Description

Technical Field

[0001] This invention relates to the field of air purification, and in particular to a control method and apparatus for purification equipment, and purification equipment. Background Technology

[0002] As people's demands for quality of life continue to rise and air pollution becomes increasingly serious, air purification technology is gradually gaining attention.

[0003] For example, particulate matter in the air, as one of the main pollutants in indoor air, affects the health of people living indoors. Most existing air purification technologies and air purifier products only focus on the total amount of indoor particulate matter. Common existing technologies can quickly purify indoor air by detecting the total concentration of indoor particulate matter and then adjusting the airflow accordingly.

[0004] In recent years, some existing technologies have emerged that control airflow based on a variety of detection data.

[0005] Patent document 1 discloses a control system and method for an air purification device, which determines different operating modes by comparing the pollutant concentration within a certain period of time with a preset range. The operating modes include: different speed switching modes, an on mode, and an off mode.

[0006] Patent document 2 discloses an energy-saving control method for an air purifier. It detects the concentration of air pollution and, when the air quality is determined to be at an excellent level, the air purifier can still display the current air quality status in real time. At the same time, the motor, buzzer, auxiliary function parts, and auxiliary function display parts in the air purifier display screen are all in a stopped working state. When the air quality deteriorates, the working parts in the air purifier resume working, overcoming the current air purifier's simple working and stopping states.

[0007] Patent Document 1: CN104913454A;

[0008] Patent document 2: CN103604192A.

[0009] It should be noted that the above description of the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of the present invention and facilitating understanding by those skilled in the art. It should not be assumed that the above technical solutions are known to those skilled in the art simply because they have been described in the background section of this invention. Summary of the Invention

[0010] However, the inventors discovered that in the aforementioned common prior art, even if the total amount of particulate matter remains unchanged, the concentration distribution of particulate matter of different sizes has a significant impact on indoor air quality. Controlling air purifiers solely based on the total number and concentration of indoor particulate matter cannot effectively purify particulate matter of different sizes, meaning that targeted purification is not possible, resulting in low purification efficiency and poor energy saving.

[0011] In addition, in Patent Document 1, the air purification device is controlled to be in different modes using the current pollutant concentration data. It is controlled only based on the current pollutant concentration data, which requires continuous monitoring, resulting in a slow processing speed and poor energy-saving performance of the device.

[0012] In Patent Document 2, the air quality level is determined based on the real-time detected air pollution concentration to control the air purifier. This also requires continuous monitoring, resulting in a slow processing speed and poor energy efficiency.

[0013] To address at least one of the aforementioned problems, embodiments of the present invention provide a control method and apparatus for a purification device, and a purification device in general. This method predicts the pollutant concentration distribution at multiple future times based on collected current environmental parameters, and controls the purification device according to the predicted pollutant concentration distribution. Therefore, it can obtain the future pollutant concentration distribution without continuous monitoring, resulting in faster processing speed and improved energy efficiency. Furthermore, controlling the purification device based on the future concentration distribution leads to higher purification efficiency and better results. Thus, it enables efficient, rapid, and energy-saving air purification.

[0014] According to a first aspect of the present invention, a control method for a purification device is provided, the control method comprising: acquiring environmental parameters of an indoor space; predicting pollutant concentration distributions at multiple times after the current time based on the environmental parameters; and controlling at least one device parameter of the purification device based on the pollutant concentration distributions at multiple times after the current time.

[0015] According to a second aspect of the present invention, a control device for a purification device is provided, the control device comprising: an acquisition unit for acquiring environmental parameters of an indoor space; a prediction unit for predicting pollutant concentration distributions at multiple times after the current time based on the environmental parameters; and a control unit for controlling at least one device parameter of the purification device based on the pollutant concentration distributions at multiple times after the current time.

[0016] According to a third aspect of the present invention, a purification device is provided, the purification device including a control device for the purification device described in the second aspect of the present invention.

