Description

Technical Field

[0001] This invention relates to the field of air filtration technology, and in particular to a fresh air filter support and a fan. Background Technology

[0002] Currently, many air conditioners have a fresh air filtration function. For example, an air conditioner has a fan structure installed inside, and when air enters the room, the air conditioner filters the air through the fresh air filter bracket. However, when the fan stops running and there are no other valves blocking the fan's air intake duct, if the indoor air pressure is lower than the outdoor air pressure, outdoor air will enter the room through the fan's air intake duct, reducing the user experience. Summary of the Invention

[0003] One objective of the first aspect of the present invention is to overcome at least one technical defect in the prior art and to provide a fresh air filter support and a fan.

[0004] One object of the present invention is to provide a fresh air filter holder that can prevent airflow when not in use.

[0005] Specifically, the present invention provides a fresh air filter holder, comprising:

[0006] Two opposing first baffles, each having at least one set of opposing fixing holes on its opposing side;

[0007] At least one windproof component, the number of windproof components corresponding one-to-one with the number of sets of fixing holes, the windproof component including: a windproof plate, the two ends of which are respectively formed with opposing insertion portions, the insertion portions being rotatably inserted into their corresponding fixing holes;

[0008] The wind deflector is configured to rotate in the corresponding fixing hole along the opening or closing direction via the plug portion to open or close the area between the two first baffles.

[0009] Optionally, the windbreak assembly further includes at least one first anti-rotation block, fixed to one side of the two first baffles opposite to each other;

[0010] The first anti-rotation block is configured to abut against the wind deflector when the wind deflector is in the open state, preventing the wind deflector from rotating in a closing direction under the action of gravity.

[0011] Optionally, the windbreak assembly further includes at least one second anti-rotation block, fixed on one side of the two first baffles opposite to each other, and arranged along the length direction of the first baffles with the first anti-rotation block;

[0012] The second anti-rotation block is configured to prevent the wind deflector from rotating in an opening direction when the wind deflector is in the closed state.

[0013] Optionally, the windbreak assembly further includes at least one third anti-rotation block, which is arranged along the width direction of the first baffle with the second anti-rotation block;

[0014] The fixing hole extends along the length of the first baffle so that when the wind deflector rotates in the closing direction, the insertion part moves along the length of the fixing hole, and one long edge of the wind deflector is stuck between the third anti-rotation block and the second anti-rotation block;

[0015] The third anti-rotation block is configured to prevent the wind deflector from rotating in the other opening direction when the wind deflector is in the closed state.

[0016] Optionally, the third anti-rotation block and the second anti-rotation block are at different distances from the surfaces of the plug-in portion to the plug-in portion;

[0017] When the wind deflector rotates in the closing direction, the distance from the surface of the third anti-rotation block and the second anti-rotation block that is first passed by the wind deflector to the insertion part is larger.

[0018] Optionally, the surface of the third anti-rotation block and the second anti-rotation block that is first passed by the wind deflector and faces the insertion portion is an inclined surface, so that the wind deflector slides along the inclined surface between the third anti-rotation block and the second anti-rotation block.

[0019] Optionally, the insertion portion is located near the length edge of its end;

[0020] The first anti-rotation block is located on one side of the insertion portion along the length direction of the first baffle, and when the wind deflector is in the open state, it abuts against the area between the long edge of the wind deflector near the insertion portion and the insertion portion; or

[0021] The first anti-rotation block is located on the other side of the insertion part along the length direction of the first baffle, and when the wind deflector is in the open state, it abuts against the area between the length edge of the wind deflector away from the insertion part and the insertion part.

[0022] Optionally, one of the two first baffles has a first recessed area and a second recessed area at both ends of the side without the fixing hole along the length direction, which are recessed toward the side with the fixing hole to serve as a handle.

[0023] The edges of the surfaces having the first recessed region and the second recessed region extend outward to form a flange.

[0024] Optionally, the number of fixing holes is multiple, and the fixing holes on the first baffle are arranged sequentially along the length direction of the first baffle.

[0025] According to another aspect of the present invention, the present invention also provides a fan, comprising:

[0026] The fan body has a plug-in interface at its air inlet;

[0027] The fresh air filter bracket described in any of the above embodiments can be detachably inserted into the insertion interface.

