[0002] In indoor environmental control, air conditioning equipment such as wall-mounted air conditioners can regulate indoor air temperature and humidity. Through cooling, heating, and dehumidification, they create a suitable temperature and humidity environment for users, meeting their daily comfort needs. However, with increasing awareness of public health and safety, indoor air disinfection has become a crucial aspect of protecting people's health. For example, in hospital wards, kindergartens, and nursing homes, effectively killing bacteria, viruses, and other microorganisms in the air to reduce the risk of infection is particularly important.

[0003] In related technologies, air conditioning equipment does not have air disinfection functions during the air conditioning process, making it difficult to meet air disinfection needs. Furthermore, space limitations make it difficult to install disinfection devices inside. This forces users to purchase separate, independently operating air disinfection equipment to achieve comprehensive indoor air purification and disinfection, increasing their financial burden. Additionally, using a separate disinfection unit and a wall-mounted air conditioner simultaneously can cause air turbulence, reducing the efficiency and effectiveness of indoor disinfection.

Detailed Implementation

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] like Figures 1 to 7 As shown, the present invention provides a corona disinfection device, which includes a housing 10, a corona generating component 20, and a control component 30. The housing 10 has a receiving cavity 11, which has an air inlet 111 and an air outlet 112. The corona generating component 20 is disposed within the receiving cavity 11 and includes a substrate 22 and a discharge needle 23. The substrate 22 has a corona cavity 221, which is connected to the air inlet 111 and the air outlet 112. The discharge needle 23 has a discharge end 231. A power supply module 21 is correspondingly connected to the inner wall of the discharge needle 23 and the corona cavity 221. The discharge end 231 is disposed within the corona cavity 221 to form a corona field. A filter 12 is disposed between the substrate 22 and the air inlet 111. The control component 30 is electrically connected to the corona generation component 20. The control component 30 includes a pneumatic starter / stopper 31, which is used to monitor the flow state of the gas in the corona chamber 221. The power supply module 21 is used to supply power to the corona generation component 20 when the pneumatic starter / stopper 31 detects the flow of gas in the corona chamber 221.

[0031] Specifically, the outer shell 10 is the supporting structure of the entire device. Air can enter the accommodating cavity 11 through the air inlet 111, and the air outlet 112 is the outlet for the air after it has been disinfected by the corona field formed in the corona cavity 221 by the corona generating component 20. This allows the air to form a continuous flow path in the accommodating cavity 11, thereby achieving effective disinfection of the air.

[0032] The power supply module 21 provides a stable and high-voltage power supply to the corona generation component 20. It supplies power to the inner wall of the corona cavity 221 on the substrate 22 and the discharge needle 23, thereby creating an electric field between the discharge end 231 of the discharge needle 23 and the inner wall of the corona cavity 221. Under the action of this electric field, molecules in the air are ionized to generate a large number of positive ions and electrons, forming a corona field within the corona cavity 221. This corona field effectively kills bacteria, viruses, and microorganisms in the air, achieving the purpose of disinfection.

[0033] The pneumatic starter / stopper 31 can monitor the airflow in the corona chamber 221 in real time. Of course, since the corona chamber 221 is located in the accommodating cavity 11, air enters the accommodating cavity 11 through the air inlet 111, which is also the corona chamber 221. Therefore, in some embodiments of this application, the pneumatic starter / stopper 31 can also monitor the airflow in the accommodating cavity 11.

[0034] During operation, when the pneumatic start-stop device 31 detects gas flow within the accommodating cavity 11 or the corona chamber 221, it sends a signal (power supply signal) to the power supply module 21. Upon receiving the power supply signal, the power supply module 21 supplies power to the discharge needle 23 and the inner wall of the corona chamber 221, thereby initiating air disinfection. When the air within the accommodating cavity 11 or the corona chamber 221 is still (or the air has a flow velocity lower than a preset speed threshold), the pneumatic start-stop device 31 sends another signal (power off signal) to the power supply module 21. At this time, the power supply module 21 stops supplying power, causing the corona generating component 20 to stop working. This forms an automatic start-stop control system centered on the pneumatic start-stop device 31, which not only achieves automated operation of the device but also improves energy utilization efficiency and avoids unnecessary energy waste.

