Description

Technical Field

[0001] The present application relates to but is not limited to the field of air purification technology, and specifically refers to an air purification module, air treatment equipment, and a control method and control device thereof. Background Art

[0002] At present, the air purification module on the air treatment equipment with air purification function (such as household purifiers or air conditioners) mainly uses adsorption purification, and the adsorbent is made into a filter pre-installed in the air treatment equipment or directly integrated in the air treatment equipment. When the adsorbent reaches the end of its service life or fails, the user needs to manually disassemble the air purification module or replace the filter.

[0003] In order to avoid replacing the adsorbent, the adsorbent can also be regenerated. However, the regeneration of the adsorbent usually requires high-temperature heating or light, which is difficult to regenerate in a home environment. The air purification module that uses heating or light adsorption regeneration is mainly in the form of a rotary wheel, that is, a rotating disc is used to complete the cycle of adsorption and regeneration. Half of the area of ​​the disc is first exposed to the purification air duct for adsorption. As the disc rotates, it is sent into the regeneration air duct for regeneration, and the other half of the disc that has been regenerated moves to the purification air duct for adsorption accordingly. This alternating reciprocation finally achieves the effect of regeneration and purification. Although this adsorption regeneration scheme can achieve adsorbent regeneration in a home environment, there are new problems, namely: the space occupied by the disc is large, and special purification air ducts and regeneration air ducts need to be designed. It is less applicable to scenes with strict air volume requirements.

[0004] There are also solutions that use photocatalytic regeneration and plasma regeneration, but due to the low energy density, the energy and time required for regeneration are relatively long. Therefore, for relatively low-priced adsorbents, replacement is generally adopted. However, for relatively high-priced adsorbents, regeneration is an urgent problem to be solved. Summary of the invention

[0005] The technical problem to be solved by the present application is to provide an air purification module, air treatment equipment and a control method and a control device thereof, which can realize efficient regeneration of the adsorbent in a home environment and have good applicability to scenarios with stricter air volume requirements.

[0006] An embodiment of the present application provides an air purification module, comprising: a frame, the frame being provided with an airflow channel; a frame door, movably connected to the frame and configured to move relative to the frame between a closed position for closing the airflow channel and an open position for conducting the airflow channel; an adsorption module, disposed in the airflow channel and configured to purify the gas flowing through the airflow channel; and a regeneration module, configured to regenerate the adsorption module.

[0007] The air purification module provided in the embodiment of the present application includes a frame, a frame door, an adsorption module and a regeneration module. The frame is an installation carrier for the frame door and the adsorption module. The adsorption module is used to adsorb pollutants in the gas to achieve the function of purifying the air. The regeneration module is used to regenerate the adsorption module to achieve the regeneration of the adsorbent and avoid replacing the adsorption module. The frame door is used to realize the opening and closing of the air flow channel in the frame, so that the frame has the function of supporting the adsorption module and circulating air, and also has the function of creating a relatively independent closed regeneration space. When the air needs to be purified, the frame door moves to the open position, the air flow channel is opened, and the air in the space to be purified can enter the air flow channel, and flow out after being purified by the adsorption module in the air flow channel. When the adsorption module needs to be regenerated, the frame door moves to the closed position, the air flow channel is closed, and a closed regeneration space is formed in the frame. Compared with the purification air duct of the air handling equipment, the enclosed regeneration space in the frame is much smaller. Therefore, the energy generated by the regeneration module in the air flow channel can only regenerate the adsorption module in the enclosed regeneration space, and cannot diffuse to the external purification air duct. This can effectively increase the energy density used for the regeneration of the adsorption module, which is conducive to the rapid regeneration of the adsorption module.

[0008] Moreover, compared with the disc adsorption regeneration solution, the air purification module of this solution does not need to set up dedicated purification air ducts and regeneration air ducts. The purification process and the regeneration process are both carried out in the air flow channel of the frame, so it occupies a small space and can be directly installed in the purification air duct (also called the main air duct) of the air treatment equipment. It can be used in home environments and overcomes the problem of poor applicability of the turntable regeneration solution to scenarios with strict air volume requirements.

[0009] An embodiment of the present application also provides an air treatment device, comprising an air purification module as described in any one of the above embodiments.

[0010] The present application also provides a control method for the air treatment device according to the above embodiment, the control method comprising:

[0011] Determining a target operating mode, wherein the target operating mode includes a purification mode and a regeneration mode;

[0012] The air purification module is controlled according to a determined target operating mode; wherein, in the purification mode, the frame door is controlled to move to the open position to open the air flow channel; in the regeneration mode, the frame door is controlled to move to the closed position to close the air flow channel, and the regeneration module is controlled to operate to regenerate the adsorption module.

