[0050] Reference below Figures 1-12 A fresh air module according to an embodiment of the present invention is described.

[0051] Combine Figure 1 、 Figure 5 、 Figure 6 and Figure 12 According to the present invention, the fresh air module 100 includes a shell 110 and a rotating assembly 120, wherein the shell 110 has a fresh air inlet 111, an indoor air inlet 112, an indoor air outlet 113 and an outdoor air outlet 114, and the rotating assembly 120 is arranged in the shell 110 and includes a first wind shield 121. The first wind shield 121 divides the inner cavity of the shell 110 into a connected air inlet cavity 115 and a wind wheel cavity 116. The fresh air inlet 111 and the indoor air inlet 112 are respectively connected to the air inlet cavity 115, and the indoor air outlet 113 and the outdoor air outlet 114 are respectively connected to the wind wheel cavity 116. The first wind shield 121 can rotate in the shell 110 to open and close the fresh air inlet 111 and the indoor air inlet 112.

[0052] Specifically, a cavity is formed in the outer shell 110, that is, the inner cavity of the outer shell 110, the rotating assembly 120 is installed in the inner cavity of the outer shell 110, and the rotating assembly 120 includes a first wind shield 121 and a second wind shield 122. The first wind shield 121 can separate the inner cavity of the outer shell 110 into an air inlet cavity 115 and a wind wheel cavity 116.

[0053] Furthermore, a fresh air inlet 111, an indoor air inlet 112, an indoor air outlet 113 and an outdoor air outlet 114 are formed on the outer shell 110. The fresh air inlet 111 and the indoor air inlet 112 can be connected to the air inlet cavity 115, and the air inlet cavity 115 can be connected to the external space through the fresh air inlet 111 and the indoor air inlet 112.

[0054] The outdoor air outlet 114 and the indoor air outlet 113 may be communicated with the wind wheel cavity 116 , and the wind wheel cavity 116 may be communicated with the external space through the outdoor air outlet 114 and the indoor air outlet 113 .

[0055] It should be noted that "external space" refers to the external space of the fresh air module 100, which may include indoor space and outdoor space. Specifically, in the actual usage scenario of the fresh air module 100, the fresh air inlet 111 and the outdoor air outlet 114 are both connected to the outdoor space, and the indoor air inlet 112 and the indoor air outlet 113 are both connected to the outdoor space.

[0056] Furthermore, the first wind shield 121 is rotatable in the outer shell 110, and the first wind shield 121 is used to open and close the fresh air inlet 111 and the indoor air inlet 112. When the first wind shield 121 is rotated to the position of the fresh air inlet 111, the first wind shield 121 can close the fresh air inlet 111 and open the indoor air inlet 112; when the first wind shield 121 is rotated to the position of the indoor air inlet 112, the first wind shield 121 can close the indoor air inlet 112 and open the fresh air inlet 111.

[0057] The rotating assembly 120 further includes a second wind shield 122 , which is rotatable in the housing 110 to open and close the indoor air outlet 113 and the outdoor air outlet 114 .

[0058] Specifically, the second wind shield 122 is rotatably disposed in the wind wheel cavity 116 so that the second wind shield 122 opens and closes the indoor air outlet 113 and the outdoor air outlet 114. When the second wind shield 122 rotates to the outdoor air outlet 114, the outdoor air outlet 114 is closed and the indoor air outlet 113 is opened at the same time; when the second wind shield 122 rotates to the indoor air outlet 113, the indoor air outlet 113 is closed and the outdoor air outlet 114 is opened at the same time.

[0059] Therefore, by arranging a rotatable rotating component 120 in the outer shell 110, the rotating component 120 can selectively open and close the fresh air inlet 111, the indoor air inlet 112, the outdoor air outlet 114 and the indoor air outlet 113, which is beneficial to increase the air supply modes that the fresh air module 100 can achieve and improve the functionality of the fresh air module 100, that is, multiple air flow channels can be formed between the fresh air inlet 111, the indoor air inlet 112, the outdoor air outlet 114 and the indoor air outlet 113. Under different air supply modes, the air flow passes through different air flow channels. By adjusting the opening and closing states of different air inlets and outlets, the opening and closing states of multiple air flow channels can be adjusted, thereby realizing different air supply modes of the fresh air module 100.

[0060] The fresh air module 100 also includes a wind wheel 130, which is rotatably arranged in the wind wheel cavity 116. When the wind wheel 130 rotates in the wind wheel cavity 116, it can drive the air in the external space to form an airflow. The airflow can enter the air inlet cavity 115 through the fresh air inlet 111 or the indoor air inlet 112, and then the airflow flows from the air inlet cavity 115 into the wind wheel cavity 116, and flows into the external space through the outdoor air outlet 114 or the indoor air outlet 113.

[0061] In addition, combined Figures 1 to 4 The fresh air module 100 further includes a filter assembly 140 , which includes a filter element 141 . The filter element 141 is disposed in the air inlet cavity 115 and is connected to the first wind shield 121 so as to rotate together with the first wind shield 121 .

[0062] Specifically, the filter element 141 is installed in the air inlet chamber 115. When the air flow flows into the air inlet chamber 115 and flows from the air inlet chamber 115 into the wind wheel chamber 116, the air flow flows through the filter element 141. The filter element 141 can filter the air, which is beneficial to improve the quality of the air flowing out of the fresh air module 100, realize the purification function of the fresh air module 100 on the air flow, and further improve the functionality of the fresh air module 100.

[0063] Furthermore, the filter element 141 is connected to the first wind shield 121. For example, a connecting structure can be provided on the first wind shield 121 so that the filter element 141 can be connected to the first wind shield 121, and the filter element 141 can be pre-installed on the first wind shield 121 outside the outer shell 110, which is convenient for positioning and installation of the filter element 141, and there is no need to provide an additional structure for installing the filter element 141 in the outer shell 110, which is conducive to simplifying the structure of the fresh air module 100, making the structure of the fresh air module 100 simple, and the filter element 141 can rotate synchronously with the first wind shield 121, which is conducive to preventing the filter element 141 from interfering with the rotation of the first wind shield 121, ensuring the rotation effect of the first wind shield 121, and thus ensuring the opening and closing effect of the first wind shield 121 on the fresh air inlet 111 and the indoor air inlet 112.

