Technical Field

[0001] The present invention relates to the technical field of air purification, and in particular to an air duct structure, an air purification device and a control method and a control device thereof. Background Art

[0002] With the acceleration of industrialization and the deepening of urbanization, air pollution has become increasingly prominent, especially indoor air pollution, which poses a serious threat to people's health. Among them, odor is particularly common, which not only affects the comfort of living and working environment, but also may cause respiratory diseases.

[0003] Air purifiers can remove odors from the air, and the air duct design of air purifiers has an important impact on airflow control and purification efficiency. In related technologies, the cross-sectional size of the air duct of air purifiers is fixed and cannot adapt to the requirements of different pollution levels and airflow speeds. Summary of the invention

[0004] In view of this, the present invention provides an air duct structure, an air purification device and a control method and a control device thereof to solve the problem that the air purifier in the related art cannot adapt to different pollution levels and air flow speeds.

[0005] In a first aspect, the present invention provides an air duct structure, comprising:

[0006] Fix the duct wall;

[0007] A movable air duct wall, wherein the movable air duct wall and the fixed air duct wall enclose an air duct suitable for air to pass through, and the air duct has an air inlet end and an air outlet end;

[0008] The driving structure is connected to the movable air duct wall and is used to drive the movable air duct wall to move so as to adjust the area of ​​the air inlet end.

[0009] Beneficial effects: The movable air duct wall is movable, and the driving structure can drive the movable air duct wall to move so as to adjust the area of ​​the air inlet end. By adjusting the area of ​​the air inlet end, the amount of air entering the air duct can be adjusted. When the air duct structure is applied to an air purification device, when the pollution level is high, the area of ​​the air inlet end can be increased to improve the air extraction capacity and quickly remove the odor; when the pollution level is low, the area of ​​the air inlet end can be reduced, which can reduce the power demand of the fan, reduce energy consumption and operating costs, and achieve energy conservation and emission reduction. Therefore, the flexibility and adaptability of the air purification device can be enhanced, so that it can maintain efficient operation in different environments and working conditions.

[0010] When the air duct structure is applied to an air purification device, the air flow rate and purification efficiency can be optimized by adjusting the area of ​​the air inlet end of the air duct.

[0011] In an optional embodiment, one end of the movable air duct wall is hinged to the fixed air duct wall, and two sides thereof are in contact with the fixed air duct wall, and the driving structure is used to drive the movable air duct wall to rotate.

[0012] Beneficial effects: One end of the movable air duct wall is hinged to the fixed air duct wall, and both sides are in contact with the fixed air duct wall. The driving structure is used to drive the movable air duct wall to rotate. By rotating the movable air duct wall, not only the area of ​​the air inlet end of the air duct can be adjusted, but also the cross-sectional area inside the air duct can be adjusted together. The air volume passing through the air duct can be adjusted as a whole, and only the movable air duct wall needs to be driven from one end, which is easier to control. In addition, the air duct enclosed by the movable air duct wall and the fixed air duct wall is horn-shaped, and the area of ​​the air inlet end is larger than the area of ​​the air outlet end. This will increase the flow rate of air after entering the air duct, thereby improving the purification efficiency.

[0013] In an optional embodiment, the movable air duct wall cooperates with the fixed air duct wall via a guide structure, and the guide structure is used to guide the rotation direction of the movable air duct wall.

[0014] Beneficial effect: By setting a guide structure, the guide structure is used to guide the rotation direction of the movable air duct wall, thereby ensuring that the movable air duct wall rotates smoothly.

[0015] In an optional embodiment, the guide structure includes:

[0016] A guide rail, arranged on the fixed air duct wall;

[0017] The protrusions are protrudingly arranged on both sides of the movable air duct wall, and the protrusions are slidably arranged on the guide rails.

[0018] Beneficial effect: When the driving structure drives the movable air duct wall to rotate, the protrusions on both sides of the movable air duct wall slide along the guide rails, and the guide rails and the protrusions cooperate to guide the rotation direction of the movable air duct wall.

[0019] In an optional embodiment, two movable air duct walls are symmetrically provided.

[0020] Beneficial effect: Since two movable air duct walls are symmetrically arranged, the area of ​​the air inlet end of the air duct can be quickly adjusted by synchronously rotating the two movable air duct walls.