[0013] An embodiment of the present application further provides a control device, including a processor and a memory storing a computer program, wherein the processor implements the steps of the control method described in any one of the above embodiments when executing the computer program.

[0034] 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.

[0035] Research has found that the air purification modules using photocatalytic regeneration and plasma regeneration have a lower energy density, resulting in a longer energy and time required for regeneration. The reason is that the photocatalytic modules or plasma generating modules of these schemes directly release the regeneration energy generated during the regeneration process into the purified air duct. Since the purified air duct space is relatively large, the regeneration energy is easily diffused in the purified air duct, resulting in a relatively small proportion of energy that actually acts on the adsorbent regeneration. Therefore, the energy density used for adsorbent regeneration is also relatively small, resulting in a longer energy and time required for regeneration.

[0036] For this reason, Figures 1 to 12 As shown, an embodiment of the present application provides an air purification module, including: a frame 1, a frame door 2, an adsorption module 3 and a regeneration module 4.

[0037] The frame 1 is provided with an air flow channel 11, such as Figure 2 The frame door 2 is movably connected to the frame 1 and is arranged to be in a closed position (such as Figure 1 , Figure 3 ) and the open position of the conducting air flow channel 11 (as shown Figure 2 , Figure 4 and Figure 6 The adsorption module 3 is arranged in the air flow channel 11, as shown in FIG. Figure 5 As shown, it is configured to purify the gas flowing through the gas flow channel 11. The regeneration module 4 is configured to regenerate the adsorption module 3.

[0038] The air purification module provided in the embodiment of the present application includes a frame 1, a frame door 2, an adsorption module 3 and a regeneration module 4. The frame 1 is an installation carrier for the frame door 2 and the adsorption module 3. The adsorption module 3 is used to adsorb pollutants in the gas to achieve the function of purifying the air. The regeneration module 4 is used to regenerate the adsorption module 3 to achieve the regeneration of the adsorbent and avoid the replacement of the adsorption module 3. The frame door 2 is used to realize the opening and closing of the airflow channel 11 in the frame 1, so that the frame 1 has the function of supporting the adsorption module 3 and circulating air, and also has the function of creating a relatively independent enclosed regeneration space. When the air needs to be purified, the frame door 2 moves to the open position to open the airflow channel 11. Figure 2 , Figure 4 and Figure 6 As shown, the air in the space to be purified can enter the airflow channel 11, be purified by the adsorption module 3 in the airflow channel 11, and then flow out. When the adsorption module 3 needs to be regenerated, the frame door 2 moves to the closed position to close the airflow channel 11, as shown in FIG. Figure 1 , Figure 3 As shown, a closed regeneration space is formed in the frame 1.

[0039] Compared with the purification air duct of the air treatment equipment, the enclosed regeneration space in the frame 1 is much smaller. Therefore, the energy generated by the regeneration module 4 in the air flow channel 11 can only regenerate the adsorption module 3 in the enclosed regeneration space, and cannot diffuse to the external purification air duct, thereby effectively improving the energy density used for the regeneration of the adsorption module 3, and thus facilitating the rapid regeneration of the adsorption module 3.

[0040] Moreover, compared with the disc adsorption regeneration scheme, the air purification module of this scheme does not need to set up dedicated purification air ducts and regeneration air ducts. The purification process and the regeneration process are both carried out in the air flow channel 11 of the frame 1, so it occupies a small space and can be directly installed in the purification air duct (also called the main air duct) of the air treatment equipment. It can be used in home environments and overcomes the problem of poor applicability of the turntable regeneration scheme to scenarios with strict air volume requirements.

[0041] In some exemplary embodiments, the adsorption module 3 includes an air-permeable substrate and an adsorption catalytic material supported on the substrate. The substrate may be, but is not limited to, an insulating honeycomb structure substrate.

[0042] Wherein: the adsorption catalytic material may include but is not limited to at least one of the following: molecular sieve, activated carbon, silica gel, alumina, zirconium oxide, titanium oxide, etc.

[0043] The adsorption catalytic material may also include an active metal. The active metal may be selected from any one or more of manganese, copper, cerium, titanium, iron, cobalt, nickel, silver, platinum, and palladium. The mass of the active metal may account for 1% to 15% of the total mass of the adsorption catalytic material, such as 1%, 3%, 5%, 8%, 10%, 12%, 15%, etc. Of course, the percentage of the mass of the active metal to the total mass of the adsorption catalytic material is not limited to the above range, and may also be adjusted to less than 1% or greater than 15% as needed.

