BRIEF DESCRIPTION OF DRAWINGS

[0017] Figure 1 is a system schematic diagram of an embodiment of the air purification device of the present application.

[0018] Figure 2 is a system schematic diagram of another embodiment of the air purification device of the present application. DETAILED DESCRIPTION

[0019] The present application will be described in detail below with reference to exemplary embodiments illustrated in the accompanying drawings. It should be understood, however, that the present application can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be complete and fully convey the concept of the present application to those skilled in the art.

[0020] Referring to Figure 1 which shows one embodiment of an air purification device according to the present application. The air purification device 100 comprises a main body portion having a first mounting space, a second mounting space and a third mounting space for mounting a positive / negative ion module 110, a plasma module 120 and a power supply module 130 respectively. The positive / negative ion module 110 is configured to generate positive and / or negative ions under control, the plasma module 120 is configured to generate plasma under control, and the power supply module 130 is configured to supply power to the positive / negative ion module 110 and the plasma module 120. The air purification device 100 optionally further comprises a controller 140 for controlling the output voltage and on / off of the power supply module 130 to the positive / negative ion module 110 and / or the plasma module 120, thereby to control the magnitude of the output ions of the positive / negative ion module 110 and the plasma module 120.

[0021] With such an arrangement, the air purification device 100 provides better applicability, cost effectiveness and maintenance convenience for the positive / negative ion module 110 and the plasma module 120 by providing mounting spaces for them in the main body portion. Furthermore, since the positive / negative ion module 110 and the plasma module 120 have close output voltage applicability ranges, it is possible for them to share the power supply module 130. This can save part of the hardware cost compared to conventional two sets of ionization purification devices. In addition, in some embodiments with the built-in controller 140, the output voltage of the power supply module 130 to the positive / negative ion module 110 and / or the plasma module 120 can be controlled according to the actual requirements of the application scenario via the coordinated control of the controller, and the working state of the two modules can be turned on / off or adjusted, thereby to achieve adaptive control according to the air treatment requirements, to balance the air purification effect and the generation of by-products such as ozone, to maximize the benefits and minimize the drawbacks.

[0022] In addition, with regard to the foregoing embodiments, it is necessary to mention that the positive / negative ion module 110 and the plasma module 120 applied therein can adopt existing mature positive / negative ion generators and plasma generators.

[0023] For example, the positive / negative ion generator can generate high voltage between the positive electrode generating end 111 and the negative electrode generating end 112 with small power, so as to ionize the air to generate positive / negative ions, so that the two release huge energy in the moment of positive and negative charge neutralization in the air, thereby causing the change of the surrounding bacterial structure and the transfer of energy, resulting in the death of bacteria and achieving the sterilization effect. It can also achieve the effect of efficiently decomposing formaldehyde, benzene series, ammonia and other TVOC and other gaseous organic volatile substances, thereby eliminating odors. In addition, the dust in the air will produce coagulation phenomenon after encountering ions with polarity, increasing the mass of particulate matter and accelerating sedimentation. Charged particles will adhere to the grounding electrode when encountering a zero potential ground surface or other fields during air movement, thereby converting dust into falling dust and reducing inhalable particulate matter in the air.

[0024] Among them, since the state with more negative ions is more conducive to dust removal, odor removal or even human health (such as helping to relieve asthma), and the balanced state of positive / negative ions is more conducive to sterilization and disinfection, the controller can be correspondingly configured so that in the purification mode, the controller controls the positive / negative ion module 110 to generate only negative ions, or controls the positive / negative ion module 110 to generate more negative ions than positive ions. In the disinfection mode, the controller controls the positive / negative ion module 110 to generate a number of negative ions close to the number of positive ions.

[0025] For another example, the plasma generator can generate plasma by creating a strong electric field between the electrode generating end 121 and the ground end 122, thereby achieving outstanding sterilization effect. In this process, there may also be byproducts such as ozone.

[0026] The following will be introduced by exemplary illustration to introduce further modifications of the air purification device in order to further improve its system energy efficiency, reliability or other aspects of improvement.

