[0061] Please also read Figure 1 and Figure 2 The present application provides a fresh air device, which includes an air duct structure 1. The air duct structure 1 includes a shell 80, a first heat exchanger 30, a second heat exchanger 40, at least one adjustment component, a first fan 10 and a second fan 20. The shell 80 includes a shell body 81, a first air shell 60 and a second air shell 70, and the first air shell 60 and the second air shell 70 are both connected to the shell body 81. Both the first heat exchanger 30 and the second heat exchanger 40 are connected to the shell body 81 and are located between the first air shell 60 and the second air shell 70. The first air shell 60, the first heat exchanger 30 and the second air shell 70 are jointly constructed to form an air inlet flow channel. The first air shell 60, the second heat exchanger 40 and the second air shell 70 are jointly constructed to form an air outlet flow channel independent of the air inlet flow channel. At least one of the air inlet flow channel and the air outlet flow channel has at least one adjustment area. At least one adjustment component is connected to the shell 80 and is correspondingly arranged in each adjustment area. Each adjustment component is used to collect the wind pressure value of the current adjustment area, and adjust the wind pressure of the adjustment area when the wind pressure value of the adjustment area is not equal to the corresponding set threshold value, until the wind pressure value of the adjustment area is equal to the corresponding set threshold value. The first fan 10 and the second fan 20 are both connected to the shell body 81, and the first fan 10 is used to drive the outdoor airflow to flow through the interior of the first wind shell 60, the first heat exchanger 30 and the outer surface of the second wind shell 70 in sequence when the air is taken in. The second fan 20 is used to drive the indoor airflow to flow through the interior of the second wind shell 70, the second heat exchanger 40 and the outer surface of the first wind shell 60 in sequence when the air is discharged. The first heat exchanger 30 is used to perform heat exchange on the outdoor airflow flowing through it during the air intake process. The second heat exchanger 40 is used to perform heat exchange on the indoor airflow flowing through it during the air discharge process.

[0062] Specifically, the housing body 81 has a receiving cavity 812, and the housing body 81 also has a first air inlet 814, a first air outlet 816, a second air inlet 818, and a second air outlet 819, which are all connected to the receiving cavity 812. The air inlet channel is connected between the first air inlet 814 and the first air outlet 816, and the air outlet channel is connected between the second air inlet 818 and the second air outlet 819. The first fan 10, the second fan 20, the first heat exchanger 30, and the second heat exchanger 40 are all received in the receiving cavity 812. When the fresh air device is working, the indoor air flow and the outdoor air flow are exchanged, that is, the outdoor air flow flows into the room through the first air inlet 814, the air inlet duct and the first air outlet 816 in sequence. At the same time, the indoor air flow flows into the outdoors through the second air inlet 818, the air outlet duct and the second air outlet 819 in sequence.

[0063] In the traditional air duct structure 1, after the air inlet flow channel and the air outlet flow channel are formed, the space inside the air inlet flow channel and the air outlet flow channel cannot be changed. When there is an area with abnormal wind pressure in the space of at least one of the air inlet flow channel and the air outlet flow channel, turbulence is likely to form in the area. In this way, the wind loss in the area increases, which in turn causes the air intake and air outlet of the fresh air device to decrease, and the air supply efficiency is low. Among them, the air intake volume refers to the air volume of the outdoor air flow flowing into the room per unit time, and the air outlet volume refers to the air volume of the indoor air flow flowing out to the outdoors per unit time. When there is a large wind loss, the air intake and air outlet of the fresh air device will be appropriately reduced. The air supply efficiency includes the efficiency of the fresh air device in supplying air to the room and the efficiency of supplying air to the outdoors. If the air intake and air outlet of the fresh air device are reduced, the air supply efficiency will also be reduced.

[0064] In the present application, each adjustment component is used to collect the wind pressure value of the current adjustment area, and adjust the wind pressure of the adjustment area when the wind pressure value of the adjustment area is not equal to the set threshold value corresponding thereto, until the wind pressure value of the adjustment area is equal to the set threshold value corresponding thereto. It can be seen that by setting the adjustment component, when the wind pressure in each adjustment area is abnormal, the adjustment component can adjust the adjustment area so that the wind pressure value in the adjustment area is equal to the set threshold value corresponding thereto. In this way, the formation of turbulence can be prevented, and the wind loss of the outdoor airflow passing through the air inlet duct and / or the indoor airflow passing through the air outlet duct can be reduced, so the air supply efficiency of the air duct structure 1 can be effectively improved.