[0017] One of the beneficial effects of this invention is that, since the pollutant concentration distribution at multiple future times is predicted based on the collected current environmental parameters, and the purification equipment is controlled based on the predicted pollutant concentration distribution, the future pollutant concentration distribution can be obtained without continuous detection. This results in faster processing speed and improved energy efficiency. Furthermore, controlling the purification equipment based on the future concentration distribution leads to higher purification efficiency and better results. Therefore, air purification can be performed efficiently, quickly, and energy-savingly.

[0036] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0037] Example 1

[0038] Embodiment 1 of the present invention provides a control method for a purification device. Figure 1 This is a flowchart of the control method for the purification equipment according to Embodiment 1 of the present invention. Figure 1 As shown, the method includes:

[0039] Step 101: Obtain the environmental parameters of the indoor space;

[0040] Step 102: Predict the pollutant concentration distribution at multiple time points after the current time based on this environmental parameter; and

[0041] Step 103: Based on the pollutant concentration distribution at multiple times after the current time, control at least one device parameter of the purification equipment.

[0042] In this way, since the pollutant concentration distribution at multiple future moments is predicted based on the collected current environmental parameters, and the purification equipment is controlled according to the predicted pollutant concentration distribution, the future pollutant concentration distribution can be obtained without continuous monitoring. The processing speed is faster and the energy-saving performance of the equipment is improved. Furthermore, controlling the purification equipment based on the future concentration distribution makes the purification efficiency higher and the effect better. Therefore, air purification can be carried out efficiently, quickly and energy-savingly.

[0043] In this embodiment of the invention, the purification device can be of various types, such as an air purifier, a fresh air system, or an air conditioning device with air purification function.

[0044] In this embodiment of the invention, the purification device can be used in a home, or in a commercial or public setting.

[0045] For example, this purification equipment can be used in home environments, as well as in commercial environments such as offices, office buildings, shopping malls, or public environments such as schools.

[0046] In this embodiment of the invention, the control method of the purification equipment can be executed by the purification equipment itself, for example, by the controller of the purification equipment.

[0047] In this embodiment of the invention, an indoor home layout diagram can also be obtained. In this way, the pollutant concentration distribution at multiple times after the current time can be predicted based on the environmental parameters and the home layout diagram.

[0048] By combining indoor furniture layout diagrams to predict pollutant concentration distribution, purification efficiency and effectiveness can be further improved.

[0049] For example, the home layout plan includes at least one of the following elements: floor plan, furniture placement, orientation, and geographical location;

[0050] For example, the home layout plan is obtained based on building information models and / or interior images taken by cameras.

[0051] In step 101, the environmental parameters of the indoor space are obtained.

[0052] In embodiments of the present invention, for example, the environmental parameter may include at least one of temperature, humidity, particulate matter concentration of different particle sizes, VOC concentration, formaldehyde concentration, odor gas concentration, and carbon dioxide concentration.

[0053] In embodiments of the present invention, for example, the pollutant concentration distribution includes at least one of the following: the concentration distribution of particulate matter of different sizes in an indoor space; the concentration distribution of VOCs in an indoor space; the concentration distribution of formaldehyde in an indoor space; the concentration distribution of odorous gases in an indoor space; and the concentration distribution of carbon dioxide in an indoor space.

[0054] In this embodiment of the invention, the environmental parameter can be obtained by multiple sensors arranged in different locations indoors or by at least one sensor that can move indoors.

[0055] For example, the environmental parameter includes at least one environmental parameter sequence of environmental parameters at at least one location point indoors at consecutive times.

[0056] Accordingly, in step 102, the at least one environmental parameter sequence can be input into the prediction model to output the pollutant concentration distribution at multiple times after the current time.

[0057] In this embodiment of the invention, the environmental parameter may include multiple environmental parameters at different indoor heights. This further improves the accuracy of prediction, thereby further enhancing the efficiency and effectiveness of purification.

[0058] In this embodiment of the invention, the higher the accuracy of the prediction of pollutant concentration distribution, the more environmental parameters at more locations are used to predict the concentration distribution.

