[0041] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] Hereinafter, a fresh air duct connector 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0043] like Figure 1-Figure 12 As shown, the fresh air duct connector 100 according to an embodiment of the present invention includes: a connector body 1, one end of the connector body 1 is a mounting end 1a and the mounting end 1a has a first connecting structure 14 for connecting to the air conditioner 200, the connector body 1 includes a plurality of connector pipe sections 10 whose pipe diameters decrease successively in a direction away from the mounting end 1a, and each connector pipe section 10 has a second connecting structure 15 for connecting to the fresh air duct 300.

[0044] Therefore, the fresh air duct connector 100 can be installed with fresh air ducts 300 of different diameters, thereby improving the versatility of the fresh air duct connector 100 .

[0045] For example, Figure 1-Figure 7 As shown, the fresh air pipe joint 100 is used to connect and communicate the air conditioner 200 with the fresh air pipe 300, so that the external air can flow through the fresh air pipe 300 and the fresh air pipe joint 100 to flow into the air conditioner 200, thereby realizing the fresh air function of the air conditioner 200. The air conditioner 200 here can be an indoor unit of a split air conditioner, or an integrated air conditioner (such as a kitchen air conditioner, a mobile air conditioner).

[0046] The fresh air duct connector 100 includes a connector body 1, which is constructed in a tubular shape. One end of the connector body 1 along the axial direction is set as a mounting end 1a and has a first connecting structure 14 on the mounting end 1a. The first connecting structure 14 is used to connect to the air conditioner 200 to connect the mounting end 1a of the connector body 1 to the air conditioner 200.

[0047] The connector body 1 includes a plurality of connector pipe segments 10 sequentially distributed along the axial direction, such as a first connector pipe segment 11, a second connector pipe segment 12, and a third connector pipe segment 13. The plurality of connector pipe segments 10 are constructed so that the pipe diameters decrease in sequence in the direction away from the mounting end 1a. The connector pipe segments 10 of different pipe diameters are used to match the fresh air ducts 300 of different pipe diameters. For example, it can match the fresh air duct 300 that adopts a punch-free installation method, or it can match the fresh air duct 300 that adopts a hole expansion installation method, or it can match the fresh air duct 300 that adopts a punching installation method, and the present application does not limit this. At the same time, each connector pipe segment 10 has a second connection structure 15, and the second connection structure 15 is used to connect to the fresh air duct 300, so as to connect the fresh air ducts 300 of different pipe diameters to the fresh air duct connector 100.

[0048] In the specific installation process, if the joint pipe section 10 corresponding to the fresh air duct 300 is not the one with the smallest diameter, the redundant joint pipe section 10 located on the side of the corresponding joint pipe section 10 away from the installation end 1a can be cut off, and then the fresh air duct 300 is plugged into the corresponding joint pipe section 10 from the other end of the fresh air duct joint 100, so that the second connection structure 15 on the corresponding joint pipe section 10 can be connected to the fresh air duct 300, thereby realizing the simple installation of the fresh air duct 300 and the air conditioner 200. Of course, the fresh air duct 300 can also be directly sleeved on the corresponding joint pipe section 10 from the other end of the fresh air duct joint 100, and this application does not limit this. In this way, the versatility of the fresh air duct joint 100 is improved.

[0049] It should be noted that the second connection structure 15 can be disposed on the outer peripheral wall of the joint pipe section 10 , or can be disposed in the lumen of the joint pipe section 10 , and the present application does not impose any limitation on this.

[0050] According to the fresh air duct connector 100 of the embodiment of the present invention, the connector body 1 is provided with a plurality of connector pipe sections 10 with different pipe diameters, and the plurality of connector pipe sections 10 with different pipe diameters can be respectively matched with the fresh air ducts 300 with different pipe diameters, so that the fresh air duct connector 100 can be installed with the fresh air ducts 300 with different pipe diameters, thereby improving the versatility of the fresh air duct connector 100 and helping to reduce the installation difficulty and installation cost of the fresh air duct 300.

[0051] In some embodiments of the present invention, the plurality of joint pipe segments 10 include a first joint pipe segment 11, a second joint pipe segment 12 and a third joint pipe segment 13, the pipe diameter R1 of the first joint pipe segment 11 is 60 mm to 150 mm, the pipe diameter R2 of the second joint pipe segment 12 is 40 mm to 100 mm, and the pipe diameter R3 of the third joint pipe segment 13 is 30 mm to 40 mm.