[0065] Optionally, there may be one adjustment area, and one adjustment area may be located in the air inlet channel or in the air outlet channel. Alternatively, there may be at least two adjustment areas, wherein at least one adjustment area is located in the air inlet channel and at least one adjustment area is located in the air outlet channel. An adjustment component is provided in each adjustment area, and each adjustment area corresponds to a set threshold. Each adjustment component is used to adjust the wind pressure in the adjustment area when an abnormality occurs in the wind pressure value in the corresponding adjustment area (that is, when the wind pressure value in the adjustment area is not equal to the corresponding set threshold), so that the wind pressure value in the adjustment area is equal to the corresponding set threshold. Specifically, the set threshold corresponding to each adjustment area may be the same or different, and needs to be set according to actual conditions.

[0066] Among them, each adjustment component includes a collecting part and an adjusting part 90. The collecting part is used to collect the wind pressure value of the current adjustment area. When the wind pressure value of the current adjustment area is not equal to the set threshold value corresponding to it, the adjusting part 90 adjusts the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the set threshold value corresponding to it.

[0067] Specifically, the air duct structure 1 further includes a controller, which is electrically connected to the collecting component and the adjusting component 90 in each adjusting component. Each collecting component sends the collected wind pressure value to the controller, and the controller and the adjusting component 90 corresponding to each collecting component work according to the wind pressure value collected by each collecting component. In this way, the automation of the air duct structure 1 can be effectively improved.

[0068] In some embodiments, the outdoor airflow entering the air inlet flow channel flows sequentially through the interior of the first air shell 60, the first heat exchanger 30, and the outer surface of the second air shell 70. In the air inlet flow channel, when the adjustment area is set on the first air shell 60, the adjustment member 90 in the adjustment area adjusts the flatness of the inner surface of the first air shell 60 according to the wind pressure value of the collection member. The inner surface of the first air shell 60 is defined as the first inner surface 63, that is, when all the adjustment areas are located inside the first air shell 60, each collection member is used to collect the wind pressure value of the corresponding adjustment area. When the wind pressure value of any adjustment area is not equal to the set threshold value corresponding to the adjustment area, the adjustment member 90 corresponding to the adjustment area adjusts the flatness of the first inner surface 63 defining the adjustment area so that the wind pressure value in the adjustment area is equal to the set threshold value. When the adjustment area is set on the second air shell 70, the adjustment member 90 in the adjustment area adjusts the flatness of the outer surface of the second air shell 70 according to the wind pressure value of the collection member. That is to say, when all the adjustment areas are located outside the second wind shell 70, each collecting component is used to collect the wind pressure value of the corresponding adjustment area. When the wind pressure value of any adjustment area is not equal to the set threshold value corresponding to the adjustment area, the adjustment component 90 corresponding to the adjustment area adjusts the flatness of the outer surface of the second wind shell 70 that defines the adjustment area, so that the wind pressure value in the adjustment area is equal to the set threshold value.

[0069] In one embodiment, in the air inlet flow channel, the main reason for the abnormal wind pressure value in any adjustment area is that the surface defining the adjustment area is uneven. If the wind pressure value of a single adjustment area is greater than a set threshold, it means that the adjustment area is a raised area. If the wind pressure value of a single adjustment area is less than the set threshold, it means that the adjustment area is a pit area. At this time, if the wind pressure value in the adjustment area is less than the set threshold corresponding to the adjustment area, the pit is filled so that the depression of the pit is reduced. If the wind pressure value in the adjustment area is less than the set threshold corresponding to the adjustment area, the bulge is weakened so that the protrusion of the bulge is reduced. Furthermore, the inner surface of the first wind shell 60 or the outer surface of the second wind shell 70 that defines the adjustment area can become flat, so that the wind loss during the air intake process is smaller.

[0070] Preferably, there are multiple adjustment areas, some of which are located on the inner surface of the first wind shell 60, and the remaining parts are located on the outer surface of the second wind shell 70. Therefore, during the operation of the fresh air device, the wind pressure of the parts of the air inlet flow channel defined by the first wind shell 60 and the second wind shell 70 can be adjusted, thereby reducing the formation of turbulence in the process of outdoor airflow flowing into the room.

[0071] In one embodiment, the indoor airflow entering the air outlet flow channel flows through the interior of the second air shell 70, the second heat exchanger 40, and the outer surface of the first air shell 60 in sequence. In the air outlet flow channel, when the adjustment area is set on the second air shell 70, the adjustment member 90 in the adjustment area adjusts the flatness of the inner surface of the second air shell 70 according to the wind pressure value of the collection member. That is to say, when all the adjustment areas are located inside the second air shell 70, each collection member is used to collect the wind pressure value of the corresponding adjustment area. When the wind pressure value of any adjustment area is not equal to the set threshold value corresponding to the adjustment area, the adjustment member 90 corresponding to the adjustment area adjusts the flatness of the inner surface of the second air shell 70 defining the adjustment area, so that the wind pressure value in the adjustment area is equal to the set threshold value. When the adjustment area is set on the first air shell 60, the adjustment member 90 in the adjustment area adjusts the flatness of the outer surface of the first air shell 60 according to the wind pressure value of the collection member. The outer surface of the first wind shell 60 is defined as the first outer surface 65, that is, when all the adjustment areas are located outside the first wind shell 60, each collecting component is used to collect the wind pressure value of the corresponding adjustment area, and when the wind pressure value of any adjustment area is not equal to the set threshold value corresponding to the adjustment area, the adjustment component 90 corresponding to the adjustment area adjusts the flatness of the first outer surface 65 that defines the adjustment area, so that the wind pressure value in the adjustment area is equal to the set threshold value.