[0059] For example, the environmental parameters include four environmental parameter sequences for eight consecutive time points at four indoor locations. In step 102, these four environmental parameter sequences are input into the prediction model as four channels, and the pollutant concentration distribution for multiple time points after the current time is output.

[0060] In this way, the four location points almost completely cover the detection of environmental parameters throughout the entire indoor area. The four location points can evenly divide the indoor space into four parts, each with a data reference, which can reduce costs while ensuring accuracy.

[0061] In this embodiment of the invention, the prediction model can be a deep neural network model or a simulation model.

[0062] For example, the prediction model is a deep neural network that includes a long short-term memory (LSTM) structure or a gated recurrent unit (GRU) structure.

[0063] For example, the prediction model is a computational fluid dynamics (CFD) simulation model.

[0064] The following is an exemplary description of the training process of a deep neural network as a prediction model.

[0065] Figure 2 This is a flowchart of the method for training a prediction model according to Embodiment 1 of the present invention. Figure 2 As shown, the method includes:

[0066] Step 201: Obtain the input of the four CHANNELs corresponding to the four location points. The input of each CHANNEL is the environmental parameter data of 8 consecutive time points.

[0067] Step 202: Each CHANNEL is processed by a Long Short-Term Memory (LSTM) neural network or a Gate Recurrent Unit (GRU) neural network to calculate the value of an extracted feature;

[0068] Step 203: Stack the units of each CHANNEL obtained in step 202. The result is an output of 4 units with future information, which is the time feature layer.

[0069] In this embodiment of the invention, the output of the time feature layer can be used to determine the control commands for future purification equipment.

[0070] Figure 3 This is a schematic diagram of the input data of the four CHANNELs obtained in step 201 of embodiment 1 of the present invention; Figure 4 This is a schematic diagram of each CHANNEL in step 202 of embodiment 1 of the present invention passing through a Long Short-Term Memory (LSTM) neural network.

[0071] like Figure 3 As shown, the input to a CHANNEL is particulate matter data of different sizes at eight consecutive time points. In this example, the eight consecutive time points are spaced one hour apart, but other time intervals can also be used, and this embodiment of the invention does not limit this.

[0072] like Figure 4 As shown, each time point of each channel is sequentially fed into an LSTM or GRU neural network layer. For example, data at 8:00 is input into the network layer at T=0, and data at 9:00 is input into the network layer at T=1. T=0 and T=1 are the same network layer, just representing different times. In this way, the neural network can learn the relationships between different sequences, thus gaining the ability to predict future data.

[0073] In this embodiment of the invention, the prediction model is continuously optimized through iteration, resulting in increasingly accurate predictions of pollutant concentration distributions and more precise corresponding control commands. The trained prediction model is saved for direct use later, allowing for the accurate acquisition of pollution source concentration distributions at multiple future points in time. For example, based on these future pollutant concentration distributions, the size of air inlets and outlets can be predicted in advance, thereby improving purification efficiency. Instead of repeatedly monitoring pollutant concentration distributions, adjustments and controls are made based on actual conditions until complete purification, thus enhancing energy-saving performance.

[0074] In this embodiment of the invention, prediction can also be made by combining indoor environmental equipment and user behavior.

[0075] For example, in step 102, the at least one environmental parameter sequence, the status of indoor environmental equipment, and / or user behavior are input into the prediction model to output the pollutant concentration distribution at multiple times after the current time.

[0076] This allows for further improvement in the precision of adjustments to the purification equipment, thereby enhancing purification efficiency and effectiveness.

[0077] In this embodiment of the invention, indoor environmental devices include, for example, air conditioners, humidifiers, robot vacuum cleaners, and fresh air systems, and user behaviors include, for example, smoking, opening windows, and cooking.

[0078] Figure 5 This is a schematic diagram of the predicted concentration distribution in Embodiment 1 of the present invention. Figure 5 As shown, at least one environmental parameter sequence, the status of indoor environmental equipment, and user behavior are input into the prediction model to obtain the pollutant concentration distribution at multiple time points after the current time.

