Description

Technical Field

[0001] This utility model relates to the field of duct technology for ventilation systems, and in particular to an air duct quick-dispatch system. Background Technology

[0002] As people's living standards improve, more and more buildings are equipped with central air conditioning and fresh air systems to provide a more comfortable indoor environment. Generally, central air conditioning and fresh air systems have internal power units and ventilation ducts for gas transport. During operation, these systems generate significant wind noise and vibration. Technicians typically use ventilation silencers to eliminate or reduce this noise and vibration, controlling the airflow noise and vibration generated during operation. However, due to space limitations during duct installation, modifications are often necessary. These modifications can significantly impact the reliability of subsequent use, leading to air leaks and damage. Therefore, a quick-connect duct system is needed to replace traditional duct connection methods, meeting space requirements while preventing duct damage and ensuring reliable operation. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an air duct quick-connect system to solve the problem of avoiding damage to the air duct due to space constraints during use in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] An air duct quick-connect system, comprising:

[0006] The system comprises a main duct and branch ducts. The main duct is the primary air duct and uses rigid pipes (hard pipes). The branch ducts are flexible pipes that connect to the user end. The main duct system and branch duct system are a combination of rigid and flexible pipes. All connections between the components of the main duct and the flexible pipes use socket-type interfaces.

[0007] To achieve the above technical solution, the main duct system is the primary air duct, which uses rigid ducts (hard pipes). The branch duct system is a flexible pipe system connecting to the user end. This combination of rigid and flexible pipes can accommodate system measurement errors and installation errors during the installation process through flexible elbows and end hoses, thereby improving the fault tolerance of the duct quick-fit system. All connections between the main duct components and the hoses use socket-type interfaces, which can improve the convenience of installation and facilitate subsequent installation and processing.

[0008] In one embodiment of the present invention, the main duct system includes a main duct, branch ducts, tee pipes and air valves, and the connection ports between the main duct, branch ducts, tee pipes and air valves are all socket-type connection ports.

[0009] In one embodiment of this utility model, the main air duct is a duct, which consists of an inner tube, an insulation layer, an outer jacket, and a socket joint.

[0010] To achieve the above technical solution, the outer casing of the Lemi tube is made of environmentally friendly flame-retardant blade-coated cloth, which has the effects of high strength, moisture resistance, mildew resistance, and condensation prevention. Combined with the inner tube and insulation layer, it can further improve the insulation effect of the Lemi tube. The socket interface has the characteristics of easy connection and no air leakage, which improves the sealing reliability of the Lemi tube.

[0011] In one embodiment of the present invention, multiple air distribution interfaces may be provided on the side wall of the air distribution duct. The air distribution interfaces are connected to the side wall of the air duct by a socket-type interface. A sound-absorbing flexible tube is also provided on the air distribution interface. An aluminum foil perforated inner tube is provided inside the sound-absorbing flexible tube. Sound-absorbing cotton is provided between the inner wall of the sound-absorbing flexible tube and the aluminum foil perforated inner tube.

[0012] To achieve the above technical solution, the air distribution interface can be easily connected to the air distribution duct, improving the convenience of the duct quick-match system. The micro-perforations on the wall of the aluminum foil perforated inner tube can enhance the sound absorption effect of the sound-absorbing hose. In addition, the sound-absorbing cotton placed between the inner wall of the sound-absorbing hose and the aluminum foil perforated inner tube can further improve the sound absorption effect of the sound-absorbing hose.

[0013] In one embodiment of this utility model, the tee pipe includes a T-shaped tee pipe and an angled side tee pipe, and the ports of the T-shaped tee pipe and the angled side tee pipe that connect to the outside are both socket-type interfaces.

[0014] To achieve the above technical solution, the use of T-shaped tees and angled side tees can improve the adaptability of the duct system. T-shaped tees can be used to connect where bends are needed during installation, thereby improving the stability of the duct system.

[0015] In one embodiment of the present invention, the main pipe system further includes a flexible elbow connected to the rigid pipe, and both ends of the flexible elbow are provided with socket-type interfaces.

[0016] By implementing the above technical solution, the flexible elbow can meet the usage requirements at bends. By providing socket-type interfaces at both ends of the flexible elbow, the connection convenience of the flexible elbow can be improved.

[0017] In one embodiment of the present invention, the flexible elbow comprises an inner aluminum foil tube, an outer jacket wrapping the inner aluminum foil tube, and insulation cotton disposed between the inner aluminum foil tube and the outer jacket.

[0018] The use of an inner aluminum foil tube and an outer jacket ensures that the flexible elbow has good support and flexibility, while the addition of insulation cotton can improve the insulation effect of the flexible elbow.

[0019] In one embodiment of this utility model, a loose-fitting insulation sleeve is provided at the socket connection of both the main pipe system and the branch pipe system.

[0020] The use of elastic insulation sleeves can improve the insulation stability at the connection between the main pipe system and the branch pipe system.