[0035] As can be seen from the above, the corona disinfection device achieves automatic start and stop based on the fan-driven start-stop device 31, which can be effectively adapted to various types of air conditioning equipment. It does not need to be connected to the controller of the air conditioning equipment, and can be used immediately after installation, greatly improving the convenience of use.

[0036] Furthermore, a filter 12 is provided between the air inlet 111 of the outer casing 10 and the substrate 22. This filter effectively filters large particles of dust, hair, small insects, and other impurities from the air, preventing them from entering the corona chamber 221. This ensures cleaner air entering the corona chamber 221, facilitating the effective sterilization of airborne microorganisms by the corona field. Additionally, the filter 12, positioned between the air inlet 111 and the substrate 22, effectively isolates impurities outside the device, eliminating the need for a dust collection box inside. This simplifies the overall structure and reduces the overall thickness. This allows the corona disinfection device provided in this application to be more flexible and adaptable to various application scenarios, especially in confined spaces and locations with thickness restrictions, enabling easy installation and use.

[0037] In summary, the corona disinfection device provided in this application, through the substrate 22, discharge needle 23, power supply module 21, and fan start / stop device 31, forms a highly efficient, energy-saving, and more practical air disinfection solution. Users can install it onto existing air conditioning units as needed, effectively improving indoor air quality without requiring modifications to existing units, thus significantly reducing operating costs. Furthermore, the filter 12 positioned between the air inlet 111 and the substrate 22 helps simplify the device's structure and reduce its overall thickness.

[0038] In some embodiments, the pneumatic start-stop device 31 includes a first temperature monitoring element, a second temperature monitoring element, and a processor. The first temperature monitoring element is used to monitor the temperature inside the corona chamber 221, the second temperature monitoring element is used to monitor the temperature of the environment where the corona disinfection device is located, and the processor is used to determine the airflow state inside the accommodating cavity 11 based on the temperature data collected by the first and second temperature monitoring elements.

[0039] In this embodiment, a first temperature monitoring element is disposed within the accommodating cavity 11, which is connected to the corona discharge cavity 221. The first temperature monitoring element monitors the airflow within the accommodating cavity 11, which in turn monitors the airflow within the corona discharge cavity 221. In other words, during use, when air flows through the accommodating cavity 11, the flowing air changes the temperature within the accommodating cavity 11, and the first monitoring element can monitor the temperature within the accommodating cavity 11 in real time. The second temperature monitoring element can monitor the ambient temperature of the environment where the corona disinfection device is located in real time. Both the first and second temperature monitoring elements send the collected temperature data to the processor.

[0040] When the processor detects that the difference between the temperature inside the accommodating cavity 11 collected by the first temperature monitoring element and the ambient temperature collected by the second temperature monitoring element is greater than or equal to a preset threshold, the processor will determine that there is air flow inside the accommodating cavity 11. At this time, the processor will send a signal to the power supply module 21 or make the circuit between the power supply module 21 and the corona generation component 20 conduct, so that the power supply module 21 provides current to the corona generation component 20 to start the corona generation component 20.

[0041] Furthermore, the processor can be one or a combination of multiple central processing unit (CPU), digital signal processor, application-specific integrated circuit, field-programmable gate array or other programmable logic device, discrete gate or transistor logic device, or discrete hardware component.

[0042] Furthermore, it should be noted that in some other embodiments of this application, the wind-driven start-stop device 31 may also include a propeller-type sensor, which may be disposed within the accommodating cavity 11. The propeller-type sensor can measure the wind speed by measuring the rotational speed of the propeller, thereby detecting whether there is airflow within the accommodating cavity 11.