[0079] In this embodiment of the invention, the device parameter can be various parameters involved in air purification treatment. For example, the device parameter is at least one of the number of air inlets that are open or closed, the opening and closing range, and the opening and closing angle; or, at least one of the number of air outlets that are open or closed, the opening and closing range, and the opening and closing angle; or, the wind force; or, the operating mode.

[0080] For example, in step 102, the air inlet and outlet of the purification equipment are controlled according to the predicted pollutant concentration distribution.

[0081] In this way, by controlling the air inlet and outlet in both directions based on the predicted pollutant concentration distribution, the purification efficiency and effect can be further improved.

[0082] In this embodiment of the invention, the quantity of pollutants at multiple times after the current time can be determined based on the predicted pollutant concentration distribution, and the purification equipment can be controlled according to the quantity of pollutants.

[0083] Figure 6 This is another flowchart of the control method for the purification equipment in Embodiment 1 of the present invention. Figure 6 As shown, the control method includes:

[0084] Step 601: Obtain environmental parameters of the indoor space;

[0085] Step 602: Predict the pollutant concentration distribution at multiple time points after the current time based on the environmental parameter;

[0086] Step 603: Determine the quantity of pollutants based on the pollutant concentration distribution at multiple times after the current time.

[0087] Step 604: Control at least one device parameter of the purification equipment based on the amount of pollutants at multiple times after the current time.

[0088] In this way, the quantity of pollutants determined based on the concentration distribution is accurate and can reflect the distribution characteristics. Controlling the purification equipment based on this quantity of pollutants can further improve the purification effect and efficiency.

[0089] For example, based on obtaining the concentration distribution of particles of different sizes in the future, the number of particles of different sizes can also be calculated; the accuracy and number of air inlets can be further controlled according to the number; if large-diameter particles are at the bottom of the entire indoor space, the number and height of air inlets can be increased to quickly draw in particles and achieve rapid purification.

[0090] In an embodiment of the invention, for example, the pollutant concentration is multiplied by the volume to obtain the pollutant quantity.

[0091] Alternatively, a lookup table can be created by actually detecting the amount of pollutants, and the future amount of pollutants can be obtained by using the lookup table method based on the predicted pollutant concentration distribution.

[0092] In this embodiment of the invention, an environmental sensor may also be installed on the purification device to detect obstacles in the environment.

[0093] like Figure 1 As shown, the method may further include:

[0094] Step 104: Based on the detection results of obstacles around the purification equipment, control at least one of the following: the number of openings and closings of the air inlet and the air outlet, the opening and closing range, and the opening and closing angle.

[0095] In this way, when obstacles are detected around the purification equipment, the parameters of the air inlet and outlet can be controlled in a timely manner, thereby improving the energy-saving performance of the equipment while ensuring the purification effect.

[0096] Figure 7 These are some examples of controlling the air inlet and outlet based on obstacles in Embodiment 1 of the present invention. For example... Figure 7 As shown, for air purifiers with a three-sided cross-section, based on the detection results of the surrounding walls, one air inlet and outlet are closed, or two air inlets and outlets are closed; for air purifiers with a circular cross-section, the air inlet and outlet are closed within a 90-180 degree angle range based on the detection results of the surrounding walls; for air purifiers with a four-sided cross-section, based on the detection results of the surrounding walls, one air inlet and outlet are closed, or two air inlets and outlets are closed, or the air inlets and outlets are not closed, i.e., all air inlets and outlets are fully open.

[0097] In this embodiment of the invention, the device parameter can be various parameters involved in air purification treatment. For example, the device parameter is at least one of the number of air inlets that are open or closed, the opening and closing range, and the opening and closing angle; or, at least one of the number of air outlets that are open or closed, the opening and closing range, and the opening and closing angle; or, the wind force; or, the operating mode.

[0098] The following is a detailed explanation of how to control the air inlet and outlet of the purification equipment based on the predicted concentration distribution of pollutants.

