[0025] See also Figure 1-3 The utility model provides a new technical solution: an air filter inlet pipe structure with a muffler, comprising a first muffler connecting pipe 1, a second muffler connecting pipe 2 is arranged on the upper surface of the first muffler connecting pipe 1, and a slide groove 3 is opened on the outer surface of the first muffler connecting pipe 1;

[0026] The disassembly mechanism is arranged on the first muffler connecting pipe 1 and is used for disassembly of the muffler pipe after connection. The disassembly mechanism includes two springs 4, and the two springs 4 are fixedly installed in the inner wall of the slide groove 3;

[0027] The sealing mechanism is arranged on the first muffler connecting pipe 1 . The sealing mechanism is used for sealing after the muffler pipe is connected. The sealing mechanism includes a sealing groove 9 . The sealing groove 9 is opened in the inner wall of the first muffler connecting pipe 1 .

[0028] Furthermore, the disassembly and assembly mechanism also includes two pressure plates 5 and a ring 6. The two pressure plates 5 are fixedly mounted on the upper ends of the two springs 4, and the upper surfaces of the two pressure plates 5 are inclined. The ring 6 is fixedly sleeved on the outer surfaces of the two pressure plates 5, and the ring 6 is slidably sleeved in the inner wall of the slide groove 3.

[0029] Furthermore, two round holes 7 are formed on the inner wall of the slide groove 3 , and two round balls 8 are disposed on the inner walls of the two round holes 7 .

[0030] Furthermore, the disassembly and assembly mechanism also includes a limit plate 12 and a first magnetic ring 13 . The limit plate 12 is fixedly installed in the inner wall of the first muffler connecting pipe 1 , and the first magnetic ring 13 is fixedly installed on the upper surface of the limit plate 12 .

[0031] Furthermore, the disassembly and assembly mechanism also includes a second magnetic ring 14 , which is fixedly mounted on the lower end of the second muffler connecting pipe 2 .

[0032] Furthermore, the sealing mechanism also includes a rubber sealing ring 10, which is fixedly sleeved on the outer surface of the second muffler connecting pipe. When the air filter inlet pipe structure with a muffler is used, the second muffler connecting pipe 2 is inserted into the inner wall of the first muffler connecting pipe 1. At this time, a downward thrust is applied to the collar 6, so that the collar 6 drives the two pressure plates 5 sleeved on the inner surface to move downward, and at the same time, the two pressure plates 5 apply pressure to the two springs 4 fixedly installed on the lower surface to cause them to shrink. At this time, the two pressure plates 5 are no longer located above the two circular holes 7, and the round balls 8 in the two circular holes 7 are no longer under pressure. At this time, the second muffler connecting pipe 2 is inserted into the inner wall of the first muffler connecting pipe 1, and no thrust is applied to the collar 6. At the same time, the spring 4 is no longer under pressure. At this time, the spring 4 expands, and the spring 4 applies an upward thrust to the pressure plate 5 fixedly installed at the upper end to move upward. While moving upward, the pressure plate 5 hits the round ball 8 to make it snap into the card slot 11 for fixation, and during installation, the limiting The positioning plate 12 limits the second muffler connecting pipe 2, so that the groove 11 opened on its outer surface is easier to align with the circular hole 7 for fixation, and can be reinforced by the adsorption alignment and fixation of the first magnetic ring 13 and the second magnetic ring 14. After installation, the rubber sealing ring 10 fixedly sleeved on the outer surface of the second muffler connecting pipe 2 is filled into the sealing groove 9 for sealing. The air filter inlet pipe structure with a muffler can quickly install the muffler pipe by snapping. Compared with the traditional adhesive fixation, it is not only firmly fixed, but also can be disassembled to maintain the inside of the muffler pipe, which is more convenient. In addition, the air filter inlet pipe structure with a muffler can better align the groove 11 with the round ball 8 through the limiting plate 12 during installation, making the operation simple, and the fixation can be reinforced by the adsorption of two magnetic rings, which is more convenient. In addition, the air filter inlet pipe structure with a muffler can be filled into the sealing groove 9 for sealing by the rubber sealing ring 10, thereby ensuring the sealing of the muffler.

[0033] Working principle: When the air filter inlet pipe structure with silencer is used, the second silencer connecting pipe 2 is inserted into the inner wall of the first silencer connecting pipe 1. At this time, a downward thrust is applied to the collar 6, so that the collar 6 drives the two pressure plates 5 sleeved on the inner surface to move downward. At the same time, the two pressure plates 5 apply pressure to the two springs 4 fixedly installed on the lower surface to cause them to shrink. At this time, the two pressure plates 5 are no longer located above the two circular holes 7, and the round balls 8 in the two circular holes 7 are no longer under pressure. At this time, the second silencer connecting pipe 2 is inserted into the inner wall of the first silencer connecting pipe 1. At this time, no thrust is applied to the collar 6, and the springs 4 are compressed. The spring 4 is no longer under pressure, and the spring 4 expands. The spring 4 applies an upward thrust to the pressure plate 5 fixed at the upper end to make it move upward. While moving upward, the pressure plate 5 hits the ball 8 to make it snap into the slot 11 for fixation, and during installation, the second muffler connecting pipe 2 is limited by the limiting plate 12, so that the slot 11 opened on its outer surface is easier to align with the circular hole 7 for fixation, and can be reinforced by the adsorption, alignment and fixation of the first magnetic ring 13 and the second magnetic ring 14. After installation, the rubber sealing ring 10 fixedly mounted on the outer surface of the second muffler connecting pipe 2 is filled into the sealing groove 9 for sealing.
