[0033] Air ducts are pipes used to transport air and are widely used in industrial and construction fields. Their main functions include air transport, airflow regulation, and air separation. Air duct maintenance is crucial, requiring regular cleaning and replacement of damaged parts to ensure proper operation and extend the duct's lifespan. However, most current air ducts are difficult to position and secure during installation, and disassembly and installation are quite inconvenient.

[0034] Based on this, please refer to Figure 1 and Figure 2 The air duct 1000 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems. The air duct 1000 can be installed and disassembled quickly and conveniently. The air duct 1000 can be applied to equipment such as air conditioners and heat pumps; all equipment with the air duct 1000 has the same functions as described above, and will not be elaborated further here.

[0035] The air conditioner in this embodiment includes a compressor, an evaporator, a condenser, a throttling device, and an air duct 1000 connecting all structural components. The refrigerant is compressed into a high-temperature, high-pressure gas in the compressor, then dissipates heat through the condenser and becomes a liquid. After being depressurized and cooled by the throttling device, it enters the evaporator. The refrigerant in the evaporator absorbs heat from the room and is then drawn back into the compressor for compression. This cycle repeats continuously to achieve a cooling effect. Of course, the air conditioner may also include other structures such as a fan, depending on the usage requirements and functions, and is not limited here.

[0036] Figure 1 This is an exploded schematic diagram of the air duct 1000 provided in an embodiment of this utility model; Figure 2 This is a cross-sectional schematic diagram of the air duct 1000 provided in an embodiment of the present invention, as shown below. Figure 1 and Figure 2As shown, the air duct 1000 in this embodiment includes an air ring 100 and a panel 200. The air ring 100 has a first air hole 110 and a first limiting notch 120, which is provided with a first mounting part 121. The panel 200 has a second air hole 220 and a first limiting protrusion 210, which is provided with a second mounting part 211. The first limiting protrusion 210 and the first limiting notch 120 cooperate to limit each other, so that the first mounting part 121 and the second mounting part 211 are correspondingly arranged and the second air hole 220 and the first air hole 110 are correspondingly arranged. The first mounting part 121 and the second mounting part 211 are detachably connected. By setting a first limiting notch 120 and a first limiting protrusion 210 that mates with the first limiting notch 120, the first limiting notch 120 and the first limiting protrusion 210 can quickly position and limit the fan ring 100 during installation, allowing operators to align the fan ring 100 and the mounting portion of the panel 200 for rapid installation. Furthermore, mounting portions are provided at the first limiting protrusion 210 and the first limiting notch 120, allowing for detachable connection. This ensures the overall structural strength of the air duct 1000 while enhancing the stability of the connection between the fan ring 100 and the panel 200, and also enables rapid installation and disassembly. After the fan ring 100 and the panel 200 are fixed in place by the engagement of the first limiting notch 120 and the first limiting protrusion 210, the first mounting portion 121 and the second mounting portion 211 are aligned. Threaded fasteners such as bolts 500 pass through the first mounting portion 121 and are screwed into the second mounting portion 211 to connect the fan ring 100 and the panel 200.

[0037] By providing a first limiting notch 120 and a first limiting protrusion 210 that mates with the first limiting notch 120, the first limiting notch 120 and the first limiting protrusion 210 can quickly position and limit the air shroud 100 during installation, allowing operators to align the air shroud 100 with the mounting portion of the panel 200. Furthermore, the mounting portions at the first limiting protrusion 210 and the first limiting notch 120 allow for detachable connection, ensuring the overall structural strength of the duct 1000 while enhancing the stability of the connection between the air shroud 100 and the panel 200, and enabling rapid installation and disassembly. To facilitate connection of the duct 1000 with other ducts 1000 or ventilation equipment, connection interfaces can be provided at both ends of the duct 1000. Additionally, to ensure the airtightness of the duct 1000 connection and prevent air leakage, the connection interfaces can employ a sealed structure.

[0038] The aforementioned "a first limiting notch 120 is provided on the wind ring 100; a first limiting protrusion 210 that cooperates with the first limiting notch 120 is provided on the panel 200" specifically refers to the fact that in this embodiment, there are multiple first limiting notches 120 and first limiting protrusions 210. The multiple first limiting notches 120 are evenly distributed circumferentially on the wind ring 100; the multiple first limiting protrusions 210 are evenly distributed circumferentially on the panel 200; and the multiple first limiting notches 120 and multiple first limiting protrusions 210 correspond one-to-one. In this embodiment, the wind ring 100 is cubic in shape, and there are four first limiting notches 120 and four second limiting notches 230. The four first limiting notches 120 are located at the four corners of the cubic wind ring 100, and the second limiting notches 230 are correspondingly provided on the panel 200. Of course, the number of first limiting notches 120 and first limiting protrusions 210 can also be two, three, five, etc., and is not limited here. The shape of the wind ring 100 can also be a cuboid, a cylinder, etc., and is not limited here.