[0027] For example, in order to better coordinate the working state of the positive / negative ion module and the plasma module in different application scenarios, the controller can also provide multiple air purification gears. Among them, each air purification gear corresponds to a different output voltage of the power supply module 130, so that the positive / negative ion module 110 generates different levels of positive / negative ions and the plasma module 120 generates different levels of plasma. At this time, the output voltage of the power supply module 130 can be controlled by the controller to regulate the purification capacity of the positive / negative ion module 110 and the plasma module 120, and better balance the purification effect and the generation of byproducts.

[0028] More specifically, the power supply module 130 has a first low output voltage and a first high output voltage for the positive / negative ion module 110, so that the positive / negative ion module 110 correspondingly generates low-level positive / negative ions and high-level positive / negative ions; and the power supply module 130 has a second low output voltage and a second high output voltage for the plasma module 120, so that the plasma module 120 correspondingly generates low-level plasma and high-level plasma. At this time, the setting of the power supply module 130 ensures that these air ionization modules can at least be divided into two grades, which provides a hardware basis for realizing the regulation of the purification capacity.

[0029] As an implementation form of an air purification gear, the air purification gear can include a first-level air purification gear and a second-level air purification gear. The first-level air purification gear corresponds to a relatively low air purification demand. At this time, the controller controls the power supply module 130 to supply power to the positive / negative ion module 110, so that the positive / negative ion module 110 generates positive / negative ions, which on the one hand brings a certain degree of air purification effect, and on the other hand does not exist other by-products. The second-level air purification gear corresponds to a relatively high air purification demand. At this time, the positive / negative ions generated by the positive / negative ion module 110 are usually difficult to meet the air purification effect of the application scenario, so the controller controls the power supply module 130 to supply power to the positive / negative ion module 110 and the plasma module 120 respectively, so that the positive / negative ion module 110 generates positive / negative ions, and the plasma module 120 generates plasma. The plasma generated by the plasma module 120 has a very strong air purification effect, but correspondingly also produces by-products such as ozone. Therefore, instead of separately turning on the plasma module 120, the two are turned on at the same time. This aims to reduce the workload of the plasma module 120 through the work of the positive / negative ion module, and accordingly reduce the by-products such as ozone generated by it.

[0030] More specifically, the aforementioned air purification gear can be further subdivided. As an embodiment of a subdivided gear, the first-level air purification gear includes a first low gear and a first high gear. In the first low gear, the controller controls the power supply module 130 to supply power to the positive / negative ion module 110 at a first low output voltage, so that the positive / negative ion module 110 generates low-level positive / negative ions. In the first high gear, the controller controls the power supply module 130 to supply power to the positive / negative ion module 110 at a first high output voltage, so that the positive / negative ion module 110 generates high-level positive / negative ions. Although the positive / negative ion module at any power does not generate by-products, this subdivided gear form can allow it to provide air purification effect as needed, thereby improving efficiency and reducing unnecessary energy consumption.

[0031] The second air purification gear further comprises a second low gear, a second middle gear and a second high gear. In the second low gear, the controller controls the power supply module 130 to supply the positive / negative ion module 110 with a first low output voltage, so that the positive / negative ion module 110 generates a low level of positive / negative ions; and the controller controls the power supply module 130 to supply the plasma module 120 with a second low output voltage, so that the plasma module 120 generates a low level of plasma. In the second middle gear, the controller controls the power supply module 130 to supply the positive / negative ion module 110 with a first high output voltage, so that the positive / negative ion module 110 generates a high level of positive / negative ions; and the controller controls the power supply module 130 to supply the plasma module 120 with a second low output voltage, so that the plasma module 120 generates a low level of plasma. In the second high gear, the controller controls the power supply module 130 to supply the positive / negative ion module 110 with a first high output voltage, so that the positive / negative ion module 110 generates a high level of positive / negative ions; and the controller controls the power supply module 130 to supply the plasma module 120 with a second high output voltage, so that the plasma module 120 generates a high level of plasma. The subdivision of such air purification gears shows the following tendency, i.e., under the premise of meeting the same air purification capacity, the use of the plasma module 120 or the use intensity of the plasma module 120 is reduced as much as possible. At this time, the by-products brought by plasma purification are also reduced accordingly.

