The free end portion a of the horizontal portion 111 and the free end portion B of the inclined portion 112 adjacent thereto have a certain distance therebetween and are located on the same vertical plane, two adjacent horizontal portions 111 are located on the same horizontal plane, and a slit 120 through which oil smoke passes is formed between two adjacent hollow tubes 110. According to the direction of the oil smoke flowing into the slit 120, the side of the hollow tube 110 directly contacting the oil smoke is defined as a front wall 113, and the side opposite to the front wall 113 is defined as a rear wall 114.
When the soot of a certain speed passes through the screen device, the soot first contacts the front wall 113 and then flows out through the slits 120 between two adjacent hollow tubes 110. The oil smoke receives blockking of rake 112, and its flow direction takes place the sudden change, and the oil smoke granule of big granule is great turning to the in-process speed drop, attaches to easily on the antetheca 113 of rake 112 department to catch a large amount of oil smoke granules, effectively prevent that the lampblack absorber is inside by oil smoke granule pollution, inside the user need not to clear up the lampblack absorber, guaranteed simultaneously that the lampblack absorber lasts the efficient operation. And finally, discharging the filtered and purified clean oil smoke.
The free end portion a of the horizontal portion 111 and the free end portion B of the inclined portion 112 adjacent thereto are spaced apart from each other and are located on the same vertical plane, so that the soot flowing into the slit 120 can contact the front wall 113 of the inclined portion 112 in the process of rising, thereby improving the soot filtering effect.