[0039] Figure 3 This is a schematic diagram of the wind ring 100 provided in an embodiment of this utility model. Please continue reading. Figure 1 and Figure 2 and combined Figure 3 The first limiting notch 120 has a regular shape, including triangles, circles, and squares. In this embodiment, the first limiting notch 120 is triangular, and correspondingly, the first limiting protrusion 210 is triangular. Of course, the first limiting notch 120 can also be rectangular or irregular, such as an irregular polygon, and the first limiting body is a matching shape.

[0040] Because the airtightness of the 1000 duct is extremely important, poor sealing often occurs at the joints. Therefore, please refer to... Figure 1 and Figure 2 and combined Figure 3In this embodiment, the air duct 1000 also includes a sealing strip 400. The air ring 100 has a groove 140 for placing the sealing strip 400, thus achieving a sealed connection between the air ring 100 and the panel 200. Specifically, the air ring 100 also has a groove 140 on the side with the first limiting notch 120, for placing the sealing strip 400. The sealing strip 400 uses a special adhesive that can firmly adhere to the surface of the air duct 1000, effectively preventing gas and liquid leakage and ensuring the sealing performance of the air duct 1000. Good sealing performance can reduce gas and liquid leakage, improve system efficiency, and thus save energy consumption. Furthermore, the sealing strip 400 is self-adhesive, easy to install, and can greatly improve work efficiency and reduce installation time. In addition, by filling the gaps in the air duct 1000 system, the sealing strip 400 can reduce the transmission of wind noise and other noise, providing a quiet working environment for systems such as air conditioning. By providing sealing elements such as sealing strips 400 at the connection between the air duct 100 and the panel 200, the sealing performance of the air duct 1000 can be improved.

[0041] Figure 4 For a schematic diagram of the panel 200 provided in an embodiment of this utility model, please refer to [link / reference]. Figure 1 and Figure 2 and combined Figure 4 The aforementioned "detachable connection between the first mounting part 121 and the second mounting part 211" specifically refers to the fact that the air duct 1000 in this embodiment also includes a bolt 500. The first mounting part 121 is provided with a threaded hole, and the second mounting part 211 is provided with a nut 300. The bolt 500 is used to engage with the nut 300 through the threaded hole. In this embodiment, the nut 300 is a weld nut. Of course, the bolt 500 can also be replaced with a set screw. Both the first mounting part 121 and the second mounting part 211 are provided with threaded holes. In addition, the first limiting protrusion 210 includes a support part and a connecting part. The support part is connected to the panel 200, and the connecting part is connected to the support part. The connecting part and the connecting surface of the panel 200 and the support part are arranged parallel, and there is a gap between the connecting part and the panel 200. The weld nut is provided on the side of the connecting part facing the gap. This design not only leaves room for the installation of the weld nut, but also satisfies the limiting and fixing with the first limiting notch 120, and also saves materials and reduces costs. Of course, in addition to setting a welded nut on the first limiting protrusion 210 to improve the connection strength, a locking washer or a quick-release buckle can also be set on the first limiting protrusion 210 to replace the welded nut. The decision is made according to the actual installation situation and is not limited here.

[0042] To ensure that the first air vent 110 and the second air vent 220 are aligned during installation, please refer to [link / reference needed]. Figure 1 and Figure 2 and combined Figure 3 and Figure 4 In this embodiment, the panel 200 has a second limiting notch 230, which communicates with the second air vent 220; the fan ring 100 has a second limiting protrusion 130 that mates with the second limiting notch 230. During installation, the second limiting protrusion 130 on the fan ring 100 is first used to hold the fan ring 100 against the second limiting notch 230 on the panel 200 for positioning, aligning the first air vent 110 and the second air vent 220, making the first air vent 110 and the second air vent 220 coaxial, preventing misalignment between the fan ring 100 and the panel 200, so as to facilitate the next step of connection and fixation. In this embodiment, the second limiting notch 230 is square, rectangular, or rectangular. Correspondingly, the second limiting protrusion 130 on the fan ring 100 is cuboid or cube-shaped. Of course, the second limiting notch 230 can also be designed as a semi-circle, triangle, or other regular or irregular shape. There are no limitations here, as long as it allows for quick alignment of the first air hole 110 of the fan ring 100 and the second air hole 220 of the panel 200 with a coaxial axis for subsequent installation. Alternatively, a second limiting notch 230 communicating with the first air hole 110 can be provided on the fan ring 100, and a second limiting protrusion 130 matching the second limiting notch 230 can be provided on the panel 200.