[0099] For example, in step 103, when it is determined that the pollutants are increasing or decreasing based on the pollutant concentration distribution at multiple times after the current time, the number of air inlets and outlets that are opened, the opening range, or the opening angle are controlled to increase or decrease accordingly.

[0100] For example, in step 604, when it is determined that the pollutants are increasing or decreasing based on the amount of pollutants at multiple times after the current time, the number of air inlets and outlets that are opened, the opening range, or the opening angle are controlled to increase or decrease accordingly.

[0101] In this way, based on the expected pollutant concentration distribution or quantity at different future times, the control commands can predict in advance and accordingly generate the control range for the size, number, and airflow of the air inlet and outlet of the purification equipment, thus achieving optimal purification results. Furthermore, this avoids the need for re-testing and resetting, thereby further saving energy.

[0102] Furthermore, in this embodiment of the invention, the control is not limited to bidirectional control of the air inlet and outlet, but can also be multidirectional.

[0103] In this embodiment of the invention, in step 103, at least one control strategy and the time required for the purification device to execute the control strategy may also be determined.

[0104] When multiple control strategies are determined, the time required for each strategy can be different. For example, multiple control strategies may correspond to different inlet and outlet sizes and different air volumes.

[0105] For example, a control strategy can be selected, which can automatically choose the control strategy that requires the shortest time, or it can be selected by the user.

[0106] Figure 8 This is a flowchart of a method for implementing step 103 of Embodiment 1 of the present invention. For example... Figure 8 As shown, the method includes:

[0107] Step 801: Based on the pollutant concentration distribution at multiple times after the current time, determine at least one control strategy and the time required for the purification equipment to execute the control strategy;

[0108] Step 802: Determine at least one control policy and provide it to the user; and

[0109] Step 803: Control the purification device according to the control strategy selected by the user.

[0110] This will further enhance the user experience.

[0111] Figure 9 This is a flowchart of another method for implementing step 103 of Embodiment 1 of the present invention. For example... Figure 9 As shown, the method includes:

[0112] Step 901: Based on the pollutant concentration distribution at multiple times after the current time, determine at least one control strategy and the time required for the purification equipment to execute the control strategy;

[0113] Step 902: Automatically select the control strategy with the shortest required time from at least one control strategy; and

[0114] Step 903: Control the purification equipment according to the automatically selected control strategy.

[0115] In embodiments of the present invention, the method may further include:

[0116] When the noise level of the purification device exceeds the preset threshold, the noise reduction module is activated.

[0117] For example, after the noise cancellation module is activated, it plays music, or sounds that promote sleep or rest.

[0118] In this way, when the purification process of the air purifier causes a lot of noise, playing music can enhance the atmosphere and improve the user experience.

[0119] In addition, this invention also discloses a control method for a purification device. Figure 10 This is another flowchart of the control method for the purification equipment in Embodiment 1 of the present invention, as shown below. Figure 10 As shown, the control method includes:

[0120] Step 1001: Obtain historical pollutant concentration distribution data;

[0121] Step 1002: Input historical pollutant concentration distribution data into the prediction model based on LSTM units, and output the pollution source concentration distribution at different future times;

[0122] Step 1003: Calculate the amount of pollutants at different future times;

[0123] Step 1004: Output control commands to sequentially increase or decrease the area of ​​the air outlet;

[0124] Step 1005: Control the area of ​​the air outlet to increase or decrease sequentially according to the control command.

[0125] As can be seen from the above embodiments, since the pollutant concentration distribution at multiple times after the current moment is predicted based on the collected current environmental parameters, and the purification equipment is controlled according to the predicted pollutant concentration distribution, the future pollutant concentration distribution can be obtained without continuous detection. The processing speed is faster and the energy-saving performance of the equipment is improved. Furthermore, controlling the purification equipment based on the future concentration distribution makes the purification efficiency higher and the effect better. Therefore, air purification can be carried out efficiently, quickly and energy-savingly.

