Description

Technical Field

[0001] The present invention relates to the field of air purification, and in particular to a control method and device for purification equipment, and purification equipment. Background Art

[0002] As people's requirements for quality of life continue to increase and air pollution becomes increasingly serious, air purification technology has gradually attracted people's attention.

[0003] As one of the main pollutants in indoor air, particulate matter in the air affects the health of people indoors. Most existing air purification technologies and air purifier products only focus on the total amount of indoor particulate matter. Common existing technologies can detect the total number concentration of indoor particulate matter and then adjust the air volume to achieve the purpose of quickly purifying indoor air.

[0004] In recent years, some existing technologies for controlling air output according to various detection data have emerged.

[0005] Patent document 1 discloses an air purifier that changes the air volume of an air supply unit, the position of a panel, and the area of ​​a louver by detecting the particle diameter of an object in a detection area.

[0006] Patent document 2 discloses an air purifier that adjusts the angle and volume of wind blowing to achieve the optimal state by detecting indoor information such as indoor area, obstacles, and wall distance.

[0007] Patent document 1: CN106907791A;

[0008] Patent document 2: CN105659033B.

[0009] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present invention and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are described in the background technology section of the present invention. Summary of the invention

[0010] However, the inventors have found that in the above-mentioned common prior art, even if the total amount of particulate matter remains unchanged, the concentration distribution of particles of different particle sizes is also crucial to the indoor air quality. Controlling the air purifier based only on the total number concentration of indoor particles cannot purify particles of different particle sizes well, that is, it cannot purify in a targeted manner, resulting in low purification efficiency and inability to save energy well.

[0011] In addition, in Patent Document 1, the air purifier changes the output of the air supply unit only according to the output of the pollution detection unit and the diameter of the particles of the detection object passing through the detection area. It does not take into account the differences in the distribution of particles of different particle sizes in the room. For example, the particles in the detection area are purified, and only small-diameter particles exist in the detection area around the purifier, but there are a large number of large-diameter particles in other areas. Therefore, the air volume, panel position and air window area controlled by the control unit do not conform to the actual distribution of indoor particles, resulting in incomplete purification effect.

[0012] In Patent Document 2, the air purifier uses the change of the air guide device to adjust the outlet angle of the air outlet and the air volume based on the detection information of the indoor environment by the external detection device. It does not take into account the distribution of indoor particulate matter. In addition, the control of the avoidance mode, that is, the air volume remains unchanged, the air outlet becomes smaller, and the wind speed becomes faster, will bring discomfort to people, and the purification area is small.

[0013] In order to solve at least one of the above problems, the embodiments of the present invention provide a control method and device for purification equipment, and purification equipment, which control the purification equipment according to the concentration distribution of particles of different particle sizes in the indoor space. Therefore, targeted control can be performed on particles of different particle sizes, thereby improving the purification efficiency and speed, and achieving good purification effects efficiently and quickly.

[0014] According to a first aspect of an embodiment of the present invention, a control method for a purification device is provided, the control method comprising: determining a concentration distribution of particles of different particle sizes in an indoor space; and controlling at least one device parameter of the purification device according to the concentration distribution of particles of different particle sizes in the indoor space.

[0015] According to a second aspect of an embodiment of the present invention, a control device for a purification device is provided, the control device comprising: a determination unit for determining the concentration distribution of particles of different particle sizes in an indoor space; and a control unit for controlling at least one device parameter of the purification device according to the concentration distribution of particles of different particle sizes in the indoor space.

[0016] According to a third aspect of the embodiments of the present invention, a purification device is provided, the purification device comprising the control device of the purification device according to the second aspect of the embodiments of the present invention, which controls at least one device parameter of the purification device.

[0017] One of the beneficial effects of the embodiments of the present invention is that since the purification equipment is controlled according to the concentration distribution of particles of different particle sizes in the indoor space, targeted control can be performed on particles of different particle sizes, thereby improving the purification efficiency and speed, and achieving a good purification effect efficiently and quickly.