[0044] The adsorption catalytic material can be loaded with active metals by impregnation, sol-gel or vapor deposition. The powder of the adsorption catalytic material can then be loaded on an insulating honeycomb structure substrate by spraying or impregnation, and the loading amount can be, but is not limited to, 0.1g-0.6g (adsorption catalytic material) / g (substrate), that is, 0.1g to 0.6g of adsorption catalytic material is loaded on each gram of substrate. In other words, the mass ratio of the adsorption catalytic material to the substrate is between 1:10 and 6:10.

[0045] In this way, the adsorption module 3 can have a better adsorption purification effect, and the adsorption catalytic material can also be efficiently regenerated under the treatment of the regeneration module 4, and the substrate is made of insulating material, which is relatively safe.

[0046] In some exemplary embodiments, the frame door 2 includes a first shutter assembly 21 and a second shutter assembly 22. Figure 4 and Figure 6 As shown. The airflow channel 11 has a first vent and a second vent that are arranged opposite to each other. The first louver assembly 21 is rotatably arranged at the first vent, and is arranged to control the opening and closing of the first vent. The second louver assembly 22 is rotatably arranged at the second vent, and is arranged to control the opening and closing of the second vent. The number of louvers of the first louver assembly 21 is equal to the number of louvers of the second louver assembly 22 and corresponds one to one.

[0047] When the first louver assembly 21 closes the first vent and the second louver assembly 22 closes the second vent, the frame door 2 moves to the closed position to close the airflow channel 11. Figure 1 , Figure 3 shown.

[0048] When the first shutter assembly 21 opens the first vent and the second shutter assembly 22 opens the second vent, the frame door 2 moves to the open position to open the air flow channel 11. Figure 2 , Figure 4 and Figure 6 shown.

[0049] The frame door 2 adopts a structure of two groups of shutter assemblies, that is, the frame door 2 adopts a shutter structure (which can be called a shutter frame door), which can not only realize the closing and opening of the air flow channel 11, but also has the advantage of occupying a small space, which is conducive to further reducing the installation space required for the air purification module. The shutter assembly has a simple structure and a relatively mature driving method, which is easy to promote.

[0050] Of course, the frame door 2 is not limited to the structural form of shutters, and other structural forms can also be adopted, such as including two single doors, or including two double doors, or including two folding doors, etc., which are not listed one by one here.

[0051] In some exemplary embodiments, the regeneration module 4 is disposed in the first louver assembly 21 and / or the second louver assembly 22. When the frame door 2 moves to the closed position, the regeneration module 4 is at least partially located in the air flow channel 11 and faces the adsorption module 3, so that the regeneration module 4 can regenerate the adsorption module 3.

[0052] In other words, the regeneration module 4 is arranged on the frame door 2, such as Fig. 9 As shown. Compared with the solution of setting the regeneration module 4 on the frame 1 or other positions, the present solution sets the regeneration module 4 on the frame door 2, so that the position of the regeneration module 4 can change with the opening and closing of the frame door 2. In this way, on the one hand, when the frame door 2 closes the airflow channel 11, the regeneration module 4 can face the adsorption module 3, and then efficiently regenerate the adsorption module 3; on the other hand, when the frame door 2 opens the airflow channel 11, the regeneration module 4 can also release energy to the air flowing through the airflow channel 11 when working, so it can also purify the air flowing through the airflow channel 11, which is beneficial to improve the purification efficiency of the air purification module.

[0053] Among them, when the first louver assembly 21 and the second louver assembly 22 are both provided with the regeneration module 4, both sides of the adsorption module 3 can be regenerated by the regeneration module 4, which is beneficial to further improve the regeneration efficiency.

[0054] The regeneration module 4 may be arranged on only a small number of louvers (such as one louver) of the first louver assembly 21 and a small number of louvers (such as one louver) of the second louver assembly 22. Since the enclosed regeneration space is small, the active substances released by the small number of regeneration modules 4 can quickly fill the entire enclosed regeneration space, thereby meeting the demand for rapid regeneration of the adsorption module 3. This is conducive to reducing costs, and the small number of regeneration modules 4 is also convenient for wiring.

[0055] In some exemplary embodiments, when the frame door 2 moves to the closed position, the distance between the regeneration module 4 and the adsorption module 3 is in the range of 1 mm to 5 mm, such as 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc. This is conducive to ensuring the regeneration treatment effect of the regeneration module 4 on the adsorption module 3.

[0056] Of course, the distance between the regeneration module 4 and the adsorption module 3 is not limited to the above range and can be adjusted to be greater than 5 mm or less than 1 mm as needed.

[0057] In some exemplary embodiments, the first louver assembly 21 and the second louver assembly 22 each include a plurality of louvers, at least one of which is provided with a mounting slot 2311. Fig. 9 As shown, the mounting groove 2311 is configured to accommodate the regeneration module 4 .

