Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air purification technology, specifically to an air purification device, air handling equipment, and its control method and control device. Background Technology

[0002] Currently, air purification devices are fixed inside air ducts, allowing air to flow through and be purified. However, when the airflow direction changes, the active substances produced by the air purification device have difficulty making sufficient contact with germs in the incoming air, affecting the air purification effect. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide an air purification device in which the plasma generating module is configured as a movable structure, so that the extension direction of the plasma generating area can be adjusted with the direction of the incoming wind, thereby facilitating that the active substances generated by the plasma generating module under different wind directions can fully contact the germs in the airflow, thus improving the air purification effect.

[0004] This application provides an air purification device, including: a mounting frame with an air inlet and an air outlet; a plasma generating module with a plasma generating area extending from the air inlet to the air outlet and communicating with both the air inlet and the air outlet; the plasma generating module is mounted on the mounting frame and at least partially movable relative to the mounting frame to adjust the extension direction of the plasma generating area, so that the extension direction of the plasma generating area can be adapted to the incoming airflow direction at the air inlet.

[0005] The air purification device provided in this application embodiment has a plasma generating module movably mounted on a mounting frame. Therefore, the plasma generating module is not a fixed structure but a movable structure, allowing it to move relative to the mounting frame. This enables the extension direction of the plasma generating area to be adjusted as needed. Thus, when the direction of the incoming airflow changes, the extension direction of the plasma generating area can be adjusted accordingly to adapt to the incoming airflow direction. This ensures that the incoming airflow direction always matches (e.g., is consistent with) the extension direction of the plasma generating area, minimizing dead zones within the plasma generating area. This helps ensure that the active substances generated by the plasma generating module can fully contact harmful substances such as bacteria in the incoming air under different airflow directions, thereby guaranteeing air purification efficiency.

Detailed Implementation

[0012] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0013] like Figures 1 to 6 As shown in the figure, this application provides an air purification device, including: a mounting bracket 2 and a plasma generating module 1.

[0014] Mounting bracket 2 can be installed on the housing of the air handling equipment. Mounting bracket 2 is provided with an air inlet and an air outlet. Plasma generating module 1 is provided with a plasma generating zone 14. Discharge phenomena can occur in plasma generating zone 14, generating active substances such as plasma. These active substances can kill germs, pollutants and other substances in the air, thereby playing a purification role.

[0015] The plasma generation zone 14 is configured to extend from the air inlet to the air outlet and is connected to both the air inlet and the air outlet. In this way, the airflow entering from the air inlet can flow through the plasma generation zone 14 to the air outlet, allowing germs, pollutants, and other substances in the airflow to come into contact with the active substances in the plasma generation zone 14 and be purified.

[0016] The plasma generating module 1 is mounted on the mounting frame 2 and is at least partially movable relative to the mounting frame 2 to adjust the extension direction of the plasma generating area 14 so that the extension direction of the plasma generating area 14 can be adapted to the incoming airflow direction at the air inlet.

[0017] In related technologies, the plasma generating zone 14 is a fixed structure, therefore its extension direction is fixed. When the incoming airflow direction at the air inlet is consistent with the normal direction of the air inlet, the extension direction of the plasma generating zone 14 is also consistent with the incoming airflow direction, allowing harmful substances in the airflow to fully contact the active substances within the plasma generating zone 14, such as... Figure 4 As shown. However, when the incoming airflow direction at the air inlet changes, the extension direction of the plasma generation zone 14 is inconsistent with the incoming airflow direction. This results in very little or no airflow in areas of the plasma generation zone 14 that deviate from the incoming airflow direction, leading to dead zones (such as...) within the plasma generation zone 14. Figure 5If the gray triangle area is in the dead zone, the active substances in the dead zone cannot fully contact the harmful substances in the air, resulting in a reduction in the purification efficiency of the air purifier.

[0018] The air purification device provided in this application embodiment has the plasma generating module 1 movably mounted on the mounting bracket 2. Therefore, the plasma generating module 1 is not a fixed structure, but a movable structure, allowing it to move relative to the mounting bracket 2. This enables the extension direction of the plasma generating area 14 to be adjusted as needed. Thus, when the incoming airflow direction changes through the air purification device, the extension direction of the plasma generating area 14 can be adjusted accordingly to adapt to the incoming airflow direction, ensuring that the incoming airflow direction always matches (e.g., is consistent with) the extension direction of the plasma generating area 14. Figure 6 As shown, this design minimizes dead zones within the plasma generation zone 14, ensuring that the active substances generated by the plasma generation module 1 under different incoming airflow directions can fully contact harmful substances such as bacteria in the incoming air, thereby guaranteeing air purification efficiency.

