Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 8 The present invention provides a technical solution: a waste heat recovery muffler for a motorcycle, comprising a clamping tube 1, a transmission tube 11 arranged at one end of the clamping tube 1, and a partition tube 2 arranged outside the transmission tube 11, the clamping tube 1 is arc-shaped, the transmission tube 11 is installed at one end of the clamping tube 1, the end of the transmission tube 11 connected to the clamping tube 1 is conical, a plurality of connection end blocks 13 are installed at the conical end of the transmission tube 11, threaded holes are provided on the surface of the connection end blocks 13, a plurality of limiting grooves are provided at the conical end of the transmission tube 11, the connection end blocks 13 and the limiting grooves are staggered, and a heat absorption mechanism 3 is clamped inside the limiting groove;

[0030] A silencer mechanism 4 is provided inside the transmission pipe 11, and the silencer mechanism 4 is clamped at one end where the clamping tube 1 is connected to the transmission pipe 11. A blocking mechanism 5 is clamped at the bottom of the transmission pipe 11. When the silencer is used, the exhaust gas of the motorcycle is transported to the inside of the clamping tube 1 after simple screening, and can subsequently absorb part of the heat of the clamping tube 1 with the help of the heat absorption mechanism 3 to prevent the internal stability of the transmission pipe 1 from being too high during subsequent processing. The silencer mechanism 4 is used to reduce the noise during the transmission process, and the blocking mechanism 5 is used to guide and adsorb the exhaust gas when it is discharged, so as to avoid a large amount of particulate matter from being mixed into the air, thereby reducing pollution to the environment.

[0031] like Figure 2 As shown, in order to achieve the effect of sound insulation, the separator tube 2 is arranged on the outside of the transmission tube 11, and a plurality of limit bolts are inserted on the separator tube 2, and the limit bolts are clamped in the threaded hole on the top of the connecting end block 13. The inner diameter of the separator tube 2 is equal to the outer diameter of the transmission tube 11. A plurality of arc grooves are opened on the surface of the separator tube 2, and a plurality of sound insulation boards 22 are installed inside the arc grooves. A plurality of buffer pressing sheets 21 are installed on the inner wall of the separator tube 2. The buffer pressing sheet 21 is in a "J" shape and abuts against the outside of the heat absorption mechanism 3 for auxiliary limiting. The sound insulation board 22 can be used to reduce the noise generated during the exhaust gas transportation inside the transmission tube 11, and reduce the noise generated during the operation of the motorcycle. Excessive noise causing nuisance to the public.

[0032] like Figure 7 As shown, since the internal temperature of the clamping tube 1 will rise during the process of conveying exhaust gas, the heat absorption mechanism 3 includes a water storage plate 31 and a piston cavity 32. The water storage plate 31 is clamped inside the limit groove. A positioning groove is opened at the rear end of the water storage plate 31, and the position of the positioning groove corresponds to the buffer pressing plate 21. The piston cavity 32 is installed at the bottom of the water storage plate 31. The piston cavity 32 is connected with the water storage plate 31. A plurality of heat conducting plates 36 are installed on the outer wall of the water storage plate 31. The heat conducting plates 36 are against the surface of the clamping tube 1. Heat sinks 12 are arranged between the heat conducting plates 36. The heat sinks 12 Fixedly connected to the outer wall of the card tube 1, the heat sink 12 and the water storage plate 31 are arranged in a staggered manner. With the help of the heat conductive sheet 36 and the heat sink 12, the heat can be discharged, and the upper limit of the temperature inside the card tube 1 can be maintained, so that the temperature is at a relatively stable point, avoiding the internal temperature channel that causes the deformation of the materials inside and outside the muffler, and the heat conductive sheet 36 can conduct heat to the water in the storage plate 31, so that it continues to heat up, which is used to generate steam to drive the piston plate inside the piston chamber 32 to move, thereby moving the transmission plug plate 34.

[0033] like Figure 8As shown, the exhaust gas contains a lot of particulate matter and debris, which are easily accumulated inside the transmission pipe 11. A piston plate is movably provided inside the piston chamber 32, and a transmission plug plate 34 is movably provided at the bottom of the piston chamber 32. The top of the transmission plug plate 34 is installed at the bottom of the piston plate. An adsorption plate 33 is installed at the bottom of the piston chamber 32. The adsorption plate 33 is used to adsorb dust and debris in the exhaust gas. A plurality of movable shafts 35 are installed on the transmission plug plate 34. A spiral shaft-shaped adsorption sheet can be provided on the movable shaft 35 to clean the surface of the adsorption plate 33. The movable shaft 35 is pressed against the adsorption sheet. On the surface of the plate 33, the movable shaft 35 is elastic, and the two ends of the movable shaft 35 are clamped with limit rods 351, which are arc-shaped and made of metal. With the help of the adsorption plate 33, some particulate matter and debris in the exhaust gas can be adsorbed, which can extend the cleaning and maintenance cycle of the muffler. As the transmission plug plate 34 moves, the movable shaft 35 can be driven to assist in cleaning the surface of the adsorption plate 33, and the condensed oil and debris are gathered near the movable shaft 35, so as to avoid excessive accumulation of impurities on the surface of the adsorption plate 33 affecting the subsequent adsorption and separation effect.