[0040] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0041] Example 1

[0042] Embodiment 1 of the present invention provides a control method for purification equipment. Figure 1 : is a flow chart of a control method of a purification device according to Embodiment 1 of the present invention. Figure 1 As shown, the method includes:

[0043] Step 101: Determine the concentration distribution of particles of different particle sizes in the indoor space; and

[0044] Step 102: Control at least one device parameter of the purification device according to the concentration distribution of the particles of different particle sizes in the indoor space.

[0045] In this way, since the purification equipment is controlled according to the concentration distribution of particles of different particle sizes in the indoor space, targeted control can be performed on particles of different particle sizes, thereby improving the purification efficiency and speed, and achieving a good purification effect efficiently and quickly.

[0046] In the embodiment of the present invention, for example, the concentration distribution may refer to distribution in two dimensions: distribution of different particle sizes and distribution of the number of each particle size.

[0047] In the embodiment of the present invention, the purification device may be various types of purification devices, such as an air purifier, a fresh air device, or an air conditioning device with an air purification function.

[0048] In the embodiment of the present invention, the purification device can be used for household, commercial or public use.

[0049] For example, the purification device 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.

[0050] In the embodiment of the present invention, the control method of the purification device may be executed by the purification device, for example, by a controller of the purification device.

[0051] In step 101, the concentration distribution of particles of different particle sizes in an indoor space is determined.

[0052] In the embodiment of the present invention, particles of different particle sizes can be roughly divided into, for example, large particle size particles and small particle size particles;

[0053] Alternatively, particles of different sizes may also be classified according to a unified standard, for example, PM10 particles and PM2.5 particles.

[0054] In the embodiment of the present invention, the concentration distribution of particulate matter in the indoor space refers to the distribution of the concentration of particulate matter at different spatial positions in the room, for example, the distribution of the concentration at different heights in the room.

[0055] The following is a detailed description of the implementation method of step 101.

[0056] Figure 2 is a flow chart of a method for implementing step 101 of embodiment 1 of the present invention, such as Figure 2 As shown, the method includes:

[0057] Step 201: Acquire temperature and / or humidity data of an indoor space; and

[0058] Step 202: Determine the concentration of particles of different sizes corresponding to the temperature and / or humidity at different heights by looking up a table, and obtain the concentration distribution of particles of different sizes in the indoor space.

[0059] In this way, the concentration distribution of particles of different particle sizes in the indoor space can be obtained conveniently and quickly through the table lookup method.

[0060] In the embodiment of the present invention, the temperature and / or humidity data of the indoor space is obtained, for example, by an indoor temperature sensor and / or humidity sensor, which may be multiple sensors at different positions indoors or a sensor that can move indoors.

[0061] In an embodiment of the present invention, for example, the lookup table is a pre-established table and stored in a database.

[0062] For example, tests are conducted in advance under different temperature and / or humidity conditions to obtain the concentrations of particles of different sizes at different heights, and these data are recorded and a lookup table is established.

[0063] Figure 3 FIG. 1 is an example diagram of a lookup table according to Embodiment 1 of the present invention. Figure 3 As shown in the figure, with the increase of temperature and humidity, the distribution position of the particles gradually decreases.

[0064] In step 202, the database is accessed and the lookup table is obtained in the database for comparison to determine the concentration of particles of various particle sizes corresponding to the temperature and / or humidity at different altitudes.

[0065] For example, in the lookup table, for lower altitudes, the greater the humidity, the greater the corresponding concentration of large-size particles, and the lower the humidity, the greater the corresponding concentration of small-size particles.

[0066] In this way, for example, the greater the humidity, the larger the particles will sink. The distribution determined by the table lookup method can make the purification more targeted and the purification effect better.

[0067] Figure 4 : is a graph showing the relationship between the number concentration distribution of indoor particulate matter and ventilation and natural wind in Example 1 of the present invention; Figure 4 As shown, under the condition of constant temperature and humidity, the particle distributions of natural ventilation and no ventilation are also different. The embodiment of the present invention can control the purification equipment based on this point.

[0068] Figure 5 is a flowchart of another method for implementing step 101 of embodiment 1 of the present invention, such as Figure 5 As shown, the method includes:

[0069] Step 501: Acquire temperature and / or humidity data of an indoor space; and

[0070] Step 502: Input the temperature and / or humidity data and the height information into the first neural network model to obtain the concentration distribution of particles of different particle sizes in the indoor space.

