Description
Technical Field
[0001] The utility model relates to the technical field of motorboat components, in particular to an exhaust gas path structure and a motorboat adopting the structure. Background Art
[0002] As is known, the exhaust system is an important part of the engine, and its function is to reduce the noise and temperature of the engine exhaust, thereby reducing the impact of the engine exhaust on the surrounding environment;
[0003] In the existing exhaust gas path structures of motorboats, most of the overall structures are relatively simple. When the motorboat is started, the end of the exhaust structure is often inserted into the water. Therefore, when the motorboat is running, the motorboat is often prone to choking on water and stalling, which will affect the service life of the motorboat. Utility Model Content
[0004] The purpose of the utility model is to overcome the problem that in the prior art, the exhaust gas path structure of a motorboat is mostly simple in overall structure, and when the motorboat is started, the end of the exhaust structure is often inserted into the water. Therefore, when the motorboat is running, the motorboat is often prone to choking on water and stalling. An exhaust gas path structure and a motorboat using the structure are provided. The exhaust gas path structure is designed for the overall structure so that when it is applied to a motorboat, when the exhaust section is inserted into the water, water is not easy to flow back from the exhaust section into the exhaust pipe of the motorboat. This can avoid the motorboat choking on water and stalling, thereby ensuring the use effect and service life of the motorboat.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] The utility model discloses an exhaust gas path structure and a motorboat adopting the structure, comprising an exhaust gas path structure adopting a three-section structure, namely an air intake section, a main body section and an exhaust section, wherein the air intake section and the exhaust section are respectively located at two ends of the main body section; an inverted U-shaped structure is formed between the air intake section and the main body section, an L-shaped structure is formed between the exhaust section and the main body section, and the directions of the air intake section and the exhaust section are vertical. Such a structural arrangement enables the exhaust gas path structure to be applied to a motorboat, and when the exhaust section is inserted into water, water is not easy to flow back from the exhaust section into the exhaust pipe of the motorboat, so that the motorboat can be prevented from being choked by water and stalled, thereby ensuring the use effect and service life of the motorboat.
[0007] Preferably, there is an angle between the center line of the main section and the extended line of the center line of the air intake section, which is set to ∠β; there is an angle between the center line of the main section and the straight line perpendicular to the center line of the exhaust section, which is set to ∠α. Then, ∠α>90°>∠β. In this way, when the exhaust section is inserted into the water and water splashes upward from the exhaust section, the splashed water can quickly fall back into the exhaust section due to the action of the angle, thereby further avoiding water backflow.
[0008] Preferably, a docking port is provided at the port position of the air intake section, and the outer diameter of the docking port is smaller than the outer diameter of the air intake section, so that the port of the air intake section forms a step-like structure with a snap-fit effect. Such a structural arrangement makes it more convenient to install the air intake section and the exhaust pipe of the motorboat.
[0009] Preferably, at least one positioning edge is provided at the port position of the air intake section, and the positioning edge is arranged along the length direction of the air intake section. Such a structural arrangement ensures that the air intake section and the exhaust pipe of the motorboat will not be misaligned when installed, and the entire device will not rotate abnormally after installation, so that the exhaust section will not tilt.
[0010] Preferably, an outer wall of the air intake section is further provided with a hoop assembly groove, and the hoop assembly groove is provided along the circumference of the air intake section to assist in fixing the air intake section.
[0011] Another object of the present application is to provide an application of any of the above-mentioned integrated consoles in a motorboat. Specifically, the end of the air intake section is connected to the exhaust pipe port of the motorboat.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] The exhaust gas path structure is designed for its overall structure so that when it is used on a motorboat, when the exhaust section is inserted into the water, water is not likely to flow back from the exhaust section into the exhaust pipe of the motorboat, thus preventing the motorboat from choking on water and stalling, thereby ensuring the use effect and service life of the motorboat, and the device is quick and easy to install and disassemble.

[0018] The following is combined with Figure 1 -Attached Figure 3 , further illustrating the specific implementation of the exhaust gas path structure of the utility model and the motorboat using the structure, which overcomes the problem that most of the exhaust gas path structures of motorboats in the prior art have a relatively simple overall structure, and when the motorboat is started, the end of the exhaust structure often inserts into the water. Therefore, when the motorboat is running, it is often easy for the motorboat to choke on water and stall. The exhaust gas path structure is designed for the overall structure so that when it is applied to the motorboat, when the exhaust section is inserted into the water, water is not easy to flow back from the exhaust section into the exhaust pipe of the motorboat, so that the motorboat can avoid choking on water and stalling, and ensure the use effect and service life of the motorboat. The exhaust gas path structure of the utility model and the motorboat using the structure are not limited to the description of the following embodiments.

[0021] Furthermore, there is an angle between the center line of the main section 2 and the extended line of the center line of the air intake section 1, which is set to ∠β, and there is an angle between the center line of the main section 2 and the straight line perpendicular to the center line of the exhaust section 3, which is set to ∠α. Then, ∠α>90°>∠β. In this way, when the exhaust section 3 is inserted into the water and water splashes upward from the exhaust section 3, the splashed water can quickly fall back into the exhaust section 3 under the action of the angle, further avoiding water backflow.
[0022] By adopting the above technical solution:
[0023] When the exhaust gas path structure is applied to a motorboat, when the exhaust section 3 is inserted into the water, water is not easy to flow back from the exhaust section 3 into the exhaust pipe of the motorboat, which can avoid the motorboat being choked by water and stalled, thereby ensuring the use effect and service life of the motorboat.

[0026] Furthermore, at least one positioning edge 5 is provided at the port position of the air intake section 1, and the positioning edge 5 is arranged along the length direction of the air intake section 1. Such a structural arrangement ensures that the air intake section 1 and the exhaust pipe of the motorboat will not be misaligned when installed, and the entire device will not rotate abnormally after installation, so that the exhaust section 3 will not be tilted.
[0027] Furthermore, a hoop assembly groove 4 is provided on the outer wall of the air intake section 1 . The hoop assembly groove 4 is provided along the circumference of the air intake section 1 to assist in fixing the air intake section 1 .
[0028] Another object of the present application is to provide an application of any of the above-mentioned integrated consoles in a motorboat. Specifically, the end of the air intake section 1 is connected to the exhaust pipe port of the motorboat.
