These special environments are characterized by limited space and frequent personnel movement, placing stringent requirements on air handling equipment for efficient disinfection, continuous operation, and compact design. Currently, air handling equipment for such scenarios primarily employs single technologies such as ultraviolet disinfection, chemical spraying, or negative ion generation, which generally suffer from functional limitations and usage defects. Furthermore, existing equipment struggles to balance space utilization and treatment effectiveness in its structural layout and disinfection methods, frequently resulting in incomplete disinfection or inconvenient maintenance in practical applications. With increasing public health requirements, developing an air handling device that adapts to the characteristics of small, enclosed spaces, integrates disinfection and deodorization, and is easy to maintain has become a pressing technical challenge for the industry.

The housing 1 is detachably connected, and the first panel and the second panel are provided with a first air inlet 21; the filter assembly 3 is disposed in the storage cavity and is located at the first air inlet 21. The filter assembly 3 includes a pre-filter 31, and the input end of the pre-filter 31 is set towards the first air inlet 21; the disinfection assembly is disposed in the storage cavity and the output end of the disinfection assembly is set towards the first air outlet 11.

[0042] In this embodiment, the base plate is a fundamental support component used to support the entire device and fix it to the wall. Its material is preferably metal or high-strength plastic to ensure structural stability. The first side plate and the second side plate are arranged opposite each other to form a side wall structure for the storage cavity, and the first air outlet 11 on it guides the purified air upwards for discharge. The storage cavity formed by the staggered arrangement of the first and second panels and the side plates is a closed space for accommodating the disinfection components and the control unit 6, ensuring both the integrity of the airflow channel and ease of maintenance. Furthermore, the upper housing 2 is also provided with a fixed connection structure, which can be selected as standard connecting components such as hooks and fasteners, for securely installing the device in specific application scenarios such as elevator cars, corridor walls, or building ceilings. By adding a fixed connection structure, the integrity of the device is maintained, and the applicability of wall-mounted installation is expanded, allowing the disinfection device to be flexibly deployed according to different space requirements.

[0043] Preferably, the pre-filter 31 is designed to be detachable to intercept suspended particles in the air. The active composite particle disinfection group 4 is a module that generates active particles such as hydroxyl radicals through an electrochemical reaction, used to destroy the cell structure of microorganisms; the negative oxygen ion disinfection group 5 is a component that generates negative ions through high-voltage discharge, used to neutralize positively charged particles. Preferably, the control unit 6 integrates an infrared sensing module for automatically adjusting the disinfection intensity according to human activity.

[0044] During implementation, air enters through the first air inlet 21 and sequentially passes through the physical filtration of the pre-filter 31, the chemical disinfection of the active composite particle disinfection group 4, and the electrostatic purification of the negative oxygen ion disinfection group 5, finally forming a circulating airflow through the first air outlet 11. The control unit 6 dynamically optimizes the disinfection and purification function by monitoring the environmental status in real time and coordinating the working modes of the two-stage disinfection components.

[0045] In this embodiment, a storage cavity is formed by the detachable connection of the lower housing 1 and the upper housing 2, enabling the filter assembly 3 and the disinfection assembly to work together. Air enters through the first air inlet 21 on the first panel and the second panel, is filtered by the pre-filter 31, and then undergoes dual treatment by the active composite particle disinfection group 4 and the negative oxygen ion disinfection group 5, finally being discharged through the first air outlet 11 on the first side panel and the second side panel. The control unit 6 adjusts the working mode of the filter assembly 3 and the disinfection assembly according to the environmental conditions, realizing automatic control of air purification and disinfection. The device optimizes the airflow path through the staggered enclosure structure of the housing, allowing the air to circulate fully within the storage cavity. The detachable connection facilitates maintenance and replacement of components such as the pre-filter 31, making it suitable for enclosed spaces requiring continuous air purification.

