[0034] In related technologies, to meet users' requirements for air quality, air conditioners (such as indoor air conditioners, integrated air conditioners, or fresh air systems) are equipped with a fresh air function to guide fresh outdoor air into the room. Specifically, air conditioners introduce outdoor air through fresh air ducts extending to the outside. To prevent outdoor debris, rodents, and other pests from entering the room through the fresh air ducts, rodent-proof screens are usually installed on the ducts. However, this can easily affect the air intake volume of the fresh air ducts.

[0035] To solve this technical problem, this utility model proposes a new type of air duct.

[0036] Please see Figures 1 to 3 In one embodiment of this utility model, the fresh air duct includes a duct body 10 and a protective net 20. The duct body 10 is used to connect to the fresh air interface of an air conditioner. The protective net 20 is located at the end of the duct body 10 away from the fresh air interface. The protective net 20 includes a connecting section 22 and a protective spiral section 21 connected together. The connecting section 22 is fixed to the outer wall of the duct body 10. The protective spiral section 21 protrudes from the end of the duct body 10, and its spiral diameter decreases in the direction away from the duct body 10. This increases the air intake of the fresh air duct while the protective net 20 provides protection, thereby further improving the freshness of the indoor air.

[0037] In the technical solution of this utility model, a protective net 20 is provided at the end of the duct body 10 away from the fresh air interface to prevent debris, rodents, etc. from entering the room through the fresh air duct, thereby improving the reliability of the air conditioner. The protective net 20 includes a connecting section 22 and a protective spiral section 21 connected together. The connecting section 22 is fixed to the outer wall of the duct body 10 and can support and protect the end of the duct body 10 away from the fresh air interface to a certain extent, and realize the reliable assembly of the protective net 20. The protective spiral section 21 extends away from the duct body 10 from the end protruding from the duct body 10. In this process, the diameter of the spiral line of the protective spiral section 21 is reduced, that is, the spiral line of the protective spiral section 21 is a three-dimensional conical spiral line. Compared with the spiral line of the protective spiral section 21 being a planar spiral line, the protective spiral section 21 has air inlet gaps on the side and top surfaces, increasing the air inlet area of ​​the protective net 20, which in turn helps to increase the air intake of the fresh air duct, thereby further improving the freshness of the indoor air.

[0038] It should be noted that, typically, air conditioners are installed indoors. In this case, the fresh air duct extends outdoors through a wall opening, allowing the air conditioner's fresh air inlet to connect to the outdoor environment, thus refreshing the indoor air. The air conditioner includes an indoor unit, which comprises a casing and a fresh air module housed within the casing. The fresh air module contains a fresh air duct and a fresh air inlet connecting to the duct, which is connected to the fresh air duct. Alternatively, the indoor unit may include a casing and a fresh air duct formed within the casing, with the duct connected to the fresh air duct via the fresh air inlet.

[0039] Please see Figures 1 to 2 In the embodiments of this utility model, in the direction away from the pipe body 10, the pitch of each thread on the protective spiral segment 21 is gradually reduced, that is, the specific size of each thread pitch gradually decreases in the direction away from the pipe body 10, which helps to improve the stability of the protective spiral segment 21, reduce the possibility of deformation of the protective spiral segment 21, and improve the protective effect of the protective net 20.

[0040] Specifically, in the embodiments of this utility model, the pitch on the protective spiral section 21 is P1, where 0mm < P1 < 10mm. It can be understood that this pitch is the air inlet gap on the side of the protective spiral section 21. By limiting the pitch P1 to between 0 and 10mm, it is possible to avoid the air inlet area of ​​the fresh air duct being affected by the small air inlet gap, which helps to improve the air intake of the fresh air duct. It is also possible to avoid the rigidity of the protective spiral section 21 being affected by the large pitch, which helps to improve the rigidity of the protective spiral section 21. This, in turn, prevents the protective spiral section 21 from becoming unstable under pressure, thereby improving the protective effect of the protective net 20 against debris, rats, and insects.

[0041] Specifically, the pitch P1 on the protective spiral section 21 may take values ​​including, but not limited to, 2.5mm, 3.8mm, 4mm, 4.9mm, 5mm, and 6.1mm. However, this design is not limited to this. In other embodiments, the pitch on the protective spiral section 21 may be greater than or equal to 10mm and less than or equal to 15mm.

[0042] In addition, while ensuring the rigidity and protective effect of the protective spiral section 21, the length of the protective spiral section 21 in the length direction of the pipe body 10 can be greater than or equal to 19 mm and less than or equal to 22 mm; in one embodiment of the present invention, the length of the protective spiral section 21 in the length direction of the pipe body 10 is 20.5 mm.

