may include ion exchange material 534 and is disposed inside the water source housing 156.

[0269] In step 2006, the electrochemical ozone generator 516 uses the supplied water to generate gaseous ozone for air disinfection.

[0270] In step 2008, the air circulation subsystem (including one or more fans 104A) guides airflow 402 within the water source housing 156 to mix with the generated gaseous ozone, forming an oxidizing environment 404.

[0271] In step 2010, the oxidizing environment is directed through a titanium dioxide-coated surface 110 located within the water source housing 156. This surface 110 is used to promote a photocatalytic oxidation reaction, reducing the ozone concentration to a level that meets applicable human exposure safety limits.

[0272] In step 2012, the treated airflow 408 is discharged from the water source housing 156 into the surrounding environment.

[0273] In step 2014, the controller 500 (including the microcontroller 502, the memory 504, and the communication interface 508) monitors the usage of the replaceable water filter 126 based on the operating activities of the electrochemical ozone generator 516.

[0274] In step 2016, the system determines the water tank replacement status based on the monitored generator operation activities and tracked water consumption. When it is determined that the water tank is depleted or has been removed, the system proceeds to step 2018, automatically disabling the electrochemical ozone generator 516 to prevent further operation, thereby ensuring user safety and maintaining system performance.

[0275] Finally, in step 2020, the controller 500 transmits the operating status data to the remote data processing resource 702 or computing device 732 via the communication interface 508. The transmitted data may include water tank status alarms, remaining operating time, or any fault conditions detected during operation.

[0276] This smart water box tracking method improves on-site maintainability and compliance monitoring capabilities, making it particularly suitable for mission-critical environments such as hospitals, laboratories, and commercial food preparation facilities.

[0277] refer to Figure 23 A, illustrates an example embodiment of a method for disinfection using a modular ozone disinfection system 100 with a replaceable water filter 126, which is interchangeable with other methods of the present invention. This method emphasizes advanced water tank validation, intelligent environmental regulation, and enhanced photocatalytic oxidation technology through a synchronized subsystem. The method utilizes integrated sensors and controllers to adjust the operational response based on user input and environmental feedback, thereby providing greater safety, accuracy, and modularity. The method begins at step 2102 by irradiating the ozone-containing internal airflow with the activation of ultraviolet (UV) lamps 108A / 108B located within the housing. This UV irradiation enhances air disinfection and promotes photocatalytic oxidation of internal treated surfaces such as the titanium dioxide coating 110, thereby further reducing ozone levels and neutralizing pathogens.

[0278] In step 2104, the stored operating modes include at least one of the following: timed disinfection cycle, sensor-triggered activation cycle, or remotely initiated command. These modes can be selected by the controller 500, enabling the system to adapt to different environments and usage plans.

[0279] In step 2106, the correct alignment of the replaceable water filter 126 is verified by the keyed engagement structure 162 between the replaceable water filter 126 and the water source housing 156. These structures prevent incorrect installation and ensure proper connection of fluid and electrical interfaces, thereby guaranteeing consistent disinfection output.

[0280] In step 2108, after the disinfection cycle is completed, the airflow is recirculated within the housing via the air circulation subsystem 104A / B. This helps reduce internal ozone levels, ensures that no residual ozone is released into the external environment, and keeps emissions within safe limits for human exposure.

[0281] In step 2110, operational status data is recorded to remote data processing resource 702, which may include information such as operating cycles, ozone generation history, and maintenance alarms. This data can be used for compliance monitoring, equipment group maintenance tracking, or remote diagnostics.

[0282] In step 2112, the system adjusts the activation of the positive temperature coefficient (PTC) heating element 168 according to the ambient temperature or humidity conditions detected by the sensor 512, thereby improving the disinfection effect by pre-treating the air.

[0283] In step 2114, the system uses a PTC heating element 168 to preheat the airflow passing through the housing to ensure optimal conditions for ozone mixing and photocatalytic reaction on the titanium dioxide coating surface 110.

[0284] In step 2116, the PTC heating element 168 and the ultraviolet (UV) lamps 108A / 108B operate synchronously, and the air treatment effect is improved by combining thermal regulation and photo-oxidation processes.

[0285] In step 2118, when the water tank replacement status indicates that it is depleted or the replaceable water filter cartridge 126 is misaligned, the controller 500 generates an alarm. This alarm can be displayed on the display 506, sent to the remote computing device 732, or recorded in the memory 504 for later review.

[0286] refer to Figure 23B illustrates an example embodiment of a method for disinfection using a modular ozone disinfection system 100 with a replaceable water filter cartridge 126, which is interchangeable with other methods of the present invention. This method expands the system's applicability by integrating geolocation, wireless data communication, and dynamic control functions, thereby ensuring a safe, compliant, and responsive disinfection process to changing environmental and operating conditions. The method begins at step 2120 by wirelessly transmitting operational status data via a communication interface 508 integrated with the disinfection system 100. The communication interface 508 is functionally associated with a controller 500, enabling real-time transmission of operational data to a remote data processing resource 702 or a computing device 732.

[0287] In step 2122, the system determines the geographic location of the modular ozone disinfection system 100 via the Global Positioning System (GPS) module 514. The GPS module 514 is associated with the controller 500, enabling the system to track its current location.

[0288] In step 2124, when the GPS module 514 detects that the system is outside a predefined geographical area stored in the controller memory 504, the controller 500 disables the electrochemical ozone generator 516. This ensures that ozone disinfection operations are only performed in authorized or appropriate environments.

[0289] In step 2126, when the GPS module 514 detects that the system has returned to a predefined geographic area, the electrochemical ozone generator 516 is reactivated. This geofencing function ensures the safe and compliant use of the ozone generator.

[0290] In step 2128, the system records timestamped operational data, including ozone generation cycles, water tank status, and other performance metrics. These logs can be used for audit verification, compliance checks, and operational analysis.

[0291] In step 2130, the controller 500 receives a remote overlay command from the remote data processing resource 702 or the computing device 732. This command can be used to remotely start, modify, or pause a preset operating mode, enabling remote control and monitoring by technicians 302 or administrators 304.

[0292] In step 2132, sensor 512 compares the ozone concentration in the output airflow (e.g., ozone flow 414 or purified airflow 408) with a preset safety threshold, and generates a safety signal if the safety limit is exceeded. This automatic safety mechanism ensures that only ozone levels that meet human exposure safety limits are released into the occupied environment.

[0293] The functions of this invention can be implemented by software, firmware, hardware, or a combination thereof.

[0294] For example, one or more aspects of the invention may be incorporated into an article of manufacture (e.g., one or more computer program products) having a computer-usable medium. This medium may, for example, contain computer-readable program code for providing and implementing the functions of the invention. The article of manufacture may be sold as part of a computer system or separately.

[0295] In addition, at least one machine-readable program storage device may be provided, wherein at least one machine-executable program instruction is stored in a tangible manner for performing the various functions of the present invention.

Various variations may be made to these flowcharts or the steps (or operations) described therein without departing from the spirit of the invention. For example, these steps may be performed in different orders, or steps may be added, deleted, or modified. All such variations are considered to be within the scope of the invention.