[0126] Example 2

Its specific implementation can refer to the implementation of the method described in Embodiment 1. The same or related contents will not be repeated.

[0128] Figure 11 This is a schematic diagram of the control device of the purification equipment in Embodiment 2 of the present invention, as shown below. Figure 11 As shown, the control device 1100 of the purification equipment includes:

[0129] Acquisition unit 1101 is used to acquire environmental parameters of the indoor space;

[0130] Prediction unit 1102 is used to predict the pollutant concentration distribution at multiple time points after the current time based on the environmental parameter; and

[0131] Control unit 1103 is used to control at least one device parameter of the purification equipment based on the pollutant concentration distribution at multiple times after the current time.

[0132] In this embodiment of the invention, the functions of the above-mentioned units can be implemented with reference to the relevant steps in Embodiment 1, and will not be repeated here.

[0133] In this embodiment of the invention, the control device 1100 of the purification equipment can be installed in the purification equipment or can be used as a separate device.

[0134] In addition to the control functions described in the embodiments of the present invention, the control device 1100 of the purification equipment may also include other control functions, such as power switch control, timer control, etc.

[0135] As can be seen from the above embodiments, since the pollutant concentration distribution at multiple times after the current moment is predicted based on the collected current environmental parameters, and the purification equipment is controlled according to the predicted pollutant concentration distribution, the future pollutant concentration distribution can be obtained without continuous detection. The processing speed is faster and the energy-saving performance of the equipment is improved. Furthermore, controlling the purification equipment based on the future concentration distribution makes the purification efficiency higher and the effect better. Therefore, air purification can be carried out efficiently, quickly and energy-savingly.

[0136] Example 3

[0137] Embodiment 3 of the present invention provides a purification device, which includes the control device of the purification device described in Embodiment 2. The specific implementation can refer to the implementation of the device described in Embodiment 2 and the method described in Embodiment 1. The same or related contents will not be repeated.

[0138] In embodiments of the present invention, for example, the control device of the purification equipment described in Embodiment 2 is a controller in the purification equipment, or the control device is integrated into the controller of the purification equipment.

[0139] Figure 12 This is a structural diagram of the purification device according to Embodiment 3 of the present invention, as shown below. Figure 12 As shown, the purification device 1200 includes:

[0140] Control device (not in) Figure 12 (as shown in the image);

[0141] The outer casing 1210 has air inlets 1211 and 1212 at the lower end of its peripheral side and at the bottom.

[0142] The inner shell 1220 has air outlets 1221 and 1222 on its peripheral side and upper side;

[0143] The inner housing 1210 is embedded within the outer housing 1220 and is adjusted vertically via a mechanism (not in the outer housing). Figure 12 (As shown in the image) Adjust the height;

[0144] The filter body mechanism 1230 is disposed within the inner housing 1420;

[0145] Fan (not in) Figure 12 (as shown in the figure), it is disposed within the inner housing or outer housing;

[0146] The system includes a first air guide plate at the air inlet and a second air guide plate at the air outlet.

[0147] The control device controls at least one of the air inlet, air outlet, vertical adjustment mechanism, first air guide plate and second air guide plate according to the control command.

[0148] In addition, such as Figure 12 As shown, an air inlet 1223 is also provided at the bottom of the inner casing 1220.

[0149] In this embodiment of the invention, the first air guide plate can be disposed inside the inner shell 1220. The first air guide plate is disposed on the peripheral side of the inner shell and is perpendicular to the upper side of the inner shell. Furthermore, the first air guide plate is distributed in a rotating manner.

[0150] Figure 13 This is a schematic diagram showing various states of the first air guide plate in Embodiment 3 of the present invention. For example... Figure 13 As shown in (A), when the air inlet 1211 is closed, the first air guide plate 1213 is closed; as Figure 13 As shown in (B), when an obstacle is detected around the purification device, the first air guide plates 1213 on all four sides open in the same direction and rotate; Figure 13 As shown in (C), when there are obstacles around a part of the air inlet 1211, the first air guide plate 1213 corresponding to the location of the obstacle can be closed, and the other first air guide plates 1213 open in the same direction and rotate.

