Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a duct connector and an exhaust assembly. Background Technology

[0002] Traditional portable air conditioner duct connectors are typically installed in two ways to the window panel. One method involves directly pressing and fixing the connector with elastic clips. This method is convenient to install but difficult to disassemble. It requires force to pull out the duct connector or to open the window and remove the window panel before manually pressing the clips on the duct connector from the other side to release them. The other method involves separating the duct connector's connecting clip into a separate part or a small component. This method is easier to install and disassemble than the first one, but it is more expensive due to the increased number of parts. Utility Model Content

[0003] Therefore, it is necessary to provide a duct connector and exhaust assembly to address the above-mentioned problems.

[0004] The first aspect of this application provides a duct connector for use with a mounting plate, wherein the mounting plate has assembly holes. The duct connector includes a connector body and a first connecting part, a second connecting part and a third connecting part disposed on the connector body, wherein the third connecting part is used to connect to an exhaust duct.

[0005] The first connecting part is an elastic structure, and the second connecting part is a rigid structure. The first connecting part and the second connecting part respectively cooperate with the connector body to form a first fastening structure and a second fastening structure.

[0006] The connector body at least partially penetrates the assembly hole, and the first fastening structure and the second fastening structure are respectively fastened to the mounting plate.

[0007] This application discloses a duct connector, the connector body of which is provided with a first connecting part, a second connecting part, and a third connecting part. The first connecting part and the second connecting part, together with the connector body, form a first fastening structure and a second fastening structure, respectively. During the assembly process of the connector body and the mounting plate, based on the fact that the second connecting part is a rigid structure, the second fastening structure is first fastened to the mounting plate, achieving initial positioning of the connector body on the mounting plate. Because the first connecting part is an elastic structure, when the first fastening structure is assembled with the mounting plate, the first connecting part undergoes elastic deformation, and the first fastening structure fastens to the mounting plate, thereby achieving assembly of the connector body and the mounting plate. Simultaneously, when it is necessary to remove the duct connector from the mounting plate, the first connecting part undergoes elastic deformation first, causing the first fastening structure to disengage from the mounting plate, and then the second connecting part disengages from the mounting plate. Based on the cooperation of the first connecting part, the second connecting part, and the connector body, this application facilitates the assembly and disassembly of the duct connector on the mounting plate, while also providing a sufficiently large disengagement force.

[0008] In one embodiment, the connector body includes an inner shroud and an outer shroud connected to the inner shroud. The diameter of the inner shroud is smaller than the diameter of the mounting hole, and the diameter of the outer shroud is larger than the diameter of the mounting hole. A height difference H1 is formed between the inner shroud and the outer shroud.

[0009] In the above embodiment of the duct connector, the diameter of the inner shroud is smaller than the diameter of the assembly hole, allowing the inner shroud to pass through the assembly hole. A height difference H is formed between the inner shroud and the outer shroud, and the diameter of the outer shroud is larger than the diameter of the assembly hole, so that after the inner shroud passes through the assembly hole, the outer shroud rests against the mounting plate, preventing the mounting plate from moving further relative to the connector body.

[0010] In one embodiment, the second connecting part has a block-shaped structure, the second connecting part is distributed along the outer edge of the inner circumference plate, and the sum of the width of the second connecting part and the diameter of the inner circumference plate is greater than the diameter of the assembly hole, and the snap-fit ​​space between the second connecting part and the outer circumference plate forms the second fastening structure.

[0011] In the above embodiment, the duct connector is located on the outer edge of the inner panel via a second connecting portion. The second connecting portion is a block structure, which creates a snap-fit ​​space between the second connecting portion and the outer panel. During the assembly of the duct connector and the mounting plate, the second connecting portion extends through the assembly hole to the inner side of the mounting plate. Since the sum of the width of the second connecting portion and the diameter of the inner panel is greater than the diameter of the assembly hole, the snap-fit ​​space formed between the second connecting portion and the outer panel can snap-fit ​​and engage with the mounting plate.

[0012] In one embodiment, the second connecting portion is provided with a plurality of spaced first reinforcing ribs, which are respectively connected to the second connecting portion and the inner circumference plate. The height difference H2 between the first reinforcing ribs and the outer circumference plate is less than the height difference H1 between the inner circumference plate and the outer circumference plate.

