Description

Technical Field

[0001] The utility model relates to the technical field of mufflers, in particular to a muffler. Background Art

[0002] A blower silencer is a device used to reduce the noise of a blower (fan), usually installed on the air outlet or duct of the blower. They reduce the noise generated by the blower by absorbing, isolating or reflecting sound, and provide a quieter working environment. The design principles of blower silencers include the following: Sound-absorbing silencers: Use sound-absorbing materials (such as sound-absorbing cotton, glass fiber, etc.) to absorb the noise generated by the blower, convert sound energy into heat energy, and thus reduce the propagation of noise. Sound-isolating silencers: Reduce the propagation of sound by isolating two spaces. This type of silencer is usually composed of multiple layers of sound insulation boards with sound-absorbing materials sandwiched in the middle, which effectively isolates the noise generated by the blower. Reflective silencers: Transfer the sound out of the blower system by reflecting it, reducing the propagation of noise. This type of silencer usually uses materials or structures with reflective properties, such as metal plates, angle irons, etc.

[0003] The prior art can reduce the noise of the blower through a muffler, but various debris such as leaves, branches, and plastic bags are easily blown into the outdoor muffler, which affects the noise reduction effect of the muffler. In addition, it is inconvenient to replace the muffler sheet on the muffler. Therefore, those skilled in the art provide a muffler to solve the problems raised in the above background technology.
