The inner wall of the annular slot 9 is fitted with a washer 10, which is a rubber ring and fits into the insertion tube 5. The washer 10 seals the insertion of the insertion tube 5 into the inner wall of the annular slot 9, preventing gaps from forming and ensuring the accuracy of the guardrail 6 in blocking the through-wall pipe 1. The surface of the through-wall pipe 1 is rotatably connected to a rotating ring shell 11 and a rotating ring plate 12. The inner wall of the rotating ring shell 11 and the through-wall pipe 1 are fixedly connected to a coil spring 13. Hook 14 and hook 2 15 are welded to the surfaces of the rotating ring plate 12 and the insertion tube 5, respectively.

[0024] Example 2:

[0025] Figure 1-5 This invention illustrates a non-powered ventilation and purification device according to an embodiment of the present invention, comprising a through-wall pipe 1; an elastic push-button switch 2 is installed on the inner wall of the through-wall pipe 1, a sealing plate 3 is installed on the surface of the elastic push-button switch 2, a purification filter plate 4 is fixedly connected to the inner wall of the through-wall pipe 1, an insert pipe 5 is inserted into the surface of the through-wall pipe 1, a protective railing 6 is fixedly connected to the bottom end of the insert pipe 5, a sleeve block 7 is welded to the surface of the through-wall pipe 1, and an L-shaped insert rod 8 is welded to the surface of the insert pipe 5. The surface of tube 1 is provided with an annular slot 9 that is compatible with the insertion tube 5. The surface of the through-wall tube 1 is rotatably connected with a rotating ring shell 11 and a rotating ring plate 12. The inner wall of the rotating ring shell 11 and the through-wall tube 1 are fixedly connected with a coil spring 13. Hook 14 and hook 2 15 are welded to the surfaces of the rotating ring plate 12 and the insertion tube 5 respectively. The diameter of the sealing plate 3 is compatible with the outer diameter of the through-wall tube 1. The ends of hook 14 and hook 2 15 are both provided with bevels, and hook 14 and hook 2 15 are hooked together.

[0026] Working Principle: In use, the user inserts the through-wall pipe 1 through a wall hole, then fills and seals the gap between the through-wall pipe 1 and the inner wall of the wall hole with silicone foam. Next, pressing the sealing plate 3 opens the gap between the sealing plate 3 and the through-wall pipe 1 under the elastic force of the elastic push switch 2. This allows outside air to enter the insertion pipe 5 after being filtered by the protective railing plate 6. The air is then filtered and purified by the purification filter plate 4 as it passes through the through-wall pipe 1 and enters the room. Rotating the rotating ring shell 11 causes the rotating ring plate 12 to rotate on the surface of the through-wall pipe 1. At this time, the rotating ring shell 11 causes the coil spring 13 to deform. Then, insert the insertion tube 5 into the annular slot 9 on the surface of the through-wall pipe 1, and simultaneously insert and fix the L-shaped insertion rod 8 into the sleeve block 7. Then, release the rotating ring shell 11, so that the rebound force of the coil spring 13 drives the rotating ring shell 11 and the rotating ring plate 12 to rotate. Then, the rotating ring plate 12 drives the hook one 14 and the hook two 15 to engage, so that the insertion tube 5 can drive the protective guardrail 6 to be fixed to the through-wall pipe 1. Similarly, if it is necessary to disassemble and clean the protective guardrail 6, refer to the above steps. This realizes the convenient disassembly and assembly between the protective guardrail and the through-wall pipe, which facilitates the disassembly and cleaning of the protective guardrail during subsequent use, thereby improving the smoothness of the ventilation pipe during use.

[0027] In summary, this non-powered ventilation and purification device, by inserting the insertion tube 5 into the wall-penetrating pipe 1, at which point the L-shaped insertion rod 8 is inserted and fixed into the sleeve block 7, and then the rebound force of the coil spring 13 drives the rotating ring shell 11 and the rotating ring plate 12 to rotate. Subsequently, the rotating ring plate 12 drives the hook one 14 and the hook two 15 to be engaged, thereby achieving convenient disassembly and assembly between the protective baffle and the wall-penetrating pipe. This facilitates the disassembly and cleaning of the protective baffle during subsequent use, thereby improving the smoothness of the ventilation duct during use.