[0064] According to the fresh air module 100 of the present invention, by setting the rotating component 120, the opening and closing states of different air inlets and outlets can be flexibly adjusted, which is conducive to increasing the air supply modes that the fresh air module 100 can achieve, improving the functionality of the fresh air module 100, and there is no need to set structures such as air valves, which is conducive to simplifying the component settings of the fresh air module 100, reducing the production cost of the fresh air module 100, and realizing the miniaturization design of the fresh air module 100. In addition, by setting the filter component 140, the purification function of the fresh air module 100 on the air flow can be realized, further improving the fresh air module The functionality of block 100 facilitates the positioning and installation of the filter 141 by connecting the filter 141 to the first wind shield 121, and there is no need to set an additional structure for installing the filter 141 in the shell 110, so as to further simplify the structure of the fresh air module 100. At the same time, the filter 141 can rotate synchronously with the first wind shield 121 to prevent the filter 141 from interfering with the rotation of the first wind shield 121, thereby ensuring the rotation effect of the first wind shield 121, which is beneficial to ensure the opening and closing effect of the first wind shield 121 on the fresh air inlet 111 and the indoor air inlet 112.

[0065] Combine Figure 1 、 Figure 4 and Figure 6 In some embodiments of the present invention, one of the first wind shield 121 and the filter 141 is provided with a plug-in portion 1411, and the other is provided with a plug-in fitting portion 1211, and the plug-in portion 1411 is plug-fitted with the plug-in fitting portion 1211 to connect the filter 141 to the first wind shield 121.

[0066] Specifically, the outer shell 110 has an installation port 117 connected to the air inlet chamber 115, and the plug-in portion 1411 or the plug-in fitting portion 1211 is arranged on the first wind shield 121 and is arranged opposite to the installation port 117, so that the plug-in portion 1411 can be smoothly plugged and fitted with the plug-in fitting portion 1211, so that the filter element 141 can be connected to the first wind shield 121.

[0067] Among them, a plug-in board is provided on the first wind shield 121, the plug-in fitting part 1211 is a plug-in interface and the plug-in interface is formed on the plug-in board, the plug-in interface is arranged relatively close to the wind wheel 130, and the plug-in part 1411 is constructed as a rib, which can be plug-fitted with the plug-in interface, thereby connecting the filter element 141 to the first wind shield 121, so that the filter element 141 can rotate synchronously with the first wind shield 121.

[0068] Furthermore, since the filter element 141 can rotate synchronously with the first wind shield 121 and the plug interface is arranged relatively close to the wind wheel 130, when the filter element 141 is connected to the first wind shield 121 through the plug-in portion 1411 and the plug-in fitting portion 1211, the filter element 141 can fit together with the side wall of the first wind shield 121 close to the wind wheel 130, thereby eliminating the axial movement gap between the filter element 141 and the first wind shield 121, preventing air leakage caused by the axial gap between the filter element 141 and the first wind shield 121, which is beneficial to increasing the air volume of the fresh air module 100.

[0069] In addition, the plug-in fitting portion 1211 can be detached from the plug-in portion 1411 , thereby achieving a detachable connection between the filter element 141 and the first wind shielding element 121 , which facilitates the disassembly or replacement of the filter element 141 .

[0070] Of course, it is understandable that the plug-in portion 1411 and the plug-in fitting portion 1211 can also be constructed as other structures. The specific structure can be determined in actual production and processing, and is not specifically limited here, as long as the connection effect of the filter element 141 and the first wind shield element 121 is guaranteed.

[0071] Combine Figures 1 to 3 In some embodiments of the present invention, the housing 110 has a mounting opening 117 communicating with the air inlet cavity 115 , and the filter element 141 is adapted to be mounted to the air inlet cavity 115 through the mounting opening 117 .

[0072] Specifically, an installation opening 117 is provided at a position adjacent to the outer shell 110 and the air inlet chamber 115. The installation opening 117 is formed on the wall of the air inlet chamber 115. The filter element 141 can be installed in the air inlet chamber 115 through the installation opening 117. The air in the external space flows into the air inlet chamber 115 and flows through the filter element 141 in the process of flowing from the air inlet chamber 115 into the wind wheel chamber 116. The filter element 141 filters the air to improve the quality of the air flowing out of the fresh air module 100.

[0073] The filter assembly 140 further includes a push-pull member 142 , and the filter element 141 can be pushed and pulled on the housing 110 under the drive of the push-pull member 142 .

[0074] Specifically, the push-pull member 142 can be connected to the filter element 141, and the filter element 141 can be pushed into the air inlet chamber 115 through the push-pull member 142, which is conducive to improving the installation efficiency of the filter element 141, thereby improving the production and installation efficiency of the fresh air module 100. In addition, the filter element 141 can also be pulled out of the air inlet chamber 115 through the push-pull member 142 to facilitate the maintenance or replacement of the filter element 141.

[0075] Combine Figures 4 to 7In some embodiments of the invention, the push-pull member 142 is provided with a first connecting portion 1421 and a second connecting portion 1422, the filter element 141 is provided with a first connecting fitting portion 1412, and the outer shell 110 is provided with a second connecting fitting portion 118, wherein, when the filter assembly 140 is in the initial state where the outer shell 110 is installed in place, the push-pull member 142 closes the installation port 117, the first connecting portion 1421 is connected to the first connecting fitting portion 1412, and the second connecting portion 1422 is connected to the second connecting fitting portion 118.

[0076] Specifically, the push-pull member 142 is provided with a first connecting portion 1421, and the filter member 141 is provided with a first connecting matching portion 1412. The first connecting portion 1421 can be matched with the first connecting matching portion 1412 to connect the filter member 141 to the push-pull member 142; further combined Figure 1 and Figure 11 A second connecting portion 1422 is also provided on the push-pull member 142, and a second connecting matching portion 118 is provided on the shell 110. The second connecting portion 1422 can be matched with the second connecting matching portion 118 to connect with the push-pull member 142, so that the push-pull member 142 can be connected to the shell 110.

[0077] Further, combined with Figures 1 to 3 When the filter assembly 140 is in the initial state of being installed in place in the outer shell 110, the filter element 141 is completely installed in the air inlet chamber 115 and is connected to the first wind shield 121, but at this time the first wind shield 121 does not drive the filter element 141 to rotate. At this time, the push-pull member 142 is arranged opposite to the installation port 117, and the push-pull member 142 can close the installation port 117 to prevent air leakage at the installation port 117, which is beneficial to improving the air outlet effect of the fresh air module 100.

