The movable rod 6 forms an elastic telescopic structure between the internal spring 7 and the interior of the protective sleeve 4, and the outer end of the movable rod 6 and the main airbag 8 fit each other. The main airbag 8 is connected to the closed airbag 10 through the air delivery pipe 9, and the closed airbag 10 is set as an annular structure, and the upper end of the closed airbag 10 and the lower end of the abutment rod 11 are fitted together. The fitting surface between the dark groove 12 and the inner end of the horizontal rod 13 is set as a hypotenuse, and the outer end of the horizontal rod 13 and the slider 14 are movably connected, and the slider 14 and the warning rod 15 are slidably connected. The warning rod 15 forms a rotating structure between the central axis 16 and the side of the protective sleeve 4, and the inner side of the upper end of the warning rod 15 and the outer end of the piston rod 18 are fitted together. The liquid level of the phenolphthalein reagent inside the accommodating chamber 19 is lower than the drain port 22, and the inner wall of the accommodating chamber 19 and the inner end outer wall of the piston rod 18 are fitted together. The sodium balls 21 are evenly distributed inside the limiting cylinder 20, and the limiting cylinder 20 is set as a transparent material. The middle part of the lower end of the water storage bag 24 and the upper end of the resistance rod 11 fit each other, and the resistance rod 11 is set as a spike-shaped structure, and the resistance rod 11 forms an elastic telescopic structure through the adjustment spring 23 and the limiting tube 20.

[0047] like Figure 1-5As shown, when the fresh air system device 1 is in use and a leak occurs at the connection between the docking pipe 2 and the delivery pipe 5, the amount of gas inside the protective sleeve 4 increases. At this time, the increase in gas can push the movable rod 6 to move, and the main air bag 8 can be squeezed by the movement of the movable rod 6. When the main air bag 8 is pressurized, the internal gas enters the interior of the closed air bag 10 through the air delivery pipe 9. The expansion of the closed air bag 10 after inflation can temporarily wrap and seal the connection between the docking pipe 2 and the delivery pipe 5. At the same time, when the closed air bag 10 is inflated and expanded, the resistance rod 11 can be moved. The movement of the resistance rod 11 can squeeze and push the horizontal rod 13 through the hidden groove 12 thereon. When the horizontal rod 13 moves to the outside of the protective sleeve 4, the slider 14 at the end can move inside the warning rod 15 and cause the warning rod 15 to rotate. The change in position after the warning rod 15 rotates can give a reminder to the people around. After the touch rod 11 moves upward, the spike-like structure at its upper end can be used to pierce the water storage bag 24. At this time, the water source inside the water storage bag 24 flows outward to the inside of the limiting cylinder 20 and contacts with the sodium ball 21. A violent reaction can occur through the contact between the water source and the sodium ball 21. The chemical reaction equation is "2Na+2H2O=2NaOH+H2↑". A "hissing" sound is emitted during the reaction, and the sound is amplified by the speaker on the side of the limiting cylinder 20, so as to further remind the surrounding people. At the same time, when the warning rod 15 is rotated, it can squeeze the piston rod 18, and the piston rod 18 can move toward the inside of the accommodating chamber 19 after squeezing. The movement of the piston rod 18 can squeeze the phenolphthalein reagent inside the accommodating chamber 19 through the discharge port 22 onto the solution after the sodium ball 21 and the water source react. The phenolphthalein reagent turns red after contacting the alkaline solution, so that it is convenient for outsiders to judge whether there is a leakage by observing the color of the solution inside the limiting cylinder 20.

[0048] Working principle: When using the leakage self-alarm intelligent fresh air system, first Figure 1-8As shown, when the fresh air system is used, the infrared receiving module or the voice information receiving module recognizes the information through an external remote control or voice control, and transmits the signal to the central processor, thereby controlling the operation of the fresh air system device 1 to circulate the air in the room. At the same time, when the fresh air system device 1 is running, the PM2.5 detection sensor, the formaldehyde concentration detection sensor, the air humidity detection sensor and the air temperature detection sensor in the detection module are used to monitor the air quality in the room in real time, and the control module is used to control the air volume regulating valve to adjust the overall air volume in time. At the same time, the fresh air purifier, the refrigerator or the heater are used to purify the air in the room, and the temperature in the room is adjusted according to actual needs. When the fresh air system device 1 is in use, if the connection between the docking pipe 2 and the delivery pipe 5 leaks, the main air bag 8 can be squeezed by moving the movable rod 6, and the internal gas can enter the inside of the closed air bag 10. The connection between the docking pipe 2 and the delivery pipe 5 can be temporarily wrapped and sealed by the expansion of the closed air bag 10. At the same time, when the closed air bag 10 is inflated and expanded, it can resist the rod 1 1 is moved, and the movement of the resistance rod 11 can squeeze and push the horizontal rod 13 through the hidden groove 12 thereon. When the horizontal rod 13 moves to the outside of the protective sleeve 4, the slider 14 at the end can move inside the warning rod 15, and the warning rod 15 can be rotated. The change in position after the warning rod 15 rotates can give a reminder to the people around. The upper end of the resistance rod 11 is used to pierce the water storage bag 24, so that the water source flows outward to the inside of the limit tube 20 and contacts with the sodium ball 21. The touch can cause a violent reaction, and a "hissing" sound is emitted during the reaction. The sound is amplified by the speaker on the side of the limit cylinder 20, so as to further remind the people around. The piston rod 18 can move toward the inside of the accommodating chamber 19 after being squeezed. The movement of the piston rod 18 can squeeze the phenolphthalein reagent inside the accommodating chamber 19 through the discharge port 22 onto the solution after the sodium ball 21 and the water source react. The phenolphthalein reagent turns red after contacting the alkaline solution, so that it is convenient for outsiders to judge whether there is a leakage by observing the color of the solution inside the limit cylinder 20.