[0028] The fresh air filter bracket of the present invention may include two opposing first baffles and at least one wind-blocking component. Each of the two first baffles has at least one set of opposing fixing holes on its opposing side. The wind-blocking component includes a wind-blocking plate, with opposing insertion portions formed at both ends along its length. The insertion portions are rotatably inserted into their corresponding fixing holes. The wind-blocking plate rotates in the corresponding fixing holes along an opening or closing direction through the insertion portions to open or close the area between the two first baffles, thereby allowing or blocking air from passing through the fresh air filter bracket as needed. This structural design is very simple. Furthermore, the wind-blocking component and the first baffles can form an integral structure, preventing the wind-blocking component from being lost.

[0029] Furthermore, when the wind deflector is in the open state, it may rotate towards the closing direction under the influence of gravity. The function of the first anti-rotation block is precisely to prevent the wind deflector from rotating towards the closing direction under the influence of gravity, thereby preventing the wind deflector from closing. Specifically, for example, the first anti-rotation block can be located between the insertion part and one end of the first baffle along its length, so that when the wind deflector is in the open state, the first anti-rotation block can be located between one end of the wind deflector and one end of the first baffle along its length; or, the first anti-rotation block can be located between the insertion part and the other end of the first baffle along its length, so that when the wind deflector is in the open state, the first anti-rotation block can be located between the other end of the wind deflector and one end of the first baffle along its length. In both of the above cases, if it is necessary to close the wind deflector, the positions of one end and the other end along the length of the first baffle can be interchanged, that is, the first baffle can be rotated 180 degrees to interchange the positions of one end and the other end along the length of the first baffle, so that the wind deflector can close under the influence of gravity. Furthermore, in order to make full use of gravity, the two ends of the first baffle along its length can be set vertically, with one end pointing upwards and the other downwards. This way, when the wind deflector needs to be closed, the effect of gravity on the wind deflector can be maximized, and it will automatically close under the action of gravity. This design is very novel and ingenious, and it can flexibly realize the opening and closing of the wind deflector, while reducing the number of steps for users.

[0040] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0041] Figure 1 This is a schematic structural diagram of a fresh air filter support according to an embodiment of the present invention; Figure 2 yes Figure 1 A magnified schematic diagram of region A in the middle. See also... Figure 1 and Figure 2 The fresh air filter bracket 100 generally includes two opposing first baffles 101 and at least one wind-blocking assembly. At least one set of opposing fixing holes 102 are respectively formed on the opposing sides of the two first baffles 101. The number of wind-blocking assemblies corresponds one-to-one with the number of sets of fixing holes 102. Each wind-blocking assembly may include a wind-blocking plate 103, with opposing insertion portions 112 formed at both ends along its length. The insertion portions 112 are rotatably inserted into their corresponding fixing holes 102. The wind-blocking plate 103 is configured to rotate in an opening or closing direction within the corresponding fixing hole 102 via the insertion portions 112 to open or close the area between the two first baffles 101.

[0042] In this embodiment, the fresh air filter bracket 100 can be used to install a filter to filter the passing air. The fixing hole 102 can penetrate the first baffle 101. The fresh air filter bracket 100 may include two opposing first baffles 101 and at least one wind-blocking assembly. At least one set of opposing fixing holes 102 are respectively opened on the opposing sides of the two first baffles 101. The wind-blocking assembly includes a wind-blocking plate 103, with opposing insertion portions 112 formed at both ends along its length. The insertion portions 112 are rotatably inserted into their corresponding fixing holes 102. The wind-blocking plate 103 rotates in the corresponding fixing holes 102 along an opening or closing direction through the insertion portions 112 to open or close the area between the two first baffles 101, thereby allowing or blocking air from passing through the fresh air filter bracket 100 as needed. This structural design is very simple. Furthermore, the wind-blocking assembly and the first baffles 101 can form an integral structure, preventing the loss of the wind-blocking assembly. The effect diagram of the wind deflector 103 rotating in the opening direction through the insertion part 112 in the corresponding fixing hole 102 to open the area between the two first baffles 101 can be found in [reference 112]. Figure 1 The wind deflector 103 is perpendicular to the length edge of the first baffle 101. Rotating the wind deflector 103 in the opening direction can be understood as rotating it in a direction perpendicular to the length edge of the first baffle 101. A diagram illustrating the effect of the wind deflector 103 rotating in the closing direction through the insertion part 112 in the corresponding fixing hole 102 to close the area between the two first baffles 101 can be found here. Figure 4 and Figure 5 The wind deflector 103 is parallel to the length edge of the first baffle 101. The rotation of the wind deflector 103 toward the closing direction can be understood as rotation toward a direction parallel to the length edge of the first baffle 101.

