[0041] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0042] like Figures 1 to 6 As shown, an embodiment of the present application provides an air purification device 100, including: a housing 4, a plasma discharge assembly, a catalyst module 3, and a first electrode connector 51 and a second electrode connector 52.

[0043] The housing 4 is provided with an air inlet 416, an air outlet 426 and a mounting portion, and the mounting portion is configured to mount the air purification device 100 on an air treatment device, such as Figures 11 to 18 The housing 4 is an insulating member, such as a plastic member.

[0044] The plasma discharge assembly is mounted on the housing 4. The plasma discharge assembly includes a discharge electrode 1 and a counter electrode 2 which are arranged with a relative spacing, and is arranged to discharge to generate active substances.

[0045] The catalyst module 3 is disposed in the housing 4 and is provided with an air passage communicating with the air inlet 416 and the air outlet 426. The catalyst module 3 is configured to cooperate with the active substance to purify the air. The catalyst of the catalyst module 3 may only have a catalytic effect, or the catalyst may have both a catalytic effect and an adsorption effect, that is, the catalyst may be an adsorption catalyst having both catalytic and adsorption effects.

[0046] The first electrode connector 51 and the second electrode connector 52 are installed on the housing 4 and are configured to be electrically connected to the power supply module. The first electrode connector 51 and the second electrode connector 52 are electrically connected to the discharge electrode 1 and the counter electrode 2, respectively, so that the power supply module can supply power to the plasma discharge assembly. The first electrode connector 51 is configured to be electrically connected to the high voltage end of the power supply module, and the second electrode connector 52 is configured to be connected to the low voltage end or the ground end of the power supply module. The power supply module can be a DC high voltage power supply.

[0047] The air purification device 100 provided in the embodiment of the present application can purify the air by utilizing the active substances generated by the discharge of the plasma discharge component and the synergistic effect of the catalyst of the catalyst module 3. Among them, the active substances may include: free radicals (such as oxygen free radicals (O·), hydroxyl free radicals (OH·), etc.), ozone, other active oxygen species (such as superoxide free radicals (O·-), etc.), which can degrade microorganisms such as bacteria in the air, organic pollutant molecules, and odor molecules to achieve the effect of purification and deodorization. The catalyst module 3 itself can decompose a part of the pollutants, and can also synergize with the active substances generated by the discharge of the plasma discharge component to improve the purification and deodorization effect, and can eliminate by-products such as ozone. In addition, the air purification device 100 does not have the situation where the traditional adsorption technology fails after saturation, and the catalyst can eliminate by-products such as ozone, and can also improve the mineralization rate of pollutants, which is conducive to avoiding secondary pollution.

[0048] Among them, the housing 4 can be used as a mounting carrier for the plasma discharge assembly, the catalyst module 3, the first electrode connector 51 and the second electrode connector 52, so that the air purification device 100 is modularized and easy to assemble. In addition, the housing 4 is provided with a mounting portion, so that the air purification device 100 can be conveniently mounted on the air treatment device through the mounting portion, which is conducive to reducing the difficulty of assembling the air purification device 100 and the air treatment device.

[0049] In some exemplary embodiments, along the gas flow direction of the gas passage, the catalyst module 3 is located on the downstream side of the plasma discharge assembly, so that the active substance is blown toward the catalyst module 3 under the action of the air flow, so that the active substance can fully contact with the catalyst module 3, which is beneficial to improve the collaborative purification efficiency.

[0050] like Figure 1 As shown, the discharge electrode 1 and the counter electrode 2 are arranged in a staggered manner along a first direction, and the first direction is parallel to the air inlet end surface 311 of the air inlet side 31 of the catalyst module 3. The first direction can be the length direction of the housing 4, which is conducive to increasing the number of electrodes, thereby improving the purification effect of the air purification device 100.

[0051] Each discharge electrode 1 is disposed adjacent to at least one counter electrode 2 and spaced apart from each other, and each counter electrode 2 is disposed adjacent to at least one discharge electrode 1. In other words, the discharge electrode 1 and the counter electrode 2 may be in a one-to-one relationship, a many-to-one relationship, or a one-to-many relationship.

[0052] The first electrode connector 51 is electrically connected to all the discharge electrodes 1, and the second electrode connector 52 is electrically connected to all the counter electrodes 2. In this way, all the discharge electrodes 1 and the counter electrodes 2 can be powered on at the same time by simply connecting the first electrode connector 51 and the second electrode connector 52 to the power supply module, which is conducive to simplifying the circuit connection structure of the air purification device 100.