[0071] In this way, the concentration distribution of particles of different sizes in the indoor space is determined by the first neural network model with high efficiency and accuracy.

[0072] Step 501 is similar to step 201 and will not be described in detail here.

[0073] In step 502, the temperature and / or humidity data and height information are input into the first neural network model to obtain the concentration distribution of particles of different particle sizes in the indoor space. The height information is, for example, the indoor height and / or the height of the floor where the purification equipment is located.

[0074] In this way, when determining the concentration distribution of particles of different particle sizes in the indoor space, height factors such as different indoor heights and floor heights are taken into consideration. Accordingly, different control strategies will be generated to make the purification effect stronger.

[0075] In an embodiment of the present invention, the first neural network model is a pre-trained model.

[0076] The following is an exemplary description of the training method of the first neural network model.

[0077] Figure 6 : is a flow chart of the method for training the first neural network model according to Embodiment 1 of the present invention. Figure 6 As shown, the method includes:

[0078] Step 601: Input current temperature, humidity and altitude parameters;

[0079] Step 602: Use the configured fully connected neural network for training;

[0080] Step 603: After the model training is completed, the model is saved.

[0081] Figure 7 1 is a schematic diagram of the first neural network training of the embodiment 1 of the present invention. Figure 7 As shown, the first neural network is a fully connected neural network, wherein the input T represents temperature, RH represents relative humidity, H represents height, and P represents particle concentration, that is, the parameters of temperature, humidity and at least one height are input, and the predicted particle concentration values ​​of different particle sizes are output through the fully connected network.

[0082] After the first neural network model is designed, it is necessary to find the optimal value of the model through training configuration, that is, to measure the quality of the model through the loss function, and use the mean square error as the standard for evaluating the quality of the model. For example, the loss function is expressed by the following formula (1):

[0083] Loss=(p 预测 —p 真实 ) 2 (1)

[0084] Among them, Loss represents the loss value, p 预测 represents the particle concentration value output by the first neural network, p 真实 Indicates the true value of the particle concentration.

[0085] The corresponding gradient value can be obtained by reverse derivation, that is, the corrected gradient value. After minimizing LOSS, the corresponding gradient value is more accurate; it will be more accurate when the model is used forward. After the training is completed, the model can be saved.

[0086] Figure 8 is a flowchart of another method for implementing step 101 of embodiment 1 of the present invention, such as Figure 8 As shown, the method includes:

[0087] Step 801: Obtain sensor values ​​of indoor particles of different particle sizes; and

[0088] Step 802: fitting the concentration distribution of particles with different particle sizes in the indoor space according to the numerical values ​​of the sensors of particles with different particle sizes in the room.

[0089] In this way, the concentration distribution of particles of different sizes in the indoor space is fitted by the actual detection values ​​of the particle sensor, and the result is more accurate.

[0090] In the embodiment of the present invention, for example, multiple sensors are used in the room to detect particles with different particle sizes. For another example, the multiple sensors are arranged at different heights in the room.

[0091] For example, a plurality of PM2.5 sensors and / or a plurality of PM10 sensors are arranged at different heights indoors.

[0092] In addition, multiple sensors of other different particle sizes may also be included, for example, PM0.5, PM1, PM2, PM3, PM4 and PM5.

[0093] Fig. 9 FIG. 1 is a schematic diagram of the concentration distribution of the fitted particulate matter in the room according to Example 1 of the present invention. Fig. 9As shown in FIG. 1 , for particles of a certain size, the 3D distribution of the particle concentration in the room is fitted based on the particle concentration values ​​at multiple locations measured by the sensor. In addition, similar fitting can be performed for particles of other sizes.

[0094] In the above, the determination of the current concentration distribution of particles of different particle sizes in the indoor space in step 101 is described. In addition, in the embodiment of the present invention, the concentration distribution of particles of different particle sizes in the indoor space in the future can also be predicted.