[0043] In one embodiment of the present invention, the windshield assembly may further include at least one first anti-rotation block 104, fixed on one side of the two first baffles 101 facing each other;

[0044] The first anti-rotation block 104 is configured to abut against the wind deflector 103 when the wind deflector 103 is in the open state, preventing the wind deflector 103 from rotating in a closing direction under the action of gravity.

[0045] In this embodiment, the number of first anti-rotation blocks 104 can also be two, respectively fixed to opposite sides of the two first baffles 101. When the wind deflector 103 is in the open state, such as Figure 1 As shown, the wind deflector 103 may rotate in the closing direction under the action of gravity. The function of the first anti-rotation block 104 is to prevent the wind deflector 103 from rotating in the closing direction under the action of gravity, thereby preventing the wind deflector 103 from closing. Specifically, for example, the first anti-rotation block 104 can be located between the insertion part 112 and one end of the first baffle 101 in the length direction, so that when the wind deflector 103 is in the open state, the first anti-rotation block 104 can be located between one end of the wind deflector 103 and the first baffle 101 in the length direction; or, the first anti-rotation block 104 can be located between the insertion part 112 and the other end of the first baffle 101 in the length direction, so that when the wind deflector 103 is in the open state, the first anti-rotation block 104 can be located between the other end of the wind deflector 103 and the first baffle 101 in the length direction. In both of the above cases, if it is necessary to close the wind deflector 103, the positions of one end and the other end of the first baffle 101 along its length can be interchanged. Specifically, the first baffle 101 can be rotated 180 degrees to swap the positions of one end and the other end along its length. This will allow the wind deflector 103 to close under the influence of gravity. The effect of swapping the positions of one end and the other end of the first baffle 101 along its length is as follows: Figure 3 As shown. Furthermore, in order to fully utilize the effect of gravity, the two ends of the first baffle 101 along its length can be set vertically, that is, one end facing upwards and the other end facing downwards. In this way, when it is necessary to close the wind deflector 103, the effect of gravity on the wind deflector 103 can be maximized, and it can automatically close under the action of gravity. This design is very novel and ingenious, which can flexibly realize the opening and closing of the wind deflector 103, reduce the user's operation steps, and improve the user experience.

[0046] In one embodiment of the invention, the insertion portion 112 is located near the length edge of its end. A first anti-rotation block 104 is located on one side of the insertion portion 112 along the length direction of the first baffle 101, and abuts against the area between the long edge of the wind deflector 103 and the insertion portion 112 when the wind deflector 103 is in the open state; or the first anti-rotation block 104 is located on the other side of the insertion portion 112 along the length direction of the first baffle 101, and abuts against the area between the long edge of the wind deflector 103 and the insertion portion 112 when the wind deflector 103 is in the open state.

[0047] In this embodiment, if the insertion part 112 is located at the middle of the end of the wind deflector 103 along its length, the portion of the wind deflector 103 located on both sides of the insertion part 112 may experience equal gravity, making it difficult to control the rotation direction of the wind deflector 103 under gravity, i.e., making it difficult to control the closing direction of the wind deflector 103 under gravity. To avoid the above problem, the insertion part 112 is located near the length edge of its end, such as... Figure 6 As shown, this ensures that the portions of the wind deflector 103 located on both sides of the insertion portion 112 experience different gravitational forces, and makes it easy to determine the rotation direction of the wind deflector 103 under gravity, i.e., easily control the closing direction of the wind deflector 103 under gravity. This further facilitates and accurately determines the position where the first anti-rotation block 104 needs to be fixed. The insertion portion 112 is located near the length edge of its end, fully utilizing the effect of gravity. This design is ingenious and novel. Specifically, when the wind deflector 103 is in the open state, if it is necessary to prevent the wind deflector 103 from changing from the open state to the closed state, the first anti-rotation block 104 only needs to prevent one end of the wind deflector 103 from rotating in the width direction to simultaneously prevent the other end from rotating. Therefore, the first anti-rotation block 104 can be located in multiple different positions. For example, the first anti-rotation block 104 can be located on one side of the insertion portion 112 along the length direction of the first baffle 101 (the length direction of the insertion portion 112 and the first baffle 101). Between the ends), and when the wind deflector 103 is in the open state, it abuts against the area between the long edge of the wind deflector 103 near the insertion portion 112 and the insertion portion 112, or the first anti-rotation block 104 is located on the other side of the insertion portion 112 along the length direction of the first baffle 101 (between the other end of the insertion portion 112 and the other end of the first baffle 101 in the length direction), and when the wind deflector 103 is in the open state, it abuts against the area between the long edge of the wind deflector 103 away from the insertion portion 112 and the insertion portion 112. Furthermore, the advantage of placing the insertion part 112 near the length edge of its end, rather than directly on the length edge of the wind deflector 103, is that when the wind deflector 103 is in the closed state, the insertion parts 112 of adjacent wind deflectors 103 can be prevented from abutting each other. That is, the size and shape of the insertion parts 112 of adjacent wind deflectors 103 do not need to be considered, thereby making it easier for the length edges of adjacent wind deflectors 103 to abut completely. This prevents gaps from forming between adjacent wind deflectors 103 when the wind deflector 103 is in the closed state, and prevents air from passing through the gaps into the fresh air filter support 100.

