Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, an air filter housing includes a housing 1, an air inlet 2 disposed on the housing 1, an air outlet 3 disposed at one end of the housing 1, and a rear cover 4 fastened to one end of the housing 1 far from the air outlet 3, wherein a mounting frame 15 is connected to a bottom of the housing 1. The one end that is close to gas outlet 3 in the shell 1 is connected with guide cylinder 5, the length of guide cylinder 5 is less than shell 1's length, the one end of guide cylinder 5 is connected with the baffle 6 that a plurality of slopes crisscross settings, the outer end and the 1 inner wall contact of shell of baffle 6, hug closely in the guide cylinder 5 and have outer filter core 7, the guide cylinder 5 will be outer filter core 7 and the space between the shell 1 divide into primary filtration district 8 and inferior filtration district 9, form the vent 10 of an slope between the adjacent baffle 6, will be primary filtration district 8 and inferior filtration district 9 intercommunication.
Through set up guide cylinder 5 between outer filter core 7 and shell 1, the one end of guide cylinder 5 sets up baffle 6, can separate into two sections with the space between outer filter core 7 and the shell 1, for prefiltration district 8 and inferior filtering area 9, wherein baffle 6 slope crisscross setting, form vent 10 between the adjacent baffle 6, communicate prefiltration district 8 and inferior filtering area 9, can block great granule and get into inferior filtering area 9, prevent to block up on outer filter core 7, and the filter effect is improved, and service life is prolonged.