[0053] In some embodiments, Figure 1 and Figure 3 As shown, there are multiple discharge electrodes 1, and the multiple discharge electrodes 1 are arranged at intervals along the first direction. Figure 1 and Figure 3 As shown, there are multiple counter electrodes 2, and the multiple counter electrodes 2 are arranged at intervals along the first direction. The multiple discharge electrodes 1 and the multiple counter electrodes 2 are arranged at intervals along the first direction.

[0054] In some exemplary embodiments, Figure 1 and Figure 3 As shown, the discharge electrode 1 and the counter electrode 2 extend in a second direction perpendicular to the first direction. The first electrode connector 51 and the second electrode connector 52 extend in the first direction and are spaced apart on both sides of the plasma discharge assembly in the second direction. The second direction may be the width direction of the housing 4.

[0055] In this way, the first electrode connector 51 and the second electrode connector 52 are far apart and will not affect or interfere with each other, which facilitates the connection between the first electrode connector 51 and the second electrode connector 52 and the power supply module.

[0056] In some exemplary embodiments, Figure 4 , Figure 5 and Figure 7 As shown, the housing 4 is provided with a first slot 411 and a second slot 412. Figure 7 As shown, the discharge electrode 1 has a first inserting piece 14 at one end in the length direction and a first connecting piece 15 at the other end. The counter electrode 2 has a second inserting piece 21 at one end in the length direction and a second connecting piece 22 at the other end.

[0057] like Figure 5As shown, the first plug sheet 14 is inserted into the first slot 411, the first connecting sheet 15, the first electrode connector 51 and the housing 4 are fixedly connected by fasteners, and the first connecting sheet 15 is electrically connected to the first electrode connector 51. Alternatively, the first connecting sheet 15 is electrically connected to the first electrode connector 51 by a fastener. The fastener may be, but is not limited to, a metal fastener, such as a screw. Alternatively, the first connecting sheet 15 is electrically connected to the first electrode connector 51 by contact, and the fastener may be a conductor or an insulator.

[0058] like Figure 4 As shown, the second plug-in sheet 21 is inserted into the second slot 412, the second connecting sheet 22, the second electrode connector 52 and the housing 4 are fixedly connected by fasteners, and the second connecting sheet 22 is electrically connected to the second electrode connector 52. Alternatively, the second connecting sheet 22 is electrically connected to the second electrode connector 52 by fasteners. The fasteners may be, but are not limited to, metal fasteners, such as screws. Alternatively, the second connecting sheet 22 is electrically connected to the second electrode connector 52 by contact, and the fasteners may be conductors or insulators.

[0059] In this way, the fixing method of the discharge electrode 1 and the counter electrode 2 is simple and reliable. In addition, the fastener not only realizes the fixed connection between the plasma discharge component and the housing 4, but also realizes the fixed connection between the first electrode connector 51 and the second electrode connector 52 and the housing 4, and also realizes the electrical connection between the plasma discharge component and the first electrode connector 51 and the second electrode connector 52, achieving three goals at one stroke, and effectively simplifying the assembly process of the air purification device 100.

[0060] The first plug 14 of the discharge electrode 1 and the second connecting piece 22 of the counter electrode 2 can be arranged at the same end in the second direction, and the first connecting piece 15 of the discharge electrode 1 and the second plug 21 of the counter electrode 2 are arranged at the same end in the second direction, so that the first electrode connector 51 and the second electrode connector 52 can be separated on both sides of the plasma discharge assembly.

[0061] The first inserting piece 14 and the first connecting piece 15 may have the same structure, so that the discharge electrode 1 can be installed in any direction. The second inserting piece 21 and the second connecting piece 22 may have the same structure, so that the discharge electrode 1 can be installed in any direction.

[0062] In some exemplary embodiments, Figure 4 and Figure 5 As shown, the first electrode connector 51 and the second electrode connector 52 are located outside the housing 4. The main body of the discharge electrode 1 and the main body of the counter electrode 2 are located inside the housing 4.

[0063] This can avoid discharge or arcing between the main body of the discharge electrode 1 and the second electrode connector 52 , or discharge or arcing between the main body of the counter electrode 2 and the first electrode connector 51 .

[0064] In some exemplary embodiments, the end of the discharge electrode 1 and the end of the counter electrode 2 are inserted into the housing 4, so that the first connecting piece 15 and the second connecting piece 22 are located outside the housing 4, such as Figure 4 and Figure 5 shown.