[0021] In an optional embodiment, two fixed air duct walls are symmetrically arranged, and the air duct structure further includes a connecting wall panel connecting the two ends of the two fixed air duct walls, the connecting wall panel and the fixed air duct walls form an outer frame, and the movable air duct wall is located in the outer frame.

[0022] Beneficial effects: the connecting wall plate and the fixed air duct wall form an outer frame, the movable air duct wall is located inside the outer frame, the appearance of the air duct structure is overall beautiful, and it is easy to install inside the air purification device.

[0023] In the second aspect, the present invention also provides an air purification device, comprising the above-mentioned air duct structure and a deodorization module, wherein the deodorization module is arranged downstream of the air duct structure, and the air purification device has an air inlet and an air outlet, wherein the air inlet is connected to the air inlet end, and the air outlet is arranged downstream of the deodorization module.

[0024] Beneficial effects: After the air enters the air purification device through the air inlet, it enters the air duct through the air inlet end of the air duct structure, then flows through the deodorization module, removes the odor of the air and then flows out from the air outlet. The air purification device can remove the odor in the air. And because the movable air duct wall of the air duct structure is movable, the driving structure can drive the movable air duct wall to move so as to adjust the area of ​​the air inlet end. By adjusting the area of ​​the air inlet end, the amount of air entering the air duct can be adjusted. When the pollution level is high, the area of ​​the air inlet end can be increased to improve the air extraction capacity and quickly remove the odor; when the pollution level is low, the area of ​​the air inlet end can be reduced, which can reduce the power demand of the fan, reduce energy consumption and operating costs, and achieve energy conservation and emission reduction. Therefore, the flexibility and adaptability of the air purification device can be enhanced, so that it can maintain efficient operation in different environments and working conditions.

[0025] In an optional embodiment, the air purification device also includes a controller, the air inlet is provided with a first odor detection structure, the air outlet is provided with a second odor detection structure, and the controller is communicatively connected with the first odor detection structure, the second odor detection structure and the driving structure.

[0026] Beneficial effect: by setting a first odor detection structure at the air inlet, the first odor detection structure can detect the odor value at the air inlet, and setting a second odor detection structure at the air outlet, the second odor detection structure can detect the odor value at the air outlet, so the odor removal rate can be calculated according to the odor value at the air inlet and the odor value at the air outlet, so as to determine whether it is necessary to adjust the area of ​​the air inlet end and whether to increase or decrease the area of ​​the air inlet end according to the odor removal rate. The controller is communicated with the first odor detection structure, the second odor detection structure and the driving structure, and can realize automatic adjustment of the cross-sectional area of ​​the air duct, so as to enhance the flexibility and adaptability of the air purification device, so that it can maintain efficient operation under different environments and working conditions.

[0027] In a third aspect, the present invention further provides a control method for an air purification device, which is applied to the air purification device, and the control method comprises:

[0028] Obtain the odor value at the air inlet and the odor value at the air outlet;

[0029] Calculate the odor removal rate based on the odor value at the air inlet and the odor value at the air outlet;

[0030] Determining whether the odor removal rate is less than a first set value;

[0031] If so, the driving structure is controlled to operate according to the odor removal rate to adjust the area of ​​the air inlet end.

[0032] Beneficial effect: By obtaining the odor value at the air inlet and the odor value at the air outlet, the odor removal rate is calculated according to the odor value at the air inlet and the odor value at the air outlet. If the odor removal value is less than the first set value, it means that the odor removal rate has not reached the ideal value. Therefore, the driving structure is controlled to work according to the odor removal rate to adjust the area of ​​the air inlet end, so that the cross-sectional area of ​​the air duct can be automatically adjusted, which can enhance the flexibility and adaptability of the air purification device, so that it can maintain efficient operation in different environments and working conditions.

[0033] In an optional embodiment, controlling the driving structure to work according to the odor removal rate to adjust the area of ​​the air inlet end includes:

[0034] Determining whether the odor removal rate is less than a second set value;

[0035] If so, the control driving structure works to adjust the movable air duct wall to a first position. When the movable air duct wall is in the first position, the area of ​​the air inlet end reaches a maximum.

[0036] Beneficial effect: If the odor removal rate is less than the second set value, it means that the odor removal rate is low. Therefore, the control driving structure is operated to adjust the movable air duct wall to the first position to maximize the area of ​​the air inlet end, thereby improving the exhaust capacity and quickly removing the odor.