[0019] In some exemplary embodiments, the plasma generating region 14 includes at least one generating region group, which includes a plurality of sub-generating regions 14 arranged along the extending direction of the plasma generating region 14.

[0020] This allows for an increase in the length of the plasma generating region 14, providing the plasma generating module 1 with a larger plasma generation space and improving air purification efficiency. Furthermore, the extension direction of the plasma generating region 14 can be adjusted by changing the relative positions of adjacent sub-generating regions 14 within the generating region group.

[0021] The number of generation area groups can be one or more. Multiple generation area groups can be set up side by side, thus forming an array of sub-generation areas 14, such as... Figures 1 to 6 As shown, the plasma generating module 1 can be in the form of a matrix grid structure, which has a large plasma generation space and is conducive to improving air purification efficiency.

[0022] exist Figures 1 to 6 In the diagram, the sub-generator region 14 is represented by a solid box between the first electrode 13 and the second electrode 12, but there is actually no solid box structure.

[0023] In some exemplary embodiments, such as Figures 1 to 6As shown, the plasma generating module 1 includes multiple discharge components arranged along the extension direction of the plasma generating region 14. Each discharge component includes a first electrode 13 and a second electrode 12 alternately arranged along a first direction. Both the first electrode 13 and the second electrode 12 are tubular electrodes extending along a second direction. The space between adjacent first electrodes 13 and second electrodes 12 forms a sub-generating region 14. The discharge components are configured to discharge and generate plasma in the sub-generating region 14. Thus, the plasma generating region 14 has a large flow cross-sectional area, and the plasma generating module 1 has a small volume.

[0024] exist Figures 4 to 6 In the first direction, the direction is the line connecting the centers of the tubular electrodes in the discharge assembly, and the extension direction of the plasma generation region 14 is the line connecting the centers of the tubular electrodes in the same row of the discharge assembly.

[0025] When the discharge assembly includes a first electrode 13 and a second electrode 12, the discharge assembly has a sub-generating region 14, and the plasma generating region 14 can have a group of generating regions. In this way, the plasma generating region 14 has a simple structure and low cost.

[0026] When the number of electrodes in the discharge assembly exceeds two, one discharge assembly has multiple sub-generating regions 14, and the plasma generating region 14 can have multiple generating region groups. In this way, the plasma generating module 1 has a matrix grid structure with a large plasma space, which is beneficial for improving air purification efficiency. In one example, such as... Figures 1 to 6 As shown, each discharge assembly includes two first electrodes 13 and one second electrode 12. The discharge assemblies are configured in two groups.

[0027] At least some of the discharge components can move relative to the mounting frame 2 to adjust the arrangement direction of the multiple discharge components, thereby changing the extension direction of the plasma generation region 14.

[0028] It is permissible for only some of the discharge components to be movable relative to the mounting bracket 2. For example, the discharge component closest to the air inlet is fixed, while the discharge components downstream of this component can reciprocate along the first direction (in contrast). Figure 4 and Figure 6 It can be seen that the arrangement direction of multiple discharge components can be adjusted.

[0029] Alternatively, all discharge components can move relative to the mounting frame 2, allowing for flexible adjustment of the arrangement direction of multiple discharge components.

[0030] In other embodiments, the first electrode 13 and the second electrode 12 are not limited to tubular electrodes, and the number of discharge components is not limited to multiple. For example, the first electrode 13 and / or the second electrode 12 are plate electrodes, and the extension direction of the plasma generation region 14 is adjusted by adjusting the tilt direction of the plate electrodes.

[0031] In some exemplary embodiments, such as Figure 1 and Figure 2 As shown, the discharge assembly also includes a barrier dielectric layer 11 that separates the first electrode 13 and the second electrode 12, and at least one of the first electrode 13 and the second electrode 12 is covered by the barrier dielectric layer 11. In this way, the discharge assembly can generate plasma based on dielectric barrier discharge technology, which helps to avoid breakdown and sparking, and improves the stability and safety of the air purification device.