[0065] In this way, both ends of the discharge electrode 1 and the counter electrode 2 are limitedly matched with the shell 4, so it is convenient to use the shell 4 to locate the position of the discharge electrode 1 and the counter electrode 2, which is convenient for positioning first and then fixing, which is beneficial to improving assembly efficiency.

[0066] In some exemplary embodiments, the spacing between the plasma discharge assembly and the air inlet end surface 311 of the catalyst module 3 may be in the range of, but not limited to, 0 to 5 mm, such as 0, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc.

[0067] The distance between the discharge electrode 1 and the counter electrode 2 may be in the range of, but not limited to, 10 mm to 25 mm, such as 10 mm, 15 mm, 20 mm, 25 mm, etc.

[0068] In some exemplary embodiments, Figure 1 As shown, the discharge electrode 1 includes an electrode substrate 11 and a discharge portion 12 . The discharge portion 12 is disposed on the electrode substrate 11 and faces the counter electrode 2 .

[0069] Specifically, the discharge electrode 1 includes an electrode substrate 11 and a discharge portion 12, and the discharge portion 12 is arranged toward the counter electrode 2, so that after the plasma discharge component is energized, a discharge phenomenon can be generated between the discharge portion 12 of the discharge electrode 1 and the counter electrode 2, so that the generated high-energy active particles can cooperate with the catalyst to purify the air.

[0070] In some embodiments, a counter electrode 2 is disposed on one side of the discharge electrode 1, and a discharge portion 12 is disposed on the side of the electrode substrate 11 facing the counter electrode 2. This solution is conducive to simplifying the structure of the discharge electrode 1 and reducing the processing cost of the discharge electrode 1.

[0071] Or, if Figure 1 As shown, the opposite sides of the discharge electrode 1 are provided with counter electrodes 2, and the opposite sides of the electrode substrate 11 are provided with discharge parts 12. This solution is conducive to improving the discharge power and the space utilization rate of the air purification device 100.

[0072] In some embodiments, the electrode matrix 11 and the counter electrode 2 are both in the shape of rods or strips, and the length directions of the electrode matrix 11 and the counter electrode 2 are parallel. The cross-sections of the electrode matrix 11 and the counter electrode 2 may be circular or rectangular.

[0073] Among them, Figure 1 As shown, the discharge portion 12 is sawtooth-shaped and includes a plurality of sawteeth 121 sequentially arranged along the length direction of the electrode substrate 11, and the curvature radius of the outer surface of the counter electrode 2 is greater than the curvature radius of the tip of the sawteeth 121. The sawtooth-shaped discharge portion 12 may be provided on both sides of the electrode substrate 11, or the sawtooth-shaped discharge portion 12 may be provided only on one side of the electrode substrate 11.

[0074] Or, if Fig. 9 As shown, the discharge part 12 includes a plurality of discharge wires 122 sequentially arranged along the length direction of the electrode substrate 11, and the curvature radius of the outer surface of the counter electrode 2 is greater than the curvature radius of the outer surface of the discharge wire 122. The cross section of the discharge wire 122 may be circular or in other shapes.

[0075] In the discharge electrode 1, a plurality of spaced-apart sawtooth 121-shaped or filamentary discharge portions 12 are distributed along the length direction of the electrode substrate 11, which can increase the ionization efficiency of the air, improve the concentration of the generated active substances, and make the spatial distribution of the generated active substances more uniform, so as to better purify the air and remove odors.

[0076] like Fig. 9 As shown, the length directions of the electrode substrate 11 and the counter electrode 2 are arranged in parallel, and the multiple saw teeth 121 or multiple discharge wires 122 arranged on the electrode substrate 11 can be arranged along the extension direction of the electrode substrate 11, and the multiple saw teeth 121 or multiple discharge wires 122 are all facing the counter electrode 2, so as to improve the discharge efficiency between the discharge electrode 1 and the counter electrode 2, thereby increasing the ionization efficiency of the air and the concentration of the generated high-energy active particles, so that the spatial distribution of the generated high-energy active particles is more uniform, so as to better purify the air and remove odors.

[0077] The counter electrode 2 is arranged in a rod or strip shape, and the discharge portion 12 of the discharge electrode 1 is arranged in a sawtooth or filament shape, so that the curvature radius of the tip of the sawtooth 121 or the outer surface of the discharge filament 122 is smaller than the curvature radius of the outer surface of the counter electrode 2. The greater the difference between the curvature radius of the tip of the sawtooth 121 or the outer surface of the discharge filament 122 and the curvature radius of the outer surface of the counter electrode 2, the lower the voltage required to excite the discharge, and the more intense the discharge under the same voltage.