[0037] In an optional embodiment, the controlling the driving structure to operate according to the odor removal rate to adjust the area of ​​the air inlet end further includes:

[0038] Determining whether the odor removal rate is greater than or equal to a second preset value and less than a third preset value;

[0039] If so, the control driving structure works to adjust the movable air duct wall to a second position, and when the movable air duct wall is in the second position, the area of ​​the air inlet end is smaller than the area of ​​the air inlet end when the movable air duct wall is in the first position.

[0040] Beneficial effect: If the odor removal rate is greater than or equal to the second set value and less than the third preset value, the odor removal rate is not very low, and the control driving structure works to adjust the movable air duct wall to the second position, which can further optimize the air flow rate and purification efficiency.

[0041] In an optional embodiment, the controlling the driving structure to operate according to the odor removal rate to adjust the area of ​​the air inlet end further includes:

[0042] Determining whether the odor removal rate is greater than or equal to a third preset value and less than a first preset value;

[0043] If so, the control driving structure works to adjust the movable air duct wall to a third position, and when the movable air duct wall is in the third position, the area of ​​the air inlet end is smaller than the area of ​​the air inlet end when the movable air duct wall is in the second position.

[0044] Beneficial effect: If the odor removal rate is greater than or equal to the third set value and less than the first preset value, it means that the odor removal rate is relatively high. Therefore, the driving structure is controlled to adjust the movable air duct wall to the third position, which can reduce the area of ​​the air inlet end, reduce the power demand of the fan, reduce energy consumption and operating costs, and achieve energy conservation and emission reduction.

[0045] In a fourth aspect, the present invention further provides a control device for an air purification device, which is applied to the air purification device, and the control device comprises:

[0046] An acquisition module, used to acquire the odor value at the air inlet and the odor value at the air outlet;

[0047] A calculation module, used to calculate the odor removal rate according to the odor value at the air inlet and the odor value at the air outlet;

[0048] A judging module, used to judge whether the odor removal rate is less than a first set value;

[0049] The control module is used to control the driving structure to operate according to the odor removal rate to adjust the area of ​​the air inlet end when the odor removal rate is less than a first set value. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0066] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0067] With the acceleration of industrialization and the deepening of urbanization, air pollution has become increasingly prominent, especially indoor air pollution, which poses a serious threat to people's health. Among them, odor is particularly common, which not only affects the comfort of living and working environment, but also may cause respiratory diseases.

[0068] The air purifier can remove odors from the air, and the design of the air duct 100 of the air purifier has an important influence on airflow control and purification efficiency. In the related art, the cross-sectional size of the air duct 100 of the air purifier is fixed, which cannot meet the requirements of different pollution levels and airflow speeds.

[0069] Combine the following Figures 1 to 13 , describing an embodiment of the present invention.

[0070] According to an embodiment of the present invention, in a first aspect, there is provided an air duct structure 1, comprising a fixed air duct wall 101, a movable air duct wall 102 and a driving structure.

[0071] Among them, the movable air duct wall 102 and the fixed air duct wall 101 form an air duct 100 suitable for air to pass through, and the air duct 100 has an air inlet end and an air outlet end; the driving structure is connected to the movable air duct wall 102, and is used to drive the movable air duct wall 102 to move to adjust the area of ​​the air inlet end.

[0072] In this embodiment, the movable air duct wall 102 is movably arranged, and the driving structure can drive the movable air duct wall 102 to move so as to adjust the area of ​​the air inlet end. By adjusting the area of ​​the air inlet end, the amount of air entering the air duct 100 can be adjusted. When the air duct structure 1 is applied to an air purification device, when the pollution level is high, the area of ​​the air inlet end can be increased to improve the air extraction capacity and quickly remove the odor; when the pollution level is low, the area of ​​the air inlet end can be reduced, which can reduce the power demand of the fan, reduce energy consumption and operating costs, and achieve energy conservation and emission reduction. Therefore, the flexibility and adaptability of the air purification device can be enhanced, so that it can maintain efficient operation in different environments and working conditions.

[0073] When the air duct structure 1 is applied to an air purification device, the air flow rate and purification efficiency can be optimized by adjusting the area of ​​the air inlet end of the air duct 100 .

[0074] It should be noted that, since the movable air duct wall 102 is movably arranged, when the area of ​​the air inlet end is adjusted, the cross-sectional area of ​​the air duct 100 changes along with the overall area of ​​the air inlet end.

