[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] See also Figures 1 to 7 The utility model proposes a noise reduction air guide ring 100, including a first air guide member 110 and a second air guide member 120; the first air guide member 110 has an air guide channel 110a, and the air guide channel 110a has an air inlet 110a1 and an air outlet 110a2; the second air guide member 120 is arranged in the air guide channel 110a, and the second air guide member 120 includes a mounting portion 122 and an air guide portion 124, the mounting portion 122 is located at one end of the second air guide member 120 close to the air outlet 110a2, and is used for being installed on an external structure, and the air guide portion 124 is located at one end of the second air guide member 120 close to the air inlet 110a1, and is used for guiding air.

[0039] It should be noted that the noise reduction air guide ring 100 proposed in this embodiment can be applied to scenarios where there are draft problems in some air guide channels 110a.

[0040] When the noise reduction air guide ring 100 of this embodiment is used, the mounting portion 122 is disposed at an external structure where a draft problem exists. Since the air guide portion 124 and the mounting portion 122 are disposed along the wind guiding direction of the wind guiding passage 110a, the air guide portion 124 is disposed in front of the external structure in the wind guiding direction. When air enters the wind guiding passage 110a, it can flow along the side wall of the external structure under the guidance of the air guide portion 124.

[0041] By adopting the technical solution of this embodiment, the first air guide member 110 can serve as the main body of the air guide, and the airflow blocked by the external structure is guided by the second air guide member 120, thereby improving the air guiding effect of the external structure using the noise reduction air guide ring 100 and reducing the overall noise.

[0042] In addition, the air guiding portion 124 and the mounting portion 122 in the second air guiding member 120 are two virtual terms introduced to facilitate the description of the function of the second air guiding member 120 , and in the actual structure, there may be no obvious structural lines to distinguish them.

[0043] See also Figures 4 to 7 As shown in any of the accompanying drawings, in some embodiments, a limiting surface 124d is provided at one end of the air guide portion 124 close to the mounting portion 122, and the limiting surface 124d is used to abut against an external structure.

[0044] The second air guide 120 proposed in this embodiment can be used for some external structures of a slot body structure, the mounting portion 122 is embedded in the slot body, and the limiting surface 124d abutting against the structure can cover the slot body. Such a design can prevent the airflow in the air guide channel 110a from flowing into the slot body at both sides of the second air guide 120, thereby relatively improving the efficiency of air guide.

[0045] In addition, the limiting surface 124d can be a plane, or a curved surface, an arc surface, a wavy surface, etc., which is not limited in this embodiment, and it only needs to protrude from the surface of the mounting portion 122 and cover the groove body.

[0046] Of course, in other embodiments, the external structure applicable to the second air guide 120 may also be some protruding solid structure, and the mounting portion 122 is attached to the external structure. The second air guide 120 may not be provided with a limiting surface 124d, and the mounting portion 122 is connected to the air guide 124 through a smooth curved surface or a straight surface. In order to avoid the phenomenon of wind circling, the end surface of the mounting portion 122 close to the external structure is larger than the end surface of the external structure close to the second air guide 120.

[0047] In some embodiments, a first wind guide surface 124a and a second wind guide surface 124b are provided at one end of the wind guide portion 124 away from the mounting portion 122, and the first wind guide surface 124a and the second wind guide surface 124b are inclined to each other; or, an arc-shaped third wind guide surface 124c is provided at one end of the wind guide portion 124 away from the mounting portion 122.

[0048] See also Figures 4 to 7 , respectively showing the shapes of the projections of the second air guide 120 on a plane perpendicular to its length direction in different embodiments.

[0049] like Figure 4 As shown, the end of the air guide portion 124 away from the mounting portion 122 is provided with a first air guide surface 124a and a second air guide surface 124b, the first air guide surface 124a and the second air guide surface 124b form an isosceles triangle structure, and the first air guide surface 124a and the second air guide surface 124b are smoothly connected by an arc surface. The air guide portion 124 provided in this embodiment can be applied to the middle part of the air guide channel 110a to achieve a uniform air outlet effect.

[0050] like Figure 5 As shown, an end of the air guide portion 124 away from the mounting portion 122 is provided with an air guide surface and a second air guide surface 124b, the first air guide surface 124a and the second air guide surface 124b form an unequal triangle structure, and the first air guide surface 124a and the second air guide surface 124b are smoothly connected by an arc surface. The inclination angle of the first air guide surface 124a and the second air guide surface 124b can be designed based on the position of the second air guide member 120 so that the airflow guided by the air guide portion 124 can be closer to the middle of the air guide channel 110a.

