Silencer

The utility model belongs to the technical field of silencing devices, and particularly relates to a silencer which comprises an upper shell provided with an air outlet and a lower shell provided with a first air inlet, a cavity is formed between the upper shell and the lower shell, a silencing mechanism is arranged in the lower shell, specifically, the silencer comprises an air inlet channel connected to the position of the first air inlet, and a second air inlet channel connected to the position of the second air inlet. A baffle is arranged at the end, close to the first air inlet, of the air inlet channel, and the baffle and the inner wall of the air inlet channel are obliquely arranged. The baffle is arranged at the head end of the air inlet channel of the silencer and obliquely arranged, so that airflow can collide with the oblique baffle when entering the silencer, then the flowing direction of the airflow is changed, then the airflow with the changed flowing direction collides with the inner wall of th