[0043] In some embodiments, the inner wall of the corona cavity 221 and the discharge needle 23 can be connected to the same power supply module 21, or they can be connected to different power supply modules 21, as long as there is a potential difference between the inner wall of the corona cavity 221 and the discharge end 231 of the discharge needle 23. For example, the inner wall of the corona cavity 221 and the discharge needle 23 are connected to the same power supply module 21. That is, the power supply module 21 has a positive electrode and a negative electrode, one of which is connected to the inner wall of the corona cavity 221, and the other of which is connected to the discharge needle 23, so as to form a corona field in the corona cavity 221. In this embodiment, the negative electrode of the power supply module 21 is connected to the inner wall of the corona cavity 221, and the positive electrode of the power supply module 21 is connected to the discharge needle 23.

[0044] Furthermore, the power supply module 21 can be connected to an external power source via wires, or to components such as batteries via wires. Optionally, the battery can be integrated into the housing 10 or used as an external device, thus making it suitable for locations without mains power or with unstable mains power, such as outdoor camping or emergency rescue sites.

[0045] In some embodiments, the substrate 22 may be a metal plate, and the substrate 22 may be electrically connected to the power supply module 21, so that the current output by the power supply module 21 flows through the substrate 22 to the inner wall of the corona cavity 221, so that the discharge needle 23 achieves a discharge effect in the corona cavity 221. Of course, in some other embodiments of this application, the substrate 22 may also have a metal layer only on the inner wall of the corona cavity 221, and the power supply module 21 is connected through the metal layer to realize the current transmission.

[0046] In some embodiments, the corona cavity 221 is configured as circular, elliptical, or polygonal, such as quadrilateral, hexagonal, etc.

[0047] In this embodiment, the corona cavity 221 is set to be circular, the output voltage of the power supply module 21 is V, and the radius of the corona cavity 221 is set to R.

[0048] During the discharge process of the corona generating component 20, the magnitude of the output voltage V directly affects the intensity of the electric field, determining the corona generation capability and the air disinfection efficiency. The size (radius R) of the corona cavity 221 is related to the airflow characteristics and the distribution range of the electric field.

[0049] It's important to note that if the output voltage is too low, a sufficiently strong electric field cannot be generated, resulting in insufficient corona discharge and a significant decrease in disinfection effectiveness, failing to meet medical-grade requirements. Conversely, while a high output voltage can enhance the electric field strength, it also triggers a series of problems. Excessively high voltage can cause overly intense corona discharge, producing large amounts of ozone. Ozone is a highly oxidizing gas; although it has some bactericidal effect, its concentration exceeding the US UL2998 standard can harm human health, causing symptoms such as respiratory irritation and headaches, making it unsuitable for use in occupied environments. Only by achieving the optimal balance between generating a sufficiently strong electric field for medical-grade disinfection and controlling ozone production within safe limits to meet the US UL2998 zero-ozone standard can the product be used in occupied environments, greatly increasing its applicability and all-weather usability.

[0050] Furthermore, the radius of the corona cavity 221 can be set to 0.75 to 1.5 cm, for example, 0.75 cm, 1 cm, 1.1 cm, 1.5 cm, etc. The output voltage of the power supply module 21 is set to 4800 to 6300 volts, for example, 4800 volts, 5000 volts, or 8000 volts, etc. The output current of the power supply module 21 is 10 microamps to 1000 microamps, for example, 10 microamps, 200 microamps, 500 microamps, or 1000 microamps, etc.

[0051] The inventors discovered that the radius of the corona cavity 221 can be set to 1.1 cm. This ensures that the disinfection area formed by the electric field around the hole is neither too narrow, preventing some air from being effectively disinfected, nor too wide, causing the electric field strength to be dispersed. This guarantees the uniformity and efficiency of the disinfection effect. The output voltage of the power supply module 21 is set to 4800 to 6300 volts. Under the premise of ensuring safety, this maximizes the potential of corona discharge and achieves efficient air disinfection.

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the outer shell 10 includes a first shell 13 and a second shell 15 disposed opposite to each other, and a plurality of discharge needles 23 are provided, which are arranged in an array on the first shell 13 or the second shell 15, and the corona cavity 221 is disposed corresponding to the discharge needles 23.