[0072] Preferably, there are multiple adjustment areas, some of which are located on the inner surface of the second wind shell 70, and the remaining parts are located on the outer surface of the first wind shell 60. Therefore, during the operation of the fresh air device, the wind pressure of the parts of the air outlet flow channel defined by the first wind shell 60 and the second wind shell 70 can be adjusted, thereby reducing the formation of turbulence in the process of outdoor airflow flowing into the room.

[0073] Specifically, the adjustment method of the adjustment area in the air outlet flow channel is the same as the adjustment method of the adjustment area in the air inlet flow channel, so it will not be repeated here.

[0074] Preferably, in one embodiment, the inner surface of the first wind shell 60 has a plurality of first inner areas, all of which correspond to all of the adjustment areas on the inner surface of the first wind shell 60, each of which defines an adjustment area corresponding thereto, and all of the first inner areas are combined to form the inner surface of the first wind shell 60. The outer surface of the second wind shell 70 has a plurality of second outer areas, all of which correspond to all of the adjustment areas on the outer surface of the second wind shell 70, each of which defines an adjustment area corresponding thereto, and all of the second outer areas are combined to form the outer surface of the second wind shell 70. In addition, the inner surface of the second wind shell 70 has a plurality of second inner areas, all of which correspond to all of the adjustment areas on the inner surface of the second wind shell 70, each of which defines an adjustment area corresponding thereto, and all of the second inner areas are combined to form the inner surface of the second wind shell 70. The first wind shell 60 has a plurality of first outer areas on its outer surface, all of which correspond one-to-one to all of the adjustment areas on the outer surface of the first wind shell 60, each second outer area is defined to form a corresponding adjustment area, and all of the second outer areas are combined to form the outer surface of the second wind shell 70.

[0075] In some embodiments, the first wind shell 60 and the second wind shell 70 are both made of deformable materials, and each adjustment member 90 is used to provide an adjustment force to change the flatness of the inner and outer surfaces of the current wind shell. Specifically, taking the adjustment area located on the inner surface of the first wind shell 60 as an example, when the wind pressure value of the adjustment area is less than the set threshold, the adjustment member 90 corresponding to the adjustment area drives the adjustment area to protrude in the direction that can increase the wind pressure, so that the degree of depression of the adjustment area is weakened. When the wind pressure value of the adjustment area is greater than the set threshold, the adjustment member 90 corresponding to the adjustment area drives the adjustment area to protrude in the direction that can reduce the wind pressure, so that the protrusion of the adjustment area is weakened. Specifically, the adjustment method of the flatness of the inner surface of the first wind shell 60, the outer surface of the first wind shell 60, the inner surface of the second wind shell 70, and the outer surface of the second wind shell 70 is the same, which will not be repeated here. By adopting a method in which each adjustment member 90 is used to provide an adjustment force to change the flatness of the inner and outer surfaces of the current wind shell, the ease of adjustment can be improved, thereby making the adjustment of wind pressure simpler.

[0076] Of course, in some other embodiments, when there are pits, the flatness can be adjusted by using additional filling materials to fill the pits and by using cutting pieces to cut the protrusions.

[0077] Furthermore, both the first wind shell 60 and the second wind shell 70 are double-layer shell structures, and each adjustment member 90 is disposed between the inner layer and the outer layer of the current wind shell, and is used to adjust the flatness of the inner and outer surfaces of the current wind shell. Specifically, a first adjustment space 61 is formed between the inner layer of the first wind shell 60 and the outer layer of the first wind shell 60, and a second adjustment space is formed between the inner layer of the second wind shell 70 and the outer layer of the second wind shell 70. When adjustment areas are provided on both the first wind shell 60 and the second wind shell 70, all adjustment components corresponding to all adjustment areas on the first wind shell 60 are located in the first adjustment space 61, and are used to adjust the flatness of the inner and outer surfaces of the first wind shell 60, and all adjustment components corresponding to all adjustment areas on the second wind shell 70 are located in the second adjustment space, and are used to adjust the flatness of the inner and outer surfaces of the second wind shell 70. By setting the first wind shell 60 and the second wind shell 70 to be double-layer shell structures, all adjustment components arranged on the first wind shell 60 and the second wind shell 70 can be hidden, and each adjustment component can be prevented from contacting the indoor airflow and the outdoor airflow during the operation of the fresh air device. In other words, each adjustment component does not block the flow of the indoor airflow and the outdoor airflow, thereby preventing the formation of turbulence.

