Detailed Description
The following describes specific embodiments of the present utility model with reference to the drawings.
As shown in fig. 1 and 2, a negative pressure fan device capable of filtering air greasy dirt comprises a negative pressure fan 3, wherein a wind scooper 4 is arranged on the outer ring of the negative pressure fan 3, and when in use, air with greasy dirt is driven by the negative pressure fan 3 to enter the wind scooper 4. The air outlet end of the air guide cover 4 is provided with an oil collecting cover 5, the oil collecting cover 5 and the air guide cover 4 are integrally formed, the oil collecting cover 5 is provided with an arc end face, oil stains can flow to the lower end face of the inner side of the oil collecting cover 5 after colliding with the arc end face of the oil collecting cover 5, then the oil stains are collected into the lower end face of the inner ring of the air guide cover 4, the center of the oil collecting cover 5 is provided with an air outlet 6, and air filtered by the oil stains is discharged from the air outlet 6.
As shown in fig. 1 and 2, one end of a belt wheel transmission assembly 2 is connected to a central rotating shaft of the negative pressure fan 3, the other end of the belt wheel transmission assembly 2 is connected with a driving motor 1, and the driving motor 1 drives the negative pressure fan 3 to work through the belt wheel transmission assembly 2.
As shown in fig. 2 and 3, an oil drain port 12 is arranged on the lower end surface of the inner ring of the air guide cover 4, and the oil drain port 12 is used for draining oil stains outwards.
In order to ensure that oil stains can flow into the oil drain port 12, as shown in fig. 2 and 3, an oil collecting groove 11 with a circular arc-shaped cross section is arranged on the lower end surface of the inner ring of the air guide cover 4, the oil collecting groove 11 can collect the oil stains flowing onto the lower end surface of the inner ring of the air guide cover 4, and the oil drain port 12 is positioned in the oil collecting groove 11.