[0053] Specifically, the outer casing 10 adopts a split design, that is, the second casing 15 and the first casing 13 are arranged opposite to each other, and the second casing 15 and the first casing 13 are joined together to form a receiving cavity 11, which greatly simplifies the production process and effectively improves production efficiency and product consistency. In terms of maintenance, when a fault occurs or cleaning and maintenance are required, the corona generating component 20 can be easily operated by simply separating the second casing 15 and the first casing 13, which greatly reduces maintenance costs and time.

[0054] The discharge needles 23 are arranged in an array on the second housing 15 or the first housing 13. From the perspective of discharge efficiency, the array arrangement allows the electric fields of the discharge needles 23 to cooperate and interact synergistically, forming an orderly and powerful electric field environment, thereby increasing the frequency and intensity of the discharge and providing sufficient energy for the air disinfection process. From a space utilization perspective, this arrangement allows for the placement of as many discharge needles 23 as possible within a limited space, increasing the discharge density per unit volume and enhancing the overall disinfection capability.

[0055] Furthermore, the corona cavity 221 on the substrate 22 is correspondingly arranged with the discharge needle 23, which can provide a relatively independent working environment for the discharge needle 23, avoid interference from external factors, and help to better form a uniform and stable corona field.

[0056] Furthermore, in this embodiment, the accommodating cavity 11 includes a ventilation cavity and a control cavity. The filter 12, substrate 22, and discharge needle 23 are all disposed in the ventilation cavity, while the control component 30 and power supply module 21 are disposed in the control cavity, achieving a separate design and avoiding interference with the operation of the control components (control component 30 and power supply module 21) during the disassembly of components such as the filter 12. Correspondingly, in this embodiment, the first temperature monitoring element monitors the airflow within the ventilation cavity.

[0057] Furthermore, the first housing 13 also includes a conductive strip 131, which is electrically connected to the power supply module 21. The conductive strip 131 connects adjacent discharge needles 23. From an electrical principle perspective, the conductive strip 131 acts as a bridge between adjacent discharge needles 23, distributing the electrical energy supplied by the power supply module 21 evenly to each discharge needle 23. The conductive strip 131 connects adjacent discharge needles 23, forming an interconnected and mutually supportive power supply network. Even if a single discharge needle 23 malfunctions, it will not affect the operation of other components.

[0058] Furthermore, such as Figure 5 and Figure 7 As shown, the conductive strip 131 has multiple fixing holes 1311, and the discharge needle 23 has a fixing end 232, which is inserted into the fixing hole 1311. The fixing end 232 of the discharge needle 23 is a columnar segment, and the discharge end 231 is a needle-like tip structure; the columnar segment is inserted into the fixing hole 1311. In this embodiment, the conductive strip 131 extends along the length of the outer shell 10, and the multiple fixing holes 1311 are equally spaced on the conductive strip 131. Multiple conductive strips 131 are provided, and the multiple conductive strips 131 are arranged at intervals along the width of the outer shell 10, thereby forming a uniformly distributed corona field within the accommodating cavity 11.

[0059] Alternatively, the discharge needle 23 can be fixed to the conductive strip 131 by means of riveting, welding or threaded structure.

[0060] like Figure 4 , Figure 5 and Figure 7 As shown, in this embodiment, the outer casing 10 also includes a voltage-conducting strip 132. The two ends of the voltage-conducting strip 132 are connected to two adjacent conductive strips 131. That is, the voltage-conducting strip 132 extends along the width direction of the outer casing 10. The voltage-conducting strip 132 can be connected to the power supply module 21 via a wire. In other words, the current output by the power supply module 21 can be transmitted to the discharge needle 23 through the voltage-conducting strip 132 and the conductive strip 131, achieving stable power supply.