[0013] In the above embodiment, the duct joint is provided with a first reinforcing rib connected to the second connecting part and the inner circumference plate respectively, which can improve the hardness of the second connecting part and make it less prone to bending or breakage. In addition, since the height difference H2 between the first reinforcing rib and the outer circumference plate is smaller than the height difference H1 between the inner circumference plate and the outer circumference plate, the mounting plate can be clamped between the first reinforcing rib and the outer circumference plate, reducing the shaking of the mounting plate on the second fastening structure.

[0014] In one embodiment, the second connecting part is arc-shaped, and the arc length L1 of the second connecting part satisfies: 0.3L2≤L1≤0.6L2, where L2 is the perimeter of the inner circumference plate.

[0015] In one embodiment, a first clearance opening is provided on the top of the outer perimeter plate, and the height difference H3 between the first clearance opening and the second connecting part is greater than the height difference H1 between the inner perimeter plate and the outer perimeter plate.

[0016] In the above embodiments, the duct connector has a first clearance opening on the top of the outer plate, which facilitates the user's hand to insert into the first clearance opening to control the assembly and disassembly of the connector body and the mounting plate.

[0017] In one embodiment, the first connecting portion includes a first connecting segment, a second connecting segment, and a third connecting segment. The first connecting segment is connected to the inner circumference plate or the outer circumference plate. The second connecting segment is bent relative to the first connecting segment. The third connecting segment is bent relative to the second connecting segment. The second connecting segment is provided with a snap-fit ​​portion. The snap-fit ​​space between the snap-fit ​​portion and the outer circumference plate forms the first fastening structure. The third connecting segment is used to press the second connecting segment to drive the snap-fit ​​portion to move toward the central axis of the assembly hole.

[0018] The duct connector in the above embodiment is connected by bending a first connecting segment, a second connecting segment, and a third connecting segment in sequence. Specifically, the second connecting segment is bent relative to the first connecting segment, and the third connecting segment is bent relative to the second connecting segment. When the third connecting segment is pressed, the second connecting segment is equivalent to the position of the first connecting segment and forms at least a first position and a second position. The second connecting segment is provided with a snap-fit ​​part, and a snap-fit ​​space is formed between the second connecting part and the third connecting part. When the second connecting segment is in the first position, the first fastening structure is in a fastened state with the mounting plate. When the second connecting segment moves from the first position to the second position, the first fastening structure is in a disengaged state with the mounting plate.

[0019] In one embodiment, a second reinforcing rib is provided at the connection between the second connecting segment and the third connecting segment, and the distance between the second reinforcing rib and the snap-fit ​​portion is less than the thickness of the mounting plate.

[0020] In the above embodiment, the duct connector enhances the connection strength between the second and third connecting sections by providing a second reinforcing rib between them, preventing the third connecting section from deforming relative to the second connecting section when it is pressed, thus preventing the second connecting section from deforming properly and causing the snap-fit ​​part to fail. In addition, by providing a second reinforcing rib in the third connecting part, the shaking of the mounting plate on the first fastening structure can be reduced.

[0021] In one embodiment, the duct connector further includes a ventilation grille connected to the cavity of the duct connector.

[0022] The duct connector in the above embodiments, by setting a ventilation grille in the cavity of the duct connector, can effectively prevent external dust, leaves, debris and small animals from entering the duct and avoid blockage; in addition, the ventilation grille can disperse airflow, reduce turbulence, reduce noise generated during exhaust, and improve user comfort.

[0023] The first aspect of this application provides an exhaust assembly, including a mounting plate, an exhaust duct, and a duct connector as described in any one of the above. The mounting plate has an assembly hole, and the duct connector at least partially passes through the assembly hole and is fastened to the mounting plate. One end of the exhaust duct is threadedly connected to the third connecting part, and the other end is connected to the exhaust port of a portable air conditioner.

[0024] The exhaust assembly of this application has an exhaust pipe connected to the exhaust port of the portable air conditioner and a third connecting part. The mounting plate can be used as a window panel, thereby fixing the exhaust pipe to the window. When the portable air conditioner is working, the exhaust gas generated is discharged to the outside through the exhaust pipe and the duct joint in sequence. Attached Figure Description

[0037] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0039] Some embodiments of the duct connectors of the present invention are described below with reference to the accompanying drawings.

[0040] like Figures 1 to 6 As shown, this embodiment discloses a duct connector, which is used in conjunction with a mounting plate 200. The mounting plate 200 has an assembly hole 201. The duct connector 100 includes a connector body 11, and a first connecting part 12, a second connecting part 13 and a third connecting part 14 disposed on the connector body 11. The third connecting part 14 is used to connect with an exhaust duct 300.