[0046] In some embodiments, the filter assembly 3 includes a primary filter element groove 32 and a filter element cover 33. The primary filter element groove 32 is disposed on the inner side wall of the upper housing 2, and the size of the primary filter element groove 32 is adapted to the first air inlet 21. A primary filter element 31 is disposed in the primary filter element groove 32. The filter element cover 33 is embedded on the outer side of the first air inlet 21. The filter element cover 33 is provided with a plurality of first ventilation holes 331, and the first air outlet 11 is provided with a plurality of second ventilation holes 111.

[0047] In this embodiment, the primary filter element groove 32 is a receiving structure disposed on the inner side wall of the upper housing 2 and adapted to the size of the first air inlet 21. It is used to fix the primary filter element 31 and ensure that the airflow enters the storage cavity after passing through the primary filter element 31. The filter element outer cover 33 refers to the cover embedded on the outside of the first air inlet 21, and the multiple first ventilation holes 331 on it are used to guide the external air to enter the primary filter element 31 evenly. The primary filter element 31 is the filter medium disposed in the primary filter element groove 32, used to intercept large particulate impurities in the air. The multiple second ventilation holes 111 provided on the first air outlet 11 are used to evenly discharge the treated air from the device.

[0048] During operation, air enters through the first ventilation hole 331 of the filter cover 33, undergoes preliminary filtration by the pre-filter 31, and then enters the storage chamber. It then flows through the active composite particle disinfection group 4 and the negative ion disinfection group 5 for synergistic treatment. The active composite particle disinfection group 4 generates active particles through an electrochemical reaction to destroy the structure of microorganisms, while the negative ion disinfection group 5 releases negative ions to cause suspended particles to agglomerate and settle. Finally, the purified air is discharged through the second ventilation hole 111 of the first air outlet 11, forming a circulating airflow.

[0049] This embodiment ensures the stability and uniformity of air filtration by setting up a pre-filter cartridge slot 32 and a filter cartridge cover 33. The distribution of the first ventilation hole 331 and the second ventilation hole 111 optimizes the airflow path, allowing air to fully contact the disinfection components within the device and improving purification efficiency. The detachable structure of the filter cartridge cover 33 facilitates the maintenance and replacement of the pre-filter cartridge 31, while the adaptable size of the pre-filter cartridge slot 32 ensures the sealing of the filter components. Through the synergistic effect of the two-stage disinfection components combined with intelligent control, this device achieves continuous and efficient purification and disinfection of air in enclosed spaces, making it suitable for environments with high air quality requirements.

[0052] In some embodiments, the active composite particle disinfection group 4 includes: an active composite particle high-pressure pack 41, an active composite particle control module 42, an active composite particle generator 43, and a fan group.

The fan group is electrically connected to the control unit 6. The input end of the fan group is set towards the output end of the primary filter element 31, and the output end of the fan group is set towards the first air outlet 11. The active composite particle generator 43 is disposed between the fan group and the first air outlet 11.

[0053] In this embodiment, the high-voltage transformer 41 for active composite particles is a module that provides high-voltage power to the active composite particle generator 43. Its input end is connected to the active composite particle control module 42, and its output end is connected to the active composite particle generator 43. The active composite particle control module 42 is a circuit unit that coordinates and controls the high-voltage transformer 41 for active composite particles, and it is communicatively connected to the control unit 6 to receive operating commands. The active composite particle generator 43 generates active particles through high-voltage electrolysis and is positioned between the fan unit and the first air outlet 11 to optimize particle diffusion. The fan unit is a mechanical component that drives airflow. Its input end is positioned towards the output end of the primary filter element 31 to introduce filtered air, and its output end is positioned towards the first air outlet 11 to form a directional airflow.

[0054] During implementation, the active composite particle control module 42 coordinates the working status of the fan unit and the active composite particle high-pressure transformer 41 according to the instructions of the control unit 6. When the fan unit is running, it delivers filtered air to the active composite particle generator 43 area. At the same time, the active composite particle high-pressure transformer 41 drives the generator to produce active particles. These particles are discharged from the first air outlet 11 with the airflow to achieve air disinfection. All components are electrically connected to form a closed-loop control system to ensure the efficient and stable operation of the disinfection process.

