Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile exhaust pipe provided with a heat preservation mechanism. Background Technique

[0002] The automobile exhaust pipe is a device used for exhaust emission on an automobile. Automobile exhaust emission is often accompanied by air pollution and noise pollution. With the development of the economy, the per capita automobile ownership is increasing day by day. Automobile exhaust emission has become one of the main sources of air pollution. How to reduce the emission of polluting particulate matter in automobile exhaust has become an urgent problem to be solved. In addition, the silencing function of traditional automobile exhaust pipes is mostly realized by installing a silencer in the exhaust pipe body. For automobiles with a large exhaust volume, there is still a large amount of noise when the exhaust gas passes through the exhaust pipe body and then is discharged through the exhaust pipe.

[0003] When the existing automobile exhaust pipe is in use as a whole, during the process of discharging automobile exhaust, the exhaust pipe body is often mixed with water vapor. In cold regions, when the water vapor is discharged, it will be liquefied by the cold to form water droplets. Over time, there will be liquid water in the exhaust pipe body. When the temperature is relatively low, the water in the exhaust pipe body will freeze, and ultimately it may cause the exhaust pipe body to be blocked. The overall process in actual use often has certain limitations, and the overall use effect is poor. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automobile exhaust pipe provided with a heat preservation mechanism, so as to solve the problem that when the existing automobile exhaust pipe is in use as a whole, during the process of discharging automobile exhaust, the exhaust pipe body is often mixed with water vapor. In cold regions, when the water vapor is discharged, it will be liquefied by the cold to form water droplets. Over time, there will be liquid water in the exhaust pipe body. When the temperature is relatively low, the water in the exhaust pipe body will freeze, and ultimately it may cause the exhaust pipe body to be blocked. The overall process in actual use often has certain limitations, and the overall use effect is poor as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an automobile exhaust pipe provided with a heat preservation mechanism, including an automobile exhaust main pipe, and positioning and mounting blocks are symmetrically installed on the outer surface of the top of the automobile exhaust main pipe near the middle position; a tail gas emission guiding mechanism is arranged on one side of the automobile exhaust main pipe near the exhaust output end; a heating and heat preservation mechanism, and the heating and heat preservation mechanism is arranged outside the automobile exhaust main pipe; the heating and heat preservation mechanism includes a spring heating pipe, a heating controller, a heat insulation and preservation layer, and a metal protection sleeve.

[0006] Preferably, the tail gas emission guiding mechanism includes a solenoid valve I, an exhaust branch pipe, and a solenoid valve II, and the exhaust branch pipe is longitudinally penetrated and installed outside the top side of the automobile exhaust main pipe near the output end;

[0007] Adopting the above technical solution enables the whole device to exhaust through the exhaust branch pipe by controlling the closing of the first solenoid valve when in use, so that the whole device can exhaust normally at a relatively deep wading depth.

[0008] Preferably, a second solenoid valve is installed through and communicated inside the side of the exhaust branch pipe close to the vehicle exhaust main pipe. Exhaust connectors II and I are respectively arranged at the output ends of the top of the exhaust branch pipe and the output end of the vehicle exhaust main pipe.

[0009] Adopting the above technical solution enables the whole device to close the exhaust branch pipe through the setting of the second solenoid valve when in use, so that the whole device can operate stably during normal use.

[0010] Preferably, a first solenoid valve is installed through and communicated inside the side of the vehicle exhaust main pipe between the exhaust connector I and the exhaust branch pipe. Threaded sealing joints are installed at one ends of the exhaust connector I and the exhaust connector II close to the vehicle exhaust main pipe and the exhaust branch pipe, and one ends of the threaded sealing joints are threadedly and rotatably installed inside one sides of the exhaust connector I and the exhaust branch pipe. The output end of the exhaust connector I is integrally inclined.