[0052] For example, refer to Figure 1-Figure 7 As shown, a plurality of joint pipe segments 10 may be provided, including a first joint pipe segment 11, a second joint pipe segment 12 and a third joint pipe segment 13. The first joint pipe segment 11, the second joint pipe segment 12 and the third joint pipe segment 13 are sequentially arranged in a direction away from the installation end 1a and the pipe diameters decrease accordingly. Among them, the pipe diameter of the first joint pipe segment 11 may be set to R1, satisfying: 60mm≤R1≤150mm, such as the pipe diameter R1 of the first joint pipe segment 11 may be taken as 70mm, or the pipe diameter R1 of the first joint pipe segment 11 may be taken as 105mm, or the pipe diameter R1 of the first joint pipe segment 11 may be taken as 140mm, and the present application does not impose any restrictions on this. It should be noted that, if Figure 4-Figure 5 As shown, when the fresh air duct 300 is installed by punching, a hole (usually with a diameter of 60 mm to 150 mm) is usually opened in the wall 2000 for the installation of the fresh air duct 300, and the diameter range of the fresh air duct 300 is usually set to 60 mm to 150 mm. In this way, the first joint pipe section 11 can be matched with the fresh air duct 300 by limiting the pipe diameter of the first joint pipe section 11 within the above range, so that the first joint pipe section 11 can be connected to the fresh air duct 300 installed by punching.

[0053] At the same time, the diameter of the second joint pipe section 12 can be set to R2, satisfying: 40mm≤R1≤100mm, such as the diameter R2 of the second joint pipe section 12 can be set to 50mm, or the diameter R2 of the second joint pipe section 12 can be set to 70mm, or the diameter R2 of the second joint pipe section 12 can be set to 90mm, and this application does not limit this. It should be noted that, if Figure 6-Figure 7 As shown, when the fresh air duct 300 is installed by expanding the hole, the original hole on the wall 2000 is usually expanded, and the fresh air duct 300 and the pipeline 400 are inserted into the expanded hole (usually with a diameter of 80mm to 120mm). At this time, the diameter range of the fresh air duct 300 is usually 40mm to 100mm. In this way, the second joint pipe section 12 can be matched with the fresh air duct 300 by limiting the pipe diameter of the second joint pipe section 12 within the above range, so that the second joint pipe section 12 can be connected to the fresh air duct 300 installed by expanding the hole.

[0054] At the same time, the diameter of the third joint pipe section 13 can be set to R3, satisfying: 30mm≤R1≤40mm, such as the diameter R3 of the third joint pipe section 13 can be set to 32mm, or the diameter R3 of the third joint pipe section 13 can be set to 35mm, or the diameter R3 of the third joint pipe section 13 can be set to 38mm, and this application does not impose any restrictions on this. It should be noted that when the fresh air duct 300 adopts a punch-free installation method, the fresh air duct 300 and the pipeline 400 are directly penetrated in the original hole (usually with a diameter of 60mm to 65mm). At this time, the diameter range of the fresh air duct 300 is usually 30mm to 40mm. In this way, the diameter of the third joint pipe section 13 can be limited to the above range, so that the third joint pipe section 13 can be matched with the fresh air duct 300, so that the third joint pipe section 13 can be connected to the fresh air duct 300 that adopts a punch-free installation method.

[0055] For example, the diameter R1 of the first joint pipe section 11 can be 120 mm, the diameter R2 of the second joint pipe section 12 can be 80 mm, and the diameter R3 of the third joint pipe section 13 can be 40 mm. The above embodiments are merely exemplary and do not limit the present application.

[0056] Through the above-mentioned setting, the fresh air duct connector 100 can be connected to the fresh air duct 300 which adopts the punching-free installation method, the fresh air duct 300 which adopts the hole expansion installation method and the fresh air duct 300 which adopts the punching installation method, which is conducive to meeting different installation requirements and improves the practicality of the fresh air duct connector 100.

[0057] In some embodiments of the present invention, the first connecting structure 14 includes a rotating buckle 141, which is fixed on the outer wall of the connector body 1. When the mounting end 1a is inserted into the mounting hole of the air conditioner 200 and rotated to a locked position, the rotating buckle 141 is engaged with the air conditioner 200.