[0055] This embodiment achieves efficient air disinfection through structural optimization of the active composite particle disinfection unit 4. The coordinated arrangement of the fan unit and the active composite particle generator 43 ensures uniform diffusion of active particles, and the precise control of the active composite particle control module 42 allows the disinfection intensity to be dynamically adjusted according to environmental needs. This not only improves disinfection efficiency but also simplifies the system structure through modular electrical connections, enhancing operational reliability. It is suitable for medical, office, and other places with continuous air disinfection requirements.

[0056] In some embodiments, the active composite particle generator 43 includes: a discharge frame 431, a heat sink 432, a discharge needle 433, a PN junction 434, a water-absorbing ceramic 435, and a high-voltage electrode sheet 436. The discharge frame 431 has a first mounting surface and a second mounting surface, which are arranged opposite to each other, with the second mounting surface perpendicular to the base plate. The heat sink 432 is disposed on the second mounting surface and is perpendicular to the base plate. The discharge needle 433 is disposed on the first mounting surface. The PN junction 434 is disposed on the first mounting surface and is disposed on the discharge frame 431. Between the electric needle 433 and the first mounting surface, the PN junction 434 is electrically connected to the discharge needle 433 and the heat sink 432 respectively; the water-absorbing ceramic 435 is disposed on the side of the discharge needle 433 away from the PN junction 434, and the discharge needle 433 passes through the water-absorbing ceramic 435 and extends outward; the high-voltage electrode plate 436 is disposed on the discharge frame 431, the high-voltage electrode plate 436 is annular, and the radial cross section of the high-voltage electrode plate 436 is arc-shaped, the discharge needle 433 and the high-voltage electrode plate 436 are coaxially disposed, and the high-voltage electrode plate 436 is electrically connected to the active composite particle high-voltage package 41.

[0057] In this embodiment, the discharge frame 431 has a first mounting surface and a second mounting surface arranged opposite to each other, forming a stable discharge space structure. It should be noted that the active composite particle generator 43 is fixed to a screw post on the side of the first air outlet 11 via screw holes on the upper part of the discharge frame 431, and is not directly fixed to the top of the base plate. Only the bottom of the active composite particle generator 43 is placed on the base plate, and the second mounting surface is perpendicular to this base plate; that is, the discharge frame 431 is vertically erected on the base plate. The heat sink 432 is disposed between the second mounting surface and the base plate, and is electrically connected to the active composite particle control board. Similarly, the heat sink 432 is also vertically erected on the base plate. The heat sink 432 is also electrically connected to the PN junction 434 to conduct the heat generated by the PN junction 434 during operation, ensuring stable operation of the device over a long period. The discharge needle 433 is fixed to the first mounting surface, and its tip, serving as the discharge electrode, penetrates the water-absorbing ceramic 435, allowing it to adsorb water molecules from the air. The PN junction 434 is a semiconductor element disposed between the discharge needle 433 and the first mounting surface, and is electrically connected to the discharge needle 433 to form a discharge circuit. The water-absorbing ceramic 435 is a ceramic material with a porous structure, which encapsulates the discharge needle 433 to enhance the adsorption effect of water molecules. The high-voltage electrode sheet 436 is annular with an arc-shaped radial cross-section, and is coaxially arranged with the discharge needle 433 to form a uniform electric field distribution. It is connected to the active composite particle high-voltage package 41 to provide a high-voltage power supply.

[0058] During implementation, the high voltage provided by the high-voltage pack 41 for the active composite particles creates a discharge electric field between the discharge needle 433 and the high-voltage electrode plate 436. Water molecules adsorbed on the discharge needle 433 generate active particles such as hydroxyl radicals under high-voltage electrolysis. The heat sink 432 promptly dissipates the heat generated by the PN junction 434, maintaining discharge stability. The generated active particles are discharged from the air outlet with the airflow, achieving efficient air disinfection. All components work together to ensure the continuous and stable generation of active particles.