[0032] As to the above-described air purification gears, it should be understood that the aforementioned air purification gears can be automatically switched by the controller as described above, or manually switched by human. When performing the switching action, if the corresponding judgment condition is needed, the air purification device can also be configured with a sensor group 150 for sensing one or more parameters of volatile organic content, PM2.5, PM10, ozone content, room occupancy level, number of people, human temperature, positive / negative ion level and plasma level in the space to be treated. At this time, the controller can control the output voltage of the power supply module 130 to the positive / negative ion module 110 and / or the plasma module 120 based on one or more parameters sensed by the sensor group 150, so as to perform the automatic switching of the aforementioned air purification gears and improve the adaptive adjustment capability of the device.

[0033] Referring again to Figure 2 which shows another embodiment of the air purification device according to the present application. Compared with Figure 1Compared with the embodiments described above, the difference of the air purification device 100 is that the air purification device 100 has an external controller 140, and the air purification device 100 and the external controller 140 can communicate and transmit sensing signals or control commands through the communication module 400, so as to facilitate the customer to manually operate when needed, and improve the convenience. In addition, the air purification device also has the technical effects corresponding to the air purification device described in any of the above embodiments or their combinations, which will not be described here.

[0034] Specifically, the external controller 140 of the air purification device 100 can be installed in the form of a control panel in the space to be treated. On the one hand, it can be integrated with the sensor group 150 to improve the sensing accuracy of various parameters in the space; on the other hand, it can also be integrated with the temperature and humidity control module 170 to realize the adjustment of the air temperature and humidity in the space.

[0035] Further, the main part of the air purification device 100 can also be arranged at the air outlet 180 in the space to be treated, so that the air adjusted in temperature and humidity is further treated by the air purification device 100 before entering the room, and the quality of the adjusted air is improved. Alternatively, the main part of the air purification device 100 can also be arranged at the air return port in the space to be treated to achieve a similar effect.

[0036] In the above embodiments, it should be understood that the temperature and humidity adjustment function can be realized by configuring the corresponding hardware for the air purification device 100, or by integrating it with the air conditioning system 200 or communicating through the communication module 400. Due to the limited structure space of the air conditioning system 200, it is difficult to carry large air purification filter cartridges; and once the air conditioning equipment is installed, it is usually in a fixed state, so the replacement of the filter cartridge placed therein is more complicated. Such a modular air purification device 100 using ionization technology has low maintenance frequency and low space occupation, and has excellent compatibility with the air conditioning system 200.

[0037] Wherein, the skilled in the art should know that the air conditioning system proposed in the present application does not refer to the air conditioner with outdoor refrigeration / heat unit and indoor heat exchange unit in the industry in a narrow sense. It should be understood as a kind of heat system with air conditioning function, which is driven by various power sources (for example, electricity) to realize the heat exchange with the air at the location to be adjusted through the phase change of the refrigerant in the system. For example, when the air conditioning system is used in building heating, ventilation and air conditioning, it can be a refrigeration system with single cooling function, or a heat pump system with refrigeration and heating capacity. For another example, when the air conditioning system is used in the cold chain field, it can be a transport refrigeration system, or a refrigeration / freezing system. However, no matter what form of air conditioning system it is, there should be an air purification device to be applicable to the conception of the present application.

[0038] The above examples mainly illustrate the air purification device of the present application. Although only some embodiments of the present application are described, those skilled in the art should understand that the present application can be implemented in many other forms without departing from the spirit and scope of the present application. Therefore, the examples and embodiments shown are considered illustrative rather than limiting, and the present application can encompass various modifications and alternatives without departing from the spirit and scope of the present application as defined by the appended claims.