[0041] The first connecting part 12 is an elastic structure, and the second connecting part 13 is a rigid structure. The first connecting part 12 and the second connecting part 13 respectively cooperate with the connector body 11 to form a first fastening structure and a second fastening structure.

[0042] The connector body 11 at least partially penetrates the assembly hole 201, and the first fastening structure and the second fastening structure are fastened to the mounting plate 200 respectively.

[0043] The duct connector of this application has a first connecting part 12, a second connecting part 13, and a third connecting part 14 respectively provided on the connector body 11. The first connecting part 12 and the second connecting part 13 form a first fastening structure and a second fastening structure with the connector body 11, respectively. During the assembly process of the connector body 11 and the mounting plate 200, based on the fact that the second connecting part 13 is a rigid structure, the second fastening structure is first fastened to the mounting plate 200 to achieve the initial positioning of the connector body 11 on the mounting plate 200. Because the first connecting part 12 is an elastic structure, when the first fastening structure is assembled with the mounting plate 200, the first connecting part 12 undergoes elastic deformation, and the first fastening structure is fastened to the mounting plate 200, thereby realizing the assembly of the connector body 11 and the mounting plate 200. At the same time, when it is necessary to remove the duct connector 100 from the mounting plate 200, the first connecting part 12 is first elastically deformed to disengage the first fastening structure from the mounting plate 200, and then the second connecting part 13 is disengaged from the mounting plate 200. Based on the cooperation of the first connecting part 12, the second connecting part 13 and the connector body 11, the duct connector 100 can be easily installed and removed on the mounting plate 200, while also having a sufficiently large release force.

[0044] The mounting plate 200 can be a window panel installed on a window or a casing installed on a portable air conditioner. The mounting plate 200 may have a mounting hole 201, the shape of which is adapted to the shape of the duct connector 100; for example, the mounting hole 201 may be circular. During the assembly process between the mounting plate 200 and the duct connector 100, the connector body 11 passes through the mounting hole 201, and the second and first fastening structures are successively fastened to the mounting plate 200, thus fixing the duct connector 100 to the mounting plate 200.

[0045] The connector body 11 can be used to fix the exhaust pipe 300 relative to the mounting plate 200. The connector body 11 can be a hollow cylindrical shell. The connector body 11 can form a first fastening structure with the first connecting part 12, and the connector body 11 can also form a second fastening structure with the second connecting part 13. Since the first connecting part 12 is an elastic structure, by driving the first connecting part 12 to undergo elastic deformation, the fastening or disengagement of the first fastening structure with the mounting plate 200 can be changed. Therefore, when assembling the connector body 11 and the mounting plate 200, the second fastening structure must first be fastened with the mounting plate 200, and then the first fastening structure must be fastened with the mounting plate 200 by causing the first connecting part 12 to undergo elastic deformation. During disassembly, the first connecting part 12 must first undergo elastic deformation to disengage the first fastening structure from the mounting plate 200, and then the second connecting part 13 must be disengaged from the mounting plate 200.

[0046] The third connecting part 14 can be used to connect with the exhaust pipe 300. The third connecting part 14 can be connected to the exhaust pipe 300 by means of snap-fit, thread, etc. In one example, the mounting plate 200 is a window panel installed in the window, one end of the exhaust pipe 300 is connected to the portable air conditioner, and the other end of the exhaust pipe 300 is connected to the third connecting part 14 on the connector body 11. The connector body 11 is fixed to the window panel by the first fastening structure and the second fastening structure, so that the exhaust gas generated by the portable air conditioner can be discharged to the outside through the exhaust pipe, the air duct connector 100 and the window panel.

[0047] like Figures 1 to 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the connector body 11 includes an inner shroud 111 and an outer shroud 112 connected to the inner shroud 111. The diameter of the inner shroud 111 is smaller than the diameter of the assembly hole 201, and the diameter of the outer shroud 112 is larger than the diameter of the assembly hole 201. A height difference H1 is formed between the inner shroud 111 and the outer shroud 112.

[0048] In the above embodiments, the diameter of the inner shroud 111 is further defined as being smaller than the diameter of the mounting hole 201, so that the inner shroud 111 can partially penetrate the mounting hole 201; by forming a height difference H1 between the inner shroud 111 and the outer shroud 112, and by having the diameter of the outer shroud 112 larger than the diameter of the mounting hole 201, after the inner shroud 111 partially penetrates the mounting hole 201, the outer shroud 112 abuts against the mounting plate 200, preventing the mounting plate 200 from moving further relative to the connector body 11.