[0058] For example, refer to Figure 8-Figure 11 As shown, the first connection structure 14 may include a rotating buckle 141, which is fixed on the outer peripheral wall of the joint body 1. At the same time, a mounting frame 201 may be provided on the air conditioner 200, and a mounting hole is formed on the mounting frame 201. The mounting hole is matched with the mounting end 1a of the joint body 1, so that the mounting end 1a of the joint body 1 can be inserted into the mounting hole, and the joint body 1 is configured to be rotatable relative to the mounting frame 201. The mounting frame 201 is provided with a fixing buckle 202 at the edge position surrounding the mounting hole. When the joint body 1 is rotated to a locking position relative to the mounting frame 201, the fixing buckle 202 can be connected with the rotating buckle 141 to fix the joint body 1 on the air conditioner 200.

[0059] Through the above arrangement, the fresh air duct connector 100 and the air conditioner 200 can be conveniently installed, the difficulty of installing the fresh air duct connector 100 is reduced, and the practicality of the fresh air duct connector 100 is improved.

[0060] In some embodiments of the present invention, the first connecting structure 14 includes a connecting boss 142, which is fixed on the outer peripheral wall of the connector body 1. The connecting boss 142 is provided with a first connecting hole 1421, and the connector body 1 is suitable for being connected to the air conditioner 200 via a first fastener passing through the first connecting hole 1421.

[0061] For example, refer to Figure 8 and Fig.11 As shown, the first connection structure 14 includes a connection boss 142, which is fixed on the outer peripheral wall of the joint body 1 and protrudes outward along the radial direction of the joint body 1, and a first connection hole 1421 is provided on the connection boss 142. At the same time, a mounting seat 203 can be provided on the mounting frame 201, and the mounting seat 203 is arranged opposite to the connection boss 142 and is formed with a first mounting hole. When the fresh air duct joint 100 is supported on the mounting frame 201, the first mounting hole can be directly opposite to the first connecting hole 1421. At this time, the joint body 1 and the mounting frame 201 can be locked by passing the first fastener through the first connecting hole 1421 and extending into the first mounting hole. Specifically, the first fastener can be constructed as a screw, and the first mounting hole can be constructed as a threaded hole. In this way, the stable installation of the fresh air duct joint 100 and the air conditioner 200 can be achieved, and the reliability of the fresh air duct joint 100 is improved.

[0062] In some embodiments of the present invention, the first connecting structure 14 includes a connecting boss 142, which is fixed on the outer peripheral wall of the connector body 1. The connecting boss 142 and the rotating buckle 141 are arranged at intervals along the circumference of the connector body 1. The connecting boss 142 is provided with a first connecting hole 1421. The connector body 1 is suitable for being connected to the air conditioner 200 through a first fastener passing through the first connecting hole 1421 when the mounting end 1a is rotated to a locking position.

[0063] For example, refer to Figure 8-Figure 11 As shown, the first connection structure 14 includes a connection boss 142, which is fixed on the outer peripheral wall of the joint body 1 and protrudes outward along the radial direction of the joint body 1. The connection boss 142 and the rotating buckle 141 are spaced apart along the circumference of the joint body 1, and a first connection hole 1421 is provided on the connection boss 142. At the same time, a mounting seat 203 can be provided on the mounting frame 201, and the mounting seat 203 is arranged opposite to the connection boss 142 and is formed with a first mounting hole, and the first mounting hole is arranged opposite to the first connection hole 1421.

[0064] In the specific installation process, the installation end 1a of the joint body 1 can be first inserted into the installation hole, and the installation end 1a of the joint body 1 can be driven to rotate to the locking position, so that the rotating buckle 141 is snap-connected with the fixing buckle 202 of the mounting frame 201. At this time, the first installation hole is directly opposite to the first connecting hole 1421, and the first fastener can be passed through the first connecting hole 1421 and extended into the first installation hole to lock the joint body 1 and the mounting frame 201. In this way, the double locking of the air conditioner 200 and the fresh air duct joint 100 can be achieved, which is conducive to improving the installation stability of the fresh air duct joint 100.

[0065] In some embodiments of the present invention, the second connection structure 15 includes a second connection hole 151 that penetrates the joint pipe section 10 . The joint pipe section 10 is suitable for plugging and matching with the fresh air duct 300 and is connected to the fresh air duct 300 via a second fastener 2 that passes through the second connection hole 151 .