[0078] Further integration Figure 6 At this time, the first connecting portion 1421 is connected to the first connecting matching portion 1412, so that the filter element 141 and the push-pull member 142 are in a connected state, and at the same time, the second connecting portion 1422 is connected to the second connecting matching portion 118, so that the push-pull member 142 is connected to the shell 110, so as to fix the push-pull member 142 at the position of the installation port 117, ensure the sealing effect of the push-pull member 142 on the installation port 117, and prevent the push-pull member 142 from detaching from the shell 110, thereby preventing the filter element 141 from escaping from the air inlet chamber 115, which is beneficial to improve the assembly reliability of the filter component 140 in the initial state when it is installed in place in the shell 110.

[0079] Combine Figure 8 and Figure 9 In some embodiments of the present invention, the first connecting portion 1421 and the first connecting fitting portion 1412 can be movably connected, or the first connecting portion 1421 and the first connecting fitting portion 1412 can be detachably connected.

[0080] Specifically, the first connecting portion 1421 and the first connecting fitting portion 1412 are movably connected, so that the push-pull member 142 and the filter element 141 are movably connected. When the first wind shield 121 drives the filter element 141 to rotate, the first connecting portion 1421 and the first connecting fitting portion 1412 can move relative to each other, so that the filter element 141 and the push-pull member 142 can move relative to each other, to ensure that the first wind shield 121 can drive the filter element 141 to move relative to the push-pull member 142, to avoid the push-pull member 142 interfering with the rotation of the filter element 141 and the first wind shield 121, and at the same time to prevent the filter element 141 from driving the push-pull member 142 to move, to ensure the sealing effect of the push-pull member 142 on the installation port 117.

[0081] Alternatively, the first connecting portion 1421 is detachably connected to the first connecting fitting portion 1412, so that the push-pull member 142 is detachably connected to the filter element 141. When the first wind shield 121 drives the filter element 141 to rotate, the first connecting portion 1421 can be separated from the first connecting fitting portion 1412, so that the filter element 141 can be separated from the push-pull member 142, to ensure that the first wind shield 121 can drive the filter element 141 to move relative to the push-pull member 142, to avoid the push-pull member 142 interfering with the rotation of the filter element 141 and the first wind shield 121, and at the same time, it can prevent the filter element 141 from driving the push-pull member 142 to move, to ensure the sealing effect of the push-pull member 142 on the installation port 117. In addition, by making the first connecting portion 1421 detachably connected to the first connecting fitting portion 1412, it is convenient to replace the filter element 141 separately, thereby reducing the maintenance and replacement costs of the filter assembly 140.

[0082] It should be noted that when it is necessary to pull the filter element 141 out of the air inlet chamber 115 or install the filter element 141 into the air inlet chamber 115, the first connecting portion 1421 is connected to the first connecting mating portion 1412, thereby ensuring that the filter element 141 can be pushed and pulled by the push-pull member 142 to pull the filter element 141 out of the air inlet chamber 115 or push the filter element 141 into the air inlet chamber 115.

[0083] Combine Figure 2 and Figure 3 as well as Figure 9 and Figure 10 In some embodiments of the present invention, the push-pull member 142 includes a push-pull body 1423 , which is used to open and close the installation opening 117 .

[0084] Specifically, the push-pull body 1423 can be plugged into the mounting port 117, and the shape of the push-pull body 1423 is adapted to the shape of the mounting port 117. When the push-pull body 1423 is plugged into the mounting port 117, the push-pull body 1423 can close the mounting port 117. When the push-pull body 1423 cancels the cooperation with the mounting port 117, the mounting port 117 opens.

[0085] In some examples, the push-pull member 142 further includes a pressing portion 1424 . The pressing portion 1424 is movably disposed on the push-pull body 1423 between a first position and a second position. The second connecting portion 1422 is disposed on the pressing portion 1424 .

[0086] Specifically, combined Figure 2 and Figure 3 as well as Figure 11 A pressing portion 1424 is provided on the push-pull body 1423, and the pressing portion 1424 can move relative to the push-pull body 1423 so that the pressing portion 1424 can move between the first position and the second position. A second connecting portion 1422 is provided on the pressing portion 1424, and the pressing portion 1424 can drive the second connecting portion 1422 to move synchronously, so that the pressing portion 1424 can be connected to or disconnected from the second connecting mating portion 118 by moving the pressing portion 1424 between the first position and the second position.

[0087] Among them, combined Figure 6 and Figure 7 When the pressing portion 1424 is in the first position, the second connecting portion 1422 is connected to the second connecting matching portion 118 so that the push-pull member 142 is fixed at the position of the closed installation opening 117. Figure 4 and Figure 5 When the pressing portion 1424 is in the second position, the second connecting portion 1422 is disconnected from the second connecting mating portion 118 so that the push-pull member 142 can be removed from the housing 110 .

[0088] Specifically, when the pressing portion 1424 is in the first position, the second connecting portion 1422 is connected to the second connecting mating portion 118 so that the pressing portion 1424 can be connected to the shell 110, that is, the push-pull member 142 can be connected to the shell 110, and the push-pull member 142 can be fixed at the position of the mounting port 117 to ensure the sealing effect of the push-pull member 142 on the mounting port 117 and prevent the push-pull member 142 from detaching from the mounting port 117.

[0089] When the pressing portion 1424 is in the second position, the second connecting portion 1422 is disconnected from the second connecting mating portion 118, so that the pressing portion 1424 is disconnected from the outer shell 110, that is, the push-pull member 142 can be disconnected from the outer shell 110. At this time, the push-pull member 142 can be removed from the outer shell 110. For example, when the filter element 141 needs to be removed from the air inlet chamber 115, the filter element 141 should be pulled out of the air inlet chamber 115 through the push-pull member 142. At this time, the push-pull member 142 needs to be pulled out from the installation port 117 first. Therefore, the pressing portion 1424 needs to be in the second position at this time to ensure that the push-pull member 142 can be removed from the outer shell 110.

[0090] In addition, combined Figures 8 to 10 The first connecting part 1421 is provided on the push-pull body 1423, and the filter element 141 can be connected to the push-pull body 1423 through the first connecting part 1421 and the first connecting matching part 1412, so that the filter element 141 is driven by the push-pull body 1423 to prevent the pressing part 1424 from affecting the connection state between the second connecting part 1422 and the second connecting matching part 118 when moving between the first position and the second position, thereby ensuring the connection stability between the filter element 141 and the push-pull body 1423, and ensuring the push-pull effect of the push-pull member 142 on the filter element 141.

