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] Another objective of this invention is to avoid gaps between adjacent windshields.

[0006] Specifically, the present invention provides a fresh air filter holder, comprising:

[0007] Two opposing first baffles are provided, and each of the two first baffles has a sliding groove extending along its length on its opposite side, and the sliding groove gradually narrows along the length of the first baffle.

[0008] Multiple wind deflectors are arranged sequentially along the length of the first baffle; each wind deflector has an insertion portion formed at both ends along its length, and the cross-sectional dimensions of the insertion portions between adjacent wind deflectors gradually decrease, and are respectively adapted to the partial width of the slide groove;

[0009] Each of the wind deflectors is configured such that its insertion portion is engaged in the width of the slide groove to close the area between the two first baffles, and is also configured such that its insertion portion is engaged at the widest end of the slide groove to open the area between the two first baffles.

[0010] Optionally, the plug portion with the largest cross-sectional dimension is located at the end of the edge of the length of the windshield where it is located, while the other plug portions are located outside the end of the edge of the length of the windshield where they are located.

[0011] Optionally, the chute is divided into multiple sections of different widths along the length of the first baffle, with the width of adjacent sections gradually decreasing.

[0012] Optionally, the fresh air filter holder also includes:

[0013] The second baffle is fixed at both ends along its length to the ends of the two first baffles that are closest to the widest end of the groove along its length.

[0014] Optionally, a third baffle is formed by extending one long edge of the second baffle toward the end of the first baffle away from the widest end of the chute in the length direction; the third baffle overlaps with the chute in the length direction of the first baffle, and the width of the third baffle in the length direction of the first baffle is greater than or equal to the thickness of each of the wind deflectors after overlap.

[0015] The end of the third baffle extends toward the other length edge of the second baffle until it extends to the length edge of the groove to form a fourth baffle.

[0016] Optionally, the groove is located near the length edge of the first baffle;

[0017] The second baffle extends along one length edge of the groove to form the third baffle.

[0018] Optionally, the fresh air filter bracket further includes: a fifth baffle, the two ends of which are respectively fixed to the ends of the two first baffles that are furthest from the widest end of the slide groove in the length direction;

[0019] The middle of the length edge of the fourth baffle extends to the middle of the length edge of the fifth baffle to form a limiting plate;

[0020] The middle portion of the limiting plate extends to both sides of the first baffle to form a reinforcing plate.

[0021] Optionally, the cross-section of the largest of the plug-in portions is circular;

[0022] At least one of the length edges at the widest end of the groove is an arc-shaped edge, so that the largest insertion portion is rotatably located in the widest end.

[0023] 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 groove in the length direction, which are recessed toward the side with the groove to serve as a handle.

[0024] The edges of the surfaces having the first recessed region and the second recessed region extend outward to form a flange.

[0025] According to another aspect of the present invention, a fan is also provided, 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 includes two opposing first baffles and multiple wind deflectors. Each of the two opposing first baffles has a groove extending along its length, and the groove gradually narrows along the length of the first baffle. The multiple wind deflectors are arranged sequentially along the length of the first baffles; each wind deflector has an insertion portion formed at both ends along its length, and the cross-sectional dimensions of the insertion portions of each wind deflector gradually narrow along the length of the first baffle, respectively adapting to a portion of the width of the groove. Each wind deflector can either lock its insertion portion within the width of the groove to close the area between the two first baffles, thereby blocking air passage, or lock its insertion portion at the widest end of the groove to open the area between the two first baffles, allowing air passage. This allows for flexible blocking or allowing of air passage according to actual needs. The structural features of the present invention fully utilize the effect of gravity, and the design is very novel and ingenious.