[0078] Please also read Figure 3 , Figure 4 and Figure 5 In some embodiments, each adjustment member 90 includes an elastic body 91, a base 93, a first operating body 95, and a second operating body 97. The first operating body 95 and the second operating body 97 are respectively connected to opposite ends of the base 93 through the elastic body 91 in a telescopic manner, and the first operating body 95 is connected to the inner layer of the wind shell where it is currently located, and the second operating body 97 is connected to the outer layer of the wind shell where it is currently located. Specifically, taking the adjustment area in the first wind shell 60 as an example, when the wind pressure value of any adjustment area in the first wind shell 60 is greater than the set threshold, the first operating body 95 corresponding to the adjustment area shrinks relative to the base 93, so that the protrusion of the protrusion where the adjustment area is located is reduced. When the wind pressure value of any adjustment area in the first wind shell 60 is less than the set threshold, the first operating body 95 corresponding to the adjustment area is extended relative to the base 93, so that the depression of the pit where the adjustment area is located is reduced, so that the inner surface of the first wind shell 60 has a better flatness. The second operating body 97 is used to adjust the flatness of the outer surface of the first wind shell 60, and its operation method is the same as the adjustment method of the first operating body 95, so it is not repeated here. In addition, when all adjustment areas are located on the second wind shell 70, the adjustment method of the adjustment assembly is the same as above, so it is not repeated here. By setting the first operating body 95 and the second operating body 97 to be telescopically connected to the opposite ends of the base 93 through the elastic body 91, the wind pressure adjustment operation of each adjustment area is simpler and more reliable.

[0079] It is worth mentioning that, in order to further improve the sliding stability of the operating body, a slideway capable of guiding the sliding of the operating body may be provided on the wind housing to prevent the operating body from deviating during the sliding process.

[0080] It is worth mentioning that the first operating body 95 and the second operating body 97 are respectively connected to opposite ends of the base 93 in a telescopic manner through the elastic body 91. Therefore, when the first operating body 95 and the second operating body 97 are extended and retracted relative to the base 93, the elastic body 91 can always ensure that the base 93 and the first operating body 95 and the second operating body 97 can be stably connected by its own deformation, and the elastic body 91 does not hinder the movement of the operating body relative to the base 93. Preferably, each of the first operating body 95 and the second operating body 97 is connected to the base 93 through a plurality of elastic bodies 91, so that the reliability of the connection between the first operating body 95 and the second operating body 97 and the base 93 can be improved.

[0081] Furthermore, the first operating body 95, the base 93 and the second operating body 97 are all magnetic components, and the flatness of the inner and outer surfaces of the first air housing 60 and the inner and outer surfaces of the second air housing 70 are adjusted by magnetic attraction. Specifically, the base 93, the first operating body 95 and the second operating body 97 are all electromagnets, and during the operation of the fresh air device, the base 93, the first operating body 95 and the second operating body 97 are all powered.

[0082] Please also read Figure 6 , Figure 7 , Figure 8 and Fig. 9 , the first operating body 95 and the second operating body 97 both have an initial position, an adsorption position and a separation position relative to the base 93. Taking the adjustment member 90 located at the first wind housing 60 as an example, when the first operating body 95 is located at the initial position relative to the base 93, the base 93 and the first operating body 95 are arranged side by side along the radial direction of the base 93 and abut against each other, and the distance between the two farthest points between the first operating body 95 and the base 93 is equal to the sum of the diameters of the first operating body 95 and the base 93. At this time, a small reverse current is passed between the base 93 and the first operating body 95, and there is an attraction force between the base 93 and the operating body, and the attraction force is small, and the wind pressure value of the inner surface of the wind housing corresponding to the adjustment member 90 is equal to the set threshold.

[0083] When the first operating body 95 is located at a separated position relative to the base 93, the base 93 and the first operating body 95 are spaced apart along the radial direction of the base 93, and the distance between the two points farthest apart between the first operating body 95 and the base 93 is greater than the sum of the diameters of the first operating body 95 and the base 93. At this time, a relatively large current in the same direction flows between the base 93 and the first operating body 95, and there is a repulsive force between the base 93 and the operating body, and the wind pressure value of the inner surface of the wind housing corresponding to the adjustment member 90 is less than the set threshold.