[0049] Both the outer plate 112 and the inner plate 111 can be tubular shell structures, and the diameter of the outer plate 112 is larger than the diameter of the inner plate 111. Based on the height difference H1 formed between the inner plate 111 and the outer plate 112, the inner plate 111 partially penetrates the mounting hole 201 and extends to the inner side of the mounting plate 200, while the outer plate 112 is completely stationary on the outer side of the mounting plate 200.

[0050] like Figures 2 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the second connecting part 13 has a block structure, the second connecting part 13 is distributed along the outer edge of the inner circumference plate 111, and the sum of the width of the second connecting part 13 and the diameter of the inner circumference plate 111 is greater than the diameter of the assembly hole 201, and the snap-fit ​​space between the second connecting part 13 and the outer circumference plate 112 forms a second fastening structure.

[0051] In the above embodiment, the second connecting part 13 is further defined to be distributed on the outer edge of the inner panel 111. The second connecting part 13 is a block structure, so that a snap-fit ​​space is formed between the second connecting part 13 and the outer panel 112. During the assembly process of the duct connector 100 and the mounting plate 200, the second connecting part 13 extends through the assembly hole 201 to the inner side of the mounting plate 200. Since the sum of the width of the second connecting part 13 and the diameter of the inner panel 111 is greater than the diameter of the assembly hole 201, the snap-fit ​​space formed between the second connecting part 13 and the outer panel 112 can be snap-fitted with the mounting plate 200.

[0052] The second connecting part 13 can be a block structure extending in the diameter direction of the outer plate 112. The second connecting part 13 has a certain width so that the second connecting part 13 can abut against the mounting plate 200.

[0053] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a plurality of first reinforcing ribs 131 are provided on the second connecting part 13 at intervals, the first reinforcing ribs 131 are respectively connected to the second connecting part 13 and the inner circumferential plate 111, and the height difference H2 between the first reinforcing ribs 131 and the outer circumferential plate 112 is less than the height difference H1 between the inner circumferential plate 111 and the outer circumferential plate 112.

[0054] In the above embodiments, the first reinforcing rib 131 is further defined to be connected to the second connecting part 13 and the inner circumference plate 111 respectively, which can improve the hardness of the second connecting part 13 and make it less prone to bending or breakage; in addition, since the height difference H2 between the first reinforcing rib 131 and the outer circumference plate 112 is smaller than the height difference H1 between the inner circumference plate 111 and the outer circumference plate 112, the mounting plate 200 can be clamped between the first reinforcing rib 131 and the outer circumference plate 112, reducing the shaking of the mounting plate 200 on the second fastening structure.

[0055] like Figure 1 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the shape of the second connecting part 13 is arc-shaped, and the arc length L1 of the second connecting part 13 satisfies: 0.3L2≤L1≤0.6L2, where L2 is the perimeter of the inner circumference plate 111.

[0056] The second connecting part 13 can be an arc-shaped block structure, the arc of which matches the cross-section of the inner shroud 111. The arc length L1 of the second connecting part 13 accounts for 30% to 60% of the perimeter L2 of the inner shroud 111. Based on the above design, it ensures that the second connecting part 13 has a certain contact area with the mounting plate 200, that the second connecting part 13 has sufficient rigidity, and that the second connecting part 13 is not too long, which would make it difficult for the second connecting part 13 to pass through the mounting hole 201; for example, the arc length L1 of the second connecting part 13 is 0.5L2.

[0057] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first clearance opening 101 is provided on the top of the outer perimeter plate 112, and the height difference H3 between the first clearance opening 101 and the second connecting part 13 is greater than the height difference H1 between the inner perimeter plate 111 and the outer perimeter plate 112.

[0058] The above embodiment further specifies that a first clearance opening 101 is provided on the top of the outer plate 112 to facilitate the user's hand to insert into the first clearance opening 101 to control the disassembly and assembly of the connector body 11 and the mounting plate 200.

[0059] Specifically, the first clearance opening 101 extends away from the second connecting part 13 and forms a groove structure. The groove structure is disposed opposite to the second connecting part 13 and is located below the second connecting part 13. Since the height difference H3 between the bottom of the groove and the second connecting part 13 is greater than the height difference H1 between the inner circumference plate 111 and the outer circumference plate 112, there is space between the mounting plate 200 and the bottom of the groove, which facilitates operation.