[0032] In some embodiments, the air purification device may further include a power supply module, which may include a high-voltage power supply. If the first electrode 13 is a high-voltage electrode and the second electrode 12 is a ground electrode or a low-voltage electrode, then the first electrode 13 is connected to the high-voltage terminal of the power supply module, and the second electrode 12 is connected to the ground terminal or the low-voltage terminal of the power supply module. Alternatively, if the first electrode 13 is a ground electrode or a low-voltage electrode, and the second electrode 12 is a high-voltage electrode, then the second electrode 12 is connected to the high-voltage terminal of the power supply module, and the first electrode 13 is connected to the ground terminal or the low-voltage terminal of the power supply module. Alternatively, if both the first electrode 13 and the second electrode 12 are high-voltage electrodes, then the power supply module may include two high-voltage transformers, with the first electrode 13 and the second electrode 12 respectively connected to the high-voltage terminals of the two high-voltage transformers. However, the output voltages of the two high-voltage transformers have a phase difference, so that the applied voltages of the first electrode 13 and the second electrode 12 have a phase difference. At least the high-voltage electrode is covered by a barrier dielectric layer 11 for added safety.

[0033] In some embodiments, the barrier medium layer 11 is a porous alumina ceramic layer.

[0034] Compared to barrier media such as glass and ordinary ceramics, alumina ceramics have a greater number of shallow wells on their surface, providing seed electrons for discharge. Furthermore, porous alumina prepared by chemical methods possesses a regular nanoscale porous structure, resulting in strong film-substrate bonding and more stable discharge. The generated micro-discharges help reduce the discharge breakdown voltage and improve discharge stability. Therefore, compared to barrier media such as glass and ordinary ceramics, discharge components using porous alumina ceramic layers are more likely to discharge uniformly, exhibit higher electron density and higher electron temperature, and are less affected by environmental factors (such as humidity, airflow, and temperature).

[0035] In some exemplary embodiments, the first electrode 13 may be, but is not limited to, a stainless steel electrode, and the second electrode 12 may be, but is not limited to, a tungsten-rhenium alloy electrode. The power supply module outputs a 30kHz sinusoidal alternating current to the discharge component.

[0036] The diameter of the first electrode 13 can be, but is not limited to, less than or equal to 2 mm, the diameter of the second electrode 12 can be, but is not limited to, less than or equal to 2 mm, the distance between adjacent first electrodes 13 and second electrodes 12 of the same discharge component can be, but is not limited to, less than or equal to 5 mm, the thickness of the barrier dielectric layer 11 can be, but is not limited to, less than or equal to 1 mm, and the distance between two adjacent discharge components can be, but is not limited to, greater than or equal to 5 mm.

[0037] In other words, the materials of the first electrode 13 and the second electrode 12 are not limited to the materials mentioned above. The diameter of the first electrode 13, the diameter of the second electrode 12, the spacing between adjacent first electrodes 13 and second electrodes 12, and the spacing between adjacent sets of discharge components are not limited to the ranges mentioned above. The power frequency of the power supply module is not limited to the ranges mentioned above, and can all be adjusted as needed.

[0038] In some exemplary embodiments, such as Figure 3 As shown, the mounting bracket 2 is provided with multiple first guide rail grooves 22 and multiple second guide rail grooves 23 corresponding to multiple discharge components, and the two ends of the tubular electrode are respectively limited to the corresponding first guide rail grooves 22 and second guide rail grooves 23.

[0039] In other words, the two ends of the first electrode 13 are respectively confined to the corresponding first guide groove 22 and second guide groove 23, and the two ends of the second electrode 12 are also respectively confined to the corresponding first guide groove 22 and second guide groove 23. In this way, the space between the main body of the first electrode 13 and the main body of the second electrode 12 is not affected by the mounting bracket 2, which is beneficial to reducing airflow resistance and also beneficial to making full use of the plasma generation area 14.

[0040] In some embodiments, such as Figure 3 and Figure 4 As shown, the mounting bracket 2 includes a frame body 21 and multiple guide rail assemblies disposed on the frame body 21, with the multiple guide rail assemblies corresponding to multiple discharge assemblies. The frame body 21 may be generally cuboid in shape.

[0041] The guide rail assembly includes two first guide rails 24 arranged side-by-side and spaced apart, and two second guide rails 25 arranged side-by-side and spaced apart. The gap between the two first guide rails 24 forms a first guide rail groove 22, and the gap between the two second guide rails 25 forms a second guide rail groove 23. The first electrode 13 and the second electrode 12 of the discharge assembly are both confined within the guide rail assembly.