[0091] It should be noted that the first position is arranged farther away from the air inlet chamber 115 than the second position, and the second position is arranged closer to the air inlet chamber 115 than the first position. "The pressing portion 1424 is in the second position" means that the pressing portion 1424 moves to the extreme position relative to the push-pull body 1423 toward the side close to the air inlet chamber 115, which can also be understood as the pressing portion 1424 is in a pressing state. "The pressing portion 1424 is in the second position" means that the pressing portion 1424 moves to the extreme position relative to the push-pull body 1423 away from the air inlet chamber 115, which can also be understood as the pressing portion 1424 is in a restored state.

[0092] Combine Figure 1 as well as Figures 5 to 7 In some embodiments of the present invention, a reset member 150 is provided between the push-pull body 1423 and the pressing portion 1424 , and the reset member 150 is used to drive the pressing portion 1424 to move toward the first position.

[0093] Specifically, a positioning column 5 is formed on the push-pull body 1423, and the extension direction of the positioning column 5 is parallel to the direction of straight extension from the central axis of the air inlet chamber 115 to the mounting port 117. The pressing portion 1424 is movably arranged on the positioning column 5, and a reset member 150 is arranged between the positioning column 5 and the pressing portion 1424. The reset member 150 is elastically supported between the positioning column 5 and the pressing portion 1424. When the pressing portion 1424 is in the second position, that is, when the pressing portion 1424 is driven to the extreme position toward the side of the air inlet chamber 115, the pressing portion 1424 presses against the reset member 150 to put it in a compressed state. At this time, the first connecting portion 1421 is disconnected from the first connecting matching portion 1412, and the second connecting portion 1422 and the second connecting matching portion 118 can be in a connected state, so as to facilitate pushing the filter element 141 into the air inlet chamber 115 or pulling the filter element 141 out of the air inlet chamber 115 through the push-pull member 142.

[0094] After the pressing part 1424 is released, the reset member 150 resumes its deformation and can move the pressing part 1424 toward the first position, so that the pressing part 1424 can be automatically reset, which facilitates the driving of the pressing part 1424. At the same time, during this process, the first connecting part 1421 can be connected to the first connecting matching part 1412 without the need to drive the pressing part 1424 manually or by other means, thereby improving the connection convenience between the first connecting part 1421 and the first connecting matching part 1412.

[0095] Combine Figure 4 and Figure 6 In some embodiments of the present invention, the second connecting portion 1422 is an elastic snap-fit ​​portion, and the second connecting fitting portion 118 is a snap-fit ​​portion. The elastic snap-fit ​​portion is suitable for being deformed under the stopping action of the push-pull body 1423 to disconnect the elastic snap-fit ​​portion from the snap-fit ​​portion.

[0096] Specifically, the second connecting portion 1422 is constructed as an elastic snap-fit ​​portion formed on the pressing portion 1424, and the second snap-fitting portion is constructed as a snap-fitting portion formed on the outer shell 110. For example, the elastic snap-fitting portion can be constructed as an elastic hook, and the snap-fitting portion can be a snap-fitting protrusion. In the direction extending straight along the rotation center line of the first wind shield 121 to the mounting port 117, the second connecting portion 1422 can be opposite to and connected to the second connecting fitting portion 118, thereby connecting and fixing the push-pull member 142 to the outer shell 110.

[0097] Furthermore, in the process of driving the pressing part 1424 from the first position to the second position, the push-pull body 1423 can press against the second connecting part 1422 to deform the second connecting part 1422. After the deformation, the second connecting part 1422 can be misaligned with the second connecting matching part 118 and disconnected, thereby disconnecting the push-pull member 142 from the shell 110, making it easier to remove the push-pull member 142 from the shell 110.

[0098] Combine Figure 4 、 Figure 6 、 Figure 9 as well as Figure 10 In some embodiments of the present invention, the push-pull body 1423 defines a mounting cavity 1425 having a first opening 1426 , and the pressing portion 1424 is disposed in the mounting cavity 1425 and partially exposed from the first opening 1426 .

[0099] Specifically, an installation cavity 1425 is defined on the push-pull body 1423, the positioning column 5 is arranged in the installation cavity 1425, the pressing portion 1424 is arranged on the positioning column 5 and the pressing portion 1424 can move relative to the installation cavity 1425, the first opening 1426 is arranged opposite to the positioning column 5, and a portion of the pressing portion 1424 can be exposed from the first opening 1426 to facilitate pressing the pressing portion 1424.

[0100] In some examples, such as Figure 6 As shown, in the first position, the elastic engaging portion at least partially passes through the second opening 1427 to engage with the engaging engaging portion, as shown in FIG. Figure 8 As shown, in the state of the second position, the elastic clamping portion is deformed under the stopping action of the hole wall of the second opening 1427 so that the elastic clamping portion is disconnected from the clamping fitting portion.

[0101] Specifically, the installation cavity 1425 also has a second opening 1427, which can be used to allow at least part of the elastic clamping portion (i.e., the second connecting portion 1422) to pass through, and the hole wall of the second opening 1427 can be used to press against the elastic clamping portion to cause it to deform.

[0102] In which, in the first position, the elastic snap-fit ​​portion at least partially protrudes from the second opening 1427 to cooperate with the snap-fit ​​portion. For example, the entire elastic snap-fit ​​portion or the end portion close to the second opening 1427 can protrude from the second opening 1427, and in this state, the elastic snap-fit ​​portion can be arranged relative to the snap-fit ​​portion, and the elastic snap-fit ​​portion can be abutted or connected with the snap-fit ​​portion, so that the push-pull member 142 can be connected to the housing 110.

[0103] During the process of the pressing part 1424 moving from the first position to the second position, the hole wall of the second opening 1427 can press against the elastic clamping part to deform it, and when the pressing part 1424 is completely in the second position, the elastic clamping part undergoes maximum deformation. At this time, the elastic clamping part and the clamping fit are misaligned to disconnect, and the push-pull member 142 and the shell 110 can be separated.

[0104] Reference Figure 10 In some embodiments of the present invention, the wall of the second opening 1427 has a guide surface 1428 that extends obliquely from the inside of the installation cavity 1425 to the outside of the installation cavity 1425 toward the snap-fit ​​portion.

[0105] Specifically, the guide surface 1428 is formed on a side hole wall of the second opening 1427 relatively close to the air inlet chamber 115. In the direction extending from the first position to the second position, the cross-sectional area of ​​the hole wall where the guide surface 1428 is located gradually increases, that is, the guide surface 1428 extends obliquely from inside the installation cavity 1425 to outside the installation cavity 1425 toward the direction close to the snap-fitting part.

