NOVELTY - The utility model is new type belongs to the tobacco filter rod production technology field, specifically relates to one kind loading filter screen is added with oxidation graphene and citiggrate filter rod. The filter comprises filter strand, a filter screen, a filter stick forming paper, comprising filter stick forming paper filter rod strand composed of filter, filtering network set is filter strand middle to single or multiple equidistant and on filter, on the filter network load absorbing oxygen graphene material. The utility model is new in type, size controllable filter screen, loading oxidation graphene method, loading amount is easy to control, is excellent and reducing tar-reducing and harm adsorbent of load carrier, at the same time because of network filter adjustable in the amount and location of citiggrate filter stick, so can draw and regulate the citiggrate filter rod. By regulating, filter screen designed at the position of filter stick, it can better realize filter rod absorbing adjust the resistance, at the same time the utility model is new type equipment requirement is simple, easy to implement, and can be citiggrate and the other filter type composite preparation, use, with good practical value.