[0011] Adopting the above technical solution enables the whole device to prevent water from remaining inside the output end of the vehicle exhaust main pipe after wading through the water due to the inclined installation of the exhaust connector I when in use.

[0012] Preferably, the spring heating tube is installed around and embedded on the inner wall of the vehicle exhaust main pipe. A heating controller is fixedly installed on the outer surface of one side of the vehicle exhaust main pipe, and the heating controller is electrically controlled and connected to the spring heating tube.

[0013] Adopting the above technical solution enables the whole device to be evenly heated and insulated through the setting of the spring heating tube when in use, so that the whole device is not easy to condense and the exhaust use effect of the whole device is ensured.

[0014] Preferably, a heat insulation and heat preservation layer is evenly sleeved and fitted on the outer surface of the vehicle exhaust main pipe. A metal protective sleeve is fixedly sleeved and wrapped on the outer surface of the vehicle exhaust main pipe where the heat insulation and heat preservation layer is located.

[0015] Adopting the above technical solution enables the whole device to protect the internal heat insulation and heat preservation layer through the installation of the metal protective sleeve when in use, so as to extend the overall service life.

[0016] Compared with the prior art, the beneficial effect of the present utility model is that the vehicle exhaust pipe provided with a heat preservation mechanism:

[0017] 1. During the actual use of the entire device, a spring heating tube is installed in an embedded and circumferential manner on the inner wall of the main exhaust pipe, so that when the entire device is used in cold regions, the temperature inside the exhaust pipe can be guaranteed. Therefore, when the temperature is relatively low during actual use, the water in the exhaust pipe will not freeze, thereby reducing the possibility of condensation and blockage inside the exhaust pipe, playing a certain role in heating and protection, and the overall practicality is strong;

[0018] 2. During the actual use of the entire device, an exhaust branch pipe is penetrated and conducted on the outer surface of one side of the top of the main exhaust pipe. At the same time, with the installation of solenoid valve 1 and solenoid valve 2, when the entire device is used in places with relatively deep water wading, the gas can be discharged from the exhaust branch pipe, blocking the exhaust port of the main exhaust pipe of the vehicle to prevent backflow and water ingress, thereby ensuring the overall operation stability and preventing the vehicle from stalling;

[0019] 3. During the actual use of the entire device, during the use of the entire vehicle exhaust pipe, an insulating and heat-preserving layer is installed on the outer surface, so that the overall heating and heat-preserving effect is better. At the same time, a metal protective sleeve is arranged outside the insulating and heat-preserving layer, thereby extending the service life of the overall heat-preserving mechanism, playing a certain role in protection and isolation, and making the overall use effect better.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution: an automobile exhaust pipe provided with a heat preservation mechanism, including an automobile exhaust main pipe 1, and positioning and mounting blocks 2 are symmetrically installed on the outer surface of the top of the automobile exhaust main pipe 1 near the middle position; a heating and heat preservation mechanism 4 is arranged outside the automobile exhaust main pipe 1, and the heating and heat preservation mechanism 4 includes a spring heating pipe 401, a heating controller 402, a heat insulation and preservation layer 403, and a metal protection sleeve 404;

[0027] In this embodiment, the automobile exhaust pipe provided with a heat preservation mechanism mainly includes an automobile exhaust main pipe 1, positioning and mounting blocks 2, and a heating and heat preservation mechanism 4. When the whole automobile exhaust pipe is in use, by arranging heat preservation and heating structures outside and inside the exhaust pipe, the temperature inside the exhaust pipe can be guaranteed when the whole is used in cold regions. Therefore, when the temperature is relatively low during actual use, the water in the exhaust pipe will not freeze, thereby reducing the possibility of condensation and blockage inside the exhaust pipe, playing a certain role in heating and protection, and the overall practicality is strong.

