[0027] The following is combined with Figure 1-5 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0028] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "end", "front", "back", "middle", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it is not described in detail in this embodiment.

[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] like Figures 1 to 3 As shown, a silencer comprises:

[0032] A tube body 1 is a hollow structure with two ends connected to form an air inlet 11 and an air outlet (not shown). An accommodating portion 12 is provided on the inner wall on both sides of the tube body 1. The inner wall of the tube body 1 is also provided with sound-absorbing material. In this embodiment, the tube body 1 is a galvanized steel plate, and the sound-absorbing material is glass wool or polyurethane foam.

[0033] A filter device 2 is detachably connected to the tube body 1; specifically, the filter device 2 includes a filter screen 21, which is used to block dust in the airflow to prevent dust from adhering to the inner wall of the tube body 1 and being difficult to clean. Both sides of the filter screen 21 are provided with a mounting portion 22 that matches the accommodating portion 12. Specifically, the mounting portion 22 is inserted into the accommodating portion 12 by snapping to fix the filter screen 21; at least one protrusion 23 is also provided on the surface of the filter screen 21. In this embodiment, there are two protrusions 23, which are respectively provided above and below the front end surface of the filter screen 21. The protrusion 23 is convenient for the user to pull the filter screen 21 out of the tube body 1 to clean and replace the filter screen 21.

[0034] A protective member 3 is wrapped around the pipe body 1. The protective member 3 includes a fireproof layer 31 and a protective layer 33. The fireproof layer 31 abuts against the pipe body 1. The fireproof layer 31 and the protective layer 33 are connected by an adhesive layer 32. In this embodiment, the fireproof layer 31 is a fireproof board or fireproof cotton, the adhesive layer is high-temperature glue, and the protective layer 33 is a steel plate. In other embodiments, the fireproof layer 31 is fireproof cotton, which will not be described in detail. The protective layer 33 is used to protect the fireproof layer 31 to prevent the fireproof layer 31 from being damaged. The fireproof layer 31 has a good fireproof effect, so that the pipe body 1 not only has a sound-absorbing effect, but also has a fireproof effect.

[0035] like Figure 1 As shown, a mounting assembly 4 is connected to the tube body 1, and the mounting assembly 4 includes at least one frame 41 and a mounting member 42 detachably connected to the frame 41. The frame 41 is against the tube body 1, and the mounting member 42 is a hollow structure with two ends connected. In this embodiment, each mounting assembly 4 is provided with two frames 41 and one mounting member 42.

[0036] The frame 41 includes a bottom component 411, and side components 412 are respectively provided on both sides of the bottom component 411, and a top component 413 is respectively connected to the side components 412 on both sides. In this embodiment, the bottom component 411, the side component 412 and the top component 413 can be combined by bolt connection or clamping, etc., which is convenient for users to assemble on site and reduce the area for customers to carry products, making transportation convenient.

[0037] like Figure 4 and Figure 5 As shown, at least one shock absorbing device 5 (specifically two) is provided in the bottom member 411, and the shock absorbing device 5 includes a shell 51, and an elastic member 52 and a support member 53 connected to the elastic member 52 are provided in the shell 51, and the support member 53 is partially provided outside the shell 51. When the air flows quickly, the air passing through the tube body 1 will cause shaking. By providing the shock absorbing device 5, the vibration between the frame 41 and the tube body 1 is reduced, and the noise generation is also reduced to a certain extent.

[0038] Specifically, the support member 53 includes a base 531 and a support portion 532 disposed on the base 531. The support portion 532 is partially located outside the housing 51. A stopper 511 is provided on the top of the housing 51 in the direction of the support portion 532. The base 531 can reciprocate between the stopper 511 and the elastic member 52. The stopper 511 is provided to prevent the support member 53 from falling out of the housing 51. In this embodiment, the elastic member 52 is a spring; in other embodiments, the elastic member 52 may also be a spring or rubber, which will not be described in detail here.

[0039] The technical effects of this utility model are mainly reflected in the following aspects:

[0040] The silencer not only reduces noise and prevents fire, but also has the function of filtering dust.

[0041] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