[0095] Fig.10 is a flowchart of another method for implementing step 101 of embodiment 1 of the present invention, such as Fig.10 As shown, the method includes:

[0096] Step 1001: Acquire temperature and / or humidity data of an indoor space; and

[0097] Step 1002: Based on the temperature and / or humidity data of the indoor space, predict the concentration distribution of particles of different particle sizes in the indoor space at multiple moments after the current moment.

[0098] Accordingly, in step 102, the control instruction for at least one device parameter is adjusted in real time according to the concentration distribution of particles of different particle sizes in the indoor space at the multiple moments.

[0099] In this way, the control of the air purifier can be adjusted in real time according to the predicted future concentration distribution of particles of different particle sizes in the indoor space, which can further improve the purification efficiency and purification effect.

[0100] In the embodiment of the present invention, the prediction can be performed through a neural network or a simulation model.

[0101] For example, the temperature and / or humidity data and the height information are input into the second neural network model to obtain the concentration distribution of particles of different particle sizes in the indoor space at multiple moments after the current moment.

[0102] For another example, the temperature and / or humidity data and the height information are input into a simulation model to obtain the concentration distribution of particles of different sizes in the indoor space at multiple moments after the current moment.

[0103] When using neural networks to predict the future concentration distribution of particles of different sizes in indoor spaces, predictions can also be made based on data from particle sensors and in combination with indoor environmental equipment and user behavior.

[0104] For example, multiple particle data sequences at different indoor locations and the status of indoor environmental equipment and / or user behavior are input into the third neural network model to obtain the concentration distribution of particles of different sizes in the indoor space at multiple moments after the current moment.

[0105] In an embodiment of the present invention, the third neural network model may be a trained deep neural network including a long short-term memory (LSTM) structure or a gated recurrent unit (GRU) structure.

[0106] In the embodiment of the present invention, indoor environment equipment includes, for example, air conditioners, humidifiers, sweeping robots, and fresh air equipment, and user behaviors include, for example, smoking, opening windows, and cooking.

[0107] Fig.11 Schematic diagram of the predicted concentration distribution of Example 1 of the present invention. Fig.11 As shown, multiple particle data sequences at different indoor locations, the status of indoor environmental equipment, and user behavior are input into the third neural network model to obtain the concentration distribution of particles of different sizes in the indoor space at multiple moments after the current moment.

[0108] In this way, the adjustment accuracy of the equipment parameters of the purifier can be further improved, thereby further improving the purification efficiency and purification effect.

[0109] In the embodiment of the present invention, the simulation model is, for example, a computational fluid dynamics (CFD) simulation model.

[0110] In the embodiment of the present invention, the concentration distribution of the particulate matter may also be determined in combination with the indoor home layout diagram.

[0111] Fig.12 FIG. 1 is a flowchart of another method for implementing step 101 of embodiment 1 of the present invention. Fig.12 As shown, the method includes:

[0112] Step 1201: Obtaining an indoor home layout diagram; and

[0113] Step 1202: Determine the concentration distribution of particles of different particle sizes in the indoor space in combination with the home layout diagram.

[0114] In this way, by determining the concentration distribution of particulate matter in combination with the indoor home layout, the purification efficiency and purification effect can be further improved.

[0115] For example, there are many floating particles behind the sofa or TV. Through targeted control and purification, the purification effect can reach the best state indoors.

[0116] In an embodiment of the present invention, a home layout diagram may be obtained through a BIM model and / or an indoor image captured by a camera. For example, the home layout diagram may include factors such as apartment type, home placement, orientation, and geographical location.

[0117] In the embodiment of the present invention, in addition to controlling the purification device according to the concentration distribution of particulate matter in the pollutants, the purification device may also be controlled according to the concentration distribution of other pollutants in the indoor space.

[0118] like Figure 1 As shown, the method may also include:

[0119] Step 103: Determine the concentration distribution of pollutants other than particulate matter in the indoor space; and

[0120] Step 104: Control at least one device parameter of the purification device according to the concentration distribution of the other pollutants in the indoor space.

[0121] In Example 1 of the present invention, steps 103-104 and steps 101-102 can be executed successively or in parallel. In addition, steps 102 and 104 can also be executed in combination, that is, at least one device parameter of the purification device is controlled according to the concentration distribution of particles of different particle sizes in the indoor space and the concentration distribution of other pollutants in the indoor space.

