In this case, not only is the muffler easily knocked and deformed, affecting the muffling effect of the muffler, but also scalding may occur due to the high temperature on the surface of the muffler. Subsequently, a protective shell is wrapped around the outer periphery of some mufflers, and heat insulation cotton is filled between the muffler and the protective shell. Although this structure has the effects of anti-collision and anti-scalding, it is not easy to disassemble, maintain, and at the same time, the heat insulation cotton has a short service life and high cost.'

The support plate extends along the inner side surface of the protective cover and is attached to the protective cover. Screws sequentially pass through the protective cover and the support plate and are threadedly connected to the preset threaded holes in the support columns.

[0022] The following will further illustrate the concept, specific structure and technical effects of the present utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present utility model.

[0023] It should be noted that in the description of the present utility model, the terms indicating the direction or positional relationship such as "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0024] Referring to Figures 1 - 6 As shown, it is a schematic diagram of a preferred embodiment of the present utility model. The present utility model relates to a silencer with a protection structure, which has: a silencer body 1, a protective cover 2 formed by enclosing a top portion and a peripheral wall portion, and a bottom protective shell 4; the silencer body 1 is a long strip extending along a first direction, and an air inlet and an air outlet are respectively arranged at both ends of the silencer body 1. Further, the silencer body 1 is a structure assembled by splicing up and down, and the splicing parts are clamped with each other through outwardly protruding edges, thereby forming an outwardly protruding annular edge 13 for subsequent installation and connection. A plurality of annular ribs 14 are also provided on the outer peripheral surface of the silencer body 1, and the plurality of annular ribs 14 are arranged at intervals along the first direction to increase the anti-deformation performance of the silencer body 1. The protective cover 2 covers the silencer body 1 from top to bottom and is supported by a support system, so that there is a gap 3 between the inner side surface of the protective cover 2 and the outer peripheral surface of the silencer body 1. The gap 3 provides a buffer space, which is beneficial for the protective cover 2 to absorb external forces; and heat dissipation holes 21 penetrating through the inside and outside are provided on the protective cover 2, which is beneficial for the silencer body 1 to dissipate heat. The bottom protective shell 4 wraps the lower side of the silencer body 1 from bottom to top, and there is an air duct 5 between the bottom protective shell 4 and the silencer body 1. The air duct 5 extends along the first direction and is connected with the gap 3 and the heat dissipation holes 21 on the protective cover 2 together to construct a heat dissipation system. Therefore, the existence of the air duct 5 can not only provide a collision buffer space, but also drive the air flow by using the air pressure difference to further take away the heat on the silencer body and improve the heat dissipation effect. The present utility model can comprehensively wrap the silencer body 1 to avoid scraping and scalding incidents caused by the exposure of the silencer body 1.

[0025] In this embodiment, further, the protective cover 2 is a square elastic wire frame, which has good elasticity and heat dissipation performance and can better protect the silencer body 1. The lower end position of the peripheral wall of the protective cover 2 is lower than the lower end surface of the silencer body 1, and arched notches 22 obtained by cutting from bottom to top are provided on the left and right side walls of the peripheral wall in the first direction. The arched height of the arched notches 22 at least satisfies that the bottom protective shell 4 can be exposed from the arched notches 22, ensuring that while covering the silencer body 1, a convection port for heat dissipation can be provided for the bottom protective shell 4. In this embodiment, further, the bottom protective shell 4 is a U-shaped structure body, which is made by stamping a plate, with a simple structure and convenient production. During assembly, the upward U-shaped end face of the bottom protective shell 4 abuts against the externally convex ring edge 13 preset on the outer periphery of the silencer body 1 and is fixed together by welding. Of course, it can also be assembled by snap connection or screw locking, so that the bottom protective shell 4 plays a role in wrapping the silencer body 1 and constructing a heat dissipation air duct 5.

[0026] Figures 1 - 6 As shown, in this embodiment, the support system is several support columns 11 protruding on the outer peripheral surface of the silencer body 1. The support columns 11 support the inner side surface of the protective cover 2 and are locked with screws 6, stabilizing the protective cover 2 on the outer periphery of the silencer body 1, with a simple structure and convenient disassembly and assembly. The support columns 11 of this embodiment are mainly distributed on the top surface and the left and right side surfaces of the silencer body 1, and a support plate 12 is also erected on the support columns 11 located on the top surface of the silencer body 1. The support plate 12 extends along the inner side surface of the protective cover 2 and is attached to the protective cover 2. The screw 6 sequentially passes through the protective cover 2 and the support plate 12 and is then threadedly connected to the threaded holes preset in the support columns 11. This structure can also utilize the support plate 12 to improve the assembly structure and anti-collision performance, playing a good protective effect. The protective cover 2 of this embodiment is provided with corresponding conforming protective pieces 7 corresponding to the air inlet and air outlet of the silencer body 1 to improve the wrapping and protection, and the conforming protective pieces 7 are locked to the protective cover 2 by screws, which is convenient for assembly and disassembly.

[0027] The utility model cooperates with the protective cover and the bottom protective shell to protect the silencer body, and leaves a gap between the inner side surface of the protective cover and the outer peripheral surface of the silencer body, and there is an air duct between the bottom protective shell and the silencer body. In this way, the protective cover and the bottom protective shell increase the anti-collision performance, and the gap and the air duct both provide a buffer space, improving the protection effect, preventing the silencer body from being scratched and deformed, and also providing a heat dissipation space for the silencer body; the air duct, the gap and the heat dissipation holes on the protective cover construct a heat dissipation system, and can also drive the air flow by using the air pressure difference to further take away the heat on the silencer body and improve the heat dissipation effect. The structure is simple, with few components, no components such as insulating cotton, not only has a good protection effect, avoiding accidental scalding incidents, but also is easy to disassemble and assemble, and has a low investment cost.

[0028] Although the preferred specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention should not be limited to the exact same structure and operation as described above and shown in the drawings. For those skilled in the art of this technology, many equivalent improvements and variations can still be made to the above embodiments through logical analysis, reasoning, or limited experiments without exceeding the concept and scope of the present invention. However, these improvements and variations should all fall within the scope of protection required by the present invention.