[0084] When the first operating body 95 is located at the adsorption position relative to the base 93, the base 93 and the first operating body 95 are arranged along the radial direction of the base 93 and partially overlap, and the distance between the two points farthest apart between the first operating body 95 and the base 93 is less than the sum of the diameters of the first operating body 95 and the base 93. At this time, a large reverse current is passed between the base 93 and the first operating body 95, and there is an adsorption force between the base 93 and the operating body, and the wind pressure value of the inner surface of the wind shell corresponding to the adjustment member 90 is greater than the set threshold. The second operating body 97 is used to adjust the flatness of the outer surface of the first wind shell 60, and its operation method is the same as the adjustment method of the first operating body 95, so it will not be repeated here. In addition, when all adjustment areas are located on the second wind shell 70, the adjustment method of the adjustment assembly is the same as above, so it will not be repeated here. By setting the base 93 and the operating body to be electromagnets, the adjustment efficiency of each adjustment body is higher, so that the air supply efficiency of the air duct structure 1 can be quickly improved.

[0085] In the air inlet and outlet ducts, when a plurality of adjustment areas are provided on the first air shell 60, the threshold value is defined as the average value of the wind pressure values ​​collected by the collection components in all the adjustment areas on the first air shell 60. When a plurality of adjustment areas are provided on the second air shell 70, the threshold value is defined as the average value of the wind pressure values ​​collected by the collection components in all the adjustment areas on the second air shell 70. Therefore, the wind loss on the entire first air shell 60 and the second air shell 70 is relatively small, so that the air duct structure 1 has a better air supply efficiency. In this embodiment, the flow fields formed in the air inlet and outlet ducts are relatively uniform, which helps to reduce the noise generated during the operation of the air duct structure 1.

[0086] It is worth mentioning that, specifically, the calculation of the average value is performed by the controller. When there are adjustment areas inside the first wind shell 60, outside the first wind shell 60, inside the second wind shell 70, and outside the second wind shell 70, the calculation processes of the average values ​​inside the first wind shell 60, outside the first wind shell 60, inside the second wind shell 70, and outside the second wind shell 70 are independent of each other and do not affect each other. That is to say, when calculating the average wind pressure inside the first wind shell 60, the controller only sums up the wind pressure values ​​of all adjustment areas inside the first wind shell 60 and calculates the average value, and only compares the wind pressure value of each adjustment area located inside the first wind shell 60 with the average wind pressure value inside the first wind shell 60. When calculating the average wind pressure outside the first wind shell 60, the controller only sums up the wind pressure values ​​of all adjustment areas outside the first wind shell 60 and calculates the average value, and only compares the wind pressure value of each adjustment area located outside the first wind shell 60 with the average wind pressure value outside the first wind shell 60. The process of obtaining the average value of the adjustment area on the second wind shell 70 is similar to the above, so it will not be repeated here. In this embodiment, the set threshold corresponding to each adjustment area in the first wind shell 60 is equal, the set threshold corresponding to each adjustment area outside the first wind shell 60 is equal, the set threshold corresponding to each adjustment area in the second wind shell 70 is equal, and the set threshold corresponding to each adjustment area outside the second wind shell 70 is equal. Any two of the set threshold corresponding to each adjustment area in the first wind shell 60, the set threshold corresponding to each adjustment area outside the first wind shell 60, the set threshold corresponding to each adjustment area in the second wind shell 70, and the set threshold corresponding to each adjustment area outside the second wind shell 70 may be equal or unequal.

[0087] Taking the adjustment area being located inside the first wind shell 60 as an example, when the wind pressure value of any adjustment area in the first wind shell 60 is greater than the average wind pressure value in the first wind shell 60, the adjustment member 90 corresponding to the adjustment area contracts and makes the inner surface of the first wind shell 60 defining the adjustment area concave, so as to flatten the protrusion where the adjustment area is located. When the wind pressure value of any adjustment area in the first wind shell 60 is less than the average wind pressure value in the first wind shell 60, the adjustment member 90 corresponding to the adjustment area extends and makes the inner surface of the first wind shell 60 defining the adjustment area protrude, so as to fill the pit where the adjustment area is located. When the wind pressure value of each adjustment area is equal to the average wind pressure value in the first wind shell 60, the inner surface of the entire first wind shell 60 transitions smoothly. In addition, the adjustment method when the adjustment area is located on the outer surface of the first wind shell 60, the adjustment area is located on the inner surface of the second wind shell 70, and the adjustment area is located on the outer surface of the second wind shell 70 is the same as described above, so it is not repeated here.

[0088] Next, the working process of the fresh air device is described in detail.

[0089] When the fresh air device takes in air, under the action of the first fan 10, the outdoor air flow sequentially flows into the room through the first air inlet 814, the inside of the first air duct, the first heat exchanger 30, the outer surface of the second air housing 70 and the first air outlet 816. At the same time, under the action of the second fan 20, the indoor air flow sequentially flows into the outside through the second air inlet 818, the second air duct, the second heat exchanger 40, the outer surface of the first air housing 60 and the second air outlet 819.