[0078] It is understandable that the discharge portion 12 is not limited to the sawtooth 121 and the discharge wire 122, and may also be configured as other structures with a small curvature radius, such as a needle tip shape, a wolf tooth shape, etc.

[0079] In other exemplary embodiments, Fig.10 As shown, the discharge electrode 1 includes an electrode wire 13, and the counter electrode 2 is in a rod or strip shape, and the curvature radius of the outer surface of the counter electrode 2 is greater than the curvature radius of the outer surface of the electrode wire 13. The cross section of the counter electrode 2 can be circular or rectangular, and the cross section of the electrode wire 13 can be circular or other shapes.

[0080] Specifically, the discharge electrode 1 is set to an electrode wire 13, and the outer surface of the electrode wire 13 has a small radius of curvature, while the counter electrode 2 is set to a rod or strip shape, and the outer surface of the counter electrode 2 has a large radius of curvature, so that the radius of curvature of the outer surface of the counter electrode 2 is much larger than the radius of curvature of the outer surface of the discharge electrode 1, and the radius of curvature of the outer surface of the electrode wire 13 of the discharge electrode 1 is small, and the voltage required to excite the discharge electrode 1 to discharge is low, and it is easier to generate more high-energy active particles. Therefore, this setting is conducive to the plasma discharge component being excited and discharged, and generating more high-energy active particles. In addition, the electrode wire 13 occupies less space and has a small flow resistance, which is also conducive to the circulation of air.

[0081] In some embodiments, Fig.10 As shown, the length directions of the electrode wire 13 and the counter electrode 2 are parallel, and the electrode wire 13 and the counter electrode 2 are alternately arranged.

[0082] Specifically, the electrode wire 13 and the counter electrode 2 are arranged in parallel in the length direction, so that the plasma discharge assembly has a good discharge effect and generates more high-energy active particles. The electrode wire 13 and the counter electrode 2 are arranged alternately, so that the non-thermal plasma generator generates more high-energy active particles in a limited space, and the generated active particles are more evenly distributed in space, and can more fully and evenly contact the catalyst loaded on the catalyst module 3 to cooperate with each other.

[0083] In some exemplary embodiments, the materials of the discharge electrode 1 and the counter electrode 2 are metals, and a modification material is provided on the surface.

[0084] Specifically, a modifying material is disposed on the metal material surface of the discharge electrode 1 and the counter electrode 2 to improve the conductivity of the discharge electrode 1 and the counter electrode 2 and to improve the discharge efficiency of the non-thermal plasma generator of the present application.

[0085] In some embodiments, the metal used for the discharge electrode 1 and the counter electrode 2 includes any one or more of stainless steel, copper, titanium, tungsten, and nickel. The modified material includes any one or more of noble metals, carbon nanotubes, and graphene. Among them, the noble metal includes any one or more of silver, platinum, palladium, ruthenium, rhodium, and gold.

[0086] Specifically, the corresponding metal and modification material can be selected according to the specific type of pollutants to be purified by the air purification device 100, working parameters, and the cost thereof.

[0087] In some exemplary embodiments, the catalyst module 3 includes a carrier and a catalyst loaded on the carrier. The catalyst includes any one or more of hydrotalcite, a molecular sieve modified by a transition metal and / or a noble metal, and alumina modified by a transition metal and / or a noble metal. Among them, the transition metal includes any one or more of manganese, cerium, iron, copper, nickel, and lanthanum, and the noble metal includes any one or more of silver, platinum, palladium, ruthenium, rhodium, and gold. According to the operating parameters of the air purification device 100, the corresponding filter metal and / or noble metal can be selected and set.

[0088] Specifically, hydrotalcite can be used as an alkaline catalyst, a redox catalyst, and a catalyst carrier. Hydrotalcite also has ion exchange and adsorption effects. Therefore, hydrotalcite can be selected as a catalyst loaded on an insulating honeycomb structure. Since transition metals and / or noble metals can catalyze and cross-couple organic compounds, the catalyst of the insulating honeycomb structure is set to a molecular sieve modified with transition metals and / or noble metals, or alumina modified with transition metals and / or noble metals, which can improve the degradation and decomposition of VOCs and the removal of odors of the air purification device 100 of the present application.