[0034] like Figure 4 As shown, in order to reduce the noise of the motorcycle during operation, the silencer mechanism 4 includes a limit tube 41, one end of which is clamped inside the clamping tube 1, a connecting ring is installed on the top of the limit tube 41, and a delivery pipe 43 is installed inside the connecting ring. The surface of the delivery pipe 43 is provided with a plurality of exhaust holes, and the exhaust holes are used for diversion, thereby reducing the noise generated during the activity of the exhaust gas. During the airflow transmission process, the air can be transmitted along the delivery pipe 43, and the exhaust gas can be diverted under the action of the exhaust holes, thereby reducing the noise generated during its flow transmission process.

[0035] In order to avoid the noise caused by the collision of particulate matter in the exhaust gas and the inside of the transmission pipe 11, an arc groove is opened on the surface of the limit tube 41, and the arc groove is evenly arranged in an array on the outside of the limit tube 41, and a plurality of silencer rings 42 are installed inside the limit tube 41. The silencer rings 42 are evenly arranged on the outer wall of the transmission pipe 43. The silencer rings 42 and the exhaust holes are staggered. The silencer rings 42 have a certain arc shape and can play a role in guiding flow. The exhausted exhaust gas can flow back to the surrounding adsorption plates 33 along the action of the silencer rings 42, and can adsorb excess particulate matter in the exhaust gas, which is convenient for subsequent unified maintenance, and can also reduce the impact of the particulate matter on the inside of the transmission pipe 11 following the airflow, thereby reducing noise.

[0036] like Figure 5As shown, in order to control the noise generated by excessive exhaust gas emission, the blocking mechanism 5 includes a clamping ring 51, which is clamped on the bottom of the inner wall of the transmission pipe 11. A plurality of metal connecting plates are installed inside the clamping ring 51, and a guide bowl 52 is installed between the metal connecting plates. A buffer ball 53 is installed inside the guide bowl 52. The buffer ball 53 is used for airflow guidance. When the airflow is transmitted to the top end of the blocking mechanism 5, the airflow impacts the buffer ball 53, which can guide the airflow in cooperation with the guide bowl 52, diffuse the airflow to the surroundings, play a buffering role, and reduce the noise during the emission process.

[0037] like Figure 6 As shown, during the exhaust gas discharge process, small particles and debris are often mixed into the air. A plurality of connecting ribs 54 are installed inside the guide bowl 52. The connecting ribs 54 are arranged in a uniform array inside the guide bowl 52. A support plate 55 is installed at one end of the connecting ribs 54. The support plate 55 has a "V"-shaped cross-section and is arranged in a uniform array outside the buffer ball 53. A card slot is provided inside the support plate 55, and a plurality of adsorption sheets 56 are provided inside the card slot. A grid plate can be provided inside the adsorption sheet 56. During the diversion process, the exhaust gas can pass through the adsorption sheet 56. Under the layer-by-layer screening effect of the grid plate, the excess particles and debris in the exhaust gas can be quickly adsorbed, which can reduce the emission of the motorcycle and has a good environmental protection effect. The adsorption sheet 56 can be cleaned and maintained regularly.

[0038] Working principle: First, when using the silencer, the exhaust gas of the motorcycle is simply screened and then transported to the inside of the card tube 1. Subsequently, the heat absorbing mechanism 3 can absorb part of the heat of the card tube 1 to prevent the internal stability of the transmission tube 11 from being too high during the subsequent processing, and the silencer mechanism 4 can be used to reduce the noise during the transmission process. When the exhaust gas is discharged, the blocking mechanism 5 plays a role of diversion and adsorption to prevent a large amount of particles from mixing into the air. As the heat sink 12 and the heat conducting plate 36 can reduce the temperature inside the suction transmission tube 11, and the water storage plate 31 is heated up, the piston block inside the piston cavity 32 can be pushed to move under the action of steam pressure, and the transmission plug plate 34 at the bottom can be moved. The movable shaft 35 can clean both sides of the adsorption plate 33 to prevent a large amount of dirt particles from accumulating and affecting the subsequent adsorption effect. The movable shaft 35 can move around the metal limit rods 351 at both ends, and can increase the swing effect during the friction between the movable shaft 35 and the surface of the adsorption plate 33, thereby further enhancing the cleaning effect.

[0039] Then, during the air flow transmission process, the exhaust gas can be transmitted along the delivery pipe 43, and the exhaust gas can be diverted under the action of the exhaust hole, which can reduce the noise generated during the flow transmission process, and the exhausted exhaust gas can flow back to the surrounding adsorption plates 33 along the action of the silencer ring 42, which can adsorb and process the excess particles in the exhaust gas, which is convenient for subsequent unified maintenance, and can also reduce the impact of the exhaust gas on the inside of the transmission pipe 11 by following the air flow, thereby reducing noise;

[0040] Finally, when the airflow is transmitted to the top end of the blocking mechanism 5, the airflow impacts the buffer ball 53, which can guide the airflow in cooperation with the guide bowl 52, diffuse the airflow to the surroundings, and play a buffering role. In the process of diversion, the exhaust gas can pass through the adsorption sheet 56. Under the layer-by-layer screening effect of the grid plate, the excess particulate debris in the exhaust gas can be quickly adsorbed, which can reduce the emission of the motorcycle and has a good environmental protection effect.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