[0090] During this process, all collecting parts corresponding to the adjustment area inside the first wind shell 60, all collecting parts corresponding to the adjustment area outside the first wind shell 60, all collecting parts corresponding to the adjustment area inside the second wind shell 70, and all collecting parts corresponding to the adjustment area outside the second wind shell 70 collect the wind pressure values ​​of the corresponding adjustment areas and send them to the controller.

[0091] The controller calculates the average wind pressure value inside the first wind shell 60 based on all wind pressure values ​​corresponding to all adjustment areas inside the first wind shell 60, and calculates the average wind pressure value outside the first wind shell 60 based on all wind pressure values ​​corresponding to all adjustment areas outside the first wind shell 60. The controller also calculates the average wind pressure value inside the second wind shell 70 based on all wind pressure values ​​corresponding to all adjustment areas inside the second wind shell 70, and calculates the average wind pressure value outside the second wind shell 70 based on all wind pressure values ​​corresponding to all adjustment areas outside the second wind shell 70.

[0092] When the wind pressure value of any adjustment area in the first wind shell 60 is not equal to the average wind pressure value in the first wind shell 60, the adjustment member 90 corresponding to the adjustment area adjusts the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the average wind pressure value in the first wind shell 60.

[0093] When the wind pressure value of any adjustment area outside the first wind shell 60 is not equal to the average wind pressure outside the first wind shell 60, the adjustment part 90 corresponding to the adjustment area adjusts the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the average wind pressure outside the first wind shell 60.

[0094] When the wind pressure value of any adjustment area in the second wind shell 70 is not equal to the average wind pressure value in the second wind shell 70, the adjustment member 90 corresponding to the adjustment area adjusts the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the average wind pressure value in the second wind shell 70.

[0095] When the wind pressure value of any adjustment area outside the second wind shell 70 is not equal to the average wind pressure outside the second wind shell 70, the adjustment part 90 corresponding to the adjustment area adjusts the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the average wind pressure outside the second wind shell 70.

[0096] In the above-mentioned fresh air device and its air duct structure 1, when the air duct structure 1 is working, each adjustment component is used to collect the wind pressure value of the current adjustment area, and when the wind pressure value of the adjustment area is not equal to the set threshold value corresponding thereto, adjust the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the set threshold value corresponding thereto. Therefore, under the action of the collection component and the adjustment component 90, the wind loss of the airflow is reduced during the flow process, thereby effectively improving the air supply efficiency of the air duct structure 1.

[0097] See also Fig.10 The present application also provides a method for controlling an air duct structure, which is implemented using the air duct structure in any of the above embodiments. The method for controlling an air duct structure comprises the following steps:

[0098] Step S100: During the operation of the air duct structure, the adjustment component collects the wind pressure value of the current adjustment area;

[0099] Step S200: When the wind pressure value of the current adjustment area is not equal to the corresponding set threshold, the adjustment component adjusts the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the corresponding set threshold.

[0100] Each adjustment component is used to collect the wind pressure value of the current adjustment area, and adjust the wind pressure of the adjustment area when the wind pressure value of the adjustment area is not equal to the corresponding set threshold value, until the wind pressure value of the adjustment area is equal to the corresponding set threshold value. Therefore, under the action of the collection component and the adjustment component, the wind loss of the airflow is reduced during the flow process, thereby effectively improving the air supply efficiency of the air duct structure.

[0101] Specifically, the specific operation process of step S100 and step S200 is similar to the above-mentioned embodiment corresponding to the air duct structure part, so it is not repeated here.

[0102] See also Fig.11 Each adjustment component includes a collection component and an adjustment component. Step S100: During the operation of the air duct structure, the adjustment component collects the wind pressure value of the current adjustment area, including: Step S110: During the operation of the air duct structure, the collection component collects the wind pressure value of the current adjustment area;

[0103] Step S200: When the wind pressure value of the adjustment area currently located is not equal to the set threshold value corresponding thereto, the adjustment component adjusts the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the set threshold value corresponding thereto, including: Step S210: When the wind pressure value of the adjustment area currently located is not equal to the set threshold value corresponding thereto, the adjustment component adjusts the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the set threshold value corresponding thereto. Specifically, the specific operation process of step S110 and step S210 is similar to the embodiment corresponding to the above-mentioned air duct structure part, so it will not be repeated here.