[0089] The corresponding catalyst may be selected according to the specific type of pollutants to be purified by the air purification device 100, the working parameters of the air purification device 100, the type of byproducts produced, and the cost of the air purification device 100 itself.

[0090] In some exemplary embodiments, the insulating honeycomb structure is a ceramic honeycomb structure, a glass fiber honeycomb structure, an alumina honeycomb structure, a fiberglass honeycomb structure, or a polymer honeycomb structure that meets a preset fire protection level requirement.

[0091] Since discharge needs to be excited between the discharge electrode 1 and the counter electrode 2, when selecting the polymer honeycomb structure, it is necessary to meet the preset fire protection level requirements. For example, the fire protection level of the polymer honeycomb structure can reach 5VA level, and the material can be ABS (acrylonitrile-butadiene-styrene terpolymer) plastic or ABS / PVC (polyvinyl chloride) mixed material or other plastics.

[0092] In some exemplary embodiments, Figures 4 to 8 As shown, the housing 4 includes a base 42 and a cover 41, and the cover 41 is connected to the base 42. The air inlet 416 is provided on the cover 41, and the air outlet 426 is provided on the base 42. The air inlet 416 can be in the shape of a grille 417, such as Figure 7 The air outlet 426 may be open, such as Figure 8 shown.

[0093] The catalyst module 3 is limited to the base 42 , and the plasma discharge assembly, the first electrode connector 51 and the second electrode connector 52 are fixed to the cover 41 .

[0094] In this way, it is convenient to first assemble the catalyst module 3 and the base 42 into one module, assemble the cover 41, the plasma discharge assembly, the first electrode connector 51 and the second electrode connector 52 into one module, and then assemble the two modules together.

By properly setting the height of the protrusion 4171, the distance between the discharge electrode 1 and the counter electrode 2 and the catalyst module 3 can be kept within a suitable range.

[0097] The mounting portion may be disposed on the base 42 , may be disposed on the cover 41 , or may be disposed on both the base 42 and the cover 41 .

[0098] In some exemplary embodiments, Figure 7 As shown, the outer wall of the cover body 41 is provided with a buckle 414, and the outer wall of the base 42 is provided with a buckle 424. The buckle 414 and the buckle 424 are buckled and fixed to make the cover body 41 and the base 42 cover and connect. Figure 1 and Figure 4 The clamping fixing method is simple, reliable and easy to operate. The base 42 and the cover 41 can also be fixed by positioning protrusions 423 (such as Figure 8 As shown) and the positioning hole 413 (as shown Figure 7 Pre-positioning is achieved.

[0099] The first electrode connector 51 and the second electrode connector 52 are fixed to the outer wall of the cover 41 . The first electrode connector 51 and the second electrode connector 52 are arranged to form a hollow strip structure.

[0100] In this way, the buckle 414 can also pre-position the first electrode connector 51 and the second electrode connector 52, so that the first electrode connector 51 and the second electrode connector 52 can be fixedly connected to the first connecting piece 15 and the second connecting piece 22 through fasteners after the positions of the first electrode connector 51 and the second electrode connector 52 are stabilized.

[0101] like Figure 1 and Figure 7 As shown, the buckles 414 can be arranged in two groups, and the two groups of buckles 414 are respectively arranged along the second direction on the two side walls of the cover body 41. The number of buckles 414 in each group can be multiple, and the multiple buckles 414 can be arranged at intervals along the first direction.

[0102] In some exemplary embodiments, Figure 1 , Figure 2 and Figure 8 As shown, the mounting portion includes an inserting portion 421 and a hooking portion 422. The inserting portion 421 is provided at one end of the housing 4 and is configured to be plugged into the air handling device; the hooking portion 422 is provided at the other end of the housing 4 and is configured to be hooked into the air handling device.

[0103] In this way, when installing the air purification device 100, you only need to insert one end of the air purification device 100 into the air treatment equipment and hang the other end on the air treatment equipment to achieve the assembly of the air purification device 100 and the air treatment equipment. The assembly method is simple, convenient and easy to operate.

[0104] The inserting portion 421 may be, but not limited to, a pin, a plug, a block, an insert column, etc. The hooking portion 422 may be, but not limited to, a "7"-shaped hook, an "n"-shaped hook, etc. The number of the inserting portions 421 may be multiple, and the number of the hooking portions 422 may be multiple.