[0043] Please see Figures 1 to 2In an embodiment of this utility model, the outer wall of the pipe body 10 is provided with ribs 11 extending spirally along its length. The connecting segment 22 is wound around the pipe body 10 and located within the groove 12 formed by the pipe body 10 and the ribs 11. It can be understood that because the outer wall of the pipe body 10 is provided with ribs 11 extending spirally along its length, the pipe body 10 is a pipe body 10 with external threads, and two adjacent threads together with the outer wall of the pipe body 10 form a groove 12 extending spirally along the length of the pipe body 10, which helps to strengthen the pipe. The structural strength of the main body 10 is enhanced by the connecting segment 22 winding around the outer wall of the main body 10 to form a spiral structure. The spiral line of this structure is adapted to the main body 10, and when the main body 10 is a round tube, it is configured as a cylindrical spiral line. In this case, the connecting segment 22 is wound along the groove 12, so that the connecting segment 22 is limited and installed in the groove 12. This helps to improve the connection reliability between the protective net 20 and the main body 10, reduce the possibility of the protective net 20 separating from the main body 10, and also helps to improve the connection convenience and efficiency between the protective net 20 and the main body 10. However, this design is not limited to this. In other embodiments, the outer wall of the main body 10 is provided with a fastener for the connecting segment 22 to pass through. Through the cooperation of the connecting segment 22 with the fastener, or the interference fit between the main body 10 and the connecting segment 22, the assembly of the protective net 20 on the main body 10 can also be achieved.

[0044] Specifically, in the embodiments of this utility model, the pitch of the thread at any position on the connecting segment 22 is equal. This arrangement facilitates the processing of the ribs 11 on the pipe body 10 and also ensures the overall rigidity and stability of the connecting segment 22, thereby improving the reliability of the protective net 20 connected to the pipe body 10 through the connecting segment 22.

[0045] The pitch of the connecting segment 22 is P2, where P2 ≥ 10 mm. Specifically, the specific values ​​of the pitch P2 of the connecting segment 22 include, but are not limited to, 10 mm, 10.5 mm, 11 mm, 11.8 mm, and 12 mm. However, this design is not limited to this. In other embodiments, the pitch of the connecting segment 22 is greater than or equal to 8 mm and less than or equal to 15 mm. In one embodiment of this utility model, the pitch of the connecting segment 22 is 10 mm.

[0046] Optionally, in an embodiment of this utility model, the protective net 20 is formed by spiraling a single metal wire, i.e., the connecting section 22 and the protective spiral section 21 are integrally formed; this facilitates the processing and manufacturing of the protective net 20 and saves processing costs; of course, in other embodiments, the connecting section 22 and the protective spiral section 21 are fixed into a whole by welding or other connection methods, which facilitates the separate processing of the connecting section 22 and the protective spiral section 21 to adapt to the different shapes of the connecting section 22 and the protective spiral section 21.

[0047] Specifically, the protective net 20 is configured as a rodent-proof spring; wherein, the metal wire can be spring steel, which can give the protective net 20 excellent comprehensive performance and elasticity, thereby improving the protective effect and service life of the protective net 20.

[0048] Optionally, in an embodiment of this utility model, the pipe body 10 is configured as a PVC pipe or a PU pipe. It is understood that the pipe body 10 is configured as a plastic pipe, which can be a PVC pipe or a PU pipe, and its wall thickness can be greater than or equal to 0.5 mm. However, in other embodiments, the pipe body 10 can also be configured as a metal pipe or a composite flexible hose.

[0049] Optionally, in an embodiment of this utility model, the fresh air duct further includes a fresh air connector. One end of the duct body 10 is threaded to the fresh air connector via the rib 11. The fresh air connector is used to connect to the fresh air interface. It is understood that the outer wall of the duct body 10 is provided with ribs 11 extending spirally along the length of the duct body 10. These ribs 11 form an external thread on the duct body 10. In this case, the fresh air connector is provided with an internal thread that mates with the external thread, thus enabling quick installation of the fresh air connector and the duct body 10. However, this design is not limited to this. In other embodiments, the duct body 10 and the fresh air connector can be detachably connected via a snap-fit ​​structure, clamp, or rotary snap structure, thereby improving the ease of assembly and disassembly of the duct body 10 and the fresh air connector.

[0050] Please see Figures 1 to 2 In an embodiment of this utility model, the fresh air duct further includes an insulating sleeve 30 fitted over the duct body 10. The connecting section 22 of the protective net 20 is located between the duct body 10 and the insulating sleeve 30. On the one hand, the insulating sleeve 30 provides support to the duct body 10, thereby enhancing the overall structural strength of the fresh air duct. On the other hand, by placing the insulating sleeve 30 outside the connecting section 22, it helps to further constrain the tendency of the protective net 20 to detach from the duct body 10, improving the connection reliability between the protective net 20 and the duct body 10. Simultaneously, it also ensures that the fresh air duct has good thermal insulation performance, reducing the possibility of condensation on the inner wall surface of the fresh air duct.

[0051] Wherein, the insulation sleeve 30 is configured as a PE sleeve; and / or the insulation sleeve 30 is configured as an embossed leather sleeve; and / or the insulation sleeve 30 is configured as insulation cotton. However, in other embodiments, the material of the insulation sleeve 30 includes, but is not limited to, XPE, rubber and plastic insulation materials, glass wool, rock wool, and polyurethane foam.

[0052] The wall thickness of the insulation sleeve 30 can be greater than or equal to 2mm, which can reduce the material usage of the insulation sleeve 30 while ensuring the air intake and insulation performance of the fresh air duct.