[0122] For example, other pollutants may include odors, formaldehyde, VOCs, and dust, among other pollutants.

[0123] In this way, the purification equipment can be controlled not only according to the concentration distribution of particulate matter, but also according to the concentration distribution of other pollutants in the indoor space, so that the purification equipment can purify the air comprehensively and efficiently, further improving the equipment performance and user experience.

[0124] In step 102 or step 104 , at least one device parameter of the purification device is controlled.

[0125] The device parameter may be various parameters involved in the air purification process, for example, the device parameter is at least one of the opening and closing number, opening and closing range, and opening and closing angle of the air inlet; or, at least one of the opening and closing number, opening and closing range, and opening and closing angle of the air outlet; or, the wind force; or, the operation mode.

[0126] For example, in step 102, the air inlet and the air outlet of the purification device are controlled according to the concentration distribution of particles of different particle sizes in the indoor space.

[0127] In this way, the purification efficiency and effect can be further improved by bidirectionally controlling the air inlet and outlet according to the concentration distribution of particles of different particle sizes in the indoor space.

[0128] In the embodiment of the present invention, an environmental sensor may also be provided on the purification device to sense obstacles in the environment.

[0129] like Figure 1 As shown, the method may also include:

[0130] Step 105: According to the detection result of the obstacles around the purification device, at least one of the opening and closing quantity, opening and closing range, and opening and closing angle of the air inlet and the air outlet is controlled.

[0131] In this way, when obstacles are detected around the purification equipment, the parameters of the air inlet and outlet can be controlled in time, thereby improving the energy-saving performance of the equipment while ensuring the purification effect.

[0132] Fig.13 These are some examples of controlling the air inlet and outlet according to obstacles in Embodiment 1 of the present invention. Fig.11 As shown, for the case where the cross-section of the air purifier is a three-sided structure, the air inlet and outlet on one side are closed according to the detection results of the surrounding walls, or the air inlet and outlet on two sides are closed; for the case where the cross-section of the air purifier is a circular structure, the air inlet and outlet are closed within an angle range of 90-180 degrees according to the detection results of the surrounding walls; for the case where the cross-section of the air purifier is a four-sided structure, the air inlet and outlet on one side are closed according to the detection results of the surrounding walls, or the air inlet and outlet on two sides are closed, or the air inlet and outlet are not closed, that is, the air inlet and outlet are fully opened.

[0133] The following is a specific description of controlling the air inlet and outlet of the purification device according to the concentration distribution of particles of different particle sizes in the indoor space.

[0134] Fig.14 FIG. 1 is a flow chart of a method for implementing step 102 of embodiment 1 of the present invention. Fig.14 As shown, the method includes:

[0135] Step 1401: controlling the opening range of the air inlet and the air outlet according to the concentration distribution of particles of different particle sizes in the indoor space; and

[0136] Step 1402: After the purification device has been running for a period of time, the opening range of the air inlet and the air outlet is changed according to the detection results or prediction results of particles of different particle sizes.

[0137] In this way, after a period of time according to the opening range of the particle concentration distribution, the opening range of the air inlet and the air outlet is changed according to the detection results or prediction results, so that the control of the air inlet and the air outlet can always ensure the optimization of purification efficiency and purification effect, thereby further improving equipment performance.

[0138] For example, when the concentration of large-size particles is high in a lower area indoors, the opening range of the air inlet and outlet is controlled in a lower area and the wind force is increased; and after the purification equipment has been running for a period of time, the opening range of the air inlet and outlet in height is gradually increased based on the detection results or prediction results of the particle matter.

[0139] For example, when the humidity is high, most of the large-size particles are deposited at the bottom. In this way, the opening range of the air inlet and outlet is controlled in a relatively low altitude area, and the wind force is increased. After the air circulates at the bottom for a period of time, the opening range of the air inlet and outlet is gradually increased from top to bottom according to the test results or prediction results. In this way, higher purification efficiency and better purification effect can be obtained.