[0151] In this way, the first air guide plate is set in a rotating shape, which improves the air intake effect and provides a rotating air intake; it can intake air according to the rotation direction of the fan, thus improving the efficiency of the fan; in addition, the air in the indoor space can be in a dynamic rotating state.

[0152] In addition, the first air guide plate on each side can be controlled independently.

[0153] In this embodiment of the invention, the second air guide plate may include an air guide door, the size of which is the same as that of the air outlet, and the air guide door controls the opening area of ​​the air outlet according to the control command of the control device.

[0154] In this embodiment of the invention, a liftable third air guide plate may be provided on the air outlet 1222 on the upper side of the inner housing 1220. Figure 14 This is a schematic diagram showing two states of the third air guide plate in Embodiment 3 of the present invention. Figure 14 As shown in (A) and (B), the angle and opening area of ​​the third air guide plate 1224 can be changed by adjusting the height of the third air guide plate, thereby improving the air outlet efficiency and purification efficiency.

[0155] like Figure 12 As shown, the filter body 1230 includes a first filter screen, a second filter screen, and a third filter screen.

[0156] The first filter, the second filter, and the third filter are arranged in parallel; the second filter is located between the air inlet and the air outlet of the inner housing 1220, and the first filter is located inside the inner housing 1220.

[0157] Alternatively, the first filter 1231 can also be disposed inside the outer casing 1210.

[0158] in addition, Figure 12 The individual filters are shown only schematically, without indicating their location within the purification unit 1200.

[0159] In this way, the filter stacking arrangement results in a longer filtration path and a better purification effect. When the inner shell is raised by controlling the up-and-down adjustment mechanism, the air inlet at the bottom of the inner shell's perimeter first draws in a large amount of small-diameter particles from the upper air intake, and after a period of time, it moves to the lower air intake to draw in large-diameter particles. This works in conjunction with the bottom air inlet to achieve a better purification effect.

[0160] In this embodiment of the invention, a predetermined space may exist between the second filter and the third filter. This allows the second and third filters to be loosely connected, creating a movable space and gaps between them, resulting in a better purification environment.

[0161] In this embodiment of the invention, lighting lamps can be provided at the air outlet and air inlet, and the length of the lighting lamps is consistent with the length of the corresponding air inlet and air outlet.

[0162] In this way, the movement of particulate matter can be clearly seen under the light, and the difference between the particulate matter at the air inlet and the air outlet is visualized, resulting in better purification. At the same time, it can also be used as a light at night. Of course, the color and length of the light can be changed, and with the addition of music in the entertainment mode, the user experience will be even better.

[0163] In this embodiment of the invention, the purification device 1200 can be used in a home, or in a commercial or public setting.

[0164] For example, the 1200 purification equipment can be used in home environments, as well as in commercial environments such as offices, office buildings, shopping malls, or public environments such as schools.

[0165] As can be seen from the above embodiments, since the pollutant concentration distribution at multiple times after the current moment is predicted based on the collected current environmental parameters, and the purification equipment is controlled according to the predicted pollutant concentration distribution, the future pollutant concentration distribution can be obtained without continuous detection. The processing speed is faster and the energy-saving performance of the equipment is improved. Furthermore, controlling the purification equipment based on the future concentration distribution makes the purification efficiency higher and the effect better. Therefore, air purification can be carried out efficiently, quickly and energy-savingly.

The present invention relates to a computer-readable program that, when executed by a logic component, enables the logic component to implement the aforementioned apparatus or constituent parts, or to implement the various methods or steps described above.

[0168] It should be noted that the limitations on each step involved in this solution are not considered as limiting the order of steps, provided that they do not affect the implementation of the specific solution. The steps listed first can be executed first, later, or even simultaneously. As long as this solution can be implemented, it should be considered to fall within the scope of protection of this application.