[0059] This embodiment achieves highly efficient air disinfection through an optimized structure of the active composite particle generator 43. The coaxial arrangement of the discharge needle 433 and the arc-shaped high-voltage electrode plate 436 forms a uniform electric field, improving discharge efficiency and active particle yield. The porous structure of the water-absorbing ceramic 435 enhances the water molecule adsorption capacity, providing sufficient raw materials for continuous electrolysis. The heat sink 432 ensures the operational stability of the PN junction 434, extending the device's lifespan. This embodiment not only improves disinfection efficiency but also achieves miniaturization and modularization, facilitating maintenance and installation, and is suitable for various locations requiring continuous air disinfection, such as medical facilities and offices. Simultaneously, the optimized discharge structure reduces energy consumption, making the device more energy-efficient and environmentally friendly while maintaining disinfection effectiveness.

[0060] In some embodiments, the fan unit includes a first fan 44 and a second fan 45, wherein the first fan 44 is mounted on a base plate; the second fan 45 is mounted on the base plate, and the first fan 44 and the second fan 45 are arranged at an angle.

[0061] In this embodiment, the fan unit is an aerodynamic assembly composed of a first fan 44 and a second fan 45. Both the first fan 44 and the second fan 45 are fixed to the base plate and arranged at an angle. This angle arrangement can form cross airflow, enhance airflow efficiency, and ensure uniform diffusion of active composite particles.

[0062] This embodiment generates synergistic airflow by arranging the two fans at an angle, which not only improves air circulation efficiency but also ensures the full diffusion of disinfection particles, making the purification effect more uniform and thorough, while reducing the workload of a single fan.

[0063] In some embodiments, the negative ion disinfection group 5 includes: a negative ion high-pressure pack 51 and a negative ion emitter 52. The negative ion high-pressure pack 51 is disposed on the base plate and is electrically connected to the control unit 6. The negative ion emitter 52 is disposed at the first air outlet 11 and is electrically connected to the negative ion high-pressure pack 51.

[0064] In this embodiment, the negative oxygen ion high-voltage transformer 51 is fixed to the base plate and is used to convert the low-voltage electricity provided by the control unit 6 into high-voltage electricity; the negative oxygen ion emitter 52 is set at the first air outlet 11, and its needle-shaped electrode ionizes the air to generate negative oxygen ions under the action of high voltage. This component is electrically connected to the control unit 6 to realize intelligent control of the working mode.

[0065] During implementation, the control unit 6 controls the output voltage of the negative oxygen ion high-voltage transformer 51 to drive the negative oxygen ion emitter 52 to generate a high concentration of negative oxygen ions. These negative ions diffuse from the air outlet into the space with the airflow, combine with positively charged particles to cause them to settle, and neutralize harmful substances in the air, thus achieving air purification.

[0066] This embodiment achieves highly efficient air purification by optimizing the layout and operating mode of the negative ion disinfection group 5. The negative ion emitter 52 is directly installed at the air outlet, ensuring that negative ions quickly diffuse throughout the space with the airflow; the intelligent linkage with the control unit 6 allows the system to automatically adjust the negative ion concentration according to environmental needs. This embodiment not only improves air purification efficiency but also forms a dual guarantee of disinfection and purification through synergy with the active composite particle disinfection group 4, effectively improving indoor air quality. At the same time, the compact layout saves installation space and is suitable for various places requiring continuous air purification, especially small enclosed spaces such as elevators and restrooms.

[0067] In some embodiments, the disinfection device further includes a working indicator light 7, which is disposed on the outside of the top plate and / or the bottom plate, and is electrically connected to the control unit 6.

[0068] In this embodiment, the working status light is connected to the control unit 6. The light is red when the power is on, green when the working status is on, and does not light up when the power is off.

[0069] This embodiment achieves an intuitive and visual display of the device's operating status by setting up a working indicator light 7 that is electrically connected to the control unit 6. A red light illuminates when the power is on to indicate standby mode, a green light illuminates during operation to indicate normal operation, and the light automatically turns off when the power is off. This allows users to quickly grasp the device's operating status, improving the convenience of human-machine interaction and providing timely feedback on device operation. This helps users use and maintain the device properly, while the external placement of the indicator light ensures easy observation.