[0061] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the discharge needle 23 is disposed on the first housing 13, and the substrate 22 is detachably mounted on the second housing 15. That is, the discharge needle 23 and the substrate 22 are respectively located on the second housing 15 and the first housing 13, which not only facilitates the assembly and disassembly of the entire device, but also facilitates the quick location of the problem and repair when a fault occurs.

[0062] Furthermore, the first housing 13 is provided with multiple mounting holes 133, through which the discharge needles 23 pass. That is, each discharge needle 23 is fixed within the mounting hole 133 to ensure uniform distance between adjacent discharge needles 23, preventing the discharge needles 23 from shaking or loosening during operation of the air conditioning device. Simultaneously, the size of the mounting hole 133 matches the diameter of the discharge needle 23, ensuring smooth insertion of the discharge needle 23 while providing sufficient friction to prevent it from falling off.

[0063] Optionally, the mounting hole 133 is configured as a tapered structure, that is, the cross-sectional area of ​​the mounting hole 133 in the axial direction of the discharge needle 23 gradually decreases from the fixed end 232 of the discharge needle 23 toward the discharge end 231 of the discharge needle 23, so as to avoid the discharge needle 23 from shaking.

[0064] Furthermore, the first housing 13 is provided with a plurality of mounting slots 134, the conductive strip 131 is installed in the mounting slots 134, and mounting holes 133 are spaced apart in the mounting slots 134 along the length of the mounting slots 134. The mounting slots 134 are elongated and their shape and size match the external dimensions of the conductive strip 131 to ensure that the conductive strip 131 can be securely installed in the mounting slots 134.

[0065] like Figure 4 , Figure 5 As shown, in this embodiment, the first housing 13 includes a lower housing 135 and a base plate 136. The lower housing 135 includes a frame 1351 and multiple connecting strips 1352. The multiple connecting strips 1352 are staggered inside the frame 1351 to form an air outlet 112 for air to flow out. Mounting holes 133 are provided in the lower housing 135. The connecting strips 1352 can be divided into horizontal strips 1353 and vertical strips 1354. Mounting grooves 134 and mounting holes 133 are provided on the horizontal strips 1353. A through groove 1356 is provided on the frame 1351, connecting two adjacent mounting grooves 134. The conductive strips 132 are detachably installed into the through groove 1356.

[0066] Furthermore, the lower shell 135 is provided with a first annular groove 1355, and the bottom plate 136 has a first plate 1361 and a second protruding edge 1522. The second protruding edge 1522 extends from the outer periphery of the first plate 1361 toward the plane perpendicular to the first plate 1361. The size of the first annular groove 1355 is adapted to the size of the second protruding edge 1522 so that the bottom plate 136 and the lower shell 135 are engaged.

[0067] like Figure 3 and Figure 4 As shown, in some embodiments, the housing 10 further includes an air guide strip 16, which is located at the air inlet 111. The air guide strip 16 can divert and guide the incoming air, allowing the air to enter the device in a more uniform and stable manner, thereby improving the contact efficiency between the air and the disinfection components and enhancing the disinfection effect. At the same time, the air guide strip 16 also serves as a protective strip to prevent the user from touching the discharge needle 23, ensuring safe use.

[0068] Furthermore, the air inlet 111 has multiple air holes 1111, and multiple air guide strips 16 are provided. The air guide strips 16 are arranged radially in relation to the air holes 1111, such as in a windmill shape or a cross shape, so as to effectively separate and guide the air.

[0069] like Figure 4 , Figure 5 As shown, in some embodiments, the first housing 13 and the second housing 15 are arranged opposite to each other along the thickness direction of the outer shell 10. For ease of description, the second housing 15 is located above the first housing 13, the air outlet 112 is provided on the first housing 13, and the air inlet 111 is provided on the second housing 15.

[0070] The second housing 15 also includes a connected upper housing 151 and a cover plate 152, with the cover plate 152 located on the side of the upper housing 151 facing away from the first housing 13. The air vents 1111 include a first air vent 1111 and a second air vent 1111. The cover plate 152 has the first air vent 1111, and the upper housing 151 has the second air vent 1111. The air guide strips 16 are arranged in a windmill shape within the first air vent 1111. That is, the air guide strips 16 are centered on the center of the first air vent 1111, and adjacent air guide strips 16 form a certain angle, with the overall shape resembling the blades of a windmill.

