[0003] However, the air treatment device carried by the existing air conditioner uses photocatalysis or plasma technology to degrade the adsorbed VOCs, and there are still harmful intermediate products during degradation. CONTENT OF THE UTILITY MODEL

[0013] The housing comprises:

[0014] A catalytic cabin is formed with the accommodating cavity and an opening communicating with the accommodating cavity;

[0015] A cabin door is slidably connected to the catalytic cabin, and the cabin door can slide away from the opening or close the opening relative to the catalytic cabin;

[0016] Among them,

[0018] The driving assembly is arranged in the catalytic cabin, the driving assembly is connected to the cabin door, the driving assembly is used to drive the cabin door to slide away from the opening to move the adsorption assembly out of the catalytic cabin, and is used to drive the cabin door to slide to close the opening to move the adsorption assembly into the accommodating cavity.

[0019] By driving the cabin door to slide away from the opening relative to the catalytic cabin, at this time, the adsorption assembly slides away from the opening and slides from the accommodating cavity to the outside of the catalytic cabin, which facilitates the adsorption of the adsorption assembly to the pollutants in the air. The driving assembly drives the cabin door to slide relative to the catalytic cabin to close the opening, at this time, the adsorption assembly slides to the accommodating cavity, and heating is performed to increase the temperature in the accommodating cavity, so that the pollutants adsorbed by the adsorption assembly can fall off from the adsorption assembly to the catalytic component, and the catalytic component can catalyze the pollutants at high temperature to degrade into harmless carbon dioxide and water. The decomposition efficiency of the pollutants is high, and no secondary pollution is caused.

[0020] In another aspect, the application discloses an air treatment device, comprising:

[0021] An adsorption assembly is used to adsorb pollutants;

[0022] A catalytic assembly is used to catalyze the pollutants;

[0029] a catalytic cabin, the catalytic cabin being formed with the accommodating cavity and an opening in communication with the accommodating cavity;

[0030] a cabin door, the cabin door being slidably connected to the catalytic cabin;

[0031] wherein the cabin door is provided with the adsorption assembly,

[0032] the cabin door is used to slide relative to the catalytic cabin under the driving of the driving assembly to open the opening and make the adsorption assembly located outside the catalytic cabin, and close the opening and make the adsorption assembly located in the accommodating cavity.

[0033] By driving the cabin door to slide away from the opening relative to the catalytic cabin through the driving assembly, at this time, the adsorption assembly slides away from the opening from the accommodating cavity to the outside of the catalytic cabin, which facilitates the adsorption of the adsorption assembly to the pollutants in the air. While the driving assembly drives the cabin door to slide relative to the catalytic cabin to close the opening, at this time, the adsorption assembly slides to the accommodating cavity, and heating is performed, which can increase the temperature in the accommodating cavity, so that the pollutants adsorbed by the adsorption assembly can fall off from the adsorption assembly to the catalytic component, and the catalytic component can catalyze the pollutants at high temperature to degrade into harmless carbon dioxide and water, the decomposition efficiency of the pollutants is high, and secondary pollution is not caused.

[0034] In some embodiments of the present application, the adsorption assembly comprises:

[0035] a support, the support being arranged on a side of the cabin door facing the catalytic cabin, the support being provided with a plurality of through holes;

[0036] an adsorption component, the adsorption component being arranged in the support, the adsorption component being configured to have a porous structure and being provided with a plurality of through holes.

[0037] By arranging the adsorption component in the support, the adsorption component can slide into the accommodating cavity or slide out of the catalytic cabin along with the cabin door. Moreover, the adsorption effect of the adsorption component with a porous structure is better, and the through holes are avoided to avoid the support hindering the adsorption or desorption of the pollutants to or from the adsorption component.

[0038] In some embodiments of the present application, the material of the adsorption component comprises one or more of activated carbon, mesoporous carbon, molecular sieve, and metal organic framework compound.

[0039] By providing the adsorption component with a plurality of different materials, the actual situation can be selected, which is not specifically limited in the present embodiment.

[0040] In some embodiments of the present application, the shell comprises a sliding mechanism, and the shell comprises:

[0041] Sliding mechanism;

[0044] Alternatively, the sliding mechanism includes:

[0045] a slide rail, the slide rail being arranged on the catalytic chamber;

[0046] A slider is slidably connected to the slide rail, and the hatch is connected to the slider.