[0104] See also Fig.12 In one embodiment, the outdoor airflow entering the air inlet flow channel flows through the interior of the first air housing, the first heat exchanger, and the outer surface of the second air housing in sequence. In the air inlet flow channel, when the adjustment area is set on the first air housing, step S210: when the wind pressure value of the adjustment area currently located is not equal to the set threshold value corresponding thereto, the adjustment member adjusts the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the set threshold value corresponding thereto, including:

[0105] Step S211: the adjusting member in the adjustment area adjusts the flatness of the inner surface of the first wind shell according to the wind pressure value of the collecting member.

[0106] In the air inlet flow channel, when the adjustment area is set on the second air shell, step S210: when the wind pressure value of the adjustment area currently located is not equal to the set threshold value corresponding thereto, the adjustment member adjusts the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the set threshold value corresponding thereto, including:

[0107] Step S212: the adjusting member in the adjusting area adjusts the flatness of the outer surface of the second wind shell according to the wind pressure value of the collecting member.

[0108] That is to say, when all the adjustment areas are located inside the first wind shell, each collecting component is used to collect the wind pressure value of the corresponding adjustment area, and when the wind pressure value of any adjustment area is not equal to the set threshold value corresponding to the adjustment area, the adjustment component corresponding to the adjustment area adjusts the flatness of the inner surface of the first wind shell that defines the adjustment area, so that the wind pressure value in the adjustment area is equal to the set threshold value. When the adjustment area is set on the second wind shell, the adjustment component in the adjustment area adjusts the flatness of the outer surface of the second wind shell according to the wind pressure value of the collecting component. That is to say, when all the adjustment areas are located outside the second wind shell, each collecting component is used to collect the wind pressure value of the corresponding adjustment area, and when the wind pressure value of any adjustment area is not equal to the set threshold value corresponding to the adjustment area, the adjustment component corresponding to the adjustment area adjusts the flatness of the inner surface of the second wind shell that defines the adjustment area, so that the wind pressure value in the adjustment area is equal to the set threshold value.

[0109] In one embodiment, in the air inlet flow channel, the main reason for the abnormal wind pressure value in any adjustment area is that the surface defining the adjustment area is uneven. If the wind pressure value of a single adjustment area is greater than a set threshold, it means that the adjustment area is a raised area. If the wind pressure value of a single adjustment area is less than the set threshold, it means that the adjustment area is a pit area. At this time, if the wind pressure value in the adjustment area is less than the set threshold corresponding to the adjustment area, the pit is filled so that the depression of the pit is reduced. If the wind pressure value in the adjustment area is less than the set threshold corresponding to the adjustment area, the bulge is weakened so that the protrusion of the bulge is reduced. Furthermore, the inner surface of the first wind shell or the outer surface of the second wind shell that defines the adjustment area can become flat, so that the wind loss during the air intake process is smaller.

[0110] Preferably, there are multiple adjustment areas, some of which are located on the inner surface of the first wind shell, and the remaining parts are located on the outer surface of the second wind shell. Therefore, during the operation of the fresh air device, the wind pressure of the parts of the air inlet flow channel defined by the first wind shell and the second wind shell can be adjusted, thereby reducing the formation of turbulence when the outdoor air flows into the room.

[0111] Specifically, the specific operation process of step S211 and step S212 is similar to the above-mentioned embodiment corresponding to the air duct structure part, so it will not be repeated here.

[0112] In the air inlet duct, when a plurality of adjustment areas are provided on the first wind shell, the threshold value is set to be defined as the average value of the wind pressure values ​​collected by the collection member in all the adjustment areas on the first wind shell. When a plurality of adjustment areas are provided on the second wind shell, the threshold value is set to be defined as the average value of the wind pressure values ​​collected by the collection member in all the adjustment areas on the second wind shell. Therefore, in the air inlet duct, the wind losses on the first wind shell and the second wind shell are relatively small, so that the air duct structure has a better air supply efficiency. In this embodiment, the smoothness formed in the air inlet duct is relatively uniform, which helps to reduce the noise generated during the operation of the air duct structure.

[0113] It is worth mentioning that, specifically, the calculation of the average value is performed by the controller. When there are adjustment areas inside and outside the first wind shell, the calculation processes of the average values ​​inside and outside the first wind shell are independent of each other and do not affect each other. That is to say, when calculating the average wind pressure value inside the first wind shell, the controller only sums up the wind pressure values ​​of all adjustment areas inside the first wind shell and calculates the average value, and only compares the wind pressure value of each adjustment area located inside the first wind shell with the average wind pressure value inside the first wind shell. When calculating the average wind pressure value outside the second wind shell, the controller only sums up the wind pressure values ​​of all adjustment areas outside the second wind shell and calculates the average value, and only compares the wind pressure value of each adjustment area located outside the second wind shell with the average wind pressure value outside the second wind shell. In this embodiment, the set threshold corresponding to each adjustment area inside the first wind shell is equal, and the set threshold corresponding to each adjustment area outside the first wind shell is also equal. The set threshold corresponding to each adjustment area inside the first wind shell may be equal to or different from the set threshold corresponding to each adjustment area outside the first wind shell.