[0071] In this embodiment, the upper shell 151 includes a receiving cavity 1511, a spacer 1512, and a second annular groove 1513. The substrate 22 is mounted inside the receiving cavity 1511. The spacer 1512 is located at the edge of the receiving cavity 1511, and the second annular groove 1513 is located on the side of the spacer 1512 away from the receiving cavity 1511. A second vent 1111 is located at the bottom of the receiving cavity 1511. The spacer 1512 is a protrusion extending from the bottom of the receiving cavity 1511 along the thickness direction of the outer shell 10 in a direction away from the first shell 13. The second annular groove 1513 is annular. The receiving cavity 1511 has an opening to facilitate the mounting of the substrate 22.

[0072] The cover plate 152 includes a second plate 1521 and a second protruding edge 1522. The first protruding edge 1362 extends from the outer periphery of the second plate 1521 toward a direction perpendicular to the plane where the second plate 1521 is located. The second protruding edge 1522 is detachably fastened into the second annular groove 1513. The second plate 1521, the bottom wall of the receiving cavity 1511, and the second electrode plate are arranged in parallel.

[0073] Furthermore, one of the sidewalls of the second protruding edge 1522 and the second annular groove 1513 is provided with a groove 1523, and the other of the sidewalls of the second protruding edge 1522 and the second annular groove 1513 is provided with a protrusion 1524, the size of which is adapted to the groove 1523. When the protrusion 1524 is engaged with the groove 1523, the cover plate 152 is fixed to the upper cover. In this embodiment, the second protruding edge 1522 is provided with a protrusion 1524, and the sidewall of the second annular groove 1513 is provided with a groove 1523.

[0074] In addition, in some other embodiments of this application, the cover plate 152 and the upper shell 151 can also be fixed by means of bolt connection, adhesive bonding or screw connection. Furthermore, the connection between the bottom plate 136 and the lower shell 135 can also adopt the above-mentioned connection methods, which will not be described in detail here.

[0075] In some embodiments, the thickness of the outer casing 10 is less than or equal to 3.5 cm, such as 2 cm, 2.4 cm, 3 cm, or 3.5 cm. It should be noted that the thickness of the outer casing 10 is not arbitrarily set, but rather the optimal result obtained through extensive experimentation. Taking a wall-mounted air conditioner as an example, during installation, the top of the indoor unit is usually about 8 cm from the ceiling. The outer casing 10 of the corona disinfection device provided in this application is less than or equal to 3.5 cm, which can accommodate the installation space of most wall-mounted air conditioner indoor units without obstructing airflow. Users can confidently install this disinfection device on existing wall-mounted air conditioners without worrying about performance degradation due to device thickness. This truly achieves a reliable disinfection guarantee for indoor air without affecting air conditioner use, creating a healthier and more comfortable indoor environment for users. It balances aesthetics and practicality, allowing the product to be easily installed on most existing wall-mounted air conditioners.

[0076] In some embodiments, the housing 10 is made of insulating material, which can effectively isolate the internally charged corona generating component 20 from the external environment, greatly reducing the risk of electric shock.

[0077] In some embodiments, the filter 12 is sandwiched between the upper housing 151 and the cover plate 152. The filter 12 is made of at least one of nylon, plastic, and fiber, thereby meeting the requirements for filtering impurities in the air and providing a relatively stable working environment for corona discharge while ensuring smooth airflow. In this embodiment, the filter 12 is made of nylon material.

[0078] In some embodiments, the control component 30 further includes a communication module, which can be a wireless communication unit or a wired communication unit. The wireless communication unit may include Wi-Fi (802.11 series), Bluetooth, cellular networks (4G LTE, 5G NR), LoRa, NB-IoT, ZigBee, infrared modules, etc. The wired communication unit may include an RS-485 (Recommended Standard 485) communication unit. RS-485 is a serial communication interface standard and a commonly used communication protocol in industrial control environments. An RS-485 communication unit is a device that conforms to the RS-485 communication protocol. Of course, in some embodiments, the communication module may also be a wired communication component.