[0047] By providing different sliding mechanisms, a selection can be made based on practical needs, and this embodiment does not impose specific limitations. When the sliding mechanism utilizes a telescopic rod, sliding stability is increased, and the telescopic rod saves movement space, facilitating a miniaturized design of the air treatment device. When the sliding mechanism utilizes a slider or a rail, the structure is relatively simple, and the design difficulty is relatively low.

[0054] A second heat insulation plate is provided on a side of the first heat insulation plate facing away from the catalytic chamber.

[0055] The first insulation board is slidably connected to the catalytic chamber. When the opening is closed, the insulation board forms a sealed space within the chamber, reducing heat dissipation from the heating component and saving energy. Furthermore, the insulation provided by the first insulation board further prevents heat from dissipating from the opening to the outside of the catalytic chamber. Furthermore, the insulation provided by the second insulation board further prevents heat from dissipating from the opening to the outside of the catalytic chamber, creating a double insulation effect with the first insulation board, further enhancing the insulation effect.

[0058] In some embodiments of the present application, the catalytic cabin is provided with a containing groove on the side facing the cabin door, and the sealing ring is embedded in the containing groove.

[0059] By embedding the sealing ring in the containing groove, the space occupied by the sealing ring can be reduced, which is beneficial to the miniaturization design of the air treatment device. Moreover, the assembly precision of the sealing ring and the catalytic cabin is higher, and the sealing effect is better.

[0061] a detection component for detecting the concentration of pollutants;

[0062] a control component electrically connected to the detection component and the driving assembly;

[0063] The control component is used to calculate the concentration drop rate according to the concentration of the pollutants, and when the concentration drop rate is less than a preset value, the driving assembly is controlled to drive the cabin door to slide and close the opening so that the adsorption assembly moves into the containing cavity.

[0064] By detecting the concentration of pollutants in the air by the detection component, the control component can know the concentration of pollutants in the construction period, and by calculating the concentration drop rate according to the concentration of pollutants by the control component, and when the concentration drop rate is less than a preset value, it is determined that the adsorption component is in a saturated state. At this time, the driving assembly is controlled to drive the cabin door to slide and close the opening so that the adsorption assembly moves into the containing cavity, and the pollutants adsorbed by the adsorption component are catalytically degraded, which can reduce energy consumption and has a high degree of automation.

[0065] In some embodiments of the present application, the wall of the containing cavity is provided with a heat insulation material.

[0066] By providing a heat insulation material on the wall of the containing cavity, when the heating component heats to increase the temperature in the containing cavity, the heat radiation to the outside of the containing cavity can be blocked, and the heat dissipation to the outside of the containing cavity is minimized, thereby saving energy consumption.

[0067] In some embodiments of the present application, the catalytic cabin is provided with an air hole, which is communicated with the containing cavity.

[0068] The gas generated in the catalytic degradation process of the pollutants can be discharged from the accommodating cavity through the air holes, so as to keep the air pressure balance inside and outside the accommodating cavity.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0104] Before the technical solutions of the present application are explained, the inventive concept of the present application will be explained.

[0105] Figure 1 It is a structural diagram of an air-conditioning indoor unit 1000 provided in an embodiment of the present application. Figure 1 It is a schematic diagram of the exploded structure of an air-conditioning indoor unit 1000 provided in an embodiment of the present application. Figure 3 1 is a schematic diagram of the structure of an air treatment device 100 provided in an embodiment of the present application. Figures 1 to 3 As shown, the air treatment device 100 is a device installed on the housing 200 of the air conditioner indoor unit 1000, and is used to adsorb and catalyze pollutants in the air at high temperature, thereby reducing the concentration of pollutants in the air.

[0106] In the related art, the air treatment device 100 uses photocatalysis or plasma technology to degrade the adsorbed VOCs, and degrades them while adsorbing them. The problems it has are at least as follows:

[0107] One is that when these two technologies degrade VOCs, the pollutants are not completely purified and high concentrations of ozone or other harmful intermediates are produced. These substances will cause secondary pollution when released into the air.

[0108] The second is that degradation occurs during adsorption. For adsorption materials with limited regeneration times, the service life of the adsorption materials is short.

[0109] The third is that the adsorption material is always exposed to the air. Dust, particulate matter, bacteria, etc. in the air will be deposited on the adsorption material, causing pollution to the adsorption material and reducing the service life of the adsorption material.