[0048] In one embodiment of the present invention, the windshield assembly may further include at least one second anti-rotation block 105, which is fixed on the opposite side of the two first baffles 101 and is arranged along the length direction of the first baffles 101 with the first anti-rotation block 104.

[0049] The second anti-rotation block 105 is configured to prevent the wind deflector 103 from rotating in an opening direction when the wind deflector 103 is in the closed state.

[0050] In this embodiment, the second anti-rotation block 105 and the first anti-rotation block 104 can be fixed on the same first baffle 101 or on different first baffles 101. There can also be two second anti-rotation blocks 105, fixed opposite to each other on opposite sides of the two first baffles 101. After the wind deflector 103 rotates from the open state to the fully closed state, it may continue to rotate due to inertia or other factors, i.e., rotate in the opening direction again. To avoid this, the second anti-rotation block 105 is fixed on opposite sides of the two first baffles 101 and arranged along the length of the first baffle 101 with the first anti-rotation block 104. When the wind deflector 103 is in the closed state, it abuts against the wind deflector 103, preventing the wind deflector 103 from continuing to rotate in the opening direction after rotating from the open state to the fully closed state. This allows the wind deflector 103 to quickly stabilize in the fully closed state, effectively blocking air from passing through the fresh air filter bracket 100.

[0051] In one embodiment of the present invention, the windshield assembly may further include at least one third anti-rotation block 106, which is arranged along the width direction of the first baffle 101 with the second anti-rotation block 105.

[0052] The fixing hole 102 extends along the length direction of the first baffle 101 so that when the wind deflector 103 rotates in the closing direction, the insertion part 112 moves along the length direction of the fixing hole 102, so that one long edge of the wind deflector 103 is stuck between the third anti-rotation block 106 and the second anti-rotation block 105.

[0053] The third anti-rotation block 106 is configured to prevent the wind deflector 103 from rotating in the other opening direction when the wind deflector 103 is in the closed state.

[0054] In this embodiment, the second anti-rotation block 105, the first anti-rotation block 104, and the third anti-rotation block 106 can be fixed on the same first baffle 101 or on different first baffles 101. There can also be two third anti-rotation blocks 106, fixed opposite to each other on opposite sides of the two first baffles 101. Because the wind deflector 103 can be opened by rotating in two different opening directions and closed by rotating in two different closing directions, when the wind deflector 103 needs to remain closed, to prevent it from rotating in another opening direction, the third anti-rotation block 106 and the second anti-rotation block 105 are arranged along the width direction of the first baffle 101, so that one long edge of the wind deflector 103 is wedged between the third anti-rotation block 106 and the second anti-rotation block 105. This effectively avoids the aforementioned problem and improves the user experience.

[0055] In one embodiment of the present invention, the third anti-rotation block 106 and the second anti-rotation block 105 are at different distances from the surfaces of the plug-in portion 112 to the plug-in portion 112.

[0056] When the wind deflector 103 rotates in the closing direction, the distance from the surface of the third anti-rotation block 106 and the second anti-rotation block 105 that is first passed by the wind deflector 103 to the insertion part 112 is larger.