[0079] like Figure 5 and Figure 7 As shown, in some embodiments, the control component 30 further includes a working indicator light 32 and a maintenance indicator light 33. The working indicator light 32 is used to indicate the working status of the corona disinfection device using different colors, for example, green indicates normal operation and red indicates equipment failure. The maintenance indicator light 33 illuminates when the processor detects that the voltage drop between the discharge needle 23 and the corona cavity 221 exceeds a preset threshold, indicating that the corona disinfection device needs maintenance. Considering factors such as different usage environments and equipment aging, the preset threshold can be set to different values ​​such as 500 volts or 1000 volts. When the processor detects that the voltage drop between the discharge needle 23 and the corona cavity 221 exceeds the preset threshold, the maintenance indicator light 33 will illuminate in yellow to prompt the user to perform maintenance.

[0080] In this embodiment, the working indicator light 32 and the maintenance indicator light 33 can be set separately, so that during the maintenance cycle of the corona disinfection device, the user can quickly distinguish whether the equipment is in normal working condition, has a fault and needs repair, or needs regular maintenance by observing different indicator lights, thus avoiding information confusion and misunderstanding.

[0081] Furthermore, it should be noted that the size specifications of the corona disinfection device provided in this application can be set as needed, that is, the corresponding size specifications can be set according to the size of the air conditioning device. For example, the corona disinfection device can be set with 3 size specifications to adapt to the needs of 1P air conditioner, 1.5-2.5P air conditioner, and 3P air conditioner.

[0082] Based on the same inventive concept, the present invention also provides an air conditioning device, which includes an air conditioning unit and the corona disinfection device provided in any of the foregoing embodiments. The air conditioning unit can be a wall-mounted air conditioner, a cabinet air conditioner, or an air humidifier, etc.

[0083] In some embodiments, the air conditioning device has an airflow channel, and the corona disinfection device has a working position. When the corona disinfection device is in the working position, it disinfects the air flowing through the airflow channel. That is, the corona disinfection device can have a working position and a non-working position. When the corona disinfection device is in the non-working position, it is not located on the airflow channel. During use, the corona disinfection device can be moved from the non-working position to the working position as needed to disinfect the air within the airflow channel.

[0084] In some embodiments, the air conditioning unit has an air inlet and an air outlet, and the corona disinfection device is located at either the air inlet or the air outlet. That is, the corona disinfection device can be installed at either the air inlet or the air outlet of the air conditioning unit, depending on the needs or space requirements, to achieve effective air disinfection.

[0085] Furthermore, the corona disinfection device is located at the air inlet, and the coverage area of ​​the corona cavity 221 on the substrate 22 is greater than or equal to the air inlet area.

[0086] Specifically, the outer casing 10 of the corona disinfection device can be placed at the air inlet, enabling a pre-disinfection mode. This ensures that the air entering the indoor unit is purified at the initial stage, effectively preventing the growth and spread of harmful microorganisms inside the air conditioning system, thereby greatly improving the overall indoor air quality. Furthermore, the air outlet 112 of the corona disinfection device is positioned flush with the air inlet, ensuring that disinfected air can directly enter the air inlet, reducing the risk of secondary pollution during air transmission.

[0087] The corona cavity 221 on the substrate 22 has a larger coverage area than the air inlet 111, ensuring that all air entering the air inlet 111 can pass through the corona cavity 221 and the corona discharge area. In this way, active particles can be evenly distributed in the air, comprehensively and thoroughly killing microorganisms in the air, thus improving the uniformity and effectiveness of disinfection.

[0088] Furthermore, it should be noted that the air conditioning device provided in this application embodiment has the same implementation principle and technical effect as the aforementioned corona disinfection device embodiment.