[0042] The first guide rail 24 and the second guide rail 25 can extend along the first direction, and the first guide rail groove 22 and the second guide rail groove 23 also extend along the first direction. In this way, all electrodes of a discharge assembly can be confined on the same guide rail assembly, which facilitates the movement of the discharge assembly while maintaining a constant discharge gap.

[0043] In some embodiments, the air purification device further includes a track controller (not shown). The track controller is used to control the movement of the discharge assembly relative to the mounting bracket 2.

[0044] In some examples, the discharge assembly is fixed to a corresponding guide rail assembly. The guide rail assembly is movably connected to the frame body 21. The track controller is connected to at least a portion of the guide rail assembly and configured to drive the guide rail assembly to move relative to the frame body 21, thereby causing the corresponding discharge assembly to move relative to the mounting bracket 2.

[0045] For example, the first guide rail 24 and the second guide rail 25 are provided with multiple arc-shaped grooves. The two ends of each tubular electrode of the discharge assembly are confined within the arc-shaped grooves, so that the tubular electrodes of the discharge assembly cannot move relative to the guide rail assembly. Since the discharge assembly cannot move relative to the guide rail assembly, but the guide rail assembly can move relative to the frame body 21, the track controller can indirectly drive the discharge assembly to move relative to the mounting frame 2 by driving the guide rail assembly to move, thereby realizing the adjustment of the extension direction of the plasma generation zone 14.

[0046] In other examples, the discharge component is limited to the corresponding guide rail component by a limiting bracket. The limiting bracket is movably connected to the guide rail component, and the guide rail component is fixedly connected to the frame body 21. The track controller is connected to at least part of the limiting bracket and is configured to drive the limiting bracket to move relative to the guide rail component, so as to drive the corresponding discharge component to move relative to the mounting frame 2.

[0047] For example, the limiting bracket has multiple arc-shaped grooves, and the two ends of each tubular electrode of the discharge assembly are confined within the corresponding arc-shaped grooves, preventing the tubular electrodes of the discharge assembly from moving relative to the limiting bracket. However, the limiting bracket can move relative to the guide rail assembly. Therefore, the track controller can indirectly drive the discharge assembly to move relative to the mounting frame 2 by driving the limiting bracket, thereby adjusting the extension direction of the plasma generation zone 14. The guide rail assembly provides good guidance for the reciprocating movement of the limiting bracket.

[0048] The track controller may include a drive mechanism that drives the guide rail assembly / limiting bracket to move. The drive mechanism may be connected to the guide rail assembly / limiting bracket to drive its movement. The form of the drive mechanism is not limited; for example, it may be an electromagnetic actuator. Alternatively, the drive mechanism may include a drive component and a transmission mechanism. The drive component may be a motor, and the transmission mechanism may be, but is not limited to, a rack and pinion transmission mechanism, a lead screw transmission mechanism, etc.

[0049] In some exemplary embodiments, such as Figures 3 to 6 As shown, the air purification device also includes: a wind direction sensor 4, configured to detect the direction of the incoming airflow at the air inlet.

[0050] The wind direction sensor 4 can be installed at the air inlet of the mounting bracket 2 to accurately detect the incoming airflow direction. Alternatively, when the air purification device is installed at the air outlet of the air handling unit, the wind direction sensor 4 can also be installed at the air outlet of the air handling unit.

[0051] Some embodiments of this application also provide an air handling device, including an air purification device as described in any of the above embodiments, and thus have all the above-described beneficial effects, which will not be repeated here.

[0052] Other embodiments of this application also provide an air handling device, including: a main body and an air purification device. The main body is provided with an air duct. The air purification device includes a mounting frame 2 and a plasma generating module 1 mounted on the mounting frame 2. The mounting frame 2 is provided with an air inlet and an air outlet communicating with the air duct. The plasma generating module 1 is provided with a plasma generating area, which is configured to extend from the air inlet to the air outlet and communicate with the air inlet and the air outlet. The mounting frame 2 is movably connected to the main body and is configured to be able to move relative to the main body to adjust the extension direction of the plasma generating area, so that the extension direction of the plasma generating area can be adapted to the incoming airflow direction at the air inlet.