[0114] Taking the adjustment area being located in the first wind shell as an example, when the wind pressure value of any adjustment area in the first wind shell is greater than the average wind pressure value in the first wind shell, the adjustment member corresponding to the adjustment area adjusts the wind pressure in the adjustment area until the wind pressure value in the adjustment area is equal to the average wind pressure value in the first wind shell. When the wind pressure value of any adjustment area in the first wind shell is less than the average wind pressure value in the first wind shell, the adjustment member corresponding to the adjustment area adjusts the wind pressure in the adjustment area until the wind pressure value in the adjustment area is equal to the average wind pressure value in the first wind shell.

[0115] See also Fig.13 In one embodiment, the indoor airflow entering the air outlet flow channel flows through the interior of the second air housing, the second heat exchanger, and the outer surface of the first air housing in sequence. In the air outlet flow channel, when the adjustment area is set on the second air housing, step 210: when the wind pressure value of the adjustment area currently located is not equal to the set threshold value corresponding thereto, the adjustment member adjusts the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the set threshold value corresponding thereto, including:

[0116] Step 213: the adjusting member in the adjusting area adjusts the flatness of the inner surface of the second wind shell according to the wind pressure value of the collecting member;

[0117] In the air outlet flow channel, when the adjustment area is set on the first air shell, step 210: when the wind pressure value of the adjustment area currently located is not equal to the set threshold value corresponding thereto, the adjustment member adjusts the wind pressure of the adjustment area until the wind pressure value of the adjustment area is equal to the set threshold value corresponding thereto, including:

[0118] Step 214: the adjustment member in the adjustment area adjusts the flatness of the outer surface of the first wind shell according to the wind pressure value of the collecting member.

[0119] That is to say, when all the adjustment areas are located inside the second wind shell, each collecting component is used to collect the wind pressure value of the corresponding adjustment area, and when the wind pressure value of any adjustment area is not equal to the set threshold value corresponding to the adjustment area, the adjustment component corresponding to the adjustment area adjusts the flatness of the inner surface of the second wind shell that defines the adjustment area, so that the wind pressure value in the adjustment area is equal to the set threshold value. When the adjustment area is set on the first wind shell, the adjustment component in the adjustment area adjusts the flatness of the outer surface of the first wind shell according to the wind pressure value of the collecting component. That is to say, when all the adjustment areas are located outside the first wind shell, each collecting component is used to collect the wind pressure value of the corresponding adjustment area, and when the wind pressure value of any adjustment area is not equal to the set threshold value corresponding to the adjustment area, the adjustment component corresponding to the adjustment area adjusts the flatness of the outer surface of the first wind shell that defines the adjustment area, so that the wind pressure value in the adjustment area is equal to the set threshold value.

[0120] Preferably, there are multiple adjustment areas, some of which are located on the inner surface of the second wind shell, and the remaining parts are located on the outer surface of the first wind shell. Therefore, during the operation of the fresh air device, the wind pressure of the parts of the air outlet flow channel defined by the first wind shell and the second wind shell can be adjusted, thereby reducing the formation of turbulence in the process of outdoor airflow flowing into the room. Specifically, the specific operation process of step S213 and step S214 is similar to the embodiment corresponding to the above-mentioned air duct structure part, so it is not repeated here.

[0121] In the air outlet duct, when several adjustment areas are provided on the first wind shell, the set threshold is defined as the average value of the wind pressure values ​​collected by the collecting components in all the adjustment areas on the first wind shell; when several adjustment areas are provided on the second wind shell, the set threshold is defined as the average value of the wind pressure values ​​collected by the collecting components in all the adjustment areas on the second wind shell.

[0122] Therefore, in the air outlet flow channel, the wind loss on the first air shell and the second air shell is small, so that the air duct structure has a better air supply efficiency. In this embodiment, the flow field formed in the air outlet flow channel is relatively uniform, which helps to reduce the noise generated during the operation of the air duct structure.

[0123] It is worth mentioning that, specifically, the calculation of the average value is performed by the controller. Taking the adjustment area located in the second wind shell as an example, when the wind pressure value of any adjustment area in the second wind shell is greater than the average wind pressure value in the second wind shell, the adjustment member corresponding to the adjustment area adjusts the wind pressure in the adjustment area until the wind pressure value in the adjustment area is equal to the average wind pressure value in the second wind shell. When the wind pressure value of any adjustment area in the second wind shell is less than the average wind pressure value in the second wind shell, the adjustment member corresponding to the adjustment area adjusts the wind pressure in the adjustment area until the wind pressure value in the adjustment area is equal to the average wind pressure value in the second wind shell.

[0124] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