[0058] The installation slot 2311 is provided on the louver, so that the regeneration module 4 can be at least partially provided in the installation slot 2311, which is beneficial to avoid the regeneration module 4 being too protruding and causing excessive wind resistance, thereby improving the purification efficiency of the air purification module. In addition, this is also beneficial to reducing the volume of the air purification module.

[0059] In some embodiments, the thickness of the louver is greater than or equal to 2 mm. The depth of the mounting groove 2311 is greater than or equal to 1 mm. The distance between the outer edge of the louver and the outer edge of the regeneration module 4 is greater than or equal to 2 mm. This can ensure the strength of the louver and the stability and reliability of the regeneration module 4.

[0060] In some exemplary embodiments, the first louver assembly 21 and the second louver assembly 22 each include a plurality of louvers, such as Figure 4 and Figure 6 The shutter includes a blade body 231 and a rotating shaft 232 connected to the blade body 231. Fig. 9 and Fig.10 As shown. The rotating shaft 232 is rotatably connected to the frame 1. Structures such as channels can be provided on the frame 1 to realize the installation and fixation of the louver and the frame 1, and to ensure that the louver can rotate between the open position and the closed position. The above-mentioned installation groove 2311 for installing the regeneration module 4 is provided on the louver body, and is provided on the side surface of the louver body facing the adsorption module 3 when the frame door 2 is in the closed position. The number of rotating shafts 232 of a louver can be two, and the two rotating shafts 232 can be provided at the same end of the louver body in the width direction, and are respectively provided at the two ends of the louver body in the length direction. The diameter of the rotating shaft 232 is not less than the thickness of the blade body 231, and is installed in cooperation with the reserved hole position in the frame 1.

[0061] The rotating shaft 232 of the first louver assembly 21 and the rotating shaft 232 of the second louver assembly 22 are controlled in linkage through the linkage mechanism 5. Figure 7 and Figure 8 This facilitates the linkage control of the first louver assembly 21 and the second louver assembly 22 through one driving member, which is beneficial to simplifying the product structure and reducing the product cost.

[0062] It can be that a group of rotating shafts 232 of the first louver assembly 21 located on the same side cooperates with the linkage mechanism 5 to achieve linkage control, while the other group of rotating shafts 232 does not cooperate with the linkage mechanism 5. A group of rotating shafts 232 of the second louver assembly 22 located on the same side cooperates with the linkage mechanism 5 to achieve linkage control, while the other group of rotating shafts 232 does not cooperate with the linkage mechanism 5. This is conducive to simplifying the linkage mechanism 5. Of course, it can also be that both groups of rotating shafts 232 of the first louver assembly 21 and the second louver assembly 22 cooperate with the linkage mechanism 5. The linkage mechanism 5 can be installed on the frame 1.

[0063] In some embodiments, Figure 7 and Figure 8 As shown, the linkage mechanism 5 includes a rack 53, a plurality of first gears 51 and a plurality of second gears 52, and the first rack 53 has a first tooth portion and a second tooth portion that are arranged opposite to each other. The plurality of first gears 51 are connected one by one with the rotating shaft 232 of the first louver assembly 21 (which can be one set of rotating shafts 232 or two sets of rotating shafts 232), and the plurality of second gears 52 are connected one by one with the rotating shaft 232 of the second louver assembly 22 (which can be one set of rotating shafts 232 or two sets of rotating shafts 232), and the plurality of first gears 51 are meshed with the first tooth portion, and the plurality of second gears 52 are meshed with the second tooth portion; the rack 53 is arranged to be connected to the driving member, and moves along the extension direction of the rack 53 under the drive of the driving member.

[0064] In some exemplary embodiments, the regeneration module 4 includes at least one of the following: a plasma generation module and an ultraviolet generation module. The plasma generation module can be operated to generate plasma, ozone, hydroxyl radicals and other substances, and the adsorbed pollutants are oxidized under the action of plasma and active species to achieve the regeneration of the adsorption catalytic material. The ultraviolet generation module can regenerate the adsorption module 3 through photocatalytic regeneration. Both can be used to regenerate the adsorption module 3, and they do not conflict with each other. One can be set or the other can coexist.

[0065] The frame 1 is an insulating oxidation-resistant part, and the frame door 2 is an insulating fire-resistant part. In other words, the frame door 2 is made of a material with good insulation performance and certain fire resistance, such as ceramic, corundum, quartz, plastic, Teflon, etc. This helps to avoid safety risks caused by the conduction or fire of the frame door 2 during the regeneration process. The frame 1 is an insulating oxidation-resistant part, such as plastic, Teflon, ceramic, etc., which is also conducive to improving the safety of the regeneration process and extending the service life of the frame 1.