[0057] In this embodiment, for example, see Figure 3 When the wind deflector 103 rotates in the closing direction, it must first pass the third anti-rotation block 106. The distance from the surface of the third anti-rotation block 106 facing the insertion part 112 to the insertion part 112 is relatively large. Since the distances from the surfaces of the third anti-rotation block 106 and the second anti-rotation block 105 facing the insertion part 112 to the insertion part 112 are different, when the wind deflector 103 rotates in the closing direction, if the surface of the first of the two anti-rotation blocks (106 and 105) passed by the wind deflector 103 has a smaller distance from the insertion part 112, the first one passed by the wind deflector 103 may obstruct the user's view, making it difficult to determine whether the wind deflector 103 has rotated to the third anti-rotation block. The position between block 106 and the second anti-rotation block 105 is such that the distance from the surface of the first anti-rotation block 106 and the second anti-rotation block 105 that is passed by the wind deflector 103 to the insertion part 112 is larger. This makes it easy to confirm whether the wind deflector 103 has rotated to the position between the third anti-rotation block 106 and the second anti-rotation block 105 when the wind deflector 103 is closed, thereby stopping the wind deflector 103 from rotating and improving the user experience. Furthermore, the distance from the surface of the first anti-rotation block 106 and the second anti-rotation block 105 that is first passed by the wind deflector 103 to the insertion part 112 is relatively large. This allows the fixing hole 102 to extend a relatively small length along the length direction of the first baffle 101. When the wind deflector 103 rotates in the closing direction, the insertion part 112 moves a small distance along the length direction of the fixing hole 102. This allows one long edge of the wind deflector 103 to be locked between the third anti-rotation block 106 and the second anti-rotation block 105, which facilitates user operation and improves user experience.

[0058] In one embodiment of the present invention, the surface of the third anti-rotation block 106 and the second anti-rotation block 105 that is first passed by the wind deflector 103 and faces the insertion portion 112 is an inclined surface, so that the wind deflector 103 slides into the space between the third anti-rotation block 106 and the second anti-rotation block 105 along the inclined surface.

[0059] In this embodiment, the surface of the third anti-rotation block 106 and the second anti-rotation block 105 that is first passed by the wind deflector 103 and faces the insertion portion 112 is inclined towards the surface of the third anti-rotation block 106 and the second anti-rotation block 105 that is subsequently passed by the wind deflector 103. Furthermore, the edge of the inclined surface of the first surface passed by the wind deflector 103 has a larger distance to the insertion portion 112 than the edge of the inclined surface of the second surface passed by the wind deflector 103. Specifically, for example, see... Figure 2 The surface of the third anti-rotation block 106 facing the insertion part 112 is inclined, and the distance from the edge of the first one passed by the wind deflector 103 to the insertion part 112 is larger than the distance from the edge of the second one passed by the wind deflector 103. Since the surface of the first one passed by the wind deflector 103 facing the insertion part 112 of the third anti-rotation block 106 and the second anti-rotation block 105 is inclined, the user can use a small force to make the wind deflector 103 slide between the third anti-rotation block 106 and the second anti-rotation block 105 along the inclined surface, improving the user experience.

[0060] In one embodiment of the present invention, one of the two first baffles 101 has a first recessed region 107 and a second recessed region 108 recessed at both ends of the side without the fixing hole 102 along its length direction, which serve as a handle portion. The edges of the surfaces having the first recessed region 107 and the second recessed region 108 extend outward to form flanges 109.

[0061] In this embodiment, one of the two first baffles 101 has a first recessed area 107 and a second recessed area 108 at both ends of the side without the fixing hole 102 along its length direction, which are recessed towards the side with the fixing hole 102, serving as a handle. This allows the user to operate the fresh air filter bracket 100 more easily through the handle, improving the user experience. The edges of the surfaces with the first recessed area 107 and the second recessed area 108 extend outward to form a flange 109. When the fresh air filter bracket 100 is installed at the plug-in interface 202 of the fan 200, the flange 109 can be engaged with the outside of the plug-in interface 202, preventing the fresh air filter bracket 100 from being fully inserted into the plug-in interface 202, thereby making it easier to disassemble the fresh air filter bracket 100.

[0062] In one embodiment of the present invention, the number of sets of fixing holes 102 can be multiple, and the fixing holes 102 on the first baffle 101 are arranged sequentially along the length direction of the first baffle 101.

[0063] In this embodiment, the number of sets of fixing holes 102 is multiple, for example, 5 sets, meaning there are multiple wind deflector components. This avoids the wind deflector 103 being too wide, thus preventing it from occupying too much space when the area between the two first baffles 101 is fully opened using multiple wind deflectors 103. Generally, the width of the wind deflector 103 can be less than or equal to the width of the first baffle 101.