[0110] The following will be combined with the accompanying drawings of some embodiments of the present application to clearly and completely describe the technical solutions of some embodiments of the present application. Obviously, the embodiments described are only some embodiments of the present application, not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of this application.

[0111] In some embodiments, as Figure 1 and Figure 2 As shown, the air conditioner indoor unit 1000 includes a housing 200, which forms an inner cavity and an air outlet 200a communicating with the inner cavity.

[0112] The shape of the inner cavity can be cylindrical or rectangular, etc. Of course, the inner cavity can be in other possible shapes, which are not limited in this embodiment. The air outlet 200a can provide a channel for the air in the inner cavity to be blown out of the housing 200.

[0113] In some embodiments, the air conditioning indoor unit 1000 includes a fan (not shown), which is disposed in the inner cavity.

[0114] By setting the fan in the inner cavity, the fan can quickly blow the air in the inner cavity after heat exchange to the indoor where the air conditioner indoor unit 1000 is located, and the refrigeration effect of the air conditioner indoor unit 1000 is better.

[0115] In some embodiments, as shown in Figure 1 The air conditioner indoor unit 1000 includes an air treatment device 100, and the air treatment device 100 is arranged at the air outlet 200a.

[0116] By setting the air treatment device 100 at the air outlet 200a, the air treatment device 100 is used to adsorb and high-temperature catalyze the pollutants in the air, so as to reduce the concentration of the pollutants in the air.

[0117] The air treatment device 100 provided by the embodiment of the present application can have various implementation forms, for example, can be applied to air conditioner indoor units 1000, air purifiers, range hoods, etc., and the embodiment does not make specific limitation hereon. Figure 1 One application mode of the air treatment device 100 provided by the embodiment of the present application is applied to the air conditioner indoor unit 1000.

[0118] In some embodiments, as shown in Figure 2 The air treatment device 100 includes an adsorption assembly 10, and the adsorption assembly 10 is used to adsorb the pollutants.

[0119] By adsorbing the pollutants through the adsorption assembly 10, the concentration of the pollutants in the air can be reduced, and preparation for degrading the pollutants is provided.

[0120] In some embodiments, the air treatment device 100 includes a catalysis assembly 20, and the catalysis assembly 20 is used to catalyze the pollutants.

[0121] By catalyzing the pollutants through the catalysis assembly 20, the pollutants can be degraded, so that the adsorption assembly 10 can continue to adsorb the pollutants in the air, thereby forming an adsorption-degradation-adsorption cycle.

[0122] In some embodiments, the air treatment device 100 includes a driving assembly 30, and the driving assembly 30 is used to drive the adsorption assembly 10 to move into or out of the catalysis assembly 20.

[0123] By driving the adsorption assembly 10 to move out of the catalysis assembly 20 through the driving assembly 30, the adsorption assembly 10 can adsorb the pollutants in the air, and when the driving assembly 30 drives the adsorption assembly 10 to move into the catalysis assembly 20, the catalysis assembly 20 can catalyze and degrade the pollutants adsorbed by the adsorption assembly 10.

[0124] In some embodiments, as shown in Figure 3 andFigure 4 As shown, the catalytic assembly 20 comprises a shell 21, which forms a containing cavity 21a, and the driving assembly 30 is used to drive the adsorption assembly 10 to move into the containing cavity 21a or outside the shell 21.

[0125] Wherein, Figure 3 As shown, the adsorption assembly 10 is located outside the shell 21, Figure 4 As shown, the adsorption assembly 10 is located in the containing cavity 21a.

[0126] By forming the containing cavity 21a through the shell 21, the driving assembly 30 drives the adsorption assembly 10 to move outside the catalytic assembly 20, at this time, the adsorption assembly 10 can adsorb the pollutants in the air, and when the driving assembly 30 drives the adsorption assembly 10 to move into the catalytic assembly 20, the catalytic assembly 20 can catalytically degrade the pollutants adsorbed by the adsorption assembly 10. Moreover, the adsorption assembly 10 located in the containing cavity 21a will not be exposed to the indoor air, which can avoid the situation that the dust, particulate matter, bacteria and the like in the air will deposit on the adsorption material and pollute the adsorption material, and the service life of the adsorption material is longer.