[0140] For another example, when the concentration of large-size particulate matter in a lower area indoors is low, the air inlet and outlet are controlled to be open to the maximum range in height; and after the purification equipment has been running for a period of time, the opening range of the air inlet and outlet in height is gradually reduced based on the detection results or prediction results of the particulate matter.

[0141] For example, when the humidity is low, large-size particles will not sink indoors. The air inlet and outlet are controlled to open at the maximum range in height. After running the indoor large circulation for a period of time, the opening range of the air inlet and outlet in height is gradually reduced, and the particles are purified in an orderly manner, which can achieve higher purification efficiency and better purification effect.

[0142] In an embodiment of the present invention, the method may further include:

[0143] When the noise of the purification equipment is greater than a preset threshold, the noise reduction module is started.

[0144] For example, after the noise reduction module is started, it plays music, or plays sounds that promote sleep or rest, such as white noise.

[0145] In this way, when the noise is loud due to the purification process of the purification equipment, playing music or sound can create an atmosphere and enhance the user experience.

[0146] In addition, an embodiment of the present invention further discloses a control method for a purification device, the control method comprising:

[0147] Step S1: Obtain current temperature and humidity data;

[0148] Step S2: the memory module searches a lookup table containing particles of different particle sizes at corresponding temperatures and humidities at different altitudes;

[0149] Step S3: determining the current distribution state of the particles according to the search result of the lookup table;

[0150] Step S4: outputting the area size, quantity, and wind force control range of the corresponding air inlet and outlet according to the current distribution state of the particles;

[0151] Step S5: Control the operating state of the purification equipment according to the area size, number, and wind force control range of the air inlet and outlet;

[0152] Step S6: After the internal circulation is performed at the bottom of the indoor space for a period of time, a control instruction for controlling the area of ​​the air outlet to increase or decrease in sequence is output according to the distribution state of the particles at different times after the simulation;

[0153] Step S7: controlling the area of ​​the air outlet of the purification device to increase or decrease in sequence according to the area of ​​the air outlet increasing or decreasing in sequence.

[0154] It can be seen from the above embodiments that since the purification equipment is controlled according to the concentration distribution of particles of different particle sizes in the indoor space corresponding to different temperatures and humidity, targeted control can be performed on particles of different particle sizes, thereby improving the purification efficiency and speed, and achieving good purification effects efficiently and quickly.

[0162] In addition, the control device 1500 of the purification equipment may include other control functions, such as power switch control, timing control, etc., in addition to the control functions described in the embodiment of the present invention.

[0163] It can be seen from the above embodiments that since the purification equipment is controlled according to the concentration distribution of particles of different particle sizes in the indoor space, targeted control can be performed on particles of different particle sizes, thereby improving the purification efficiency and speed, and achieving a good purification effect efficiently and quickly.

Its specific implementation can refer to the implementation of the device described in Embodiment 2 and the method described in Embodiment 1, and the same or related contents will not be repeated.

[0166] In the embodiment of the present invention, for example, the control device of the purification device described in Embodiment 2 is a controller in the purification device, or the control device is integrated in the controller of the purification device.

[0167] Fig.16 is a structural diagram of a purification device according to Embodiment 3 of the present invention, Fig.16 As shown, the purification device 1600 includes:

[0168] Control device (not in Fig.16 )

[0169] The outer shell 1610 has air inlets 1611 and 1612 disposed at the lower end and bottom of the peripheral side thereof;

[0170] The inner shell 1620 has air outlets 1621 and 1622 arranged on its circumferential side and upper side;

[0171] The inner shell 1620 is embedded in the outer shell 1610 and is adjusted by an up and down adjustment mechanism (not shown). Fig.16 ) for lifting and lowering adjustment;

[0172] A filter body mechanism 1630 disposed within the inner housing 1620;

[0173] Fan (not in Fig.16), which is arranged in the inner shell or the outer shell;

[0174] Wherein, a first air guide plate is provided at the air inlet, and a second air guide plate is provided at the air outlet;

[0175] The control device controls at least one of the air inlet, the air outlet, the up and down adjustment mechanism, the first air guide plate and the second air guide plate according to the control instruction.

[0176] In addition, if Fig.16 As shown, an air inlet 1623 is also provided at the bottom of the inner shell 1620 .