[0075] In one embodiment, one end of the movable air duct wall 102 is hinged to the fixed air duct wall 101 , and both sides are in contact with the fixed air duct wall 101 , and the driving structure is used to drive the movable air duct wall 102 to rotate.

[0076] In this embodiment, one end of the movable air duct wall 102 is hinged to the fixed air duct wall 101, and both sides are in contact with the fixed air duct wall 101. The driving structure is used to drive the movable air duct wall 102 to rotate. By rotating the movable air duct wall 102, not only the area of ​​the air inlet end of the air duct 100 can be adjusted, but also the cross-sectional area inside the air duct 100 can be adjusted together, so that the air volume passing through the air duct 100 can be adjusted as a whole, and only the movable air duct wall 102 needs to be driven from one end, which is more convenient for control. In addition, the air duct 100 enclosed by the movable air duct wall 102 and the fixed air duct wall 101 is horn-shaped, and the area of ​​the air inlet end is larger than the area of ​​the air outlet end, which will increase the flow rate of air after entering the air duct 100, thereby improving the purification efficiency.

[0077] Specifically in one embodiment, a rotating shaft 1021 is provided on both sides of the first end of the movable air duct wall 102 , and the rotating shaft 1021 is hinged to the fixed air duct wall 101 . The driving structure drives the movable air duct wall 102 to rotate by driving the rotating shaft 1021 to rotate.

[0078] Specifically in one embodiment, the driving structure includes a driving motor, a driving gear and a driven gear. The driving motor is connected to the driving gear, and the rotating shaft 1021 is fixedly connected to the driven gear. The driven gear is meshed with the driving gear. The driving motor rotates to drive the driving gear to rotate, and the driving gear drives the driven gear to rotate and then drives the rotating shaft 1021 to rotate.

[0079] Specifically in one embodiment, the driving structure may only include a driving motor, and the output shaft of the driving motor is fixedly connected to the rotating shaft 1021 .

[0080] Specifically in one embodiment, a rotating shaft 1021 is provided on both sides of the first end of the movable air duct wall 102, the rotating shaft 1021 is hinged to the fixed air duct wall 101, and the driving structure drives the second end of the movable air duct wall 102 to rotate. In this embodiment, the driving structure may include a driving cylinder, the cylinder body of the driving cylinder is arranged on the fixed air duct wall 101, and the push rod end of the driving cylinder is hinged to the second end of the movable air duct wall 102.

[0081] In a replaceable embodiment, the movable air duct wall 102 is movably arranged as a whole between two opposite fixed air duct walls 101. When the movable air duct wall 102 moves, the air inlet and air outlet areas of the air duct 100 surrounded by the movable air duct wall 102 and the fixed air duct wall 101 simultaneously increase or decrease. In this embodiment, the driving structure is used to drive the movable air duct wall 102 to translate. The driving structure may include a motor, a gear, and a rack. The rack is connected to the movable air duct wall 102. The output shaft of the motor is connected to the gear. The gear is meshed with the rack. The motor drives the gear to rotate. The gear is meshed with the rack, thereby driving the rack to move, and then driving the movable air duct wall 102 to translate. The driving structure may be symmetrically provided with two groups. Alternatively, the driving structure includes a motor and a screw nut mechanism. The motor drives the screw to rotate. The nut is connected to the movable air duct wall 102. The screw rotation drives the nut to move, thereby driving the movable air duct wall 102 to translate. Alternatively, the driving structure includes a cylinder, the push rod end of the cylinder is connected to the movable air duct wall 102, and at least two cylinders are provided to drive the movable air duct wall 102 to translate.

[0082] For the embodiment in which the movable air duct wall 102 is movably disposed as a whole between two opposite fixed air duct walls 101, the movable air duct wall 102 may be disposed obliquely between the two opposite fixed air duct walls 101, or may be disposed parallel to the air inlet direction between the two opposite fixed air duct walls 101. Preferably, the movable air duct wall 102 is disposed obliquely between the two opposite fixed air duct walls 101, so that the air duct 100 enclosed by the movable air duct wall 102 and the fixed air duct wall 101 is trumpet-shaped, and the air inlet end area is larger than the air outlet end area, which will increase the flow rate of air after entering the air duct 100, thereby improving the purification efficiency.