[0127] In some embodiments, as shown, Figure 5 The catalytic assembly 20 comprises a heating component 22, which is arranged in the containing cavity 21a.

[0128] By heating in the containing cavity 21a through the heating component 22, the temperature in the containing cavity 21a can be increased, so that the pollutants adsorbed by the adsorption assembly 10 can fall off from the adsorption assembly 10, and the catalytic assembly 20 can catalyze the pollutants adsorbed by the adsorption assembly 10 at high temperature.

[0129] Wherein, the temperature at which the pollutants fall off (i.e., desorb) from the adsorption assembly 10 can be 40℃-80℃.

[0130] Wherein, the temperature at which the catalytic assembly 20 catalyzes the pollutants at high temperature can be 100℃-250℃.

[0131] In some embodiments, the heating component 22 can be a polyimide heating film, a PTC ceramic piece, a resistance wire, etc., which can be selected according to the actual situation, and the present embodiment does not make specific limitation thereto.

[0132] In some embodiments, the catalytic assembly 20 comprises a catalytic component 23, which is arranged in the containing cavity 21a, and the catalytic component 23 is used to catalyze the pollutants.

[0133] Wherein, the catalytic component 23 comprises a catalyst slurry and a carrier, the catalyst slurry can be loaded on the carrier by spraying, dipping, rolling and the like, and the catalyst slurry comprises a catalyst, an adhesive, a heat-conducting agent and the like mixed in a certain proportion.

[0134] In some embodiments, the material of the catalytic component 23 comprises one or more of transition metal oxides, multinary metal oxide composites.

[0135] By providing catalytic components 23 of different materials, the actual situation can be selected, which is not specifically limited in the embodiments.

[0136] In some embodiments, as shown in Figure 6 The housing 21 comprises a catalytic cabin 211, which is formed with a containing cavity 21a and an opening 211a in communication with the containing cavity 21a.

[0137] By forming the containing cavity 21a with the catalytic cabin 211, the catalytic component 23 and the heating component 22 can be arranged in the containing cavity 21a, so as to catalyze the pollutants at high temperature in the containing cavity 21a. Moreover, by arranging the opening 211a in communication with the containing cavity 21a, the adsorption assembly 10 can be moved into the containing cavity 21a or outside the catalytic cabin 211 through the opening 211a.

[0138] In some embodiments, the housing 21 comprises a cabin door 212, which is slidably connected to the catalytic cabin 211, and the cabin door 212 can slide away from the opening 211a or close the opening 211a relative to the catalytic cabin 211.

[0139] As shown in Figure 3 and Figure 4 As shown in Figure 3 the cabin door 212 is shown sliding away from the opening 211a, Figure 4 the cabin door 212 is shown closing the opening 211a.

[0140] By sliding the cabin door 212 away from the opening 211a relative to the catalytic cabin 211, at this time, the opening 211a is open, and the adsorption assembly 10 can adsorb the pollutants in the air outside the catalytic cabin 211. When the cabin door 212 closes the opening 211a, the containing cavity 21a forms a closed space, which can reduce the heat dissipation of the heating component 22, save energy consumption, and avoid the situation that the pollutants are dissipated outside the catalytic cabin 211 to cause secondary pollution when they are not timely catalyzed and degraded.

[0141] In some embodiments, the adsorption assembly 10 is arranged on the side of the cabin door 212 facing the catalytic cabin 211, and the driving assembly 30 is arranged in the catalytic cabin 211. The driving assembly 30 is connected to the cabin door 212, and the driving assembly 30 is used to drive the cabin door 212 to slide away from the opening 211a so as to move the adsorption assembly 10 outside the catalytic cabin 211, and is used to drive the cabin door 212 to slide to close the opening 211a so as to move the adsorption assembly 10 into the containing cavity 21a.

[0142] When the driving assembly 30 drives the cabin door 212 to slide away from the opening 211a, the adsorption assembly 10 provided on the cabin door 212 slides away from the opening 211a and slides out of the containing cavity 21a to the outside of the catalytic cabin 211, so as to facilitate the adsorption assembly 10 to adsorb the pollutants in the air. When the driving assembly 30 drives the cabin door 212 to slide to close the opening 211a, the adsorption assembly 10 provided on the cabin door 212 slides into the containing cavity 21a, so as to facilitate the pollutants adsorbed by the adsorption assembly 10 to be dropped to the catalytic component 23 for high-temperature catalysis. Moreover, the steps of adsorbing the pollutants by the adsorption assembly 10 and catalytically degrading the pollutants by the catalytic component 23 are performed separately, so as to prolong the service life of the adsorption material.