[0051] like Figure 6 As shown, the wind guide portion 124 is provided with a third wind guide surface 124c at one end away from the mounting portion 122, and the projection of the third wind guide surface 124c on a plane perpendicular to the length direction is an arc. The design scheme of this embodiment is relatively convenient for product design.

[0052] like Figure 7 As shown, the wind guide portion 124 is provided with a third wind guide surface 124c at one end of the wind guide portion 124 away from the mounting portion 122, and the projection of the third wind guide surface 124c on a plane perpendicular to the length direction is two tangent parabolas. The shape of the parabola can be designed according to the maximum airflow, and the larger the maximum airflow value, the longer the length of the wind guide portion 124 in the direction close to or away from the mounting portion 122 can be relatively increased.

[0053] See also Figures 1 to 3 In some embodiments, there are multiple second air guide members 120, and the multiple second air guide members 120 are arranged around the center of the air guide channel 110a.

[0054] In this embodiment, the plurality of second air guide members 120 may be connected to each other or may be connected via other structures.

[0055] By adopting the technical solution of this embodiment, on the one hand, the problem of multiple wind scoops can be solved by using multiple second air guides 120; on the other hand, the second air guides 120 can be equivalent to reinforcing ribs to improve the overall structural strength of the noise reduction air guide ring 100.

[0056] Optionally, the number of the second air guide members 120 is four, and the angle between two adjacent second air guide members 120 is 90°.

[0057] Please continue reading Figures 1 to 3 In some embodiments, the noise reduction air guide ring 100 further includes a connecting member 130 , which is hollow and has a plurality of second air guide members 120 fixed thereon.

[0058] Specifically, the connector 130 includes a plurality of sequentially connected connectors 132, each connector 132 connecting two adjacent second air guides 120, and a plurality of connectors 132 connected end to end to form a ring. It is worth mentioning that the hollow design of the connector 130 can provide a certain space for the installation of the fan 300, and can also achieve the technical effect of weight reduction.

[0059] Furthermore, the connecting portion 132 includes a first connecting segment 1322, a second connecting segment 1324 and a third connecting segment 1326 which are connected in sequence, the first connecting segment 1322 and the third connecting segment 1326 respectively connect two adjacent second air guides 120, and the second connecting segment 1324 is a curved segment. Compared with the connecting portion 132 which is a straight segment as a whole, the structural strength of the connecting portion 132 in this embodiment is higher.

[0060] In order to reduce the mass of the second air guide 120, a weight reduction groove is provided at one end of the mounting portion 122 away from the air guide portion 124, and the weight reduction groove extends along the length direction of the second air guide 120. It is worth mentioning that the structure at the weight reduction groove is equivalent to forming a reinforcing rib structure, which improves the strength of the second air guide 120.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments, the first air guide member 110 includes a surrounding portion 112 having an air guide channel 110 a , and the second air guide member 120 is fixedly disposed on the surrounding portion 112 .

[0062] In this embodiment, the surrounding portion 112 is a ring structure with a constant wall thickness, and the second air guide 120 internally supports the surrounding portion 112. With such a design, the first air guide 110 can have a relatively light mass and can also have a certain structural strength.

[0063] Furthermore, the first air guide 110 further includes a clamping portion 116, which is disposed on the outer wall of the surrounding portion 112, and the clamping portion 116 can be used to clamp with an external structure.

[0064] Optionally, there are multiple clamping portions 116 .

[0065] Optionally, the number of the clamping portions 116 is four.

[0066] like Figure 2 As shown, in some embodiments, one end of the surrounding portion 112 away from the air outlet 110a2 is provided with a flange 114, and the diameter of the flange 114 gradually decreases from the air inlet 110a1 to the air outlet 110a2.

[0067] In this embodiment, the flange 114 can be a slope, a curved surface, or a combination of a slope and a curved surface.

[0068] The structural design of the flange 114 in this embodiment can not only increase the length of the air guide channel 110a, thereby increasing the maximum air supply distance of the airflow, but also increase the diameter of the air inlet 110a1 and increase the air intake volume.

[0069] In some embodiments, the first air guide member 110 and / or the second air guide member 120 is a plastic member.

[0070] In a feasible implementation, the first air guide 110 and the second air guide 120 are integrally formed by injection molding. Of course, in other implementations, the first air guide 110 and the second air guide 120 are independently injection molded and then assembled and fixed.