[0060] like Figure 1 , Figure 3 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines: the first connecting part 12 includes a first connecting segment 121, a second connecting segment 122 and a third connecting segment 123. The first connecting segment 121 is connected to the inner shroud 111 or the outer shroud 112. The second connecting segment 122 is bent relative to the first connecting segment 121. The third connecting segment 123 is bent relative to the second connecting segment 122. The second connecting segment 122 is provided with a snap-fit ​​part 124. The snap-fit ​​space between the snap-fit ​​part 124 and the outer shroud 112 forms a first fastening structure. The third connecting segment 123 is used to press the second connecting segment 122 to drive the snap-fit ​​part 124 to move toward the central axis of the mounting hole 201.

[0061] The above embodiments further define that the first connecting segment 121, the second connecting segment 122, and the third connecting segment 123 are bent and connected in sequence. Specifically, the second connecting segment 122 is bent relative to the first connecting segment 121, and the third connecting segment 123 is bent relative to the second connecting segment 122. When the third connecting segment 123 is pressed, the second connecting segment 122 is equivalent to the position of the first connecting segment 121 and forms at least a first position and a second position. Based on the fact that the second connecting segment 122 is provided with a snap-fit ​​part 124, and a snap-fit ​​space is formed between the second connecting part 13 and the third connecting part 14, when the second connecting segment 122 is in the first position, the first fastening structure is in a fastened state with the mounting plate 200. When the second connecting segment 122 moves from the first position to the second position, the first fastening structure is in a disengaged state with the mounting plate 200.

[0062] The snap-fit ​​part 124 can be an arc-shaped protrusion structure. Based on this design, the mounting plate 200 can be smoothly engaged or disengaged from the first snap-fit ​​structure.

[0063] It should be noted that the first connecting segment 121, the second connecting segment 122 and the third connecting segment 123 can be integrally formed structures, and the structure can be made of metal or plastic. When the third connecting segment 123 is pressed by an external force, the second connecting segment 122 is displaced relative to the first connecting segment 121. When the external force is removed, the second connecting segment 122 can recover its deformation on its own.

[0064] In addition, in some embodiments, a second clearance opening 102 may be provided on the outer plate 112. The second clearance opening 102 is disposed opposite to the first connecting part 12, and the second clearance opening 102 is recessed in the direction of the first connecting section 121 to form a groove structure, so that the third connecting section 123 has enough space to be pressed and moved in the direction of the central axis of the assembly hole 201.

[0065] like Figure 1 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a second reinforcing rib 125 is provided at the connection between the second connecting segment 122 and the third connecting segment 123, and the distance between the second reinforcing rib 125 and the snap-fit ​​portion 124 is less than the thickness of the mounting plate 200.

[0066] The above embodiments further specify that a second reinforcing rib 125 is provided between the second connecting segment 122 and the third connecting segment 123 to enhance the connection strength between the two and prevent the third connecting segment 123 from deforming relative to the second connecting segment 122 when the third connecting segment 123 is pressed, so that the second connecting segment 122 cannot deform normally and the snap-fit ​​part 124 fails. In addition, by providing the second reinforcing rib 125 in the third connecting part 14, the shaking of the mounting plate 200 on the first fastening structure can be reduced.

[0067] It should be noted that there can be multiple second reinforcing ribs 125, and multiple second reinforcing ribs 125 are distributed at intervals on the third connecting section 123.

[0068] like Figure 1 , Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the duct connector 100 also includes a ventilation grille 15, which is connected to the cavity of the duct connector 100.

[0069] The above embodiments further specify that a ventilation grille 15 is provided in the cavity of the duct connector 100, which can effectively prevent external dust, leaves, debris and small animals from entering the duct and avoid blockage; in addition, the ventilation grille 15 can reduce the noise generated during exhaust by dispersing airflow and reducing turbulence, thereby improving user comfort.

[0070] like Figure 6 As shown, this embodiment provides an exhaust assembly, including a mounting plate 200, an exhaust pipe 300, and the aforementioned duct connector 100. The mounting plate 200 has an assembly hole 201. The duct connector 100 at least partially penetrates the assembly hole 201 and is fastened to the mounting plate 200. One end of the exhaust pipe 300 is threaded to the third connecting part 14, and the other end is connected to the exhaust port of the portable air conditioner.

[0071] The exhaust assembly of this application has an exhaust pipe 300 connected to the exhaust port of the portable air conditioner and the third connecting part 14 respectively. The mounting plate 200 can be used as a window panel, thereby fixing the exhaust pipe to the window. When the portable air conditioner is working, the exhaust gas generated is discharged to the outside through the exhaust pipe and the duct connector 100 in sequence.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