[0083] In one embodiment, the movable air duct wall 102 cooperates with the fixed air duct wall 101 via a guide structure, and the guide structure is used to guide the rotation direction of the movable air duct wall 102 .

[0084] In this embodiment, a guide structure is provided to guide the rotation direction of the movable air duct wall 102 , thereby ensuring smooth rotation of the movable air duct wall 102 .

[0085] Specifically in one embodiment, a rotating shaft 1021 is provided on both sides of the first end of the movable air duct wall 102, and the rotating shaft 1021 is hinged to the fixed air duct wall 101. The driving structure drives the movable air duct wall 102 to rotate by driving the rotating shaft 1021 to rotate, and the guide structure guides the rotation direction of the movable air duct wall 102.

[0086] In one embodiment, the guide structure includes a guide rail 1011 and a protrusion 1022. The guide rail 1011 is disposed on the fixed air duct wall 101; the protrusion 1022 is protrudingly disposed on both sides of the movable air duct wall 102, and the protrusion 1022 is slidably disposed on the guide rail 1011.

[0087] In this embodiment, when the driving structure drives the movable air duct wall 102 to rotate, the protrusions 1022 on both sides of the movable air duct wall 102 slide along the guide rails 1011 , and the guide rails 1011 and the protrusions 1022 cooperate to guide the rotation direction of the movable air duct wall 102 .

[0088] As specifically shown in the figure, the guide rail 1011 is arc-shaped.

[0089] In one embodiment, two movable air duct walls 102 are symmetrically provided.

[0090] In this embodiment, since two movable air duct walls 102 are symmetrically provided, the synchronous rotation of the two movable air duct walls 102 can quickly adjust the area of ​​the air inlet end of the air duct 100 .

[0091] Specifically in one embodiment, Figures 1 to 4 As shown, the movable air duct wall 102 is symmetrically arranged in the up and down directions.

[0092] Specifically in one embodiment, a rotating shaft 1021 is provided on both sides of the first end of the movable air duct wall 102, and the rotating shaft 1021 is hinged to the fixed air duct wall 101. The driving structure drives the movable air duct wall 102 to rotate by driving the rotating shaft 1021 to rotate. Since two movable air duct walls 102 are symmetrically provided, the two movable air duct walls 102 need to rotate synchronously. The driving structure can be symmetrically provided with two groups, or the two movable air duct walls 102 can be driven to rotate at the same time by one group of driving structures.

[0093] When two movable air duct walls 102 are driven to rotate simultaneously through a set of driving structures, the driving structure may include a motor, a driving gear, and a symmetrically arranged driven gear or gear set. The symmetrically arranged driven gears or gear sets are respectively connected to the rotating shafts 1021 of the movable air duct walls 102, so that the two movable air duct walls 102 can be driven to rotate simultaneously by one motor.

[0094] In one embodiment, two fixed air duct walls 101 are symmetrically arranged, and the air duct structure 1 further includes a connecting wall plate 103 connecting the two ends of the two fixed air duct walls 101. The connecting wall plate 103 and the fixed air duct walls 101 form an outer frame, and the movable air duct wall 102 is located in the outer frame.

[0095] In this embodiment, the connecting wall plate 103 and the fixed air duct wall 101 form an outer frame, and the movable air duct wall 102 is located inside the outer frame. The air duct structure 1 has an overall beautiful appearance and is easy to install inside the air purification device.

[0096] Specific as Figure 1 and Figure 5 , Figure 6 As shown, two connecting wall panels 103 are spaced apart and connected to the same end of the fixed air duct wall 101, so that the overall weight of the air duct structure 1 can be reduced, and the air duct structure 1 can be fixed inside the air purification device through the connecting wall panels 103.

[0097] Specifically in one embodiment, the fixed air duct wall 101 and the movable air duct wall 102 are both rectangular plates.

[0098] In one embodiment, the movable air duct wall 102 may be of an irregular shape, for example, formed by splicing two rectangular plates, wherein one rectangular plate is arranged obliquely, and the other rectangular plate is arranged horizontally.

[0099] According to an embodiment of the present invention, in a second aspect, an air purification device is provided, such as Figure 7 As shown, it includes the air duct structure 1 and the deodorization module 2 provided in the above embodiment. The deodorization module 2 is arranged downstream of the air duct structure 1. The air purification device has an air inlet 3 and an air outlet 4. The air inlet 3 is connected to the air inlet end, and the air outlet 4 is arranged downstream of the deodorization module 2.

