Air cleaner assembly with quarter round plastic intake baffle

Abstract

The invention provides an air filter assembly. A main filter element is arranged in a plastic barrel; a safety core is arranged in the main filter element in the plastic barrel; an air outlet is formed in the lower end of a plastic bottom cover; an air inlet is formed in one side of the plastic barrel; a dust discharging nozzle is arranged on the other side of the plastic barrel; a first sealing ring is arranged between a plastic upper end cover and the plastic barrel; a second sealing ring is arranged between the plastic bottom cover and the plastic barrel; and a plastic air inlet baffle is arranged in the plastic barrel and corresponds to the air inlet. The air filter assembly has a total injection molding structure instead of the original air filter assembly combined by a plastic piece and a metal piece; the whole structure is enhanced; and the production efficiency is greatly improved. The upper end cover and the barrel of the total-plastic assembly are connected with each other by the first sealing ring for damping, the bottom cover and the barrel of the total-plastic assembly are connected with each other by the second sealing ring for damping, the sealing property of the whole assembly is guaranteed, the shock absorption property of the whole assembly is improved, and moreover, the upper end cover, the barrel and the bottom cover cannot directly collide with one another.

Description

technical field [0001] The invention relates to an air filter assembly, which belongs to the technical field of air filters. Background technique [0002] The air outlet of the existing air filter assembly is a plastic part, and the shell is a welded part. The two are buckled on the inner side of the plastic part through the metal part. They are hard links and need to be stamped through a mold. The efficiency is very low and the processing It is easy to cause damage to plastic parts. The mounting bracket is formed by bending a metal sheet, and is connected to the barrel of the assembly through a spot welding process. The mounting space of the bracket is drilled in the metal, and a metal nut is welded in the space. Every step of the welding process of the metal will produce overall deformation. Therefore, the size of metal welded parts is difficult to control, and the scrap rate is high. The metal hook of the upper end cover is completely made of steel wire bending process,...

Problems solved by technology

The windshield is integrated with the air outlet, and it is a full-circle windshield. While blocking the intake airflow, it also blocks part of the filter area, resulting in a low overall filter life.
