Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0026] Referring to 1-5, one embodiment of this utility model provides a corrosion-resistant ventilation duct structure, including a ventilation duct 1 for conveying air or gas. An air outlet 3 is fixedly connected to the bottom of the ventilation duct 1 to discharge air treated by the ventilation system to the target area, ensuring indoor air circulation and renewal. An air outlet cover 4 is provided at the bottom of the ventilation duct 1 to prevent external dust, debris, moisture, etc., from entering the duct, protecting the air filter 12 and the air outlet 3 from contamination and damage. Connecting seats 2 are fixedly connected to both sides of the ventilation duct 1, providing a structural foundation for the installation and fixing of connecting pipes 5. A connecting pipe 5 is provided inside the right-side connecting seat 2 to extend the ventilation duct 1 or change the duct's direction, ensuring that the layout of the ventilation system can adapt to different building structures and ventilation needs. The air outlet 3 has four corners in the middle... A magnetic suction plate 19 is fixedly connected to each air outlet 3 duct to fix the air filter 12. The air filter 12 is firmly attracted to the four corners inside the duct of the air outlet 3 by magnetic force. The air filter 12 is set at the bottom of the magnetic suction plate 19 to filter impurities and dust in the air and improve air quality. Limiting plates 6 are fixedly connected to the left and right sides of the air outlet 3 to limit the limiting rod 10. The limiting rod 10 is set in the middle of the limiting plate 6. The air outlet cover 4 is firmly fixed to the air outlet 3 duct by means of spring 7. The top and bottom of one side of the connecting seat 2 are provided with sliding grooves 16 to cooperate with the sliding grooves 17 on the connecting pipe 5. The top and bottom of the connecting pipe 5 are fixedly connected with sliding sliders 17 to slide inside the sliding grooves 16. The sliding sliders 17 and the sliding grooves 16 are slidably connected.

[0027] Both the top of the air outlet cover 4 and the top of the air outlet 3 have insertion holes 11 for the movement of the limiting rod 10 inside. The insertion holes 11 correspond to the positions of the limiting rod 10. The bottom left and right sides of the air outlet cover 4 have slots 9 for engaging with the limiting rod 10 to hold the air outlet cover 4 in place. The sliding groove 16 has limiting holes 18 inside, with a fixing bolt 8 threaded in the middle of the limiting hole 18 to securely fix the slider 17 of the connecting seat 2 and the connecting pipe 5 together, preventing the slider 17 from sliding in the sliding groove 16 and ensuring the connection's firmness and stability. The bottom front and rear sides of the air filter 12 are fixedly connected to fixing plates 14 for placing the push plate 15. The middle of the fixing plate 14 is slidably connected to the push plate 15, which, together with the limiting groove 13, holds the air filter 12 in place, making it more stable. The air outlet 3 has limiting grooves 13 inside on both the front and rear sides. The air filter 12 is used in conjunction with the push plate 15 in the bottom fixing plate 14 to achieve mechanical fixation of the air filter 12. The limiting groove 13 and the push plate 15 are positioned correspondingly. A spring 7 is provided in the middle of the limiting rod 10. By squeezing the spring 7 and then rotating the limiting rod 10, the limiting rod 10 is locked in the slot 9. A sealing ring 22 is provided in the middle of the connecting seat 2 to prevent gas or liquid leakage and ensure the sealing of the ventilation system. The inner wall of the ventilation pipe 1 is provided with an anti-corrosion layer 21, which uses epoxy zinc-rich primer. It has strong adhesion to metal substrates, excellent corrosion resistance, and can effectively resist the erosion of various chemical media, extending the service life of the pipe. The outer side of the ventilation pipe 1 is provided with a heat insulation layer 20, which uses rubber and plastic insulation material. It can prevent condensation caused by low pipe surface temperature, reduce the accumulation of moisture on the pipe surface, and thus reduce the risk of corrosion caused by humid environment.

[0028] Working principle: First, the connecting pipe 5 is spliced ​​according to the required length of the ventilation pipe 1. The slider 17 at the top of the connecting pipe 5 is slid into the groove 16 of the connecting seat 2, and then fixed with the fixing bolt 8 to complete the splicing of the connecting pipe 5. Then, the exhaust device at one end of the ventilation pipe 1 delivers the required exhaust air to the ventilation pipe 1 through the connecting pipe 5. The air is then filtered by the air filter 12 at the air outlet 3 at the bottom of the ventilation pipe 1 to remove impurities. The filtered air is then discharged through the air outlet cover 4, improving the air quality of the ventilation system. When the air filter 12 needs to be cleaned, the spring 7 of the limiting rod 10 is compressed by pressing it, and then the limiting rod 10 is rotated to disengage it from the slot 9. The limiting rod 10 is then... Spring 7 springs back into socket 11. Then remove air outlet cover 4. Pull the push plate 15 at the bottom of air filter 12 to remove it from the limiting groove 13. Remove air filter 12 from magnetic plate 19 for cleaning. After cleaning air filter 12, attach air filter 12 to magnetic plate 19. Push the push plate 15 at the bottom of air filter 12 to lock it in the limiting groove 13. Place air outlet cover 4 back in place and press limiting rod 10 to compress spring 7 inside limiting rod 10. Press it to a certain position and then rotate limiting rod 10 to lock it in slot 9. At the same time, spring 7 springs back without force, and limiting rod 10 is stably locked in slot 9 so that it will not move. This completes the replacement of air filter 12.