[0053] Compared with the aforementioned embodiments, the difference in this solution is that the plasma generating module 1 can be fixed on the mounting bracket 2, while the mounting bracket 2 is movably installed on the main body of the air handling equipment. By adjusting the mounting bracket 2, the extension direction of the plasma generating zone can be adjusted, which can also achieve the purpose of ensuring that the incoming airflow direction is always compatible with (e.g., consistent with) the extension direction of the plasma generating zone 14, so as to minimize the dead zone area in the plasma generating zone 14. This is beneficial to ensure that the active substances generated by the plasma generating module 1 under different incoming airflow directions can fully contact the bacteria and other harmful substances in the incoming air, thereby ensuring air purification efficiency.

[0054] As for the specific structure of the plasma generating module 1, it can be the same as the structure of the plasma generating module 1 in the aforementioned embodiment, and will not be described again here.

[0055] The connection structure between the mounting bracket 2 and the main body can be rotatable, allowing the mounting bracket 2 to rotate relative to the main body via a drive mechanism to adjust the extension direction of the plasma generation zone 14. The drive mechanism can include drive components such as a motor, or transmission mechanisms such as gear transmission mechanisms.

[0056] In some exemplary embodiments, the air handling equipment may be an air conditioner, an air purifier, a humidifier, a dehumidifier, etc.

[0057] In some exemplary embodiments, the air handling equipment is provided with an air duct and an air inlet and an air outlet connected to the air duct. The air purification device can be installed at the air inlet, inside the air duct, at the air outlet, or inside the air supply duct of a central air conditioning system, etc.

[0058] In some exemplary embodiments, the air handling unit is provided with an air outlet, and a rotatable air guide plate is provided at the air outlet to adjust the air delivery direction of the air outlet. An air purification device is located at the air outlet, and the air delivery direction of the air outlet is consistent with the incoming flow direction of the air inlet of the air purification device.

[0059] For air handling equipment with air guide plates, the air guide plates can adjust the air delivery direction of the air outlet. The air delivery direction determines the incoming airflow direction of the air purification device. Therefore, the extension direction of the plasma generation zone 14 of the air purification device can be controlled according to the state of the air guide plates.

[0060] This application also provides a control method for an air handling device as described in any of the above embodiments. Figure 7 As shown, the control methods include: Step S202: After entering the purification mode, obtain the air supply information of the air handling unit; Step S204: Control the air purification device according to the air supply information of the air handling equipment, so that the extension direction of the plasma generation area of ​​the plasma generation module is adapted to the incoming airflow direction at the air inlet.

[0061] In this way, when the air supply direction of the air handling equipment changes, the extension direction of the plasma generation zone 14 can be adjusted accordingly to adapt to the incoming airflow direction, so that the incoming airflow direction can always be adapted to (e.g., consistent with) the extension direction of the plasma generation zone 14, so as to minimize the dead zone area within the plasma generation zone 14. This helps to ensure that the active substances generated by the plasma generation module 1 under different incoming airflow directions can fully contact the germs and other harmful substances in the incoming air, thereby ensuring air purification efficiency.

[0062] In some exemplary embodiments, the air supply information includes the air supply mode and air supply direction. Obtaining the air supply information of the air handling unit includes: Determine the air supply mode based on the condition of the air guide plate of the air handling equipment; The air supply direction is determined based on the detection results of wind direction sensor 4.

[0063] For example, if the air guide plate is in motion, the air supply mode is the swing mode; if the air guide plate is stationary, the air supply mode is the fixed angle air supply mode.

[0064] In some exemplary embodiments, the air supply information includes the air supply mode and the air supply direction. The air supply mode includes an oscillation mode.

[0065] The air purification device is controlled based on the air supply information of the air handling equipment to adapt the extension direction of the plasma generation zone 14 of the plasma generation module 1 to the incoming airflow direction at the air inlet, including: Based on the air supply mode being swing mode, the air purification device is dynamically adjusted according to the dynamically changing air supply direction of the air handling equipment, so that the extension direction of the plasma generation zone 14 is adapted to the air supply direction of the air handling equipment.

[0066] When the air supply mode is swing mode, the air guide plate is in motion, and the air supply direction of the air outlet will change dynamically. Therefore, the extension direction of the plasma generation zone 14 also needs to change dynamically to ensure that the active substances generated by the air purification device can always be in full contact with harmful substances in the air to ensure high purification efficiency.

