[0038] , in this embodiment, the sound-absorbing partition 2 is connected to the housing by welding or snap connection.

[0039] Please refer to Figures 1-2 , 4, the sound-absorbing partition 2 is provided with a sound-absorbing unit. The sound-absorbing unit is a hole provided on the sound-absorbing partition 2 or a pipe provided on the sound-absorbing partition 2.

[0042] Working principle:

[0043] Before the outside air enters the engine, the air filter will prevent impurities such as dust, sand, and particulate matter in the air from entering the engine, reducing the wear and damage of the internal components of the engine to them, and improving its reliability and durability. The clean air enters the engine combustion chamber through the filter element, providing high-quality air to the engine and improving the combustion efficiency and the best state of the engine performance.

[0044] An anechoic cavity is integrated in the air filter, and a sound-absorbing partition 2 is added inside the air filter. The sound-absorbing partition 2 is provided with sound-absorbing units such as holes and pipes; the sound-absorbing partition 2 is disposed inside the air filter and forms an anechoic cavity with the air filter housing, integrating the sound-absorbing and filtering functions. Not only can clean air enter the engine, but when the air passes through the anechoic cavity, the sound-absorbing partition 2 will guide the air flow to undergo multiple reflections and refractions, thereby gradually reducing the energy of the air flow and reducing the noise generated by the engine intake system, providing a quieter driving environment. By changing the volume of the cavity, specific frequency noises can be eliminated.