[0143] In some embodiments, the cabin door 212 is slidably connected to the catalytic cabin 211, and the cabin door 212 is provided with the adsorption assembly 10. The cabin door 212 is used to slide relative to the catalytic cabin 211 under the driving of the driving assembly 30, so as to open the opening 211a and make the adsorption assembly 10 located outside the catalytic cabin 211, and close the opening 211a and make the adsorption assembly 10 located in the containing cavity 21a.

[0144] In some embodiments, the cabin door 212 is slidably connected to the catalytic cabin 211, and the cabin door 212 is provided with the adsorption assembly 10. The cabin door 212 is used to slide relative to the catalytic cabin 211 under the driving of the driving assembly 30, so as to open the opening 211a and make the adsorption assembly 10 located outside the catalytic cabin 211, and close the opening 211a and make the adsorption assembly 10 located in the containing cavity 21a.

[0145] In some embodiments, as shown in Figure 7 and Figure 8 The adsorption assembly 10 comprises a support 11, and the support 11 is provided on the side of the cabin door 212 facing the catalytic cabin 211. The support 11 is provided with a plurality of through holes 11a.

[0146] By providing the support 11 on the side of the cabin door 212 facing the catalytic cabin 211, the support 11 can provide support for the adsorption material for adsorbing the pollutants, and the through holes 11a can be avoided, so as to facilitate the adsorption material to adsorb the pollutants and facilitate the pollutants adsorbed by the adsorption material to drop to the catalytic component 23 for catalytic degradation.

[0147] In some embodiments, the adsorption assembly 10 comprises an adsorption component 12, and the adsorption component 12 is provided on the support 11. The adsorption component 12 is configured to have a porous structure and is provided corresponding to the plurality of through holes 11a.

[0148] The adsorption component 12 is arranged on the support 11, and the adsorption component 12 can slide into the containing cavity 21a or slide out of the catalytic cabin 211 along with the cabin door 212. In addition, the adsorption effect of the adsorption component 12 with a porous structure is good, and the support 11 is avoided from hindering the adsorption or desorption of pollutants to or from the adsorption component 12 through the through hole 11a.

[0149] In some embodiments, the material of the adsorption component 12 includes one or more of activated carbon, mesoporous carbon, molecular sieve, and metal organic framework compound.

[0150] By providing the adsorption component 12 with a plurality of different materials, selection can be made according to actual conditions, which is not specifically limited in the present embodiment.

[0151] In some embodiments, as shown in FIGS. 1 and 2, the shell 21 includes a sliding mechanism 40, and the sliding mechanism 40 includes at least two telescopic rods. Figure 7 and Figure 9 As shown in FIGS. 1 and 2, the shell 21 includes a sliding mechanism 40, and the sliding mechanism 40 includes at least two telescopic rods, one end of each of the at least two telescopic rods is arranged on the two sides of the catalytic cabin 211, and the other end of each of the at least two telescopic rods is connected to the cabin door 212.

[0152] The cabin door 212 is driven to slide relative to the catalytic cabin 211 by the at least two telescopic rods, the stability of the sliding is high, and the telescopic rods can save movement space, which is conducive to the miniaturization design of the air treatment device 100.

[0153] In some embodiments, the shell 21 includes a sliding mechanism 40, and the sliding mechanism 40 includes a sliding rail and a sliding block, the sliding rail is arranged on the catalytic cabin 211, the sliding block is slidably connected to the sliding rail, and the cabin door 212 is connected to the sliding block.

[0154] The slidable design of the cabin door 212 and the catalytic cabin 211 is realized by the sliding block and the sliding rail, the structure is relatively simple, and the design difficulty is low.

[0155] In some embodiments, the driving assembly 30 includes a driving component 31, and the driving component 31 is arranged in the catalytic cabin 211.

[0156] The driving component 31 provides driving force, which can realize the automatic control of the sliding of the cabin door 212 relative to the catalytic cabin 211, without the need for manual operation by the user, and the user experience is good.

[0157] In some embodiments, the driving assembly 30 includes a transmission mechanism 32, the transmission mechanism 32 is a belt pulley mechanism, and the transmission mechanism 32 is connected to the driving component 31 and the telescopic rod.