[0021] As described above, the air duct quick-fit system of this utility model has the following beneficial effects: the use of a combination of rigid and flexible pipes can accommodate system measurement errors and installation errors during the installation process through flexible elbows and end hoses, thereby improving the fault tolerance of the duct quick-fit system; and the use of socket-type interfaces at the connection points between the rigid pipes, the main duct, and the flexible hoses can improve the convenience of installation and facilitate subsequent installation and processing.

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Please see Figures 1 to 2 This utility model provides an air duct quick-connect system, a main duct system and a branch duct system. The main duct system is the main air duct and adopts a rigid pipe, i.e., a hard pipe. The branch duct system is a flexible pipe that connects to the user end. The main duct system and the branch duct system are a combination of flexible and rigid pipes. All connections between the components of the main duct and the flexible pipes adopt a socket-type interface.

[0028] To achieve the above technical solution, the main duct system is the primary air duct, which uses rigid ducts (hard pipes). The branch duct system is a flexible pipe system connecting to the user end. This combination of rigid and flexible pipes can accommodate system measurement errors and installation errors during the installation process through flexible elbows and end hoses, thereby improving the fault tolerance of the duct quick-fit system. All connections between the main duct components and the hoses use socket-type interfaces, which can improve the convenience of installation and facilitate subsequent installation and processing.

[0029] The main duct system includes a main duct 1, branch ducts 2, tee pipes and air valves 3. The connection ports between the main duct 1, branch ducts 2, tee pipes and air valves 3 are all socket-type connection ports. The main duct 1 is a duct with a ductwork design. The ductwork is composed of an inner tube 9, an insulation layer 10, an outer jacket 11 and a socket interface 12. Furthermore, the outer jacket 11 is an environmentally friendly flame-retardant knife-coated fabric.

[0030] The outer casing 11 of the Lemi tube is made of environmentally friendly flame-retardant blade-coated cloth, which has high strength, moisture-proof, mildew-proof and condensation-proof effects. Together with the inner tube 9 and the insulation layer 10, it can further improve the insulation effect of the Lemi tube. The socket interface 12 has the characteristics of easy connection and no air leakage, which improves the sealing reliability of the Lemi tube.

[0031] Multiple air distribution interfaces 6 can be opened on the side wall of the air distribution duct 2. The air distribution interface 6 is connected to the side wall of the air duct by a socket interface. The air distribution interface 6 is also equipped with a sound-absorbing flexible tube 5. The sound-absorbing flexible tube 5 is provided with an aluminum foil perforated inner tube. Sound-absorbing cotton is provided between the inner wall of the sound-absorbing flexible tube 5 and the aluminum foil perforated inner tube.

[0032] The air distribution interface 6 can be easily connected to the air distribution pipe 2, improving the convenience of the air duct quick-match system. The micro-perforations on the pipe wall of the aluminum foil perforated inner pipe can enhance the sound absorption effect of the sound-absorbing hose 5. In addition, the sound-absorbing cotton placed between the inner wall of the sound-absorbing hose 5 and the aluminum foil perforated inner pipe can further improve the sound absorption effect of the sound-absorbing hose 5.

[0033] The tee pipe includes a T-shaped tee pipe 8 and an angled side tee pipe 7. Both the T-shaped tee pipe 8 and the angled side tee pipe 7 have socket-type interfaces for connecting to the outside. By using the T-shaped tee pipe 8 and the angled side tee pipe 7, the adaptability of the duct system can be improved. When a bend is required during installation, the tee pipe can be used for connection, thereby improving the stability of the duct in use.

[0034] The main pipe system also includes a flexible elbow 4 connected to the rigid pipe. Both ends of the flexible elbow are equipped with socket joints. The flexible elbow 4 can meet the usage requirements at the bend. The socket joints at both ends of the flexible elbow can improve the connection convenience of the flexible elbow.

[0035] The flexible elbow 4 consists of an aluminum foil inner tube, an outer sleeve that wraps around the aluminum foil inner tube, and insulation cotton 16 placed between the aluminum foil inner tube and the outer sleeve. The aluminum foil inner tube and the mesh fabric can ensure that the flexible elbow 4 has good support and flexibility, while the insulation cotton 16 can improve the insulation effect of the flexible elbow 4.

[0036] Elastic insulation sleeves are installed at the socket connections of both the main pipe system and the branch pipe system. The installation of elastic insulation sleeves can improve the insulation stability of the connection between the main pipe system and the branch pipe system.

[0037] This utility model, by setting air valves and end tee pipes at both ends of the distribution duct, adopts a flexible and rigid pipe combination pipeline system, which can accommodate system measurement errors and installation errors during the installation process by flexible elbows and end flexible hoses, thereby improving the fault tolerance rate of the duct quick-match system. The connection between the rigid pipe and the main air duct 1 and the flexible hose all adopt socket interface connection, which can improve the convenience of installation and facilitate subsequent installation and processing.