[0066] For example, refer to Figure 8-Figure 11As shown, the second connection structure 15 includes a second connection hole 151, which passes through the joint pipe section 10 in the radial direction (it can also form a certain angle with the radial direction), and a second mounting hole can be provided on the fresh air duct 300 corresponding to the second connection hole 151. When the fresh air duct 300 is plugged and matched with the joint pipe section 10, the second connection hole 151 can be directly opposite to the second mounting hole. At this time, the second fastener 2 can be inserted into the second mounting hole and the second connection hole 151 to achieve convenient installation of the fresh air duct 300 and the joint pipe section 10. Specifically, the second fastener 2 can be constructed as a screw, and the second connection hole 151 can be constructed as a threaded hole. In this way, the fresh air duct joint 100 and the fresh air duct 300 can be conveniently installed, which improves the practicality of the fresh air duct joint 100.

[0067] In some embodiments of the present invention, Fig.10 As shown, the second connection hole 151 can be set to multiple, and the multiple second connection holes 151 are arranged at intervals along the circumference of the joint pipe section 10. At the same time, multiple second mounting holes can be provided on the fresh air duct 300, and the multiple second mounting holes correspond to the multiple second connection holes 151 one by one. A second fastener 2 is inserted in each group of second connection holes 151 and second mounting holes, and the multiple second fasteners 2 can jointly limit the fresh air duct 300. This is conducive to improving the installation stability between the fresh air duct 300 and the fresh air duct joint 100, and improving the reliability of the fresh air duct joint 100.

[0068] In some embodiments of the present invention, the second connection structure 15 includes a threaded structure and / or a snap-fit ​​structure. For example, the second connection structure 15 can be provided to include a threaded structure, the threaded structure can be constructed as an external thread, and an internal thread can be formed in the tube cavity of the fresh air duct 300, and the fresh air duct 300 and the fresh air duct joint 100 can be stably installed by plugging and matching the fresh air duct 300 with the joint pipe section 10 so that the internal thread and the external thread are screwed together; or, the second connection structure 15 can be provided to include a snap-fit ​​structure, and a slot structure is provided in the tube cavity of the fresh air duct 300, and the fresh air duct 300 and the fresh air duct joint 100 can be stably installed by plugging and matching the fresh air duct 300 with the joint pipe section 10 so that the snap-fit ​​structure and the slot structure are snap-fitted together; or, the second connection structure 15 can be provided to include a threaded structure and a snap-fit ​​structure, and the snap-fit ​​structure is suitable for snap-fitting with the fresh air duct 300 after the threaded structure is connected to the fresh air duct 300, and the present application does not limit this. This helps to meet different working conditions.

[0069] In some embodiments of the present invention, a notch groove 16 is provided at the end of the one with a larger pipe diameter in two adjacent joint pipe sections 10 near the other, and the notch groove 16 extends along the circumference of the joint pipe section 10 so that the joint body 1 is suitable for being cut at the notch groove 16, and the second connecting structure 15 on the same joint pipe section 10 is located on the side of the notch groove 16 close to the installation end 1a.

[0070] For example, refer to Figure 9-10 As shown, a notch groove 16 can be provided at the end of the one with a larger diameter in two adjacent joint pipe sections 10 near the other, and the notch groove 16 extends along the circumference of the joint pipe section 10 and is arranged inwardly concave, so that the joint body 1 is suitable for cutting at the notch groove 16, reducing the difficulty of cutting the fresh air pipe joint 100. At the same time, the second connection structure 15 on the same joint pipe section 10 can be arranged to be located on the side of the notch groove 16 close to the installation end 1a, which can prevent the second connection structure 15 from being cut off and causing the fresh air pipe joint 100 to fail. Therefore, the design rationality of the fresh air pipe joint 100 is improved.

[0071] In some embodiments of the present invention, the wall thickness W of the joint pipe section 10 at the notch 16 is 0.4 mm to 2 mm. For example, the wall thickness W of the joint pipe section 10 at the notch 16 can be set to W, satisfying: 0.4 mm ≤ W ≤ 2 mm, such as the wall thickness W of the joint pipe section 10 at the notch 16 can be set to 0.6 mm; or, the wall thickness W of the joint pipe section 10 at the notch 16 can be set to 1.2 mm; or, the wall thickness W of the joint pipe section 10 at the notch 16 can be set to 1.8 mm, and this application does not impose any restrictions on this.