[0106] Furthermore, in the process of the pressing part 1424 moving from the first position to the second position, the guide surface 1428 can guide the elastic clamping part, and the guide surface 1428 can press the elastic clamping part to make it gradually deform along the outside of the installation cavity 1425 toward the inside of the installation cavity 1425, so that the elastic clamping part can be disconnected from the clamping fitting part. Among them, by setting the guide surface 1428, it is helpful to prevent the elastic clamping part from being stuck with the hole wall of the second opening 1427, and it is helpful to ensure the effect of the hole wall of the second opening 1427 pressing the elastic clamping part to deform.

[0107] Combine Figure 8 and Figure 9 In some embodiments of the present invention, one of the first connection portion 1421 and the first connection matching portion 1412 is a sliding groove extending along a preset direction with one end closed and the other end open, and one of the first connection portion 1421 and the first connection matching portion 1412 is a slider.

[0108] Specifically, one of the first connection portion 1421 and the first connection matching portion 1412 can be configured as a slide groove, and one end of the slide groove is open and the other end is closed. The other of the first connection portion 1421 and the first connection matching portion 1412 can be configured as a slider. The slider can slide in the slide groove to achieve movably connected between the first connection portion 1421 and the first connection matching portion 1412, and the filter element 141 can rotate relative to the push-pull member 142. When the slider is located in the slide groove, the slider is connected to the slide groove, so that the filter element 141 is connected to the push-pull member 142.

[0109] Furthermore, one end of the slide groove is open, and the slider can slide out of the slide groove through the open end of the slide groove to realize the detachable connection between the first connecting portion 1421 and the first connecting matching portion 1412, so that the filter element 141 can be separated from the push-pull member 142, which is convenient for replacing the filter element 141 separately. In addition, after the slider slides out of the slide groove, the filter element 141 and the first wind shield member 121 can continue to rotate, which is beneficial to increase the rotation range of the first wind shield member 121.

[0110] The other end of the chute is closed, which helps to ensure that the filter element 141 is connected to the push-pull member 142 through the chute and the slider, and prevents the filter element 141 from being separated from the push-pull member 142 due to the disengagement of the slider from the chute.

[0111] Among them, the slide groove can be constructed as an arc groove, and the circle where the arc groove is located is concentric with the circle formed by the rotation arc of the filter element 141 and the first wind shield 121. The slider can be constructed as an arc to ensure the sliding cooperation effect of the slider and the slide rail, which is conducive to ensuring the smoothness of the rotation of the filter element 141 driven by the first wind shield 121.

[0112] It can be understood that the first connection part 1421 can be constructed as a slide groove, and the first connection matching part 1412 can be constructed as a slider; or the first connection part 1421 can be constructed as a slider, and the first connection matching part 1412 can be constructed as a slide groove. The technical effects achieved by the above two structures are the same, and they will not be elaborated here one by one. The specific structure of the first connection part 1421 and the first connection matching part 1412 is not specifically limited here, as long as the matching effect of the first connection part 1421 and the first connection matching part 1412 is guaranteed.

[0113] When the filter assembly 140 is in the initial state of being installed in the shell 110 and in the process of being removed from the installation port 117, the filter element 141 and the push-pull element 142 are connected to the slide groove through a slider, and when the first wind shield 121 drives the filter element 141 to rotate, the slide groove and the slider slide in cooperation.

[0114] When the filter element 141 is in the initial state where the housing 110 is installed in place, that is, when the filter element 141 has just been installed in the air inlet chamber 115 through the push-pull member 142, the slider is located in the slide groove and the two are connected, so that the filter element 141 and the push-pull member 142 are in a connected state; when the filter element 141 needs to be pulled out of the air inlet chamber 115, the slider needs to be located in the slide groove so that the filter element 141 can be connected to the push-pull member 142, so that the filter element 141 can be pulled out of the air inlet chamber 115 through the push-pull member 142; when the first wind shield 121 drives the filter element 141 to rotate, the slide groove and the slider slide together, so that the filter element 141 can rotate relative to the push-pull member 142, thereby preventing the push-pull member 142 from interfering with the rotation of the filter element 141 and the first wind shield 121.

[0115] Combine Figure 5 、 Figure 7 、 Figure 9 and Figure 11 In some embodiments of the present invention, the pressing portion 1424 further has a stop portion 1429. When the pressing portion 1424 is in the first position, the stop portion 1429 opens the open mouth 1430 at one end of the slide groove to allow the slider to slide out of the slide groove. When the pressing portion 1424 is in the second position, the stop portion 1429 stops at the open mouth 1430 at one end of the slide groove to prevent the slider from sliding out.

[0116] Specifically, the pressing portion 1424 is provided with a stop portion 1429, and the pressing portion 1424 can drive the stop portion 1429 to move. The stop portion 1429 and the elastic clip portion are spaced apart in a direction parallel to the rotation center line of the first wind shield 121, and the stop portion 1429 is arranged closer to the slide groove than the elastic clip portion.

[0117] When the pressing portion 1424 is in the first position, the stop portion 1429 is offset from the open end of the slide slot so that the open mouth 1430 at the open end of the slide slot can be opened, and the slider can slide out of the slide slot to ensure the rotation of the first wind shield 121 and the filter element 141. When the pressing portion 1424 gradually moves from the first position to the second position, the pressing portion 1424 drives the stop portion 1429 to move toward the open end of the slide slot.

[0118] When the pressing portion 1424 is in the second position, the stop portion 1429 is opposite to the open end of the slide groove, and the stop portion 1429 can close the open mouth 1430 of the open end of the slide groove to fix the slider in the slide groove and keep the slider connected to the slide groove, thereby ensuring the connection reliability between the filter element 141 and the push-pull member 142, and further preventing the slide groove from being separated from the slider, causing the filter element 141 to be separated from the push-pull member 142.

[0119] Combine Figure 9 and Figure 10 In some embodiments of the present invention, the push-pull body 1423 includes: a handle 1 and a gripping portion 2, wherein one end of the handle 1 in the length direction has a buckle portion 3 to cooperate with the mounting port 117; the gripping portion 2 is connected to the other end of the handle 1 in the length direction.