[0028] In some embodiments, a tail gas emission guiding mechanism 3 is arranged on one side of the automobile exhaust main pipe 1 close to the exhaust output end. The tail gas emission guiding mechanism 3 includes a solenoid valve 1 301, an exhaust branch pipe 302, and a solenoid valve 2 303. The exhaust branch pipe 302 is longitudinally penetrated and installed through the outside of the top side of the automobile exhaust main pipe 1 close to the output end. When the whole exhaust pipe is in use, when the whole needs to pass through a road surface with deep water, at this time, the solenoid valve 1 301 is controlled to close, and at the same time, the solenoid valve 2 303 is controlled to open, so that the exhaust output end of the whole is transferred from the automobile exhaust main pipe 1 to the exhaust branch pipe 302 located at a high position, so that when wading, water will not flow back, causing the engine to stall, thereby ensuring the overall operation stability. The overall operation is simple, the use is convenient, and the overall use effect is good.

[0029] In some embodiments, a second solenoid valve 303 is installed inside the exhaust manifold 302 near the side of the main automotive exhaust pipe 1 in a penetrating and conducting manner. Exhaust connectors II 6 and I 5 are respectively provided at the output ends of the top of the exhaust manifold 302 and the output end of the main automotive exhaust pipe 1. When the entire exhaust pipe is in use, the exhaust connectors II 6 and I 5 are respectively installed outside the exhaust manifold 302 and the main automotive exhaust pipe 1 through threaded sealing connectors 7, so that the overall use effect is better. At the same time, when the whole is disassembled, assembled and replaced later, the overall use effect is better, making the whole more convenient to use.

[0030] In some embodiments, a first solenoid valve 301 is installed inside the main automotive exhaust pipe 1 near the side between the exhaust connector I 5 and the exhaust manifold 302 in a penetrating and conducting manner. Threaded sealing connectors 7 are installed at one ends of the exhaust connector I 5 and the exhaust connector II 6 close to the main automotive exhaust pipe 1 and the exhaust manifold 302, and one ends of the threaded sealing connectors 7 are threadedly and rotatably installed inside one sides of the exhaust connector I 5 and the exhaust manifold 302. The output end of the exhaust connector I 5 is integrally inclined. When the entire exhaust pipe is in use, by setting the exhaust connector I 5 to be inclined, water will not remain inside the output end of the main automotive exhaust pipe 1 when wading, and can be effectively discharged, so that the overall use effect is better and the overall use convenience is better.

[0031] In some embodiments, a spring heating tube 401 is installed around and embedded in the inner wall of the main automotive exhaust pipe 1. A heating controller 402 is fixedly installed on the outer surface of one side of the main automotive exhaust pipe 1, and the heating controller 402 is electrically connected to the spring heating tube 401 for control. When the entire exhaust pipe is in use, the spring heating tube 401 is evenly embedded and surrounded inside the pipe wall, and at the same time, the existing heating controller 402 is used to control the start, stop and heating temperature of the spring heating tube 401, so that the overall heating and heat preservation effect is better, the whole is not easy to condense and block, so that the overall use effect is better and the use is more convenient.

[0032] In some embodiments, a heat insulation and heat preservation layer 403 is evenly sleeved and fitted on the outer surface of the main automotive exhaust pipe 1. A metal protective sleeve 404 is fixedly sleeved and wrapped on the outer surface of the main automotive exhaust pipe 1 where the heat insulation and heat preservation layer 403 is located. During the use process of the entire exhaust pipe, by setting the heat insulation and heat preservation layer 403 on the outer surface of the main automotive exhaust pipe 1, the overall heat preservation and cold resistance effect is better, ensuring the overall use effect. At the same time, the heat insulation and heat preservation layer 403 here is made of existing heat-resistant and heat-insulating materials. At the same time, a metal protective sleeve 404 is sleeved on the outer surface of the heat insulation and heat preservation layer 403, so that when the whole is in use, the heat insulation and heat preservation layer 403 can be heat-preserved, thereby prolonging the overall service life and making the overall use effect better.
