DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a new technical solution: a muffler outlet pipe for easy replacement of a filter layer, comprising a muffler housing 1, an exhaust pipe 2 is fixedly installed on the right surface of the muffler housing 1, a muffler sealing cover 3 is arranged on the left surface of the muffler housing 1, and an intake pipe 4 is fixedly installed on the left surface of the muffler sealing cover 3;

[0025] The disassembly and assembly mechanism is on the muffler sealing cover 3 and is used for disassembly and assembly of the muffler to replace the filter layer inside the muffler. The disassembly and assembly mechanism includes a first slide groove 5, which is provided on the outer surface of the muffler sealing cover 3;

[0026] The positioning mechanism is on the inner surface of the muffler housing 1 . The positioning mechanism is used for auxiliary positioning when the filtering device is installed. The positioning mechanism includes a positioning block 13 . The positioning block 13 is fixedly mounted on the inner surface of the muffler housing 1 .

[0027] Furthermore, the disassembly and assembly mechanism also includes two springs 6 and two pressure plates 7. The two springs 6 are fixedly installed in the inner wall of the first slide groove 5. The two pressure plates 7 are fixedly installed at the right ends of the two springs 6, and the opposite surfaces of the two pressure plates 7 are inclined.

[0028] Furthermore, the disassembly and assembly mechanism also includes a circular ring 8 , which is fixedly sleeved on the outer surfaces of the two pressing plates 7 , and the circular ring 8 is slidably connected to the first sliding groove 5 .

[0029] Furthermore, two round holes 9 are formed on the inner wall of the first slide groove 5 , and round balls 10 are disposed in the two round holes 9 .

[0030] Furthermore, two slots 11 are formed on the outer surface of the muffler housing 1 .

[0031] Furthermore, the positioning mechanism further includes a silencer filter element 12 and a second slide groove 14. The silencer filter element 12 is arranged on the inner surface of the silencer housing 1, and the second slide groove 14 is opened on the outer surface of the silencer filter element 12.

[0032] When the silencer outlet pipe which is convenient for replacing the filter layer is used, a leftward thrust is applied to the circular ring 8, so that the circular ring 8 drives the two pressure plates 7 sleeved on the inner surface to move to the left, and at the same time, the two pressure plates 7 apply pressure to the two springs 6 fixedly installed on the left surface to cause them to shrink. At this time, the two pressure plates 7 are no longer located above the two circular holes 9, and the round balls 10 in the two circular holes 9 are no longer under pressure. At this time, the silencer housing 1 is inserted into the silencer sealing cover 3, and no thrust is applied to the circular ring 8, and at the same time, the spring 6 is no longer under pressure. At this time, the spring 6 expands, and the spring 6 applies a rightward thrust to the pressure plate 7 fixedly installed on the right end to cause it to move to the right. While moving to the right, the pressure plate 7 hits the round ball 10 to make it snap into the card slot 11 for fixation. When the sound filter is in place, when the silencer is opened, the silencer is moved to the right along the positioning block 13 through the slide groove provided on the outer surface of the silencer filter 12 to complete the plug-in. After the installation is completed, it can be fixed again by pushing the ring 8 and repeating the operation. The silencer outlet pipe, which is convenient for replacing the filter layer, can be installed and disassembled by snap-fitting, without the need for additional window openings, thereby improving the overall sealing of the silencer and being simple to operate. The silencer can be quickly opened to replace the internal filter element, which is more convenient and practical. The silencer outlet pipe, which is convenient for replacing the filter layer, can be accurately installed through the slide groove provided on the outer surface of the positioning block 13 and the silencer filter element 12, so that the silencer filter element can be accurately installed, and the silencer housing will not be impacted by external sound vibrations, thereby better noise reduction can be performed.

[0033] Working principle: when the muffler outlet pipe which is convenient for replacing the filter layer is used, a leftward thrust is applied to the circular ring 8, so that the circular ring 8 drives the two pressure plates 7 sleeved on the inner surface to move to the left, and at the same time, the two pressure plates 7 apply pressure to the two springs 6 fixedly installed on the left surface to cause them to shrink. At this time, the two pressure plates 7 are no longer located above the two circular holes 9, and the round balls 10 in the two circular holes 9 are no longer under pressure. At this time, the muffler housing 1 is inserted into the muffler sealing cover 3, and no thrust is applied to the circular ring 8 at this time, and the spring 6 is no longer under pressure. At this time, the spring 6 expands, and the spring 6 applies a rightward thrust to the pressure plate 7 fixedly installed on the right end to move it to the right. While moving to the right, the pressure plate 7 hits the round ball 10 to make it snap into the card slot 11 for fixing. When replacing the muffler filter element, when the muffler is opened, it moves to the right along the positioning block 13 through the slide groove opened on the outer surface of the muffler filter element 12 to complete the plug-in. After the installation is completed, it can be fixed again by pushing the circular ring 8 and repeating the operation.