[0120] Specifically, one end of the handle 1 is connected to the filter element 141, and the other end of the handle 1 is spaced apart from the filter element 141 to facilitate elastic deformation of the handle 1, wherein the end of the handle 1 connected to the filter element 141 is defined as the fixed end of the handle 1, and the end of the handle 1 spaced apart from the filter element 141 is defined as the free end of the handle 1. In the process of pushing and pulling the main body 1423 to cooperate with the mounting port 117, the buckle portion 3 is abutted against the side wall of the outer shell 110 facing away from the air inlet chamber 115 (that is, the outer wall of the outer shell 110), and the handle 1 can be elastically deformed by pressing, so that the handle 1 can be embedded in the mounting port 117 and close the mounting port 117.

[0121] At the same time, the buckle portion 3 can be embedded in the installation opening 117, and the buckle portion 3 can be engaged with the side wall of the outer shell 110 close to the air inlet chamber 115 (that is, the inner wall of the outer shell 110) to prevent the handle 1 from falling out of the installation opening 117, thereby ensuring the assembly stability of the handle 1 and the reliability of the handle 1 closing the installation opening 117.

[0122] Furthermore, a gripping portion 2 is provided at the fixed end of the handle 1, and the gripping portion 2 can be used to drive the push-pull body 1423 as a whole, and the push-pull body 1423 drives the filter element 141 to install the filter element 141 into the air inlet chamber 115 or remove the filter element 141 from the air inlet chamber 115. Among them, the gripping portion 2 is provided at the fixed end of the handle 1, which can effectively prevent the handle 1 from elastically deforming during the pushing and pulling process, thereby ensuring the effective pushing and pulling of the filter element 141, and preventing the handle 1 from deforming during the pushing and pulling process, which may result in the filter element 141 being unable to be moved or the movement effect of the filter element 141 being poor.

[0123] Combine Figure 2 、 Figure 9 and Figure 10 The slide groove is provided on the side of the handle 1 facing away from the grip portion 2 and extends along the length direction of the handle 1 , and the pressing portion 1424 is movably provided on the handle 1 .

[0124] Specifically, the slide groove is arranged on the side of the handle 1 relatively close to the air inlet chamber 115, and the slide groove extends in an arc shape along the length direction of the handle 1. The grip portion 2 is arranged on the side of the handle 1 away from the air inlet chamber 115, and the grip portion 2 can jointly define an installation cavity 1425 with the handle 1. The hand can be inserted into the installation cavity 1425 and a driving force can be applied to the grip portion 2, thereby driving the push-pull body 1423 to move as a whole through the grip portion 2.

[0125] The first opening 1426 is formed on the grip portion 2 , and the positioning post 5 is provided on a portion of the handle 1 located within the mounting cavity 1425 . The pressing portion 1424 is movably mounted on the handle 1 through the first opening 1426 and the positioning post 5 .

[0126] In other examples, the pressing portion 1424 can be movably provided on the grip portion 2, that is, the positioning column 5 can be formed on the grip portion 2, and the pressing portion 1424 is installed on the grip portion 2 through the positioning column 5. When the user grasps the grip portion 2 with one hand, the finger can press the pressing portion 1424 at the same time, so that the user can operate with one hand, thereby improving the convenience of operation.

[0127] Combine Figure 9 and Figure 10 In some embodiments of the present invention, the buckle portion 3 is formed with a buckle inclined surface 31 extending from the outside of the installation opening 117 to the inside of the installation opening 117 and toward a direction away from the fixed end.

[0128] Specifically, the buckle portion 3 is arranged on the side of the free end of the handle 1 away from the fixed end, and a buckle slope 31 is formed on the side of the buckle portion 3 away from the fixed end. In the direction extending from the fixed end to the free end, the distance between the buckle slope 31 and the filter element 141 gradually decreases, and the cross-sectional area of ​​the buckle portion 3 gradually decreases, so that the buckle portion 3 is not easy to fall off from the installation port 117.

[0129] During the process of installing the filter element 141 into the air inlet chamber 115, the buckle portion 3 abuts against the outer shell 110, and the handle 1 is pressed to elastically deform toward the side of the air inlet chamber 115, so that the buckle portion 3 (which can also be understood as the handle 1 as a whole) can be embedded in the installation opening 117, and the handle 1 restores its elastic deformation after being embedded in the installation opening 117, and the buckle inclined surface 31 of the buckle portion 3 abuts against the inner wall surface of the outer shell 110 to prevent the handle 1 from falling out of the installation opening 117.

[0130] In some embodiments of the present invention, a stop portion 4 is provided on the handle 1, and the stop portion 4 protrudes from at least one side of the handle 1. When the handle 1 is partially embedded in the mounting opening 117 and the mounting opening 117 is closed, the stop portion 4 stops against the outer wall surface of the shell 110.

[0131] Specifically, a stop portion 4 is provided on the side of the handle 1 facing away from the filter element 141, and the stop portion 4 protrudes from at least one side of the handle 1 in the width direction of the handle 1. A portion of the handle 1 can be embedded in the mounting opening 117 and close the mounting opening 117. When the handle 1 closes the mounting opening 117, the stop portion 4 is engaged with the outer wall surface of the shell 110 to prevent the handle 1 from being further embedded in the air inlet chamber 115 and interfering with the operation of other components in the air inlet chamber 115.

[0132] It should be noted that the stop portion 4 can be provided on one side of the handle 1 protruding from the handle 1 in the width direction thereof to facilitate the processing of the handle 1; or the stop portion 4 can be provided on both sides of the handle 1 protruding from the handle 1 in the width direction thereof, and the stop portions 4 on both sides of the handle 1 can both stop against the outer wall surface of the shell 110 to prevent the handle 1 from shifting.

[0133] Of course, it is understandable that the specific arrangement of the stop portion 4 on the handle 1 can be determined according to actual production requirements and is not specifically limited here.

[0134] The following briefly describes the installation and removal process of the filter element 141 in the present invention with reference to the embodiment shown in the drawings.

[0135] When the filter element 141 needs to be installed in the air inlet chamber 115: first, the first connecting portion 1412 on the filter element 141 is connected to the first connecting portion 1421 on the push-pull member 142, that is, the slider slides into the slide groove, and then the pressing portion 1424 is pressed to move the pressing portion 1424 from the first position to the second position. At this time, the pressing portion 1424 compresses the reset member 150, and at the same time, the pressing portion 1424 drives the stopper 1429 to move, so that the stopper 1429 closes the open end 1430 of the slide groove, thereby To achieve the connection between the filter element 141 and the push-pull member 142, during the movement of the pressing portion 1424, the hole wall of the second opening 1427 presses against the second connecting portion 1422 (i.e., the elastic clamping portion) to deform it, and then the filter element 141 is pushed into the air inlet chamber 115 from the mounting port 117 through the push-pull member 142. After the filter element 141 enters the air inlet chamber 115, the plug-in portion 1411 of the filter element 141 is plug-fitted with the plug-in fitting portion 1211 of the first wind shield member 121, so that the filter element 141 is connected to the first wind shield member 121.