[0158] When the driving component 31 provides driving force, the transmission mechanism 32 is used for step-by-step transmission by the belt pulley mechanism, so that the telescopic rod is elongated or shortened, thereby driving the cabin door 212 to slide relative to the catalytic cabin 211.

[0159] In some embodiments, as shown in Figure 7 and Figure 8 , the hatch 212 comprises a first heat insulation plate 212a, which is slidably connected to the catalytic cabin 211.

[0160] By being slidably connected to the catalytic cabin 211 through the first heat insulation plate 212a, the heat insulation plate can form a closed space when the opening 211a is closed, reducing the heat dissipation of the heating component 22, and saving energy consumption. At the same time, by using the heat insulation effect of the first heat insulation plate 212a, the heat dissipation from the direction of the opening 211a to the outside of the catalytic cabin 211 can be further hindered.

[0161] In some embodiments, the hatch 212 comprises a second heat insulation plate 212b, which is arranged on the side of the first heat insulation plate 212a away from the catalytic cabin 211.

[0162] By the heat insulation effect of the second heat insulation plate 212b, the heat dissipation from the direction of the opening 211a to the outside of the catalytic cabin 211 can be further hindered, forming double heat insulation with the first heat insulation plate 212a, and the heat insulation effect is more obvious.

[0163] In some embodiments, as shown in Figure 6 and Figure 10 , the side of the catalytic cabin 211 facing the hatch 212 is provided with a sealing ring 50, which is used to abut against the hatch 212 when the hatch 212 closes the opening 211a.

[0164] By pressing the sealing ring 50 between the hatch 212 and the catalytic cabin 211, the sealing degree of the hatch 212 closing the opening 211a is higher, which can improve the air tightness of the closed space formed by the containing cavity 21a, and the heat insulation effect is better.

[0165] In some embodiments, the side of the catalytic cabin 211 facing the hatch 212 is provided with a containing groove 211b, and the sealing ring 50 is embedded in the containing groove 211b.

[0166] By embedding the sealing ring 50 in the containing groove 211b, the space occupied by the sealing ring 50 can be reduced, which is conducive to the miniaturization design of the air treatment device 100. Moreover, the assembly precision of the sealing ring 50 and the catalytic cabin 211 is higher, and the sealing effect is better.

[0167] In some embodiments, the air treatment device 100 comprises a detection component (not shown), which is used to detect the concentration of pollutants.

[0168] By detecting the concentration of pollutants in the air through the detection component, the air treatment device 100 can take the action of adsorbing and catalytically degrading the pollutants according to the concentration of the pollutants, and the degree of automation is higher.

[0169] In some embodiments, the air treatment device 100 comprises a control component (not shown) electrically connected to the detection component and the driving assembly 30, which is used to calculate the concentration drop rate according to the concentration of the pollutants, and control the driving assembly 30 to drive the hatch 212 to slide to close the opening 211a to move the adsorption assembly 10 into the containing cavity 21a when the concentration drop rate is less than a preset value.

[0170] By using the control component to calculate the concentration drop rate according to the concentration of the pollutants, and controlling the driving assembly 30 to drive the hatch 212 to slide to close the opening 211a to move the adsorption assembly 10 into the containing cavity 21a when the concentration drop rate is less than a preset value, i.e., determining that the adsorption component 12 is in a saturated state, and catalytically degrading the pollutants adsorbed by the adsorption component 12, the energy consumption can be reduced, and the degree of automation is higher.

[0171] In some embodiments, the wall of the containing cavity 21a is provided with a heat insulation material.

[0172] By providing the wall of the containing cavity 21a with a heat insulation material, when the heating component 22 heats to increase the temperature in the containing cavity 21a, the heat radiation to the outside of the containing cavity 21a can be blocked, the heat dissipation to the outside of the containing cavity 21a is minimized, and the energy consumption is saved.

[0173] In some embodiments, the catalytic cabin 211 is provided with an air hole 211c which is communicated with the containing cavity 21a.

[0174] By communicating the containing cavity 21a with the air hole 211c, the gas generated in the process of catalytic degradation of the pollutants can be discharged from the containing cavity 21a through the air hole 211c, and the air pressure balance inside and outside the containing cavity 21a is maintained.