[0100] In this embodiment, after the air enters the air purification device through the air inlet 3, it enters the air duct 100 through the air inlet end of the air duct structure 1, and then flows through the deodorization module 2, removes the odor of the air and flows out from the air outlet 4. The air purification device can remove the odor in the air. And because the movable air duct wall 102 of the air duct structure 1 is movable, the driving structure can drive the movable air duct wall 102 to move so as to adjust the area of ​​the air inlet end, and the air flow entering the air duct 100 can be adjusted by adjusting the area of ​​the air inlet end. When the pollution level is high, the area of ​​the air inlet end can be increased to improve the air extraction capacity and quickly remove the odor; when the pollution level is low, the area of ​​the air inlet end can be reduced, which can reduce the power demand of the fan, reduce energy consumption and operating costs, and achieve energy conservation and emission reduction. Therefore, the flexibility and adaptability of the air purification device can be enhanced, so that it can maintain efficient operation in different environments and working conditions.

[0101] In one embodiment, the deodorization module 2 specifically includes a plasma module 201. The plasma module 201 can generate a large amount of plasma when in operation. Plasma is a highly ionized gas containing a large amount of active substances, such as free radicals (OH·, O·), ozone (O) and hydrogen peroxide (HO), etc. These active particles have strong oxidizing ability and can react with odor molecules to decompose them into harmless small molecules, such as water and carbon dioxide, etc. When the odor molecules in the space pass through the discharge area of ​​the plasma module 201, the odor can be effectively removed to protect human health.

[0102] Specifically in one embodiment, Fig.11 and Fig.12 The deodorization module 2 further includes an upper cover plate 202 and a lower cover plate 203 . The plasma module 201 is disposed in a channel surrounded by the upper cover plate 202 and the lower cover plate 203 . The channel has an inlet and an outlet, and the inlet is connected to the air outlet end of the air duct 100 .

[0103] In one embodiment, the air purification device also includes a controller, the air inlet 3 is provided with a first odor detection structure 5, the air outlet 4 is provided with a second odor detection structure 6, and the controller is communicatively connected with the first odor detection structure 5, the second odor detection structure 6 and the driving structure.

[0104] In this embodiment, a first odor detection structure 5 is provided at the air inlet 3, which can detect the odor value at the air inlet 3; a second odor detection structure 6 is provided at the air outlet 4, which can detect the odor value at the air outlet 4. Therefore, the odor removal rate can be calculated based on the odor value at the air inlet 3 and the odor value at the air outlet 4, so that it is possible to determine whether it is necessary to adjust the area of ​​the air inlet end and whether it is necessary to increase or decrease the area of ​​the air inlet end according to the odor removal rate. The controller is communicatively connected with the first odor detection structure 5, the second odor detection structure 6 and the driving structure, so as to realize automatic adjustment of the cross-sectional area of ​​the air duct 100, thereby enhancing the flexibility and adaptability of the air purification device, so that it can maintain efficient operation under different environments and working conditions.

[0105] According to an embodiment of the present invention, in a third aspect, a control method for an air purification device is provided, which is applied to an air purification device such as Fig.13 As shown, the control method includes:

[0106] Obtain the odor value at the air inlet 3 and the odor value at the air outlet 4;

[0107] The odor removal rate is calculated based on the odor value at the air inlet 3 and the odor value at the air outlet 4;

[0108] Determining whether the odor removal rate is less than a first set value;

[0109] If so, the driving structure is controlled to operate according to the odor removal rate to adjust the area of ​​the air inlet end.

[0110] In this embodiment, by obtaining the odor value at the air inlet 3 and the odor value at the air outlet 4, the odor removal rate is calculated according to the odor value at the air inlet 3 and the odor value at the air outlet 4. If the odor removal value is less than the first set value, it means that the odor removal rate has not reached the ideal value. Therefore, the driving structure is controlled to work according to the odor removal rate to adjust the area of ​​the air inlet end, so that the cross-sectional area of ​​the air duct 100 can be automatically adjusted, which can enhance the flexibility and adaptability of the air purification device so that it can maintain efficient operation under different environments and working conditions.

[0111] Specifically in one embodiment, the first setting value is 90%. It should be noted that this embodiment does not limit the first setting value, and the user can set it according to needs.