[0066] In some exemplary embodiments, the regeneration module 4 includes a plasma generation module. The plasma generation module includes a dielectric barrier discharge module. The dielectric barrier discharge module includes an insulating dielectric layer 43 and a discharge electrode 41 and a counter electrode 42 respectively disposed on both sides of the insulating dielectric layer 43. Fig.11 and Fig.12 The discharge electrode 41 is configured to discharge in the airflow channel 11 (to generate plasma, ozone, hydroxyl radicals and other substances) when the frame door 2 closes the airflow channel 11 to regenerate the adsorption module 3. The dielectric barrier discharge module can be attached to the mounting groove 2311 of the shutter arrangement, as shown in FIG. Fig. 9 shown.

[0067] The insulating dielectric layer 43 may be made of a material with a dielectric constant greater than 1, such as ceramic, corundum, quartz, mica, etc. The size is not limited, and the thickness may be within the range of, but not limited to, 0.2 mm-2 mm.

[0068] The discharge electrode 41 and the counter electrode 42 may be asymmetric metal electrodes printed on the insulating dielectric layer 43 , and the material may be, for example, a metal material with good conductivity such as copper, silver, titanium, etc.

[0069] In some embodiments, the discharge electrode 41 includes at least one strip electrode, such as Fig.11 As shown. The counter electrode 42 is a surface electrode, such as Fig.12 The area of ​​the counter electrode 42 is larger than the area of ​​the discharge electrode 41.

[0070] The strip electrodes may be in the shape of elongated strips, fishbone shapes, rings, etc., and may be arranged individually or in combination. The counter electrode 42 may be a large-area sheet-shaped printed electrode. The ends of the discharge electrode 41 and the counter electrode 42 may be provided with wiring terminals, which may be semicircular, circular, or other shapes.

[0071] The surface of the counter electrode 42 facing away from the insulating medium layer 43 is covered with an insulating layer (such as insulating paint, not shown in the figure) to limit the discharge of the counter electrode 42 to the air. In this way, it can be ensured that the discharge phenomenon occurs at the discharge electrode 41, but not at the counter electrode 42, so as to ensure that the active substances generated by the discharge are sprayed toward the adsorption module 3, thereby efficiently regenerating the adsorption module 3.

[0072] The dielectric barrier discharge module can be driven by a high voltage AC power supply (not shown in the figure). The driving voltage of the dielectric barrier discharge module can be in the range of, but not limited to, 6kV to 8kV (such as 6kV, 6.5kV, 7kV, 7.5kV, 8kV, etc.), the frequency of the driving voltage can be in the range of, but not limited to, 20kHz to 30kHz (such as 20kHz, 22kHz, 25kHz, 28kHz, 30kHz, etc.), and the input power of the dielectric barrier discharge module can be in the range of, but not limited to, 4W to 6W (such as 4W, 5W, 6W, etc.).

[0073] The embodiment of the present application also provides an air treatment device (not shown in the figure), including an air purification module as in any one of the above embodiments, and thus has all the above-mentioned beneficial effects, which will not be repeated here.

[0074] Among them, the types of air treatment equipment may include but are not limited to: air purifiers, air conditioners, humidifiers, dehumidifiers, etc.

[0075] In some exemplary embodiments, the air treatment device may include a housing, and a purification air duct (or main air duct) may be provided in the housing. The air purification module may be installed in the purification air duct, or at the air inlet of the purification air duct, or at the air outlet of the purification air duct. When the air flow channel 11 of the air purification module is opened, it is connected to the purification air duct to purify the gas flowing through the purification air duct.

[0076] In some exemplary embodiments, the number of the air purification module may be one or more. The multiple air purification modules may be arranged in an array to further improve the purification efficiency.

[0077] In some exemplary embodiments, the air treatment device further includes a circulation fan, which is configured to drive the air in the space to be purified to flow through the purification air duct. When the air treatment device needs to purify the air, the circulation fan is started, and the air purification module is also started to purify the gas flowing through the purification air duct. When the purification is completed, the circulation fan is turned off and the air purification module is also turned off. When the regeneration module 4 regenerates the adsorption module 3, the regeneration module 4 is started and the circulation fan is turned off. Of course, the circulation fan can also be integrated in the air purification module.

[0078] In some exemplary embodiments, the air treatment device further includes a detection module, which is configured to detect air quality information of the space to be purified and send it to the control device. The control device can obtain the air quality information of the space to be purified through the detection module to reasonably control the circulation fan and the air purification module. Of course, the detection module can also be integrated in the air purification module.