[0064] In one embodiment of the present invention, the fresh air filter support 100 may further include a second baffle 110 and a third baffle 111. The second baffle 110 and the third baffle 111 are respectively fixed at both ends of the length direction of the two first baffles 101. That is, the second baffle 110, the third baffle 111 and the two first baffles 101 form a quadrilateral.

[0065] In this embodiment, the second baffle 110 and the third baffle 111 can fix the two first baffles 101, prevent the relative position of the two first baffles 101 from changing, and also prevent the plug part 112 from detaching from the fixing hole 102.

[0066] See Figure 7 and Figure 8 Based on the same concept, the present invention also provides a fan 200. The fan 200 may include a fan body 201 and a fresh air filter bracket 100 according to any of the above embodiments. The fan body 201 has a connector 202 at its air inlet. The fresh air filter bracket 100 is detachably inserted into the connector 202.

[0067] In this embodiment, specifically, see [link to relevant documentation]. Figure 8 , Figure 8 The fresh air filter bracket 100 is placed vertically, and the wind deflector 103 is closed to prevent air from passing through the fresh air filter bracket 100.

[0068] The above embodiments can be combined arbitrarily. Based on any one preferred embodiment or a combination of multiple preferred embodiments, the embodiments of the present invention can achieve the following beneficial effects:

[0069] The fresh air filter bracket 100 of the present invention may include two opposing first baffles 101 and at least one wind-blocking component. At least one set of opposing fixing holes 102 are respectively formed on the opposing sides of the two first baffles 101. The wind-blocking component includes a wind-blocking plate 103, with opposing insertion portions 112 formed at both ends along its length. The insertion portions 112 are rotatably inserted into their corresponding fixing holes 102. The wind-blocking plate 103 rotates in the corresponding fixing holes 102 along an opening or closing direction through the insertion portions 112 to open or close the area between the two first baffles 101, thereby allowing or blocking air from passing through the fresh air filter bracket 100 according to actual needs. This structural design is very simple. Furthermore, the wind-blocking component and the first baffles 101 can form an integral structure, preventing the loss of the wind-blocking component.

Claims

1. A fresh air filter holder, comprising: Two opposing first baffles, each having at least one set of opposing fixing holes on its opposing side; At least one windbreak component, the number of which corresponds one-to-one with the number of sets of fixing holes. The windbreak assembly includes: The wind deflector has opposing insertion portions at both ends along its length, and the insertion portions are rotatably inserted into corresponding fixing holes; the wind deflector is configured to rotate in the corresponding fixing holes along an opening or closing direction via the insertion portions to open or close the area between the two first baffles; At least one first anti-rotation block is fixed on one side of the two first baffles facing each other; the first anti-rotation block is configured to abut against the wind deflector when the wind deflector is in the open state, preventing the wind deflector from rotating in a closing direction under the action of gravity; At least one second anti-rotation block is fixed on one side of the two first baffles facing each other and is arranged along the length of the first baffles with respect to the first anti-rotation block; the second anti-rotation block is configured to prevent the wind deflector from rotating in an opening direction when the wind deflector is in the closed state. At least one third anti-rotation block is arranged along the width direction of the first baffle, along with the second anti-rotation block; the fixing hole extends along the length direction of the first baffle so that when the wind deflector rotates in the closing direction, the insertion portion moves along the length direction of the fixing hole, causing one long edge of the wind deflector to be engaged between the third anti-rotation block and the second anti-rotation block; the third anti-rotation block is configured to prevent the wind deflector from rotating in the other opening direction when it is in the closed state; the distances from the faces of the third anti-rotation block and the second anti-rotation block facing the insertion portion to the insertion portion are different. When the wind deflector rotates in the closing direction, the distance from the surface of the third anti-rotation block and the second anti-rotation block that is first passed by the wind deflector to the insertion part is larger. The surface of the third anti-rotation block and the second anti-rotation block that is first passed by the wind deflector and faces the insertion part is an inclined surface, so that the wind deflector slides into the space between the third anti-rotation block and the second anti-rotation block along the inclined surface.

2. The fresh air filter support according to claim 1, wherein, The insertion portion is located near the length edge of its end; The first anti-rotation block is located on one side of the insertion part along the length direction of the first baffle, and when the wind deflector is in the open state, it abuts against the area between the long edge of the wind deflector near the insertion part and the insertion part.

3. The fresh air filter support according to claim 1, wherein, The first anti-rotation block is located on the other side of the insertion part along the length direction of the first baffle, and when the wind deflector is in the open state, it abuts against the area between the length edge of the wind deflector away from the insertion part and the insertion part.
