[0024] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments;

[0025] Example 1:

[0026] This application provides a novel composite material sterilization and deodorization ventilation duct, including a duct 1; a connecting flange 101 is installed at one end of the duct 1, a reinforcing mechanism 7 is provided on the inner wall of the duct 1, a sterilization layer 5 is provided on the inner wall of the reinforcing mechanism 7, an outer protective layer 4 is provided on the inner wall of the sterilization layer 5, a structural layer 3 is provided on the inner wall of the outer protective layer 4, and an inner lining layer 2 is provided on the inner wall of the structural layer 3.

[0027] The reinforcement mechanism 7 includes a metal mesh 701 and a reinforcing fiber layer 702. The inner wall of the pipe 1 is provided with a metal mesh 701, and the inner wall of the metal mesh 701 is provided with a reinforcing fiber layer 702.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inner lining layer 2 is made of a special resin material with antibacterial function, containing surface felt and chopped strand mat, which effectively inhibits bacterial growth. The structural layer 3 is composed of medium-alkali fiber winding yarn, curing agent, and accelerator, which has high strength and toughness, ensuring the stability of pipe 1 under negative pressure environment. The outer protective layer 4 is made of corrosion-resistant and wear-resistant resin material, protecting the internal structure of pipe 1 from the influence of the external environment. The sterilization layer 5 is an active sterilization layer containing antibacterial components such as nano silver ions, which can continuously release antibacterial substances to kill bacteria and viruses in pipe 1. The connecting flange 101 can easily connect pipe 1 for use. The reinforcement mechanism 7 can improve the performance of pipe 1. Impact resistance and pressure bearing capacity are improved by adding a metal mesh 701 and a reinforcing fiber layer 702 inside the pipe 1. The metal mesh 701 can improve the load-bearing capacity and stability of the structure and prevent the structure from being damaged by external forces. The reinforcing fiber layer 702 is composed of fiber and resin materials. This composite laminate structure has excellent mechanical properties, such as high strength, high modulus, and high toughness. The fiber mainly bears the load in the composite material and forms an integral structure through close bonding with the resin matrix, which together improves the mechanical properties of the material. The impact resistance and pressure bearing capacity of the pipe 1 can be improved by adding a metal mesh 701 and a reinforcing fiber layer 702.

[0029] Furthermore, the outer surface of the pipe 1 is provided with a protective layer 6, and the outer surface of the protective layer 6 is provided with a reinforcing ring 601;

[0030] Specifically, such as Figure 1 and Figure 2 As shown, in order to improve the protection of pipe 1, the protective layer 6 is made of wear-resistant and weather-resistant material, which can protect pipe 1 from physical and chemical damage, while the reinforcing ring 601 can improve the strength of pipe 1.

[0031] Furthermore, a fixing frame 8 is installed on the outside of the connecting flange 101, and an airbag 801 is provided inside the fixing frame 8;

[0032] Furthermore, an outer ring 802 is installed on the outside of the fixed frame 8, and a fixing bolt 803 is rotatably connected inside the outer ring 802. One end of the fixing bolt 803 is connected to the fixed frame 8.

[0033] Specifically, such as Figure 2As shown, in order to detect the connectivity of pipe 1, two sets of fixing frames 8 are respectively located on the outside of the connecting flange 101 and the connecting pipe. By rotating the fixing bolt 803, the fixing bolt 803 moves inside the outer ring 802 through the thread structure, so that the fixing frame 8 fits against the outside of the connecting flange 101. When a leak occurs at the connection position of pipe 1, the air bag 801 will inflate, which makes it easier for personnel to detect and repair in time.

[0034] Furthermore, the outer surface of pipe 1 is provided with a corrosion-resistant coating 9;

[0035] Specifically, such as Figure 1 and Figure 3 As shown, in order to extend the service life of pipe 1, a corrosion-resistant coating 9 is applied to the outer surface of pipe 1. The corrosion-resistant coating 9 can slow down the aging process of the material, thereby extending the service life of pipe 1.

[0036] Furthermore, the inner wall of the inner lining layer 2 is provided with a sterilization rod 501;

[0037] Specifically, such as Figure 1 As shown, in order to improve the sterilization effect inside the pipe 1, multiple sets of sterilization rods 501 are set on the inner wall of the sterilization layer 5. The sterilization rods 501 can reduce the airflow speed, so that the sterilization rods 501 and the sterilization layer 5 can fully sterilize the air.

[0038] Working principle: Pipe 1 is connected and fixed by connecting flange 101. When air passes through the inside of pipe 1, the inner lining layer 2 can effectively inhibit bacterial growth. The structural layer 3 can provide stability of pipe 1 under negative pressure environment. The outer protective layer 4 can protect the internal structure of pipe 1 from the influence of external environment. The sterilization layer 5 and sterilization rod 501 can kill bacteria and viruses in pipe 1. The metal mesh 701 and reinforcing fiber layer 702 can improve the impact resistance and pressure bearing capacity of pipe 1. The corrosion resistant coating 9 can delay the material aging process. Finally, the protective layer 6 and reinforcing ring 601 can improve the strength and wear resistance of pipe 1.

[0039] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