[0043] For further assistance with limiting and positioning, please refer to [link / reference needed]. Figure 1 and Figure 2 and combined Figure 3 and Figure 4 In this embodiment, the fan ring 100 is provided with a first engaging portion, and the panel 200 is provided with a second engaging portion. The first engaging portion and the second engaging portion engage with each other to assist in limiting the movement and prevent the fan ring 100 from rotating relative to the panel 200. Specifically, in this embodiment, the fan ring 100 has a slot, and the panel 200 has a buckle that engages with the slot. Of course, a buckle structure can also be provided on the fan ring 100, and a slot matching the buckle structure can be provided on the panel 200.

[0044] Traditionally, most air ducts (1000) are made of metal, which is costly. Compared to some lightweight materials, sheet metal is inherently more expensive, and its processing costs are also high. Furthermore, the fabrication of sheet metal air ducts (1000) typically requires specialized equipment and technicians for cutting, bending, and welding, further increasing costs. In addition, metal has good thermal conductivity but poor insulation, easily leading to heat exchange between the air inside the air duct and the outside environment, thus reducing the efficiency of the air conditioning or ventilation system. Moreover, metal air ducts (1000) have poor noise reduction. During airflow, sheet metal air ducts (1000) tend to generate significant noise, disturbing the surrounding environment. Furthermore, these metal air ducts (1000) are prone to rust and corrosion. In humid or corrosive environments, sheet metal air ducts (1000) are easily rusted and corroded, affecting their service life and performance.

[0045] To overcome the aforementioned problems, the fan ring 100 and / or panel 200 in this embodiment are made of EPP (expanded polypropylene) material. That is, both the fan ring 100 and panel 200 can be made of EPP material, or one of them can be made of EPP material. EPP foam material is lightweight, easy to handle and install, reducing construction costs. Furthermore, EPP foam material has good thermal insulation properties, effectively reducing heat exchange between the air inside the duct 1000 and the outside environment, thereby improving the energy efficiency of the ventilation system. In addition, EPP foam material has a good absorption and blocking effect on noise generated by airflow, reducing noise pollution from the ventilation system. EPP foam material also has high strength and toughness, capable of withstanding certain pressure and impact forces, thus ensuring the stability and safety of the duct 1000.

[0046] The assembly process of the air duct 1000 provided in this embodiment is as follows:

[0047] First, install the sealing strip 400 in the groove 140 of the fan ring 100. Then, use the second limiting protrusion 130 of the fan ring 100 to engage with the second limiting notch 230 of the panel 200 to achieve coaxiality of the first air hole 110 and the second air hole 220. Next, align the four first limiting notches 120 of the fan ring 100 with the four first limiting protrusions 210 of the panel 200 to align the first mounting portion 121 and the second mounting portion 211. Then, place a flat washer on the first mounting portion 121 of the fan ring 100, and finally use bolts 500 to align the flat washer and the fan ring 100 with the second mounting portion 211 and fix them with welding nuts 300. This allows for quick and convenient installation and disassembly.

[0048] In summary, the air duct 1000 includes an air ring 100 and a panel 200. The air ring 100 has a first air hole 110 and a first limiting notch 120, which is provided with a first mounting part 121. The panel 200 has a second air hole 220 and a first limiting protrusion 210, which is provided with a second mounting part 211. The first limiting protrusion 210 and the first limiting notch 120 cooperate to limit each other, so that the first mounting part 121 and the second mounting part 211 are correspondingly arranged and the second air hole 220 and the first air hole 110 are correspondingly arranged. The first mounting part 121 and the second mounting part 211 are detachably connected. By providing a first limiting notch 120 and a first limiting protrusion 210 that mates with the first limiting notch 120, the first limiting notch 120 and the first limiting protrusion 210 can quickly position and limit the air shroud 100 during installation, allowing operators to align the air shroud 100 with the mounting portion of the panel 200 for rapid installation. Furthermore, mounting portions are provided at the first limiting protrusion 210 and the first limiting notch 120, allowing for detachable connection between the two. This ensures the overall structural strength of the air duct 1000 while enhancing the stability of the connection between the air shroud 100 and the panel 200, and also enables rapid installation and disassembly.

[0049] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
