Problems solved by technology

[0004] Since the oil and gas outlet 131 is located at a high place, when the unseparated oil and gas flow into the clean side chamber 120 from the oil and gas outlet 131, the oily air will flow into the connecting pipe 21 from top to bottom. During the moving process, oil is easy to contaminate the inner wall of the housing 11, and the separated oil will gradually accumulate at the bottom of the labyrinth chamber 130, which cannot be returned or discharged, affecting the volume of the labyrinth chamber 130

Abstract

The invention discloses an air filter. The air filter is connected with an oil gas recycling tube, and comprises an outer cover, a filter part which covers the outer cover, an outer housing which is in butt joint with the outer cover, a cover plate which covers the outer housing and a guide tube which is positioned in a clearing side chamber. The outer housing comprises a housing wall part, a separating part which is arranged at the inner side of the housing wall part in a convex mode, and an oil gas introducing hole which communicates with the oil gas recycling tube. The cover plate covers the housing wall part and the separating part; the cover plate, the housing wall part and the separating part are matched to define an oil gas buffer chamber; and one end of the guide tube communicateswith the oil gas recycling tube through the oil gas inlet, and the other end of the guide tube is arranged in the oil gas buffer chamber. The oil gas buffer chamber is arranged in the air filter whileexternal space is not additionally occupied.

Description

technical field [0001] The present invention relates to an air filter, in particular to an air filter for motorcycles. Background technique [0002] refer to figure 1 and figure 2 , the known air cleaner 1 comprises a casing 11, a filter element 12 covering the casing 11 and cooperating with the casing 11 to define a clean side chamber 120, and a filter element 12 located in the clean side chamber 120. And cooperate with the housing 11 to define a cover plate 13 of a labyrinth chamber 130 , and an outer cover 14 matched with the housing 11 and cooperate with the filter element 12 to define a dust side chamber 140 . The casing 11 communicates with the engine 23 through a connecting pipe 21 and an oil vapor recovery pipe 22 . The cover plate 13 is located on the upper side of the clean side chamber 120 and defines an oil gas outlet 131 communicating with the labyrinth chamber 130 and the clean side chamber 120 . [0003] The connecting pipe 21 and the oil and gas recovery...
