Description

Technical Field

[0001] This utility model relates to the field of automotive exhaust pipe technology, specifically to an anti-clogging automotive exhaust pipe. Background Technology

[0002] The exhaust pipe is an important component of a car's exhaust system. It guides the exhaust gases emitted by the engine to the rear of the vehicle, reducing pollution to the passenger compartment. The main function of the exhaust pipe is to safely and effectively expel the exhaust gases produced by engine combustion from the vehicle. A well-designed exhaust pipe system can improve engine performance, power output, and fuel efficiency. Proper maintenance and inspection of the exhaust pipe can improve vehicle performance and extend its service life.

[0003] A blocked exhaust pipe increases exhaust pressure, preventing exhaust gases from being effectively expelled. This leads to increased internal engine pressure, affecting engine power and acceleration performance. Poor exhaust also forces the engine to consume more fuel to overcome the additional exhaust resistance, increasing fuel consumption. Reduced engine output power and decreased vehicle acceleration can result in insufficient power or sluggish driving. Furthermore, a blocked exhaust system can prevent timely exhaust, potentially causing engine overheating. Prolonged high-temperature operation can damage internal engine components. In short, a blocked exhaust pipe can cause significant damage to a car.

[0004] Existing car exhaust pipes may become clogged during use. Foreign objects, such as branches or plastic strips, may enter the exhaust pipe, causing blockage. Small animals such as rats or weasels may also crawl into the exhaust pipe, causing blockage. Alternatively, some people may maliciously block the exhaust pipe with materials. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an anti-clogging automobile exhaust pipe, which has the following beneficial effects:

[0017] 1. This anti-clogging car exhaust pipe is equipped with a blockage-clearing device and matching structure, which allows the pusher plate inside the exhaust pipe to move from the inside to the outside, thereby clearing away the blocking debris. The structure requires little space, is stable and sturdy, and is simple and convenient to use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Please see Figure 1-6 This utility model provides a technical solution:

[0029] A clog-resistant automotive exhaust pipe includes an exhaust pipe 1 with multiple sets of strip-shaped cuts 5 at its end. A blockage-clearing device 2 is installed on the exhaust pipe 1 corresponding to each of the strip-shaped cuts 5. A moving device 3 and a limiting device 4 are sequentially fitted onto the side of the exhaust pipe 1 adjacent to the blockage-clearing device 2. The blockage-clearing device 2 is used to clear blockages when they occur. The moving device 3 assists the blockage-clearing device 2 in moving on the exhaust pipe 1. The limiting device 4 assists in cooperating with the moving device 3.

[0030] Furthermore, anti-crack rings 6 are machined at the ends of the multiple sets of strip-shaped cuts 5 on the exhaust pipe 1. The anti-crack rings 6 are used to prevent the cracks in the multiple sets of strip-shaped cuts 5 from extending and causing the exhaust pipe 1 to break and be damaged.

[0031] Furthermore, the unblocking device 2 includes a collar 7, connecting blocks 8, and unblocking pushers 9. The collar 7 is fitted onto the exhaust pipe 1, and the collar 7 is connected to connecting blocks 8 corresponding to multiple sets of strip-shaped cuts 5. The unblocking pushers 9 are located at the center of the multiple sets of connecting blocks 8. The unblocking pushers 9 directly act on the blockage and push it to the opening of the exhaust pipe 1 for discharge. The unblocking device 2 is used to connect with the moving device 3 to drive the unblocking pushers 9 to move. The multiple sets of connecting blocks 8 are used to prevent the unblocking device 2 from rotating coaxially with respect to the exhaust pipe 1.

[0032] Furthermore, the collar 7 has a threaded interface 10, and the unblocking pusher 9 has multiple sets of vent holes 11. The vent holes 11 are used for the passage of vehicle exhaust gas.

[0033] Furthermore, the moving device 3 includes a threaded cylinder 12, a rotating ring 13, a front seal 14, and a rear seal 15. The threaded cylinder 12 has external threads and is fitted onto the exhaust pipe 1. The front seal 14 is welded to the end of the threaded cylinder 12 near the collar 7, and the rear seal 15 is welded to the end of the threaded cylinder 12 away from the unblocking device 2. The rotating ring 13 is threadedly connected to the threaded cylinder 12. The external threads on the threaded cylinder 12 engage with the rotating ring 13. If the rotating ring 13 rotates, it can drive the threaded cylinder 12 to rotate or move in depth / contraction. The front seal 14 is connected to the collar 7, so the threaded cylinder 12 cannot rotate because the collar 7 cannot rotate. This allows the threaded cylinder 12 to move back and forth relative to the rotating ring 13. In other words, rotating the rotating ring 13 can drive the unblocking device 2 to move back and forth.

[0034] Furthermore, a bottle-shaped opening 16 corresponding to the threaded interface 10 is welded onto the front seal 14, and the bottle-shaped opening 16 is threadedly connected to the threaded interface 10. The thread direction on the bottle-shaped opening 16 is consistent with the thread direction of the threaded cylinder 12, so that if the bottle-shaped opening 16 is rotated to a deeper position after being connected to the threaded interface 10, the bottle-shaped opening 16 and the threaded interface 10 will not disengage. Whether they disengage when rotated in the opposite direction during contraction does not affect the use.

[0035] Furthermore, the limiting device 4 includes a rotating cylinder 17 and a limiting ring 18. The rotating cylinder 17 is sleeved on the threaded cylinder 12 and welded to the rotating ring 13. The limiting ring 18 is sleeved on the exhaust pipe 1 and welded to the exhaust pipe 1. The limiting ring 18 has a recessed groove 19, and the rotating cylinder 17 has a corresponding male ring 20, which is slidably engaged within the recessed groove 19. The limiting device 4 is used to limit the relative position of the rotating ring 13 and the exhaust pipe 1. Determining the position of the rotating ring 13 and the exhaust pipe 1 allows the unblocking device 2 to move back and forth relative to the exhaust pipe 1 during operation. The outer surface of the rotating ring 13 can be machined into a gear shape, which, when combined with the motor gear, enables automatic operation. Machining an anti-slip shape facilitates operation and prevents slippage during rotation.

[0036] Working principle: When using this device to clear blockages, it is not necessary to disassemble the exhaust pipe. The operator can use tools or directly rotate the rotating ring 13. The rotation of the rotating ring 13 will cooperate with the threaded cylinder 12, causing the threaded cylinder 12 to move away from the end of the limiting device 4. The threaded cylinder 12 will push the unblocking device 2 to move. When the unblocking device 2 moves, the unblocking pusher 9 on the unblocking device 2 will move outward from inside the exhaust pipe 1, pushing the blockage out of the exhaust pipe 1 to clear it.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
