The utility model provides a cigarette machine oil net 10, as shown in figure 1 and figure 2, this cigarette machine oil net 10 includes net dish 1, wire 2 and blade 3, wherein above-mentioned net dish 1 is circular, above-mentioned wire 2 is equipped with a plurality of, and a plurality of wire 2 radially installs in net dish 1, interval setting and circumference equipartition in net dish 1 between a plurality of wire 2, form fan-shaped clearance between two adjacent wire 2, through along 1 radial installation wire 2 of net dish, make wire 2 whole be radial, do not have the structure that circumference set up, can make wire 2 intercept oil drip back centrifugation throw away fast, do not hang oily greasy dirt. And the diameter of the metal wire 2 is small, the resistance is small, and oil is not easy to hang. Further, in this embodiment, the oil-repellent paint may be coated on the metal wire 2, so as to further reduce the possibility of oil hanging of the metal wire 2.

Above-mentioned blade 3 is equipped with a plurality ofly and radially installs in net dish 1, 3 circumference equipartitions of a plurality of blades are in net dish 1, every blade 3 is arranged in between two adjacent metal silk 2, it is L shape structure, on the one hand blade 3 can be as the spoke of net dish 1, play the effect of supporting and strengthening whole cigarette machine oil net 10, on the other hand, when blade 3 rotates along with impeller 30, blade 3 can also play axial fan's effect, offset because of the pressure loss that the metal silk 2 interception oil drips and lead to, improved cigarette machine oil net 10's result of use. In this embodiment, the width of the blade 3 is larger than the diameter of the wire 2.

As shown in fig. 1 and 2, the blade 3 includes a first plate connected to the mesh plate 1 in a fan-shaped configuration having a minimum width greater than the diameter of the wire 2, and a second plate disposed perpendicular to the first plate. The arrangement of the structure can enable the blades 3 to offset the pressure loss caused by oil drops intercepted by the metal wires 2 on the basis of strengthening the structural strength of the oil screen 10 of the range hood. Alternatively, the number of the vanes 3 may be 6-8, which can reduce the resistance and simultaneously meet the requirement of the supporting strength of the smoke net 10.

In this embodiment, the blade 3 is preferably integrally formed with the mesh plate 1, and specifically, the blade 3 and the mesh plate 1 may be formed by stamping a sheet metal part. Through the stamping forming process, the mesh disc 1 and the blades 3 can be manufactured more quickly and at lower cost.
