[0002] Noise reduction refers to reducing or eliminating noise through a series of technical means to improve the environment and protect people's health. Silencers are needed for noise reduction. Silencers, also known as mufflers, are a device used to reduce or control the propagation of sound. They are widely used in various fields. Mufflers are installed in the air intake or exhaust ducts of equipment such as blowers, air compressors, and generators to silence them.

[0003] After searching, the announcement number is CN210860253U, and the name is a silencer, including a No. 1 silencer and a No. 2 silencer. Through research and analysis, it is found that although the advantage of reducing the noise generated by the airflow can be achieved, the following disadvantages still exist to a certain extent.

[0004] For example, due to the difficulty in installation and the lack of convenient installation function, the silencer cannot be installed quickly, which reduces the efficiency of the silencer installation. Moreover, when in use, it does not have the function of filtering the passing airflow, which will cause dust to enter the silencer and accumulate inside the silencer, thereby affecting the silencer effect. In order to solve the above technical problems, we have designed a silencer that is easy to install. Utility Model Content
