Borrow by above-mentioned structure, this air inlet subassembly can filter the air inlet of the fan of assembling this air inlet subassembly, gets rid of dust, impurity etc. in the air, avoids dust etc. in the outside air to carry out the building space along with the air input in the lump. Meanwhile, the noise reduction unit 30 may absorb noise generated by a fan and generated by vibration of a fan pipeline and propagated from the second cavity to the first cavity, so as to reduce noise propagated from the air inlet assembly to the outside.
Specifically, the housing 10 may include an air inlet body 5 and a cylinder body 6 detachably connected to facilitate maintenance of the second filter portion 4 and the noise reduction unit 30 in the housing 10. The air inlet body 5 can comprise a third cavity, the third cavity is communicated with the outside of the air inlet body 5 through two end faces of the air inlet body 5 to form the air inlet portion 1, one end of the cylinder body 6, which is deviated from the air inlet body 5, is provided with the air outlet portion 2, and the first filtering portion 3 comprises a primary filter screen accommodated in the third cavity. Preferably, the third chamber includes an opening 7 to facilitate movement of the primary filter into and out of the third chamber. For example, the air intake body 5 may be a drawer structure, and the first filtering portion 3 may be removably disposed in the third cavity for easy replacement and maintenance. The primary filter screen can be provided with a handle for taking out. The cylinder 6 can gradually reduce from the end connected with the air inlet body 5 to the end with the sectional area deviating from the air inlet body 5.
