The invention provides a filtration apparatus for printers and copiers. The filtration apparatus comprises a base, a cover body and a filtration screen, wherein one surface of the base is connected to the cover body, the other surface is connected to an equipment wind outlet, and the filtration screen is combined on the cover body. The filtration apparatus is characterized in that the middle of the base is provided with a hollow mold cavity, the side surface of one side on the base border on both sides in the length direction of the mold cavity and facing the cover body is respectively provided with a pair of positioning grooves and a fixation grooves, the left side wall and the right side wall of the base are provided with embedding holes, the middle positions on both ends positioned in the length direction and on the side surface of one cover body side facing the base are provided with embedding feet, a pair of first positioning feet are arranged above and below the embedding feet, a pair of second positioning feet are arranged above and below the pair of the second positioning feet, the embedding feet and the pair of the first positioning feet are respectively embedded into the corresponding fixation groove, the hook foot on the end portion of the embedding foot is matched to the embedding hole in an embedding manner, the pair of the second positioning feet is arranged inside the corresponding positioning grooves on the upper side and the lower side, and the side surface of one cover body side away from the base is provided with a sealing strip. With the filtration apparatus of the present invention, the sealing performance of the filtration apparatus can be improved, and the toner can be prevented from overflowing from the connection gap and the embedding hole.
Description
technical field [0001] The invention belongs to the technical field of office supplies, and in particular relates to a filter device for printers and copiers. Background technique [0002] Printers and copiers are the most commonly used office supplies in daily work, but conventional printers and copiers use toner as printing materials. During the printing process of the equipment, some toner will be discharged from the air outlet, which not only emits peculiar smell, but also Moreover, people may inhale excessive toner powder around the equipment for a long time and cause harm to the human body. Therefore, some filters for filtering the air outlet of printing and copying equipment have appeared on the market, but usually the air volume of the air outlet of the equipment is very small, and the toner is easy to leak from the gap between the filter and the equipment, and the filtering effect is poor. , unable to meet the needs of users. [0003] In the prior art, a kind of "...