[0070] In some embodiments, the disinfection device further includes: a power interface 12 and a control switch 13. The power interface 12 is disposed on the lower housing 1 and is disposed on the opposite side of the first air outlet 11. The power interface 12 is electrically connected to the control unit 6. The control switch 13 is disposed adjacent to the power interface 12 and is electrically connected to the control unit 6.

[0071] In this embodiment, the power interface 12 is a power supply connection port located on the back of the lower housing 1, used to connect an external power source to power the device. Its arrangement on the opposite side from the first air outlet 11 avoids interference from wiring with airflow. The control switch 13 is a physical push-button switch, located adjacent to the power interface 12 for easy operation, and the device start / stop function is realized through the control unit 6.

[0072] This embodiment ensures both power supply stability and operational convenience by strategically placing the power interface 12 and control switch 13. Separating the power interface 12 from the first air outlet 11 avoids obstructing airflow with wiring, while the easily accessible switch optimizes the user experience, making device control more intuitive and efficient.

[0073] In some embodiments, the disinfection device further includes an infrared human body sensor 8, which is disposed on the upper housing 2 or the lower housing 1 and is electrically connected to the control unit 6.

[0074] In this embodiment, the infrared human body sensor 8 is electrically connected to the control unit 6 to monitor the surrounding human activity in real time. When a person is detected entering the operating space, the device automatically adjusts its working mode to a high-power disinfection mode to ensure efficient and rapid air disinfection and purification in occupied environments; in unoccupied environments, the device can adjust its working intensity to enter a low-power mode according to a preset program to achieve energy saving.

[0075] Furthermore, the device supports remote monitoring and can be operated and its status viewed remotely via network connection.

[0076] This embodiment achieves intelligent adjustment of the disinfection device's operating mode by incorporating an infrared human body sensor 8 connected to the control unit 6. When the sensor detects human activity, it automatically switches to a high-power disinfection mode to ensure efficient purification in occupied environments; when no one is present, it enters a low-power state, ensuring both disinfection effectiveness and energy consumption. This embodiment not only improves disinfection efficiency and energy saving but also enhances the device's intelligence and ease of operation, making the air purification process more precise and efficient.

[0077] By adopting the above technical solutions, this utility model differs from the prior art and has the following beneficial effects: By providing a wall-mounted air purification and disinfection device, it achieves efficient and intelligent air purification and disinfection functions. The detachable connection between the lower shell 1 and the upper shell 2 forms a storage cavity, enabling the filter assembly 3 and the disinfection assembly to work together. The pre-filter 31, the active composite particle disinfection group 4, and the negative oxygen ion disinfection group 5 constitute a three-stage purification system, ensuring that the air undergoes comprehensive treatment through physical filtration, chemical disinfection, and electrostatic purification. The control unit 6 intelligently adjusts the working mode of the disinfection assembly according to the environmental conditions, and works with the infrared human body sensor 8 to achieve automatic power switching between occupied and unoccupied environments, ensuring both disinfection effectiveness and energy saving. The fan unit adopts a dual-fan arrangement (i.e., the first fan 44 and the second fan 45) at an angle to optimize airflow circulation efficiency. The discharge needle 433 of the active composite particle generator 43 is coaxially set with the arc-shaped high-voltage electrode plate 436, and works with the heat sink 432 and the water-absorbing ceramic 435 to ensure the stable and efficient generation of active particles. The layout of the indicator light 7, power interface 12, and control switch 13 improves operational convenience, while the remote monitoring function enhances the intelligence of the equipment. Through modular design and a collaborative working mechanism, the above technical solutions achieve high efficiency, stability, and convenience in air purification and disinfection, making them suitable for enclosed spaces with high air quality requirements, and particularly suitable for small enclosed spaces such as elevators and restrooms.

[0078] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this utility model, this should not limit the scope of patent protection of this utility model. Any technical solutions resulting from equivalent structural or procedural substitutions or modifications made based on the essential concept of this utility model and utilizing the content described in the text and drawings of this utility model, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this utility model.