[0112] Specifically in one embodiment, if the odor removal rate is greater than or equal to the first set value, the driving structure does not need to work, and the movable air duct wall 102 can remain in the current position. Thereafter, the odor value at the air inlet 3 and the odor value at the air outlet 4 are re-obtained at every preset time interval until the user turns off the device.

[0113] Specifically, the odor value at the air inlet 3 and the odor value at the air outlet 4 may be re-obtained every 10 minutes until the user turns off the device.

[0114] In one embodiment, controlling the driving structure to work according to the odor removal rate to adjust the area of ​​the air inlet end includes:

[0115] Determining whether the odor removal rate is less than a second set value;

[0116] If so, the driving structure is controlled to work so as to adjust the movable air duct wall 102 to the first position. When the movable air duct wall 102 is in the first position, the area of ​​the air inlet end reaches the maximum.

[0117] In this embodiment, if the odor removal rate is less than the second set value, it means that the odor removal rate is low, so the control driving structure works to adjust the movable air duct wall 102 to the first position, such as Figure 8 As shown, the area of ​​the air inlet end is maximized, thereby improving the air extraction capacity and quickly removing odors.

[0118] Specifically in one embodiment, the second setting value is 50%. It should be noted that this embodiment does not limit the second setting value, and the user can set it according to needs.

[0119] In one embodiment, controlling the driving structure to work according to the odor removal rate to adjust the area of ​​the air inlet end further includes:

[0120] Determining whether the odor removal rate is greater than or equal to a second preset value and less than a third preset value;

[0121] If so, the control driving structure works to adjust the movable air duct wall 102 to the second position. When the movable air duct wall 102 is in the second position, the area of ​​the air inlet end is smaller than the area of ​​the air inlet end when the movable air duct wall 102 is in the first position.

[0122] In this embodiment, if the odor removal rate is greater than or equal to the second set value and less than the third preset value, the odor removal rate is not very low, and the control driving structure works to adjust the movable air duct wall 102 to the second position, such as Fig. 9 As shown, the air flow rate and purification efficiency can be further optimized.

[0123] Specifically in one embodiment, the third setting value is 70%. It should be noted that this embodiment does not limit the third setting value, and the user can set it according to needs.

[0124] In one embodiment, the driving structure is controlled to work according to the odor removal rate to adjust the area of ​​the air inlet end, and further includes:

[0125] Determining whether the odor removal rate is greater than or equal to a third preset value and less than a first preset value;

[0126] If so, the control driving structure works to adjust the movable air duct wall 102 to the third position. When the movable air duct wall 102 is in the third position, the area of ​​the air inlet end is smaller than the area of ​​the air inlet end when the movable air duct wall 102 is in the second position.

[0127] In this embodiment, if the odor removal rate is greater than or equal to the third set value and less than the first preset value, it means that the odor removal rate is relatively high, so the control driving structure works to adjust the movable air duct wall 102 to the third position, such as Fig.10 As shown, the area of ​​the air inlet end can be reduced, the power demand of the fan can be reduced, the energy consumption and operating costs can be reduced, and energy conservation and emission reduction can be achieved.

[0128] Specifically in one embodiment, after the driving structure is controlled to work according to the odor removal rate to adjust the area of ​​the air inlet, the odor value at the air inlet 3 and the odor value at the air outlet 4 are re-obtained at every preset time interval until the user turns off the device.

[0135] Specifically in one embodiment, the first setting value is 90%. It should be noted that this embodiment does not limit the first setting value, and the user can set it according to needs.

[0136] Specifically in one embodiment, if the odor removal rate is greater than or equal to the first set value, the driving structure does not need to work, and the movable air duct wall 102 can remain in the current position. Thereafter, the acquisition module re-acquires the odor value at the air inlet 3 and the odor value at the air outlet 4 at a preset time interval until the user turns off the device.

When the movable air duct wall 102 is in the first position, the area of ​​the air inlet end reaches the maximum.

[0141] In this embodiment, if the odor removal rate is less than the second set value, it means that the odor removal rate is low. Therefore, the first control submodule controls the driving structure to adjust the movable air duct wall 102 to the first position to maximize the area of ​​the air inlet end, thereby improving the exhaust capacity and quickly removing the odor.

[0142] Specifically in one embodiment, the second setting value is 50%. It should be noted that this embodiment does not limit the second setting value, and the user can set it according to needs.

[0143] In one embodiment, the control module further includes:
