Technical Field
[0001] The utility model relates to the technical field of mufflers, in particular to a muffler assembly. Background Art
[0002] The main function of a car muffler is to reduce the noise generated when a motor vehicle engine is working. A car muffler is mainly composed of three parts: a three-way catalytic converter, a front muffler and a rear muffler. The rear muffler is the core of the entire muffler system.
[0003] When a traditional automobile muffler is driving, water from the outside can easily enter the exhaust system. If the accumulated water is not discharged in time, it can easily flow back into the front muffler pipe. At the same time, the accumulated water can easily freeze in winter, which in turn causes ice to form in the pipe, affecting the starting of the vehicle. Utility Model Content

[0020] The utility model provides a muffler assembly, including a front exhaust pipe 101, a front muffler 102, a rear exhaust pipe 103, a shell 104, an exhaust tail pipe 105 and a waterproof component 106, wherein the waterproof component 106 includes a partition 107, a water baffle 108, a connecting pipe 109, a drainage seat 110, a first sealing seat 111, a sealing member 112, a limit plate 114 and a first guide rod 115, and the curved portion on the exhaust tail pipe 105 is used to prevent external accumulated water from entering the shell 104, and the water baffle 108 is used to prevent the accumulated water from flowing back into the rear exhaust pipe 103. Finally, when there is accumulated water in the shell 104, the first sealing seat 111 can rise under the action of buoyancy, so that the accumulated water can be discharged through the drain port 113. It can be understood that the above scheme can be used to prevent external accumulated water from entering the shell 104, and can also be used to solve the problem of timely discharging the accumulated water in the shell 104.
[0021] According to this specific embodiment, the front muffler 102 is installed on the front exhaust pipe 101, the rear exhaust pipe 103 is installed on the front muffler 102, the shell 104 is installed on the rear exhaust pipe 103, and the exhaust tail pipe 105 is installed on the shell 104. Two exhaust tail pipes 105 are provided and are respectively located on the left and right sides of the shell 104. The exhaust gas of the automobile enters the front muffler 102 through the front exhaust pipe 101, then enters the rear exhaust pipe 103, and enters the shell 104 through the rear exhaust pipe 103, and is finally discharged through the two exhaust tail pipes 105.
[0022] The water baffle 108 is fixedly connected to the shell 104, located inside the shell 104, and sleeved on the exhaust tail pipe 105. The partition 107 is fixedly connected to the shell 104, located inside the shell 104, and sleeved on the exhaust tail pipe 105. The connecting pipe 109 is fixedly connected to the water baffle 108 and passes through the water baffle 108. The drain seat 110 is fixedly connected to the shell 104, connected to the shell 104, and located on one side of the shell 104. The first sealing seat 111 is slidably connected to the drain seat 110 and is arranged on the drain seat 110. The sealing member 112 is arranged On the drain seat 110, two water baffles 108 are provided, and a partition 107 is provided on both sides of one water baffle 108. The two water baffles 108 divide the shell 104 into three chambers, the middle one is an exhaust chamber 116, and the two sides are waterproof chambers 117. The exhaust gas first enters the exhaust chamber 116, at which time the exhaust gas is reflected and interfered by the through holes on the partition 107, and the sound energy is gradually weakened, and then enters the waterproof chamber 117 through the connecting pipe 109, and the sound energy is weakened again by the partition 107, and finally discharged through the exhaust tail pipe 105; the exhaust tail pipe 105 opens downward, and a curved portion higher than the opening is provided on the pipe body. The outer shell 104 is provided with a drain seat 110, which is provided with a drain port 113. The density of the first sealing seat 111 is less than that of water. When the outer shell 104 is provided with a drain port 113, the water in the first sealing seat 1 ... The water in the first sealing seat 111 is provided with a drain port 113. The water in the first sealing seat 111 is provided with a drain port 113. The water in the second sealing seat 111 is provided with a drain port 113. The water in the second sealing seat 111 is provided with a drain port 113. The water in the second sealing seat 111 is provided with a drain port 113. The water in the second sealing seat When there is no water accumulation inside, the first sealing seat 111 descends under the action of gravity, and then seals the drain port 113 on the drain seat 110. When water accumulates inside the shell 104, since the density of the first sealing seat 111 is less than the density of water, the first sealing seat 111 can float up, and at this time the drain port 113 is opened, so that the water accumulated inside the shell 104 can be discharged in time. After the water is discharged, the first sealing seat 111 is reset under the action of gravity, and then the drain port 113 is re-sealed, so as to prevent the external water from entering the shell 104 and discharge the water accumulated inside the shell 104 in time.
[0023] Secondly, the limiting plate 114 is fixedly connected to the drain seat 110 and is arranged on the drain seat 110; the movement of the first sealing seat 111 is limited by the limiting plate 114, so that the first sealing seat 111 stops rising after rising to the limiting plate 114.
[0024] At the same time, the first guide rod 115 is fixedly connected to the limiting plate 114 and slidably connected to the first sealing seat 111, and is located on the side of the limiting plate 114 close to the first sealing seat 111. The movement of the first sealing seat 111 is guided by the first guide rod 115 to prevent the first sealing seat 111 from tilting and affecting the sealing of the drain seat 110.
[0025] When the muffler assembly of this embodiment is used, the curved portion on the exhaust tail pipe 105 prevents external accumulated water from entering the shell 104 through the exhaust tail pipe 105, and the water baffle 108 prevents the accumulated water inside the shell 104 from flowing back into the rear exhaust pipe 103; when there is accumulated water inside the shell 104, the accumulated water will flow to the drain seat 110, and at this time the first sealing seat 111 rises under the action of buoyancy, thereby opening the drain port 113, and the accumulated water inside the shell 104 can be discharged through the drain port 113, thereby achieving the purpose of discharging the accumulated water in time.
[0026] Second embodiment:
[0027] Based on the first embodiment, please refer to Figure 4 , Figure 4 2 is a schematic diagram of the installation structure of the second sealing seat of the second embodiment. The sealing component 112 of this embodiment includes a mounting seat 201 , a second sealing seat 202 and a second guide rod 203 .

The density of the second sealing seat 202 is less than that of water. When the external water accumulates over the drain seat 110, the second sealing seat 202 rises under the action of buoyancy, thereby sealing the mounting seat 201. At this time, the external water cannot enter the shell 104 through the mounting seat 201 and the drain seat 110, thereby preventing the external water from entering the shell 104 through the drain seat 110.