[0136] Furthermore, when the plug-in fitting portion 1211 and the plug-in fitting portion 1411 are fully mated, the push-pull member 142 closes the installation opening 117, and the pressing portion 1424 can be released at this time. The reset member 150 drives the pressing portion 1424 to move from the second position to the first position, and the pressing portion 1424 drives the stop portion 1429 to move, so that the stop portion 1429 opens the open opening 1430 of the slide groove. When the first wind shield 121 rotates, it can drive the filter element 141 to rotate. At the same time, during the process of the pressing portion 1424 moving from the second position to the first position, the second connecting portion 1422 (i.e., the elastic snap-fitting portion) recovers its deformation and passes through the second opening 1427. The second connecting portion 1422 can be connected to the second connecting fitting portion 118 (i.e., the snap-fitting portion) on the outer shell 110, thereby realizing the connection between the push-pull member 142 and the outer shell 110, preventing the push-pull member 142 from falling out of the installation opening 117, thereby completing the installation of the filter assembly 140.

[0137] When the filter element 141 needs to be pulled out from the air inlet chamber 115, the first connecting portion 1421 is connected to the first connecting matching portion 1412, that is, the slider is located in the slide groove to realize the connection between the filter element 141 and the push-pull member 142, and the pressing portion 1424 is pressed to move it from the first position to the second position. During the movement of the pressing portion 1424, the hole wall of the second opening 1427 presses against the second connecting portion 1422 (that is, the elastic clamping portion) to disconnect it from the second connecting matching portion 118 (that is, the clamping portion), thereby making the push-pull member 141 2 is disconnected from the housing 110, and at the same time, the pressing portion 1424 drives the stopping portion 1429 to move toward the opening 1430 of the open end of the slide slot. When the pressing portion 1424 moves to the second position, the stopping portion 1429 closes the opening 1430 of the open end of the slide slot to ensure the reliability of the connection between the filter element 141 and the push-pull member 142. Then, the filter element 141 can be pulled by the push-pull member 142 to disengage the plug-in portion 1411 from the plug-in mating portion 1211, thereby allowing the filter element 141 to be removed from the air inlet chamber 115.

[0138] Combine Figure 1 and Figure 12 In some embodiments of the present invention, the first wind shield 121 includes: a partition plate 1212, the partition plate 1212 is arranged in the outer shell 110, the air inlet cavity 115 and the wind wheel 130 are located on opposite sides of the partition plate 1212, and a connecting port 1213 is provided on the partition plate 1212 to connect the air inlet cavity 115 and the wind wheel cavity 116.

[0139] Specifically, the partition plate 1212 is arranged in the outer shell 110, and the partition plate 1212 can divide the inner cavity of the outer shell 110 into an air inlet chamber 115 and a wind wheel chamber 116.

A connecting port 1213 is provided on the partition chamber, and the air inlet chamber 115 and the wind wheel chamber 116 are connected through the connecting port 1213.

[0140] The first wind shield 121 further includes a wind shield plate 1214 , which is rotatably disposed in the air inlet cavity 115 , and the wind shield plate 1214 can selectively block the fresh air inlet 111 or the indoor air inlet 112 .

The wind shield 1214 can be rotatably arranged in the air inlet cavity 115 to selectively block the fresh air inlet 111 or the indoor air inlet 112, and the fresh air inlet 111 and the indoor air inlet 112 are spaced apart in the circumferential direction of the air inlet cavity 115 to facilitate the wind shield 1214 to selectively open and close the fresh air inlet 111 or the indoor air inlet 112.

[0142] Among them, the partition plate 1212 and the wind shield 1214 are integrally formed, or the partition plate 1212 and the wind shield 1214 are separately formed and mechanically connected together to achieve synchronous rotation, and the filter element 141 is detachably connected to the partition plate 1212 or the wind shield 1214 and the filter element 141 is in contact with the partition plate 1212.

[0143] In some embodiments, the partition plate 1212 and the wind shield member can be integrally formed so that the partition plate 1212 can rotate synchronously with the wind shield plate 1214 .

[0144] In other embodiments, the partition plate 1212 and the wind shield plate 1214 may be separately formed and connected, so that the partition plate 1212 and the wind shield plate 1214 can rotate synchronously.

[0145] Among them, the plug-in fitting part 1211 is arranged on the partition plate 1212, and the plug-in fitting part 1211 is arranged close to the partition plate 1212, and the plug-in part 1411 is arranged on the filter element 141, and the plug-in fitting part 1411 is plug-fitted with the plug-in fitting part 1211 to detachably connect the filter element 141 to the first wind shield member 121, and since the plug-in fitting part 1211 is arranged close to the partition plate 1212, when the plug-in fitting part 1411 is plug-fitted with the plug-in fitting part 1211, the filter element 141 can be fitted with the partition plate 1212, thereby eliminating the axial movement gap between the filter element 141 and the partition plate 1212, preventing air leakage caused by the axial gap between the filter element 141 and the first wind shield member 121, which is beneficial to increasing the air volume of the fresh air module 100.

[0146] Combine Figure 1 and Figure 4 In some embodiments of the present invention, the outdoor air outlet 114 and the indoor air outlet 113 are arranged circumferentially of the wind wheel cavity 116, and the second wind shield 122 is rotatably provided in the wind wheel cavity 116 to selectively open and close the indoor air outlet 113 and the outdoor air outlet 114.

[0147] Specifically, the outdoor air outlet 114 and the indoor air outlet 113 are arranged in the circumferential direction of the wind wheel cavity 116. The airflow entering the wind wheel cavity 116 can be discharged into the external space through the outdoor air outlet 114 or the indoor air outlet 113, and the outdoor air outlet 114 and the indoor air outlet 113 are spaced apart in the circumferential direction of the wind wheel cavity 116 so that the second wind shield 122 can selectively open and close the outdoor air outlet 114 and the indoor air outlet 113.

[0148] In some embodiments of the present invention, the first wind shield 121 and the second wind shield 122 are integrally formed; or, the first wind shield 121 and the second wind shield 122 are separately formed and mechanically connected together; or, the first wind shield 121 and the second wind shield 122 are relatively rotatable.