[0079] The detection module may include but is not limited to a TVOC (Total Volatile Organic Compounds) concentration detector for detecting the TVOC concentration of the space to be purified. The detection module may also include a microbial concentration detector. The detection module may also include an odor concentration detector.

[0080] In some exemplary embodiments, the air treatment device further includes a driving member (not shown in the figure), which is connected to the linkage mechanism 5 of the air purification module and is configured to drive the linkage mechanism 5 to drive the frame door 2 to move so that the frame door 2 moves to an open position or a closed position. The driving member may be, but is not limited to, a driving motor. Of course, the driving member may also be integrated in the air purification module.

[0081] In some exemplary embodiments, the air treatment equipment also includes a high-voltage AC power supply (not shown in the figure), which is configured to be electrically connected to the dielectric barrier discharge module of the air purification module. The discharge electrode 41 of the dielectric barrier discharge module is connected to the high-voltage end of the high-voltage AC power supply, and the counter electrode 42 is connected to the low-voltage end or the ground terminal of the high-voltage AC power supply. Of course, the high-voltage AC power supply can be integrated in the air purification module.

[0082] The present application also provides a control method for the air treatment equipment in the above embodiment. Fig.13 As shown, the control method includes:

[0083] Step S202: determining a target working mode, where the target working mode includes a purification mode and a regeneration mode;

[0084] Step S204: Control the air purification module according to the determined target working mode; wherein, in the purification mode, the control frame door 2 is moved to an open position to open the air flow channel 11; in the regeneration mode, the control frame door 2 is moved to a closed position to close the air flow channel 11, and the regeneration module 4 is controlled to operate to regenerate the adsorption module 3.

[0085] The control method provided in the embodiment of the present application can control the air purification module according to the determined target working mode after determining the target working mode. When the determined target working mode is the purification mode, the frame door 2 of the air purification module moves to the open position, and the air flow channel 11 of the frame 1 is connected, and the air in the space to be purified can enter the air flow channel 11, flow through the adsorption module 3, and be purified by the adsorption module 3. When the determined target working mode is the regeneration mode, the frame door 2 of the air purification module moves to the closed position, and the air flow channel 11 of the frame 1 is closed to form a closed regeneration space. The regeneration module 4 is operated to regenerate the adsorption module 3, so that the adsorption module 3 is regenerated.

[0086] Controlling the operation of the regeneration module 4 refers to: when the regeneration module 4 is in a closed state, starting the operation of the regeneration module 4; and when the regeneration module 4 is in an operating state, maintaining the operating state.

[0087] Of course, in order to improve the purification efficiency, in the purification mode, the circulation fan is also controlled to run. In the regeneration mode, the circulation fan is controlled to be turned off to avoid wasting electric energy and ensure the regeneration effect.

[0088] In some exemplary embodiments, the control method further includes:

[0089] Based on the purification instruction received from the external input, determining that the target working mode is the purification mode;

[0090] Based on the regeneration command received from the external input, the target operation mode is determined to be the regeneration mode.

[0091] When receiving a purification command from an external input, such as when a user inputs a purification command through a remote control, a control panel, or a smart terminal (such as a mobile phone, a computer, or an APP on a wristband), the target working mode can be determined to be the purification mode. This solution can meet the personalized needs of users, allowing users to purify the space to be purified at any time.

[0092] When a regeneration command is received from an external input, such as when a user inputs a regeneration command through a remote control, a control panel, or an intelligent terminal (such as a mobile phone, a computer, or an APP of a wristband), the target working mode can be determined to be the regeneration mode. This solution can meet the personalized needs of the user, so that the user can regenerate the adsorption module 3 at any time.

[0093] In some exemplary embodiments, the control method further includes: obtaining air quality information of a space to be purified. The space to be purified may be, but is not limited to, an indoor space.

[0094] Determine the target work model, including:

[0095] Based on the air quality information of the space to be purified meeting the set purification conditions, the target working mode is determined to be the purification mode;

[0096] Based on satisfying the set regeneration condition, the target operation mode is determined to be the regeneration mode.

[0097] When the air quality information of the space to be purified meets the set purification conditions, it indicates that the space to be purified needs purification, so the target working mode can be determined as the purification mode. This solution can realize automatic purification of the space to be purified without user monitoring, which is conducive to improving the user experience.

[0098] When the set regeneration condition is met, it indicates that the adsorption module 3 has basically reached adsorption saturation and needs to be regenerated, so the target working mode can be determined to be the regeneration mode. This solution can realize the automatic regeneration of the adsorption module 3 without the need for user monitoring, which is conducive to improving the user experience.