[0029] Furthermore, the largest cross-sectional area of ​​the insertion part is located at the end of the length edge of its respective wind deflector, while the remaining insertion parts are located outside the ends of the length edges of their respective wind deflector. Having the largest cross-sectional area at the end of the length edge of its respective wind deflector ensures that, when the widest end of the groove faces downwards, the largest cross-sectional area is positioned at the widest point of the groove, allowing it to rotate freely within the groove and move out of its vertical position. This provides space for other wind deflectors to slide down, making it easier for each wind deflector to slide to the widest end of the groove. Furthermore, having the remaining insertion parts located outside the ends of the length edges of their respective wind deflector allows the length edges of adjacent wind deflectors to more easily abut completely when the widest end of the groove faces upwards, eliminating gaps between adjacent wind deflectors and preventing air passage. If all the insertion parts of each wind deflector were located at the ends of their respective length edges, it would be difficult to ensure complete abutment between adjacent insertion parts due to their different dimensions.

[0030] Furthermore, when the widest end of the chute faces upward to block air from passing through, each baffle is in a downward-extended state. However, there may be a gap between the baffle closest to the second baffle and the second baffle. This can cause some air to pass through the gap and through the fresh air filter support. To prevent air from passing through the gap and through the fresh air filter support, one long edge of the second baffle extends towards the end away from the widest end of the chute in the length direction of the first baffle to form a third baffle. The third baffle overlaps with the chute in the length direction of the first baffle, and thus overlaps with the baffle in the length direction of the first baffle, preventing air from passing through the gap and through the fresh air filter support.

[0031] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0041] 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.

[0042] Figure 1 This is a schematic structural diagram of a fresh air filter holder according to an embodiment of the present invention. See also... Figure 1The fresh air filter bracket 100 generally includes two opposing first baffles 101 and a plurality of baffles 103. Each of the two first baffles 101 has a groove 102 extending along its length on its opposing side, and the groove 102 gradually tapers along the length of the first baffle 101. The plurality of baffles 103 are arranged sequentially along the length of the first baffles 101; each baffle 103 has an insertion portion 104 formed at both ends along its length, and the cross-sectional dimension of the insertion portion 104 of each baffle 103 gradually tapers along the length of the first baffle 101, and is adapted to a portion of the width of the groove 102. Each baffle 103 can have its insertion portion 104 engaged within the width of the groove 102 to close the area between the two first baffles 101, and can also have its insertion portion 104 engaged at the widest end of the groove 102 to open the area between the two first baffles 101.

[0043] In this embodiment, the fresh air filter bracket 100 is used to install and support the filter for air filtration. The size of the cross-section of the connector 104 can represent the thickness of the connector 104. When the connector 104 is cylindrical, the size of the cross-section of the connector 104 can refer to the diameter of the cross-section. When the cross-section of the connector 104 is not a circle, the size of the cross-section can refer to the length of the longest diagonal in the cross-section. Multiple wind deflectors 103 are arranged sequentially along the length of the first baffle 101. Each wind deflector 103 has an insertion portion 104 formed at both ends along its length. The cross-sectional dimension of the insertion portion 104 of each wind deflector 103 gradually decreases along the length of the first baffle 101 and is adapted to a portion of the width of the slide groove 102. Each wind deflector 103 can either lock its insertion portion 104 within the width of the slide groove 102 to close the area between the two first baffles 101, thus blocking air passage, or lock its insertion portion 104 at the widest end of the slide groove 102 to open the area between the two first baffles 101, allowing air passage. This allows for flexible blocking or allowing of air passage through the fresh air filter support 100 according to actual needs. Specifically, for example, if it is necessary to block air passage through the fresh air filter support 100, the widest end of the slide groove 102 can be oriented upwards, as shown below. Figure 1 As shown, each wind deflector 103 is engaged with its corresponding position in the slide groove 102 via the insertion part 104, and unfolds downwards under the action of gravity, thereby closing the area between the two first baffles 101; if it is necessary to allow air to pass through the fresh air filter bracket 100, the widest end of the slide groove 102 can be oriented downwards, as shown in the figure. Figure 2As shown, each wind deflector 103 slides downward under the action of gravity until the insertion portion 104 of each wind deflector 103 slides to the end of the groove 102, thereby opening the area between the two first baffles 101. The structural features of this invention make full use of the effect of gravity, and the design is very novel and ingenious. Furthermore, the wind deflector 103 and the first baffle 101 are connected as a whole, preventing the wind deflector 103 from being lost.

[0044] See Figure 3 , Figure 3 This is a schematic structural diagram of a windshield according to another embodiment of the present invention. In one embodiment of the present invention, the insertion portion 104 with the largest cross-sectional dimension is located at the end of the length edge of the windshield 103, and the other insertion portions 104 are located outside the ends of the length edges of the windshield 103.

[0045] In this embodiment, the insertion part 104 with the largest cross-sectional size is located at the end of the length edge of the windshield 103. When the widest end of the slide groove 102 faces downwards, it can be ensured that the insertion part 104 with the largest cross-sectional size is at the widest position of the slide groove 102. Figure 2 As shown, the insertion portion 104 with the largest cross-sectional dimension can rotate flexibly within the slide groove 102 to move out of its vertical position, providing space for other wind deflectors 103 to slide down, thus making it easier for each wind deflector 103 to slide to the widest end of the slide groove 102. Furthermore, the remaining insertion portions 104 are located outside the ends of the length edges of their respective wind deflectors 103. When the widest end of the slide groove 102 is facing upwards, the length edges of adjacent wind deflectors 103 can more easily abut together completely, thereby eliminating gaps between adjacent wind deflectors 103 and preventing air from passing through. If the insertion portions 104 of each wind deflector 103 were all located at the ends of the length edges of their respective wind deflectors 103, when adjacent insertion portions 104 abut together, due to the different dimensions of the adjacent insertion portions 104, it would be difficult to ensure that the length edges of adjacent wind deflectors 103 completely abut together, resulting in gaps between adjacent wind deflectors 103.

[0046] In one embodiment of the present invention, the slide 102 is divided into multiple sections of different widths along the length direction of the first baffle 101, and the width of adjacent sections gradually decreases.

[0047] In this embodiment, the width of the same section of the slide 102 can be the same. Dividing the slide 102 along the length of the first baffle 101 into multiple sections of different widths allows for easier and more accurate determination of the position where the wind deflector 103 needs to be positioned, based on the width of the wind deflector 103 and the size of its insertion portion 104. This minimizes or eliminates the gap between adjacent wind deflectors 103 when it is necessary to block airflow through the fresh air filter bracket 100. Specifically, for example, if there are five wind deflectors 103, and the diameter of the cross-section of the insertion portion 104 of each wind deflector 103 is 3 mm, 2.5 mm, 2 mm, 1.5 mm, and 1 mm respectively, the slide 102 can be divided into four sections of different widths, each with a width of 3 mm, 2.5 mm, 2 mm, and 1.5 mm respectively. The insertion portion 104 of each wind deflector 103 is engaged at the end of the slide 102 and its corresponding section. For example, a 3 mm insertion portion 104... 04 is engaged at the end of the 3 mm section of the slide groove 102, 2.5 mm insertion part 104 is engaged at the adjacent ends of the 3 mm and 2.5 mm sections of the slide groove 102, 2 mm insertion part 104 is engaged at the adjacent ends of the 2.5 mm and 2 mm sections of the slide groove 102, 1.5 mm insertion part 104 is engaged at the adjacent ends of the 2 mm and 1.5 mm sections of the slide groove 102, and 1 mm insertion part 104 is engaged at the other end of the 1.5 mm section of the slide groove 102.

[0048] In one embodiment of the present invention, the fresh air filter support 100 may further include a second baffle 105. The two ends of the second baffle 105 in the length direction are respectively fixed to the ends of the two first baffles 101 near the widest ends of the slide groove 102 in the length direction.

[0049] In this embodiment, when the widest end of the slide groove 102 faces downwards, each wind deflector 103 slides down to the widest end of the slide groove 102. If each wind deflector 103 is still in a downward-facing unfolded state, it will occupy a lot of space. To avoid the problem of excessive space occupation by the wind deflectors 103, the wind deflectors 103 can overlap and be placed on the second baffle 105, reducing space occupation and making the overall structure of the fresh air filter support 100 more compact. The effect of the wind deflectors 103 overlapping and being placed on the second baffle 105 is as follows: Figure 2 As shown.

[0050] See Figure 4 In one embodiment of the present invention, a length edge of the second baffle 105 extends toward the end of the first baffle 101 away from the widest end of the slide groove 102 to form a third baffle 106; the third baffle 106 overlaps with the slide groove 102 in the length direction of the first baffle 101, and the width of the third baffle 106 in the length direction of the first baffle 101 is greater than or equal to the thickness of each wind deflector 103 after overlap;

[0051] The end of the third baffle 106 extends toward the other length edge of the second baffle 105 until it extends to the length edge of the groove 102 to form the fourth baffle 107.

[0052] In this embodiment, when the widest end of the groove 102 faces upward to block air passage, each wind deflector 103 is in a downward-extended state. However, the wind deflector 103 closest to the second baffle 105 may have a gap with the second baffle 105. Figure 5 As shown, this causes some air to pass through the gap into the fresh air filter support 100. To prevent air from passing through the gap into the fresh air filter support 100, a third baffle 106 is formed by extending one long edge of the second baffle 105 toward the end of the first baffle 101 away from the widest end of the slide 102 in the length direction. The third baffle 106 overlaps with the slide 102 in the length direction of the first baffle 101, and further overlaps with the wind deflector 103 in the length direction of the first baffle 101, thus preventing air from passing through the gap into the fresh air filter support 100. In addition, the fourth baffle 107 is adjacent to the long edge of the slide 102. When the widest end of the slide 102 is facing upward to block air passage, the fourth baffle 107 can abut against the wind deflector 103 that is stuck at the widest end of the slide 102, so as to prevent the wind deflector 103 that is stuck at the widest end of the slide 102 from creating gaps when the airflow is large, thereby further preventing air from passing through the fresh air filter support 100. Furthermore, the width of the third baffle 106 in the length direction of the first baffle 101 is greater than or equal to the thickness of the overlapping wind deflectors 103, that is, the width of the third baffle 106 in the length direction of the first baffle 101 is greater than or equal to the thickness of the overlapping joints 104 of the wind deflectors 103, such as... Figure 2 As shown, when the widest end of the slide 102 is facing down to allow air to pass through, the folded wind deflectors 103 can be positioned between the fourth baffle 107 and the second baffle 105, making the overall structure of the fresh air filter support 100 more compact.

[0053] In one embodiment of the present invention, the slide 102 is located near the length edge of the first baffle 101;

[0054] The second baffle 105 extends along one long edge of the slide groove 102 to form the third baffle 106.

[0055] In this embodiment, the slide 102 is located near the length edge of the first baffle 101. When the widest end of the slide 102 is facing down to allow air to pass through, it can prevent the overlapping wind deflectors 103 from being located outside the width direction of the first baffle 101, thus reducing the space occupied.

[0056] In one embodiment of the present invention, the fresh air filter support 100 may further include:

[0057] The fifth baffle 108 has its two ends fixed in the length direction to the ends of the two first baffles 101 that are furthest from the widest ends of the slide groove 102 in the length direction.

[0058] The middle of the length edge of the fourth baffle 107 extends to the middle of the length edge of the fifth baffle 108 to form a limiting plate 109;

[0059] The middle part of the limiting plate 109 extends to both sides of the first baffle 101 to form a reinforcing plate 110.

[0060] In this embodiment, when the widest end of the slide groove 102 faces downwards to allow air passage, the limiting plate 109 helps the baffles 103 overlap and rest on the second baffle 105 as they slide towards the widest end of the slide groove 102. Furthermore, when the widest end of the slide groove 102 faces upwards to block air passage, the limiting plate 109 abuts against each unfolded baffle 103, preventing the baffles 103 from moving with the airflow when the airflow is too strong, thus preventing gaps between the baffles 103 and preventing air passage. The reinforcing plate 110 increases the strength of the limiting plate 109, thereby preventing deformation when the airflow is strong.

[0061] In one embodiment of the present invention, the cross-section of the largest of the plug-in portions 104 is circular;

[0062] At least one of the length edges at the widest end of the groove 102 is an arc-shaped edge, so that the largest insertion portion 104 is rotatably located in the widest end.

[0063] In this embodiment, if it is necessary to allow air to pass through the fresh air filter bracket 100, the widest end of the slide groove 102 can be oriented downwards. To ensure that each baffle 103 can slide towards the widest end of the slide groove 102, the baffle 103 with the largest insertion portion 104 needs to rotate under the influence of gravity towards the area between the first baffles 101, i.e., no longer maintain a vertical state, so as to provide space for the other baffles 103 to slide down. At least one of the long edges at the widest end of the slide groove 102 is an arc-shaped edge, so that the largest insertion portion 104 is rotatably located in the widest end, so that the baffle 103 can rotate more easily towards the area between the first baffles 101. Of course, the widest end of the slide groove 102 can also be a similar circular structure, which also allows the insertion portion 104 therein to rotate flexibly. In addition, the cross-sectional shape of each insertion portion 104 can preferably be circular.

[0064] In one embodiment of the present invention, one of the two first baffles 101 has a first recessed region 111 and a second recessed region 112 recessed at both ends of the side without the groove 102 along its length direction, which serve as a handle portion. The edges of the surfaces having the first recessed region 111 and the second recessed region 112 extend outward to form a flange 113.

[0065] In this embodiment, the first recessed area 111 and the second recessed area 112 serve as handles, making it easier for users to use the fresh air filter bracket 100. Additionally, the air inlet of the fan body has a connector that fits the fresh air filter bracket 100. The fresh air filter bracket 100 is detachably inserted into the connector, with the flange 113 engaging on the outside of the connector, allowing users to more easily remove the fresh air filter bracket 100.

[0066] In some other embodiments of the present invention, the groove 102 may penetrate through the first baffle 101 in which it is located.

[0067] In this embodiment, the chute 102 extends through the first baffle 101, allowing the user to see from multiple angles which end of the chute 102 is the widest and which end is the narrowest. This makes it easier for the user to decide which end of the chute 102 should face up or down to allow or block air from passing through the fresh air filter bracket 100.

[0068] See Figures 6 to 8 Based on the same concept, the present invention also provides a fan 200. The fan 200 includes 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.

[0069] Specifically, when it is necessary to block air passage, the widest end of the slide 102 should be facing upwards, and the fresh air filter bracket 100 should be inserted into the connector 202. Figure 6 and Figure 8 The state shown is as follows. When air is allowed to pass through, the widest end of the slide 102 is facing down, and the fresh air filter bracket 100 is inserted into the insertion interface 202, as shown. Figure 7 The state shown in the image.

[0070] 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:

[0071] The fresh air filter support 100 of the present invention includes two opposing first baffles 101 and a plurality of wind deflectors 103. Each of the two opposing first baffles 101 has a groove 102 extending along its length direction on its opposite side, and the groove 102 gradually tapers along the length direction of the first baffle 101. The plurality of wind deflectors 103 are arranged sequentially along the length direction of the first baffles 101; each wind deflector 103 has an insertion portion 104 formed at both ends along its length direction, and the cross-sectional dimension of the insertion portion 104 of each wind deflector 103 gradually tapers along the length direction of the first baffle 101, and is adapted to a portion of the width of the groove 102. In this invention, each wind deflector 103 has its insertion portion 104 engaged within the width of the sliding groove 102 to close the area between the two first baffles 101, thereby blocking air passage. Alternatively, its insertion portion 104 can be engaged at the widest end of the sliding groove 102 to open the area between the two first baffles 101, allowing air passage. This allows for flexible blocking or allowing of air passage through the fresh air filter bracket 100 according to actual needs. The structural features of this invention fully utilize the effect of gravity, resulting in a novel and ingenious design.