[0105] In some embodiments, the inserting portion 421 and the hooking portion 422 are both disposed on the base 42 of the housing 4. Figure 8 shown.

[0106] like Figures 11 to 18 As shown, the embodiment of the present application also provides an air treatment device, including an air purification device 100 as in any one of the above embodiments, and thus has all the above beneficial effects, which will not be repeated here.

[0107] The types of air treatment equipment are not limited, such as air conditioners 200, air purifiers, sterilizers, humidifiers, dehumidifiers, etc., which have air treatment functions. The air purification device 100 can be installed at the air inlet of the air treatment equipment.

[0108] In some exemplary embodiments, the air purification device is provided with an air duct, and an air inlet grille 202 is provided at the entrance of the air duct, such as Fig.11 and Fig.13 The air inlet grille 202 is provided with an insertion hole 206 (such as Fig.16 As shown) and ribs 204 (as shown Fig.17 The air purification device 100 is arranged at the entrance of the air duct, as shown in FIG. Fig.11 , Fig.12 , Fig.13 As shown, the insertion portion 421 of the air purification device 100 is inserted into the insertion hole 206 (as shown in FIG. Fig.16 As shown), the hook portion 422 of the air purification device 100 is hooked on the rib 204 (as shown Fig.17 The air inlet grille 202 may be a part of the face frame 208 and located at the top of the face frame 208 of the wall-mounted air conditioner 200, as shown in FIG. Fig.11 and Fig.12 shown.

[0109] In this way, when installing the air purification device 100, you only need to insert one end of the air purification device 100 into the insertion hole 206 on the air inlet grille 202, and hang the other end on the rib 204 of the air inlet grille 202, so that the air purification device 100 and the air treatment equipment can be assembled. The assembly method is simple, convenient and easy to operate.

[0110] Moreover, this installation method can be adapted to most wall-mounted air conditioners 200, such as Figures 11 to 18 As shown, there is no need to design a special installation position on the air conditioner 200, and the versatility is strong. Compared with the existing large-area adsorption filter, the air purification device 100 provided in the embodiment of the present application is smaller in size, does not affect the air flow of the air conditioner 200, and has little impact on the cooling and heating performance of the air conditioner 200.

[0111] During use, the air in the indoor space circulates through the air duct and is purified by the air purification device 100 in the process of flowing through the air duct, thereby achieving the effect of purifying the air in the indoor space.

[0112] In one embodiment, the overall size of the device of the plasma purification device is 155mm*75mm*20mm. Among them, the cover body 41 is designed with an air inlet 416 in the shape of a rectangular grid 417, and the cover body 41 is equipped with an electrode pair consisting of 4 high-voltage electrodes (i.e., discharge electrode 1) and 3 low-voltage electrodes (i.e., counter electrode 2), and the spacing between the high-voltage electrode and the low-voltage electrode is 10mm. Among them, the high-voltage electrode is in the form of a needle tip, and the low-voltage electrode is in the form of a strip metal sheet, both of which are made of 316L stainless steel. The outer electrode connector (the first electrode connector 51 and the second electrode connector 52) also uses a metal material with good conductivity. The size of the catalyst module 3 is 135mm*60mm*10mm, and it is made by spraying a Beta-type molecular sieve mixed with oxides of two metals, Mn and Ce, on a cordierite ceramic honeycomb. The catalyst module 3 is fixed inside the base 42, and the base 42 and the cover body 41 are fixed by a buckle 414. At this time, the distance between the high and low voltage electrode pairs and the catalyst module 3 is 1mm. The entire purification device is fixed to the air duct entrance of the wall-mounted air conditioner 200 by means of latches and hooks.

[0113] The method of purifying and treating pollutants by using this embodiment is as follows: when the user starts the purification function, the air purification device 100 is powered on, and a 12V low-voltage DC power supply is input. The high-voltage package of the module converts the 12V low-voltage DC power into a +5kV high-voltage DC power and applies it to the plasma discharge component. A plasma discharge phenomenon is generated between the high-voltage electrode and the low-voltage electrode of the module. At this time, the operating current is 0.3mA and the output power is 1.5W. At this time, the air conditioner 200 starts the wind wheel to supply air, and the gas containing pollutants flows through the catalyst module 3 and is captured and catalytically degraded by the active substances generated by the plasma. The clean air is transported back to the room through the air duct outlet. After multiple air circulations (about 1-2 hours), most of the pollutants and odor molecules are catalytically degraded, and finally the odor in the room is removed and the air is purified.