[0099] In some exemplary embodiments, the set purification condition includes a first set purification condition and a second set purification condition, and the purification mode includes a first purification mode and a second purification mode;

[0100] Based on the air quality information of the space to be purified meeting the set purification conditions, the air purification module is controlled to enter the purification mode, including:

[0101] Based on the air quality information of the space to be purified meeting the first set purification condition, the air purification module is controlled to enter the first purification mode; in the first purification mode, the frame door 2 is controlled to move to the open position to open the air flow channel 11, so that the adsorption module 3 purifies the air in the space to be purified;

[0102] Based on the air quality information of the space to be purified meeting the second set purification condition, the air purification module is controlled to enter the second purification mode; in the second purification mode, the control frame door 2 is moved to the open position to open the air flow channel 11, and the regeneration module 4 is started, so that the adsorption module 3 and the regeneration module 4 jointly purify the air in the space to be purified.

[0103] In some embodiments, the air quality information includes the concentration C of total volatile organic compounds (i.e., TVOC concentration), the first set purification condition includes: Cs<C<10Cs, and the second set purification condition includes: C≥10Cs. Cs represents a set concentration threshold, i.e., a set safety concentration threshold. Cs may be the maximum concentration value allowed by the national standard for indoor spaces.

[0104] When the air quality information of the space to be purified meets the first set purification condition, it indicates that the air quality of the space to be purified is poor and needs to be purified, but the purification requirement can be met by only using the adsorption module 3. Therefore, in the first purification mode, only the adsorption module 3 is used to purify the air in the space to be purified.

[0105] When the air quality information of the space to be purified meets the second set purification condition, it indicates that the air quality of the space to be purified is very poor and needs to be purified, but the adsorption module 3 alone cannot meet the purification requirements. Therefore, in the second purification mode, the adsorption module 3 and the regeneration module 4 are used to purify the air in the space to be purified. The regeneration module 4 can generate plasma, ozone, hydroxyl radicals and other substances to increase the removal capacity of the adsorption module 3 for pollutants, thereby improving the purification efficiency.

[0106] In some exemplary embodiments, the control method further includes: controlling the air purification module to exit the purification mode based on the air quality information of the to-be-purified space satisfying a set purification end condition. The set purification end condition includes: C≤Cs.

[0107] When exiting the purification mode, the control frame door 2 moves to the closed position to close the air flow channel 11 and turn off the circulation fan.

[0108] In some exemplary embodiments, setting the regeneration conditions includes:

[0109] Based on the air purification module running in the first purification mode: the air purification module has completed running in the first purification mode; and during the operation of the first purification mode, the purification efficiency of the first purification mode running for a set time η<first initial purification efficiency η1×a, the first initial purification efficiency η1=the set first initial purification efficiency or the purification efficiency of the first purification mode running for a set time during the first use, where a is a coefficient, 0<a<1;

[0110] Based on the air purification module running in the second purification mode: the air purification module has completed operation in the second purification mode; or, the air purification module has completed operation in the second purification mode; and during the operation of the second purification mode, the purification efficiency of the second purification mode for a set period of time η<the second initial purification efficiency η2×b, the second initial purification efficiency η2=the set first initial purification efficiency or the purification efficiency of the second purification mode for a set period of time during the first use, wherein b is a coefficient, 0<b<1.

[0111] In some examples, a≤0.5, b≤0.5. Of course, the value range of a and b is not limited to this range, and can also be adjusted to be greater than 0.5 as needed. The set time length can be, for example, 30 minutes, and of course the set time length can also be reasonably adjusted to other values ​​as needed.

[0112] Therefore, the regeneration mode is performed after the purification mode is completed to give priority to the purification needs of the space to be purified.

[0113] Among them, for the first purification mode, whether the adsorption module 3 needs to be regenerated is determined based on whether the purification efficiency is severely attenuated during the operation of the first purification mode. When the purification efficiency η of the first purification mode for a set period of time is less than the first initial purification efficiency η1×a, it indicates that the purification efficiency of the adsorption module 3 is severely attenuated and needs to be regenerated. The first initial purification efficiency η1 can be the first initial purification efficiency, that is, the purification efficiency obtained by the test before leaving the factory, which is pre-stored in the system. The first initial purification efficiency η1 can also be the purification efficiency of the first purification mode for a set period of time during the first use of the first purification mode, that is, the purification efficiency of the first purification mode for a set period of time when the air purification module runs for the first time after leaving the factory, which is recorded and stored in the system. Of course, when the purification efficiency η of the first purification mode for a set period of time ≥ the first initial purification efficiency η1×a, if a regeneration command input by the user is received, the regeneration mode is also entered when the first purification mode is completed.