[0067] Among them, the track controller of the air purification device and the drive device of the air guide plate can be linked for control, so that the extension direction of the plasma generation zone 14 can be dynamically adjusted with the dynamic changes of the air guide plate.

[0068] In some embodiments, the process of dynamically adjusting the air purifier can continue until the earlier of the swing mode end time and the purification mode end time.

[0069] In some exemplary embodiments, the air supply information includes an air supply mode and an air supply direction. The air supply mode includes a fixed-angle air supply mode. The air purification device is controlled according to the air supply information of the air handling equipment to adapt the extension direction of the plasma generation zone 14 of the plasma generation module 1 to the incoming airflow direction at the air inlet, including: Based on the fixed-angle air supply mode, the air purification device is controlled according to the air supply direction of the air handling equipment, so that the extension direction of the plasma generation zone 14 is adapted to the air supply direction of the air handling equipment.

[0070] When the air supply mode is fixed angle air supply mode, the air guide plate is in a stationary state, and the air supply direction of the air outlet will not change. Therefore, the extension direction of the plasma generation zone 14 does not need to change dynamically. At this time, it is only necessary to control the air purification device according to the current air supply direction so that the extension direction of the plasma generation zone 14 is adapted to (consistent with) the current air supply direction. This ensures that the active substances generated by the air purification device can always be in full contact with harmful substances in the air, so as to ensure high purification efficiency.

[0071] Specifically, controlling the air purification device according to the air supply direction of the air handling equipment to match the extension direction of the plasma generation zone 14 with the air supply direction of the air handling equipment means: when the current extension direction of the plasma generation zone 14 matches the current air supply direction of the air handling equipment, the air purification device is kept in its current state; when the current extension direction of the plasma generation zone 14 does not match the current air supply direction of the air handling equipment, the air purification device is adjusted to match the extension direction of the plasma generation zone 14 with the current air supply direction of the air handling equipment.

[0072] Therefore, whether the air purifier will operate when the air supply mode is fixed angle air supply mode depends on whether the current air supply direction matches the current extension direction of the plasma generation zone 14.

[0073] In some embodiments, based on a fixed-angle air supply mode, the air purification device is controlled according to the air supply information of the air handling equipment to make the extension direction of the plasma generation zone 14 of the plasma generation module 1 match the incoming airflow direction at the air inlet, and further includes: The airflow direction of the air handling unit is retrieved again at set intervals. If the air supply direction of the air handling equipment changes and the change exceeds the set angle range, the air purification device is adjusted according to the air supply direction obtained again, so that the extension direction of the plasma generation zone 14 is adapted to the air supply direction obtained again, and the process returns to the step of obtaining the air supply information of the air handling equipment. If the air supply direction of the air handling unit has not changed or the change range has not exceeded the set angle range, return to the step of obtaining the air supply direction of the air handling unit again after the set interval.

[0074] The duration can be set to, but is not limited to, 5 minutes, and the angle range can be set to, but is not limited to, greater than 2°.

[0075] In fixed air supply mode, users may adjust the air supply direction periodically via remote control or other devices, or manually adjust the direction of the air guide plate, causing changes in the air supply direction. Therefore, it is necessary to monitor the air supply direction so that the extension direction of the plasma generation zone 14 can be adjusted promptly when significant changes occur. Limiting the range of changes in the air supply direction and the monitoring frequency is to prevent unstable air supply direction caused by wind influence from resulting in excessively frequent adjustments to the extension direction of the plasma generation zone 14.

[0076] In some exemplary embodiments, the control method further includes: turning off the air purifier based on the condition that the purification mode ends.

[0077] Therefore, regardless of whether it is the control process in swing mode or fixed air supply mode, the air purification device will be turned off when the conditions for ending the purification mode are met, and no further control processes will be performed.

[0078] The conditions for ending the purification mode are not limited. For example, it can be: the air purifier working for a set time (such as 2 hours), the concentration of environmental pollutants decreasing to below a set safe concentration threshold, or receiving an external command to end the purification mode (the user manually turns off the purification mode).

[0079] In one embodiment, such as Figure 8 As shown, the control method includes the following steps: Step S302: Turn on the purification function; Step S304: Determine whether the air supply mode is swing mode based on the state of the air guide plate; if yes, proceed to step S306, otherwise proceed to step S308.