[0149] Optionally, the first wind shield 121 and the second wind shield 122 can be integrally formed so that the first wind shield 121 and the second wind shield 122 can move synchronously; or the first wind shield 121 and the second wind shield can be processed and formed separately, by connecting the first wind shield 121 and the second wind shield 122 so that the first wind shield 121 and the second wind shield 122 can move synchronously, and by driving one of the first wind shield 121 and the second wind shield, the opening and closing states of different air inlets and outlets can be switched at the same time, which is convenient for driving the first wind shield 121 and the second wind shield 122. At the same time, there is no need to set up driving structures for driving the first wind shield 121 and the second wind shield 122 separately, which is conducive to simplifying the component settings of the fresh air module 100, reducing the production cost of the fresh air module 100, and at the same time helping to reduce the volume of the fresh air module 100 and realize the miniaturization setting of the fresh air module 100.

[0150] Or the first wind shield 121 and the second wind shield 122 can be formed separately, and the second wind shield 122 can be rotatably arranged on the side of the partition plate 1212 away from the wind shield plate 1214, so that the second wind shield 122 can rotate relative to the first wind shield 121, which is beneficial to increase the achievable working modes of the fresh air module 100 and improve the functionality of the fresh air module 100.

[0151] In some embodiments of the present invention, the fresh air module 100 has a fresh air mode and an exhaust mode; in the fresh air mode, the first wind shield 121 opens the fresh air inlet 111 and closes the indoor air inlet 112, and the second wind shield 122 opens the indoor air outlet 113 and closes the outdoor air outlet 114; in the exhaust mode, the first wind shield 121 opens the indoor air inlet 112 and closes the fresh air inlet 111, and the second wind shield 122 opens the outdoor air outlet 114 and closes the indoor air outlet 113.

[0152] Specifically, in the exhaust mode, the wind shield 1214 rotates to the fresh air inlet 111 to close the fresh air inlet 111, and at the same time opens the indoor air inlet 112. The second wind shield 122 rotates to the indoor air outlet 113 to close the indoor air outlet 113, and at the same time opens the outdoor air outlet 114. The indoor air inlet 112 is connected to the indoor space, and the outdoor air outlet 114 is connected to the outdoor space. Indoor air can enter the fresh air module 100 through the indoor air inlet 112 and be discharged into the outdoor space through the outdoor air outlet 114, realizing the function of the fresh air module 100 to exhaust air to the outdoors, which can also be understood as realizing the negative pressure fresh air function of the fresh air module 100.

[0153] In the fresh air mode, the wind shield 1214 rotates to the indoor air inlet 112 to close the indoor air inlet 112, and at the same time opens the fresh air inlet 111.

The fresh air inlet 111 is connected to the outdoor space, and the indoor air outlet 113 is connected to the indoor space. The fresh air outside can enter the fresh air module 100 through the fresh air inlet 111 and be discharged into the indoor space through the indoor air outlet 113, realizing the function of the fresh air module 100 to supply fresh air to the indoor room, which can also be understood as realizing the positive pressure fresh air function of the fresh air module 100.

[0154] In some embodiments of the present invention, when the first wind shield 121 and the second wind shield 122 are relatively rotatable, the fresh air module 100 also has a purification mode. In the purification mode, the first wind shield 121 rotates to the fresh air inlet 111 to close the fresh air inlet 111, and at the same time, the indoor air inlet 112 is opened. The second wind shield 122 rotates to the outdoor air outlet 114 to close the outdoor air outlet 114, and at the same time, the indoor air outlet 113 is opened. The indoor foul air can enter the air inlet chamber 115 through the indoor air inlet 112, and the airflow formed by the indoor foul air flows through the filter element 141 and then enters the wind wheel chamber 116. Among them, when the airflow flows through the filter element 141, the filter element 141 can filter the airflow to purify the indoor foul air. The purified airflow is discharged into the indoor space through the indoor air outlet 113 in the wind wheel chamber 116, realizing the purification effect of the fresh air module 100 on the indoor air and improving the air quality of the indoor air.

[0155] The fresh air module 100 according to the present invention further includes a driving device, which is connected to the rotating assembly 120 via a transmission mechanism to drive the rotating assembly 120 to rotate.

[0156] Specifically, when the first wind shield 121 and the second wind shield 122 rotate synchronously, the fresh air module 100 can be provided with a set of driving devices and transmission mechanisms, and the driving device can be connected to one of the first wind shield 121 or the second wind shield 122 through the transmission mechanism. The driving device drives one of the first wind shield 121 and the second wind shield 122 to rotate, so that the first wind shield 121 and the second wind shield 122 rotate synchronously.

[0157] When the first wind shield 121 and the second wind shield 122 rotate respectively, the fresh air module 100 can be provided with two groups of drive group drive devices and transmission mechanisms, one group of drive devices and transmission mechanisms in the two groups is used to be connected to the first wind shield 121 for transmission, and the other group of drive devices and transmission mechanisms in the two groups is used to be connected to the second wind shield 122 for transmission, so as to drive the first wind shield 121 and the second wind shield 122 to rotate respectively.

[0158] The transmission mechanism may be configured as a rack and pinion transmission mechanism.

[0159] The air conditioner according to the present invention includes the above-mentioned fresh air module 100 .

[0160] Since the air conditioner is provided with the above-mentioned fresh air module 100, by setting the rotating component 120, the opening and closing states of different air inlets and outlets can be flexibly adjusted, which is conducive to increasing the air supply modes that the fresh air module 100 can achieve, improving the functionality of the fresh air module 100, and there is no need to set structures such as air valves, which is conducive to simplifying the component settings of the fresh air module 100, reducing the production cost of the fresh air module 100, and realizing the miniaturization design of the fresh air module 100. In addition, by setting the filter component 140, the purification function of the fresh air module 100 on the air flow can be realized, further improving the fresh air module 100. The functionality of the wind module 100 facilitates the positioning and installation of the filter 141 by connecting the filter 141 to the first wind shield 121, and there is no need to set an additional structure for installing the filter 141 in the shell 110, so as to further simplify the structure of the fresh air module 100. At the same time, the filter 141 can rotate synchronously with the first wind shield 121 to prevent the filter 141 from interfering with the rotation of the first wind shield 121, thereby ensuring the rotation effect of the first wind shield 121, which is beneficial to ensure the opening and closing effect of the first wind shield 121 on the fresh air inlet 111 and the indoor air inlet 112.