[0114] For the second purification mode, regeneration can be performed after each operation is completed, because the air quality of the space to be purified is generally very poor when the second purification mode is running, which easily causes the adsorption module 3 to adsorb more pollutants, so regeneration can be performed every time after the second purification mode is completed. This is conducive to simplifying the electronic control program. Of course, it is also possible to judge whether the adsorption module 3 needs to be regenerated according to whether the purification efficiency is severely attenuated during the operation of the second purification mode. When the purification efficiency η of the second purification mode for the set time is less than the second initial purification efficiency η2×b, it indicates that the purification efficiency of the adsorption module 3 is severely attenuated and needs to be regenerated. The second initial purification efficiency η2 can be the second initial purification efficiency, that is, the purification efficiency obtained by the test before leaving the factory, which is pre-stored in the system. The second initial purification efficiency η2 can also be the purification efficiency of the second purification mode during the first use of the second purification mode, that is, the purification efficiency of the second purification mode for the second time after leaving the factory, which is recorded and stored in the system. Of course, when the purification efficiency η of the first purification mode for the set time is greater than or equal to the second initial purification efficiency η2×b, if the regeneration instruction input by the user is received, the regeneration mode is also entered when the second purification mode is completed.

[0115] Of course, the regeneration condition is not limited to the above conditions, for example, it may also be: the accumulated purification time of the air purification module reaches the set time.

[0116] In some exemplary embodiments, the control method further includes: setting a regeneration time based on the regeneration mode operation, controlling the air purification module to exit the regeneration mode, and shutting down the regeneration module 4 when exiting the regeneration mode. The set regeneration time may be, but is not limited to, 30 minutes.

[0117] An embodiment is described below.

[0118] A shutter-type air purification module, wherein the structural frame 1 has a length of 140 mm, a width of 65 mm, a height of 18 mm, a wall thickness of 2.5 mm, and is made of ABS plastic with a fire resistance grade of V0. Six groups of shutter assemblies are fixed on the frame 1 structure, and the material is the same as the frame 1 structure. Each group of shutter assemblies includes a first shutter assembly 21 and a second shutter assembly 22. The blade body 231 of each group of shutter assemblies has a size of 22.5 mm × 60 mm × 2 mm, one side of which is provided with a groove of 15 mm × 55 mm × 1 mm, and a plasma generating module in the form of a dielectric barrier discharge of 14.5 mm × 54.5 mm × 1 mm is provided inside the groove, and the upper portion is printed with an electrode in the form of a printed electrode. Fig.11 and Fig.12As shown. The six groups of shutter assemblies are linked to open and close through six groups of gears and a group of racks 53. A 135mm×60mm×10mm ceramic honeycomb is arranged inside the frame 1, and 10g of MnCe-Beta type adsorption catalytic material (MnCe ratio 2:1, total loading amount is 20%, Beta type molecular sieve is H type, silicon aluminum ratio is 300) is loaded on the ceramic honeycomb. When the frame door 2 is closed, the distance between it and the honeycomb ceramic is 3mm.

[0119] The method for purifying pollutants using this embodiment is as follows: Fig.14 As shown: when the indoor household TVOC concentration exceeds the maximum concentration Cs allowed by the national standard, or when the user manually starts the purification function, the shutter-type frame door 2 of the air purification module is opened and kept open, and the circulating fan is started at the same time. The gas containing pollutants flows through the adsorption module 3 and is adsorbed, and clean air is output until the indoor TVOC concentration drops to the value specified by the national standard, and finally the TVOC inside the space is purified.

[0120] When the adsorption catalytic material reaches the cycle life (i.e. η<0.5η0, where: when the current purification mode is the first purification mode, η0 is η1; when the current purification mode is the second purification mode, η0 is η2), or the user manually starts the regeneration function (i.e. receives the input regeneration instruction), the shutter frame door 2 of the air purification module is closed and remains closed, and the plasma generation module is started at the same time, maintaining the input voltage of 12V and the input power of 5W. At this time, the output voltage should be 6.5kV, the frequency is 25kHz, and the output power is 2.3W. At this time, the plasma generation module generates plasma and highly active species such as ozone, hydroxyl radicals, etc. The adsorbed pollutants are oxidized under the action of plasma and active species to achieve the regeneration of the adsorption catalyst. The plasma generation module is turned off after running for 30 minutes, and the regeneration is completed.

[0121] For high concentrations of pollutants, the plasma generation module can be turned on in the adsorption state with the shutter-type frame door 2 opened to generate plasma and active species to increase the removal capacity of the adsorption catalytic material. Multiple air purification modules can also be connected in parallel to improve the removal effect.
