Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, an air cleaner includes a housing and a filter 20, the filter 20 is disposed in the housing, and an air inlet pipe 121 and an air outlet pipe 111 are respectively disposed on the surface of the housing.

The shell comprises an upper shell 11 and a lower shell 12, wherein the upper shell 11 and the lower shell 12 are detachably connected. Go up casing 11 and lower casing 12 accessible buckle connection or mode such as threaded connection fix, be convenient for people with go up casing 11 and lower casing 12 and separate to change the clearance to the filter equipment 20 of going up casing 11 and lower casing 12 inside. The outlet pipe 111 is provided at the center of the upper case 11, and the inlet pipe 121 is provided on the surface of the lower case 12.

And a sealing ring 13 is arranged at the joint of the upper shell 11 and the lower shell 12, so that the sealing performance between the upper shell 11 and the lower shell 12 is improved, and air is prevented from leaking out from a gap between the upper shell 11 and the lower shell 12 in the filtering process.

The filtering device 20 comprises a filter element 21 and fan blades 22, the filter element 21 is of a tubular structure, an annular gas channel is formed between the inner wall of the filter element 21 and the inner wall of the shell, an air outlet pipe 111 is communicated with the gas channel, the air outlet pipe 111 is communicated with the inner cavity of the filter element 21, two ends of the filter element 21 are respectively rotatably connected with the bottom surface and the top surface inside the shell, the fan blades 22 are fixedly arranged on the surface of the filter element 21, and the fan blades 22 are arranged in the gas.

Be equipped with bulge loop 211 respectively at the both ends of filter core 21, at last casing 11 and lower casing 12 and the corresponding position in filter core 21 both ends seted up circular recess 122, circular recess 122 and bulge loop 211 looks adaptation to when filter core 21 sets up inside the casing, the bulge loop 211 at filter core 21 both ends sets up respectively in the circular recess 122 of last casing 11 and lower casing 12, and the bulge loop 211 and the circular recess 122 of filter core 21 carry out rotatable coupling, thereby filter core 21 can rotate in the casing.

Air is introduced into the air inlet pipe 121 of the shell, the filter element 21 is arranged in the shell, and an annular air channel is formed between the filter element 21 and the inner wall of the shell, so that the air entering the shell firstly circulates in the air channel, passes through the filter element 21, enters the filter element 21, and then is discharged from the air outlet pipe 111 after being filtered.

Air and flabellum 22 surface that circulates in gas passage contact, under the power effect of air, promote flabellum 22 and filter core 21 and rotate, make filter core 21 keep a pivoted state in the filtering process, let filter core 21 even receive the air impact that intake pipe 121 got into, avoid only filter core 21 one side directly to receive the impact of air, lead to more impurity to attach to filter core 21 one side, influence the filter effect of filter core 21, the effect that can't let filter core 21 comes out by full play, consequently, through rotating filter core 21 in the filtering process, the utilization ratio on filter core 21 surface has also been improved, the life of filter core 21 has been prolonged, play better filter effect.