[0177] In the embodiment of the present invention, the first air guide plate can be arranged in the inner shell 1620. The first air guide plate is arranged on the peripheral side of the inner shell and is perpendicular to the upper side of the inner shell. In addition, the first air guide plate is distributed in a rotating shape.

[0178] Fig.17 Schematic diagram of various states of the first air guide plate of Example 3 of the present invention. Fig.17 As shown in (A), when the air inlet 1611 is closed, the first air guide plate 1613 is closed; Fig.17 As shown in (B) in FIG. 1 , when obstacles are detected around the purification device, the first air guide plates 1613 on the four surfaces are opened in the same direction and rotated; Fig.17 As shown in (C), when there is an obstacle around a portion of the air inlet 1611, the first air guide plate 1613 corresponding to the position where the obstacle exists can be closed, and the other first air guide plates 1613 are opened in the same direction and rotated.

[0179] In this way, the first air guide plate is arranged in a rotating shape, and the air intake effect is better, and it is a rotating air intake; the air can be taken in according to the rotation direction of the fan, which improves the efficiency of the fan; in addition, the air in the indoor space can be in a dynamic rotating state.

[0180] In addition, the first air guide plates on each surface can be controlled individually.

[0181] In an embodiment of the present invention, the second air guide plate may include an air guide door, the size of the air guide door is consistent with the air outlet, and the air guide door controls the opening area of ​​the air outlet according to the control instruction of the control device.

[0182] In the embodiment of the present invention, a third air guide plate that can be raised and lowered may be provided on the air outlet 1622 on the upper side of the inner shell 1620 . Fig.18 Schematic diagram of two states of the third air guide plate of Example 3 of the present invention. Fig.18 As shown in (A) and (B), by raising and lowering the third air guide plate 1624, the angle and opening area of ​​the third air guide plate can be changed, thereby improving the air outlet efficiency and purification efficiency.

[0183] like Fig.16 As shown, the filter body mechanism 1630 includes a first filter screen, a second filter screen and a third filter screen.

[0184] The first filter, the second filter and the third filter are arranged in parallel; the second filter is arranged between the air inlet and the air outlet of the inner shell 1620, and the first filter is arranged inside the inner shell 1620.

[0185] In addition, the first filter may also be disposed in the outer shell 1610 .

[0186] in addition, Fig.16 The individual filters are only shown schematically, without showing their positions within the purification device 1600 .

[0187] In this way, the filters are stacked, the longer the filtration path is, the better the purification effect is. When the up and down adjustment mechanism is controlled to make the inner shell higher, the air inlet at the bottom end of the inner shell side first absorbs a large amount of small-sized particles at the upper air intake port, and after a period of time, it transfers to the lower air intake port to absorb large-sized particles. When used in conjunction with the air inlet at the bottom, the purification effect is better.

[0188] In the embodiment of the present invention, there may be a preset space between the second filter screen and the third filter screen. In this way, the second filter screen and the third filter screen are not tightly connected, forming a movable space, so that there is a gap between the filter screens, which can make the purification space better.

[0189] In an embodiment of the present invention, a lighting lamp may be provided at the air outlet and the air inlet, and the length of the lighting lamp is consistent with the length of the corresponding air inlet and the air outlet.

[0190] In this way, the movement of particles can be clearly seen under the illumination of light, and the comparison between the particles at the air inlet and the particles at the air outlet can be visualized, which has a better purification effect. At the same time, it can become a lighting lamp at night. Of course, the light color and light length can be changed, and the user experience will be better when combined with music in entertainment mode.

[0191] In the embodiment of the present invention, the purification device 1600 can be used for household, commercial or public use.

[0192] For example, the purification device 1600 can be used in a home environment, or in a commercial environment such as an office, an office building, a shopping mall, or a public environment such as a school.

[0193] It can be seen from the above embodiments that since the purification equipment is controlled according to the concentration distribution of particles of different particle sizes in the indoor space, targeted control can be performed on particles of different particle sizes, thereby improving the purification efficiency and speed, and achieving a good purification effect efficiently and quickly.

[0194] The above devices and methods of the embodiments of the present invention can be implemented by hardware, or by hardware combined with software.
